WIPO Patent Application WO/2020/252851
Kind Code:
A1
Abstract:
A ceramic composite middle frame of a mobile terminal and a manufacturing method therefor. The ceramic composite middle frame of the mobile terminal comprises a ceramic frame (1) and a metal middle plate (2), the ceramic frame (1) is connected to the metal middle plate (2) by means of a plastic framework (3), the metal middle plate (2) and the ceramic frame (1) are provided with lapping structures, two sides of the plastic framework (3) are provided with engagement structures, the engagement structure at one side of the plastic framework (3) is connected to the lapping structure of the ceramic frame (1), and the engagement structure at the other side of the plastic framework (3) is connected to the lapping structure of the metal middle plate (2). The ceramic composite middle frame is formed by performing in-mold injection molding on the ceramic frame (1) and the metal middle plate (2). The middle frame is sparkling and crystal-clear in appearance and is hard and durable, and can realize local metallization inside the ceramic frame (1) according to antenna design requirements, thereby facilitating antenna design and layout, and the middle frame has a good texture and effect as a whole.
