Blank assembly of shell, shell, manufacture method of shell and terminal

Abstract

The invention discloses a blank assembly of shell, a shell, a manufacture method of the shell and a terminal. The blank assembly comprises a first blank, a second blank and a filling layer; a gap penetrating in the thickness direction of the first blank is formed in the first blank, part of the second blank stretches into the gap, the portion, located in the gap, of the outer surface of the second blank is separated from the inner wall of the gap, and the gap is filled with the filling layer. According to the blank assembly, by stretching part of the second blank into the gap, and by filling the gap with the filling materials, the part, located in the gap, of the second blank is connected with the first blank are connected, and part of the second blank can be installed in the gap in an embedded mode. During the subsequent machining process, the part, located outside of the gap, of the second blank can be cut and further machined into the shell, and thus, the blank assembly can be machined into the terminal shell; and consequently, the manufacturing procedure of the shell is simplified, the yield of the shell is increased, and production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, and in particular, to a shell blank assembly, a shell, a manufacturing method of the shell, and a terminal. Background technique [0002] In the related art, in order to solve the problem of antenna performance for mobile phones with all-metal frames, one or more slits are usually opened on the metal frame, and tiny metal strips are filled in the opened slits to form a micro-slit structure. For structurally designed antennas, when human hands or other parts of the human body are in close contact with the micro-slit strip, the performance of the antenna will be greatly affected, and the performance of the antenna will be greatly deteriorated. [0003] In the micro-slit processing process, the micro-slit antenna slot can be processed by CNC first, and finally the antenna slot can be filled with glue to achieve the appearance. However, this micro-seam processing method has p...

AI Technical Summary

Problems solved by technology

However, this micro-slit processing method has problems such as high cost of micro-slit filling process, low reliability of nano-injection molding compared with the combination of glue and metal, and poor mass production in CNN processing.
