[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration type motor and a vibration type driving device, and more particularly to a connection device for electric parts and a vibration type motor and a vibration type driving device.

[0002]

2. Description of the Related Art Conventionally, in a vibration type motor, an elastic body in a vibrating body is excited by an electromechanical energy conversion element, for example, a piezoelectric element, and a circular or elliptical motion is formed on a driving surface of the elastic body. Japanese Patent Application Laid-Open No. 5-28 is a device that relatively frictionally drives a contact member that comes into pressure contact with the vibrator and the vibrator.
As disclosed in Japanese Patent No. 3837, the shape of a vibrating body is, for example, a bar-shaped one.

In this type of vibrating body, a plurality of piezoelectric element plates for exciting vibration are pressed and sandwiched in a state of being laminated, and an electrode plate is inserted between the piezoelectric element plates or an elastic body. Power is supplied to the piezoelectric element plate by applying a drive signal to these electrode plates. The terminal portions of these electrode plates extend in the radial direction of the piezoelectric element plate, and a flexible printed board is connected to the extended portions by soldering or the like.

On the other hand, as a configuration of a piezoelectric element in a rod-shaped vibration type motor, a type in which an electrode plate is eliminated, that is, a piezoelectric element is integrated in a laminated form, and a flexible printed circuit board is directly pressed and sandwiched between the piezoelectric elements. Electrical connection in the form,
There is also a type in which power is supplied by applying a drive signal to the laminated piezoelectric element via a flexible printed board in this state.

[0005]

However, in the case of the former type disclosed in Japanese Unexamined Patent Application Publication No. 5-283837 in the above-mentioned conventional example, a rod-shaped vibration type motor is used in order not to affect the vibration of the vibration type motor. Need to be made very thin. As a result, when the flexible printed circuit board is soldered to the electrode plate, the electrode plate may be erroneously bent, causing a problem such as disconnection of the electrode plate or short-circuit between terminal portions of adjacent electrode plates. Cheap. Further, when a vibration type motor is incorporated in a product, even if an external shock is applied to the product, a stress is applied to a terminal portion of the electrode plate, and the terminal portion may be easily disconnected.

On the other hand, in the case of the latter type in the above conventional example, the flexible printed circuit board and the laminated piezoelectric element are directly connected to each other without using the above-mentioned very thin electrode plate as an electric connection structure of the rod-shaped vibration type motor. Since the configuration is such that the connection is performed by pressing and holding, the disconnection of the terminal portion as described above does not occur.

If the flexible printed circuit board is accidentally pulled or an external shock is applied when a vibration type motor is incorporated in the product, stress concentrates on the weakly exposed wiring pattern and the pattern breaks. There was a case.

As a solution in this case, a method is considered in which only the electrical connection portion of the circuit pattern portion of the flexible printed circuit board is exposed to the laminated piezoelectric element to form a land portion, and the subsequent portion is surface-coated. According to this method, the weakly exposed wiring pattern portion does not slightly protrude from the laminated piezoelectric element in the radial direction, and the pattern disconnection problem is solved.

However, since it is necessary for the laminated piezoelectric element to reliably maintain a state in which the flexible printed circuit board is pressed and held, if there is a surface-covered portion in the pressed and held portion, there is a variation in dimensional accuracy and an appropriate load is applied. In some cases, it was not possible to obtain pressure holding, and the motor performance deteriorated.

When assembling the vibration type motor, the support member 11 is fitted to the shaft 2 and is abutted against the flange 2 b of the shaft 2, then tightened with the nut 14 and fixed to the shaft 2 with an adhesive. Thus, the assembly of the rod-shaped vibration type motor is completed in a state where the pressing state of the pressing spring 9 is maintained via the bearing 10 and the rotation output member 8. The above is the description of the structure of the motor.

Next, a configuration other than the rod-shaped vibration type motor will be described.

The circuit board 24 is attached to the fixed block 20 by a known method such as screwing. The above is the configuration of the motor driving device according to the present embodiment. As for the operation, first, an operation signal (AC voltage) is supplied from the circuit board 24 to the rod-shaped vibration type motor through the flexible printed circuit board 6. The piezoelectric element 5 vibrates due to the operation signal (AC voltage), and the vibration causes the elastic body 1 and the pressing body 4 to vibrate. Due to this vibration, the rotor 3 and the rotation output member 8 rotate together about the axis Z.

Only the piezoelectric element 5 is configured to face the piezoelectric element 5. The surface-covered circuit pattern portion 6b extends in a direction perpendicular to the axis Z of the rod-shaped vibration motor. When the flexible printed circuit board 6 is connected to the connector 25 of the circuit board 24 from this state, the flexible printed circuit board 6 is first bent in the direction of the axis Z of the motor (bent by approximately 90 °) to attach the interrupter 18 to the fixing member 19. Is attached by a well-known method, for example, adhesion, holding using elasticity, or the like.

This makes it possible to maintain the elastic force of the flexible printed circuit board 6 itself to extend in a direction perpendicular to the axis Z of the rod-shaped vibration type motor. Rise, sag, etc. are suppressed. After attaching the interrupter 18 to the fixing member 19, the electrical connection is completed by connecting the flexible printed circuit board 6 to the connector 25.

Next, the electrical connection between the flexible printed circuit board 6 and the piezoelectric element 5 will be described in detail with reference to FIG. FIG. 3 is a partially enlarged cross-sectional view showing a connection configuration between the flexible printed circuit board 6 and the piezoelectric element 5.

