DETAILED DESCRIPTION

[0028] See also Figures 1 to 7In an embodiment of the present invention, a durable and protective automotive front combination lamp wiring harness includes a connecting base 1, a terminal head 2, a connecting wire 3, a clamping rod mechanism 4, a push ring mechanism 5, and a torsion ring 6, wherein the connecting wire 3 is fixedly connected to the terminal head 2, the terminal head 2 can be slidably engaged with the connecting base 1, the clamping rod mechanism 4 is slidably and rotatably provided in the terminal head 2, the push ring mechanism 5 is slidably provided in the terminal head 2, and the torsion ring 6 is sealingly rotatably provided on the terminal head 2;

[0029] The clamping rod mechanism 4 includes a clamping ring 41, a clamping plate 42 and a T-shaped rod 43, wherein an annular groove is provided in the terminal head 2, and the clamping ring 41 is rotatably and slidably arranged in the annular groove. One end of the clamping ring 41 is fixedly provided with a plurality of clamping plates 42 in a circumferential manner, and the other end is fixedly provided with a plurality of T-shaped rods 43 in a circumferential manner. The T-shaped rods 43 protrude from the terminal head 2, and the terminal head 2 is provided with a sliding groove for the T-shaped rods 43 to slide.

[0030] The connecting base 1 is provided with a connecting groove 11, in which a plurality of fixing blocks 12 are fixedly arranged in a circumferential manner. Two clamping blocks 13 with an inclined surface are fixedly arranged on the fixing blocks 12, and a clamping groove is provided between the clamping blocks 13 and the fixing blocks 12. The T-shaped rod 43 can slide along the inclined surface of the clamping block 13 and be clamped into the clamping groove;

[0031] The connecting seat 1 is provided with an annular limiting groove, in which a limiting ring 14 is provided for limiting sliding. A plurality of springs 141 are fixedly provided between the limiting ring 14 and the connecting seat 1. A plurality of push blocks 142 are fixedly provided in a circumferential manner on the limiting ring 14. The push blocks 142 are located between two adjacent fixed blocks 12 and slide along between the two fixed blocks 12.

[0032] The terminal head 2 is provided with a plurality of push blocks 21 fixedly arranged in a circumferential manner, and the push blocks 21 can push the push block 142 to slide;

[0033] The terminal head 2 is provided with a plurality of deflection slots 22 in a circumferential manner. A strip plate 23 is slidably disposed in the deflection slot 22. A plurality of springs 24 are disposed between the strip plate 23 and the terminal head 2. The clamping plate 42 is slidably and rotatably disposed in the deflection slot 22, and the clamping plate 42 is slidably connected to the strip plate 23.

[0034] The push ring mechanism 5 includes an annular plate 51, a push rod 52 and a push ring 53, wherein an outer sleeve 25 is fixedly provided on the terminal head 2, and a sealing ring 26 is provided at one end of the outer sleeve 25 close to the connecting seat 1. The sealing ring 26 has an inclined surface, and the annular plate 51 is slidably provided in the outer sleeve 25. A plurality of push rods 52 are fixedly provided on the annular plate 51 in a circumferential manner. A push ring 53 is fixedly provided at the output end of the push rod 52, and the push ring 53 can slide along the inclined surface of the sealing ring 26;

[0035] The bottom of the annular plate 51 is provided with a plurality of annular grooves 511;

[0036] A plurality of push rods 421 are fixedly provided on the circumference of the clamping ring 41 . The push rods 421 are inserted into the annular groove 511 and slide along the annular groove 511 . A rectangular groove is provided on the terminal head 2 for the push rods 421 to slide and rotate.

[0037] In particular, when the terminal head 2 is connected to the connecting seat 1, the push rod 421 is close to one end of the annular groove 511, and when the T-shaped rod 43 drives the retaining ring 41 to rotate, the push rod 421 will slide toward the other end of the annular groove 511, that is, when the T-shaped rod 43 rotates, the torsion ring 6 will not rotate, and when the torsion ring 6 rotates, the push rod 421 is pressed against one end of the annular groove 511, so the torsion ring 6 can drive the retaining ring 41 to rotate.

