Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and more specifically, to a waterproof sealing connection device for automotive wiring harnesses. Background Technology

[0002] A waterproof sealing connector for automotive wiring harnesses is a protective component specifically designed for automotive electrical systems to ensure the waterproof and sealing performance of wiring harness connections. It typically consists of waterproof gaskets, sealing sleeves, connectors, and other components, effectively preventing moisture, dust, and other contaminants from entering electrical connection points, avoiding short circuits, corrosion, and other malfunctions, thereby improving the reliability and durability of the vehicle's electrical system. This device is widely used in critical areas of automobiles such as engine compartments, doors, and chassis that are susceptible to moisture, and is a vital component for ensuring the safe operation of the vehicle.

[0003] Most existing connection devices are used on horizontal surfaces, but the position of automotive wiring harness connections is generally not fixed. During actual vehicle use, the connection points of the wiring harness will shake due to the operation of the vehicle's internal components. Long-term shaking can easily cause the connection device to fall off, which will lead to the loss of the device's waterproof seal and affect the use of the wiring harness. In view of this, we propose a waterproof sealing connection device for automotive wiring harnesses. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof sealing connection device for automotive wiring harnesses, in order to solve the problem that the position of the connection of automotive wiring harnesses is generally not fixed. During actual use of the vehicle, the connection of the wiring harness will shake due to the operation of the internal components. Long-term shaking can easily cause the waterproof sealing device to fall off, thereby causing the waterproof seal to lose its function and affecting the use of the wiring harness.

[0005] To achieve the above objectives, a waterproof sealing connection device for automotive wiring harnesses is provided, comprising a protective shell. A clamping assembly is installed on the inner side of the protective shell. The clamping assembly includes a pair of symmetrical flexible upper clamping plates and a flexible lower clamping plate on the inner side of the protective shell. A locking bolt is threaded to the top of the upper clamping plate of the protective shell. Adjusting bolts are rotatably connected to the bottom surfaces on both sides of the lower clamping plate. A locking block is fixedly connected to the upper end of the adjusting bolt. A mounting post is fixedly connected to the inner wall of the protective shell outside the adjusting bolt. The mounting post has multiple slots. The adjusting bolt is slidably inserted into the mounting post. Waterproof sealing rings are installed on both inner walls of the protective shell.

[0006] As a further improvement to this technical solution, a dustproof ring is installed on the inner wall of the protective shell on the outer side of the waterproof sealing ring.

[0007] As a further improvement to this technical solution, two springs are installed at the top of the flexible upper clamping plate and the bottom of the flexible lower clamping plate, and all four springs are connected to the inner wall of the protective shell.

[0008] As a further improvement to this technical solution, anti-slip textures are provided on the inner walls of the flexible upper clamping plate and the flexible lower clamping plate.

[0009] As a further improvement to this technical solution, the top of the flexible upper clamp is provided with a reserved hole, and the reserved hole abuts against the bottom end of the locking bolt.

[0010] As a further improvement to this technical solution, the adjusting bolt extends to the outer side of the bottom of the protective shell, and a rotating handle is installed at the bottom of the adjusting bolt. A storage groove adapted to the size of the rotating handle is opened at the bottom of the protective shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this automotive wiring harness waterproof sealing connection device, the flexible upper clamp, flexible lower clamp, and locking bolt in the clamping assembly work together to apply a uniform clamping force to the wiring harness. Combined with the groove cooperation between the adjusting bolt and the mounting post, the preload on both sides of the wiring harness can be adjusted. This design effectively overcomes the problem of device slippage caused by shaking or non-horizontal installation during vehicle operation, significantly enhances the stability of the connection between the device and the wiring harness, reduces the risk of device detachment due to long-term shaking, and ensures the normal use of the wiring harness through effective waterproof sealing protection.

