发明名称 High voltage capacitor
摘要 A high voltage capacitor comprises a columnar capacitor element body, made of a dielectric material, having a pair of principal surfaces opposing each other; a pair of electrodes arranged on the respective principal surfaces; a pair of terminal metal fittings connected to the respective electrodes; a case; and a resin part. The case contains a resin material and has a bottom part formed with an opening for exposing the terminal metal fitting and a trunk part extending from an edge of the bottom part in a direction intersecting the bottom part. The bottom part and trunk part define a space for containing the capacitor element body. The resin part is made of an insulating material and arranged within the case so as to seal the capacitor element body within the case. The case has a degree of hardness lower than that of the resin part.

主权项 1. A high voltage capacitor comprising: a columnar capacitor element body, made of a dielectric material, having a pair of principal surfaces opposing each other; a pair of electrodes arranged on the respective principal surfaces in the capacitor element body; a pair of terminal metal fittings connected to the respective electrodes; a case containing a resin material and having a bottom part formed with an opening for exposing one of the terminal metal fittings and a trunk part extending from an edge of the bottom part in a direction intersecting the bottom part, the bottom part and the trunk part defining a space for containing the capacitor element body; and a resin part made of an insulating material and arranged within the case so as to seal the capacitor element body contained in the space; wherein the case has a degree of hardness lower than that of the resin part, wherein the one terminal metal fitting is exposed by being inserted into the opening formed in the bottom part, wherein at least the one terminal metal fitting has an outer peripheral surface provided with a projection extending along a circumferential direction of the outer peripheral surface, wherein an edge portion defining the opening in the bottom part is in close contact with the outer peripheral surface of the one terminal metal fitting inserted in the opening, and wherein the edge portion is provided with a positioning part for abutting against the projection of the one terminal metal fitting and defining a position of the one terminal metal fitting.
