Abstract

This article describes a connector which permits a daughter board to be mechanically and electrically connected to a mother board through a slightly resilient elastomeric member wrapped with parallel conductive stripes. The stripes on the elastomeric member are brought into registration with conductors on both the mother and daughter boards using complementary tabs and slots on the two boards. (Image Omitted) Referring to Fig. 1, electrical connections between parallel conductors 10 on the bottom surface of the daughter board 12 and similarly-spaced, parallel conductors 14 on the top surface of a mother board 16 are made through an elastomeric connector 18 consisting of an oval body 20 wrapped with a sheet of narrow conductive stripes 22 having narrower spacing than the conductor patterns 10 and 14 on the two boards.

Snap-In Board-To-Board Elastomeric Connector

This article describes a connector which permits a daughter board to be mechanically and electrically connected to a mother board through a slightly resilient elastomeric member wrapped with parallel conductive stripes. The stripes on the elastomeric member are brought into registration with conductors on both the mother and daughter boards using complementary tabs and slots on the two boards.

Referring to Fig. 1, electrical connections between parallel conductors 10 on the bottom surface of the daughter board 12 and similarly-spaced, parallel conductors 14 on the top surface of a mother board 16 are made through an elastomeric connector 18 consisting of an oval body 20 wrapped with a sheet of narrow conductive stripes 22 having narrower spacing than the conductor patterns 10 and 14 on the two boards. The narrow conductive stripes provide redundant electrical connections between corresponding conductors on the two boards. A retaining tab 24 extends from one edge of the elastomeric connector
18. The connector can be used to provide drop-in field installation of options where each option includes a dedicated daughter board. In this use, the elastomeric connector 18 is preassembled to the daughter board 12 during manufacture of the option. The connector 18 is dropped into a central opening 26 in a shroud 28 with tab 24 being received in a recess 30 in the shroud. The shroud 28 is attached to the daughter board 12 using conventional screws, one of which 32 is illustrated. The elastomeric connector is trapped between the bottom surface of daughter board 12 and shroud 28 by the tab 24. The option including the daughter board 12 and the elastomeric connector may be covered by a decorative or functional cover 35. The mother board 16 to which the option is to be connected will be...
