Description

Technical Field

[0001] The utility model relates to the technical field of cable joints, in particular to a wear-resistant and corrosion-resistant cable joint. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention.
