Abstract

The device comprises a clamping member formed by an annular collar of plastic material which is intended to rest on a bearing surface of the handle with interposition of a shouldered tubular seal in intimate contact with the cable. Jaws integral with the collar and extending vertically upwards therefrom in radial planes cooperate with an internal frusto-conical bearing surface of the connector cap. When the cap is screwed-down onto the handle, the jaws produce a powerful clamping action on the cable.

Claims

1. A device for fastening a cable to a connector handle including an annular shoulder, the device essentially comprising a connector cap and a clamping member formed, on the one hand, by an annular collar of plastic material which is intended to rest on a bearing surface of the handle with interposition of a shouldered tubular seal closely applied against the periphery of said cable and, on the other hand, by a plurality of jaws forming one piece with said annular collar and extending vertically upwards therefrom in radial planes, said tubular seal including a terminal annular trough within which said collar is inserted thereby maintaining said tubular seal tightly applied against said annular shoulder, and said jaws being adapted to cooperate with an internal frusto-conical bearing surface provided in the connector cap in such a manner as to ensure that said jaws produce a powerful clamping action on the cable at the time of fixing said cap on said handle.

2. A cable-fastening device according to claim 1, wherein the jaws are divergent from the annular collar and have a cross-section at right angles to the axis which is initially relatively small at the roots of said jaws and progressively increases to the vicinity of the upper extremities thereof.

3. A cable-fastening device according to claim 1, wherein the tubular seal has the shape of a cone frustum provided with an annular flange on the large base thereof.

4. A device for fastening a cable to a connector handle, essentially comprising a connector cap, and a clamping member formed, on the one hand, by an annular collar of plastic material which is intended to rest on a bearing surface of the handle with interposition of a shouldered tubular seal closely applied against the periphery of said cable and, on the other hand, by a plurality of jaws forming one piece with said annular collar and extending vertically upwards therefrom in radial planes and adapted to cooperate with an internal frusto-conical bearing surface provided in the connector cap in such a manner as to ensure that said jaws produce a powerful clamping action on the cable at the time of fixing said cap on said handle, said seal being constituted by an internal annular flange of the clamping member which is of progressively decreasing thickness in the direction of the axis and through which the cable is passed as a result of elastic deformation of said flange.
