What are the advantages and disadvantages of terminal blocks?

When assembling a circuit, it is not only the assembly process of wires and soldering that should be paid attention to, but the terminal block is also a crucial component. So what is the main function of the terminal block? What do you need to know about it? What are the advantages and disadvantages?

Terminal blocks, also aptly called "screw terminals", are essentially a form of electrical interchange that distributes power to your equipment. Terminal blocks are often used in the automotive electrical field and are a routing tool that connects different circuits within and to each other.

The general terminal is made by stripping the wire insulation, wrapping it around the screw, and then fixing the screw in the terminal to achieve the connection, also called screw connection. The second method is to solder the connector to the wire and connect it to the terminal and the wire to the terminal block. Usually in automotive electric you will see more connections using the second method, but there may still be screw connections in some devices. Terminal blocks are designed for quick and easy connections that can be made quickly and fastened quickly.

Typically, terminal blocks serve two purposes, namely to connect different circuits together and to provide electrical grounding for the circuits. Of course, grounding provides a safe route for circuit termination, reducing the risk of short circuits inside the system and serious injury to team members. Connecting different circuits can be a time-consuming task, making terminal blocks easier to connect, but for circuits that require more intense interaction, a different technique may be required.

Main advantages of terminal blocks: The main advantage of terminal blocks is cost, terminal blocks are relatively inexpensive compared to other types of connectors. To a certain extent, it also saves time relatively, because connecting wires is not a complicated process, which can be easily done by any skilled terminal wire manufacturer.

Main disadvantages of terminal blocks: The main main disadvantage of terminal blocks is that in the presence of vibration or shock, the wires may come loose from the terminal block, even if the connection is firm. Therefore, the device should be tested as firmly as possible before use to ensure that it can withstand the rigours it is exposed to. Another potential downside is space, because of their construction, terminal blocks can only be so small.

When selecting terminal blocks, identify needs and understand potential concerns. Most terminal blocks are purpose-built and they are best used in the electrical field. Terminal blocks are convenient and provide fast and efficient connection and circuit distribution to equipment.
