5.00mm side entry screw terminal block connectors, 2 ~ 24 poles
Description:
A terminal block exists in order to offer you the space to connect
more than one cable to the same connection or point. It is a
convenient way of connecting cables and making them electrically
common (receiving the same charge) without taking more space.
The other reason is versatility, in a circuit where connections or
cables need to be exchanged or modified often, terminal blocks give
you an easy and still sturdy way of doing that.
Terminal bodies typically consist of a copper alloy with the same
expansion coefficient as the wire intended for use. This not only
prevents loosening because of differing expansion rates but also
reduces corrosion caused by electrolytic action between two
different metals.
Applications:
It is widely used in almost all electronic equipment, such as small
eletronic watches, calculators, general computer, communication
electronics equipment, military weapon systems, etc.

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:
• 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.
