Definitions

  • connection terminals whether they are connection terminals intended to operate in isolation, for example for the connection of one electrical conductor to another, or whether they are of connection terminals which, being an integral part of the casing of any electrical apparatus or apparatus, or duly attached to this casing, are intended for the connection, to this apparatus or electrical apparatus, of the electrical conductor or conductors necessary for serving it.
  • connection terminals which comprise at least one insulation displacement connection member, that is to say a connection member, in metallic practice, locally presenting at least one slot in which the force must be engaged. electrical conductor to be connected.
  • the present invention relates to the case where, to such a connection member, are associated, on the one hand, an operating member, which is mounted movable relative to this connection member, and, on the other hand, a control screw, which is available to the user, and which is capable of acting on this operating member, for the forced engagement of an electrical conductor in the slot of the connection member.
  • the operating member is most often reduced to a simple plate, which is freely traversed by the barrel of the control screw, this barrel meshing with a fixed member, for example with the connection member or a member integral with the latter, beyond this operating member.
  • the control screw carries by its head on the operating member, and, when screwed, it thus makes it possible to move the latter in the direction of the slot of the connection member.
  • the electrical conductor to be connected comes to bear by its conductive core against the lips of the slot of the connection member, which ensures the desired electrical contact, and if, in addition, this electrical conductor is a conductor electric insulated, the lips of this slot ensure by themselves beforehand the local stripping of its conductive core, by shearing of the insulating sheath which surrounds it.
  • the electrical conductor can be disconnected.
  • control screw is capable of acting on the operating member for either of the direction of movement of the latter relative to the slot of the connection member, which facilitates both the connection and disconnection of an electrical conductor.
  • connection terminal being in practice provided for electrical conductors of relatively small cross section suitable for the circulation of relatively small currents, at very low voltage, as is the case for example in telephony or in computer science, the member in this case constitutes a mounted barrel rotary, and, by a head shaped accordingly, it very simply forms by itself the control screw necessary for its rotary control.
  • this arrangement is not normally suitable when the electrical conductor to be connected has a relatively large cross section.
  • the present invention generally relates to a provision which, on the contrary, is suitable even in such a case, and, more precisely, very precisely provided for such a case.
  • connection terminal of the kind comprising at least one insulation displacement connection member, which has locally at least one slot, and with which are associated, on the one hand, an operating member, which is mounted movable relative to the connection member, and, on the other hand, at the disposal of the user, a control screw, which forms a separate part both from the connection member and from the operating member, and which is capable of acting on the operating member for at least one direction of movement of the latter relative to the slot of the connection member
  • this connection terminal being generally characterized in that l actuator generally has a U-shaped configuration, with, each arranged respectively on either side of a middle portion generally parallel to the direction of elongation of the slot of the connection member, two wings one and the other globally perpendicular to this say ction of elongation, and in that, by its barrel, the control screw meshes with any one of these wings.
  • the operating member forms, as it were, in the manner of a jumper, a pocket in which the electrical conductor is inserted during its engagement in the connection terminal.
  • the wing of the actuator furthest from the head of the control screw acts to push on this electrical conductor, on a first side thereof, until it is forced, as desired, to forcefully engage in this slot.
  • control screw For a second direction of action on the control screw, which in practice causes it to be unscrewed, and which corresponds to the disconnection of the electrical conductor, it is the other wing of the operating member, it is that is to say the one closest to the head of the control screw, which acts, in traction, on this electrical conductor, on the side thereof opposite to the previous one, until it releases it, as desired, from the slot of the connecting member.
  • the screw for controlling the connection terminal according to the invention ensures both the connection of an electrical conductor and its disconnection.
  • the slot presented by the connection member is stepped, this slot comprising, successively, at least two sets of V-shaped lips staggered longitudinally relative to one another while being offset transversely one relative to the other.
  • connection terminal according to the invention advantageously allows the connection terminal according to the invention to be used interchangeably, in a relatively wide range, with electrical conductors of different cross sections.
  • the operating member 16 has, overall, a U-shaped configuration, with, each disposed respectively on either side of a middle portion 19 generally parallel to the direction of elongation D of the slot 15 of the connection member 14, two wings 20A, 20B one and the other generally perpendicular to this direction of elongation D, and, by its barrel 22, the control screw 18 meshes with any one of these wings 20A, 20B.
  • connection member 14 comprises, at a distance from one another, generally parallel to one another, at least two slots 15.
  • connection member 14 has, on a square, on the one hand, a first section 23, which, generally planar, extends substantially parallel to the barrel 22 of the control screw 18, and which comprises, opening onto its free edge, the two slots 15, and, on the other hand, a second section 24, also generally planar, which, by a bore 25, is freely traversed by the barrel 22 of the control screw 18 , and on which rests the head 26 thereof.
  • connection member 14 has a third section 27 which, also generally planar, is parallel to the first section 23.
