What are the types of terminal blocks? Do you know what types of terminal blocks can be divided into?
Generally speaking, the types of analysis terminal blocks can be divided into four types: screw terminal block, barrier terminal block, push-in terminal block, and pluggable terminal block. The specific information is as follows:
1. Screw terminal block
Screw Terminal Blocks Terminal blocks that use screws as a method for holding cables or wires. Common screws have flat head fittings, and these types of terminals are often found where voltage and current requirements are moderate. Although the solder used to bind the wire to the terminal block has no insulating bond, if used properly, it can be very functional and can be used in permanent applications. It is important to be careful when tightening the terminal block, as over-tightening can damage the inserted cable, resulting in an unreliable and potentially dangerous connection.
2. Barrier terminal block
The barrier terminal is similar to the screw terminal, and both use screws as the structure to fix the cable. Barrier terminals typically have multiple termination points for the cables, so the barriers between the individual terminals are small. Barrier terminations can also have small covers and enclosures to further protect cables and are commonly found in household wiring and other high voltage scenarios where protection from arcing or potential short circuits is required.
3. Push-in terminal block
Push-in terminals use small spring-loaded rods that allow the cable to enter the terminal box in one direction, but the connection should be strong enough to effectively hold the wire in place, also known as a "push fit". This type of product, in contrast to screw terminals, relies on a spring with sufficient force to keep the wire in contact with the conductor. Another problem with it is that some are not reusable and there is no disassembly rod, which makes repair work difficult as the entire terminal may need to be replaced.
4. Pluggable terminal block
Pluggable terminals are those that have a cable entry to allow a wire or cable to be connected but a plug output to allow easy connection to an outlet. These types of terminals can be important when hot swapping, but can be removed when connection is expected, useful in the case of repairs or inspections. Threaded contacts are the most common connection method for plugging in cables, but screws usually have a small metal plate attached to the end that can clamp both small and large cables.
After reading the above content, you should have a basic understanding of "types of terminal blocks".
