[0002] As car lights are installed in a small space, the wires will be in a high temperature environment, which will cause the wires to age and produce volatile gases. On the other hand, fog will be produced during operation, affecting the effect and service life of the lights. The high temperature resistant, ultra-thin wall, low volatility wires specially designed for car lights can reduce the volatility of the wires under high temperature conditions.

[0003] Now we search for a Chinese patent for a process structure that solves the air tightness of wires for automobile lamps, with publication number CN214745497U, which includes a bottom plate and a box body, and the box body is fixedly connected to the bottom plate, which solves the technical problems of poor air tightness of wires for automobile lamps and serious fogging of automobile lamps, including a lamp line main body, characterized in that the lamp line main body includes an insulating protective layer, the interior of the insulating protective layer is filled with a tin layer, and the interior of the tin layer is wrapped with a plurality of copper wires, and the outer surface of the end of the insulating protective layer is sleeved with a heat shrink tube containing glue, and a sealed cavity is formed between the heat shrink tube containing glue and the insulating protective layer and the tin layer. The utility model arranges a heat shrink tube containing glue at the wire joint, and the heat shrink tube containing glue is composed of an outer polyolefin alloy layer and an inner hot melt adhesive layer. The outer polyolefin alloy layer can effectively enhance the corrosion resistance and wear resistance of the wire, and the inner hot melt adhesive layer can effectively enhance the waterproof sealing and mechanical strain buffering performance of the wire.

However, the sleeve connection method causes the seal to move during use, resulting in poor sealing. The movement of the seal will increase the probability of damage, reducing the service life of the seal. Utility Model Content

[0038] Embodiment 1

[0039] See also Figure 1-4 As shown, this embodiment is a high temperature resistant, extremely thin-walled, low volatility electric wire specially used for automobile lamps, comprising:

[0040] The main body component includes an outer sheath 10, a connector terminal 14 clamped on the outer sheath 10, a tin layer 11 filled in the outer sheath 10, an insulating layer 12 filled in the tin layer 11, and a conductor 13 filled in the insulating layer 12;

[0041] There are seven groups of insulating layers 12 and conductors 13, one in the middle, and the remaining six groups are circularly hinged on the outer ring of the middle conductor 13;

[0042] The conductor 13 is a single-core structure, and is made of soft round copper wire or tinned soft round copper wire with a purity of more than 99.99%, with a cross-section of 0.3f-2.0fmm2. The single wire of the conductor 13 is twisted in layers, and the twisting direction is left-handed, so as to ensure that the conductor 13 has a stable structure when bent. An insulating layer 12 is uniformly extruded from the conductor 13 by extrusion, and the insulation is made of a new polyethylene material (temperature range: (-40~+125)℃), so that the processing temperature can be reduced during the extrusion process, so that the original high temperature production The small molecules generated by degradation maintain their original properties at a lower temperature, thereby reducing the atomization result of this material. The thinnest point of the insulation is not less than 80% of the nominal thickness of the insulation. To ensure that the outer diameter is not greater than the use requirements, the concentricity must reach more than 85%. The outer sheath 10 is usually made of wear-resistant, grease-resistant and chemical-resistant materials, such as polyvinyl chloride or polyurethane. The outer sheath 10 can protect the wires from damage by the external environment and improve the durability of the wires. The tin layer 11 plays a sealing role and the connector terminal 14 plays a connecting role.

[0043] The sealing assembly includes a first card slot 25 connected to the connector terminal 14 by screws, a card block 24 carded in the first card slot 25, a spring column 23 welded to the card block 24, a first sealing collar 20 connected to the spring column 23 by screws, a sealing plate 21 connected to the first sealing collar 20 by one-time injection molding, and a first sealing ring 22 connected to the sealing plate 21 by countersunk screws;

[0044] There are two groups of first slots 25, blocks 24 and spring posts 23, one to one corresponding to each other;

[0045] The first sealing sleeve ring 20 and the sealing plate 21 play a sealing role, the first sealing ring 22 can enhance the sealing performance, and the clamping block 24, the first clamping groove 25 and the spring column 23 play a connecting role.

[0046] Working principle:

[0047] The first sealing ring 20 is put on the outer sheath 10, the spring column 23 is fixed to the inner wall of the first sealing ring 20 by screws, and the first slot 25 is fixed to the connector terminal 14 by screws;

[0048] Pull the spring column 23 to engage the clamping block 24 in the first clamping groove 25, and release your hand until the spring column 23 contracts;

[0049] The connector terminal 14 is inserted into the vehicle lamp assembly. At this time, under the action of the spring column 23, the sealing plate 21 and the first sealing ring 22 are attached to the vehicle lamp assembly.

[0050] This step can ensure the stability of the connection between the sealing component and the wire.

[0051] Embodiment 2

[0052] See also Figure 5 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0053] The adjustment component includes a third slot 32 connected to the inner side of the first sealing collar 20 by injection molding, a second slot 31 movably connected in the third slot 32, a second sealing collar 30 connected to the second slot 31 by injection molding, a second sealing ring 33 connected in the second slot 31 by countersunk screws, a fourth slot 34 connected to the second sealing collar 30 by injection molding, a fifth slot 36 movably connected in the fourth slot 34, a third sealing ring 37 connected in the fifth slot 36 by countersunk screws, a third sealing collar 35 connected to the fifth slot 36 by injection molding, and a fourth sealing ring 38 connected in the third sealing collar 35 by countersunk screws;

[0054] The second sealing ring 30 and the third sealing ring 35 play a sealing role, the second slot 31, the third slot 32, the fourth slot 34 and the fifth slot 36 play a connecting role, and the second sealing ring 33, the third sealing ring 37 and the fourth sealing ring 38 can enhance the sealing performance.

[0055] Working principle:

[0056] Connect the fourth sealing ring 38 to the third sealing ring 35 with countersunk screws, connect the third sealing ring 37 to the fifth clamping groove 36 with countersunk screws, and connect the second sealing ring 33 to the second clamping groove 31 with countersunk screws;

[0057] The fourth groove 34 on the second sealing ring 30 is engaged with the fifth groove 36 on the third sealing ring 35, and the third groove 32 on the first sealing ring 20 is engaged with the second groove 31 on the second sealing ring 30;

[0058] Put the first sealing ring 20, the second sealing ring 30 and the third sealing ring 35 onto the outer sheath 10;

[0059] The first sealing ring 20 is connected to the connector terminal 14 so that the first sealing ring 20, the second sealing ring 30 and the third sealing ring 35 are in a fully stretched state. Due to the elastic sealing effect of the fourth sealing ring 38, the fourth sealing ring 38 fits tightly on the outer sheath 10.

[0060] This step improves the applicability of the sealing component.
