Abstract

The invention discloses a cable joint, comprising a conductor connection pipe, an insulator, a shielding net bushing and a water-blocking tape. The conductor connection pipe, the insulator and the shielding net bushing are arranged in order from inside to outside. The water-blocking tape is disposed at two ends of the shielding net bushing. One end of the insulator is provided with a semiconductive tape, which is wound on the outer side of the conductor connection pipe. The other side of the insulator is provided with a sheath bonding clamp and a ball spring. The sheath bonding clamp is mounted at the outer side of the ball spring. A holder is disposed at one side of the sheath bonding clamp and is provided with a rubber strip therein. The holder is in clamping and holding connection with the shielding net bushing. Steel wires are arranged in the insulator in the wave form. The cable joint is simple in structure, high in structure strength and long in service lifetime, is convenient to mount and is not easy to damage.

Description

technical field [0001] The invention relates to the technical field of cable connection, in particular to a cable joint. Background technique [0002] The cable joint is also called the cable head. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints, and the cable joints in the middle of the cable line are called intermediate joints. , and the cable joints at both ends of the line are called terminal heads. The cable joints are used to lock and fix the incoming and outgoing lines, and play the role of waterproof, dustproof and shockproof. Not paying attention to the installation quality: no bushing is installed where the insulating bushing should be used; no junction box is installed where the junction box should be used; even the splicing method is not used at the wire joint, but the illegal hook-shaped connection method is used . The contact resistance of th...
