Antenna module group

Abstract

The invention relates to an antenna module group mainly comprising a printed circuit board, a plurality of conductive clamp elements, and an antenna. All the conductive clamp elements are arranged at the printed circuit board and each conductive clamp element has two opposite elastic clamp arms. The antenna can be plugged between the elastic clamp arms of the conductive clamp elements by a detachable way. Therefore, assembling of the antenna with the printed circuit board can be realized by the conductive clamp elements, and with utilization of the conductive clamp elements, the signal feeding and grounding can be realized, so that effects of convenient assembling and disassembling and the configuration elasticity enhancement can be realized.

Description

Technical field [0001] The present invention relates to an antenna used in a handheld electronic device, and in particular refers to an antenna module that uses a conductive clip as the feed point and / or ground point of the antenna while providing a fixed clamping function. Background technique [0002] Generally speaking, handheld electronic devices, such as portable bar code scanners, require an antenna to be installed inside the body to transmit and receive wireless signals. The traditional antenna is set up by multiple contact metal shrapnel or multiple conductive foams fixed to the printed circuit board with Surface Mount Technology (SMT), so that the antenna can pass through the contact metal shrapnel or conductive foam. Touch to complete the electrical conduction with the printed circuit board, and then complete the feeding and grounding of the antenna signal. [0003] However, as for the contact metal shrapnel first, the contact metal shrapnel is prone to elastic deformati...

Problems solved by technology

[0003] However, as far as the contact metal shrapnel is concerned, the contact metal shrapnel is prone to elastic deformation under long-term stress, which will cause poor contact between the printed circuit board and the antenna, and the conductive foam itself is easy to dissipate from the printed circuit board If it falls off, it will also affect the electrical conduction effect between the printed circuit board and the antenna

Moreover, in order to fix the antenna itself, the printed circuit board must also be provided with a plurality of screw holes to match the screws to fix the antenna itself or the supporting seat to which the antenna is attached. These screw hole posts will occupy too much space and limit the space of the printed circuit board. In addition to the circuit design, it is also easy to cause the printed circuit board to be broken during the installation process, which will increase the manufacturing cost; therefore, no matter whether it is a contact metal shrapnel or a conductive foam, there is no way to provide good electrical power to the antenna.
