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.
