Abstract: A new and improved strain relief for a cord applying a closely controllable force squeezing together a split grommet surrounding the cord. More particularly, a cable tie may be wrapped around the split cylindrical grommet and pulled by a conventional cable tie gun which is set for establishing a predetermined cable tie tension.

Abstract: A wire bundle and grommet assembly includes a grommet body with an extension and a retention sleeve that slideably fits over the grommet body extension. Respective stop flanges are spaced from one another. The retention sleeve also includes a one-way ratchet means, and flexible retention fingers engageable with cam ramps on the grommet body extension. When the wire bundle is pulled through the aperture, the grommet body extension and retention sleeve move as one through the aperture, until the retention sleeve stop flange anchors on the bulkhead panel. Thereafter, the grommet body extension slides through the anchored retention sleeve, and the cam ramps flex the retention fingers outboard, past the perimeter of the aperture, and into engagement with one surface of the bulkhead panel. The grommet body stop flange concurrently engages the other surface of the bulkhead panel. The ratchet means keeps the various parts in that position, and the assembly is thereby attached to the bulkhead panel.

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.

Abstract: An improved molded-in insulated bushing is provided to electrically isolate the mounting fastener used to attach the metallic heat spreader of a semiconductor power device to an external heat sink. The bushing has at one end a flange protruding from one surface of the heat spreader and of sufficient height to exceed the required flash-over voltage. The other end fills a chamfered portion of the heat spreader, and is flush with or relieved from the heat spreader surface which contacts the external heat sink. This shape increases the surface flash-over distance and voltage above that of bushings of the prior art and retains the bushing in the heat spreader. The bushing is advantageously formed during molding of the plastic device encapsulation, but is separated from the encapsulation so that mounting forces are not transmitted through the encapsulation to the semiconductor die and lead wires.
