Description

Technical Field

[0001] The utility model relates to a connector, in particular to an energy storage connector. Background Art

[0002] The energy storage connector terminal is divided into a plug-in end 01 and a crimping end 02, and the two parts are crimped together through interference fit. Figure 1 As shown, firstly, the plug-in end and the pressing end stamping parts are riveted and fixed, and then the crown spring 03 is installed into the plug-in end, and finally the cover 04 is fixed to the plug-in end so that the crown spring cannot fall from the plug-in end.

[0003] Since the plug-in end and the crimp-on end are processed separately and then assembled into a finished product, the manufacturing cost of the product is high. Moreover, during use, the contact points of the plug-in end and the crimp-on end may deform due to temperature rise, resulting in an unstable connection between the two parts and a risk of failure. Utility Model Content

[0004] The technical problem solved by the utility model is that the energy storage connector terminal in the prior art has high manufacturing cost, and the contact points of the plug end and the crimp end are unstable after the temperature rises, which poses a risk of failure.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an integrated energy storage terminal, including a plug-in section and a crimping section, the plug-in section is equipped with a crown spring, the plug-in section and the crimping section are the two end parts of a cylindrical member, and the middle section of the cylindrical member is flattened and then bent to form a flat bent structure.

[0006] Compared with the split structure of the energy storage terminal in the prior art, the energy storage terminal of the utility model is integrally formed and has an integrated structure. The integrated terminal can better ensure stability and safety after temperature rise and prevent failure due to excessive temperature during use.

[0007] The cylindrical member is formed by rolling a plate. The plate includes a plug-in section forming part and a crimping section forming part at both ends, and a flat bending structure forming part in the middle section. Since the plug-in section diameter is smaller than the crimping section diameter, the width of the plug-in section forming part is smaller than the width of the crimping section forming part, and the flat bending structure forming part is in a trapezoidal shape. After the rolling process, the plug-in section and the crimping section are both in a straight cylindrical shape, while the middle section of the cylindrical member is in a conical shape, which is flattened and then bent to form a flat bending structure.

[0008] The inner wall of the plug section is provided with a crown spring anti-retraction step. The crown spring is formed by rolling the plate-like member into a circle with a notch. When installing, the crown spring is squeezed, the diameter becomes smaller, and the notch becomes smaller. After being installed into the plug section, the crown spring is reset, and its tail end abuts against the crown spring anti-retraction step, so that the crown spring cannot come out of the plug section.

[0009] The inner side wall of the plug section is provided with a limiting step opposite to the crown spring anti-retraction step. The crown spring is installed in the plug section, and its front end abuts against the limiting step and its rear end abuts against the crown spring anti-retraction step, so that the crown spring is stable in the plug section.

[0010] The utility model adopts an integrated rolling process design, which has a simple structure, is easy to process, improves production efficiency, and better reduces costs; the integrated terminal can better ensure the stability and safety of the structure after temperature rise, and prevent failure due to excessive temperature rise at the contact points of the connector and the crimping end during use; avoids the risk of product electrical performance failure and improves product quality.

[0023] like Figure 2 , Figure 3An integrated energy storage terminal includes a plug-in section 10 and a crimping section 20. The plug-in section is equipped with a crown spring 30. The plug-in section and the crimping section are the two end parts of a cylindrical member 40. The middle section of the cylindrical member is flattened and then bent to form a flat bent structure 50.

[0024] refer to Figure 2 The cylindrical member 40 is formed by rolling a plate 400. The plate 400 includes a plug-in section forming part 401 and a crimping section forming part 402 at both ends, and a flat bending structure forming part 403 located in the middle section. The width of the plug-in section forming part is smaller than the width of the crimping section forming part, and the flat bending structure forming part 403 is in a trapezoidal shape. After the rolling process, the plug-in section 10 and the crimping section 20 are both straight cylinders, and the diameter of the plug-in section is smaller than the diameter of the crimping section. The middle section of the cylindrical member 40 is conical, which is flattened and then bent to form a flat bending structure 50.

[0025] like Figure 2 The inner side wall of the plug section 10 is provided with a crown spring anti-retraction step 11 and a limit step 12, and the crown spring anti-retraction step 11 and the limit step 12 are arranged opposite to each other. Figure 4 The crown spring 30 is formed by rolling the plate-shaped member, leaving a notch 31. During installation, the crown spring 30 is squeezed, the diameter becomes smaller, the notch 31 becomes smaller, and it is installed into the plug section 10, and its front end abuts against the limit step 12. The crown spring 30 is installed in place, and the crown spring is reset in the plug section 10, and the diameter is restored to the original size. The tail end of the crown spring abuts against the crown spring anti-retraction step 11, so that the crown spring 30 cannot go out of the plug section 10, and the crown spring is stable in the plug section.
