[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] This embodiment describes a fixing device for a PCE electrical connector and a rail engineering vehicle, which relates to the field of rail operation platform vehicle technology. A socket in a power-off state is provided on the vehicle body 300, and reinforcement components 200 are provided on both sides of the socket to reinforce the PCE electrical connector inserted into the socket. During the movement of the rail engineering, the PCE electrical connector is prevented from falling out of the socket, thus protecting the PCE electrical connector.

[0033] Please see Figures 1 to 7 A fixing device for a PCE electrical connector in this embodiment includes a fixing socket 100 and at least one reinforcing component 200. The PCE electrical connector can be inserted into the fixing socket 100 to protect the PCE electrical connector, and the reinforcing component 200 can prevent the PCE electrical connector from coming out of the fixing socket 100.

[0034] The fixed socket 100 includes a mating cavity 110 that mates with a PCE electrical connector, allowing the PCE electrical connector to be fully inserted into the mating cavity 110. The mating cavity 110 provides a precise mating position between the connector and the fixed socket 100, ensuring that the connector does not deviate from the correct position during insertion, preventing external debris from entering the interior of the PCE electrical connector, and providing structural protection for the PCE electrical connector.

[0035] The reinforcement component 200 includes a base 210, a lever arm 220, and a pressure plate 230. The base 210 is fixedly connected to the fixed socket 100. The middle part of the lever arm 220 is rotatably connected to the base 210, and one end of the lever arm 220 relative to the PCE electrical connector is fixedly connected to the pressure plate 230. The base 210 and the fixed socket 100 provide stable support for the entire motion system. The rotatable connection between the lever arm 220 and the base 210, and the fixed connection of one end of the lever arm 220 to the pressure plate 230, allows the other end to drive the pressure plate 230 through leverage, applying pressure to the PCE electrical connector and providing a flexible locking and releasing mechanism. The pressure plate 230 is positioned perpendicular to the lever arm 220, allowing it to apply pressure evenly to the edge of the PCE electrical connector, ensuring a tight lock and preventing loosening of the PCE electrical connector in the connected state.

[0036] The lever arm 220 is relatively telescopic, allowing the reinforcing gripper 200 to adapt to the vibration and external impact of the rail engineering vehicle. The lever arm 220 can adjust the pressure according to different force directions and amplitudes, ensuring that the joint is always stably held in the socket and is not easily loosened due to vibration or collision.

[0037] During use, the reinforcing component 200 has a clamped state and a relaxed state relative to the PCE electrical connector. In the relaxed state, the lever arm 220 is relatively relaxed and tilted downwards, while the insertion cavity 110 of the fixed socket 100 is relatively open. After the PCE electrical connector is inserted into the insertion cavity 110, the lever arm 220 first rotates relative to the PCE electrical connector, causing the pressure plate 230 to abut against the edge of the PCE electrical connector. The lever arm 220 is then stretched, causing the pressure plate to elastically press the PCE electrical connector.

[0038] It should be noted that the fixed socket 100 is equipped with a sealing cover 120, which is hinged to the fixed socket 100. During the operation of the PCE electrical connector, the fixed socket 100 is relatively open, and the sealing cover 120 can seal the insertion cavity 110 of the fixed socket 100 to prevent outdoor debris from entering. The hinged part of the sealing cover 120 and the fixed socket 100 is spaced apart from the reinforcing component 200, and the sealing cover 120 and the reinforcing component 200 can move relatively independently to avoid interference between them.

[0039] In some embodiments, please refer to Figures 1 to 5The lever arm 220 includes a rotating arm body 221 and a latching arm body 222. One end of the rotating arm body 221 is rotatably connected to the seat body 210, and both ends of the latching arm body 222 are connected to the pressure plate 230 and the other end of the rotating arm body 221, respectively. The multi-bar connection structure formed by the rotating arm body 221 and the latching arm body 222 provides a more efficient clamping mechanical mechanism. The rotating arm body 221 can be flexibly adjusted in the direction of force. Through rotation and cooperation with the latching arm body 222, it is ensured that the pressure plate 230 can apply pressure evenly and continuously to the PCE electrical connector.

