ものである。2. Description of the Related Art Some portable information devices such as a battery-operated device (hereinafter referred to as a device), especially a portable telephone and a PIM (personal information management) device, transmit information by bodily sensation vibration. The vibration generation method is often an electromagnetic drive method in terms of cost and energy efficiency. For example, a rotary vibration structure in which an eccentric weight is attached to a motor, a reciprocating vibration structure similar to a speaker, and the like. When attaching the electromagnetic vibrating body to a device, a method of firmly fixing the vibrating body with screws or the like or sandwiching the electromagnetic vibrating body through an elastic body is often adopted (however, the supporting rigidity is limited to the natural vibration. Make the number equal to or higher than the generated frequency). The latter method of mounting via an elastic body is frequently used because the electromagnetic vibrating body can be protected from an impact when the device is dropped by mistake, and the cushioning effect gives the device itself an impact reducing effect. There is a tendency. The present invention relates to an electrical connection method for a device having a structure in which an electromagnetic vibrating body is attached via an elastic body.

In order to facilitate attachment and detachment, a structure is employed in which a leaf spring protruding from the device elastically contacts the electrode of the battery. The second example is mounting of electronic components. FIG. 8 is a side view of a conventional motor mounting structure. Solder tightly because reliability is important. In an elastically supported electromagnetic vibrating body, there are many structures in which the lead wire 54 is extended and connected by soldering as shown in FIG. In the figure, a thin cylindrical motor 51 (electromagnetic vibrator) provided with an eccentric weight 2 has its case 53 covered with a synthetic rubber boot 55,

No. 08170. FIG. 9 is a perspective view of a conventional motor mounting structure.

It is fixed to the mounting plate 91 by 2. At one end of the case 83, there is an electrode (hidden and invisible in the figure) which communicates with the inside of the motor, and the power is supplied by contacting the elastic locking socket piece 93 projecting from the mounting plate 91.

According to this, the motor 81 can be easily attached to the device and can be reliably connected electrically.

た。However, this structure is not applicable when the electromagnetic vibrator is elastically held. This is because if the elastic connection is maintained, the electric connection portion slides due to the vibration and a contact failure occurs, as described in the publication. As described above, if the electromagnetic vibrator is held firmly, it is possible to make electrical connection by elastic contact and maintain the connection reliability, but if it is elastically held, the reliability of the elastic contact portion cannot be maintained. That is, they were in a trade-off relationship. Further, as will be described in detail in Examples, elastically supporting the electromagnetic vibrator requires the elastic contact portion to have a performance capable of coping with large displacement due to impact. However, there has been no technique that can meet this demand in the technical field of the present invention, which is composed of minute components.

As shown in the figure, a leaf spring-shaped power supply terminal 4 protrudes from one end of the case 3, and a substantially triangular elastic pressing body 6 is formed on a part of the boot 5 behind the power supply terminal 4. Then, when the motor 1 is incorporated in the device, the power supply terminal 4 elastically contacts the power supply land 13. Further, with the pressing of the case 3, the substantially triangular elastic pressing body 6 of the boot 5 presses from behind the power supply terminal 4.

FIG. 2 shows the pressing force of the motor having the structure shown in FIG. 1 when the power supply terminal 4 alone has no elastic pressing body 6 behind the power supply terminal 4, and FIG. . In each case, the horizontal axis represents the pressing force (unit: gf), and the vertical axis represents the terminal displacement (unit: mm). The terminal displacement refers to a displacement of the power supply terminal in a direction away from the motor, based on a state in which the device is incorporated. The terminal displacement at zero pressing force is the free height of the power supply terminal 4.

