Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a novel bend-resistant polyester halogen-free environmentally friendly explosion-proof shielded control cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and many more.

[0003] In demanding industrial environments, particularly those involving explosion risks, humidity, oil contamination, chemical corrosion, frequent movement or bending, and extremely stringent environmental requirements such as petrochemicals, mining equipment, and food processing, the demand for reliable, durable, and secure signal connections is extremely high. Therefore, existing solutions do not meet these needs. To address this, we propose a novel bend-resistant polyester halogen-free, environmentally friendly, explosion-proof shielded control cable. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of bend-resistant polyester halogen-free environmentally friendly explosion-proof shielded control cable to solve the problem mentioned in the background art that existing cables for reliable, durable and safe signal connections are required in demanding industrial environments, especially in places with explosion risks, humidity, oil stains, chemical corrosion, frequent movement or bending, and extremely high environmental protection requirements, such as petrochemical, mining equipment, and food processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel bend-resistant polyester halogen-free environmentally friendly explosion-proof shielded control cable, comprising a cable mounting layer, a cable protection composite layer mounted on the outer side of the cable mounting layer, the cable protection composite layer comprising an elastomer sheath, a multi-point bending monitoring component mounted inside the elastomer sheath, the multi-point bending monitoring component comprising an elastic contact strip and multiple bending monitoring units, the elastic contact strip comprising an elastic protective strip, multiple contact wires mounted on the inner side of the elastic protective strip, the bending monitoring unit comprising a mounting box, a contact base fixedly mounted on the inner side of the mounting box, a varistor fixedly mounted on the upper surface of the contact base, an elastic support plate mounted on the upper surface of the varistor, and an elastic cover mounted on the upper surface of the elastic support plate.

[0006] Preferably, the cable protection composite layer further includes a tinned copper wire braided shielding layer fixedly connected to the inner wall of the elastomer sheath, an environmentally friendly halogen-free flame-retardant glass fiber tape installed on the inner side of the tinned copper wire braided shielding layer, and an aluminum-plastic shielding composite tape fixedly installed between the tinned copper wire braided shielding layer and the environmentally friendly halogen-free flame-retardant glass fiber tape.

[0007] Preferably, the cable protection composite layer is coaxial with the cable mounting layer. The cable mounting layer includes a high-strength lightweight filler rope. Multiple TPU elastomer insulation layers are installed inside the high-strength lightweight filler rope. Thermally conductive fillers are fixedly installed inside the TPU elastomer insulation layers. Multiple tin-plated copper conductors are fixedly installed inside each thermally conductive filler.

[0008] Preferably, a tin-plated copper guide wire is provided between the aluminum-plastic shielding composite tape and the environmentally friendly halogen-free flame-retardant glass fiber tape, the material of the elastomer sheath is B1 grade low smoke halogen-free flame-retardant thermoplastic polyurethane, and the weaving density of the tin-plated copper wire braided shielding layer is not less than 90%.

[0009] Preferably, the elastic contact strip is installed parallel to the axis of the elastic sheath, and the plurality of bending monitoring units are arranged linearly along the axis of the elastic contact strip. The elastic sheath is fixedly connected to the elastic protective strip and the mounting box.

[0010] Preferably, the connecting wire passes through the mounting box and is electrically connected to the varistor via a connecting base; both ends of the elastic support plate are fixedly connected to the mounting box; and the side of the elastic cover is bonded and fixed to the mounting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model effectively prevents high-temperature oxidation by tinning the surface of the tin-plated copper conductor. The use of environmentally friendly halogen-free flame-retardant glass ribbon for binding prevents loosening and deformation, ensuring a high degree of fit and preventing edge curling. An aluminum-plastic shielding composite tape, a tin-plated copper wire braided shielding layer, and an elastomer sheath are installed on the outside of the environmentally friendly halogen-free flame-retardant glass ribbon. The combination of the tin-plated copper wire braided shielding layer and the aluminum-plastic shielding composite tape provides shielding against external electromagnetic field interference, ensuring stability in use. At the same time, the elastomer sheath made of B1-grade low-smoke halogen-free flame-retardant thermoplastic polyurethane prevents dripping during combustion.

[0013] 2. This utility model connects multiple bending monitoring units via an elastic connecting strip. An elastic support plate is installed between the varistor and the elastic cover, so that when the cable bends, the elastic sheath presses on the elastic cover. The elastic cover then causes the elastic support plate to deform and transmits the pressure to the varistor. The varistor then converts the pressure into a corresponding electrical signal. Based on the strength of the electrical signal, the degree of bending at the location of the bending monitoring unit can be measured, thus facilitating accurate monitoring of the bending position and degree of bending of the cable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides an embodiment of a novel bend-resistant polyester halogen-free environmentally friendly explosion-proof shielded control cable, comprising a cable mounting layer 2, a cable protection composite layer 1 installed on the outer side of the cable mounting layer 2, the cable protection composite layer 1 comprising an elastomer sheath 101, a tinned copper wire braided shielding layer 102 fixedly installed on the inner wall of the elastomer sheath 101, an environmentally friendly halogen-free flame-retardant glass ribbon 104 installed on the inner side of the tinned copper wire braided shielding layer 102, an aluminum-plastic shielding composite tape 103 fixedly installed between the tinned copper wire braided shielding layer 102 and the environmentally friendly halogen-free flame-retardant glass ribbon 104, and a tinned copper drain wire provided between the aluminum-plastic shielding composite tape 103 and the environmentally friendly halogen-free flame-retardant glass ribbon 104. The material of the elastomer sheath 101 is B1 grade low smoke halogen-free flame-retardant thermoplastic polyurethane, the braiding density of the tinned copper wire braided shielding layer 102 is not less than 90%, and it can be tightened by the environmentally friendly halogen-free flame-retardant glass ribbon 104 to prevent loosening and deformation, and has a high degree of fit and is not easy to curl up.

