Description

A kind of socket that has current protection

Technical field

The utility model relates to a kind of socket that has current protection, belongs to the jack technology field.

Background technology

Present socket only has overload protection function, and the plug of electrical appliance is plugged after the socket, and the just direct momentary connection power supply of electrical appliance reaches rated power; When the plug of electrical appliance also instant cut-off immediately after socket pulls out, so not only influential to the useful life of electrical equipment, cause easily that also spark causes fire and so on; At present, also do not have a kind of protection electrical equipment that can play to play cushioning effect and prevent common wiring board with electrification, moreover conducting strip also is that spring or spring-piece type are fixed mostly, doing like this to increase the manufacturing production cost.

Summary of the invention

In order to overcome above-mentioned deficiency; The purpose of the utility model is to provide a kind of socket that has current protection; It can make electric current reach specified user mode gradually from zero when using, thereby has the outage of process to play protective effect and some unexpected preventions to electrical equipment after the outage.

The utility model comprises upper shell and lower house; Upper shell is fixedly connected with lower house, and is porose on the upper shell, and the hole is provided with a capping; Upper shell is fixedly connected with lower house; There are housing clamping plate one at the middle part of the inside of lower house, housing clamping plate two, housing clamping plate three, housing clamping plate four; Housing clamping plate one, housing clamping plate two, housing clamping plate three, housing clamping plate four are into a single integrated structure with lower house; Be installed with magnetic stripe between housing clamping plate one and the housing clamping plate two; Be installed with magnetic stripe between housing clamping plate three and the housing clamping plate four; Conducting strip one is by iron plate one, iron plate two, and iron plate three, iron plate four, housing clamping plate two, housing clamping plate four are fixedly mounted in the lower house; One side of conducting strip has iron plate one, iron plate two, iron plate three and iron plate four; The opposite side of conducting strip has housing clamping plate two and housing clamping plate four; Conducting strip two is by housing clamping plate one, housing clamping plate three, and iron plate five, iron plate six, iron plate seven, iron plate eight is fixedly mounted in the lower house; One side of conducting strip two is housing clamping plate one and housing clamping plate three; The opposite side of conducting strip two is iron plates five, iron plate six, iron plate seven, iron plate eight; One end of conducting strip two connects an end of inductance; The other end of inductance is an inductance leads, and inductance leads flexibly connects an end of fuse, and the other end of fuse flexibly connects an end of conducting strip three; Introduced circumscripted power line in the lower house; Being fixedly mounted in the lower house of circumscripted power line near the end, the live wire of circumscripted power line connects conducting strip three, and zero line connects conducting strip one end.

The utility model operation principle: after inserting plug, because inductance is a kind of energy-storage travelling wave tube, when just plugging in; Inductance begins charging, and it is zero that branch goes most of electric current, the electric current that and then takies to reduce until at last gradually; After the utmost point is accomplished charging in the short time fast, become and make the lead function, and electrical appliance part is just opposite like this; Flow through electric current and increase gradually, use power to increase rated value gradually; When pulling the plug out of the socket, inductance sparks, and electric current fades away to reach protection electrical appliance and other unexpected purpose of prevention in the protection electrical equipment.In addition, above-mentioned said fuse is meant the general insurance silk, can protect different electrical appliances with different specifications; Also can require to change suitable fuse according to actual electrical appliance power demand and individual.
