Description

Technical Field

[0001] This utility model relates to the field of wiring harness technology, and in particular to a headlight wiring harness. Background Technology

[0002] Automotive wiring harnesses are the medium for transmitting electrical signals between electronic devices in a car. For example, the transmission of electrical signals between the center console and various functional modules requires automotive wiring harnesses.

[0003] Traditional headlight wiring harnesses typically include: a base, metal terminals mounted on the base, and wires connecting the metal terminals. The drawback of this traditional design is that, in practical applications, the lack of protection at the connection point between the metal terminals and the wires makes the wires at this connection point prone to bending under external force. This can lead to cracking of the wires at the connection point or loosening between the wires and the metal terminals, resulting in poor electrical contact. Utility Model Content

[0004] Based on this, the present invention provides a headlight wiring harness, which adds a first support block and a second support block in a splicing and combination manner, which provides support and buffer protection for the wires located at the connection between the metal terminal and the wire, thereby reducing loosening and poor electrical contact.

[0005] A headlight wiring harness, comprising:

[0006] Base; The base has a terminal storage slot;

[0007] Metal terminals connecting to the base; the metal terminals are located in the terminal storage slot;

[0008] A wire connecting to a metal terminal; one end of the wire is connected to the metal terminal, and the other end extends beyond the terminal receiving slot; and

[0009] A support module for connecting the base; the support module includes: a first support block and a second support block that are detachably installed on the base; both the first support block and the second support block are elastic rubber blocks; both the first support block and the second support block cover the entrance of the terminal storage slot and are spliced ​​together; the first support block is provided with a first clearance groove; the second support block is provided with a second clearance groove, and the second clearance groove and the first clearance groove are spliced ​​together to form a wiring hole for wires to pass through.

[0010] During assembly of the aforementioned headlight wiring harness, the metal terminals are first connected to the wires, and then the metal terminals are placed into the terminal storage slots of the base. Next, the first support block of the support module is connected to the base, at which point the first clearance groove on the first support block partially contacts the wire. Then, the second support block is connected to the base, completing the splicing of the first and second support blocks. At this point, the first and second clearance grooves enclose a wiring hole surrounding the outer periphery of the wire. Since both the first and second support blocks are elastic rubber blocks, they protect the wire at the connection point between the metal terminals and the wire. When this connection point is subjected to external force, it provides support and cushioning, reducing the risk of wire bending and minimizing loosening and poor electrical contact. Through the above design, the addition of spliced, modular first and second support blocks provides support and cushioning protection for the wire at the connection point between the metal terminals and the wire, achieving the goal of reducing loosening and poor electrical contact.

[0011] In one embodiment, both the first support block and the second support block are snapped onto the base. The snap-fit ​​mechanism allows for detachable installation and removal of the first and second support blocks from the base, simplifying the assembly and disassembly process.

[0012] In one embodiment, the base has a threaded hole; the first support block has a through hole; the support module further includes: a pressure claw connecting the first support block and a screw passing through the pressure claw; the screw passes through the through hole and connects to the threaded hole to force the pressure claw to press the first support block and the second support block tightly onto the base. By combining the screw and the pressure claw, the first support block and the second support block are detachably mounted on the base, resulting in a simple structure and strong stability.

[0013] In one embodiment, the screw is a plastic post structure. The plastic material of the screw can provide electrical insulation protection.

[0014] In one embodiment, the screw head is provided with a flat-head tab. The flat-head tab makes it easier for operators to turn the screw without relying on auxiliary tools, reducing the difficulty of operation.

[0015] In one embodiment, the pressure claw has a limiting portion surrounding the outer sides of the first and second support blocks. The limiting portion can provide lateral positioning for the first and second support blocks, reducing the risk of displacement of the first and second support blocks.

[0016] In one embodiment, both the first support block and the second support block are silicone blocks. Silicone blocks have good electrical insulation, good elasticity, good chemical stability, good heat resistance, and are resistant to aging, resulting in a long service life.

[0044] like Figures 1 to 15 As shown, it is a headlight wiring harness 100 of one embodiment of the present utility model.

[0045] like Figures 1 to 3As shown, the headlight wiring harness 100 includes: a base 10, a metal terminal 20 connected to the base 10, a wire 30 connected to the metal terminal 20, and a support module 40 connected to the base 10. The base 10 houses the metal terminal 20. The metal terminal 20 and the wire 30 form an electrical signal transmission channel. The support module 40 protects the wire 30 at the connection point between the metal terminal 20 and the wire 30.

[0046] The following text, combined with Figures 1 to 15 As shown, the headlight wiring harness 100 described above will be further explained.

[0047] like Figure 4 and Figure 5 As shown, the base 10 is provided with terminal storage slots 11. In this embodiment, the base 10 is made of insulating plastic and has three terminal storage slots 11.

[0048] like Figure 12 As shown, the metal terminals 20 are located in the terminal storage slots 11. In this embodiment, there are three metal terminals 20, each corresponding to a pre-set terminal storage slot 11. Figure 6 As shown, in this embodiment, the metal terminal 20 includes a connecting post 21 for mating with the wire 30 and a metal sheet 22 for achieving electrical contact. There are two metal sheets 22 arranged in parallel to form a clamping space.

