Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, also known as headers, plugs and sockets, are electrical devices that exist to provide a stable and reliable strain relief for electrical wires. They have existed since the early days of industrial electrical wiring, and they continue to be used in modern industrial control and process control systems. Terminal blocks are available in a variety of configurations and can accommodate a range of wire sizes. The 1771140000 terminal block, also known as a 2-7 Series terminal block, is a versatile and popular terminal block for industrial and process control applications.

Terminal Block Construction

The 1771140000 terminal block is a crimp-style terminal block, designed to provide a reliable and secure connection for wires. Its construction consists of a molded plastic housing with the terminal block’s electrical contacts embedded inside. The block is cut along one side to create access to the contact terminals. Each of the contact terminals is covered with an insulation sleeve to protect against accidental contact. A pair of crimp terminals are used to secure a wire into the contact terminal. The two sides of the block are then screwed together, enclosing and securing the wire.

Applications

The 1771140000 terminal block is primarily used for wiring in industrial and process control systems. It is common for these blocks to be used in control panels, cabinets and enclosures. They can also be used to create electrical junctions, allowing for multiple wires to be connected together. The use of removable terminal blocks allows for easy system maintenance as wires can be easily removed or added without disturbing existing wiring.

Installation

Installing the 1771140000 terminal block is a relatively simple process. The wiring can be either soldered or crimped to the block’s contact terminals. The wiring must be stripped correctly, and the insulation sleeve must be present to prevent accidental contact. Once the wires are securely affixed to the block, the two halves must be tightened together using a screwdriver or hex key.

Types

The 1771140000 terminal block is available in a variety of configurations to meet different wiring requirements. They can accommodate wire sizes from 0.14 to 2.5mm (0.006–0.098 inches). The two halves of the block can be connected using standard screws or quick-connecting captive screws, depending on the type.

Working Principle

The 1771140000 terminal block creates an electrical connection between two wires by using a combination of electrical contact and mechanical strain relief. The electrical contact is created by the conductive contacts in the block, which provide an electrical pathway between the two wires. The mechanical strain relief is provided by the terminal block itself, which acts as an anchor for the wires, preventing movement or twisting of the wires.

Conclusion

The 1771140000 terminal block is an incredibly versatile and powerful terminal block used in industrial and process control systems. Its modular design, allowing for easy installation and wiring, makes it perfect for a wide range of applications. It provides a reliable and secure connection for electrical wires, and its solid construction ensures durability and reliability.
