Definitions

  • the invention relates to insulation displacement connection members, that is to say, male or female connection members having a U-shaped body with a core and wings, the latter being cut out to present bars whose lateral edges are extended by returns forming between them slots which widen towards the opening.
  • the conductor at the end of which an insulation displacement connection member must be mounted must necessarily have dimensions corresponding to the width of the slots.
  • One of the aims of the present invention is to produce a male or female connection member provided with means of connection to an electrical conductor with displacement of insulator making it possible to receive conductors having different section dimensions.
  • the member is of the type produced from a blank of good electrically conductive material cut and folded into a U to present a core and two wings, said member comprising at one end a male tongue or a female element and at the other end of the means for connection to an electrical conductor, said means being of the type known as "displacement of insulation" and having two bars whose lateral edges are extended by returns bent one opposite on the other to provide two slots whose free edges widen and are sharp, said member being characterized in that the wings are cut to present between the tongue or the female element and the means of connection to a electrical conductor, two legs folded along one of their longitudinal edges to each present a return, the returns being opposite each other to form a slot.
  • the conductor will be notched at three points and will bear against the edges of three slots, which ensures a good electrical connection with conductors having different sections.
  • the free ends of the returns can be cut to form a cutting end and flared from the slot.
  • the width of the slots of the different insulation displacement connecting means may be different.
  • Another object of the invention is to remedy this drawback.
  • one of the bars has a wide opening. Thanks to this arrangement, the excess insulation flows through the opening, which prevents deformation of the organ.
  • Another object of the invention is to overcome this drawback.
  • the bar opposite to that provided with the wide opening comprises two notches forming between them a strip.
  • the strip can thus be folded over the conductor and prevent any untimely withdrawal of the latter.
  • connection member is cut from a metal blank having two different thicknesses, the tongue being cut from the part having the greatest thickness.
  • the female element is formed, on the one hand, by an extension of the core and, on the other hand, by two extensions of the wings which are folded to extend above the core, parts being cut between the corresponding edges of the extensions of the wings and of the extension of the core , these parts being folded one opposite the other to form stops.
  • the female element can be constituted by a tubular element.
  • the member according to the invention finds a particularly advantageous application for the use of conductors in the form of insulating plies in the thickness of which are embedded, in parallel, conductive wires or strands.
  • the plies must be crossed by bars and, for this purpose, the free edge of the bar having the opening is sharp.
  • the free edge of the strip is sharp.
  • Figure 1 is a perspective view of a male member according to the invention, the latter being shown unfinished to facilitate understanding.
  • Figure 2 is a perspective view of the body of Figure 1 completed.
  • Figure 3 is a perspective view of a female member, according to the invention, it being shown unfinished for better understanding.
  • Figure 4 is a perspective view of the female member of Figure 3 completed.
  • Figure 5 is a perspective view of another variant of the invention.
  • the member of FIGS. 1 and 2 is more particularly intended for use with electrical conductors in the form of a sheet of insulating material having in parallel embedded wires or strands of conductors, in copper for example, the wires may have different sections.
  • FIGS. 1 and 2 a male electrical connection member has been shown produced from a blank of material which is good conductor of electricity and one part of which has a thickness greater than the other, the part, the thickest allowing to make a rigid tongue 1.
  • an opening 2 is made for fixing the male member in a connection box made of insulating material, the blank being folded into a U to present two wings 3 and 4 and a core 6.
  • the tab 5 is folded to present a return 7 extending opposite a corresponding return 21 of the tab 8, these returns determining between them a slot 30.
  • the free end of the tab 5 is slightly sharpened, while the upper edge of the return 7 is cut in the form of a bevel 9 with a slight sharpening.
  • the free end of the tab 8 is also slightly sharpened and the upper edge of the return 21 is cut in the form of a bevel 10 with a slight sharpening. An insulation displacement fixing device is thus produced.
  • the bar 11 is folded into a U to present two returns 15 and 18 and a strip 12, the latter being slightly folded towards the inside of the U along a line 14 and having an end 13 slightly sharpened.
