Abstract
The invention discloses a communication cable which comprises two copper wires which are spirally and tightly combined together, wherein the distance between the centers of the two copper wires is kept consistent at any point of the communication cable within the length scope, protecting jackets wrap the copper wires, and each protecting jacket comprises an upper protecting jacket and a lower protecting jacket which are clamped with each other. The communication cable adopts a twist-pair structure, so the stable impedance can be maintained, the self and outside interferences are effectively inhibited, the transmission frequency is high, meanwhile, the protecting jackets wrap the copper wires, so the cable is strongly protected, the protecting sleeves are clamped through folded edges, the combination is very firm, and the installation and maintenance are convenient.
Description
Technical field
The present invention relates to field of mobile communication, particularly relate to a kind of communications cable.
Background technology
The communications cable of the prior art adopts the separate type double structure to come transmission signals more, and such structure causes impedance unstable easily, and the external electromagnetic wave interference is excessive, makes transmission frequency low.And because the communications cable of prior art does not have self pulling force, and installation needs auxiliary appliance, built on stilts back wire rod is not firm, and instability is damaged easily, has potential safety hazard, wastes time and energy during maintenance, and useful life is shorter.
Summary of the invention
The technical problem that the present invention mainly solves provide a kind of solid and reliable, transmission frequency is high, long service life, the communications cable easy to maintenance.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of communications cable is provided; Comprise two shape copper cash of combining closely in the shape of a spiral, said two copper cash centre-to-centre spacing all are consistent any point in the length range of the communications cable, and said copper cash is coated with protective sleeve; Said protective sleeve comprises that protective sleeve reaches protective sleeve down, said upward protective sleeve and following protective sleeve clamping.
In preferred embodiment of the present invention, also be provided with the load-bearing line in the said communications cable, said load-bearing line combines with copper cash vertically.
In preferred embodiment of the present invention, said load-bearing line surface is coated with zinc.
In preferred embodiment of the present invention, said upward protective sleeve, following protective sleeve both sides are respectively arranged with flange, and said flange is the flange that cross sectional shape can plug together mutually.
In preferred embodiment of the present invention, the upper overturning on the said upward protective sleeve is to horizontal bending upwards bending again.
In preferred embodiment of the present invention, the following flange on the said protective sleeve down is the upwards last bending downwards of the horizontal again bending of bending earlier.
The invention has the beneficial effects as follows: the communications cable of the present invention can keep the stable of impedance owing to adopt twisted pair construction, effectively suppresses self and extraneous interference; Transmission frequency is high, simultaneously, because copper cash is coated with protective sleeve; Cable there is very strong protective capability; Rely on the flange clamping between the protective sleeve, firm in conjunction with very, convenient for installation and maintenance.
Description of drawings
Fig. 1 is the perspective view of the communications cable one preferred embodiment of the present invention;
Fig. 2 is the structural representation of the protective sleeve of the communications cable of the present invention;
The mark of each parts is following in the accompanying drawing: 1, copper cash, 2, go up protective sleeve, 3, protective sleeve down, 4, the load-bearing line, 5, flange, 6, upper overturning, 7, flange down.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1, the embodiment of the invention comprises:
A kind of communications cable; Comprise two shape copper cash 1 of combining closely in the shape of a spiral; Said two copper cash, 1 centre-to-centre spacing all is consistent any point in the length range of the communications cable; Said copper cash 1 is coated with protective sleeve, and said protective sleeve comprises that protective sleeve 2 reaches protective sleeve 3 down, said upward protective sleeve 2 and following protective sleeve 3 clampings.
Also be provided with load-bearing line 4 in the said communications cable, said load-bearing line 4 combines with copper cash 1 vertically, makes the communications cable need not after built on stilts also can keep the firm of self structure by outside plant.
Said load-bearing line 4 surfaces are coated with zinc, can improve its resistant to rust ability, have increased useful life.
As shown in Figure 2, said upward protective sleeve 2, following protective sleeve 3 both sides are respectively arranged with flange 5, the flange that said flange 5 can plug together mutually for cross sectional shape.Upper overturning 6 on the said upward protective sleeve 2 is to horizontal bending upwards bending again; Following flange 7 on the said protective sleeve 3 down is the upwards last bending downwards of the horizontal again bending of bending earlier; Make that through this structure flange 7 can be good at being plugged in the upper overturning 6 sound construction, easy installation and removal down.
Compared with prior art, the communications cable of the present invention can keep the stable of impedance owing to adopt twisted pair construction; Effectively suppress self and extraneous interference, transmission frequency is high, simultaneously; Because copper cash 1 is coated with protective sleeve, and cable is had very strong protective capability, rely on the flange clamping between the protective sleeve; Firm in conjunction with very, convenient for installation and maintenance.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
