Interior to be provided with some some signal wires, four ground wires filling wire rods, the signal wire includes the wire rod of eight root product one and seven
The wire rod of component two, the ground wire is respectively twisted integral with the wire rod of two root product one, is set describedly with signal wire pair twist outer layer
For winding layer, the winding layer outermost layer wraps up one layer of adhesive-bonded fabric.
As further program of the utility model:The wire rod of component one includes white signal line, brown signal wire, indigo plant
Chrominance signal line, danger signal line and green line, the wire rod of component two include black signal line, green line, brown signal
Line, yellow signal line, white signal line, blue signal line and danger signal line.
As further program of the utility model:The ground wire is respectively with two signal wire lays according to 18.4 plus-minuss
1mm carries out pair twist.
As further program of the utility model:The winding layer is that two layers of single line footpath is the winding of 0.08mm copper wires,
Inner side copper wire winding direction is Z-direction, outside copper wire winding direction be S to.
Compared with prior art, the utility model beneficial effect:
The counter-bending electric wire waved after this improvement, make some activity spaces in bending of signal wire 4, and winding layer
6 copper wire can also share some pulling force, and cable 1 is acted on by external force when bending, the extent of damage of signal wire 4 is minimum, can reach
Waving for secondary even hundreds of thousands time up to ten thousand, improves the service life of cable 1, improves HDMI wire material intolerant to the characteristic waved.

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
