3. Electrical Characteristics

Designed specifically for automotive low-voltage power circuits, this connector supports a nominal voltage architecture of 12V, perfectly matching the mainstream 12V power supply system of passenger cars, light commercial vehicles and engineering machinery vehicles. The internal receptacle terminals adopt high-conductivity copper alloy material with excellent electrical conductivity, low contact resistance and stable current transmission performance, ensuring continuous and safe power output for automotive low-current electrical components. The insulating housing material provides strong voltage resistance and reliable insulation protection, effectively preventing electric leakage, short circuit and static electricity accumulation during long-term vehicle operation. All electrical performances comply with automotive low-voltage safety specifications, ensuring stable power supply for vehicle body power modules, small electrical accessories and conventional on-board electronic equipment without electrical failure risks.

4. Body Features

The entire connector housing is injection molded with high-quality professional PA engineering plastic material, featuring high toughness, strong compression resistance, impact resistance and outstanding anti-aging performance. The finished product adopts classic solid black as the primary color, with smooth surface, uniform texture, no deformation, no discoloration and no brittle cracking after long-term use in vehicle environment. The connector is designed with a 90° cable exit angle, which reasonably changes the wiring direction of the harness, saves limited installation space inside the vehicle body, avoids sharp bending and extrusion damage of wires, and optimizes overall wiring harness routing layout. The PA plastic housing has good oil resistance, dust resistance and corrosion resistance, resisting daily erosion of dust, oil mist and temperature alternation inside the car, maintaining stable structural performance and long service life all year round. The connector adopts neutral keying code design for convenient universal matching without complicated positioning restrictions.

5. Contact Features

Equipped with high-precision standard receptacle-type female contacts, the contact size is 6.35 mm, and the supporting mating tab width is also 6.35 mm, ensuring precise, tight and seamless docking with matching male terminals. The receptacle contacts have built-in elastic clamping structure with uniform and lasting clamping force, which can firmly lock the mating male terminals and effectively prevent poor contact, power failure or signal interruption caused by long-term vehicle bumping and vibration. The contact surface is precisely electroplated to enhance oxidation resistance and corrosion resistance, maintaining stable and efficient conductive performance in dusty and slightly humid vehicle working environments. The contact assembly is accurate and firm, not easy to retreat or loosen, ensuring long-term stable and reliable power transmission of automotive circuits.

6. Dimensions

Manufactured with high-precision automotive professional molds, all dimensional parameters strictly comply with original industry standards. The connector height is 18.7 mm, product length is 17.3 mm, and product width is 17.2 mm, featuring compact overall size and lightweight design, suitable for installation in narrow gaps of vehicle body, electrical boxes and peripheral equipment edges. The internal row-to-row spacing is standardized at 11.5 mm, ensuring smooth terminal insertion and stable assembly. The overall size is highly interchangeable with the original 1544352-1 connector, no need to replace assembly tooling and molds, directly plug-and-play for replacement, maintenance and batch harness production, effectively saving enterprise procurement and production costs.

7. Usage Conditions

This automotive wire plug connector has excellent environmental adaptability, supporting a wide professional operating temperature range from -40°C to 125°C. It can withstand extremely low-temperature freezing weather in cold northern regions without housing brittleness and contact failure, and also resist high-temperature heat radiation near vehicle engines in summer without aging and deformation. It is suitable for long-term stable work in conventional interior wiring, non-watertight peripheral electrical equipment connection and general chassis wiring environments. Even under the conditions of seasonal temperature changes, slight dust accumulation and conventional mechanical vibration, the connector can maintain stable connection performance, fully adapting to all-weather daily driving working conditions of various vehicles.
