Terminal Blocks - Wire to Board

Wire to board (OTST7200151) terminal blocks are common in industry for electrical interconnectivity. Basically, the terminal block is a device that essentially functions as a bridge between wires connecting to a board. It can accommodate different sizes of wire and provide different protection options, depending upon the application. It also allows for quick and easy connection and disconnection of wire strands with minimal effort.

Application Field

Wire to board (OTST7200151) terminal blocks are used in a variety of applications, including power distribution, lighting control, automation, switchgear, audio systems, and solar electric power systems. In industry, they are often used to create a connection skeleton between a main power supply and a number of secondary loads. They can also be used in a more decentralized application to terminate multiple wire runs to a control panel.

In addition, these terminals can be used for testing and troubleshooting, either to connect components temporarily for testing or to create a permanent connection when repairs are completed. With either application, the terminals allow for a quick and secure connection, with minimal disruption to the test and troubleshooting process.

Working Principle

Wire to board (OTST7200151) terminal blocks are designed to provide a secure connection between two points in an electrical circuit. Generally, the terminal block consists of an insulating block or plate that holds the contact elements. The contacts are then soldered to the block, which is then secured to the board. For convenience, the terminals are normally provided with mounting holes for fixing screws and clamps. The contact elements can accommodate different sizes of wires, depending on the application.

When wiring to the terminal blocks, each power lead is inserted into the corresponding contact element. Each wire is then secured with the screws or clamps that are provided with the terminals. The clamps or screws grip the wire firmly, creating an electrical and physical connection between the two points in the circuit. Finally, the wire is soldered and insulated with shrink or heat-shrink tubing, which creates a waterproof seal.

Wire to board (OTST7200151) terminal blocks are a convenient and effective method of connecting two points in an electrical circuit, whether for testing, troubleshooting or installing a permanent electrical connection. They provide secure and reliable connections while eliminating the need for complex wiring schemes. Furthermore, with different contact elements to accommodate different sizes of wires, these terminals provide an efficient and cost-effective way to connect and disconnect a circuit with minimal effort.
