Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a shock-absorbing vehicle communication connector. Background Technology

[0002] The vehicle communication connector is a key component in automotive electronic systems for signal transmission and power connection. Its performance directly affects the reliability of vehicle intelligence and connectivity functions. Its specific structure includes a connector plug for electrical connection, a connector part with electrical components inside one end of the connector plug for connecting power lines, and a power line connected to the connector plug through the connector part. Electrical connection and signal transmission can be completed by plugging the connector plug into the communication interface on the vehicle.

[0003] However, in the prior art, because cars are prone to vibration during driving, the energy of the vibration is transmitted to the connector through the car body, causing the connector to shake. Under long-term vibration, the connector is very likely to become loose or the contact resistance will increase, resulting in signal interruption or overheating. To address this, this application proposes a vibration-damping vehicle communication connector to reduce the impact of vibration energy on the connector. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a shock-absorbing vehicle communication connector for reducing the impact of vibration energy on the connector.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a shock-absorbing vehicle communication connector, including a connector plug, a power cord, a connecting part for connecting the power cord, and a shock-absorbing device for reducing the impact of vibration energy on the connector plug. The power cord is installed on the connecting part. The shock-absorbing device includes a fixed housing and a plurality of elastic components disposed inside the fixed housing for squeezing the connector plug. The fixed housing is hollow inside and has through holes at both ends that penetrate the fixed housing. The plurality of elastic components are arranged around the connector plug.

[0006] Furthermore, the elastic component includes a compression plate mounted on the inner wall of the fixed housing and a compression spring fixedly connected to the inner wall of the fixed housing for pushing the compression plate to compress the connector plug. One end of the compression spring is fixedly connected to the inner wall of the fixed housing, and the other end is fixedly connected to the compression plate. The compression plate is mounted on the inner wall of the fixed housing through the compression spring.

[0007] By adopting the above technical solution, the communication interface is first covered by a fixed housing, and then the fixed housing is fixed to the vehicle body. When the staff plugs the communication interface on the car with the connector, during this process, the end of the connector pushes the compression plate to move towards the compression spring, so that the compression plate compresses the compression spring, and the compressed compression spring pushes the compression plate to squeeze the outside of the connector.

[0008] When the energy of vibration is transmitted to the connector through the vehicle body, multiple elastic components apply a uniform elastic compression to the outside of the connector. These elastic components securely wrap around and fix the connector, ensuring its stability in the assembled state and significantly improving its impact resistance. Specifically, the compression plate absorbs and disperses vibration energy through the compression spring, effectively buffering the direct impact of external forces on the connector and achieving reliable shock absorption protection. This effectively reduces the impact of vibration energy on the connector, achieving the goal of reducing the impact of vibration energy on the connector and improving the overall stability of the connector.

[0009] Furthermore, mounting plates are fixed on both sides of one end of the fixed housing to facilitate fixing the fixed housing to the vehicle body.

[0010] By adopting the above technical solution, the mounting plate enables workers to fix the housing to the vehicle body. For example, threaded holes can be made on the mounting plate and the vehicle body to fix the housing with bolts, or the mounting plate can be welded to the vehicle body to fix the housing to the vehicle body.

[0011] Furthermore, the interior of the fixed housing at the end away from the mounting plate is provided with a limiting component to prevent the connector from detaching from the fixed housing.

[0012] Furthermore, the limiting assembly includes two parallel limiting plates and two control rods that are inserted into the fixed housing from both sides and fixedly connected to the limiting plates, with the control rods inserted into the fixed housing.

[0013] While the shock absorption device improves the overall stability of the connector by adopting the above technical solution, the connector will still be affected by significant vibration energy when the vehicle encounters large bumps during operation. This could cause the connector plug to move away from the communication interface due to the vibration energy, gradually detaching from the fixed housing. The limiting component solves this technical problem. After the operator plugs the connector plug into the communication interface on the vehicle, they can push two control rods towards the center of the fixed housing. This causes two limiting plates to be located on both sides of the connection part, blocking the end of the connector plug away from the communication interface and preventing it from moving away from the communication interface. This prevents the connector plug from gradually detaching from the fixed housing and improves the stability of the connector when subjected to large vibration energy.

[0014] Furthermore, the ends of the two control rods furthest from the limiting plate are provided with fixing components for fixing the limiting plate.

[0015] Furthermore, the fixing assembly includes two connecting rods respectively fixedly mounted on the ends of the two control rods away from the limiting plate and extending upward to the top of the fixing housing, two fixing rods respectively fixedly mounted on the top ends of the two connecting rods and extending laterally to the middle of the fixing housing, two fixing blocks respectively fixedly mounted on the ends of the two fixing rods away from the connecting rods and extending upward, and fixing bolts passing through the two fixing blocks and threadedly connected to the fixing blocks.

