Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 As shown, a pluggable GIS terminal includes a stress cone 1 and a connecting flange 5 disposed at the bottom of the stress cone 1;

[0023] A side connecting ring 11 is provided on the bottom side of the stress cone 1 near the side of the connecting flange 5. A snap-fit ​​slope post 13 is provided on the inner side of the side connecting ring 11. An inner connecting spring body 12 is provided on the inner side of the snap-fit ​​slope post 13. A limit moving groove 14 is provided inside the connecting flange 5. A limit moving post 15 is provided inside the limit moving groove 14. A moving compression ring 16 is provided at the end of the limit moving post 15. When the stress cone 1 and the connecting flange 5 are assembled, the side connecting ring 11 is in the connection method. On the outside of the flange 5, the snap-fit ​​slope column 13 will be snapped into the connecting flange 5 by the inner connecting spring body 12. When disassembly is required, pressing the moving compression ring 16 can compress the snap-fit ​​slope column 13 to make it retract. With the improvement of this utility model, after the plug-in GIS terminal is plugged in and installed, it does not need to be connected by screws. It only needs to be connected by snap-fit. At the same time, disassembly can be completed by simply pressing the moving compression ring 16. The operation is simple and quick, which can effectively improve the practicality of the plug-in GIS terminal.

[0024] like Figure 1As shown, a bottom heat-shrinkable sealing tube 7 is provided at the bottom of the connecting flange 5. The bottom heat-shrinkable sealing tube 7 and the connecting flange 5 are an integral structure. An inner connecting tape 6 is provided in the middle of the bottom heat-shrinkable sealing tube 7. The inner connecting tape 6 is made of rubber material. The bottom heat-shrinkable sealing tube 7 and the inner connecting tape 6 play a role in wrapping, restraining and protecting.

[0025] like Figure 1 As shown, an upper conical clip 2 is provided at the middle position of the stress cone 1, and a watch chain contact 3 is provided at the bottom position of the upper conical clip 2.

The pressure spring assembly 4 is connected to the stress cone 1 by a snap-fit ​​method. A grounding connection line 8 and a connecting cable 9 are provided at the center of the inner connecting tape 6. The inner connecting tape 6 is connected to the outer position of the grounding connection line 8 and the connecting cable 9 by a sleeve method. Through the pressure action of the pressure spring assembly 4, the contact between the stress cone 1 and the connecting cable 9 is made tighter, effectively controlling the electric field strength of the inner and outer interfaces, avoiding internal discharge and external flashover, and improving the insulation performance and electrical safety of the terminal.

[0027] like Figure 1 As shown, a grounding terminal 10 is provided at the end of the grounding connection line 8. The grounding terminal 10 is connected to the grounding connection line 8 by a sleeve compression method. The grounding terminal 10 is made of copper.
