Definitions

  • the present invention relates to an improved terminal block for the electrical connection of rigid or flexible electrical wires or cables.
  • terminal blocks are constituted by a plurality of adjacent and mutually connected terminals provided with pairs of holes, interconnected by conductive bodies into which a conductor can be introduced and clamped with a screw.
  • These conventional terminal blocks require a tool to be used for tightening and removal of the screws, and this of course takes up a not inconsiderable operating time for correct manipulation of the screws themselves.
  • branching connections in a simple manner, particularly after the main connection has been made.
  • the object of the present invention is that of providing a terminal block for the connection of electrical conductor wires or cables, which will be of a structure such as to facilitate the electrical and mechanical fixing of the wires or cables to the terminal body in a manner which avoids the above-indicated disadvantages.
  • a terminal block for the electrical connection of conductor wires or cables characterised by the fact that it essentially comprises a generally rectangular box-like body having at least one aperture in each opposite end wall thereof and housing within it a generally trapezoidal three dimensional structure made of electrically conductive elastic material, the shorter parallel side of the trapezoidal structure being defined by a reaction plate which projects beyond the two inclined sides of the trapezoidal structure, which latter sides are formed as elastic tongues integral with a plate constituting the longer parallel side of the trapezoidal structure with the free ends of the tongues closely adjacent the face of the reaction plate such that the free end of a conductor wire or cable inserted through the corresponding aperture in the adjacent end wall of the box-like body can be introduced between the reaction plate and the free end of the adjacent inclined tongue and retained thereby.
  • One advantage of the present invention is that it provides an improved terminal block which allows the interconnection of both rigid and flexible electrical conductor wires or cables.
  • Another advantage of the present invention is that it provides an improved terminal block having smaller dimensions than conventional terminal blocks but which is readily interchangeable with conventional screw-type terminal blocks.
  • a three dimensional structure shaped in the form of a trapezoid made of an elastic electrically conductive material, the shorter parallel side of which is defined by a plate which also projects beyond the two inclined sides of the trapezoidal form itself, and the dimensions of which, in plan, match those of the major base.
  • apertures On opposite ends of the box-like body there are formed apertures to receive the ends of conductive wires, and in the upper face of the box-like body and in the said plate defining the shorter side of the trapezoid there are formed openings in corresponding positions to receive a tool or other means for facilitation of an electrical connection as will be described in more detail below.
  • the improved terminal block of the invention is constituted by a plurality of generally rectangular box-like bodies 1, laterally interconnected together, and each closed by an upper cover 2.
  • these rectangular box-like bodies there are two openings 3 having respective frusto-conical longitudinal entrance sections.to facilitate the introduction of the ends 4 of conductor wire 5 to be connected.
  • a three dimensional conductor structure 6 having a substantially trapezoidal form, preferably made of stainless steel or, in any event,of a material which is conveniently elastic and a good conductor of electricity.
  • This conductor structure is constituted by a base plate 7 folded upwardly at each end to form two inclined tongues 8 converging towards their free ends, and at one side to form a side wall 9 laterally from which projects an upper portion 10 which overlies the inclined side tongues and projecting over these to form a reaction plate the function of which will be explained hereinbelow.
  • the said reaction plate has an intermediate slot 11 extending transversely of the length of the block with two longitudinally extending slots 12 one on each side of it.
  • the inclined tongues 8 are divided longitudinally into two portions by means of a corresponding slit 13.
  • the cover 2 for closure of the box-like body 1 has apertures 14 in positions corresponding to- those of the slots 12 in the reaction plate 10 to permit the passage of the tip of a screwdriver 15 or like tool for the purpose of causing flexure of one or the other of the tongues 8 as illustrated in Figure 5.
  • the insertion of the end of a flexible wire between a tongue 8 and the reaction plate 10 of the structure 6 is, as is illustrated in Figure 5, considerably facilitated; when the tool is removed the tongue 8 springs back pressing the wire into contact with the reaction plate 10 making a mechanical and an electrical connection simultaneously.
  • a cover with levers 16 incorporated directly by moulding in the cover itself can advantageously be provided.
  • Such levers may advantageously have different colours for a more rapid identification of the poles; each lever is provided with an underlying plastic tooth 17 capable of acting, as shown in Figure 7, on the tongues 8 of the structure 6.
