Abstract: A bus bar assembly is provided and includes a first linking bus bar, a second linking bus bar and plural power connectors. The first linking bus bar includes a first main bar, a first bending part and a first conducting part. The first bending part connects between the first main bar and the first conducting part. The second linking bus bar is disposed corresponding to and isolated from the first linking bus bar, and includes a second main bar, a second bending part and a third conducting part. The second bending part connects between the second main bar and the third conducting part. The power connectors are electrically coupled with the first main bar and the second main bar, respectively.

Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.

Abstract: A power supply is provided. The power supply includes a case, an electrical connector and a LED. The case includes a first side wall including an extension part. The extension part is extended from the first side wall toward a second side wall and has an aperture. Portion of the electrical connector is disposed in an accommodation space through an opening and includes a first base and a contacting ring. The first base is disposed in the accommodation space. The contacting ring is disposed on an exterior of the accommodation space. The LED is disposed in the aperture and includes a second base and a lens disposed on the second base. The second base and the contacting ring are located on different surfaces. The lens and portion of the second base are exposed from the opening. The other portion of the second base is covered by the contacting ring.

Abstract: A device having fool-proofing structure is configured to be inserted into a cabinet along a first direction and includes a case and an elastic sheet module. The elastic sheet module is disposed on a side of the case and includes a first end disposed on the case, a second end opposite to the first end, a first protrusion portion and a second protrusion portion. The first protrusion portion is adjacent to the second end, protrudes from the case and is configured to abut against the cabinet. The second protrusion portion is farther from the second end than the first protrusion portion, protrudes from the case, and is configured to make the second end and the first protrusion portion move toward the interior of the case as being pressed by a force.
