[0029] This utility model embodiment provides a terminal, such as Figure 1-4As shown, the terminal includes a terminal body 1 and a spring structure 2. The terminal body 1 includes a connecting portion 11 with a mounting cavity 110 and a fixing portion 12 for welding and fixing. The mounting cavity 110 has multiple mounting ports along its circumference. The fixing portion 12 is located below one of the mounting ports and connected to the outer wall of the mounting cavity 110. The spring structure 2 can be inserted into and connected to the mounting cavity 110 through any mounting port. The spring structure 2 includes two vertically symmetrical springs 21 and a U-shaped plate 22 connecting the two springs 21. In this application, one end of the fixing portion 12 is fixed to the side wall of the connecting portion 11, and the other end can be ultrasonically welded to the high-voltage connector housing. The fixing portion 12 can be a fixing block adapted to the high-voltage connector housing. The shape of the connecting portion 11 can be... Figure 1-4 The square prisms, hexagonal prisms, octagonal prisms, decagonal prisms, dodecagonal prisms, etc. shown can be used as long as the corresponding spring structure 2 can be installed. For ease of description... Figure 1 , 3 Taking the quadrangular prism shown in Figure 4 as an example, the fixing part 12 is fixedly connected to one side of the connecting part 11, and the other three sides of the connecting part 11 are respectively provided with mounting holes. The spring structure 2 can be inserted into the mounting cavity 110 from any one of the mounting holes; Figure 3 and 4 The spring structure 2 shown has two different insertion directions, which allows the terminal to be inserted in both 180° and 90° directions. Of course, when the connecting part 11 has other structures, it can also be inserted in more directions. This solves the problem of the single insertion direction in the prior art, which cannot adapt to two-way insertion, effectively improving the applicability of the terminal and reducing production costs.

[0030] Furthermore, in this application, if Figure 2-4 The two springs 21 shown are symmetrical vertically. The free ends of the two springs 21 on the same side extend in two different directions. During installation, the spring structure 2 is simply inserted into the mounting cavity 110, and the free ends of the two springs 21 abut against the mounting cavity 110 to achieve a preliminary connection between the springs 21 and the mounting cavity. The connection structure is simple and easy to process. In the prior art, the two springs 21 are respectively connected to the terminal body 1. During installation, the installation position of the two springs 21 needs to be considered to ensure the clamping and electrical connection effect between the two springs 21. In this application, the two springs 21 and the U-shaped plate 22 are integrally formed, and there is no need to consider the installation error between the two springs 21. The structure is simple and easy to install, making the terminal performance safer and more stable.

[0031] In a preferred embodiment of this utility model, such as Figure 2-4The shown reed structure 2 also includes an end plate 23 connected to the side of each reed 21 away from the U-shaped plate 22. Each end plate 23 is provided with a latch 231, and the cavity wall of the mounting cavity 110 is provided with a corresponding latch hole 13. As the reed structure 2 is inserted into the mounting cavity 110, the latch 231 engages with the corresponding latch hole 13. In this application, an end plate 23 is provided at the free end of each reed 21. The end plate 23 extends outward from the corresponding reed 21 and is used to fit the inner wall of the mounting cavity 110, increasing the contact area between the entire reed structure 2 and the inner wall of the mounting cavity 110. After the spring structure 2 is inserted into the mounting cavity 110, the ends of the two springs 21 away from the U-shaped plate 22 abut against the mounting cavity 110, and the upper or lower end face of the end plate 23 abuts against the mounting cavity 110. At this time, the latches 231 on the end plate 23 engage with the corresponding latches 13 on the mounting cavity 110, thus securing the spring structure 2 and the mounting cavity 110, ensuring smoother installation of the terminal and plug and more stable performance. When the plug needs to be inserted from other sides of the terminal, simply press the latches 231 on the two springs 21 inward to disengage the latches 231 from the latches 13 and push the U-shaped plate 22 to disengage the spring structure 2 from the mounting cavity 110. Then, the spring structure 2 can be inserted into the mounting cavity 110 through the desired mounting opening. The overall structure is reasonable and easy to operate, which can effectively improve assembly efficiency and material utilization, achieving the goal of cost reduction and efficiency improvement.

