Read on to find out more about block connectors and their uses.

What are terminal block connectors?

A terminal block connector (also known as a connector terminal block) is a modular block that’s usually made from plastic or some other type of insulating material. The block acts as a connector that secures two or more wires together. It does this by joining multiple outgoing wires to a single incoming wire.

The terminal block can be a simple or more complex structure, depending on the amount of wiring that needs to be connected. There are different layouts and setups available, but each terminal connects to just a single wire.

The block itself consists of a clamp or screws to hold the wires in place and a conducting strip. This strip is the current-carrying part of the block that enables the electricity to run through the wires that are being connected, continuing the circuit.

What are terminal block connectors used for?

Terminal block connectors are useful in situations that require multiple wires to be connected safely. Without a block connector, connecting the wires properly can be difficult and dangerous.

The clamp inside holds the wires in place, tidying them away and keeping them secure. This is the reason why one of the most common applications for terminal block connectors is in industrial settings, where more than one connection is needed across power, signal applications, automation and controls. Some common applications include factories and warehouses where a lot of wiring must be connected carefully.

What are the different types of terminal block connectors?

While they all perform the same function, there are different variations on the terminal connectors that are available. These different models are designed to meet the specific needs of the job at hand. Below is an overview of some of the types of block connectors you will find at RS:

• DIN terminal blocks DIN terminal blocks are available in single, dual and triple level. Due to their simple functionality, they are some of the most common terminal block connectors on the market. Each of these terminals can be easily clipped onto the rail and mounted into electrical paneling, securing them in place and making the work area safe.
• Double-level terminal blocks These provide added connectivity for your wiring. While they have a double function shaft, they remain compact, making them a neat addition to an industrial setting.
• Feed-through terminal blocks Feed-through terminal blocks have two terminal points and a neat design. In addition, they offer flexible bridging options, making it easier to connect wiring.
