Abstract
Abstract A resilient, curved switch terminal is elastically flexed when deflected by a connector pin inserted into a coaxial connector. The switch terminal is sufficiently long to provide a broad range of resiliency that accommodates plug pins of various dimensional tolerances. The switch terminal contacts a fixed terminal in a normally closed contact position. A connector pin in a mating connector opens the normally closed contact while making a new contact through the connector pin. The terminals are long enough to prevent solder flux from flowing to contacting portions. Solder flux residue is avoided on contacting portions and a more reliable contact is obtained. The portion of the switch terminal that contacts the plug pin is slanted to prevent accumulation of any contaminants such as dust or plating residue that enters the coaxial connector. The slanted contact portion also facilitates assembly of the coaxial connector switch. The resulting coaxial connector is easier to manufacture and has greater reliability while presenting a thin and compact aspect.
