Description

The fixing multi-functional safety socket of mobile lockable

Affiliated technical field:

The utility model is fixed the multi-functional safety socket of mobile lockable, relates to a kind of electrical outlets that family uses.

The household electrical appliance socket that uses comprises insulator foot and insulation cover plate at present, and one group or array socket aperture.Can make and patch usefulness between household electrical appliance and the supply line easily, to provide its work required AC power.But, if, generally all do not have corresponding safeguard procedures, that is to say that existing socket can only provide power supply because supply line's accident of meeting accident causes the electricity rising, but can not protect the safety of supply voltage for household electrical appliance.In addition, general socket also should not be done the use of TV set aerial socket.

Summary of the invention:

The purpose of this utility model is to provide a kind of novel multi-functional safety socket of fixing mobile lockable.It can make household electrical appliance power supply inserting easily, can prevent the contingent switching overvoltage of electric power system again, and abnormally high-voltage causes damage to household electrical appliance.(in the three-phase and four-line electric power system commonly used at present) as long as the zero line loose contact opens a way, draws Gu Douhui to cause that wherein certain phase voltage in the three-phase imbalance raises unusually.In addition, the utility model can also be as the antenna socket of television set external connection antenna, and it will have lightning protection function this moment, and the thunder that the protection television set is not introduced by exterior aerial damages.

The utility model comprises insulator foot (10), ground strip (1), brace (4), (5) and piezo-resistance (2) and (3).Socket aperture can be made of one or more groups as required.(2), (3) are two piezo-resistances among the figure, and (piezo-resistance has polytype available, generally selects Zinc-oxide piezoresistor here for use.) these two piezo-resistances are by ground strip (1) series connection, (screw and earth connection screw that fastening piezo-resistance lead-in wire is arranged on the ground strip, generally make with latten(-tin)) other two lead-in wires of piezo-resistance are fixed on the terminal screw (8) and (9) of brace (4), (5).Brace is generally also made with latten(-tin), also has power supply wiring screw (6), (7) and fixed socket hole (A) and screwed hole (B) on it.The utility model is when doing the supply socket use, the power line of supply line is connected on power supply wiring screw (6) and (7), household electrical appliance socket aperture (A) and (B) in, basically do not have electric current to flow through in two piezo-resistances this moment, but as long as unusual the rising appears in voltage, piezo-resistance flows through bigger electric current immediately, if the big electric current that flows through in the piezo-resistance so of the switching overvoltage of the Millisecond fuse in the electric line that can not fuse just, only cause the moment pressure drop on the line, that is to say that piezo-resistance can absorb this of short duration switching overvoltage.Prevent that the household electrical appliance insulation from sustaining damage.If the supply voltage that causes for a certain reason raises unusually the time longer, will flow through bigger electric current in the piezo-resistance, make that the fuse in the supply line fuses immediately, protected the safety of household electrical appliance.If the utility model is as tv antenna socket, just should connect the reliable ground line in ground strip (1).(terminal screw (6) and (7) need not) socket aperture (A) and (B) respectively insert feeder plug and television set input plug.(the time spent can not dial except that the television set input plug.) like this, the utility model can be made lighting protection to the thunder and lightning that the television set external connection antenna may be introduced, draw following time as the thunder and lightning line feeder line of following the mandate of heaven, no matter be brace (4), or lightning current appears in (5), piezo-resistance (2) or (3) conducting immediately make lightning current pass through ground strip (1) and release to the earth.Because piezo-resistance discharge capacity 〉=1000A of selecting for use of the utility model, the thunder and lightning under drawing for the domestic television set feeder line can be gone and effectively be released.Thereby make television set exempt from loss, (feeder also can directly be fixed on terminal screw (6) and (7) without plug.)

The beneficial effects of the utility model are: the utility model compared with the prior art, be that it not only can be as the connector device of various electrical equipment, and can also provide security protection to household electrical appliance, the unexpected high pressure that makes it to exempt from supply line causes damage, because household electrical appliance all are parallel circuitss, as long as used a this multi-function jack, just can provide protective action to the whole electrical equipment below the whole shunt fuse, in addition, the utility model also can be used as the television set external connection antenna socket, has the lighting protection effect that general antenna socket does not have.

Description of drawings:

Embodiment:

Go up at base (10) and to have fastened two brace (4), (5) that have jack (A), (B), the screw (9) of a lead-in wire of the screw (8) of a lead-in wire of power supply wiring screw (6), (7) and fastening piezo-resistance (2) and fastening piezo-resistance (3) is arranged on the brace with screw.Last brace is generally also made with latten(-tin), also has the screwed hole of power supply wiring screw (6), (7) and fixed socket hole (A), (B) on it.

Claims (2)

1, a kind of fixing multi-functional safety socket of mobile lockable, it is by insulator foot and socket aperture, ground strip, brace and piezo-resistance are formed, it is characterized in that: piezo-resistance is made up of two Zinc-oxide piezoresistors, resistance is by earth connection sheet (1) series connection, other two lead-in wires of piezo-resistance are fixed on brace, on the terminal screw (8) and (9) of (4), (5).

2, the fixing multi-functional safety socket of mobile lockable according to claim 1, it is characterized in that: ground strip is made with latten(-tin), also has the screwed hole of power supply wiring screw (6), (7) and fixed socket hole (A), (B) on it.
