    MODULAR CONNECTION FUSE BLOCK
    This application is a partial continuation of the U.S. application with serial number 09 / 102,100 filed on June 22, 1998.
    This invention relates to power distribution blocks in general. In particular, the invention relates to a fuse block with a common power bus.
    Power distribution blocks are generally used in the prior art to collect a plurality of circuit elements, such as fuses, at one central location.
    Several fuse blocks are currently available as collapsible modules that form a multi-fuse panel. These collapsible modules become excessively large if a large number of fuses have to be fitted in the block. Compiling the modules is costly and labor-intensive.
    With existing fuse block designs, it is also common for the user to individually wire each circuit within the power input block. If it is desired that more than one circuit with the same power source be supplied with power, a temporary connecting wire is installed for this purpose. These multiple wiring procedures and the installation of a temporary connection wire are expensive, labor-intensive and cost a lot of time for the user. In addition, additional circuits require the use of wiring with a larger gauge in order to cope with the added ampere load. The use of larger gauge wiring is expensive, difficult to process and requires more space on the panel to install the fuse block.
    A further problem with existing designs is the inability to protect the components of the fuse block against contamination, in particular from liquids. Although "splash guards" are available for some existing designs, these screens are shaped as additional components that must be bolted in place. This type of splash screen has certain drawbacks, since this screen requires additional space on the panel to be secured and provides additional labor costs for its installation.
    U.S. Patent No. 4,944,691 to Morach provides a holder for removable circuit elements. The holder comprises a metal busbar with a plurality of fuse holders integrally formed therewith. Output termination points are provided that extend laterally from the busbar. A screen member is provided that includes openings in the top for inserting fuses.
    U.S. Patent No. 4,599,679 to Baader includes a fuse busbar assembly that includes a busbar that is formed as two separate components stacked on top of each other. The busbar components include tails bent in the opposite direction that cooperate to receive fuse terminals for an electrical connection thereto. A screen member is provided that includes a plurality of openings for receiving fuses. This construction requires a rather precise formation and composition so that the tails receive the fuse connection points in the correct manner and thus interlock. If one tail is deformed or damaged, it may be necessary to replace the entire busbar component. In addition, the housing and the. screen not for the effective isolation of the circuit elements or fuses of pollutants.
    U.S. Patent No. 5,438,310 to Ikari provides a fuse box formed by a plurality of discrete components that are mechanically connected to each other. This construction is excessively complex, costly to manufacture, and less compact compared to the present invention.
    U.S. Patent No. 4,842,534 to Mobley et al. Provides a fuse / busbar assembly with a plurality of (female) terminal components connected thereto. The physical connection of the terminal components to the busbar provides an increase in costs and labor compared to the manufacture of the present invention.
    In a preferred embodiment of the invention, an assembly of a power block comprises an insulating housing with at least a first modular housing part and a second modular housing part and at least one electrically conductive bus part with a longitudinally extending base and a plurality of terminal contact blades extending from the base. The base of the bus member has a location for the electrical connection to a power source and a longitudinally extended U-shaped channel defined by opposed legs. A plurality of terminal contact blades extend from the legs of the channel and include a plurality of locations for electrical connection to a plurality of removable circuit elements. A plurality of separate connection elements are located within the housing and each of the connection elements is configured to connect a connection terminal sheet of the bus to a terminal contact point of one of the respective removable circuit elements.
    The modular construction of the insulating housing allows a wider range of busbars and different numbers of poles in a compact, easily assembled unit with low costs. The insulating housing comprises at least a first end portion, a second end portion and a middle portion that is coupled to the first end portion and the second end portion. The modular portions are formed for snap-fit coupling with each other, and each of the portions includes a plurality of electrical access openings that provide access to respective locations of the terminal contacts of the conductive bus member.
    The modular housing portions include male and female couplings configured to connect to each other to form a housing of a suitable size for containing a specified current rail or power rails for power input. A tongue and groove assembly securely connects the portions to each other, and by adding or removing middle portions of the modular housing, a wide range of power distribution blocks are provided for containing different busbars and different numbers of poles in a low cost system, that is versatile and easy to put together.

    Certain components of an assembly of a power distribution block 1 according to the present invention are shown in Figure 1. An insulating housing 5 receives a collection tray part 15. A "splash-proof" screen 10 is provided on the housing 5 for enclosing the interior thereof.
    The insulating housing 5 is, in one embodiment, preferably built as a one-piece component. It is meant that the term "one-piece" means a monolithic one-piece part. The housing 5 can be constructed from any suitable material. A preferred material is a strong, heat-resistant, chemical-resistant plastic.
