Description

A kind of shielding line

Technical field

This utility model relates to shielding line technical field, is specially a kind of shielding line。

Background technology

Signal conductor is primarily referred to as in electric control circuit for transmitting the circuit of heat transfer agent and the information of control, holding wire is often configured to a branch of or multi beam transmission line with a plurality of cable, the holding wire of different purposes often has different industry standards, in order to standardization produces and application。

In the use procedure of signal conductor, in order to avoid interference signal to signal conductor and the loss reducing transmission signal, people can at one layer of conductive fabric of arranged outside of signal conductor, braiding copper mesh or Copper Foil as screen layer, for shielded signal, shielding line thus produces, but the fire resistance of existing shielding line, corrosion resistance and electrical insulating property are all poor, therefore shielding line is very easy to damage, service life is short, and the easily electric leakage of electrical insulating property difference, safety is low。

Utility model content

The purpose of this utility model is in that to provide a kind of shielding line, with the problem solving to propose in above-mentioned background technology。

For achieving the above object, this utility model provides following technical scheme: a kind of shielding line, including: transfer wire, F46 dielectric isolation layer, screen layer, basalt fibre protective layer, PVC protects set, described transfer wire is wrapped in F46 dielectric isolation layer, fixed one layer of screen layer on the outer circumference surface of described F46 dielectric isolation layer, described screen layer adopts copper mesh or Copper Foil to make, fixed one layer of basalt fibre protective layer on the outer circumference surface of described screen layer, described basalt fibre protective layer adopts basalt fibre plain to make, fixed one layer of PVC protection set on the outer circumference surface of described basalt fibre protective layer, described PVC protection set adopts PVC to make。

As preferably, described PVC protection puts and is cased with multiple magnet ring。

As preferably, the quantity of described transfer wire is at least one。

As preferably, the filament diameter of the basalt fibre of described basalt fibre protective layer is 8 μm-16 μm。

Compared with prior art, the beneficial effects of the utility model are: have characteristic high temperature resistant, corrosion resistant, long service life, have the electrical insulating property of excellence simultaneously, and security performance is high, and the shielding properties of interference signal is higher。

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。

Refer to Fig. 1, this utility model provides following technical scheme: a kind of shielding line, including: transfer wire 1, F46 dielectric isolation layer 2, screen layer 3, basalt fibre protective layer 4, PVC protects set 5, described transfer wire 1 is wrapped in F46 dielectric isolation layer 2, fixed one layer of screen layer 3 on the outer circumference surface of described F46 dielectric isolation layer 2, described screen layer 3 adopts copper mesh or Copper Foil to make, fixed one layer of basalt fibre protective layer 5 on the outer circumference surface of described screen layer 4, described basalt fibre protective layer 5 adopts basalt fibre plain to make, on the outer circumference surface of described basalt fibre protective layer 5, fixed one layer of PVC protects set 5, described PVC protection set 5 employing PVC makes。

As preferably, described PVC protection set 5 being cased with multiple magnet ring 6。

As preferably, the quantity of described transfer wire 1 is at least one。

As preferably, the filament diameter of the basalt fibre of described basalt fibre protective layer 5 is 8 μm-16 μm。

This utility model is implemented: transfer wire 1 is for the transmission of signal, F46 has good electrical insulation capability and resistance to elevated temperatures, therefore by using the F46 F46 dielectric isolation layer 2 made to wrap up transfer wire 1, good electric insulation effect and resistance to elevated temperatures can be played, screen layer 3 is then for the shielding to interference signal, due to basalt fibre not only good stability, but also there is electrical insulating property, anticorrosive, flame resistant, high temperature resistant multiple excellent properties, therefore the basalt fibre protective layer 4 that basalt fibre plain is made is adopted can to further function as good electric insulation effect relative to F46 dielectric isolation layer 2, corrosion-resisting function and fire-retardant effect, not only not easily there is the phenomenon of electric leakage in shielding line so described in the utility model, security performance is high, and long service life, it is hardly damaged, set 5 is protected additionally by arranging one layer of PVC outside basalt fibre protective layer 4, the stability of PVC is relatively good, therefore as outermost layer, integrated support and the effect of protection can be played, and by arranging multiple magnet ring 6 on PVC protection set 5, under the effect of magnet ring 6, while making normally useful signal well pass through, passing through of high-frequency interferencing signal can be suppressed, such magnet ring 6 further functions as the effect of shielding interference signal relative to screen layer 3, therefore shield effectiveness is relatively good, it is suitable for promoting the use of。

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof。
