Technical Field

[0001] The utility model relates to the technical field of micro motors, and particularly relates to a stator wire frame structure of a micro motor. Background Technique

[0002] A pin is a conductive connector for transmitting electrical signals, and a stator is a component in a brushless motor for generating a rotating magnetic field. The existing micro motor stator includes a base, a stator core, a coil, and pins for transmitting electrical signals to the coil. Multiple pins are inserted and installed on the stator core, and the coil is energized due to the transmission of electrical signals by the pins, thereby generating a rotating magnetic field and operating normally.

[0003] Currently, most wire frames used on motors are provided with hollow cylinders for the insertion and positioning of pins. However, due to the insufficient space of the external tooth structure of the micro motor, the protruding hollow cylinders occupy space, which is not conducive to the assembly and welding operations of the wire frame and the circuit board.

[0007] Further, a plurality of equally spaced slots are opened on the wire frame body, an avoidance groove is opened at the upper end of the wire frame body, and a positioning hole is opened in the avoidance groove.

[0008] Further, a limiting column is arranged in the slot, and there is a certain gap between both sides of the limiting column and the slot.

[0009] Further, the positioning hole penetrates through the limiting column, and the lower end of the winding wire pin is located in the positioning hole.

[0010] Further, the inner ring body is embedded in the slot.

[0011] Further, one end of the outer ring body close to the limiting column is in interference fit with the slot and the limiting column.
