Description

本発明は、複数のコンデンサを備えるコンデンサモジュールおよびその製造方法に関する。
The present invention relates to a capacitor module including a plurality of capacitors and a method for manufacturing the same.

電気エネルギを駆動や制動に用いる自動車などの機器では、電気エネルギの蓄積にコンデンサが用いられる。コンデンサは急速充放電特性に優れているので、始動や制動の迅速性が求められる自動車などの機器に適している。   In a device such as an automobile that uses electric energy for driving and braking, a capacitor is used to store electric energy. Since the capacitor has excellent rapid charge / discharge characteristics, it is suitable for devices such as automobiles that require quick start and braking.

搭載機器側の始動や制動に必要な電力に対応するため、コンデンサに大容量化が要請される場合、複数のコンデンサを用いることにより、必要な容量や高圧化が図られる。この場合、複数のコンデンサを集合させたコンデンサモジュールが用いられる。   In order to cope with the electric power required for starting and braking on the on-board equipment side, when a large capacity is required for the capacitor, the necessary capacity and high voltage can be increased by using a plurality of capacitors. In this case, a capacitor module in which a plurality of capacitors are assembled is used.

斯かるコンデンサモジュールではケース部材に複数のコンデンサを保持させることが知られている（たとえば、特許文献１）。また、コンデンサとケース部材の間に絶縁樹脂を充填し、コンデンサを絶縁するとともにケース部材の内部に強固に固定されたコンデンサモジュールを構成することが知られている（たとえば、特許文献２および特許文献３）。一方で、コンデンサモジュールについては、絶縁化とともに軽量化が要求されているが、絶縁樹脂を充填した場合、固定強度や絶縁性は高まるものの、軽量化を妨げることになる。そこで、絶縁樹脂を充填しないコンデンサモジュールも検討されている（たとえば、特許文献４）。このようなコンデンサモジュールでは軽量化を実現するため、樹脂製のケース部材に複数のコンデンサを装着している。各コンデンサを設置するケース部材はたとえば、端子側を覆う第１のケース部材、コンデンサの底部側を覆う第２のケース部材に分割され、これらケース部材を連結するセパレートタイプのケース部材が用いられている。
In such a capacitor module, it is known that a case member holds a plurality of capacitors (for example, Patent Document 1). In addition, it is known that an insulating resin is filled between a capacitor and a case member to form a capacitor module that insulates the capacitor and is firmly fixed inside the case member (for example, Patent Document 2 and Patent Document 2). 3). On the other hand, the capacitor module is required to be lightened as well as insulated. However, when the insulating resin is filled, although the fixing strength and the insulating property are increased, the weight reduction is hindered. Therefore, a capacitor module that is not filled with an insulating resin has been studied (for example, Patent Document 4). In such a capacitor module, a plurality of capacitors are mounted on a resin case member in order to reduce the weight. The case member for installing each capacitor is divided into, for example, a first case member that covers the terminal side and a second case member that covers the bottom side of the capacitor, and a separate type case member that connects these case members is used. Yes.

ところで、コンデンサモジュールでは、モジュール内のコンデンサの外部端子とバスバーの接続性を維持するため、外部端子間のバスバーによる接続と、この接続とは異なる部位でメインケースとコンデンサの固定を担うことが要求されている。つまり、コンデンサとコンデンサモジュールとの固定を外部端子で兼ねた場合、コンデンサモジュールを振動環境下で用いて、コンデンサモジュールに振動が加わると外部端子とバスバーの接続部に負荷が加わる。この場合、外部端子とバスバーの接続部にも負荷が掛かり、接続性が低下することがある。このため、バスバー接続用の外部端子とは別にコンデンサにはケース部材を固定する補助端子を設ける。   By the way, in the capacitor module, in order to maintain the connection between the external terminal of the capacitor and the bus bar in the module, it is required to connect the external case to the bus bar and to fix the main case and the capacitor at a part different from this connection. Has been. That is, when the capacitor and the capacitor module are also fixed by the external terminal, when the capacitor module is used in a vibration environment and vibration is applied to the capacitor module, a load is applied to the connection portion between the external terminal and the bus bar. In this case, a load is also applied to the connection portion between the external terminal and the bus bar, and the connectivity may be reduced. For this reason, an auxiliary terminal for fixing the case member is provided in the capacitor separately from the external terminal for connecting the bus bar.

