Junction box

摘要

The present invention provides an electrical junction box suitable for connection, for example, to a wire harness in a vehicle such as an automobile. The box is adapted to provide electrical connection to a plurality of electrical connectors, a plurality of fuses and a plurality of relays, the box having a casing (11,12), a connector circuit (13) having a plurality of first bus bars (20), a fuse circuit (14,50) discrete from the connector circuit and having a plurality of second bus bars (20) and a relay circuit (15, 50) discrete from the connector circuit and having a plurality of third bus bars (3). At least one of the second and at least one of the third bus bars are welded to respective ones of the first bus bars at welding portions (16c, 20a; 16e, 20b) which are received in a protection structure (26) which presses them towards each other. The protection structure clamps the joined welding portions so that the risk of disconnection of the welded connection is reduced or avoided.
