[0034] like Figures 1-3 As shown, this embodiment of the present invention provides a high-voltage connector terminal structure, including a main body 1 and a spring 2. The main body 1 includes two oppositely arranged plug plates 11, with a slot 12 formed between the two plug plates 11. The spring 2 includes a main plate 21, with a plurality of circumferentially distributed spring contacts 22 in the middle of the main plate 21. The main plate 21 is located in the slot 12 and is fixedly connected to the plug plates 11.

[0035] like Figure 4 , Figure 5 As shown, the high-voltage connector terminal structure provided in this embodiment of the present invention has a spring 2 with a centrally radial shape, which makes the spring 2 non-directional. This allows the plug 4 to be inserted into the slot 11 from multiple directions and make good contact with each spring 22. It can be matched with a variety of connectors (adapted to connectors with different insertion directions) and can also connect multiple connector plugs, improving the convenience of use.

[0036] like Figures 1-3 As shown, in order to achieve a fixed connection between the spring 2 and the plug plate 11, in one embodiment of the present invention, the main board 21 of the spring 2 and the plug plate 11 are provided with corresponding riveting holes to facilitate riveting of the two.

[0037] like Figure 3As shown, in one embodiment of this utility model, the motherboard 21 has a circular hole 23 in the middle, and one end of the spring piece 22 extends from the circumference of the circular hole 23 to the center of the circular hole 23. Further, to improve the connection stability with the plug in the insertion slot 11 and prevent loose connections, the end of the spring piece 22 is higher than the surface of the motherboard 21, so that when the two contact, the end of the spring piece 22 maintains pressure towards the plug under the action of elastic force. Even further, to improve the connection stability with the plug in the insertion slot 11 and prevent loose connections caused by uneven plug surfaces, adjacent spring pieces 22 have different lengths, making multiple spring pieces 22 serrated, increasing the area covered by the ends of the spring pieces 22.

[0038] Furthermore, such as Figure 1 As shown, in order to ensure good contact between the spring 22 and the plug in the insertion slot 11, in one embodiment of this utility model, there are two springs 2, and the two springs 2 are respectively fixedly connected to the two plug plates 11. The two springs 2 are arranged opposite to each other, and both sides of the plug in the insertion slot 11 are in contact with the spring 22 of the spring, which greatly improves the stability of the connection.

[0039] To securely connect the two plug plates 11, in one embodiment of this invention, the edges of the two plug plates 11 are connected by several connecting structures, with adjacent connecting structures forming sockets. A plug can be inserted into the slot 11 from between the sockets and contact the spring contact 22 of the spring 2. For example... Figure 1 , Figure 2 As shown, in this embodiment, the plug-in plate 11 is rectangular, and connecting structures are provided at its four corners, forming three sockets (the remaining socket is for cable connection), allowing the plug to be inserted into the slot 11 from a 90-degree or 180-degree angle. Preferably, all sockets have the same width, for example, 12.2 mm, to standardize the interface and facilitate plug insertion. In this embodiment, the connecting structure is a connecting post 13, which extends from one edge of the plug-in plate 11 towards another plug-in plate 11, and the connecting post 13 has a positioning hole 131. The other plug-in plate 11 has a positioning pin 132 corresponding to the positioning hole 131. In other embodiments, the two plug-in plates 11 can also be connected by other detachable methods, such as bolt connection, snap-fit ​​connection, etc.

[0040] like Figure 1 , Figure 2As shown, for connection with a cable, one end of the plug plate 11 extends outward and is provided with a cable connection portion 3. In one embodiment of the present invention, the cable connection portion 3 is crimped with a cable (not shown in the figure), which includes a cable core crimping plate 31 and a cable sheath crimping plate 32. The cable core crimping plate 31 is crimped with the cable core of the cable, and the cable sheath crimping plate 32 is crimped with the cable sheath of the cable.

[0041] like Figure 6 As shown, in another embodiment of this invention, the cable connector 3 is welded to the cable core of a cable (not shown). Preferably, the cable connector 3 is ultrasonically welded to the cable core to provide excellent electrical performance.

[0042] This utility model also provides a high-voltage connector, including the high-voltage connector terminal structure described above.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
