[0021] See also Figure 1-Figure 4As shown, the purpose of this embodiment is to provide a high-conductivity quick-plug wiring harness for new energy vehicles, including a first connector 1 and a second connector 2, one side of the first connector 1 and the second connector 2 are fixedly connected with a wiring harness 3, the middle part of the outer side of the first connector 1 is fixedly connected with a limit ring 4, and a limit groove 5 is provided on the surface of the limit ring 4, and the middle part of the outer side of the second connector 2 is fixedly connected with a fixed ring 6, one side of the fixed ring 6 is fixedly connected with a reset spring 7, and one side of the reset spring 7 is fixedly connected with a movable ring 8 that can be compressed, and the outer side of the movable ring 8 is fixedly connected with a contact ring 9 for driving the movable ring 8 to move, and the second connector 2 is provided with a plurality of circular holes 10 in a circumferential manner through the body Evenly distributed and located below the moving ring 8, a ball 11 is rollingly connected inside each circular hole 10, and the bottom end of the ball 11 contacts the limiting groove 5. Multiple sets of slide grooves are arranged on the outside of the second joint 2 and are located below the reset spring 7. A slider 12 for limiting the moving ring 8 is slidably connected inside the slide groove. The top of the slider 12 is fixedly connected to the bottom end of the moving ring 8. The diameter of the ball 11 is slightly larger than the diameter of the circular hole 10. The existing wiring harness 3 connection ports are generally connected in the form of buckles. Because the car will shake during driving, as time goes by, long-term shaking and pulling can easily cause the buckle of the wiring port to be damaged, broken, or the wiring harness 3 to be disconnected. As a result, the wiring port will lose the locking relationship of the buckle, making it easy for the wiring ports to have virtual connections, etc., affecting the normal use of the automobile equipment and having poor stability. Before connection, first adjust the position of the first joint 1 and the second joint 2 so that the limit block 14 and the clamping block 15 are staggered, and then push the contact ring 9 to drive the moving ring 8 to move to the side squeezed by the reset spring 7, so that it leaks out of the circular hole 10, so as to release the limit of the ball 11 inside the circular hole 10. At this time, let the first joint 1 move into the groove 13. Because the diameter of the ball 11 is larger than the diameter of the circular hole 10, when the bottom end of the ball 11 contacts the limit ring 4, it is squeezed to move upward. , so that the first joint 1 moves inside the groove 13, and when the ball 11 moves to the limiting groove 5 with the first joint 1, the extrusion of the moving ring 8 on the reset spring 7 is released, so that the moving ring 8 blocks the cylindrical hole 10, and the ball 11 is stuck in the limiting groove 5 and cannot move, and the connection between the first joint 1 and the second joint 2 is completed, so that even if the device is shaken for a long time, the connection position will not be damaged or broken, affecting the normal use of the automobile equipment. When the connection needs to be released, the moving contact ring 9 also drives the moving ring 8 to move, so that the ball 11 moves upward under the extrusion, and the first joint 1 can be taken out, realizing the quick plugging and unplugging of the device.
[0022] A groove 13 is provided on one side of the second joint 2, and a plurality of groups of limit blocks 14 are fixedly connected inside the groove 13. The same number of blocks 15 as the limit blocks 14 are fixedly connected to the outside of the first joint 1, and a groove with the same shape as the block 15 is provided on one side of each limit block 14. The plurality of groups of limit blocks 14 are located on the inner wall of the groove 13 and are evenly distributed in a circular manner and close to the bottom end of the groove 13. The plurality of groups of blocks 15 are located on the outer side of the first joint 1 close to the limit ring 4 and are evenly distributed in a circular manner. Before the first joint 1 and the second joint 2 are connected, the first joint 1 is rotated so that the plurality of groups of blocks 15 on the outer side of the first joint 1 are connected one by one with the plurality of groups of limit blocks 14 inside the groove 13, so as to further stabilize and reinforce the connection. Even if the shaking amplitude of the car itself will increase when the car drives to a bumpy section, there will be no poor contact at the connection, so that the car will break down during driving, thereby improving the stability and practicality of the equipment and the safety of the personnel.
[0023] Working principle: Before connection, first adjust the position of the first joint 1 and the second joint 2 so that the limit block 14 and the clamping block 15 are staggered, and then push the contact ring 9 to drive the moving ring 8 to move to the side squeezed by the reset spring 7, so that it leaks out of the circular hole 10, so as to release the limit of the ball 11 inside the circular hole 10, and then let the first joint 1 move into the groove 13. Because the diameter of the ball 11 is larger than the diameter of the circular hole 10, when the bottom end of the ball 11 contacts the limit ring 4, it is squeezed to move upward, so that the first joint 1 moves inside the groove 13. When the ball 11 moves to the limit groove 5 with the first joint 1, the squeeze of the moving ring 8 on the reset spring 7 is released, so that the moving ring 8 blocks the cylindrical hole 10, and the ball 11 is stuck in the limit groove 5 and cannot move, and the connection between the first joint 1 and the second joint 2 is completed. , so that even if the device is shaken for a long time, the connection position will not be damaged or broken, affecting the normal use of the automobile equipment. When the connection needs to be released, the moving contact ring 9 drives the moving ring 8 to move, so that the ball 11 moves upward under the squeeze, and the first joint 1 can be taken out, realizing the quick plugging and unplugging of the device. Before the first joint 1 and the second joint 2 are connected, the first joint 1 is rotated so that the multiple groups of card blocks 15 on the outside of the first joint 1 are connected one by one with the multiple groups of limit blocks 14 inside the groove 13, so as to further stabilize and reinforce the connection. Even if the car drives on a bumpy road section, the shaking amplitude of the car itself will increase, and there will be no poor contact at the connection, so that the car will break down during driving, thereby improving the stability and practicality of the equipment and the safety of personnel.
