Circuit Element Retainer

To prevent cable plugs or similar pluggable elements from vibrating loose or being accidentally knocked out of their connectors, an economical and versatile connector retainer has been developed.

As shown, a flat ribbon cable 3 is terminated in a cable plug 5 which has mating electrical contacts in a socket 7, typically an interframe connector. The sockets 7 are nested one atop another as shown, between vertical guides such as 9 and 11, and are provided with horizontally projecting guide elements such as 13, 15 and 17.

Atop each connector block, there are provided a plurality of bosses or projections 19, which space the connector blocks apart by a predetermined distance. The entire assembly is clamped together by clamping means, not shown, which engages the vertical guides 9 and 11 and the topmost block.

The retainers, such as 21, are formed of suitable material, such as plastic, with a thickness equal to or just slightly less than the predetermined distance between the connector blocks. Downward projections such as 23 and 25, spaced apart by the width of the connector block, prevent the retainers 21 from moving out of position when all of the blocks are assembled. By using a forked configuration, retainers 21 can be positioned on opposite sides of the block, as shown.

Each retainer 21 has a downward locking projection 27, spaced so that it abuts the outer end of connector plug 5 when the plug is fully inserted in its socket 7. To remove...
