[Prior Art] In order to meet the transmission requirements of low-voltage differential signaling (LVDS), the conductor to be transmitted lvds must have 100Ω characteristic impedance and controlled electromagnetic interference to correctly transmit the signal command, otherwise signal reflection and noise will be generated. Interference, resulting in signal loss, distortion and distortion. In general, the wires that carry LVDS can be conventional parallel, flexible printed circuit boards, coaxial cables, and the like. However, the cost of flexible printed circuit boards and coaxial cables is relatively high, and although the parallel line is low in cost, it is prone to electromagnetic interference. In order to solve the problem of electromagnetic interference in parallel, many manufacturers have proposed anti-leg shielding housings. For example, U.S. Patent Nos. 6,616,086 and 6,179,962 are all such prior art. However, such a shielded enclosure will increase the space occupied by the transmission line, and in some applications it is not allowed to be too bulky, making such a shielded enclosure unsuitable for use. Although the Twisted Pair Cable has a good effect on the control of electromagnetic interference, it is also inexpensive. However, because of the spacing and gaps between the two intertwined wires in the twisted pair, the control of the characteristic impedance of the twisted pair is not ideal. Twisted pair is a kind of wire made by two mutually insulated wires entangled with each other according to certain specifications (usually wound with cis 5 M322599 hour hand). Twisted-to-go is mainly used to transmit analog signals, but now it is also suitable for digital transmission. The two insulated copper wires are mutually reduced in the - gorge, which reduces the degree of interference, and the electric wave radiated by each wire in the transmission is cancelled by the electric wave emitted on the other line. For details of the double-strand line, see U.S. Patent No. 4,486,619. In order to achieve low cost and simultaneously control the characteristic impedance and electromagnetic interference, the creator of the present invention proposed a transmission line that integrates the characteristic structure of the twisted wire and the parallel wire. [New content] The main purpose of this creation is to provide a transmission line that can be difficult to impedance and electromagnetic interference. It has the characteristic structure of stranded and parallel lines, and realizes simultaneous regulation of characteristic impedance. 2 Electromagnetic interference p sound is based on the above purpose. 'This creation can simultaneously regulate the characteristic impedance and electromagnetic interference of the transmission line, the transmission line is at least two wires are mixed into ' and the two wires are mutually twisted along the longitudinal axis of the transmission line. In the creation of the transmission line, in addition to twisting the transmission lines with each other (for example, the twisted material controls the electromagnetic interference material, and the transduction guides the recordings to have a clear:, and then control the characteristic impedance. About the creation of the gamma and the fine shot by the following Clear-type slaves _ to further understanding.

As shown in Figure 1 of the figure, an insulative skin survey is provided which is provided with a parallel type of energy line l〇a and a covered metal line 1〇a. It is important to note that the 1G of the upper and the far-line Wei is the same as the handle line. The side transmission line 1〇 has no gap between them, but can control the characteristic impedance and then make the same. In the transmission line 1A of Fig. 1A, the two wires are mutually twisted along the longitudinal axis of the transmission line 1, as shown in Fig. 1. In this way, the transmission of the office is based on the twisted wire structure, and the electromagnetic interference can be controlled. Compared with the conventional double doubling line, the original transmission line 1 shown in Fig. 1 has an additional twisted wire structure and can control electromagnetic interference. The twisting offset of the two wires along the longitudinal axis of the transmission line 1 affects the control effect of electromagnetic interference. φ is compared with the conventional twisted pair. The original transmission line 1 shown in Fig. 1 has an additional collinear structure and can control the characteristic impedance. The distance between the metal wires 1〇a and the characteristic impedance constant of the insulating skin 10b of the two wires affects the control effect of the characteristic impedance. Therefore, the original transmission line 1 as shown in Fig. 1B realizes simultaneous regulation of characteristic impedance and electromagnetic interference based on the characteristic structure in which the domains have twisted, lined, and collocated lines.
