Four groups of band line arrangement modes are pressed ground wire arranged in a crossed manner up and down, can be corresponding with the wire rod socket end wiring position arrangement of high-frequency signal transmission wire, its direct effect is that ground wire and linear position data are tried one's best near reducing the core property difference and promoting differential impedance.
The utility model has following beneficial effect compared with the prior art:
1. the connection-peg that is connected with wiring board of the structure of platypelloid type transmission line adapts for the yi word pattern structure; The structural stability of platypelloid type structural transmission line is better than the circular configuration transmission line.
2. the staggered mode of ground wire can be arranged correspondingly, easy to use with the wire rod socket end wiring bit position of high-frequency signal transmission wire, also is convenient to processing;
3. multiple isolation, shielding coat and the ground line position is staggeredly equipped with to be beneficial to and promotes wire rod differential impedance stability, and reducing wire rod, that Inner is prolonged Time is poor, improve the ability of wire rod transmitting high-frequency signal and reduce and go here and there noise.
Description of drawings
Fig. 1 is a kind of embodiment front view of the utility model;
Embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment: as shown in Figure 1, a kind of flat high-speed transfer line structure, the high-frequency signal core strand that comprises the coated insulation layer is to, ground wire, communication twisted wire group, screen and outer wrap, the utility model screen and outer wrap inside are set to a Ge flat pattern cavity, flat pattern cavity Inner place at least two group band high-frequency signal cores strand to unit 1 be no less than a group communication twisted wire group 3; All be provided with ground wire 2 in described each band high-frequency signal core twists the unit, ground wire is positioned at band high-frequency signal core strand to unit one side, and from the section of cable, ground wire becomes the isosceles triangle setting with two cores; Band high-frequency signal core twists, and adjacent band high-frequency signal core strand is located at upside and is located at downside the ground wire in the unit and staggers mutually, and for example one, three unit ground wires are located at upside, and two, four unit ground wires then are located at downside.