  • the strip 12 is separated from the cheeks 15 and 18 by notches 28 and 29.
  • the return 15 has a slightly sharpened beveled portion 17, and the return 18 has a slightly sharpened beveled portion 19.
  • the bar 22 is pierced with a large opening 27 and is folded in a U to present a return 23 extending opposite the free edge of the return 15 and a return 24 extending opposite the free edge of the return 18, the ends upper returns 23 and 24 being terminated by slightly sharpened beveled portions 25 and 26 respectively.
  • the return 23 and the return 15 determine a slot 16 while the returns 18 and 24 provide a slot 20.
  • a second device for fixing a conductor with insulation displacement is thus produced.
  • the width of the slots 16, 20 and 30 can be the same or different.
  • the member of FIGS. 1 and 2 is intended more particularly to be used with conductors in the form of a sheet of insulating material in which several conductive wires or strands are embedded.
  • the male member is held in a tool or in a housing, while a tool pushes the conductor so that the corresponding strand comes to be inserted between the slots 16, 20 and 30, the end of the strip 12 as well as the end of the strip 22 and the ends of the tabs 5 and 8 make it possible to cut the insulation of the sheet, the edges of the insulation surrounding the strand being cut by the cut sides 9, 10, 17, 19, 25 and 26 so that the strand is stripped and not cut is housed in the slots 16, 20, 30 to provide the electrical connection.
  • the strip 12 is then folded over the insulation of the strand, this folding being facilitated by the slight inclination of the free end of said strip 12.
  • Figures 3 and 4 show in perspective an alternative embodiment applied to a female connection member.
  • the end of this female member intended to receive the electrical conductor is identical to that provided for the male member of Figures 1 and 2 and will therefore not be described here in detail.
  • FIGS. 3 and 4 the same references have been given to designate the members corresponding to those of said FIGS. 1 and 2 as those used in these latter figures but assigned the letter "a".
  • the female member is made from a metal blank that is a good conductor of electricity, cut and folded to affect a U-shaped section with a core 36 and two wings 37 and 38.
  • the end intended to receive the conductor has tabs 5 a , 8 a with returns 7 a , 21 a sparing a slot 30 a , a strip 11 a with returns 15 a , 18 a and a strip 12 a , and a strip 22 a with returns 23 a and 24 a and an opening 27 a .
  • the member at its end opposite to that provided with the tabs 5 a , 8 a , is shaped to present an elastic clamp 40 intended to grip a male member, for example, a tongue such as the tongue 1.
  • the core 36 is provided with an extension 41 terminated by a curved portion 42, while the wing 37 is provided with an extension 43 which is folded above the core 36 and whose free end is arched so to form with the end 42, a flared opening.
  • the wing 38 also has an extension 44 folded so that its edge comes to cooperate with the corresponding edge of the extension 43.
  • the free end of the extension 44 is also arched and the width of each extension 43 and 44 is equal to half the width of the extension 41.
  • a first cut part 45 is provided between the corresponding edges of the extensions 41 and 43 and a second cut part 46 between the corresponding edges of the extensions 41 and 44, these parts 45 and 46 being folded at right angles towards the interior of the member so as to constitute, on the one hand, a stop for the driver and the male member and, on the other hand, a stiffener to maintain the spacing between the bases of the extensions.
  • the free ends of the extensions 41, 43 and 44 may have stampings 48 cooperating with one another in order to grip a male tongue against contact points.
  • Figure 5 shows in perspective an alternative embodiment of a female connection member.
  • the same references assigned the letter "b" have been used to designate the members corresponding to those of the preceding figures.
  • the female organ is produced from a metal blank which is a good conductor of electricity, cut and folded to affect a U-shaped section with a core 50 and two wings 51 and 52.
  • the end of the member intended to receive the conductor is arranged in the same way as the members of the preceding figures and has slots 30 b , 20 b and 16 b , while the other end is terminated by a tubular element 53 with circular section intended to receive a male member of corresponding section.
