Here, the diameter of the opening 123c having an inclined surface may be larger than the opening 113c formed at the lower end of the signal pin 113 of the connector 110.

This is because the upper body 111 and the lower body 115 of the connector 110 may be already assembled before actual operation but the coupling of the connector 110 and the receptacle 120 is performed in the field in actual operation So as to facilitate the coupling in the operation.
