Abstract
A high-voltage anti-eddy cable clamp comprises a U-shaped base fixed bracket and a single connection component which is fixed on the U-shaped base fixed bracket and consists of a semicircular-ring-shaped single connecting body and a semicircular-ring-shaped gland, wherein the single connecting body is fixed on the U-shaped base fixed bracket through a bolt; one end of the gland is connected onto a rotating shaft at one end of the single connecting body; the gland rotates around the rotating shaft; the other end of the gland is connected with the other end of the single connecting body through a screw to form a circular ring; an electric cable is clamped in the circular ring; and inner wall surrounding materials of the single connecting body and the gland adopt polycarbonate or a blend of polycarbonate and ABS (acrylonitrile-butadiene-styrene) resin. According to the high-voltage anti-eddy cable clamp, an upper clamp and a lower clamp can rotate relatively, the upper clamp and the lower clamp adopt a composite material, and other parts adopt a metal material, so that the service life is prolonged; and the clamp is good in flame resistance, high in strength and long in service life, reduces the electricity cost, solves the problem of rigidity fixation of the electric cable, and can prevent displacement and jumping of the electric cable caused by the generation of an electrical force.
Description
Technical field
The invention belongs to the cable cleat technical field, particularly a kind of high pressure is prevented the eddy current cable cleat.
Background technique
Cable cleat is used for fixing cable, used cable cleat material generally is divided into metal and composite material in China's engineering at present, connect by screw between the folder up and down, with the time need to press from both sides fully up and down and separate, after being clipped on the cable, the screw that will press from both sides two ends more up and down all connects, and has brought inconvenience to use.In addition, the anchor clamps intensity height of metallic material, long service life, but shortcoming is to produce eddy current to cable.Direct current cables can produce eddy current, cannot use metal clip so exchange the single file cable.When adopting metallic material, fixed by cable, can produce high-tension current because cable is in operation, around core, produce closed magnetic circuit, thereby produce eddy current, eddy current be created in train by the time can make cable produce the heating phenomenon, influenced the working life of cable; And metallic material can cause scuffing to cable, can not effectively solve the generation of vortex phenomenon, thereby has reduced the working life of cable and the normal operation of train, has reduced electric energy loss.And the anchor clamps that composite material is made in use can not produce vortex phenomenon.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of high pressure to prevent the eddy current cable cleat, can rotate between the folder up and down, the screw that one side only need be installed in the time of fixedly gets final product, and adopt poly-carbon PC material, can effectively eliminate closed magnetic field, eliminated vortex phenomenon.
To achieve these goals, the technical solution used in the present invention is:
A kind of high pressure is prevented the eddy current cable cleat, comprise U type base fixing frame 1 and the single disjunctor assembly that is fixed on the U type base fixing frame 1, described single disjunctor assembly comprises the gland that singly connects body 2 and semi-round ring shape 3 of semi-round ring shape, singly connect body 2 by bolt on U type base fixing frame 1, one end of gland 3 is connected in the rotating shaft 4 that singly connects body 2 one ends, gland 3 rotates around this rotating shaft 4, the in addition end of gland 3 with singly connect body 2 and hold in addition and be connected by screw, constitute an annulus, cable promptly is clipped in this annulus.
The ring inner-wall material that singly connects body 2 and gland 3 of the present invention all adopts polycarbonate (PC), and molecular formula is (C
15H
16O
2CH
2O
3) n, n represents the degree of polymerization.Or the blend of employing polycarbonate (PC) and ABS resin, the blend mass ratio is 1:0.2-0.4.
Compared with prior art, can rotate between the present invention is pressed from both sides up and down, and folder adopts poly-carbon PC material and remaining part still adopts metallic material up and down, at last anticorrosion special processing is carried out on the surface, has improved working life.This anchor clamps flame retardant property is good, intensity is high, and long service life has reduced the transmission of electricity cost, has solved the rigidity fixation problem of cable, can prevent cable because displacement and the jumping phenomena that electrodynamic generation takes place.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Describe embodiments of the present invention in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of high pressure of the present invention is prevented the eddy current cable cleat, comprise U type base fixing frame 1 and the single disjunctor assembly that is fixed on the U type base fixing frame 1, described single disjunctor assembly comprises the gland that singly connects body 2 and semi-round ring shape 3 of semi-round ring shape, singly connect body 2 by bolt on U type base fixing frame 1, one end of gland 3 is connected in the rotating shaft 4 that singly connects body 2 one ends, gland 3 rotates around this rotating shaft 4, the in addition end of gland 3 with singly connect body 2 and hold in addition and be connected by screw, constitute an annulus, cable promptly is clipped in this annulus.
Gland 3 with singly connect body 2 usefulness screws and be connected up, with pin and rotating shaft 4 below couple together, formed single disjunctor assembly, gland 3 is as last folder, singly connect body 2 as pressing from both sides down, single disjunctor assembly is fixed on screw and has just constituted the anti-eddy current cable cleat of high pressure on the U type base fixing frame 1.
More preferably, the ring inner-wall material that singly connects body 2 and gland 3 of the present invention all adopts polycarbonate (PC), and molecular formula is (C
15H
16O
2CH
2O
3) n, n represents the degree of polymerization.Structural formula can be expressed as:
Polycarbonate (PC) is the general name that contains a family macromolecule compound of carbonic ester in molecular chain.It is a kind of novel thermoplastic, and transparency reaches 90%, is described as transparent metal.Firm and flexible has high impact properties, the dimensional stability and the very wide serviceability temperature of scope of height, good insulation performance and heat resistance and avirulent.
The present invention singly the ring inner-wall material of body 2 and gland 3 also can to adopt mass ratio be polycarbonate (PC) and the ABS resin blend of 1:0.2-0.4, high mechanical properties of its existing polycarbonate resin and heat resistance, have the good fluidity of ABS again, be convenient to machining characteristics.
Material can adopt the screw-type injection machine injection moulding.Barrel temperature: 250～320 ℃, injection pressure: 50～80MPa, die temperature: 85～120 ℃, screw speed: 40～60 times/min, finished product heat treatment: in 100～105 ℃ baking oven, toasted 10 minutes earlier, toasted again 30 minutes at 120～125 ℃ then, naturally cool to normal temperature and get final product.
Therefore, the present invention adopts the composite material of part allow singly to connect body 2 and gland 3 can effectively be eliminated closed magnetic field, thereby has prevented the phenomenon that eddy current forms, and remaining part still adopts metallic material, at last anticorrosion special processing is carried out on the surface, has improved working life.This anchor clamps flame retardant property is good, intensity is high, and long service life has reduced the transmission of electricity cost, has solved the rigidity fixation problem of cable, can prevent cable because displacement and the jumping phenomena that electrodynamic generation takes place is the ideal substitute of traditional cable anchor clamps.
