[0002] New energy vehicle cables are cables specially designed and manufactured for electric vehicles and other new energy vehicles. They are used to connect batteries, motors, control systems, charging piles and other equipment. New energy vehicle cables play a vital role in the power transmission and power management of electric vehicles, ensuring the safety and performance of the vehicles.

[0003] For example, a utility model with publication number CN220106070U relates to the field of cable technology.

A plurality of annular grooves are evenly distributed on the outer wall of the protective sleeve. The cable main body can be protected by the protective sleeve to avoid wear of the cable main body during vehicle driving, thereby improving the protection effect and wear resistance of the cable main body. The connecting block is rubber and has a certain elasticity, so it can absorb energy when the vehicle is running and bumps and vibrates, reduce the vibration of the cable main body, and reduce wear. A plurality of empty grooves are formed between the connecting blocks, which can increase the gap between the cable main body and the protective sleeve, reduce material consumption during production, and improve the heat dissipation effect.

[0004] When the above device is in use, the heat dissipation effect of the cable is improved by setting components such as a protective cover and a U-shaped clamp. However, since the above device is mainly optimized with the cable as the main body, when multiple cables are assembled, they can generally only be connected by welding. Moreover, since the copper core inside the cable of the above device is not fixed, the operator also needs to position the copper core during welding to prevent it from shifting during the assembly process, resulting in loose connection between the cables, thereby increasing the complexity and time cost of cable assembly, and making it inconvenient to assemble multiple cables. Therefore, a new energy vehicle cable that is easy to assemble is proposed to solve the problems raised in the background technology. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the present invention provides a new energy vehicle cable that is easy to assemble, including a cable body 1, two ends of the cable body 1 are respectively fixedly connected with a first connector 2 and a second connector 3, the first connector 2 and the second connector 3 are both threadedly connected to a threaded rod 4 on one side opposite to the other, and a convex rod 5 is provided on the inner wall of the threaded rod 4 in an annular manner at ninety degrees, the first connector 2 and the second connector 3 are both movably connected to a rotating drum assembly 6, the first connector 2 and the second connector 3 are both movably connected to an arc plate 8 in an annular manner at ninety degrees, and the arc plate 8 is fixedly connected to a first round rod 7 on one side close to the rotating drum assembly 6, a plurality of cable cores 10 are provided inside the cable body 1, and the first connector 2 and the second connector 3 are respectively movably connected to an inclined block 11 and a square plate 13 in an annular manner at ninety degrees inside the opposite ends; The drum assembly 6 includes a drum body 601 , and a first guide groove 603 is provided in a circular shape at a 90-degree angle on one side of the drum body 601 away from the threaded rod 4 .

[0027] The above scheme is adopted: the convex rod 5 is circumferentially limited by the first straight groove 602, so that the threaded rod 4 can drive the drum body 601 to rotate when it rotates, and the arc plate 8 is driven to move toward the cable core 10 through the first round rod 7 when the drum body 601 rotates, so that the gasket 9 is abutted against the outer wall of the cable core 10, and a circle is formed after the gasket 9 moves, so that it is convenient to wrap several cable cores 10, and then the gasket 9 is made of rubber material, so as to create resistance to the cable core 10, so as to facilitate the positioning of the cable core 10, and at the same time, the rubber material can also prevent current short circuit, thereby improving the assembly efficiency of the cable, and at the same time, it can also improve the stability of the system operation.

[0028] like Figure 1 to Figure 2 , Figures 5 and 6 As shown, the first connector 2 and the second connector 3 are in a plug-in structure, and one side of the inclined block 11 is fixedly connected with a spring piece 12 fixed to the first connector 2. The spring piece 12 is used to squeeze the inclined block 11 and keep the inclined block 11 moving toward the outside of the first connector 2. The end of the inclined block 11 away from the spring piece 12 is in a slope shape. The inclined block 11 passes through the outer wall of the first connector 2 and extends to the outside of the first connector 2. After the first connector 2 is inserted into the second connector 3, it will abut against the slope of the inclined block 11 and squeeze the inclined block 11 to move in the direction of the spring piece 12.

[0029] The above scheme is adopted: a second guide groove 15 is opened on the surface of the drum body 601 located inside the second connector 3, so that when the drum body 601 rotates, the second round rod 14 cooperates with the second guide groove 15 to drive the square plate 13 to move toward the inside of the square groove, and the inclined block 11 is inclined, so that it is convenient to squeeze the inclined block 11 and shrink it to the inside of the first connector 2. Through the design of the spring piece 12, when the position of the inclined block 11 coincides with the square groove, the inclined block 11 will move toward the inside of the square groove under the action of the elastic force of the spring piece 12, thereby fixing the position of the first connector 2, thereby facilitating the assembly and connection of the two cable bodies 1.

[0030] like Figure 2 , Figures 5 and 6 As shown, a second round rod 14 is fixedly connected to one side of the square plate 13 close to the drum assembly 6, and a second guide groove 15 is provided in a ring shape at 90 degrees on the surface of the drum body 601 inside the second connecting head 3. The second guide groove 15 and the first guide groove 603 have the same orientation, and a square groove is provided in a ring shape at 90 degrees on the inner wall of the second connecting head 3. The square plate 13 is located inside the square groove. The square plate 13 seals the square groove in the initial state, and the second round rod 14 is movably clamped inside the second guide groove 15.

