[0031] Specifically, when the plug-in 4 is inserted into the device body 1, the guide block 205 on the side of the plug-in 4 slides along the inside of the device body 1 to provide a stable insertion path for the plug-in 4, ensuring that the plug-in 4 can be accurately and correctly inserted. As the plug-in 4 continues to penetrate, the fixing block 204 will be extruded by the guide block 205, causing the second spring 202 to contract. When the fixing groove 206 on the guide block 205 gradually aligns with the fixing block 204 of the locking mechanism 2 inside the device body 1, the second spring 202 rebounds, pushing the connecting plate 203 to slide the fixing block 204 downward and embed it into the fixing groove 206, completing the firm locking of the plug-in 4 and the device body 1, effectively preventing the plug-in 4 from accidentally falling off during use. The pin 9 is sleeved in the limiting tube 11, making the pin 9 contact with the power ring 10 to achieve electrical connection. The limiting tube 11 simultaneously plays a positioning and protection role for the pin 9, ensuring accurate and stable connection and reliable connection between the pin 9 and the wire 5.

[0032] When it is necessary to separate the plug-in 4 and the device body 1, the unlocking block 201 is pulled upward to slide on the upper end of the device body 1, causing the connecting plate 203 to simultaneously drive the fixing block 204 to move upward. At this time, the second spring 202 will be extruded by the connecting plate 203, storing elastic potential energy, and at the same time, the fixing block 204 gradually disengages from the fixing groove 206, releasing the lock. After that, the plug-in 4 can be easily pulled out from the inside of the device body 1. The entire operation process is simple and fast, improving the installation and disassembly efficiency and facilitating the maintenance and repair of the equipment.

[0033] Referring to Figures 1-6 , the plug-in 4 is internally provided with a wire clamping mechanism 7.

[0034] Specifically, when installing the wire 5 inside the plug-in 4, first pull the top plate 3 to make it rotate around the hinge point, and the rotation of the top plate 3 will cause the limiting ball 6 to be extruded, so that it slides inside the plug-in 4 and compresses the first spring 8 to make it shrink, when the clamping relationship between the limiting ball 6 and the top plate 3 is released, the top plate 3 is opened smoothly, creating space for the installation of the wire 5, at this time, the outside of the wire 5 is aligned with the first clamping groove 701 on one side of the plug-in 4, then it is pushed down, so that the wire 5 slides along the inner wall of the clamping groove, the wire 5 has a certain elasticity, when it is completely embedded in the first clamping groove 701, the wire 5 is embedded in the third clamping groove 706 and the second clamping groove 705 in turn, so that the wire 5 is in a curved state inside the plug-in 4, the multiple clamping grooves not only enhance the stability of the installation of the wire 5, prevent the wire 5 from falling off, but also simplify the installation steps and reduce the operation difficulty;

[0035] When the wire 5 is pulled by external force, the sliding block 703 will slide inside the plug-in 4 and extrude the compression spring 702, the reverse elastic force generated by the compression spring 702 increases the resistance of the wire 5 being pulled, so that the wire 5 can withstand greater pulling force, improving the tensile performance of the wire 5, effectively avoiding the problem of loose or connection failure of the wire 5 caused by external force pulling, and ensuring the reliability of electrical connection;

[0036] The anti-interference coating covering the outside of the wire 5 can efficiently block external electromagnetic interference signals and prevent them from interfering with the signal transmission of the wire 5, ensuring the purity of signal transmission, at the same time, the device main body 1 is also coated with an anti-interference coating, which cooperates with the anti-interference coating of the wire 5 to reduce electromagnetic leakage in the signal transmission process from the inside and outside, forming a comprehensive anti-interference protection system, this double protection design improves the overall anti-interference performance, meets the demand of application scenarios with high requirements for signal stability and accuracy, the anti-interference coating mainly realizes anti-interference effect from the aspects of electromagnetic shielding and absorption, it adopts conductive polymer coating technology and nano composite material technology, which is a mature and public technology in the prior art, therefore, the specific structure and working principle of the anti-interference coating will not be described here.

[0037] Working principle: when the plug-in 4 is needed to be inserted into the device body 1, the guide block 205 plays a guiding role by sliding along one side of the device body 1, ensuring that the plug-in 4 is accurately inserted, and as the plug-in 4 goes deeper, the fixed slot 206 on the guide block 205 will gradually align with the fixed block 204, at which time, under the elastic force of the second spring 202, the connecting plate 203 drives the fixed block 204 to slide downward and embed into the upper end of the fixed slot 206, thereby realizing the locking connection of the plug-in 4 and the device body 1, preventing the plug-in 4 from accidentally falling off, if the plug-in 4 and the device body 1 need to be separated, the unlocking block 201 is pulled upward, so that the connecting plate 203 drives the fixed block 204 to move upward, the upward movement of the connecting plate 203 not only extrudes the second spring 202, making it shrink, but also makes the fixed block 204 gradually separate from the fixed slot 206, then the plug-in 4 can be pulled out from the inside of the device body 1, the pin 9 is sleeved in the limiting tube 11, realizing electrical connection, and at the same time the limiting tube 11 also plays a positioning and protection role for the pin 9, ensuring the accuracy and stability of the connection, so that the pin 9 is connected with the wire 5;

[0038] When the wire 5 is put into the plug-in 4, the top plate 3 is first pulled to make it rotate, prompting the limiting ball 6 to slide in the plug-in 4 and extruding the first spring 8, so that it shrinks in the plug-in 4, and then the connection between the limiting ball 6 and the top plate 3 is released, so as to open the top plate 3, then the wire 5 is put in, and its outside is aligned with the first clamping groove 701, then it is pushed downward to make it slide in the first clamping groove 701, and finally it is embedded in the first clamping groove 701, then the wire 5 is clamped into the third clamping groove 706 and the second clamping groove 705 in turn, not only making the wire 5 not easy to fall off, but also making the installation of the wire 5 convenient, when the wire 5 is pulled, the sliding block 703 will slide in the plug-in 4 and extrude the plurality of compression springs 702, so that they shrink in the plug-in 4, and the plurality of compression springs 702 make the pulling of the wire 5 more laborious, thereby improving the tensile strength of the wire 5.
