Terminal Blocks – Headers, Plugs and Sockets comprise of insulation displacement connectors which are mostly used for providing union points in all the electrical applications. Connecting wires in either ribbon form or as an individual entity is the purpose of these items. It can provide durable and efficient electrical joint and saves time when it comes to maintenance or repairs. Due to this advantage, it is one of the widely used electrical together with other RJ45, D sub connectors etc. One can find numerous styles of terminal blocks in the market as it is manufactured in various model and sizes to meet different requirements. Its application field and working principle will be discussed in detail in this article.

Terminal Block - Application Field:

Terminal blocks are often used as a connector and a union point in a cable connector such as providing electrical connection between different cables, optical fiber cables, and telephone cables. It can also be utilized as a point of transferring current between different levels of voltage. In addition, application in signal transmission and electrical networking communication can also be found. This connector is commonly used in the electronic industry for SmartMeter, Electronics Control, Automation Instruments and Business Instrument. It can also be utilized in the electrical industry for Lighting System, Signal Transfer and Power Distribution.

Terminal Block – Working Principle:

The working principle of Terminal Blocks relies on the principle of insulation displacement. When the wire is inserted into the terminal block, the insulation and the wire conductor is being connected due to the piercing head that is internally located in the terminal block. This piercing head is also known as a sharp metal blade that is inserted into the lower layer of the insulation of the wire. The sharp blade helps to penetrate the insulation of the wire and contacts with the wire conductor which forms a connection. Once the connection is made, the current can flow from one wire to another.

In addition, there is also an increasing demand for terminals with safety feature. This kind of terminals can be found in form of screw terminal, spring terminal, and pluggable models etc. They are designed to provide safe connection between wires. For example, screw type terminals requires the user to screwcap in order to ensure tight electrical connection which reduces the possibility of loose connection due to vibration. This safety feature makes this product more suitable for more hazardous working environment.

Conclusion:

Terminal blocks are essential component in the electrical industry as it serves as a connector and union point. Its application involves various electronic and electrical industry and its principle is based on the concept of insulation displacement. Not only that, there are also certain type of terminal blocks that provide safety features in order to ensure the quality and robustness of the connection. Due to its advantages, Terminal Blocks – Headers, Plugs and Sockets is a common component found in the electrical industry.
