Liquid-tight, strain-relief connector for connecting conduit and the like

Abstract

There is provided a strain-relief, liquid tight for connecting conduit or the like to a bulkhead such as an electrical box, with the connector having a body having front and rear portions, and a substantially hollow inner throughbore formed along a longitudinal axis thereof. The front portion of the connector body is adapted for attachment to a bulkhead. A flexible seal member is mounted at least partially within the hollow inner throughbore for receiving a conduit inserted therethrough, this seal member facilitating a substantially liquid tight seal about an inserted conduit during use. An at least partially hollow grip for selectively gripping the conduit is included, and a clamp nut is telescoped over the rear portion of the body for selective longitudinal adjustment therealong. The longitudinal adjustment of this clamp nut provides inward radial compression of the flexible grip about the conduit. In a preferred embodiment of the present invention, the grip member comprises a plurality of gripping fingers cantilevered from a ring-like base portion, and the seal member is at least partially disposed within the grip member. A cam surface is provided in the interior of the body, and a compression member on the clamp nut urges the gripping fingers against this cam surface thereby causing the fingers to be compressed radially inward. This results in the conduit being gripped and also enhances the sealing of the seal member about the conduit.
