Terminal Blocks - Wire to Board

Terminal blocks – wire to board are devices used to connect wires and cables with printed circuit boards (pCBs). They are generally used in applications where terminal blocks are more suited than other alternatives such as ribbon cables. Generally, they are used in electronic equipment such as industrial automation, industrial process control, process instrumentation, automotive, measuring and medical equipment.

Terminal blocks – wire to board consist of two parts, a male (plug) and a female (receptacle) connector. The male connector mates with the printed circuit board and the female connector mates with the wire. Each connection is soldered safely and securely in place, guaranteeing no accidental connectivity. Depending on the application, the terminal blocks will vary in voltage, current, and insulation. There are two different types of terminal blocks: screw type and solder type.

Screw Type

Screw type terminal blocks are the most common type of terminal blocks used. These connection blocks are used for low current, low voltage applications, such as lighting and control wiring. The screw type connection is designed so that the wire is firmly held in place when a screw is tightened. These screw connections provide superior electrical connection and ensures that that the connection is secure.

Solder Type

Solder type terminal blocks are used for higher voltage, higher current applications, such as AC power. They provide a more secure connection than screw type connections as the solder bonds the wire to the block more securely. This means that the connection is less likely to break down due to shock or vibration. It is also easier to connect larger wires to the solder terminal blocks.

Working Principle

To use terminal blocks – wire to board, a wire or cable is inserted into the female connector of the terminal block, which is connected to the circuit board. The male connectors of the block are then soldered securely in place on the circuit board. The wire can then be connected to the male connector with either a screw or a soldering iron, depending on the type of terminal block being used. This ensures that the connection is secure and reliable, providing a reliable electrical connection for electronic components.

Application Field

Terminal blocks – wire to board are commonly used in a variety of electronic applications. They are used in the industrial automation industry for connection of sensors, actuators, and other components. They are also used in process control, process instrumentation, and medical applications. In automotive applications, they are often used connecting wiring harnesses with the vehicle’s main electrical system. In medical applications, they are often used for patient monitoring systems or anesthesia delivery systems. They are also used in a variety of measuring instruments, such as flow meters, pressure transmitters, and temperature sensors.

Terminal blocks – wire to board are a versatile and reliable connections and are used in a variety of electronic applications. Their design ensures a secure and reliable connection while also providing an easy and convenient way to connect wires and cables to circuit boards.
