Wherein, described performance element is electromagnetic relay or solid-state relay or thyristor.
The present invention has following beneficial effect:
Safety socket provided by the invention is by extension component, reset components and position detection unit, the inserting state of plug and socket can be judged, and determine the break-make of card and power supply according to this state, thus improve the fail safe of safety socket, and this safety socket structure is simple.
Accompanying drawing explanation
Fig. 1 is the outline drawing of embodiment of the present invention safety socket;
Fig. 2 is the housing interior structure schematic diagram of embodiment of the present invention safety socket;
Fig. 3 is the structural representation of card, extension component, reset components in the embodiment of the present invention.
Embodiment
For making those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, safety socket provided by the invention is described in detail.
As depicted in figs. 1 and 2, safety socket comprises housing 1 and the card 3 be located in housing 1.Be provided with jack 2 at the contact-making surface (face of fitting with plug) of housing 1, the inserted sheet 8 of plug is inserted in housing 1 by jack 2.
As shown in Figure 3, card 3 comprises the first card 31 and the second card 32, first card 31 and the second card 32 and is oppositely arranged, and connects as one in bottom, and namely card 3 is structure as a whole.Draw-in groove 7 is formed between the first card 31 and the second card 32.When plug and socket grafting, inserted sheet 8 is connected in draw-in groove 7, thus realizes plug and socket realization electrical connection.It should be noted that, card 3 also can adopt Split type structure, is namely connected with the second card 32 by the first card 31 with conductive component.
Composition graphs 2 and Fig. 3, safety socket also comprises extension component 4, reset components 5, position detection unit (not shown), processor 9 and performance element 10.Wherein, extension component 4 is located in the draw-in groove 7 of card 3, and moves in grafting direction.In the bottom of draw-in groove 7, namely the bottom of card 3 is provided with through hole 33, and extension component 4 is stretched in draw-in groove 7 from the bottom of card 3 by through hole 33.Extension component 4 comprises extension body 41 and is located at the protuberance 42 of extension body 41, and reset components 5 is located at the below of protuberance 42.When by plug insertion socket, inserted sheet 8 can promote extension component 4 and move down, and simultaneously reset components 5 is under pressure distortion.When being extracted from socket by plug, reset components 5 promotes extension component 4 and moves up and reset, and namely the active force of reset components 5 acts on protuberance 42.In the present embodiment, reset components 4 adopts the parts such as spring or shell fragment.Position detection unit is in order to detect the characteristic values such as extension component 4 such as distance, the elastic force relevant to position.When detecting elastic force, position detection unit adopts pressure sensor.When detecting distance, position detection unit adopts distance measuring sensor.Certainly, position detection unit also can adopt the transducer of other forms such as such as reflection sensor, voltage sensitive sensor, capacitance sensor, magneto-dependent sensor.
The detection signal of processor 9 receiving position detecting unit, and this detection signal is processed, then make the judgement be switched on or switched off, and this judgement is sent performance element 10.Performance element 10 is for performing the order of processor 9.When position detection unit detects that extension component 4 is moved down into default lowest order, position detection unit sends signal, and processor 9 sends according to the signal of position detection unit and connects order, and card 3 and power supply are connected by performance element 10.Performance element 10 can adopt electromagnetic relay or solid-state relay or thyristor etc. can realize the device of break-make.
Above embodiment is introduced for Three-hole socket.In fact, safety socket provided by the invention can also be used for two spring hole scokets.This safety socket both can be fixed in body of wall as fixed socket, also can be used for mobile socket, i.e. wiring board.
The safety socket that the present embodiment provides, by extension component, reset components and position detection unit, can judge the inserting state of plug and socket, and determines the break-make of card and power supply according to this state, thus improves the fail safe of safety socket.
Be understandable that, the illustrative embodiments that above execution mode is only used to principle of the present invention is described and adopts, but the present invention is not limited thereto.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement are also considered as protection scope of the present invention.
