Problems solved by technology

The core wire of this kind of process structure wire and the swing performance of the final product can only meet the general requirements of the market and customers, and cannot meet the requirements of customers and markets with swing requirements of 200,000 or even 500,000 times.
Moreover, in the traditional process, the signal lines are all twisted and then assembled into a wire harness. The process is relatively complicated and the cost is relatively high.

Embodiment 1

[0030]In this embodiment, the ingredients (wt.%) of the sheath layer of the computer digital signal transmission line are: 40% of polyvinyl chloride granules; 28% of trioctyl trimellitate; 10% of calcium carbonate powder; kaolin powder 5%; environment-friendly calcium-zinc composite stabilizer 1.5%; stearic acid 0.05%; styrene-butadiene rubber 9%; flame retardant 1.5%; toner 0.5%; 1000, the particle size of calcium carbonate powder is 70 microns, and the particle size of kaolin powder is 20 microns. The glass beads, calcium carbonate powder and kaolin powder in the above raw materials are fully soaked for 30 minutes after passing through the silane coupling agent (the amount of the silane coupling agent is 10% of the total volume of the glass beads, calcium carbonate powder and kaolin powder). After that, it should be circulated at room temperature, ventilated and dried in the shade, and then mixed. When mixing, it should be added into the mixer in the following order: a. PVC ...

Embodiment 2

[0032] In this embodiment, the ingredients (wt.%) of the sheath layer of the computer digital signal transmission line are: 43% of polyvinyl chloride granules; 30% of trioctyl trimellitate; 12% of calcium carbonate powder; kaolin powder 4%; environment-friendly calcium-zinc composite stabilizer 1.7%; stearic acid 0.13%; styrene-butadiene rubber 10%; flame retardant 2.1%; toner 0.7%; 1100, the particle size of calcium carbonate powder is 78 microns, and the particle size of kaolin powder is 25 microns. The glass beads, calcium carbonate powder and kaolin powder in the above raw materials are fully soaked for 30 minutes after passing through the silane coupling agent (the amount of the silane coupling agent is 20% of the total volume of the glass beads, calcium carbonate powder and kaolin powder). After that, it should be circulated at room temperature, ventilated and dried in the shade, and then mixed. When mixing, it should be added into the mixer in the following order, a. PV...

Embodiment 3

[0034] In this embodiment, the ingredients (wt.%) of the sheath layer of the computer digital signal transmission line are: 41% of polyvinyl chloride granules; 27% of trioctyl trimellitate; 13.6% of calcium carbonate powder; kaolin powder 3.4%; environment-friendly calcium-zinc composite stabilizer 2.0%; stearic acid 0.07%; styrene-butadiene rubber 8%; flame retardant 2.5%; toner 0.9%; 1300, the particle size of calcium carbonate powder is 80 microns, and the particle size of kaolin powder is 30 microns. The glass beads, calcium carbonate powder and kaolin powder in the above raw materials are fully infiltrated for 30 minutes by silane coupling agent (the amount of silane coupling agent added is 25% of the total volume of glass beads, calcium carbonate powder and kaolin powder) After that, it should be circulated at room temperature, ventilated and dried in the shade, and then mixed. When mixing, it should be added into the mixer in the following order, a. PVC granules with 40...

Abstract

The invention discloses a digital signal transmission line for a computer. The digital signals transmission line comprises a sheathing layer, a conductive metal wire braid layer, a hot-melting aluminum foil layer, a mylar, a ground wire, an electronic wire and a signal wire, wherein the sheathing layer mainly comprises the following raw materials: 40-45 wt% of polyvinyl chloride particle material, 27-32 wt% of trioctyl trimellitate, 10-15 wt% of a filling material, 1.5-2 wt% of an environment-friendly Ca-Zn composite stabilizer, 0.05-0.13 wt% of stearic acid, 8-10 wt% of styrene-butadiene rubber, 1.5-2.5 wt% of a flame retardant, 0.5-1.0 wt% of toner, and 3-5 wt% of glass microspheres; the degree of polymerization of the polyvinyl chloride is 1000-1300. The transmission line is simple in production technology, low in cost, simple in structure, and resistant to swinging, and has favorable tensile property.

Description

technical field [0001] The invention relates to a signal transmission line, in particular to a digital signal transmission line for a computer. Background technique [0002] With the development of communication technology, portable terminals can not only provide users with voice calls and short message services in the traditional sense, but also provide users with various services such as video calls, moving image services, and mobile banking. In addition, since mobile communication services are developed toward multimedia services such as moving image services, the performance of antennas becomes an important factor in the signal quality of portable terminals. Conventional antennas usually protrude outward from the portable terminal. As a result, the antenna is likely to be damaged by external impact or not portable, and the diversification of design of the portable terminal is limited. In addition, users have higher and higher requirements on the appearance of portable ...
