Description
Technical field
The utility model relates to relay field, especially relates to magnetic latching relay.
Background technology
Magnetic latching relay is a kind of new type of relay grown up in recent years, is also a kind of automatic switch.The same with other electromagnetic relays, circuit is played and automatically connects and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect relying on permanent-magnet steel completely, and the conversion of its on off state leans on the pulse electrical signal of one fixed width to trigger.
Magnetic latching relay is divided into single-phase and three-phase.According to interrelated data introduction, the contact switching current of magnetic latching relay is in the market maximum reaches 150A; Control coil voltage is divided into DC9V, DC12V etc.General appliance life 10000 times; Mechanical endurance 1000000 times; Contact pressure drop <100mV.Therefore, there is power saving, stable performance, volume is little, bearing capacity is large, than the feature of general electromagnetic relay superior performance.
The magnetic force that its contact opening and closing state of magnetic latching relay is produced by permanent magnet at ordinary times kept.When the contact of relay needs open or close state, only need to use just (instead) DC pulse voltage excitation coil, relay just completed out and the State Transferring closed in moment.When usual contact is in hold mode, coil does not need to continue energising, only just can maintain the state of relay by the magnetic force of permanent magnet constant.
But, so just necessarily require armature and contact to be positioned at same interval, and closely arrange each other.So just limit the trend of relay microminiaturization.The capacity issue of magnetic latching relay has limited the development of high precise equipment.
Summary of the invention
Under task of the present utility model is to provide a kind of volume, the magnetic latching relay of compact conformation.It comprises: a pedestal, a coil, and described coil is arranged within described pedestal.One armature, described armature is positioned at the side of pedestal interior loop, and described armature can rotate around self.At least two braces, described two braces are respectively brace one and brace two, together with described brace one is fixedly installed with described pedestal.One end that described brace one is positioned at pedestal is fixedly installed fixed contact.Together with described brace two is fixedly installed with described pedestal, and one end that described brace two is positioned at pedestal is fixedly connected with reed.The other end of described reed is provided with the moving contact contacted with described fixed contact.The one end described reed being arranged moving contact is also connected with pushing piece, active link between described pushing piece and described turning handle.
Further be improved to, the described pushing piece region corresponding with described turning handle is provided with groove, and one end of described turning handle is placed in described groove.
Further be improved to, described coil can produce can counter field.
Further be improved to, described armature side is provided with the cover plate of fixing described armature.
Further be improved to, the bottom of described pedestal is provided with through hole.
Further be improved to, described pedestal is provided with fixing hole.
Utilize the lever principle between pushing piece and the turning handle of armature like this, the rotation that coil drive armature produces can be converted to the translation of pushing piece.Then pass motion to reed by pushing piece, thus realize closing down and closed procedure whole circuit.Therefore, the volume of whole device can effectively control as required.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of each component involved in embodiment of the present utility model, structure, each several part and annexation, each several part and operation principle etc. are described in further detail.
Magnetic latching relay as shown in Figure 1, 2, comprises pedestal 10 in the present embodiment, is provided with reversible magnetic coil 20 in pedestal 10.The side of coil 20 is provided with armature 30, and the center of this armature 30 is provided with rotating shaft 34, and when magnetic coil 20 pairs of armature 30 generation effects, armature 30 can rotate around this rotating shaft 34 like this.Armature 30 is also provided with turning handle 32.At stable move in plane when rotating to enable armature 30, so be provided with cover plate 70 on armature 30 top.
In pedestal 10, be also provided with two braces be connected with external circuitry 40, wherein brace 1 and pedestal 10 are fixed together, and the lamellar body being positioned at pedestal 10 at this brace 1 is provided with the fixed contact 422 for conducting electricity.The lamellar body that brace 2 44 is positioned at pedestal 10 is fixedly connected with reed 50, one end of reed 50 is fixedly installed the moving contact 52 contacted with fixed contact 422.In order to fixed contact 422 and moving contact 52 are easy to clutch, in the present embodiment frustum cone structure is arranged in two contacts.
As shown in Figure 3, one end that reed 50 arranges moving contact 52 is also connected with pushing piece 60, and this pushing piece 60 extends to the region at turning handle 32 place on armature 30.On this pushing piece 60, the position corresponding with turning handle 32 is provided with groove 62, and one end of turning handle 32 is just placed in this groove 62.The rotational kinetic energy of self can be converted to the rectilinear motion kinetic energy of pushing piece 60 like this when turning handle 32 rotates, thus realize the clutch being controlled moving contact 52 and fixed contact 422 by the rotation of armature 30.
For the ease of observing the working condition of fixed contact 422 and moving contact 52 when relay works, stationary contact 422 and the bottom of the pedestal 10 at moving contact 52 place are provided with through hole 12.Magnetic latching relay is bolted to connection, so be provided with some for fixing hole 14 on pedestal 10.
