Abstract

The invention relates to a three-prevention safety socket which can prevent water, dropping off and electric shock and comprises a socket cover, a socket base, a linkage device, a plug pressing device and a switch and is characterized in that: the linkage device comprises linkage bars, a linkage bar shaft, sliding plates, the switch and a switch inserted bar; the plug pressing device comprises a safety baffle, a spring and a plug abutment plate; the linkage bar is arranged on the socket base through the shaft, and the sliding plate is arranged at the middle part of two linkage bars; the safety baffle is arranged at the other end of the linkage bar; a metal piece is arranged on the plug abutment plate; the spring is arranged at the side surface of the linkage bar; the switch is arranged on the socket cover; the switch inserted bar can be inserted in the diagonal plane between two sliding plates; reeds are arranged on the bottom part of the linkage bar and the socket base; under normal state the safety baffle can block jacks and prevent sprinkling water or rain from entering; only if the switch is pushed and the jacks are opened, the plug can be inserted into the jacks, the spring can tightly press the plug after the plug is inserted, thus not only greatly improving the security of the socket, but also overcoming the problems of easy loosening and poor contact of the plug in long term usage.

Description

A kind of water-proof anti-drop touch-proof safety socket

Technical field

The present invention relates to a kind of water-proof anti-drop touch-proof safety socket.

Background technology

Will relax in the long rear socket of time one that general socket is used, cause behind the plug socket is not that contact is bad, be exactly not contact, the plug that also makes easily that has falls down, all lie in when especially some removable porous sockets generally use in desktop or ground, people's teacup bumps because of carelessness and spills or drink water and all can have water to leak into when rainy and cause short circuit, general in addition socket also has a maximum shortcoming, be exactly dangerous, metal insert in the jack exposes, and the metallic particles that puts in hand or fall into conduction as child is very easy to short circuit or hurts sb.'s feelings.In such cases, general people have to change socket.

Summary of the invention

The invention provides a kind of water-proof anti-drop touch-proof safety socket, this socket can not only compress the plug metal film that inserts in the jack, and can also live jack by automatic catch, open again when inserting plug,, and have water-proof function concurrently at ordinary times so that when not inserting plug, more can increase the fail safe of socket, generally speaking, watering or rain in the socket can not only overcome the shortcoming of above-mentioned common socket like this, but also has added a more convenient safe switch for socket.

The technical solution adopted for the present invention to solve the technical problems; With safety screen jack is blocked automatically, when the need plug inserts, by the switch that adds in addition on the socket, switch exposes jack after strutting safety screen, and plug could insert, after plug inserts, safety screen in the socket on the sheet metal on the plug, makes power connection by spring compression simultaneously.

The invention has the beneficial effects as follows; After adopting said structure, the security performance of socket improves greatly, has also avoided socket with jack is lax long afterwards simultaneously, and with the plug loose contact, and water inlet and jack expose the generation of phenomenon easily.

The present invention includes; Socket cover, socket base, linkage, the plug hold down gag, is characterized in that switch; Said linkage comprises; Trace, trace axle, slide plate, switch, switch inserted link are formed, and the plug hold down gag is made up of safety screen, spring, plug backup plate; One end of trace is installed the trace axle, the trace axle is connected with socket base, the trace axle is installed on the base of socket, slide plate is installed in the middle part of two traces, a slide plate side inwards is the inclined-plane, safety screen is installed in the other end of trace, the plug backup plate is installed between two safety screens, the plug backup plate directly is connected with socket base, on the plug backup plate sheet metal is installed, sheet metal is connected with binding post, in the side of trace, position near safety screen is provided with the spring erection column, one end of spring inserts in the spring erection column, and the other end of spring is placed in the spring base on the sidewall of socket base, and switch is installed in the position of just going up in the middle of two slide plates, make people after pressing switch, the switch inserted link can just in time insert the scarf between two slide plates, and makes it strut two traces, and the distance that its trace slides is advisable with the distance that just in time makes safety screen can open the jack of socket, the switch installing rack is installed on the socket cover, and switch is installed on the switch installing rack.

The function of waterproof is finished by the reed and the safety screen that are installed in trace bottom, it is characterized in that, and the bottom in the position of close the safety screen of trace, the installation reed, reed is fixed by the reed screw, and the reed screw is installed on the socket base.

Conductive metal sheet of the present invention, except that above-mentioned be installed on the plug backup plate, also can be installed on the safety screen, sheet metal is made L shaped, and be wrapped in the side and the bottom of safety screen, make the reed of sheet metal and bottom can keep sliding contact forever, the sheet metal of safety screen bottom directly is pressed on the reed under the safety screen, and can be free to slide on reed, reed is connected with binding post, in material object, wiring hole directly is installed on the safety screen, sheet metal directly is connected with wiring hole.

In actual production, jack of the present invention and button distance too closely cause the bad installation of Three-hole socket, for this reason, the present invention adopts another kind of method, promptly the button inserted link is made L shapedly, the button inserted link is extended by vertically changing into to horizontal direction, strut slide plate by the extension rod that extends out.

Water-proof function of the present invention also can adopt another kind of method, promptly raise safety screen without metal spring leaf, and directly under trace, the place of close safety screen is provided with one and raises the slope, make two traces when closing up, under the effect on slope, directly raise, and be pressed on the jack automatically by elastomeric material.

Safety screen has two kinds of methods to make, and is a kind of for to be made by a kind of insulating material, when safety screen blocks jack, and all slits on the airtight jack of energy, another kind is that two kinds of insulating material are made, and beneath is rigid plastics, and top is elastomeric material.

After the present invention adopts said method, the security performance of socket significantly improves, not only socket can not relax after injecting plug, cause loose contact, and general child can stretch hand yet and contacts power supply, some foreign material can fall yet, general rain or accidentally drop also can not leak in the socket phenomenon that can cause short circuit phenomenon or hurt sb.'s feelings not after having spilt water.
