Description

Technical Field

[0001] This utility model relates to communication line technology, specifically a high-shield industrial communication wire harness. Background Technology

[0002] To ensure safe and efficient communication during use, industrial communication harnesses typically incorporate multiple shielding elements, which are then wrapped around the outside of the wire core.

[0003] For example, the publication (announcement) number: CN221668573U, publication (announcement) date: 2024-09-06, discloses a high-shield industrial communication harness, which includes a communication line body with a metal shielding layer and various cards.

[0004] The shortcoming of existing technology is that, in actual industrial use, in order to avoid damage to the wire harness by bending, the wire harness is usually chosen to be straight as much as possible. However, when the wire harness is installed on the equipment or pulled out from the source, there will be some bending. Therefore, in this special position, the degree of bending of the wire harness is sacrificed. However, since there are many shielding layers and shielding materials in the high shielding wire harness, bending will also cause stress loss in the shielding layer, which will be damaged or even broken over time, thus affecting the shielding ability of the wire core. Utility Model Content

[0005] The purpose of this invention is to provide a highly shielded industrial communication harness to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-shield industrial communication cable harness includes a cable body with a shielding shell, wherein a triangular chamber is provided on the shielding shell, and a shielded cable is fixedly installed in the triangular chamber. It also includes an elastic strip disposed on the shielding shell, and the elastic strip is raised in a predetermined direction by default.

[0007] As a further description of the above technical solution: the shielding shell has equidistantly arranged notches for exposing the shielding wires.

[0008] As a further description of the above technical solution: the notch end is fixedly installed with oppositely arranged shell edges, and the elastic strip is disposed between the two shell edges.

[0009] As a further description of the above technical solution: a shell strip is also fixedly installed in the notch, and the elastic strip abuts against the side of the shell strip under deformation.

[0010] As a further description of the above technical solution: the included angle of the apex angle of the triangular chamber is adjustable.

[0011] As a further description of the above technical solution: the angle between the shell strip and the notch is adjustable.

[0012] As a further description of the above technical solution: the elastic strip is specifically an arc-shaped alloy elastic metal sheet.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 The present invention provides a technical solution: a high shielding industrial communication cable harness, including a cable body 1 with a shielding shell 2, a triangular chamber 21 on the shielding shell 2, and a shielding cable 3 fixedly installed in the triangular chamber 21; It also includes an elastic strip 24 disposed on the shielding shell 2, and the elastic strip 24 is raised in a predetermined direction by default.

[0022] Specifically, the shielding shell 2 is an elastic shielding material alloy metal strip (metal fiber alloy strip) with an isosceles triangular cross section. During the processing of the production line 1, the shielding shell 2 can be pre-embedded and installed along the axial direction or twisted and wound.

[0023] Furthermore, the shielding wire 3 is made of copper wire, aluminum alloy wire, and tin-plated copper wire wound together.

[0024] By arranging the shielding shell 2 circumferentially on the line body 1, the shielding shell 2 can not only provide shielding but also have deformation and bending resistance. At the same time, the shielding wire 3 is used to enhance the shielding effect. The combination of shielding shell 2 and shielding wire 3 forms a high-efficiency shielding function. When the line body 1 is bent under force, the elastic strip 24 on the shielding shell 2 bends first, and the deformation direction of the elastic strip 24 on the inner and outer sides of the bent line body 1 is away from the axis of the line body 1. This avoids the deformation of the shielding shell 2 from damaging the core components of the line body 1, ensuring the normal communication operation of the line body 1.

[0025] In another embodiment of the present invention, the shielding shell 2 has equidistant notches 22 for exposing the shielding wires 3.

[0026] Specifically, notch 22 is located at the apex of shield shell 2, and the two sides of the triangle have the same opening.

[0027] The notch 22 allows the shielding shell 2 to have bending deformation space, thereby adapting to the bending of the line 1. The shielding gap created by the notch 22 is filled by the shielding wire 3, ensuring the shielding protection of the line 1 in the circumferential direction.

[0028] In another embodiment of the present invention, a shell edge 23 is fixedly installed at the end of the notch 22 and is disposed opposite to the shell edge 23, and an elastic strip 24 is disposed between the two shell edges 23.

[0029] Specifically, the shell edge 23 is located at the bottom of the triangular waist and is connected to the elastic strip 24 to serve as an integral connection of the elastic strip 24; at the same time, the shell edge 23 and the elastic strip 24 are integrally formed on the shielding shell 2, and the elastic strip 24 is formed by extrusion molding using a mold during the production process.

