Definitions

  • the present invention relates to an insert for terminal blocks,for quickly coupling four variable cross-section branching electrical cables.
  • terminal blocks or boards usually comprise a plurality of connecting clamps which are embedded in an electrically insulating supporting member made of rubber or plastics material.
  • Quick-coupling clamps are moreover presently known which are able of automatically restrain the end portions of conductor wires or cables by force fitting said end portions into corresponding seats formed in the clamp body.
  • the task of the present invention is to overcome the above mentioned drawbacks by providing an insert for terminal blocks or boards which affords the possibility of locking the branching electrical cables without the use of specifically designed tools.
  • a main object of the present invention is to provide an insert for terminal blocks or boards which also affords the possibility of easily and quickly removing therefrom said electrical cables if desired.
  • Another object of the present invention is to provide such a terminal block insert which is very simple construction-wise as well as very reliable in operation.
  • Another object of the present invention is to provide such an insert or clamp which,in its assembled condition,is constructed as a not disassemblable unit,­even if it is removed from its insulating material en­velope.
  • a quick-coupling insert or clamp for terminal blocks substantially consists of a metal tubular body,of rectangular cross-section and given size,at the ends of which there are respectively provided removable locking members for removably locking at least a live electrical cable and quick-coupling plug in members for removably quick-coupling one or more branching electrical cables,said removably quick-­coupling plug in members consisting of leaf spring pairs suitably restrained to said tubular body.
  • the insert or clamp for terminal blocks or boards according to the present invention which is indicated overally at the reference number 1,comprises a tubular body which is made by suitably bending an electrically conductive metal sheet or leaf 2.
  • This tubular body is provided,at one end thereof,with a cross bridge element 3 which is affixed to the side walls of said body and bears,at a middle portion, a rivetable lug 4.
  • a threaded throughgoing hole 7 adapted to receive a screw(not specifically shown) adapted to lock the live electrical cable against the bottom wall 8 of said tubular body.
  • This bottom wall is moreover advantageously provided with two inner parallel ridges 9 adapted to define a small central longitudinal hollow 10 for restraining one end of the mentioned live electrical cable.
  • tubular body can also be provided with pairs of flexible or resilient leafs 5 and 5′ at the two ends thereof.
  • tubular body 2 will be formed with further pairs of slots 6 and 6′ adapted to provide access from outside to the end portions of said resilient leafs.
