Low voltage 3.81mm pitch pluggable connector , male type 2 ~ 24 poles
Description:
How do we connect two wires ? By stripping the insulation at the ends and twisting them together? Yes, it works. But, is it safe? We can apply insulation tape over the joint or use a wire connector. But what if there are a number wires that need to be joint/connected near each other? Or, what if multiple outgoing wires are to be connected to a single incoming wire? Then this method will neither be safe nor be convenient anymore. Here we use terminal blocks.
Terminal blocks, for wire to board connection. Terminal block in two parts that can be separated, one part for cable connection, and one part for PCB mounting.This solution enables to easily connect and disconnect.
Compared to other types of connectors, terminal blocks are low in cost. And it can be re-used in the field, allowing for the replacement of wires or equipment, generally with standard hand tools. It usually avoid the requirement for a specialized mating connector to be applied to the ends of wires.
Applications:
The terminal blocks are used in almost all electric appliances that need 240-volt power supply.

Terminal blocks selection guide:
The difference between blocks can lead to problems if an incorrect
type is used or if it is not connected properly. Follow the
advice below to choose the right one:
• Look at the electrical equipment you are working on to see what
type of connection it requires; normally you will have either a
screw-in or plug-in connection. Screw-in wires are placed inside
the terminal block and screwed into position, and they are most
common for equipment that does not require high voltage protection.
A variation on the screw-in connection is one held in place by a
spring mechanism. This connector can reduce the time spent on the
job because you simply clip it into place instead of removing and
replacing the screw.
A plug-in connection has a male terminal at the end of the wire.
This terminal is connected to the female port on the terminal block
and forms a secure connection. Plug-in blocks are commonly used in
the fuse boxes of automobiles.
• Once you know the type of connection that is required, you need to
find a terminal block that fits the rest of your requirements.
Consider what space you have for the connection and how many wires
need to be connected. Terminal blocks are supplied in a variety of
shapes and sizes, so you should be able to find one that suits your
needs.
• Choose the correct rating. 3A, 5A, 15A, or 30A terminal blocks are widely available, and you'll want to buy the one that meets the highest current level that it will conduct in order to allow the most powerful piece of equipment to function.
