ABSTRACT:
An electrical connector for connecting liquidtight flexible electrical conduit to an electrical component such as a junction box or outlet, comprises a two-piece, all plastic construction. The connector comprises a plastic body and a plastic gland nut threadably attached thereto. The body includes a plurality of flexible fingers, each of which has thereon a pair of friction-reducing ridges that engage an inner contact surface of the gland nut in tangential, point-contact. As such, upon tightening of the gland nut on the connector body, the gland nut engages the resilient fingers with minimal friction loss, thereby enhancing hand tightening or minimizing the torque required with a tightening tool. In addition, the connector body includes an inner tubular ferrule which defines a conduit supporting surface which includes thereon friction-reducing elements. Such friction-reducing elements permit greater hand insertion and stretching of the conduit onto the connector body to achieve a liquidtight seal between the inner surface of the conduit and the connector body.
