Power converter and illumination device using the power converter

摘要

A power converter includes a mounting substrate, a one-piece-type connector including an input connector and an output connector, the input connector and the output connector being formed in one-piece and arranged side by side; and a case made of an electrically conductive material. The one-piece-type connector includes lead terminals configured to connect the input cable and the output cable to a power converting circuit and an electrically conductive ground connection portion electrically connected to the case through an electrically conductive member. The ground connection portion includes a shield surface arranged to extend along at least a portion of a side surface of the output connector.

主权项

1. A power converter, comprising:
a mounting substrate mounted with a power converting circuit for converting electric power supplied from a power supply and supplying the converted electric power to a load; a one-piece-type connector including an input connector by which an input cable for inputting the electric power supplied from the power supply to the power converting circuit is connected to the mounting substrate and an output connector by which an output cable for outputting the converted electric power to the load is connected to the mounting substrate, the input connector and the output connector being formed in one-piece and arranged side by side; and a case made of an electrically conductive material and configured to accommodate the mounting substrate and the one-piece-type connector, wherein the one-piece-type connector includes lead terminals configured to connect the input cable and the output cable to the power converting circuit and an electrically conductive ground connection portion electrically connected to the case through an electrically conductive member, the ground connection portion including a shield surface arranged to extend along at least a portion of a side surface of the output connector, wherein the one-piece-type connector further includes a connecting portion to interconnect the input connector and the output connector, the ground connection portion including a base portion installed on the connecting portion and an upstanding portion standing up from the base portion to extend along a side surface of the output connector, the upstanding portion serving as the shield surface, wherein the ground connection portion further includes leg portions extending from the base portion so as to make contact with the mounting substrate, each of the leg portions including a bent portion flexed depending on a difference in an attachment height of the lead terminals with respect to the mounting substrate, and wherein the electrically conductive member includes a grounding circuit formed on the mounting substrate, the leg portions making contact with the grounding circuit.
