Compared to ordinary charging cables, they can withstand higher current intensities, significantly shortening charging time and improving the user's charging experience. These cables typically possess excellent flexibility, facilitating easy movement and storage in various scenarios. The outer layer uses wear-resistant and high / low temperature-resistant materials, adapting to complex outdoor environments and frequent usage demands. They also balance insulation performance and mechanical strength, effectively preventing safety hazards such as leakage and short circuits. Widely used in public fast charging stations, battery swapping stations, and home fast charging scenarios for new energy vehicles, they provide strong support for the rapid popularization of new energy vehicles.

[0003] In the assembly process of liquid-cooled fast charging cable connectors, traditional clamps are often difficult to adapt to different specifications of connectors due to their fixed structure. During clamping, loose contact or excessive compression may occur, resulting in insufficient assembly stability and affecting the connection quality of the connectors. In addition, the manual adjustment process is cumbersome, increasing operation time and labor intensity. Furthermore, different connectors have large differences in shape, and ordinary clamps lack flexible adjustment capabilities, which can easily cause positioning deviations, reduce assembly efficiency, and fail to meet the requirements of efficient and precise assembly. Therefore, a connector assembly clamp for liquid-cooled fast charging cables is needed. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a connector assembly fixture for a liquid-cooled fast-charging cable, wherein:

[0027] The top frame 1, as the basic load-bearing component of the entire mechanism, is made of high-strength alloy material to ensure structural stability. Its interior provides installation space for the motor 6 and the bidirectional screw 7, and its surface provides a sliding track for the slider 8. It is fixedly connected to the bracket 2 on both sides, and a hydraulic cylinder 14 is installed at the bottom to provide a stable support platform for the coordinated work of various components.

[0028] The motor 6 is fixedly connected inside the top frame 1. As a power source, it outputs torque to drive the bidirectional screw 7 to rotate. The rotation direction of the bidirectional screw 7 is controlled by the forward and reverse rotation of the motor 6, thereby realizing the sliding of the slider 8 in opposite directions. This provides power support for the operation of the entire adaptive adjustment mechanism and ensures stable power during the adjustment process.

[0029] The bidirectional screw 7 is rotatably connected inside the top frame 1, and two sliders 8 are threaded onto its outer surface. When the motor 6 drives it to rotate, the two sliders 8 are driven to slide synchronously along the track on the surface of the top frame 1 by using the thread transmission principle. The rotational power of the motor 6 is converted into the linear motion of the sliders 8 through the helical motion of the screw, thus realizing power transmission.

[0030] The slider 8 is slidably connected to the surface of the top frame 1 and threaded onto the outer surface of the double-acting screw 7. The bottom is rotatably connected to the connecting rod 9. When the slider 8 slides under the drive of the double-acting screw 7, it pushes the connecting rod 9 to adjust the angle through its own position change, converting the linear motion into the swing motion of the connecting rod 9, thereby realizing the transmission of force and the conversion of direction.

[0031] The connecting rod 9 is rotatably connected to the bottom of the corresponding slider 8 and the connecting piece 12. It swings under the push of the slider 8 and changes the position and angle of the connecting piece 12 by its own constant length. The power of the slider 8 is smoothly transmitted to the connecting piece 12, which drives the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 to move, ensuring a smooth transmission process.

[0032] The connector 12 is rotatably connected to the bottom of the connecting rod 9 and fixedly connected to the first arc-shaped clamp 10 and the second arc-shaped clamp 11 respectively. Under the drive of the connecting rod 9, the position and angle are adjusted, and the swing motion of the connecting rod 9 is converted into the opening and closing action of the first arc-shaped clamp 10 and the second arc-shaped clamp 11, which plays the role of a bridge for connection and power transmission.

[0033] The first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 are rotatably connected to the connecting bracket 13 and open and close under the action of the connecting piece 12. Wear-resistant and non-slip material is used to increase the friction with the cable connector. The arc-shaped design is adapted to different specifications of connectors to ensure stable and reliable clamping process and avoid connector slippage or damage.

[0034] The connecting bracket 13 is fixedly connected to both sides of the surface of the top frame 1, providing a rotation fulcrum for the first arc-shaped clamp 10 and the second arc-shaped clamp 11, restricting their movement trajectory, enhancing the stability and accuracy of the clamp's movement, making the clamp opening and closing process smoother, and ensuring the clamping and positioning accuracy of the cable connector.

[0035] The hydraulic cylinder 14 is fixedly connected to the bottom of the top frame 1, and its output end is fixedly connected to the auxiliary positioning component 15. The auxiliary positioning component 15 is moved up and down by hydraulic drive to achieve pre-positioning and auxiliary support of the cable joint, increase the contact area with the joint, and further improve the stability of the assembly process.

[0036] The auxiliary positioning component 15 is an arc-shaped or triangular positioning plate that contacts the cable connector under the drive of the hydraulic cylinder 14. It adapts its shape to different connector contours to achieve precise pre-positioning. It uses lightweight and high-strength materials to reduce the load on the mechanism and enhance positioning stability, providing a foundation for subsequent clamping actions.

[0037] The bracket 2 is fixedly connected to both sides of the top frame 1 and slidably connected in the slide groove of the side plate 3. Under the drive of the electric push rod 5, it slides up and down along the slide groove, driving the top frame 1 and the upper components to adjust the height. The rigid structure ensures the support strength, making the height adjustment process smooth and reliable, and adapting to the needs of different assembly scenarios.

