Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, and more specifically, to a waterproof automotive wire harness connector. Background Technology

[0002] Automotive wiring harness connectors are a crucial component of automotive electrical systems. They are responsible for connecting the electrical lines between various electronic devices and components within the vehicle, ensuring stable transmission of current and signals. A wiring harness connector typically consists of two parts: a wiring harness connector and a wiring harness plug. Electrical connections are achieved through a plug-in method, making them an indispensable key component in automotive circuitry.

[0003] However, existing automotive wiring harness connectors suffer from significant deficiencies in sealing. After connection, tiny gaps often exist between the wiring harness structure and the connector interface, which easily become channels for moisture infiltration in humid or rainy environments. Once moisture penetrates, it can cause electrical short circuits or malfunctions, affecting the vehicle's normal operation, and may also damage internal electronic equipment, increasing repair costs. Therefore, improving the sealing performance of automotive wiring harness connectors to prevent moisture infiltration has become a pressing issue in the current technological field.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a waterproof automotive wiring harness connector. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof automotive wiring harness connector.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof automotive wiring harness connector, comprising a wiring harness connector and a wiring harness connector, wherein the waterproof automotive wiring harness connector further comprises:

[0007] A gap-filling mechanism is provided on the wire harness connector. Multiple sets of gap-filling plates are arranged in a circumferential array on the gap-filling mechanism. The gap-filling mechanism is used to cause the multiple sets of gap-filling plates to contract inward to fill the gaps in the wire harness structure and the interface of the wire harness connector.

[0008] The filling and reinforcing mechanism and multiple sets of reinforcing pressure plates are provided on the filling and reinforcing mechanism. The filling and reinforcing mechanism is provided on the gap filling mechanism. When the multiple sets of gap filling pressure plates retract inward to the maximum stroke, the filling and reinforcing mechanism is used to realize the filling action of the multiple sets of reinforcing pressure plates on the end gaps of the multiple sets of gap filling pressure plates.

[0009] Preferably, the gap filling mechanism includes a drive ring movably disposed on the outer surface of the wire harness connector, and multiple sets of drive grooves arranged in a circumferential array on the drive ring. A connecting frame is slidably fitted in the drive groove, and the end of the connecting frame is slidably disposed in a limiting groove and fixedly connected to the gap filling plate. The limiting groove is disposed on the outer peripheral surface of the wire harness connector.

[0010] Preferably, the waterproof automotive wiring harness connector further includes a threaded nut block on the outer periphery of the wiring harness connector and an end face formed on the outer surface of the wiring harness connector. The nut block is connected to the drive ring through a connecting post. By rotating the nut block, the drive ring rotates to achieve the inward contraction of multiple gap filling plates. When the multiple gap filling plates contract inward to their maximum stroke, the nut block abuts against the end face of the wiring harness connector.

[0011] Preferably, the side of the wire mother block near the end face is made of an elastic material.

[0012] Preferably, the filling and reinforcing mechanism includes multiple sets of drive grooves II formed on the drive ring, with connecting brackets II slidably arranged in the multiple drive grooves II, and the ends of the multiple connecting brackets II slidably arranged in limiting grooves II, the limiting grooves II being fixed to the outer surface of the wire harness connector.

[0013] Preferably, in a clockwise direction, the angle between the first drive slot and the outer surface of the wire harness connector is smaller than the angle between the second drive slot and the outer surface of the wire harness connector.

[0014] Preferably, both the gap filling plate and the reinforcing plate are made of rubber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Enhanced sealing: The multiple sets of gap-filling plates of the gap-filling mechanism retract inward to effectively fill the gaps at the interface between the wire harness structure and the wire harness connector, initially enhancing the sealing performance and preventing moisture infiltration. Furthermore, when the wire harness filling plate is filled to its maximum stroke, the filling reinforcement mechanism further fills the gap at the end of the gap-filling plate with multiple sets of reinforcing plates, significantly improving the sealing effect and achieving excellent waterproof characteristics.

[0017] 2. Enhanced fastening effect: The pressing contact between the gap filling plate and the wire harness connector not only enhances the sealing performance, but also improves the fastening effect after the wire harness connector and wire harness structure are connected, ensuring the stability of the connection.

[0018] 3. Easy to operate: The drive ring can be rotated by rotating the screw block, which in turn drives the gap filling plate and the reinforcing plate. The operation is simple and quick, improving work efficiency. Attached Figure Description

Detailed Implementation

[0025] like Figure 1-4 As shown, this utility model provides a waterproof automotive wiring harness connector, including a wiring harness connector 1 and a wiring harness connector 6. The wiring harness connector 1 is connected by inserting it into the wiring harness connector 6. In order to improve the sealing performance of the mating gap between the wiring harness connector 6 and the wiring harness connector 1 after connection, the waterproof automotive wiring harness connector also includes a gap filling mechanism disposed on the wiring harness connector 6. Multiple sets of gap filling plates 4 are arranged in a circumferential array on the gap filling mechanism. The gap filling mechanism is used to cause the multiple sets of gap filling plates 4 to shrink inward to fill the gap at the interface between the wiring harness structure and the wiring harness connector 6. The gap filling mechanism causes the multiple gap filling plates 4 to shrink inward and fit against the outer surface of the connection gap between the wiring harness connector 6 and the wiring harness connector 1, thereby initially filling the gap and thus initially increasing the overall sealing performance after the wiring harness connector 6 and the wiring harness structure are mated.

