Abstract

The six-prevention uncharged plug wire socket is an updated product which does not change the national standard requirement of the socket and the use habit of people for a hundred years. The power box is independently disconnected from the jack chamber and separately controlled, the plug wire seat is not electrified, the jacks are locked, and the plug assembly is switched on and off. When the plug is inserted into two side faces of the plug to push the wheel vehicle assembly and the limiting assembly to move along the through groove of the base in a direction, the plug is in contact with the power box in front to conduct an electric appliance, the rear communication indicator lamp is on, and otherwise, the lamp is off. Stable 'face-to-face' contact conduction is achieved. The area of the socket is far larger than the unstable conductive contact area of the traditional socket which clamps the plug sheet by the elasticity of the arc-shaped reed to form a line-to-plane structure, thereby eliminating the potential safety hazard caused by the contact deformation of the traditional socket reed and the self arc-shaped fatigue and easily deforming, and solving the three congenital structural morbid problems in the century history. The novel product has unique electric shock prevention, water prevention and fire prevention setting, double-switch interlocking multifunctional circuit application and a novel, green and environment-friendly appearance model.

Description

"six prevent" uncharged socket

Technical Field

The invention relates to the technical field of connectors for connecting electrical appliances with external power supplies. Solve traditional socket "line face to face" unstable conductive contact difficult problem for a century, the transformation realizes "face to face" stable conductive contact, possesses six kinds of safety power consumption safeguard function simultaneously: the novel generation product has the advantages of electric shock resistance, water resistance, electric leakage prevention, fire prevention, overload prevention and dust explosion prevention, and is green and environment-friendly in appearance.

Background

At present, the socket on the market is inconvenient for old, weak, sick and disabled to insert into the hole, and has a great potential safety hazard. The socket has the advantages that the traditional structure of various sockets is reserved for centuries, the spring plates bent into the arc shape generate opening and closing elasticity to clamp the plug plates to form 'line-to-surface' contact conduction, the contact surface is small in resistance, large in contact, unstable, easy to loosen and easy to shake, and the negative effect is that the surge multi-peak high-easy-flashing arc temperature rise caused by poor conduction is rapid in heating. In addition, the arc reed is often touched to deform due to plugging and unplugging actions or is easy to fatigue and deform due to self arc, so that a congenital structure is in a sick state, the situation that the electricity utilization is unsafe for users due to the fact that the jacks are electrified, fire accidents of various electrical appliances are often heard due to overheating or the explosion of the electrical appliances is caused due to poor conduction, and the situations that people are injured by electric shock and people are frightened by the fact that the plugs are inserted into the arc reed and flash fire are frequent. In recent years, although a plurality of new products are on the market, the congenital structure is not fundamentally cured, and unexpected 'aftersickness' occurs.

Disclosure of Invention

Aiming at the problems, the national standard requirement (the section of a common plug piece is 1.5x6.3mm) of the plug and the use habit of people for a century are not changed, an independent power box is arranged in the socket to be disconnected with a jack chamber for separate control, the plug is a master switch, and a plug-in and pull-out switch is inserted. The overall technical scheme takes the two-plug of fig. 15 as an example to show the structural principle and the plug-pull operation effect of the internal components: the plug is inserted, and its both sides face promotes wheel car subassembly 2a and spacing subassembly 2b of ship shape respectively and follows the displacement of base through groove branch, and preceding and power supply box contact switch on with electrical apparatus, and the pilot lamp on the spacing subassembly of back intercommunication is bright. The springs assembled at the front end and the rear end of each component generate positive elastic pressure on two side faces of the plug piece, and the gap is automatically adjusted to realize integral balance and stable face-to-face conductive contact, so that the problem that the traditional socket is unstable in line-to-face conductive due to the fact that the plug piece is clamped by the elastic force generated by bending the traditional socket into an arc reed is solved. And resetting indicator lamps of all the components of the unplugged plug are turned off. This kind of antischive dimension, with the width of plug piece side 1.5mm and contact reed length 8mm in the power supply box formation rectangle area of contact, it is equal to a straight thick copper wire conduction current volume of 2mm, far away from traditional socket lean on reed elasticity to press from both sides the line type area of contact that the positive 6.3mm of plug piece formed "line is opposite", its effect is that the big resistance of conductive contact surface eliminates surge peak current stability can be good not easily flashover and shake not become flexible temperature rise slow heating low, reinforcing power consumption sense of safety, can promote electric current and voltage application parameter. The bottom of the two sides of the wheel vehicle is locked by the spring steel balls and is directionally managed by the convex ribs, and a hole is not easy to pry or insert foreign matters when being played, so that people are not injured by electric shock. Thereby radically curing the major diseases of three congenital structural defects of the traditional socket.