    The housing 5 can have one or more mounting flanges 125, each having an aperture 127, with a screw thread arranged on the inside thereof (Figure 5), for receiving a suitable fastener (not shown). The housing 5 is also provided with an upright side wall 115 and an inner compartment 120.
    As shown in Figure 2, one or more electrically conductive bus members 30, 35 are inserted into the lower part of an insulating housing 5.
    The assembly of a power distribution block 1 may comprise a plurality of electrically conductive bus members 30, 35, each comprising means for connecting to a power source. One such means is a threaded nail 40, although it is also possible to use other types of connecting elements. If there are more than one conductive bus members 30, 35, they are separated from each other by a hole or by an electrically insulating separation member 37. By using separate conductive bus members 30, 35, it is possible to provide power to the assembly of a power distribution block 1 from a multitude of different sources.
    For example, when used in vehicles, it is often advantageous to provide power to some circuit elements at all times from a power source (e.g., a battery) and to provide power to other circuit elements only at certain times, e.g. if the vehicle ignition system is activated. Although the embodiment shown in Figure 2 shows a 12-pin bus 30 in combination with a 4-pin bus 35, the number of poles provided for each of the bus parts 30.35 can vary over a wide range depending on the requirements of the specific system that is supplied with power. By way of example, 4, 6, 8, 10, 12, 16, 20 and 24-pole configurations are possible. More than two bus parts can also be used. Alternatively, a single busbar element can be used.
    Details of a representative bus member 45 made in accordance with the present invention is shown in Figure 3. Busbar members 30, 35 may be constructed in a manner as described below with reference to the representative busbar 45. The bus member 45 is made of any suitable electrically conductive material. Preferably the material is capable of supporting relatively large flows. Such a suitable material is the C1100 alloy, which consists of 99.9% pure copper with an H hard additive. The bushing member 45 has a U-shaped base 55 extended in the longitudinal direction. One or more openings 50 are provided in the base 55 for receiving a suitable electrical connection element, such as the threaded nail 40. An opening 50 may be provided at each end of the base 55 are mounted. A nail 40 can be located at each end, providing the most suitable location for connection to a power source and allowing connection to it. The base 55 may optionally include one or more holes 70 through which a suitable securing element (not shown) may pass for connecting the bus member 45 to the housing 5. A plurality of power output wires 25 are connected to the block assembly 1 in a manner described more fully below.
    As shown in Figure 3, the conductive bus member 45 also includes a plurality of terminal contact blades 60 extending from the legs of the U base 55. A plurality of connection formations, preferably in the form of cut-away pieces 65, are in the legs of the U-shaped base 55 disposed at the location of each terminal contact sheet 60. The construction of the bus member 45 provides several advantages. The terminal contact blades 60, for example, enable attachment of a plurality of circuit element, as will be described more fully below. These circuit elements can be powered by a single electrical connection to the base 55, rather than resorting to interconnection wires or individual circuit wiring diagrams. The bus member 45 can carry large currents with a small separation of circuit elements without overheating, while also providing reliability and compactness.
    The manner in which the bus member 45 can be attached to the insulating housing 5 is further explained with reference to Figure 4.
    Slots 75 are provided in the bottom of housing 5 for receiving the terminal contact blades 60. These slots 75 may be numbered to allow identification of the individual circuit elements attached to each blade 60.
    A mounting projection 80 is integrally formed with the housing 5 and is located at each slot 75 for providing a snap-fit coupling to the bottom 65 portions of the bushing member 45. A bushing 90 for mounting the bushing may also be provided along the bottom of the housing 5. Optionally, holes 85 may be provided in the beam 90. Holes 85 correspond to the optional mounting vessels 70 in base 55 of the bus member 45 and receive appropriate mounting means (not shown) for providing additional means for fixing the bus part 45 to the housing 5.
    The housing 5 further comprises a pair of integrally formed parallel legs 95. Legs 95 define a plurality of open chambers 100 that allow the passage of connecting elements, as will be explained in more detail below.
    The other side of housing 5 is described with reference to Figure 5. A plurality of passages 120 are located in the inner compartment 120 for receiving a load-side contact of a removable circuit element. Also, a plurality of compartments 150 are arranged within the inner compartment 120. Compartments 150 house a plurality of connecting elements 155 (Figures 6 and 7). The slots for terminal contact blades extend from the bottom of housing 5 and are connected to the bottom of compartments 150.
