Teaching or circuit fault finding aid - comprising contact socket matrix and connecting circuit selector plug

摘要

The aid is for demonstrating or checking electronic circuits and comprises a base board (2) with a matrix (3) contact sockets (311,...3mm) with each socket brought out individually to a multipin connector (5). Interconnection between the sockets of the matrix is made in a selector plug (4) which can be engaged with the connector (5). A further input and measuring instrument connector can be plugged into the selectors. The demonstration or teaching circuit (6), typically a permanently wire board, is plugged into the matrix through defined pin positions (8...,7..), and the connection between it and a test instrument made by the selector plug. A similar procedure may be adopted to test faulty circuits.
