[0021] As shown in Figure 1 , Figure 4 , Figure 6 , Figure 7 , the surface of the terminal body 11 is provided with a fixing assembly 40, the fixing assembly 40 comprises a slot 41 opened on the surface of the terminal body 11 and an extension slot 411 penetrating through the slot 41, the side surface of the abutting block 37 is fixed with an extension plate 42, the inner wall of the slot 41 is slidingly connected with a contact block 44, a plurality of springs 43 are connected between the contact block 44 and the slot 41, and the bottom of the contact block 44 is fixed with a fixed plate 45 slidingly connected with the extension slot 411, and the contact position between the extension plate 42 and the inclined surface 46 is provided as the inclined surface 46; At the same time, when the moving plate 32 moves, the sleeve block 34 on the outer periphery of the positioning rod 321 will drive the extension plate 42 to move together; with the continuous movement of the extension plate 42, the extension plate 42 will contact the contact block 44 through the inclined surface 46 in the contact process, and the extension plate 42 will push the contact block 44 to move in the slot 41 and extrude the spring 43; With the descent of the contact block 44, the fixed plate 45 at the bottom of the contact block 44 will move in the extension slot 411, thereby fixing the insulating layer on the outer surface of the wire; such design not only deepens the fixing degree of the wire, but also effectively prevents the wire from moving; When the moving plate 32 resets, the sleeve block 34 will gradually drive the extension plate 42 to be out of contact with the contact block 44, and once the contact block 44 is no longer in contact with the extension plate 42, the spring 43 in the extruded state will rebound, push the contact block 44 and drive the fixed plate 45 to reset.

[0022] Working principle: Before connecting the wire into the terminal body 11, the insulating layer of the wire end is removed to expose the core, and then the exposed core is inserted into the terminal body 11 along the core groove 13. As the core moves deeper, it will contact the elastic conductive sheet 14 and push it to deform, so that it contacts the power supply end; At the same time, as the core moves in the core groove 13, it will gradually contact the groove 241 on the clamping rod 24, push the clamping rod 24 to rotate outward with the center rod 22 as the center, and the two ends of the clamping rod 24 move away from each other, and when rotating, it will press the first torsional spring 23. When the core pushes the elastic conductive sheet 14 to contact the power supply end, the rebound force of the first torsional spring 23 will make the two clamping rods 24 clamp the core, preventing the core from coming off the contact with the elastic conductive sheet 14, and also ensuring that the core is in the center of the core groove 13, avoiding shaking; To facilitate the adjustment of the clamping force, the moving plate 32 is pushed to slide in the limiting groove 31, and the two moving plates 32 will simultaneously drive the positioning rod 321 to move, thereby making the actuating plate 323 and the abutting block 324 move. When the abutting block 324 contacts the clamping block 33, it will move along the inclined surface thereof, drive the actuating plate 323 to rotate with the positioning rod 321 as the center and press the second torsional spring 322. After the abutting block 324 is out of contact, the second torsional spring 322 rebounds to push the actuating plate 323 to reset, so that the abutting block 324 abuts against the clamping block 33. At the same time, the movement of the positioning rod 321 will make the sleeve block 34 fixed on the outer periphery move, and the limiting block 36 sliding in the sleeve block 34 will descend along the lifting groove 35 guided by the inclined groove 312, drive the abutting block 37 to move downward and contact the clamping rod 24 which is spread out, push the clamping rod 24 to clamp the core further, preventing the core from shaking and coming off the contact; In addition, when the moving plate 32 moves, the sleeve block 34 on the outer periphery of the positioning rod 321 will drive the extension plate 42 to move, and the extension plate 42 and the contact block 44 are in contact through the inclined surface 46, push the contact block 44 to move in the slot 41 and press the spring 43. When the contact block 44 descends, the bottom fixed plate 45 moves in the extension groove 411, fixes the insulating layer of the outer surface of the wire, and deepens the fixing degree to prevent the wire from moving.

[0023] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical plug-in type terminal and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
