Abstract

An elastic-clip junction box structure has multidirectional wire insertion effect and holds the wires quickly. The junction box structure includes a case body and at least one conductive clip disposed in the case body. The case body is formed with a first-direction wire socket and a second-direction wire socket with different insertion directions. The conductive clip has a first-direction clip mouth in communication with the first-direction wire socket and a second-direction clip mouth in communication with the second-direction wire socket. In use, the wire can be selectively inserted into the first-direction wire socket or the second-direction wire socket. Alternatively, wires can be respectively inserted into both the first-direction wire socket and second-direction wire socket. Accordingly, wires can be selectively inserted into the elastic-clip junction box structure in multiple directions and quickly and securely held by the first-direction clip mouth and second-direction clip mouth or released therefrom.
