Definitions

  • connection terminals of the kind comprising, in a body of insulating material, at least one connection pad, which, to receive at least one electrical conductor, is perforated with a bore, in practice cylindrical, and which, for the tightening of this electrical conductor, is equipped with a clamping screw transversely to this bore.
  • connection terminals commonly known as “single entry"
  • body of insulating material forms a blind housing for receiving the connection pad, so that when two electrical conductors must be connected to each other, these two electrical conductors must be engaged on the same side in this connection pad, instead of being each respectively engaged on one side and on the other as is the case in connection terminals with two inputs.
  • connection pad greater thickness on the side of the clamping screw only on the side opposite it, so that, while promoting an optimization of the total amount of material used for the constitution of this connection pad, the clamping screw is given a grip sufficient tightening in it.
  • connection stud best connects continuously with the body of insulating material in which it is located, and, in the case of a connection terminal with single input, the presence of such a chamfer is all the more desirable that, relating to two electrical conductors acting on the same side, the corresponding engagement difficulties are found to be singularly increased.
  • connection pad can be indifferently placed on one side or the other in the body of insulating material which it must equip, and to thus facilitate the assembly of the assembly, it is on the contrary desirable that this connection pad is symmetrical.
  • the present invention generally relates to a provision which makes it possible to satisfy in a relatively simple manner these two apparently contradictory requirements, and which, although more particularly intended to be applied to a connection terminal with single input, can quite as well be implemented in a connection terminal with two inputs.
  • connection terminal of the kind comprising, in a body of insulating material, at least one connection pad, which, to receive at least one electrical conductor, is perforated with a cylindrical bore, at least on one side, the outlet to the outside is flared by a chamfer, and which, for the tightening of this electrical conductor, is equipped with a clamping screw transversely relative to its bore,
  • this connection terminal being generally characterized in that the outlet outside the bore of the connection stud is flared by two separate chamfers, one extending from the side of the clamping screw, the other extending on the side opposite it.
  • connection stud symmetrical with respect to the transverse plane passing through the axis of its clamping screw.
  • connection terminal 10 with a single input 11, that is to say to a connection terminal 10 in which two electrical conductors 12 to be connected to each other must be engaged on the same side.
  • the electrical conductors 12 are both multi-strand electrical conductors, that is to say electrical conductors whose conductive core 13, duly stripped at its end, is formed of '' a multiplicity of metallic strands.
  • connection terminal 10 comprises, overall, in a body made of insulating material 14, at least one connection pad 15, which, to receive at least one electrical conductor 12, and in practice two in the form of embodiment shown, is perforated longitudinally with a bore 16, cylindrical and smooth, and which, for clamping the electrical conductor (s) 12, is equipped with a clamping screw 18 transversely to this bore 16.
  • connection pad 15 is provided.
  • connection pad 15 is preferably made of conductive material, and, for example, of metal.
  • the bore 16 of the connection pad 15 has a cross section of circular outline, and it opens axially at both of its ends.
  • This axis A1 is shown in broken lines in FIGS. 2, 6 and 8, and it is shown diagrammatically by its trace in FIGS. 5 and 7.
  • A2 perpendicular to A1 be the axis of the tightening screw 18, and, therefore, of the hole 19, tapped, that presents transversely the connection pad 15 for cooperation therewith.
  • This axis A2 is shown in broken lines in FIGS. 2, 6 and 8, and it is shown diagrammatically by its trace in FIG. 3.
  • the front faces 20 of the connection pad 15, on which the hole 16 opens at one and the other of its ends are straight, and, parallel to each other, they extend perpendicular to the axis A1 of this bore 16.
  • the outlet outside this bore 16 is flared, internally, by a chamfer 22A, the concavity of which is facing outward.
  • the outlet outside the bore 16 of the connection pad 15 on a front face 20 of the latter is flared by two distinct chamfers 22A, 22B, one, in this case the chamfer 22B, which extends from the side of the clamping screw 18, and the other, in this case the chamfer 22A, which extends from the side opposite the latter.
