Terminal Blocks - Barrier Blocks

Barrier blocks are a type of terminal block in a circuit that is designed to prevent the flow of electricity from one section to another. They are used in various applications, such as automotive, industrial, and medical, which require the electrical connection between components with limited risk of shock or burnout. A barrier block is typically composed of a pair of insulated metal plates that are attached to a metal bar. When an electric current is applied to the terminals, the metal plates act as a barrier preventing the current from transferring between the two sections. Barrier blocks are often found in automotive and industrial circuits, as well as in medical applications due to their high current-carrying capacity.

Application field

Barrier blocks are used in a wide range of applications, including in automotive, industrial and medical fields. In the automotive field, they are used to isolate electrical components such as sensors and switches from the main circuit. In the industrial field, they are used to protect wiring connections from overload, shock and vibration. In the medical field, barrier blocks are commonly used to protect sensitive electronic equipment from voltage, current and temperature variations.

Working Principle

The working principle of a typical barrier block is based on the insulation and capacitance of the two insulated metal plates. When an electric current is applied to the terminals, the capacitance between the two plates is increased, creating a barrier that prevents the current from transferring between the two sections. This type of barrier block has a relatively high current-carrying capacity and its design also prevents short circuits from occurring. In addition, the use of a special insulating material ensures that the current remains within the desired range, thus providing additional protection.

Barrier blocks are a versatile and essential component in various electrical circuits. Through these insulation and capacitance features, they enable safer connections between components in the automotive, industrial and medical fields. By preventing the transmission of electricity from one section to another, they also help to ensure a more reliable and stable operation of the circuit.
