ABSTRACT:
A four-piece all plastic strain relief connector for connecting an electrical cord to an electrical fixture comprising a body member and cap member which threadably engage to form a chamber. Located within this chamber is a collet and diaphragm assembly consisting of a flexible diaphragm snap-fit to a semi-rigid collet. The diaphragm has an aperture through which the cord passes and which forms a liquid-tight seal with the cord. The collet has a plurality of deformable tines for gripping the cord. One end of the body member is attached to a through hole in the electrical fixture. After the cord is inserted through the connector, the cap and body members are tightly screwed together such that a protrusion on the body deforms the tines on the collet into engagement with the cord. Teeth on the tines engage the plastic jacket of the cord to provide a secure grip. A sealing member formed on the collet makes a liquid-tight seal with the body member and resists the force required to insert the cord through the aperture of the diaphragm, thus the tines are prevented from being prematurely deformed by the protrusion.
