Problems solved by technology
[0009] Although the electrical connector disclosed in the '827 patent and other currently available differential pair electrical connector designs generally provide satisfactory performance, the inventors of the present invention have noted that at high speeds (such as frequencies of 3 GHz or higher), currently available The design of the electrical connector may not adequately provide the desired minimum crosstalk, impedance and attenuation mismatch characteristics
[0010] These crosstalk, impedance and attenuation mismatches are more pronounced when electrical connectors use single-ended signals rather than differential signals

Embodiment Construction
[0038] Referring to FIG. 1, FIG. 1 shows an electrical connector assembly according to one embodiment of the present invention. The electrical connector assembly 10 includes a first electrical connector 100 matable with a second electrical connector 200 .
[0039] The first electrical connector 100, at figure 2-8b is described in more detail, it includes a plurality of thin plates 120, each of the plurality of thin plates 120 has: an insulating shell 122; a plurality of signal conductors 124 (see Figure 3); and a plurality of shielding strips 126 (see Figure 5a and 5b). For purposes of example only, the first electrical connector 100 is depicted as having ten sheets 120 each having fourteen single-ended signal conductors 124 and corresponding fourteen shielding bars 126 . However, as will be more clearly described later, the number of sheets and the number of signal conductors and shielding strips in each sheet will vary according to requirements.

In one embodiment of the invention, there is disclosed an electrical connector connectable to a printed circuit board on one end, which includes an insulative housing and a plurality of insulative posts disposed in the insulative housing, with the insulative posts arranged in at least one row. Each of the insulative posts has a first side and a second side, and the insulative posts extend in a direction away from the printed circuit board. A plurality of signal conductors are provided, with each signal conductor having a first contact end connectable to the printed circuit board, a second contact end, and an intermediate portion therebetween that is disposed in the insulative housing, wherein the signal conductors are disposed along the first side of the insulative posts. A plurality of ground conductors are provided, with each ground conductor having a first contact end connectable to the printed circuit board, a second contact end, and an intermediate portion therebetween that is disposed in the insulative housing, wherein the ground conductors are disposed along the second side of the insulative posts such that the signal conductors and the ground conductors are electrically isolated from one another.
Description
technical field [0001] The present invention relates to an electrical connector assembly for interconnecting a plurality of printed circuit boards. More particularly, it relates to a high speed, high density electrical connector assembly that provides improved minimized crosstalk and improved attenuation and impedance mismatch characteristics. Background technique [0002] Electrical connectors are used in many electronic systems. It is often simpler and less costly to fabricate a system on several printed circuit boards (PCBs) and then connect the PCBs to each other with electrical connectors. The traditional solution for connecting several PCBs is to use one PCB as the backplane. Other PCBs called daughter boards or daughter cards are then connected through the backplane with electrical connectors. [0003] Electronic systems are often becoming smaller, faster and more complex in function. This means that in recent years, the number of circuits and thus the operating f...
