However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0023] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0024] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense.

[0027] Refer to Figure 1 , an embodiment of this application provides a connector terminal 10, and the connector terminal 10 can be used for two-way plugging. The connector terminal 10 includes a connection section 100, a first plugging section 200 and a second plugging section 300. The first plugging section 200 is connected to one end of the connection section 100, and the second plugging section 300 is connected to the other end of the connection section 100. The first plugging section 200 includes a plurality of clamping arms 210 arranged along the circumferential direction, and the plurality of clamping arms 210 enclose to form a first jack 220. The second plugging section 300 is provided with a second jack 310, and a partial area of the hole wall of the second jack 310 protrudes inward in the radial direction for tightly abutting against a pin.

[0028] In the above-mentioned connector terminal 10, the first insertion section 200 is provided with a first insertion hole 220, and the second insertion section 300 is provided with a second insertion hole 310. Both the first insertion hole 220 and the second insertion hole 310 can be inserted and mated with a pin, so that the connector terminal 10 can achieve two-way insertion and mating. The first insertion section 200 and the second insertion section 300 are directly connected to the connection section 100, with a simple structure, and the connection section 100 is used for limiting and mating with the insulator, and the fixing method is simple. It is easy to understand that, compared with the conventional technology in which two elements with insertion holes are respectively provided and connected and fixed together by a complex intermediate structure, the first insertion section 200 and the second insertion section 300 provided in this application are directly connected to the connection section 100 and fixed to the insulator through the connection section 100, which not only has a simple structure but also is convenient for fixing.

[0029] Furthermore, a plurality of clamping arms 210 surround to form the first insertion hole 220, which can improve the stability of the insertion and mating between the first insertion hole 220 and the pin. A partial area of the hole wall of the second insertion hole 310 protrudes inward in the radial direction, which can be closely mated with the pin, thereby also improving the stability of the cooperation between the second insertion hole 310 and the pin.

[0030] Furthermore, adjacent clamping arms 210 are spaced apart, and the clamping arms 210 have elastic properties.

[0031] Please refer to Figure 1 and Figure 2 , in an embodiment, the second insertion section 300 includes a plurality of ribs 320 arranged at intervals in the circumferential direction. A partial area of the ribs 320 protrudes inward in the radial direction to form an inner convex arc shape. By inserting and mating the inner convex part of the ribs 320 with the pin, the stability of the insertion and mating between the pin and the second insertion hole 310 can be improved.

[0032] Furthermore, as Figure 3 , it can be the intermediate area between the two ends of the ribs 320 that protrudes inward in the radial direction.

[0033] Furthermore, the ribs 320 have elastic properties. The second insertion section 300 is also provided with a plurality of relief grooves 350, and the relief grooves 350 are arranged between adjacent ribs 320 to enable the ribs 320 to have a certain elastic movement space, which is convenient for stable insertion.

[0034] Please refer to Figure 3, in one embodiment, the dimension of the rib 320 protruding radially inward is S, and the maximum radius of the inner cavity of the second jack 310 is R1, where 0.25R1 ≤ S1 ≤ 0.35R1. It can be understood that the smaller hole-like structure formed by the parts where the rib 320 protrudes inward is used for plugging and matching with the pin. Correspondingly, the second jack 310 can have a relatively larger radial dimension to facilitate the pin to penetrate into the second jack 310. The rib 320 can guide the pin penetrating into the second jack 310 to be inserted into the smaller hole-like structure.

[0035] Please continue to refer to Figure 3 , in one embodiment, the regions with the largest inward protrusion amplitude of each rib 320 are located at the same position on the axis O of the second plugging section 300 (such as Figure 3 the P position shown), so that each rib 320 can cooperate with each other to jointly clamp the pin and improve the stability of the axial position of the pin. Of course, in other embodiments, the regions with the largest inward protrusion amplitude of each rib 320 can also be set at different positions on the axis O of the second plugging section 300. At this time, each rib 320 can support the pin at multiple points to reduce the shaking of the pin.

[0036] Please refer to Figure 1 , in one embodiment, the first jack 220 forms a first guiding hole 230 at the end of the first plugging section 200 facing away from the second plugging section 300, and the first guiding hole 230 is used for the pin to penetrate. Along the direction of the axis O of the first plugging section 200 pointing to the second plugging section 300, the inner diameter of the first guiding hole 230 gradually decreases to facilitate guiding the pin to penetrate into the first jack 220 and improve the smoothness of the plugging.

