Definitions

  • the present invention refers to a terminal board for the electrical interconnection of electrical conductors in accordance with the preamble of claim 1.
  • terminal boards for example of the type known as mammoth, if it is necessary to electrically interconnect the ends of different electrical conductors.
  • multi-way terminal boards for example three-way or four-way, should it be necessary to independently and selectively electrically interconnect the top ends of a first plurality of electrical conductors with the top ends of a second corresponding plurality of electrical conductors, thus having two, three or multi-way terminal boards.
  • electrical connectors are equipped with clamping means, for example using a screw, suitable for engaging the top end of the electrical conductors inserted in the electrical connectors themselves, ensuring that they do not come off.
  • the aforementioned terminal boards are housed inside containing cases that are assigned the task of ensuring the necessary degree of protection and/or insulation.
  • Terminal boards up to three-way have a linear arrangement in which the electrical connectors of the terminal board are arranged alongside one another, whereas, in order to contain the bulk, in terminal boards with a greater number of ways the electrical connectors are arranged according to a modality that foresees dividing the electrical connectors into two overlapped groups of side-by-side electrical connectors. For example, in the case of a four-way terminal board, there are two overlapped pairs of electrical connectors side-by-side.
  • the requirement to be satisfied is therefore that of having a multi-way terminal board capable of simplifying the wiring operation between the top ends of the different electrical connectors also in conditions of restricted space where the use of tools such as a screwdriver is complicated.
  • the problem forming the basis of the present invention is to devise a terminal board for the electrical interconnection of electrical conductors that has structural and functional characteristics such as to satisfy the aforementioned requirement, at the same time avoiding the aforementioned drawbacks with reference to the prior art.
  • reference numeral 1 globally indicates a terminal board for the electrical interconnection of electrical conductors K.
  • the terminal board 1 comprises a body 2 of electrically insulating material, for example a plastic material, inside which a plurality of electrical connectors 3 of electrically conductive material, for example brass or copper, is housed.
  • the figures illustrate the case of a four-way terminal board, in other words a terminal board equipped with four electrical connectors capable of interconnecting four different pairs of electrical conductors.
  • the electrical connectors 3 are housed inside the body 2 in such a way as to be electrically insulated from one another.
  • Each electrical connector 3 is arranged to interface and make a firm and stable connection with the ends of the pair of electrical conductor to be connected. In accordance with the preferred embodiment illustrated in the figures, this is obtained thanks to the fact that each connector:
  • the latter is equipped with corresponding passages 5 suitable for placing each opening of the electrical connectors 3 in communication with the outside of the body 2.
  • clamping means 4 can be of various types, for example screw, clip or jointed.
  • the clamping means 4 are in the form of screw clamping means comprising, for each of the aforementioned openings, a respective screw of conductive material, for example brass, extending transversally to the tubular element defined by the electrical connector. More specifically, the tubular element has a through hole with mother screw thread with which the aforementioned screw is in threaded engagement to insert transversally inside the tubular element to clamp onto the portion of the electrical conductor inserted in the tubular element itself.
  • Figure 2 shows a piece K of electrical conductor projecting from a tubular element of a connector 3, whereas the screw of the fastening means 4 of such an electrical connector is engaged by the tip of a screwdriver S to be set in rotation.
  • the electrical connectors 3 are housed in the body 2 so as to all be parallel to one another with the opposite open top ends of the tubular elements facing towards a front side and a rear side of the terminal board 1. At the aforementioned front and rear sides the body 2 there are the aforementioned passages 5.
  • the insulating body 2 can consist of a casing in which to house the electrical connectors 3 or it can consist of a layer of insulating material moulded over the electrical connectors 3.
  • the insulating body 2 of the terminal board 1 is divided into at least two distinct portions that are connected together through hinged connection means 6 so as to be able to articulate one with respect to the other around a predetermined rotation axis X-X.
