What’s there to know about terminal blocks ?

Types of terminal blocks
There are a large variety of terminal blocks for varying needs. General-purpose types are broadly usable in many applications as simple termination points to make electrical connections. Other examples include terminal blocks for I/O, for power distribution, as well as for motor connections, both single-phase and three-phase motors for various industrial uses. Other common types include ground blocks designed specifically for making a connection to ground and fuse blocks where two wires make a connection to a fuse, providing circuit protection.
Wires are inserted on the side and make contact with a conducting bar and are secured in place with a screw tightened from the top.

Another common way to classify terminal blocks is by the method of terminating the wire or making the connection. Terminal blocks are available with a number of different connection methods. The most common are screw-in types where the wire is pressed against a metallic conducting plate or bar and tightened down with a screw to secure it physically and make an electrical connection. 

Spring-loaded terminals use the force of a spring to maintain the connection of the wire to a conducting plate. There are also push-in terminal blocks where a wire attached to a ferrule is inserted into a hole in the block. Other types include insulation-displacement connectors (IDC) that don’t require the wire to be stripped prior to insertion into the Terminal Block.

Our Push In Terminal Block is more convenient than other Universal Terminal Block .You can install the wire directly with any tools, we can compare with the screw type terminals block. As you it is very convenient and fast , saving at least 50% insert force and installation time.

The most basic definition is that it provides an electrical connection point for two or more wires. Terminal blocks were originally referred to as screw terminals because a screw was used to secure wires to a conducting plate, making an electrical connection. In control systems, terminal blocks are used to connect panel-mounted equipment to power and field wiring.
