METHOD AND APPARATUS FOR SEALING MOTOR TERMINALS

摘要

A wire insulator apparatus includes an insulator/separator member, a cap portion, a tube and potting material. The insulator/separator member has apertures formed therein for receiving a plurality of wires. By threading the wires through the insulator/separator member, the wires are spaced apart so that a potting material can be molded to provide a complete seal from the environment, particularly conductive liquids such as ammonia, which may cause short-circuiting between the wires. Individual wires are terminated in the cap portion, and the cap portion, the insulator/separator member and the wire ends are positioned within a tube or a mold portion depending on the application, and a potting epoxy is fluidly inserted within the tube. The epoxy surrounds or encases the wire ends within the tube or mold to insulate the wire ends in an airtight seal.

1. A sealed wire insulator for sealing motor terminals of a semi-hermetic compressor in an electrically conductive environment, the sealed wire insulator comprising:
an insulator/separator member comprising a plurality of apertures, wherein the plurality of apertures are configured to receive and thread a plurality of wire strands through the insulator/separator member, the plurality of wire strands extends from a motor or compressor housing of the semi-hermetic compressor, the insulator/separator member separates adjacent wire strands of the plurality of wire strands to create a space between the adjacent wire strands; potting epoxy disposed in the space between the adjacent wire strands, wherein the potting epoxy is configured to provide an air tight seal between each of the plurality of wire strands and the adjacent wire strands and from the electrically conductive environment; and a hollow casing surrounding the insulator/separator member, the potting epoxy, and at least a portion of the plurality of wire strands.
