The present invention relates to the technical field of connectors, and more particularly to a high-speed signal terminal, a differential signal terminal pair and a high-speed connector assembly, which can be used in a high-density, high-speed transmission environment and have good high-speed signal transmission performance.
In recent years, the requirement for extremely large bandwidth in high-speed communications is increasing significantly. Bandwidth of 60 GHz can realize high-speed wireless communications by transmitting high-capacity and uncompressed data at a speed of several gigabytes per second. However, current high-speed connectors adopt traditional designs. For example, a male connector usually uses a straight-line male terminal, and a female connector uses an elastic female terminal. When the two are mated with each other, the straight-line design of the male terminal tends to leave stub. Especially, in high-speed operation, stub phenomenon will affect the transmission performance of a high-speed and high-frequency signal.
Therefore, it is necessary to provide a high-speed signal terminal and a high-speed connector assembly that can eliminate stub and maintain the highest frequency of the bandwidth to 60 GHz.
The primary object of the present invention is to provide a high-speed signal terminal with a U-shaped fork structure which can facilitate engagement and shortening the engaging length so as to eliminate stub.
Other object of the present invention is to provide a differential signal terminal pair, including a first differential signal terminal pair and a second differential signal terminal pair. When the first and second differential signal terminal pairs are engaged with each other, the two can be mated in a criss-crossed manner (or in a quasi-star manner), so as to shorten the engaging length and eliminate stub.
Another object of the present invention is to provide a high-speed connector assembly, including a first high-speed connector and a second high-speed connector. When the first and second high-speed connectors are engaged with each other, the two can be mated in a criss-crossed structure (or in a quasi-star structure), so as to shorten the engaging length and eliminate stub, thereby maintaining the highest frequency of the bandwidth to 60 GHz.
