Mobile communication antenna

Abstract

The invention discloses a mobile communication antenna. The mobile communication antenna comprises a mobile phone main shell, a fixed bottom plate is fixedly connected to the edge of the bottom end of the inner surface of the mobile phone main shell, connecting mechanisms are fixedly connected to the front end and the rear end of the outer surface of the upper end of the fixed bottom plate, each connecting mechanism comprises a plurality of first connecting plates, a clamping rod, a limiting block, a first sliding groove, a first spring, a second connecting plate, a first clamping groove and an inclined groove, wherein the first connecting plates are fixedly connected to the front end and the rear end of the outer surface of the upper end of the fixed bottom plate. By means of the connecting mechanisms and a dismounting mechanism, a circuit board and a built-in antenna can be dismounted and mounted conveniently; a clamping block and a through groove are adopted, the clamping block and the through groove are matched with the dismounting mechanism so as to be used, so that a shielding cover can be dismounted conveniently, workers can perform maintenance conveniently; and an external antenna and the built-in antenna are communicated through a connecting terminal, and therefore, the purpose of enhancing signals is achieved, and a user can use the mobile communication antenna conveniently.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a mobile communication antenna. Background technique [0002] The mobile terminal antenna refers to the antenna installed on the mobile terminal equipment, which is used to complete the reception and transmission of air signals. With the development of science and technology, external antennas are gradually being eliminated, and various wireless device manufacturers have adopted FPC internal antennas. [0003] A Chinese patent discloses an antenna for a mobile communication terminal. The patent application number is CN202020377977.6, which includes a built-in antenna. The bottom of the board is glued with double-sided tape, and the end of the built-in antenna away from the FPC board is connected to a fixed tube, which is fixedly socketed with the built-in antenna, and the end of the fixed tube close to the built-in antenna is connected to a spring, and the spring is...

AI Technical Summary

Problems solved by technology

[0004] The above comparative patent uses double-sided adhesive to tear off the adhesive paper on the FPC board, and uses the double-sided adhesive to directly adhere to the PCB board of the wireless device, which is convenient for installation, but when the built-in antenna or the internal components of the FPC board are damaged , it needs to be disassembled, repaired and replaced. The method of fixing the FPC board through double-sided adhesive bonding is not convenient for disassembling the FPC and the internal antenna, which brings inconvenience to the maintenance personnel. A shielding cover is added on the outside to prevent electromagnetic interference, and it can shield the components on the PCB board and the LCM. When the electronic components are damaged and need to be repaired, the shielding cover needs to be removed, but because the existing shielding cover is generally directly bonded to the circuit board It is not easy to disassemble, which makes maintenance inconvenient. The signal received by the built-in antenna is limited. When the user uses the mobile phone outdoors with poor signal, the signal received by the mobile phone will be poor or even no signal, which will affect the normal use of the mobile phone
