Abstract
The utility model discloses a kind of double lacquered wire immediate frequency cable, comprise core and be coated on external insulation layer, screen, the restrictive coating outside core, screen is coated on outside external insulation layer, and restrictive coating is coated on outside screen; Core comprises inner core and outer core, inner core is formed around the heart yearn at a center is stranded by many heart yearns, outer core is formed by the even circumferential arrangement of many heart yearns around an imaginary circles, after heart yearn is stranded around the enamelled wire at a center by many enamelled wires, outsourcing insulation forms again, inner core is coated with interior wrapped film, and interior wrapped film is coated with inner insulating layer, and outer core is coated on outside inner insulating layer, outer core is coated with outer wrapped film, and external insulation layer is coated on outside outer wrapped film.The utility model not only increases the mechanical performance of cable, electric property and heat resistance, and utilizes skin effect, increases conductor ampacity, reduce electric current attenuation, thermal effect is lower, simultaneously, outer core and tin plated wire screen enhance shield effectiveness, decrease interference.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of double lacquered wire immediate frequency cable.
Background technology
Cable normally forms by several or several groups of wires (often organizing at least two) are stranded around center, the similar rope of its shape, simultaneously outer cover height insulating barrier.
Immediate frequency cable is exactly the cable for transmission intermediate frequency signal, is generally used for the signal of transmission 20KHz to 3000KHz frequency.The core of traditional immediate frequency cable is concentrated as a branch of; and adopt that many bare copper wires are stranded to be formed more; outside arranges insulating barrier, screen, protective layer etc.; the signal shielding function of this cable is not very strong; easily cause the mutual interference between cable transmission signal and other external signal in the exigent application of function of shielding, be difficult to reach desirable signal transmission effect.
Utility model content
The purpose of this utility model is just to provide a kind of double lacquered wire immediate frequency cable with extremely strong function of shielding to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of double lacquered wire immediate frequency cable, comprise core and be coated on external insulation layer, screen, the restrictive coating outside described core, described screen is coated on outside described external insulation layer, and described restrictive coating is coated on outside described screen; Described core comprises inner core and outer core, described inner core is formed around the heart yearn at a center is stranded by many heart yearns, described outer core is formed by the even circumferential arrangement of many heart yearns around an imaginary circles, after described heart yearn is stranded around the enamelled wire at a center by many enamelled wires, outsourcing insulation forms again, described inner core is coated with interior wrapped film, described interior wrapped film is coated with inner insulating layer, described outer core is coated on outside described inner insulating layer, described outer core is coated with outer wrapped film, and described external insulation layer is coated on outside described outer wrapped film.
As preferably, described enamelled wire is enamel covered wire, and after described heart yearn is stranded around the enamelled wire at a center by enamelled wire described in the six roots of sensation, wrapped in teflon insulating barrier forms again.
Described inner core is formed around the described heart yearn at a center is stranded by 18 described heart yearns, and described outer core to be arranged around the even circumferential of an imaginary circles by 19 described heart yearns and forms.
Described screen is tin plated wire screen.
Described inner insulating layer and described external insulation layer are PVC insulating barrier.
Described interior wrapped film and described outer wrapped film are poly tetrafluoroethylene.
The beneficial effects of the utility model are:
Many enamelled wires are twisted into heart yearn by the utility model, many heart yearns are twisted into inner core, many heart yearns are uniformly distributed in the skin of inner core, and wrapped film and insulating barrier are set between inner core and outer core, not only increase the mechanical performance of cable, electric property and heat resistance, and it is long-pending to increase cross-sectional area of conductor, utilize skin effect, increase conductor ampacity, reduce electric current attenuation, compare the cable that same cross-sectional is long-pending, its thermal effect is lower, simultaneously, outer core and tin plated wire screen play shielding action jointly, this double layer screen effect not only strengthens shield effectiveness, and make alternating current circuit to reduce interference.
Accompanying drawing explanation
Fig. 1 is the radial section structural representation of double lacquered wire immediate frequency cable described in the utility model;
Fig. 2 is the A-A cross section structure schematic diagram in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, double lacquered wire immediate frequency cable described in the utility model comprises core, described core comprises inner core and outer core, described inner core is formed around the heart yearn 2 at a center is stranded by 18 heart yearns 2, described outer core is formed by the even circumferential arrangement of 19 heart yearns 2 around an imaginary circles, after heart yearn 2 is stranded around the enamel covered wire 9 at a center by six roots of sensation enamel covered wire 9, wrapped in teflon insulating barrier 1 forms again, described inner core is coated with interior wrapped film 7, interior wrapped film 7 is coated with inner insulating layer 4, described outer core is coated on outside inner insulating layer 4, described outer core is coated with outer wrapped film 6, external insulation layer 5 is coated on outside outer wrapped film 6, tin plated wire screen 8 is coated on outside external insulation layer 5, restrictive coating 3 is coated on outside tin plated wire screen 8, inner insulating layer 4 and external insulation layer 5 are PVC insulating barrier, and interior wrapped film 7 and outer wrapped film 6 are poly tetrafluoroethylene.
As shown in Figure 1, 19 heart yearns that the transfer wire of double lacquered wire immediate frequency cable described in the utility model comprises inner core totally 19 × 7=133 root enamel covered wire and outer core 19 heart yearns totally 19 × 7=133 root enamel covered wire form, there is between inner core and outer core insulating properties and shielding, utilize skin effect, increase conductor ampacity, reduce electric current attenuation, compare the cable that same cross-sectional is long-pending, its thermal effect is lower, simultaneously, outer core and tin plated wire screen 8 play shielding action jointly, this double layer screen effect not only strengthens shield effectiveness, and make alternating current circuit to reduce interference.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