    As in Figures 6 and 7, a separate connecting element 155 is arranged in each compartment 150. The terminal contact blades 60 extend into the slots 150 through the slot openings 75. Each connecting element 155 fits over a terminal contact blade, a way best illustrated in Figure 7. Connecting elements 155 are formed of any suitable material, such as stainless steel. A terminal on the input side 178 of a removable circuit element 177 can be received between the spring fingers 160 of the terminal element 155 and the terminal terminal 60. In this way, a direct electrical connection is made between a terminal terminal 178 and a terminal terminal 60. The terminal element 155 is not intended as a current-carrying element.
    A female connection element on load side 165 is received in each of the passages 140. See Figure 8. A connection point on load side 159 can be received between two curved contacts 175 of the female connection element 165. A pair of locking members 170 protrude laterally from the female connection element 175 and rest on ridges 145 arranged in the compartments 140. This construction prevents the female connecting element 16 from passing through the bottom of the open chambers 100. A plurality of retaining loops 167, 169 are provided at the lower end of connector 165, which receive and retain the output wires W in a manner well known in the art.
    The female terminal contact connector 165, shown in Figure 8, is similar to a terminal contact point of a "Packard" type. However, the present invention is not dependent on the specific type of load side connection element being used. Various designs of connection elements are possible for connection to the contact point 179 on load side.
    In one embodiment, the removable circuit element 177 may comprise a securing element.
    Various types of fuse elements can be used. By way of example, an ATC ™ type fuse (available from Cooper Industries-Bussmann Division) can be effectively used in combination with the power distribution block of the present invention.
    In an alternative embodiment, the removable circuit element (s) may comprise a circuit break element 177A which is schematically shown in Figure 6A.
    As best illustrated in Figures 1 and 9, a sump tray 15 can also be located inside the inner compartment 120 of housing 5. Sump tray 15 is preferably formed of an insulating material similar to the material of housing 5. Sump tray 15 is provided with a plurality of protruding retaining members 185 which are received with a snap fit in a plurality of corresponding retaining openings 135 in the housing 5 (Figure 5). The correct insertion of the receptacle 15 into the internal compartment 120 can be ensured by providing at least one protruding retaining member 185 which engages with a corresponding retaining opening 135, this only being the case if the receptacle 15 is correctly oriented is relative to the house 5.
    The receptacle 15 is provided with a plurality of openings 190 which receive the removable circuit elements 177. The apertures 190 may be numbered so as to correspond to the numbering of the slots 75 for terminal contacts, thereby enabling identification of the circuits and of the circuit elements 177.
    The apertures 190 also include the enlarged regions 195, which allow the insertion of a removal tool (not shown) for retracting the load element connecting element 165.
    Due to this structure, the collecting tray 15 guides and organizes the removable circuit elements 177. The collecting tray 15 also serves to enclose and hold connecting box elements 155 and the female connecting elements 165.
    In an alternative embodiment, the assembly of a power distribution block 1 may also comprise additional means for securing the female connecting elements 165. A possibly added locking member 200 is shown in Figure 10. Locking member 200 may be formed of any suitable material, such as an insulating material to the material of housing 5. Locking member 200 includes a plurality of protrusions 205 adapted to fit with corresponding retracted openings of slot heads 105 provided in the side surfaces 110 of legs 95. The protruding locking members 207 include snap-fit tabs 210 which hold the locking member 200 when it is arranged in the openings 105. The protruding locking members 207 are formed to couple with a coupling portion or edge 180 formed on the female connecting elements 165 (Figure 8). The locking element 200 further functions to hold the female connecting elements 165 within the open chambers.
    Another aspect of the present invention relates to the provision of a lid member 10 which effectively seals the inner compartment 120 of the housing 5, thereby preventing contamination of the circuit elements 177 and the electrical connections therein. Lid part 10 may be formed of any suitable material such as an insulating material that is similar to the material of the housing 5.
    As best illustrated in Figures 1 and 11, the lid 10 can include a plurality of gripping protrusions 13 that are received with a snap-fit coupling in the corresponding openings 16 provided in the housing 5. Lid 10 can also include an integral band 11. The tape 11 has an aperture 12 located at one end thereof for receiving a suitable shutter F. This construction prevents the screen from being lost or falling when it is removed. The screen part 10 can further be provided with side walls in the form of a U-shaped channel 14. The U-shaped channel 14 is made for receiving the upright side wall 115 of the housing 5. The assembly forms an effective seal between the screen 10 and side wall 115 which effectively excludes contaminants from the inner compartment 120, in particular splashed liquids. Although this is specifically illustrated, the screen 10 may include means for further enabling gripping or removal thereof, such as between, protrusions, notches, and so on.
