Problems solved by technology

[0003] Since the wireless performance of the data card is related to the DC ground of the connected device, if the size of the dedicated power adapter for the data card is small, the radiation performance of the antenna of the data card will drop rapidly, resulting in data The wireless performance of the card deteriorates seriously, especially in the 800MHz-1000MHz frequency range
[0004] Through the research on the prior art, the inventor found that: in order to meet the wireless performance of the whole machine in the 800MHz-1000MHz frequency band, the existing power adapter dedicated to the data card usually increases the size of the DC ground of the power adapter. The size requirement is very large. To meet the low-frequency wireless performance indicators, the size of the adapter needs to be very large. If the size of the adapter is large, there will be a problem of inconvenient portability, which is contrary to the portability of the data card itself.

Embodiment 1

[0024] A data card power adapter provided by an embodiment of the present application includes: a housing and a circuit board, wherein the circuit board is arranged in the housing.

[0025] As a protective device, the main function of the shell is to encapsulate the circuit board inside, avoid exposing the circuit board to the place where the user can touch it, and then prevent the user from touching the circuit board and causing electric shock accidents.

[0026] A power plug connected to a power source may be provided on the casing to facilitate power supply to the data card power adapter. Here, the power plug provided on the casing can be arranged inside the casing through a rotating shaft or a chute, so that when the power plug is not needed, the plug can be rotated or pushed inside the casing to hide it; , by turning the plug out or out of the housing. Such a design can reduce the volume occupied by the power plug when not in use.

[0027] In addition, in other embodime...

Embodiment 2

[0035] figure 1 It is a schematic diagram of a disassembled structure of a power adapter for a data card provided in the embodiment of the present application.

[0036] Such as figure 1 As shown, the data card power adapter includes: a housing (not shown in the figure) and a circuit board 1 arranged in the housing.

[0037] At least one plug-in interface connected with the data card is provided on the circuit board 1, so as to facilitate the user to insert the data card into the plug-in interface. In order to support a variety of different types of data cards and meet the different needs of users, in this embodiment of the application, the number of plug-in interfaces can be multiple, and the types of multiple plug-in interfaces can be the same or can be Not the same. In addition, in the embodiment of the present application, a commonly used USB interface may be selected as the plug-in interface.

Abstract

The application discloses a power adapter for a data card. The power adapter comprises an outer housing and a circuit board, wherein the circuit board is arranged in the outer housing, at least one plugging-unplugging interface connected with the data card is arranged on the circuit board, and openings communicated with the plugging-unplugging interfaces are arranged on the outer housing; and the power adapter further comprises a direct current ground extending part, wherein the direct current ground extending part is arranged in the outer housing, one end of the direct current ground extending part is connected with the plugging-unplugging interfaces of the circuit board, and the other end of the direct current ground extending part is in the status of an open circuit or is connected with the direct current ground of the power adapter. Compared with the prior art, the power adapter for the data card can effectively improve the radiance performance of the low-frequency stage of an antenna under the condition that the size of the whole adapter is not increased. Furthermore, the power adapter for the data card is less in volume, so that the carrying requirement when users travel can be met; and the power adapter for the data card can be conveniently used by the users.

Description

technical field [0001] The present application relates to the technical field of mobile terminal products, in particular to a data card power adapter. Background technique [0002] At present, data card products, such as: wireless network cards that can connect to wide area wireless networks, wireless network cards that can connect to wireless local area networks, and Bluetooth adapters, etc. These data cards are passive devices that allow users to easily connect to wireless networks, greatly It is convenient for users to use during travel. When the data card is in use, it usually needs to be powered by other devices to work normally. One kind of situation is to connect the data card to a portable device, such as a laptop, a tablet computer or a mobile phone, etc., and another kind of situation is to insert the data card into a In the dedicated power adapter, during use, the data card can use the DC ground in the portable device or the dedicated power adapter as the referen...
