Definitions

  • the present invention relates to a pluggable electrical connector, of the type comprising a generally U-shaped connection cage delimited by two metal cheeks between which a pin, for example a pin, can be inserted, by the top opening of this U blade or a cylindrical fuse cartridge, intended to control or cut the electrical supply of a circuit or an apparatus, including a meter, and at least one contact cage in the form of an enclosure in which is placed and maintained an electrically conductive cable, for powering the circuit or the device.
  • plug-in electrical connectors which are fixed on a plate, on an electrical panel or inside a box, in order to control or cut on demand the electrical supply of circuits or of devices from one or more electrically conductive cables which are held in the or in the contact cages of the connector by means of one or as many studs, the end of which either rests directly on the conductive core of a bare cable, or is perforated with insulation and in this case rests on the core after having crossed the insulating sheath, and whose rod or head is electrically linked to the cheeks of the cage connection.
  • Such connectors have been designed to operate with different types of pins, and more particularly with blade-shaped pins, also known as “knife” or cylindrical pins, with fusible cartridges.
  • the plug-in electrical connectors made of folded sheet metal are in theory with an unlimited number of contact cages, each receiving and retaining a cable carrying the same phase.
  • the connectors in question are limited to a contact cage and, consequently, to a supply by a single cable.
  • the known connectors are used with conductors whose cross section can vary between approximately 1.5 mm 2 and 240 mm 2 . With insulation perforation, the known connectors are used with conductors whose section can vary between approximately 16 mm 2 and 150 MM 2 .
  • a connector of the aforementioned type, obtained by successive bending of a metal sheet, has been shown in its construction with insulation perforation, in Figure 1 of the accompanying drawings, so as to better understand the criticisms which will follow concerning this type of material.
  • the connectors currently on the market are of limited use at relatively low amperages, of the order of a hundred amps. For example, when referring to French standards, we know that the temperature of the connector should never exceed 120 ° C.
  • the stud carries a piece in the form of a bowl crimped by its bottom at the end of said stud, the edges of said bowl being provided with a plurality of teeth each capable of perforating the cable insulation sheath; similarly, the bottom of the contact cage is punctured from the outside, by means of a punch, so that it also has teeth, prominent inside the cage.
  • the connector fixing support is formed by two lateral tabs which extend the bottom of the connection cage and / or the bottom of the contact cage; the mechanical weakness of such a fixing means is also obvious when one remembers that the sheet which is used for the construction of the connector is necessarily thin.
  • the connector corresponding to the construction shown in Figure 1 is in practice limited to a supply by a single cable because, by construction, that is to say by bending, it is extremely difficult to provide a second cage. contact beyond the first cage.
  • the present invention overcomes all the aforementioned drawbacks and, to this end, it provides the production of a plug-in electrical connector, which, all at the same time: is of an easy production; is of lower manufacturing cost; allows the use of a metal as good conductor as copper or brass, but less expensive than these materials; is mechanically extremely resistant, without limit as to its thickness and without zone of weakness; consequently suitable for very large amperages since from now on the thickness limit no longer intervenes; suitable for feeding from several cables carrying the same phase, insofar as said connector can include a plurality of contact cages without losing its rigidity or its quality as regards the contact between the pin and the cheeks which delimit the connection cage; and finally easily adapts, by a simple manual adjustment, to spindles, knives or cylindrical cartridges, of different widths.
  • the connector object of the present invention is partly implemented according to a technique applied in neighboring fields, such as that of branch connectors for power lines and that of connectors intended to equip batteries associated with combustion engines. internal.
  • each sectioned element comprises housings each intended to receive a conductor, either the live line, or a branched conductor.
  • connectors for batteries from elements also cut in a metal profile obtained by extrusion, profile which, before the cutting operation, is pierced with orifices perpendicular to the direction of extrusion such that they each form on the subsequently cut element a connection cage orthogonal to a contact cage formed during the extrusion and consequently parallel to the direction of said extrusion.
  • the present invention therefore has for first object a plug-in electrical connector of the type comprising: a) a generally U-shaped connection cage delimited by two metal cheeks between which can be inserted, by the upper opening of this U, a pin , for example a blade or a cylindrical fuse cartridge intended to control or cut the electrical supply of a circuit or an appliance, b) at least one contact cage in the form of an enclosure in which is placed and maintained an electrically conductive cable, for supplying the circuit or apparatus, and c) a central wall common to the connection cage and to at least one contact cage, said connector being produced from a sectional element of metal profile obtained by extrusion, and being characterized in that one of the wings of the U-shaped connection cage is internally doubled by an additional wing which forms one of the two cheeks, a spring being placed between said wing and this jo eu, and in that the common central wall is constituted by the wing of the connection cage other than that which is doubled by the additional wing.
  • This first embodiment of the connector according to the invention made accordingly into its final form at the time of its manufacture by extrusion, immediately shows the advantages obtained in terms of improving the mechanical characteristics, the non-deformability of the profile, the quality of the contact between the pin and the cheeks which border the connection cage, and the possibility of admitting henceforth unlimited amperages since, by definition, the thickness of the extruded metal profile is conceived without upper limit.
  • the extruded metal profile is, in cross section, such that its common central wall separates the two cages by type, on the one hand the connection cage and on the other hand the contiguous contact cage or cages each of which has the form of an enclosure, the wall of at least one of which is formed by said common central wall and of which another wall of each of them can then be pierced with a transverse orifice allowing passage and depth adjustment a stud.
  • the contact cage or all the contact cages joined together in a block are arranged next to the connection cage, the first contact cage of each line having in common with the connection cage the common central wall.
  • the connector according to the invention avoids electrical losses and guarantees its characteristics of excellent mechanical strength and non-deformability at any point whatsoever.
