Abstract
The utility model discloses the wiring structure of a power adapter, which comprises a circuit board, metal connecting elastic sheets, a bottom cover and plug-in pins. The wiring structure of the power adapter has the advantages of being artful and reasonable in structural design. The plug-in pins are riveted to the metal connecting elastic sheets, wherein the plug-in pins and the metal connecting elastic sheets, the plug-in pins and the metal connecting elastic sheets are connected stably and matched tightly. The metal connecting elastic sheets are provided with elastic contact pins, thus having a certain elastic force. Meanwhile, the metal connecting elastic sheets are positioned by contact recesses on the circuit board, thus being accurately abutted against metal jumper wires on the circuit board. Therefore, the condition that due to the inaccurate alignment, the normal combination or the current conduction cannot be realized can be avoided. The metal connecting elastic sheets and the circuit board are facilitated to tightly and stably match with each other, so that the electrical conductivity is greatly improved. In addition, the wiring structure of the power adapter has the advantages of simple and compact integral structure, easy realization and low cost and is favorable for wide popularization and application.
