Crossover Connector

In order to connect signal lines from two parallel circuit boards, cable connector assemblies had been used. This crossover connector gives the connection in less space and with fewer parts, while maintaining the required impedance across the connection.

The two boards 11 and 13 have top and bottom copper ground planes 15 and 17 and internal signal lines 19. End recess 21 and slot 23 are formed in each board to give top and bottom access to the signal lines. Flat metal base 25 is positioned between the two boards so that square plastic spacers 27 and 29 abut the ends of the boards.

The projecting end of the base has flat curved surface 31 and carries another spacer 33. Connecting wire 35 is mounted in the spacers and has flat end tabs 37 and 39 which are soldered to the signal line of each board. Filler plugs 40 are placed in the signal line recesses. Two cap members 41 and 43 encase the connecting wire and the ends of the board and mount the spacers. The cap members and base provide the necessary electrical ground contact. The accurately controlled air separation of the connecting wire provides the dielectric for the proper impedance from one board to the other.
