The TE Connectivity 1-1418639-5 is a 2-position single-row socket housing from the Micro Quadlok series, designed for wire-to-wire or wire-to-board interconnects where a compact, positive-locking connector is needed. The housing carries a Terminal Position Lock (TPA) feature, which locks each crimped terminal into its cavity after insertion, preventing back-out under vibration or thermal cycling. The latch holder fastening type provides an audible click when mated, giving the assembler or field tech a positive confirmation of full engagement without needing a secondary lock. The black colour is standard for the series and offers no special UV or chemical resistance beyond the PBT base material — treat it as a general-purpose interior-grade connector. Contacts are not included; you order the matching Micro Quadlok crimp socket terminals separately, sized for the wire gauge your harness calls for.
Termination and Mating — What You Need to Order Separately
This is a crimp-and-poke housing: the female socket terminals are inserted into the rear of the housing after crimping onto the wire. The TPA (Terminal Position Lock) is a secondary lock that slides into the housing face to capture the terminal lances — it must be in the open position during terminal insertion, then pushed closed to lock. The mating half is a Micro Quadlok plug header (male pin housing) with the same 2-position, single-row, 2.54mm pitch layout and latch holder. The latch on the socket housing engages the ramp on the plug housing; no tools are needed for mating or unmating. The Micro Quadlok series uses a specific socket terminal — verify the wire gauge range and order the terminals and any required crimp tooling separately.
