Double Layer Connectors for Digital Video Interfaces

Abstract

The invention relates to a bilayer connector of a digital video interface. A seat is provided with a vertical portion and a horizontal portion, a first connector is integrally positioned on the vertical portion, a second connector is arranged above the first connector, an abutting portion capable of penetratingly positioning a plurality of second terminals is arranged in front of a base of the second connector, welding ends of the second terminals obliquely extend to form support arms towards the abutting portion, the support arms are secondarily bent by a preset angle, and the tail ends of the support arms are provided with contact portions which are perpendicular to the welding ends. Equivalent capacitance is improved by properly changing continuity of the secondarily bending preset angles of the second terminals and the distances among the terminals, and by the aid of adjusting shape changes of the terminals to match with characteristic impedance, high-frequency signal reflection is effectively reduced. Accordingly, integrity of signals is greatly improved, so that the integral signal transmission is more stable and reliable, and quality of high-speed transmission signals is improved.

Description

technical field [0001] The invention provides a double-layer connector for a digital video interface, especially a second connector positioned above the first connector on the seat body, and a plurality of second terminals positioned through the second connector. That is, the quality of the high-speed transmission signal can be enhanced by appropriately changing the predetermined angle of the secondary bending of the second terminal and the distance between the terminals, supplemented by adjusting the shape of the terminal to match the characteristic impedance. Background technique [0002] Now that the transmission technology has entered the digital age, users and manufacturers have higher and higher requirements for the quality of digital display. Combining with the digital display interface standard of display card hardware, its development progress has attracted more attention, so that high-speed transmission technology must also continue to improve. To meet the ever-cha...

Problems solved by technology

[0006] The main purpose of the present invention is to overcome the problem that the existing double-layer DVI connector architecture does not consider the transmission characteristics of high-frequency signals (such as electromagnetic interference, impedance matching, etc.), and effectively reduce the characteristic impedance generated by the signal under high-speed transmission. Reduce the reflection of high-frequency signals, thus greatly improving the integrity of the signal, making the overall signal transmission more stable and reliable, and enhancing the quality of high-speed transmission signals
