[0002] Currently, a large number of automotive wiring harnesses are needed to connect various electrical components in automobiles. In order to facilitate automobile production and assembly, the automotive wiring harnesses are usually inserted into various types of casings. Through the setting of various casings, the automotive wiring harnesses are protected while improving the aesthetics of the wiring in the car cabin.
[0003] In existing automotive bushing products, the bushing is generally required to have excellent impact resistance and flame retardancy to protect the automotive wiring harness inside the bushing.
[0004] Among various types of automobile sleeves, reverse knitted sleeves are often used as automobile sleeves, but the existing reverse knitted sleeves have poor support performance. Utility Model Content

[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] A reverse knitted sleeve is made of a weft-knitted fabric layer or a ribbed fabric layer, in which reinforcing wires are passed between a number of overlapping Ω-shaped loops in the weft-knitted fabric layer or the ribbed fabric layer; between the adjacent and overlapping Ω-shaped loops, the reinforcing wires are sequentially passed through each of the Ω-shaped loops in an up-and-down staggered manner.
[0008] Furthermore, the reinforcing wire is inserted between the Ω-shaped rings having the same orientation.
[0009] Furthermore, between adjacent Ω-shaped rings having the reinforcing wires interlaced in the same weft direction, each reinforcing wire passes through each Ω-shaped ring in sequence.
[0010] Furthermore, each of the Ω-shaped rings is interspersed with the reinforcing wire.
[0011] Furthermore, the Ω-shaped ring is made of PET multifilament.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0027] In order to improve the support of the reverse knitted sleeve for automobiles and achieve the lightweight of the reverse knitted sleeve, the utility model discloses a reverse knitted sleeve made of a weft plain knitted fabric layer or a ribbed fabric layer. Figures 1 to 3 As shown, in the weft direction of the weft knitted fabric layer or the ribbed fabric layer, the silk thread is bent into an Ω shape to form an Ω-shaped loop 1. And in the same weft direction, adjacent Ω-shaped loops 1 are reversed in sequence to make the silk thread into a snake shape. At the same time, in different weft directions, a number of Ω-shaped loops 1 arranged in a snake shape are provided in each weft direction. In addition, in the same warp direction, a number of Ω-shaped loops 1 are all arranged in the same direction, and adjacent Ω-shaped loops 1 overlap with each other. The improvement of the reverse knitted sleeve of the present invention is that, in the same warp direction, a number of overlapping Ω-shaped loops 1 are passed through with reinforcing wires 2. Specifically, between adjacent and overlapping Ω-shaped loops 1, the reinforcing wires 2 are staggered up and down and pass through each Ω-shaped loop 1. As shown Figure 1 As shown, the three Ω-shaped rings 1 that overlap in the same meridian direction and are arranged in the same direction are defined as the first Ω-shaped ring 1a, the second Ω-shaped ring 1b and the third Ω-shaped ring 1c. Figure 1 The direction of the plane facing inward is downward, and the definition Figure 1 The direction of the plane facing outward is upward. Figure 1Taking the first Ω-shaped loop 1a, the second Ω-shaped loop 1b, and the third Ω-shaped loop 1c in the figure as an example, the reinforcing wire 2 first passes through the bottom of the first Ω-shaped loop 1a, then passes through the top of the second Ω-shaped loop 1b, and finally passes through the bottom of the third Ω-shaped loop 1c. The present invention enhances the support of the reverse knitted sleeve by staggering the reinforcing wire 2 up and down between adjacent and overlapping Ω-shaped loops 1. That is, the reinforcing wire 2 is arranged along the length of the reverse knitted sleeve. While the reverse knitted sleeve has a certain degree of flexibility, it is not easy to bend excessively, which would make it difficult for the automotive wiring harness to pass through the reverse knitted sleeve. In addition, the provision of the reinforcing wire 2 can reduce the weight of the reverse knitted sleeve of the present invention, achieving a lightweight effect.
[0028] The reverse knitted sleeve of the present invention has various embodiments for various technical features, such as the arrangement of the reinforcing wires 2 in different warp directions, the specific structure of the Ω-shaped ring 1, and the specific structure of the reinforcing wires 2. Below, we will describe in detail one embodiment of each of these various technical features, such as the arrangement of the reinforcing wires 2 in different warp directions. This embodiment will be referred to as the present embodiment. Other embodiments of these various features are referred to as other embodiments, which are briefly described below.
[0029] In this embodiment, if Figure 1 As shown, the reinforcing wire 2 is only inserted between the Ω-shaped rings 1 with the same orientation. That is, among the Ω-shaped rings 1 arranged in sequence in the same latitude direction and with the same orientation, the reinforcing wire 2 is inserted into the Ω-shaped rings 1 in odd or even rows. By limiting the reinforcing wire 2 to be inserted into the Ω-shaped rings 1 in odd or even rows, the reverse knitted sleeve of the present invention has enhanced support while still maintaining a certain degree of flexibility. In other embodiments, such as Figure 4 As shown, each Ω-shaped loop 1 can be interspersed with a reinforcing wire 2. That is, each Ω-shaped loop 1 arranged in an inverted manner can be interspersed with a reinforcing wire 2, and each reinforcing wire 2 can be parallel to each other. Each reinforcing wire 2 sequentially passes through each overlapping Ω-shaped loop 1 in a different warp direction. In this embodiment, the support of the reverse knitted sleeve is further enhanced, but the flexibility of the reverse knitted sleeve is reduced, and the reverse knitted sleeve is not easy to bend.
