Description

The present invention relates to a socket having a floating structure and a module unit including the socket.

Module units such as in-vehicle cameras and surveillance cameras are provided with sockets mounted on the board of the module unit. The socket is provided with a slot for fixing the contact terminal inside, and the plug is detachably and electrically connected via the slot. This socket often has a floating structure in order to allow mounting errors between the plug and the socket and to suppress the influence of vehicle vibration and the like.

As an example, Patent Document 1 (see FIG. 1) enables relative movement between the movable housing 8b and the fixed housing 8a, which is a frame structure surrounding the movable housing 8b, in a connector used for an in-vehicle electronic device or the like. In addition to using a floating structure, a structure that suppresses the mounting area of the socket due to this structure is described. By the way, in Patent Document 1, the substrate connection portions 13 of the socket terminals 9 fixed to the substrate 5 are arranged so as to face both sides of the pair of side wall surfaces of the socket.
