H15EDGKDH-3.5 Pcb terminal block connector

H15EDGKDH-3.5 PCB Pluggable Terminal Block Connector

The H15EDGKDH-3.5 is a highly efficient, double-row screwless terminal block designed for high-density PCB connections. It perfectly combines the convenience of a pluggable header with the reliability of a spring-cage connection.

Core Structure & Working Principle

• Insulated Shell: Made of flame-retardant PC or PA66 nylon material (UL94V-0). Common colors include white, black, and blue.
• Metal Terminal: The core conductive component, typically made of phosphor bronze or brass with a tin-plated surface. It features a high-elasticity spring clamping structure.
• Operation Hole / Push Button: A small hole next to each wiring position used to insert a dedicated release tool (or screwdriver) to press down the internal spring plate and release the wire.
• Guide Keys & Buckles: Ensures correct alignment and secure locking with PCB pin headers (Fool-proof design).

Wiring Workflow & Precautions

Wiring Process:

• Inserting wires: Insert solid wires (stripped 8-9mm) or multi-stranded wires with cold-pressed ferrules directly into the hole until you hear a "click" or feel significant resistance. The internal spring firmly clamps the wire.
• Pulling out wires: Insert the dedicated tool into the operating hole, press down to open the spring plate, and easily pull the wire out.

Crucial Precautions:

• Use Correct Wire Types: Strongly recommended to use solid wires or multi-stranded wires with tubular pre-insulated ferrules. Inserting untreated flexible cords directly is the main cause of poor contact.
• Proper Tool Use: Use the matching tool for disassembly. Do not pry hard with sharp objects to avoid damaging the spring.
• Do Not Exceed Specs: Strictly prohibited from connecting loads that exceed the rated current and voltage.

Main Advantages

• Extremely High Wiring Efficiency: Eliminates the need for tightening screws, increasing wiring speed by over 70%. Ideal for large-scale production or rapid on-site maintenance.
• Reliable Anti-Vibration: Constant spring pressure prevents loosening in vibrating environments, outperforming standard screw terminals.
• High Density (Double Row): The dual-row 3.5mm pitch design provides a massive number of connection points in a limited space, perfect for LED displays and controllers.
• Fool-proof Design: Plugs and headers feature guide keys to prevent reverse insertion.
