CONNECTION PIN AND ROBOT FOR INSERTING AND DETACHING CONNECTION PIN

PROBLEM TO BE SOLVED: To eliminate the need of installing a sensor for detecting the presence/ absence of the clamping of a connection pin by providing a conductive member for short-circuiting pawl parts in the part in contact with the pawl part of a robot hand of the clamping part of the connection pin. SOLUTION: For a contact plate 4 buried in the clamping part 1b, a metallic plate for instance provided with electric conductivity is buried so as to be exposed from both side faces of recessed parts 3a and 3b to the clamping part 1b between the recessed parts 3a and 3b, contact parts 5a and 5b are constituted at the part exposed from the recessed parts 3a and 3b and they are electrically conducted. Then, after moving the robot hand to a position capable of clamping the desired connection pin 1, the pawl parts 6a and 6b are closed and moved. Thus, the pawl part 6a is fitted to the recessed part 3a of the clamping part 1b of the connection pin 1, the pawl part 6b is fitted to the recessed part 3b and the clamping part 1b is clamped by the pawl parts 6a and 6b. At the time, the pawl part 6a is in contact with the contact part 5a, the pawl part 6b is in contact with the contact part 5b and the pawl parts 6a and 6b are turned to an electrically conductive state by the contact point plate 4.
