Abstract
The utility model discloses a multi-functional domestic socket, comprising an isolated base, a cap plate, a socket hole, a voltage-sensitive resistor, an earthing strip, a connecting strip, etc. When the multi-functional domestic socket is used as the power socket of a household electric appliance, the multi-functional domestic socket can protect the household electric appliance from being damaged by the over voltage of a power. In addition, the socket can also be used as an antenna socket for a TV and has the safety action of lightning protection which does not belong to an ordinary antenna socket.
Description
The utility model 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 because supply line's accident of meeting accident causes the voltage rising.That is to say that existing socket can only provide power supply, but can not guarantee 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.
The purpose of this utility model is to provide a kind of novel multifunctional domestic socket, and it can make household electrical appliance power supply inserting easily, can prevent that again the contingent switching overvoltage of electric power system, abnormally high-voltage from causing damage to household electrical appliance.(in the three-phase and four-line electric power system commonly used at present, as long as zero main line loose contact, open circuit, arcing can cause that all 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.It will have lightning protection function this moment, and the damage to crops caused by thunder that the protection television set is not introduced by exterior aerial damages.
The utility model comprises insulation cover plate (13), insulator foot (12) and socket aperture, ground strip (1), brace (4), (5) and piezo-resistance (2) and (3), and socket aperture can be made of one or more groups as required.Now in conjunction with Fig. 2 Fig. 3 operation principle of the present utility model is described, (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 the earth connection screw that have fastening piezo-resistance to go between on the ground strip are generally made 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 the screwed hole of power supply wiring screw (6), (7) and fixed socket hole (A) and (B) on it.The utility model is when doing the supply socket use, and the power line of supply line is connected on power supply wiring screw (6) and (7), and in the plug insertion socket hole (A) and (B) of household electrical appliance, basically do not have electric current to flow through in two piezo-resistances this moment.But, flow through bigger electric current in the piezo-resistance immediately as long as unusual the rising appears in voltage.If just the big electric current that flows through in the piezo-resistance so of the switching overvoltage of the Millisecond fuse in the supply line that can not fuse only causes 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 cause that for a certain reason supply voltage time that raises unusually is 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 pulled out 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), still lightning current appears in (5), piezo-resistance (2) or (3) conducting immediately, making lightning current pass through ground strip (1) releases to the earth, because the discharge capacity 〉=1000A of the piezo-resistance that the utility model is selected for use, thunder and lightning under drawing for the domestic television set feeder line can 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 utility model is that it not only can be as the connector device of various household electrical appliance, and can also provides security protection to household electrical appliance compared with the prior art, makes it to exempt from the unexpected high pressure of supply line and 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.

Embodiment:
Make cover plate (13) base (12) with insulating material such as plastics or bakelites, on base with screw fastening 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.Another root lead-in wire of piezo-resistance (2) and (3) all is fastened on the ground strip (1) by screw, is separated with plastic insulation sheet (10) between two piezo-resistances.A screwed hole that has three holes being convenient to that mounting receptacle uses and securing cover plate to use on the base.Have on the cover plate to be suitable for the hole that plug inserts, and have the trade mark etc. of decoration function.Plate is made with latten(-tin).Socket aperture (A), (B) are bent into the elasticity phosphorus bronze sheet, and it is the same that its shape and at present common socket aperture bend shape.Only insert in order to be suitable for the garden plug, itself and plug contact portion are suppressed with a scrobicula trace, and this also is common in the prior art.(being convenient to antenna inserts with garden banana type plug).Ground strip (1) is made with latten(-tin).RM4-A-120-1000 type or RM4-A-150-1000 type Zinc-oxide piezoresistor that piezo-resistance is selected with process.
