In order to address the above problem; Said differential contact elements assembly adopts following technical scheme: the differential contact elements assembly, comprise the differential pair that constitutes by two differential contact elements more than two, and be provided with grounding component between adjacent two differential pairs; Also comprise ground plate; Said differential pair and grounding component all are fixedly set on the same side surface of said ground plate, two differential contact elements of wherein said each differential pair all with the ground plate insulation coordination, said grounding component and ground plate electrically connect.
Said ground plate is provided with single-ended contact, is provided with grounding component between said single-ended contact and the adjacent differential pair.
Said differential pair, grounding component and single-ended contact are set up in parallel.
Each contact of said differential pair all has first contact pin, and said grounding component has second contact pin, and said single-ended contact has the 3rd contact pin, the parallel to each other and extension in the same way of said each first, second, third contact pin.
Said second contact pin protrudes in said the first, the 3rd contact pin on its grafting direction.
Said differential connector adopts following technical scheme: differential connector; Comprise housing and be assemblied in two above differential contact elements assemblies in the said housing from top to bottom successively; Said differential contact elements assembly comprises the differential pair that is made up of two differential contact elements more than two; Adjacent two contacts between be provided with grounding component, also comprise ground plate, said differential pair and grounding component all are fixedly set on the same side surface of said ground plate; Two differential contact elements of wherein said each differential pair all with the ground plate insulation coordination, said grounding component and ground plate electrically connect.
Said ground plate is provided with single-ended contact, is provided with grounding component between said single-ended contact and the adjacent differential pair.
Said differential pair, grounding component and single-ended contact are set up in parallel.
Each contact of said differential pair all has first contact pin, and said grounding component has second contact pin, and said single-ended contact has the 3rd contact pin, the parallel to each other and extension in the same way of said each first, second, third contact pin.
Said second contact pin protrudes in said the first, the 3rd contact pin on its grafting direction.
Because said differential contact elements assembly is provided with said grounding component and said differential pair and grounding component is arranged on the said ground plate between adjacent two differential pairs; Grounding component and said ground plate electrically connect; Therefore can effectively suppress crosstalking between the two differential contact elements assemblies of range upon range of setting in use; Guarantee the reliability of signal transmission, solved the problem that to crosstalk between the adjacent two differential contact elements assemblies of existing electric connector.
