Abstract

The utility model discloses a direct-buried direct-laying wire device. An insulating layer (3) is coated outside an ordinary conductive metal wire core (1) and an insulating layer (2). A soft metal protective layer (4) having the safe voltage is arranged outside the insulation layer (3), and a fire retardant insulating protective layer (5) is arranged at the most outer layer. The output terminal of a low-voltage safety power supply (6) is connected with the protective layer (4) through a protective coupling switch (7), and a main operating power supply outputs through the protective coupling switch (7). The utility model has the advantages of convenient and rapid burying and laying construction, low construction cost, material saving, little damage to building walls, safe use, long service life, etc.

Description

Direct-burried direct application type wire device

The utility model relates to a kind of direct-burried direct application type wire device that is used for indoor low tension power supply.

At present; in room lighting below China's 1 kilovoltage or the power power supply distribution engineering; utilize electric wire of the prior art secretly to bury to lay or furred ceiling in when laying; consider from the angle of Electrical Safety; generally do not allow electric wire is carried out direct-burried or straight applying; but the method that penetrates electric wire behind the first pipe arrangements such as employing steel pipe or plastic tube is again constructed; like this when the charged use of electric wire; because electric wire has the protection of steel pipe or plastic tube, just can prevent from miss the accident generation that electric shock takes place when hammering into nail or other conduction apparatus within the walls because of knowing to manage within the walls live wire.Yet the shortcoming of this laying wires method is that construction is complicated, the expense of taking a lot of work material, and cost is high.

The purpose of this utility model is: but a kind of wire device of safe direct-burried direct application type easy to use is provided.

The utility model is to constitute like this: it comprises common conducting metal core (1) and insulating barrier (2); outside insulating barrier (2), also wrap up a layer insulating (3); the ductile metal protective layer (4) that one deck band safe voltage is arranged outside insulating barrier (3); outside the ductile metal protective layer (4) of band safe voltage, one deck insulating protective layer (5) is arranged; the output of low-voltage safety power supply (6) is connected with protective layer (4) by protection coupled switch (7), and the work main power source is by protection coupled switch (7) output.

Owing to adopted technique scheme; during use; the utility model directly can be imbedded within the walls; and a low-voltage safety power supply (6) is communicated with the ductile metal protective layer; form the ductile metal protective layer (4) of band safe voltage; under normal circumstances this coat of metal has certain safe voltage; but do not form path; when electric wire is damaged; safety power supply on the protective layer forms path by human body and the earth; thereby protection coupled switch (7) starts and the work of disconnection main power source, thereby prevents to get an electric shock.The utility model is compared with existing electric wire, has easy construction, rapidly, cheap, the economical with materials of operating expenses, and to the construction wall damage advantages such as little, safe in utilization and long service life.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the schematic perspective view of the utility model electric wire.

Embodiment of the present utility model: when making, generally the utility model can be made into triple core wire or two core electric wires; conducting metal core (1) can adopt copper or aluminum to make; insulating barrier (2); (3) can adopt polyvinyl chloride or rubber insulation material to make; insulating protective layer (5) adopts the flame-proof polyvinyl chloride material; charged ductile metal protective layer (4) can adopt net metal silk or metal film to make; metal core (1) is wrapped fully with insulating barrier (2); and outside insulating barrier (2), wrap up a layer insulating (3) again; outside insulating barrier (3), make the charged ductile metal protective layer (4) of one deck; outside charged ductile metal protective layer (4), wrap one deck insulating protective layer (5) again; the output of low-voltage safety power supply (6) is connected by the ductile metal protective layer (4) of protection coupled switch (7) with the band safe voltage, and the main power source of will working gets final product by protection coupled switch (7) output.

Claims

1; a kind of direct-burried direct application type wire device; it comprises metal core (1); insulating barrier (2); metal core (1) is insulated layer (2) and wraps fully; it is characterized in that: outside insulating barrier (2), also wrap up a layer insulating (3); the ductile metal protective layer (4) that one deck band safe voltage is arranged outside insulating barrier (3); outside the ductile metal protective layer (4) of band safe voltage, one deck insulating protective layer (5) is arranged; low-voltage safety power supply (6) output is connected by the ductile metal protective layer (4) of protection coupled switch (7) with the band safe voltage, and the work main power source is by protection coupled switch (7) output.
