The electrical junction box is assembled in a state in which the main body is accommodated in the cover. The main body includes an opposing surface that opposes an inner surface of the cover. The opposing surface has a water capturing hole that is a recess that opens toward the inner surface of the cover. A first opposing distance between the inner surface of the cover and an upper opening edge of the water capturing hole is larger than a second opposing distance between the inner surface of the cover and a lower opening edge of the water capturing hole.

A housing arrangement of a power electronics device includes one power module or several identical power modules, each module with at least one part connected to a hazardous voltage, the arrangement further including a housing part having room for at least one power module. Each power module includes an enclosure part which essentially surrounds the power module and includes electrically insulating material. All the external connections of the power module are placed on one single wall of the enclosure part. The power modules and the enclosure part of the power modules are arranged such that when the power module is installed to the housing part the power module is electrically insulated from the housing part and external connections of the power module are directed to the front side of the housing part.

An object of the present invention is to ensure the reliability of a capacitor element by appropriately securing a heat path around the capacitor element. A power converter according to the present invention includes: a power semiconductor circuit unit that converts DC power into AC power; a capacitor element that smooths the DC power; a DC-side bus bar that transmits the DC power; a capacitor terminal that is connected to an electrode surface of the capacitor element and to the DC-side bus bar; and a case that forms a capacitor housing portion for housing the capacitor element, in which the DC-side bus bar has: a power supply-side terminal; a main body portion that is arranged at a position facing a bottom of the capacitor housing portion with the capacitor element interposed therebetween; and an extending member that is formed between the case and the capacitor element and formed from the main body portion toward the bottom of the capacitor housing portion, and that does not contact the electrode surface.

An electronic device may have a housing, electrical components, and other electronic device structures. A display may be mounted in the housing. The display may have a transparent display cover layer and a display layer such as an organic light-emitting diode display layer that is mounted to the underside of the transparent display cover layer. A flexible printed circuit with metal traces may be mounted under the organic light-emitting diode display layer.
