The utility model purpose just provides a kind of input terminal of micro motor and with the micro motor of this input terminal.The input terminal of this micro motor and micro motor thereof can satisfy the demand of mobile phone miniaturization, not only compact conformation, and simple installation, and the sense of shaking is big and volume is little.

The utility model provides a kind of terminal of micro motor, wherein micro motor comprises by stator, rotor, end cap portions branch and forming, stator is to be made of the magnet steel that a casing and an end are pressed in justifying in the casing afterbody, rotor is by drag cup coil, commutator and become in the other direction fixing axle with the drag cup coil and forms, and the end cap part is equipped with the groove of arrangement brush by end cap, end cap inboard and two brushes being embedded in the groove of end cap inboard are formed.The terminal of described micro motor, wherein output shaft is pressed with close-fitting pendulum.Inboard and the brush of the external part, end cap that described micro motor terminal, conduction input terminal are end caps fuses and forms, and another conduction lead-out terminal is that another brush and casing are formed by connecting, and makes motor chassis become another terminal.Wherein two brushes are arrangement in the other direction, sandwich commutator.

In the terminal of micro motor of the present utility model, this motor also has a pressing plate, and this pressing plate inboard has and the close-fitting circular arc of casing cylindrical, and the insertion tongue that this pressing plate also has a conductive plate and mates with the mobile phone preformed hole is so that fixing and installation.

Be the trapezoid cross section flange at the motor afterbody described in the utility model, can fix by corresponding groove with mobile phone.

At the end cap described in the utility model one external part is arranged, circle is embedded with one or more bearing in this external part, can guarantee motor when rotated nimbly and freely, and this external part also can be used for motor and installs and fixes.

Adopt the terminal of micro motor of the present utility model, not only make mobile phone and beeper have more good sense, and volume is little, in light weight, compact conformation rotates flexibly, is electrically connected easy, easy for installation.

By following embodiment and accompanying drawing, will help further to understand the utility model, but can not limit content of the present utility model.