[0037] Please continue to refer to Figure 3 , in one embodiment, the second plugging section 300 further includes a connecting ring 330. One end of each rib 320 is connected to the connecting section 100, and one end of each rib 320 facing away from the first plugging section 200 is connected to the connecting ring 330. The connecting ring 330 is provided with a second guiding hole 340 communicating with the second jack 310. Along the direction of the axis O of the second plugging section 300 pointing to the first plugging section 200, the inner diameter of the second guiding hole 340 gradually decreases. Since the connecting ring 330 is located at one end of the connecting ring 330 facing away from the first plugging section 200, the pin usually penetrates into the second plugging section 300 from the second guiding hole 340. Therefore, by setting the inner diameter of the second guiding hole 340 to gradually decrease in the said direction, the pin can be gradually guided into the second jack 310 to improve the smoothness of the plugging.

[0038] Please refer to Figure 1 and Figure 4, in one embodiment, a partial area of the outer peripheral wall of the connecting section 100 protrudes radially outward to form a convex portion 110, and the convex portion 110 is used for interference fit with the insulator. With such a setting, the connecting section 100 can be connected and fixed to the insulator through a simple structure.

[0039] Please refer to Figure 4 , in one embodiment, the outer radius of the connecting section 100 is R2, and the dimension that the convex portion 110 protrudes radially from other areas of the outer periphery of the connecting section 100 is S2, where 0.05R2 ≤ S2 ≤ 0.15R2. With such a setting, the smoothness of the insertion of the connector terminal 10 into the insulator and the stability of the interference fit between the connector terminal 10 and the insulator can be taken into account.

[0040] Please refer to Figure 4 and Figure 5 , in one embodiment, the connector terminal 10 is provided with a splicing gap 400 extending along the axis O. The splicing gap 400 includes an opposite first surface 410 and a second surface 420, and the connector terminal 10 can be wound from an initial state to a finished state by stamping. When the connector terminal 10 is in the initial state, the connector terminal 10 is in a flat plate shape, and the first surface 410 and the second surface 420 are arranged back to back. When the connector terminal 10 is in the finished state, the connector terminal 10 is in a hollow tubular shape, and the first surface 410 and the second surface 420 are spaced opposite or in contact with each other to form the splicing gap 400.

[0041] In other words, the connector terminal 10 provided by the present application can be formed by stamping a plate-like material, and the processing method is simple. Moreover, compared with the terminal structure processed by traditional turning, such a setting saves more materials. Further, the connector terminal 10 is formed by stamping, and the dimensions of the first jack 220, the second jack 310, etc. have high precision and good consistency of the insertion and extraction force, so that the reliability is high and the insertion and extraction are smooth when the connector terminal 10 is inserted and mated with the pin.

[0042] It should be noted that the connector terminal 10 provided by each embodiment of the present application is convenient for stamping. For example, a relief groove 350 can be formed between adjacent ribs 320 by stamping, the ribs 320 can be formed into an inwardly convex arc structure by stamping, and the convex portion 110 can be formed into a shape protruding from other areas of the connecting section 100 by stamping.

[0043] Please refer to Figure 2 and Figure 4, in one embodiment, the convex portion 110 protrudes along the first radial direction K1, and the splicing gap 400 communicates inside and outside the connector terminal 10 along the second radial direction K2, and the first radial direction K1 is perpendicular to the second radial direction K2. It can be understood that the convex portion 110 is formed by stamping and protrudes along the first radial direction K1, that is, stamping is performed along the direction perpendicular to the first radial direction K1 (which is the second radial direction K2 in this embodiment). In other words, the direction of stamping to form the convex portion 110 is the same as the communication direction of the splicing gap 400. Since the connector terminal 10 is not a complete and integral tubular structure, stamping along the second radial direction K2 can reduce the probability of unpredictable deformation occurring at the position of the splicing gap 400 during the stamping process, facilitating the stable formation of the convex portion 110.

[0044] For the convenience of understanding the stamping process of the jack-type terminal structure, a simple description is given below:

[0045] S1, Provide a sheet. The shape and specific dimensions of the sheet can be adaptively selected according to the required connector terminal 10.

[0046] S2, Punch out the shape of one end of the connector terminal 10 when it is unfolded on the sheet. For example, the shape of the clamping arm 210 can be punched out at this time.

[0047] S3, Punch out the shape of the other end of the connector terminal 10 when it is unfolded on the sheet. For example, the avoidance groove 350 and the rib 320 can be punched out at this time.

[0048] S4, Round the sheet to form the connector terminal 10.

[0049] S5, Stamp the rounded connector terminal 10 to form the convex portion 110.

[0050] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0051] The above-described embodiments only express several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
