ABSTRACT:
A connector for connecting a flexible, eccentrically dimensioned conduit to an electrical fixture comprising a connector cap and body portions. The connector cap has a threaded metal collar portion and a plastic floating sleeve with an extending wedging ring. The mating threaded metal connector body has a deflection ramp and an internally secured plastic sleeve support. The connector body is secured to an electrical fixture and the connector cap is loosely threadably engaged with the connector body. The conduit is inserted through an opening in the connector cap until it abuts the bottom of an annular cavity defined between the connector body upper wall and the sleeve support. The cap is then tightly screwed onto the body such that the wedging ring is cammed, by the deflection ramp, into engagement with the conduit to securely grip the conduit. This arrangement provides a liquid-tight seal. The collar and floating sleeve portions of the connector cap may move laterally and pivotably with respect to one another so that the connector may accommodate eccentrically dimensioned conduit and relieve stress imposed by flexing of the conduit during use. Provision is made in the connector design to minimize twisting of the conduit while engaged by the connector assembly. The wedging ring may also be provided with a depending extension ring for gripping the conduit when the connector cap and body are only joined in a finger-tight manner.
