Electrical Connectors and Fuse Holders

Designed to meet current transmission needs in power distribution systems and industrial control loops, this series of components integrates precision conductive terminals, insulating supports, and modular bases. The structure includes terminal blocks with metal inserts, transparent protective housings, and bases with complex snap-fit features, aiming to achieve secure cable connections, circuit protection, and signal switching. These components are commonly used in power distribution units for photovoltaic inverters, charging piles, and automation equipment.

The core of our manufacturing lies in the combination of high-precision mold development and multi-material molding processes. For black and white main body parts, we select engineering plastics with excellent heat resistance and flame retardancy (such as PBT, PA66) or thermosetting materials (DMC/BMC) to withstand harsh thermal shock environments. Transparent parts require high light transmittance without flow marks or bubbles. Processing challenges focus on controlling positioning accuracy during insert molding to prevent flash from affecting electrical contact, while ensuring dimensional consistency of thin-walled snap-fit structures to guarantee sealing and insertion/extraction forces meet standards after assembly.

Leveraging Jianda Electric's manufacturing expertise in low-voltage appliances, our factory is equipped with high-tonnage horizontal injection molding machines from Haitian and Engel, as well as specialized DMC thermosetting injection molding equipment. We support one-stop services from mold design to finished product assembly. The production site implements the IATF16949 quality management system, utilizing Zeiss coordinate measuring machines and industrial CT to monitor key mating dimensions, internal defects, and RoHS compliance throughout the process. This ensures delivered products meet the supply chain standards of major European and American electrical giants and the new energy industry.
