Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive lighting wiring harness technology, specifically relating to a sealing structure for automotive lighting wiring harnesses. Background Technology
[0002] Automotive wiring harnesses are the main body of automotive circuit networks. Without wiring harnesses, there are no automotive circuits. A wiring harness refers to a connector made of copper, which is first crimped with wires and cables, and then bundled together with an outer plastic and crimped insulator or metal shell to form a connecting circuit element. The wiring harness industry chain includes cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. Wire harnesses are widely used in automobiles, home appliances, computer and communication equipment, and various electronic instruments and meters.
[0003] Therefore, a sealing structure for a vehicle lamp wiring harness, with announcement number "CN204345592U", includes a first sealing ring fixedly installed inside the lamp housing cavity. The outer periphery of the first sealing ring connects to the inner cavity of the lamp housing, and a through hole is provided at its center. It also includes a second sealing ring fitted onto the wiring harness. The outer periphery of the second sealing ring has the same shape as the through hole, and the area of the second sealing ring is larger than the area of the through hole. This utility model has a simple structure, provides a limiting function under pressure, is not easily deformed or broken after use, has strong aging resistance, a long service life, and a very significant sealing effect.
[0004] However, while the aforementioned headlight wiring harness sealing structure provides a good seal between the wiring harness, the first sealing ring, and the second sealing ring, and the second sealing ring can be funnel-shaped to facilitate the passage of the wiring harness and the second sealing ring through the first sealing ring, and it does not easily come loose when the wiring harness is pulled back, the following significant drawbacks still exist during use: Although the wiring harness is sealed and prevented from falling off through multiple sealing rings, the sealing and fixing through multiple sealing rings is a linear seal without sufficient tensile resistance. This makes it easy for the wiring harness to break off from the headlight when subjected to external force, and the wiring harness is relatively weak and prone to falling off. Utility Model Content
[0005] The purpose of this invention is to provide a sealing structure for vehicle lighting wiring harnesses to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a vehicle headlight wiring harness, comprising:
[0007] The wiring harness sealing tube has a lamp housing locking ring on its outside that is threadedly sealed and locked to the lamp housing. The wiring harness sealing tube has a wiring harness positioning tube inside that is positioned after the lamp wiring harness is sealed and clamped. One end of the wiring harness sealing tube is threaded with a wiring harness sealing cap that seals one end of the wiring harness sealing tube.
[0008] The wire harness sealing clamp includes two semi-circular sealing clamps that are combined as a single unit to clamp and seal the wire harness. Each semi-circular sealing clamp has a clamping side with multiple corrugated wire harness positioning grooves for positioning and sealing the wire harness. Each corrugated wire harness positioning groove is equipped with a corrugated sealing sleeve for corrugated clamping and sealing of the wire harness.
[0009] Preferably, one side of the lamp housing locking ring is provided with a threaded locking ring with an external threaded surface for locking with the vehicle lamp housing, so as to facilitate threaded sealing and locking of the wiring harness sealing pipe and the vehicle lamp housing, so as to connect the wiring harness to the lamp board inside the lamp housing.
[0010] Preferably, one end of the wire harness sealing through-pipe is provided with an internal threaded locking groove, and one side of the wire harness sealing locking cover is provided with a locking ring that is locked in the internal threaded locking groove. A positioning block for pressing and positioning the wire harness sealing clamp is movably provided inside the internal threaded locking groove, so that the wire harness is clamped and sealed by the corrugated clamp and the wire harness sealing clamp is pressed and fixed.
[0011] Preferably, the inner side of the wire harness positioning tube is provided with positioning grooves, and the inner side of the other end of the wire harness positioning tube is provided with a limiting support ring that limits and supports one end of the wire harness sealing clamp, so that the wire harness positioning tube can always remain in the initial position after the wire harness is positioned.
