Card connector. [Prior Art] In the computer or telecommunication circuit, the interface connected with the outside world is often designed as a bus bar to transmit various materials, and the hardware is in the form of an expansion slot, which is called a card. The connector is attached to the motherboard to connect the modular card such as the interface card and the memory to actually realize the function of the connection interface. The card connector for connecting the motherboard and the daughter card is usually connected by using a through hole for connecting the connector on the motherboard, plating the conductive metal around the inside of the through hole and the through hole, and the mother board The circuit to be connected to the bus bar is connected to the corresponding through hole; the pin of the card connector is passed through the through hole of the motherboard and temporarily held on the motherboard, and then secured by a soldering process or other connection method. The ground is held on the motherboard and electrically connected to the motherboard. The daughter card contains various electronic components and circuit structures required to achieve the interface function, and is formed into a "golden finger" shape at one end of the disk card connector connection, that is, a rectangular or elliptical conductive pad connected to the daughter card. The route. The daughter card has:: the side into which the card connector is inserted into the slot of the card connector. The connector end of the connector is the contact area of the body. The other end of the conductor is the connector soldered to the motherboard: gold The fingers are in contact with the conductor contact areas of the connector one by one, thus allowing the motherboard to communicate with the daughter card. The main function of the electrical connector is the complete and correct transmission of the signal, which is a typical passive component. In recent years, due to the increasing speed of computer central processing units (CPUs), from the early 33MHz, 66MHz, to the Pentium m 500MHz to the recent Pentium iv 3 〇 6GHz, the electronic signal transmission speed between the motherboard and the computer is required to be increased. Give it the speed it deserves. The transmission mode of the signal through the connector can be divided into two types: one is a single-ended signal (single-ended signal), and the other is a differential mode signal. A so-called single-ended signal uses only one conductor for transmitting an h-number between two connected electronic components or devices. Differential signaling | Tiger transmission requires two identical and identical conductors to transmit signals back and forth between the two connected electronic components or devices. The differential signals transmitted on the two conductors are two complementary signals, i.e., the amplitudes are the same and the polarities are opposite (the phase difference is 180 degrees). In the high-frequency transmission environment, the differential signal transmission can obtain better electrical performance, and it is easy to achieve the timing and response capability required by the system, reducing the chance of the system misjudged or losing part of the data. Therefore, when the card connector is actually applied to connect various interface cards, memory modules, etc. to the motherboard, the majority of the conductors (generally referred to as "terminals") located on one side of the connector are used to transmit signals. Although the differential signal transmission has better electrical characteristics than the single-ended signal, the electrical characteristics of the differential signals of the opposite polarity are still affected by the connection design, for example, the conductor of the conductor, etc. #,n The θ- shape is configured by this time = the volume of the inoculated computer and communication equipment is reduced, and the distance between the shrinkage and the conductor must be more and more fine. 'The distance between the conductor and the conductor of the connector is reduced, and the density of the pin is increased. Frequently caused problems, / string day (four) ((10) ss seams. If a good connector design H3554.doc 200812159 difficult but need to face the course to get the system's desired performance' is a problem today.
