A cable securing device

Abstract

The utility model relates to power cable technical field especially relates to a cable fastening device, including ceramic insulator and fastening assembly, the inside through -going of ceramic insulator is provided with the channel, and fastening assembly includes fastening plug pole and a plurality of arc clamping plates, and arc clamping plate sets up at one end of fastening plug pole, and arc clamping plate can bend to the axial line direction of fastening plug pole, and one end of fastening plug pole is provided with baffle, and the wire in the cable is connected in the middle part of a plurality of arc clamping plates, and arc clamping plate extends into the channel, and the channel makes a plurality of arc clamping plates contract to the wire direction and tighten the cable, and the baffle is tightly attached in the outside of channel, in the utility model, through the self -contracting clamping mechanism of arc clamping plate in the channel, the mechanical interlock of combining limit strip and annular clamping groove, effectively resist the structural looseness caused by external vibration, wind load or thermal expansion and contraction, ensure the long -term stable electrical connection between cable and insulator, greatly reduce the contact resistance increase and overheat risk.
