Abstract
A cover and integral straining relief mechanism for an electrical cable multiprong connector, including a two-piece cover utilizing identical and interconnecting halves assembling as a whole connector, mount, and cover. A strain relief mechanism utilizing a cubical insert is included. The cubical insert is a plunger-like mechanism containing teeth-like undulation along its side which interact in a ratcheting fashion with mating undulations within the connector cover. The plunger is inserted into at least one opening in the connector and comes into contact with a cable entering the connector through the remaining and unused opening. The plunger comes into contact with the insulation about said electrical cable such as to hold the cable securely within the connector, thereby providing strain relief action.
