[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a contact terminal structure, and in particular, a contact having a pair of electrical contact portions spaced apart from each other in order to conduct to a pair of conducting surfaces of a predetermined device, and contact terminals provided with these electrical contact portions. It relates to the terminal structure.
[0002]
[Prior art]
FIG. 13 shows a manufacturing process of the sealed battery 80 as the predetermined device. First, as shown in FIG. 13 (A), a power generation element 81 is obtained by winding and flattening in a state where a positive electrode and a negative electrode are stacked with a separator interposed therebetween. The power generation element 81 includes a positive electrode terminal 85 as a conductive surface connected to the positive electrode and a negative electrode terminal 86 as a conductive surface connected to the negative electrode.
After the power generation element 81 is accommodated in the recess 83 of the metal resin composite film 82, the metal resin composite film 82 is bent from the center.
[0003]
As shown in FIG. 13B, the metal resin composite film 82 is folded from the center so that the metal resin composite films 82 are overlapped with each other, and the overlapped peripheral portions are heat-welded. Thus, a sealed battery package 83 is obtained.
Next, the left and right parts 83A and 83B in the peripheral portion of the sealed battery package 83 are bent in the direction of the arrow to obtain a sealed battery 80 shown in FIG.
[0004]
Next, a process of initially charging the sealed battery 80 before shipment will be described.
First, as shown in FIG. 14, the sealed battery 80 is set on the holding member 90 at a predetermined interval, and the holding member 90 is moved along the guide rail 91 to convey the sealed battery 80 in the direction of the arrow. To do.
[0005]
When the positive and negative terminals 85 and 86 of the sealed battery 80 reach the positive and negative terminals 93 and 94 for initial charging and the positive and negative terminals 95 and 96 for monitoring the charging status, the presser member 92 is moved in the direction of the arrow. Then, the positive and negative terminals 85 and 86 of the sealed battery 80 are pressed against the positive and negative terminals 93 and 94 for initial charging and the positive and negative terminals 95 and 96 for monitoring the charging state. As a result, the sealed battery 80 can be initially charged and the initial charging status can be monitored.
[0006]
[Problems to be solved by the invention]
Incidentally, in the conventional example described above, the relative position of each sealed battery 80 with respect to the holding member 90, or the relative position of each sealed battery 80 via the holding member 90, and further the relative position between the holding member 90 and the guide rail 91. Depending on the accuracy of the battery, it is difficult to press the positive and negative terminals 85 and 86 of all sealed batteries 80 against the positive and negative terminals 93 and 94 for initial charging and the positive and negative terminals 95 and 96 for monitoring the charging status. There's a problem.
There are various types of sealed batteries 80 with different sizes, and these batteries have different intervals between the positive and negative terminals 85 and 86 according to the size. Therefore, the terminals 93 and 94 for initial charging shown in FIG. 14 and FIG. 15 cannot be used for different types of sealed batteries 80.
[0007]
Further, as shown in FIG. 13, since the sealed battery 80 is obtained by winding and flattening in a state where the positive electrode and the negative electrode are stacked via the separator, the positive and negative electrodes of the sealed battery 80 are obtained. It is difficult to manufacture the gap between the terminals 85 and 86 with high accuracy.
Therefore, as shown in FIG. 14, the spacing S between the positive and negative terminals 85 and 86 of the sealed battery 80 varies.
[0008]
In addition, it is difficult to manufacture the parallelism of the positive and negative terminals 85 and 86 of the sealed battery 80 with high accuracy for the same reason. Therefore, as shown in FIG. 14, the negative electrode terminal 86 of the sealed battery 80 is inclined by a predetermined angle α with respect to the positive electrode terminal 85, and the interval between the positive and negative terminals 85 and 86 of the sealed battery 80 is a tolerance of a specified value. Even within, there is a risk of shaking.
[0009]
Further, as shown in FIG. 13B, by bending the left and right portions 83A and 83B of the sealed battery package 83 in the direction of the arrow, a distance S1 from the positive terminal 85 to the peripheral wall of the sealed battery 80, The distance S2 from the negative electrode terminal 86 to the peripheral wall of the sealed battery 80 may be different.
[0010]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a contact terminal structure that can cope with different types of sealed batteries and can cope with manufacturing errors of the sealed batteries. .
[0011]
[Means for Solving the Problems]
In order to achieve the above-described object, according to the present invention, a pair of electric devices spaced apart from each other are individually connected to a pair of conductive surfaces provided in a predetermined device. A contact terminal having a contact portion, and a contact terminal provided on each of the electrical contact portions is capable of contacting the conductive surface, and supports the contact piece and biasing toward the conductive surface And at least one of the electrical contact portions has a plurality of the contact pieces, and is arranged along a separation direction of the contact portions. .
[0012]
In the contact terminal structure configured as described above, a plurality of contact pieces are provided on at least one of the electrical contact portions, and these contact pieces are arranged along the separation direction of the contact portions. For this reason, even if the space | interval between the positive / negative electrode terminals of a sealed battery differs, the positive / negative electrode terminal can be reliably made to contact | abut to a contact piece.
Accordingly, it is possible to allow the accuracy of the container such as the distance between the terminals and the parallelism of the power generation element of the sealed battery or the relative position between the package for the sealed battery and the power generation element.
[0013]
In the present invention, as described in claim 2, at least one of the electrical contact portions has a plurality of the contact terminals.
By providing a plurality of contact terminals in at least one of the electrical contact portions, the number, shape, size, and interval of the contact terminals can be arbitrarily changed according to the size of the sealed battery. For this reason, it becomes possible to cope with various sealed batteries.
[0014]
In the present invention, as described in claim 3, as the support piece is pressed and deformed by the conductive surface through the contact piece, the contact piece becomes in the surface direction of the conductive surface. It is characterized in that it can be translated along.
[0015]
Here, when the positive / negative terminal is exposed to air, an oxide film is formed on the surface. Since this oxide film deteriorates conductivity, it is desirable to remove the oxide film. Therefore, in claim 3, the oxide film is removed by translating the contact piece along the surface direction of the conductive surface. For this reason, the positive and negative terminals of the sealed battery can be sufficiently brought into contact with the contact piece.
[0016]
Moreover, in this invention, as described in Claim 4, each said electric contact part has the said contact terminal in multiple numbers, It is characterized by the above-mentioned.
By providing a plurality of contact terminals on each of the electrical contact parts, the distance between the positive and negative terminals of the sealed battery is larger than when at least one of the electrical contact parts is provided with a plurality of contact terminals. Even if they are different, the positive and negative terminals can be reliably brought into contact with the contact piece.
[0017]

