Connector types
Disassembly and repair procedures require that you disconnect and reconnect the following
connector types:
• Locking (squeeze-release): Locking connectors use a latching mechanism to prevent
accidental disconnection during assembly and use. The latch is located on one end of a tab so
it may flex and lock into place when coupled with its matching connector. The tab provides a
lever to release the latch. When disconnecting, squeeze to provide pressure on the tab to
unlatch. Some connectors have multiple latches that require you to press multiple tabs to
release.
To remove a locking connector, squeeze the release lever and remove the cable.
To connect a locking connector, push the mating pieces together until the latch locks in place.
• Pressure: Pressure connectors use friction to prevent accidental disconnects.
To remove a pressure connector, grasp each connector mating half and pull the halves apart.
Caution Do not use excessive force to disconnect the connector.
Excessive force may result in pulling the mounted connector off the
circuit board.
To connect a pressure connector, grasp each connector mating half and insert one half into
the other.
• USB: USB connectors provide communications and power connectivity between the main
board and the monitor’s sub-systems and external devices. USB connectors use friction to
maintain the connection, but rarely require much force to connect or disconnect. The USB
cable can safely be removed from the mounted connector by simply pulling it out of the
connector. Two types of USB connectors are used: USB A-type and USB mini-B.
To remove a USB connector, grasp the connector and pull.
To connect a USB connector, grasp the connector and insert.
• ZIF (zero insertion force): The monitor uses flex cables and ZIF flex cable connectors. Flex
cables and ZIF connectors require special care when handling.
