## Background
BACKGROUND
1. Technical Field
The disclosure generally relates to electronic wireless communication receivers, particularly to an electronic wireless communication receiver used with computers.
2. Description of Related Art
With development of wireless communication technology, wireless communication receivers are widely used for electronic devices such as computers. Commonly, a wireless communication receiver includes a main body and a cover. The cover is detachably assembled to the main body. When the wireless communication receiver is used to receive wireless communication signals for a computer, the cover is detached from the main body, and then the main body is connected to the computer. However, the cover separated from the main body may be easily lost.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
Referring to FIG. 1, a wireless communication receiver 100, according to one exemplary embodiment, includes a main body 10, a cover 20, an antenna 30, and a sleeve 40. The cover 20 is slideably connected to the main body 10 between open and closed positions by the antenna 30. The sleeve 40 is placed around the antenna 30.
The main body 10 includes a housing 11, a latching portion 12, a Universal Serial Bus (USB) connector 13, two opposing protrusions 14, and a receiving portion 15. The housing 11 includes two opposing first flat surfaces 111 and two opposing first side surfaces 112 connecting the two first flat surfaces 111. Electrical elements (not shown) received in housing 11 support operation of the wireless communication receiver 100. A recess 16 is defined in each first surface 111 with a positioning hole 161 therein. The latching portion 12 extends from one end of the housing portion 11 to engage with the cover 20. The USB connector 13 protrudes from the latching portion 12 to connect to other electronic device such as a computer. The two protrusions 14 protrude from the two side surfaces 112 respectively and are adjacent to the latching portion 12. A mounting hole 142 is defined in each protrusion 14. The receiving portion 15 is substantially a hollow cylinder located at one side surface 112, and communicates with a corresponding mounting hole 142 to partially receive the antenna 30.
The cover 20 includes a cap 22, two protrusions 24, and two supporting portions 26. The cap 22, which includes two second flat surfaces 222 and two second side surfaces 224 connecting the two second flat surfaces 222 to each other, corresponds to the housing 11. A receiving cavity 28 with an opening is defined in one end of the cap 22 to receive the USB connector 13 and engage with the latching portion 12. The two protrusions 24 respectively protrude from the two side surfaces 224 of the cap 22 and are adjacent to one end of the cap 22, and correspond to the two protrusions 14 of the main body 10. A mounting hole 242 is defined in each protrusion 24. The two supporting portions 26 extend from an edge of each second flat surface 222 of the cover 20, corresponding to the recess 16 and the positioning holes 161.
The antenna 30 includes a connecting end 31 and a radiating portion 32 extending from the connecting end 31. The connecting end 31 extends through one of the mounting holes 242, and is received in its corresponding mounting hole 142 to electrically connect to the electrical elements in the housing portion 11. The radiating portion 32 extends through the mounting holes 242 of the cover 20 and the opposing mounting holes 142, and connects the cover 20 to the main body 10. A distal end of the radiating portion 32 is received in the receiving portion 15 of the main body 10. The radiating portion 32 may be made of flexible material.
The sleeve 40 is a hollow pipe made of flexible material. The sleeve 40 surrounds at least a part of the antenna 30 to protect the antenna 30.
Referring to FIGS. 2 and 3, in assembly, firstly, the connecting end 31 of the antenna 30 is received in one of the mounting holes 142. Then, the radiating portion 32 is extended through one of the mounting holes 242 of the cover 20, and extended through the opposing mounting holes 142 with the sleeve 40 placed around the radiating portion 32. After that, the radiating portion 32 extends through the opposing mounting hole 242 and a distal end of the radiating portion 32 is partially received in the receiving portion 15 of the main body 10. Finally, the cover 20 is slid toward the main body 10 and the closed position until the USB connector 13 is received in the receiving cavity 28 and the latching portion 12 is engaged in the receiving cavity 28.
In other embodiments, two ends of the sleeve 40 can be extended through the mounting holes 242 and fixed in the mounting holes 142. Therefore, the cover 20 is slideably connected to main body 10 via the sleeve 40 and the antenna 30 together. In addition, the positions of the positioning hole 161 and the supporting portion 26 located in the main body 10 and length of the radiating portion 32 can be changed to improve performances of the antenna 30.
Referring to FIG. 4, to use the wireless communication receiver 100 with a computer (not shown), the cover 20 is detached from the main body 10, and then slid away from the main body 10 along the sleeve 40 and antenna 30 towards the open position. The sleeve 40 and antenna 30 are resiliently bent relative to the main body 10 together with the cover 20. One supporting portion 26 is inserted in the positioning hole 161 to maintain the cover 20 in the open position to expose the USB surface 13 from the cover 20 so that it can be received in a USB connector.
It is believed that the exemplary embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
