  The present invention relates to a plug, a socket, and a board connecting connector including them.

  In an electronic device, for example, a plurality of printed circuit boards arranged to face each other are incorporated in a relatively narrow space. Such a plurality of printed circuit boards are electrically connected to each other through, for example, a board connecting connector as disclosed in Patent Document 1.

  Such a board connecting connector includes, for example, a socket arranged on the first printed wiring board, and a plug arranged on the second printed wiring board arranged opposite to the first printed wiring board. It is comprised including.

  For example, as shown in Patent Document 1, the socket includes a floating mechanism so as to absorb an error in a relative position with respect to a plug to be connected. Such a floating mechanism is configured to movably support the power supply terminal block with respect to the common housing so that the plurality of signal terminals and the power supply terminal bridge the power supply terminal block and the common housing at both ends, respectively. ing. Between the power supply terminal block and the signal terminal block in the socket, an interval for inserting the above-described plug partition is formed.

  In the configuration in which two power supply terminal blocks in a board connecting connector having a floating mechanism as shown in Patent Document 1 are connected by a common housing, the occupied area of the board connecting connector is relatively small in the printed wiring board. As the size increases, cracks may occur in the joining of the soldering terminal portions of the board connection connector due to the difference between the linear expansion coefficient of the printed wiring board and the outer portion of the board connection connector.
