Abstract

The utility model discloses an anti-fire automatic power off socket, which comprises an insulating shell, a button switch on the insulating shell, a metal film threading in the cavity of the insulating shell, and a ground wire film threading; at least two light springs are respectively and symmetrically arranged between the wall of the cavity of the insulating shell and an exterior side of an exterior film threading of two rows of metal film threading in the cavity of the insulating shell; a contact terminal is arranged at an end part of the exterior side of the exterior film threading; metal contact sheets are arranged at corresponding positions to the exterior side of the contact terminal for respectively connecting a live wire or a zero line. When the socket is used, only a master switch is needed to be turned on and a plug is needed to be inserted; owing to the spring action in the cavity of the insulating shell, the contact terminal at the end part of the metal film threading can be automatically connected with the metal contact terminal on a fusible link protecting device to lead a indicator light of the socket with electricity to be light; when power consumption of the socket is over big, and the electric power is overloaded, the fusion link can be blown out, and the socket is power off, thus avoiding the occurrence of a fire and ensuring the safety of the power utilization.

Description

The anti-fire socket that cuts off the power supply automatically

Technical field

The utility model relates to a kind of electrical equipment and patches device, particularly relates to a kind of anti-fire socket that cuts off the power supply automatically.

Background technology

Supply socket is a kind of widely used circuit connection device; the supply socket of present domestic use does not have overload protection function mostly; just rely on the anti-flammability of supply socket to shield; when power during greater than the socket bearing capacity; socket can burn out; cause fire because of short circuit easily; have only push-button switch to control the charged work of whole socket in addition on the socket, if when electrical work, socket is out of order; fire has taken place; owing to can not in time cut off the power supply, just may make fire that the possibility that enlarges and spread is arranged, when the socket outage is arranged again; socket is still charged, once water inlet also electric shock accidents can take place.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of power on/off freely, can prevent fire, and is easy to use, and cost is low, applied widely, for ease of maintenaince with the effective anti-fire socket that cuts off the power supply automatically.

The technical solution of the utility model is achieved in that a kind of anti-fire socket that cuts off the power supply automatically, comprise metal insert and ground wire inserted sheet in insulation crust, the push-button switch above the insulation crust and the insulation crust chamber, respectively be provided with at least two light springs symmetrically between the outer inserted sheet outside of two row's metal inserts in the insulation crust chamber and the insulation crust chamber wall, the inserted sheet outboard end is provided with contact outside, be equipped with the metal contact at corresponding position, the contact outside, be respectively applied for connection live wire or zero line.

Be equipped with the metal contact at corresponding position, the contact outside, be respectively applied for connection live wire and zero line.

The front end of described metal contact is provided with fusible link.

The inboard of described metal insert is provided with interior inserted sheet, is in series with resistance and indicator light between two interior inserted sheet.

The utility model compared with prior art and has following advantage:

One, the anti-fire of the present utility model socket that cuts off the power supply automatically, in the insulation crust chamber, be provided with two row's metal inserts, the outer inserted sheet outside at metal insert is provided with light spring, be provided with contact in the outer inserted sheet outboard end of metal insert, and contact is corresponding with the metal contact that is fixed on the fusible link both sides, during use, as long as open master switch, insert plug, because the elastic force effect of spring, contact and metal contact are connected, and socket will automatic charged work.

Two, the anti-fire of the present utility model socket that cuts off the power supply automatically is provided with fusible link in the insulation crust chamber, and excessive when socket power consumption, during the too high overload of electrical power, fusible link will fuse, thereby makes the socket outage, avoid fire generation, guarantee the safety of electricity consumption.

Three, the anti-fire of the present utility model socket that cuts off the power supply automatically, push-button switch also is housed on socket, control whole socket charged state, because this socket is elastic force effect control circuit open close of utilizing spring, therefore when not electricity consumption, even without turning off push-button switch, socket can be not charged yet, so socket just electric shock accidents can not take place.

Four, the anti-fire of the present utility model socket that cuts off the power supply automatically, as long as pull out plug, the spring in the insulation crust chamber extends naturally, contact on the metal insert and the metal contact on the fusible link disconnect naturally, socket cuts off the power supply immediately, does not need to go to turn off push-button switch again, and is therefore simple to operate, convenient.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing

As shown in drawings, a kind of anti-fire of the present utility model socket that cuts off the power supply automatically, comprise insulation crust 1, the push-button switch 2 above the insulation crust 1 and metal insert 3 and the ground wire inserted sheet 4 in insulation crust 1 chamber, respectively be provided with at least two light springs 7 symmetrically between outer inserted sheet 31 outsides of two row's metal inserts 3 in insulation crust 1 chamber and the insulation crust 1 chamber wall, inserted sheet 31 outboard end are provided with contact 8 outside, be equipped with metal contact 10 at corresponding position, contact 8 outsides, be respectively applied for connection live wire or zero line.

Be equipped with metal contact 10 at corresponding position, contact 8 outsides, be respectively applied for connection live wire and zero line.

The front end of described metal contact 10 is provided with fusible link 9.

The inboard of described metal insert 3 is provided with interior inserted sheet 32, is in series with resistance 5 and indicator light 6 between two interior inserted sheet 32.

Operation principle

The anti-fire of the present utility model socket that cuts off the power supply automatically, be respectively to be provided with two light springs symmetrically between the two row metal inserts outsides in the insulation crust chamber and the insulation crust chamber wall, outer inserted sheet outboard end at two row's metal inserts respectively is provided with contact respectively, also respectively be provided with the fusible link safeties that two ends are fixedly connected with the metal contact respectively in the contact both sides, the metal contact is corresponding with contact; One shift knob is housed on insulation crust controls whole socket charged state; Be provided with interior inserted sheet in the inboard of metal insert, be in series with resistance and indicator light between two interior inserted sheets, resistance can prevent that indicator light from burning out, and indicator light is used to show the charged or off-position of socket; Be provided with ground wire jack at the insulation crust two ends, to guarantee the fail safe of socket electricity consumption.

When using this socket, only need open master switch, insert plug, because the spring action in the insulation crust chamber, the metal contact on the contact of metal insert end and the fusible link safeties can be connected automatically, makes the charged indicator light of socket bright; Excessive when socket power consumption, during the too high overload of electrical power, fusible link will fuse, the socket outage, thus can avoid the generation of fire, guarantee the safety of electricity consumption.
