A wire harness assembly including a wire harness and a junction box. The junction box contains a plurality of junction box terminals and it also carries an attachment unit projecting outwardly. The attachment unit has a plurality of openings in its outer surface through which the junction box terminals project. One end of the terminals is in contact with the internal circuit of the junction box and the other is a pair of cutting blades into which the wire is inserted. An intermediate section of the wires is attached in accordance with the foregoing, and the ends are inserted into a plurality of connection boxes. The openings may be in multiple rows, offset transversely from each other. This permits inclusion of a large number of terminals in a relatively small space.

Wire harness assembly

An electrical assembly includes a housing containing a plurality of electrical components constituted by blocks, each block having a bus-bar and a protruding electrical connection. The electrical connections coincide substantially at the centre of the housing in a stack and are fastened together to directly connect the bus-bars. Preferably, the electrical connections are connected by a screw and bolt fastener passing through aligned apertures of the connections.

Branching connection box for electrical circuits

A bus bar of a branch joint box, which is formed by punching a metal sheet into a preset pattern of a circuit and is formed, at a predetermined location of the circuit, with a tab to be plated with metal having excellent electrical conductivity such that a connector of a wiring harness is connected to the tab through plug-in, including a separate bus bar portion which is formed by punching a separate metal sheet and includes the tab; wherein after the tab of the separate bus bar portion has been plated with the metal, the separate bus bar portion is inserted into a predetermined portion of the bus bar so as to be mounted on the bus bar.

Bus bar of branch joint box

A branch joint box comprising: a base plate; and a pair of connector coupling portions which are, respectively, formed on opposite faces of the base plate so as to confront each other; the base plate being formed with a plurality of insertion openings for inserting therethrough bus bars each including an elongated base portion and at least one pair of tabs extending from opposite sides of the base portion, respectively; the insertion openings extending through the base plate so as to communicate the connector coupling portions with each other; wherein the bus bars are secured in the insertion openings, respectively such that the tabs project into the connector coupling portions, respectively.

Branch joint box

An electric connection terminal can prevent electric ereosion caused in some equipment made of an aluminum material and attached to a car body for electric conduction of the equipment through the terminal such as an earth bracket which connects an earth line to the car body. The terminal comprises a first attaching member (1) made of an aluminum material and having a connecting portion (4) of a car body at the top end and a coupling portion (6A) at the bottom end, a second attaching member (2) made of a brass material and having a connecting portion (5) of an earth line at the top end and a coupling portion (6B) at the bottom end, and a water-proof layer (3) molded by a plastic resin for interconnecting said coupling portions (6A, 6B) of said first and second attaching members (1, 2) by embedding said portions (6A, 6B) in the plastic resin.
