Abstract
The utility model relates to a shielding cable, which comprises a metal core (1), an insulating layer (2), a shielding mesh (4) and an outer layer insulation sheath (5). The metal core (1) comprises an isolated hot wire L, a zero line N and a ground line G. The utility model is characterized in that a shielding film is fixed between the hot wire L of the metal core (1), the insulting layer (2) of zero line N and the shielding net (4). The metal core (1), the insulating layer (2), the shielding mesh (4) and the outer layer insulation sheath (5) are arranged from inside to outside. The utility model has the functions for shielding and anti-fire and is reliable and safe for application.
Description
Technical field
The utility model relates to cable, particularly relates to a kind of shielded type cable with shielding and anti-fire action that is used for household electrical appliance.
Background technology
Using various household electrical appliance in people's life, all household electrical appliance all need cable to come to provide power supply for electrical equipment as refrigerator, electric cooker, electric chafing dish and air-conditioning etc., so that electrical equipment can be worked normally.Traditional power line generally all is by the metal core and is coated on its outside insulating barrier and constitutes, and the power line of electrical equipment generally all exposes to the open air outside the housing of electrical equipment, lacks special safeguard measure such as shielding and fire prevention.When being damaged, just the electrical equipment user is formed huge potential safety hazard when the solid external factor of power line.
Summary of the invention
The utility model is intended to solve the safeguard protection problem of electrical equipment cable, and provides a kind of have shielding and fire-proof function, safe and reliable shielded type cable.
For achieving the above object, the utility model provides a kind of shielded type cable, this shielded type cable comprises metal core 1, insulating barrier 2, gauze screen 4 and outer layer insulation sheath 5, wherein metal core 1 is made of live wire L, zero line N and the ground wire G of mutually insulated, it is characterized in that, be provided with one deck shielded film 3 between the insulating barrier 2 of live wire L, the zero line N of core 1 and gauze screen 4, core 1, insulating barrier 2, shielded film 3, gauze screen 4, outer layer insulation sheath 5 set gradually from inside to outside.
Shielded film 3 is made by conducting metal, is preferably become by aluminium, copper, can be pressed into layer of plastic film on the shielded film.
This cable is circle or flat cable.
Insulating barrier 2 and insulating sleeve 5 are made by igelite.
Good effect of the present utility model is, it has effectively overcome existing electrical equipment and has failed to the breakage of the power line that is exposed to the electrical equipment outside, plays the defective that unsafe factor such as spark protects.Owing to be provided with shielding construction; therefore not only can play the effect of shielding interference signal; also the live wire that causes because of cable bad and the electric leakage signal of the zero line starting the arc can be transferred to the fire prevention leakage protecting plug that is connected with cable, thereby make the outage of fire prevention leakage protecting plug play the safeguard protection effect.
Description of drawings
Fig. 1 is a flat shielded type cable structural representation of the present utility model, and wherein, Figure 1A is the flat cable partial sectional view, and Figure 1B is the end view of Figure 1A.
Fig. 2 is a circular shielded type cable structural representation of the present utility model, and wherein, Fig. 2 A is the round cable partial sectional view, and Fig. 2 B is the end view of Fig. 2 A.
Embodiment
Consult Fig. 1, Fig. 2, shielded type cable of the present utility model comprises metal core 1, insulating barrier 2, gauze screen 4 and outer layer insulation sheath 5, shown in Figure 1A, Fig. 2 A, described metal core 1 is made of live wire L, zero line N and the ground wire G compenzine of mutually insulated, live wire, zero line and ground wire are made up of the copper wire twisted wire of AWG wire gauge, are the leading body parts of this shielded type cable.Described insulating barrier 2 is made by polychloroethylene insulation material, and it is coated on the outside of the compenzine of metal core, plays the safe insulation effect.Main points of the present utility model are, are provided with one deck shielded film 3 in insulating barrier 2 outsides of live wire L, the zero line N of core 1, and this shielded film 3 is made by conducting metal, and in this example, shielded film is an aluminum laminated films.Also can on metallic film, be provided with or be pressed into a kind of plastic film.Shielded film 3 can play the effect of shielding interference signal; be transferred to the fire prevention leakage protecting plug that is connected with cable with gauze screen in conjunction with the electric leakage signal that plays the solid cable bad live wire L and the zero line N starting the arc simultaneously, make fire prevention earth leakage protective insert the transmitting effect that plays electric leakage signal with screened film jointly.Be provided with igelite insulating sleeve 5 in gauze screen 4 outsides, play protective effect the whole piece cable.
Shown in Figure 1B, Fig. 2 B, the cross section of shielded type cable of the present utility model can be the circular or flat oval shape that is roughly.
Claims (7)
