Description
Technical field
The utility model relates to auto parts machinery field, is specifically a kind of light modulating device stepping motor.
Background technology
Along with the development of automobile safety lighting technology, the application of the Intelligent Light-control System of automobile is more and more extensive, particularly be applied to the stepping light modulating device of automobile front lamp, this stepping light modulating device adopts stepping motor to drive the mode of bulb push rod, rotatablely moving of stepping motor converted to the rectilinear motion of bulb push rod, so just can control by control step motor the rectilinear motion of bulb push rod, thereby adjust the lighting angle of car headlamp.
Stepping motor in automobile light-modulating device is mainly the power section as light modulating device, receives the pulse control signal of controller, and provides by output shaft output is provided.The light modulating device of prior art is to draw from stator coil with the general binding post of stepping motor; solder joint is generally located on the skeleton of stator coil; the connector of stepping motor often departs from binding post because the drawing of wire harness causes lead-in wire like this; thereby cause motor coil to lose efficacy; also often there will be the connector of stepping motor or rocking of connector fixing seat and cause lead-in wire to depart from; or the terminal sealing-off of connector sealing-off or coil; cause motor to lose efficacy, thereby this light modulating device is poor by reliability and the vibration strength of stepping motor.
Utility model content
Technical problem to be solved in the utility model is, overcome the defect of prior art, and the light modulating device stepping motor that a kind of vibration strength and reliability are higher is provided.
For solving the problems of the technologies described above, the utility model proposes a kind of light modulating device stepping motor, it comprises shell, end cap, rotor and stator, described stator comprises two stator skeletons, described each stator skeleton is provided with terminal, described terminal and stator skeleton are injection molded into one, on described shell, have connector fixing seat installing port, on described connector fixing seat installing port, connector fixing seat is installed, described wiring board and connector are located on connector fixing seat, and described terminal is electrically connected with wiring board through connector fixing seat.
Adopt this structure, the lead-in wire of stator coil can with terminal soldering, and terminal is inserted in the circuit board by connector fixing seat and is electrically connected with wiring board, between terminal and wiring board, do not adopt like this lead-in wire to be connected, the solder joint place of terminal does not stress, this solder joint is just not easy sealing-off and loosening, thereby the vibration strength of stepping motor and reliability are higher.
Described connector fixing seat is provided with reference column, and described end cap is provided with the location hole coordinating with this reference column.Adopt this structure to position by reference column and location hole in the time that connector fixing seat is installed, prevent that connector fixing seat from rocking and coming off.
Described shell is provided with the T-shaped connector that a large handle is little, and described connector fixing seat is provided with the circular groove with rectangular opening, and described T-shaped connector coordinates with this circular groove.Adopt the T-shaped connector of this structure can be through the rectangular opening on connector fixing seat, then connector fixing seat rotates an angle again and just connector fixing seat is stuck on shell, prevents that connector fixing seat from coming off from shell.
Described connector fixing seat is provided with the slot for inserting wiring board, and described wiring board inserts in this slot, and the terminal on described stator skeleton inserts the connecting hole in wiring board and welds with wiring board, and described connector welds in the circuit board.Adopt this structure, wiring board is inserted in slot, can bear compared with large pulling capacity and not come off from connector fixing seat.
