Abstract

An electrical junction device including an electrical insulating housing having a plurality of terminal receiving chambers partitioned by a plurality of first partition walls. The device also includes a joint terminal member having a common base, a plurality of terminals adapted to be connected to mating terminals and extending from the common base, and a connecting portion formed in the common base and adapted to be connected to an external wire. The terminals of the joint terminal member are received in the terminal receiving chambers of the housing, respectively. A connecting portion receiving chamber having an opening is formed in the housing so as to be partitioned from the terminal receiving chambers by a second partition wall. A plurality of slits are formed in the partition walls for permitting insertion of the joint terminal member. A common base receiving portion is formed in each of the terminal receiving chambers so as to be communicated with the slits. The common base receiving portion has a bottom wall adapted to abut against the common base upon insertion of the joint terminal member into the slits. The connecting portion is formed by bending the common base to be exposed to the opening of the connecting portion receiving chamber. This structure allows the connection between the joint terminal member and the external wire to be carried out irrespective of the timing of mounting the electrical junction device to a vehicle, the joint terminal member is prevented from being detached from the housing upon insertion of the mating terminals, and, the structure of the device is simplified.