As shown in FIG. 3, in the flexible printed circuit board 6, the exposed circuit pattern portion 6a and the piezoelectric element 5 are in pressure contact with each other, and then the exposed circuit pattern portion 6a slightly protrudes from the piezoelectric element 5 in the radial direction. After that, the configuration of the flexible printed board is such that the surface-covered circuit pattern portion 6b is formed.

Since the exposed circuit pattern portion 6a has a thin shape, it is a weak portion. Therefore, at the time of assembly (when the flexible printed circuit board 6 is bent by approximately 90 ° in the direction of the axis Z of the motor and assembled), the operation of pulling the flexible printed circuit board 6 by mistake is performed, or the rod-shaped vibration type motor is incorporated into the product. When an external shock is applied to the product in this case, stress may concentrate on the exposed circuit pattern portion 6a, which is weak, and the pattern may be disconnected. Therefore, the exposed circuit pattern portion 6a and the piezoelectric element may be disconnected. 5 and the boundary between the exposed circuit pattern portion 6a and the surface-covered circuit pattern portion 6b. From the experimental results, it was found that a rubber-based adhesive was effective as a kind of the adhesive A for pattern disconnection.

(Second Embodiment) FIG. 4 is a partially enlarged sectional view showing a connection structure between a flexible printed circuit board and a piezoelectric element according to a second embodiment. Since the configuration other than the flexible printed circuit board is the same as that of the first embodiment, a detailed description thereof will be omitted.

In FIG. 4, reference numeral 101 denotes a flexible printed circuit board. The flexible printed circuit board 101 is pressed and held between the pressing body 4 and the piezoelectric element 5 similarly to the first embodiment. The flexible printed circuit board 101 includes an exposed circuit pattern portion 101a having a circuit pattern exposed and a surface-covered circuit pattern portion 101b having a surface covered with the circuit pattern, and the exposed circuit pattern portion 101a is configured to face the piezoelectric element 5. You. The surface-covered circuit pattern portion 101b extends in a direction orthogonal to the axis Z of the rod-shaped vibration motor.

When the flexible printed circuit board 101 is connected to the connector 25 of the circuit board 24 from this state, the flexible printed circuit board 101 is first bent in the direction of the axis Z of the rod-shaped vibrating motor (bent approximately 90 °). The interrupter 18 is attached to the fixing member 19 by a known method, for example, adhesion, holding using elasticity, or the like.

This makes it possible to maintain the elastic force of the flexible printed circuit board 101 itself to extend in a direction perpendicular to the axis Z of the rod-shaped vibration type motor. Sag and the like are suppressed. Then, the electrical connection is completed by connecting the flexible printed circuit board 101 to the connector 25 after attaching the interrupter 18 to the fixing member 19.

Next, the flexible printed circuit board 10
The electrical connection between the piezoelectric element 1 and the piezoelectric element 5 will be described in detail with reference to FIG.

In FIG. 4, the flexible printed circuit board 101 has an exposed circuit pattern portion 101a as described above.
And the piezoelectric element 5 are pressed and held in contact with each other, and when the thickness of the flexible printed circuit board 101 is t, the exposed circuit pattern portion 101a is formed to a position at least 10 t away from the boundary with the piezoelectric element 5 ( That is, since the thickness t of the flexible printed circuit board 101 is about 0.2 mm, 10 t is about 2 mm.
mm), and then the surface-covered circuit pattern portion 101
b is formed.

Since the exposed circuit pattern portion 101a has a thin shape, it is a weak portion as in the first embodiment. In other words, by setting the weakly exposed circuit pattern portion longer, stress concentration does not occur on the weakly exposed circuit pattern portion, and external shock is applied to the product when the rod-shaped vibration type motor is incorporated in the product. Even in this case, the configuration is such that pattern disconnection does not occur in the weakly exposed circuit pattern portion.

The distance between the exposed circuit pattern portion 101a and the boundary between the piezoelectric element 5 and the piezoelectric element 5 was determined by an external shock test as the minimum value at which pattern disconnection did not occur.
t or more (ie, the flexible printed circuit board 1
Since the plate thickness t of No. 01 is about 0.2 mm, 10 t is equivalent to about 2 mm).

(Third Embodiment) FIG. 5 is a partially enlarged sectional view showing a connection structure between a flexible printed circuit board and a piezoelectric element according to a third embodiment. Note that the configuration other than the flexible printed circuit board is the same as that of the second embodiment, and a detailed description thereof will be omitted.

The difference from the second embodiment is that, in addition to the configuration of the second embodiment, the flexible printed circuit board 101
The adhesive A is applied so as to cover the boundary between the exposed circuit pattern portion 101a and the piezoelectric element 5 which is an electromechanical energy conversion element. In other words, by setting the exposed circuit pattern portion 101a with a weak strain to a longer length so that stress concentration on the exposed circuit pattern portion 101a does not occur, there is no occurrence of pattern disconnection in the exposed circuit pattern portion 101a with a weak strain. At the same time as obtaining a highly reliable vibration type motor, the stress concentration on the boundary between the weakly stiff exposed circuit pattern portion 101a and the electric component can be reinforced by the adhesive A, so that the occurrence of pattern breakage is reliably reduced.
From the experimental results, it was found that a rubber-based adhesive was effective as a kind of the adhesive A for breaking the pattern.
