In an embodiment, a socket comprises a housing, where the housing is a dielectric material. In an embodiment, a shell passes through a thickness of the, where the shell is conductive. The socket may further comprise a plug within the shell, where the plug is a dielectric material, and where the plug has a bottom surface. In an embodiment, a pin passes through the thickness of the housing within an inner diameter of the shell, where the pin has a first portion with a first diameter and a second portion with a second diameter, and where the pin is conductive. In an embodiment, the socket further comprises a spring around the first portion of the pin, where a first end of the spring presses against the bottom surface, and where a second end of the spring presses against the second portion of the pin.

A towing electrical connection, for at least four different wires, is made by face contact elements exposed on one side of a housing, such as in an adapter piece having a standard configuration of prongs/sockets on a back side. The adapter piece can be plugged onto the standard electrical plug of a towing vehicle or trailer a single time, leaving the face contact elements exposed for repeated connection and disconnection each time the trailer is connected or disconnected from the towing vehicle. A magnetic attraction force is used to pull and hold the face contact elements in electrical connection, such as by magnets insert molded into a housing of the adapter piece(s) immediately adjacent the exposed face contact elements. A short twisting rotation of the adapter piece about a longitudinal axis is preferably used during connection and disconnection.

A connector housing includes a body defining an accommodating channel sized to receive a pin terminal, and a blocking structure formed in the accommodating channel and positioned to prevent a bent portion of a pin terminal from rebounding.
