New description: [New technical field] This is a kind of electrical connector, especially an electrical connector with a structure that simultaneously reduces crosstalk and impedance mismatch, and thus has a good high-speed transmission interface. [Prior Art] Universal Serial Bus (USB) Lu is a serial bus system standard for connecting computer systems and external devices. It is also a technical specification for input and output interfaces. It is widely used in display cards. Devices such as notebook computers and consumer electronics; currently available on the market is USB 2.0' and the latest specification is USB 3.0. USB3.0 has two pairs of differential signal transmission terminals than USB2.0, among which SSTX + and SSTX- are pairs of differential jg output terminals 'SSRX + and SSRX- are differential signals · receiving terminals, and these two pairs of terminals are added. USB3.0 can support full duplex, so USB3.0 transmits signals faster than USB2. However, in the case of high-frequency transmission, multiple terminals in the electrical connector are prone to crosstalk and high frequency. The problem of impedance mismatch during transmission will become obvious. Therefore, the current domestic patent No. M363140 "Electrical Connector" discloses a type A socket connector, mainly consisting of a body 71 and a plurality of first terminals. 72', a plurality of second terminals 73 and a shielding shell 74, the appearance of which is shown in FIG. 8, which discloses the appearance of the second and the shielding terminals 74 of the first terminal 72 and the second terminal 73 in the electrical connector. The first terminal 72 and the second terminal ^ are vertically folded downward; for the terminal arrangement and the external pin definition, please refer to FIG. 8 and FIG. 9, and the middle four terminals are the first terminal 3 arranged under the body 71. M400707 72' three terminals on the left and right sides are arranged on the upper layer of the body 71 The two terminals 73 〇 are separated from the twisted pair transmission terminal 72a by using two ground terminals 73b, 72b or a power terminal 72c and a ground terminal 73b to reduce the problem of a few crosstalks, but the figure 8 and FIG. 9 , the first and second terminals are respectively located in the upper and lower layers and the second terminal 73 is located on the same plane as the end of the pin and the flat end of the first terminal 72. The length of the vertical fold is larger than the length of the first terminal 72 that is vertically folded down. The difference between the lengths of the second terminal 73 and the first terminal 72 is such that the impedance is easily mismatched. All of the above are known as the electrical connector knot = the ideal of the dish, and it is necessary to proceed with the review and seek a feasible solution. [New content] In view of the shortcomings of the above-mentioned existing electrical connectors, M ^ +1 t is intended to reduce the crosstalk problem and the resistor at the same time. The electrical connection of the matching phenomenon is the main technical sentence adopted to achieve the foregoing purpose. The electrical connection state includes a terminal block, a plurality of first terminals, and a plurality of second terminals. The terminal block is formed with a plurality of openings divided into upper and lower layers; each of the first terminals has a first end and -/ respectively a lower opening through the terminal block, and the fourth 'the first end thereof is a pin; Each of the first and second ends is formed with a first end having an upper opening through the terminal block, and the first: the second end, the first leg thereof; and the end of the end are respectively formed with a second trick. Each of the first ends having the γ-axis and the Z-axis has more than one second pin on the YZ plane, and the three-dimensional right-angle coordinate system is obliquely bent. The second leg-shaped shape of the creation is an oblique test. The shape of the pin of the second terminal part of the electrical connection is vertical and folded. According to the Pearson's theorem, the length of the oblique bending is smaller than the total length of the vertical watering test, so the creation can be effectively shortened. The first pin is / the length of the pin The gap can be reduced

Separated, and the twisted pair transmission terminals 21b are separated by a ground terminal 3, which can effectively reduce crosstalk; the ground terminal 21a and the power terminal 21. U and p terminals (i.e., the first and fourth first terminals 21 from left to right) are provided in the illustrated direction from left to right, except for the isolation signal terminals (10), 31 a, 31. In addition to the function of c, there is another reason that the bending angle of the sub-transporting portion 212 is larger than the transmission portions M400707 212, 312 of the third and seventh sub-terminals 21, 31 at the other ends, so that the third and seventh terminals are made. Since the impedance change is larger than that of the other transmission portions 212 and 312, the ground terminal 23 and the power supply terminal 24, which have no impedance matching considerations, are defined at the third and seventh branch terminals having a large bending angle. The external pin definition of another preferred embodiment is as shown in FIG. 7. The other preferred embodiment has ten terminals, and the external pin definitions are from left to right: USB 3.0 GND, SSRX+, SSRX-, USB 2.0 GND, D+, D-, Vcc, SSTX-, SSTX+ and USB 3.0 GND. The difference between the pin structure of the preferred embodiment of the present invention and the structure of the existing electrical connector terminal is as shown in FIG. 1 , and the shape of the pin portion of the second terminal 73 of the electrical connector is vertically bent. The shape of the second transmission portion 31 2 of the preferred embodiment is obliquely bent. It can be known from the Pearson's theorem that the length of the oblique bending is smaller than the total of the vertical plus horizontal bending length, so the creation can effectively shorten the first The difference in length between the pin 21 and the second pin 31 can reduce the problem of impedance mismatch, and the design of the oblique bending can reduce the length of the pin, so that the signal passing through the pin will be on the other pin. The path of the signals interferes with each other is shortened, and the degree of mutual interference between the signals of the different pins is reduced, and the continuity of the curvature of the pins is more vertically bent than that of the existing electrical connector pins, thereby reducing the curvature of the pins. The effect of continuously causing electromagnetic wave scattering, together with the position and angle of the terminal, defines the external pin position, which can simultaneously reduce the crosstalk problem and the resistance mismatch phenomenon, thereby forming an electrical connector with a good high-speed transmission interface.
