Abstract
The utility model relates to a protective socket with lightning protection, high voltage protection, and high current protection. A fuse box RD is connected between the lead wire of a power supply thereof and a contact point, and a voltage-sensitive resistor are connected between two contact points. The circuit and the socket body are arranged to form a body. When an electric network generates accidents in virtue of high voltage or high current, a voltage-sensitive resistor is in short circuit and the fuse box is damaged for playing the protecting action for electric appliances. The protective socket has the advantages of low cost, easy repair, and easy replacement.
Description
The utility model relates to a kind of appliance socket.
Growth in the living standard along with the people; household electrical appliances progressively enter each family, and when meeting thunderbolt or breaking down, high pressure or big electric current cause electrical equipment to damage; be equipped with protector electrical equipment is played a protective role, but high pressure or big electric current can cause the damage of protector equally.
The purpose of this utility model provides the protection socket that a kind of energy is anti-lightning strike, prevent high pressure and big electric current.
The purpose of this utility model realizes by following measure, socket can be common single function or multi-purpose type, connect power supply from the socket lead-in wire, article one, meet fuse RD between lead-in wire and the contact a, meet piezo-resistance R between contact a and the b, above-mentioned fuse RD and piezo-resistance R all are contained in the socket, form integrated.
Above-mentioned socket can be multipurpose socket.
The advantage of this socket is, when electrical network is struck by lightning or electrical network when breaking down, voltage or electric current have exceeded the calibration value of pressure sensitive voltage, moment the piezo-resistance two ends be short-circuited, fuse RD quick-break is protected electrical equipment.The cost of socket own is low, and it is convenient to change and repair.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is the circuit diagram of this socket.
With reference to Fig. 1 is an embodiment of the present utility model, and two lead-in wires of its socket 1 connect power supply, meets fuse RD between lead-in wire and the contact a, meets piezo-resistance R between contact a and the b, and this protective circuit is contained in the single-socket body.
This socket cost is low, and is better to electric prospection.
Claims (2)
1, the protection socket of a kind of anti-lightning strike, anti-high pressure, anti-big electric current; it is characterized in that socket 1 lead-in wire connects external voltage; article one, meet fuse RD between lead-in wire and the contact a, meet piezo-resistance R between contact a and the contact b, fuse RD and piezo-resistance R are contained in the socket 1.
2, protection socket according to claim 1 is characterized in that described socket 1 is multipurpose socket.
