Abstract
A film capacitor includes: a capacitor element in which a metallikon electrode is formed at an end; a bus bar connected to the metallikon electrode; and a holding member having a slit into which the bus bar is inserted, the slit being formed with protrusions. The bus bar inserted into the slit is press-contacted with the protrusions, and as a result, the bus bar is held by the holding member. With this configuration, relative mounting accuracy (positioning accuracy) of positive and negative electrode bus bars is improved, and further, the bus bars can be easily connected to the capacitor elements.
Claims18
A film capacitor comprising:
- a capacitor element including a first metallikon electrode formed at one side end and a second metallikon electrode formed at another side end opposite to the one side end;
- a first bus bar connected to the first metallikon electrode and a second bus bar connected to the second metallikon electrode;
- and
- a holding member having slits into which the first bus bar and the second bus bar are inserted, respectively, wherein:
- the holding member is formed of an insulating material,
- the holding member is disposed over a top of the capacitor element,
- the first bus bar and the second bus bar face each other with the holding member interposed between the first bus bar and the second bus bar,
- the film capacitor further comprises an overlapping part formed of the first bus bar, the holding member and the second bus bar,
- the holding member has a flat plate, a first holding portion disposed at an end of the flat plate in a longitudinal direction and a second holding portion disposed at another end of the flat plate in the longitudinal direction,
- the first holding portion and the second holding portion include the slits, respectively, and
- a first face of the flat plate faces the first bus bar and a second face opposite to the first face of the flat plate faces the second bus bar.
A film capacitor comprising:
- a capacitor element in which a metallikon electrode is formed at an end;
- a bus bar connected to the metallikon electrode and having a locked part;
- and
- a holding member having slits into which the bus bar is inserted, an abutting part, and a locking protrusion,
- wherein when an extending direction of the slits is a first direction, a direction perpendicular to the first direction and parallel to a principal surface of the holding member is a second direction, and a direction perpendicular to each of the first direction and the second direction is a third direction,
- the bus bar is sandwiched between the slits in the second direction and is sandwiched between the slits in the third direction, and the bus bar is abutted by the abutting part from one side in the first direction and is locked by the locking protrusion from another side in the first direction.
A film capacitor comprising:
- a capacitor element including a first metallikon electrode formed at one side end and a second metallikon electrode formed at another side end opposite to the one side end;
- a first bus bar connected to the first metallikon electrode and a second bus bar connected to the second metallikon electrode;
- and
- a holding member having holding portions and a plate connecting the holding portions, wherein:
- the holding portions include slits into which the first bus bar and the second bus bar are inserted, respectively,
- the first bus bar and the second bus bar face each other with the holding member interposed between the first bus bar and the second bus bar,
- the holding member has a flat plate, a first holding portion disposed at an end of the flat plate in a longitudinal direction and a second holding portion disposed at another end of the flat plate in the longitudinal direction,
- the first holding portion and the second holding portion include the slits, respectively, and
- a first face of the flat plate faces the first bus bar and a second face opposite to the first face of the flat plate faces the second bus bar.
