BACKGROUND OF THE INVENTION

Cord grips usually extend around a wire, squeezes down upon that wire, and cause the wire and the surrounding area to be watertight. Cord grips are sometimes known as grommets.

There are several disadvantages to such an arrangement. These grommets or cord grips have to be very large, which makes them very expensive, and they must accommodate not just a wire-width but also a connector-width (if the wire has a connector on the end). Very few users want to remove the connector and then re-attached it once a cord grip is attached.

Consequently, a cord grip must be extra-giant size, and then, one must “rubber up” to make up for that extra size, to get down to the diameter of the cable. This adds to manufacturing costs.

Further, cord-gripping itself the squeezing of the cable is damaging to the cable, both physically and electrically. This is a testable and provable fact. Someone can put a wire on a piece of testing equipment, they can then squeeze the wire, and the instrument will clearly note changes in the electrical properties of the wire.

FIGS. 1A(Prior Art) and1B (Prior Art) show non-limiting examples of cord grips. It is well-established that cord grips are bad for twisted pairs, or any sort of high speed data cabling. Cord grips also can cause reflection, signal degradation, standing waves, adjacent channel interference, and cross-talk, if not outright cable breakage. Cord grips also leak humidity and moisture and heat (both directions), such that a machine-vision camera can be destroyed. It's also time-consuming for a customer to replace a failed cable when it finally succumbs to the forces of the cord grip.

SUMMARY OF THE INVENTION

This disclosure discusses at least two separate embodiments and several sub-embodiments. The first embodiment is an enclosure, such as but not limited to being used for machine-vision cameras, which eliminates cord grips and solves other problems. The second embodiment is an end effector which can be manufactured directly into that enclosure, or be connected therewith.
