Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harnesses, specifically to a waterproof and dustproof rubber plug for protecting connectors. Background Technology

[0002] A sealant in automotive wiring harnesses is a component used to seal the ends of the harness or the cavity of the connector. Its main function is to prevent the intrusion of foreign objects such as moisture and dust, while also reducing electromagnetic interference. However, existing sealants are prone to falling off due to temperature changes or vibrations, affecting the sealing performance of the wiring harness.

[0003] Welcome light connectors are typically located on the door sill or under the door, directly exposed to the elements and susceptible to corrosion from moisture, dust, and other environmental factors, leading to oxidation or short circuits. Traditional protection methods usually involve installing a matching female connector, but this is costly. To address the issue of waterproofing and dustproofing the welcome light connectors when not in use, while also ensuring easy installation and removal and reusability, this waterproof and dustproof rubber plug was designed. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a waterproof and dustproof rubber plug for protecting connectors, so as to solve at least one of the above-mentioned technical problems.

[0005] The technical solution of this utility model is: a waterproof and dustproof rubber plug for protecting connectors, comprising a plug body, characterized in that the plug body comprises an integrally formed rubber part, the rubber part comprising an upper end and a lower end, the upper end being an upward-opening groove, the outer contour of the groove fitting the connector, the groove comprising a hollow square tube with a rounded rectangular outer contour and a bottom plate, the bottom plate being integrally formed with the hollow square tube, and the outer side of the bottom plate being connected to the lower end;

[0006] The lower end is a pull rod, which is a cylindrical structure. The outer diameter of the pull rod is smaller than the width of the base plate. A reinforcing rib is provided on the inner side of the base plate. The reinforcing rib is a block-shaped protrusion, and the mounting position of the reinforcing rib is opposite to the mounting position of the pull rod.

[0007] The outer wall of the hollow square tube is provided with a limiting groove.

[0008] This utility model employs a contour-following design to match the shape of the connector, and is integrally injection molded with rubber, balancing sealing and reliability. It features a simple and practical structure, low cost, and easy mass production. No auxiliary tools are required for installation or disassembly, and the mold can be adjusted to adapt to different vehicle models. Internal reinforcing ribs increase the rubber's sealing strength.

[0009] In a further preferred embodiment, the limiting groove is disposed on both sides of the hollow square tube, and the limiting groove is opened from top to bottom along the height direction of the groove body, and the height of the limiting groove is less than the height of the groove body.

[0010] The limiting groove allows for easy insertion even when there is obstruction.

[0011] Further preferably, the height of the reinforcing rib is less than half the height of the groove.

[0012] This invention reduces the overall weight while maintaining strength by limiting the height of the reinforcing ribs.

[0013] Further preferred, the wall thickness of the hollow square tube gradually increases from top to bottom.

[0014] This increases flexibility and facilitates connection with connectors.

[0015] Further preferably, the length of the pull rod is greater than the height of the groove.

[0016] It allows for easy insertion of the plug deeper for convenient removal. Attached Figure Description

[0017] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0018] Figure 2 This is a cross-sectional view of the present invention.

[0019] In the diagram: 1 is a hollow square tube; 2 is a tie rod; 3 is a limiting groove; 4 is a reinforcing rib; 5 is a base plate. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Reference Figures 1-2 As shown, a waterproof and dustproof rubber plug for protecting connectors includes a plug body, which includes an integrally molded rubber component. The rubber component includes an upper end and a lower end. The upper end is an upward-opening groove whose outer contour fits the connector. The groove includes a hollow square tube 1 with a rounded rectangular outer contour and a base plate 5. The base plate and the hollow square tube are integrally structured, and the lower end is connected to the outer side of the base plate. The lower end is a pull rod 2, which is a cylindrical structure. The outer diameter of the pull rod is smaller than the width of the base plate. A reinforcing rib 4 is provided on the inner side of the base plate. The reinforcing rib is a block-shaped protrusion, and its mounting position is opposite to the mounting position of the pull rod. A limiting groove 3 is provided on the outer wall of the hollow square tube.

[0022] This utility model employs a contour-following design to match the shape of the connector, and is integrally injection molded with rubber, balancing sealing and reliability. It features a simple and practical structure, low cost, and easy mass production. No auxiliary tools are required for installation or disassembly, and the mold can be adjusted to adapt to different vehicle models. Internal reinforcing ribs increase the rubber's sealing strength.

[0023] Further optimization involves setting limiting grooves on both sides of the hollow square tube, with the grooves extending from top to bottom along the height of the tube body, and the height of the limiting grooves being less than the height of the tube body. The limiting grooves facilitate easy insertion of the plug.

[0024] Further preferably, the height of the reinforcing rib is less than half the height of the tank body. This invention reduces the overall weight while maintaining strength by limiting the height of the reinforcing rib.

[0025] Further optimization involves gradually increasing the wall thickness of the hollow square tube from top to bottom. This increases its flexibility and facilitates easy connection with connectors.

[0026] Further optimization involves ensuring the pull rod is longer than the groove's height. This allows for easier insertion of the plug deeper for convenient retrieval.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
