Embodiment Construction
[0022] Referring to the accompanying drawings, the embodiment of the overlapping grounding and complementary shielding differential contact pair electrical connector of the present invention will be further described: a plug connector 10, which is composed of an insulating base 11, a grounding shielding sheet 12 and a differential contact pair 13. Among them, a plurality of differential contact pairs 13 are arrayed on the bottom surface 24 of the base according to a certain row spacing and column spacing, and several ground shielding sheets 12 are combined in a certain way and fixed on the bottom surface 24 of the base to isolate each differential contact. to 13.
[0023] Among them, the differential contact pair 13 , the grounding shielding sheet combined with front and back 15 , and the grounding shielding sheet combined with overlapping 16 and staggered layer 17 are arranged and installed at various positions in the plug connector 10 .

The invention relates to an electrical connector which is applicable to a high speed transmission overlapping grounding and complementary shielding differential contact pairs, comprising a plug connector. The plug connector is provided with a substrate, a grounding shield sheet and the differential contact pairs. Wherein, the substrate is provided with a butt guide groove and limits the array position of the grounding shield sheet and the differential contact pairs. Each differential contact pairs is processed to array according to a certain row distance and column distance. Each grounding shield sheet forms complementary shielding via a plurality of arrangement modes such as positive and negative combination, overlapping, staggering and so on. The method of complementary shielding makes each differential pairs isolated to each other, so as to separate out a plurality of non congruent differential pairs sections to reach aims of controlling impedance of each differential pairs and reducing crosstalk with each other and so on. The non congruent differential pairs sections are cross arranged with each other. The arrangement is symmetrical with a central point of the substrate bottom surface, and convenient to use and easy to extend.
Description
1. Technical field: [0001] The invention relates to an electrical connector connected between printed boards and between printed boards and wires in interconnection systems such as electronic communication, in particular to an electrical connector with overlapping grounding complementary shielding differential contact pairs. 2. Background technology [0002] In the electronic interconnection system, with the improvement of the operating frequency of equipment and systems in the fields of electronics and communications, the requirements for connectors are getting higher and higher. From the initial simple electrical connection, it is now necessary to meet Gbps-level data transmission. The high-speed interconnection requirements of high rate have experienced the development and update of several generations of products. This new type of high-speed transmission connector that can meet the Gbps-level data transmission rate needs to solve signal integrity problems such as impedan...
