A fuse circuit element (32) of a fuse module 22 for fail-safe is mounted on a fuse circuit board (31), and connected to wire terminal portions (36) made of respective wire one ends of stator coils. The fuse circuit board (31) has, as main terminals (33), through holes (33a) and land portions (33b), and the wire terminal portions (36) are soldered or welded with the wire terminal portions (36) inserted into the through holes (33a). The fuse circuit board (31) is supported in a cantilever manner by a pedestal portion (52) , and a space (53) is secured between the fuse circuit board (31) and a surface (51) of a housing (7) around the main terminals (33). With this, soldering or welding can be performed without heat escaping during soldering or welding by the space (53).

A display device includes a display panel; a back cover supporting the display panel on a rear surface of the display panel; one or more flexible films electrically connected to one end of the display panel and on a surface of the back cover; a film cover covering the flexible films and the end of the display panel; a printed circuit board electrically connected to the flexible films and on the surface of the back cover; and a roller having a first flat portion, a second flat portion, and a curved portion. The display panel and the back cover are wound around or unwound from the roller. The end of the display panel is in line with the first flat portion while the printed circuit board is in line with the second flat portion when the display panel and the back cover are fully wound around the roller.

The present disclosure relates to an electric circuit system. The system includes a housing, a printed circuit board mounted within the housing, an electric component conductively mounted to the printed circuit board, and a cooling system for transferring heat away from of the electric component. The printed circuit board is compartmentalizing the inside of the housing into a first compartment and a second compartment, and the electric component is situated in the first compartment. The cooling system includes at least one first heat transferring element located adjacent to the electric component. The at least one first heat transferring element is secured to the housing surrounding the second compartment capable of forming a heat flowing path defined to transfer heat from the electric component to the housing via the at least one first heat transferring element.

An electronic component includes a circuit carrier unit and a housing at least partly encompassing the circuit carrier unit. The circuit carrier unit has an electronic element assembled on the circuit carrier unit. The circuit carrier unit has a first section and a second section arranged at a distance from the first section and opposing the first section. The housing has a first receiving portion receiving the first section and a second receiving portion receiving the second section. The first receiving portion and the second receiving portion are separated from each other by a cooling clearance.

Disclosed herein is a sensor module that includes a substrate having a top surface and a back surface, a sensor element mounted on the top surface of the substrate, an external terminal formed on the back surface of the substrate, and a case fixed to the substrate so as to cover the sensor element. The case has a top plate part having a plurality of through holes. The top plate part has a center area having no through holes and a through hole formation area having the plurality of through holes, the through hole formation area being positioned so as to surround the center area.

A hybrid edge connector includes an insulative housing with a slot lined with signal terminals, in a signal portion, and power terminals in a power portion. The power terminals may be made with multiple layers, with each layer formed into one or more fingers. Each finger may be configured to make contact with an edge of a card inserted in the slot such that each terminal has multiple contact points to the card and can carry a large current. To support a large current, the card may be a hybrid card, with a signal portion formed using a conventional PCB manufacturing techniques and a power portion formed with one or more blades mechanically coupled to the signal portion. The slot in the connector housing may have different widths in the signal and power portions and the center lines of those portions may be offset with respect to each other.
