[0022] The rotating connecting member includes two clamping blocks 21 respectively fixedly mounted on the outer wall of one side of the U-shaped clamp 5, and the two clamping blocks 21 are rotatably mounted with the rotating shaft 20 inside. The two rotating shafts 20 are fixedly provided with connecting blocks 19 outside. The two sets of connecting blocks 19 are connected to the first protective shell 9 at one side away from the rotating shaft 20. Reference Manual Attached Figure 3 It can be seen that the clamping block 21 can mount the rotating shaft 20 to one side of the U-shaped clamp 5 , and the first protective shell 9 can be turned over outside the U-shaped clamp 5 through the connecting block 19 and the rotating shaft 20 .

[0023] The first protective shell 9 is rotatably mounted with the second protective shell 13 at both ends of the side away from the connecting block 19 through the correspondingly installed rotating seats 22. The inner surface of the second protective shell 13 is provided with suction members on both sides. The suction members include an iron-absorbing block 8 fixedly arranged on one side of the inner surface of the second protective shell 13. The outer wall of the U-shaped clip 5 and the corresponding position of the iron-absorbing block 8 are provided with magnetic blocks 6. The magnetic blocks 6 are magnetically connected to the iron-absorbing block 8. Reference Manual Attached Figure 1 , Figure 2 , Figure 4 , Figure 5 It can be seen that under the magnetic connection between the magnetic block 6 and the magnetic absorption block 8, the second protective shell 13 closes the U-shaped clip 5, so that the first protective shell 9 and the second protective shell 13 are mounted on the connection between the terminal shell 1 and the split shell 2 for protection.

[0024] The wire fixing assembly includes an L-shaped strip 4 fixedly arranged at one end of the outer side of the U-shaped clip 5, a clamping strip 7 is arranged on the outer side of the L-shaped strip 4, a sliding member is arranged on the outer side of the clamping strip 7, and the sliding member includes a sliding seat 12 slidably installed on the outer side of the clamping strip 7, a connecting plate 14 is fixedly arranged on the outer side of the sliding seat 12, and elastic members are arranged on both sides of the connecting plate 14; Reference Manual Attached Figure 6It can be seen that the slide seat 12 and the connecting plate 14 can drive the elastic member to move outside the clamping strip 7, and then clamp the wiring harness 3 at the end away from the terminal housing 1 and the split housing 2.

[0025] The elastic member includes a clamping rod 17 fixedly arranged on one side of the connecting plate 14, a slider 11 is slidably mounted on the outer side of the clamping rod 17, the slider 11 is made of rubber material, an arc groove adapted to fit the clamping wire harness 3 is provided inside the slider 11, a stripping member is provided inside the slider 11, a spring 18 is sleeved on the outer side of the clamping rod 17 and one end close to the slider 11, and the outer side of the slider 11 abuts against the spring 18; Reference Manual Attached Figure 1 , Figure 2 and Figure 6 It can be seen that after the slider 11 is clamped, the spring 18 elastically returns to its original position, and the two groups of sliders 11 can be clamped against the surface of the wire harness 3. In addition, the slider 11 is made of rubber material, which increases the friction resistance between the slider 11 and the surface of the wire harness 3, and also limits the position of the slider 12, thereby ensuring that the slider 12 will not move again after the wire is clamped.

[0026] The peeling member includes an arc-shaped knife 16 slidably mounted inside the slider 11. The slider 11 has a slide groove 15 on its surface. A bolt 26 is inserted inside the arc-shaped knife 16. The bolt 26 slides inside the slide groove 15. A nut 25 is threadedly connected to the outside of the bolt 26. Reference Manual Attached Figure 6 and Figure 7 It can be seen that when the wire is clamped, the two sets of sliders 11 are in contact with the surface of the wire harness 3. In order to avoid scratching the skin of the wire harness 3, the arc knife 16 can be retracted to the other end of the slide groove 15. When stripping the wire is required, the arc knife 16 can be pushed to fit the surface of the wire harness 3, and then it can be clamped against the skin of the wire harness 3 by squeezing. Then the wire harness 3 is rotated one circle to peel off the skin. When the wire harness 3 is connected, a stripping tool can be provided for quick use. It should be specially noted that the opening distance of the slide groove 15 allows the two sets of arc knives 16 to be close to each other to strip the wire harness 3.

[0027] The clamping member includes a rotating rod 27 rotatably mounted at one end of the rubber clamp 10, a movable cylinder 24 is fixedly sleeved on the outside of the rotating rod 27, a sliding rod 23 is slidably inserted at one end of the rubber clamp 10 away from the rotating rod 27, a convex ring is provided at the end of the sliding rod 23, and one end of the sliding rod 23 is movably clamped in the movable cylinder 24; Reference Manual Attached Figure 5 and Figure 8 It can be seen that the rotating rod 27 can make the movable cylinder 24 turn up and down at one end of the rubber clamping block 10, so as to avoid blocking the wiring harness 3 when it is clamped against the wiring harness 3; A sliding slide rod 23 is provided at the opposite end of the rubber clamping block 10. After the wiring harness 3 is clamped, the slide rod 23 can be slidably inserted into the inside of the flipped movable cylinder 24. The movable cylinder 24 can be made of flexible materials such as rubber. The slide rod 23 can be stably clamped in the inside of the movable cylinder 24 with the help of an external convex ring, and then encapsulated at an opening on one side of the rubber clamping block 10.

[0028] Working principle: When in use, firstly, the terminal shell 1 and the split shell 2 are elastically sleeved, and the conductive terminals inside the terminal shell 1 are inserted into the conductors of the socket, thereby promoting the use of the connector, and then the U-shaped clip 5 and the sliders 11 separated at both ends are clamped against the outer surfaces of the terminal shell 1 and the split shell 2 corresponding to the wiring harness 3, and the U-shaped clip 5 is clamped by the rubber clamp block 10, and the two groups of separate sliders 11 squeeze the springs 18 outside the corresponding clamping rods 17 to allow the wiring harness 3 to be filled between the two groups of sliders 11, and the springs 18 are reset, and the sliders 11 are tightly attached to the outer surface of the wiring harness 3. In this way, the connection is made on the wiring harness 3, thereby avoiding the connector from being stuck. When suspended, the terminal shell 1 and the split shell 2 are weakened in elasticity of the clamping structure therebetween due to the falling of the wiring harness 3, resulting in unstable connector connection. After the fixed wire structure is connected, the first protective shell 9 and the second protective shell 13 are flipped to the outside of the terminal shell 1 and the split shell 2 through the connecting block 19 and the rotating shaft 20, thereby protecting their connection to prevent the terminal shell 1 and the split shell 2 from contacting with hard objects and damaging the outer shell when suspended and shaking. The second protective shell 13 is magnetically attracted to the magnetic block 6 at the U-shaped clip 5 through the magnetic block 8 on the inner surface, thereby enabling the first protective shell 9 and the second protective shell 13 to be stably assembled and used.
