In the maintenance work or expansion work, connection or disconnection is performed by inserting / removing a connector provided in the central processing unit. Disconnected.

  Specifically, as shown in FIGS. 4A to 4C, the power supply pin 2 and the signal pin 3 which are contact pins are arranged on the backboard 1, and the power supply pin 2 and the signal pin 3 are fitted. A power socket 4 and a signal socket 5 as contact sockets are attached to the card 6. Therefore, the power pin 2 and the power socket 4, the signal pin 3 and the signal socket 5 constitute a connector, respectively.

  When the card is exchanged while the central processing unit in the computer system is operating, the card is connected to the power supply pin 2 and the signal pin 3 of the back board 1 of the central processing unit as shown in FIGS. 4 (A) and 4 (B). When the power socket 4 and the signal socket 5 are inserted, it is necessary to determine the order in which the power pins 2 and the signal pins 3 are brought into contact with the card 6.

  Usually, by changing the protruding length of the power supply pin 2 and the signal pin 3, that is, in the case of FIG. 4, the protruding length of the power supply pin 2 is made longer than that of the signal pin 3. After the long power pin 2 contacts first, the short signal pin 3 contacts thereafter.

  However, the outer shape of the entire connector is increased because the long power supply pin 2 is inserted into the short power supply socket 4, and when the power supply pin 2 is inserted into the power supply socket 4, the tip of the power supply pin 2 is the power supply. Since it protrudes from the socket 4, the component mounting area is narrowed by the protruding portion, and as a result, there is a problem that the entire card 6 is also enlarged.

Conventionally, there is an invention disclosed in Patent Document 1 in consideration of such circumstances. The present invention provides a rotation guide means for displacing the pin in the axial direction according to the axial slide of the pin when pressing the contact end of the pin held in the housing portion of the connector case against the contact member, For this reason, when the pin slides in the axial direction, the pin is displaced in the direction around the axis by the rotation guide means, and the contact end rotates and contacts the contact member.
