Description

electronic card connector

【Technical field】

The utility model relates to an electronic card connector, in particular to an electronic card connector suitable for a notebook computer and capable of accommodating an electronic card.

【Background technique】

There are many specifications of electronic memory cards used in the industry at first, and various electronic memory cards of different specifications are used by different manufacturers on different devices. Since they are not compatible with each other, there is a big problem in data exchange. Therefore, in order to solve the above-mentioned data exchange problems, PCMCIA (Personal Computer Memory Card International Association) standardized the specifications of electronic memory cards in the industry. The standardized electronic memory cards were referred to as PC cards. PC cards were mostly Used on the server, mainly for permission control. Later, due to the rapid development of notebook computers, signal transmission devices were developed in a smaller, lighter and more portable direction. Therefore, PC cards began to be widely used as input/output interfaces of notebook computers. So far, the PC card developed by the Personal Computer Memory Card International Association has developed three different models to meet the different needs of the industry.

With the development of the times, the data transmission capacity of digital equipment has been greatly increased, and at the same time, it is necessary to maintain a relatively fast transmission rate, which makes the current PC card more and more unable to meet the requirements of current use in data transmission. Therefore, personal computers The Memory Card International Association is formulating standards for new PC cards to meet new requirements. Compared with existing PC cards, the main advantages of new PC cards are their fast data transmission rate and small size. The transfer speed of the new PC card can reach peak data transmission of 250 megabytes per second in one direction or 500 megabytes per second in both directions. This is about 4 times higher than the peak performance of existing 32-bit PC cards. Please refer to shown in Fig. 1, novel PC card will appear with two kinds of outward appearances, and the thickness of this first type novel PC card 50 is consistent with the thickness of second type novel PC card 60, and these two kinds of novel PC cards are used for transmitting data The configurations of the butt joints 51, 61 are consistent. The first type of new PC Card is only about half the size of current PC Cards. The second type of novel PC card is also very different from the configuration of the existing PC card for the L configuration.

Because the PC card must be used in the above-mentioned various devices through the electronic card connector matched with it, every improvement of the PC card technology must correspondingly require corresponding improvements in the electronic card connector matched with it. From the above, it can be seen that the configuration of the new PC card is very different from the existing PC card, so the existing electronic card connector for mating with the existing PC card cannot be mated with the new PC card. Therefore, the industry needs to develop two new types of electronic card connectors to be mated with two new types of PC cards respectively.

Further, since the two new types of PC cards are used in notebook computers, and notebook computers are developing in the direction of thinning and miniaturization, and their internal space is limited, how to use the electronic devices that are respectively used to match the two new types of PC cards? The integration of the card connector into one to improve the compatibility of a single electronic card connector and simultaneously improve the utilization of the internal space of the notebook computer has become the research and development focus of the industry.
