Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to a cable connector device that facilitates insertion and removal. Background Technology

[0002] In modern power transmission and distribution systems, cross-linked polyethylene insulated power cables are widely used in urban underground power grids, power plant lead-out lines, and other scenarios. However, due to limitations in production technology, site conditions, and transportation, the cable length is limited, requiring connection and extension to meet construction requirements. This makes cable joints an indispensable part of the power system.

[0003] Traditional cable joints have revealed numerous problems in practical applications. During splicing and disassembly, the electrical connection between cables is unstable and prone to poor contact. This not only affects the stability of power transmission but may also lead to safety hazards such as localized overheating and discharge. In addition, the mechanical connection method of the joints is relatively complex. During assembly, workers need to spend a lot of time and effort on operations such as cleaning up stripping marks, ensuring a firm connection of the grounding wire, and ensuring that the terminals are tightly crimped. The assembly process is cumbersome and requires a high level of technical skill from the operators. If a problem occurs in any link, it may cause joint failure and reduce the reliability of power operation. Utility Model Content

A joint sleeve spring is provided between the outer side of the joint sleeve and the protective outer sleeve of the joint, and the joint sleeve spring is sleeved on the outer side of the joint sleeve.

[0008] Furthermore, the connector sleeve is provided with a terminal sleeve inside, and the terminal pin is inserted into the internal hole of the terminal sleeve and electrically connected to the terminal sleeve. The terminal sleeve slides back and forth along the internal hole of the connector sleeve.
