Device for clamping the cable in electrical outlets or plugs
First Claim
1. A device for clamping a cable in an electrical outlet or plug, the device comprising:
- a body that encloses a connecting jack that can be connected to the cable to be clamped;
a threaded locking nut;
a grip element which is arranged in said body between said body and said threaded locking nut on an inlet side of the cable, said gripping element including a plurality of flexible jaws;
a conical connection joining said grip element to said body, said grip element being tightened around said cable to be clamped after said locking nut is screwed onto said body, wherein said grip element is provided with two tongues, which are parallel to said jaws and are intended to be inserted and to slide in corresponding indentations on an outside of said body, and in which said tongues have lateral locking teeth, which are intended to intercept opposing teeth on sides of said indentations in order to prevent the detachment of said grip element when said grip element is stopped in relation to said body, said conical connection including a substantially conical seat formed of grooves which are intended to accommodate said flexible jaws of said grip element and to prevent rotation of said grip element with said locking nut.

Abstract
An electrical outlet or plug includes a body, which encloses a connecting jack, which can be connected to a cable, and a grip element for clamping the cable. The body and grip element are provided with complementary features, which limit the axial unthreading movement of the latter in relation to the former and for preventing their disconnection once they have been connected. A locking nut is joined to the grip element axially, with the possibility of remaining joined to the said grip element, and through this, to the body when the nut is completely unscrewed and removed. Structure is also provided for preventing the unscrewing rotation of the nut once it has been screwed down.

14. A device for clamping a cable in an electrical outlet or plug, the device comprising:
-
a body that encloses a connecting jack that can be connected to the cable to be clamped; a threaded locking nut; a grip element which is arranged in said body between said body and said threaded locking nut on an inlet side of the cable; a conical connection joining said grip element to said body, said grip element being tightened around said cable to be clamped after said locking nut is screwed onto said body; said body and said grip element are provided with complementary limiting means to limit axial movement of said body and said grip element and to prevent disconnection of said body and said grip element once they have been connected and said locking nut is unscrewed from said body; said locking nut and said grip element are joined axially with the possibility for said nut to rotate in relation to said grip element, but to remain joined to said grip element and, through this, to said body when said nut is completely unscrewed and removed; and said locking nut and said grip element include means which interact to make possible a unidirectional rotation for screwing and to prevent the opposite rotation for unscrewing when said nut is screwed onto said body for clamping said cable with said grip element, wherein said grip element is provided with two tongues, which are parallel to a plurality of flexible jaws and are intended to be inserted and to slide in corresponding indentations on an outside of said body, and in which said tongues have lateral locking teeth, which are intended to intercept opposing teeth on sides of said indentations in order to prevent the detachment of said grip element when said grip element is stopped in relation to said body. - View Dependent Claims (15, 16, 17)

18. A device for clamping a cable in an electrical outlet or plug, the device comprising:
-
a body that encloses a connecting jack that can be connected to the cable to be clamped; a threaded locking nut; a grip element which is arranged in said body between said body and said threaded locking nut on an inlet side of the cable; a conical connection joining said grip element to said body, said grip element being tightened around said cable to be clamped after said locking nut is screwed onto said body; a seal placed in said body, said seal including a part that is made in one piece with said body proper and acts around the cable, adapting to the cable without a need for intervention, wherein said grip element is provided with two tongues, which are parallel to a plurality of flexible jaws and are intended to be inserted and to slide in corresponding indentations on an outside of said body, and in which said tongues have lateral locking teeth, which are intended to intercept opposing teeth on sides of said indentations in order to prevent the detachment of said grip element when said grip element is stopped in relation to said body.
