The high-speed backplane connector is used for connecting a single board and a backplane, and the single board and the backplane form a 90-degree vertical structure to transmit high-speed differential signals. The influence of the structure of the connector on the signal transmission rate is very important.
A contact structure of a first prior art connector contact area is shown in fig. 1. The female end ground pin and the male end ground pin realize single-point contact in the contact area, and the female end terminal is forked into two small terminals in the contact area. This contact scheme, with only one contact, has poor performance at higher rates for insertion loss and crosstalk. Meanwhile, the coplanarity of the two small terminals at the female end cannot be guaranteed, and the risk of Pin falling exists.
A second prior art contact configuration for a connector contact area is shown in fig. 2 and 3. The female ground terminal splits into three small terminals at the contact area. One terminal makes a first contact with the male ground terminal to form a contact point I, and the other two terminals make a second contact with the male ground terminal to form a contact point II. And the three small terminals improve the insertion loss and crosstalk performance in a front-rear contact mode. The disadvantage of this contact is that the female ground terminal splits into three terminals, which are difficult to machine. Simultaneously, two little terminals of contact II have the pin risk of falling.
A third prior art contact configuration for a connector contact area is shown in fig. 4. Female terminal, shielding piece bullet are grabbed and are located the both sides of public needle respectively, pass through the mode of front and back contact at the contact zone, improve insertion and decrease and cross talk performance. The contact mode has the defects that the top end of the male pin needs to be chamfered on two sides, and the contact area of the male pin needs to be plated with gold on two sides, so that the processing difficulty and the cost are increased.