[0040] During the operation of the rail engineering vehicle, the vehicle body 300 will be subjected to vibration and impact. The multi-bar connection structure can adapt to and mitigate the transmission of these forces through the rotation structure, and prevent the joints from loosening during operation.

[0041] In some embodiments, please refer to Figures 3 to 5 The latch arm 222 includes two oppositely arranged latching members 222a and an elastic member 222b. The relatively close ends of the two latching members 222a are connected by the elastic member 222b. The elastic member 222b can drive the two latching members 222a to move towards each other. The relatively far ends of the two latching members 222a are respectively connected to the pressure plate 230 and the rotating arm 221.

[0042] The movement of the snap-fit ​​element 222a is controlled by the elastic element 222b, allowing the elastic element 222b to automatically adjust the pressure according to the edge characteristics of the connector after insertion. Simultaneously, by replacing the elastic element 222b with one of different elastic coefficients, the elastic element 222b can provide a certain pressure to the snap-fit ​​element 222a, ensuring that the connector is securely fixed during connection without being damaged due to over-tightening. This self-adjusting function improves the clamping accuracy and avoids excessive compression.

[0043] The elastic element 222b can absorb and buffer external vibrations and impacts to a certain extent. Especially in rail engineering vehicles, vibration and impact are common working conditions. The presence of the elastic element 222b effectively mitigates the impact of these external forces on the joint fixing effect, allowing the joint to remain stable in unstable environments.

[0044] In practical implementation, the two snap-fit ​​connectors 222a are staggered relative to each other, and the elastic elements 222b are respectively fitted onto the overlapping areas of the two snap-fit ​​connectors 222a. The relatively close ends of the two snap-fit ​​connectors 222a act on the elastic elements 222b respectively. The staggered arrangement of the snap-fit ​​connectors 222a allows them to work in better coordination. When the elastic element 222b pushes the snap-fit ​​connector 222a with its elastic force, the staggered structure ensures that the two snap-fit ​​connectors 222a move simultaneously and evenly towards the joint, thereby applying pressure evenly.

[0045] The staggered arrangement of the snap-fit ​​connectors 222a can improve the clamping efficiency of the connector, avoid the risk of uneven pressure applied to the connector by the two snap-fit ​​connectors 222a, and ensure that the connector can be clamped more stably when inserted.

[0046] The staggered arrangement of the elastic element 222b and the snap-fit ​​element 222a makes the structure of the entire fixing device more compact and optimizes the internal space. This allows the device to achieve efficient clamping function in a small space, making it very suitable for equipment such as rail engineering vehicles with limited space.

[0047] It should be noted that the elastic element 222b is a compression spring. The two snap-fit ​​parts 222a have protrusions at their opposite ends that snap-fit ​​the compression spring. The far ends of the two snap-fit ​​parts 222a are far apart from each other, and the protrusions are close to each other, so as to compress the compression spring. The compression spring applies a force to the snap-fit ​​parts 222a to press the PCE electrical connector.

[0048] In some embodiments, the pressure plate 230 is provided with friction texture, which can enhance the friction between the pressure plate 230 and the edge of the PCE electrical connector, and prevent the pressure plate 230 from slipping off the PCE electrical connector when the force is uneven.

[0049] In some embodiments, please refer to Figure 3 The base 210 includes a connecting base 211 and an assembly base 212. The connecting base 211 and the assembly base 212 are fixedly connected, and the lever arm 220 is rotatably connected to the connecting base 211. The assembly base 212 is fitted against and detachably connected to the outer wall of the fixed socket 100. This detachable connection between the assembly base 212 and the outer wall of the fixed socket 100 makes the installation and disassembly of the entire fixing device more convenient. When maintenance, inspection, or replacement of certain parts is required, operators can easily separate the assembly base 212 from the fixed socket 100 without a complicated disassembly process, improving maintenance efficiency and reducing repair difficulty.

[0050] The fixed connection between the connecting seat 211 and the mounting seat 212 ensures the stability of the entire seat 210 and prevents loosening between the mounting seat 212 and the fixed socket 100. The fixed connection structure ensures that the lever arm 220 can rotate stably during use and maintains precise contact with the socket during the clamping process.

