To perform the high density packaging of a matrix board and to simplify a robot by turning the shape of the clamping part of a connection pin to a quadrilateral box shape.
This connection pin 1 is constituted of a shaft part 1a to be inserted to the pin hole of the matrix board and the clamping part 1b to be clamped by a robot hand. In this case, the clamping part 1b is provided with the quadrilateral box shape provided with the cross-sectional shape of a thin and long rectangle viewing from an upper part and is turned to the shape for which recessed parts are provided symmetrically on opposing two side faces. The robot hand of the robot for handling the connection pin 1 is constituted of two pawl parts 3 made to face each other and opening/closing operations are performed by a prescribed mechanism. At the time, the contact surfaces of the pawl parts 3 and the clamping part 1b are mutually turned to planes and surface contact is made possible. Thus, the clamping mechanism of two fingers is used and clamping is performed even when the center of the connection pin 1 is shifted to the pawl parts 3.
