The TE Connectivity 917697-1 is a 13-circuit plug housing from the Signal Double Lock series, built for free-hanging wire-to-wire interconnects where the harness needs a positive lock and a compact single-row layout. The 2.50 mm pitch keeps the connector narrow enough for tight bundle routing while leaving room for the locking ramp — a detail that matters when the harness runs through a vehicle or machine panel and vibration could work a plain friction latch loose.
The One Thing That Trips Up a BOM
This is a housing only — contacts are not included. The listing carries a clear note: Contacts Not Included. You need to order the matching TE Signal Double Lock female crimp terminals separately, sized for your wire gauge. Ordering just the housing and expecting a finished connector is the most common sourcing mistake on this line.
Locking Ramp Retention and Free-Hanging Fit
The locking ramp fastening type gives an audible click when the plug fully seats into the mating receptacle — a tactile confirmation that the pair is locked against pull-out. For a free-hanging (in-line) connector, that ramp is the primary retention; there is no secondary locking mechanism on this housing, so the ramp engagement is what keeps the harness mated under cable strain or vibration. The single-row layout with 13 positions means the connector body stays narrow, which helps when routing the harness through a grommet or along a frame rail.
