[Problems to be Solved by the Invention] FIG. 4 and FIG.
As will be understood with reference to FIG. 1, in the conventional example, one end of each of the harnesses 11a and 11b is connected to the motor terminal 4a.
In addition to soldering to 1 and 4a 2 , the harness was routed around to solder the other end to the board 10. For this reason, the soldering work in a narrow space requires a high degree of skill and a great deal of time and labor, and moreover, the harness is sandwiched between the casings of the matching lid type, or the harness is pulled to cause solder peeling. There was a risk of causing troubles such as. Further, as shown in FIG. 5, no special consideration is given to the positional relationship between the motor terminals 4a 1 and 4a 2, and the dashed route is rationalized and the overall shape is reduced (for example, in FIG. There is room for improvement in the indicated reduction of the dimension L).

In order to achieve the above object (improvement of workability and quality), a connecting structure of a motor and a board according to the present invention is configured to connect a motor for tilting a reflector and energization of the motor. The board on which the control circuit is formed is
In the optical axis adjusting device installed in a synthetic resin casing, both ends are provided with a conductive plate in the form of a leaf spring that elastically contacts the terminal of the substrate and the terminal of the motor, In addition, a part of the conductive plate is insert-molded in the casing. In the above-mentioned configuration, forming a leaf spring shape means that the shape is not only similar to a leaf spring but also has elasticity capable of functioning as a leaf spring. Further, a part being insert-molded does not necessarily have to be wrapped in the casing, and it is sufficient if it is fixed in contact with the casing.

According to the above structure, since a part of the conducting plate is insert-molded in the casing, there is no need to attach and fix the conducting plate to the casing. Moreover, both ends of the conducting plate are shaped like leaf springs,
Since the terminals of the motor and the terminals of the substrate are elastically contacted, contact conduction can be obtained without the need for soldering work. That is, conduction can be obtained simply by fitting the motor and the board to the leaf spring-like portion at the end of the conduction plate that is insert-fixed to the casing. Moreover, since the elastic contacts are maintained, the contacts are maintained even when subjected to vibrations, and there is no fear that conduction failure will occur. Furthermore, since there is no need for soldering as described above, a space for soldering work is not required and the entire optical axis adjusting device can be made compact.

Since the conductive plate is partly positioned with respect to the casing by insert molding, there is no risk of trouble such as being caught between the casing and the lid. Further, since no soldering work is required, there is no risk of thermal damage to the vicinity of the terminals, no special skill is required for assembly work, and so-called one-touch assembly is possible.

EXAMPLE Referring now to FIG. 1 and FIG. 2 together,
An embodiment of the present invention will be described. FIG. 1 is a schematic cross-sectional view of a drive unit portion of an optical axis adjusting device provided with an embodiment of a connection structure of a motor and a board according to the present invention, viewed in a direction parallel to a rotation axis of the motor. Since the drawings are schematically shown, they are not necessarily realistic projection views of the embodiment. FIG. 2 is a schematic cross-sectional view of the drive unit portion of the embodiment shown in FIG. 1 above viewed from a direction perpendicular to the rotation axis of the motor, and is not necessarily a realistic projection view. The portion of the casing where the conduction plate insert-molded with respect to the casing is covered and hidden is also drawn in the shape shown in the figure. (See FIG. 1) A motor 9b and a substrate 10 are housed in a casing 9a of an optical axis adjusting unit (also referred to as a drive unit) 9. The rotation output of the motor 9b is transmitted to the drive rod 9d via the reduction gear group 9c, and the drive rod 9d is moved forward and backward in the direction perpendicular to the plane of the drawing. A female screw is formed in the center hole of the drive rod 9d, and a male screw rod 9e is screwed therein. When the male screw rod 9e is turned, the drive rod 9d is rotated.
Relative to, the vehicle moves forward and backward in the direction perpendicular to the plane of the drawing. This function is used for aiming (initial value setting for optical axis adjustment). A stopper / guide piece 9f projects laterally from the drive rod 9d, and is guided by the guide surfaces 9a 1 and 9a 2 to prevent rotation around the axis and to translate in a direction perpendicular to the plane of the drawing. . (Mainly refer to FIG. 1 and also refer to FIG. 2) Terminals 9b 1 and 9b 2 of the motor 9b
Are electrically connected to the terminals of the substrate 10, a conduction plate / instep 12 and a conduction plate / B 13 are provided. The conductive plates 12 and 13 of this example are formed by punching out a phosphor bronze plate in an elongated shape and bending both end portions thereof at substantially right angles. The conduction plate / instep 12 and the central portions 12a and 13a of the second and second elbows 13 whose both ends are bent are embedded and fixed in the casing 9a by insert molding. As a result, the end portions of the conductive plate / instep 12 and the second side 13 facing the motor 9b are provided with motor spring pieces 12b, 13b in a shape rising from the bottom surface of the casing 9a by a height dimension H. It is formed and elastically contacts and conducts with the terminals 9b 1 and 9b 2 of the motor 9b.

