Abstract
An interconnection device for interconnecting a number of first terminals to a number of second terminals. The interconnection device includes a conductive housing and a number of contacts that are insulated from the conductive housing. This configuration may provide shielding to the number of contacts from outside sources of electro-magnetic interference. Further, a number of conductive ribs may be provided between adjacent contacts, thereby shielding the contacts from cross-talk interference between adjacent contacts. Finally, the impedance of each contact in the interconnection device may be controlled to provide a stable bandpass, and may be programmable to match, or correct for, the input impedance of a corresponding device.
Claims24
Apparatus for electrically interconnecting a first terminal to a second terminal and controlling impedance of the interconnection, comprising:
- (a) a housing having a portion which is electrically conductive, said housing having a number of slots formed therein;
- (b) a sleeve provided in a preselected one of said number of slots of said housing and having a portion which is electrically insulative, said sleeve forming a contact receiving slot;
- and
- (c) a contact selected from a plurality of contacts having different areas and disposed in said contact receiving slot formed by said sleeve, at least a portion of said contact being electrically conductive, and said sleeve electrically insulating the portion of said contact that is electrically conductive of said contact from the portion of said housing that is electrically conductive;
- (d) whereby when said first terminal and said second terminal engage said contact, said contact electrically connecting said first terminal to said second terminal;
- (e) wherein a portion of a wall defining said sleeve overlying said contact is removed to define at least one aperture, said sleeve in combination with said selected contact effecting serial matching of impedance along a connection of said first terminal to said second terminal through said contact.
