3.1 Common Connectors
This display uses many different types of connectors for power and signal termination. Take special
care when disengaging any connector so as not to damage the connector, the cable or the circuit
board.
When pulling a connector plug from a jack, do not pull on the wire or cable; pull on the jack
itself. Pulling on the wires may damage the connector.
The following information presents some common connectors that may be encountered during display
maintenance. Not all of these connectors are found in every display.
1. Phone Jacks (RJ11/RJ45 Connectors):
RJ connectors, as seen in Figure 9, are similar to the telephone connectors found in
homes and are used on the ends of RJ45 cable. In order to remove this plug from the
jack, depress the small clip on the underside of the plug.
Before replacing an RJ connector, spray it with Deoxit
™
contact cleaner to remove
any foreign matter that may cause signal problems. In addition, apply a generous
amount of Cailube
™
protector paste to the plug before inserting it into the jack. This
paste will protect both the plug and the jack from corrosion.
2. Mate-n-Lok
J Connectors:
The Mate-n-Lok connectors found in this display are white and
come in a variety of sizes. Circuit boards often used 9-pin Mate-n-Lok
connectors while four-pin connectors and two-pin connectors are often used for
power connection. Figure 10 shows a four-pin Mate-n-Lok connector. To
remove the plug form the jack, squeeze the plastics locking clasps of the side of
the plug and pull it from the jack.
3. Ribbon Cable Connectors:
Daktronics uses a variety of ribbon cables and ribbon cable connectors. Figure
12 and Figure 11 illustrate two of the most commonly used ribbon cable
connectors. To disconnect ribbon cable connector #1,
squeeze the metal locking clips inward and pull the plug
out of the jack. To disconnect ribbon cable connector #2,
pull each of the plastic locking arms outward and remove
the plug.
Before replacing a ribbon cable connector, spray it with
Deoxit contact cleaner to remove any foreign matter that
may cause signal problems. In addition, apply a generous
amount of Cailube protector paste to the plug before
inserting it into the jack. This paste will protect both the
plug and the jack from corrosion.