    Figure 12 shows a perspective top view of another embodiment of a power distribution block 300 comprising an insulating body 302 and an organizer bin 304 including indications (not shown) such as numbers for making desired electrical connections to power distribution block 300. More particularly, bin 304 defines at least partially a plurality of openings 306 that receive removable circuit elements, such as elements 1.77 shown and described above. The openings 306 of the tray are, in one embodiment, numbered such that they correspond to the numbering of terminal contact sheet slots (not shown in Figure 12 but similar to the slots 75 shown in Figure 4) by enabling identification of the circuits and circuit elements 177 to make.
    If desired, power distribution block 300 further includes a protective lid (not shown in Figure 12) such as a splash-proof screen 10 described and illustrated above. An upright side wall 308 extends around an upper circumference of the insulating housing 302 for a sealing coupling with the protective screen, and further for defining an inner compartment 310 for making electrical connections.
    Unlike the entire one-piece monolithic insulating housing 5 of power distribution block 1 (shown and described above), the insulating body 302 of power distribution block 300 is modular and includes a first end portion 312, three middle portions 314, and a second end portion 316 coupled together to form the internal compartment 310 that receives the bin 304. As can be seen clearly from Figure 12, the power distribution block comprises twenty openings 306 for electrical connections, or in other words a 20-pole distribution block is provided for accommodating a power input bus (not shown in Figure 12) or a combination of power input buses (not shown). in Figure 12) with twenty terminal contact blades such as 0 terminal contact blades 60 of the busbar 45 (shown and described above in relation to Figure 3). The modular housing portions 312,314,316 enable snap-together assembly of the housing 302 for placing different busbar components or added busbar components and therefore for providing a practically unlimited number of pole variations for specific applications. As will become apparent hereinafter, each housing portion 312,314,316 comprises two pairs of connection openings, or four openings each, and the total number of poles of 0 power distribution blocks 300 can be varied by adding or subtracting central portions 314 from the assembly.
    Fig. 13 is an exploded view of the housing of the modular power distribution block 302 illustrating this assembly of end portion 312, middle portions 314, and end portion 316. As shown in Figure 13, end portion 316 is coupled to a middle portion 314 to form a first sub-assembly 320, and two middle portions 314 are coupled to each other to form a second sub-assembly 322. The term sub-assembly used herein simply refers to joining two modular house sections together. It is clear that housing portions 312,314,316 could be assembled in any order to form a number of different combinations or subassemblies of modular housing portions. The assemblies shown in Fig. 13 are therefore shown for illustrative purposes only and are in no way intended to limit the invention to a particular combination of subassemblies when forming the housing of power distribution block 302.
    Referring again to Figure 13, the first subassembly 320 and the second subassembly 322 are arranged to engage with each other, and the second subassembly 322 is provided to engage with end portion 312. An overlapping tongue and groove 324 assembly is used to lock the housing portions 314 with end portions 312,316 and the subassemblies 322 and 324 together. A male tongue member 326 is provided at the major edges of the respective housing portions for engagement with a female groove or slot 328 of adjacent portions. Tongues 326 extend below the major edges of adjacent portions and are received in additional slots (not shown in Figure 13) within the grooves 328 of interlocking portions such that the interlocking ends of adjacent portions slightly overlap and form a certain, structurally stable fit with each other. In one embodiment, portions 312,314,316 adjust tightly to a suitable resistor that allows assembly and disassembly by hand without the use of tools.
    Figures 14-16 illustrate individual modular housing portions 312,314,316, respectively. Referring to Figure 14, the end portion 312 includes four openings for electrical connections 306, a revolving upright wall portion 340 that forms an end portion of compartment 320 (shown in Figure 12) and tongues 326 extending from leg extensions 342 to connect to a modular housing center portion 314 The parallel legs 344 extend downwardly from wall portion 340 to define a plurality of open chambers (not shown in Fig. 14 but similar to the chambers 100 shown and described above with respect to Fig. 4) that facilitate the passage of electrical enable connecting elements as described above.
    Although the end portion 312 is described with four electrical connection openings 306, it is emphasized that the end portions 312 with more or fewer than four couplings for electrical connections can be used without departing from the object and scope of the present invention.
