Abstract

A circuit unit comprises three boards, 2, 4 and 6 with groups of three terminals 1, 3 and 5 united by means of wire wrappings 8. Each unit consists of a bare board with two rows of vertical terminals on opposite edges of the board. Each unit is graduated in size so that they are nested one within the other with the terminals standing side by side ready for connection by wire wrap. The terminals 1 of the top board are shorter than the other two sets of terminals 3 and 5 so that a shoulder is formed on the wire wrap which holds down the top board.

Packaging Circuit Components

A circuit unit comprises three boards, 2, 4 and 6 with groups of three terminals 1, 3 and 5 united by means of wire wrappings 8. Each unit consists of a bare board with two rows of vertical terminals on opposite edges of the board. Each unit is graduated in size so that they are nested one within the other with the terminals standing side by side ready for connection by wire wrap. The terminals 1 of the top board are shorter than the other two sets of terminals 3 and 5 so that a shoulder is formed on the wire wrap which holds down the top board.

Since the terminals are made in a punch press operation, the edges are sharp. They are faced outwardly to bite into the wire wrap wire and make a tight connection.

With transistors 9 on the top board, resistances 10 etc., on the second board, and logical input and output connections 12 made to the extending terminals 5 under the third board, all connections are accessible and the active and inactive components are separated.
