Cable clamping device

Claim 2

A cable clamping device adapted to assure an electrical and mechanical connection between two bare sections of electric cables, by clamping said sections together, comprising two distinct elements that can be assembled together to form a ring surrounding said two bare sections, and clamping means for clamping together said sections disposed within the ring thus formed, wherein said two elements comprise relatively thick plates curved around respective longitudinal axes in the form of U''s of the same width, the ends of the wings of said U''s being cut out into complementary tenons and mortises such that said wings can be fitted together two by two to close the ring, only by lateral displacement until said axes lie in a common middle plane, said device being adapted to hold said cable sections, even when of varied diameters, one above the other, in said common middle plane of the assembled U''s, said clamping means comprising a screw lying in said common middle plane perpendicular to the direction of said cable sections so that said clamping means can urge one cable section towards the other cable section during clamping, said screw being of diameter considerably less than the interior width of each U and being accessible or passing through a hole formed in the bottom of one of the U''s which hole is also of diameter considerably less than the interior width of the U''s and a locking member, other than said screw, disposed inside said ring at the level of the tenons and mortises, capable of locking said U''s against transverse separation, said locking member having a Width that is only slightly less than the interior width of each U.

Claim 3

A cable-clamping device according to claim 1, wherein said tenons have the general form of a T.

Claim 4

A cable clamping device according to claim 1, wherein said clamping means comprises a support disposed within the ring and having a threaded hole which cooperates with said screw, said support bearing, during clamping, against the U plate which is provided with the hole, so as to provide a reaction for the clamping force, and enabling said screw to be sunk within the ring.

Claim 5

A cable-clamping device according to claim 1, wherein said locking member is a separate filler adapted to be introduced into the closed ring along a direction parallel to said common middle plane.

Claim 6

A cable-clamping device according to claim 4, wherein said locking member is situated between the two cable sections and constitutes a block for distributing the clamping pressure.

Claim 7

A cable-clamping device according to claim 4, wherein said locking member comprises a cable section itself.

Claim 8

A cable clamping device adapted to assure an electrical and mechanical connection between two bare sections of electric cables, by clamping said sections together, comprising two distinct elements that can be assembled together to form a ring surrounding said two bare sections and clamping means for clamping together said sections disposed within the ring thus formed, wherein said two elements comprise relatively thick plates curved around respective longitudinal axes in the form of U''s of the same width, the ends of the wings of said U''s being cut out into complementary tenons and mortises such that said wings can be fitted together two by two to close the ring, only by lateral displacement until said axes lie in a common middle plane, said device being adapted to hold said cable sections, even when of varied diameters, one above the other, in said common middle plane of the assembled U''s, said clamping means comprising a screw lying in said common middle plane perpendicular to the direction of said cable sections so that said clamping means can urge one cable section towards the other cable section during clamping, said screw being of diameter considerably less than the interior width of each U and being accessible or passing through a hole formed in the bottom of one of the U''s which hole is also of diameter considerably less than the interior width of the U''s, and a locking member other than said screw, disposed inside the said ring at the level of the tenons and mortises, capable of locking said U''s against transverse separation, said locking member having a width that is only slightly less than the interior width of each U, wherein said clamping means comprise a support disposed within the ring and having a threaded hole which cooperates with said screw, said support bearing, during clamping, against the U plate which is provided with the hole, so as to provide a reaction for the clamping force, and wherein said support is in a form of a U adapted to be mounted at will inside said closed ring so that its concavity follows the concavity of one of the plates or on the contrary is opposed to the concavity of said one plate.

Claim 9

A cable clamping device adapted to assure an electrical and mechanical connection between two bare sections of electric cables, by clamping said sections together, comprising two distinct elements that can be assembled together to form a ring surrounding said two bare sections and clamping means for clamping together said sections disposed within the ring thus formed, wherein said two elements comprise relatively thick plates curved around respective longitudinal axes in the form of U''s of the same width, the ends of the wings of said U''s being cut out into complementary tenons and mortises such that said wings can be fitted together two by two to close the ring, only by lateral displacement until said axes lie in a common middle plane, said device being adapted to hold said cable sections, even when of varied diameters, one above the other, in said common middle plane of the assembled U''s, said clamping means comprising a screw lying in said common middle plane perpendicular to the direction of said cable sections so that said clamping means can urge one cable section towards the other cable section during clamping, said screw being of diameter considerably less than the interior width of each U and being accessible or passing through a hole formed in the bottom of one of the U''s which hole is also of diameter considerably less than the interior width of the U''s, and a locking member other than said screw, disposed inside the said ring at the level of the tenons and mortises, capable of locking said U''s against transverse separation, said locking member having a width that is only slightly less than the interior width of each U, wherein said clamping means comprise a support disposed within the ring and having a threaded hole which cooperates with said screw, said support bearing, during clamping, against the U plate which is provided with the hole, so as to provide a reaction for the clamping force, and wherein said support is in a form of a U adapted to be mounted at will inside said closed ring so that its concavity follows the concavity of one of the plates or on the contrary is opposed to the concavity of said one plate.