  • connection cage and the contact cage (s) may have the same dimension in the direction of extrusion of the metal profile, perpendicular to its cross section.
  • any electrical connector constitutes the arrival of the general cable, or an auxiliary power cable, and the departure of the fuse which will have to be used later by the installer responsible for ensuring current distribution to the meter placed downstream of the connector.
  • connection conditions which require the positioning of the fuse and of the electrical supply cable on the same side of the connector, normal use of a connector with a single contact cage is no longer possible, and it It is then advisable to have recourse: either to a curvature of the cable, which is always difficult in reduced volumes (the cable is generally a solid aluminum cable of 35 mm 2 of section, that is to say approximately 6.7 mm in diameter, without counting the insulating sheath); either the use of a flexible intermediate nozzle, which, if it facilitates the implementation, on the other hand adds an additional electrical contact detrimental to the quality of the connection; or again with the use of a connector with multiple contact cages in which it is the extreme cage, the furthest from the connection cage, which receives the cable.
  • the present invention therefore has as a second object a plug-in electrical connector which overcomes the last aforementioned drawback and which, for this purpose, is constructed like the connector defined in the preamble of claim 1 and is characterized in that one of the wings of the U-shaped connection cage is internally doubled by an additional wing which forms one of the two cheeks, a spring being placed between said wing and this cheek, and in that the central wall common to the connection cage and to the cage contact is formed by the bottom wall of the U of the connection cage.
  • connection cage below the connection cage (more precisely below the bottom of its U-shaped profile) considerably reduces the front dimensions of the connector (division by almost 3 by relative to a connector with a row of several contact cages on the side of the connection cage as shown by way of example in FIGS. 6 and 7 of the main patent), which thus makes it possible to make four-pole connections in reduced volumes fully compatible with current standards in force.
  • this second construction in which the contact cage is pierced with a transverse orifice allowing the passage and the depth adjustment of a stud whose end rests on the conductive core of the cable and whose rod or head is electrically linked to the cheeks of the connection cage, it is provided that, in the direction of extrusion of the metal profile, perpendicular to its cross section, the contact cage has a larger dimension than the connection cage, the central wall thus extending projecting beyond this connection cage, and that it is in this projecting part of the central wall that the orifice receiving the stud is drilled .
  • said dimension of the contact cage is of the order of magnitude twice that of the connection cage.
  • the contact cage may constitute a solid mass which is traversed, in the direction of extrusion of the metal profile, by a cylindrical passage of diameter substantially equal to that of the end piece. a flexible conductive cable, said end piece being crimped in this passage under and in constant electrical connection with the cheeks of the connection cage.
  • a second cylindrical passage can be provided, in the same direction, in which the end piece of a second flexible conductive cable is crimped.
  • the connector thus equipped with one or two flexible cables, called a “whip connector”, can be used in particular as a departure from a single-pole base intended to receive knife fuses, each flexible cable making the connection to a material located in downstream, usually a counter.
  • a connector of this type can therefore be placed upstream of a counter and downstream of a connector meeting the definitions given for the first or the second variant embodiment, so for example that it will be visible in FIG. 12.
  • the two cheeks of the connection cage can be slightly convergent towards the bottom of the U.
  • the orifice allowing the passage and the depth adjustment of the stud is pierced on one of the walls of the contact cage which is therefore indeed a non-deformable enclosure, instead of being pierced in a nut attached between two walls of said contact cage as is done in the current technique.
  • the hole drilled in the wall of the contact cage is therefore tapped using the same thread as that existing on the stud rod.
  • the wall of the contact cage opposite to that pierced with the orifice for the passage of the stud is provided with longitudinal teeth, obtained during extrusion, and the end of the stem of the stud receives a counter plate also provided with teeth which extend longitudinally, that is to say in the direction of the electric power cable.
  • This construction is particularly advantageous when it is to provide a connector with insulation perforation.
  • the perforation is more easily achieved using this multiplicity of teeth and in addition the electrical contact between the conductor on the one hand and the connector and / or its stud on the other hand is extremely satisfactory since it defined according to several contact lines defined by as many tops of teeth provided in the bottom of the contact cage and on the counter-plate crimped at the end of the stud rod.
  • the connector in its three variant embodiments may include a foot with a straight T-shaped section, the head of which is slightly convex.
  • This construction allows an improved fixing on a plate, and more particularly a slightly oscillating fixing which allows to ensure a perfect alignment between the grooves of several connectors intended to receive a common pin, whether it is knife or cylinder.
  • each connector offered by the invention has no upper limit as far as tolerable amperage is concerned, since the material thickness limit no longer applies: we can extrude a profile as thick as we want .
  • the stud and tapping system in a wall of the connector which replaces the nut of the prior art with folded sheet, is of material: there is therefore no more possible breakage, even when the tightening torque is very important.
  • the longitudinal teeth which replace the puncture are made of material: there is therefore no longer any area of fragility.

  • the bottom 17c of the contact cage 16 is punched from the outside so as to form a puncture 28 as well as a plurality of teeth 28 ' prominent inside the contact cage and able to pass through the insulation sheath of the supply conductor to be maintained.
  • a punctured 28 and such teeth 28 ′ are shown in FIG. 1 in the bottom of a second contact cage (shown in phantom in 30) obtained by folding at the end of the first contact cage 16.
  • Each connector proper is obtained by extruding metal through a shaped die to deliver a profile, the section of which advantageously corresponds to the shape shown in Figures 2, 3 and 5 to 10 for the first embodiment in cage (s) of contact placed next to the connection cage, in Figures 11 to 15 for the second embodiment, contact cage (s) arranged under the connection cage and in Figures 16 and 17 for the third embodiment in which the contact cage constitutes a solid mass disposed under the connection cage.
