Abstract: A connector assembly includes a base, a wire unit, and a wire fixing unit. The base includes a body and two side wings. The two side wings are respectively rotatably connected to two opposite sides of the body, and each of the side wings includes a first fixing portion. The wire unit is located between the two side wings. The wire unit includes a connection seat disposed in the body, and various wires disposed in the connection seat and protruding from one side of the connection seat. The wire fixing unit includes two second fixing portions and various through holes, in which the through holes are located between the two second fixing portions, the two first fixing portions respectively clamp the two second fixing portions, and the wires correspondingly pass through the through holes.

Abstract: An isolated converter includes an input circuit, a transformer, a first switch, a second switch and a snubber circuit. The input circuit includes at least two input capacitors, and is configured to provide an input voltage. A divider node is arranged between the at least two input capacitors. The transformer includes a primary winding and a secondary winding to generate an output voltage on the secondary winding according to the input voltage. The primary winding of the transformer is electrically connected between the first switch and the second switch. The snubber circuit is electrically connected between the first switch and the second switch, and forms a discharge path with the primary winding. The snubber circuit is configured to receive a reflected voltage from the secondary winding back to the primary winding, and the divider node is connected to the discharge path.

Abstract: A locking device for connecting a first housing to a second housing is provided, wherein the first housing and the second housing are arranged along a first direction. The locking mechanism includes a first hook, a second hook, a movable member, and a driving member. The first hook and the second hook are affixed to the first housing, and respectively have a first engaging recess and a second engaging recess. The first engaging recess and the second engaging recess are arranged along the first direction. The movable portion has an engaging portion. The driving member is connected to the second housing and the movable member, and is configured to drive the movable member to move relative to the second housing. When the first housing is affixed to the second housing via the locking mechanism, the engaging portion is accommodated in the first engaging recess.
