[0021] A cable hole 9 is provided through the middle of the damping plate 2, a first sliding frame 10 is fixedly connected to the middle of the top of the damping plate 2, and the bottom of the first sliding frame 10 matches the outer side of the cable hole 9, a second sliding frame 11, a third sliding frame 12 and a fourth sliding frame 13 are fixedly connected to the top of the damping plate 2, and the fourth sliding frame 13 is located on one side of the first sliding frame 10, the second sliding frame 11 and the third sliding frame 12 are located on the side of the first sliding frame 10 away from the fourth sliding frame 13, and three rubber Pad 14, two rubber pads 14 are distributed at both ends of the fourth sliding frame 13, and another rubber pad 14 is located between the second sliding frame 11 and the third sliding frame 12. The three rubber pads 14 match the positions of the first fixing hole 3 and the second fixing hole 4 respectively. Bolts pass through the first fixing hole 3 and the second fixing hole 4 and are inserted into the inside of the rubber pad 14, and then the bolts are fixed in the installation position, and the top end of the rubber pad 14 is close to the bottom end of the terminal cover body 1, and the first layer of shock absorption is achieved through the high elasticity and viscosity of the rubber pad 14.

[0022] Seven dampers 15 are distributed on the shock absorbing plate 2, and springs 16 are nested on the outside of the dampers 15. A nut chuck 17 is threadedly connected to the bottom end of the damper 15. The bottom end of one nut chuck 17 is fixedly connected to the inner bottom end of the third sliding frame 12, the bottom ends of two nut chucks 17 are symmetrically fixedly connected to the inner bottom end of the second sliding frame 11, and the bottom ends of four nut chucks 17 are evenly fixedly connected to the inner bottom end of the fourth sliding frame 13. The springs 16 absorb part of the vibration energy and store it as elastic potential energy. The damper 15 gradually converts part of the stored energy into heat energy through internal mechanisms such as fluid damping, friction damping or electromagnetic damping, thereby achieving vibration attenuation and achieving the second layer of shock absorption.

[0023] The outer side of the second sliding frame 11 is slidably connected to the inner side of the second sliding groove 7, the outer side of the third sliding frame 12 is slidably connected to the inner side of the third sliding groove 8, the outer side of the fourth sliding frame 13 is slidably connected to the inner side of the first sliding groove 5, and the outer side of the first sliding frame 10 is slidably connected to the inner side of the terminal wiring groove 6. The sliding connection between the first sliding frame 10 and the terminal wiring groove 6 enables the compressor to maintain protection of the terminal wiring when vibrating.

[0024] Working principle: During use, the shock absorbing plate 2 is first placed on the bottom end of the terminal cover body 1 by external force, and the bolts are passed through the first fixing hole 3 and the second fixing hole 4 and inserted into the inside of the rubber pad 14, and then the bolts are fixed in the installation position, and the bottom end of the shock absorbing plate 2 is close to the outer end of the installation position, and the top end of the rubber pad 14 is close to the bottom end of the terminal cover body 1, and the top end of the damper 15 is close to the inner top end of the first slide groove 5, the second slide groove 7 and the third slide groove 8 respectively. When the air-conditioning compressor vibrates, the outer side of the installation position moves upward to squeeze the shock absorbing plate 2 to move upward, and the movement of the shock absorbing plate 2 squeezes the rubber pad 14 to shrink and deform. The rubber pad 14 absorbs vibrations through high elasticity and viscosity, and at the same time, the shock absorbing plate 2 drives the second sliding frame 11, the third sliding frame 12 and the fourth sliding frame The moving frame 13 moves upward and squeezes the damper 15 to contract. The damper 15 gradually converts the vibration energy into heat energy through the damping effect, thereby achieving vibration attenuation. At this time, the nut chuck 17 squeezes the spring 16 to contract. The spring 16 absorbs part of the vibration and converts it into elastic potential energy. When the outer side of the installation position moves downward, the pressure on the spring 16 disappears and begins to release the elastic potential energy to squeeze the nut chuck 17 downward. The movement of the nut chuck 17 pushes the shock-absorbing plate 2 to move downward. At the same time, the rubber pad 14 restores its initial state through its own elasticity and squeezes the shock-absorbing plate 2 to move downward and return to its initial position. When the shock-absorbing plate 2 moves up and down, the first sliding frame 10 slides inside the terminal wiring slot 6 to achieve protection of the terminal wiring at the terminal cover body 1 to prevent the circuit from being exposed to the outside.