[0049] Combination Figure 6 and Figure 12 As shown, one end of the wire 30 is connected to the metal terminal 20, and the other end of the wire 30 extends beyond the terminal receiving groove 11. In this embodiment, one end of the wire 30 is riveted to the metal terminal 20. In this embodiment, there are three wires 30, and they are distinguished by different colored outer sheaths according to their functions.

[0050] Combination Figure 7 and Figure 14 As shown, the support module 40 includes a first support block 41 and a second support block 42, which are detachably mounted on the base 10. Both the first support block 41 and the second support block 42 are elastic rubber blocks. Both the first support block 41 and the second support block 42 cover the entrance of the terminal receiving slot 11 and are joined together. Figure 8 As shown, the first support block 41 is provided with a first clearance groove 411. Combined with... Figure 7 , Figure 9 , Figure 13 ,as well as Figure 14 As shown, the second support block 42 is provided with a second clearance groove 421, and the second clearance groove 421 and the first clearance groove 411 are spliced ​​together to form a wiring hole for the wire 30 to pass through.

[0051] Preferably, in this embodiment, both the first support block 41 and the second support block 42 are silicone blocks. Silicone blocks have good electrical insulation, good elasticity, good chemical stability, good heat resistance, and are resistant to aging, resulting in a long service life.

[0052] Brief description of working principle:

[0053] First, such as Figure 6 As shown, the metal terminal 20 is connected to the wire 30.

[0054] Then, as Figure 12 As shown, the metal terminal 20 is placed into the terminal storage slot 11 of the base 10, and the other end of the wire 30 extends beyond the terminal storage slot 11.

[0055] Next, as Figure 13 As shown, the first support block 41 of the support module 40 is connected to the base 10. At this time, the first clearance groove 411 on the first support block 41 is in partial contact with the wire 30.

[0056] Then, as Figure 14 As shown, the second support block 42 is connected to the base 10, thus completing the splicing of the first support block 41 and the second support block 42. At this time, the first support block 41 and the second support block 42 seal the metal terminal 20 in the terminal receiving groove 11, and the first clearance groove 411 and the second clearance groove 421 enclose and form a wiring hole that wraps around the outer periphery of the wire 30. Since the first support block 41 and the second support block 42 are both elastic rubber blocks, they can protect the wire 30 at the connection between the metal terminal 20 and the wire 30. When the connection is subjected to external force, it can provide support and buffer, reducing the risk of the wire 30 bending and reducing loosening and poor electrical contact.

[0057] Based on the working principle described above, the structure of this solution can be further explained.

[0058] In this solution, the first support block 41 and the second support block 42 are detachably connected to the base 10. Based on this, there are multiple ways to achieve the detachable connection.

[0059] For example, in some embodiments, both the first support block 41 and the second support block 42 are snapped onto the base 10. For instance, structures that allow for interlocking are provided on the first support block 41, the second support block 42, and the base 10. The first support block 41 and the second support block 42 are detachably mounted onto the base 10 via this snap-fit ​​method, simplifying assembly and disassembly.

[0060] For example, a detachable connection between the first support block 41 and the second support block 42 and the base 10 can be achieved using screws 44. For instance, in this embodiment, as... Figure 4As shown, the base 10 has a threaded hole 12, which is located at the axis of the base 10 and passes through the base 10. Figure 8 As shown, the first support block 41 is provided with a through hole 412. Meanwhile, as... Figures 1 to 3 As shown, the support module 40 also includes: a pressure claw 43 connecting the first support block 41 and a screw 44 passing through the pressure claw 43. (Combined) Figure 1 and Figure 15 As shown, screw 44 passes through through hole 412 and connects to threaded hole 12 to force clamping claw 43 to press the first support block 41 and the second support block 42 onto base 10. By combining screw 44 and clamping claw 43, the first support block 41 and the second support block 42 are detachably installed on base 10, resulting in a simple structure and strong stability.

[0061] Furthermore, screw 44 is preferably a plastic post structure. The plastic material of screw 44 can provide electrical insulation protection.

[0062] In addition, such as Figure 11 As shown, the head of the screw 44 may be provided with a flat-head protrusion 441. The flat-head protrusion 441 makes it easier for operators to turn the screw 44 without relying on auxiliary tools, reducing the difficulty of operation.

[0063] Combination Figure 10 and Figure 15 As shown, the pressure claw 43 may be provided with a limiting portion 431 surrounding the outside of the first support block 41 and the second support block 42. The limiting portion 431 can provide lateral positioning for the first support block 41 and the second support block 42, reducing the risk of displacement of the first support block 41 and the second support block 42.

[0064] The aforementioned headlight wiring harness 100 is equipped with a first support block 41 and a second support block 42 in a splicing and combination manner, which provides support and buffer protection for the wire 30 located at the connection between the metal terminal 20 and the wire 30, thereby reducing loosening and poor electrical contact.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
