Title: Electronic chassis back wiring co-ordinate positioning system - locates wrapped connections in repair and maintenance of systems such as telephone exchanges
Inventor: LUCKMANN GUENTER
IPC: H05K13/06
Filed: 1974-09-30
Abstract: On a telephone exchange chassis to locate a particular pin connection entails a considerable amount of counting to find the appropriate rowand column of that pin. The apparatus provides a simple numbering system and location facility to assist in this task. It consists basically of a numbered scale (5) down each side of the matrix of connections, with each number representing a particular row of connectors. Across the matrix, and mounted on these scales is a transverse numbered scale (8) which can slide to and fro over the original scales. The geometry of the contact between these two sets of scales may consist of one of several alternative forms. To locate any position the transverse scale is slid to the correct row and the appropriate column is simply read off.
