Terminal blocks ensure safe currents as well as safe wiring of installations

2020-12-09

From control panels for industrial productions to fuse boxes in private homes: Terminal blocks ensure safe currents as well as safe wiring of installations. Plastics used to manufacture terminal blocks have to meet high requirements for fire protection and mechanical and thermal properties.

In electrical engineering, terminals are used to connect wires and cables. Continuous safe contact has to be ensured for the connection mechanical fixing ensures this. Terminal blocks can be arranged in any order on a mounting rail and installed with a simple snap.

This defines the mechanical properties required for this material: plastics used in this application must exhibit high elasticity and good toughness or run the risk of breakage when snapping. Connections require sufficient stiffness and strength.

When handling electrical power, sparking and fires may occur. Other requirements include high temperature resistance and heat aging resistance

Plastics have electrical insulating properties, which generally recommends them for electronic applications.

Terminals are produced in extremely large quantities by injection molding. Economic production requires short cycle times and low maintenance cost for injection molding tools and machinery. It is also necessary to be able to produce very low (0.4 mm) wall thicknesses with the plastic.

In addition, good colorability of the material plays an important role: Different colors of the terminal blocks serve to differentiate between different functions (e.g. neutral conductor, protective conductor, etc.) and ensure safe installation.

Due to the high requirements , PA66/6 copolyamid are especially suitable for the application in terminal blocks..The Terminal Block made from NYLON with V0 Flame retardant and the conductor is Copper with good conductive, stainless steel spring make the wire not easy fall down from the terminals.
