DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Refer to FIG. 1. FIG. 1 illustrates an explosion drawing of an embodiment of a wireless network card of the invention. The wireless network card 100 includes a wireless network card body 110 and an antenna 120. A rotational angle between the wireless network card body 110 and the antenna 120 needs to be adjusted to fit different locations to receive better signals. Thus, there is a need for a wireless network card antenna position structure to position the antenna 120 and fix the rotational angle between the antenna 120 and the wireless network card body 110 when the rotational angle is adjusted.
Refer to FIG. 1 and FIG. 2 simultaneously. FIG. 2 is a schematic drawing of an embodiment of the wireless network card antenna position structure of the invention. The wireless network card antenna position structure for securing the antenna 120 at the rotational angle with respect to the wireless network card body 110 includes a sunk position piece 130 and a salient position piece 140. The sunk position piece 130 and the salient position piece 140 are disposed between the antenna 120 and the wireless network card body 110. The sunk position piece 130 is fixed on a surface between the antenna 120 and the wireless network card body 110. The salient position piece 140 is fixed on another surface between the antenna 120 and the wireless network card body 110. In this embodiment, the sunk position piece 130 is fixed on the antenna 120, and the salient position piece 140 is fixed on the wireless network card body 110. In another embodiment, the sunk position piece 130 may be fixed on the wireless network card body 110, and the salient position piece 140 may be fixed on the antenna 120. The sunk position piece 130 includes a plurality of sunk points 132, and the salient position piece 140 includes at least one salient point 142. The salient point 142 may couple with at least one of the sunk points 132 to fix the rotational angle when the rotational angle between the antenna 120 and the wireless network card body 110 is adjusted. The material of the sunk position piece 130 and the salient position piece 140 may be a metal, which is stronger and more resistant to abrasions than plastic. Thus, the wireless network card antenna position structure life may be increased.
The sunk position piece 130 in the embodiment may be a copper pillar fixed in the antenna 120. The sunk points 132 may be disposed circularly on a surface face the wireless network card body 110 of the sunk position piece 130. An angle between the adjacent sunk points 132 is about 30 degrees.
Refer to FIG. 3. FIG. 3 illustrates an explosion drawing of another embodiment of the wireless network card of the invention. There are two of the salient points 142 on the salient position piece 140. The salient points 142 are disposed on two opposite sides of the salient position piece 140 for better balance. The material of the salient position piece 140 may be a beryllium-copper alloy. The salient position piece 140 may have a surface treatment, such as electroplating, for increasing smoothness of the salient points 142.
Refer to FIG. 2 and FIG. 3 simultaneously. The antenna 120 includes an extended portion 122. The extended portion 122 is extended from the copper pillar of the sunk position piece 130. The sunk points 132 may surround the extended portion 122. The wireless network card body 110 has an antenna opening 112 facing the antenna 120. The extended portion 122 of the antenna 120 may be inserted into the antenna opening 112. The material of the extended portion 122 may be a copper. The frictional force generated from the extended portion 122 in contact with a cylinder wall of the antenna opening 112 may stably retain the extended portion 122 in the antenna opening 112.
The salient position piece 140 may also include the antenna opening 112, and the salient points 142 are disposed around the antenna opening 112. The extended portion 122 of the antenna 120 may have a flange 124. The flange 124 is disposed on a section of the extended portion 122 in the wireless network card body 110 and the flange 124 is in contact with the antenna opening 112. The extended portion 122 may further include a retaining ring 126 disposed in the flange 124. The retaining ring 126 may be in contact with the cylinder wall of the antenna opening 112 to prevent the extended portion 122 departing from the antenna opening 112 of the wireless network card body 110. The retaining ring 126 may be an E-shaped retaining ring or a C-shaped retaining ring.
The wireless network card antenna position structure may fix the rotational angle between the antenna and the wireless network card body by coupling the salient points and the sunk points when the rotational angle is adjusted.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
