Abstract

This is a pluggable cable to printed circuit card, impedance matched connector for use where the circuit functions of high frequency, critical timing and phase relationship are present. The connection provides approximately the same impedance characteristics as the mating printed circuit card.

Pluggable Cable To Card Connector

This is a pluggable cable to printed circuit card, impedance matched connector for use where the circuit functions of high frequency, critical timing and phase relationship are present. The connection provides approximately the same impedance characteristics as the mating printed circuit card.

The connector housing 10 is metallic with ground plane contacts 11 pre assembled in it. This carries the ground completely through the connector with the same spacings as the card 12, i. e., contact patch and thickness between the signal line 13 and ground plane 14. Housing 10 also provides shielding, completely enclosing the contacts, giving the same effect as a pure coaxial connector of the bayonet slot connection type. Also, with the center conductor 15 of the coaxial cable 16 preassembled directly to contact 17, mating discontinuities are minimized.

A shield insert 18 is crimped over the cable shielding 19 before being assembled into the main metal housing 10. The nylon insulator 20 acts as a solder cap to hold contact 17 in place and stiffen it. Although housing 10 is shown as one piece, it can be divided coextensive with the length of the shield insert 18. The cable end and ground contact end are then separately assembled before being joined by screws through the cable end of the housing. For multilayer printed cards where there is more than one ground plane, mode or level, the ground plane contacts 11 can be in several layers and in...
