Abstract
The utility model discloses a contactor without consuming energy during operation. The utility model is used to switch on or off an electric line. The utility model comprises a coil, a mechanical self-locking device, a pressurizing spring, a returning spring, a moving contact, a static contact, an arc-extinguishing chamber, an electricity loss tripping device, a moving contact bracket and a housing. While operating, the coil does not need to be electrified. The operation of the mechanical self-locking device and the pressurizing spring connect the moving contact with the static contact; when the power-off accident occurs, the electricity loss stripping device disconnects the moving contact from the static contact.
Description
The utility model is a kind of contactor, and is particularly a kind of at when operation contactor of consume electric power not.
The magnetic core that existing contactor is overrided to form by coil, silicon steel sheet, moving contact, fixed contact, spring, arc-extinguish chamber, shell are formed.Move during coil electricity, discharge during coil blackout.Because coil must be switched on for a long time during operation, consume electric power, coiling needs more enamelled wire, and coil burns easily, influences useful life.Magnetic core is to be overrided to form with silicon steel sheet, need expend more silicon steel sheet, and processing technology is more complicated also.
Coil did not need the contactor of switching on when task of the present utility model provided a kind of the operation, and it can save electric energy and enamelled wire, increases the service life, and magnetic core has been simplified production technology without silicon steel sheet, has reduced cost.This contactor is to be used for connecting and cutting off electric wiring.
The utility model is made up of the support of coil, mechanical self-locking device, pressing spring, return spring, moving contact, fixed contact, arc-extinguish chamber, shell, dead electricity trip gear, moving contact.Mechanical self-locking device is to combine with the skeleton of coil with screw thread, fixed contact is fixed on the arc-extinguish chamber, moving contact is fixed on the support, arc-extinguish chamber is connected with screw with the skeleton of coil, the dead electricity trip gear is made up of the electronic component that is welded on the printed circuit board (PCB), be fixed on the upper end of coil rack with screw, the skeleton of shell and coil interconnects with screw, and mechanical self-locking device is made up of slide block, slide bar, cavity.
The combined floodgate running: the power supply ECDC divides the button closing coil, coil produces electromagnetic attraction, coil axes soft iron core is in the heart produced move axially, promote mechanical self-locking device, make moving contact and fixed contact closure, and finish self-locking, unclamp on-off push button, coil blackout, but under the effect of mechanical self-locking device and pressing spring, moving contact and fixed contact still keep attracting state, enter operation.
Dispose procedure: press on-off push button again, the power supply ECDC divides the button closing coil, and coil produces electromagnetic attraction once more, soft iron core is produced move axially, promote mechanical self-locking device and thread off, unclamp on-off push button, under the effect of return spring, disconnect moving contact and fixed contact.
The utility model further specifies in conjunction with the embodiments:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is a dead electricity trip gear basic circuit diagram of the present utility model.
Fig. 3 is the operation program figure of mechanical self-locking device of the present utility model.
As shown in Figure 1, the utility model is made up of the support (10) of coil (1), mechanical self-locking device (2), pressing spring (3), return spring (4), moving contact (5), fixed contact (6), arc-extinguish chamber (7), shell (8), dead electricity trip gear (9), moving contact.Mechanical self-locking device (2), be to combine with the skeleton of screw thread with coil (1), fixed contact (6) is fixed on the arc-extinguish chamber (7), moving contact (5) is fixed on the support (10), arc-extinguish chamber (7) is connected with screw with the skeleton of coil (1), dead electricity trip gear (9) is made up of the electronic component that is welded on the printed circuit board (PCB), is fixed on the upper end of coil (1) skeleton with screw, and the skeleton of shell (8) and coil (1) interconnects with screw.
Fig. 2 is the basic circuit diagram of dead electricity trip gear of the present utility model.Dead electricity trip gear (9) is that the electronic component that welds on a printed circuit board is formed, and it is installed in the upper end of the skeleton of coil (1).The utility model is to realize threading off automatically by the dead electricity trip gear when accident is cut off the power supply, and is in release condition.As shown in Figure 2, during normal power supply, to electric capacity (5) charging, controllable silicon (2) is because the collector electrode shorted to earth of triode (8) is in power supply closes through diode (4).When accident is cut off the power supply, the base potential of triode (8) reduces because of the emitter junction discharge of the voltage on the electric capacity (3) through resistance (9) and triode (8), triode (8) ends, collector potential raises, make controllable silicon (2) triggering and conducting, capacitor (5) discharges to coil (1) by normally open contact (3), the controllable silicon (2) of contactor, causes the self-locking device dropout, finishes the separating brake of major loop.When contactor was in gate-dividing state, because auxiliary contact (3) is for often opening, electric capacity (5) can pass through controllable silicon (2) and discharge to coil (1), and contactor is still kept gate-dividing state.
As shown in Figure 3, mechanical self-locking device is made up of slide block (1), slide bar (2), cavity (3).Slide block (1) and cavity (3) are the good nylon casting of anti-wear performance and form, and the upper end of slide bar (2) is a soft iron, and the lower end is that the wear resistant nylon casting is integral, and the lower end of cavity (3) is a screw thread, in the skeleton that is fixed to coil.
With reference to Fig. 3, the self-locking of mechanical self-locking device and release are finished according to following sequence of movement.
The self-locking process: coil gets by on-off push button, slide bar (2) promotes slide block (1) at the effect lower edge of coil magnetic field force axis direction and moves simultaneously, shown in Fig. 3 a, until being blocked by the lower limb of cavity (3), to lopsidedness, shown in Fig. 3 b, unclamp on-off push button, coil blackout, return spring promotes slide bar (2) and slide block (1) returns simultaneously, and slide block (1) is blocked by the top edge of cavity (3), stops slide bar (2) and slide block (1) to continue to return, shown in Fig. 3 c, reach the self-locking purpose.
Dispose procedure: coil gets by on-off push button, slide bar (2) promotes slide block (1) and moves along axis direction under the effect of coil magnetic field force, slide block (1) is blocked by the lower limb of cavity (3), tilts to opposite side, shown in Fig. 3 d, unclamp on-off push button, coil blackout is under the effect of return spring, slide bar (2) and slide block (1) return simultaneously, the location shown in Fig. 3 e, reaches the purpose of release when slide block (1) is blocked by the top edge of cavity (3).
