Description

Card structure of high-speed transmission card

technical field

The utility model relates to a card insertion structure of a high-speed transmission card, which belongs to the field of electronic information technology products, and specifically belongs to the technical field of a card connection structure using a card for data transmission in electronic information products.

Background technique

Nowadays, with the vigorous development of electronic technology, the application of desktop computers or notebook computers can be said to be very extensive and popular. At the beginning, computer technology has advanced by leaps and bounds, and the operation speed of its central processing unit has been greatly increased, so that computer interface equipment transmission The speed must also be accelerated and upgraded. When the Peripheral Component Interconnect (PCI) commonly used in early computers transmits data with other interface devices, they can only share the bandwidth by relying on a common bus. When data is transmitted, the transmission is arranged in sequence. If the transmission data is large, the processing speed of the computer system will become slow, and the transmission speed and performance of peripheral components will be reduced.

Therefore, some people in the industry have developed a peripheral component high-speed connection interface (Peripheral Component Interconnect Express, referred to as the PCI Express connection interface), and its PCI Express connection interface has switching transmission technology and point-to-point transmission technology. With its independent transmission channel, it is no longer necessary to use the old shared bus architecture. In this way, it can effectively solve the problem of slow transmission speed caused by sharing a bus when the interface device transmits data. Nowadays, high-speed transmission cards are used (Express Card, referred to as Express card) connects the interface device to the PCI Express connection interface set on the computer, and through the USB 2.0 transmission channel, its data transmission speed far exceeds the existing PCI bus specification.

In addition, the currently used Express cards can only be inserted into the card connector of the PCIExpress connection interface alone, and various slots or connecting devices that can be inserted into the electronic cards are added on the card connector to make the electronic card The stored data can be electrically connected to the motherboard in the electronic product through the card connector, but other electronic cards cannot be directly integrated on the Express card.

With the rapid development of information technology, personal communication devices such as mobile phones and personal digital assistants have also been widely valued and applied. When using mobile phones, they need to use Subscriber Identity Module Card (Subscriber Identity Module Card, SIM card for short). ) to identify the user’s identity, and use the card connector of the SIM card to communicate and process information with the motherboard in the electronic product. Because the functions of electronic products are becoming more and more powerful, on the other hand, they tend to be lighter and thinner. , short, and small development, so how to effectively reduce the size has become one of the most basic design elements. However, the SIM card connector on the motherboard of the current electronic product can no longer meet the increasing number of interface devices. At this time, if the The addition of a SIM card connector on the motherboard will occupy a certain amount of space, which not only makes it difficult to arrange the predetermined electronic components on the motherboard, but also makes the overall design too complicated, the volume cannot be reduced, and the manufacturing cost is also increased a lot. , the miniaturization of the motherboard will also promote the motherboard and peripheral related electronic components to be set in the interface device. Therefore, if the existing Express card can be integrated with a slot or connection for the SIM card The device will become very meaningful, which can effectively reduce the space, quantity and cost occupied by the SIM card connector on the motherboard of the electronic product, thereby increasing its scope of applicability and improving the overall function and effect of use. The industry is eager to study the direction of improvement.