[0038] The bottom of the side plate 3 is fixedly connected to the bottom plate 4, and the surface is fixedly connected to the electric push rod 5 and has a sliding groove for the bracket 2 to slide. It provides a sliding track for the bracket 2 and supports the electric push rod 5. It is made of corrosion-resistant material to extend its service life. The sliding groove guides the bracket 2 to ensure accurate sliding direction and ensure height adjustment accuracy.

[0039] The base plate 4 is fixedly connected to the bottom of the side plate 3. It is made of a heavy and stable material to increase the overall stability of the mechanism, provide bottom support for the entire device, and prevent shaking or tipping during assembly. At the same time, it increases the contact area with the ground, disperses pressure, and enhances the stability of the mechanism.

[0040] The output end of the electric push rod 5 is fixedly connected to the bracket 2. Through the telescopic action, the bracket 2 is driven to slide in the slide groove of the side plate 3, converting electrical energy into mechanical energy to realize the height adjustment of the top frame 1. It has the characteristics of high adjustment accuracy and stable operation, reducing manual operation and improving the automation and efficiency of height adjustment.

[0041] Working principle: The motor 6 starts and drives the bidirectional screw 7 to rotate, causing the two sliders 8 to slide on the surface of the top frame 1. The sliders 8 drive the connecting rod 9 to move. The connecting rod 9 drives the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 to rotate on the connecting bracket 13 through the connecting piece 12 to realize opening and closing, so as to accommodate different specifications of cable joints. At the same time, the hydraulic cylinder 14 at the bottom of the top frame 1 pushes the auxiliary positioning component 15 (arc or triangular positioning plate) to descend and assist in positioning the cable joint, further increasing the contact area and improving stability. The brackets 2 on both sides of the top frame 1 slide in the grooves of the side plate 3. The bottom plate 4 at the bottom of the side plate 3 provides stable support. The electric push rod 5 extends and retracts, causing the side plate 3 and the bracket 2 to move relative to each other, adjusting the height of the top frame 1 to clamp and fix the cable joint. The two mirror-set adaptive adjustment mechanisms work together to ensure that the cable joint is stably clamped and accurately positioned during the assembly process.

[0042] Example 1: (Reference) Figure 1-2 )

[0043] The auxiliary positioning component 15 adopts an arc-shaped positioning plate. When clamping a cable connector with a circular cross-section, the arc-shaped positioning plate of the auxiliary positioning component 15 can form a large-area fit with the outer circular surface of the connector. The positioning pressure is distributed by the complementary curved surface, avoiding the deformation of the connector caused by excessive local force. At the same time, the arc-shaped contour can guide the connector to quickly enter the center positioning position, reducing manual alignment time. It is made of wear-resistant elastic material, which can produce slight deformation when in contact, further enhancing the fit and anti-slip effect.

[0044] The auxiliary positioning component 15 can be replaced with a triangular positioning plate. The auxiliary positioning component 15 in the form of a triangular positioning plate forms a three-point contact with the outer surface of the circular connector through three vertices. It uses the inherent stability of the triangle to limit the radial sway of the connector. Moreover, the small contact area of ​​the vertices can adapt to the situation where there are slight protrusions or textures on the surface of the connector, and avoids the impact of uneven surface on positioning accuracy. The material is made of high-strength engineering plastic, which has both hardness and toughness, and extends the structural stability during use.

[0045] Example 2: (Reference) Figure 3 and Figure 4 )

[0046] The top frame 1 not only serves as a load-bearing foundation, but also constrains the sliding trajectory of the slider 8 through surface grooves, ensuring the synchronous movement of the slider 8 when the bidirectional screw 7 is driven. The brackets 2 connected on both sides of the top frame bear the load-bearing function of height adjustment.

[0047] Motor 6 controls the direction of bidirectional screw 7 by forward and reverse rotation. Forward rotation causes slider 8 to slide towards each other, driving the clamp to close. Reverse rotation causes slider 8 to slide in the opposite direction, thus opening the clamp. The same power source achieves two opposite actions.

[0048] When the electric push rod 5 extends or retracts, it pushes the bracket 2 to slide in the slide groove of the side plate 3. When it rises, it raises the top frame 1 and the clamping components to adapt to the high position assembly. When it falls, it lowers the height to facilitate low position operation. The same structure realizes bidirectional height adjustment.

[0049] The connecting bracket 13 provides a fulcrum for rotation of the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11, and also prevents excessive rotation of the clamping plates through a limiting function, thus ensuring safe and stable clamping action.

[0050] Example 3: (Reference) Figure 1-4 )

[0051] In the scenario of a fast charging station for new energy vehicles, the base plate 4 is fixed on the ground, and the electric push rod 5 extends to drive the bracket 2 to rise along the slide groove of the side plate 3, so that the top frame 1 and the clamping components are at a suitable height to match the docking position of the charging pile and the vehicle connector.

[0052] Motor 6 drives bidirectional screw 7 to rotate, and slider 8 drives connecting rod 9 to open the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11. After the cable connector is inserted, motor 6 rotates in the opposite direction to complete the clamping. Hydraulic cylinder 14 pushes auxiliary positioning component 15 to assist in fixing, thereby improving the assembly efficiency of fast charging connector.

[0053] In the workshop production and assembly scenario, the base plate 4 is installed on the assembly line workbench, and the electric push rod 5 is shortened to lower the height of the top frame 1, making it easier for workers to operate at close range. The auxiliary positioning component 15 uses an arc-shaped positioning plate to pre-position batch of circular joints.

[0054] Two mirror-mounted adaptive adjustment mechanisms clamp the two ends of the connector respectively, ensuring the coaxiality of the connector through synchronous action, reducing manual alignment errors, and meeting the high-efficiency assembly needs of mass production in the workshop.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
