  • This invention relates to the technical field of electrical devices or apparatuses and, more particularly, relates to a terminal for electrical spring connection for an electrical device or apparatus.
  • electrical devices or apparatuses of the above type include, for example, electrical sockets and plugs, electrical control switches installable on a wall, electrical control switches installable in industrial or domestic electrical panels, and so on.
  • a terminal for electrical spring connection belonging to the prior art typically comprises a metal frame, adapted to function as an electricity busbar, which is housed in a main body made of electrically insulating material of an electrical device or apparatus.

  • This leaf spring normally comprises one or more arms to hold against the metal frame the one or more electrical conductors to be connected.
  • the aforesaid terminal for electrical spring connection described with reference to the known technique is not free from defects.
  • such terminal for electrical spring connection does not always allow obtaining a high hold of the electrical conductor and thus an acceptable electrical conduction between the electrical conductor and metal frame, for example due to the fact that these latter are in contract with each other for only a portion, often small, of the electrical conductor.
  • the assembly of such a terminal for electrical spring connection can be more complex and, therefore, not as fast, because of the need to insert and attach the leaf spring into the respective mounting opening with which the metal frame is provided.

  • the wiring of the electrical device 100 by the installer is finished.
  • the purpose of the invention is fully achieved since, as mentioned earlier, the terminal for electrical spring connection according to this invention, the light of the conformation of the conductive element (conductive frame or terminal block), allows a greater ease of assembly and wiring of the terminal, requires a more rapid stripping of the electrical conductors (minimum length stripping reduced) and ensures a high hold of the electrical conductor or cable inserted in the terminal, consequently allowing the use of lever mechanisms that are softer to operate.
