Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a wire core; 2. an insulating layer; 3. a core bar; 4. a support plate; 401. embracing a claw; 402. an elastic abutting arm; 5. a buffer chamber; 6. a first shielding layer; 601. a first bar-shaped groove; 7. a second shielding layer; 8. a tegument layer; 801. a second strip-shaped groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a flat type signal line of bending resistance type as shown in fig. 1, including long banding backup pad 4, backup pad 4's both ends all are connected with the claw 401 of embracing that is used for the fixed core group of centre gripping, it is major arc structure and symmetric distribution to embrace claw 401, it extends elasticity butt arm 402 to embrace one section that claw 401 kept away from the free end along tangential direction, the free end of elasticity butt arm 402 extends to and turns over to the book after backup pad 4's the middle part and the butt embraces claw 401 on what its self was connected, and elasticity butt arm 402 and embrace and close cushion chamber 5 between the claw 401, two periphery claddings of embracing claw 401 have the sheath, and the elasticity is fixed with the core strip 3 that is used for the bending resistance between two elasticity butt arms 402 that correspond and the sheath, the plastic part that the core strip 3 optional bending radius is bigger than core group, core strip 3 made like the PP plastics. When buckling the use to the signal line, because the performance of the bending resistance that core strip 3 self has, the supplementary bend radius that has increased the signal line that sets up of core strip 3 reduces current signal line and causes the risk of damage easily because of too much buckling, and then has prolonged the life of signal line, simultaneously, when the signal line is more, can avoid causing the mixed and disorderly and wire winding scheduling problem of wiring, consequently still has the neat and artistic advantage of wiring. Through setting up the elasticity butt arm 402 that encloses to close buffer chamber 5, can provide the space that can the elastic bending warp for core strip 3 when core strip 3 buckles, reduce the risk that core strip 3 is to the hard butt of sheath and destroy.

In this embodiment, the clasping claw 401 and the elastic abutting arm 402 are made of TPE material.

It should be noted that the sheath includes a first shielding layer 6, a second shielding layer 7 and a tegument layer 8 which are sequentially arranged from inside to outside, and the core strip 3 is elastically fixed between the two corresponding elastic abutting arms 402 and the first shielding layer 6.

In addition, the two inner side walls of the first shielding layer 6, which are attached to the core strip 3, are uniformly provided with first strip-shaped grooves 601 along the length direction; the two outer side walls of the tegument layer 8 adjacent to the core strip 3 are uniformly provided with second strip-shaped grooves 801 along the length direction. Under the dual functions of heating and bending of the signal wire, the possibility that the sheath generates wrinkles due to bending and accelerates material oxidation and aging is reduced, and the service life of the signal wire is further prolonged.

Finally, the wire core group comprises a wire core 1 and a perfluoroethylene propylene copolymer insulating layer 2 wrapped outside the wire core 1.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
