Shell of electronic product and installation method of fingerprint module

Abstract

The embodiment of the invention relates to the field of electronic products, and discloses a shell of an electronic product and an installation method of a fingerprint module. The shell of the electronic product is provided with a mounting groove for mounting the fingerprint module, an accommodating groove for accommodating a flexible circuit board of the fingerprint module, and a notch for allowing the flexible circuit board of the accommodated fingerprint module to pass through, wherein the accommodating groove is connected with the mounting groove, and the accommodating groove extends to the notch. The notch is located at the side edge of the shell of the electronic product. The shell of the electronic product enables the fingerprint module to be convenient to assemble and easy to disassemble, the fingerprint module can be installed and used again after being disassembled, and the manufacturing cost is relatively low.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic products, and in particular to a casing of the electronic product and a method for installing a fingerprint module. Background technique [0002] At present, there are two main ways to install the fingerprint module of electronic products. One is to make the FPC (flexible circuit board) of the fingerprint module very long, and snap the BTB (board-to-board connector) of the fingerprint module together. After it is on the main board, reserve adhesive around the casing, glue the fingerprint module on the casing, and finally splice the casing carefully. There is also a method of bonding the back glue of the fingerprint module to the shell first, passing the FPC through the gap of the shell, and then placing the BTB on the FPC on the positioning foam of the shell, and then assembling the BTB to fasten the shell. [0003] The inventor found that in the first assembly method, the FPC ...

Problems solved by technology

[0003] The inventor found that in the first assembly method, the FPC needs to be very long, difficult to assemble and costly. When disassembling, the fingerprint module must be buckled from the back glue on the battery cover, and the FPC of the fingerprint module is easy to break , it is very difficult to disassemble. After disassembly, the back glue is easy to wrinkle and is not easy to reuse; and the second assembly method, because the fingerprint module has been glued to the shell, resulting in the integration of the BTB and the shell, and the BTB assembly must be blindly buckled. The assembly is difficult, and it is easy to cause the BTB assembly and pressing to not be in place, resulting in the failure of the fingerprint module function
