The outside of the sealing ring 4 is fixedly connected to the inside of the top end of the connector shell 1, and a sealing ring 2 5 is fixedly connected to the inside of the bottom end of the connector shell 1. The function of these sealing rings is to prevent pollutants such as dust and moisture from entering the inside of the shell and protect the internal components from damage. A plurality of filter holes 6 are provided inside the top end of the connector shell 1 to realize air circulation inside and outside the shell. These filter holes 6 are designed with a filtering function, which can block dust particles of a certain size and reduce pollution to internal components. Two threaded rods 7 are threadedly connected to the inside of the top end of the connector shell 1, and the far sides of the two threaded rods 7 are fixedly connected to drive caps 8, and one side of the drive cap 8 is in contact with the outside of the top end of the connector shell 1.

[0029] Reference Figure 3 and Figure 4 The adjacent sides of the two threaded rods 7 are both rotatably connected with a shock-absorbing plate 9 to help absorb and mitigate the vibration generated. A receiving hole 10 is provided inside the shock-absorbing plate 9, and a strong spring 11 is arranged inside the receiving hole 10. These springs can provide reverse pressure when the shock-absorbing plate 9 is subjected to external force, and offset part of the impact force through elastic deformation, thereby protecting the internal structure of the connector from damage. The adjacent sides of the two threaded rods 7 are both rotatably connected with a limiting plate 12. The function of the limiting plate 12 is to limit the expansion and contraction range of the spring, prevent the spring from escaping from the receiving hole 10 or being over-compressed, and ensure the stability and reliability of shock absorption. The outer side of the limiting plate 12 is slidably connected to the inside of the receiving hole 10, one end of the strong spring 11 is fixedly connected to one side of the limiting plate 12, and the other end of the strong spring 11 is fixedly connected to one side of the inner side of the receiving hole 10.

In addition, the material of the sealing ring has a certain degree of elasticity, which not only enhances the sealing performance, but also provides an additional fixing effect and enhances the stability of the structure. During the operation of the equipment, the inverter will vibrate. At this time, the staff can manually twist the drive cap 8. The design of the drive cap 8 allows the user to easily adjust it. This adjustment drives the threaded rod 7 and the rotation connection therewith. The damping plate 9 moves, so as to fix the inverter more firmly. A receiving hole 10 is provided inside the damping plate 9. A strong spring 11 is installed in the receiving hole 10. These springs can provide reverse support force when the inverter vibrates, effectively reduce the vibration generated by the inverter, reduce equipment wear, and extend the service life. The heat generated by the equipment during operation needs to be effectively handled. A plurality of filter holes 6 are provided inside the top of the connector housing 1. These filter holes 6 allow internal heat to be discharged while blocking external dust particles from entering, keeping the interior clean. This filtering and heat dissipation design ensures that the equipment maintains internal cleanliness and cooling while working at high efficiency.
