[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to rotate a door mirror in a direction parallel to a traveling direction of a vehicle (storage position) when the door mirror is parked or after entering a garage, or to return to an original use state. In particular, the present invention relates to a connection structure between a board and a motor for supplying a drive current to the motor.

2. Description of the Related Art FIG. 8 is a perspective view showing an example of the prior art. That is, in this conventional example, a pair of terminals 42 and a lead wire 43 provided on the opposite side (rear end) of the output shaft 41 of the electric retractable door mirror motor 40 are connected to a receptacle 44 provided at the tip of the lead wire 43. The connection is made by coupling to the terminal 42. In addition, receptacles 44 are individually connected to the terminals 42.

However, in this conventional example, since the terminals 42 and the receptacles 44 are individually connected one by one, the work efficiency is poor, and wiring may be erroneously performed because the receptacles 44 have the same shape. Was. Further, the motor 40
Since the terminal 42 is protrudingly connected to the rear end of the battery, it is necessary to secure a space corresponding to the terminal 42, so that the space property is poor and the size of the electric storage unit is reduced.

Therefore, the present applicant has disclosed a connector 50 shown in FIGS. 6 and 7 (Japanese Utility Model Application No. 4-71064).
issue). That is, in this connector 50, a terminal 53 is provided on a case 52 of a motor 51, while a pair of upper and lower or separate housings 54 has a wire harness 56 taken out from a storage control board 55 having a contact for positioning. A pair of plug-shaped terminals 57 having one ends thereof are protruded, and these terminals 57 are inserted into terminals 53 of a fitting portion formed in the motor 51 to connect them.

[0005]

[Problems to be solved by the invention]
Although the wire harness and the motor can be connected by one operation, the holder 58 is connected to the frame 59.
In addition, when the wiring harness 56 is routed, care must be taken not to bite the wiring harness 56 and connect to the connector 50, so that the working efficiency is inferior. Further, the wire harness 56 is connected to the storage control board 5.
No. 5 needs to be soldered to the motor terminal, and there is a problem that the time required for assembly is long. Also, at this time, care must be taken so that the wire harness does not bite, so that the working efficiency is inferior and improvement is desired.

Accordingly, the present invention eliminates welding between a wire harness and a motor, which has been frequently used, so that the motor can be connected to the motor by one-touch operation, thereby improving work efficiency and durability during assembly. The purpose is to provide a device that fulfills the requirements.

[0007]

According to the invention of the present application, a motor of a driving source for rotating an electric retractable door mirror to a retracted or return position is fixed to a frame, and a fitting portion is recessed in this motor. An electric retractable door mirror characterized in that a board having connection terminals is disposed on a frame adjacent to a motor, and the connection terminals are fitted and fixed to the fitting portions.

The above-mentioned substrate includes a storage position control substrate, a part of which is extended to a fixed position of the motor, and a driving power supply pattern for the motor is set on the substrate and at one end of the pattern. Connection terminals are provided. Further, the substrate includes a storage / return position detection circuit, has a frame-shaped peripheral portion, and has a storage / return position detection circuit on one surface and a fitting portion recessed in the motor on the other surface. Are fixed to the elastic member protruding.

[0009]

According to the present invention, since work such as welding with a wire harness between the board and the motor is eliminated, the board to which the wire harness is connected is fixed to the frame, and the connection terminal is inserted into the fitting portion of the motor. The motor can be energized by itself.

In addition, the present invention eliminates the need to separately arrange corresponding connectors as in the above-described conventional example in the connection means between the board and the motor, thereby reducing the number of parts and improving the assembly efficiency. Was.

Further, a stable power supply is provided by connecting the substrate and the motor integrally, thereby avoiding the occurrence of operation failures such as connection failure due to cutting of the wire harness.

Further, a means for holding the substrate on the elastic material prevents a short circuit or the like caused by contact between the metals when the substrate is fixed to the frame, and provides a means for connecting the motor terminal with the wire harness. Eliminate,
And not only to make it compact as a component,
The motor can be connected either vertically or horizontally.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIGS. 2a and 2b are perspective views and sectional views showing a state in which a motor and a board are connected, and FIG. 3 is a plan view showing the back side of the board. FIG. The motor 1 includes, as an example, a fitting portion 4 that allows a terminal 3 to be described later to be inserted from above the case 2, and the fitting portion 4 includes an engagement groove 6 in which the terminal 5 is disposed inside the case 2.
(See FIG. 2b).

One example of the terminal 5 is that a leaf spring is bent in the engagement groove 6, and a wire from a power source (not shown) having one end fixed to a power source for driving the motor 1 is connected to one end thereof. A holder 8 is provided above a frame 7 which rotatably supports a mirror housing which is not used. The holder 8 has a positioning contact (not shown) therein, and the holder 8 is a storage position control board 9 that rotates on the contact.
Also has a function of arranging the wiring connecting the contacts 10.

The holder 8 has a through hole 8 at the center.
a, and the wire harness W is inserted into the through hole 8a.

Further, the storage position control board 9 has an elongated connecting plate 11 provided with a pattern P for connection to the motor 1 extending to the motor 1 side, and the terminal 3 connected to the power supply terminal thereof. Power is supplied by being inserted into and fixed to the fitting portion 4 and integrally connected to the terminal 5 of the motor 1.

FIG. 4 is a perspective view showing another embodiment, and FIG. 5 is a view taken in the direction of arrow A in FIG. That is,
The substrate 20 has its peripheral edge held by an elastic member 21 having an edge plate 21a raised in a frame shape along the outer shape of the motor 1, and detects a wire harness W for supplying power by detecting the storage / return position. It is connected to the circuit S in advance, and on the back surface of the substrate 20 of the detection circuit S, in the section of the edge plate 21a,
A fitting terminal 20b connected to the fitting portion 4 of the motor 1 is provided in a protruding manner.

The elastic member 21 is made of rubber, synthetic resin, or the like, has a deformed hexagonal shape as shown in the figure as an example, and has a screw hole 21b at the base where the reinforcing rib is formed. It is fixed with the frame 7 and the screw 22. That is, the elastic member 21 is disposed in the vertical position to hold the motor 1 in the vertical position, so that the space can be effectively used together with the embodiment in which the motor 1 is disposed in the horizontal position. Incidentally, the socket So shown in the figure is connected to a mirror angle adjusting actuator (not shown),
The wire harness W is inserted through one end of the wire harness W.

[0019]

With the above configuration, the present invention eliminates the connection between the wire harness and the motor as in the prior art, and connects the drive power of the motor simply by inserting the terminal protruding from the board into the fitting portion of the motor. As a result, the number of steps during assembly has been greatly reduced. Further, in the second embodiment, the number of parts can be reduced by eliminating the conventional connector by directly connecting the substrate held by the elastic member to the motor. Furthermore, by connecting the substrate to the motor, it is possible to prevent a failure due to a connection failure caused by cutting of a wire harness or the like, and to obtain high reliability and high durability. This is a useful idea.
