Abstract
An insulating holder has a first face and a second face, with a first hole that has a first diameter at the first face, and a second hole that has a second diameter larger than the first diameter and extended from the second face so as to communicate with the first hole. Inside the second hole is a plate-shaped conductive terminal that has a base portion and at least one pair of guide portions extended from the base portion so as to define a concave portion between opposed inner edges of the guide portions. The concave portion faces the first hole. Included in between the opposed inner edges of the guide portions is a conductive pin with a plunger portion that has a diameter smaller than the first diameter and a bulged portion that has a diameter larger than the first diameter. The bulged portion of the pin has opposed grooves at its periphery that run parallel to the plunger portion's longitudinal axis and is fitted with the guide portions so as to be slidable along the concave portion. A spring member is also provided in the concave portion so as to urge the pin toward the first face of the holder, so that the plunger portion of the pin is retractably protruded from the first face of the holder through the first hole.
