Abstract: Provided is a noise reduction device including: a conductive bar of conductive material extending through a through hole in a metal housing to the outside; a magnetic material core of magnetic material disposed at a peripheral edge of the conductive bar; a substrate attached to the conductive bar so as to be adjacent to the magnetic material core; a capacitor mounted on the substrate and having a first terminal connected to the conductive bar and a second terminal connected to an inner wall of the through hole; and a blocking unit blocking an opening of the through hole so as to affix the conductive bar to the metal housing. The magnetic material core, the substrate, and the capacitor are disposed in the through hole blocked by the blocking unit; and the conductive bar has an outer end that functions as an output terminal.

Abstract: A connector including: a conductive portion that is brought into pressure contact with a bus bar and is electrically connected to the bus bar when the bus bar is inserted into an inserted portion; and a pressing portion configured to be displaceable to a first position and a second position, and receives a force acting from the bus bar when the bus bar is inserted into the inserted portion, is displaced from the first position to the second position, and presses the conductive portion at the time of the displacement to elastically deform at least a part of the conductive portion, in which the conductive portion is configured to cause, when pressed by the pressing portion and elastically deformed, an elastic force generated with the elastic deformation to act on the bus bar to increase a contact pressure with respect to the bus bar.

CPC classification number: H03H7/09 , H01F17/06 , H01F2017/065
Abstract: There is provided a noise filter. A noise filter according to the present disclosure includes: a non-divided type magnetic core in which a through-hole having a first opening and a second opening at respective ends of the through-hole is formed; a conductive coupling terminal including a first connection portion and a second connection portion at respective ends of the conductive coupling terminal, the first connection portion and the second connection portion being connectable to busbars, the conductive coupling terminal being disposed inside the through-hole; and a holding portion that holds the coupling terminal disposed inside the through-hole. The coupling terminal is held to the magnetic core by the holding portion in a state where the first connection portion faces the first opening from inside of the through-hole and the second connection portion faces the second opening from inside of the through-hole.

Abstract: Provided is a noise reduction device including: a conductive bar of conductive material; a metal tubular portion with a through hole having the conductive bar penetrating therethrough and accommodating a magnetic material core and a substrate therein; a capacitor mounted on the substrate and having a first terminal connected to the conductive bar and a second terminal connected to an inner wall of the through hole; and a blocking unit blocking an opening of the through hole so as to affix the conductive bar with respect to the metal housing and the tubular portion. The tubular portion includes an outer peripheral surface having a threaded engagement part threadedly engaged with the metal housing; and the conductive bar has an outer end that functions as an output terminal.
