Description

Technical Field

[0001] The utility model relates to a data line manufacturing technology in the technical field of data transmission, in particular to a bending-resistant data cable. Background Art

[0002] As a cable structure responsible for transmitting data and power in electronic control equipment, data cables are important connecting links between electrical components inside electronic control equipment. They can be used to connect active parts and components in active areas for multi-channel data transmission and power supply. There are many types of data cables in the prior art, and some manufacturers will customize corresponding data cables according to their own equipment requirements; but they all include a wire body and connectors formed at both ends of the wire body. The wire body can arbitrarily select the number and spacing of wires according to actual needs, making wiring more convenient.

[0003] As the most basic component of electronic circuits, the quality of data cables greatly affects the final quality of the entire electronic control equipment. Defects in the cables will cause data transmission or power consumption obstacles in the components of the electronic control equipment, resulting in unusable or even scrapped. Among them, since data cables are mostly used for soft connections between sub-devices and electrical components inside the equipment, their bending resistance is also an important technical indicator of their products. If the bending resistance is poor, the probability of deformation and damage of the cables during use will increase, resulting in poor practicality and reliability, and cannot meet application requirements. Although the existing data cables can meet the normal bending needs of customers to a certain extent, for some medium and large electronic control equipment, due to the large number of connecting lines between sub-devices and components inside, and the relatively more complex use environment, customers' requirements for the bending resistance of data cables are also constantly increasing. For some high-end products and products in specific usage scenarios, they have clear requirements for the curvature, number of times, dynamic direction, etc. of the bending, so a data cable with better bending resistance is needed to meet market demand. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a bending-resistant data cable to solve the problem of insufficient bending resistance of data cables used in medium and large-sized equipment in the prior art, improve the practicality and reliability of the data cables, and meet the bending resistance requirements of high-end products and products in specific usage scenarios for data cables.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-2 A preferred embodiment of a bend-resistant data cable is provided. The bend-resistant data cable of this embodiment can be used in industrial mother machines with poor operating environments. The cable includes a wire body and connectors formed at both ends of the wire body. The size and material of the wire body and the types of connectors at both ends of the wire body are set according to the corresponding requirements of the equipment.

[0023] The wire body of this embodiment includes eight individually formed conductors 1, and the eight conductors 1 are arranged in an arc shape on the cross section of the wire body to obtain a wire row. The structure of the wire row is as follows: Figure 1 As shown, the arc surface corresponds to an arc surface with an angle of 5°, and the line row is formed with an elastomeric pad 4 on the concave side of the arc surface. The elastomeric pad 4 is a rubber body in this embodiment. The setting of the elastomeric pad 4 not only enhances the overall structural strength of the line row, but also makes the line row have good elasticity and buffering effect, which can effectively absorb and disperse the stress in the bending process, and further protect the overall anti-bending performance of the line row composed of the conductor 1.

[0024] The outer side of the wire row and the elastomeric liner 4 is wrapped with a sheath 3. In the present embodiment, the sheath 3 is a plastic sheath, which is directly formed on the outer surface of the wire row and the elastomeric liner 4, and a layer of impregnated polyester fiber fabric is formed on the inner side of the plastic sheath as a structural lining. The structural lining is directly attached to the upper surface of the wire row and the lower surface of the elastomeric liner 4 to protect the conductor 1 and the elastomeric liner 4, and also makes the entire wire body have good wear resistance and corrosion resistance, and can adapt to various harsh use environments.

[0025] In this embodiment, the eight conductors 1 that make up the line row are also structurally reinforced. Specifically, a single conductor 1 includes a core 9 and a structural reinforcement layer that outwrapped the core 9. The core 9 is a conventional conductor material on the market. The structural reinforcement layer includes a lining material 8 that is directly outwrapped on the surface of the core 9. The lining material 8 is formed of an elastic plastic material. In this embodiment, it is preferably made of TPEE elastic material. Of course, it can also be made of one of the two elastic materials CR and TPV. The thickness of the lining material 8 is 1 / 10 of the diameter of the core 9.

[0026] A bending-resistant reinforcement layer is formed on the surface of the lining material 8, and the bending-resistant reinforcement layer includes a reinforcing fabric 7. A plurality of spring steel monofilaments 6 are formed on the outer surface of the reinforcing fabric 7. The reinforcing fabric 7 is a fabric structure woven with nylon as the warp and polytetrafluoroethylene fiber as the weft. When the reinforcing fabric 7 is formed, the warp is arranged along the circumferential direction of the wire core 9, and the weft is arranged along the length direction of the wire core 9; the cross-section of the spring steel monofilament 6 is a flat structure that fits the surface of the reinforcing fabric 7, is woven together with the reinforcing fabric 7, and is evenly arranged on the outer annular surface of the reinforcing fabric 7; an outer sheath layer 5 made of PVC is formed on the outer surface of the bending-resistant reinforcement layer.

[0027] The conductor 1 of the bend-resistant data cable of this embodiment can significantly enhance the structural strength of the core 9 through the outer lining material 8, thereby preventing the core 9 from breaking or being damaged during the bending process; at the same time, the elastic material properties of the lining material 8 make the conductor 1 have good elasticity and buffering effect, which can effectively absorb the stress during the bending process and protect the core 9 from damage.

[0028] In addition, the provision of the reinforcing fabric 7 further improves the bending resistance of the conductor 1. The mesh structure formed by the interweaving of the warp and weft of the reinforcing fabric 7 can effectively disperse the bending stress and also has good tensile strength and wear resistance; it prevents the conductor 1 from having obvious creases or breaks during the bending process; at the same time, the material selection of the reinforcing fabric 7 also ensures that it has good wear resistance and corrosion resistance, and can adapt to various harsh use environments; the spring steel monofilament 6 is evenly arranged on the outer ring surface of the reinforcing fabric in a flat structure, which can effectively absorb and disperse the stress during bending, further enhancing the bending resistance of the conductor 1. The flat structure of the spring steel monofilament 6 enables it to fit tightly on the outer surface of the reinforcing fabric 7 to form a continuous and stable support structure, which effectively supports and protects the conductor 1 from damage during the bending process.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