[0016] While the above technical solution improves the stability of the connector under significant vibration, the random movement of the plug during vibration means it doesn't always move away from the communication interface. This means the limit plates cannot withstand the pressure of the plug moving away from the interface at all times, potentially causing them to shift towards the sides of the housing due to vibration. Consequently, the limit plates may fail to block the plug. The fixing component solves this problem by using fixing bolts to secure the limit plates via fixing blocks, fixing rods, and connecting rods, preventing the limit plates from shifting due to vibration. The movement of the limiting components to both sides of the fixed housing due to vibration enhances the stability of the limiting components. Furthermore, the fixing bolts allow operators to easily remove the connector by simply turning them counterclockwise. The fixing blocks, via the fixing rod, connecting rod, and control rod, move the two limiting plates away from each other, making connector disassembly more convenient. Because the fixing blocks are located at the end of the fixing rod furthest from the connecting rod, when the operator turns the fixing bolts clockwise to bring the two limiting plates closer together, the two fixing blocks gradually move to the center of the fixing bolt, providing support and extending its service life under vibration.

[0017] Furthermore, the sides of the limiting plate and the extrusion plate that are close to each other are coplanar.

[0018] By adopting the above technical solution, the limiting plate and the extrusion plate form a box structure, preventing the connection plug from having room to move backward after being wrapped by the elastic component.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting up a shock absorption device, the communication interface is first covered by a fixed housing, which is then fixed to the vehicle body. When the operator plugs the connector into the communication interface on the vehicle, the end of the connector pushes the compression plate towards the compression spring, causing the compression plate to compress the compression spring. The compressed compression spring then pushes the compression plate to press against the outside of the connector. When the vibration energy is transmitted to the connector through the vehicle body, multiple elastic components apply elastic compression evenly to the outside of the connector. These multiple elastic components can securely wrap and fix the connector, which not only ensures the stability of the connector in the assembled state but also significantly improves its impact resistance, achieving the goal of reducing the impact of vibration energy on the connector and improving the overall stability of the connector.

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Example, refer to Figure 1 , Figure 2A shock-absorbing vehicle communication connector includes a connector plug 1, a power cord 10, a connecting portion 11 for connecting the power cord 10, and a shock-absorbing device 2 for reducing the impact of vibration energy on the connector plug 1. The power cord 10 is mounted on the connecting portion 11. The shock-absorbing device 2 includes a fixed housing 20 and a plurality of elastic components 21 disposed inside the fixed housing 20 for pressing the connector plug 1. The fixed housing 20 is hollow inside and has through openings at both ends. Mounting pieces 200 are fixed on both sides of one end of the fixed housing 20 to facilitate fixing the fixed housing 20 to the vehicle body. The plurality of elastic components 21 are arranged around the connector plug 1. Each elastic component 21 includes a pressing plate 210 mounted on the inner wall of the fixed housing 20 and a pressing plate 210 fixedly connected to the inner wall of the fixed housing 20 for pushing the pressing plate 210 to press the connector plug 1. A compression spring 211 is fixedly connected at one end to the inner wall of the fixed housing 20 and at the other end to the compression plate 210. The compression plate 210 is installed on the inner wall of the fixed housing 20 through the compression spring 211. First, the fixed housing 20 covers the communication interface. Then, the mounting plate 200 is used to fix the fixed housing 20 with bolts by making threaded holes in the mounting plate 200 and the vehicle body, or the mounting plate 200 is welded to the vehicle body to fix the fixed housing 20 to the vehicle body. When the operator plugs the communication interface on the car with the connector 1, during this process, the end of the connector 1 pushes the compression plate 210 to move towards the compression spring 211, so that the compression plate 210 compresses the compression spring 211. The compressed compression spring 211 pushes the compression plate 210 to compress the outside of the connector 1.

[0026] When the energy of vibration is transmitted to the connector 1 through the vehicle body, multiple elastic components 21 apply elastic compression to the outside of the connector 1 evenly. The multiple elastic components 21 can firmly wrap and fix the connector 1, which not only ensures the stability of the connector in the assembled state, but also significantly improves its impact resistance. The specific process is as follows: the compression plate 210 absorbs and disperses the vibration energy through the compression spring 211, thereby effectively buffering the direct impact of external forces on the connector and realizing a reliable shock absorption protection function. This can effectively reduce the impact of vibration energy on the connector, achieve the purpose of reducing the impact of vibration energy on the connector, and improve the overall stability of the connector.

