▎ 摘　　要

NOVELTY - The charger has middle frame (1), a surface housing (2), and a circuit board component (3). The middle frame is provided with a mounting groove (11). The circuit board component is arranged in the mounting groove. The middle frame is provided with a metal pin. The metal pin is extended into the mounting groove and is connected to the circuit board component. The connection interface is provided on the circuit board component. The outer side of the middle frame is provided with interface avoidance hole (71) penetrating into the mounting groove. The first graphene fin is located above the mounting groove. The first graphene fin is provided corresponding to the upper side of the circuit board component. USE - Charger for smart mobile phone. ADVANTAGE - The charger has better radiating performance, under the continuous use condition, can avoid the high temperature, and improve the reliability. The service life of the upper component is enhanced, so that the charger has higher reliability. The first connecting portion and the second connecting portion are made of metal elastic portions. The mounting of the assembly and the connection of the metal inserting are more convenient. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of the charger with good radiating performance. 1Middle frame 2Surface housing 3Circuit board component 4Containing metal pin 5First graphene fin 7Bottom housing 11Mounting groove 71Interface avoiding hole