[0012] Preferably, the two ends of one side of the semi-circular sealing clamp are provided with combined clamping plates that slide into the positioning clamping groove for combined clamping, and the two sides of the wire harness sealing clamp are provided with positioning blocks that slide into the positioning clamping grooves on both sides of the wire harness positioning tube for position positioning, so as to realize the combined positioning of the wire harness sealing clamp after the wire harness is combined and sealed and clamped.
[0013] Preferably, the outer end of the wire harness sealing cover is provided with a rubber gathering sleeve for gathering and positioning multiple wire harnesses, and the inner side of the rubber gathering sleeve is provided with a wire harness through hole on the corresponding positioning pressure block, so that multiple wire harnesses can be passed through the wire harness through hole to the outside of the rubber gathering sleeve for corrugated clamping and sealing.
[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This vehicle light wiring harness sealing structure, through the positioning groove inside the wiring harness positioning tube, the limiting support ring, and the two semi-circular sealing plates, corrugated wiring harness positioning groove, and corrugated sealing sleeve included in the wiring harness sealing clamp, allows the vehicle light wiring harness to be positioned in the corrugated wiring harness positioning groove in one semi-circular sealing clamp, and is clamped and sealed by the corrugated sealing sleeve. Then, the other semi-circular sealing plate is combined with it and slides into the corresponding positioning groove through the positioning block and the combined clamp, thereby clamping the wiring harness positioning inside the wiring harness positioning tube. At the same time, the wiring harness is in a corrugated structure shape inside the wiring harness sealing clamp, which gives the wiring harness better tensile resistance, making the wiring harness more secure and stable during pulling and preventing it from falling off.
[0015] The wiring harness is sealed and clamped by the locking ring, positioning block, rubber sleeve, and wiring harness through-holes in the positioning block. Multiple wiring harnesses pass through the rubber sleeve and then through the wiring harness through-holes in the movable positioning block. The wiring harness is then sealed and clamped by the wiring harness sealing clamp. After being sealed and clamped, the wiring harness is locked in the internal threaded groove of the wiring harness sealing lock cover by the threaded locking ring and fixed in the wiring harness sealing through-tube. This can press the positioning block against the wiring harness sealing clamp side in the wiring harness sealing through-tube, so that the wiring harness maintains its initial state and firmness when subjected to external force pulling and twisting after being sealed and clamped.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a sealing structure for a vehicle headlight wiring harness, comprising:
[0023] The wiring harness sealing tube 1 has a lamp housing locking ring 2 on its outside that is threadedly sealed and locked to the lamp housing, so that the connection between the wiring harness sealing tube 1 and the lamp housing is threadedly locked, thereby strengthening the firmness between the two. The wiring harness sealing tube 1 has a wiring harness positioning tube 3 inside that is positioned after the lamp wiring harness is sealed and clamped, so that the sealed and clamped wiring harness is fixed in the wiring harness positioning tube 3. One end of the wiring harness sealing tube 1 is threaded with a wiring harness sealing lock cap 8 that seals one end of the wiring harness sealing tube 1, thereby locking and sealing one end of the wiring harness sealing tube 1 after the wiring harness is sealed and clamped.
[0024] The wire harness sealing clamp 4 includes two semi-circular sealing clamps 5 that are combined as one unit to clamp and seal the wire harness. The two semi-circular sealing clamps 5 facilitate the clamping and sealing of the wire harness, eliminating the need to individually thread and seal the wire harness. The clamping side of each semi-circular sealing clamp 5 is provided with multiple corrugated wire harness positioning grooves 6, which are corrugated structures for positioning and sealing the wire harness. This allows the wire harness to maintain multiple curved structures after being sealed and clamped, giving the wire harness better tensile resistance. Furthermore, each of the corrugated wire harness positioning grooves 6 is provided with a corrugated sealing sleeve 7 for corrugated clamping and sealing of the wire harness. After the wire harness is clamped, it has a good sealing effect.
