Abstract: A compressible pin assembly includes a barrel, a contact pin and an elastic element. The contact pin is arranged within the barrel. The contact pin has a contact element. The elastic element is arranged within the barrel to bias the contact pin, so that the contact element is flexibly extended out the front end of the barrel. The barrel has aperture formed therein, which allows superfluous gold plating liquid within the barrel to be eliminated smoothly, after the gold plating process. Thus, the barrel will obtain a more uniform and complete electroplated layer with the use of less gold plating liquid. A stopper will then be inserted into the aperture to prevent impurities from entering the hollow chamber of the barrel. This invention will provide a less expensive compressible pin assembly having greater conductivity.

Abstract: A connector equipped with a terminal protection device including an insulated housing and terminals. The insulated housing includes a plurality of terminal cavities to receive the terminals, and the two ends of the terminals extend beyond the insulating housing. The terminal protection device fixed at the rear portion of the insulated housing has terminal slots characterized by a shape corresponding to the tail portion of the terminal so that the tail portion of the terminal can penetrate the terminal slot and can be locked by the terminal slot. The terminal slot can be either open on both sides or covered by a seal layer. The surface of the terminal protection device facing the rear portion of the insulated housing is provided with fixing protuberances for fixing the terminal protection device to the rear of the insulated housing. In addition, fixing protuberances and a filling protuberance are disposed on the same surface, with a view to fixing and filling, respectively.
