Referring to fig. 1-5, a schematic diagram of an insulating gasket 10 with pre-installed dowel pins is shown, according to one embodiment of the present invention. The insulating gasket 10 is used to mount a first component, such as a power amplifier of a speaker, to a second component, such as a structural member of a motor vehicle body.

As shown in fig. 1 to 3, the insulating gasket 10 includes an upper gasket 11, a lower gasket 12, and a middle portion 13, and both ends of the middle portion 13 are respectively connected to the upper gasket 11 and the lower gasket 12 to form a U-shaped structure. The upper gasket 11 has an upper through hole 111, the lower gasket 12 has a lower through hole 121 aligned with the upper through hole 111, a mounting gap for accommodating at least a part of the first member is formed between the upper and

lower gaskets

11 and 12, and the lower gasket 12 is provided with a pre-tack pin 122 for fixing to the second member on a side away from the upper gasket 11.

The specific shape and size of the upper and

lower pads

11, 12 may vary depending on the specific application. For example, when the power amplifier is provided with a mounting corner, in order to facilitate the mounting of the upper pad 11 of the insulating pad 10 into the mounting corner of the power amplifier, the upper pad 11 is mostly cut out, and the remaining portion matches the shape of the mounting corner of the power amplifier. Of course, in other alternative embodiments, the upper and

lower pads

11, 12 may have the same shape and size.

When the power amplifier is used, the insulating gasket 10 is firstly installed in a part of the power amplifier, such as a mounting angle, the mounting angle enters a mounting gap between the upper gasket 11 and the lower gasket 12 and then is matched with the insulating gasket 10 to form an assembly, and at the moment, a mounting hole on the mounting angle of the power amplifier is aligned with an upper through hole and a lower through hole of the insulating gasket 10; the pre-assembly pin 122 is then secured to a second component, such as a vehicle body structural member, such that the mounting holes in the vehicle body structural member are aligned with the upper and lower through-

holes

111, 121, thereby pre-assembling the power amplifier to the vehicle body structural member (including pre-aligning the mounting holes). Then, screws are used for penetrating through the upper through hole 111, the mounting hole in the power amplifier, the lower through hole 121 and the mounting hole in the vehicle body structural part of the motor vehicle, and nuts are used for screwing, so that the power amplifier and the vehicle body structural part of the motor vehicle can be mounted.

As shown in fig. 4 to 5, the upper gasket 11 is provided with a projection for engagement with the first member on the side facing the lower gasket 12. For example, the projection is an annular flange 112 extending around the upper through hole 111 toward the lower gasket 12. When the power amplifier is mounted in the mounting gap between the upper and

lower pads

11 and 12, the annular flange 112 engages with the mounting hole on the power amplifier, thereby preventing the power amplifier from falling off.

In other alternative embodiments the lower gasket 12 is provided with a projection on the side facing the upper gasket 11 for cooperation with said first part. For example, the projection is an annular flange extending around the lower through hole 121 toward the upper gasket 11. Of course, it is also possible to provide both the upper and

lower gaskets

11 and 12 with the annular flange 112 so as to securely mount the power amplifier.

The periphery of the pin cap 1222 of the pre-pin 122 is provided with a lead-in chamfer to facilitate securing the pre-pin 122 to a structural member of the motor vehicle body. For example, a key-shaped locating hole is formed in a structural member of a motor vehicle body, which includes a circular hole and an elongated hole communicating with the circular hole, the pin cap 1222 of the pre-installed nail pin 122 is inserted through the circular hole, and then the pin 1221 slides downward along the elongated hole under the action of gravity, and the insulating gasket 10 is held in place by the pin cap 1222.

In some embodiments, the center axis of the pre-staple pin 122 is aligned with the line connecting the centers of the upper and lower through-

holes

111, 121 when viewed from the side, as shown in fig. 4-5.

In some embodiments, the upper pad 11 and/or the lower pad 12 have a thickness of 2 to 10mm, such as 3mm, and the distance between the upper pad 11 and the lower pad 12 is 2 to 10mm, such as 5 mm.

In some embodiments, the dielectric washer 10 is made of a dielectric material, such as a thermoplastic resin material. For example, the thermoplastic resin is selected from PA6 or PA 66.

In some embodiments, the dielectric washer 10 is integrally formed using a molding process.

In some embodiments, the upper pad 11 has a free end 113 remote from the intermediate portion 13, and the free end 113 of the upper pad 11 is provided with a latch portion 1131 for latching the power amplifier. When the power amplifier is mounted to the mounting gap between the upper pad 11 and the lower pad 12, the locking portions 1131 lock the power amplifier, preventing the power amplifier from falling off.

In some embodiments, lower pad 12 has a free end 123 distal from intermediate portion 13, and free end 123 of lower pad 12 is provided with a notch 1231 for preventing the first component from being inverted. The notch 1231 may prevent the power amplifier from being reversely mounted in some cases, and the power amplifier cannot enter the mounting gap between the upper pad 11 and the lower pad 12.

Alternatively or additionally, the free end 113 of the upper pad 11 is provided with a notch portion for preventing the first component from being reversely mounted, and/or the free end 123 of the lower pad 12 is provided with a locking portion for locking the power amplifier.

In some embodiments, the free end 113 of the upper pad 11 is further provided with a guide portion 1132 for guiding the power amplifier to be mounted therein, and the free end 123 of the lower pad 12 is further provided with a guide portion 1232 for guiding the power amplifier to be mounted therein. For example, the

guide portions

1132 and 1232 of the upper and

lower pads

11 and 12 may be guide slopes so as to guide the power amplifier to be inserted into the mounting gap between the upper and

lower pads

11 and 12.

In some embodiments, the upper gasket 11 is provided with a recess 114 on a side remote from the lower gasket 12. The recess 114 can increase the friction between the dielectric washer 10 and the operator's hand, facilitating the application of force when inserting and extracting the power amplifier. In other alternative embodiments, the lower gasket 12 is provided with a recess on the side remote from the upper gasket 11. Of course, the upper pad 11 and the lower pad 12 may be provided with the recessed portions at the same time.
