A connecting rod is connected with the permanent-magnet armature and is connected with a moving contact through a contact spring. A static contact is fixed on the casing. The contactor of the utility model is suitable for automatically controlling and remotely controlling a distribution circuit, a lighting circuit, a domestic appliance, etc. Electricity is saved. The utility model has the advantages of safety and simple structure without noise and can not be influenced by the voltage of an electric network.
Description
The utility model relates to a kind of magneto energy-saving contactor that is used for switching on or off frequently or chronically the control circuit of load-carrying main circuit and large and small capacity.
At present, all kinds of electric equipments, electronic instrument, household electrical appliance etc. all develop towards automation direction, but because present power supply shortage, power supply quality is poor, make existing AC and DC contactor be subjected to serious threat, mainly show as: 1. be subjected to the influence of line voltage big, when voltage was higher than rated voltage, the heating of the magnet exciting coil of contactor was serious, burn easily, when voltage is lower than rated voltage, the contactor starting difficulty, contact has the loose contact phenomenon, easy scaling loss contact, even melting welding, make the contact can't disjunction, very easily cause the accident.2. power consumption is bigger, and its power consumption of particularly large-scale contactor is quite big.3. the mechanical moving part when contactor is stuck, and when making the iron core adhesive bad, also easily burns coil.4. frequency of operation is low.5. be easy to produce electromagnetic noise.
The purpose of this utility model is the contactor of a kind of dc powered of design, it is can be energy-conservation, be not subjected to the influence of grid voltage change during work, not power consumption during operation, driving power is little, does not produce electromagnetic noise, can improve frequency of operation, life-span simple in structure, that coil uses is long, even mechanical part is out of order, also can not burn coil.Be difficult for taking place the magneto energy-saving contactor of any accident, it is suitable for need not after the power supply decompression circuit of trip-free, have in the circuit of stand-by power supply power supply and the battery powered circuit and do control and remote control automatically, as distribution line, lighting circuit, electronic circuit and household electrical appliance etc.
Technical solution of the present utility model is, a DC electromagnet that is made of iron core and magnet exciting coil directly is fixed on above the base of the shell of being made by insulating material, another is embedded the keeper of forming in the groove of armature by an annular permanent magnnet, because keeper has big gap between closure head and DC electromagnet, so keeper is to do upper and lower motion.Retracting spring is installed between DC electromagnet and the keeper, when magnet exciting coil does not feed electric current, the no magnetic field of DC electromagnet itself, gap maximum between keeper and the DC electromagnet, keeper is to the attraction of the DC electromagnet reaction force less than retracting spring, keeper is released the spring top upwards, and DC electromagnet and keeper were in and left the position this moment.When in magnet exciting coil, feeding the DC driven electric current, DC electromagnet just produces the magnetic field of a fixed polarity, when at this moment if the polarity of the polarity in this magnetic field and keeper is just in time different, produce attraction between keeper and the DC electromagnet, this attraction is the reaction force that is far longer than retracting spring, so keeper moves downward, until with the adhesive of direct solenoid iron phase.Connecting rod and armature link, and connecting rod is to make with insulating material, and connecting rod connects by touch spring and moving contact, and fixed contact is to be fixed on the shell.When DC electromagnet attracts keeper to move downward, just drivening rod, connecting rod drive touch spring to keeper simultaneously, it is downward that touch spring drives moving contact, and when keeper and DC driven electromagnetic actuation, moving contact and fixed contact also are in the close position.Disconnect the electric current in the magnet exciting coil, because the gap minimum between keeper and the DC electromagnet at this moment, although DC electromagnet has not produced magnetic field because of no current by itself, but keeper to the attraction of DC electromagnet still greater than the reaction force of retracting spring, so continue to keep attracting state, the contact of contactor also is in closure state.When making magnet exciting coil feed reverse DC driven electric current by change over switch, to produce a fixed magnetic field in the DC electromagnet, the DC electromagnet polarity of the magnetic field of this moment is identical with the keeper polarity of the magnetic field, just produce a thrust, add the active force of retracting spring, make keeper drivening rod, connecting rod drive touch spring, touch spring drives moving contact and moves upward together, and moving contact and fixed contact leave.Dynamic and static contact can be made Chang Kai or normally closed contact and required number according to the needs of circuit.
The utility model has the advantages that: the magneto energy-saving contactor needs except starting with when stopping to feed the direct current drive current in magnet exciting coil, all the other are in service to be not loss electric energy, so it is a kind of energy-conservation control apparatus, simple in structure in addition, it is difficult that there was a mechanical failure, the generation mechanical breakdown even be in operation, the accident that also can not burn magnet exciting coil.Because its coil does not have electric current to pass through in the middle of the operation, avoided the high and low and influence that causes of line voltage, also therefore can improve the frequency of operation of contactor.Do not have noise in the middle of the operation in addition, coil and contact life-span are long.
Below in conjunction with accompanying drawing in detail embodiment is described in detail.
The magneto energy-saving contactor has a DC electromagnet that is made of iron core (1) and magnet exciting coil (2), DC electromagnet is fixed on the base of the shell made from insulating material (10), other has in the groove that is embedded armature (4) by an annular permanent magnnet (3) and the keeper that constitutes, and keeper can be done upper and lower motion.Retracting spring (5) is installed between DC electromagnet and the keeper, connecting rod (6) is to make with insulating material, it connects with keeper, and by touch spring (9) and moving contact (7) connection, fixed contact (8) is fixed on the shell (10), and dynamic/static contact also can be made Chang Kai or normally closed interlock and required number according to the needs of circuit.
The service position of living in of contactor shown in the accompanying drawing is the magnet exciting coil (2) of contactor when not feeding electric current, and DC electromagnet and keeper leave, and dynamic and static contact is in the disjunction position, and at this moment retracting spring (5) is with position upwards, keeper top.When in magnet exciting coil (2), feeding the DC driven electric current, DC electromagnet just produces the magnetic field of a fixed polarity, if the polarity of the polarity in this magnetic field and keeper is polarity chron shown in the drawings, this attraction is greater than the reaction force of retracting spring (5), so keeper drivening rod (6), connecting rod (6) drives touch spring (9), touch spring (9) drives moving contact (7) and moves downward, when keeper and the adhesive of direct solenoid iron phase, moving contact (7) also is in the close position with fixed contact (8).Disconnect the electric current in the magnet exciting coil (2), this moment keeper to the attraction of DC electromagnet still greater than the reaction force of retracting spring (5), so continue to keep attracting state, the moving contact of contactor (7) also is in closure state with fixed contact (8).When making magnet exciting coil (2) feed reverse direct current by change over switch, DC electromagnet will produce a fixed magnetic field, opposite in polarity and the accompanying drawing shown in the iron core (1), make the magnetic field in this magnetic field and the keeper produce a thrust, add the active force of retracting spring (5), make keeper drive moving contact (7) and move upward together, contactor separates reinstatement.
