After the processing, the frame body 10 is placed in an injection mold, and the protective member 20 is injection molded in the frame body 10 by injection molding, so that the processing of the portable electronic device housing 100 can be completed.
[0055] The portable electronic device housing 100 provided in the present application comprises an inner frame 11 and an outer frame 12 combined to form a frame body 10, the inner frame 11 is provided with a first through hole 111, the outer frame 12 is provided with a second through hole 121, a protective member 20 is provided in the first through hole 111 and the second through hole 121, the protective member 20 is connected to both the inner frame 11 and the outer frame 12, and covers the connection between the inner frame 11 and the outer frame 12. In this way, when the electrolyte enters the second through hole 121, it will not contact the inner frame 11 and the outer frame 12 at the same time, thereby avoiding electrochemical reaction and corrosion. The inner frame 11 is provided with a first groove 112, the outer frame 12 is provided with a second groove 122, and the protective member 20 is provided with a first protrusion 22 corresponding to the first groove 112, and a second protrusion 23 corresponding to the second groove 122.

In this way, the protective member 20 can be shielded by the stopper 123, and when installing external structures such as card trays and buttons, it can be avoided to directly hit the protective member 20 during the insertion process, thereby damaging the protective member 20. At the same time, the stopper 123 can cover the protective member 20, improve the consistency of the appearance of the frame 10, and improve the aesthetics of the electronic product.

In this way, the stopper 123 can completely cover the protective member 20, thereby improving the protective effect on the protective member 20. The fourth through hole 1231 has the same cross-sectional shape as the third through hole 21, so that the fourth through hole 1231 and the third through hole 21 are connected to each other for accommodating other components.
