Abstract

The invention discloses a photosensitive device fixing structure and a mobile terminal. The photosensitive device fixing structure comprises a mainboard upper cover and a FPC (Flexible Printed Circuit) assembly fixed to the mainboard upper cover, wherein the FPC assembly comprises a reinforcement plate, a photosensitive device directly fixed to the reinforcement plate, a first locating mounting part arranged on the reinforcement plate, and a seal sleeve arranged on the photosensitive device in a sleeving manner; and the FPC assembly is fixed to the mainboard upper cover through the locating mounting part. The FPC assembly of the mobile terminal is fixed to the mainboard upper cover, the photosensitive device is directly fixed to the reinforcement plate of the FPC assembly to serve as a part of the FPC assembly, and the FPC assembly can be fixed with the mainboard upper cover without a mounting bracket, so that a dimension chain of assembling of the photosensitive device is shortened; and an accumulated tolerance is reduced for improving the consistency of detection performance of the photosensitive device. In addition, the seal sleeve is arranged outside the photosensitive device in a sleeving manner, so that the mobile terminal has waterproof performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fixed structure of a photosensitive device and a mobile terminal. Background technique [0002] With the rapid development of smart mobile terminals, smart phones have become a necessity in people's daily life. At the same time, high-frequency use puts forward higher requirements on the reliability of mobile phones, especially the waterproof performance of electronic devices. For example, in rainy days, humid environments, sweating during exercise, etc., electronic devices may lose their functions due to inflow of liquid. . [0003] Photosensitive devices are very important detection components on smartphones, and their assembly effect is of great significance to the overall performance of smartphones. In the prior art, the following two methods are often used for the assembly of the photosensitive device: Method 1. The photosensitive device is assembled on the main boa...
