Description

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

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

  As an example, Patent Document 1 (see FIG. 1) discloses that in a connector used in an in-vehicle electronic device or the like, relative movement between a movable housing 8b and a fixed housing 8a having a frame structure surrounding the movable housing 8b is possible. A structure that uses a floating structure to suppress the mounting area of the socket due to this structure is described. By the way, in patent document 1, the board | substrate connection part 13 of the socket terminal 9 fixed to the board | substrate 5 is respectively arranged facing both sides of a pair of side wall surface of a socket.

  As described above, according to the module unit 100 including the socket 1 of the present embodiment, the plug-side case 80 makes the pitch P2 of the lower pitch conversion terminal 82B smaller by dx than the pitch P1 of the upper pitch conversion terminal 82A. Pitch conversion is possible. Thereby, size reduction of the socket 1 to which the lower pitch conversion terminal 82B is connected can be performed. Therefore, the mounting area on the module side substrate 91 on which the socket 1 is mounted can be suppressed, and the module unit 100 can be downsized.

  Further, according to the module unit 100 including the socket 1 of the present embodiment, the plug-side case 80 performs pitch conversion that makes the pitch P1 of the upper pitch conversion terminal 82A larger by dx than the pitch P2 of the lower pitch conversion terminal 82B. It is possible. Thereby, the same socket 1 can be used irrespective of the size (pitch etc.) of the cable side connector 20 to which the upper pitch conversion terminal 82A is connected.
