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.

Abstract

The invention discloses a bending-resistant shielded transmission line which includes a sheathing layer, a braid layer, a hot-melt aluminum foil layer, a filling line and a signal line. The shielded transmission line is characterized in that the sheathing layer includes the following main raw materials in percentage by weight: 40-45% of polyvinyl chloride powder, 27-32% of trioctyl trimellitate, 15-17% of a filling material, 1.5-2% of an environment-friendly Ca-Zn composite stabilizer, 0.05-0.13% of stearic acid, 8-10% of polystyrene rubber, 1.5-2.5% of a flame retardant and 0.5-1.0% of toner, wherein the polymerization degree of polyvinyl chloride is 1000-1300. The bending-resistant shielded transmission line provided by the invention is simple in manufacturing technology, low in cost, simple in structure and resistant to swing, and has a good tensile property.

Description

technical field [0001] The invention relates to a signal transmission line, in particular to a bending-resistant shielded transmission line. 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 ter...
