Abstract

The invention discloses a cable fixing device, including a clamping head, an air bag, and a seal sleeve for allowing the cable to pass. The seal cover is deformable. The clamping head has a holding groove and is sleeved around the outer periphery of the seal sleeve. An annual space is formed between the inner wall of the holding groove and the outer wall of the seal cover. An air bag is annularlyarranged on the seal sleeve and located in the ring space. The air bag extrudes the seal sleeve to deform the seal sleeve so as to seal the cable in the seal sleeve. In the cable fixing device, the air bag is used to replace the traditional thread pretension-type cable locking, and after the air bag is inflated, the surface of the cable is uniformly pressed through the seal sleeve, so that the cable locking effect is better, and each of a plurality of cables is uniformly stressed, thereby improving the locking effect. Meanwhile, uniform pressing enables the seal sleeve to adhere to the cable more tightly, avoiding gaps and improving the seal effect.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a wire fixing device. Background technique [0002] The wire fixing device is a kind of connecting device often used in the power system. The existing cable joints all use thread pre-tightening to realize the locking function. Since the thread and the cable sheath are relatively hard, there is a gap between the thread and the cable, so that the sealing of the locking line is not good, especially when some cables run through When it is used, multiple cables and threads are prone to uneven force, not only the locking effect is poor, but also it is easier to form a gap, the sealing performance is worse, and there are deficiencies in occasions with high protection level requirements. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention discloses a wire fixing device, which solves the problem of poor sealing perf...
