3. Electrical Characteristics

Completely adapted to the mainstream on-board low-voltage power supply environment of passenger cars and commercial vehicles, the product is equipped with a standard nominal voltage architecture of 12V, which perfectly matches the daily conventional power supply and signal transmission needs of automotive body electrical systems. Cooperated with high-precision professional receptacle contact accessories, the internal conductive structure has low contact resistance, stable conductivity and strong continuous conduction capacity. It can steadily support the power supply of automotive small sensors, interior electrical accessories, light signal circuits and body auxiliary electrical modules. The optimized elastic contact structure can resist long-term bumpy vibration and daily temperature cycle changes of the vehicle, effectively avoid poor virtual connection, signal interruption and circuit power failure, and ensure the continuous and safe operation of automotive low-voltage electrical circuits.

4. Body Features

The overall body of the connector is made of high-quality raw materials and integrally injection-molded. The primary product color is uniform industrial black, with smooth and burr-free surface, no deformation, no color difference and no mixed impurities. The professional 180° cable exit angle design is adopted, which is convenient for straight and neat wiring harness layout, saves the internal installation space of the vehicle body, and is not easy to cause wire winding and extrusion. The overall structure is solid and rigid, with strong compression resistance, impact resistance and aging resistance, and can adapt to long-term complex working conditions inside and outside the vehicle body. This model has no extra connector keying code, the structure is simplified and practical, the assembly threshold is low, and the on-site wiring operation is more convenient and efficient.

5. Contact Features

Matched with high-precision receptacle professional contacts, the standard contact size is 0.64mm, and the precise mating tab width is also controlled at 0.64mm, which perfectly fits the matching male terminal plugging specifications in the industry. The contact accessories are made of high-conductivity special conductive materials, with excellent oxidation resistance, corrosion resistance and thermal stability, and can maintain stable contact performance in humid, dusty and slightly oily vehicle environments. The built-in elastic clamping structure has uniform and lasting clamping force, which can firmly lock the butted terminals, effectively prevent terminal retreat, loosening and falling off caused by vehicle vibration, and ensure long-term stable electrical connection without failure.

6. Dimensions

Produced by high-precision automotive professional molds, the overall dimensional tolerance is strictly controlled to ensure high matching accuracy. The standard connector height is 27.2mm, the product overall length is 13.7mm, and the product overall width is 14.9mm. The internal core centerline pitch is standardized to 2.54mm, which is fully compatible with the assembly fixtures, wiring harness molds and matching tools of the same series of automotive connectors on the market. The overall size is compact and regular, which is convenient for installation in narrow gaps of vehicle body parts. All dimensions are fully interchangeable with the original 1-936527-2 connector, no need to replace production tooling, directly plug and play for replacement.

7. Usage Conditions

Relying on excellent raw material performance and fully sealable integrated waterproof and dustproof structure, the product can adapt to various conventional and harsh working conditions of automotive interior and exterior wiring. It can resist daily dust accumulation, humid air erosion, light rain splashing and slight oil contamination in the vehicle, and will not have poor contact, shell aging and brittle cracking due to environmental factors. It is suitable for long-term stable wiring use in closed interior of vehicle body, peripheral wiring of interior electrical appliances and non-severe exposed positions of vehicle body, with strong environmental adaptability and long service life.

10. Installation Notes

Before assembly, check whether the internal sealing ring is intact and whether the receptacle contacts are elastic and smooth to ensure no defective parts. Align the polarizing rib for accurate mating alignment during operation to avoid wrong insertion and reverse insertion. Push the connector firmly until the clean body locking structure is completely clamped to confirm that the assembly is in place. Do not pull the wiring harness violently or bend the wire body sharply at the connector root after installation. It is forbidden to use it in overload circuits exceeding the standard 12V voltage to avoid electrical safety hazards. Regularly check the tightness of the connector during later use to ensure stable connection.
