Patent number: 10297935Abstract: The invention discloses a circuit board output structure, which includes a power output section disposed on a circuit board and at least one metal connection stand electrically connected to the power output section. Each metal connection stand includes a first connection piece showing an included angle with respect to the circuit board. A plurality of connection holes for electrically connecting output wires are formed on the first connection piece. When it is required to change an output specification, the replacement can be more simple and convenient since the metal connection stand may be directly replaced without replacing the whole circuit board. Because the first connection piece has the included angle specified with respect to the circuit board, R angle and stress of the inserted output wires may be reduced to prevent the output wires from damage, detaching from the circuit board or having poor electrical contact after the assembly.Type: GrantFiled: April 16, 2018Date of Patent: May 21, 2019Assignee: 3Y POWER TECHNOLOGY (TAIWAN), INC.Inventors: Shao-Feng Lu, Chuan-Kai Wang
