Description

Quick plug-in type cable joint for power distribution network Technical Field The utility model belongs to the technical field of cable joints, and particularly relates to a quick plug-in type cable joint for a power distribution network. Background The cable joint is also called a cable head. After the cable is laid, the sections must be connected as a unit in order to form a continuous line, and these points of connection are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, while the cable joints at both ends of the line are called terminal heads. The cable connector is used for locking and fixing the incoming and outgoing lines, and plays a role in preventing water, dust and vibration. The existing cable connector is generally provided with a locking structure for preventing the cable from being separated from each other due to external force action (such as tripping the cable when a worker walks) after the cable is laid, however, when the cable is subjected to external force, the cable is easy to break due to the large pulling action due to the fixation of the locking structure, so that the cable is inconvenient for a user to use.
