Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connection structure for connecting a plurality of thin batteries, and relates to a connection structure for a thin battery including a connection conductor that can rotate between the thin batteries .
[0002]
[Prior art]
For example prismatic lithium ion batteries for conventional cellular phone, because it does not have to Re cry stores battery thickness is about 6 mm, it was not able to reduce the thickness of the mobile phone body. On the other hand, when a thin battery is used to reduce the thickness of the mobile phone body, there is a problem that the battery capacity is insufficient to maintain the thin shape and store it in the space in the mobile phone. there were.
[0003]
[Problems to be solved by the invention]
That is, in the case where the microphone part of the mobile phone as shown in FIGS. 5 and 6 is opened and closed by the flipper, when the battery shown in FIG. 7 is simply halved, the battery capacity is also half that of the conventional lithium ion battery. As a result, there was a problem that the talk time was shortened.
[0004]
The present invention has been made in view of the above problems, and its object is to increase the capacity of a thin battery by making it possible to store a thin battery in the flipper. is there.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a battery capacity equivalent to that of a conventional rectangular lithium ion battery by arranging thin batteries connected by a rotatable connecting conductor in the main body and flipper portion of the mobile phone. Therefore, it is possible to provide a cellular phone that is about 5 to 7 mm thinner than before.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, a plurality of thin batteries are connected by a rotatable connecting conductor, whereby the thin batteries can be respectively disposed on the main body and the flipper portion of the mobile phone whose microphone portion is opened and closed by the flipper.
[0007]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the material and shape of this invention are not limited to the Example shown below.
[0008]
1 is a perspective view of a thin battery connected with the connection conductor of the present invention, FIG. 2 is a perspective view of the thin battery of FIG. 1 rotated through the connection conductor, and FIG. 3 is connected with the connection conductor of the present invention. 4 is an exploded view of the connection conductor of the present invention, and FIG. 5 is a cross-sectional view of the cellular phone in which the microphone part is opened and closed by the flipper. FIG. 6 is a perspective view of a state in which the flipper portion of FIG. 5 is opened, and FIG. 7 is a cross-sectional view of a conventional prismatic lithium ion battery disposed in the main body of a mobile phone whose microphone portion is opened and closed by the flipper.
[0009]
In the figure, 1 is a single cell, 2 is a rotatable connecting conductor, 3 is a positive terminal, 4 is a negative terminal, 5 is a rotating conductor for positive electrode, 6 is a rotating conductor for negative electrode, 7 is an insulating ring, 8 is conductive and A conductive ring 9 that assists in rotation, 9 is an insulating central shaft that supports each rotating body, and 10 is a nut made of Teflon that fixes the central shaft 9.
[0010]
The positive electrode rotating conductor 5 made of copper is sandwiched between a conductive ring 8 made of copper and a conductive ring 8 that assists rotation, and the conductive ring 8 is a positive electrode for connecting the main body of the positive electrode rotating conductor 5 and for connecting a flipper battery. It arrange | positions between the rotation conductors 5 for electricity, and assists electroconductivity and rotation. The negative electrode rotating conductor 6 is also arranged in the same manner as the positive electrode rotating conductor 5, and an insulating ring 7 made of Teflon for insulating the positive electrode and the negative electrode is disposed between the positive electrode rotating conductor 5 and the negative electrode rotating conductor 6. Further, these are arranged on a straight line by a central axis 9 made of Teflon so that they rotate smoothly, and are threaded at the previous portion so as not to be disengaged from the central axis 9, and are fixed by nuts 10 made of Teflon. .
[0011]
For the positive electrode of such a rotating conductor, the positive electrode terminal of the battery is welded, or when the slit is cut in advance in the rotating conductor, the terminal is inserted into the slit portion, and the negative electrode is also welded or inserted into the slit portion in the same manner. Thus, the thin battery connection structure including the rotatable thin battery connection conductor of the present invention is completed.
[0012]
【The invention's effect】
As described above in detail, according to the present invention, since the battery connection portion is connected by a rotatable conductive terminal, a thin battery can be arranged on both the main body portion and the flipper portion of a mobile phone having a microphone portion of a flipper type. Therefore, the mobile phone body can be made thinner.
