Abstract
The utility model provides a switch type household electric appliance protective plug, which is suitable for a household electric appliance to be connected with a conductor wire of a power supply and has the protective function. The switch type household electric appliance protective plug is formed by that a double-break switch 1 connected with a live wire 8 and a zero line 9 is arranged on a plug body 2 of a power plug. When the household electrical appliance is paused to use for a short time, the plug is not required to be pulled out, and the live wire and the zero line can be cut off simultaneously by turning off the double-break switch 1; thus, the power utilization loss caused by current entering, the aging of components in the household electric appliances, reduction of service life, and the accidents such as the burnout of the electric appliances, etc., are completely avoided. The switch type household electric appliance protective plug which has the advantages of simple structure and easy production is suitable for being matched with various household electrical appliances and office equipment.
Description
The utility model relates to a kind of switching regulator household electrical appliance protection plug, is the plug that is applicable to household electrical appliance connection power lead and has protective effect concurrently.
The power lead of household electrical appliance connection at present all uses common double-contact plug or three-pin plug.For avoid when of short duration when inactive because power supply is failed to disconnect fully in the usefulness electrical loss that taken place, the household electrical appliance accidents such as component aging, reduction of service life and electrical equipment burn, all need to pull out attaching plug usually, plug-in mounting again again during use.Thereby brought and used and the plug-in mounting when inactive and the trouble of pulling out plug, and the frequent plug of accumulating over a long period often causes the plug haptic element inclined to one side twisting strain that weares and teares, and often causes installing not firm, loose contact rings the electrical equipment result of use.And on the household electrical appliance original-pack plug good looking appearance to construct solid Replacement and Repair very bothersome.Also have and adopt the porous plug housing that has switch that is provided on the market to carry out the plug-in mounting connection; but the keying of its switch will force on the plug housing using of all electrical equipment of connecting respectively in each pin hole and stop must the synchronous fully consistent inconvenience that causes; sometimes still having electric current to feed in the electrical equipment after its open-close on-off is failed to be connected on the live wire so that caused and closes causes its components and parts lost of life or other contingencies occur, can not play the effect of protection electrical equipment fully.
The purpose of this utility model provides a kind of switching regulator household electrical appliance protection plug; it can be used on the household electrical appliance to connect power supply and double-break switch is housed on plug body; when the of short duration Shi Buxu of stopping using of household electrical appliance pulls out the plug of connection and can cut off live wire and the zero line that connects power supply simultaneously, avoid entering of electric current fully.
The utility model provides a kind of switching regulator household electrical appliance protection plug; be the plug that is applicable to household electrical appliance connection power lead and has protective effect concurrently, it is characterized in that it is formed by the double-break switch ［ 1 ］ that is connected to live wire ［ 8 ］ and zero line ［ 9 ］ is installed on the plug body ［ 2 ］ of attaching plug.The firewire contact ［ 14 ］ that its double-break switch ［ 1 ］ wherein connects live wire ［ 8 ］ for the firewire binding post ［ 7 ］ on the plug body ［ 2 ］, recline for common paired contact for the zero line binding post ［ 9 ］ on the plug body ［ 2 ］ with the zero line contact ［ 11 ］ that wherein is connected zero line ［ 9 ］ and the disconnection of common Cheng Shuan breaks away from.The earth terminal ［ 12 ］ that is connected with ground wire ［ 13 ］ can be installed in its plug body ［ 2 ］, be connected have on the earth terminal ［ 12 ］ stretch out on plug body ［ 2 ］ outer surface level with live wire haptic element ［ 5 ］ zero line haptic element ［ 4 ］ keeping parallelism and be the ground wire haptic element ［ 6 ］ of triangle tripartite confrontation position.
The utility model compared with prior art, it can exempt household electrical appliance using and the plug-in mounting and the trouble of pulling out the power lead plug when inactive, makes plug and connector assembly be connected firmly all the time to remain on and contacts good state.And double-break switch can be closed when inactive so that live wire in the power lead and zero line all disconnect simultaneously when electrical equipment is of short duration, really reach and break off electric current fully and enter.Accomplish to pull out plug and can play the same purpose that original needs pull out plug, can avoid burning and accident such as error shock with electrical loss, component aging, electrical equipment.It can also be installed on the plug housing as the plug housing lid and cause electric shock to avoid the tiny finger of children and stretch in the pin hole.

Parts title in the figure:
1, double-break switch 2, plug body 3, terminal cover 4, zero line haptic element 5, live wire haptic element 6, ground wire haptic element 7, firewire binding post 8, live wire 9, zero line 10, zero line binding post 11, zero line contact 12, earth terminal 13, ground wire 14, firewire contact
Embodiment: the plug body that constitutes by bayonet cap and connector assembly ［ 2 ］ as shown in Figure 1, its plug body ［ 2 ］ one sides have terminal cover ［ 3 ］, general double-contact plug all is fixed with firewire binding post ［ 7 ］ and zero line binding post ［ 10 ］ in plug body ［ 2 ］, they respectively be fixed on the outer side plane of plug body ［ 2 ］ on the live wire haptic element ［ 5 ］ that is parallel to each other be connected with zero line haptic element ［ 4 ］.The earth terminal ［ 12 ］ that has also installed connection ground wire ［ 13 ］ and ground wire haptic element ［ 6 ］ for some electrical equipment that is connected with ground wire additional is to form three-pin plug.A double-break switch ［ 1 ］ is installed on plug body ［ 2 ］ top as shown in Figure 2, in double-break switch ［ 1 ］, is provided with firewire contact ［ 14 ］ that is connected with live wire ［ 8 ］ and the zero line contact ［ 11 ］ that is connected with zero line ［ 9 ］.When double-break switch ［ 1 ］ breakdown or when closing its firewire contact ［ 14 ］ for firewire binding post ［ 7 ］, zero line contact ［ 11 ］ for zero line binding post ［ 10 ］ jointly paired contact recline or the disconnection of common Cheng Shuan breaks away from.Double-break switch ［ 1 ］ also can rest on above-mentioned contact respectively and reclines or disconnect on the disengaging configuration, can be in breakdown or closed condition for a long time with the use that adapts to electrical equipment or inactive needs.This kind double-break switch ［ 1 ］ can use the snapper formula switch of the two group of band switch contacts or adopt the slider formula switch of belt switch contact, both sides, but also other easy patterns of specialized designs so that match with attaching plug.This kind protection plug configuration is simple, production is easy, be fit to various household electrical appliance and the supporting use of office equipment.
