ABSTRACT:
The electric junction box of this invention has a plurality of connector receiving sockets mounted on its insulating box. Selected one of the connector receiving sockets, or the first connector receiving socket, is attached with a locking cover, which is urged by a spring to lie flat over the adjacent or second connector receiving socket. A first connector can be assembled onto the first socket but a second connector cannot be connected to the second socket unless the locking cover is erected and locked onto the first connector. To rule out the slightest possibility of erroneous connection sequence, a connection sequence check member is provided to the second connector. Should the second connector be assembled onto the mating socket first, prior to the first connector, by erecting the locking cover, the connection sequence check member abuts against the back of the locking cover to cause the locking cover to advance in the way of the first connector, so that the first connector is blocked and cannot be assembled onto the associated socket, alerting the assembly worker to the wrong sequence of the connector assembly.
