Abstract
The utility model discloses a power-supply bayonet whose plug can automatically eject from the socket, aiming to provide a new type power-supply bayonet which does not need to directly pull-off the plug in live line work by hand. The technical proposal is that the plug is provided with a permanent magnet; the plug socket is provided with an electromagnet. The permanent magnet and the electromagnet have mutually exclusive function. The current supply and the control circuit of the electromagnet is provided with a switch controlled by a heat release infrared sensor. The utility model is applicable to the working occasions requiring constantly plugging and pulling the plug of the electrical appliance.
Description
A kind of low voltage power transmission device of technical field, more particularly, it relates to the latch in a kind of low voltage power transmission device.
Technical background is in daily electrical equipment, and most of electrical equipment are connected with the mains ac power supply by latch.At present, various latches are arranged on the market, these latches in use all need with hand plug to be extracted from socket, and one of its shortcoming is, if on-load is extracted or air and hand when moist, cause electric shock easily; Shortcoming two is that wired socket of laying that moves needs in the use with the hands plug to be extracted easier the electric shock.
The summary of the invention the purpose of this utility model is for increase the safe facilitating functions in the present latch technology, the latch that provides a kind of plug to eject automatically from socket.
The purpose of this utility model is achieved by following technical proposals:
A kind of power plug is made up of the socket that connects AC power and the plug two parts that connect electrical appliance, and supply socket is made of insulation shell and inner pin holding piece, and the electrical appliance plug is squeezed in by at least two pins and peripheral insulation and constituted;
In the squeezing in of described plug a block permanent magnet is set, an electromagnet is set near the pin holding piece in described socket, electromagnet and permanent magnet are set to mutually exclusive effect;
Mainly contain the switch member composition that is used to provide galvanic rectification part and is used to control work of electromagnet in the circuit of described electromagnet:
Two line ends of described solenoid circuit are reed, and two reeds are individually fixed in zero line jack and the firewire jack, and the pin holding piece in reed and the jack is an off-state; After having only pin to stretch into the pin holding piece, reed could be conducted by pin and pin holding piece, and solenoid circuit could get;
Switch in the described solenoid circuit is the switch of pyroelectric infrared transducer control and the paralleling switch of the switch composition of other form.
When using hand near socket, the infrared ray that staff discharges triggers the switch of pyroelectric infrared transducer control solenoid circuit is connected, and electromagnet gets electric work, and promotion has the plug of permanent magnet and deviates from from socket, simultaneously, solenoid circuit also is separated with alternating current circuit.
The beneficial effects of the utility model are that (1) need not the plug with the charged work of the direct pull-off of hand, thereby reduces trouble and shock hazard in using; When (2) no plug inserted state, the solenoid circuit in the socket did not have any power consumption; (3) switch in the solenoid circuit also can be set to the switch of other form as required, as remote control and fire protection etc.
Appended drawings 1 is the electric outlet structure schematic diagram;
Accompanying drawing 2 is an electrical appliance plug construction schematic diagram;
Accompanying drawing 3 is electromagnet power supply and control circuit figure;
Accompanying drawing 4 is the structural representation of attachment plug;
Among the figure: housing 1 reed 2 electromagnet 3 pin holding pieces 4
Jack 10 in switch 9 attachment plugs of pyroelectric infrared transducer control
Embodiment is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Among Fig. 1, in housing 1, pin holding piece 4 is arranged in two square holes of the electromagnet 3 that is the twoport type; Two lead-in wires of electromagnet 3 are connected to circuit board 5; The power supply circuits of electromagnet 3 are connected to reed 2 in the jack by lead-in wire in the circuit board 5.
Among Fig. 2, in the squeezing in of electrical appliance plug permanent magnet 6 is set, permanent magnet 6 insulate mutually with pin 7, and the polarity of permanent magnet 6 is under the N on the S.
Among Fig. 3, reed 2 can be introduced the 220V alternating current in the pin holding piece 4 in the circuit board 5 after pin stretches into socket, after the charging time-delay of the direct rectification of rectification part 8 and electric capacity, through switch member to electromagnet 4 power supplies.The switch 9 of wherein pyroelectric infrared transducer control moves when being set to apart from the staff 50mm left and right sides.The N of the polarity in the magnetic field that electromagnet 4 produces goes up under the S.
In use, pin is inserted moment in the socket, because the charging time of delay of electric capacity, pyroelectric infrared transducer can not worked at once, guarantee plug insert on; After having only a bit of time of delay, when staff during near infrared ray window 11, electromagnet just electronic work, plug is ejected.
Because the plug in electrical appliance does not have plug construction of the present utility model at present, is not complementary the attachment plug in available the utility model with socket of the present utility model.
Among Fig. 4, the afterbody of attachment plug is provided with jack 10, after the insertion attachment plug 10 of general plug, can with the socket of the present utility model use that matches.
Claims (3)
1, a kind of power plug, form by the socket that connects AC power and the plug two parts that connect electrical appliance, supply socket is made of insulation shell and inner pin holding piece, the electrical appliance plug is squeezed in by the insulation of two pins and periphery constitute at least, it is characterized in that, an electromagnet is set near the pin holding piece in described supply socket, in the squeezing in of described electrical appliance plug, a block permanent magnet is set, described electromagnet and permanent magnet are set to mutually exclusive effect, mainly contain the switch member composition that is used to provide galvanic rectification part and is used to control the solenoid circuit break-make in the circuit of described electromagnet.
2, power plug according to claim 1 is characterized in that, two line ends of described solenoid circuit are connected to reed, and two reeds are individually fixed in zero line jack and the firewire jack, and the pin holding piece in reed and the jack is an off-state.
