Abstract

There is provided an improved high voltage cable coupler having a body of integrally cast dielectric polymer chemically formed in situ and having at least one cable receiving channel therethrough. An internal conductor is cast within the body extending within the cable receiving channel to receive the end of a cable. The cable receiving channel is symmetrical, and a cable may be inserted in one end, secured through the other, and the other end then plugged. A soft polymer sealing sleeve advantageously provides air-free interfaces between the cable and the walls of the cable channel, and between the plug and the wall of the cable channel. In a desired embodiment, the soft polymer sealing sleeve is thicker in wall section than the space between the cable and channel so as to form an interference fit between the cable and channel, and between the plug and cable channel wall, so as to resiliently load the soft polymer. At all times, the inner end of the soft polymer is free to move axially into a shielded space, thus permitting a limited range of cable diameters to be used with a given sealing sleeve, and a wide range of cable diameters can be accommodated by employing sealing sleeves of various appropriate wall thickness.

Claims

2. A device as recited in claim 1 wherein said second and third means comprise soft dielectric sealing sleeves elongated axially and circumferentially distorted and stressed upon the receipt of said insulated portion of said cable and said dielectric means, respectively, to maintain said insulated portion of said cable and said dielectric means in said void-free interfacial relationships within said channel.

3. A device as recited in claim 1 wherein said dielectric means comprises a dielectric plug having a longitudinally extending air vent and means for sealing said air vent.

4. A device as recited in claim 1 further comprising conductive means affixed to a portion of that part of said body forming said channel, conductively connected to said first means for reducing the electrical stress on the air trapped within said channel.

5. A device for terminating the end of a high voltage cable comprising a body of dielectric material, a channel extending through at least a portion of said body, means within said channel receiving and maintaining in a void-free interfacial relationship an insulated portion of said cable, said means comprising a soft dielectric sealing sleeve elongated axially and circumferentially distorted and stressed upon the receipt of said insulated portion of said cable to maintain said insulated portion of said cable in said void-free interfacial relationship within said channel, and means holding one end of said sleeve in place within said channel.
