[0023] Example 1

[0024] like Figures 1-3 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting terminals; Figure 2 This is another three-dimensional structural diagram of the connecting terminal; Figure 3 This is a front view of the connection terminal. The connection terminal includes a support base 1 and a coil spring 2. The coil spring 2 is disposed on the support base 1 and is connected to other components through the support base 1. An external pin is inserted into the coil spring 2, and current can be conducted between the external pin, the coil spring 2, and the support base 1.

[0025] The coil spring 2 includes a fixed plate 21, multiple first spring pieces 22, and multiple second spring pieces 23. The fixed plate 21 is sleeved on one end of the support base 1. The multiple first spring pieces 22 are spaced apart at the end of the fixed plate 21 away from the support base 1, and the multiple second spring pieces 23 are spaced apart at the end of the fixed plate 21 away from the support base 1. The multiple first spring pieces 22 and multiple second spring pieces 23 are staggered, that is, there is a second spring piece 23 between two adjacent first spring pieces 22, and similarly, there is a first spring piece 22 between two adjacent second spring pieces 23. The multiple first spring pieces 22 and multiple second spring pieces 23 can all deform relative to the fixed plate 21. Specifically, the fixed plate 21, the multiple first spring pieces 22, and the multiple second spring pieces 23 together form a socket 20, into which an external pin is inserted. During the insertion of the external pin, the multiple first spring pieces 22 and multiple second spring pieces 23 are subjected to force and expand outward. At this time, the multiple first spring pieces 22 and multiple second spring pieces 23 deform relative to the fixed plate 21.

[0026] Furthermore, the length of the first spring 22 is L, and the length of the second spring 23 is H, where L > H. In other words, when the external pin is inserted, the external pin will first contact the first spring 22, and then contact the second spring 23 after being inserted to a certain position. This divides the contact between the external pin and the coil spring 2 into two segments, which helps to reduce the external force required for the insertion of the external pin, thereby achieving the effect of saving effort.

[0027] Furthermore, the width of the end of the first spring 22 away from the fixing plate 21 is D, and the width of the end of the second spring 23 away from the fixing plate 21 is S, where D > S. By increasing the width of the end of the first spring 22 away from the fixing plate 21, the contact area between the first spring 22 and the external pin can be increased as much as possible while ensuring the effort-saving effect when inserting the external pin, so as to improve the current carrying capacity of the connection terminal.

[0028] The first spring contact 22 has a first arc surface 221, which is located at the end of the first spring contact 22 away from the fixing piece 21. The first arc surface 221 protrudes towards the center of the insertion hole 20. The first arc surface 221 increases the contact points between the first spring contact 22 and the external pin, thereby improving the current conduction effect between them. In addition, the first arc surface 221 can also guide the external pin when it is inserted. In use, the outer surface of the external pin abuts against the first arc surface 221.

[0029] The second spring contact 23 has a second arc surface 231, which is located at the end of the second spring contact 23 away from the fixing piece 21. The second arc surface 231 protrudes towards the center of the insertion hole 20. The second arc surface 231 increases the contact points between the second spring contact 23 and the external pin, thereby improving the current conduction effect between them. In addition, the second arc surface 231 can also guide the external pin when it is inserted. In use, the outer surface of the external pin abuts against the second arc surface 231.

[0030] In practical applications, the fixing plate 21, multiple first spring pieces 22, and multiple second spring pieces 23 are integrated into a single structure. In practice, the fixing plate 21, multiple first spring pieces 22, and multiple second spring pieces 23 can be formed using a stamping process, and then the entire coil spring 2 can be wound around one end of the support base 1 using a rolling process. Finally, the coil spring 2 is welded to the support base 1. Using a stamping process not only improves production efficiency but also significantly reduces production costs.

[0031] In this embodiment, the coil spring 2 is made of a material with high conductivity and high yield strength, such as materials similar to those used in existing crown springs and torsion springs.

[0032] In summary, by setting the first spring piece 22 and the second spring piece 23 to different lengths along the axial direction, the first spring piece 22 and the second spring piece 23 contact the external pin one after the other. The segmented contact method reduces the thrust required for inserting the external pin, thereby achieving the effect of saving effort.
