Description

Technical Field

[0001] This utility model relates to a pluggable elbow-type fully insulated cable connector. Background Technology

[0002] Plug-in elbow type fully insulated cable joints are widely used in substations, transmission lines, and other applications. They consist of a front connector and a rear surge arrester that connects to the rear end of the front connector. Traditionally, the front connector and the rear surge arrester are only connected by the surge arrester cone at the front end of the rear surge arrester and the front connector channel of the front connector. Over long-term use, due to external vibration or impact, and because there is no locking device at the connection point, the connection is prone to loosening or displacement, affecting the stability and reliability of the connection between the front connector and the rear surge arrester. The use of plug-in elbow type fully insulated cable joints poses a safety hazard. Therefore, improvements and optimizations have been made to address this issue. Utility Model Content

[0019] like Figure 1-7As shown, the plug-in elbow-type fully insulated cable connector of this utility model includes a front connector 1, a rear surge arrester 2 that connects to the rear end of the front connector 1, a locking ring 3, and a locking clamp 4. The front connector 1 has a horizontally arranged front connector mating part 6 and a vertically arranged cable insertion part 7. The front connector mating part 6 has a horizontally arranged front connector channel 8. The rear surge arrester 2 has a horizontally arranged surge arrester mating part 9 and a vertically arranged surge arrester inner core insertion part 10. The front end of the surge arrester mating part 9 has a surge arrester cone head 11 and a surge arrester connecting boss 12 corresponding to the rear end of the front connector channel 8. The inner side of the surge arrester connecting boss 12 has a surge arrester locking part 13. A locking mechanism is formed between the surge arrester connecting boss 12 and the outer wall of the rear end of the front connector mating part 6. The locking ring 3 is limited by the locking ring mounting groove 14. The outer wall of the rear end of the front connector docking part 6 is provided with a front connector rear locking groove 16 for the arrester locking part 13 to lock. The outer wall of the arrester connecting boss 12 is provided with a clamp insertion groove 15 for the installation and positioning of the locking clamp 4. The locking clamp 4 is used to lock the locking ring 3. The locking ring 3 clamps the outer wall of the rear end of the front connector 1 to strengthen the connection tightness between the front connector 1 and the rear arrester 2. It effectively prevents the loosening or displacement of the front connector 1 and the rear arrester 2 due to external vibration or impact, and improves the connection stability of the equipment.

[0020] The locking ring 3 is made of metal, which can enhance the clamping force and firmness of the locking ring 3. The inner wall of the locking ring is provided with locking ring clamping teeth 19 at intervals. The outer wall of the rear end of the front connector docking part 6 is provided with front connector anti-displacement arc grooves 20 corresponding to the locking ring clamping teeth 19 at intervals.
