[0007] As a preferred technical solution, the connecting member includes a first stud, a second stud and a rotating block. The rotating block is installed between the first stud and the second stud. The rotating block is arranged in a hexagonal structure. The first stud is threadedly connected to the fixing ring and extends upward to be inserted into the positioning groove below. The second stud extends through the installation groove to the outside.

[0008] As a preferred technical solution, the top surface of the U-shaped plate is flush with the top surface of the insulating gasket, the bottom surface of the U-shaped plate is hidden in the installation groove, and the outer ring surface of the U-shaped plate is parallel to the outer ring surface of the insulating gasket.

[0009] As a preferred technical solution, the U-shaped plate is made of insulating plastic material.

[0010] As a preferred technical solution, the fixing ring is made of metal material.

[0011] The beneficial effects of the utility model are as follows: the utility model has a simple structure, the U-shaped plate can be sleeved in the installation groove, and after the connecting piece and the acceleration sensor are installed on the U-shaped plate, the positioning between the U-shaped plate and the insulating gasket can be achieved, thereby increasing the stability of the U-shaped plate after installation, and the second stud on the connecting piece can be threadedly connected to the device under test to increase the connection firmness with the device under test, and the installation and disassembly are convenient, and isolation can be achieved through the insulating gasket and the U-shaped plate.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an insulating gasket and acceleration sensor assembly of the utility model includes an insulating gasket 1, an acceleration sensor 2 and a connector, the insulating gasket 1 is provided with a mounting groove 5 of a "U"-shaped structure on the outside, a U-shaped plate 3 for fixing the connector and the acceleration sensor 2 is provided in the mounting groove 5, mounting holes are provided on the top and bottom surfaces of the U-shaped plate 3, fixing rings 4 are installed in the mounting holes, and one end of the accelerator sensor and the connector are installed in the fixing ring 4.

[0022] In this embodiment, positioning grooves 8 are provided on the top and bottom surfaces of the installation groove 5 opposite to the fixing ring 4, and one end of the acceleration sensor 2 protrudes toward the insulating gasket 1 to form a positioning portion 9, and the positioning portion 9 is inserted into the positioning groove 8, and a threaded connection is arranged between the acceleration sensor 2 and the fixing ring 4.

[0023] In this embodiment, the connecting member includes a first stud 10, a second stud 6 and a rotating block 7. The rotating block 7 is installed between the first stud 10 and the second stud 6. The rotating block 7 is arranged in a hexagonal structure. The first stud 10 is threadedly connected to the fixing ring 4 and extends upward to be inserted into the positioning groove 8 below. The second stud 6 passes through the installation groove 5 and extends to the outside.
