Hundreds of electrical tools and devices are used to increase efficiency and support the demands of the ever-changing industry.

Along with these, all devices also require efficiency in terms of its connection from one output to another especially its electrical components which is one of the major aspects of today’s devices.

One of the most commonly used electro-mechanical device that is used to join electrical terminations and the electrical circuit is the Electrical Connector.

Today we’re going to talk about the terminal blocks from these parts:

Terminal Block is used as a temporary connector for portable devices with easy assembly and removal functions or as a permanent connector of an electrical joint between two or more wires or devices.

One of its types is the Terminal Strips, also known as terminal boards or terminal blocks.

What is a Terminal Strip?

A Terminal Strip (also called as terminal boards/ block) is a simple type of an electrical connector which provides a convenient and safer means of connecting various electrical wires without cutting through the insulation to physical join both ends using insulation tapes (electrical tapes) or the like.

It is modular and insulated in feature to easily connect two or more wires together which is mostly arranged in a long strip easily connecting electrical outlets to the mains.

These terminal strips consist of a clamping component and a conducting strip which is flexible to the needs and variation of wires used.

Other than its flexibility they are also designed with bases that can be easily mounted or unmounted from a Printed Circuit Board (PCB) or a mounting rail, which are all readily available in various Terminal Blocks Manufacturers.

Since most of it is in strips in appearance, it is easier to increase its numbers according to your needs and keeps connection secure, safer and organized.

Types of Terminal Strips

Since terminal strips are convenient devices for connecting wires of various devices, they are categorized according to their structure and device types, may it be for appliances, automotive, and/ or industrial and commercial use.

If your equipment set up do not require a high voltage protection, then a screw-in connection is what you need. It is easy and doesn’t require much time to install because you just need to place the wires and screw it into the terminal block.

If you are going to use a plug-in connection, you connect the male terminal into the female port on the terminal strip or block.

• Get the right terminal block.

Once you have chosen the type of connection you would set up, the next step is to look for the terminal block that is appropriate and matching to your equipment’s requirements.

Choose the right size and shape for the number of wires you’re going to connect and pick the one with the highest current level for proper functioning.

• Secure the connection.

Whether you’re setting up the Screw-In or Plug-in make sure that you fasten and lock the connection.

Check for loose wires and tighten the screw in place to avoid dangers like fire or melt the insulation for your screw-in connection.

For the plug-in, run the electrical wires correctly and securely in the terminal block.

• Test and Correct.

After the installation of the terminal strip/block, check if the equipment will work. If it doesn’t work, you have to correct and check the wires and ports or use another terminal strip just to rule out if it is a broken one.
