Abstract: A power conversion circuit energization unit includes a bus bar module and a conductive fixing bolt. The bus bar module includes conductive P and N bus bars connected to a switch element in a power conversion device and an insulative terminal block on which the bus bars are located. The fixing bolt fixes the terminal block to a housing in which the switch element is housed. A head of the fixing bolt and the P bus bar are separated from each other in an axial direction along which a shaft of the fixing bolt extends while facing each other.

Abstract: A sealing structure includes: a case that stores an in-vehicle electronic component and has an opening; and a first cover member that covers the opening of the case. The case includes: an protrusion member that has a sealing surface protruded to surround the opening; and a rib that is protruded on an opposite side of the opening with the protrusion member interposed therebetween. The rib has a discharge surface that is connected to the sealing surface of the protrusion member. The first cover member has an extension member that extends along the rib. The discharge surface of the rib is located to be lower than the sealing surface of the protrusion member while the case is arranged with the opening facing upward, and the extension member of the first cover member extends to be lower than the discharge surface of the rib.

Abstract: A capacitor unit includes a capacitor having a positive electrode and a negative electrode, a positive bus bar, a negative bus bar, a sealing resin, an insulator. The positive bus bar and the negative bus bar are respectively connected to the positive electrode and the negative electrode. The sealing resin seals the capacitor, a part of the positive bus bar, and a part of the negative bus bar. The insulator is located between the positive bus bar and the negative bus bar. The insulator includes a recess recessed from either surface of the insulator facing the positive bus bar or the negative bus bar. At least a part of the recess is exposed from the sealing resin.

Abstract: A power conversion device includes an electronic component, a cooler, a housing, protruding pipes, and annular seal members. Each of the seal members includes a seal body portion interposed between a corresponding one of the protruding pipes and the housing, and a flange portion extending outward from the seal body portion in a radial direction and contacting an outer surface of the housing from an axial direction. The housing includes a peripheral wall surface formed to surround the flange portion from an outer peripheral side, and an annular groove portion formed along an outer peripheral edge of the flange portion inside the peripheral wall surface. The peripheral wall surface is formed to extend outward, in the axial direction, from an axial contact surface of the housing contacted by the flange portion.

Abstract: A cover includes a cover body and an interlock connector. The cover body covers an opening provided in a case of a power conversion device and is electrically conductive. The interlock connector is electrically connectable to a receptacle connector provided inside the case. A noise shielding layer and a low conductivity layer are formed between the cover body and the interlock connector. The noise shielding layer is electrically conductive. The low conductivity layer is closer to the cover body than the noise shielding layer is, and is less electrically conductive than the cover body and the noise shielding layer.

Abstract: In a power converter, a semiconductor module incorporates therein a semiconductor element constituting a power converter circuit. A smoothing capacitor is configured to smooth a direct-current voltage applied to the semiconductor module. A pair of positive and negative busbars is configured to electrically connect the semiconductor module and the smoothing capacitor. The positive and negative busbars are arranged to face each other with a predetermined space therebetween. A discharge resistor is connected in parallel with the smoothing capacitor via the positive and negative busbars, and is configured such that an electrical charge stored in the smoothing capacitor flows through the discharge resistor as a discharge current. The positive and negative busbars are interposed between the discharge resistor and the smoothing capacitor.
