[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the exemplified embodiments are not intended to limit the present utility model.

[0027] Embodiment 1

[0028] Referring to Figures 1-5 As shown, a cylinder-piercing wire harness module for an anti-siphon automobile of the present utility model is installed in a cylinder-piercing hole of an automobile cylinder block, and includes,

[0029] Cylinder-piercing wires 1. There are multiple cylinder-piercing wires 1, and each cylinder-piercing wire 1 includes a cable core 11, the cable core 11 is covered with a first insulating layer 12, and the first insulating layer 12 is covered with a second insulating layer 13;

[0030] A fixing plate 2. The fixing plate 2 is connected to the automobile cylinder block by screws 3 and buckled at one end of the cylinder-piercing hole A inside the automobile cylinder block, and the fixing plate 2 is provided with a plurality of through holes 21 for each cylinder-piercing wire 1 to pass through. At the same time, a sealing ring 4 surrounding the cylinder-piercing hole A is arranged between the fixing plate 2 and the automobile cylinder block.

[0031] Installation process: First, place the sealing ring 4 in the annular groove on the fixing plate 2, then make the side of the fixing plate 2 with the sealing ring 4 face the installation surface of the automobile cylinder block, and then connect the fixing plate 2 to the installation surface with screws 3. Next, pass each cylinder-piercing wire 1 through each through hole 21 on the fixing plate 2 in sequence. Finally, pour sealing glue 5 into the cylinder-piercing hole for sealing.

[0032] It can be imagined that the through holes 21 can be prefabricated on the fixing plate 2, or the fixing plate 2 can be installed on the cover plate of the automobile cylinder block first and then drilled according to specific requirements; and threaded holes can be designed on the cover plate of the automobile cylinder block to facilitate the connection of the fixing plate 2, further improving the installation efficiency and the unity of the installation position.

[0033] A cylinder-piercing wire harness module for an anti-siphon automobile of the present utility model simplifies the structure and method of threading cables into the cylinder-piercing holes of an automobile cylinder block. By setting the fixing plate 2 to cooperate with the cables to replace the original structure and method of preparing wire harnesses by mold injection, it not only reduces the design and use costs, but also can prepare or replace fixing plates that can thread different numbers of cables according to actual needs, improving the versatility of the entire wire harness module and further reducing the use costs.

[0034] Referring to Figure 1 and Figure 2 As shown, further, it also includes sealing glue 5. A receiving cavity is formed between the fixing plate 2 and the cylinder-piercing hole, and the sealing glue 5 is filled in the receiving cavity.

[0035] Further, the cable core 11 includes a plurality of tinned conductors 111. The plurality of tinned conductors 111 are twisted together and coated with a silicon-based sealant 112, and the silicon-based sealant 112 is also filled between the tinned conductors 111. Specifically, the silicon-based sealant 112 is filled between the tinned conductors 111 in a heated and molten manner during the stranding process of the tinned conductors 111, and a thin layer of silicon-based sealant 112 is formed outside the stranded cable core through a die. Specifically, 19 tinned conductors 111 with a diameter of 0.26 mm can be stranded to form the cable core 11, and the diameter of the cable core 11 after stranding and sealing is not greater than 1.26 mm.

[0036] Further, the first insulating layer 12 is made of cross-linked polyolefin (XLPO) material, and the second insulating layer 13 is made of cross-linked polyvinylidene fluoride (XL-PVDF) material. Specifically, the outer diameter of the first insulating layer 12 is 1.6 ± 0.05 mm, and the outer diameter of the second insulating layer 13 is 2.0 ± 0.10 mm. Specifically, the original in-tank cable usually uses a single layer of ethylene-tetrafluoroethylene copolymer (XL-ETFE) as the insulating layer, with a high usage cost; while this in-tank cable 1 is provided with two insulating layers outside the cable core 11, and the two insulating layers are made of materials with different properties and functions and cooperate with each other complementarily, so that under the premise of meeting the original performance requirements and functions, a lower-cost material can be selected, thereby reducing the manufacturing cost of the entire cable. Specifically, the first insulating layer 12 can improve the electrical performance of the cable and has a low cost; the second insulating layer 13 is an XL-PVDF material formed by granulating after adding a photosensitive cross-linking agent, a PVDF affinity agent, and other admixtures to the product base material. It has better affinity with a variety of sealants 5, which is beneficial to the final sealing effect, and this insulating material has high temperature resistance and excellent mechanical properties. The product after radiation cross-linking has anti-vibration, abrasion resistance, and excellent flame retardancy, while reducing the manufacturing cost of the product.

[0037] Further, the surface of the second insulating layer 13 is subjected to a matte treatment. It can be imagined that by subjecting the surface of the second insulating layer 13 to a matte treatment, it is beneficial to the tight combination between the sealant 5 and the in-tank cable 1, can improve the final sealing effect, and avoid the occurrence of liquid leakage.

[0038] Refer to Figure 3 and Figure 5 As shown, further, the through hole 21 is a round hole, and the inner diameter of the through hole 21 matches the diameter of the in-tank cable 1. Specifically, the diameter of the through hole 21 should not be too large and should be slightly larger than the outer diameter of the in-tank cable 1 to facilitate the insertion of the in-tank cable 1 while ensuring the sealing effect when the sealant 5 is sealed.

[0039] Further, the fixing plate 2 is a rectangular plate. A mounting hole 22 is respectively provided at a position near each of the four corners of the fixing plate 2. The fixing plate 2 is connected to the inner wall of the automotive cylinder block by screws 3 at the mounting holes 22. Specifically, the fixing plate 2 is not limited to a rectangular plate, and the shape of the fixing plate 2 can be set according to the specific shape of the mounting position of the automotive cylinder block to ensure that the fixing plate 2 can be stably attached to the mounting surface and guarantee the final sealing effect.

[0040] Further, an annular groove 23 surrounding the cylinder-piercing hole is provided on one surface of the fixing plate 2. The inner diameter of the annular groove 23 is larger than the diameter of the cylinder-piercing hole. The sealing ring 4 is arranged in the annular groove 23. More preferably, an annular groove 23 can also be provided on the mounting surface of the automotive cylinder block, so that the annular grooves 23 on the fixing plate 2 and the mounting surface of the automotive cylinder block form a receiving groove for installing the sealing ring 4, which is convenient for installing the sealing ring 4.

[0041] Further, the through holes 21 are arranged in a matrix on the fixing plate 2. Specifically, the through holes 21 arranged in a circular array or a matrix can be provided on the fixing plate 2 according to actual requirements.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