[0026] Furthermore, when the wire harness structure and the wire harness connector 6 are connected, the plug protrusion 2 provided on the wire harness connector 1 will also be plugged into the plug groove 10, which can also improve the sealing effect to a certain extent.

[0027] To further improve the sealing effect, a filling reinforcement mechanism is also provided on the gap filling mechanism. This filling reinforcement mechanism is further equipped with multiple sets of reinforcing pressure plates 3. When the multiple sets of gap filling plates 4 retract inward to their maximum stroke, the filling reinforcement mechanism is used to achieve the filling action of the multiple sets of reinforcing pressure plates 3 on the end gaps of the multiple sets of gap filling plates 4. When the multiple gap filling plates 4 retract inward to their maximum stroke, that is, when they are in contact with the outer surface of the gap at the interface between the wire harness connector 6 and the wire harness joint 1, the multiple gap filling plates 4, due to their separate design, even with multiple... Even when the ends of the gap filling plates 4 abut against each other, gaps will still inevitably remain. At this time, the filling and reinforcing mechanism causes the multiple reinforcing plates 3 to contract inward and abut against the outer periphery of the gap where the ends of the multiple gap filling plates 4 abut against each other, thereby filling the gap, further improving the sealing effect and achieving waterproof characteristics. Furthermore, after the wire harness connector 1 and the wire harness connector 6 are connected to each other, the pressing contact between the gap filling plates 4 and the wire harness connector 6 can also enhance the fastening effect after the wire harness connector 6 and the wire harness structure are connected, which has multiple practical effects.

[0028] In one embodiment of this utility model, the gap filling mechanism includes a drive ring 5 movably disposed on the outer surface of the wire harness connector 6, and multiple sets of drive grooves 13 arranged in a circumferential array on the drive ring 5. A connecting frame 14 is slidably fitted in the drive groove 13, and the end of the connecting frame 14 is slidably disposed in the limiting groove 9 and fixedly connected to the gap filling plate 4. The limiting groove 9 is disposed on the outer peripheral side surface of the wire harness connector 6. By rotating the drive ring 5, the multiple drive grooves 13 are rotated. At this time, under the action of the limiting groove 9, the multiple connecting frames drive the multiple gap filling plates 4 to slide along the limiting groove 9, thereby shrinking inward until the multiple gap filling plates 4 press against the outer surface of the interface gap position of the wire harness connector 1 and the wire harness connector 6, thereby filling the gap and initially enhancing the sealing effect.

[0029] To enable the drive ring 5 to rotate, the waterproof automotive wiring harness connector 6 also includes a threaded nut 7 threaded onto the outer periphery of the connector 6 and an end face formed on the outer surface of the connector 6. The nut 7 is connected to the drive ring 5 via a connecting post 8. Rotating the nut 7 causes the drive ring 5 to rotate, thereby causing multiple gap filling plates 4 to retract inward. When the multiple gap filling plates 4 retract to their maximum stroke, the nut 7 abuts against the end face of the connector 6. Rotating the nut 7 causes it to rotate and move on the connector 6, thereby enabling the drive ring 5 to rotate. During the rotation and movement, multiple gap filling plates 4 retract inward. After the thread nut 7 moves to its maximum stroke, the multiple gap filling plates 4 retract inward to their maximum stroke and fill the gap. At this time, the thread nut 7 abuts against the end face. In order to fix the position of the thread nut 7 and prevent the reaction force of the multiple gap filling plates 4 after pressing the gap from causing the thread nut 7 to rotate in the opposite direction and affecting the sealing effect, a nut can also be threaded on the outer surface of the wire harness connector 6. By rotating the nut, the thread nut 7 is pressed against the end face, thereby fixing the thread nut 7 and preventing loosening.

[0030] Furthermore, the side of the nut block 7 near the end face is made of elastic material, which can further enhance the fixing effect on the nut block 7 and further prevent loosening;

[0031] In another embodiment of this utility model, the filling and reinforcing mechanism includes multiple sets of driving grooves 12 formed on the driving ring 5. Connecting brackets 11 are slidably disposed within the multiple driving grooves 12, and the ends of the multiple connecting brackets 11 are slidably disposed within limiting grooves 15. The limiting grooves 15 are fixed to the outer surface of the wire harness connector 6. When the driving ring 5 rotates, in addition to the gap filling plate 4 retracting inward, the multiple reinforcing plates 3 also retract inward. Since the initial position of the gap filling plate 4 is closer to the wire harness connector 6, the gap filling plate 4 will fill the gap first. Furthermore, due to the distance between the driving groove 13 and the outer surface of the wire harness connector 6... The angle is smaller than the angle between the drive groove 12 and the outer surface of the wire harness connector 6. In this way, when the drive ring 5 rotates by the same angle, the reinforcing pressure plate 3 will contract a greater distance. Thus, after the gap filling plate 4 presses the gap, the reinforcing pressure plate 3 immediately fills the gap at the ends of multiple gap filling plates 4. Due to the different angles, and since both the gap filling plate 4 and the reinforcing pressure plate 3 are made of rubber, the contact between the reinforcing pressure plate 3 and the gap filling plate 4 causes both the gap filling plate 4 and the reinforcing pressure plate 3 to deform, thereby further improving the sealing and waterproof performance, as well as the tightness after installation. It has good practicality and is suitable for widespread application.

However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are within the protection scope of this utility model's technical solution.
