Wire To Board Crimp Style Connectors

QA2009-A2019: 2.00mm Pitch Wire to Board Crimp Style Connectors

The QA2009-A2019 series connectors are specifically designed for automotive LED lighting modules, offering core advantages in connection stability and adaptability to harsh operating conditions. The series integrates a double-latch secondary locking mechanism that ensures secure mating through initial positioning and precise secondary engagement. This design effectively eliminates the risk of terminal loosening and guarantees continuous electrical connection.

An integrated locking-body protection structure prevents foreign object intrusion, deformation, and accidental unlocking, thereby extending service life. The terminals adopt a four-sided fully enclosed structure with a symmetrical double-sided contact design, ensuring precise mating and efficient conductivity. Both the board-side and wire-side connectors feature built-in interlocking structures and have passed automotive-grade vibration tests.

The wide operating temperature range of −40 °C to +125 °C enables the connectors to withstand continuous high- and low-temperature environments typical of LED headlight applications, making them suitable for various automotive lighting scenarios.

The QA2009-A2019 series connectors are developed for automotive LED lighting modules and are suitable for a full range of headlight assemblies. They are optimized for harsh operating conditions such as high temperature, vibration, and limited installation space, providing high-reliability connection assurance throughout the entire life cycle of the lighting system.

In terms of operating condition adaptability, the product features a wide temperature range of −40 °C to +125 °C and is resistant to high- and low-temperature aging and embrittlement. Multiple anti-loosening structures enable the connectors to pass automotive vibration fatigue tests, preventing terminal loosening and poor contact while ensuring stable power supply and signal transmission.

Regarding electrical performance, the terminals employ a double-sided contact design with a contact resistance of ≤10 mΩ. This design resists current fluctuations and prevents abnormal lighting behavior. The integrated protective structure provides dustproof, moisture-proof, and short-circuit protection, meeting sealed installation requirements. In addition, the compact design adapts to the limited space of vehicle headlight modules, is compatible with various high-power LED light sources, and is suitable for both passenger and commercial vehicle headlight assemblies. The product meets the high reliability, durability, and safety requirements of the automotive electronics industry.

JKUN connectors utilize a dual-branch parallel synchronous production process in compliance with IATF 16949 standards, establishing closed-loop control from raw materials to final delivery.

In the copper-strip branch, terminals are manufactured through precision stamping and electroplating processes. In parallel, the injection-molding branch produces plastic housings and related components. After the two branches converge, the products undergo automated assembly, CCD 100% inspection, tape packaging, and final inspection.

Finished products are stored in a constant-temperature warehouse and managed on a first-in, first-out (FIFO) basis, ensuring accurate order fulfillment, high efficiency, consistent quality, and full data traceability throughout the process.

JKUN adopts standardized packaging methods. Products are neatly packed into appropriately sized cartons and then secured on pallets for convenient forklift handling.

Products should be stored in their original packaging in a clean, dry warehouse environment. It is recommended to avoid direct light exposure and to maintain minimal temperature and humidity fluctuations. External pressure or damage to the packaging should be avoided.

Transportation options are flexible and include full truckload road transport, international express services (UPS, TNT, FedEx, EMS, DHL), air freight, and sea freight, selectable according to order requirements and logistics coverage.

During transportation, contact with sharp objects and severe impacts should be avoided to prevent damage to the packaging, which may affect the product. Under normal transportation and handling conditions, the product poses no undue health hazards; however, safe loading and unloading practices should be observed, and careless disposal of packaging materials should be avoided.
