Abstract
The utility model discloses a magnetic lever open and close device which consists of a static contact, a moving contact, a static iron core, a electromagnetic coil, a tension spring, a keeper and a shell. The electromagnetic coil is interwined at one side of the static iron core. The keeper is supported at the other upper end of the static iron core with one end connected with the tension spring. The moving contact connection slice is fixed on the keeper by an insulation layer. The one end of the keeper on which the tension spring is fixed is connected with a pulling rod. The pulling rod is extended out to the shell with an insulation sleeve arranged at the outer end. A magnet which is embedded into the polar plane of the static iron core is arranged at the lower part of the keeper. The utility model is made by the lever principle. One end of the lever maintains state by the tension spring while the other end maintains state by strong magnetic force. The utility model reduces the existing trouble that the electrifying state is maintained after the main power supply (the power supply which contains its own) is cut off by the mechanical locking button or detachment button. The utility model provides the advantages of simple structure, practicality, low cost and good effect. Thus, the utility model can be used in various circuits which need to be cut off from the main power supply.
Description
Technical field
The utility model relates to a kind of switching device, relate in particular to a kind of after outage, still can keep the magnetic thick stick break-make device of electricity condition.
Background technology
Traditional automatic cutout spare, the overwhelming majority is a state when relying on mechanical lock buckle and dropout to realize still keeping electricly after it cuts off the power supply.Circuit in the modern times is advocated microminiaturization and integrated, and traditional mechanical lock buckle just seems that with dropout volume is big, and complex structure and failure rate height are difficult to safeguard.Conventional small DC control relay is made up of fixed contact, moving contact, static iron core, solenoid, armature, reset tension spring and shell.Solenoid is around U-shaped static iron core one side, armature is supported on static iron core other end upper end, moving contact is fixed on the armature by insulating barrier in flakes, armature is supported on and plays a leverage on the static iron core, getting effect armature one end face and static iron core pole-face closure that electromagnetism electric coil arranged of electric back by electromagnetic force, be pulled to reset condition owing to the armature other end is equipped with reset tension spring after the dead electricity, thereby drive the disconnection and closure of moving contact and fixed contact.
Summary of the invention
The purpose of this utility model is: remedy the deficiency of prior art, a kind of magnetic thick stick break-make device with on-off function is provided.
The utility model is realized by following scheme: be made up of fixed contact, moving contact, static iron core, solenoid, extension spring, armature and shell.Solenoid is around static iron core one side, and armature is supported on static iron core other end upper end, an end linking tension spring, and moving contact is fixed on the armature by insulating barrier in flakes, and an armature fixedly end of extension spring connects a dead man, and extends shell.
The utility model is also set up a magnet below armature.
Magnet described in the utility model embeds the pole-face of static iron core.
Insulating case is equipped with in the utility model dead man outer end.
The utility model utilizes the lever stress principle to be made, one end utilizes the extension spring hold mode, the other end relies on strong magnetic force to keep state, it has reduced existing dependence mechanical lock buckle or has threaded off and to realize cutting off the trouble of state when still keeping electricly behind the main power source (promptly containing its own power source), simple in structure, practical, cost is low, effective, be applicable to the circuit of all kinds of required disconnection main power sources.

Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is made up of fixed contact 1, moving contact 2, static iron core 3, solenoid 4, extension spring 5, armature 6, dead man 7, magnet 8 and shell 10.Solenoid 4 is around static iron core 3 one sides, and armature 6 is supported on static iron core 3 other ends upper end, an end linking tension spring 5, moving contact 2 is fixed on the armature 6 by insulating barrier in flakes, armature 6 a fixedly end of extension spring connects a dead man 7, and extends shell, and insulating case 9 is equipped with in the outer end.Magnet 8 is arranged on armature 6 belows, and embeds static iron core 3 pole-faces.Dead man 7 can make fixed contact disconnect under external force and be closed, thereby realizes electronic combine moving with being subjected to external force.
