Abstract: A liquid tight connector for pass through cable, tubing or rods includes a body, a compression nut and a gland. There are fingers on the body with flats and triangular ends which cradle the gland and grasp cable, tubing or rods in a liquid tight manner tightly enough to provide strain relief. Spherical bumps with pawl like flats hold the compression nut free of the likelihood of loosening once engaged. The triangular configuration of the ends of the fingers enables improved strain relief and adapts to a large selection of cable, tubing or rod diameters.

Abstract: A fitting or connecting corrugated tubing has a through opening and a liquid tight corrugated tubing connecting portion. The connecting portion has a shank to receive the corrugated tubing and a collar of greater diameter than the shank. The collar extends along the shank from a shoulder in the fitting and terminates before the end of the shank. Pawls in the connecting portion extend from the shank between the collar and the end of the shank. The pawls are hinged and have bevels and a bearing surface. The collar on the shank has an outside diameter slightly greater than the inside diameter of the corrugated tubing which renders the connector liquid tight when engaged with the corrugated tubing. The pawls resiliently extend to engage themselves in an inner corrugation of the corrugated tubing. Various pawl configurations engage the inside corrugations of corrugated tubing for a quick and firm liquid tight connection.

Abstract: A molded plastic strain relief bushing and method includes a body with a channel. A hinged head on the body has one portion contiguous with the channel. There is a well and key receiver at the well. Wire or cable is laid in the channel, locked into the channel in strain relief engagement. The head is then folded over the wire or cable and the strain relief bushing engaged in an aperture. The function of holding the wire or cable is separate from the function of engaging the strain relief bushing. The split head enables the functions to be separate and yet permit the laying in of the wire or cable without the awkward need to thread the wire or cable through a fixed opening in the strain relief bushing.

Abstract: A screw with an unthreaded spaced away radial flange portion on its shank may be tightened and released within a bore without falling from the bore once released. The assembly of the screw and a strain relief bushing permits the conventional strain relief bushing to optionally hold and release cable without risking the loss of the retaining screw from the bushing.

Abstract: A one piece molded plastic strain relief bushing includes a well and key. The portions of the bushing may be engaged, latched in the well. The latching within the well serves the double function of holding the bushing with a cable engaged and compactly providing such holding with a maximum of strength and a minimum of bulk. The bushing enables saving of cost in the insertion of the cable into the bushing and saving cost, inserting the bushing with the cable into an aperture.

Abstract: A liquid tight connector accepts a non-metallic conduit grasped by fingers on a clip grasping above an annular ring on a ferrule. A compression nut engages the fingers. The configuration enables labor saving insertion and effective liquid tight integrity in an inexpensive device.
