Abstract
ABSTRACT OF THE DISCLOSURE
A circuit board socket is provided with a silicone rubber seal to prevent flux, solder, or other impurities from entering the interior contact areas. Viscous liquid silicone rubber is applied to an opening communicating with the interior of the socket and flows completely into the opening prior to curing to form an effective seal. After the silicone rubber sets, it may be easily pierced by a lead inserted through the opening into the body of the connector for establishing electrical contact with a spring in the interior of the socket,
