Terminal blocks, headers, plugs, and sockets are all essential electronic components that are widely used across various industries. This article will discuss the application field and working principle of 1971020000 terminal blocks. It will also focus on the different types of terminal blocks available and their purpose.

Terminal blocks, also known as "terminal boards" or "terminal strips," are rigid or flexible printed circuit boards used to connect wires, cables, or other components together. They are often designed to have multiple layers to accommodate different types of connections. Terminal blocks come in a variety of shapes and sizes, so it is important to select the type that is best suited to meet the requirements of the application.

Terminal blocks are typically used for cable connection in permanent wiring applications. They offer a secure and reliable connection point for both external and internal wiring. The most common type of terminal block is a single-ended terminal block, which has a single conductor recognized as the common “terminal”. This terminal is used to link all of the other terminals together.

The 1971020000 terminal blocks also provide a provision for three-terminal header plugs and receptacles, also known as a "test probe." These can be used for test applications to detect electrical signals or voltages. The terminal blocks are also designed to provide power transfer for low voltage-sensitive applications due to their low current capacity.

The working principle of a terminal block is fairly simple. It consists of a flat base, a top surface, and a series of connectors mounted on the top surface. The base of the terminal block is usually divided into sections and each section is labeled with a number indicating its specific purpose. Inside each of these sections are contacts that are connected to the external connector. The contacts come in two forms; a ‘top contact’, which is the uppermost layer of the terminal block, and a ‘bottom contact’, which is the lowermost layer. The contacts are brought together via a tightly wrapping coil.

When a connection is made, the top contact is connected to the bottom contact via a metal ‘spring’. This spring is designed to compress and expand. As it does this, it causes the contacts to move closer or further apart. This action places the connectors in alignment for the circuit to be connected. This process is referred to as a ‘make & break’ operation as the electrical current can be either connected or disconnected depending on the position of the spring.

Overall, 1971020000 terminal blocks are highly versatile electrical components that can be used in a variety of applications. They are robust, easy to use, and provide reliable connections in a wide range of environments. Furthermore, the mere fact that they offer a secure way to connect electrical wires and devices make them invaluable in any electronic system.