[0027] Although the shock absorption device 2 improves the overall stability of the connector, when the vehicle encounters large bumps during driving, the connector will be affected by significant vibration energy. This may cause the connector plug 1 to move away from the communication interface due to the vibration energy, causing the connector plug 1 to gradually detach from the fixed housing 20. To solve this technical problem, this embodiment provides a limiting component 3 inside the fixed housing 20 at the end away from the mounting piece 200 to prevent the connector plug 1 from detaching from the fixed housing 20. The limiting component 3 includes two parallel limiting plates 30 and two guide rods respectively extending from the fixed housing. The control rods 31, which are fixedly connected to the limiting plate 30, are inserted into the fixed housing 20. The control rods 31 are inserted into the fixed housing 20. With the setting of the limiting component 3, after the operator plugs the connector 1 into the communication interface on the car, by pushing the two control rods 31 towards the middle of the fixed housing 20, the two limiting plates 30 are located on both sides of the connecting part 11 and block the end of the connector 1 away from the communication interface, thus restricting the connector 1 from moving away from the communication interface. This prevents the connector 1 from gradually detaching from the fixed housing 20 and improves the stability of the connector when subjected to large vibration energy.

[0028] Although the limiting component 3 improves the stability of the connector when subjected to large vibration energy, the movement of the connector plug 1 during vibration is disordered. This means that the connector plug 1 will not move away from the communication interface at all times. Consequently, the limiting plate 30 cannot withstand the pressure of the connector plug 1 moving away from the communication interface at all times. This may cause the limiting plate 30 to move to both sides of the fixed housing 20 due to the vibration, resulting in the two limiting plates 30 failing to block the connector plug 1. To solve this technical problem, this embodiment provides a fixing component 4 for fixing the limiting plate 30 at the ends of the two control rods 31 away from the limiting plate 30. The fixing component 4 includes two connecting rods 40 respectively fixedly mounted on the ends of the two control rods 31 away from the limiting plate 30 and extending upward to the top of the fixed housing 20, two fixing rods 41 respectively fixedly mounted on the top of the two connecting rods 40 and extending laterally to the middle of the fixed housing 20, and two fixing blocks 42 respectively fixedly mounted on the ends of the two fixing rods 41 away from the connecting rods 40 and extending upward. The fixing bolts 43, which pass through the two fixing blocks 42 and are threaded onto the fixing blocks 42, are provided by the fixing assembly 4. Through the fixing blocks 42, the fixing bolts 43 fix the limiting plate 30 via the fixing blocks 42, the fixing rod 41, and the connecting rod 40, preventing the limiting plate 30 from moving to either side of the fixing housing 20 due to vibration. This improves the stability of the limiting assembly 3. Furthermore, by using the fixing bolts 43, when the operator needs to unplug the connector 1, they only need to turn the fixing bolts 43 counterclockwise to reposition the two fixing blocks 42. The fixing block 42, through the fixing rod 41, connecting rod 40, and control rod 31, moves the two limiting plates 30 away from each other, making it easier for workers to disassemble the connector. Because the fixing block 42 is located at the end of the fixing rod 41 away from the connecting rod 40, when the worker turns the fixing bolt 43 clockwise to bring the two limiting plates 30 closer together, the two fixing blocks 42 will gradually move to the middle of the fixing bolt 43, providing support for the middle of the fixing bolt 43 and extending the service life of the fixing bolt 43 in a vibration environment.

[0029] In this embodiment, the sides of the limiting plate 30 and the pressing plate 210 that are close to each other are coplanar, so that the limiting plate 30 and the pressing plate 210 form a box structure, preventing the connection plug 1 from having room to move backward after being fixed by the pressing plate 210.

[0030] The specific implementation process is as follows: First, the communication interface is covered by the fixed housing 20. Then, the fixed housing 20 is fixed by bolts through threaded holes in the mounting plate 200 and the vehicle body, or the mounting plate 200 is welded to the vehicle body to fix the fixed housing 20 to the vehicle body. Then, the connector 1 is plugged into the communication interface on the car. During this process, the end of the connector 1 pushes the compression plate 210 to move towards the compression spring 211, so that the compression plate 210 compresses the compression spring 211. The compressed compression spring 211 pushes the compression plate 210 to press the outside of the connector 1. Then, the fixing bolt 43 is turned clockwise to bring the two fixing blocks 42 closer to each other. The fixing blocks 42 drive the two limiting plates 30 to move closer to each other through the fixing rod 41, the connecting rod 40 and the control rod 31. The two limiting plates 30 are combined together to block the end of the connector 1 away from the communication interface, restricting the connector 1 from moving away from the communication interface, thus preventing the connector 1 from gradually detaching from the fixed housing 20 and completing the installation of the connector.

[0031] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
