[0026] Example 1 This embodiment provides an auxiliary assembly device for power connectors, such as... Figure 1 and Figure 5 As shown, it includes a first clamping plate 1, a first fixing plate 2, a second clamping plate 3, and a second fixing plate 4; the first clamping plate 1 is fixedly connected to the first fixing plate 2, and the second clamping plate 3 is fixedly connected to the second fixing plate 4; the first clamping plate 1 and the second clamping plate 3 have a symmetrical structure, and after installation, they form a U-shaped structure, which is used to accommodate the plug base; a clamping plate spring cavity 5 is provided at the bottom of the U-shape, and the clamping plate spring cavity 5 is located between the first clamping plate 1 and the second clamping plate 3; there are two clamping plate spring cavities 5, each accommodating a clamping plate spring 6.

[0027] It also includes guide post cavities 7, which are located at the bottom of the entire device. There are two guide post cavities 7. Each guide post cavity 7 passes through the first fixing plate 2, the first clamping plate 1, the clamping plate spring cavity 5, the second clamping plate 3, and the second fixing plate 4 in sequence. Each guide post cavity 7 is used to accommodate a guide post 8. The guide post 8 is connected to the locking handle 10 through the connecting shaft 9. The locking handle 10 moves to drive the clamping plate spring 6 to extend or compress.

[0028] In a specific embodiment, the first clamping plate 1 is provided with a first ejector cavity 11 for accommodating the first ejector 12, the second clamping plate 3 is provided with a second ejector cavity 13 for accommodating the second ejector 14; the first fixing plate 2 is provided with a first ejector spring cavity 15 for accommodating the first ejector spring 16; the second fixing plate 4 is provided with a second ejector spring cavity 17 for accommodating the second ejector spring 18.

[0029] When the device is working, the first ejector spring cavity 15 corresponds to the first ejector cavity 11, and the second ejector spring cavity 17 corresponds to the second ejector cavity 13; the first ejector 12 and the second ejector 14 press against the insertion hole assembly 24 inward under the action of the first ejector spring 16 and the second ejector spring 18, respectively.

[0030] In a specific implementation, the first clamping plate 1 is fixed to the first fixing plate 2, and the second clamping plate 3 is fixed to the second fixing plate 4 in the same way. This embodiment will be described using the method of fixing the first clamping plate 1 to the first fixing plate 2 as an example: The first clamping plate 1 and the first fixing plate 2 are respectively provided with a first fixing cavity and a second fixing cavity at corresponding positions on the top. The first fixing cavity and the second fixing cavity are connected to form a locking cavity. The locking screw 19 can be tightened into the locking cavity to realize the fixed installation of the first clamping plate 1 and the first fixing plate 2.

[0031] Furthermore, the second fixing cavity of the first fixing plate 2 is specially provided with a space that can accommodate the nut of the locking screw 19, so that the locking screw 19 can be completely located inside the first fixing plate 2 after being fixed, leaving room for the rotation of the rotating handle, preventing the rotating handle from not moving properly and affecting the overall working effect of the device.

[0032] In a specific implementation, a circular hole 81 is provided at one end of the guide post 8. The guide post 8 is inserted from one side of the guide post cavity 7 and inserted from the other side, exposing the circular hole 81. The connecting shaft 9 first passes through the circular hole 81 of one guide post 8, then through the circular hole 81 of the locking handle 10, and finally through the circular hole 81 of another guide post 8.

[0033] Furthermore, the guide post 8 includes a post body 83 and a guide post cap 82. One end of the post body 83 has a round hole 81, and the other end is fixed with the guide post cap 82 to form the guide post 8.

[0034] Furthermore, guide post cavity 7 is provided with guide post cap cavities at both ends. The guide post cap cavities can completely accommodate the guide post caps, so that the guide post caps are completely located inside the fixing plate. The post 83 can penetrate the entire guide post cavity 7, but due to the presence of the guide post caps, the guide post caps cannot pass through the guide post cap cavities.

