ABSTRACT:
An improved cord grip and strain relief fitting to restrain and seal flexible cord to an enclosure or junction box. The structure includes a body member, a grommet, a strain relief member and a nut. Tightening the nut onto the body member results in radial forces between the grommet and the cord to restrain the cord and provide a water tight seal. The grommet is stuffed into the body member by an interaction between the grommet and the strain relief member as the nut is engaged with the body member. The lower end of the strain relief member has legs which mate with sockets in the grommet and which receive a radial inward force during final assembly causing the legs to pivot inward and apply an additional retaining and restraining force on the cord. The strain relief member has an upper portion which flares away from the cord thereby providing an increased radius of curvature if the cord is deflected from its longitudinal direction at the external end of the fitting.