[0032] In a preferred embodiment of this utility model, such as Figure 2-4 Each spring 21 shown may be V-shaped or wavy. Each spring 21 includes a protrusion 211 close to another spring 21. The two protrusions 211 arranged opposite each other together form a clamping area for engaging with the plug. Figure 2-4 The illustration only shows one V-shaped structure of the reed 21. In some embodiments, to increase the contact effect of the reed 21 or to adapt to different currents, multiple protrusions 211 can be provided on the reed 21, making the reed 21 as a whole wavy shape. Each protrusion 211 can be V-shaped or arc-shaped, preferably arc-shaped, so that two protrusions 211 form a larger contact area, which can meet the needs of large currents.

[0033] In a preferred embodiment of this utility model, such as Figure 2-4 The spring 21 shown is provided with multiple reinforcing ribs 212 on the side near the mounting cavity 110 to increase the structural strength and service life of the spring 21.

[0034] In a preferred embodiment of this utility model, such as Figure 2-4The U-shaped plate 22 shown has multiple equally spaced through holes 221, which not only reduces weight and enhances the mechanical structure of the spring structure 2, but also serves to dissipate heat. In addition, multiple heat dissipation holes are also spaced on the spring 21 to achieve the purpose of heat dissipation.

[0035] In a preferred embodiment of this utility model, such as Figure 1 , 3 The connecting part 11 shown in Figure -4 includes a base plate 111, a top plate 112, and a connecting post assembly 113. The top plate 112 is arranged parallel above the base plate 111. The connecting post assembly 113 includes multiple connecting posts 1131 connecting the base plate 111 and the top plate 112. Any two adjacent connecting posts 1131, the base plate 111, and the top plate 112 together define an installation opening. Two end plates 23 are detachably connected to the base plate 111 and the top plate 112, respectively. The base plate 111 and the top plate 112 are each provided with a locking hole 13. The base plate 111, the top plate 112, and the connecting post assembly 113 are connected to form the following configuration: Figure 1 The prism shown is preferably a quadrangular prism, a hexagonal prism, or an octagonal prism. The fixing part 12 can be connected to the base plate 111. There is an installation port between any two adjacent connecting posts 1131, which facilitates the installation of the spring structure 2 and is simple and convenient to process.

[0036] In a preferred embodiment of this utility model, such as Figure 1 , 3 As shown in Figure -4, both the base plate 111 and top plate 112 are square. There are four connecting posts 1131, two of which are integrally formed with the base plate 111 and top plate 112, while the remaining connecting posts 1131 and top plate 112 are detachably connected. Preferably, the bottom and top surfaces of the connecting portion 11 are square, and the four connecting posts 1131 form a quadrangular prism structure. The height of each connecting post 1131 is less than the length of the base plate 111, and its height is adapted to the existing plug height. Furthermore, the four connecting posts 1131 are mainly divided into two categories: the two connecting posts 1131 integrally formed with the base plate 111 and top plate 112 are the first connecting posts a, and the other two are the second connecting posts b. The distance between the two first connecting posts a is less than the distance between the two second connecting posts b. Figure 4 The two first connecting posts a shown can limit the spring structure 2. That is, as the spring structure 2 is inserted into the mounting cavity 110 between the second connecting posts b, the U-shaped plate 22 abuts against the two first connecting posts a, and the latch 231 is located just below the latch hole 13 and can be inserted into the latch hole 13 to complete the installation of the spring structure 2. The structure is simple and reasonable, easy to process, and facilitates the improvement of installation and maintenance efficiency.

[0037] In a preferred embodiment of this utility model, such as Figure 1 , 3-4 The top of the connecting post 1131 shown is provided with a limiting protrusion 1132, and the top plate 112 is provided with a limiting groove 1121 corresponding to the limiting protrusion 1132. The limiting protrusion 1132 is inserted into and engaged with the limiting groove 1121. Through the cooperation of the above structure, the top plate 112 and the corresponding connecting post 1131 can be detachably connected. The structure is simple and reasonable, and it is convenient for the installation and maintenance of the spring structure 2, saving labor and time.

[0038] In a preferred embodiment of this utility model, such as Figure 1 , 3 -4 The top plate 112 shown has a limiting block 1122 on the side near the fixing part 12 for limiting the spring structure 2. One end of the limiting block 1122 is connected to the top plate 112, and the other end is inserted into one of the mounting holes and abuts against the bottom plate 111. Figure 3 The limiting block 1122 shown is used to limit the movement of the spring structure 2. As the U-shaped plate 22 abuts against the limiting block 1122, the latch 231 is positioned just below the latch hole 13 and can be inserted into the latch hole 13, thus completing the installation of the spring structure 2. The installation of the spring structure 2 is quick and convenient, improving installation efficiency.
