This application is a division of Ser. No. 09/752,191, filed by the same inventors on Dec. 29, 2000, and entitled “IMPROVED ELECTRICAL DISTRIBUTION CENTER WITH NON-INTEGRAL ROMEX RETAINER COMPONENT.
This invention relates to housings for circuit breakers and, more particularly, to an improved busbar for bringing power to circuit breakers mounted in a housing and to a method of making such a busbar.
Housings for electrical devices, such as connectors, circuit breakers, relays and fuse panels, are used in many applications, including recreational vehicles such as motor homes and boats. In a typical application, the housing carries a number of conventional circuit breakers in a side-by-side or stacked parallel arrangement and a door or cover to close and partially seal the housing. The breakers are physically mounted on a busbar made of conductive metal with spaced parallel fingers called “stabs” which project into spring contacts within each breaker body.
Typically such a busbar is made by extruding a long aluminum element having the desired cross section, i.e., a base plate with parallel upstanding ribs, and cutting the extruded section into short, identical pieces. Such a process of manufacture is expensive in that it requires the creation of an extrusion die, the purchase of an extrusion press, and further in that it requires significant hand labor to carry out the various operations involved in the manufacturing process.
A first aspect of the present invention is the provision of an inexpensive busbar for mounting within an electrical device housing to receive a plurality of conventional circuit breakers and make electrical connections therewith. A second aspect of the invention is a method by which the improved busbar can be manufactured by creating an inexpensive stamping and thereafter bending portions of the stamping to produce the plurality of spaced, parallel stabs. In the configuration disclosed herein, the spacing between the stabs is independent of the height of the stabs.
Other objects, advantages and applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings.
The description herein makes reference to the accompanying drawings wherein like reference numerals refer to like parts throughout the several views, and wherein:
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiments but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law.
Referring now to
The housing is further provided with an integral, rigid, rear panel 18 having formed therein an essentially rectangular opening having a peripheral edge 20 adapted to removably receive, a molded plastic outlet port member 22 having electrical cable ports 23 defined by opposed resilient plastic fingers 24 which are designed to unidirectionally resist passage of an electrical cable 43 there through and to omit permit passage of the cable in the opposite direction. Holes 26 are provided in the member 22 to receive screws 27 which enter into bosses 28 formed in the panel 18 so that the port member 22 may be removably attached to the housing 10. As shown in
Housing 10 further comprises an interior panel 30 which essentially divides the interior of the housing into AC and DC sections, the AC section being the larger section on the left, as shown in FIG. 1. On the DC side, a fuse panel 32, receiving a plurality of standard automotive-type fuses 34, is provided. On the AC side, the panel 30 is configured to receive an aluminum busbar 36 hereinafter described in detail. Conventional circuit breakers 38 are mounted on the stabs of the busbar 36 in a spaced, parallel stack as shown in FIG. 1. Obviously, other configurations and/or interior arrangements may be provided.
Additional electrical connective devices such as the junction block shown at 40 may be provided on the interior of the housing 10. In addition, the rear panel 18 is provided with knockouts 42 for cable muting purposes.
Because of the non-integral nature of the member 22 with the housing 10, a number of members 22 may be taken to the job site and readily substituted into the place of the original member should one or more of the fingers 24 be broken off during the installation or servicing procedure. When this occurs during servicing, the non-integral nature of the member 22 allows it to be removed and replaced without loss of the de-tensioning feature which good electrical service and installation practice requires.

The housing 50 receives any of a number of different types of electrical devices, in this case, a strap-in bracket 58 carrying connectors 60. A top panel 62 of the housing 50 is provided with knockouts 64 for cable routing purposes. A cover 66 of injection molded plastic construction is provided with edge loops 68 operating with tabs 70 on the housing 50 to provide a snap-on relationship.
