How to Install or Connect LVDS Micro Coax Cables

 

When working with LVDS micro coax cables, the process involves careful handling of both the cable and the connectors. Here are the key steps:

1. Power Off the Device

• Before you begin any installation or disconnection process, turn off the device to avoid damaging sensitive components.

2. Identify the LVDS Cable and Connectors

• The LVDS cable typically has multiple small coaxial wires (usually two) that are used for the differential signal transmission.
• These cables will usually connect to micro coax cable assembly connectors (often a small, square, or rectangular connector), which are located on the LVDS controller and the display module.

3. Inspect the Cable and Connectors

• Ensure the cable is in good condition and check for any damage to the shielding or center conductors.
• Look for corrosion or dirt on the connectors, as this can cause poor connectivity or signal issues.
• If any components appear damaged, replace them before continuing.

4. Prepare the Cable

• Stripping the Cable: If you are installing a new LVDS micro coax cable, you may need to strip the cable. Carefully strip off the outer insulation of the cable, taking care not to damage the shielding or inner conductors.
• Bend Radius: Ensure you do not excessively bend the cable, as micro coax cables are more fragile than regular wiring and can be damaged if bent too sharply.

5. Insert the Cable into the Connector

• Micro Coax Connectors: These are often spring-loaded connectors or push-in connectors. Make sure that the center conductor is aligned properly with the corresponding connector slot. The shielding (outer conductor) should also make good contact with the shield area inside the connector.
• Carefully insert the cable into the connector. You might need to press down gently or use tweezers to guide it into place if it’s a tight fit.
• For push-to-lock connectors, once the cable is in place, it will automatically lock. For spring-loaded connectors, you may need to gently press the connector into place and ensure it's securely locked in.

6. Secure the Cable

• Once the cable is seated correctly, make sure the connection is firm and secure.
• Some LVDS setups use small clips or latches to hold the connectors in place. Ensure these are properly latched or snapped into place.

7. Check for Correct Orientation

• The connectors for micro coax cables are often keyed (have a specific shape) to ensure they are inserted in the correct direction. Don’t force the connector into the slot. If the cable doesn't go in smoothly, double-check its orientation.

8. Test the Connection

• After installation, power on the device and verify that the display is functioning correctly. Check for any signs of signal interference, flickering, or a distorted screen. If the display is working properly, the cable installation was successful.

Troubleshooting Tips:

• No Signal or Flickering Display: If the display isn't showing a clear image, check the connection for any loose or poorly seated cables. Inspect the cable and connectors for damage.
• Signal Interference: Ensure that the cable is routed away from high-power components or other sources of interference. Coax cables are shielded to prevent this, but physical placement can still affect performance.
• Loose or Broken Connection: If the connectors don't click into place or feel loose, ensure that the micro coax cable is properly inserted and securely locked into place. If the connection seems unreliable, replace the cable or connector.
