おける接触不良が略同時期に生じていた。The conventional battery mounting structure described above has the following problems. (A) The negative electrode surface 33 of the coin-shaped battery 30 when the coin-shaped battery 30 is attached to or detached from the battery mounting portion 40, or when the battery 30 is rotated by a shock received while carrying a small electronic device. And two contacts 62 of the negative terminal 60
Due to the friction generated between the nickel and nickel, the nickel applied to the electrode surface of the coin-shaped battery 30 is scraped off, and it becomes an oxide to cause poor contact. In particular, the contacts 62, 62 of the negative terminal 60 have the same shape, that is, the contact with the negative electrode surface 33 of the coin-shaped battery 30 is substantially a point contact. Poor contact occurred at about the same time.

The same happens with the friction that occurs between the two. Also in this case, the contacts 72, 72 of the plus terminal 70 have the same shape in both sheets, that is, both of them have a shape in which the contact with the peripheral side surface 31 of the plus electrode 32 of the coin-shaped battery 30 is a substantially linear contact. Therefore, the contact failure in each contact 62 occurred at about the same time. However, since the point contact and the line contact have different shapes, the contact failure time was different.

Therefore, due to the difference in physical shape between the point contact and the line contact, the contact of the negative terminal and the positive terminal and the coin may change due to the attachment / detachment of the coin battery or the rotation of the coin battery. Even if friction occurs between both electrode surfaces of the battery, the first contact and the second contact
Since the contact resistance of the contact of No. 1 to the battery is different from each other at different times, contact failure with the battery is unlikely to occur,
It is possible to stabilize the contact over time.

必ずしも１対４の関係になるとは限らない。FIG. 6 (a) shows an example of the change in contact resistance over time when the electrode surface of the coin battery 30 is brought into point contact, and FIG. 6 (b) shows the electrode of the coin battery 30. It is an example of a change over time in the contact resistance when the surface is in line contact. In the case of point contact, the area of contact with the electrode surface of the coin-shaped battery 30 is smaller than that in the case of line contact, so the pressure between the electrode surface of the coin-shaped battery 30 increases. Therefore, the time when the nickel or the like applied to the electrode surface of the coin-shaped battery 30 is scraped off and the contact resistance increases becomes earlier than in the case of line contact, and as shown in FIGS. 6A and 6B, the contact resistance becomes constant. In the period T, the number of times the point contact exceeds the borderline which is the upper limit that can be used is greater in the point contact. In this figure, the point contact is "4" while the line contact is "1". In addition, it is clear from the difference in physical shape that the number of times of crossing the border line in the point contact becomes larger than that in the line contact.
The relationship is not necessarily one to four.

ことが分かる。By using point contact and line contact in combination, the line resistance is below the border line even in the period in which the point contact exceeds the border line. Therefore, in this period, the contact resistance is higher than in the case of only point contact. It is possible to avoid a high state. Further, although there is a partial overlapping period T1 even when the line contact exceeds the border line, it can be used in a period other than the overlapping period T1. Therefore, it can be seen that the period in which the contact resistance is high becomes shorter than in the case where the contacts having the same shape are used.

Of the No. 03, the first contact 102 has a point-like projection 102a formed at the tip thereof, and the second contact 103 has a line-like projection 103a formed at the tip thereof, so that The contact with the electrode surface 33 is made at the same time by the point and the line, and the tip of the first contact 122 of the two first and second contacts 122, 123 of the positive terminal 120 is contacted by the point. Forming the protrusions 122a, the second contact 12
The peripheral side surface 31 of the positive electrode surface 32 of the coin-shaped battery 30 is formed by forming the linear protrusion 123a at the tip portion of 3.
It was designed to make contact with the point and line at the same time.

Even if friction occurs between both electrode surfaces of the first contactor 102 and the second contactor 102,
Contactor 103 (first contactor 122 and second contactor 1
23) Since the contact resistance increases at different timings due to the difference in the physical shape of the protrusions with respect to the coin-shaped battery 30, the contact failure with the coin-shaped battery 30 is unlikely to occur and the contact is stabilized over time. Can be achieved.
