Abstract
The utility model relates to self locking safety plug and socket. A safe lock is composed of safety plug and socket for the power supply, an insulating lock type twisting core and a lock wall positioning post on an insulating base. Electrode sheets are respectively installed on the bottom and base of the lock type twisting core, and the plug is the key shape, When the socket is not inserted with a special plug, the lock type twisting core can not be rotated, the conductive sheet on the lock type twisting core and the conductive sheet on the base are disconnected, so, when no power is arranged in the socket and the special plug is inserted, the lock type twisting core can be rotated, when the lock type twisting core is rotated by 90 DEG, the two conductive sheets are contacted, and the power supply is switched on. At this point, the plug is fixed on the socket and is unable to be pulled out, and only when the plug is rotated to the original position, the plug can be pulled out.
Description
The utility model is a kind of safety powr supply plug socket.
At present, known supply socket has electricity all the time on the electrode in the jack, and child's nature are active and curious, just will cause electric shock accidents if they touch electrode with finger or conductor, and its consequence is hardly imaginable.Also have a kind of socket that electrical shock protection is arranged now, its design principle is just to implement protection after electric shock, rather than is just taken precautions against before electric shock, and price is very high.
The purpose of this utility model provides a kind of safety plug socket of taking precautions against just implemented before electric shock, promptly plug insertion socket before and overall process enforcement safeguard protection from start to finish later on.
The purpose of this utility model is achieved in that in the loam cake of insulation, the locking-type of insulation is changeed lock wall reference column on core and the insulator foot and has been formed a lock that general is not got down from horse, locking-type is changeed the jack that plug is arranged on the core, on the bottom of locking-type commentaries on classics core and the base electrode slice is housed respectively, locking-type is changeed core and with locking in the wall reference column two groups of spring holders is housed, plug is a key shape, is the key on the socket, is again attaching plug simultaneously.When not inserting special-purpose key shaped plug, conducting strip and the conducting strip on the base that locking-type is changeed on the core are discontiguous, so do not have in the jack of the present utility model, locking-type is changeed core and is fixed by spring holder, can not rotate, at this moment, with also not getting an electric shock in the conductor insertion jack.When using private key cochlear plug of the present utility model to insert in the jack, locking-type commentaries on classics core can rotate, when rotating 90 °, and the contact of two conducting strips, power connection.When plug began to rotate, plug was fixed on the socket (general of lock do not get down from horse principle) automatically, can not extract, and only rotates back into original position, and plug just can be extracted.
Because employing such scheme, the utility model are at any time, the people does not reach electrified body, thus be very safe, and also structure is also very simple.
Below in conjunction with drawings and Examples the utility model is further specified.

When socket of the present utility model is not plugged plug special, conducting strip (4) on the locking-type commentaries on classics core disconnects with the conducting strip (7) on the base, do not have in the jack, and the two pairs of alignment pins in centre (3) that locking-type commentaries on classics core (2) is locked in the wall reference column (6) are fixing, can not rotate, the insertion anything else also can not rotated.When inserting the key shaped plug, the two pairs of alignment pins in the centre in the alignment pin (3) are risen mutually neat with locking-type commentaries on classics outer core by the plug tooth top, change core (2) and can rotate, and when turning to 90 °, change core conducting strip (4) and contact power connection with base conducting strip (7).At this moment, the top a pair of alignment pin (3) that plug (1) is changeed in the core (2) by locking-type is fixing, can not extract, simultaneously, locking-type commentaries on classics core (2) outer wall is withstood by following two pairs of spring holders (3), shaking phenomenon should not occur, thereby guaranteed the energising quality, plug goes back to the original place, plug could be extracted, and has not had electricity in the jack this moment.
Claims (5)
1, a kind of self-locking safety power supply plugs and sockets, by plug, the insulation loam cake, insulator foot, the base conducting strip, the loam cake hold-down screw is formed, it is characterized in that in the loam cake (13) of insulation, the locking-type of insulation is changeed lock wall reference column (6) on core (2) and the insulator foot (5) and has been formed a lock that general is not got down from horse, locking-type is changeed the jack that plug (1) is arranged on the core, on the bottom of locking-type commentaries on classics core and the base electrode slice is housed respectively, locking-type is changeed core and with locking in the wall reference column two groups of spring holders (3) is housed, plug is a key shape, it is the key on the socket, be again attaching plug simultaneously, when not inserting special-purpose key shaped plug, conducting strip (4) on the locking-type commentaries on classics core is discontiguous with the conducting strip (7) on the base, so do not have in the jack of the present utility model, locking-type is changeed core and is fixed by spring holder, can not rotate, at this moment, with also not getting an electric shock in the conductor insertion jack, when using key shaped plug of the present utility model to insert in the jack, locking-type is changeed core and can be rotated, when rotating 90 °, the contact of two conducting strips, power connection, when plug began to rotate, plug was fixed on the socket (general of lock do not get down from horse principle) automatically, can not extract, only rotate back into original position, plug just can be extracted.
