This Application claims priority of Taiwan Patent Application No. 97112996, filed on Apr. 10, 2008, the entirety of which is incorporated by reference herein.
1. Field of the Invention
The invention relates to an electronic device and a telescopic antenna module.
2. Description of the Related Art
A conventional telescopic antenna module comprises an antenna and a telescopic support. During assembly of the conventional telescopic antenna module with an electronic device including a metal shell, a ground terminal is connected to the metal shell via the metal shell for ground connection. Meanwhile, if the conventional telescopic antenna module is applied to an electronic device with a plastic shell, the electronic device additionally comprises a metal ground terminal and a copper foil built thereon because the plastic shell does not provide ground connection. Specifically, the copper foil is connected to the metal ground terminal and the ground terminal of the antenna. The copper foil enables the ground terminal of the antenna to connect to the metal ground terminal of the electronic device for ground connection.
However, if the conventional telescopic antenna module is assembled with electronic devices with various materials, the structures of the electronic devices are re-designed according to their specific material, resulting in design inconvenience. Moreover, costs are substantially increased as different designs need additional molding and copper foil.
The invention provides an electronic device and a telescopic antenna module. The electronic device includes a housing and the telescopic antenna module. The telescopic antenna module includes an antenna with a ground terminal, a telescopic support with a sliding mechanism and an antenna module shell. The antenna is movably connected to the sliding mechanism. The antenna module shell is made of conductive material. The length of the antenna module shell ranges between 130 mm and 200 mm, and the width of the antenna module shell ranges between 35 mm and 50 mm. The antenna is connected to the antenna module shell via the ground terminal for ground connection.
Note that the telescopic support further comprises a hole. The ground terminal passes through the hole and is then connected to the antenna module shell.
Note that the ground terminal comprises a metal flexible sheet.
Note that the antenna further comprises a first signal contact. The telescopic support further comprises a second signal contact. The first signal contact maintains connection with the second signal contact during movement of the antenna corresponding to the telescopic support.
Note that the antenna module shell comprises a fixed hole. The telescopic support further comprises a fastened hole. The antenna module shell is connected to the telescopic support via the fixed hole and the fastened hole.
Note that the antenna module shell comprises a ground protrusion. The ground protrusion is connected to the ground terminal of the antenna.
The electronic device comprises a housing and the above-mentioned telescopic antenna module.

b is a schematic view from another angle of showing assembly of a telescopic antenna module according to an embodiment of the invention.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
Referring to
The telescopic support 23 comprises a sliding mechanism 231, a second signal contact 233, a hole 232 and two fastened holes 234 and 235. The antenna 22 is movably disposed on the sliding mechanism 231. When the antenna 22 reverts back to the sliding mechanism 231, the ground terminal 221 of the antenna 22 protrudes from the hole 232 and then connects to the antenna module shell 21 (shown in
Referring to
The telescopic antenna module 20 independently provides ground connection, thus, the telescopic antenna module 20 can be directly assembled with the electronic device with various materials, without consideration of ground connection, and without changing the structure of the electronic device, thus decreasing costs.
While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
