The wide temperature range and vibration resistance withstand demanding automotive conditions. The protective cover prevents solder splashing, and the reflow soldering process is fully compatible with vehicle SMT production lines, improving assembly efficiency.
♦ Industrial Automation High-Power Equipment: Designed for servo drives and industrial robot joint drive boards. The high-power transmission capability supports industrial loads, while reflow soldering eliminates the efficiency bottleneck of traditional wave soldering. The protective cover blocks workshop dust, and high vibration resistance supports high-frequency equipment operation.
♦ Outdoor Energy Storage and Portable Power Supplies: Suitable for portable outdoor power stations and photovoltaic micro-inverters. The right-angle configuration optimizes space for thinner and lighter equipment. The ultra-wide temperature range withstands outdoor temperature variations, and high voltage resistance enhances circuit safety redundancy. The connector is also compatible with mainstream photovoltaic supply chain interfaces.
♦ Rail Transit On-Board Control Modules: Suitable for subway door control units and rail vehicle air-conditioning control boards. The ultra-wide temperature range withstands tunnel temperature fluctuations, and high vibration resistance tolerates continuous train vibration. The protective cover blocks dust ingress, ensuring long-term stable module operation.
♦ Communication Base Station Power Distribution Units: Compatible with base station rectifier modules and 5G base station RRUs, providing high-power multi-circuit power distribution. The connector offers tolerance to base station temperature variations, protection against dust and moisture, and reflow soldering technology that improves assembly efficiency.
Production Site
The core production base operates with full-process automation. The injection-molding workshop ensures dimensional accuracy of LCP housings and protective covers. The stamping workshop processes high-conductivity brass terminals. The assembly workshop deploys automated production lines integrated with testing equipment, enabling combined terminal crimping, component assembly, and initial inspection, thereby strengthening overall quality control.
Package & Transportation
Industry-standard packaging is adopted. Products are sorted, packed, and secured on standard pallets suitable for forklift handling. Storage requires keeping the original factory packaging and placing products in a clean, dry warehouse with stable temperature and humidity, avoiding external pressure or deformation.
Transportation options include road transport, international express delivery, air freight, and sea freight. During transportation, protection against sharp objects and severe impacts is ensured, and proper recycling of packaging materials is emphasized.
Authoritative Certification & Independent Patents: Dual Technical Assurance
The product is certified under authoritative management systems including IATF 16949, ISO 9001, and ISO 14001, covering production, management, and service processes. The company also holds multiple utility model patents focused on connector structure optimization, reflow soldering process innovation, and precision assembly technology. These technologies establish a strong technical barrier and provide core support for product compliance and market competitiveness.
