[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] See also Figure 1-3 As shown, this embodiment is a lamp harness plug quick assembly sealing structure, comprising:

[0028] A sealing portion, comprising a front sealing head 11;

[0029] The sealing portion further includes a bellows connecting pipe 12 and a rear sealing head 13. One end of the bellows connecting pipe 12 is fixedly connected to the back of the front sealing head 11, and the other end of the bellows connecting pipe 12 is fixedly connected to the back of the rear sealing head 13.

[0030] The bellows connecting tube 12 is used to structurally install the front sealing head 11 and the rear sealing head 13 to form a sealing structure to seal the gap between the wiring harness and the installation housing to prevent dust. The bellows connecting tube 12 can fine-tune its length through its own expansion and contraction characteristics to meet usage requirements.

[0031] A groove is provided in the middle of the front of the rear sealing head 13, and a threading guide hole 21 extends through the groove;

[0032] The groove reduces the weight of the rear sealing head 13 and saves material costs, and provides storage space for the wiring harness.

[0033] The threading guide portion includes a threading guide hole 21, a movable groove 22, and a guide ball 23. The threading guide hole 21 is evenly spaced and extends through the middle of the front sealing head 11, and the movable groove 22 is evenly spaced and opened on both side walls of the guide hole 21. The guide ball 23 is rollingly connected in the middle of the movable groove 22.

[0034] The wire guide hole 21 guides the wire harness and is used to open multiple movable grooves 22. The movable grooves 22 receive the guide balls 23. The multiple guide balls 23 can be used to pass the wire harness out of the sealing structure with low friction.

[0035] Working Principle: The sealing portion is pre-extended and embedded into the opening on the external mounting housing. One end of the lamp harness is sequentially extended into the corresponding wire guide hole 21. Under the action of the applied pushing force, relying on the rolling force between the multiple guide balls 23 and the harness, the one end of the harness is smoothly and quickly moved out of the sealing portion, completing the electrical connection between the circuit board in the external mounting housing.

[0036] In this solution, on the one hand, the sealing part can be telescopically adjusted in length to meet different usage requirements. On the other hand, the threading is guided by multiple guide balls 23, which helps to reduce friction during threading, improve threading efficiency, and reduce work intensity.

[0037] See also Figure 1-3 As shown, this embodiment is based on the above embodiment 1 and further includes a threading limit portion, which includes a limit frame 31 and a limit ring 32. The limit frame 31 is damped and connected to the middle part of the groove, and the limit ring 32 is equidistantly arranged and connected to the middle part of the front of the limit frame 31.

[0038] The limiting frame 31 receives one end of the wire harness leading out of the sealing portion, and cooperates with the limiting ring 32 to limit the structure of the wire harness portion housed in the limiting frame 31 to prevent it from being moved out again;

[0039] The middle portion of the front side of the limiting frame 31 is equidistantly provided with openings, which are arranged opposite to the threading guide hole 21;

[0040] An annular groove is provided on the outer edge of the opening, and one end of the limiting ring 32 is sleeved and connected to the annular groove, and the limiting ring 32 is fixed by magnetic fit at both ends;

[0041] The ring groove is used to install the limit ring 32. The inner width of the ring groove is larger than the width of the limit ring 32. When the limit ring 32 is magnetically attached to the head and tail, friction damping is limited by the inner wall of the ring groove.

[0042] Working principle: After one end of the wire harness passes through the rear sealing head 13, it enters the opening and extends out of the limit frame 31, and can be connected to the circuit board in the external mounting shell;

[0043] After one end of the wiring harness is connected to the circuit board, the excess part of the wiring harness can be stored in the opening on the limiting frame 31, and the position of the limiting ring 32 can be adjusted at the head and tail, and then fixed by magnetic attraction to limit the excess part of the wiring harness stored in the opening;

[0044] This solution helps to improve the applicability and functionality of the structure and meet different usage requirements.
