Terminal Blocks - Headers, Plugs and Sockets

1858811 terminal blocks are one of the most common types of terminal blocks used in electrical wiring. A terminal block is a connector typically made of metal or plastic that allows two or more wires or other conductors to be connected to each other. It is commonly used for connecting electrical devices such as switches or motors to a circuit board.

Terminal blocks are available in various shapes and sizes to accommodate different types of wire sizes and types. There are also many different types of insulators that can be used depending on the application. The most common type of insulator is usually made of rubber-like material or plastic.

Types of Terminal Blocks

There are two main types of terminal blocks commonly used in electrical wiring: headers and plugs/sockets. Headers, also known as split-type terminal blocks, are typically used when the wires need to be divided or grouped. They are often used in applications where a circuit board needs to be distributed or multiple wires need to be routed in different directions.

Plugs and sockets, also referred to as pluggable terminal blocks, are used when the wires need to be connected to other devices such as switches or motors. These types of terminal blocks are designed to be inserted into a socket and then connected to other devices. The socket can come in different shapes and sizes depending on the application.

1858811 Application and Working Principle

The 1858811 terminal block is a headers type terminal block commonly used in industrial applications. It is designed to facilitate quick and easy assembly and installation. The terminal block features an improved pressure seal and provides fast, reliable connection of both 14 AWG and 12 AWG wires. It is also designed to be resistant to corrosion and vibration.

The 1858811 terminal block consists of three main components: a base, a plug, and a crimping shell. The base is used to mount the terminal block to a DIN rail or other mounting surface. The base also provides a secure base for the internal components. The plug is used to connect the wires to the terminal block, and the crimping shell provides a secure, reliable connection. The crimping shell contains a screw and two contact pins which provide the electrical connection.

Once the wires are connected to the terminal block, the plug is inserted into the base and the screw is then tightened to ensure a secure connection. The crimping shell also provides insulation between the terminal block and the wires. The crimped connection provides additional strength and flexibility to the terminals and helps to keep them from accidental disconnection.
