fig. 2 is a schematic structural view of a tensile member of the anti-tensile flat cable of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, an anti-stretching flat cable includes a plurality of conductors 10, an insulating layer 11 and a sheath layer 12 disposed outside the conductors 10, the plurality of conductors 10 are disposed in the sheath layer 12, and an elastic material 13 is filled in the sheath layer 12.

Referring to fig. 1 and 2, two tension members 14 are further disposed in the sheath layer 12, the tension members 14 are respectively disposed on two sides of the conductor 10, each tension member 14 includes a plurality of tension rods 141, and the tension rods 141 are sequentially linearly arranged.

The two ends of the stretching rod 141 are respectively provided with a first collar 142 and a second collar 143, the first collar 142 and the second collar 143 are respectively sleeved outside two adjacent stretching rods 141, the first collar 142 is in contact with the second collar 143 on the adjacent stretching rod 141, and the second collar 143 is in contact with the first collar on the adjacent stretching rod 141.

When the flat cable is stretched during use, the tensile member 14 in the sheath layer 12 serves the purpose of resisting the tension. When the flat cable is stretched, the first loop 142 and the second loop 143 at both ends of the stretching rod 141 slide on the adjacent stretching rods 141, respectively, so that the first loop 142 at one end of the stretching rod 141 is caught by the adjacent second loop 143, and the second loop 143 at the other end of the stretching rod 141 is caught by the adjacent first loop 142.

Therefore, the tensile member 14 is in a tensioned state, and the first sleeve ring 142 and the second sleeve ring 143 of the tensile member 14 are in clamping fit with each other, so that the tensile resistance of the flat cable is improved, and the flat cable is not easy to break due to stretching.