[0035] Furthermore, the locking handle 10 and the connecting shaft 9 are rotatably connected, and it has two working states. In the two working states, the distance from the rotation axis of the locking handle 10 to the first fixed plate 2 is different, so the clamping spring 6 can be compressed or extended. Specifically: like Figure 3 As shown, in working state 1: rotate the handle until the flat surface of the handle touches the first fixed plate 2. At this time, the distance from the handle shaft to the first fixed plate 2 is the first distance. The guide post 8 is pulled tight along the guide post cavity 7 by the rotating handle. Due to the action of the guide post 8 cap, the guide post 8 will drive the first clamping plate 1 and the second clamping plate 3 to clamp together. The clamping plate spring 6 is compressed, and the U-shaped structure can clamp and fix the first base 21.

[0036] like Figure 2 As shown, in working state 2: rotate the handle until the direction of the handle is parallel to the direction of the guide post 8. At this time, the distance from the axis of the handle to the first fixed plate 2 is the second distance. The second distance is less than the first distance. The guide post 8 is relaxed by rotating the handle, the compressed clamp spring 6 extends freely, the first clamp 1 and the second clamp 3 separate under the action of the clamp spring 6, the U-shaped structure is relaxed, and the first base 21 can be freely removed and placed.

[0037] In a specific implementation, the first ejector pin 12 and the first ejector pin 12 spring, and the second ejector pin 14 and the second ejector pin 14 spring are fixed in the same way. In this embodiment, the first ejector pin 12 and the first ejector pin 12 spring are used as an example for explanation.

[0038] The first ejector pin 12 includes a needle body and an ejector pin cap, which are fixedly connected to the needle body to form the first ejector pin 12. The first ejector pin 12 spring is installed in the first ejector pin spring cavity 15, and the ejector pin cap is in contact with the ejector pin spring. The ejector pin cap is located in the first ejector pin spring cavity, and the needle body is located in the first ejector pin cavity 11. The size of the first ejector pin cavity 11 is smaller than the size of the first ejector pin spring cavity 15, so the ejector pin cap cannot enter the first ejector pin cavity 11, but the needle body can enter the first ejector pin spring cavity 15.

[0039] Furthermore, when the device is working, the socket assembly 24 will press the first pin 12 and the second pin 14 during the installation process. The first pin 12 transmits pressure along the pin body towards the pin cap, and the spring of the first pin 12 is compressed. When the socket assembly 24 is installed in place, the pressure decreases, the pins on both sides move towards the middle, the spring of the first pin 12 extends, and the socket assembly 24 is locked and fixed by the pins on both sides to prevent the short-circuit spring 20 from popping the socket assembly 24 out of the plug.

[0040] Working principle of this utility model: like Figure 5 As shown, loosen the locking handle 10 to separate the first clamping plate 1 and the second clamping plate 3 under the elastic force of the clamping spring 6. Place the first base 21 to be assembled into the first base 21, and lock the locking handle 10 to fix the first base 21. Then, install the shorting spring 20 and the shorting device 23 into the first base 21 in sequence. Simultaneously, insert the two side socket assemblies 24 into the first base 21. When the socket assembly 24 is pressed down, the first ejector pin 12 and the second ejector pin 14 on both sides of the device passively retract to their respective ejector pin spring chambers. When the socket assembly 24 is pressed into place, the two ejector pins are directly facing the threaded holes of the socket assembly 24. Under the action of the ejector pin springs on both sides, the ejector pins on both sides pop out, locking and fixing the socket assembly 24 so that it cannot be popped open by the short-circuit spring 20. After all assembly is completed, remove the second base 22, loosen the locking handle 10, and take out the assembled plug to complete the assembly.

[0041] This utility model can assist in plug assembly, simplify plug assembly steps, prevent the plug socket assembly 24 from popping out due to the elastic force of the short-circuit spring 20 during plug socket assembly, and improve assembly efficiency.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the 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.
