Description
One, technical field
The utility model relates to a kind of twin coil magnetic circuit mechanism with auxiliary contact, belongs to the contactor technical field.
Two, background technology
Along with aeronautical and space technology towards miniaturization, microminiaturization and intelligent direction develop rapidly, this just makes the space of various control system be subjected to strict restriction, the small-sized A.C. contactor that is used for whistle control system is not only required littler on overall volume, and higher requirement is arranged on bearing power.
But, be subjected to the restriction of small product size, the electromagnetic attraction that existing contactor coil can provide is limited, its impulse stroke is restricted greatly, this just causes the contact break distance of contactor contact system very little, can't guarantee between the contact when disconnecting heavy load can reliable arc extinguishing, causes the load capacity of contactor to improve, and can not satisfy the requirement that complete machine develops to miniaturization, microminiaturized direction.
Three, summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, thereby provides a kind of simple in structure, and the twin coil magnetic circuit mechanism of the band auxiliary contact of big electromagnetic attraction and impulse stroke can be provided.
A kind of twin coil magnetic circuit mechanism with auxiliary contact of the utility model, it is made up of cover plate, pull bar, moving iron core, compression spring, sleeve, actuating coil, hold-in winding, skeleton, housing, promotion dish, changing-over contact, auxiliary contact, coil lead.
Described housing is a tubular structure, actuating coil, hold-in winding and coil lead A all are arranged on the skeleton, sleeve is arranged on the skeleton inboard, be connected by cover plate between actuating coil, hold-in winding and the housing, interconnect between moving iron core, promotion dish, the pull bar three, between moving iron core and the housing compression spring is set, the conversion contact chip is connected on coil lead B, the C, on the conversion contact chip auxiliary contact is set, coil lead E, F are connected by lead with product excitation coil pin.Actuating coil one end is connected on the coil lead E, and the other end links to each other with an end and the coil lead D of hold-in winding, and the other end of hold-in winding links to each other with coil lead B, is connected by lead between coil lead C, the F.
Adopt the technique scheme beneficial effect to be:
1, simple in structure, bigger electromagnetic attraction and impulse stroke can be provided;
2, adopt twin coil magnetic circuit mechanism, starting current is big, accelerates responsiveness, the collision energy when reducing adhesive simultaneously, and can reduced volume and weight.
3, can effectively reduce coil power dissipation, reduce the coil heating amount.

Five, embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
A kind of twin coil magnetic circuit mechanism with auxiliary contact of the utility model, it is made up of cover plate 1, pull bar 2, moving iron core 3, compression spring 4, sleeve 5, actuating coil 6, hold-in winding 7, skeleton 8, housing 9, promotion dish 10, changing-over contact 11, auxiliary contact 12, coil lead A13, B14, C15, D16, E17, F18.
When applying driving voltage to coil, moving unshakable in one's determination 3 together with promotion dish 10, pull bar 2 motions, the spring 4 of compression compression simultaneously.After coil activation voltage was removed, under the effect of compression spring 4, moving unshakable in one's determination 3 returned initial position together with promotion dish 10, pull bar 2.Remove to drive the contact system of contactor by moving unshakable in one's determination 3 motion, finish the function conversion of product output interface.When initial position, the auxiliary contact 12 on the conversion contact chip 11 is with reseting ring 7 shieldings, and this moment is when applying driving voltage to coil, have only actuating coil 6 to have an effect, less because of actuating coil 6 resistances, so bigger initial electromagnetic attraction can be provided, drive moving 3 motions unshakable in one's determination.In moving unshakable in one's determination 3 processes of moving together with pull bar 2, promotion dish 10, during near the final position, promotion dish 10 promotes conversion contact chip 11, auxiliary contact 12 and coil lead A13 are disconnected, changing contact chip 11 shielding hold-in windings 7 this moment lost efficacy, actuating coil 6 and hold-in winding 7 are all had an effect, cause the coil resistance to increase, coil current reduces, electromagnetic attraction reduces immediately, but owing to 3 working clearances moving unshakable in one's determination of this moment are very little, so, the electromagnetic attraction that produce this moment is enough to drive moving unshakable in one's determination 3 and continues motion, finally reaches the final position.
