Terminal blocks, also known as terminal boards or strips, provide a convenient means of connecting individual electrical wires. They enable quick and easy connections and disconnections to be made between different circuits, and provide an easy way of interconnecting components such as switches, meters, and other electrical systems. The type of terminal blocks most commonly used are called header, plug, and socket. The 691373500021B series is one of the most popular terminal blocks on the market and is widely used in various industries.

691373500021B header terminal blocks are insulated blocks that have male or female pins arranged in a straight line. These terminal blocks come with screw, spring, or other clamping mechanisms which allow wires to be connected directly to the block pins without the need for soldering. They are designed for easy installation and can be mounted on the back of a circuit board, panel, or other mounting surface. These terminal blocks are typically available in multiple sizes and configurations, with 4-20 pins per block. Connecting wires to these header blocks is done by inserting the end of the wire into the space between the pins and then tightening the screws on the other side of the block to secure the connection.

691373500021B plug terminal blocks are insulated blocks that have male or female pins arranged in a straight line. These terminal blocks come with contacts that are placed in the block and are designed to mate with other similar contacts at the other end of the connector. This makes them suitable for consumer electronics as they offer quick and easy connection and disconnection of devices. The plug blocks are usually available in multiple sizes, with 4-20 pins per block. Connection of individual wires is done by inserting the end of the wire into the block contact and then plugging the block into the appropriate mating piece.

691373500021B socket terminal blocks are insulated blocks that have male or female pins arranged in a straight line. These terminal blocks feature a connector on one side that allows for connection of a wire to the block pins. The other side has sockets which enable connection of a mating component to the block. Socket blocks are usually available in multiple sizes, with 4-20 pins per block. Insertion of wires into these blocks is done by inserting the end of the wire into the space between the pins and then tightening the screws on the other side of the block to secure the connection.

All of the 691373500021B series terminal blocks are designed with a common working principle. They allow for quick connection and disconnection of various electrical components and circuits. They enable easy installation and come in a variety of sizes and configurations. These terminal blocks are suitable for consumer electronics and industrial applications, and are widely used in various industries. Additionally, these blocks feature insulation between the pins to ensure safe operation.

In summary, the 691373500021B series terminal blocks provide a convenient way of connecting individual electrical wires. This series is available in three different types, namely header, plug, and socket, which all feature the same basic working principle. These blocks are suitable for both consumer electronics and industrial applications, and are widely used in various industries due to their easy installation and insulation capabilities.
