Abstract
The utility model discloses a casing to protect electric circuit, comprising a hollow PVC casing and a copper braid arranged outside the PVC casing, wherein the inner wall of the PVC casing is coated with a nano-talcum powder layer. The utility model provides the casing to protect electric circuit, the inner wall of the PVC casing is coated with a nano-talcum powder layer and the outer wall of the PVC casing is provided with the copper braid, thereby having a good shielding effect, a simple production, a bending, acid, alkali, oil and salt resistant effects.
Description
Technical field
The utility model relates to the protective casing of cable, is specifically related to a kind of sleeve pipe that can protective device circuit.
Background technology
Along with the raising of people's living standard, the development of the communication technology, communication has become a requisite part in people's life.And cable as communication in an important transmission tie, the quality of cable directly has influence on the quality of communication quality.
And as an important indicator investigating communication quality, i.e. maintaining secrecy and definition of communication, depends on the anti-tampering ability of cable line to a great extent.In the market; in order to guarantee the shielding properties of cable line; mainly to adopt the skin at cable call wire that one shielding protection cover is set; but traditional this cable sleeve with function of shielding, its shielding properties and flexibility, bend-resistance and acid-alkali-resistant degree can not reach desirable effect simultaneously.
On the other hand; because all coordinating cable call wire, produces in advance by shielding protection cover; for core boundling is got up; the internal diameter of shielding protection cover can not be excessive; therefore but because cable call wire is many, caliber is relatively little, cable call wire is being worn in shielding protection cover time; operate extremely difficultly, cost cost of labor is high and efficiency is low.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide the PVC sleeve pipe that a kind of shield effectiveness is good, produce simple and bend-resistance, acid and alkali-resistance oil salt.
For achieving the above object; the utility model adopts following technical scheme: a kind of sleeve pipe that can protective device circuit; the copper braid that it comprises the PVC sleeve pipe of hollow structure and is located at PVC bushing outer surface, described PVC internal surface of sleeve pipe is coated with nanomete talc powder layer.
On the basis of such scheme, preferably, described PVC sleeve pipe is made by PVC material, also adds the particle of short glass fiber, silane coupling agent and aluminium hydroxide in wherein said PVC material.
On the basis of such scheme, preferably, its surface of described copper mesh grid is coated with one deck zinc.
On the basis of such scheme, preferably, described copper braid outer surface is also provided with PVC protective layer.
The beneficial effects of the utility model are:
Than prior art; a kind of sleeve pipe that can protective device circuit of the utility model; because PVC bushing outer surface is provided with copper braid, make it possess good electricity shielding, and be coated with nanomete talc powder layer at the inner surface of PVC sleeve pipe; thereby avoided threading process; can directly by Shooting Technique, at call wire, inject PVC layer outward, form PVC sleeve pipe, the trouble that can remove so on-the-spot sleeve pipe from; use manpower and material resources sparingly, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sleeve pipe that can protective device circuit of the utility model.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Refer to Fig. 1; a kind of sleeve pipe that can protective device circuit of the utility model; the copper braid 20 that it comprises the PVC sleeve pipe 10 of hollow structure and is located at PVC sleeve pipe 10 outer surfaces; described PVC sleeve pipe 10 coated inner wall have nanomete talc powder layer 40; wherein; this PVC sleeve pipe 10 is the particle formed by extrusion and tension that add short glass fiber, silane coupling agent and aluminium hydroxide in PVC material, to improve the characteristic such as shrinkage, anti-flammability, toughness, ageing resistance, bending resistance degree intensity of PVC sleeve pipe.
Be further used as the preferred version of this case, described copper mesh grid 20 its surfaces are coated with one deck zinc.
A kind of sleeve pipe that can protective device circuit of the present utility model, inner surface at PVC sleeve pipe 10 is provided with nanomete talc powder layer 40, make PVC sleeve pipe 10 and the combination of cable call wire directly by Shooting Technique, at call wire, to inject PVC layer outward, form PVC sleeve pipe 10, remove the trouble of on-the-spot sleeve pipe from, use manpower and material resources sparingly, increase work efficiency; Simultaneously; the zinc-plated copper mesh grid 20 of outer surface parcel one deck at PVC sleeve pipe 10; not only can effectively guarantee the antijamming capability of the sleeve pipe that the utility model can protective device circuit; strengthen its shield effectiveness; guarantee definition and the reliability of signal transmission; and the utility model can protective device circuit the whole toughness of sleeve pipe can increase substantially, there is good warping resistance effect.
On the basis of such scheme, preferably, in order further to guarantee the acid and alkali-resistance oil salt effect of the sleeve pipe that the utility model can protective device circuit, described copper braid 20 outer surfaces are also provided with PVC protective layer 30.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection range of the utility model claim within.
