What This 2-Position Plug Housing Does
The TE Connectivity 177898-1 is a 2-circuit plug housing from the Power Double Lock series, designed as a free-hanging inline connector for wire-to-wire or wire-to-board power distribution. The 3.96mm pitch matches the standard Power Double Lock footprint, giving enough spacing between circuits for the rated voltage without crowding the harness. Contacts are not included — you order the matching female socket crimp terminals separately.
Mating and Termination — What It Needs to Work
This is the plug half; it mates with the corresponding Power Double Lock receptacle header (panel-mount or board-mount). The latch lock provides positive retention — you hear it click when fully seated, which matters in a vibration path like a vehicle harness. Termination is crimp-style: you strip, crimp the socket terminal onto the wire, and insert it into the housing cavity until the retention lance locks. No contacts are included with this housing — the BOM line needs a separate terminal order code.
