Terminal Blocks - Barrier BlocksA20210204OJ2 application field and working principleTerminal blocks, also known as barrier blocks, are electrical connecting components used to connect two or more electricalconductors together. These blocks provide a secure connection between multiple wires in an electrical system. Terminal blocks are designed to provide reliable connections for power distribution, ground wires, control wiring, and data cable. Barrier blocks are used in both industrial and residential applications, and are especially common in industrial use.Terminal blocks are typically made ofhigh-temperature resistant material such as aluminum, brass, or plastic. The insulated frame of the terminal block provides protection from electric shock and prevents wires from shorting. They come in many shapes and sizes and can either be mounted to a surface or suspended in the air.When looking to install terminal blocks, it is important to read the instructions carefully and follow them to the letter. Proper installation is key to maintaining a safe and dependable connection. Improperly installed terminal blocks can cause unwanted electrical shorts or open circuits, leading to system failure.Terminal blocks are available in two basic configurations: unshielded and shielded. Unshielded terminal blocks are made out of copper or aluminum and are typically used in industrial electrical systems. Shielded terminal blocks are made out of plastic and offer better protection from electric shock compared to unshielded. Shielded terminal blocks also provide more reliable ground connections.When installing terminal blocks, it is important to make sure that the conductor wires are securely connected to the terminal block. To make this connection, the terminal block should be inserted as far as it can go into the wire insulation and secured using a screw or set screw.Once the wire is secured to the terminal block, the block should be properly secured to the panel, wall, or surface. This can be done using bolts, rivets, or clips. A terminal block must also be securely wired in order to maintain an effective connection. This requires connecting the wires from the device to the proper terminals using the screws provided.The A20210204OJ2 terminal block is a type of barrier block. It is designed for USB 2.0 Type A and Type B connectors and is compatible with many electronic devices. The terminal block has three contact points and two screw connections. The block is designed so that the contact points are easily accessible and the connecting screws are securely fastened. The A20210204OJ2 terminal block provides reliable connections for USB devices.In summary, terminal blocks, or barrier blocks, are used to connect two or more electrical conductors together. They come in many shapes and sizes and either be mounted to a surface or suspended in the air. A20210204OJ2 is a type of barrier block designed for USB Type A and Type B connectors and is used to provide a reliable connection for electronic devices. Properly installing terminal blocks is key to a safe and reliable connection.
