Antenna power supply device of sliding-lid type mobile communication terminal

Abstract

The invention discloses an antenna power supply device for a sliding cover type mobile communication terminal. The antenna is located on the display cover in front of the terminal, which can also prevent the damage of the antenna power supply device connecting the antenna and the transceiver and the resulting deterioration of the operating characteristics. decline. The slide-type mobile communication terminal includes a first frame, a second frame and an antenna, and is characterized in that the antenna power supply device includes: a strip antenna connection pad, a power supply rod and a power supply protrusion, wherein the strip antenna connection pad is along the The sliding direction of the above-mentioned second frame is located on the above-mentioned circuit board in a strip shape and connected with the above-mentioned wireless transceiver; the power supply rod is extended along the sliding direction of the above-mentioned second frame and connected with the above-mentioned The antennas are connected; the power supply protrusion protrudes from the power supply rod, and moves along the sliding direction of the second frame in a state of contacting the strip antenna connection pad.

Description

technical field [0001] The present invention relates to an antenna power supply device for a mobile communication terminal, in particular to an antenna power supply device for a slide-type mobile communication terminal. Damage to the power supply unit and the resulting reduction in operating characteristics. Background technique [0002] A mobile communication terminal (hereinafter referred to as "terminal") generally refers to a mobile phone or a PDA, which transmits or receives signals with a base station installed near the terminal to transmit information with a specific party and perform various additional services. [0003] Therefore, the terminal is equipped with an antenna for signal transmission and reception. Moreover, a wireless transceiver is installed on the circuit board built in the terminal body, and an antenna power supply device for connecting the wireless transceiver and the antenna is also provided. [0004] The antenna power supply device for the antenn...

AI Technical Summary

Problems solved by technology

However, if the power supply method is used to connect the wireless transceiver installed on the circuit board in the body and the antenna on the display cover through a cable, the cable is likely to be twisted or twisted when the display cover sliding along the body moves repeatedly. Rubbing against the case of the body or display cover, which can easily damage the cable

[0007] Therefore, the power supply method of installing the antenna on the display cover of the slide type terminal and connecting the antenna to the transceiver on the circuit board inside the fuselage through a cable cannot be applied.
