Definitions

  • connection devices commonly referred to as post fittings.
  • each fitting is made up of opposing jaws formed by a molded metal body, comprising one or two gutters integral with a fixing element, and molded metal flanges, these elements being tightened on the conductor by bolts passing through the body and the flanges.
  • this manufacturing method requires make a mold for the body of each type of fitting, since the flanges can be used for different types of fittings.
  • this method of manufacture is not interesting only for large series and is totally unsuitable for small series, since for any new type of fitting different from those existing by variations in shapes, dimensions or connection or fixing conditions, it you have to make a new mold, which leads to a heavy investment and lead times long manufacturing.
  • connection device modular that can very quickly adapt to the needs of the demand by requiring no new mold investment.
  • connection mode by bolts between body and flanges, connection requiring complete disassembly before installation and requiring numerous manipulations to replace the bolts, their nuts and washers after mounting the body and flanges on the conductors.
  • Another object of the invention is to provide a connection device simplifying its installation while reducing the manipulations necessary for its assembly.
  • each of the jaws is the result of cutting a desired length from an extruded metal profile, comprising at least one longitudinal and axial groove, constituting gutter, of shape and dimensions able to cooperate in clamping the conductor, while the connection between two jaws of a pair of opposite jaws is secured by screws whose ends threaded are screwed into threaded holes made in one of the jaws and whose bodies pass through bores in the other jaw, these threads and bores being distributed with a longitudinal pitch identical to their transverse pitch so that each pair of opposite jaws constitutes a modular element.
  • each pair of jaws forms a modular element which can be assembled with another identical modular element, with its longitudinal axis arranged in the extension of that of the other element or perpendicular to this axis.
  • Each modular element or several elements can be combined with various elements additional fixing and / or electrical connection to meet the connection needs, without the need to make investments expensive.
  • At least two of the connecting screws between two jaws of the same pair of jaws are associated with a helical spring surrounding them and able to remove them.
  • This structure spreads the jaws of each modular element when this the latter is at rest, and thus facilitates the connection maneuvers, since the operator only has to worry about engaging the conductors between the front jaws in this phase to tighten them.
  • the modular elements are fixed on plates of fixing, rectilinear, bent or counter-bent, or on fixing legs.
  • the device according to the invention is essentially composed of at least one pair A of jaws 2a-2b linked to each other by screws 3. Each jaw is cut to size desired length in a metal profile, aluminum alloy, bronze or copper, extruded or spun, that is to say formed by passing through a die.
  • the profile comprises, emerging from one of its large faces, a longitudinal and axial groove 4, bordered by each side by two lateral grooves 5, parallel to it.
  • the axial groove 4 has, in the embodiment shown, a semi-circular section, but it can also have a flat bottom and straight edges, when it is intended to clamp conductors of rectangular section.
  • the two lateral grooves each have a flat bottom 5a bordered by two straight edges 5b.
  • one of the jaws is subjected to a machining operation consisting in making transverse threads 6.
  • the other jaw 2b is subjected to a drilling operation making bores transverse 7.
  • the longitudinal pitch PL of the threads and bores is equal at their transverse step PT.
  • At least two of the screws 3 ensuring the connection of the two jaws 2a and 2b, and more particularly two opposite screws, are each associated with a spring spacer 8 disposed around them and bearing on the bottom of the grooves 5. It will be noted that the ends of the springs 8 are positioned transversely by the edges 5b of the grooves side 5.
  • a pair A of jaws forms a modular element which can be associated, depending on the needs of the installation, either with a connection area B to form a connection terminal, as shown in Figures 1 to 3, i.e. at a base C, as shown in figure 4. It can also be combined by a plate of connection 13 to at least one other pair of jaws to form a device for connection between two conductors, as shown in Figures 5 to 7. It is obvious that, depending on requirements, the jaws can be longer or shorter and can be linked to each other the other by four screws, six screws, or eight screws, arranged in modular steps PL and PT.
  • the two jaws 2a-2b are associated with a plate of fixing 9 which is rectilinear and arranged, with its longitudinal axis, parallel to that of the gutter formed by the two axial grooves 4 of the two jaws.
  • the plate 9 can also be arranged with its longitudinal axis perpendicular to that of the pair jaws, and there is no need to make any investment additional.
  • the plate 9 may include, in its part not linked to the pair of jaws, a angled sector which, as required, can be arranged longitudinally or transversely to these jaws.
  • Figure 3 shows that the fixing plate can also be bent at 9a and counter-bent at 9b, in its part disposed outside of its attachment zone with the jaws.
  • the same pair of jaws A can form a foot connection by association with a base C having a threaded end 10 screwing into a threaded hole 12 formed transversely in one of the two jaws, and for example in that 2b.
  • each modular element consisting of a pair of jaws A are connected to each other by a common connecting plate 13.
  • these elements are arranged with their longitudinal axes at 90 °, but they can of course be arranged with their co-axial axes.
  • these two elements can be combined with a third element to form a "T" connection, or several other elements to form a multiple connection.
  • each modular element is made integral with the others by a fixing plate common to which it is itself fixed by its screws 3 ensuring the clamping of the jaws on the driver.
  • Figure 6 shows a simplified version for end-to-end connection of two identical conductors or of diameter corresponding to the capacity of the jaws 2a and 2b, in which a jaw 2c of greater length than the jaws 2a of the two pairs A of jaws, and common to these two pairs of jaws and form element of connection between pairs of jaws.
  • connection device of the type shown in FIG. 5, is connected by its fixing plate 13 to a base 14.
  • This device therefore makes it possible, with a reduced investment, to reduce considerably the time required to make non-standard substation connections and thus to meet the needs, by series, small or large.
