ABSTRACT:
A pin plug comprises an inner contact member in the form of a pin made of metal, an outer contact member in the form of a cylindrical metal body and an insulating member for fixing the inner and outer contact members in position in an electrically insulating manner. Said insulating member comprises an inner insulating member consisting of two semi-cylindrical halves which form in a joined condition a hollow cylindrical space in which said inner contact pin is fit. The insulating member further comprises an outer insulating member or cover made of relatively resilient material. The outer contact member consists of two semi-cylindrical halves which are fixed around the outer surface of the inner insulating member. The assembly of the inner contact pin, the inner insulating member surrounding the pin and the outer contact member surrounding the inner insulating member is resiliently inserted into the space of the outer insulating cover. An electric wire having two conductors is passed through the outer insulating cover and one of the conductors is connected to the inner contact pin and the other conductor is connected to the outer contact member. The pin plug can be easily taken apart by removing the outer insulating cover from the assembly of the inner and outer contact members and the inner insulating member.
