Description

Technical Field

[0001] This application relates to the technical field of intermediate components for distributing electrical energy to two or more parallel circuits, and more specifically to a wiring harness for automotive headlights. Background Technology

[0002] In the connection structure between the conductive wire harness and the plug in the wiring harness assembly structure, as described in the utility model document with announcement number CN218887740U, multiple connection holes are opened through the plug, and a conductive sleeve is inserted into the connection holes. The wire harness core extends into the conductive sleeve, and a conductive clamp is fixedly provided on the inner side of the conductive sleeve for clamping the wire harness core. During vehicle operation, vibration will occur, and the snap-fit ​​structure between the wire harness core and the conductive clamp is prone to resonance effect, which will lead to the failure of the connection of the wire harness head. Moreover, the conductive clamp only occupies a small part of the surface area of ​​the conductive sleeve, which increases the contact resistance and affects the performance of the wire harness. Summary of the Invention

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a wiring harness for automotive headlights, and the technical solution adopted includes:

[0004] A wiring harness for automotive headlights includes a main plug with multiple connection holes and multiple conductive sleeves. Each conductive sleeve includes a vertical connecting portion and multiple elastic pieces. The multiple elastic pieces are spaced apart and connected to the vertical connecting portion, with the side of each elastic piece closest to the opening of the connection hole inclined outward. The conductive sleeve is inserted into the connection hole, and the elastic pieces deform under the action of the outer wall of the connection hole and press against the outer wall of the wiring harness core.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the elastic sheet is provided with anti-slip texture.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the middle section of the connecting hole is provided with a tapered part, and the tapered part gradually increases in size from one end near the opening of the connecting hole to the other end.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a stress relief groove is provided on the inner side of the elastic sheet near the vertical connecting part.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the wire harness includes a wire harness core and an insulating layer disposed outside the wire harness core, and the opening of the connection hole and the wire harness are filled with sealant.

[0009] The beneficial effects of this utility model are as follows: When the conductive sleeve and the wire harness are simultaneously inserted into the connecting hole, the elastic sheet deforms towards the inside of the connecting hole under the action of the hole wall and presses against the wire harness core. This utilizes multiple elastic sheets to lock the wire harness, optimizing the mechanical locking capability of the conductive sleeve on the wire harness, improving connection reliability, and avoiding connection failure of the wire harness due to resonance caused by vehicle movement. Furthermore, the multiple elastic sheets, under the action of the connecting hole, enclose and form a sidewall that matches the hole wall, increasing the contact area with the wire core and improving electrical performance.

[0020] Reference Figure 1-5 This application proposes an embodiment of a wiring harness for automotive headlights, which includes a main plug 1. The plug has multiple connection holes 2 and multiple conductive sleeves 3. Each conductive sleeve 3 includes a vertical connection portion 31 and multiple elastic pieces 32. The multiple elastic pieces 32 are spaced around the vertical connection portion 31 and connected to it. The side of each elastic piece 32 closest to the opening of the connection hole 2 is inclined outward. The conductive sleeve 3 is inserted into the connection hole 2. The elastic pieces 32 are deformed under the action of the outer wall of the connection hole 2 and abut against the outer wall of the wiring harness core 41.

[0021] The automotive headlight wiring harness described in this application includes a main plug 1 and multiple wiring harnesses 4. The other ends of the multiple wiring harnesses can be connected to a power supply plug, a control plug, and a signal plug, respectively. The main plug 1 is provided with multiple connection holes 2. The wiring harness 4 includes a wiring harness core 41 and an insulating layer 42 disposed outside the wiring harness core 41. The outer diameter of the vertical connecting part 31 matches the outer diameter of the connection hole 2. When the conductive sleeve 3 and the wiring harness are simultaneously inserted into the connection hole 2, the elastic piece 32 deforms towards the inside of the connection hole 2 under the action of the hole wall of the connection hole 2 and presses against the wiring harness core 41. Thus, the multiple elastic pieces 32 are used to lock the wiring harness, which optimizes the mechanical locking ability of the conductive sleeve 3 on the wiring harness, improves the connection reliability, and avoids the connection failure of the wiring harness caused by resonance effect due to vehicle driving. Moreover, the multiple elastic pieces 32 are surrounded by the connection hole 2 to form a sidewall that matches the hole wall of the connection hole 2. The elastic pieces 32 increase the contact area with the wire core and improve electrical performance.

[0022] Preferably, the inner side of the elastic sheet 32 ​​is provided with an anti-slip texture 5 that contacts the conductive core. The anti-slip texture 5 can be designed as a mesh structure to increase the friction between the elastic sheet 32 ​​and the conductive core, which is beneficial to further improve the mechanical locking ability of the conductive sleeve 3 for the wire harness.

[0023] In this embodiment, a tapered section can be further designed inside the connecting hole 2. The middle section of the connecting hole 2 has a tapered portion, which gradually increases in size from one end near the opening of the connecting hole 2 to the other end. The inner wall of the connecting hole 2 has a tapered shape opposite to that of the conductive sleeve 3, so that the elastic sheet 32 ​​can deform as much as possible under the action of the inner wall of the connecting hole 2, ensuring the mechanical locking ability of the conductive sleeve 3 on the wire harness; and the fact that the inner wall of the connecting hole 2 has a tapered shape opposite to that of the conductive sleeve 3 can also prevent the conductive sleeve 3 from displacing under vehicle vibration.

[0024] Preferably, the elastic sheet 32 ​​is provided with a stress relief groove 6 on the inner side of one end near the vertical connecting portion 31. The stress relief groove 6 can reduce or release the stress generated when the elastic sheet 32 ​​deforms on the inner wall of the connecting hole 2, thereby preventing damage to the elastic sheet 32.

[0025] The wire harness includes a wire harness core 41 and an insulating layer 42 disposed outside the wire harness core 41. Based on the above structure, the wire harness is inserted between the tapered portion and the opening of the connecting hole 2, and the connecting hole is filled with sealant 7 between the wire harness and its wall. The connecting hole 2 is sealed with sealant 7.

[0026] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
