Description

Technical Field

[0001] The utility model relates to the technical field of vehicle electric wires, in particular to a high-flexibility ABS sensor cable. Background Art

[0002] ABS sensors are used in the anti-lock braking system of motor vehicles. Most of them use electrical sensors to monitor vehicle speed, which places high performance requirements on cables that undertake signal transmission functions. ABS sensor cables should have high sensitivity and fast response time to ensure that the ABS system can accurately and promptly respond to changes in the vehicle's driving status. The cables should also have small resistance and capacitance to reduce signal loss and interference.

[0003] In actual applications, due to complex road conditions and frequent turns, the driving state of the car is uncertain, and the ABS cable is subjected to large bending and tensile stresses. If the cable is not flexible enough, it is easy to cause the internal line of the cable to break or be damaged, affecting the signal transmission quality and the reliability of the ABS system. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a high-flexibility ABS sensor cable, enhance the flexibility and wear resistance of the cable, increase the service life of the cable, and improve the reliability and safety of the ABS system.

[0005] The purpose of the utility model is achieved as follows: a high-flexibility ABS sensor cable, comprising a plurality of core wires, the outside of the core wires being covered with an insulating layer, the outside of the insulating layer being covered with a spiral sheath, the core wires being composed of a bulletproof wire arranged at the center of the core wire and a multi-layer twisted conductor wrapped around the outside of the bulletproof wire.

[0006] Furthermore, the conductor is made of three layers of pure copper conductors with a single wire diameter not exceeding 0.1 mm, six conductors are tightly wrapped around the bulletproof wire in the center of the core wire, twelve conductors are tightly wrapped around the six conductors, and eighteen conductors are tightly wrapped around the twelve conductors.

[0007] Furthermore, the insulating layer is made of TPE material, the insulating layers outside adjacent core wires are in contact with each other, and the thickness of the insulating layer is 0.5 mm.

[0008] Furthermore, the sheath is made of polyether TPU material, the sheath is tightly wrapped around the outer surface of the cable in a spiral shape, and the thickness of the sheath is 1-1.4 mm.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] First, a spiral sheath is wrapped around the outside of the cable. The spiral shape can guide the cable along a smoother path when it bends, avoiding sharp bending angles, increasing the bending radius of the cable, reducing stress concentration, and alleviating cable wear during bending.

[0011] Second, a bulletproof wire is set in the center of the core wire and twisted with the conductor to enhance the high tensile strength and high pulling force of the cable conductor. When the cable is bent or deformed, it can effectively improve the durability of the conductor to external forces and avoid the conductor from being broken or damaged by external forces.

[0012] Third, the sensor cable of the present invention uses high-purity copper conductors with a purity requirement of more than 99.99%, which improves the flexibility of the conductor, ensures the flexibility and bendability of the cable, and also ensures excellent conductive efficiency, signal transmission quality and reliability of the ABS system.

[0013] Fourthly, the sensor cable of the present invention has a simple structure, is made of readily available materials, and has a simple manufacturing process, and is suitable for use as a cable in an automobile ABS system. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the above picture, 1 is bulletproof wire, 2 is conductor, 3 is insulation layer, and 4 is sheath. DETAILED DESCRIPTION

[0017] like Figure 1 、 2 A highly flexible ABS sensor cable is shown, comprising a plurality of core wires, each of which is covered with an insulating layer 3, which is covered with a spiral sheath 4. The core wire is composed of a bulletproof wire 1 arranged at the center of the core wire and a multi-layer twisted conductor 2 wrapped around the bulletproof wire 1.

[0018] The conductor 2 is made of three layers of pure copper conductors with a single wire diameter not exceeding 0.1 mm. Six conductors 2 are tightly wrapped around the bulletproof wire 1 in the center of the core wire, twelve conductors 2 are tightly wrapped around the six conductors 2, and eighteen conductors 2 are tightly wrapped around the twelve conductors 2. By using high-purity copper conductors with a purity of more than 99.99%, excellent conductivity is ensured, the flexibility of the conductor is improved, the flexibility and bendability of the cable are guaranteed, and the signal transmission quality and the reliability of the ABS system are guaranteed.

[0019] The insulating layer 3 is made of TPE material. The insulating layers 3 on the outside of adjacent core wires are in contact with each other, and the thickness of the insulating layer 3 is 0.5mm. TPE is a thermoplastic elastomer with excellent insulation performance. It can isolate the current inside the cable from the external environment, ensuring that the cable can operate safely and stably in a complex working environment and guaranteeing the quality of signal transmission. In addition, the molecular structure of TPE material is stable and its anti-aging performance is excellent. It can maintain stable performance even at high temperatures, avoiding the cable from failing due to heat aging. At the same time, TPE has a soft touch, which enables the cable to adapt to various installation environments and improves the wear resistance of the cable.

[0020] The sheath 4 is made of polyether-type TPU material. The sheath 4 is spirally wrapped tightly around the outer surface of the cable, and the thickness of the sheath 4 is 1~1.4 mm. The polyether-type TPU is a thermoplastic polyurethane elastomer with high wear resistance and bending fatigue resistance. It can effectively protect the cable from external mechanical damage, extend the service life of the cable, and protect the integrity of the cable. In addition, the polyether-type TPU material has a low odor and low VOC content. It is a green and safe sheath raw material and can be recycled, which meets the requirements of environmental protection and sustainable development in automobile manufacturing.

[0021] When the utility model is working, the high-purity copper wire conductor 2 is twisted in three layers according to the arrangement of "6-12-18", a bulletproof wire 1 is arranged at the center of the three-layer conductor 2, six conductors 2 are tightly arranged on the periphery of the central bulletproof wire 1, twelve conductors 2 are tightly wrapped around the six conductors 2, and eighteen conductors 2 are tightly wrapped around the twelve conductors 2. When the cable is made, the bulletproof wire 1 and the outer three-layer conductor 2 are twisted in the same direction at the same time. By twisting the bulletproof wire 1 with the conductor 2, the high tensile strength and high pulling force of the conductor 2 are enhanced. When the cable is bent or deformed, the durability of the conductor 2 to the external force can be effectively improved, and the conductor 2 can be prevented from being broken or damaged by the external force; the outermost conductor 2 is tightly wrapped The insulating layer 3 made of TPE material can isolate the current inside the cable from the external environment, ensuring that the cable operates safely and stably in complex working environments and guaranteeing the quality of signal transmission. In order to improve the adaptability of the ABS sensor cable to bending, the sheath 4 is wrapped around the cable surface in a spiral shape. The spiral shape can guide the cable along a smoother path when bending, avoiding sharp bending angles, increasing the bending radius of the cable, reducing stress concentration, and thus reducing the wear of the cable during bending. In addition, the sheath 4 made of polyether TPU material has high wear resistance and resistance to bending fatigue, which can effectively protect the cable from external mechanical damage, extend the service life of the cable, and protect the integrity of the cable. The cable structure of this device is simple, the manufacturing materials are easily available, and the manufacturing process is simple, making it suitable for use in the transmission of automobile ABS systems.
