Terminal Blocks - Wire to BoardTerminal blocks, wire-to-board connectors, are a type of electrical connector used to attach wires to printed circuit boards. They are often used in the power, electronic, instrumentation, telecom, lab automation and medical industries. They enable compact and cost effective means to join and disconnect wires. Terminal blocks are generally classified according to the type of connection, material, and/or use. For example, terminal blocks may be classified types of versatile terminal blocks, application specific terminal blocks, special purpose terminal blocks, and active terminal blocks based on their intended use. Types of versatile terminal blocks include barrier strip terminal blocks, fuse terminal blocks, and ring tongue terminal blocks.The 2-1546074-3 Application Field and Working Principle of terminal blocks provide versatility and power to industries that need a reliable means of connecting wires to printed circuit boards. This type of terminal block is a barrier strip with wide metal spring fingers that allow for a secure connection. The springs are placed on the contacts and they exert tension on the connection. This type of terminal block is ideal for powering up circuits that need multiple runs of wire. The type of connection would be a spring finger or screw terminal.These terminal blocks also make use of jacks. Jacks are inserted into the terminal block and then are used to hold the wires in place. The metal coil spring fingers provide a secure connection between the wires and the terminal block. This type of terminal block can provide power for multiple circuits simultaneously.This type of terminal block also features multiple planes so that more wires can be connected in parallel. Each plane has different lines that go in different directions providing flexibility when connecting multiple wires. The planes can also be connected to each other with small screws or solder connections.The pieces of the 2-1546074-3 Application Field and Working Principle are made of heavy silicone plastic and aluminum. The spring fingers are made of chrome plated copper and the jacks are made of stainless steel. The plastic provides insulation and helps protect the terminal block from short circuiting and arcing. The aluminum is used to provide a strong connection between the wires and the printed circuit board and also helps to dissipate the heat when the circuit is operating.The screw terminal connectors are designed to provide a tight connection without the need for solder. The strong aluminum construction provides flexibility and durability. The mounting holes make it easy to connect and disconnect the components as needed. The terminal block is designed to withstand extreme temperatures and vibration.This type of terminal block is designed for high power applications and is ideal for use in industrial settings. It is reliable and durable and can be used for multiple circuit applications. It is easy to install and maintain and is a great value for the money. It is also one of the most reliable types of terminal blocks used in the industry.
