Abstract
A contacting device without electrical energy consumption during the running process. An electro-magnet, a supporting frame, a spring, and an armature iron are arranged at the upper part of the contacting device, an interlocking rod is fixed on a moving iron core, the armature iron is connected on the supporting frame in a swinging way, a draught spring is connected on the armature iron and the supporting frame, the interlocking rod is fixed with the moving iron core, and the electro-magnet is fixed in the outer casing. The contacting device only consumes electrical energy during the starting and stopping process, no electrical energy is consumed during the running process, and the armature iron blocks the interlocking rod fixed on the moving iron core to enable the moving iron core not to return after the contacting device coil is powered off, to contain the normal running of the contacting device.
Description
Affiliated technical field
The utility model relates to contactor in the distribution field.
Background technology
Present known contactor is to utilize electromagnetic attraction, and the operation of interlock contact mechanical action control apparatus produces magnetic force to coil power supply and could guarantee normal operation, and its magnetic force systems wants consumed power to cause waste of electric energy.
Summary of the invention
In order to overcome the deficiency of existing contactor consumed power in running, the utility model provides a kind of coil consumed power when starting and stopping, the contactor of consumed power not in running.
The technical scheme that its technical problem that solves the utility model adopts is at contactor top installing electromagnet, tension spring, support, armature and is fixed on the trace that moves on the iron core.Armature is connected on the support and can swings.Tension spring one end is fixed on that the other end is fixed on the support on the armature.Electromagnet is fixing in the enclosure.After the contactor electromagnet energising, produce magnetic force, moving iron core and static iron core adhesive, the trace servo-actuated iron core that is fixed on the moving iron core moves down, and when moving to the lower end, the armature lower end is adjusted screw when swinging to trace top and stops, stops swinging.When trace moves up under the drive of moving iron core behind the coil losing electricity, stopped, can not return by armature.Dynamic/static contact can not be separated, and circuit can not be cut off electrical equipment and normally move.When electrical appliance need stop, after the energising of top electromagnet, to electromagnet one side oscillation, leave trace top at electromagnetic force effect lower armature, moving iron core reposition, electrical appliance stops.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is a contactor example structure schematic diagram
In the accompanying drawing 1, armature 2, adjust screw 3, tension spring 4, support 5, shell 6, electromagnet 7, trace 8, housing 9, moving iron core 10, thrust spring 11, coil 12, static iron core
Embodiment
Armature (1) is connected with support (4) in the accompanying drawings, armature (1) can be by a small margin swing, tension spring (3) one ends are connected the last other end of armature (1) and are connected on the support, electromagnet (6) is fixing in the enclosure, adjust screw (2) and be connected on the shell (5) by internal thread, screw (2) is adjusted in rotation can adjust the amplitude of fluctuation of armature (1) to trace (7).Below in conjunction with accompanying drawing the utility model embodiment is further specified
After coil (11) energising, producing electromagnetic attraction makes (9) unshakable in one's determination drive moving contact and the closed main circuit of connecting of fixed contact, the trace (7) that is fixed on simultaneously on moving (9) unshakable in one's determination moves down under the drive of moving iron core, armature (1) lower end loses and stops to be adjusted to trace (7) side oscillation and stop after screw (2) stops, after coil (11) outage, the electromagnetic force of coil (11) disappears, under thrust spring (10) effect, moving iron core (9) moves up, trace (7) upper end is withstood by armature (1) lower end, dynamic/static contact can not separate, and main circuit continues to connect.Electromagnet in the time will cutting off main circuit (6) energising produces electromagnetic attraction, and armature (1) to electromagnet (6) one side oscillations, breaks away from trace (7) top under the electromagnetic attraction effect.Trace (7) loses and stops, moving iron core (9) drives moving contact under the effect of thrust spring (10) separates with fixed contact, and main circuit is cut off.
Claims (3)
1. contactor, moving iron core (9), static iron core (12), coil (11), thrust spring (10) are housed in the insulation shell, it is characterized in that: electromagnet (6), tension spring (3), support (4), armature (1) are equipped with in contactor top, armature (1) is connected on the support (4) and can swings, tension spring (3) one ends are connected the last other end of armature (1) and are connected on the support (4), electromagnet (6) is fixed in the shell (5), and trace (7) is fixed on the moving iron core (9).
2. according to claims 1 described contactor, it is characterized in that: armature (1) is connected with pin with support (4).
3. according to claims 1 described contactor, it is characterized in that: armature (1) is plugged on support (4).
