AI Technical Summary
Traditional RJ connectors have a single interface design that cannot meet the needs of multi-interface connections, poor grounding settings lead to weak anti-interference capabilities, and the manufacturing process is complex and prone to poor contact problems.
The device uses SMT-type RJ connectors, with the connector interfaces and grounding solder pins arranged in parallel. The terminal assembly is formed in one mold, and the terminals and plastic blocks are integrally formed. Electrical connection and automated soldering are achieved through SMT technology, which enhances the grounding path and signal stability.
It meets the requirements for multi-interface connections, reduces PCB layout space, improves anti-static discharge and electromagnetic interference capabilities, simplifies the manufacturing process, enhances signal stability and overall connector stability, and is suitable for high-density equipment applications.
