[0018] By using the fixing opening and the protective plate in coordination, the wires are inserted into the through holes through the installation opening in sequence until one end of the wires meet at the top of the conductive block. At the same time, it is possible to observe in the fixing opening on one side whether the end of the wire has reached the middle position of the through hole, so that the wiring condition of the wires can be observed more intuitively, thereby improving the practicality of the combined elastic wiring terminal.
