[0020] The present invention provides Figure 1-Figure 10 A terminal for an air-conditioning compressor of a new energy vehicle with an insulating protection device is shown, comprising a shell 1, a plurality of through holes arranged in a circular array are provided on the top of the shell 1, a plurality of terminal blocks 2 are provided in the through holes, a plurality of through holes are provided with mutually connected strip grooves, and the adjacent ends of the plurality of strip grooves are commonly connected with a circular groove, and the circular groove is provided at the center of the top of the shell 1; the terminal block 2 comprises a column 21 and a limiting disk 22, the column 21 passes through the inner cavity of the adjacent through hole, a plurality of limiting disks 22 are provided, and the plurality of limiting disks 22 are arranged in a circular shape on the outer wall of the column 21, a shock-absorbing component 23 is sleeved on the outer wall of the limiting disk 22, an opening is provided on the shock-absorbing component 23 to cooperate with the plurality of limiting disks 22, and one end of the shock-absorbing component 23 is connected in the through hole; this structural design makes the layout of the components of the terminal block more reasonable, which is conducive to the realization of various functions, and the through holes arranged in a circular array and the related connection structure facilitate the installation and line connection of the terminal block 2, thereby improving the overall assembly convenience and stability.

[0021] Furthermore, two detachable insulating sleeves 211 are symmetrically provided on the outer wall of the column 21, and the two insulating sleeves 211 are fitted with the shock-absorbing assembly 23. One end of the column 21 is connected to an external connecting piece 212, and the other end of the column 21 is connected to an internal connecting piece 213. The detachable insulating sleeve 211 is convenient for installation and maintenance, and can effectively ensure the insulation performance of the column 21. The setting of the external connecting piece 212 and the internal connecting piece 213 facilitates connection with external and internal circuits, thereby enhancing the versatility and functionality of the terminal.

[0022] Furthermore, the shock-absorbing assembly 23 includes a sleeve 231, the top of which is provided with a plurality of mounting grooves that cooperate with the limiting disk 22, a silicone layer 232 is fitted on the inner wall of the sleeve 231, a glass body 233 is provided in the silicone layer 232, and the glass body 233 is sleeved on the outer wall of the limiting disk 22; a mounting plate 234 is provided on the side wall of the sleeve 231, and the mounting plate 234 is mounted on the shell 1 by bolts; the matching structure of the sleeve 231 and the limiting disk 22 ensures the stability of the connection, the silicone layer 232 and the glass body 233 can effectively buffer vibration and reduce the impact of vibration on the internal structure, and the mounting plate 234 installed by bolts facilitates the connection and disassembly of the shock-absorbing assembly 23 and the shell 1, which is conducive to maintenance and replacement.

[0023] Furthermore, a cross-shaped incision is opened on the silicone layer 232; the cross-shaped incision can further enhance the elasticity and deformation ability of the silicone layer 232, better absorb and disperse vibration energy, and improve the shock absorption effect, while not affecting its overall structural strength and stability, and making the installation process easier.

[0024] Furthermore, an annular groove cooperating with the mounting plate 234 is opened at the top of the through hole, and the seismic absorption component 23 is connected in the annular groove by bolts; the cooperation between the annular groove and the mounting plate 234 makes the installation of the seismic absorption component 23 more precise, and the bolt connection in the annular groove enhances the reliability of the connection, avoids the displacement of the seismic absorption component 23 during the vibration of the vehicle, and ensures the stability of the overall structure.

[0025] Furthermore, a limiting ring is provided at the bottom of the shell 1, and a threaded groove cooperating with the limiting ring is opened on the inner bottom wall of the shell 1; the cooperation between the limiting ring and the threaded groove facilitates the installation and positioning of the shell 1 and other components, improves the accuracy and firmness of the overall installation, prevents the shell 1 from shaking or shifting during use, and ensures the normal operation of the terminal.

[0026] Furthermore, a welding seam is provided on one side of the insulating sleeve 211 close to the column 21; the existence of the welding seam makes the connection between the insulating sleeve 211 and the column 21 tighter, enhances the fixing effect of the insulating sleeve 211, prevents the insulating sleeve 211 from loosening or falling off during long-term use, and ensures the durability and reliability of the insulation performance.

[0027] Working principle: Installation steps: The first step is to place the limiting plate 22 into the ferrule 231 so that the position of the installation slot is aligned with the position of the installation slot on the ferrule 231. At this time, the limiting plate 22 is rotated to make the installation slot empty. In the second step, the personnel pour the heated epoxy resin potting glue into the circular groove, and the liquid epoxy resin potting glue flows to the top of the multiple terminal 2 through the strip groove, and flows into the ferrule 231 through the installation groove for filling, and after curing, the top of the terminal 2 is sealed and insulated; It should be noted that after the column 21 and the ferrule 231 are installed, the insulating sleeve 211 is installed so that the insulating sleeve 211 is inserted between the ferrule 231 and the column 21 to isolate vibration conduction; Shock absorption principle: When the vehicle is running, the vibration of running is transmitted to the mounting plate 234 and the ferrule 231 through the shell 1 connected to the compressor shell. When the force of vibration is transmitted to the insulating sleeve 211 and the silicone layer 232, since the insulating sleeve 211 and the silicone layer 232 are both made of silicone material, the force of vibration can be weakened. Due to the traditional installation method, the vibration is directly transmitted through the hard material, the vibration force is large, and the transmission speed is fast. Under the influence of long-term vibration, the ceramic coating will have cracks and damage. The epoxy resin potting glue located at the top of the shock-absorbing component 23 for sealing is subject to less vibration force, which reduces the transmission of vibration, increases the service life of the epoxy resin potting glue, reduces the problem of surface damage caused by vibration, and improves the sealing.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
