Protection of unsealed electrical connectors

摘要

A monitoring system for connector pins exposed to conductive/corrosive fluids and/or corrosive environments includes a first sensing portion having a pin monitoring section configured to measure a pin current flow of at least one conductor pin, and transfer a first signal. A second sensing portion produces a second signal indicating by a contactless determination the presence of a fastener providing physical connection between an interface member and a component. A decision logic device receives the first and second signals, compares the pin current flow to a predetermined range of values, and isolates electrical power to the conductor pin when the first signal indicates the pin current flow is outside the predetermined range of values. A sensor body created of a non-ferrous material and connected to the component includes a first insert member having the conductor pin and a second insert member defining a sensor sensing proximal presence of the fastener.

1. A monitoring system for conductor pins exposed to conductive/corrosive fluids, comprising:
a first sensing portion having a pin monitoring section to measure a pin current flow of at least one conductor pin, compare the pin current flow to a predetermined range of values, and produce a first signal indicative of the pin current flow; and a second sensing portion configured to produce a second signal indicative by a contactless determination the presence of a fastener providing physical connection between an interface member and a component having the at least one conductor pin positioned therein; and a decision logic device to receive the first and second signals and isolating electrical power to the at least one conductor pin when the first signal indicates the pin current flow of at least one conductor pin is outside of the predetermined range of values.
