  • Page 51: Connector Types

    Service manual Disassembly and repair 45 Connector types Disassembly and repair procedures require that you disconnect and reconnect the following connector types inside the device: • 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.
  • Page 52 ® 46 Disassembly and repair Connex Spot Monitor • ZIF (zero insertion force): The device uses flex cables and ZIF flex cable connectors. Flex cables and ZIF connectors require special care when handling. ZIF connectors use a sliding outer piece that latches and unlatches to secure and release the flex cable.
  • Page 53 Service manual Disassembly and repair 47 • Coaxial: Coaxial connectors, a type of pressure connector in this case, are components attached to the ends of a coax cable—they make it possible to connect to other devices. The connector has a wire conductor in the center, surrounded by an outer conductor, and an insulation between the two.
