[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric wiring structure of a motor actuator used for driving a door or the like of a vehicle air conditioner.

[0002]

[Prior Art]

 From the motor of the motor actuator, a terminal for connecting to the power supply is provided so that it is connected by two lead wires between the terminal and the terminal formed on the printed circuit board to connect to the terminal. It had been.

[0003]

[Problems to be solved by the device]

 However, since the lead wire is flexible, its shape and positions of both ends are not uniformly determined, and the lead wire is scattered at different times. Therefore, it is very difficult to automate the connection work, and there is a drawback that the assembly cost is high.

In addition, when the housing is closed, the lead wire may be damaged by being pinched, and in order to prevent such an accident and prevent the lead wire from interfering with a movable object, the lead wire may be damaged during assembly. There is a drawback in that it requires a great deal of nerve in the route, which causes assembly costs.

Therefore, an object of the present invention is to provide an electric wiring structure of a motor actuator that can easily connect a terminal of a motor and a terminal formed on a printed circuit board.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the electric wiring structure of the motor actuator of the present invention is basically such that the spring material bent in a U-shape is bent in the middle of the U-shape so that the spring material can be elastically deformed in the vertical direction. By forming a connection terminal by bending the mouth portion of the U-shaped portion to the side and pushing the connection terminal from the mouth side of the U-shaped portion with a housing, the tip portion of the U-shaped portion of the connection terminal is formed. And the part bent to the side are elastically pressed against the terminals of the motor and the terminals formed on the printed circuit board, which electrically connects the terminals of the motor and the terminals formed on the printed circuit board. The feature is that they are connected.

[0007]

[Action]

 By pressing the connection terminal from the mouth side of the U-shaped portion with the housing, the tip portion of the U-shaped portion of the connection terminal and the side portion bent to the motor terminal and the printed board were formed. The terminal of the motor is elastically pressed against the terminal, thereby electrically connecting the terminal of the motor and the terminal formed on the printed circuit board.

【Example】

 An embodiment will be described with reference to the drawings. Fig. 2 shows the outline of the overall configuration of the motor actuator. The motor 3 and the rotation of the motor 3 are decelerated and transmitted in the housings 1 and 2 made of plastic mold which are divided into upper and lower parts. The reduction gear group 4 and the like are accommodated.

The upper and lower housings 1 and 2 are fixed by screws 9 which are tightened from the upper surface side. Instead of the screws 9, hooks are integrally formed on the housings 1 and 2, and the hooks are fixed to each other. The upper and lower housings 1 and 2 may be fixed by the engagement.

The shaft 5 of the final gear 4a of the reduction gear group 4 serves as an output shaft and projects outside the housings 1 and 2. Further, a contact piece or the like for controlling the stop position of the output shaft 5 is provided on the rear surface of the final gear 4a and the surface of the printed circuit board facing the final gear 4a.

FIG. 3 is a view of the vicinity of a power supply connection terminal 11 provided on the rear surface of the motor 3 as seen from the rear of the motor 3, and FIG. 1 is an exploded perspective view of that portion. . A printed circuit board 13 is placed on a base 12 which is erected from the lower housing 2, and a recess (terminal receiving portion) 15 for receiving the terminal 11 of the motor 3 is formed on the base 12. There is.

A hole 16 is formed in the printed circuit board 13 at a position facing the terminal 11 of the motor 3. On the surface (upper surface) of the motor 3 opposite to the terminal 11 side, a motor power supply terminal 21 is printed and arranged adjacent to the hole 16.

Reference numeral 30 is a connection terminal for connecting the terminal 11 of the motor 3 and the terminal 21 of the printed board 13, and is formed of a conductive leaf spring material. The connection terminal 30 is basically bent in a U shape, and further, the U-shaped front half portion 31 is bent outward in a dogleg shape to form a connection terminal. 30 is formed so as to be elastically deformable in the vertical direction.

Further, the U-shaped mouth portion 32 of the connection terminal 30 is bent laterally at an acute angle on both sides. Reference numeral 33 is the bent portion. The lower surface of the upper housing 1 is formed with a pressing surface 35 that comes into contact with the connection terminal 30 and presses the connection terminal 30 from the mouth side thereof. Reference numeral 36 is a protrusion projecting from the upper housing 1 so as to be inserted between the U-shaped portions of the connection terminal 30 in order to prevent the connection terminal 30 from contracting inward.

When assembling the motor actuator thus formed, the terminals 11 of the motor 3 are first placed in the recesses 15 of the lower housing 2 according to the procedure shown from the bottom in FIG. Place on top of section 12.

Then, the U-shaped portion of the connection terminal 30 is inserted into the hole 16 of the printed board 13 from above, and the protrusion 36 of the upper housing 1 is inserted between the U-shaped portions of the connection terminals 30. The upper and lower housings 1 and 2 are fixed to each other with screws.

Then, the connection terminal 30 is pushed by the pressing surface 35 of the upper housing 1 from the mouth side (upper side) thereof, and as shown in FIG. 3, the tip portion of the connection terminal 30 is the terminal of the motor 3. It is pressed against 11 while elastically deforming, and the bent portion 33 at the mouth is pressed against the terminal 21 on the printed circuit board 13 while elastically deforming.

As a result, the terminal 11 of the motor 3 and the terminal 21 of the printed circuit board 13 are electrically connected to each other via the connection terminal 30, and in this state, the connection terminal 30 is driven by its own spring force. , 21 are elastically pressed.

[Effect of the device]

 According to the electric wiring structure of the motor actuator of the present invention, the terminal of the motor and the terminal of the printed circuit board are electrically connected via the connection terminal only by pushing the connection terminal made of the spring material with the housing. This part can be easily assembled at low cost by automatic assembly, and since soldering is unnecessary, there is an excellent effect that connection failure due to poor soldering can be eliminated.
