The main materials used in plug-in PCB terminal blocks include:
1. PCB terminal block housing: Also known as the plastic part, it is typically made of either flame-retardant and environmentally friendly PA66 plastic or non-flame-retardant and non-environmentally friendly plastic. High-end market customers usually require flame-retardant and environmentally friendly PA66 plastic, while low-end market customers may opt for non-flame-retardant and non-environmentally friendly plastic to reduce costs.
2. PCB terminal block hardware:
- Terminal block solder pins: Typically made of tin-plated brass, but some may use iron-plated tin for cost-cutting measures.
- Terminal block clamps: Usually made of nickel-plated copper, but some may use stainless steel to reduce costs.
- Terminal block squares: Generally made of nickel-plated copper, but some may use iron for cost-cutting measures.
- Terminal block screws: Typically made of zinc-plated steel for environmental protection.

Application examples of barrier terminal blocks in LED power
In LED power applications, HongYi barrier terminal blocks are often used to connect LED lamps and power supplies. The following are examples of barrier terminal in LED power applications:
Power input connection: LED power supplies usually need to be connected to a power cord to provide power supply. HongYi terminal blocks can be used to connect power cords and power input terminals, barrier terminal block connector ensuring stable power supply and safety.
Output connection: HongYi terminal blocks are also used to connect the output end of LED power supplies to LED lighting fixtures. LED lighting fixtures typically have multiple connection points, and pcb terminal blocks can provide a convenient and reliable way to connect the positive and negative poles of each LED light.
Multi channel connection: LED power supply may require connecting multiple LED fixtures simultaneously to meet the needs of large-area lighting. HongYi terminal block provides multiple connection functions, which can connect the power lines of multiple LED lamps to the corresponding terminal positions, terminal block 3 pole simplifying the circuit wiring and connection process.
The design of 3 pole terminal block can ensure stable electrical connections and signal transmission, improving the reliability and performance of LED power systems. For the selection of metal materials, common hardware parts usually use highly conductive and corrosion-resistant metals, such as copper or tin plated copper. pcb barrier terminal block can provide good electrical connections and durability, making them suitable for LED power supply applications. At the same time, under special requirements, other suitable gold materials can also be selected according to specific needs.
