[0010] The utility model has the advantages that the high pressure connector with a primary and secondary spring structure is assembled with an additional primary spring structure in the anti-touch needle avoidance hole, the anti-touch hole is reasonably utilized, the inner and outer spring leaves carry current at the same time, the overcurrent capacity of the high pressure connector is greatly improved under the same volume, and the overcurrent capacity of the high pressure connector is greatly improved under the same wire diameter. BRIEF DESCRIPTION OF DRAWINGS

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 This is a structural schematic diagram of the cross-sectional view of this utility model;

[0014] The components include: 1. Male terminal, 2. Male terminal inner spring, 3. Male terminal anti-touch cap, and 4. Copper busbar.

[0015] 5. Anti-touch pin, 6. Female terminal anti-touch cap, 7. Female terminal inner spring, 8. Female terminal sleeve, 9. Anti-touch pin clearance hole. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0017] like Figure 1 , 2 As shown, it includes a male terminal 1 and a female terminal sleeve 8. One end of the male terminal 1 is a flattened connection end, and the other end of the connecting sleeve is provided with an anti-touch pin avoidance hole 9. The anti-touch pin avoidance hole 9 is pre-set with a male terminal inner spring 2. The other end of the connecting sleeve is provided with a male terminal anti-touch cap 3. The female terminal sleeve 8 is provided with a female terminal inner spring 7. After the female terminal inner spring 7 is set in the female terminal sleeve 8, it is sleeved on the connecting sleeve at the other end of the male terminal 1. The female terminal inner spring 7 is provided with an anti-touch pin 5. The anti-touch pin 5 passes into the male terminal inner spring 2, and its front end is sleeved with a female terminal anti-touch cap 6. A copper busbar 4 is welded on the female terminal sleeve 8. The flattened connection end of one end of the male terminal 1 is provided with a threaded connection hole.

[0018] The overall structure incorporates a new male terminal inner spring 2 structure, and the anti-touch pin is made of T2 copper material. When the female terminal mates with the male terminal, the female terminal inner spring 7 contacts the outer wall of the male terminal, forming the first conductive layer. Then, the male terminal inner spring 2 contacts the outer wall of the anti-touch pin 5, forming the second conductive layer. Both conductive layers conduct electricity simultaneously, significantly improving the overcurrent capability of the high-voltage connector.

[0019] The male inner spring 2 includes, but is not limited to, a crown spring, a torsion spring, a wire spring, or a wave spring. An additional male inner spring 2 structure is assembled in the anti-touch pin avoiding hole 9, the anti-touch pin avoiding hole 9 is reasonably utilized, the male inner spring 2 and the female inner spring 7 form inner and outer spring blades which simultaneously carry current, so that the overcurrent capacity of the high-voltage connector is greatly improved under the same volume, and the overcurrent capacity of the high-voltage connector is greatly improved under the same wire diameter.

[0020] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
