Installation of DC Connectors
It is a given that normal wear from extended use of DC connectors
can eventually show signs of heat damage resulting from a poor connection
with a mating connector. However, over the years we have seen numerous
DC connectors with heat damage resulting from improper installation
of the connector itself. An improperly installed connector used in a
power circuit can easily become a potential source of fire.
Many of the melted
and burnt connectors seen on chargers returned for service have been
received with both halves of the connection in a melted/burnt "glob".
To determine the cause of the heating required X-raying the "glob"
to inspect the electrical components of the connectors. The most common
cause seen is improperly crimped connections, many times without the
required reducing bushings for smaller gauges of wire.
Always make sure
these connectors are installed per the manufacturer's installation instructions.
Most manufacturers offer crimping tools specially designed for their
products to ensure a proper mechanical and electrical connection is
made. We also suggest that after properly crimping the contacts, a good
solder joint will help ensure a good connection and avoid a potential
liability situation. Another alternative, Lester Electrical not only
offers replacement DC connectors but also offers complete DC cordsets
with the connector installed.
