Abstract

The invention provides a high-speed high-density backboard connector with a modularized structure. The electric connector comprises a pore connector and a pin connector, wherein the pore connector comprises a casing, a cover plate and a plurality of veneer sheet components; and the pin connector comprises a pedestal, a laterally-grounded shielding piece and differential pair signal pin units. The pin connector adopts the modularized structure. The differential signal pin units and the laterally-grounded shielding piece are arranged in the pedestal in a dense array. The modularized structure is fixed in the pin connector by adopting the interference fit or the double-wedge. Compared with the prior art, the backboard connector has the advantages of stable, compact and easily-expansible structure, complementary shielding and high-density and high-quality signal running characteristic.

Description

1. Technical field [0001] The present invention relates to electrical connectors for use in electronic systems, and more particularly to high speed high density backplane connectors of modular construction for transferring high speed signals between printed circuit boards in electronic components. 2. Background technology [0002] At present, in some large-scale electronic equipment or communication systems, the data and control signals between multiple line cards, the main control resource board and the switching network card are all connected through the backplane. Existing backplanes are printed circuit boards with many connectors, and conductive traces on the printed circuit board are connected to signal pins in the connectors so that signals can be sent between the connectors. Daughterboards also contain connectors that plug into connectors on the backplane. In this way, signals are sent between daughter boards via the backplane. [0003] Under this structure, as the ...
