Description

Mini PCI-E digital card wireless module with card reading function

technical field

The invention relates to a PCI-E digital card wireless module, in particular to a Mini PCI-E digital card wireless module with card reading function.

Background technique

In the past, the peripheral component interface PCI (Peripheral Component Interface) in personal computers was used to provide a transmission interface specification for connecting various functional devices, such as: VGA display adapter (Video Graphics Array; VGA), sound card, network card, data card, image capture card, TV card, SCSI (Small Computer System Interface) card, and 1394 (computer interface IEEE1394, commonly known as FireWire interface) expansion card, etc. Wherein, because PCI (Peripheral Component Interface) peripheral devices need to share the total bandwidth of the PCI, so when there are more PCI peripheral devices connected, the bandwidth available for each device will be less, so that the transmission of each device Speed is limited. Today, the processing speed of personal computers and the amount of data to be transmitted by various peripheral devices have been greatly increased, and faster bandwidth is required to carry the transmission. Therefore, the bandwidth that PCI can carry began to be insufficient, and became a bottleneck in the internal data transmission of the computer. For this reason, Intel Corporation has begun to lead the development of a new generation of PCI-Express (a new generation of bus interface) transmission interface specification, which can provide faster bandwidth for more efficient data transmission between peripheral devices. For example: the calculation and processing of 3D images in games requires not only a fast central processing unit, but also a fast bandwidth to transmit the calculation results to the display adapter; others such as GigaByte Ethernet (GigaByte Ethernet), ultra-wideband (Ultra Wideband; UWB for short) wireless network, high definition content-related hardware, and disk array control card (RAID Controller), etc., all require high bandwidth and constant connection efficiency at any time. Only the PCI-Express transmission interface specification can meet the requirements. At present, in general personal computers, in response to the consideration of the production cost of the mainboard and the internal space of the personal computer, most of the mainboards only have one or two PCI-Express slots, so the PCI-Express slots that users can connect and use The number of peripheral devices related to the interface is also limited, which becomes a fly in the ointment.

Contents of the invention

The purpose of the present invention is to provide a Mini PCI-E digital card wireless module with a card reading function to achieve the effect of expanding the interface.

To achieve the above object, the present invention employs the following technical solutions:

A Mini PCI-E digital card wireless module with card reading function, comprising a circuit board, a Mini PCI-E port and a card reading device, wherein one end of the circuit board has a contact unit; the Mini PCI-E port is located on the The circuit board; the card reading device is arranged on the circuit board.

The contact unit of the circuit board is a golden finger, so it can be inserted into a slot conforming to the standard of PCI-Express.

The circuit board also has a fixing hole, so that when the present invention is applied in a computer system, it can be fixed in the computer system by using the fixing hole except that it can be inserted into a slot conforming to the PCI-Express standard. , so as to achieve the effect of double fixation.

The card reading device of the present invention can be used to read a memory card or a SIM card, so that the wireless module is not only capable of data transmission, but also can achieve the effect of expanding the interface.

After adopting the above structure, the Mini PCI-E digital card wireless module with card reading function of the present invention can be inserted into the slot in the computer system that conforms to the PCI-Express standard through the contact unit on the circuit board. The PCI-E port and a card reading device achieve the effect of expanding the interface and perform high-speed data transmission.

Detailed ways

In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

Please refer to FIG. 1 and FIG. 2 , which are block schematic diagrams and plan schematic diagrams of the present invention. As shown in the figure, the Mini PCI-E digital card wireless module 10 of the present invention includes a circuit board 20, a Mini PCI-E port 30 and a card reading device 40. in:

One end of the circuit board 20 is provided with a contact unit 21. In a preferred embodiment of the present invention, the contact unit 21 is a gold finger commonly known as a gold finger; and the circuit board 21 is additionally provided with a fixing hole 22. In this embodiment, the fixing hole 22 is disposed on the other end of the circuit board 20 opposite to the contact unit 21 .

The Mini PCI-E port 30 is located on the circuit board 20. In this embodiment, the Mini PCI-E port 30 is located on the circuit board 20 behind the contact unit 21, and is electrically connected to the contact unit 21.

The card reading device 40 is arranged on the circuit board 20 and electrically connected with the Mini PCI-E port 30. It is worth mentioning that the card reading device 40 is used to read a memory card or a SIM card.

Through the contact unit 21 on the circuit board 20, the Mini PCI-E digital card wireless module 10 of the present invention can be inserted into a slot conforming to the PCI-Express standard (which is the prior art, not shown in the drawings) , and the fixing hole 22 on the circuit board 20 can be used to fix the circuit board 20 in a computer system (not shown in the drawings), so that the Mini PCI-E digital card wireless module 10 can be more firmly fixed on the In the computer system, and high-speed data transmission.

Moreover, the card reading device 40 on the circuit board 20 can also be inserted into a memory card or a SIM card, thereby achieving the effect of an expansion module.

It is worth mentioning that when the Mini PCI-E digital card wireless module 10 of the present invention is inserted into the computer system, the user can directly insert and remove the memory card or the SIM card on the Mini PCI-E digital card wireless module 10 Or replace it to achieve the effect of expanding the interface. Moreover, different memory cards or SIM cards can be replaced with different habits of users.
