Description
The present invention relates to a step motor actuator device, and more particularly, to a step motor actuator device having a structure for stably fixing a substrate.
Generally, an actuator of a vehicle air conditioning apparatus is used as means for driving and controlling the opening and closing of a damper which is an air flow opening and closing means provided in an air conditioner of a vehicle.
Such a damper has three dampers according to a direction (position) mode in which the damper is discharged into the vehicle, an outside air inflow and outflow mode, and a cold and warm setting mode, and the actuator is driven according to the user's setting, Is controlled.
As described above, the actuator applied to the air conditioner for a vehicle is composed of a motor having a connector.
A PCB having a control function is disposed between the connector and the motor and is electrically connected to the connector and the motor.
In the past, a method of providing a separate PC Guide was used to fix the PC.
However, such a method has a problem that the manufacturing cost is increased and the number of air is increased due to the addition of a separate PCB guide.
In addition, in order to solve the above-mentioned problems, a method of integrally forming a connector housing with a guide is not provided.
However, since insert injection molding is integrally performed with the terminal provided in the connector housing, the manufacturing cost is increased and the size of the PCB is relatively increased.
An object of the present invention is to provide a step motor actuator device capable of stably fixing an assembly position of a substrate by using a yoke included in a motor portion.
It is another object of the present invention to provide a step motor actuator device capable of eliminating a separate guide part for guiding the fixing of a conventional substrate, thereby improving the assembling property and reducing the cost of air.
According to a preferred aspect of the present invention, there is provided a motor cover comprising: a motor cover; a motor portion having a yoke formed inside the motor cover and having a fixing portion protruded outward so as to fix the edge of the substrate across; And a connector portion coupled to the motor portion to fix the end portion of the fixing portion.
The fixing portion includes a pair of fixing members extending from the yoke so as to be spaced apart from each other at a distance so as to protrude out of the motor portion.
It is preferable that an end of each of the pair of fixing members is provided with a latching end extending on both sides of the substrate.
It is preferable that the connector portion includes an auxiliary fixing portion having a groove into which the end portion of the pair of fixing members is fitted.
The motor cover preferably includes a lower cover on which the motor portion and the connector portion are seated, a seating portion for holding and fixing a part of the connector, and an upper cover coupled to the lower cover.
It is preferable that a protruding portion is formed at one edge of the connector portion, and a sliding groove is formed in the seating portion, in which the protruding portion is slidably inserted.
It is preferable that one or a plurality of mounting protrusions are formed on the periphery of the seating portion, and one or a plurality of mounting grooves for fitting the mounting protrusions are formed on the top cover.
Preferably, the connector portion and the substrate are electrically connected by a connection terminal, and the lead portion is protruded from the motor portion, and the lead terminal is electrically connected to the connector portion through the substrate.
The present invention has an effect that the assembly position of the substrate can be stably fixed by using the yoke included in the motor unit.
Further, the present invention has the effect of eliminating a separate guide part for guiding the fixing of the conventional substrate, thereby improving the assembling property and reducing the cost of airborne.
