Description
Technical field
The utility model relates to a kind of circuit, electrical equipment automatic switch element, is widely used in all kinds of electric power, electronics, electromechanical equipment etc.
Background technology
Relay is the automatic switch element of indispensable isolation features such as all kinds of electric power, electronics, electromechanical equipment.Now, what use in relevant technologies, the equipment is Morse's formula electromagnetic relay, by paint tame Morse invention and patented in 1873 of the U.S., at first is successfully applied in the telegraph by his invention.Since 132 years, Morse's formula electromagnetic relay is used till today always, though people propose many improvement to it, its structure does not have essence and changes.As since 1985, in about 150 of the patent that China applies for relevant Morse's formula electromagnetic relay, their structure is generally formed (Fig. 1) by L type metal holder, iron core, inductance coil, armature block, elastic spring, spring, quiet spring contact blade, base, shell.Morse's formula electromagnetic relay major defect is: volume is big; The inductance coil power consumption is many; The eddy current that easily produces unshakable in one's determination has magnetic hysteresis loss; Voltage instability regularly often causes its electromagnetic core adhesive armature piece unreal and produce spark, and burn moving contact and fixed contact etc. shorten electromagnetic relay useful life; Armature block is during by the electromagnetic core adhesive, and annoying noise is sent in armature block and electromagnetic core collision.
I have applied for " the general magneto electric relay of energy-saving no-noise " patent on January 24th, 2005, and application number is 200520050171.1 (Fig. 2).In this structure, there are not L type metal holder, iron core, armature block, critical component is to fixedly mount magnet on the moving contact on the spiral inductance coil one end opposite of no iron core, behind input dc power on the spiral inductance coil of no iron core, the end facing to magnet at coil produces and the magnetic pole of magnet facing to the intrinsic magnetic pole same polarity of an end of coil, like pole produces repulsive force, the moving contact that promotes relay contacts with fixed contact, the circuit of being controlled is opened or closed, and this structure can be described as " repulsion formula ".Though this structure is more simple in structure than Morse's formula electromagnetic relay, but complicated, particularly moving contact is subjected to repulsive force and the repulsion that produces promotes, and the sticking pulling that produces not as being subjected to attraction is sensitive, quick.
Summary of the invention
The purpose of this utility model be to release a kind of not only simple in structure than Morse's formula electromagnetic relay, performance good, and than I the design " the general magneto electric relay of energy-saving no-noise " simple in structure, the general magneto electric relay of the better energy-conservation sucked type of performance.
The technical solution of the utility model is: in the fastening mounting seat in insulation crust bottom, in the inner chamber of shell and base formation, helical form inductance coil, helical form inductance coil reference column, movable contact spring, magnet, movable contact spring contact, static contact spring piece, static contact spring piece contact, helical form inductance coil binding post are installed.Do not have iron core in the helical form inductance coil, an end of helical form inductance coil reference column is fastened on the base, and the helical form inductance coil is fastened on outside the helical form inductance coil reference column around cover, makes that the helical form inductance coil is unlikely to be moved or swing along its axis.Movable contact spring is L-shaped, and parallel and this end of the axle of L shaped one side and helical form inductance coil is fastened on the base, and L shaped another side passes the top of helical form inductance coil upper end and relative with the upper end of helical form inductance coil.Magnet be fastened on movable contact spring with helical form inductance coil upper end opposing L shape on one side on.The movable contact spring contact be fastened on movable contact spring with opposing L shape termination on one side, helical form inductance coil upper end.The lower end of static contact spring piece is fastened on the base, and its upper end is fastening with the static contact spring piece contact and corresponding up and down with the movable contact spring contact position.One end of helical form inductance coil binding post is connected with the termination conduction of helical form inductance coil respectively, and the other end and base are fastenedly connected.During helical form inductance coil input dc power, produce and the magnetic pole of magnet facing to the intrinsic magnetic pole opposite polarity of helical form inductance coil one end at the end of helical form inductance coil facing to magnet.Produce attraction between opposite pole, spur movable contact spring of the present utility model and on moving contact contact with the static contact spring piece contact, the circuit of being controlled is opened or closed." sucked type " of the present utility model, the spiral inductance coil that does not have iron core when promptly connecting direct current is inhaled a kind of like this structure that the pulling spring strip contact contacts with the static contact spring piece contact with the attraction that the opposite pole of opposite end of magnet on being fastened on movable contact spring produces.
The general magneto electric relay advantage of energy-conservation sucked type that the utility model is released is outstanding: the running status that can control big electric current, high-tension electromechanical equipment; The design does not have iron core and armature block owing to there is not L type metal holder, thereby consumptive material is few when making, and can save a large amount of nonferrous materialss; Volume is little, and is in light weight, than minimum in the world by the logical FTR-P that produces of the rich soil of Japan up to now
6(it is also little to be of a size of 9 * 12 * 10.3mm) volume, and weight is also light for type 20A Morse formula electromagnetic relay; Fault is few during work, and a deciliter action is once finished, and is quick, can not send annoying noise; Purposes is wide, is widely used in the remote-control romote-sensing in each class of electronic devices in sea, land and sky, various civilian military vehicles, household electrical appliance, all kinds of electromechanical integration and electric power, electronic equipment, wired electricity, wireless all kinds of stored-program control exchanges.
What deserves to be mentioned is that " sucked type " that the utility model is released is sensitiveer, faster, more reliable than (application number 2,005 2,005 0171.1) " repulsion formula " deciliter action that I applied on January 24th, 2005.One of reason, the repulsive force in " repulsion formula " sharply reduces along with distance between the dynamic and static contact increases, and therefore requires the tripping force of repulsion big, and the distance between the dynamic and static contact is little.And attraction close along with distance between the dynamic and static contact in " sucked type ", attraction is big by square multiplication of distance, and therefore, the tripping force of attraction can be smaller, and the distance between dynamic and static contact can be greatly.Two of reason, attraction that produces in " sucked type " and " repulsion formula " the middle repulsive force that produces say that strictly size is not wait.When the helical form inductance coil is switched on, produce magnetic field, regard a kind of magnetizing mediums as if will be positioned at the magnet on helical form inductance coil one end opposite, under the effect of coil magnetic field, also can magnetize (this claims magnetizing field).In " repulsion formula " structure, magnetizing field has offseted the intrinsic magnetic field of a part of magnet, and in " sucked type " structure, the intrinsic magnetic field of magnetizing field and magnet is superimposed, thereby under the identical situation of relevant condition, the absolute value of the repulsive force that " repulsion formula " produces is littler than the absolute value of the attraction that " sucked type " produces.Attraction is greater than repulsive force, and the action of the sticking of generation is sensitiveer, quick, reliable than repelling the action nature.
