In addition, one pogo pin 121 is individually accommodated in the pinhole 311. This prevents the interference between the pogo pins 121 adjacent to each other by the pinhole 311 serves as an insulator.

The stopper surfaces 313 and 314 define a position at which the connection tab part 11 is mounted so that the pogo pin 121 and the connection tab part 11 can be coupled at the correct position. For example, the stopper surfaces 313 and 314 define a seating surface 312 on which the connection tab 11 is seated in the insert portion 131. That is, the stopper surfaces 313 and 314 are formed to protrude a predetermined height on the seating surface 312, and correspond to the width of the portion mounted in the connection tab part 11 to define left and right sides of the connection tab part 11. One on the rear surface (that is, the surface opposite to the direction in which the connection tab portion 11 is inserted) on the seating surface 312 so as to define two left and right sides and the length of the connection tab portion 11 to be mounted.

The insert portion 131 is pressed. As the insert portion 131 moves downward by a force pushed by the pusher portion 133, an end portion of the pogo pin 121 protrudes from the surface of the seating surface 312. Accordingly, the pogo pin 121 and the connection tab part 11 are physically and electrically coupled, and the pusher part 133 may be stably coupled to the pogo pin 121 and the connection tab part 11. The connection tab portion 11 is pressed against the pogo pin 121. The connection tab part 11 and the test object 10 are electrically connected to each other through the main board 20, the connection board 21, and the connection PCB 122 at the pogo pin 121. The main board 20 may inspect whether the inspected object 10 is malfunctioning or defective.
