However, when this connector is mated in place, a large part of the plug shielding sheet 92 hangs over the front side of the shrapnel 84, forming a short pile. When the differential pair passes through a high-speed signal, the formed short pile itself generates antenna radiation. , which interferes with the signal transmission of the differential pair

Embodiment Construction
[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0031] Specific embodiments of the connector assembly of the present invention, such as Figure 2~3As shown, the male end connector 8 and the female end connector 9 are included, the male end connector 8 and the female end connector 9 are respectively provided with male end and female end contact modules 80, 90, and the male end and female end contact modules are The male end and female end contact units 81, 91 constitute a contact assembly. The male end contact unit 81 includes a male end differential pair 83 and a male end shielding sheet 82 , and the female end contact unit 91 includes a female end differential pair and a female end shielding sheet 92 . Wherein, both the male-end shielding sheet 82 and the female-end shielding sheet 92 are slot-shaped shielding sheets with a U-shaped cross section. The extending direction of the slot-shaped shieldin...

The present invention provides a contact unit, a contact module, a connector and a connector module. The contact unit comprises differential pairs and groove-shaped shielding pieces relatively fixedlyarranged with the differential pairs, the two side walls of the groove-shaped shielding pieces are respectively located at the two sides of the differential pairs, the groove walls of the two sides of the groove-shaped shielding pieces are provided with at least two contact portions being in contact with the adaptive groove-shaped shielding pieces, at least one of the contact portions is internally provided with a front contact portion, the at least one front contact portion is located at the front ends of the groove-shaped shielding pieces and is configured to be in contact with the front ends of the adaptive groove-shaped shielding pieces, at least one of the contact portion is a rear contact portion, the at least one rear contact portion is located at the rear ends of the groove-shapedshielding pieces and is configured to be in contact with the rear ends of the adaptive groove-shaped shielding pieces. When insertion of two shielding pieces is performed, the front and rear contactportions are in contact at front and back positions, and therefore, formation of a short pile can be avoided on any one shielding piece, the antenna effect is eliminated, and it is avoided that the shielding pieces themselves generate interference on the differential pairs shielded by the shielding pieces.
Description
technical field [0001] The invention relates to the field of conductive connection, in particular to a contact unit for conductive connection, a contact assembly including the unit, a connector and a connector assembly. Background technique [0002] Crosstalk refers to the undesired voltage noise interference on adjacent transmission lines due to electromagnetic coupling when a signal propagates on a transmission line. Signals are transmitted in the transmission line in the form of electromagnetic waves. Electromagnetic waves include time-varying electric and magnetic fields. The transformed electric and magnetic fields will generate induced voltages and currents in the surrounding transmission lines. The voltage and current are the direct causes of the crosstalk behavior in the disturbed transmission line. [0003] Crosstalk is another important factor affecting the transmission performance of products. Reducing crosstalk has always been an important direction in the desig...
