Feed Through Terminal Blocks - Screw Connection with spring support
Vibrations adversely affect terminal connection, causing loosening of conductors and consequent overheating of terminal blocks. elmex Terminal Blocks are therefore designed to be inherently resistant to vibrations in normal applications. However, high vibrations can arise due to vibration-affected installation sites, such as installations in and around mines, proximity to a heavy machine shop, forging/ die casting shops, cement/steel plant machinery, textile machines, and so on. Special designs for high-vibration applications are also preferred in some Power Projects, Power Distribution Centers, Motor Control Centers, and Relay Control Panels. depending on the proximity of vibration-generating equipment. elmex Standard Screw Clamp design, with compression springs, provided under the clamp offers a reliable solution for high-vibration applications of Terminal Blocks. These are called "SPRING LOADED" terminal blocks. For inserting the conductor, clamping screws should be unscrewed and pressed, which results in pushing down the contact clamp against spring action and creates space for conductor insertion below the current bar. When the screw is tightened with specified tightening torque, the clamping part moves to cause gripping of the conductor with the current bar, as with the normal clamping process, but in the case of spring-loaded design, the conductor is gripped with additional clamping force exerted by the compression spring from below the clamping part.
