8.4 Common Power and Signal Connectors
When pulling a connector plug from a jack, do not pull on the 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 45. To disconnect
the ribbon cable, push out the plastic clips on the sides to unlock
the cable and then remove the jack.
Figure 45: Ribbon
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 Block
Termination Blocks:
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 46.
Phoenix ™ -Style Connectors:
Figure 47: Phoenix
Connector
Phoenix connectors, which are usually green, are often used for
communication signal termination on circuit boards. Refer to
Figure 47. 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.
Figure 48: Mate-
n-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 48 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.