[0025] One side of the lamp housing locking ring 2 is provided with a threaded locking ring 9 with an external threaded surface for locking with the lamp housing. This allows the wiring harness sealing through-tube 1 to be locked to the lamp housing and facilitates disassembly. One end of the wiring harness sealing through-tube 1 is provided with an internal threaded locking groove 10, which locks the wiring harness sealing cover 8 to one end of the wiring harness sealing through-tube 1. Furthermore, one side of the wiring harness sealing cover 8 is provided with a locking ring 11 that locks into the internal threaded locking groove 10, thus locking the wiring harness sealing cover 8 to the wiring harness sealing through-tube 1. One end of the wire harness is positioned. The inner side of the internal threaded locking groove 10 is provided with a positioning block 12 for pressing and positioning the wire harness sealing clamp 4. The wire harness sealing clamp 4 is pressed into the wire harness positioning tube 3. The inner side of the wire harness positioning tube 3 is provided with positioning grooves 13 evenly, so that the wire harness sealing clamp 4 is positioned inside the wire harness positioning tube 3. The other end of the wire harness positioning tube 3 is provided with a limiting support ring 14 for limiting and supporting one end of the wire harness sealing clamp 4, which restricts one end of the wire harness sealing clamp 4.
[0026] The two ends of one side of the semi-circular sealing clamp 5 are provided with combination clamping plates 18 that slide into the positioning clamping groove 13 for combined clamping, so that the two semi-circular sealing clamps 5 are positioned inside the wire harness positioning tube 3 after combination. The two sides of the wire harness sealing clamp 4 are provided with positioning blocks 15 that slide into the positioning clamping groove 13 on both sides of the wire harness positioning tube 3 for position positioning, so that the wire harness sealing clamp 4 is more secure inside the wire harness positioning tube 3. The outer end of the wire harness sealing lock cover 8 is provided with a rubber gathering sleeve 16 for gathering and positioning multiple wire harnesses, so as to gather and wrap multiple wire harnesses together. The inner side of the rubber gathering sleeve 16 is provided with a wire harness through hole 17 on the positioning pressure block 12, so that multiple wire harnesses can be inserted into the wire harness sealing through tube 1, so that multiple wire harnesses can be inserted and positioned.
[0027] Specifically, in use, multiple wire harnesses are first wrapped together by the rubber gathering sleeve 16, and then each wire harness is passed through the wire harness through hole 17 provided in the positioning pressure block 12. Sufficient length is reserved for the multiple wire harnesses to facilitate sealing, clamping, and connection to the lamp board inside the vehicle headlight. The wire harnesses are then placed in a corrugated shape in the corrugated wire harness positioning groove 6 in a semi-circular sealing clamp 5. At the same time, the corrugated sealing rubber sleeve 7 is used to seal and position one side of the wire harness. Then, the other half of the semi-circular sealing clamp 5 is combined with it, and the positioning block 15 is also combined accordingly to clamp and seal the multiple wire harnesses in the wire harness sealing clamp 4. The wire harness sealing clamp 4 is then combined into the inside of the wire harness positioning tube 3. At the same time, the positioning block 15 and the combined clamping plate 18 are slid into the corresponding wire harness positioning tube. In the positioning groove 13 within component 3, the two semi-circular sealing blocks 5 are positioned and clamped inside the wiring harness positioning tube 3, keeping the wiring harness corrugated and sealed within the wiring harness sealing blocks 4. This provides the wiring harness with better tensile resistance, preventing it from breaking due to external tensile force caused by the straight seal, thus ensuring the tensile strength and stability of the wiring harness. Subsequently, the positioning pressure block 12 is pressed against one side of the wiring harness sealing blocks 4 and locked with the wiring harness sealing lock cover 8 at one end of the wiring harness sealing through-tube 1 to apply pressure and push force, giving the wiring harness a better sealing and fixing effect. After that, the wiring harness is connected to the lamp board inside the lamp housing, and the threaded locking ring 9 on the lamp housing locking ring 2 is locked onto the lamp housing to achieve the sealing and fixing of the lamp wiring harness.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