[0024] Please see Figures 1-4As shown, the purpose of this embodiment is to provide a waterproof sealing connection device for automotive wiring harnesses, including a protective shell 1. A clamping assembly 2 is installed on the inner side of the protective shell 1. The clamping assembly 2 includes a pair of symmetrical flexible upper clamping plates 21 and flexible lower clamping plates 24 on the inner side of the protective shell 1. A locking bolt 23 is threadedly connected to the top of the upper flexible clamping plate 21 of the protective shell 1. Adjusting bolts 26 are rotatably connected to the bottom surfaces on both sides of the flexible lower clamping plate 24. A locking block 261 is fixedly connected to the upper end of the adjusting bolt 26. A mounting post 25 is fixedly connected to the inner wall of the protective shell 1 outside the adjusting bolt 26. Multiple slots 251 are opened on the mounting post 25. The adjusting bolt 26 is slidably inserted into the mounting post 25. Waterproof sealing rings 11 are installed on both inner walls of the protective shell 1. The waterproof sealing rings 11 enable the device to achieve waterproof function. The flexible upper clamping plate 21 and flexible lower clamping plate 24 reduce the long-term contact between rigid parts and wiring harnesses, effectively reducing wear on the wiring harnesses.

[0025] Please see Figure 6 As shown, a dustproof ring 12 is installed on the inner wall of the protective shell 1 outside the waterproof sealing ring 11. The dustproof ring 12 achieves dust prevention, making the device multifunctional.

[0026] Please see Figure 3 As shown, two springs 22 are installed on the top of the flexible upper clamping plate 21 and the bottom of the flexible lower clamping plate 24, and all four springs 22 are connected to the inner wall of the protective shell 1. By setting the springs 22, the springs 22 can pull the flexible upper clamping plate 21 and the flexible lower clamping plate 24, ensuring the rationality of the structure.

[0027] Please see Figure 3 and Figure 4 As shown, the inner walls of the flexible upper clamping plate 21 and the flexible lower clamping plate 24 are provided with anti-slip textures. The anti-slip textures can further make the device fit tightly against the wire harness and reduce the loosening of the device.

[0028] Please see Figure 2 and Figure 3 As shown, the top of the flexible upper clamping plate 21 is provided with a reserved hole 27, and the reserved hole 27 abuts against the bottom end of the locking bolt 23. By the reserved hole 27 abutting against the bottom end of the locking bolt 23, the locking bolt 23 corresponds to the reserved hole 27, ensuring that the locking bolt 23 can be squeezed, and ensuring the realization of the subsequent clamping function.

[0029] Please see Figure 4 and Figure 5 As shown, the adjusting bolt 26 extends to the bottom outer side of the protective shell 1. A rotating handle 262 is installed at the bottom end of the adjusting bolt 26. A storage groove 13 adapted to the size of the rotating handle 262 is provided at the bottom of the protective shell 1. By setting the storage groove 13, the rotating handle 262 can be retracted into the storage groove 13, so that the device can maintain stability when used on a horizontal surface.

[0030] The working principle of this solution is as follows: When using the device on a horizontal surface, the user first inserts the wire harness to be connected into both ends of the device. The bottom of the wire harness abuts against the inner wall of the flexible lower clamp 24. The user then manually rotates the locking bolt 23, which moves downward and pushes the flexible upper clamp 21 closer to the wire harness until it is in contact with the top of the wire harness. When the locking bolt 23 is released, it remains stationary, generating a certain squeezing force to clamp the wire harness connection. This ensures that the device and the wire harness are tightly fitted, reducing the occurrence of slippage. When using the device on a non-horizontal surface, such as at vertical or oblique wire harness connections, the user repeats the above method, inserting the wire harness connection and pushing the flexible upper clamp 21 against the wire harness using the locking bolt 23. At this time, the user can push the adjusting bolt 26 left and right. The flexible lower clamp 24 is moved. Since the adjusting bolt 26 is inserted into the mounting post 25, the adjusting bolt 26 slides along the mounting post 25. The bottom surfaces on both sides of the flexible lower clamp 24 are rotatably connected to the adjusting bolt 26. When the user observes the flexible lower clamp 24 squeezing the wire harness, the rotating handle 262 is rotated, and the adjusting bolt 26 is driven to rotate, causing the locking block 261 to rotate. The locking block 261 engages with the corresponding slot 251. Under the pressure of the pre-tightening force on both sides, the flexible lower clamp 24 and the flexible upper clamp 21 completely clamp the wire harness. The device overcomes the gravity on the non-horizontal surface and reduces its own slippage under the condition of the wire harness shaking inside the vehicle. In addition, the protective shell 1 and the waterproof sealing ring 11 continuously seal and waterproof the wire harness connection.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
