DETAILED DESCRIPTION

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a plug-in type plug-in terminal assembly, comprising a plurality of terminal bodies 1, a socket 2 is installed at the front end of the terminal body 1, a plug-in slot 3 is provided at the front end of the socket 2, two elastically deformable conductive sheets 4 are installed inside the socket 2, a support frame 5 is fixed inside the socket 2, a shell 6 is fixed at the front end of the socket 2, a plug-in port 7 is provided on the surface of the shell 6, a plug plate 8 is slidably connected inside the shell 6, a square plate 9 is fixed on the top of the plug plate 8, and a locking mechanism for locking the wire is installed inside the shell 6. By installing the locking mechanism, a stable connection can be ensured between the wire and the socket 2, and loosening or falling off of the connection caused by external vibration, impact or misoperation can be effectively prevented. This stable connection means that current or signal can be smoothly transmitted in the terminal assembly, reducing the risk of electrical failure caused by poor connection. At the same time, the locking mechanism makes it easier and faster to fix the wire after it is directly inserted into the socket 2, without the need to use additional tools or complicated operating steps, and reduces the frequency of regular inspection and maintenance, thereby reducing maintenance costs.

[0024] Reference Figure 1 - Figure 3 As shown, in this embodiment: the locking mechanism includes a transmission plate 10 fixed to the bottom of the plug plate 8, and both ends of the transmission plate 10 are slidably connected with a receiving plate 11, one end of the receiving plate 11 is fixed with a moving plate 12, and the bottom of the moving plate 12 is fixed with a clamping block 13. By pressing the square plate 9 to drive the plug plate 8 to move downward, the transmission plate 10 pushes the receiving plate 11 to drive the moving plate 12 to move in both directions, thereby driving the clamping block 13 to move together. At this time, the user can insert the wire into the socket 2 through the plug port 7, and then lock the wire through the above arrangement. The operation is simple and convenient, which improves the user's operating efficiency.

[0025] Reference Figure 1 - Figure 3 As shown, in this embodiment: fixing rods 14 are fixed on both sides of the shell 6, and a limiting groove 15 is provided on the surface of the movable plate 12. The inner cavity of the limiting groove 15 is slidably connected to the surface of the fixing rod 14. By setting the structure of the fixing rod 14 and the limiting groove 15, the moving trajectory of the movable plate 12 can be limited to avoid tilting.

[0026] Reference Figure 1 - Figure 3 As shown, in this embodiment: a return spring 16 is fixed on both sides of the shell 6, and the other end of the return spring 16 is fixed to the movable plate 12. By setting the return spring 16, the position of the movable plate 12 is limited by the force of the return spring 16 to avoid changes in the position of the movable plate 12 and affect the locking of the wire.

[0027] Reference Figure 1 - Figure 3 As shown, in this embodiment: a clamping pad 17 is provided on the inner surface of the clamping block 13. By providing the clamping pad 17 and utilizing the rubber material of the clamping pad 17, the friction between the clamping block 13 and the wire can be increased, and the wire can be protected.

[0028] Reference Figure 1 - Figure 3 As shown, in this embodiment: a slide groove 18 is opened on the top of the shell 6, and the inner wall of the slide groove 18 is slidably connected to the surface of the plug board 8. By setting the slide groove 18, the moving direction of the plug board 8 can be restricted, thereby improving the stability of the plug board 8 during movement.

[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment: travel grooves 19 are provided inside both sides of the socket 2, and travel blocks 20 are slidably connected inside the travel grooves 19. The other end of the travel block 20 is fixed to the elastic deformable conductive sheet 4. When the wire is inserted into the interior of the socket 2, the elastic deformable conductive sheet 4 is squeezed to move the elastic deformable conductive sheet 4 toward the top and bottom of the socket 2. By setting the structure of the travel grooves 19 and the travel blocks 20, the elastic deformable conductive sheet 4 can remain stable during movement to avoid deviation and affect the conductive structure.

[0030] Working principle: By installing the locking mechanism, the user can ensure a stable connection between the wire and the socket 2, and effectively prevent the connection from loosening or falling off due to external vibration, impact or misoperation. This stable connection means that the current or signal can be smoothly transmitted in the terminal assembly, reducing the risk of electrical failure due to poor connection. At the same time, the locking mechanism makes it easier and faster to fix the wire after it is directly inserted into the socket 2, without the need for additional tools or complicated operating steps, and reduces the frequency of regular inspections and maintenance, reducing maintenance costs. By pressing the square plate 9 to drive the plug plate 8 to move downward, the transmission plate 10 pushes the receiving plate 11 to drive the moving plate 12 to move in both directions, thereby driving the clamping block 13 to move together. At this time, the user can insert the wire into the socket 2 through the plug-in port 7, and then lock the wire through the above-mentioned setting. The operation is simple and convenient, which improves the user's operating efficiency. The structure of setting the fixing rod 14 and the limiting groove 15 can limit the moving trajectory of the movable plate 12 to avoid tilting. By setting the return spring 16, the position of the movable plate 12 is limited by the force of the return spring 16 to avoid the position of the movable plate 12 changing and affecting the locking of the wire. By setting the clamping pad 17 and utilizing the rubber material of the clamping pad 17, the friction between the clamping block 13 and the wire can be increased, and the wire can be protected. By setting the sliding groove 18, the moving direction of the plug board 8 can be limited to improve the stability of the plug board 8 during movement. When the wire is inserted into the inside of the socket 2, the elastic deformable conductive sheet 4 is squeezed to move the elastic deformable conductive sheet 4 toward the top and bottom of the socket 2. By setting the structure of the travel groove 19 and the travel block 20, the elastic deformable conductive sheet 4 can remain stable during movement to avoid deviation and affect the conductive structure.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
