Single-Circuit Power Timer Housing for Field Repair
The TE Connectivity 282533-2 is a 1-position Standard Power Timer receptacle housing — a single-circuit shell designed for adding or replacing one power or signal line in an existing harness. The black PA66 (Nylon) body carries a Terminal Position Lock (TPA) feature, a secondary retainer that locks the crimp contact in place so it cannot back out under vibration before the connector is fully mated.
Locking Ramp and TPA — Field Reliability Details
The Terminal Position Lock (TPA) is a separate plastic insert that slides into the housing after the crimp terminal is loaded. It blocks the terminal's lance from deflecting, so a partially seated contact cannot pass the pull-test. For a field-service technician rebuilding a harness one contact at a time, the TPA is the difference between a connection that holds and one that backs out on the first thermal cycle.
The polyamide (Nylon) insulation is a standard choice for automotive and industrial connector bodies — it absorbs some moisture over time, but the temperature rating stays within the dry-use envelope.