コンデンサモジュールの搭載機器によっては、コンデンサモジュールが高温環境に設置される場合がある。コンデンサモジュールのケース部材が樹脂材料で形成されていると、補助端子のネジ受け部分が高温により緩むおそれがあるとの課題がある。   Depending on the equipment on which the capacitor module is mounted, the capacitor module may be installed in a high temperature environment. When the case member of the capacitor module is formed of a resin material, there is a problem that the screw receiving portion of the auxiliary terminal may be loosened due to high temperature.

補助端子の固定が緩んだ場合には、ケース部材とコンデンサとの固定がコンデンサの外部端子で担うことになり、コンデンサの外部端子に負荷が加わるという課題がある。コンデンサの外部端子に負荷が加わると、外部端子と外部回路との接続状態が劣化するなど、接続性に問題が生じるという課題がある。   When the auxiliary terminal is loosened, the case member and the capacitor are fixed by the external terminal of the capacitor, and there is a problem that a load is applied to the external terminal of the capacitor. When a load is applied to the external terminal of the capacitor, there is a problem that a problem arises in connectivity, for example, a connection state between the external terminal and an external circuit is deteriorated.

本発明は、複数のコンデンサが装着されるコンデンサモジュールにおいて、コンデンサの補助端子とケース部材との固定強度を高め、固定の安定性を向上させることを目的とする。

図１は、一実施の形態に係るコンデンサモジュールの一例を示している。このコンデンサモジュール２には、第１のケース部材としてメインケース４−１、第２のケース部材としてボトムケース４−２を備える。メインケース４−１およびボトムケース４−２はたとえば、熱可塑性合成樹脂で形成する。メインケース４−１およびボトムケース４−２は複数のコンデンサ６を収納する複数の収納部８を備える。   FIG. 1 shows an example of a capacitor module according to an embodiment. The capacitor module 2 includes a main case 4-1 as a first case member and a bottom case 4-2 as a second case member. The main case 4-1 and the bottom case 4-2 are made of, for example, a thermoplastic synthetic resin. The main case 4-1 and the bottom case 4-2 include a plurality of storage portions 8 that store a plurality of capacitors 6.

コンデンサ６には電解コンデンサ、電気二重層コンデンサなどが用いられる。コンデンサ６は、円筒状の外装ケースにコンデンサ素子が挿入され、外装ケースが封口板１０で封口される。この封口板１０は絶縁性合成樹脂などの絶縁板で形成され、この封口板１０には陽極端子１２、陰極端子１４および補助端子１６が形成されている。陽極端子１２、陰極端子１４および補助端子１６は封口板１０の成形の際、インサート成形により封口板１０に一体に取り付けられる。陽極端子１２にはコンデンサ素子の陽極が接続され、陰極端子１４にはコンデンサ素子の陰極が接続される。補助端子１６はコンデンサ６とメインケース４−１との固定などに用いられ、ネジ孔３８（図２のＢ）を備えている。   As the capacitor 6, an electrolytic capacitor, an electric double layer capacitor, or the like is used. In the capacitor 6, a capacitor element is inserted into a cylindrical outer case, and the outer case is sealed with a sealing plate 10. The sealing plate 10 is formed of an insulating plate such as an insulating synthetic resin. The sealing plate 10 is formed with an anode terminal 12, a cathode terminal 14, and an auxiliary terminal 16. The anode terminal 12, the cathode terminal 14, and the auxiliary terminal 16 are integrally attached to the sealing plate 10 by insert molding when the sealing plate 10 is formed. The anode terminal 12 is connected to the anode of the capacitor element, and the cathode terminal 14 is connected to the cathode of the capacitor element. The auxiliary terminal 16 is used for fixing the capacitor 6 and the main case 4-1, and includes a screw hole 38 (B in FIG. 2).

