Detailed implementation manners
[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0032] Please refer to Figures 1-4 , the present invention provides the following technical solutions: An anti - detachment mechanism for a plug - in terminal, comprising: an anti - detachment bottom plate 1, a first rubber pad 2, an ear plate 3, a sleeve 4, a connecting column 5, a limiting piece 6, a spring 7, a clamping plate 8, a second rubber pad 9, a connecting plate 10, an anti - detachment cover 11, a threaded rod 12, a connecting ring 13, a lower pressing plate 14, a third rubber pad 15, a telescopic rod 16, and a wire insertion port 17;
[0033] When using the anti - detachment mechanism for the plug - in terminal, as Figure 1 shown, first insert the plug - in terminal through the wire insertion port 17 on one side of the anti - detachment cover 11, then insert the connection terminal through the wire insertion port 17 on the other side of the anti - detachment cover 11, and then insert the plug - in terminal onto the connection terminal. At this time, the plug - in terminal and the connection terminal are initially butted together, but the plug - in terminal and the connection terminal may still become loose due to external forces;
[0034] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the anti-disconnection cover 11 is installed on the upper side of the anti-disconnection bottom plate 1, and the mounting holes on the ear plate 3 are aligned with the mounting holes on the anti-disconnection bottom plate 1. The anti-disconnection bottom plate 1 and the anti-disconnection cover 11 are fixedly connected together by bolts. During the connection process of the anti-disconnection cover 11 and the anti-disconnection bottom plate 1, the clamping plate 8 under the inner connecting plate 10 of the anti-disconnection cover 11 will move downward, squeezing the lead wire at the clamping plate 8 fixedly installed on the upper side of the anti-disconnection bottom plate 1. And a second rubber pad 9 is provided on one side of the clamping plate 8. The second rubber pad 9 can prevent the lead wire from directly contacting the clamping plate 8, which may cause the clamping plate 8 to be damaged. In addition, the other side of the clamping plate 8 is fixedly connected to one side of the connecting column 5. The connecting column 5 is slidably connected to the sleeve 4, and a limiting piece 6 is provided at the other end of the connecting column 5. A spring 7 is provided between the sleeve 4 and the limiting piece 6. The clamping plate 8 is squeezed by the lead wire and the opposite clamping plate 8, causing the spring 7 in the respective corresponding sleeve 4 to undergo elastic deformation. Thus, the lead wire on the plug-in terminal is fixed by the clamping plate 8, preventing the connection between the lead wire and the terminal from being damaged due to external force, resulting in poor contact. In addition, the limiting piece 6 plays a role in limiting the connecting column 5, preventing the connecting column 5 from directly popping out of the sleeve 4 due to the spring 7 restoring elastic deformation after the anti-disconnection cover 11 is disconnected from the anti-disconnection bottom plate 1, playing a protective role. Finally, the lead wires of the plug-in terminal and the wiring terminal are fixed by the clamping plate 8, playing an anti-disconnection role;
[0035] As Figure 1 and Figure 2 shown in the figure, after the anti-disconnection cover 11 is fixed on the upper side of the anti-disconnection bottom plate 1, the plug-in terminal will still shake between the anti-disconnection bottom plate 1 and the anti-disconnection cover 11. Since the threaded rod 12 is threadedly connected to the anti-disconnection cover 11, and the lower end of the threaded rod 12 is fixedly connected to the connecting ring 13, and the threaded rod 12 is rotatably connected to the lower pressing plate 14 through the connecting ring 13, the rotation of the threaded rod 12 will cause the lower pressing plate 14 to move downward, so that the plug-in terminal is clamped between the anti-disconnection bottom plate 1 and the lower pressing plate 14. In addition, a telescopic rod 16 is provided on the upper side of the threaded rod 12. The telescopic rods 16 symmetrically arranged about the vertical central axis of the lower pressing plate 14 can play a role in limiting the lower pressing plate 14, preventing the lower pressing plate 14 from rotating during the downward movement, resulting in the disconnection of the plug-in terminal due to the rotation of the lower pressing plate 14. During the up and down movement of the lower pressing plate 14, the telescopic rod 16 will expand and contract accordingly. In addition, the threaded rods 12 symmetrically arranged about the vertical central axis of the anti-disconnection cover 11 can respectively clamp the plug-in terminal and the wiring terminal, fixing them between the anti-disconnection bottom plate 1 and the lower pressing plate 14. In addition, the third rubber pad 15 on the lower side of the lower pressing plate 14 and the first rubber pad 2 on the upper side of the anti-disconnection bottom plate 1 can play a protective role for the plug-in terminal, preventing the plug-in terminal from being squeezed and damaged.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
