1. Product Type Features

This item is a professional IP67 waterproof female automotive connector developed for vehicle outdoor and under-hood electrical systems. TE internal part number is 144473-4 with official description: CET 2 POS ASSY JPT. Designed as a round-shaped female socket connector, it adopts fully sealed waterproof structure to adapt to harsh outdoor vehicle working conditions. The overall design is anti-dust, anti-moisture and anti-corrosion, ideal for long-term exposed installation in automotive exterior parts. It is a direct replacement compatible with original 144473-4 harness matching parts, suitable for mass OEM assembly and aftermarket repair replacement.

2. Configuration Features

Standard fixed 2-pin integrated cavity layout ensures independent circuit transmission without signal crosstalk or short-circuit risk. The round housing structure provides uniform locking force during mating, ensuring smooth plug-in and pull-out operation. Optimized inner cavity structure effectively prevents misalignment, wrong insertion and poor connection. Modular unified structure supports batch automatic harness production and manual on-site maintenance, greatly improving production efficiency and reducing assembly error rate.

3. Electrical Characteristics

Rated working current reaches 6A and rated working voltage is12V, fully matching standard automotive low-voltage DC electrical systems. Adopting high conductivity brass contact material, the terminal features low contact resistance, stable current transmission and excellent anti-aging electrical performance. The internal elastic contact structure ensures continuous and reliable electrical connection even under continuous vehicle vibration, effectively avoiding intermittent circuit failure and signal loss.

4. Body Features

The connector housing is made of high-strength engineering plastic material with strong toughness, impact resistance and deformation resistance. The outer shell surface is precisely processed with waterproof groove and buckle structure, tight fit after docking, not easy to loose or fall off during long driving. The overall round shape is compact and space-saving, easy to arrange in narrow vehicle gaps. The shell is resistant to engine oil, dust, ultraviolet rays and temperature aging, maintaining stable physical performance throughout the whole service life.

5. Contact Features

High-quality brass terminals ensure excellent electrical conductivity and oxidation resistance. The female contact design provides stable clamping force for male terminals, ensuring firm locking and reliable contact. The surface of terminals is treated with anti-rust and anti-corrosion process, suitable for humid and dusty outdoor environments. The structural design ensures repeated plugging and unplugging without deformation, maintaining stable electrical performance for long-term vehicle operation.

6. Dimensions

Standard industry unified outer diameter and interface size, fully compatible with original 144473-4 matching plugs and harness accessories. Precision mold production ensures uniform dimensional tolerance, smooth assembly and perfect interchangeability. No need to change existing harness molds or assembly fixtures, directly replaceable for old connectors in automotive wiring harness systems.

7. Usage Conditions

With professional IP67 waterproof rating, the connector is fully dust-tight and water-resistant, suitable for underbody, wheel area, exterior lamp and engine peripheral wiring. It adapts to all-weather outdoor working environments, resisting rain washing, splashing water, mud, dust and humidity erosion. Stable performance in seasonal temperature changes, not easy to aging, brittle or fail under long-term complex outdoor vehicle conditions.
