Definitions

  • connection devices commonly referred to as substation fittings.
  • each fitting is composed of opposite jaws formed by a molded metal body, comprising one or two gutters secured to a fixing element, and molded metal flanges, these elements being tightened on the conductor by bolts passing through the body and the flanges.
  • this method of manufacture requires that a mold be made for the body of each type of fitting, since the flanges can be used for different types of fittings. It follows that this manufacturing method is only interesting 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 conditions of connection or fixing, a new mold must be made, which leads to a heavy investment and long manufacturing times.
  • One of the objects of the invention is to provide a modular connection device which can very quickly adapt to the needs of the request by requiring no new investment in the mold.
  • 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 obtained by cutting a length of an extruded metal profile, comprising at least one longitudinal and axial groove, constituting gutter, of shape and dimensions capable of cooperating with clamping of the conductor, while the connection between two jaws of a pair of opposite jaws is ensured by screws whose threaded ends are screwed into tapped holes made in one of the jaws and whose bodies pass through bores made in the 'other jaw, these threads and bores being distributed with a longitudinal pitch identical to their transverse pitch.
  • 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 complementary fixing and / or electrical connection elements making it possible to meet connection needs, and this without the need for costly investments.
  • 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 capable of spreading them apart.
  • This structure separates the jaws of each modular element when the latter is at rest, and thus facilitates connection maneuvers, since the operator only has to be concerned in this phase with engaging the conductors between the front jaws to tighten them.
  • the modular elements are fixed on fixing plates, rectilinear, bent or counter-bent, or on fixing bases.
  • the device according to the invention is essentially composed of at least one pair A of jaws 2a-2b linked to one another by screws 3. Each jaw is cut to the desired length from a metal profile, made of alloy d aluminum, 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 on 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 the 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 of making transverse threads 6.
  • the other jaw 2b is subjected to a drilling operation making transverse bores 7.
  • the longitudinal pitch PL of the threads and bores is equal to their transverse pitch 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 spacer spring 8 disposed around them and bearing on the bottom of the grooves 5.
  • the ends of the springs 8 are positioned transversely by the edges 5b of the lateral grooves 5.
  • a pair A of jaws forms a modular element which can be associated, depending on the requirements of the installation, either with a connection pad B to form a connection terminal, as shown in FIGS. 1 to 3, or with a base C, as shown in FIG. 4. It can also be associated by a connecting plate 13 with at least one other pair of jaws to form a connection device between two conductors, as shown in FIGS. 5 to 7. It is obvious that, as required, the jaws can be more or less long and be linked to each other by four screws, six screws, or eight screws, arranged in the modular steps PL and PT.
  • the two jaws 2a-2b are associated with a fixing plate 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. It will be noted that the plate 9 can also be arranged with its longitudinal axis perpendicular to that of the pair of jaws, and this without there being any need to make any additional investment.
  • the plate 9 can comprise, in its part not linked to the pair of jaws, a bent sector which, as required, can be arranged longitudinally or transversely to these jaws.
  • FIG. 3 shows that the fixing plate can also be bent at 9a and counter-bent at 9b, in its part arranged outside of its fixing zone with the jaws.
  • the same pair of jaws A can form a leg connection by association with a base C comprising a threaded end 10 screwed 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 with several other elements to form a multiple connection.
  • each modular element is made integral with the others by a common fixing plate to which it is itself fixed by its screws 3 ensuring the clamping of the jaws on the conductor.
  • FIG. 6 shows a simplified version, for end-to-end connection of the two identical or diameter conductors 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 forms a connecting element 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 considerably reduce the time necessary for the production of non-standard substation fittings and thus to meet needs, by series, small or large.
