Abstract

The invention discloses a fingerprint sensor component used in a terminal and a terminal provided with the same. The fingerprint sensor component comprises a decorative ring, a fingerprint chip, and sealant. A mounting hole is defined by the inner ring of the decorative ring; the decorative ring is provided with a first annular recess; the fingerprint chip is assembled inside the mounting hole; the fingerprint chip is provided with a second annular recess; the second annular recess is communicated with the first annular recess for jointly defining an annular sealant groove; the sealant is filled in the annular sealant groove for sealing the annular space between the mounting hole and the fingerprint chip. According to the fingerprint sensor component used in a terminal, liquid is prevented from entering in the inner side of the fingerprint chip through the annular space between the mounting hole and the fingerprint chip, and therefore, fillet weld legs of the fingerprint chip are prevented from being corroded by liquids and short circuit failure is prevented; the annular sealant groove is set to dispense sealant for waterproofing; therefore, the processing and assembling difficulty of the decorative ring and the fingerprint chip can be reduced to make the structure of the fingerprint sensor component more compact and exquisite.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a fingerprint sensing component for a terminal and a terminal with the same. Background technique [0002] More and more mobile terminals have been equipped with fingerprint sensing components. The fingerprint sensing component is usually composed of a metal decorative ring and a fingerprint chip. After the decorative ring and the fingerprint chip are assembled together, there will be a gap of 0.05mm between the decorative ring and the fingerprint chip. With a fitting gap of 0.2mm, during the normal use of the mobile phone terminal, liquids such as water or sweat will enter the interior of the fingerprint sensor component along the fitting gap, corroding the solder pins of the fingerprint chip, causing the fingerprint chip to short circuit or fail, and the matching gap It affects the overall aesthetics of the mobile terminal, and there are often problems such as dust accumu...
