Abstract

<P>PROBLEM TO BE SOLVED: To provide a motor which accelerates the thinning of an apparatus being the object of mounting, while suppressing the mounting height. <P>SOLUTION: In this motor 1, the ground parts 14 of a pair of terminals 8 are juxtaposed across the center axis p of a motor case 2, and besides the interval L between the ground parts 14 and 14 is made larger than the diameter R of the motor case 2, so the seating stability of the motor at mounting is enhanced. Furthermore, the value of elastic deformation (amount of stroke) of the terminal 8 at mounting of the motor can be enlarged while avoiding the influence of the external form of the motor case 2 as far as possible. The terminal 8 can exhibit enough elastic power required to press it against the electric contact of an apparatus, and the electric connection becomes sure. Besides, at mounting of the motor, the height dimension of the motor 1 after elastic deformation of the terminal 8 can be brought close to the outside diameter dimension of the motor case 2 as far as possible. As a result, a motor small in mounting height dimensions materializes, and it contributes to the thinning of a portable telephone or the like. <P>COPYRIGHT: (C)2003,JPO

す。As a result of adopting a terminal having elasticity in this motor, it is possible to eliminate the need for soldering when mounting the motor on a device such as a mobile phone, and to improve the efficiency of the assembly work of the device. Also, the grounding portions of the pair of terminals are arranged in parallel with the center axis of the motor case,
Moreover, since the distance between the grounding portions is made larger than the diameter of the motor case, it is possible to improve the seating stability of the motor when mounting the motor. Furthermore, it is possible to increase the elastic deformation amount (stroke amount) of the terminal when mounting the motor while avoiding the influence of the outer shape of the motor case as much as possible. As a result, the terminal can sufficiently exert the elastic force required to press it against the electrical contact of the device, and ensure the electrical connection. Moreover, as described above, the space between the grounding portions is designed to allow the terminal to have a sufficient stroke while avoiding the influence of the motor case during elastic deformation as much as possible. The height dimension of the motor after elastic deformation can be made as close as possible to the outer diameter dimension of the motor case. As a result, a motor having a small mounting height dimension is realized, which helps to promote the thinning of the device side that constitutes the mounting target.

It is preferable to arrange it at. As described above, as a result of the elastic portion being located on the side of the motor case, the elastic portion can be sufficiently elastically deformed without contacting the motor case. Therefore, a motor having a small mounting height can be realized, and the device can be made thinner.

It is suitable to extend to. If the terminal has an elastic part that extends in a substantially U shape along the axis of the output shaft, the mounting height of the motor tends to increase, so the elastic part is placed on the side avoiding the motor case. It is effective if you do.

The distance L between the motor case 2 and the motor case 2 during elastic deformation gives a sufficient stroke to the elastic portion 30 of the terminal 8.
This is because the influence of is avoided as much as possible. Therefore, when the motor is mounted, the mounting height dimension H (see FIG. 1) of the motor 1 after the elastic deformation of the elastic portion 30 is:
The outer diameter R of the motor case 2 can be as close as possible. As a result, the motor 1 having a small mounting height dimension H is realized, which facilitates the thinning of the mobile phone as an example of the mounting target.

的である。Further, the elastic portion 30 is located on the side of the motor case 2, and the interval C between the elastic portions 30, 30 arranged in parallel.
As a result of making (see FIG. 3) larger than the diameter R of the motor case 2, the elastic portion 30 can be sufficiently elastically deformed without the elastic portion 30 hitting the motor case 2. In particular, in the motor 1 that employs the terminal 8 having the elastic portion 30 that extends in a substantially U shape along the axis of the output shaft 3, the mounting height dimension H tends to increase, which is effective.