  • the body 2 is divided into two portions 9 and 10 that, thanks to the presence of the hinged connection means 6, allow one to be rotated with respect to the other around the rotation axis X-X, so that the body 2 is able to be closed in a book-like fashion to go from an extended configuration (cf. figures 2 and from 4 to 7) to an overlapped configuration (cf. figure 1 ) in which the aforementioned articulated portions 9 and 10 are substantially side-by-side extending on from one another and, respectively, they are brought together overlapped one another.
  • Figure 3 illustrates the body 2 in an intermediate step of the rotary book-like closing movement (indicated in the figures indicated by the arrows).
  • each of the two articulated portions 9 and 10 it is possible to identify an inner side, 9a and 10a respectively, and an opposite outer side, 9b and 10b respectively, being specified that the inner sides of the two articulated portions 9 and 10 face one another when such articulated portions 9 and 10 are brought together overlapped one another in the aforementioned overlapped configuration of the body 2 (cf. figure 1 ).
  • the electrical connectors 3 are present both in the articulated portion 9 and in the articulated portion 10.
  • the four-way terminal board 1 has two electrical connectors 3 housed in the articulated portion 9 and two further electrical connectors 10 housed in the articulated portion 10.
  • each articulated portion 9, 10 defines a container, in which to house the respective electrical connectors 3, equipped with a bottom (defined by the inner wall, 9a and 10a respectively) and with an opposite open end onto which a respective cover (defined by the inner wall, 9b and 10b respectively) is applied when closing, for example by pressure or by snap-fastening.
  • the hinged connection means 6 are connected to the articulated portions 9 and 10 so that the rotation axis X-X is parallel to the axis Y-Y of the tubular element of each electrical connector 3.
  • the hinged connection means 6 are made in a single piece with the articulated portions 9 and 10, being defined by appendages 7 projecting from the side of the articulated portions and having the end portion configured so as to define the hinge pin or the pivot of a hinge. More specifically, the articulated portions 9 and 10 comprise opposite matching appendages suitable for engaging with one another since they are configured so as to define the hinge pin and the pivot of a hinge, respectively.
  • the two articulated portions 9 and 10 of the body 2 comprise matching engagement means 8 suitable for engaging with one another to keep said two articulated portions joined together in the aforementioned overlapped configuration of the insulating body 2.
  • the aforementioned matching engagement means 8 are in the form of projections projecting from the side of the articulated portions 9 and 10 opposite the side at which the hinged connection means 6 are positioned.
  • the aforementioned matching engagement means 8 of the two articulated portions 9 and 10 make a reversible snap engagement with each other suitable for keeping the two articulated portions 9 and 10 of the body 2 joined brought together in the aforementioned closed configuration (cf. figure 1 )
  • the aforementioned clamping means 4 are positioned so as to be able to be actuated from the same side of said body when said body is in said extended configuration.
  • the screw of the clamping means 4 associated with the electrical connectors 3 can be actuated with the tip S of the screwdriver by acting from the outer side 9b and 10b of the two articulated portions 9 and 10.
  • this makes it possible to act to clamp on the aforementioned clamping means 4 by acting from outside always from the same side of the body 2, without therefore needing to turn the terminal board by 180° to be able to actuate all of the clamping means 4.
  • the matching engagement means 8 which are brought by the two articulated portions 9 and 10 interact with one another, determining reversible snap-locking of the two articulated portions such as to prevent the insulating body 2 from going back into the aforementioned extended configuration (cf. figure 2 and from 4 to 7).
  • the terminal board for the electrical interconnection of electrical conductors makes it possible to satisfy the aforementioned requirement and at the same time to overcome the drawbacks referred to in the introductory part of the present description with reference to the prior art.
  • the terminal board according to the invention it is possible to carry out the wiring operation of the electrical conductors while it is in the extended configuration, so as to be able to easily act on the clamping means always from the same side of the body of the terminal boards and, once the wiring operation has ended, it is possible to articulate the parts of the body of the terminal board so as to take the body thereof in the overlapped configuration that is less problematic than the extended configuration in terms of the bulk of the terminal board.
  • Another advantage of the terminal board according to the invention is the unusual possibility to have structural simplicity thereof.
  • clamping means or the matching engagement means can also take up a different configuration or can be positioned differently with respect to what has been described above.
