Abstract
Abstract A high voltage electrical connector wherein the plug and receptacle include rigid dielectric shells. Electrical sockets are retained within rigid dielectric sleeves molded integral with an interior wall of the receptacle. Insulation covered wires are terminated to the socket and are gathered in a bundling ring and then encapsulated. A soft resilient silicone insert is seated in the forward end of the plug and is provided with tapered recesses for matably receiving the rigid dielectric sleeves of the receptacle. Electrically conducting pins are first terminated to insulation covered wires and are then inserted into the rearward portion of the plug until the pins project into the tapered recesses of the insert. In one version the rearward portion of the plug is then filled with an encapsulant material sealably encircling the insulation covered wires. In another version the silicone insert is provided with elongated tubular extensions which project through apertures in a solid plug end. The tubular sections thus compressibly encircle the corresponding insulation covered wires. The connector is further provided with polarizing features and a threaded coupling to retain the plug and receptacle in mated relationship.