[0038] During implementation, align the wiring head 2 with the connecting seat 1, and then push the wiring head 2 to slide and clamp it on the connecting seat 1. During this process, the pushing block 21 and the T-bar 43 will be clamped in the connecting groove 11, and the pushing block 21 will push the pushing block 142 to slide, and make the limiting ring 14 compress the spring 141. At the same time, the T-bar 43 will slide along the inclined surface of the clamping block 13 under the action of thrust, thereby making the clamping ring 41 rotate, and the rotation of the clamping ring 41 further drives the clamping plate 42 to rotate, and the rotation of the clamping plate 42 further pushes the strip plate 23 to rotate along the deflection groove 22 and compress the spring 2 24. Then, when the T-bar 43 slides to disengage from the clamping block 13, The clamping block 13 no longer restricts the T-bar 43, and the clamping plate 42 will rotate under the thrust of the spring 24, and drive the clamping ring 41 and the T-bar 43 to rotate, so that the T-bar 43 is stuck in the clamping groove, thereby making the terminal head 2 and the connecting seat 1 clamped together, and then the terminal head 2 is released. At this time, the pushing block 21 no longer has thrust, and the limiting ring 14 will slide under the thrust of the spring 141, and push the pushing block 142 to slide, and further push the pushing block 21 and the terminal head 2 as a whole to slide away from the end of the connecting seat 1. In this process, since the T-bar 43 is stuck in the clamping groove, the T-bar 43, that is, the clamping rod mechanism 4, will not slide. The shaped plate 51 will not slide under the action of the push rod 421 and the annular groove 511. At this time, due to the sliding of the terminal head 2, the outer sleeve 25 will slide together and drive the sealing ring 26 to slide toward the end away from the connecting seat 1. Since the annular plate 51, that is, the entire push ring mechanism 5, will not slide, the push ring 53 will slide along the inclined surface of the sealing ring 26 and squeeze the sealing ring 26 during the sliding process, so that the sealing ring 26 is tightly attached to the connecting seat 1, thereby achieving the sealing between the connecting seat 1 and the terminal head 2, preventing the terminal head 2 from entering the water and short-circuiting. The separation of the terminal head 2 from the connecting seat 1 requires that the T-bar 43 be disengaged from the slot, and the T-bar 43 must be rotated to be disengaged from the slot. Therefore, when the vehicle is bumpy during driving, the connection between the terminal head 2 and the connecting seat 1 will not loosen, and during the bumping process, the connecting line 3 will pull the terminal head 2, so that the terminal head 2 has a force to separate from the connecting seat 1. At this time, the terminal head 2 will be displaced on the connecting seat 1. During this process, since the push ring mechanism 5 always remains stationary, the push ring 53 will slide along the inclined surface of the sealing ring 26 until the push ring 53 completely presses against the end of the sealing ring 26. As the push ring 53 slides along the inclined surface of the sealing ring 26, the extrusion force on the sealing ring 26 will become greater and greater, so that the sealing ring 26 will be closer to the connecting seat 1, and the more the terminal head 2 and the connecting seat 1 are pulled, the tighter the connection will be.This prevents the connection head 2 from being disconnected from the connection base 1. When the connection base 1 and the connection head 2 need to be loosened, the connection head 2 is first pushed to slide, so that the push ring 53 disengages from the sealing ring 26, that is, the sealing ring 26 is no longer tightly attached to the connection base 1. Then, the torsion ring 6 is rotated to rotate the protrusion 61 and drive the annular plate 51 to rotate. The rotation of the annular plate 51 further drives the push rod 421 to rotate and drives the snap ring 41 to rotate, thereby disengaging the T-bar 43 from the slot. Then, the connection head 2 can be pulled off the connection base 1. At the same time, the torsion ring 6 is loosened to restore the snap ring 41 and the annular plate 51. This makes the connection and disassembly of the connection head 2 and the connection base 1 more convenient, the connection more stable, and the waterproof performance better.

[0039] In this embodiment, a plurality of protrusions 61 are fixedly provided on the torsion ring 6 in a circumferential manner;

[0040] A plurality of rectangular grooves 512 are circumferentially formed on the top of the annular plate 51 , and the protrusions 61 are slidably disposed in the grooves 512 .

[0041] In particular, the groove 512 is provided so that when the terminal head 2 drives the torsion ring 6 to slide, the protrusion 61 can slide along the groove 512 at the same time, so that the torsion ring 6 drives the annular plate 51 to rotate without being affected by the sliding of the torsion ring 6.

[0042] In this embodiment, the connection base 1 is provided with a plurality of plug holes 15;

[0043] A plurality of plug rods 27 are fixedly provided on the wiring head 2 , and the plug rods 27 can be slidably inserted into the plug holes 15 .

[0044] To sum up, when the present invention is implemented, the connection between the terminal head 2 and the connecting seat 1 is more stable through the setting of the clamping rod mechanism 4 and the push ring mechanism 5, and there is no risk of loose connection or even water ingress due to vehicle bumps. At the same time, an outer sleeve 25 is provided on the outside of the terminal head 2, and a sealing ring 26 is provided on the outer sleeve 25. Through the cooperation of the sealing ring 26 with the push ring mechanism 5 and the clamping rod mechanism 4, after the terminal head 2 and the connecting seat 1 are connected, the sealing ring 26 can be tightly attached to the connecting seat 1, thereby realizing a sealed connection between the terminal head 2 and the connecting seat 1 and improving its waterproof performance. Moreover, when the vehicle is bumpy during driving, which causes tension to be generated between the terminal head 2 and the connecting seat 1, the sealing ring 26 will be tightened on the connecting seat 1 as it is pulled, further making the connection between the connecting seat 1 and the terminal head 2 more stable.

[0045] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