[0031] The above scheme is adopted: the square groove is sealed by the square plate 13 in the initial state. Its function is that when the two cable bodies 1 need to be disassembled, the operator rotates the threaded rod 4 in the opposite direction, thereby driving the rotating drum assembly 6 to rotate in the opposite direction through the convex rod 5, and then the second round rod 14 moves in the opposite direction along the trajectory of the second guide groove 15, thereby driving the square plate 13 to reset. While the square plate 13 is reset, the inclined block 11 is squeezed, thereby pushing the inclined block 11 to move in the direction of the spring piece 12. When the square plate 13 re-seals the square groove, the inclined block 11 is completely retracted into the inside of the first connector 2, thereby releasing the first connector 2 from the fixation with the other second connector 3, thereby facilitating the disassembly of the two cable bodies 1.

[0032] like Figures 2 to 4 As shown, the outer wall of the drum body 601 away from the first guide groove 603 is provided with a first straight groove 602 at 90 degrees, and the protruding rod 5 is movably clamped in the inside of the first straight groove 602. The first straight groove 602 is used to limit the protruding rod 5 circumferentially. The two threaded rods 4 respectively penetrate the outer walls of the first connector 2 and the second connector 3 and extend to the outside of both. When the threaded rod 4 rotates, the drum body 601 is driven to rotate through the protruding rod 5, and the protruding rod 5 slides in the inside of the first straight groove 602. The first round rod 7 is movably clamped in the inside of the first guide groove 603. The inner walls of the first connector 2 and the second connector 3 A second straight groove 604 is provided for circumferentially limiting the first round rod 7. When the drum body 601 rotates, the first round rod 7 is driven to move toward the cable core 10 through the first guide groove 603. A gasket 9 is fixedly connected to the side of the arc plate 8 close to the cable core 10. The gasket 9 is made of rubber material. After the first round rod 7 moves, the gasket 9 is driven to abut against the outer wall of the cable core 10 through the arc plate 8. After the four gaskets 9 move, a circle is formed. A limiting groove matching the second round rod 14 is provided on the inner wall of the second connecting head 3. When the drum body 601 located in the second connecting head 3 rotates, it drives the second round rod 14 to move toward the inside of the square groove.

[0033] The above scheme is adopted: the gasket 9 is made of rubber material, and its function is that since the rubber material has good friction and elasticity, when the gasket 9 abuts against the outer wall of the cable core 10, a large friction force will be generated between the two, and then the gasket 9 will generate resistance to the cable core 10, so that the cable core 10 cannot move, thereby preventing the cable core 10 from loosening and shifting during long-term use, thereby maintaining the stable operation of the cable system. At the same time, rubber is also a good insulating material. Therefore, the gasket 9 can effectively isolate the cable core 10 inside the cable body 1 from the external environment, thereby preventing current leakage or short circuit, and ensuring the safe operation of the cable system.

[0034] The working principle and use process of the present invention are as follows: the operator rotates the threaded rod 4, thereby driving the four protruding rods 5 thereon to rotate, and then the first straight notch 602 limits the circumferential position of the protruding rod 5, so that the protruding rod 5 slides inside the first straight notch 602 when rotating, and drives the rotating drum body 601 to rotate through the first straight notch 602. When the rotating drum body 601 rotates, it drives the first round rod 7 to slide along the trajectory of the first guide groove 603, and because the second straight notch 604 limits the circumferential position of the first round rod 7, the first round rod 7 is A round rod 7 slides through the arc plate 8 to drive the gasket 9 to move toward the cable core 10. When the first round rod 7 abuts against the inner wall of the first guide groove 603, the four gaskets 9 form a circle and abut against the outer walls of several cable cores 10 respectively. Then, since the gasket 9 is made of rubber material, it generates friction with the outer wall of the cable core 10, thereby causing resistance, thereby positioning the position of the cable core 10. At the same time, the gasket 9, as an insulating material, can also effectively isolate the cable core 10 from the external environment, thereby preventing current leakage or short circuit. When the drum body 601 inside the second connector 3 rotates, it also drives the second round rod 14 to slide along the track of the second guide groove 15. Since a straight notch for circumferentially limiting the second round rod 14 is provided inside the second connector 3, the second round rod 14 can only drive the square plate 13 to move toward the inside of the square groove when sliding. When the second round rod 14 abuts against the inner wall of the second guide groove 15, the square plate 13 shrinks to the inside of the second connector 3. Afterwards, the operator assembles and connects the two cable bodies 1, so that the first connector 2 is inserted into the interior of the other second connector 3. While the first connector 2 is inserted, the inclined surface of the inclined block 11 is driven to abut against the inner wall of the second connector 3, so that the inclined block 11 is forced to move in the direction of the spring piece 12, and then the inclined block 11 is completely retracted to the interior of the first connector 2. When the first connector 2 is fully inserted into the second connector 3, the position of the inclined block 11 coincides with the position of the square groove. Subsequently, the inclined block 11 moves toward the direction of the square plate 13 under the action of the elastic force of the spring piece 12, thereby being stuck in the interior of the square groove of the second connector 3, and fixing the position of the first connector 2, thereby facilitating the assembly of the two cable bodies 1.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