え塑性変形して押圧力が低下してしまう場合もあった。FIG. 2 is a diagram for explaining the relationship between the terminal displacement and the pressing force of the power supply terminal. As shown in FIG. 2, data was collected using samples having various free heights in consideration of manufacturing tolerances. As described above, in the case where the elastic pressing member 6 is not provided, the linear displacement has almost the same elastic coefficient. An average pressing force of about 45 gf is obtained, and if there is no vibration or impact, electrical connection can be made without any problem. However, it has been found that when the pressing force falls below 10 gf, relative motion occurs in the electrical contact portion between the power supply terminal 4 and the power supply land 13 due to vibration, and a high molecular weight polymer is generated, thereby impeding the electrical connection. Even when the pressing force was large, it was found that the leaf spring portion 4a still had a slight vibration, which also became a cause of generation of a high molecular polymer in a long term. Also, since the motor 1 is elastically supported,
When a drop impact force is applied to the device, the terminal is displaced on the negative side in the drawing, and the plate spring portion 4a of the power supply terminal 4 may exceed the elastic limit and may be plastically deformed to lower the pressing force.

いる。FIG. 3 is a diagram for explaining the relationship between terminal displacement and power supply terminal pressing force. FIG. 3 shows data when the elastic pressing member 6 made of synthetic rubber is arranged behind the power supply terminal 4. Again, data was collected using samples of various free heights. The elastic modulus is similar to that of FIG. 2 in the portion where the terminal displacement is large, but the elastic coefficient is large in the portion where the terminal displacement is small, that is, the portion close to the final mounting state, and a high pressing force of about 75 gf is obtained on average. . That is, the elastic pressing body 6 has a function of increasing the pressing force by about 30 gf. In addition, by increasing the elastic coefficient in a portion close to the final mounting state, an effect of preventing plastic deformation of the plate spring portion 4a of the power supply terminal when a drop impact force is applied to the device is exerted.

The horizontal axis represents the elapsed time, and the vertical axis represents the displacement amplitude of the leaf spring portion 4a of the power supply terminal in the mounting plate direction.
A small hole was drilled in the mounting plate 11 and measured using a laser displacement meter. In the figure, (a) the case where there is no elastic pressing body and (b) the case where there is an elastic pressing body behind the power supply terminal are recorded side by side.
Thus, the vibration amplitude of the power supply terminal could be reduced to about 1/5 by the elastic pressing member.

難となる。As described above, the present embodiment is configured such that the elastic pressing body 6 of the boot 5 presses the power supply terminal 4 against the power supply land 13 by pressing the case 3 when assembled into the device. Thereby, first, by setting the elastic coefficient of the elastic pressing member 6, the power supply terminal 4 and the power supply land 13 are set.
Contact pressure with a high degree of freedom. Therefore, an appropriate contact pressure can be obtained while responding to various conditions,
High connection reliability can be demonstrated in various applications. The main pressing force can be assigned to the elastic pressing body 6.
If it is attempted to increase the contact pressure only with the power supply terminal 4, the influence from the support structure of the power supply terminal 4 to the arrangement of the peripheral members is affected, and it is difficult to achieve both a large terminal displacement and a large pressing force.

を得ることができる。Secondly, when the elastic pressing member 6 is formed and the power supply terminal 4 is pressed, the double-supported beam vibration of the leaf spring portion 4a of the power supply terminal can be damped. As described above, this vibration also contributed to a decrease in reliability. Elastic pressing body 6
Is made of a material having good damping properties such as synthetic rubber, a specific example can be effectively reduced as described with reference to FIG. In this way, even if the electromagnetic vibrator vibrates, the sliding of the electrical connection portion can be reduced or prevented, and high contact reliability can be obtained in a vibration environment.

を得ることができる。In this embodiment, the elastic force of the power supply terminal 4 and the pressing force of the elastic pressing body 6 are combined. Thus, first, the contact pressure can be set with the combined characteristic of two different types of elastic force. If the elastic force of the metal leaf spring and the pressing force of the synthetic rubber are combined, it is possible to utilize the constant characteristics of the metal material that do not change over time and the vibration damping characteristics of the synthetic rubber. Therefore, high connection reliability can be obtained under various environmental conditions.

This characteristic has been described with reference to FIG. As shown in the figure, even if the motor 1 moves away from the mounting plate 11 due to external acceleration and the terminal displacement becomes large, the leaf spring portion 4a of the power supply terminal follows with sufficient margin, and moves in the opposite direction to reduce the terminal displacement. Alternatively, when the value becomes negative, the rigidity is increased to prevent plastic deformation. By such an operation, high connection reliability can be obtained in an impact environment.