メインケース４−１にはコンデンサ６を収納する収納部８と端子取付け部１８が備えられる。端子取付け部１８は収納部８の天井部に形成され、平板状である。この端子取付け部１８には、コンデンサ６の陽極端子１２、陰極端子１４を貫通させる端子配置部２０、２２と、補助端子１６に対する端子受け部２４とを備えている。この実施の形態では、端子配置部２０、２２が端子取付け部１８の長手方向に配列されている。これに対し、端子受け部２４は端子配置部２０、２２の間隔中心位置でその間隔方向と直交方向に形成されている。このような配置関係から、各コンデンサ６の装着位置や装着方向が決定される。この端子受け部２４には固定ネジ２６が取り付けられ、コンデンサ６の補助端子１６を固定する。固定ネジ２６は頭部２８とネジ部３０とを備える。なお、端子受け部２４にはＵ字形の分離壁が形成されてもよい。この分離壁に連続して端子配置部２０、２２間を分離する分離壁が形成されてもよい。これら分離壁を形成すれば、陽極端子１２、陰極端子１４、補助端子１６のそれぞれに対して絶縁性を確保できる。   The main case 4-1 is provided with a storage portion 8 for storing the capacitor 6 and a terminal mounting portion 18. The terminal attaching part 18 is formed in the ceiling part of the accommodating part 8, and is flat form. The terminal mounting portion 18 includes terminal arrangement portions 20 and 22 that pass through the anode terminal 12 and the cathode terminal 14 of the capacitor 6, and a terminal receiving portion 24 for the auxiliary terminal 16. In this embodiment, the terminal arrangement portions 20 and 22 are arranged in the longitudinal direction of the terminal mounting portion 18. On the other hand, the terminal receiving portion 24 is formed in the direction perpendicular to the interval direction at the interval center position of the terminal arrangement portions 20 and 22. From such an arrangement relationship, the mounting position and mounting direction of each capacitor 6 are determined. A fixing screw 26 is attached to the terminal receiving portion 24 to fix the auxiliary terminal 16 of the capacitor 6. The fixing screw 26 includes a head portion 28 and a screw portion 30. The terminal receiving portion 24 may be formed with a U-shaped separation wall. A separation wall that separates the terminal arrangement portions 20 and 22 from the separation wall may be formed.

ボトムケース４−２には、筒状の収納部８が備えられている。ボトムケース４−２がコンデンサ６のボトム側に嵌合され、メインケース４−１に結合されると、各コンデンサ６がボトムケース４−２側に収納される。ボトムケース４−２の収納部８にはコンデンサ６が嵌入されており、コンデンサ６はボトムケース４−２に密着している。ボトムケース４−２とコンデンサ６が嵌合することで、コンデンサモジュール２に振動が加わった場合にも、コンデンサ６の振動による負荷を低減でき、コンデンサ４の陽極端子１２、陰極端子１４や補助端子１６への負荷を低減できる。さらに、コンデンサ６のボトム側を収納することで絶縁性を確保できる。   The bottom case 4-2 is provided with a cylindrical storage portion 8. When the bottom case 4-2 is fitted to the bottom side of the capacitor 6 and coupled to the main case 4-1, each capacitor 6 is accommodated on the bottom case 4-2 side. A capacitor 6 is fitted in the storage portion 8 of the bottom case 4-2, and the capacitor 6 is in close contact with the bottom case 4-2. By fitting the bottom case 4-2 and the capacitor 6, even when vibration is applied to the capacitor module 2, the load caused by the vibration of the capacitor 6 can be reduced, and the anode terminal 12, the cathode terminal 14 and the auxiliary terminal of the capacitor 4 can be reduced. The load on 16 can be reduced. Furthermore, the insulating property can be secured by storing the bottom side of the capacitor 6.

図２のＡは、端子取付け部１８の縦断面を示している。メインケース４−１の天井部には収納部８と一体に端子取付け部１８が形成されている。この端子取付け部１８には、既述の端子受け部２４が形成されている。この端子受け部２４は、貫通孔３２と、端子受け板３４とを備える。この端子受け板３４は端子取付け部１８と一体成形された金属板の一例である。この端子受け板３４には固定ネジ２６のネジ部３０を挿通させる挿通孔３６を備える。   FIG. 2A shows a longitudinal section of the terminal mounting portion 18. A terminal mounting portion 18 is formed integrally with the storage portion 8 on the ceiling portion of the main case 4-1. The terminal mounting portion 18 has the terminal receiving portion 24 described above. The terminal receiving portion 24 includes a through hole 32 and a terminal receiving plate 34. The terminal receiving plate 34 is an example of a metal plate formed integrally with the terminal mounting portion 18. The terminal receiving plate 34 is provided with an insertion hole 36 through which the screw portion 30 of the fixing screw 26 is inserted.

