Electrical junction box
First Claim
1. An electrical junction system comprising a wiring board carrying a plurality of bus bar conductors each having an end extending upwardly therefrom, a case member covering the upper side of said wiring board and having holes into respective ones of which the ends of said bus bar conductors project with said case member covering said wiring board, said case member also having terminal receiving seats adjacent to the respective upright holes and extending substantially horizontally, a printed circuit board carrying functional parts and having one side edge from which a plurality of tab-like contactors project in side-by-side relationship, each of said tab-like contactors having at a longitudinally intermediate portion thereof an engaging tab extending upright therefrom, a cover member affixed to the circuit board and covering and protecting said functional parts, said cover member having a load bearing hole receiving said engaging tabs of said tab-like contactors and bearing the adjacent portion of said tab-like contactors upon the occurrence of horizontal relative displacement between said cover member and said tab-like contactors, intermediate terminals each having a substrate bent into L-shape and receptacle-like contactors provided at both ends of said substrate, one of said receptacle-like contactors of each of said intermediate terminals being fitted into a corresponding hole in said case member to contact with the end of the bus bar conductor projecting thereinto, the other receptacle-like contactor being supported on the corresponding terminal receiving seat of said case member, said tab-like contactors of said circuit board being inserted into said other receptacle-like contactors to establish contact therebetween upon sliding of said circuit board horizontally.

Abstract
An electrical junction system for automotive internal wiring has a wiring board provided with branching conductors formed by a multiplicity of bus bars on an insulation plate, the branching conductors being adapted to be connected to electric wires in a wiring harness to form branching electric circuits. The electrical junction system has a printed circuit board detachably mounted on the wiring board, the printed circuit board generally or inclusively carrying a plurality of circuits incorporating a multiplicity of function parts which are used semi-permanently such as relays and associated control elements.
