It cuts cable and is equipped with the first conducting wire bending part and the second conducting wire bending part, the first conducting wire bending part to the flexible flat point
Cut cable one end between and the second conducting wire bending part to the flexible flat cutting cable the other end between be flat
Row end, the conducting wire of some or all of the first conducting wire bending part and the second conducting wire bending part conducting wire and the parallel ends
Between be equipped with angle, if cutting is the part between the first conducting wire bending part and the second conducting wire bending part along its length
Dry conducting wire cuts item, and every conducting wire cutting item includes several conducting wires, is located at the first conducting wire bending part, the second conducting wire
The section of the conducting wire of bending part and conducting wire cutting item is circle, and the section positioned at the conducting wire of the parallel ends is flattened rectangular
Shape.
Further, the section of the conducting wire is the part that the section of circular part and the conducting wire is flattened rectangular shape
It is integrally formed.
Further, conducting wire described in each item of the cutting of conducting wire described in single item is arranged in parallel and spacing is equal.
Further, conducting wire described in each item positioned at the parallel ends is arranged in parallel and spacing is equal.
Further, the notch of the exposed conducting wire is equipped with positioned at the insulating layer of the parallel ends.
Further, the surface of insulating layer at the both ends of the flexible flat cutting cable is equipped with stiffening plate.
The advantages of the present invention over the prior art are that: the conductor cross-section of parallel ends is flattened rectangular shape, and from the
One conducting wire bending part starts to the section of the conducting wire of the second conducting wire bending part to be circle, and first bending point of conducting wire is in flat square
The tie point of shape conducting wire and round conductor, can to avoid conducting wire spacing change (constituting multiple lead units) when conducting wire in life
It produces and deviates center in the wire casing of equipment, can guarantee that the spacing between each conducting wire of parallel ends is stablized, it is raw to improve product
Produce yield, it is ensured that product electric property is stablized.

Specific embodiment
Below with reference to embodiment, the invention will be further described, but not as a limitation of the invention.
Cut a cable incorporated by reference to flexible flat that shown in Fig. 1 to Fig. 3, the present embodiment is related to, if including insulating layer 1 and
The dry conducting wire 2 being arranged in juxtaposition, about 1 insulating layer, which fits, is fixed on conducting wire 2 between insulating layer 1, and insulating layer 1 generally selects heat
Melten gel film such as PET film, covering insulating layer fixes 2 positions of each conducting wire and mutually insulated on conducting wire, while improving flexibility
The flexibility of flat cutting cable entirety.
Flexible flat cuts a cable and is equipped with the first conducting wire bending part A and the second conducting wire bending part B, it should be pointed out that
Be, so-called first conducting wire bending part A and the second conducting wire bending part B be not necessarily referring to flexible flat cutting cable integrally carry out it is curved
Folding, and refer to that the conducting wire 2 inside insulating layer 1 is bent.First conducting wire bending part A cuts one end of a cable to flexible flat
Between and the second conducting wire bending part B between the other end of flexible flat cable be parallel ends C, each item of parallel ends C
Conducting wire 2 is arranged in parallel and spacing is equal, and the section positioned at the conducting wire 2 of parallel ends C is flattened rectangular shape.Parallel ends C's is exhausted
Edge layer 1 is equipped with the notch 1a of nuditing wire, forms the golden hand connecting with other electricity pieces by the exposed conducting wire 2 of notch 1a
Refer to.1 surface of insulating layer that flexible flat cuts the both ends of a cable is equipped with stiffening plate 3 at golden finger back to enhance interconnecting piece
The intensity of position.The conducting wire 2 of some or all of first conducting wire bending part A and the second conducting wire bending part B conducting wire 2 and parallel ends C
Between be equipped with angle.A cable is cut along flexible flat in part between the first conducting wire bending part A and the second conducting wire bending part B
Length direction cutting be that several conducting wires cut a 2a, every conducting wire cutting 2a includes several conducting wires 2, and conducting wire cuts a 2a
