Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Referring to Fig. 1, in the utility model embodiment, the counter-bending electric wire waved after a kind of improvement, including cable 1, the outer surface of cable 1 be provided with it is outer by 2, it is outer to be internally provided with braiding layer 3 by 2, be provided with braiding layer 3 some signal wires 4, Four ground wires 5 and some filling wire rods 10, signal wire 4 include the wire rod 8 of eight root product one and the wire rod 9 of seven root product two, component One wire rod 8 includes white signal line, brown signal wire, blue signal line, danger signal line and green line, the wire rod of component two 9 include black signal line, green line, brown signal wire, yellow signal line, white signal line, blue signal line and red Signal wire, it is integral that ground wire 5 respectively carries out pair twist with the wire rod 8 of two root product one with pair twister, ground wire 5 respectively with two signals The lay of line 4 carries out pair twist according to 18.4 plus-minus 1mm, and ground wire 5 and the pair twist outer layer of signal wire 4 are set to winding layer 6, the winding layer 6 be that two layers of single line footpath is the winding of 0.08mm copper wires, and inner side copper wire winding direction be Z-direction, outside copper wire winding direction for S to, The winding of both direction makes wire rod bend in which direction all can share a part of pulling force by the copper wire wound, copper wire Line footpath and radical can be designed adjustment according to different requirements, and the copper wire wound belongs to metallic shield and substitutes aluminium foil Shield effectiveness can make the characteristic impedance of signal pair meet the characteristic impedance requirement of 10 ohm of the plus-minus of association 100, and have anti-dry The performance disturbed, the outermost layer of winding layer 6 wrap up one layer of adhesive-bonded fabric 7, prevented to the short circuit between signal shielding line, this cable signal line 4 in bending some activity spaces, and the copper wire of winding layer 6 can also share some pulling force, cable 1 is acted on by external force curved The extent of damage of signal wire 4 is minimum when bent, can reach waving for secondary even hundreds of thousands time up to ten thousand, and improve cable 1 uses the longevity Life, improves HDMI wire material intolerant to the characteristic waved.
