Frequently Asked Questions
Q: What is the purpose of the PR 201267 return spring in a lift truck charger connector?
A: The PR 201267 is a return spring that retracts the movable contact tip after the charger plug is removed from the receptacle. It ensures the connector resets to its open position for the next charging cycle and prevents contact tips from remaining in the extended position, which could cause accidental contact or mechanical binding.
Q: What material and specifications define the PR 201267 return spring?
A: Return springs are typically made from stainless steel or music wire with a low spring rate designed to extend or retract smoothly without mechanical resistance. Verify the spring constant (lbs/in), free length, and coil diameter. The spring must be strong enough to close the connector reliably but not so stiff that it damages the contact sleeve or housing.
Q: How do I know if the PR 201267 return spring has failed and needs replacement?
A: Failed return springs show signs of rust, reduced tension, or permanent deformation. Symptoms include the movable contact tip staying extended after disconnecting the charger plug, or requiring manual pressure to reset. A weakened spring reduces contact pressure and can cause intermittent charging or complete connection failure.
Q: Can the PR 201267 be cross-referenced with other return spring SKUs or is it model-specific?
A: Return springs are model-specific. The PR 201267 is configured for specific connector block geometry and contact tip design. Do not substitute with other spring SKUs without confirming the connector block part number and contact tip assembly type. Incorrect springs cause mechanical binding or poor connector reset.
