Abstract: A connector is provided including an insulating body and a plurality of power terminal components. Each of the power terminal components includes a power terminal and an extension portion. The power terminal is inserted into the insulating body. The extension portion protrudes at a rear end of the power terminal in a projecting manner, wherein the extension portion protrudes out of the insulating body. During operation of the connector, current flows from the extension portion to the connector through the power terminal, or flows from the connector to the extension portion through the power terminal. As the extension portion increases a contact area for transmitting electrical power, power loss during electrical power transmission and heat generated in a circuit board in existing connector structures are reduced, thereby extending service life of the connector. A power supply having the connector is also provided.

Abstract: 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.

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.