[0020]
The contact terminal structure 15 for initial charging is provided with six (a plurality) of positive and negative contact terminals 20 and 25 on the positive and negative electrical contact portions 17 and 18, respectively. , 25 are arranged along the direction in which the electrical contact portions 17, 18 are separated, and the front ends 22A, 27A of the positive / negative electrode support pieces 22, 26 are connected to the positive / negative electrode bus bars 30, 31, respectively. On the other hand, the contact terminal structure 16 for monitoring the charging state is provided above the contact terminal structure 15 for initial charging.
In this embodiment, the flat bus bars 30 and 31 are illustrated, but a bar bus bar may be used, and further, the bus bars 30 and 31 may be formed as long as they are electrically joined to the positive and negative support pieces 22 and 26. Etc. are optional.
[0021]
According to the first embodiment, the positive and negative electrical contact portions 17 and 18 are provided with a plurality of positive and negative contact pieces 21 and 26, and these contact pieces 21 and 26 are connected to the electrical contact portions 17 and 18. They were arranged along the separation direction. For this reason, even if the interval between the positive and negative terminals 12 and 13 of the sealed battery 11 is different, the positive and negative terminals 12 and 13 can be reliably brought into contact with the contact pieces 21 and 26.
Therefore, it is possible to deal with a sealed battery 11 of a different model, and to deal with manufacturing errors of the sealed battery 11.
[0022]
Here, the first embodiment is provided with a plurality of positive and negative contact terminals 20 and 25 in both the positive and negative electrical contact portions 17 and 18, respectively. The range can be further widened, and the allowable range for the manufacturing error of the sealed battery 11 can be further widened.
[0023]
The contact terminal structure 16 for monitoring the charging status has the same configuration as the contact terminal structure 15 for initial charging, and the negative electrode electrical contact portion 18 has the same configuration as the positive electrode electrical contact portion 17, and further has a negative electrode contact. The terminal 25 has the same configuration as the positive contact terminal 20. Therefore, in the following description, the description of the contact terminal structure 16 for monitoring the charging status, the negative electrical contact portion 18 and the negative contact terminal 25 is omitted, and the contact terminal structure 15 for initial charging, the positive electrical contact portion. 17 and the positive contact terminal 20 will be described in detail.
[0024]
As shown in FIGS. 2 and 3, the positive contact terminal 20 has a main portion 20A accommodated in the accommodating portion 17A of the positive electrical contact portion 17, and a contact piece 21 from the opening 17B of the electrical contact portion 17 to the positive terminal. 12, the contact piece 23 is provided on the ridge portion of the protrusion piece 21, the support piece 22 extending from the main portion 20 </ b> A protrudes outside the electric contact portion 17, and the tip 22 </ b> A of the support piece 22 is the positive electrode Connected to bus bar 30.
[0025]
Next, the effect | action of the contact terminal 20 of a positive electrode is demonstrated based on FIGS.
When the positive electrode terminal 12 of the sealed battery 11 reaches the contact terminal 20 of the positive electrode, the presser member 35 is moved in the direction of the arrow to bring the positive electrode terminal 12 into contact with the positive contact terminal 20, and from this state, the presser member 35 is moved to the arrow.

[0026]
Thus, the positive contact terminal 20 is elastically deformed with the bent portion 24 as a fulcrum, and the contact piece 21 is accommodated in the accommodating portion 17A of the electrical contact portion 17. At this time, in a state where the contact protrusion 23 is in contact with the positive electrode terminal 12, the contact protrusion 23 and the contact piece 21 are translated along the surface direction of the positive electrode terminal 12 to oxidize from the surface of the positive electrode terminal 12. The coating 12A can be removed.
[0027]
For this reason, the positive electrode terminal 12 of the sealed battery 11 can be sufficiently brought into contact with the contact protrusion 23 and the contact piece 21 to ensure conduction.

When the surface pressure of the contact piece 21 with respect to the positive electrode terminal 12 is large, the contact piece 21 in contact with the positive electrode terminal 12 is difficult to slip along the surface of the positive electrode terminal 12. For this reason, it is difficult to remove the oxide film 12A from the surface of the positive electrode terminal 12.
Further, if the surface pressure of the contact piece 21 with respect to the positive electrode terminal 12 is small, the contact protrusion 23 cannot sufficiently penetrate the oxide film 12A. For this reason, it is difficult to remove the oxide film 12A from the surface of the positive electrode terminal 12.
[0030]
