Cable connectors are also called cable heads. After the cable is laid, in order to make it a continuous line, all the lines must be connected into a whole. These connection points are called cable joints.
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. Cable connectors are used to lock and fix incoming and outgoing wires, which are waterproof, dustproof and shockproof.
