High speed connector structure

The present invention relates to a high-speed connector structure, in particular, a gap is formed between a contact area of a signal terminal group and a bottom surface of a recess of an insulating seat, so that the contact area can increase the contact area with air to improve electrical performance and achieve improved transmission. The purpose of the rate; at the same time, through the negative terminal of the signal terminal group, a conductive plastic block is connected, and the shielding property of the conductive plastic block can reduce mutual interference between adjacent signals, so that the connector can transmit a faster rate.

With the advent of the technological age, a large number of electronic and electrical products are filled with the living environment and working environment, and also provide many conveniences in life and work. Therefore, various electronic and electrical products need to be transmitted through a connector for data or power signals during use and operation.

However, the connector with high-speed data transmission greatly improves the performance and brings convenience to life, but it also brings unprecedented challenges to the design and testing of signal integrity and compatibility, mainly because of the high speed. In terms of compatibility, the connector must increase the volume or path length of its terminal, so that the high-speed connector can be more matched to the standard impedance of the system by 100 ohms to achieve the purpose of increasing the transmission rate; however, increase the size of the terminal of the high-speed connector. Or the length of the path not only increases the cost, but also causes the volume of the high-speed connector to become larger. Another reason is that the high-speed connectors of the conventional high-speed connectors are interfered by the signals between the terminals, so that the data transmission speed of the high-speed connectors cannot be improved.

In view of the above problems, the main purpose of the present invention is to provide a high speed connector structure including an insulating base, a plurality of terminals and at least two conductive plastic blocks. The insulating base body is provided with at least one groove on the tongue plate thereof; the plurality of terminals comprise first and second signal terminal groups and power supply terminal groups disposed on the tongue plate, respectively comprising terminals having positive and negative terminals, and each terminal Each has a contact area, wherein the contact area of the terminal of the first signal terminal group is respectively disposed in the groove, and is formed with a gap from the bottom surface of the groove; the conductive plastic block is respectively connected with the contact area of the negative terminal of the first and second signal terminal groups; . Thereby, the first signal terminal group is formed with a gap between the contact area and the bottom surface of the groove, so that the contact area can increase the contact area with the air to improve the electrical performance, thereby achieving the purpose of increasing the transmission rate; and simultaneously shielding the conductive plastic block. The hood feature reduces mutual interference between adjacent signals, allowing the connector to transmit at a faster rate.
