[0002] A PIN pin is a metal component used to complete the conductive transmission of electrical signals in a connector, and can be applied to fields such as electronics, electrical appliances, and industrial connectors. During the transmission of optoelectronic signals, a PIN pin can be used to complete the signal transmission work.

[0003] Existing technologies such as the utility model with the publication number CN220710676U disclose a new PIN pin structure, which includes a PIN pin body and a needle cylinder for installing the PIN pin body. A clamping component for fixing the PIN pin body is arranged inside the needle cylinder; the clamping component includes a clamping rod slidably connected inside the needle cylinder. A clamping groove is opened on the PIN pin body. A driving spring is arranged between the clamping rod and the needle cylinder, and the elastic force of the driving spring drives the clamping rod to be clamped in the corresponding clamping groove to fix the PIN pin body; an installation plate is arranged inside the needle cylinder, and a driving part for driving multiple clamping rods to slide out of the clamping grooves where they are located is arranged between the installation plate and the multiple clamping rods. When the PIN pin body is inserted into the needle cylinder, the elastic force of the driving spring drives the clamping rod to be clamped in the corresponding clamping groove to fix the PIN pin body, thereby improving the stability during the installation of the PIN pin body, avoiding the situation of sliding and falling of the PIN pin body, and thus improving the practicability of the PIN pin body.

[0004] The above-mentioned and existing related technologies often have the following defects: during the use of PIN pins, frequent plugging and unplugging are likely to cause wear on the surface of the PIN pins, resulting in a decrease in the contact pressure of the PIN pins and changes in their shape and size, etc., reducing the service life of the PIN pins.

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-5 , the present utility model provides a technical solution: a PIN needle for wear-resistant optoelectronic signal connection, including a PIN needle body 1. Four limiting rods 5 are slidably connected to the inner wall of the PIN needle body 1. One end of each of the four limiting rods 5 away from the PIN needle body 1 is fixedly connected to a moving arc-shaped plate 2, and the moving arc-shaped plate 2 is in close contact with the PIN needle body 1. By providing the limiting rods 5, while the moving arc-shaped plate 2 is connected to the PIN needle body 1, the moving arc-shaped plate 2 can move, and at the same time, the movement of the moving arc-shaped plate 2 can be restricted, and it is possible to avoid the deflection of the moving arc-shaped plate 2 during the movement as much as possible. By providing the moving arc-shaped plate 2, the wear during the installation of the PIN needle body 1 can be reduced.

[0031] The following specifically describes its overall specific settings and functions.

[0032] As Figures 1-5 shown, a plurality of balls 4 are installed on the side of the moving arc-shaped plate 2 away from the PIN needle body 1, and the plurality of balls 4 are all rotatably connected to the inner wall of the moving arc-shaped plate 2. The balls 4 rotatably connected to the inner wall of the moving arc-shaped plate 2 can rotate. By providing the balls 4, the wear during the installation of the PIN needle body 1 can be further reduced. A plurality of first springs 6 are fixedly connected to the side of the moving arc-shaped plate 2 away from the balls 4, and the other ends of the plurality of first springs 6 are fixedly connected to the PIN needle body 1. By providing the first springs 6, the stable connection between the moving arc-shaped plate 2 and the PIN needle body 1 can be ensured, and the position of the moving arc-shaped plate 2 can be restricted. A limiting ring 3 is slidably connected to the inner wall of the PIN needle body 1, and the side of the limiting ring 3 close to the moving arc-shaped plate 2 is an inclined surface. By providing the limiting ring 3, the position of the moving arc-shaped plate 2 can be restricted, and by providing the inclined surface of the limiting ring 3, it is convenient to move the limiting ring 3 close to the moving arc-shaped plate 2.

[0033] The surface of the limiting ring 3 is fixedly connected to a control plate 7, which is slidably connected to the inner wall of the PIN needle body 1. The control plate 7 slidably connected to the inner wall of the PIN needle body 1 can move. By moving the control plate 7, the limiting ring 3 can be conveniently controlled. The surface of the PIN needle body 1 is fixedly connected to a fixed plate 8, and the inner wall of the fixed plate 8 is slidably connected to a control rod 9, which is fixedly connected to the control plate 7. By providing the fixed plate 8, the control rod 9 can be connected to the PIN needle body 1, and by moving the control rod 9, the control plate 7 can be moved. The end of the control rod 9 away from the control plate 7 is fixedly connected to a push plate 10, and the surface of the control rod 9 is covered with a second spring 11, and the two ends of the second spring 11 are respectively fixedly connected to the fixed plate 8 and the push plate 10. By providing the push plate 10, the control rod 9 can be conveniently moved, and the second spring 11 can be conveniently installed. By providing the second spring 11, the position of the control rod 9 can be conveniently limited.

[0034] Working principle: When installing the PIN needle body 1, move the PIN needle close to the connecting part so that the PIN needle is stuck in the connecting part. During this process, the ball 4 rolls on the inner wall of the connecting part and the movable arc plate 2. At the same time, the movable arc plate 2 drives the limit rod 5 to slide on the inner wall of the PIN needle body 1. After the installation of the PIN needle is completed, push the push plate 10 to make the control rod 9 slide on the inner wall of the fixed plate 8, thereby pushing the limit ring 3 to move close to the movable arc plate 2 through the control plate 7, limiting the position of the movable arc plate 2. At this time, the second spring 11 changes from the contracted state to the normal state, thereby limiting the position of the limit ring 3. By setting the first spring 6, the movable arc plate 2 is connected to the PIN needle body 1. At the same time, the position of the movable arc plate 2 can be restricted. Space is left between the four movable arc plates 2 to ensure that the movement of the four movable arc plates 2 does not interfere with each other. By setting the limit rod 5, the movable arc plate 2 can be prevented from deflecting, which affects the movement of the movable arc plate 2. By setting the movable arc plate 2, when the PIN needle is installed, the friction loss can be reduced by moving the movable arc plate 2. Then, the limit ring 3 can be used to ensure a close connection between the movable arc plate 2 and the connecting component. At the same time, by setting the ball 4, the friction loss can be further reduced during the installation of the PIN needle, thereby improving the wear resistance of the PIN needle as much as possible and ensuring the service life of the PIN needle as much as possible.
