Abstract

The utility model relates to a wireless WAN card which comprises a body, a circuit board and a universal serial bus (USB) plug. The circuit board is fixed in the body. The circuit board comprises a main circuit board, a USB circuit board and a flexible circuit board which connects the main circuit board and the USB circuit board. An accommodating cavity is formed in the body, and a sliding rail is arranged on a side wall of the accommodating cavity. One end of the sliding rail fixes the main circuit board and the other end of the sliding rail is close to an outlet of the USB plug. The USB plug and the USB circuit board are fixed on a sliding block and can slide on the sliding rail through the sliding block, and therefore the purpose of stretching out of the outlet and retracting into the outlet of the USB plug is achieved. The USB plug of the wireless network card can be stretched out of the body when in use and be retracted into the body when not in use, and therefore the purpose of protecting the USB plug can be achieved. The wireless WAN card is convenient to use, and greatly shortens the integral length when not in use.

Embodiment

In order better the utility model patented technology scheme to be understood, be elaborated through instantiation and conjunction with figs. below.

Please refer to Fig. 1 to Fig. 4; Among one embodiment; Wireless Internet card mainly comprises card of surfing Internet body 8, be installed in sliding rail rack 5 in the body 8, be fixed in sliding rail rack 5 one ends main circuit board 12, be positioned on the sliding rail rack 5 can before and after slide slide block 4, the USB plug 1 that is fixedly connected through USB wiring board 11 with slide block 4, be connected with slide block 4 and stretch out sliding button 3 outside the body 8 and the FPC 6 that an end is connected with main circuit board 12, the other end is connected with USB wiring board 11.

Body 8 comprises loam cake and lower cover, is formed for accommodating the host cavity of sliding rail rack 5, each wiring board, slide block 4 and USB plug 1 between the upper and lower cover, and this host cavity communicates with the outlet of USB plug 1.

Sliding rail rack 5 is fixed on down and covers, and is formed with a groove 51 on it, is formed with parallel chute 52 as slide rail on two relative sidewalls of this groove 51.Main circuit board 12 is fixed on an end of slide rail, and the other end of slide rail is near the outlet of USB plug 1.Among other embodiment, sliding rail rack 5 can be one-body molded with body 8.

The bottom of slide block 4 just is housed in the groove 51, and the bottom of slide block is formed with the convex edge that can insert chute 52, relies on this convex edge and chute 52, and slide block 4 can successively move on sliding rail rack 5 along chute 52.Be formed with on the slide block 4 towards the holding section 41 of USB wiring board 11 protrusions, it is barb-shaped that holding section 41 is substantially.Be formed with the through hole 12 corresponding on the USB wiring board 11 with holding section 41.The end of holding section 41 passes through hole 12 and catches on the edge of through hole 12, thereby is fixed on the USB wiring board 11.

Sliding button 3 is from slide block 4 protrusions, and the direction of protrusion is basically perpendicular to the glide direction of slide block 4.Have the groove 81 that supplies sliding button 3 to stretch out on the body 8 on the position of corresponding sliding button 3.The terminal upper process that stretches out groove 81 of sliding button 3 has many projections, makes things convenient for the user with manual manipulation sliding button 3.In the present embodiment, slide block 4 is provided with articulated section 42, and an end of sliding button 3 is installed in the articulated section 42 and achieves a fixed connection.

The both sides towards the end of USB wiring board 11 of USB plug 1 are provided with buckle 13 (seeing also Fig. 5).USB wiring board 11 is provided with the groove corresponding with this buckle 13, and USB wiring board 11 achieves a fixed connection through buckle 13 and cooperating of groove with USB plug 1.The thickness of USB plug 1 is 2.4mm.

USB wiring board 11 and main circuit board 12 and laterally arrange down not in same plane haply.Side near FPC 6 of USB wiring board 11 is formed with a projection (for indicating).FPC 6 extends to the another side (about double flat) of projection from the one side of projection, and is fixed on the another side of projection.So, when USB wiring board 11 slides with slide block 4,, can the many places bending not cause USB plug 1 to be stuck always FPC 6 only has a place to bend about 180 degree.

During use, promote slide block button 3, slide block button 3 drives slide block 4 front and back on sliding support 5 and slides.Simultaneously, slide block 4 also drives USB wiring board 11 front and back slip above sliding support 5.Certainly, thus USB plug 1 slides before and after also and then above sliding support 5 to be realized stretching out and purpose that the USB plug of withdraw exports.

In this process; FPC 6 is converted into two-layer, and lower floor's one end is fixed on the main circuit board 12, and upper strata one end is fixed on the USB wiring board 11; Mid portion follows USB wiring board 11 to move; Slide block button 3 is controlled slide block in the side of card of surfing Internet, thereby the control USB plug stretches out outside the card of surfing Internet in use, and the retraction card of surfing Internet is inner when not using.

In sum, the advantage of the utility model is:

(1) easy to use, no longer need the USB cap to protect USB plug, USB plug can the indentation machine intimate under obsolete situation, provides cost savings the puzzlement of having avoided user loss USB cap to cause;

(2) USB plug has shortened the whole length of card of surfing Internet because can the indentation machine intimate;

(3) the USB plug thickness of innovative design is about half of generic USB plug thickness (its thickness is merely 2.4mm), has controlled the thickness of card of surfing Internet complete machine effectively.

The foregoing description is just listed the principle and the effect of expressivity explanation the utility model, but not is used to limit the utility model.Any personnel that are familiar with this technology all can make amendment to the foregoing description under the spirit and scope of the utility model.Therefore, the rights protection scope of the utility model should be listed like claims.
