Abstract
The automatic switch plug consists of casing, underplate, button-operated reset mechanism, mutual inductor, electromagnetic iron, electronic control circuit and load jack. After the load is off, it will cut off the power supply to load and this ensures the safety and power saving.
Description
A kind of electronically controlled automatic switch plug for AC supply that has scheduled delay to disconnect.
At present there is following defective in 22 volts of ac power plugs that use: 1, out of service when load, when plug not being pulled up again, plug and line part all are in the lead current flow condition, this comprises partial circuit, the element of load, also comprise not charged source switch or only with load of A-wire mains switch etc., must produce the extra power consumption of load, and quicken the aging of electric component, be prone to electric leakage and load circuit and be in accidents such as the easy electric shock of high-voltage state.2, because load and plug have long line, insulating protective layer cracky, the grinding cracks of (non-loaded) line during frequent charged dragging very easily cause electrical short-circuit, ground connection, catch fire, accident such as electric shock.Existing in a word dangerous, uneconomical, the not electrical energy saving of plug.
The object of the present invention is to provide a kind of need not pulling up and the plug of energy safety utilization of electric power, electrical energy saving, planned power consumption from supply socket.
Structure of the present invention and operation principle are as follows: shown in accompanying drawing 4 and 1, plug blades 1 is moulded casting on shell 11, front end outside, play the effect of socket power jack, twice vertical bending of chine pressed in rear end in shell 11, fix a silver contact on the afterbody and make fixed contact usefulness, when button 3 is pressed and moving contact 2 crimping.Fixed contact 8 in the accompanying drawing 1 is fixed in the shell 11, and a silver contact is arranged on it, and the lead-in wire 15 of instrument transformer 10, electromagnet coil 17, electronic control circuit 12 also are connected with fixed contact 8 respectively.Shell 11 upper left corner parts are to use transparent material in the accompanying drawing 1, and other parts are opaque materials.Plug blades 1 is inserted 220 volts of AC Power supply socket, press the button 3, its top power supply indicator is bright, and the hook inclined-plane of its underpart Removable hook and locating button 6 fastens mutually, but owing to the effect of spring 4 and 5 also can be broken off relations voluntarily button 3 is upwards resetted.At this moment, the opening groove up at the moving weighing apparatus of electromagnetism iron 7 tops just in time coincide with the hook place voluntarily under the upwards thrust of spring 9 two hooks is pinned.After pressing the button 3, spring 5 forms electric contact with silver contact on the moving contact 2 crimping plug blades reliably 1 and the contact on the fixed contact 8, and spring 4 is that button 3 is resetted.Shown in accompanying drawing 1,2, two thin steel column A are solid on locating button 6, and moving contact 2 and spring 4,5 equal kinks are on thin steel column A, but knee-action only forms the break-make bridge of power supply, and electric loop is at this moment:
When no running load, the elementary no-load current of current transformer 10 flows through, then secondary influence electricity signal output, but electronic control circuit 12 energising work.In the accompanying drawing 3: the base stage of transistor T connects the secondary voltage signal end of current transformer 10, because of no signal of telecommunication output, makes T be in cut-off state, delay capacitor C
1Begin charging, the 3rd pin output negative voltage signal of integrated circuit (IC), the trigger electrode of bidirectional triode thyristor K ends because of no positive voltage signal triggers, and electromagnet coil 17 non-transformer paths are not worked.As delay capacitor C
1When being charged to certain circuit work power voltage, IC the 3rd pin output positive voltage signal, K promptly triggers and conducting, and electromagnet coil 17 energisings produce electromagnetic force, with the 7 downward adhesives of the moving weighing apparatus of electromagnetism iron.This is the time-delay disconnection process of control circuit of the present invention, electromagnetism moving weighing apparatus iron 7 open tops groove up breaks away from the hook place of button 3 and locating button 6 immediately, under spring 4,5 effects, button 3 rebounds reset, deenergization, button 3 top power supply indicators extinguish, and the moving weighing apparatus of electromagnetism iron 7 upwards rebounds because of the effect of spring 9, treat to pin next time hook; When running load inserted, instrument transformer 10 secondary then exported an ac voltage signal with elementary same frequency, through diode D
3Be added to the base stage of transistor T after the rectification, T immediately saturation conduction, with delay capacitor C
1Short circuit, integrated circuit (IC) will be exported a negative voltage signal forever up to load termination operation this moment.Bidirectional triode thyristor K ends because of negative voltage signal control, and the moving weighing apparatus of electromagnet coil 17 and electromagnetism iron 7 is not worked.If running load stops, circuit will repeat above-mentioned time-delay reset process, deenergization.
As shown in Figure 1, there is the inclined-plane that coincide with electromagnetism moving weighing apparatus iron 7 open tops groove face up in the outside, Removable hook lower end of button 3 bottoms, there is inclined-plane to left down the inboard, it on this inclined-plane a notch, notch constitutes by a horizontal plane with towards upper right oblique plane, can embed the inner tank mouths of locating button 6 lower ends, there is the inclined-plane that coincide with electromagnetism moving weighing apparatus iron 7 open tops groove face up in the outside of locating button 6 lower ends, there is a notch inboard, notch by one left declivity the plane and constitute towards upper left oblique plane.
Shown in accompanying drawing 1,2, button is for 3 times spring 5 successively, moving contact 2, spring 4, after press the button 3, bottom Removable hook and locating button 6 were pinned by the moving weighing apparatus of electromagnetism iron 7 open tops groove up, spring 5 can be crimped on moving contact 2 on plug blades 1 and the fixed contact 8 reliably.
As shown in Figure 1, opening groove is up arranged at the moving weighing apparatus of electromagnetism iron 7 tops, when button 3 is pressed, with the Removable hook and locating button 6 pinnings of its underpart.Protrusion garden, the middle part plate edge that moves weighing apparatus iron 7 at electromagnetism has a groove, and up and down being stuck in freely on the guide plate 18 avoided occurring 7 rotations of the moving weighing apparatus of electromagnetism iron and caused the Removable hook of button 3 bottoms and the phenomenon that locating button 6 can not enter open top groove up.
The present invention has compared following advantage with existing plug: 1, when no running load or running load termination, automatic time delay cuts off and is loaded to the power supply of supply socket, and is even do not extract the present invention, safe and reliable equally, and can see intuitively and cutting off the electricity supply from upper left corner transparent window.2, easy to use, saving electric energy.