図２のＢは、補助端子１６の固定部の縦断面を示している。コンデンサ６の端子側にメインケース４−１が被せられる。メインケース４−１の端子取付け部１８の端子配置部２０、２２に、収納部８からコンデンサ６の陽極端子１２、陰極端子１４を貫通させる。同時に端子受け部２４に補助端子１６を配置させる。メインケース４−１の収納部８に装着されるコンデンサ６の補助端子１６は、メインケース４−１の内面側から端子受け部２４の端子受け板３４に位置決めされ、固定ネジ２６を端子受け板３４の上面側から補助端子１６のネジ孔３８にネジ部３０をねじ込む。これにより、この固定ネジ２６とコンデンサ６の補助端子１６との間にメインケース４−１の端子受け板３４が挟み込まれ、補助端子１６に固定ネジ２６が固定される。   FIG. 2B shows a longitudinal section of the fixing portion of the auxiliary terminal 16. The main case 4-1 is put on the terminal side of the capacitor 6. The anode terminal 12 and the cathode terminal 14 of the capacitor 6 are passed through the terminal placement portions 20 and 22 of the terminal mounting portion 18 of the main case 4-1 from the storage portion 8. At the same time, the auxiliary terminal 16 is disposed in the terminal receiving portion 24. The auxiliary terminal 16 of the capacitor 6 attached to the storage portion 8 of the main case 4-1 is positioned on the terminal receiving plate 34 of the terminal receiving portion 24 from the inner surface side of the main case 4-1, and the fixing screw 26 is connected to the terminal receiving plate. The screw portion 30 is screwed into the screw hole 38 of the auxiliary terminal 16 from the upper surface side of 34. As a result, the terminal receiving plate 34 of the main case 4-1 is sandwiched between the fixing screw 26 and the auxiliary terminal 16 of the capacitor 6, and the fixing screw 26 is fixed to the auxiliary terminal 16.

＜一実施の形態の効果＞ <Effect of one embodiment>

(1) コンデンサ６の補助端子１６を固定するメインケース４−１の端子受け部２４に金属板である端子受け板３４がインサート成形されているので、メインケース４−１の端子受け部２４を端子受け板３４により補強することができる。   (1) Since the terminal receiving plate 34 which is a metal plate is insert-molded in the terminal receiving portion 24 of the main case 4-1, which fixes the auxiliary terminal 16 of the capacitor 6, the terminal receiving portion 24 of the main case 4-1.

And a stable fixing structure can be obtained.

(3) コンデンサ６とメインケース４−１を固定する補助端子１６の固定が安定するため、コンデンサモジュール２を振動環境下で用いた場合でも、外部端子とバスバーの接続部に負荷が加わり難い構造となる。   (3) Since the fixing of the auxiliary terminal 16 for fixing the capacitor 6 and the main case 4-1 is stable, even when the capacitor module 2 is used in a vibration environment, a load is not easily applied to the connection portion between the external terminal and the bus bar. It becomes.

(4) メインケース４−１に金属板が一体成形された端子受け板３４を備えているので、補助端子１６と固定する際の位置合わせが可能となる。そのため、外部端子とバスバーとの接続部の高さ位置が一定となり、接続部に対する負荷を軽減できる。   (4) Since the main case 4-1 is provided with the terminal receiving plate 34 integrally formed with the metal plate, it is possible to align with the auxiliary terminal 16. Therefore, the height position of the connection part between the external terminal and the bus bar is constant, and the load on the connection part can be reduced.

(5) 金属板である端子受け部３４を補助端子１６との固定部に配置することで、コンデンサモジュール２を樹脂で成型することが可能となり、コンデンサモジュール２の軽量化とともに、コンデンサモジュール２の固定の安定化に寄与することができる。   (5) By arranging the terminal receiving portion 34, which is a metal plate, in the fixed portion to the auxiliary terminal 16, the capacitor module 2 can be molded with resin. This can contribute to stabilization of fixation.

〔他の実施の形態〕 [Other Embodiments]

上記実施の形態では、固定ネジ２６により固定したが、コンデンサ６の補助端子１６と端子受け板３４とをレーザ溶接などの溶接により固定してもよい。斯かる構成によれば、固定構造の簡略化とともに、部品点数を削減できる。また、溶接による固定のため、補助端子１６と端子受け部３４を一体化できるので、コンデンサ６とコンデンサモジュール２の補助端子１６による固定をより強固にできる。   In the above embodiment, the auxiliary screw 16 and the terminal receiving plate 34 of the capacitor 6 may be fixed by welding such as laser welding. According to such a configuration, the number of parts can be reduced while simplifying the fixing structure.
