Description
Technical field
The present invention relates to the plug device field for electrical outlets, especially a kind of power plug extracts system。
Background technology
The latch of plug is when contacting with socket aperture, and in order to ensure good electrical contact and have firm retentivity, the joint of described latch and contact is generally of very strong engaging force or frictional force。This generally requires bigger withdrawal force from socket when being extracted by plug；Therefore, this gives manually to pull the plug out of the socket and brings difficulty。
And, when manually extracting, due to unstability firmly, it is easy to make the process that latch unplugs produces spark phenomenon with electrical contact, jeopardize equipment and personal safety。
Summary of the invention
It is an object of the invention to provide a kind of power plug and extract system, it can overcome defect of the prior art。
A kind of power plug according to the present invention extracts system, including dsp controller, motor-drive circuit and plug device, support body that described plug device includes being fixedly installed external shell and fix two latches being connected and being symmetrical set with described support body, said two latch in order to be inserted in the hole of socket with respectively with contact electrical contact, described support body also slidably engages two be symmetrical set and backs down column piece, said two back down column piece structure specular and each described in back down column piece be included in lower end in order to back down suspension column with described socket engages, the wedge-shaped impression on the side faced out of column piece is backed down described in being positioned at, back down described in being positioned at column piece towards side at upper stress flange with at lower stress flange, and the spacing end in order to engage with described external shell at upper end, described spacing end engages it is thus possible to bias against described external shell by the described described spacing end backing down column piece with top compression elasticity part, described support body is correspondingly provided with backing down described in can horizontally slipping and being pressed to by elastic top pressing spring top pressure the wedge pin of column piece with wedge-shaped impression, the exposed end of described wedge pin is provided with and the wedge-shaped head of described wedge-shaped impression form fit；The middle part of described support body is provided with drive motor, the screw flight driven by described drive motor is combined with and is led and be fixed with in periphery the symmetrical female thread drive block stirring protuberance by guide rod, described dsp controller is electrically connected with described drive motor by motor-drive circuit, thus controlling the rotation of described drive motor, described drive motor rotates and drives female thread drive block described in described screw drive to move, described each stirring in protuberance symmetrical stretches into be backed down described in column piece at upper stress flange with between lower stress flange corresponding, described support body is also equipped with the accumulator cell assembly of symmetrical distribution, in order to provide electrical power to described drive motor；Thus, when in end spacing described in original state by described top compression elasticity part bias during against described external shell, said two latch allow to be inserted in the hole of described socket with respectively with contact electrical contact；When said two latch is disengaged by needs from described contact, controlled the triggering of described drive motor by dsp controller by motor-drive circuit and run, at lower stress flange the engaging and make of column piece described in back down column piece move downward thus described female thread drive block moves downward so that stirring protuberance described in each with corresponding backing down, described in back down suspension column with described socket effect so that said two latch starts to extract from described socket；When described back down column piece continue to move downward and make described wedge-shaped impression to start to engage with described wedge-shaped head time, the elastic reaction of described elastic top pressing spring makes described wedge pin accelerate to move downward the described column piece that backs down so that said two latch quickly disengages with described contact。
Valuably, wherein, after described plug device is removed from socket, controlled to stir protuberance described in the driving of described drive motor antiport by dsp controller by motor-drive circuit to engage at upper stress flange with described, and back down column piece described in making and move upward so that described wedge-shaped impression departs from and the joint of described wedge-shaped head, described in back down column piece and under the effect of described top compression elasticity part, return described original state so that next time inserts socket。
In the present invention, due to be provided with can with socket interact and back down back down column piece, therefore, it is possible to power ground latch is separated with socket。And backing down two the stress protuberances arranged on column piece one on the other, hold the driving protuberance driving threaded block therebetween, so that described in back down column piece can drive described in back down the up and down motion of column piece, back down column piece described in allowing again, with described screw drive block, there is a degree of asynchronism；So, owing to being provided with the wedge pin by elastic top pressing spring top pressure to avoid striking sparks by the two quickly being separated time completely disengaged at latch and contact, this allowed asynchronism can allow for described in back down the unexpected accelerated motion of column piece。Arranging storage assembly can utilize electrical contact to charge in plug insertion process。Whole device can effectively solve the problem that the problem that electrical contact plug not easily pulls away, and safe and reliable to operation, easy to use。
