[0022] See also Figure 1-Figure 4 , the utility model provides a mini wireless network card.

[0023] The wireless network card is a terminal wireless network device, which is a terminal that uses wireless signals for data transmission without wired connection. When the mini wireless network card is in use, it has a protective cover to protect the USB plug. However, the protective cover box and the mini wireless network card shell are connected by snap connection, which often causes the problem of loosening and falling off during carrying, resulting in wear of the USB plug and reducing the service life of the mini wireless network card. At the same time, the protective cover is connected to the wireless network card shell, which is not easy to cause the protective cover to be lost or dropped during carrying and use. Therefore, it needs to be improved, which includes a wireless network card body 100, a protective cover 200 for protecting the left end of the wireless network card body 100 is provided at the left end of the wireless network card body 100, and a connecting device 300 for connecting the protective cover 200 to protect the left end of the wireless network card body 100 is provided on the front and rear side walls of the wireless network card body 100;

[0024] The left end of the wireless network card body 100 is provided with a USB plug 101 for plugging into a computer, and the right end of the wireless network card body 100 is fixedly installed with a fixing plug 102 for plugging and fixing the protective cover 200, so that the protective cover 200 removed from the USB plug 101 can be easily inserted into the fixing plug 102 to prevent the protective cover 200 from being lost or damaged by collision when the wireless network card body 100 is in use;

[0025] The protective cover 200 has a fixed block 201 fixedly mounted on the cover body thereof for being fixedly connected to the second telescopic rod 320. There are two fixed blocks 201, which are symmetrically distributed on the front and rear walls of the protective cover 200, so that the protective cover 200 can be easily removed from the USB plug 101 through the fixed connection between the second telescopic rod 320 and the fixed blocks 201.

[0026] The connecting device 300 includes a telescopic rod 1 310 movably connected to the wall of the wireless network card body 100, and the telescopic rod 1 310 is movably connected to the wall of the wireless network card body 100 through a hinge rod, so that the telescopic rod 1 310 can be easily rotated, so that the protective cover 200 removed from the USB plug 101 can be inserted into the fixed plug 102; a telescopic rod 2 320 for telescoping is arranged in the rod body of the telescopic rod 1 310, and the end of the telescopic rod 2 320 away from the telescopic rod 1 310 is connected to the fixed block 201 on the protective cover 200, and the upper and lower ends of the telescopic rod 1 310 are connected to the fixed block 201 on the protective cover 200. A locking assembly 330 is provided for locking the second telescopic rod 320 to prevent the second telescopic rod 320 from being extended and retracted. When the operator needs to remove the protective cover 200 from the USB plug 101, the locking assembly 300 is first used to cancel the locking of the second telescopic rod 320. At this time, the second telescopic rod 320 can be extended and retracted left and right in the first telescopic rod 310. At this time, the protective cover 200 can be removed from the USB plug 101, and then the second telescopic rod 320 is rotated to insert the protective cover 200 into the fixed plug 102. Finally, the second telescopic rod 320 is locked by the locking assembly 330.

[0027] A telescopic cavity 311 is provided in the body of the telescopic rod 1 310 for facilitating the telescopic rod 2 320 to telescope left and right, and the telescopic cavity 311 is in a stepped shape. A limiting plate 321 is fixedly installed at the right end of the telescopic rod 2 320 to prevent the telescopic rod 2 320 from escaping from the telescopic cavity 311, thereby preventing the telescopic rod 2 320 from escaping from the telescopic cavity 311;

[0028] The locking assembly 330 includes a clamping plate 334 disposed in the cavity of the telescopic cavity 311 for clamping the rod body of the telescopic rod 2 320, and a screw 333 for driving the clamping plate 334 to move up and down is disposed at the bottom of the clamping plate 334 away from the telescopic rod 1 310, and the screw 333 is threadedly connected to the rod body of the telescopic rod 1 310, and a knob 332 for driving the screw 333 to move up and down is fixedly installed at one end of the screw 333 away from the telescopic rod 1 310, and a fixing frame 331 for supporting the screw 333 is fixedly installed at the upper and lower ends of the telescopic rod 1 310, so that when the operator needs to remove the USB plug 101 from the USB plug 101, the locking assembly 330 includes a clamping plate 334 disposed in the cavity of the telescopic cavity 311 for clamping the rod body of the telescopic rod 2 320, and a screw 333 for driving the screw 333 to move up and down is fixedly installed at the upper and lower ends of the telescopic rod 1 310. The protective cover 200 is firstly driven by the knob 332 to drive the threaded connection between the screw rod 333 and the fixing frame 331 and the telescopic rod 1 310, so as to drive the clamping plate 334 to release the lock of the telescopic rod 2 320. At this time, the telescopic rod 2 320 can be extended and retracted left and right in the telescopic rod 1 310. At this time, the protective cover 200 can be removed from the USB plug 101, and then the telescopic rod 2 320 can be rotated to insert the protective cover 200 into the fixed plug 102. Finally, the telescopic rod 2 320 is locked by the locking assembly 330, so that the protective cover 200 is not easily lost or dropped during the carrying and use of the wireless network card body 100.
