In order to further firmly fix the cable and each internal component, the clamping hook plate is arranged between the fixing cap and the mounting box sleeve, and an insulating bolt is bolted between the connecting guide plate and the mounting box sleeve.

In order to facilitate the installation and the disassembly of the fixed connecting bolt, a plurality of limiting grooves are formed in the two opposite side surfaces of the installation box sleeve, limiting plates are welded on the two opposite side surfaces of the fixed cap, and the limiting plates are of an L-shaped plate structure; the limiting plate is clamped with the limiting groove in a sliding mode.

A partition plate is adhered to the inner surface of the mounting box sleeve, a fastening pressing block is nested in the mounting box sleeve, and a fastening pressure spring is welded between the fastening pressing block and the partition plate; the fastening pressing block is contacted with the connecting guide rod; the clamping plate can be matched with the fixed connecting bolt to further clamp and fix the fixed connecting bolt through the elastic action of the fastening pressure spring;

in order to further facilitate the installation of each internal component, a plurality of sliding grooves are formed in the inner side surface of the installation box sleeve, and the fastening pressing block is clamped with the sliding grooves in a sliding mode through the sliding blocks.

In order to ensure the safety performance of the integral fixed connecting piece, the mounting box sleeve, the clamping plate, the fixing cap, the fastening pressing block and the partition plate are all insulators, and meanwhile, in actual work, a layer of insulating material needs to be coated outside the integral fixed connecting piece, and the fixed connecting piece comprises structures such as but not limited to an insulating tape, a rubber insulating sleeve and a sealed insulating box.

The invention has the following beneficial effects:

according to the cable fixing device, the cable is wound on the connecting guide rod of the fixed connecting bolt through the fixed connecting bolt and the connecting guide plate and then is connected through the connecting guide plate, and on one hand, the fixed connecting bolt is prevented from rotating and loosening by utilizing the limiting clamping relation between the fixing cap and the mounting box sleeve; on the other hand, the two connecting guide rods are clamped and connected by utilizing the clamping hook plates at the two ends of the connecting guide plate, so that the fixed connecting bolts can be prevented from being separated from each other; simultaneously, the clamping plate with the elastic function is arranged at the mounting groove of the mounting box sleeve, so that the position of the fixed connecting bolt can be further limited, and looseness and falling off are prevented.
