Abstract
A process for preparing an electrical connector from a glass plug, a rigid metal shell, and at least one pin conductor is disclosed. The glass plug is made by mixing glass powder with binder, forming a green body, debindering the green body, and heating the debindered green body. The metal shell and metal pin conductor(s) are first cleaned by heating them in a hydrogen-containing atmosphere, and thereafter forming an oxide coating on their surfaces. An assembly is then formed from the rigid metal shell, the glass plug, and the pin conductor(s). This assembly is then heat treated to form the electrical connector.
