Abstract: A spring-loaded contact may include a barrel to form a housing for the spring-loaded contact, a plunger at least partially enclosed by the barrel, a spring enclosed by the barrel, and a sphere between the plunger and the spring. A back of the plunger may be formed at an angle and to include a retention guide, the retention guide partly over the sphere such that the sphere may be in contact with the back of the plunger and the retention guide.

Abstract: A contact terminal having a main body case and a plunger pin received in an elongate hole formed in the main body case is provided. The plunger pin is a round bar provided with a step and includes a small diameter portion including the protrusion end portion and a large diameter portion that slides on a surface of the hole to freely move in a longitudinal direction thereof. A cut space is formed to extend from an end of the large diameter portion so as to leave at least a part of a side surface portion of the large diameter portion and the cut space receives an insulation ball including at least an insulation surface. A coil spring is arranged between the hole and the insulation ball to press the protrusion end portion of the plunger pin such that the protrusion end portion protrudes from the main body case.

Abstract: A contact terminal that enables a relatively large current to flow is provided. A contact terminal (10) includes a main body case (11), and a plunger pin (20) received in a non-penetrating elongate hole (13) formed in the main body case (11). The contact terminal (10) is provided for making electrical connection by contacting the protrusion end portion (21a) of the plunger pin (20) protruding from the main body case (11) with a target part.
