Connector
wire or cable; pull on the plug head itself. Pulling on the wires
may damage the connector.
The power and communication signal connections in the displays use many
different types of connectors. The following information presents some
common connectors encountered during display installation and
maintenance.
Ribbon Cable Connectors:
A typical ribbon connector is shown in Figure 30. To disconnect the
ribbon cable, push out the plastic clips on the sides to unlock the cable
and then remove the jack.

Cable Connector
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.
Termination Blocks:

Termination Block
Figure 32: Phoenix
Connector
Termination blocks are commonly used to connect internal power to an
external power source. Power wires need to have one-half inch of
insulation stripped from the end of the wire prior to termination. Insert
wires into terminations and make sure the clamp holds the wire firmly.
A typical termination block is shown in Figure 31.
Phoenix
™
-Style Connectors:
Phoenix connectors, which are usually green, are often used for
communication signal termination on circuit boards. Refer to Figure 32.
Strip one-quarter inch of insulation from the wire prior to insertion. To
remove a wire, turn the corresponding screw counter-clockwise to
loosen the connector's grip on the wire. To insert a wire, push the bare
wire into the connector and turn the above screw clockwise to lock the
wire into place.

Lok Connector
Mate-n-Lok
™ Connectors:
The Mate-n-Lok connectors found in the displays are white and come in
a variety of sizes. Figure 33 illustrates a four-pin Mate-n-Lok
connector. To remove the plug from the jack, squeeze the plastic locking
clasps on the side of the plug and pull it from the jack.