[0051] Meanwhile, the precise fit between the mounting base 212 and the fixed socket 100 ensures accurate engagement between the lever arm 220 and the connector during operation, thereby improving the locking effect. This stable connection allows the entire fixing device to operate efficiently and stably.

[0052] As a further embodiment, the mounting base 212 has an arc-shaped portion 121a relative to the fixed socket 100. The arc-shaped portion 121a is consistent with the outer contour of the fixed socket 100, allowing the mounting base 212 and the fixed socket 100 to fit perfectly together. The precise fit between the mounting base 212 and the fixed socket 100 ensures a large contact area between the mounting base 212 and the socket, thereby improving the stability and firmness of the connection. The arc-shaped portion 121a effectively reduces the gap at the connection point, avoiding problems such as loosening or uneven force distribution, and can better transmit force, preventing unstable clamping caused by asymmetrical connection.

[0053] The curved portion 121a is connected to the fixed socket 100 by bolts. The bolt connection provides strong mechanical fixing force, making the connection between the mounting base 212 and the socket very stable. The bolt connection can withstand large forces, ensuring that the device can still work stably under high load or high vibration environments and will not loosen due to external forces.

[0054] Please see Figure 7 This application provides a rail engineering vehicle, including a fixing device for multiple PCE electrical connectors and a vehicle body 300. Each fixing socket 100 has a plug-in cavity 110 adapted to different models of PCE electrical connectors. The fixing socket 100 is connected to the vehicle body 300. The connection between the fixing socket 100 and the vehicle body 300 allows the PCE electrical connectors to be securely fixed to the vehicle body 300, preventing the electrical connectors from loosening or being damaged due to external vibration or collision during transportation and operation.

[0055] Each fixed socket 100 is designed with a plug-in cavity 110 that is compatible with different models of PCE electrical connectors, which can meet the different needs of different types of rail engineering vehicles for electrical connectors. The fixed socket 100 can be compatible with 24V, 220V, 400V and other models of PCE electrical connectors, making the connection of the electrical system and power supply of the rail engineering vehicle more flexible.

[0056] In some embodiments, please refer to 7, the vehicle body 300 is provided with a railing 310 and a PCE electrical connector. A fixed socket 100 is connected to the railing 310, and the PCE electrical connector is inserted into the fixed socket 100. A reinforcing component 200 is snapped onto the PCE electrical connector. The snapping of the reinforcing component 200 onto the PCE electrical connector effectively increases the stability and fixation of the connector. The reinforcing component 200 not only ensures a secure connection between the connector and the fixed socket 100, but also reduces the risk of the connector loosening or falling off in high-vibration environments, improving the connector's impact and vibration resistance.

[0057] The combination of the reinforcement component 200 and the joint makes the joint less susceptible to external environmental factors (such as vibration, impact, external force) and accidental damage, greatly improving the durability of the joint.

[0058] The connection between the guardrail 310 and the fixed socket 100 ensures both joint fixation and a compact layout by utilizing the surface space of the vehicle body 300. This connection design reduces the exposure of external joints or interfaces, thereby saving space, avoiding interference from excessive external joints, and optimizing the overall structure of the rail engineering vehicle.

[0059] This compact design allows the electrical connection system to be better integrated into the structure of the vehicle body 300, avoiding taking up too much extra space and improving the overall usability and appearance of the vehicle body 300.

[0060] The 310 railing not only effectively prevents people or objects from colliding with the electrical connectors, but also prevents external debris (such as dust and moisture) from directly contacting the connectors to a certain extent, reducing the possibility of connector failure due to contamination.

[0061] Workflow: First, activate the reinforcement component 200, allowing it to relax. Then, insert the PCE electrical connector on the vehicle body 300 into the insertion cavity 110 of the fixed socket 100, ensuring a tight fit. Next, rotate the lever arm 220, causing the pressure plate 230 to abut against the edge of the PCE electrical connector; then, rotate the lever arm 220 in the opposite direction, automatically locking it as the compression spring is compressed, thus reinforcing the connection between the fixed socket 100 and the PCE electrical connector. This ensures the PCE electrical connector is securely locked, guaranteeing stability and preventing loosening during connection.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
