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.
Example (b): please refer to fig. 1, the utility model provides a resistant frequent bending flat power cord, including three strand core 1 and two strands of packing strip 2, three strand core 1 is live wire, zero line and the ground wire of power cord respectively, and core 1 comprises the conductor and crowded package conductor insulation outside the conductor. Three strand sinle silk 1 and two strands of packing are parallel staggered arrangement, and three strand sinle silk 1 is outer to be crowded package jointly with two strands of packing 2 has around band layer 3, has insulating inner sheath layer 4 around band layer 3 outer crowded package, and insulating inner sheath layer 4 outer crowded package has armor 5, and armor 5 is woven by the double-deck knitting of steel wire braider by tinned soft attitude round copper line and forms, and 5 outer crowded packages of armor have insulating oversheath layer 6.
One end integrated into one piece that is close to sinle silk 1 on the filler strip 2 has arc concave 201, the one end integrated into one piece that is close to around band layer 3 on the filler strip 2 has straight face 202, dumbbell shape cavity 203 has been seted up to the center department of filler strip 2, the one end that is close to arc concave 201 in the dumbbell shape cavity 203 is equipped with and has first interior rib 204 with filler strip 2 integrated into one piece, and the one end that is close to straight face 202 in the dumbbell shape cavity 203 is equipped with and has interior rib 205 of second with filler strip 2 integrated into one piece. The thickness of the first inner rib 204 is smaller than that of the second inner rib 205, and the vertical cross section of the first inner rib 204 and the vertical cross section of the second inner rib 205 are rectangular.
Arc concave surface 201 and straight face 202 are used for filler strip 2 laminating sinle silk 1 and around band layer 3 respectively for the cable line structure is compact, regular. The dumbbell-shaped cavity 203 saves the material of the filler strip 2, provides deformation space for the compression or bending of the filler strip 2, and the power line is resistant to frequent bending integrally. After the filling bar 2 is compressed or bent to a certain degree, the first inner rib 204 and the second inner rib 205 are squeezed with each other, so as to limit the degree of compression or bending of the filling bar 2, that is, after the power line is compressed or bent, the filling bar 2 can maintain the regularity of the power line to a certain degree. When the power line is in a frequently bent environment, the filling strip 2 avoids the twisting of the folded wire core 1. The three-strand wire core 1 and the two-strand filling strip 2 are uniformly distributed and arranged, and have the advantages of small volume, tensile resistance, wear resistance, twisting resistance, bending resistance and rolling resistance.
Insulating oversheath layer 6 is crowded outward and is wrapped up with silica gel restrictive coating 7, and the outer fringe integrated into one piece of silica gel restrictive coating 7 has protection rib 8, and protection rib 8 is equidistant parallel distribution in the straight face end on silica gel restrictive coating 7. The vertical section of the protection rib 8 is rectangular, and the thickness of the protection rib 8 is not more than two millimeters. The existence of protection rib 8 makes the straight face end of silica gel restrictive coating 7 can not worn and torn by the transition, perhaps only when protection rib 8 is worn and torn the back, the straight face end of silica gel restrictive coating 7 just can be worn and torn, and the wearability of power cord is good.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
