Description
Technical field
The utility model relates to a kind of socket more particularly to a kind of false-touch prevention sockets with overcurrent protection function.
Background technique
The safety accident of power grid happens occasionally, wherein route overcurrent fire, aging circuit fire, electricity consumption maloperation electric shock etc.
Safety accident caused by situation happens occasionally, and largely will cause weight huge economic loss and human safety issues.Current inserts
Seat insert row, largely has a single function that safety is inadequate, has the safety socket of overcurrent protection also expendable, repairs after protection is primary
Multiple trouble has the socket structure of the protection of protection against electric shock complicated, expensive.A kind of socket insert row is needed to solve the above problems.
Chinese patent (notification number: 203434386 U of CN) discloses a kind of safety socket with overcurrent protection comprising
Jack body, the inlet wire of jack body have zero line side, zero line and ground terminal, it is characterized in that: be equipped with can for the zero line
Line disconnection and the automatic recovery of power supply after all loads all remove in the electric current overrate that high power load generates
Overcurrent protector, overcurrent protector includes protector outer casing, the bimetal release being encapsulated in protector outer casing and fever
Resistance, thrermostatic bimetal-plate switch are connected in parallel in zero line with heating resistor.The safety socket is equipped with overcurrent protector, once circuit
It is middle using high-power electric appliance or load short circuits when, can automatically cut off the power, until whole loads on socket remove or short circuit
It can automatically reset after Resolving probiems, socket restores to work normally, the patent double heat gold in the case where short circuit occurs in load
Belong to piece switch to disconnect because high current is generated heat, electric current is by heating resistor, since heating resistor resistance value is very big, keeps main circuit electric
Stream reduces, and realizes overcurrent protection, and the design is sufficiently complex, and the thrermostatic bimetal-plate construction of switch is complicated, at high cost, is not suitable for work
