Benefits of technology

[0005]A first aspect of this invention is the creation and provision of an improved housing for electrical devices having a non-integral; i.e., separately formed electrical cable outlet port member which provides the desired de-tensioning characteristic but which, because it is formed separately from the housing, can be economically and quickly replaced if broken during the installation or servicing procedures.
[0007]Another aspect of the invention is the provision of an inexpensive, easily formed busbar for mounting within an electrical device housing to receive a plurality of conventional circuit breakers and make electrical connections therewith. 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.

Problems solved by technology

The problem with this approach is that the opposed fingers which make up the anti-tensioning device are frequently broken off during installation.
Where the housing is complex, such a practice is costly and time consuming.

Embodiment Construction

[0019]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.

[0020]Referring now to FIGS. 1 through 3, a molded plastic housing 10 of the size, weight, and configuration suitable for use as an electrical distribution center in recreational vehicles is shown. The housing 10 is injection molded from a suitable phenolic resin to exhibit a decorative and functional front peripheral flange 12, a separate snap-in cover 14 having edge tabs 13 and an access patch 16 having edge tabs 17 which cooperates with the rem...

Abstract

A housing for electrical devices such as connectors, circuit breakers, and fuse panels. A cable outlet port member is separate from the housing to provide unidirectional resistance to movement of a cable relative to the housing. The non-integral relationship permits the members to be replaced in the event of damage. A busbar formed by a stamping and bending operation is also disclosed for use in combination with conventional circuit breakers.

Description

FIELD OF THE INVENTION[0001]This invention relates to housings for electrical devices such as connectors, fuses, and circuit breakers and, more particularly, to an improved housing having a non-integral cable de-tensioning member which is removably attached to the housing for simple economical replacement in the event of breakage. This invention also relates to an improved busbar for attachment to circuit breakers and to a method of making such a busbar.BACKGROUND OF THE INVENTION[0002]Housings for electrical devices, such as connectors, circuit breakers, and fuse panels, are used in many applications, including recreational vehicles such as motor homes and boats. In a typical application, the housing receives multiple cables for connection to devices within the housing and to carry electrical power to a number of devices outside of the housing. It is good practice to use de-tensioning devices within the housing to insure that electrical connections between the cables and the device...
