Cable Retainer

An electrical cable subject to strain can be effectively maintained in a machine wall and provided with a degree of relief by using a self-locking plastic retainer.

Electrical cables are normally frictionally held in machine walls by pliable grommets having inside diameters slightly smaller than the diameters of the cables. Humidity, contamination, degradation, and excessive forces have contributed to cables being dislodged, and presenting a serious electrical hazard.

The cable retainer shown in Fig. 1 has collar 2 for fitting within a cable opening in the housing wall. Shoulder 1 will be interior of the housing and has lugs 3. The ends of lugs 3 projecting toward the center of the retainer are spaced less than the diameter of the cable.

When a cable 4 has been inserted from the left into the housing as shown in Fig. 2, lugs 3 will be forced apart. Insertion of the cable requires little force and no special tools for expansion of lugs 3. Thereafter, if a leftward force is applied to the cable, lugs 3 will act to lock and hold the cable in place. Also, for greater than normal forces, lugs 3 will deform and provide a degree of relief.
