Abstract

A junction box assembly for an automobile comprising a main junction box releasably coupled mechanically and electrically to an auxiliary junction box, the main junction box comprising an insulating housing enclosing at least one circuit board providing distribution networks for electrical supplies to main appliances and having plugs or sockets for connection to sockets or plugs terminating main appliance leads, and the auxiliary junction box comprising an insulating housing enclosing at least one circuit board providing distribution networks for electrical supplies to auxiliary appliances, the housing of the main junction box having means projecting from a rear face to attach the main junction box to the bulkhead of an automobile engine compartment.

Claims

1. An automotive electrical junction box means comprising:

a main junction box comprising an insulating housing having a circuit board contained therein,

said housing having oppositely directed parallel main panel members, parallel oppositely directed sidewalls and parallel oppositely directed endwalls extending between said main panel members,

said circuit board extending parallel to, and being between, said main panel members, said circuit board having side edges which extend along said sidewalls and having end edges which extend along said endwalls,

a bus bar conductor in said housing extending between said end edges, circuit board terminal means on said circuit board, said circuit board terminal means comprising terminal tabs and terminal receptacles, said terminal tabs and said terminal receptacles extending normally of said circuit board towards said main panel members,

contact terminals on the ends of said bus bar, said contact terminals extending beyond said end edges of said circuit board and being mateable with complementary terminal means on auxiliary junction boxes and,

mechanical coupling means on said endwalls, said mechanical coupling means being cooperable with complementary coupling means on auxiliary junction boxes.

2. Junction box means as set forth in claim 1, said insulating housing of said main junction box comprising two housing parts, each of said housing parts comprising one of said main panel members and flanges extending therefrom, said flanges forming said endwalls and said sidewalls of said housing.

3. A junction box means as set forth in claim 1, said terminal tabs extending normally of, and beyond, one of said main panel members, said terminal receptacles extending towards the other panel member and being fully contained in said housing, said other panel member having openings therein in alignment with said terminal receptacles to permit insertion of complementary terminal devices into said terminal receptacles.

4. Junction box means as set forth in claim 3 comprising auxiliary junction boxes coupled to said main junction box by said coupling means, said main junction box providing distribution networks for electrical supplies to main appliances, said auxiliary junction boxes providing distribution networks for auxiliary appliances.

5. Junction box means as set forth in claim 1, said mechanical coupling means on said endwalls comprising latching apertures dimensioned to receive complementary latch arms with latching detents.

6. Junction box means as set forth in claim 5, said contact terminals on said ends of said bus bar comprising fork contact extending normally of said endwalls whereby said main junction box is adapted to receive said auxiliary junction boxes upon movement of said auxiliary junction boxes towards said endwalls in the plane of said main junction box.
