This method will cause the stress on the small busbar to be concentrated and directly apply a relatively concentrated force to the small busbar, thereby causing deformation of the small busbar and a decrease in its service life. Therefore, an AC / DC small busbar installation mechanism is proposed. Summary of the Invention

[0070] The implementation manner is specifically as follows: Place the clamping member 200 on both sides of the installation groove 105, then place the busbar trunk body 500 between the two installation grooves 105, and then insert the plug-in assembly 300 into the sliding cavity 102. By knocking on the knocking table 302, the sliding seat 301 continuously moves in the sliding cavity 102. During this process, the self-locking piece 305 makes the plug-in assembly 300 be unidirectionally locked in the sliding cavity 102 and unable to retreat. After the sliding seat 301 drives the self-locking piece 305 to insert into the sliding cavity 102, if the sliding seat 301 retreats out of the sliding cavity 102, it will cause the self-locking piece 305 to swing and tend to become in a vertical state, and the space provided by the sliding cavity 102 and the connecting groove 303 is not enough for it to stand vertically, thus resulting in locking.

[0071] During this period, the V-shaped plate 307 abuts against and pushes the abutting block 203 to move, so that the abutting block 203 drives the clamping plate 201 to approach and lock the busbar trunk body 500. Connect the fixing mechanism 400 to the bottom end of the main body assembly 100, and then lock the connecting arm two 407 on the object to be fixed through the U-shaped hoop 409 and the connecting arm three 408, so as to fix the main body assembly 100 and the busbar trunk body 500.

[0072] It should be understood that in the development process of any actual implementation manner, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing, and production.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
