Description

A data card with a USB interface

technical field

The utility model relates to a data card, in particular to a data card with a USB interface.

Background technique

Now there is a data card with a USB (Universal Serial Bus) interface on the market for wireless Internet access. There are two types of antennas for this type of data card: built-in and external. In order to improve radio frequency performance and reduce overall At present, the antennas of most data cards with USB interfaces are external, but the function of the external antenna is very single, and due to the influence of the size of the whole machine and the layout of the motherboard, the available space for the external antenna is very small .

Utility model content

The utility model provides a data card with a USB interface, the protective cover of the USB interface can slide, and serves as an external antenna of the data card.

In order to achieve the above object, the utility model adopts the following technical solutions:

A data card with a USB interface, comprising a USB interface, a casing, and a motherboard assembly arranged in the casing, and also including a slidable antenna, the slidable antenna includes an antenna housing and an antenna reed, and the antenna housing passes through the antenna reed The slidable antenna can be longitudinally slid to the head of the data card along both sides of the housing to be used as a protective cover for the USB interface to protect the USB interface.

Further, the utility model also includes a folding part, one end of the folding part is connected to one end of the housing through a rotating shaft, the USB interface is fixed on the other end of the folding part, and is connected to the Electrically connect the motherboard components described above.

The folding part can take the rotation axis as an axis, and realize staying at any angle between minus 90 degrees and plus 90 degrees.

The housing is provided with an antenna limiting mechanism for limiting the sliding range of the slidable antenna when sliding longitudinally along both sides of the housing.

The shell includes an upper shell and a lower shell, and the upper shell and the lower shell are connected together by screws, buckles or welding processes.

The copper sheet is fixed on the shell by hot stamping or super-welding process.

In the USB data card of the utility model, the slidable antenna can act as the USB interface protection cover of the data card at the same time, thereby making full use of the area of the slidable antenna, so that the user can slide the antenna back to the front end of the data card when the data card is not in use Act as a protective cover for the USB interface to protect the USB interface from external damage, and at the same time, there is no need to worry about the USB interface protective cover slipping off. The occurrence of problems such as loss.

Detailed ways

The utility model discloses a data card with a USB interface with a slidable antenna. The slidable antenna can serve as the USB interface protection cover of the data card at the same time, so that the user can slide the antenna when the data card is not in use. The front end of the data card acts as a USB interface protective cover to protect the USB interface from external damage, and at the same time, there is no need to worry about the USB interface protective cover slipping off.

Please refer to Fig. 1, this figure is the structure diagram of the data card with USB interface of the present invention, its structure mainly comprises upper housing 1, lower housing 2, slidable antenna 4, USB interface 6 and folding part 7, data card The motherboard assembly is located between the upper case 1 and the lower case 2 .

The slidable antenna 4 includes an antenna housing 41 and an antenna reed 42. The antenna housing 41 contacts the copper sheet 12 fixed on the upper housing 1 through the antenna reed 42 to realize signal connection. The hot or super welding process is fixed on the shell.

The slidable antenna 4 can slide longitudinally along the junction of the upper case 1 and the lower case 2, and when the slidable antenna 4 slides to the head position of the data card, it can serve as a protective cover for the USB interface 6 for Protect the USB interface 6, as shown in Figure 2, so that the data card of the present utility model does not need to be equipped with a special USB interface protection cover, which is convenient for users to use.

The upper shell 1 and the lower shell 2 are connected together by screws, buckles or welding processes. Both ends of the connection between the upper casing 1 and the lower casing 2 are provided with antenna limiting mechanisms for limiting the sliding range of the slidable antenna 4 when sliding longitudinally.

The USB interface 6 is fixed on one end of the folding part 7, and is electrically connected to the motherboard assembly through a USB connection line, and the other end of the folding part 7 is connected to one end of the upper casing 1 and the lower casing 2 through the rotating shaft 5 Connection, as shown in Fig. 3 and Fig. 4, the folding part can be rotated with the axis of rotation 5 as the axis, and it can stay at any angle between minus 90 degrees and plus 90 degrees.

Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and equivalent technologies thereof, the utility model is also intended to include these modifications and variations.
