Strain Relief Device

The device retains cables or rods in place in a housing and is resistant to axial displacement.

Three parts are assembled around a rod and inside a housing. These are a rubber spring, a locking ring and a knob with a face cam pressing against the ring. The face cam cants the locking ring at the same angle as the shape of the rubber spring. The edges of the bore of the locking ring bite into the rod and prevent its axial movement. By twisting the knob 180 degrees, the face cam is turned so that its high edge compresses the high wall of the rubber spring. Between them, the locking ring assumes a position normal with respect to the rod in which the ring bore is concentric with the rod and large enough to allow free axial movement of the rod. If the knob is turned another 180 degrees, the rubber spring again cants the locking ring and grips the rod or cable to lock it to the housing.

The locking action results from a short rotary or twisting adjustment. This makes the lock adaptable for situations where the usual linear control is too time consuming or requires too much space. In eliminating notches and preset detents, this device has great flexibility. In instances where it is desirable to change to cables or rods of differing diameters, it is simple to change the locking ring for one with a suitable bore.
