[0020] This application provides a spring connector that adopts an integrated design with ultra-thin materials and a double lever arm structure, reducing the space ratio. While meeting the requirements of structural miniaturization, it can enhance the elasticity of the spring, increase the service life of the spring, and improve the stability of the spring connection. It is formed by stamping, which simplifies the forming process and improves production efficiency. In addition, the spring can realize signal transmission between the cable and the motherboard, and can also fix the cable, making it multifunctional.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] like Figures 1 to 3 The following is an embodiment of this application:

[0023] A spring connector 1 includes a plate-shaped base 20, a wire clamp portion 30 formed by bending and extending one end of the plate-shaped base 20, and a spring body 40 formed by extending and bending the other end of the plate-shaped base 20. The wire clamp portion 30 has a double lever arm structure, and the spring body 40 includes an elastic arm 401, a contact portion 402, and a support portion 403. During the soldering process, the upper surface of the plate-shaped base 20 serves as the suction surface for SMT soldering, and the lower surface of the plate-shaped base 20 serves as the soldering surface for SMT soldering.

[0024] Furthermore, the double-arm structure of the wire clamp portion 30 is a wire clamp branch 304, which is equally spaced in the transverse direction of the plate-shaped base. The wire clamp portion 30 includes a bending portion 301, a wire clamp arm 302, and a connecting arm 303. A wire clamping groove 50 is formed between the wire clamp arm 302 and the connecting arm 303. The wire clamping groove 50 has an opening for inserting the cable, and the opening faces upward. The opening diameter of the wire clamping groove is smaller than its bottom diameter. When the cable is inserted into the wire clamping groove 50, it can prevent the cable from shifting and prevent it from coming out of the fixed groove. The joints of the bending portion 301, the wire clamp arm 302, and the connecting arm 303 are all smooth arc structures to prevent the burrs from the stamping process from scratching the cable sheath, thus providing protection.

[0025] In this embodiment, the elastic arm 401 is a wavy annular structure formed by one end of the plate-shaped base 20 extending obliquely upward. When the spring is subjected to force, the wavy annular elastic arm disperses the force value, reduces the deformation of the spring, and increases the service life of the spring. A contact portion 402 is provided on the elastic arm 401 in the direction away from the plate-shaped base 20. The contact portion 402 is a protruding structure, which is used to improve the stability of the contact between the contact portion 402 and the component, thereby improving the stability of the spring signal transmission. The support portion 403 is a flat plate structure formed by extending from the plate-shaped base 20, and the support portion 402 is located below the elastic arm 401.

[0026] The wire clamp is made of an ultra-thin material with a thickness of 0.08mm, and the spring body has an ultra-low height of 0.2mm.

[0027] In this embodiment, the wire clamp 30 is designed with an ultra-thin material of 0.08mm thickness, reducing its size and achieving miniaturization and lightness, thus reducing the space occupied by the spring. The double-arm structure design reduces the deformation of the spring when the cable is inserted into the clamping groove 50, enhancing the spring's elasticity and increasing its lifespan. The spring body 40 is designed with an ultra-low height of 0.2mm, effectively reducing the area occupied by the spring on the PCB board and achieving spring miniaturization.

[0028] In the above embodiments, for ease of manufacturing, the spring connector disclosed in this utility model is an integral structural component; specifically, the spring only needs one set of molds to be integrally formed by stamping process, which greatly reduces the cost of molds and stamping equipment, simplifies the process, and improves production efficiency.

[0029] In summary, the spring connector provided by this utility model adopts an integrated design with ultra-thin materials and a double-arm structure. It is integrally formed by stamping process, which improves production efficiency, reduces the space ratio of the spring, achieves miniaturization and lightness, enhances the elasticity of the spring, increases the life of the spring, and ensures the stability of signal transmission. In addition, the spring can realize signal transmission between the cable and the motherboard, and can also fix the cable, thus having multiple functions.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
