Integrated en-style auxiliary barrier connector
View Patent ↗Techniques disclosed herein include a conversion technique that converts an aircraft circuit breaker having male auxiliary connectors (micro switch connectors) to an aircraft circuit breaker having female auxiliary connectors, such as those conventionally used on European-made aircraft. Techniques include adding a barrier to a conventional aircraft circuit breaker approved for U.S. markets. This barrier includes female auxiliary connectors integrated with the barrier, as well as a flexible circuit that connects the male connectors with the female connectors such that the female connectors can still receive separate male connectors in the female receptacles. Such a technique converts conventional aircraft circuit breakers into a European-style breaker without requiring a full European rebuild and re-qualification. Embodiments can include single and multiple phase versions, and configurations for use with high and low amperage.
