Abstract
Abstract Connectors with capacitors or resistors built in are very expensive and a custom design requires a considerable lead time. By building a circuit in modular form so that it connects to a standard cylindrical connector, both the cost and lead time are reduced drastically. Modules containing a variety of frequently used circuitry can be kept in inventory for at-will and immediate association with any standard circular connector, as desired. By having a variety of adapter collars in stock that mate with various kinds and constructions of cylindrical connectors, the suppression modules may be connected to a variety of differently constructed connectors. Many different configurations for the electrical circuitry in the module are possible. Many different configurations of the circuit module and interface collar are possible and can be designed to accommodate almost any connector configuration. By utilizing a terminating module as well, the connector with its circuit module attached can be utilized like and appears to be a single connector. A metal oxide varistor in compact plate form is uniquely suited for use in multi-pin connector bodies or in circuit modules.