  • connection member 14 therefore also has a U-shaped configuration in the embodiments shown.
  • its third section 27 has a length greater than that of the first section 23.
  • connection member 14 thus formed is in practice metallic.
  • it can be made from any metal strip, by simple cutting and folding thereof.
  • the bore 25 presented by the section 24 is established along the median plane of the assembly.
  • each of these slots 15 is stepped, comprising successively, from its entry 30, and as is better visible for one of them in FIG. 3, two sets of lips in V 31 ', 31 "which, while being staggered longitudinally with respect to each other along the direction of elongation D, are also offset transversely with respect to each other, by being connected to each other by a shoulder 32 generally transverse with respect to this direction of elongation D.
  • the V-shaped lips 31 ', 31 "have different slopes, those closest to the inlet 30, in this case the lips 31', forming an angle between them. A 'greater than that A "formed between them those furthest from this inlet 30, in this case the lips 31' '.
  • each of the slots 15 has a blind bottom 33, rounded in a semicircle, and this is preceded by parallel lips 34.
  • each of the slots 15 ends in a rectilinear section.
  • the wings 20A, 20B of the operating member 16 each extend respectively on either side of the slots 15 of the connection member 14, perpendicular to the direction of elongation D of these slots 15.
  • the wing 20A which is the one furthest from the head 26 of the control screw 18, extends generally outside the internal volume of the connection member 14.
  • the wing 20B which is therefore the one which is closest to the head 26 of the control screw 18, extends inside the internal volume of the connection member 14, between the sections 23 and 27 parallels of it.
  • the barrel 22 of the control screw 18 meshes with the wing 20A of the operating member 16 furthest from its head 26, while, through a bore 35, it freely crosses the wing 20B closest to this head 26.
  • the wing 20A of the operating member 16 has a threaded bore 36.
  • this wing 20A is locally reinforced by a boss 38 which projects on its external face.
  • the wing 20A of the operating member 16 furthest from the head 26 of the control screw 18 has, along its free edge, for action on the electrical conductors 10 to be connected to each other, a square return 40 directed towards the slots 15 of the connection member 14.
  • this return to square 40 extends generally parallel to the section 23 of the connection member 14 having the slots 15, and it is offset with respect to this section 23, perpendicular thereto.
  • this square return 40 extends beyond this section 23 of the connection member 14 relative to the barrel 22 of the control screw 18, by a distance at least equal to the thickness of this section 23, so as not to interfere with it.
  • connection member 14 by itself guides the operating member 16.
  • the operating member 16 is, to do this, in contact, by its middle part 19, of the third section 27 of the connection member 14, on the internal face of the latter, and, by the free edge of its wing 20B closest to the head 26 of the control screw 18, it is jointly in contact with the first section 23 of this connection member 14, on the face internal of it.
  • the operating member 16 can, if desired, be for example made of synthetic material.
  • connection member 14 It can also be metallic, like the connection member 14.
  • the electrical conductors 10 are engaged between the wings 20A, 20B of the operating member 16, according to the arrows F1 in FIG. 1, each being respectively arranged opposite the slots 15 of the connecting member 14.
  • the wing 20A of the operating member 16 furthest from the head 26 of the control screw 18 is then located beyond the electrical conductors 10 relative to the inlet 30 of the slots 15 of the connection member 14, while its wing 20B closest to this head 26 is located below.
  • the operating member 16 is gradually constrained, by its wing 20A, and, more precisely, by the return square 40 thereof, these electrical conductors 10 to engage in the slots 15 of the connection member 16, pushing on them, as shown diagrammatically by the arrow F2 for one of them in FIGS. 5A and 5B.
  • the conductive core 11 can reach the bottom 33 of such a slot 15, as shown in FIG. 8B.
  • connection member 14 is fixed in a housing 42, which, provided for the assembly in a body made of insulating material 43, opens to the outside via at least one inlet 44 suitable for the engagement of one or more electrical conductors 10 in the connection terminal 13, in line with the slot (s) 15 of this connection member 14.
  • the body of insulating material 43 may be specific to the connection terminal 13, or belong to the housing of any apparatus or electrical appliance.
  • the input (s) 44 that it comprises are elongated in a buttonhole parallel to the direction of elongation D of the slot (s) 15 of the connection 14, and therefore parallel to the barrel 22 of the control screw 18.
  • this body of insulating material 43 has, locally, a bore 45.
  • the wing 20A of the operating member 16 furthest from the head 26 of the control screw 18 acts at full surface on the conductor (s) 10, along a generator of those -this, like the wing 20B closest to this head 26, without including, as previously, any square return to do this.
  • the guiding of the operating member 16 in the connection member 14 is done by the single free edge of its wing 20B, its middle part 19 indeed extending in this case to distance from the third section 27 of the connection member 14 while being close to the latter.
