Definitions

  • the present invention relates to an integrated terminal block construction fixedly associated with an electric plug.
  • the aim of the present invention is to solve the above mentioned problem by providing an integrated terminal block construction, fixedly connected to an electric plug, which can be directly coupled to the housing of the electric apparatus, while providing an easy access to the electric contacts for the connection of the inner electric elements of the apparatus, and being simultaneously already coupled to the plug for coupling the apparatus to the mains.
  • a main object of the present invention is to provide such a terminal block construction which allows to make very simple connection operations and which, moreover, provides very accurate low contact resistance electrical connections.
  • Another object of the present invention is to provide such an integrated terminal block construction, which is very safe and reliable in operation.
  • Yet another object of the present invention is to provide such a terminal block construction which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • this prior terminal block arrangement comprises a terminal block body coupled to an electric cable associated with an electric plug, said terminal block further comprising, on a surface thereof, electric contacts which are coupled with the wires of said electric cable, said terminal block body also including means for coupling said body to a supporting sheet metal plate with which the ground contact of said terminal block arrangement can be associated.
  • EP-A-0 368 074 discloses a plug assembly which can be coupled to a supporting wall by resilient latching means cooperating with an edge portion of a window formed in said supporting wall.
  • the integrated terminal block construction fixedly coupled to an electric plug, generally indictaed at the reference number 1, is provided with a terminal block body 2, made of a plastic material which, advantageously, is connected to an electric cable 3 which in turn can be fixedly coupled to an electric plug for connection with the electric mains.
  • the terminal block body 2 is provided with lug elements 4 (Fig. 7) for locking the cable, provided for preventing said cable from accidentally disengaging from the terminal block body 2.
  • the terminal block body 2 is provided with a plurality of electric contacts, generally of the so-called “Faston®” type, which can be separated, for each pole, by separating elements 15 made of an electrically insulating plastic material, or they can also receive a coupling movable portion either of a single or multiple type.
  • separating elements 15 made of an electrically insulating plastic material, or they can also receive a coupling movable portion either of a single or multiple type.
  • each contact 10 has a U-shape configuration with two arms 11 of Faston® shape, said arms 11 being connected at the central portion thereof by a bridging element 12 (Fig. 7) in which, by a cutting operation, is separated an intermediate portion, indicated at 12a, which can be spread apart with respect to the remaining portions so as to provide a passage therein the conductors 3a of the cable can be engaged and locked in the engaged position by mechanically deforming the central portion 12a.
  • the terminal block body is moreover provided with coupling or latching means for connecting it to a shaped window arrangement 20, which is formed through the holding sheet metal material or housing of the apparatus to which the terminal block must be connected.
  • Said coupling or latching means are provided with a cut-out seat 25 (Fig. 3), formed in the bottom portion thereof, which will be practically arranged bridging an edge portion of the window arrangement, whereas, at the other side, there is provided a resilient lug 26 (Figgs. 6, 10) including a locking tooth element 27 and a projection 28 which outwardly projects and which allows a tool to be engaged therein in order to obtain, if required, the disengaging thereof.
  • said terminal block body is further provided with a laterally projecting plate 30 (Fig. 9), for providing a ground contact, which is directly performed by restraining it on the sheet metal 21 which, advantageously, can comprise a plurality of holes 31 for applying fixing screws or rivets.
  • the above disclosed terminal block can also be provided, on its portion opposite to the electric contact portion, with plug holder seats 40 for receiving the electric plug for connecting the apparatus to the mains, as the electric cable is disengaged fron the power supply mains, thereby preventing the cable from being held in a free condition.
  • the terminal block body there are provided two seats or recesses, corresponding to the plug elements of the electric plug, which will allow the electric plug to be properly removably restrained in its condition coupled to the electric cable.
  • the number of the contacts provided on the front face, as well as the mutual arrangement thereof, can be varied according to the requirements.
  • the wires of the electric cable are clampled to the central portion of the Faston-type contacts, which have a U-shape, by exploiting a cut-out of the central portion which, practically, defines a passage therein the conductor can be restrained.
