  As shown in FIGS. 5 and 6A, the pin member 241 is fixed to the distal end of the locking wall A inside the slot 222a in a state where the core unit 22 and the connector 221a are housed in the housing space 212. Yes. At this time, as shown in FIG. 5 and FIG. 6B, the user turns the rotating rod body 24 and rotates the rotating rod body 24 in the pushing direction, whereby the pin member 241 pushes the guide wall B into the guide wall B. The core unit 22 is moved toward the opening 211, and the connector 221 a is pushed out of the housing 21. At this time, a force is applied to the elastic member 23 by the core unit 22, and the elastic member 23 is compressed by the received force and accumulates a biasing force.

  As shown in FIGS. 5 and 6C, when the pin member 241 is moved to the locking wall A, the pin member 241 is locked by the locking wall A. Therefore, the rotating rod body 24 can be turned in the retracting direction. Can not. At this time, the connector 221a is completely exposed to the outside of the housing 21. At this time, as shown in FIGS. 5 and 6D, the pin member 241 is locked by the locking wall A and fixed to one end of the slot 222a. Therefore, it becomes impossible to rotate the rotating rod 24 in the retracting direction. The pin member 241 can apply a force while stably contacting the end of the core unit 22 on the rear side. Therefore, in the process of inserting the connector unit 2 into the socket J, the core unit 22 cannot move to the rear end of the housing 21 due to the reaction force received by the connector 221a. Therefore, the user can quickly push out the connector 221a to the outside of the housing 21 by slightly turning the rotating rod 24 without applying force to the connector unit 2, and the connector 221a is extended to the outside of the housing 21. It can be firmly fixed to the state. The user can perform data transmission between the connector unit 2 and the electronic device by connecting the connector unit 2 to the socket J of the electronic device.

  A spring plate (not shown) is attached inside the socket J of the connector unit. The connector 221a inserted into the socket J can be pressed by the spring plate, and the connection reliability between the connection terminals can be improved. Therefore, when the user removes the connector unit 2 from the socket J, if the housing 21 is pulled, the connector 221a is pressed against the spring plate inside the socket J, so the housing 21 While moving to the rear end, the housing 21 drives the rotating rod 24 and unlocks the state where the pin member 241 contacts the locking wall A. Then, the pin member 241 is moved along the restoring wall C to a place past the corresponding connecting portion between the locking wall A and the guide wall B.

  As shown in FIGS. 5 and 7B, when the connector 221a is pulled out from the socket J, the locking force of the pin member 241 to the locking wall A is released, so that the core unit 22 is automatically driven by the biasing force of the elastic member 23. Accordingly, the pin 21 moves to the rear end portion of the housing 21 to bring the pin member 241 into contact with the guide wall B. At this time, as shown in FIG. 5 and FIG. 7C, the pin member 241 cannot receive the locking of the locking wall A. Therefore, the pin member 241 is pushed along the guide wall B by pushing the rear end of the core unit 22. While moving to one end of the locking wall A inside the slot 222a, the rotating rod 24 is driven to rotate in the retracting direction.

  As shown in FIGS. 5 and 7D, when the core unit 22 and the connector 221a are completely drawn into the housing 21, the pin member 241 is again fixed to the far end of the locking wall A inside the slot 222a. The In the present specification, the description relating to the connection between the locking wall A, the guide wall B, and the return wall C will be described in which the pin member 241 is along one of the lock wall A, the guide wall B, or the return wall C. The pin member 241 is guided to one end of the other when it moves to either one end. As an example, in the first embodiment, one end of the guide wall B and one end of the locking wall A are directly connected. Further, the other end of the locking wall A and one end of the restoring wall C are directly connected. Further, the other end of the return wall C and the other end of the guide wall B are not directly connected. However, after the pin member 241 moves from one end to the other end of the return wall C, it is detached from the locking wall A and guided. Guided by wall B. Therefore, here, the term "connected" or "connected" is not only the relationship that the two are physically "directly connected", but also "indirectly connected" via another member between the two "Also means the relationship.

  As shown in FIG. 7A, in this embodiment, the user can fix the connector 221a to a state where the connector 221a is completely exposed to the outside of the housing 21 by slightly turning the rotating rod body 24. The connector unit 2 can be inserted into the socket J and the terminals can be connected to each other without applying a force to the socket. On the other hand, since force is applied to the connector 221a from the socket J, when the connector unit 2 is pulled out from the socket J, the pin member 241 is released from the state of being locked to the locking wall A (shown in FIG. 5). . At this time, the elastic member 23 pushes in the core unit 22, and the connector 221a is automatically drawn into the housing 21, so that the convenience of use can be greatly improved.

  The operational relationship between the elements in the third embodiment of the present invention will be described.

When the user pushes the pushing member 45 from the outside of the housing 41, the core unit 42 is pushed, and the connector 421a is exposed to the outside of the housing 41 from the opening 411 on the front side of the housing 41. At this time, the pin member 441 moves along the guide wall B1 while pushing the guide wall B1. The bottom surface of the slot 422a corresponding to the guide wall B1 forms a slope, and when the pin member 441 moves, it is moved along the slope from one end to the other end of the guide wall B1.

  As shown in FIGS. 10 and 12, when the connector 421a is completely pushed out to the outside of the housing 41, the pin member 441 moves to the end connecting the guide wall B1 and the locking wall A1, and this position The vehicle moves over the height difference and is moved to the locking wall A1. The pin member 441 is locked by the step and cannot return to the slope corresponding to the guide wall B1. Further, the pin member 441 is locked by the locking wall A1, and the acting force applied to the core unit 42 by the elastic member 43 inside the connector unit 4 causes the core unit 42 to move to the rear end of the housing 41. The connector 421a is kept exposed to the outside of the housing 41. As shown in FIGS. 11 and 12, when the user pulls out the connector unit 4 from the socket J, the housing 41 moves to the rear end of the core unit 42 with respect to the core unit 42. The housing 41 drives the rotary rod 44, and the pin member 441 moves along the locking wall A1 to the end where the locking wall A1 and the restoring wall C1 are connected, and gets over the slope corresponding to the restoring wall C1. When the connector 421a is pulled out from the socket J, the pin member 441 moves along the backward wall C1 to the end connecting the backward wall C1 and the guide wall B1, passes over the step, and returns to the slope corresponding to the guide wall B1.
