They are usually made of metal and are ring-shaped. They can lock and fix the cable connections to prevent the cable connections from loosening and causing secondary breaks. Cable clamps play an important role in the fields of power transmission, communications, construction, etc. They can effectively protect cables and ensure their normal operation.

Magnet holes 12 are provided at the ends of the upper clamp 1 and the lower clamp 14, and a magnet column 13 is provided in each magnet hole 12. The magnet column 13 is attracted to the cable bonding iron plate 8 by magnetic force.

[0023] The card set 4 is movably installed in the card slot 3, and the screw rod 5 is inserted into the card set 4, so that the screw rod 5 is limited along the axis direction of the upper clamp 1 and the lower clamp 14 when inserted into the card set 4, and two protrusions are symmetrically arranged on the surface of the card set 4. It is convenient for the card set 4 to be installed in the card slot 3 through the two protrusions.

[0024] During installation, the inner surfaces of the upper clamp 1 and the lower clamp 14 are provided with a limiting groove 7, and one end of the corresponding cable bonding iron plate 8 is installed in the limiting groove 7.