[0022] Please see Figure 1 and Figure 2 The cable protection composite layer 1 is coaxial with the cable mounting layer 2. The cable mounting layer 2 includes a high-strength lightweight filler rope 201. Multiple TPU elastomer insulation layers 202 are installed inside the high-strength lightweight filler rope 201. A thermally conductive filler 203 is fixedly installed inside the TPU elastomer insulation layer 202. Multiple tin-plated copper conductors 204 are fixedly installed inside each thermally conductive filler 203. Tin plating on the surface of the tin-plated copper conductors 204 can effectively prevent high-temperature oxidation.

[0023] Please see Figures 3 to 5 The elastomer sheath 101 is equipped with a multi-point bending monitoring component 3. The multi-point bending monitoring component 3 consists of an elastic connecting strip 301 and multiple bending monitoring units 302. The elastic connecting strip 301 is installed parallel to the axis of the elastomer sheath 101. The multiple bending monitoring units 302 are arranged linearly along the axis of the elastic connecting strip 301. The multiple bending monitoring units 302 are connected through the elastic connecting strip 301, which facilitates the multiple bending monitoring units 302 to monitor the degree of bending at multiple points when the cable is bent.

[0024] The elastic connecting strip 301 includes an elastic protective strip 303, with multiple connecting wires 304 installed on the inner side of the elastic protective strip 303. The bending monitoring unit 302 includes a mounting box 305. The elastic sheath 101 is fixedly connected to both the elastic protective strip 303 and the mounting box 305. A connecting base 309 is fixedly installed on the inner side of the mounting box 305. A varistor 308 is fixedly installed on the upper surface of the connecting base 309. An elastic support plate 307 is installed on the upper surface of the varistor 308. An elastic... The cover 306 and the connecting wire 304 pass through the mounting box 305 and are electrically connected to the varistor 308 through the connector 309. The two ends of the elastic support plate 307 are fixedly connected to the mounting box 305. The side of the elastic cover 306 is bonded and fixed to the mounting box 305. When the cable is bent, the elastic sheath 101 applies pressure to the elastic cover 306, which in turn causes the elastic support plate 307 to deform and transmit the pressure to the varistor 308, making it easy to accurately monitor the bending position and degree of bending of the cable.

[0025] In summary, when assembling the bend-resistant polyester halogen-free environmentally friendly explosion-proof shielded control cable, multiple tin-plated copper conductors 204 are sequentially wrapped with a thermally conductive filler 203 and a TPU elastomer insulation layer 202. Tin plating on the surface of the tin-plated copper conductors 204 effectively prevents high-temperature oxidation. Then, high-strength lightweight filler ropes 201 and environmentally friendly halogen-free flame-retardant glass fiber ribbons 104 are sequentially wrapped around the outside of the multiple TPU elastomer insulation layers 202, and finally secured with the environmentally friendly halogen-free flame-retardant glass fiber ribbons 104. It can prevent loosening and deformation, has a high degree of fit and is not easy to curl up. An aluminum-plastic shielding composite strip 103, a tin-plated copper wire braided shielding layer 102 and an elastomer sheath 101 are installed on the outside of the environmentally friendly halogen-free flame-retardant glass ribbon 104. The tin-plated copper wire braided shielding layer 102 and the aluminum-plastic shielding composite strip 103 are combined to shield against external electromagnetic field interference, ensuring the stability of use. At the same time, the elastomer sheath 101, which is made of B1 grade low smoke halogen-free flame-retardant thermoplastic polyurethane, can prevent dripping during combustion.

[0026] Inside the elastomer sheath 101, there is a multi-point bending monitoring assembly 3 consisting of an elastic connecting strip 301 and multiple bending monitoring units 302. The multiple bending monitoring units 302 are connected through the elastic connecting strip 301, which facilitates the multiple bending monitoring units 302 to monitor the degree of bending at multiple points when the cable is bent. Specifically, an elastic support plate 307 is installed between the varistor 308 and the elastic cover 306, so that when the cable is bent, the elastomer sheath 101 applies pressure to the elastic cover 306. The elastic cover 306 then causes the elastic support plate 307 to deform and transmit the pressure to the varistor 308. The varistor 308 then converts the pressure into a corresponding electrical signal. The strength of the electrical signal can be used to determine the degree of bending at the location of the bending monitoring unit 302, thereby facilitating accurate monitoring of the bending position and degree of bending of the cable.
