Automotive Connector Back Cover – 1-936050-1, Waterproof Housing Rear Seal for Female Socket Cable Plug

Part number 1-936050-1 is a TE Connectivity (formerly AMP/Tyco) automotive connector back cover — the rear seal and secondary lock component for a specific female socket connector housing. The TE Connectivity part number format (X-XXXXXX-X) identifies this as a TE-manufactured accessory. Back covers are critical for achieving IP67 sealing and secondary terminal retention in waterproof automotive connectors.

Key Specifications

• Part Number: 1-936050-1
• Manufacturer: TE Connectivity (formerly AMP/Tyco)
• Component Type: Connector back cover / rear seal / secondary lock
• Material: PA66 nylon, flame retardant
• Function: IP67 rear seal + secondary terminal retention
• Application: Specific TE Connectivity female socket connector housing (verify compatibility)

Why Back Covers Are Critical

• IP67 sealing: The back cover compresses individual wire seals against the housing rear face. Without the back cover, wire seals are not compressed and water enters through the rear of the housing — the connector will not achieve IP67 regardless of how well the mating face is sealed.
• Secondary terminal retention: The back cover locks over terminal lancing lances, preventing push-back under cable pull forces. This is especially important in high-vibration environments (engine bay, underbody) where cable movement can gradually push terminals out of their housing cavities.
• OEM requirement: Most OEM waterproof connector specifications require the back cover to be installed for the connector to meet the vehicle manufacturer’s electrical system requirements.

Frequently Asked Questions

How do I verify 1-936050-1 is compatible with my connector housing?

Cross-reference 1-936050-1 in the TE Connectivity catalog (te.com) to identify the compatible connector housing part numbers. The back cover is designed for a specific housing — it will not fit other housings even if they have the same pin count. Verify the housing part number against the TE catalog before ordering the back cover.

What happens if I install the wrong back cover?

An incorrect back cover will either not fit (too large or too small) or will fit but not compress the wire seals correctly (wrong cavity geometry). A back cover that appears to fit but does not compress the wire seals will not achieve IP67 — the connector will pass water even though the back cover appears installed. Always verify the back cover part number against the housing part number.

Can I reuse a back cover after removing it?

Yes, if the back cover is undamaged. Inspect the back cover for cracks, deformed locking tabs, and damaged sealing surfaces before reuse. A cracked or deformed back cover will not achieve IP67 sealing — replace it. Back covers that have been removed and reinstalled multiple times may have reduced locking tab retention force — replace if the back cover does not click firmly into the locked position.

Typical Applications

• Automotive repair: Replacing missing or damaged back covers on TE Connectivity waterproof connectors
• Harness manufacturing: Back covers for new TE Connectivity connector assemblies
• Commercial vehicles: Back cover replacement during connector repair on trucks and buses
• Automotive workshops: Workshop stock for TE Connectivity connector accessories
