ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to electrical connectors and particularly to shielded, high speed connectors.
2. Brief Description of Prior Developments
As signal speeds, in particularly data transfer speeds, have increased, interconnection systems, such as those used for input output terminals for data processing equipment have had to be designed to pass these higher speed signals within acceptable limits of signal degradation. These efforts have involved shielding and impedance control. Such efforts are typified with connectors, such a modular jacks, that have separate metal shields applied over the connector housing. In many instances, these shields are in two parts, one to cover the body of the connector and the other to be applied over the front face of the connector. Similar approaches have been taken for other connectors, such as the HSSDC connector marketed by AMP, Inc., which is designed to meet the ANSI X3T11 Fiber Channel committee standards. However, as signal speeds have increased, the difficulty of meeting impedance control and shielding requirements by the use of such wraparound shields has increased. An additional complication is that these interconnection systems require reliable contact with shielding structures on the mating plug connectors so that overall performance of the interconnection system is maintained.
Another approach that has been taken is illustrated in recent designs of Universal Serial Bus connectors. Recent designs utilize a central insulative molded member to retain the contacts. The outer shell of this connector comprises a formed sheet metal shield that is wrapped about the molded member and forms the walls of the connector housing. One such connector has been marketed by Berg Electronics under the part number designation 87520.
While the above described connectors have been able to achieve adequate performance in terms of minimizing signal degradation at high frequencies, the drive for ever higher signal frequency has necessitated the development of connectors with higher performance capabilities.
SUMMARY OF THE INVENTION
High speed interconnection performance is assured according to the present invention by incorporating latching features directly into a metal shield of the board mounted receptacle connector. In a preferred embodiment, metal latch engagement surfaces are formed directly from bent portions of the metal shield.
Shielding performance is enhanced by providing opposed laterally extending flanges on the shields. The flanges have interfitting structures arranged along an outer edge or distal so that the flanges of adjacent connectors can be interfit, thereby enhancing shielding integrity and minimizing space requirements.
Contacts for establishing electrical connection between the shield of the receptacle conductor and the mating plug connector have a flexural axis extending generally in alignment with the insertion axis of the mating connector. These contacts are canted inwardly from the shield and can be additionally compliant toward and away from the flexural axis. In a preferred embodiment, these contacts are formed integrally with the sheet metal shield.
Also encompassed within the invention is an apparatus for mounting an electrical connector on a PCI bracket comprising a base containing a plurality of apertures and at least one spring loaded eject pin, a contact support plate having a plurality of slots used to position contact tails on the connectors, a vertical clamp used to hold the connectors in place and a spring loaded plunger positioned in the base such that the PCI bracket is accurately positioned with respect to the connectors.
