Product Description

Shenzhen Jiayunkang Technology Co., Ltd. specializes in high-performance connectivity solutions built for demanding environments. Our range of 2-wire, 2/3/4/5-Pin Automotive Connectors is engineered to meet the rigorous standards of the modern automotive industry. These connectors serve as the fundamental interface for a wide array of electrical systems within a vehicle, providing a secure, vibration-resistant, and environmentally sealed connection for both power transmission and signal communication.

This versatile series allows for flexible configuration, from simple 2-wire, 2-pin setups for basic functions to more complex 5-pin designs that can handle multiple circuits within a single, compact housing. Designed with precision and durability as the top priorities, these connectors ensure that electrical systems remain operational despite constant exposure to temperature fluctuations, moisture, road salts, and mechanical stress. They are the ideal solution for creating robust, maintenance-free wiring harnesses in cars, trucks, motorcycles, and other mobile machinery.

Product Features

Multi-Pin Configuration: Available in 2, 3, 4, and 5-pin options, providing design flexibility for simple or complex circuits, including power, ground, and sensor signal lines.

Advanced Sealing Technology: Integrated silicone rubber seals on both the housing and individual terminals achieve a high IP67 or IP68 rating, guaranteeing complete protection against water, dust, and humidity ingress.

High-Temperature Resilience: Constructed from PA66 or PBT thermoplastic materials with a high UL94 V-0 flame-retardant rating, ensuring stable performance in under-hood and other high-temperature environments.

Secure CPA and TPA Systems: Features a Connector Position Assurance (CPA) latch to prevent accidental unmating and a Terminal Position Assurance (TPA) lock to ensure pins remain fully seated and secure within the housing.

Gold-Plated Brass Terminals: Precision-machined brass contacts with selective gold plating over a nickel base ensure low contact resistance, excellent corrosion resistance, and superior electrical conductivity.

Acid and Fuel Resistance: The housing material is engineered to resist degradation from common automotive fluids such as oil, gasoline, and cleaning agents.

Product Advantages

Enhanced Vehicle Reliability and Safety: By providing a sealed and vibration-proof connection, these connectors directly contribute to the long-term reliability of critical vehicle systems, reducing the risk of electrical failures and enhancing overall safety.

Streamlined Assembly and Service: The plug-and-play design, along with audible click locking, significantly speeds up the vehicle assembly line process and simplifies field repairs and component replacements, saving time and labor costs.

Long-Term Durability and Cost Savings: The combination of high-quality materials, superior sealing, and corrosion-resistant contacts extends the product lifecycle far beyond Standard Connectors, minimizing warranty claims and reducing the total cost of ownership.

Optimized Electrical Performance: Stable contact pressure and high-quality plating minimize voltage drop and signal interference, ensuring consistent performance for sensitive electronics like sensors and control modules.

Design Versatility: The availability of multiple pin counts and the ability to mix power and signal circuits in one connector offer engineers greater flexibility in designing and routing vehicle wiring harnesses.

Application Fields

These automotive connectors are essential components in a wide range of vehicle systems:

Engine and Powertrain Management: Connecting sensors (e.g., oxygen, crankshaft, camshaft), solenoids, and ignition systems.

Body Control and Comfort Systems: For power windows, door locks, mirror adjustments, and seat control modules.

Lighting Systems: Headlights, tail lights, fog lights, and interior LED lighting connections.

Sensor and Actuator Networks: Throughout the chassis, including ABS wheel speed sensors, parking sensors, and throttle control actuators.

Infotainment and Dashboard Electronics: Providing power and signal links for displays, audio systems, and control units.

New Energy Vehicles (NEVs): Used in battery management systems (BMS), low-voltage control units, and charging port accessories.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the 2-wire, 2-pin and the 2-wire, 3-pin versions?
A: A 2-wire, 2-pin connector is typically used for a simple on/off circuit. A 2-wire, 3-pin version often includes an additional pin for a feedback signal or a switched ground, allowing for more complex control and monitoring within a similarly sized housing.

Q2: Are these connectors compatible with standard automotive wiring tools?
A: Yes. Our connectors are designed to be used with standard industry crimping tools for the terminals and seals, facilitating easy integration into existing manufacturing and repair processes.

Q3: What is the operating temperature range for this connector series?
A: These connectors are designed to perform reliably in a wide temperature range, typically from -40°C to +125°C, covering the vast majority of automotive application requirements.

Q4: Can I get custom-colored housings for my specific application?
A: Absolutely. We offer customization services, including housing color coding, which is beneficial for circuit identification, error-proofing during assembly, and streamlined maintenance.
