Embodiment Construction

[0045] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as figure 1 and figure 2 As shown, the electrical connector 100 of the present invention is used for mating with a mating connector (not shown), and the electrical connector 100 is mounted on a circuit board (not shown). In this embodiment, the electrical connector 100 is a connector for transmitting high-frequency signals, that is, an HDMI2.1 connector. Of course, in other embodiments, the electrical connector 100 may also be other connectors for transmitting high-frequency signals.

[0047] For the convenience of description, the direction in which the electrical connector 100 is mated with the docking connector is the front-rear direction, and the electrical connector 100 is docked with the docking connector f...

Abstract

The invention discloses an electrical connector, comprising an insulating body, a plurality of first terminals are accommodated in the insulating body and include a first differential pair and a second differential pair, one side of the first differential pair is not provided with a grounding terminal, and the second There are ground terminals on both sides of the differential pair, the distance between the first differential pair and the adjacent ground terminal is smaller than the distance between the second differential pair and the adjacent ground terminal, or the first differential pair is exposed outside the insulating body The width of the part is greater than the width of the part of the second differential pair exposed outside the insulating body, or the distance between the terminals of the first differential pair is smaller than the distance between the terminals of the second differential pair to adjust the first differential pair The impedance of the first differential pair is compensated for the lack of a ground terminal on one side of the first differential pair, resulting in a larger impedance, so that the impedance of the first differential pair is the same as the impedance of the second differential pair to achieve impedance matching, and the structure of the entire connector is simple. The processing and assembling method is simple and the cost is saved.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector for transmitting high-frequency signals. 【Background technique】 [0002] HDMI is the abbreviation of (High Definition Multimedia Interface), which means high-definition multimedia interface. It is a digital video / audio interface technology. It is a special digital interface suitable for image transmission. 48Gbps (version 2.1). Among them, the HDMI connector before HDMI2.1 only opened the signal transmission channels of 3 differential signal pairs, and the maximum transmission speed was 36Gbps, while HDMI 2.1 opened the signal transmission channels of 4 differential signal pairs, and the maximum transmission speed can reach However, since one side of the newly opened differential signal pair does not have a ground terminal, while the other three differential signal pairs have ground terminals on both sides, resulting in an impedance mismatch that does not meet...
