Zusammenfassung: | PROBLEM TO BE SOLVED: To enhance reliability of a capacitor used for a hybrid automobile or the like.SOLUTION: A capacitor 1 includes a capacitor element, a frame body 5 which is configured in a frame-like shape to have a pair of opposed openings 5a and 5b and houses the capacitor element 2 in a hollow portion 7 between the pair of openings 5a and 5b, and resin 10 which is filled in the hollow portion 7 and solidified to integrate the capacitor element 2 and the frame body 5 into one body. A heat radiation mechanism is provided by this configuration, and thus even when a heat radiation plate is pressed against the capacitor 1 with relatively strong force, the stress received from the heat radiation plate is absorbed to some extent by the frame body 5, and the stress applied to the resin 10 and the capacitor element 2 is relaxed. As a result, the probability of breakage of the resin 10 and the capacitor element 2 can be reduced. Therefore, the capacitor 1 to which the present invention is applied has high reliability.SELECTED DRAWING: Figure 3
【課題】ハイブリッド自動車等に使用されるコンデンサの信頼性を向上させることを目的とする。【解決手段】本発明のコンデンサ1は、コンデンサ素子と、対向する一対の開口部5a、5bを有する枠型形状を成し、一対の開口部5a、5bの間の中空部7にコンデンサ素子2を収容した枠体5と、中空部7内に充填され、固化されることでコンデンサ素子2と枠体5とを一体化した樹脂10とを備えた構成となっている。この構成により、放熱機構を設けるため、コンデンサ1に放熱板を比較的強い力で押し当てたとしても、放熱板から受ける応力は枠体5によりある程度吸収され、樹脂10やコンデンサ素子2にかかる応力は緩和される。この結果、本発明は樹脂10やコンデンサ素子2の破損の可能性を低減することができる。したがって、本発明を適用したコンデンサ1は信頼性の高いものとなっている。【選択図】図3 |
