[Industrial applications]

 The invention of the present application is an electric storage that uses a motor drive to rotate the door mirror in a direction (storage position) parallel to the traveling direction of the vehicle when the door mirror is parked or after entering a garage, or to return to the original use state. The present invention relates to a connection structure between a substrate and a motor, which is used in a door mirror and particularly supplies a driving current to the motor.

[Prior art]

 FIG. 8 is a perspective view showing a conventional example. That is, in this conventional example, the pair of terminals 42 and the lead wire 43 provided on the opposite side (rear end) of the output shaft 41 of the electric retractable door mirror motor 40 and the lead wire 43 are provided at the tip end of the lead wire 43. Are connected by coupling to the terminal 42. Receptacles 44 are individually connected to the terminals 42.

However, in this conventional example, since the terminals 42 and the receptacles 44 are individually coupled one by one, work efficiency is poor, and because the receptacles 44 have the same shape, wiring may be erroneously performed. It was Further, since the terminal 42 is connected to the rear end of the motor 40 by projecting it, it is necessary to secure a space for the terminal 42, so that the space property is poor and it is an adverse effect to realize the miniaturization of the electric storage unit.

Therefore, the present applicant has previously disclosed the connector 50 shown in FIGS. 6 to 7 (Japanese Patent Application No. 4-71064). That is, in this connector 50, terminals 53 are arranged in a case 52 of a motor 51, while a wire harness 56 taken out from a storage control board 55 having contacts for positioning in a pair of upper and lower or separate housings 54. A pair of plug-shaped terminals 57, to which one end of the motor is connected, are provided in a projecting manner, and the terminals 57 are inserted into the terminals 53 of the fitting portion formed in the motor 51 to connect them.

[0005]

In the second conventional example described above, the wire harness and the motor can be connected by one operation, but the holder 58 is attached to the frame 59, and the wire harness 56 is routed. Occasionally, it is necessary to take care that the wire harness 56 is connected to the connector 50 without being caught in the wire harness 56, resulting in poor work efficiency. In addition, it is necessary to solder the wire harness 56 to the motor terminals of the storage control board 55, which causes a problem that it takes a lot of time to assemble. Also, in that case, care must be taken so that the wire harness is not caught in it, so work efficiency is inferior and improvement is desired.

In view of this, the present invention eliminates welding between a wire harness and a motor, which are conventionally used so that the motor can be connected to the motor by one-touch operation, thereby improving work efficiency during assembly and improving durability. The purpose is to provide improved ideas.

[0007]

[Means for Solving the Problems]

 According to the present invention, the motor of the drive source for rotating the electric retractable door mirror to the retracted or retracted position is fixed to the frame, and the fitting portion is recessed in the motor, while the motor is connected to the frame at the position adjacent to the motor. The electric retractable door mirror is characterized in that a board provided with terminals is disposed and connection terminals are fitted and fixed to the fitting portion.

Further, the board includes a storage position control board, a part of which extends to a fixed position of the motor, and a drive power source pattern for the motor is set on the board, and one end of the pattern is set. A connection terminal is provided on the. Further, the board is provided with a storage / return position detection circuit, has a frame-shaped peripheral portion, and is fitted with the storage / return position detection circuit on one surface and a recess on the motor on the other surface. It is characterized in that the connection terminal to the section is fixed to the protruding elastic member.

[Function of the device]

 Since the present invention eliminates the work such as welding by the wire harness between the board and the motor, the board to which the wire harness is connected is fixed to the frame, and the connecting terminal is inserted into the fitting part of the motor to make the motor. Can be energized.

Further, according to the invention of the present application, in the connecting means for connecting the substrate and the motor, it is not necessary to individually arrange the corresponding connectors as in the conventional example, and the number of parts can be reduced and the assembling efficiency can be improved. Played

Further, the board and the motor are integrally connected to avoid a malfunction such as a connection failure due to the disconnection of the wire harness, and a stable power is supplied.

[0012] Furthermore, it is possible to prevent a short-circuit accident due to contact between metals when fixing the substrate to the frame by means of holding the substrate on the elastic material, and to connect the motor harness to the motor terminal by a wire harness. Not only can it be eliminated and made into components to make it smaller, but it can also be connected vertically or horizontally.
