Terminal blocks, or terminal strips, act as quick-connect or disconnect components in an electrical circuit. They can be used for a variety of applications such as interconnecting wires and/or connecting different types of components, such as resistors, capacitors, switches, and transformers. Wire-to-board terminal blocks, sometimes referred to as barrier strips, provide an interface between a single wire and a PCB, allowing the system designer to easily add or remove a connection.

The design of a wire-to-board terminal block usually consists of a molded insulating base and a set of spring-loaded contacts that feature a barb-type design, permitting tight connection of several wires or cables to the block. The contacts are usually made from phosphor bronze or high-temperature metals, which offer excellent electrical performance, and are available in a wide range of sizes to suit a variety of wiring.

The model 1706640 terminal block is specifically designed for use in wire-to-board applications. It is a compact terminal block, with a 20A current rating, making it suitable for use in a wide range of low voltage applications, such as power supplies, automotive electronics, and home appliance products. The design of the terminal block makes it suitable for use in a variety of configurations, such as daisy-chain, vertical, and side-to-side, depending on the current rating requirements.

The design of the 1706640 terminal block features double-sided finger and palm-clamp connection technology, meaning that the contact elements are made from both the top and bottom sides of the terminal. This ensures good and reliable contact between the traces on the PCB and the wires or cables connected to the terminal. The contact elements are angled and sized to ensure good contact with a wide variety of wire types, ensuring consistent electrical performance. The barb-type design of the contact elements also ensures that connection of several wires or cables is secure and repeatable.

The 1706640 terminal block features an insulated base, made from UL flame retardant plastic, offering a high level of safety. The insulation is also highly resistant to moisture, preventing problems caused by condensation in the enclosure. The terminals are also provided with locking screws to prevent inadvertent loosening of the connection, which could lead to failure or other safety hazards.

In summary, the 1706640 terminal block is a robust and reliable wire-to-board connection system that is suitable for use in a variety of electronic applications. The double-sided finger and palm-clamp contact design provides a secure and repeatable connection between the terminals and the PCB, ensuring good electrical performance and a long service life. The insulation material used in the base of the terminal block is UL flame retardant and highly resistant to moisture, which ensures a high level of safety. The locking screws also provide additional protection against inadvertent loosening or other problems, making this terminal block an ideal choice for reliable wire-to-board applications.