  • angles of inclination I A , I B of the chamfers 22A, 22B on the generatrices of the bore 16, and, therefore, on the axis A1 thereof are different.
  • angles of inclination I A , I B are different from each other.
  • the chamfer 22B which extends on the side of the clamping screw 18, and therefore on the side of the tapped hole 19, is that of the greatest angle of inclination
  • the chamfer 22A which extends on the side opposite to the clamping screw 18 is that of the smallest angle of inclination.
  • the thickness E B of the connection pad 15 on the side of the clamping screw 18, and therefore on the side of its tapped hole 19, is greater than that E A on the side opposite to this clamping screw 18.
  • the chamfer 22A with the smallest angle of inclination is a frustoconical chamfer of the bore 16, and therefore of axis coincident with the axis A1 thereof, and, jointly, the chamfer 22B of angle the highest inclination is a frustoconical chamfer of axis A3 different from that A1 of the hole 16 while being parallel thereto.
  • the chamfer 22B with the highest angle of inclination is offset from the bore 16.
  • Its axis A3 is shown in broken lines in FIGS. 6 and 8, and it is shown diagrammatically by its trace in FIGS. 5 and 7.
  • this axis A3 extends between the axis A1 of the bore 16 and the clamping screw 18.
  • the value of the angle of inclination I B of the chamfer 22B of the highest angle of inclination is between 1.3 and 2.2 times that of the angle of inclination I A of the chamfer 22A d 'lowest angle of inclination.
  • the angle of inclination I A of chamfer 22A with the lowest inclination angle is around 30 °, while the inclination angle I B with the chamfer 22B with the highest inclination angle is around 45 ° .
  • the two chamfers 22A, 22B each extend in increasing fashion around the bore 16, each bordering it locally, over more than 180 ° for one of them, in this case the chamfer 22A d 'lowest angle of inclination, on less than 180 ° for the other, in this case the chamfer 22B of the highest angle of inclination, and, at their ends, these two chamfers 22A, 22B overlap one the other along two edges 23 which each go from a point on the corresponding front face 20 of the connection pad 15 to a point on the internal surface 25 of its bore 16.
  • the value of the angle of inclination I A of the chamfer 22A of the smallest angle of inclination is for example of the order of 30 °, as previously, however that the value of the angle of inclination I B of the chamfer 22B with the highest angle of inclination is for example of the order of 60 °.
  • the two chamfers 22A, 22B then overlap each other along a single edge 24, which goes from one to the other of two points of the corresponding front face 20 of the connection pad 15 while remaining at away from the internal surface 25 of the bore 16 thereof.
  • the chamfer 22A of the lowest inclination angle continuously belts the bore 16, while the chamfer 22B of the highest inclination angle remains away from it.
  • the chamfer 22A with the smallest inclination angle is executed first, and the chamfer 22B with the highest inclination angle results from a subsequent resumption of machining.
  • angles of inclination I A , I B of the two chamfers 22A, 22B on the generatrices of the bore 16 are equal, and, more precisely, are equal to each other.
  • the chamfer 22A which extends on the side opposite to the clamping screw 18, and, therefore, on the side opposite to the hole 19, is a frustoconical chamfer of the bore 16
  • the chamfer 22B which extends on the side of the clamping screw 18, and, therefore, on the side of the hole 19, is a frustoconical chamfer, which is offset from the previous one and whose axis A3, parallel to the axis A1 of the bore 16, extends between this axis A1 and the clamping screw 18, and therefore between this axis A1 and the hole 19.
  • these two chamfers 22A, 22B overlap each other along two edges 23 which each go from one point of the front surface 20 corresponding to the connection pad 15 at a point on the internal surface 25 of its bore 16.
  • the part of the connection pad 15 situated on the side of the clamping screw 18, and therefore of the tapped hole 19, has, overall, a parallelepiped external contour, while the part diametrically opposite to the previous one has, on the outside, a generally cylindrical outline.
