Abstract

A strain relief shell is provided for relieving stress between an electrical connector and an electrical cable. The shell includes a pair of complementarily interengageable shell halves defining an interior cavity. The shell halves are releaseably engageable with the electrical connector on a given center line. A pair of cable exit openings are provided through the shell at different orientations such that the cable can exit from one opening in a direction generally parallel to the center line and from the other opening in one of two directions generally transverse to the center line. A pair of holding loops are formed integral with the shell, projecting into the interior cavity thereof, for holding a cable tie about the cable respectively in either of the directions thereof. Break-away plug portions are formed integrally with the respective shell halves for closing the cable exit openings. One or both of the plug portions in each opening is removable so that less than the entire respective cable exit opening can be exposed to accommodate different sized cables.

Claims

1. In a strain relief shell for relieving stress between an electrical connector and an electrical cable, including a pair of complementarily interengageable shell halves each having a generally flat body wall and end walls defining an interior cavity where the flat body walls are parallel to each other and the end walls of one shell half abut the end walls of the other shell half, means operatively associated between the shell halves releaseably engaging the electrical connector on a given center line, wherein the improvement comprises a pair of cable exit openings through the shell at different orientations in the end walls such that the cable can exit from one opening in a direction generally parallel to said center line and from the other opening in one of two directions generally transverse to the center line, and holding means integral with the generally flat body wall of each shell half accessible from the interior cavity for holding a cable tie about the cable within said interior cavity respectively in one of any of said directions.

2. In a strain relief shell as set forth in claim 1, wherein each of said shell halves is unitarily molded of dielectric material such as plastic, and said holding means is molded integrally with each shell half on the interior thereof.

3. In a strain relief shell as set forth in claim 1, wherein each of said shell halves is unitarily molded of dielectric material such as plastic, and including break-away plug means for removably closing said cable exit openings, the plug means being molded integrally with at least one of the shell halves.

4. In a strain relief shell as set forth in claim 3, including weakened material about the periphery of said plug means to facilitate breaking the plug means away from the at least one shell half.

5. In a strain relief shell as set forth in claim 3, wherein said break-away plug means for each opening include a first plug portion molded integrally with one of the shell halves and a second plug portion molded integrally with the other shell half, whereby less than the entire respective cable exit opening can be exposed to accommodate different sized cables.

6. In a strain relief shell as set forth in claim 5, wherein said cable exit openings and said plug means are generally circular, and said plug portions are generally semi-circular.

7. In a strain relief shell as set forth in claim 1, wherein each of said shell halves is unitarily molded of dielectric material such as plastic, and said holding means comprise loops molded integrally with the shell halves and projecting into the interior thereof.