With the above-mentioned structure, it is not necessary to attach the conducting plate / instep 12 and the instep / outer 13 to the casing 9a, and the central portion is positioned and fixed by insert molding. Only by fitting the board 10 into contact with the conductive plates 12 and 13, conduction is obtained, and no soldering work is required.

(See FIG. 1) The force for elastically pressing the motor spring piece 12b of the conductive plate / instep 12 against the motor terminal 9b 2 and the force of the conductive plate / external member 13 motor spring piece 13b for the motor terminal. It is desirable that the force elastically pressed against 9b 1 is equal. Therefore, the rising height dimension of the motor spring piece 12b and the rising height dimension of the motor spring piece 13b are aligned with H. Similarly, the rising dimension of the board spring piece 12c and the rising dimension of the board spring piece 13c are aligned with h. The inevitable consequence of the above construction is the two terminals 9b of the motor 9b.
1 and 9b 2 are positioned at the same height with respect to the bottom surface of the casing 9a and arranged in parallel with the plate surface of the substrate 10.
The cross-sectional shape of a motor is generally not necessarily circular,
Although it has a major axis direction and a minor axis direction, this embodiment is shown in FIG.
As shown in FIG. 7, the arrangement direction of the two terminals 9b 1 and 9b 2 is the minor axis direction of the motor 9b. As a result, the full width dimension W 1 including the motor 9b and the substrate 10 becomes shorter than the full width dimension W 2 in the conventional example shown in FIG. Further, since the conduction plate / instep 12 and the conduction / exhibit 13 are positioned and fixed by insert molding at their central portions with respect to the casing 9a, the conduction member (conduction plate or harness) is the casing 9a and the casing. There is no risk of being caught between the lid 9g. Further, two motor spring pieces 12b, 1
Since 3b are arranged at the same height (dimension H), it is easy to insert the motor 9b into the casing 9a and bring its terminals 9b 1 and 9b 2 into contact with the motor spring pieces 13b and 12b, respectively. For the same reason, the work of assembling the substrate 10 is easy. The motor 9b inserted into the casing 9a and covered with the casing lid 9g is sandwiched between the motor supporting rib 9g 1 provided on the casing 9a and the motor supporting rib 9g 1 provided on the casing lid 9g. Fixed. In this way, the motor 9
Mechanical support and electrical continuity of b are very easily and quickly achieved.

When the present invention is applied, since a part of the conducting plate is insert-molded in the casing, it is not necessary to attach and fix the conducting plate and the casing. Moreover, since both ends of the conducting plate are in the form of leaf springs and are elastically in contact with the terminals of the motor and the terminals of the substrate, contact conduction can be obtained without the need for soldering work. That is, conduction can be obtained simply by fitting the motor and the board to the leaf spring-like portion at the end of the conduction plate that is insert-fixed to the casing. Moreover, since the elastic contacts are maintained, the contacts are maintained even when subjected to vibrations, and there is no fear that conduction failure will occur. Furthermore, since there is no need for soldering as described above, a space for soldering work is not required and the entire optical axis adjusting device can be made compact.

Since the conductive plate is partly positioned with respect to the casing by insert molding, there is no risk of problems such as being caught between the casing and the lid. Also, since no soldering work is required, there is no risk of thermal damage near the terminals, no special skill is required for assembly work, and so-called one-touch assembly is possible. Play.
