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 combined anti-interference 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 of the components of the electronic control equipment to be blocked, resulting in unusable or even scrapped. Anti-interference performance is an important technical indicator of data cable products and plays a vital role in data transmission; however, traditional data cables are mostly anti-interference structures directly set on the outside of the core when performing anti-interference processing. The disadvantage of this processing method is that its anti-interference ability is limited, and the suppression and protection effect on some high-frequency interference signals is not ideal, resulting in it being susceptible to external interference signals under specific interference conditions and complex electromagnetic environments, resulting in reduced or interrupted data transmission quality, and attenuation and distortion of signal transmission.

[0020] 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.

[0021] See also Figure 1~Figure 2 A preferred embodiment of a combined anti-interference data cable is provided. The combined anti-interference data cable of this embodiment can be used in high-frequency interference signal conditions or complex electromagnetic conditions. The cable body includes a wire body and connectors formed at both ends of the wire body. The size and material of the wire body and the type of connectors at both ends of the wire body can be set according to the corresponding requirements of the device.

[0022] The wire body of this embodiment includes eight individually formed conductors 2, and the eight conductors 2 are arranged in a straight line on the cross-section of the wire body. The conductors 2 constitute the functional part of the wire row, which includes a wire core formed of a silver-plated copper monofilament and a cortex that wraps the wire core. The cortex is made of a thermoplastic polyurethane elastomer rubber material, and the adjacent conductors are connected through the cortex. The combination of the thermoplastic polyurethane elastomer cortex makes the wire row have good elasticity and buffering effect, and can effectively absorb and disperse the stress during the bending process.

[0023] In another embodiment, the conductor 2 can also be formed with an outer fiber fabric on the outside of the cortex. The outer fiber fabric can be a mesh polyester fiber fabric or a mesh nylon fiber fabric. The outer fiber fabric can further improve the mechanical strength of the conductor. At the same time, the mesh structure of the outer fiber fabric can also cooperate with the filler 7 to fill the gaps between the conductors, thereby increasing the overall stability of the conductor.

[0024] The eight wires 2 arranged in a row are formed with a first anti-interference structure on the outer side of the whole, and the first anti-interference structure includes two nylon fabric layers 6 and a polypyrrole fiber fabric layer 9 formed between the nylon fabric layers 6, wherein the nylon fabric layer 6 is a dipped fabric layer, and a layer of chopped aramid fibers is evenly dispersed between the two side surfaces of the polypyrrole fiber fabric layer 9 and the nylon fabric layer by blowing to obtain a chopped aramid fiber layer 8.

[0025] The nylon fabric layer 6, as the outer layer of the first anti-interference structure, can fix the polypyrrole fiber fabric layer 9 and the chopped aramid fiber layer 8. It has good mechanical strength and wear resistance, and can effectively resist external physical interference. The polypyrrole fiber fabric layer 9 has good conductivity, can absorb and disperse high-frequency interference signals, thereby significantly improving the anti-interference ability of the data cable. The chopped aramid fibers in the chopped aramid fiber layer 8 can form a spatial cross-linked structure by passing through the mesh surface of the nylon fabric layer 6 and the polypyrrole fiber fabric layer 9 during the molding process, further enhancing the bonding force between the nylon fabric layer 6 and the polypyrrole fiber fabric layer 9, and ensuring the integrity and stability of the first anti-interference structure.

[0026] In this embodiment, the entire first anti-interference structure is a preformed structure, which is preformed into one piece by hot pressing after the above structure is stacked and formed, so as to fix the polypyrrole fiber fabric layer 9 and the short-cut aramid fiber 8, prevent them from displacement or falling off during use, and improve the stability and durability of the first anti-interference structure. In other embodiments, the polypyrrole fiber fabric layer 9 can also be sewn together with at least one layer of nylon fabric layer 8 to obtain a similar effect.

[0027] Furthermore, in order to further improve the stability and durability of the first anti-interference structure, a layer of epoxy resin adhesive layer 5 is also formed on the outer surface of the first anti-interference structure. The epoxy resin adhesive layer 5 seals the various structural layers of the first anti-interference structure inside to achieve protection from the outside world. At the same time, the epoxy resin adhesive layer 5 can also form a smooth film layer on the surface of the first anti-interference structure, which is convenient for the subsequent molding and installation of the second anti-interference structure.

[0028] A protective wire sleeve 1 is formed on the outside of the first anti-interference structure. The protective wire sleeve 1 is a plastic structure sheath. A metal fabric mesh 4 is formed on the inside of the protective wire sleeve 1 as a second anti-interference structure. The metal fabric mesh 4 is a mesh structure formed by weaving metal wires, which can shield electromagnetic signals. At the same time, the second anti-interference structure can also achieve physical protection for the first anti-interference structure, avoid the first anti-interference structure from external physical damage, and extend its service life.

[0029] In different embodiments, the metal fabric mesh 4 is formed inside the protective wire sleeve 1 in two ways:

[0030] First, as shown in the embodiment, a buffer structure layer 3 is formed between the metal fabric mesh 4 and the protective wire sleeve 1. The material of the buffer structure layer 3 is an elastic plastic structure with a hardness lower than that of the protective wire sleeve 1. The material can be selected from one of the three elastic materials of TPEE, CR, and TPV. The setting of the buffer structure layer 3 can protect the metal fabric mesh, avoid friction and collision between the metal fabric mesh and the protective wire sleeve, and extend its service life.

[0031] In another embodiment, the metal fabric mesh 4 can be directly molded on the inner side of the protective wire sleeve 1 at an interface position corresponding to the protective wire sleeve 1 by melt adhesive. In addition, a layer of perforated polyimide film layer can be molded on the surface of the metal fabric mesh 4, and the perforated polyimide film layer can further improve the electromagnetic shielding effect of the metal fabric mesh 4, and its perforated structure is used to achieve spatial structural cross-linking.

[0032] The combined anti-interference data cable of this embodiment can achieve double anti-interference protection during wire transmission through the combination of the first anti-interference structure and the second anti-interference structure, thereby improving the stability and accuracy of data transmission. At the same time, the elastic structure and buffer structure of the wire body can also increase the bending resistance and durability of the wire body, thereby increasing the service life of the wire body.

[0033] 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. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
