Background
Nowadays, we have entered the internet era, and various weak current cables are widely used in various network wiring, such as wide area networks, enterprise local area networks, and home internal networks, and are connected by using a large amount of weak current cables. Common weak current cables mainly include optical fibers, network cables, coaxial cables and the like. They are characterized by low price and simple and convenient laying.
The common weak current cable is basically exposed in the common use process, except that electromagnetic interference exists among the cables and mainly damaged by environments such as oxidation, high temperature, severe cold, illumination, external force, chemical erosion and the like, the common weak current cable can be damaged by eating and eroding of organisms such as mice, termites and the like, so that the phenomena of line interruption, transmission attenuation and the like are caused, the network use is greatly influenced, and potential safety hazards exist.
Disclosure of Invention
The utility model aims to solve the technical problem that realize a light current cable, thereby this cable has higher barrier propterty through setting up protector.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a weak current cable with protector, the center of weak current cable is the sinle silk, the outer cladding of sinle silk has protector, protector by outer to interior cladding in proper order has inoxidizing coating, filling layer, insulating layer and contact layer, the filling layer includes flame retardant coating, shielding layer, protection against rodents layer, the flame retardant coating is the parcel layer of making by special fluorine dragon, the shielding layer is for overlapping the shielding protective layer around the package formation by the anaerobic copper wire, the protection against rodents layer is the parcel layer of making by glass fiber.
The protective layer is a wrapping layer made of polyurethane.
The insulating layer is a wrapping layer made of polyether polyurethane mixture.
The contact layer is a substrate-free 3M adhesive tape, and two sides of the 3M adhesive tape are coated with elastomer pressure-sensitive adhesive layers.
The fire-resistant layer in the filling layer is arranged on the innermost layer, the shielding layer is an intermediate layer, and the rat-proof layer is used as an outer layer.
The utility model discloses a set up the inoxidizing coating, make the weak current cable have higher barrier propterty, the environment-friendly material that protector polyurethane added superfine fiber and made has better tensile resistance, wearability, because the filler is the environment-friendly filler that polyethylene added fire retardant made, has better high temperature resistance and cold resistance; by arranging the rat-proof layer, the rat-proof effect is achieved due to the fact that organisms such as rats and the like repel the smell of the rat repellent, in addition, the rat-proof layer is made of novel glass fiber materials, and after the organisms such as rats bite the rat-proof layer, the finely crushed glass fibers give up biting; the shielding wire is added in the filling layer, so that the shielding effect of the weak current cable is improved, and the mutual electromagnetic interference among the weak current cables is avoided; through setting up the flame retardant coating, adopt non-temperature-absorbing material teflon to make the device flame retardant index improve, and be difficult for being blown by the naked light, strengthened the guard action to inside light current cable.
Drawings
The following brief descriptions of the contents expressed by each figure and the marks in the figures in the specification of the present invention are as follows:
FIG. 1 is a cross-sectional view of a low current cable;
the labels in the above figures are: 1-protective layer, 2-insulating layer, 3-contact layer, 4-filling layer, 5-fire-resistant layer, 6-shielding layer, 7-rat-proof layer and 8-shielding wire.
Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
As shown in fig. 1, the weak current cable sequentially comprises from outside to inside: a protective layer 1, an insulating layer 2 and a contact layer 3; inoxidizing coating 1 has functions such as fire resistance, wear-resisting, anti mouse are stung, and insulating layer 2 and contact layer 3 constitute the insulation core, set up filling layer 4 between inoxidizing coating 1 and the insulating layer 2, and filling layer 4 sets gradually flame retardant coating 5, shielding layer 6, protection against rodents layer 7 from inside to outside.
Each layer structure is explained in detail below:
the protective layer 1 is an environment-friendly material prepared by adding polyurethane into superfine fiber, and the polyurethane and the superfine fiber have better tensile property and wear resistance and can play a better external protection role;
the insulating layer 2 is a polyether polyurethane mixture insulating layer 2;
the contact layer 3 is a base material-free adhesive tape coated with an elastomer type pressure-sensitive adhesive, and two sides of the 3M adhesive tape are coated with elastomer type pressure-sensitive adhesive layers, so that the base material-free adhesive tape is adhered to the weak current cable, and meanwhile, the outside of the protective layer 1 can be reinforced by using auxiliary materials such as a cable tie, a magic tape and the like, so that the protective device is prevented from aging and falling off;
the whole filling layer 4 can be an environment-friendly filling material prepared by adding flame retardant into polyethylene, wherein a shielding wire 8 is arranged, and the filling layer has better high-temperature resistance and cold resistance. The preferred scheme can be formed by combining a fire-resistant layer 5, a shielding layer 6 and a rat-proof layer 7;