    Referring to Figure 15, the center portion 314 includes four openings for electrical connections 306, the upstanding parallel wall portions 346 which further define the compartment 320 (shown in Figure 12) when the center portion 314 is coupled to an end portion 312 or 316. A first coupling side 347 of middle portions 314 includes a pair of coupling tongues 348 extending from the leg extensions 350 to engage with another modular middle portion of a housing 314 or with an end portion 316, which is further described below. A second coupling side 352 includes grooves or slots 328 (shown in Figure 13) that extend to the opposite tongues 348 for connection to another middle portion) 314 or to an end portion 312 (shown in Figure 14). The parallel legs 354 run downward from wall portions 346 to define a plurality of open chambers (not shown in Figure 15 but similar to the chambers 100 as shown and described in relation to Figure 4) that allow the passage of electrical connection elements, as described above.
    Although the middle portion 314 is described with four openings for electrical connections 306, it is possible that the middle portions 314 have more or fewer openings for electrical connections without departing from the scope of the present invention. Thereby, the middle portions 314 need not have the same number of openings if more than one middle portion is used for a particular application such as a housing 302 shown in Figures 12 and 13. Thus, for example, a middle portion with four openings for electrical connections S06 can be used with a central section with six openings for electrical connections. Therefore, larger and smaller middle portions can be used separately with respect to each other or used in combination with each other to effectively meet the specifications of a particular application.
    Referring to Figure 16, the end portion 316 includes four openings for electrical connections 306, a circumferentially raised wall portion 360 for forming an end portion of compartments 320 (shown in Figure 12) and a groove 362 for receiving the tongues 354 from the middle portion 314 (shown in Figure 15) or for accepting the tongues 326 from another end portion 312. The parallel legs 364 run downwardly from the wall portion 360 to define a plurality of open chambers (not shown in Figure 14 but equal to the chambers 100 as shown and described with respect to Figure 4) which allow the passage of electrical connection elements as described above.
    Although end portion 316 is shown with four openings for electrical connections 306, it is emphasized that also 316 with more or fewer than four openings for electrical connections can be used without departing from the scope of the present invention.
    It should now be appreciated that the modular housing portions 312,314,316 can be connected together by coupling the respective male and female ends of the portions 312,314,316. Thus, assembling portions 312,314,316 as shown in Fig. 13 results in a regid housing 302 (shown in Fig. 12) with a selected number of openings for electrical connections 306 and a corresponding number of open chambers running downwardly from an opposite side of housing 302 for passage of connecting elements. Once the modular housing 302 is assembled in this manner, the assembly of a power distribution block 300 (shown in Figure 12) operates substantially as described above with respect to the power distribution block 1.
    Figure 17 shows a bottom perspective view of power distribution block 300 comprising an assembled modular housing 302 and first and second input current rails 380, 382 coupled to a lower side of the modular housing 302 with threaded fastening elements 384 and further comprising respective connection points for nails 386, 388 for power input connections via the nuts 390, 392. It is appreciated that other connection schemes and securing elements may be used in place of the connection studs 386, 388 in further embodiments without departing from the scope of the present invention.
    20484.
    As indicated above, the first and second conductor rails 380, 382 enable the provision of power to certain circuit elements from a power source (e.g., a battery) at all times and the provision of power to other circuit elements only at certain times, such as in vehicle ignition systems.
    In the illustrated embodiment, bus member 380 is similar to busbar part 45 (shown and described with respect to Figure 3) but it comprises six terminal contact blades, while bus member 382 is similar to busbar part 45 (shown and described with respect to Figure 3) but includes fourteen terminal contact blades 60. Thus, a total number of twenty terminal contact blades is provided for 20-pole operation of power distribution block 300 through twenty access openings 306 (shown in Figure 12) on an opposite side of the modular housing 302. However, it is recognized that the modular structure of the housing 302 allows a wider range of options for the bus component to adapt to a particular application.
    For example, an added center portion 314 can be used to adapt a first busbar with sixteen terminal contacts and a second busbar with eight terminal contacts for 24-pole operation of the power distribution block. One of the middle portions 214 could, as another example, be removed from the power distribution block 300 to form a 16-pole distribution block with, for example, two input current rails with eight terminal contacts each. In a further example, two added center portions 314 can be added to the power distribution block 300 to accommodate a third power input current rail with eight terminal contact blades added to the current rails 380, 382. Finally, the modular construction of the housing 102 can be applied similarly with a variety of separate power input busbars. Although only a limited number of examples have been shown, it should now be understood that the modular body 302 allows a practically unlimited number of pole combinations for different applications in a simple, compact, easily assembled package with low costs.
    Although the invention has been described with reference to various specific embodiments, those skilled in the art will recognize that the invention can be applied with modifications within the scope and scope of the claims.
