System for locking an electrical-cable-supporting U-clamp to the crosspiece of an electrical pole

摘要

The subject of the present invention is a system for locking a cable-supporting U-clamp 1 to a crosspiece 2 of an electrical pole. The crosspiece 2 comprises two holes 4 which each receive the branches 3 of the U-clamp. Each hole 4 comprises an enlargement 4A dimensioned so as to ensure the passage of the nuts 7 and locknuts 8 and a restriction 4B into which the corresponding branch 3 of the U-clamp is engaged. A locking piece 11 mounted between the crosspiece and the stops 6 of the U-clamp interacts by locking with the branches of the latter and the enlargements 4A. This locking piece comprises two holes 12 through each of which passes a branch 3, each hole comprising an enlargement 12A and a restriction 12B and being turned in the opposite manner with respect to the corresponding hole 4. The piece 11 also comprises tabs 13 which each engage in an enlargement 4A when the branch 3 is placed in its restriction 4B and is trapped in the latter by the restriction 12B. The locking system enables the U-clamps to be assembled and dismantled without it being necessary to remove the nuts and the locknuts. <IMAGE>
