Installation and Usage Guidelines
Proper installation is essential to ensure the DB39 13405 performs reliably over its lifespan. Incorrect termination or poor strain relief can lead to signal loss, intermittent faults, or physical damage. Follow this step-by-step guide for optimal results:
- Cable Preparation: Strip the outer jacket of the cable to expose the individual conductors. Ensure the length matches the connector’s contact depth requirements. Twist and tin stranded wires to prevent fraying and ensure solid solder joints.
- Contact Attachment: Attach each wire to its designated contact using either soldering or crimping. For soldering, avoid cold joints by applying adequate heat and rosin-core solder. For crimping, use a calibrated crimping tool compatible with the contact type to ensure a gas-tight connection.
- Insertion into Housing: Carefully insert each contact into the correct position in the DB39 housing. Pins and sockets have specific locations—do not interchange them. Use the locking mechanism (if present) to secure contacts and prevent backout during mating.
- Shield Termination: For shielded cables, connect the braided or foil shield to the connector’s metal shell using a pigtail or 360-degree clamp. This ensures effective EMI protection and grounding.
- Backshell Installation: Slide the rear backshell over the cable and secure it to the connector body. Adjust the strain relief clamp to firmly grip the cable jacket without damaging the insulation. This prevents tension from transferring to the contacts.
Expert Tip: Always verify contact polarity and arrangement using the manufacturer’s pinout diagram before final assembly. Use a multimeter to check for continuity and short circuits after installation.
