[0023] See also Figure 2 , Figure 3 and Figure 5 A reset spring 74 is sleeved and installed on the surface of the conductive column 71 and below the fixing ring 72. By using the reset spring 74, the conductive column 71 can be reset, so that it can be automatically reset when the fastening screw 5 is removed, saving the time of manual reset, and the conductive column 71 can be automatically separated from the PCB board contact. The top and bottom of the reset spring 74 are fixedly connected to the bottom of the fixing ring 72 and the top of the mounting frame 4 respectively, and the bottom of the conductive column 71 penetrates to the bottom of the mounting frame 4;

The jumper body 61 is the main metal connection, and the bottom surfaces of the two ends are flush. The middle part is wrapped with high-temperature glue. The bottom of the glue-wrapped part is flush with the bottom surfaces of the two ends of the jumper body 61, and the top is higher than the jumper body 61. The components are all wrapped except the welding parts at the two ends, which plays the role of insulation and leakage prevention, and the heat dissipation performance is faster and better. The surfaces of the two ends of the jumper body 61 have a tin-plated layer, which plays the role of easy welding and anti-oxidation. The middle glue-wrapped part uses a low-temperature plasma sprayed surface coating to improve the adhesion of the surface of the jumper body 61, and a graphene coating is added to play a role of fast heat dissipation.
