Description of drawings
Fig. 1 is a full section structural representation of the present utility model:
Fig. 2 is a main TV structure schematic diagram of the present utility model;
Fig. 3 is a Side TV structure schematic diagram of the present utility model;
Embodiment:
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model partly is made up of contact part, electromagnetic mechanism.Contact partly comprises bridge-shaped contact 3 and fixed contact 4.Bridge-shaped contact 3 is pressed in by spring 2 in the gathering sill of contact supporter 1 and is kept in motion; Fixed contact 4 is by the contact plate nut 7 of bolt shape, and spring washer 5 and pad 6 are fastened on the arc control device of pedestal 10.Bridge-shaped contact and fixed contact constitute an one pole tributary open and close circuit.
Electromagnetic mechanism partly adopts the clapper-type magnetic circuit, and magnetic is gripped 16 bottoms and is fixed in the circular hole of coil 12 unshakable in one's determination 11 with bolt 13 and spring washer 15, and magnetic is gripped 16 and unshakable in one's determination 11 and constituted the magnetic circuit of a closure at the armature 8 of contact supporter 1 bottom with riveted.Connect voltage suppressor 20 between two terminals 14 of coil 12.Voltage suppressor 20 comprises current-limiting resistance 23 and fly-wheel diode 24.
Novel part of the present utility model is:
1, this contactor adopts the optimized integral structure design: with three parts independently on the original structure, the pedestal of negative, dress contact is installed and is rolled the skeleton of coil, be combined as a very simple plastic structural part of structure through after the optimal design, product structure number of packages amount is reduced to minimum.
2, adopt the structure of contact terminal of clapper-type double break point, make opening apart from increasing of contact, thereby help the elongation of electric arc and extinguish, increased the functional reliability under the condition of work of flowing automatically.
3, use the attraction principle of pole pair electric arc, mount permanent magnet, dwindled clearance between open contacts effectively, contact physical dimension is partly greatly reduced in the contact both sides.
4, at the coil two ends and connect voltage suppressor, the self-induction electromotive force that coil is produced when outage discharges by resistance and diode, suppressed the self-induction electromotive force effectively, the release delay time of D.C. contactor is shortened, be beneficial to the reliable of contactor and disconnect fast.
5, on the installation bottom surface, added one and be applicable to the annex that is installed in the wide standard mounting rail of 35mm, made installation of this product and dismounting easier, quick.
This one pole D.C. contactor novel structure, reliable in action, volume are little, in light weight, and its electric property, vibration resistance, fire resistance, temperature characterisitic have have all met or exceeded the requirement of railway electrical equipment standard techniques.On the available iron road vehicles, also can be used for electric power, hand in transportation advanced in years, the industrial automation control system.
The main circuit of the utility model product is inserted by+1 termination through contact stud 4, is switched on or switched off through bridge-shaped contact 3, via the output of 2-termination, thereby has controlled the conducting of main circuit or opens circuit.The control signal of telecommunication is entered by the A1 end through lug plate (] 4, and coils 12 backs are flowed out by the A2 end, determine this contactor to be in work or halted state by the control signal of telecommunication.
Operating state of the present utility model is when the signal of telecommunication enters coil 12 through being held by A1, produce magnetic field behind the coil electricity, the magnetic line of force in this magnetic field is through yoke 16, iron core 11 and armature 8 backs form the magnetic circuit of a sealing, under the attraction of magnetic force, after armature 8 overcame the elastic force of antagonistic spring 9, armature drove contact supporter 1 and moves in closure to 11 end faces unshakable in one's determination, has finished the closing course of magnetic circuit.Under the pulling of armature, contact supporter 1 moves until closed fully with fixed contact to the direction of fixed contact 4 with the bridge-shaped contact 3 that is installed in its gathering sill.This moment, this contactor was in running order, made the electric current of main circuit through+1 end, flow to bridge type contact 3, flowed out through the 2-termination after flowing to fixed contact 4 again, had realized the connection of main circuit.When the signal of telecommunication in the control circuit is cancelled, in the circuit of circle 12 of pulling strings via lug plate 14, there is not the electric current process, the magnetic field in the coil disappears, and via yoke 16, the magnetic line of force of iron core 11 and armature 8 has not existed yet.Owing to there is not the attraction of magnetic force, under the counter elastic force of making spring 9, armature pops up; Under the drive of armature, contact supporter 1 also moves upward thereupon, the drive of contact supporter 1 it, the bridge type contact also pops up, and has broken away to cross fixed contact 4, when disconnecting, produced electric fox between the dynamic and static contact, electric arc outwards moves among two cavitys of arc control device 18 rapidly under the action of a magnetic field of permanent magnet 21, in air the cooling and extinguish, finished the disconnection process of main circuit, this contactor was in and stopped the shape thought this moment.The signal of telecommunication disappears in control circuit, during coil blackout, to produce very high-tension self-induction electromotive force at coil two ends, this electromotive force discharges by resistance on the voltage suppressor and diode, effectively suppressed the self-induction electromotive force, and the release delay time of D.C. contactor is shortened dramatically, make this contactor to disconnect fast.
