[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] With the rapid development and popularization of new energy vehicles, the requirements for automotive electrical systems are getting higher and higher. Electronic connectors are key components for power and signal transmission. The quality of connectors directly affects the performance of the entire electrical system. Therefore, people pay more and more attention to the reliability of electronic connectors. In the field of electronic connectors, the existing connector connection methods are generally through wave soldering or reflow soldering. Therefore, the product is not convenient enough during assembly, maintenance, and replacement.

[0022] In view of the above technical problems, the present application provides a fisheye high current terminal for automotive connectors. Figure 1 The overall structure diagram of the fisheye high current terminal of the automobile connector is shown; Figure 2 shows a schematic structural diagram of the plug portion 110; Figure 1 and Figure 2The automobile connector fisheye high current terminal includes a body 100, and the body 100 has a plug portion 110. Along the insertion direction, the plug portion 110 includes:

[0023] A connecting portion 111 connected to the main body 100;

[0024] Two groups of arc-shaped arch arms 112 are symmetrically arranged along the insertion direction and enclose a through hole, the through hole is elliptical, and the length direction of the through hole is the same as the insertion direction;

[0025] A guide portion 113, wherein one end of the guide portion 113 away from the arc-shaped arch arm 112 is designed to be conical;

[0026] After being inserted into the circuit board, the arc-shaped arch arm 112 is deformed and contacts the board hole to be fixed.

[0027] During use, the plug part 110 is inserted into the board hole of the circuit board. As the plug part 110 is inserted, the guide part 113 can form a guiding effect on the plug part 110, so as to facilitate the insertion of the plug part 110. The arcuate arch arm 112 is squeezed inward by the side wall of the board hole during insertion. At this time, the through hole is reduced, and the two groups of arcuate arch arms 112 are driven by the resetting elastic force to abut the side wall of the board hole at all times, forming an abutting friction fixation. In this application, by changing the traditional welding and adopting the plug-in method to connect with the circuit board, the terminal can be easily disassembled during assembly and maintenance.

[0028] It should be noted that in this application, there are four groups of plug parts 110, see Figure 1 However, the number is not a limitation of the present application. In some other embodiments, the plug portion 110 can also be provided with 2 groups, 5 groups, etc., which can be set as needed.

[0029] Continue to see Figure 1 On the main body 100 , there is a concave extension portion 120 between two adjacent groups of plug portions 110 .

[0030] It should be noted that in the present application, the circuit board housing is not shown, but it belongs to the prior art known to those skilled in the art and will not be described in detail.

[0031] Through the design of the extension portion 120 , the overall length of the plug portion 110 is extended laterally, so that the plug portion 110 can be inserted to the maximum extent and the insertion depth of the arc-shaped arch arm 112 is ensured.

[0032] Continue to see Figure 1 The plug portion 110 has a protruding block 130 on its surface, and one end of the block 130 extends downward in a decreasing manner and borders on the surface of the body 100 .

[0033] During use, an opening corresponding to the card block 130 is provided on the circuit board. After the main body 100 is inserted into the circuit board shell, the card block 130 is inserted into the corresponding card hole to form a limit. When the card block 130 is inserted into the shell, it can force the shell to deform, and after the docking is completed, it is inserted into the card hole to complete the fixation.

[0034] Continue to see Figure 1 The main body 100 has a protruding extrusion sheet 140 on its surface. When the main body 100 is connected to the circuit board housing, the extrusion sheet 140 is deformed and squeezes the inner wall of the housing.

[0035] During use, the extrusion sheet 140 may be slightly deformed and squeeze the inner wall of the shell, and the connection effect between the main body 100 and the shell is ensured by the friction between the extrusion sheet 140 and the inner wall of the shell.

[0036] Continue to see Figure 1 Along the docking direction between the main body 100 and the shell, the main body 100 has a protruding plug plate 150 , and the plug plate 150 has a slot 151 .

[0037] During use, the plug plate 150 is deformed in the width direction when inserted into the shell. After docking, a convex strip on the shell can be inserted into the slot 151 to form a limit, thereby further improving the fixing effect after the connection between the shell and the body.

[0038] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
