Abstract

The invention discloses a mobile terminal and a connecting structure of a universal serial bus connector thereof. The mobile terminal comprises a body, a mainboard arranged in the body, and an antennaarranged at the bottom of the body, the universal serial bus connector is arranged at the bottom of the body and fixedly arranged on the mainboard, a signal line of the universal serial bus connectoris connected with a signal point of the mainboard, a metal housing of the universal serial bus connector is connected with a grounding point of the mainboard through a first filtering module, and thefirst filtering module has a low impedance in a frequency band range of universal serial bus signals and has a high impedance in a frequency band range of antenna signals. According to the technicalscheme, the first filtering module is arranged between the metal housing of the universal serial bus connector and the grounding point of the mainboard of the mobile terminal, effective shielding of the universal serial bus signals is realized, and the influence of the metal housing of the universal serial bus connector on the performance of the antenna can be effectively reduced.

Description

technical field [0001] The invention relates to the field of terminals, in particular to a mobile terminal and a connection structure of a Universal Serial Bus (Universal Serial Bus, USB) connector thereof. Background technique [0002] The universal serial bus connector is an essential component of a mobile terminal, and its function is to communicate and connect the mobile terminal with other devices or to charge the mobile terminal. [0003] In order to enhance the reliability and durability of the universal serial bus connector, the universal serial bus connector is generally a metal shell. Usually, the metal shell of the USB connector is directly connected to the grounding point of the mainboard of the mobile terminal, so as to enhance the shielding performance of the USB connector to the USB signal. [0004] Generally, for the convenience of use and the appearance of the mobile terminal, the USB connector is preferably placed in the middle of the bottom of the mobile ...
