Description

Technical Field

[0001] The utility model relates to the technical field of protective caps, in particular to a dustproof protective cap for a wiring harness plug support of an air spring assembly. Background Art

[0002] The wiring harness plug support of the air spring assembly is an important component in the air spring system. It is threadedly connected to the top of the piston rod and is mainly used to fix and support the wiring harness plug to ensure the stability and reliability of the wiring harness connection. The wiring harness plug support is mostly made of metal or high-strength plastic materials. Its shape and design must be coordinated with other parts of the air spring (such as airbags, pistons, etc.) to ensure that no interference or damage occurs during installation and use. The wiring harness plug support is provided with an interface for connecting the wiring harness plug. The interface adopts a standardized design to facilitate matching with different types of wiring harness plugs.

[0003] Currently, before being installed in the air spring assembly, the wiring harness plug support must go through a transportation process from the sub-component factory to the final assembly factory. However, during this transportation process, the interface of the wiring harness plug support is extremely susceptible to the invasion of external contaminants (such as moisture or dust). The entry of such contaminants often causes poor contact or even damage to the wiring harness plug support, thus affecting its normal use. Utility Model Content

[0004] The purpose of the utility model is to provide a dustproof protective cap for a wiring harness plug support of an air spring assembly, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a dustproof protective cap for a wiring harness plug support of an air spring assembly, comprising a wiring harness plug support, a protective cap installed at the interface of the wiring harness plug support, the protective cap comprising a cap body covering the interface of the wiring harness plug support and a cylindrical boss plugged into the interface of the wiring harness plug support, a paddle being integrally provided at one end of the cap body away from the wiring harness plug support, a plurality of anti-slip ribs being symmetrically provided on the outer walls on both sides of the paddle, the outer wall of the cylindrical boss being interference fit with the inner wall of the piston rod, and the cap body and the cylindrical boss being integrally provided.

[0006] Furthermore, the outer wall of the cap body is circumferentially surrounded and integrally provided with a convex ring, and the inner wall of the convex ring is interference-fitted with the outer wall of the wiring harness plug support interface.

[0007] Furthermore, the protective cap is made of rubber.

[0008] The beneficial effects achieved by the utility model are:

[0009] 1. The setting of the cap body covering the interface of the wiring harness plug support effectively prevents dust, dirt and other impurities from entering the interface of the wiring harness plug support, thereby ensuring the cleanliness of the interface and extending the service life of the wiring harness plug. At the same time, the interference fit between the cylindrical boss and the wiring harness plug support interface enhances the connection stability between the protective cap and the support, preventing the protective cap from falling off due to vibration or external force. At the same time, the interference fit setting also effectively prevents water from entering the wiring harness plug support through the wiring harness plug support interface, thereby playing a waterproof role.

[0010] 2. The setting of the paddle makes it easier for users to insert and remove the protective cap, especially when the dust cap needs to be opened or closed frequently.

[0011] 3. The setting of anti-slip ribs increases the resistance between the pick and the clamping tool, playing an anti-slip role.

[0012] 4. The interference fit between the convex ring and the outer wall of the wiring harness plug support interface can effectively fill the gap between the two and prevent external dust, moisture or other contaminants from entering the interface, thereby improving the sealing performance of the entire system. At the same time, the interference fit design makes the connection between the cap body and the wiring harness plug support tighter and more stable, reducing the possibility of loosening or falling off, and ensuring the reliability and stability of the connection structure.

[0013] 5. The rubber material makes the protective cap wear-resistant and reusable. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, the utility model discloses a dustproof protective cap for a wiring harness plug support of an air spring assembly, comprising: a wiring harness plug support 1, a protective cap 2 installed at the interface of the wiring harness plug support 1, the protective cap 2 comprising a cap body 21 covering the interface of the wiring harness plug support 1 and a cylindrical boss 22 plugged into the interface of the wiring harness plug support 1, a paddle 25 is integrally provided at one end of the cap body 21 away from the wiring harness plug support 1, a plurality of anti-slip ribs 26 are symmetrically provided on the outer walls on both sides of the paddle 25, the outer wall of the cylindrical boss 22 is interference fit with the inner wall of the piston rod, and the cap body 21 and the cylindrical boss 22 are integrally provided.

[0019] Based on the above structure, Figure 1-3 As shown, the setting of the cap body 21 covering the interface of the wiring harness plug support 1 effectively prevents dust, dirt and other impurities from entering the interface of the wiring harness plug support 1, thereby ensuring the cleanliness of the interface and extending the service life of the wiring harness plug. At the same time, the interference fit between the cylindrical boss 22 and the interface of the wiring harness plug support 1 enhances the connection stability between the protective cap and the support, preventing the protective cap from falling off due to vibration or external force. At the same time, the interference fit setting also effectively prevents water from entering the wiring harness plug support 1 through the interface of the wiring harness plug support 1, thereby playing a waterproof role. The setting of the paddle 25 enables the user to plug and unplug the protective cap 2 more easily, especially when the dust cap needs to be frequently opened or closed. The setting of the anti-slip rib 26 increases the resistance between the paddle 25 and the clamping tool, playing an anti-slip role.

[0020] Further, such as Figure 1-3 As shown, the outer wall of the cap body 21 is circumferentially surrounded and integrally provided with a convex ring 23, and the inner wall of the convex ring 23 is interference fit with the outer wall of the interface of the wiring harness plug support 1. The interference fit between the convex ring 23 and the outer wall of the interface of the wiring harness plug support 1 can effectively fill the gap between the two and prevent external dust, moisture or other contaminants from entering the interior of the interface, thereby improving the sealing performance of the entire system. At the same time, the interference fit design makes the connection between the cap body 21 and the wiring harness plug support 1 tighter and more stable, reduces the possibility of loosening or falling off, and ensures the reliability and stability of the connection structure.

[0021] Furthermore, the protective cap 2 is made of rubber material, and the rubber material makes the protective cap 2 wear-resistant and recyclable.

[0022] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
