Problems solved by technology
[0003] With the improvement of everyone's quality of life, the market defect rate of products in the smart home field is very high. The defect rate of the current claw pole stepping motor has been controlled at about 10PPM, but it still cannot meet the more stringent requirements of special customers. They even pursue zero bad
One of the defects that may occur in the claw pole stepper motor is the displacement of the terminal pins

Abstract
The invention provides a stator framework assembly and a stepping motor comprising the same. The stator framework assembly comprises a framework and a terminal block, wherein the framework provides a winding space with a central axis for winding a wire and a rotor cavity; the terminal block is provided with a terminal block body protruding from one end wall of the framework in the central axis direction, and the terminal block body is provided with a first side surface facing the rotor cavity, a second side surface deviating from the rotor cavity and a plurality of pin holes extending between the first side surface and the second side surface and used for installing terminal pins; and the length of a matching section, which is used for being matched with the terminal pin, of the pin hole is 2-9 times of the aperture of the pin hole. The matching length of the pin holes can still meet the requirement for the anti-drawing force of the terminal pins at a high temperature, the anti-drawing force between the terminal pins and the terminal block can be well kept in a space with a limited size, the terminal pins are prevented from displacement under the action of external force, and the pulling-out force of the terminal pins is improved.
Description
technical field [0001] Embodiments of the present disclosure relate to a stator frame assembly and a stepping motor including such a stator frame assembly. Background technique [0002] Claw pole stepper motors are widely used in the field of smart home. A claw-pole stepper motor may include a casing and a stator assembly, a rotor assembly, and a gear assembly installed inside the casing. The stator assembly includes a stator skeleton assembly, a first corresponding pole plate with a plurality of first corresponding pole claws, and a second corresponding pole plate with a plurality of second corresponding pole claws. The stator frame assembly includes a first frame portion, a first pole plate having a plurality of first pole claws that cooperate with a plurality of first corresponding pole claws, a plurality of second pole claws that cooperate with a plurality of second corresponding pole claws The second pole plate and the second skeleton part. [0003] With the improvem...
