Abstract

The invention discloses an optical cable clamp which comprises a main body, a front clamping part and a rear clamping part, wherein the main body is provided with a front main body part and a rear main body part; the front clamping part is used for clamping a strengthening element of an optical cable; and the rear clamping part is used for clamping an outer cladding layer of the optical cable. The front clamping part comprises a wedge-shaped slot formed in the front main body part and a wedge-shaped block accommodated in the wedge-shaped slot. A gap between the inner side wall of the wedge-shaped slot and the outer side wall of the wedge-shaped block is formed in a way of becoming gradually narrower from the bottom of the wedge-shaped slot. The strengthening element of the optical cable passes through the gap between the outer wall of the wedge-shaped block and the inner wall of the wedge-shaped slot and is clamped between the outer side wall of the wedge-shaped block and the inner side wall of the wedge-shaped slot. In the optical cable clamp, the strengthening element is firmly self-locked between the outer side wall of the wedge-shaped block and the inner side wall of the wedge-shaped slot through a frictional engaging force between the strengthening element and the outer side wall of the wedge-shaped block and a frictional engaging force between the strengthening element and the inner side wall of the wedge-shaped slot, thereby being capable of effectively preventing the optical cable from moving relative to the optical cable clamp under the action of a larger external pulling force.
