Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, and in particular relates to a bending-resistant silicone rubber cable. Background Art

[0002] Silicone rubber cables are suitable for mobile or fixed installation of electrical instrument connections or signal transmission with an AC rated voltage of 450 / 750V or below. Silicone rubber cables have good thermal stability and can maintain good electrical properties and flexibility in high and low temperatures and corrosive environments. They are suitable for use in industries such as metallurgy, electric power, petrochemicals, electronics, and automobile manufacturing that have special requirements such as mobile and temperature resistance.

[0003] For example, a bending-resistant silicone rubber high-temperature cable with publication number CN219267349U includes an inner sheath, a filler is fixed inside the inner sheath, a core is provided inside the inner sheath, an auxiliary component is provided on the core, an elastic part is fixed on the outside of the inner sheath, an outer sheath is fixed on the outside of the elastic part, and a protective component is provided on the outer sheath. The bending-resistant silicone rubber high-temperature cable is provided with a protective component and an auxiliary component. The mutual cooperation between the various structures of the protective component and the auxiliary component can greatly improve the bending resistance of the cable. The cooperation of the reinforcement layer, the anti-bending layer and the anti-stretching layer can avoid the cable from being damaged during use. The cooperation of the flame retardant layer and the protective layer can protect the cable. It can also avoid the cable from being affected by external heat during use. The heat insulation layer is used to block heat. At the same time, the insulating layer and the shielding layer can improve the use effect of the cable.

[0004] The inventor believes that in the prior art, when improving the bending resistance of silicone rubber cables, an anti-bending layer, such as a steel wire braided layer, is often added inside the outer sheath;

[0005] However, this method only increases the bending difficulty of the cable, making it less likely to bend and thus achieving bending resistance. When it is excessively bent, the outer sheath on its surface is still easily damaged, and the bending durability is poor. Therefore, in actual use, this type of cable is not suitable for circuit wiring with high flexibility.

[0006] In view of this, the utility model provides a bending-resistant silicone rubber cable to meet market demand. Utility Model Content

[0007] The purpose of the utility model is to provide a bending-resistant silicone rubber cable, aiming to solve the problem that the cable in the prior art has poor bending resistance and the outer sheath is prone to bending and damage when bent during long-term use.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a bending-resistant silicone rubber cable, comprising a conductor, the outside of which is wrapped with an insulating sleeve, the outside of which is wrapped with a shielding layer, the outside of which is wrapped with a cabling tape, the outside of which is further wrapped with a bending-resistant outer sheath, and the end cross-section of the outer sheath is elliptical and flat.

[0009] In order to improve the electrical conductivity of the cable, as a preferred bending-resistant silicone rubber cable of the present invention, the conductor is made of copper or aluminum.

[0010] As a preferred bending-resistant silicone rubber cable of the present invention, the insulating sheath and the outer sheath are both made of silicone rubber.

[0011] In order to improve the safety of cable use, as a preferred embodiment of the bending-resistant silicone rubber cable of the present invention, the shielding layer is woven with copper wire.

[0012] In order to improve the bending resistance of the cable, as a preferred bending-resistant silicone rubber cable of the present invention, the outer sheath includes: an outer sheath body and a bending deformation groove, the bending deformation groove is an inverted triangle, and the bending deformation groove is symmetrically opened on the flat surface of the outer sheath body.

[0013] In order to improve the bending resistance of the cable, as a preferred bending-resistant silicone rubber cable of the present invention, the outer sheath is a telescopic sleeve, and the cross-section of the telescopic sleeve is corrugated.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model has an outer sheath with bending resistance, so that when the cable is bent, the bending deformation groove or the corrugated expansion sleeve can make the cable easy to bend, and the bending degree is large, and it is not easy to cause damage to the outer surface, so the bending resistance is very good;

[0016] Secondly, due to the increase in the surface area of ​​the outer sheath, the heat dissipation effect of the cable is improved, which effectively reduces the high temperature of the cable and increases the service life and conductive efficiency of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 4 The utility model provides the following technical solutions: a bending-resistant silicone rubber cable, comprising a conductor 1, an insulating sleeve 2 wrapped around the outside of the conductor 1, a shielding layer 3 wrapped around the outside of the insulating sleeve 2, a cabling tape 4 wrapped around the outside of the shielding layer 3, the cabling tape 4 can be selected from polyester film tape, ultra-high molecular weight polyethylene tape, glass fiber tape, etc. according to the actual use requirements of the cable, the cabling tape 4 is further wrapped with a bending-resistant outer sheath 5, and the end cross-section of the outer sheath 5 is elliptical and flat.

[0025] Preferably, the conductor 1 is made of copper or aluminum.

[0026] In specific use, copper or aluminum has good electrical conductivity and is currently the commonly used conductor 1 material.

[0027] Preferably, the insulating sleeve 2 and the outer sheath 5 are both made of silicone rubber.

[0028] In specific use, silicone rubber has good high temperature resistance, cold resistance, electrical insulation and air permeability. Therefore, cables made of silicone rubber can be used in extreme environments.

[0029] Preferably, the shielding layer 3 is braided with copper wires.

[0030] During specific use, the shielding layer 3 of the cable is used as electromagnetic compatibility protection. It can prevent interference signals from inside the cable from reaching the outside and interfering with other cables or even electrical equipment. In addition, the shielding layer 3 ensures that external interference will not reach the inside of the cable, reducing the radiation signal of the cable, reducing the impact of electrical hazards, and limiting the impact of external electromagnetic interference on the shielded cable. Secondly, if the cable is damaged, the leaked current can flow into the grounding grid along the shielding layer 3, playing a role in safety protection.

[0031] Example 1:

[0032] Preferably, the outer sheath 5 includes an outer sheath body 501 and a bending deformation groove 502 . The bending deformation groove 502 is in an inverted triangle shape and is symmetrically arranged on the flat surface of the outer sheath body 501 .

[0033] When used specifically, Figure 1 - Figure 2 As shown, since the outer sheath 5 is designed to be flat and oval, the cable is not easily bent in the transverse direction, but is easily bent in the longitudinal direction. Due to the provision of the bending deformation grooves 502, bending spaces are formed between the bending deformation grooves 502, so that the cable can be bent well without causing surface damage, and has good bending resistance and safety.

[0034] Secondly, due to the provision of the bending deformation groove 502, the contact area between the surface of the outer sheath body 501 and the external environment is increased, thereby further improving the heat dissipation effect of the cable and increasing the service life of the cable, thus achieving two goals at one stroke.

[0035] Example 2:

[0036] Preferably, the outer sheath 5 is a telescopic sleeve 6 , and the cross section of the telescopic sleeve 6 is corrugated.

[0037] When used specifically, Figure 3 - Figure 4 As shown, the gap between the telescopic sleeve 6 and the cabling tape 4 can be filled with thermal grease to improve the heat dissipation effect; in addition, the corrugated telescopic sleeve 6 has good elasticity and deformation ability, thereby improving the bending resistance of the cable and preventing surface damage during bending.

[0038] Working Principle: This bending-resistant silicone rubber cable has a corrugated and deformable outer sheath, making the entire cable easy to bend while preventing surface damage or material loss due to bending. This effectively improves the cable's bending resistance. In addition, the corrugated design further increases the surface area, improves heat dissipation, and extends service life.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