[0030] By applying force to the two opposite shell edges 23 through the bending position of the notch 22, the elastic strips 24 on both sides of the triangle are more likely to deform, thereby causing the deformation bending away from the axis.

[0031] In another embodiment of the present invention, a shell strip 25 is also fixedly installed in the notch 22, and the elastic strip 24 abuts against the side of the shell strip 25 under deformation.

[0032] Specifically, the shell strip 25 is closer to the apex of the triangle than the shell edge 23, and the shell strip 25 is the same as the shell edge 23, except that the length of the shell strip 25 is greater than that of the shell edge 23 (it is also integrally formed).

[0033] The shell strip 25 restricts the two ends of the elastic strip 24, so that the elastic strip 24 will not approach the apex of the triangle during deformation. However, when the elastic strips 24 on adjacent shielding shells 2 are simultaneously subjected to outward or inward forces (the inner or outer position of the line 1 bending), the arc apex of the adjacent raised elastic strips 24 will abut against each other, and under the reaction force, the abutting position will form a bending resistance.

[0034] In another embodiment of this utility model, the included angle of the apex of the triangular chamber 21 is adjustable.

[0035] The triangular apex of the shielding shell 2 has the function of increasing or decreasing the angle, which allows the shielding shell 2 to be adjusted to the required number when it is formed on the line body 1 (the ends of adjacent shielding shells 2 after forming touch), and the shielding shell 2 has the pre-existing anti-torsion capability.

[0036] In another embodiment of this utility model, the included angle between the shell strip 25 and the notch 22 is adjustable.

[0037] When the distance between the two opposing shell edges 23 is shortened by the bent elastic strip 24, the two opposing shell strips 25 will eventually abut against each other. As the distance continues to shorten, the two shell strips 25 will also bulge away from the axis (after they are joined together, the two shell strips 25 will be triangular, and the shell strips 25 will maintain an angle of 4° with the notch 22 beforehand). On the one hand, this can increase the overall strength of the shield shell 2, and on the other hand, the reaction force due to the abutment can prevent the elastic strip 24 from bending too much and breaking.

[0038] In another embodiment of this utility model, the elastic strip 24 is specifically an arc-shaped alloy elastic metal sheet.

[0039] The alloy elastic metal sheet makes the elastic strip 24 more easily deformable at the notch 22, and the alloy elastic metal sheet also makes the shielding shell 2 have a good overall deformation capability.

[0040] In another embodiment of the present invention, a protective layer 11 is provided on the outer side of the shielding shell 2.

[0041] The protective layer 11, made of silicone rubber, fluororubber, and polyethylene, enables the line body 1 to have excellent wear resistance, pressure resistance, and high temperature resistance, making it suitable for industrial use. It can also fill the outside of the shielding shell 2 to increase the overall strength.

[0042] In another embodiment of this utility model, a hybrid layer 12 is provided on the inner side of the shielding wire 3.

[0043] The mixed layer 12, made of polyethylene, polyvinyl chloride, fluororubber, non-woven fabric or polyester tape, ensures the overall strength of the line body 1 and guarantees the safe and normal communication of the line body 1.

[0044] In another embodiment of the present invention, a wire core 13 is provided on the inner side of the mixing layer 12.

[0045] The hybrid layer 12 provides excellent protection for the wire core 13, ensuring that the wire core 13 operates in a safe environment.

[0046] Working principle: By arranging the shielding shell 2 circumferentially on the line body 1, the shielding shell 2 can not only form a shielding function, but also have the ability to resist deformation and bending. At the same time, the shielding line 3 is used to enhance the shielding effect. The combination of shielding shell 2 and shielding line 3 forms a high-efficiency shielding function. When the line body 1 is bent by force, the elastic strip 24 on the shielding shell 2 bends first. The deformation direction of the elastic strip 24 on the inner and outer sides of the bent line body 1 is away from the axis of the line body 1, so as to avoid the deformation of the shielding shell 2 from damaging the axis of the line body 1. The shell strip 25 restricts the two ends of the elastic strip 24, so that the elastic strip 24 does not approach the apex of the triangle during the deformation process. However, when the elastic strip 24 on adjacent shielding shell 2 is subjected to outward or inward force at the same time, the arc apex of the adjacent bulging elastic strip 24 will abut against each other, and the reaction force makes the abutting position form a bending resistance.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
