Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this has the socket of automatic power power down function, and it comprises:
One jack body 10; This jack body 10 has two holes at least; This two hole is respectively first hole 11 and second hole 12, and first latch 300 of plug and second latch 400 are inserted to be used for energising, in this first hole 11 and second hole 12 conducting strip is arranged respectively; Be first conducting strip 13 and second conducting strip 14; Be connected to first conductor wire 15 and second conductor wire 16 after this conducting strip respectively, be used for being connected, wherein in this first conductor wire 15 and 16 parallel connections of second conductor wire, one switching circuit unit 200 with external current source 100.Wherein this external power source 100 is in the outside of this jack body 10, and this external power source 100 is used to the electric power that provides required, is generally alternating current.Switching circuit unit 200 is provided with a make and break contact, pounds and 30 be connected in make and break contact and a center, and a pound distal process of 30 of center goes out on the surface between jack body first hole 11, second hole 12.Pound and 30 have auto-reset function in the center; When the center pounds 30 when being depressed; This make and break contact conducting, switching circuit unit can make first conductor wire 15, second conductor wire 16 and external power source conducting, when the center pounds 30 when being upspring; Make and break contact breaks off, and switching circuit unit 200 can make first conductor wire 15, second conductor wire 16 break off with external power source.
As shown in Figure 2, be a kind of structural representation of switching circuit of the present invention unit 200, it comprises:
One transformer 20; This transformers connected in parallel is in this external current source, this transformer 20 respectively once side 21 and secondary side 22 be parallel between first conductor wire 15 and second conductor wire 16, will exchange the circuit that (AC) high tension voltage is done a step-down rectifier voltage stabilizing; Make the high voltage step-down of this primary side 21; The voltage of this secondary side 22 is reduced to general low-voltage (direct voltage) commonly used, like 5V or 4.7V, a low power power supply of dc low-voltage is provided.
The secondary side 22 of transformer 20 is connected with make and break contact, and an end of pounding in the center is connected with make and break contact, and the other end is inserted following time when socket like this and just can be pounded 30 in the center of pressing down for protruding on 12 of this jack body 10 first holes 11, second hole.Make and break contact and a signal controller 40 also, this signal controller 40 is positioned on the circuit board of this switching circuit unit 200, and after the make and break contact conducting, the secondary side 22 of transformer 20 gives the signal controller 40 power supplies, and signal controller 40 just can send signal.
One relay 50, this relay 50 is series at this first conductor wire 13, and can the circuit that be used for controlling this external current source 100 conducting.Relay 50 can be mechanical relay or the brilliant lock body of electronic type two-way admittance TRIAC.The control line of relay 50 is connected with signal controller 40; When this center pounds 30 when being pressed down fully, signal is sent in make and break contact conducting, 40 effects of signal controller connects this relay 50; The circuit turn-on that whole this external current source 100 is connected; Produce electric current, the load energising that plug is connect produces action.
When first latch and second latch of plug touches first conducting strip 13 and second conducting strip 14 to this jack body 10; 30 do not depress fully if having this center pounded; Just can conducting; Can be used for inspecting socket and whether be used, and first conducting strip 13 of first latch 300 and second latch 400 of avoiding plug and this jack body 10 and second conducting strip 14 be because of immediate current produces spark, the danger that sets off an explosion.
Like Fig. 3, shown in 4, wherein this switching circuit unit 200 also comprises:
One delay circuit 60, this delay circuit are series at this relay 50, be used to make circuit to form path after, have one second time of delay, just can switch on through circuit after a second, strengthen the fail safe of socket.
As shown in Figure 5, this jack body also comprises:
One ground connection hole 70, this ground connection hole 70 are positioned on the face at this first hole 11 and second hole, 12 places, are used to connect lead wire and earth wire, as the function of ground connection.
When first latch 300 of socket contacts respectively to first conducting strip 13 and second conducting strip 14 of this jack body 10 with second latch 400; Depressing this protrudes in socket and has the center of hole face to pound 30; Make this inner signal controller 40 of socket act on; Send the circuit that signal makes whole this external current source 100 of these relay 50 conductings, and then generation electric power moves the load of plug.In the present technique scheme; If first latch 300 of socket and first conducting strip 13 and second conducting strip 14 that second latch 400 does not touch this jack body 10 fully; And not depressing this fully protrudes in socket and has the center of hole face to pound 30; Or plug pulled up, this jack body 10 can not be switched on and can not reduced the danger of blast because of immediate current does not produce spark this moment.And in this programme, increase the device of a delay circuit 60, can make circuit after forming path, have a bit of time of delay, spent time of delay, just can switch on, increase its fail safe.
Advantage of the present invention is when socket does not use, and can stop power supply fully, unlike traditional socket, when not using, still is in the state of energising always, is prone to cause the accident of electrification, electric leakage.And in this programme, socket can not cause the accident of electric leakage or electrification when jack is exposed, can avoid when plug does not contact with socket as yet fully; Just because of immediate current produces spark, the danger that sets off an explosion must be after plug inserts socket fully; And pound and just can switch in the center of depressing; And do of short duration power supply delay function, can be used in factory and pit etc., to improve the security reliability of electricity consumption.
And this jack first guide card and second guide card respectively are an exposed space, with the insertion of convenient plug electric power are provided; The pound institute's switch driven contact and first guide card and second guide card of center is two spaces that isolate fully, that is to say that make and break contact has electricity, but he isolates with the external world, therefore can accomplish waterproof and prevent the function of electrification.
More than a kind of socket that advances to have the automatic power power down function that the embodiment of the invention provided has been carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
