[0036] Such as Figures 1-5A USB wireless network card shown in the figure includes a housing 100, a frame 200, a PCB board 300, and a USB iron head 400; one end of the housing 100 has an opening 101, and a card slot 102 is provided on the inner side wall of the housing 100, and the card slot 102 is arranged close to the opening 101; one end of the frame 200 is provided with an elastic buckle 204, one end of the frame 200 extends into the housing 100 from the opening 101, and the elastic buckle 204 extends into the card slot 102; the PCB board 300 is arranged on the frame 200, and the PCB board 300 extends into the housing 100; the USB iron head 400 is snap-connected to the frame 200, and the USB iron head 400 is sleeved on the other end of the frame 200. It should be noted that the number of the elastic buckle 204 and the card slot 102 is two each. The two card slots 102 are respectively arranged on the opposite sides of the inner wall of the housing 100, and the two elastic buckles 204 are respectively arranged on the opposite sides of the end face of the frame 200. When assembling the network card, only need to put the PCB board 300 into the frame 200, then extend one end of the frame 200 into the housing 100, so that the elastic buckle 204 extends into the card slot 102 to realize the snap connection between the frame 200 and the housing 100, and finally install the USB iron head 400. Moreover, the USB iron head 400 and the frame 200 are also snap-connected, which is very convenient. When assembling the network card, no auxiliary tool is needed, greatly improving the assembly efficiency of the network card.

[0037] Please refer to Figure 4 , in a possible implementation manner, the frame 200 includes a plug head portion 201, a connecting portion 202, and a limiting portion 203; the plug head portion 201 extends into the housing 100, the elastic buckle 204 is arranged at one end of the plug head portion 201, and a through hole for the PCB board 300 to pass through is provided in the middle of the plug head portion 201; the connecting portion 202 is arranged at the other end of the plug head portion 201, the connecting portion 202 extends into the USB iron head 400, and the connecting portion 202 is snap-connected to the USB iron head 400; the limiting portion 203 is arranged at the other end of the plug head portion 201, the limiting portion 203 extends into the USB iron head 400, and the PCB board 300 is placed on the limiting portion 203. It is easy to understand that the plug head portion 201, as the main body of the frame 200, is mainly used to connect with the housing 100 and partially block the opening 101 of the housing 100. The connecting portion 202 is mainly used to connect with the USB iron head 400. The limiting portion 203 is located below the connecting portion 202. The limiting portion 203 is mainly used to provide an installation basis for the PCB board 300 and play a limiting role on the PCB board 300.

[0038] Please refer to Figure 2 and Figure 3, in a possible implementation, the opening 101 is in a flared shape, and the outer wall of the plug head 201 fits snugly against the inner wall of the opening 101. It is easy to understand that the inner wall of the housing 100 near the opening 101 is inclined, that is to say, the diameter of the opening 101 is larger closer to the USB iron head 400. Correspondingly, the outer wall surface of the plug head 201 is also inclined. This design enables the plug head 201 to more easily extend into the housing 100, which is beneficial to improving the assembly efficiency of the network card. More specifically, the inclination angles of the four sides of the plug head 201 can be freely designed according to actual needs. In this embodiment, the inclination angles of the left and right sides of the plug head 201 are greater than the inclination angles of the upper and lower sides, so that the elastic buckle 204 provided on the side of the plug head 201 has better performance.

[0039] Please refer to Figure 4 , in a possible implementation, the longitudinal cross-section of the limiting portion 203 is L-shaped, so that the end face of the PCB board 300 also abuts against the limiting portion 203. It should be noted that the middle of the limiting portion 203 is a hollow structure to reduce the material used for the limiting portion 203, and the end of the limiting portion 203 has a protrusion extending upward, so that the longitudinal cross-section of the limiting portion 203 is L-shaped. After the PCB board 300 is placed on the limiting portion 203, the end face of the PCB board 300 abuts against the protrusion at the end of the limiting portion 203 to limit the PCB board 300 and prevent the PCB board 300 from shifting, which is beneficial to improving the stability of the PCB board 300.

[0040] Please refer to Figure 2 , in a possible implementation, a positioning portion 103 is provided on the inner wall of the housing 100, and the end face of the plug head 201 abuts against the positioning portion 103. It is easy to understand that the positioning portion 103 is in a stepped shape. When the frame 200 is connected to the housing 100, the plug head 201 extends into the housing 100 from the opening 101. When the plug head 201 extends to a predetermined position, the end face of the plug head 201 abuts against the positioning portion 103, thereby positioning the frame 200.

[0041] Please refer to Figure 5 , in a possible implementation, a clamping portion 401 is provided on the inner wall of the USB iron head 400, and a clamping hole 205 is provided on the connecting portion 202, and the clamping portion 401 extends into the clamping hole 205. It is easy to understand that by providing the clamping portion 401 on the USB iron head 400 and providing the clamping hole 205 that cooperates with the clamping portion 401 on the connecting portion 202, the snap connection between the USB iron head 400 and the frame 200 is realized, which provides convenience for the installation of the USB iron head 400.

[0042] Please refer to Figure 5, in a possible implementation, the clamping portion 401 has a first guiding inclined surface 402. It is easy to understand that the clamping portion 401 has a certain elasticity. The first guiding inclined surface 402 is located at one end of the clamping portion 401 close to the housing 100. The setting of the first guiding inclined surface 402 enables the clamping portion 401 to enter the clamping hole 205 more smoothly.

[0043] Please refer to Figure 4 , in a possible implementation, the elastic buckle 204 has a second guiding inclined surface 206. It is easy to understand that the setting of the second guiding inclined surface 206 can guide the elastic deformation of the elastic buckle 204, so that the elastic buckle 204 enters the clamping groove 102 more smoothly, which is beneficial to improving the installation efficiency of the frame 200.

[0044] Please refer to Figure 3 , in a possible implementation, a limiting protrusion 403 is provided on the inner side wall of the USB iron head 400, and the limiting protrusion 403 contacts the PCB board 300. It is easy to understand that the PCB board 300 is prone to shaking in the up and down direction, and the setting of the limiting protrusion 403 can cooperate with the limiting portion 203 to clamp the PCB board 300, thereby playing a fixing role on the PCB board 300 to improve the stability of the PCB board 300. Moreover, the side wall surface of the limiting protrusion 403 is an arc surface to prevent the limiting protrusion 403 from damaging the PCB board 300 when pressing the PCB board 300.

[0045] The above embodiments are only the preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
