The TE Connectivity 1445957-5 is a single-position, non-gendered housing from the Power Series 15/30/45 family. The red polycarbonate insulation gives visual distinction on the harness, and the spring retention fastening holds the mating halves together without a secondary latch or screw. This series is used for power distribution in industrial equipment, battery interconnects, and heavy-duty harnesses where individual circuits need to be broken out or serviced independently. The stackable feature lets you gang multiple 1-position housings side-by-side to build multi-circuit assemblies without a multi-position mold — useful when you need a custom position count or want to replace a single circuit without disturbing the whole connector.
Because this is a non-gendered housing, it mates with another 1445957-5 housing of the same series — there is no male/female distinction at the housing level. The actual gender comes from the crimp contacts you install. The spring retention provides the mating force; you'll feel a positive click when the two housings engage fully. Disengagement requires pulling the housings apart against the spring tension — no tool needed. The Power Series 15/30/45 uses specific crimp terminals — check the series datasheet for the exact contact part numbers and the recommended wire gauge range.
