Abstract
The coaxial connector includes a plug and a receptacle. The plug contains a spring-loaded central contact and a fixed shield contact. The receptacle contains a fixed central contact and a spring-loaded shield contact. When the plug and the receptacle are joined, each of the spring-loaded contacts is compressed to positively engage the respective fixed contact to facilitate an electrical connection. Mating edges of the plug and receptacle are chamfered to facilitate concentric alignment and to reduce the required insertion force between the plug and receptacle. The contacts of both the plug and the receptacle are recessed below the mating surface to prevent a person or another conductive surface from making inadvertent contact with an electrically conductive member of the connector.
