Abstract

Abstract A junction box for a motor vehicle electrical system for coupling electrical conductors extending from the rear of a vehicle with conductors extending to the front of a vehicle, comprising an integrally moulded body having removable end, top and bottom walls and an intermediate plate which can be slidably engaged in guides in the side walls of the body. The removable end and bottom walls are provided with connector units for connecting electrical conductors of the external circuit to the junction box. These connector units are interconnected internally by flexible printed circuit connectors which also make contact with actuating elements, such as relays, and with printed circuit fuses mounted in sheets on pivoted support plates by means of which fuse changing is facilitated.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 340 words
A junction box for a motor vehicle electrical system, comprising: a hollow unitary main body incorporating, with reference to a given orientation: a first end wall, two symmetrical side walls each connected along a first edge to a respective opposite edge of said end wall, a transverse bridging member interconnecting corresponding corners of said side walls at a second edge thereof, opposite said first edge, means defining first and second aligned guideways in each said side wall, said guideways extending between said first and second edges of said side walls, said first guideways being adjacent the lower edges of said side walls and said second guideways being located at a position part way up the height of said side walls a member forming a bottom wall having a rim slidably mounted in said first guideways of said side walls closing the bottom of said unitary body, an intermediate plate member having two parallel side edges slidably mounted in said second guideways of said side walls of said unitary body, a transparent lid member removably attached to said intermediate plate member closing the top of said unitary body, a member forming a second end wall removably attached to said body along the edges of said two side walls opposite the edges connected to said first end wall so as to extend substantially parallel to said first end wall, said second end wall overlying the edges of said bottom wall member and said intermediate plate member to hold these in position against withdrawal along said first and second guideways, first and second electrical connector units respectively mounted on said second end wall member and said bottom wall member, said connector units having means for connection to terminals of the conductors of a motor vehicle electrical system, printed circuit fuse means carried by movable supports on said intermediate plate member, and printed circuit connector means electrically connecting said first and second electrical connector units together, within said body and electrically connecting said printed circuit fuse means to said connector units within said body.
Claim 2
Dependent Claim 340 words
A junction box for a motor vehicle electrical system, comprising: a hollow unitary main body incorporating, with reference to a given orientation: a first end wall, two symmetrical side walls each connected along a first edge to a respective opposite edge of said end wall, a transverse bridging member interconnecting corresponding corners of said side walls at a second edge thereof, opposite said first edge, means defining first and second aligned guideways in each said side wall, said guideways extending between said first and second edges of said side walls, said first guideways being adjacent the lower edges of said side walls and said second guideways being located at a position part way up the height of said side walls a member forming a bottom wall having a rim slidably mounted in said first guideways of said side walls closing the bottom of said unitary body, an intermediate plate member having two parallel side edges slidably mounted in said second guideways of said side walls of said unitary body, a transparent lid member removably attached to said intermediate plate member closing the top of said unitary body, a member forming a second end wall removably attached to said body along the edges of said two side walls opposite the edges connected to said first end wall so as to extend substantially parallel to said first end wall, said second end wall overlying the edges of said bottom wall member and said intermediate plate member to hold these in position against withdrawal along said first and second guideways, first and second electrical connector units respectively mounted on said second end wall member and said bottom wall member, said connector units having means for connection to terminals of the conductors of a motor vehicle electrical system, printed circuit fuse means carried by movable supports on said intermediate plate member, and printed circuit connector means electrically connecting said first and second electrical connector units together, within said body and electrically connecting said printed circuit fuse means to said connector units within said body.
Claim 3
Dependent Claim 200 words
The junction box of claim 1 wherein said printed circuit fuse means comprise respective printed circuit sheets and said movable supports carrying said printed circuit fuse means comprise respective plates pivotally mounted between upstanding lugs on said intermediate plate member for turning movement about an axis parallel to said intermediate plate member, there also being means defining a longitudinal slot in said intermediate plate member extending parallel to said axes of turning movement of said printed circuit fuse support plates, the ends of said printed circuit connectors extending through said elongate slot whereby said printed circuit fuse sheets are contacted therewith when said fuse support plates are turned to a position substantially parallel to said intermediate plate member, and pivoted levers mounted on brackets carried by said intermediate plate member and each pivotable about an axis perpendicular to the plane of said intermediate plate member between a first position where it extends over a respective said fuse support plate when the latter is in the position parallel to said intermediate plate member whereby to hold the associated said fuse plate in said position, and a second position where it does not obstruct the pivoting movement of said associated fuse plate.
