Abstract
Official abstract text for this publication.
A film capacitor includes: a capacitor element in which a metallikon electrode is formed at an end; a bus bar connected with the metallikon electrode; a case having a container for housing the capacitor element and the bus bar; a lid member which covers an opening of the container; and a heat conducting member disposed between the bus bar and the lid member. The lid member has a protrusion on a side facing the heat conducting member, the protrusion is in contact with the heat conducting member, and the heat conducting member is in contact with the bus bar.
First claim
Opening claim text (preview).
What is claimed is: 1. A film capacitor comprising: a capacitor element in which a metallikon electrode is formed at an end; a bus bar connected with the metallikon electrode; a case having a container for housing the capacitor element and the bus bar; a lid member which covers an opening of the container; and a heat conducting member disposed between the bus bar and the lid member, wherein the lid member has a protrusion on a side facing the heat conducting member, the protrusion is in contact with the heat conducting member, and the heat conducting member is in contact with the bus bar. 2. The film capacitor according to claim 1 , wherein a resin layer for sealing the capacitor element that the bus bar is connected to is formed inside the container, and the lid member is configured with a first lid member including the protrusion and a second lid member, and the first lid member and the second lid member cover the opening of the container. 3. The film capacitor according to claim 2 , wherein the protrusion has a portion embedded in the resin layer. 4. The film capacitor according to claim 2 , wherein the second lid member is provided at a center portion in a longitudinal direction of the opening. 5. The film capacitor according to claim 1 , wherein the lid member and the protrusion are integrated. 6. The film capacitor according to claim 1 , wherein the heat conducting member is sandwiched between the protrusion and the bus bar.
