Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to a cable clamp for preventing cables from cracking. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. During use, a protective sheath is sheathed on the outside of the cable to protect it and prevent leakage. When using this type of cable with a sheath, the outer sheath will expand and contract depending on the ambient temperature. Long-term use may cause the cable to crack. Therefore, a clamp is clamped on the outside of the cable. As the frequency of cable use increases, in order to ensure that the cable is not easy to crack during use, the function of the upper end of this type of clamp is also improved, so that it can provide better protection.

[0003] In view of this, Chinese patent number CN105870848A proposes a cable clamp for preventing cable cracking. The cable clamp can timely feedback the pressure of the outer wall of the cable squeezed by the clamp, and effectively control to avoid damage to the outer wall of the cable and leakage causing electric shock injuries. However, during the clamping process, the existing cable clamps adjust the clamping force to prevent the cable from cracking, but the effect is still not obvious. At the same time, excessive clamping can easily cause cable deformation, thereby reducing the practicality of the device. Utility Model Content
