Know A Few Facts about Terminal Blocks

In most electrical systems including aircraft, terminal blocks are one of the essential parts that are commonly used.Terminal blocks comprise insulated connections with an insulating framing and a certain clamping system that connect and support two or more cables or wires. Instead of using any twist-cap connector, you can also connect 2 wires with a certain terminal block.

Let us know a few facts about one of the important aircraft electrical parts in this article. You can easily buy these connectors from Parts Cage Inc.

  1. No crimping required

It will not be necessary to crimp your wires or cables ifyou are going to use any terminal block. However, there can also be certain exceptions in a few cases, but most terminal blocks will not require crimping.

If you want to use them, then you need to just insert the cables or wires into the available open ports available on the sides. Thereafter, you can clamp the entire exposed ends of your cables or wires by tightening the necessary screws over them.

  1. Barrier terminal blocks are available

While you go shopping for any terminal blocks, then you may also find barrier terminal blocks. Still, such barrier terminals blocks can be used for connecting multiple cables or wires just like all other terminal blocks.

The only difference will be that a barrier terminal block will feature a ring terminal for further protecting the cables or wires from loosening.

  1. Easy to install

Generally, terminal blocks can be easily installed. As we mentioned before, they need not be crimped. Therefore, you will not need any crimping tool for installing terminal blocks.

All you need is a screwdriver and also a wire stripper/utility knife. Using a screwdriver you can clamp the cables or wires in your terminal block, whereas any wire stripper/utility knife will enable you to easily cut away the cable or wire’s protective outer layer available on the ends.

  1. Offers organization

Mostelectricians will prefer terminal blocks instead of traditional connectors as they may offer the organization. A terminal block will just not connect cables or wires but also organize them.

When you connect with terminal blocks, the cables and wires will be neatly organized so that you can easily manage and identify them in the future. Few electricians may also color-code the terminal block top to label all the connected cables or wires.

  1. Push-fit terminal blocks are also available

Besidesbarriers, the terminal block may have another alternative which is push-fit, which is also called a push-in terminal block, and they justify their name as they need nothing but only “push” to use.

Such a push-fit kind of terminal block has to just push the cables and wires or you can cable into it. When you push anycable or wire into any push-fit terminal block, then it is going to clamp down.


Wire and cable terminal blocks can be a practical way to connect wires and cables. A screw must be tightened over each cable or wire in typical terminal blocks. Wires or screws can be inserted straight into the terminal block with push-fit terminal blocks, and they will clamp in place.

Minimal blocks will be insulated connections with a certain insulating frame with a clamping system that connects two or also more wires.
