Fingerprint identification module, terminal device and assembling method

Abstract

The present invention provides a fingerprint identification module, a terminal device and an assembling method, and relates to the design field of the fingerprint module of the terminal device. The invention aims to solve the stack design problem of the structure of the terminal device due to the fact that the internal structural space of the terminal device is occupied by one part of the fingerprint identification module in the prior art. The fingerprint identification module comprises a fingerprint chip, a fingerprint cover plate, a flexible circuit board, a reinforcing plate and a decorative ring arranged at the periphery of the fingerprint chip. The first connection part of the decorative ring is connected with the first end of the fingerprint chip and is also in contact connection with the fingerprint cover plate. The second connection part of the decorative ring is connected with the second end of the fingerprint chip and is also in contact connection with the fingerprint cover plate. Meanwhile, the second connection part of the decorative ring is fixedly connected with the reinforcing plate. The present invention also provides a terminal device and an assembling method. According to the technical scheme of the invention, the second connection part of the decorative ring is fixedly connected with the reinforcing plate. Therefore, fingerprint identification module becomes thinner in thickness. The internal structural space of the terminal device is saved when the fingerprint identification module is installed through being matched with the terminal device.
