<p>PURPOSE:To provide a fixing structure for an electric joint box and a relay unit for optional circuit wherein the number of components such as wires and connectors and the manpower for jointing work can be reduced. CONSTITUTION:An electric joint box A comprises cases 1, 1' for containing circuit boards, connectors 2A, 2B... for connecting electric components and wire harness to the outer faces of the cases 1, 1', and a spare connector 10 for distributing power supply. A bus bar having a terminal connecting part to be connected with a connector terminal 12 of the spare connector 10 at one end and a power supply terminal connecting part to be connected with the power supply terminal of a relay 4 at the other end is interposed between a JB coupling connector B2 and a relay mounting part B1 of a relay unit B. Lock means 13, 21 are further interposed between the spare connector 10 and the JB coupling connector B2 so that electrical and mechanical coupling are established simultaneously between the electric joint box A and the relay unit B upon locking of the connectors B2 and 10.</p> |
