Abstract

This article describes a cam-action connector for establishing a mechanical interlock and electrical connections between adjacent modular units. The connector plugs into mirror image recesses in adjacent vertical walls of the modular units and includes spring contacts for providing a bridge between printed conductors on circuit boards within the modular units. Fig. 1 illustrates one type of modular terminal in which the connector to be described could be used. The terminal consists of several free-standing modular units 10A through 10F. Each of the modular units would have a dedicated function suitable for a terminal. Units 10A-10C could be printers, displays, processors, etc. Units 10D-10F might be keypads.

Electromechanical Connector for Modular Terminal

This article describes a cam-action connector for establishing a mechanical interlock and electrical connections between adjacent modular units. The connector plugs into mirror image recesses in adjacent vertical walls of the modular units and includes spring contacts for providing a bridge between printed conductors on circuit boards within the modular units. Fig. 1 illustrates one type of modular terminal in which the connector to be described could be used. The terminal consists of several free-standing modular units 10A through 10F. Each of the modular units would have a dedicated function suitable for a terminal. Units 10A-10C could be printers, displays, processors, etc. Units 10D-10F might be keypads. A terminal is assembled by electrically and mechanically connecting suitable modules using a cam-type connector 12 using a generally C-shaped spring contact 14 to provide a bridge between printed circuit cards in adjacent modules. In Fig. 1, only printed circuit card 16 within module 10A is shown. The terminal is preferably of a type which uses a closed chamber as a data communications medium between adjacent units. In this type of terminal, the printed circuit board would be used as a power distribution board. Fig. 2 is a plan view of the connector 12. In this view, the connector is roughly butterfly-shaped and is seated in mirror image recesses in adjacent vertical walls of adjacent modular units. The modular...