[0030] In this embodiment, if Figure 1 As shown, between adjacent Ω-shaped rings 1 with interlaced reinforcing wires 2 in the same weft direction, each reinforcing wire 2 sequentially passes through each Ω-shaped ring 1 in the same direction. Specifically, the same definition is given. Figure 1 The direction of the plane facing inward is downward, and the definition Figure 1The plane faces upward, and three adjacent omega loops 1 arranged in the same latitude and in the same direction are defined as the fourth omega loop 1d, the fifth omega loop 1e, and the first omega loop 1a. Specifically, the fourth omega loop 1d, the fifth omega loop 1e, and the first omega loop 1a are arranged in the same latitude and in the same direction. The reinforcing wire 2 passing through the fourth omega loop 1d passes from below, the reinforcing wire 2 passing through the fifth omega loop 1e passes from above, and the reinforcing wire 2 passing through the first omega loop 1a passes from below. By sequentially passing reinforcing wires 2 up and down through different omega loops 1 in the same latitude, the present invention achieves improved flatness in the resulting reverse knitted sleeve. In other embodiments, between adjacent omega loops 1 with interlaced reinforcing wires 2 in the same latitude, each reinforcing wire 2 passes through each omega loop 1 using the same method.
[0031] In this embodiment, the Ω-shaped ring 1 is made of PET multifilament, meaning that the plain knit fabric layer or rib fabric layer is woven with PET multifilament. PET multifilament is polyester multifilament, which is light-resistant, wear-resistant, wrinkle-resistant, and soft. This gives the resulting reverse-knitted sleeve similar advantages. In other embodiments, the Ω-shaped ring 1 can also be made of PPS multifilament, PEEK multifilament, PA multifilament, PE multifilament, or any other material.
[0032] In this embodiment, the dtex value range of the PET multifilament yarn is greater than or equal to 1670 and less than or equal to 2200, indicating that the PET multifilament yarn is relatively lightweight. By limiting the dtex value range of the PET multifilament yarn, the present invention effectively achieves lightweighting of the reverse knitted sleeve. In other embodiments, when each omega loop 1 is interspersed with a reinforcing yarn 2, the dtex value range of the PET multifilament yarn used to braid the omega loop 1 can be less than 1670.
[0033] In this embodiment, the PET multifilament is produced by twisting a plurality of polyester monofilaments. The diameter of the polyester monofilaments ranges from 0.18 mm to 0.38 mm. By using relatively thin polyester monofilaments, the present invention facilitates twisting to produce the PET multifilament. In other embodiments, when reinforcing yarns 2 are inserted through each Ω-shaped ring 1, the diameter of the polyester monofilaments used to twist the PET multifilament can also be less than 0.18 mm.
[0034] In this embodiment, the reinforcing yarn 2 is a polyester monofilament or a nylon monofilament. Polyester monofilament has the advantages of high strength, good elasticity, good wear resistance, and good light resistance. Nylon monofilament has the advantages of being lightweight, wear-resistant, and tear-resistant. By limiting the reinforcing yarn 2 to polyester monofilament or nylon monofilament, the woven reverse knitted sleeve has advantages such as good wear resistance. In other embodiments, the reinforcing yarn 2 can also be a PPS monofilament or a PVC monofilament.
[0035] In this embodiment, when the reinforcing yarn 2 is a polyester monofilament, the diameter of the polyester monofilament is greater than or equal to 0.18 mm and less than or equal to 0.38 mm. By using a relatively fine polyester monofilament, the present invention facilitates the production of a lightweight reverse-knitted sleeve. In other embodiments, when each Ω-shaped ring 1 is interspersed with a reinforcing yarn 2, the diameter of the polyester monofilament used as the reinforcing yarn 2 can also be less than 0.18 mm.
[0036] In this embodiment, when the reinforcing wire 2 is a nylon monofilament, the diameter of the nylon monofilament is greater than or equal to 0.25 mm and less than or equal to 0.38 mm. By using a relatively thin nylon monofilament, the present invention facilitates the production of a lightweight reverse-knitted sleeve. In other embodiments, when each Ω-shaped ring 1 is interspersed with a reinforcing wire 2, the diameter of the nylon monofilament used as the reinforcing wire 2 can also be less than 0.25 mm.
[0037] In summary, the present invention enhances the support of the reverse knitted sleeve and achieves lightweighting by sequentially interlacing the reinforcing yarns 2 between adjacent and overlapping Ω-shaped loops 1. Furthermore, by restricting the reinforcing yarns 2 to be inserted between odd-numbered or even-numbered rows of Ω-shaped loops 1, the reverse knitted sleeve of the present invention achieves enhanced support while maintaining a certain degree of flexibility. Furthermore, by arranging each reinforcing yarn 2 to sequentially pass through different Ω-shaped loops 1 in the same weft direction, the resulting reverse knitted sleeve exhibits improved flatness. Furthermore, by restricting the Ω-shaped loops 1 to be made of PET multifilament, the resulting reverse knitted sleeve exhibits advantages such as light resistance, wear resistance, wrinkle resistance, and softness. Furthermore, by restricting the detex value range of the PET multifilament, the reverse knitted sleeve is effectively lightweight. Furthermore, by using finer polyester monofilament, twisting to form the PET multifilament is facilitated. Furthermore, by restricting the reinforcing yarns 2 to be polyester monofilament or nylon monofilament, the resulting reverse knitted sleeve exhibits advantages such as excellent wear resistance. The utility model adopts relatively thin polyester monofilament or nylon monofilament, so that the reverse knitted sleeve knitted out has the advantage of being lightweight.
[0038] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
