DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0025] like Figures 1 to 5As shown, a DC charging socket cable for a light truck includes a first connector 1, one end of the first connector 1 is fixedly connected to a positive line 2 and a negative line 3, the ends of the positive line 2 and the negative line 3 away from the first connector 1 are fixedly connected to a second connector 6, one side of the second connector 6 is fixedly connected to a connection terminal 7, a heat shrink tube 4 is fixedly installed on the positive line 2 and the negative line 3, and a positioning tape 5 is also fixedly connected to the positive line 2 and the negative line 3, and a plurality of card blocks 10 are fixedly connected below the positive line 2 and the negative line 3, and a shell 11 is provided below the card block 10, and a card is provided inside the shell 11. The claw 12 is connected to the limit rod 19 for internal rotation. The limit rod 19 is provided with a torsion spring (not shown in the figure) at the connection with the claw 12. One side of the claw 12 is fixedly connected to the first spring 14. The other end of the first spring 14 contacts the interior of the housing 11. A first through slot 15 is provided on the housing 11. A second through slot 18 is provided on both sides of the housing 11. The bottom of the housing 11 is fixedly connected to the slider 9. Two pressing blocks 13 are movably installed inside the slider 9. The bottom of the pressing block 13 is fixedly connected to the limit block 17. The two pressing blocks 13 and the limit block 17 are fixedly connected. There is a second spring 16, and a slide rail 8 is provided on the outer side of the slider 9. A plurality of through holes are provided on both sides of the slide rail 8. The shape of the first through slot 15 is V-shaped. The height of one end of the V-shaped first through slot 15 is lower than the height of the other end of the V-shaped first through slot 15. The side of the limit rod 19 away from the end of the claw 12 slides and is connected to the inside of the first through slot 15. The slide rail 8 is fixedly installed inside the vehicle body. The through hole and the limit block 17 are used in conjunction with each other, and the block 10 and the claw 12 are used in conjunction with each other, so that the wiring harness can be better installed and disassembled, thereby facilitating the maintenance work. The relative position of the slide rail 8 and the slider 9 The mutual cooperation can make the wiring harness more flexible in fixation, which can be increased and reduced according to needs. The modular design allows each structure to be replaced or maintained separately, avoiding the need to disassemble the entire socket line. The sliding slots and plug-in locking devices make installation and removal operations more convenient, reducing maintenance time and tool requirements, especially easier to operate in narrow spaces. The slide rail 8 can allow the socket line to adapt to adjustments in different positions during installation, and has a locking function to avoid loosening in the slide rail 8. In addition, the limit in the slide rail 8 provides an anti-slip function. Even if the vehicle is bumpy, the socket line will not slip out due to vibration.Working process: Install the card block 10 on the wiring harness. When there is an installation requirement, pinch the pressing block 13 at the corresponding position to make the limit block 17 retract inward, so that the slider 9 can smoothly pass through the inside of the slide rail 8 to reach the predetermined position, release the pressing block 13, and the limit block 17 will pop out synchronously and be stuck into the through hole on the side of the slide rail 8 to generate a limit. Then, the card block 10 will clamp its claw 12 into the inside of the claw 12. At this time, the card block 10 pushes the claw 12 to press the first spring 14 to move downward, and the limit rod 19 falls into the first through slot 15. The claw 12 is limited by the first through slot 15 and the second through slot 18. At this time, the wiring harness is installed on the vehicle. When disassembly is required, press the card block 10 to force the limit rod 19 to move to the other side of the first through slot 15. At this time, the claw 12 releases the limit of the card block 10, and the wiring harness can be taken out.

[0026] Furthermore, the cores of the positive wire 2 and the negative wire 3 are both made of a composite core of copper and carbon fiber. The composite core of copper and carbon fiber has the characteristics of strong thermal conductivity and good flexibility. It can not only improve the conductivity and heat dissipation capacity of the wiring harness, but also enhance the overall fatigue resistance. The high conductivity of copper combined with the high strength of carbon fiber can effectively disperse mechanical stress and extend the service life of the wiring harness.

[0027] Furthermore, a flexible polymer of thermally conductive fiber is added to the outside of the positive wire 2 and the negative wire 3 as a sheath. By adding highly thermally conductive nanomaterials such as carbon nanotubes or aluminum oxide nanoparticles to the silicone rubber, it can have a certain thermal conductivity while maintaining good flexibility. This material has both thermal conductivity and vibration resistance, can absorb vibration, and avoid damage to the wiring harness caused by external impact.

[0028] Furthermore, the slider 9 is made of rubber, and the rubber base can make the limit more linear and filter out some vibrations, thereby ensuring the working environment and fixing conditions of the wiring harness.
