The first signal unit 100 may be disposed adjacent to the second signal unit 200. Referring to fig. 1, the left side structure shown in fig. 1 is a second signal unit 200, and the right side structure shown in fig. 1 is a first signal unit 100. Both the first signal unit 100 and the second signal unit 200 may be packaged in a plastic package (not shown).
Referring to fig. 2, at least one first differential pair 110 is disposed in the first signal unit 100, and each of the at least one first differential pair 110 has two first contacts 111, and the first contacts 111 are connected to ends of the first differential pair 110.
The first differential pair 110 includes a first differential pair long trace 112 and a first differential pair short trace 113, and the first differential pair long trace 112 has a width greater than the width of the first differential pair short trace 113. The first differential pair long wire 112 is connected to one first contact 111 of the two first contacts 111, and the first differential pair short wire 113 is connected to the other first contact 111 of the two first contacts 111.
The first ground traces 114 are distributed on both sides of each first differential pair 110, see fig. 1.
At least one second differential pair 210 is disposed in the second signal unit 200, and in particular, a plurality of second differential pairs 210 may be disposed. Each second differential pair 210 corresponds to two second contacts 211, and the second contacts 211 are connected to ends of the second differential pair 210. The second differential pair 210 includes a second differential pair long wire 212 and a second differential pair short wire 213, and the width of the second differential pair long wire 212 is greater than the width of the second differential pair short wire 213. The end of the second differential pair long trace 212 is connected to one of the two second contacts 211, and the end of the second differential pair short trace 213 is connected to the other of the two second contacts 211.
Each second differential pair 210 of the at least one second differential pair 210 has a second ground trace 214 on each side of the second differential pair 210.
In each signal unit 10 of the plurality of signal units 10, the first differential pair 110 corresponds to the second differential pair 210 one by one, and the intersection point is formed on the projection of the corresponding differential pair in the layering direction of the first signal unit 100 and the second signal unit 200.
Referring to fig. 3, at least one of the two first contacts 111 and at least one of the two second contacts 211 have an intersection point in the layered direction of the first signal unit 100 and the second signal unit 200.
The projections of the first differential pair long wires 112 and the first differential pair short wires 113 in the layering direction have overlapping portions with the projections of the second differential pair long wires 212 and the second differential pair short wires 213 in the layering direction. Specifically, there are at least two intersections between the projection of the first differential pair long trace 112 and the first differential pair short trace 113 in the layering direction and the projection of the second differential pair long trace 212 and the second differential pair short trace 213 in the layering direction.
The working principle of the electric connector provided by the embodiment of the application is as follows:
in the electrical connector provided by the embodiment of the application, the first signal unit 100 and the second signal unit 200 are stacked together along the layering direction of the signal units 10, the projections of the differential pairs of the adjacent signal units 10 are intersected, and the first differential pair long wires 112 and the first differential pair short wires 113 of the first signal unit 100 and the second differential pair long wires 212 and the second differential pair short wires 213 of the second signal unit 200 have intersection points. According to the twisted pair electromagnetic shielding principle, the first differential pair 110 and the second differential pair 210, which are intersected by the projection of the first signal unit 100 and the second signal unit 200 in the layering direction of the signal unit 10, may form two closed loops in space during the signal transmission process. When interference exists, the directions of magnetic fields formed by the interference signals in the two loops are opposite, the two magnetic fields cancel each other and weaken, and the interference signals of the first differential pair 110 and the second differential pair 210 which are intersected by the projection of the layering direction of the signal unit 10 are self-shielded.
Referring to fig. 4, for the first differential pair 110, the width a of the first differential pair long trace 112 is greater than the width B of the first differential pair short trace 113, and if the width of the first differential pair long trace 112 is consistent with the width of the first differential pair short trace 113, the resistance of the first differential pair long trace 112 will necessarily be greater than the resistance of the first differential pair short trace 113 because the length of the first differential pair long trace 112 is longer than the length of the first differential pair short trace 113.
Therefore, the width of the first differential pair long wire 112 is widened, and the resistance value of the first differential pair long wire 112 can be changed, so that the impedance matching of the first differential pair long wire 112 and the first differential pair short wire 113 is realized, further the delay matching in the differential pair is realized, and further the high-speed performance of the product is improved.
