Antenna feeding device and mobile communication terminal with the same

Abstract

Disclosed is an antenna feeding device belonging to the component range of the mobile communication terminal and mobile communication terminal positioning the antenna feeding device. The antenna feeding device includes the following parts: an antenna used for receiving / transmitting the electric wave; an antenna interconnecting piece formed on the circuit board to connect with the antenna; a connecting element in the electrical connector between the antenna and the circuit board with one end fixed on the antenna and the other end on the antenna interconnecting piece. The invention can reduce the electromotive force loss caused by the lengthened feed line for spring contact with the circuit board in the existing art and increase the contacting area, meanwhile, the invention adopts the same fixed point to eliminate the feed line deviation between the productions to ensure the more stable fixed acting force. When the antenna is stably fixed on the circuit board, the antenna is electrically connected with the circuit board, which can not cause the damage to the circuit board.

Description

technical field [0001] The present invention belongs to the scope of components of mobile communication terminals, and more specifically relates to an antenna feeding device and a mobile communication terminal provided with the antenna feeding device. In the present invention, while the antenna can be stably fixed on the circuit board, the Its electrical connection to the circuit board does not constitute a loss to said circuit board. Background technique [0002] In general, a mobile communication terminal is an essential device for transmitting and receiving radio waves with an adjacent base station, and thus is equipped with an antenna. [0003] Antennas used in mobile communication terminals are classified into external (external) and internal (internal antenna; intenna) types according to the installation location. The above-mentioned antennas include a receiving part that receives radio signals with a certain pattern, or conversely, transmits radio waves The transmitt...

AI Technical Summary

Problems solved by technology

[0010] However, in the feeding device of the above-mentioned prior art antenna, because the elasticity of the above-mentioned feeder wires 22, 42 naturally becomes weaker with time and the use environment, this will make the contact pressure provided to the above-mentioned antenna connecting parts 13, 33 in an insignificant range. stable state

Moreover, the above-mentioned feeder lines 22, 42 are each formed into a curved shape for generating elastic force, so that the above-mentioned feeder lines 22, 42 themselves may lose electromotive force, and due to the contact area between the above-mentioned feeder lines 22, 42 and the antenna connection parts 13, 33 narrower, which will also cause a loss of EMF

[0011] Moreover, since the above-mentioned feeder lines 22, 42 form a three-dimensional space shape in an elongated state, the positions of the contact points on the above-mentioned antenna connecting parts 13, 33 may vary according to the assembled state, which is not conducive to homogeneous product quantity. production operation
