Problems solved by technology
[0005] The purpose of the present invention is to provide an explosion-proof cable sealing joint to solve the problem that the existing explosion-proof cable sealing joint in the above-mentioned background technology has an excessive clamping force in the process of clamping the cable for a long time, which may cause the cable surface to be locally overstressed. The surface is damaged and the clamping force is too small, which will easily cause the cable to shake

The invention relates to the technical field of cable installation parts, and discloses an explosion-proof cable sealing joint in the technical field of cable installation parts. The explosion-proof cable sealing joint comprises a cable, an insulation sleeve, a fixing part and a propelling part, wherein the tail end of the cable is wrapped with the insulation sleeve, the fixing part comprises an installation plate, a fixing cylinder and a first conical cylinder, and external threads are uniformly arranged on the outer wall of the fixing cylinder; the first conical cylinder is fixedly arranged in the inner cavity of the fixing cylinder, and the bottom of the first conical cylinder is provided with an inner conical surface; the propelling part comprises a base, a bottom cylinder, a second conical cylinder, a long cylinder bearing, a connecting cylinder and a rotating cylinder, anti-skid teeth are evenly arranged on the outer wall of the rotating cylinder, internal threads are arranged at the upper end of the inner wall of the rotating cylinder, the rotating cylinder is in spiral fit with the fixed cylinder, and an inner groove is formed in the inner wall of the middle of the rotating cylinder. In the cable sealing installation process, the installation requirement of sealing installation is ensured, the clamping stability is ensured by increasing the spiral torsion, and the problem that the surface of the cable is damaged due to the fact that the local stress of the surface of the cable is too large due to too large force is prevented.
Description
technical field [0001] The invention relates to the technical field of cable mounting parts, in particular to an explosion-proof cable sealing joint. Background technique [0002] When the cabinet body is installed with external cables, it is often necessary to open cabinet installation holes on the cabinet wall, while the explosion-proof cable gland is a fixture installed in the cabinet installation holes and for the external cables to pass through. It is used to strengthen the connection between the external cables and the cabinet. The sealing performance between the mounting holes of the body so as to meet the explosion-proof requirements. [0003] Excessive clamping force of the existing explosion-proof cable sealing joint in the process of clamping the cable for a long time may easily cause the surface of the cable to be partially stressed and cause surface damage, and the clamping force is too small to easily cause the cable to shake. [0004] Based on this, the prese...
