Terminal Blocks - Accessories

Terminal blocks, sometimes referred to as terminal strips or terminal stations, are one of the essential components of electrical and electronic equipment. In this article we will discuss the 1186720000 application field and its working principle.A terminal block is an electrical component that provides a convenient connection point between different electrical components. It is typically composed of a set of insulated terminals, which are attached to either brass contacts or screw terminals. The terminals are designed to accommodate stranded wire of various gauges and types. The terminals can also be used to connect multiple wires together, allowing for the creation of various patterns or configurations. Additionally, some terminal blocks come equipped with jumpers, which are used to provide a secure and reliable connection between two separate terminals.Terminal blocks are typically rated for specific voltage and current loads to ensure the safety of the wires and components connected to it. Common ratings range from 30V to 250V with a maximum of 15A. This type of rating is also important in determining the type of connectors and wires that can be used with the terminal block. For example, a terminal block with a rating of 30V and 15A is not suitable for use with heavy-duty wires, such as those used for lighting and other high-voltage applications.Terminal blocks are used in a variety of applications, ranging from industrial, consumer, and commercial to military and aerospace. They are commonly found in electrical systems used for machine control, instrumentation, and process control. Industrial automation systems rely heavily on terminal blocks for power and signal distribution. Consumer and commercial applications for terminal blocks include residential homes and automobile wiring.The working principle of a terminal block is fairly simple. Electric current flows through the terminals, creating an electric field. This field then causes electrons from the metal contact to move towards the terminal or vice versa. This movement of electrons creates a contact resistance, which is equal to the total resistance of the circuit. This resistance allows the electrical current to continue flowing through the circuit without experiencing any resistance. This is why it is important for the terminals of a terminal block to be closely spaced, as this will ensure that the contact resistance is kept to a minimum.In order to avoid corrosion and other damage to the terminals, it is important to regularly clean the terminals and establish an anti-corrosion layer. This is typically done by using a terminal block cleaning brush or a corrosion inhibiting compound. The terminal block should also be inspected regularly for signs of damage, such as chafing or deformation, and be replaced as soon as possible if necessary.Terminal blocks can be made from different materials, including insulating plastics and metals such as tinned copper, zinc-plated steel, brass, nickel-plated steel, and even aluminum. Each material has its own advantages and disadvantages. Aluminum blocks are more lightweight than steel blocks and are often used in applications where corrosion-resistance is required, such as on boats and in outdoor applications. Steel blocks are more durable and are typically used in industrial applications.In conclusion, terminal blocks are essential components of electrical and electronic equipment. They are used to provide a convenient connection point between different electrical components and can come in a variety of sizes, ratings, and materials. It is important for the terminal blocks to be cleaned regularly and inspected for damage in order to maximize their effectiveness.
