[0005] According to another embodiment of the utility model, further include the anti-vibration sleeve is equipped with elastic sheet.

[0006] According to another embodiment of the utility model, further include the anti-vibration sleeve is steel cover.

[0007] According to another embodiment of the utility model, further include the anti-vibration sleeve and terminal are integrally formed and fixed together.

[0008] According to another embodiment of the utility model, further include the plug main part tail end opening is fixedly connected with rear cover, and the rear cover is equipped with the perforation for passing through the terminal.

[0009] According to another embodiment of the utility model, further include the built-in sealing ring is located between the rear cover and ferrite.

[0010] According to another embodiment of the utility model, further include the rear cover is equipped with several clamping blocks, and the plug main part is equipped with several card holes for inserting clamping block.

[0011] According to another embodiment of the utility model, further include the annular groove for matching counter sealing ring is equipped on the outer wall of plug main part.

[0012] According to another embodiment of the present invention, the terminal and the anti-vibration sleeve are integrally formed.

[0013] The beneficial effects of this utility model are that it improves the waterproof performance of the connector by using a built-in sealing ring and a mating sealing ring, and improves the vibration resistance of the connector by using a vibration-damping sleeve. Attached Figure Description

[0018] Figure 1 This is an exploded view of this utility model; Figure 2 This is a cross-sectional view of the present invention.

[0019] Combined with appendix Figure 1 and attached Figure 2 As shown, a waterproof and shockproof airbag head connector includes a plug body 1, a ferrite 2, an internal sealing ring 3, a mating sealing ring 4, a terminal 5, a wire 6, and a vibration damping sleeve 7. The terminal 5 is connected to the end of the wire 6, and the vibration damping sleeve 7 is provided on the terminal 5. The terminal 5 and the vibration damping sleeve 7 pass through the ferrite 2. The terminal 5, the vibration damping sleeve 7, the ferrite 2, and the internal sealing ring 3 are all placed inside the plug body 1. The mating sealing ring 4 is installed at the end of the plug body 1.

[0020] The vibration damping sleeve 7 is equipped with a spring clip 71. The spring clip 71 can lock the terminal into the plug body 1, thereby improving the vibration resistance of the entire connector.

[0021] The vibration damping sleeve 7 is a steel sleeve.

[0022] The vibration damping sleeve 7 is integrally formed and fixed with the terminal 5, thereby improving the stability of the entire mechanism.

[0023] A rear cover 8 is fixedly connected to the opening at the tail end of the plug body 1. The rear cover 8 has a through hole for the terminal 5 to pass through.

[0024] The built-in sealing ring 3 is located between the back cover 8 and the ferrite 2.
