Definitions

  • This invention relates to connecting electrical conductors to other electrical elements and to electrical connections. More particularly, the invention relates to pressure-forming (which will be referred to herein as forging) of ferrules of electrical connectors onto conductors and to forged connections.
  • ferrule connectors i. e., sheet metal portions formed to a U-shaped cross-section applied in a die with sloping sides and bottoms smoothly curved from each side to a central ridge, the wire being gathered in by the legs of the U which scrape the sides of the die and are curled back toward the bottom of the U and the whole being ultimately compressed in the die with the entire periphery being confined so that the ferrule and conductor are forged into a solid mass and the metal flowed in a lengthwise extrusion as well as transversely to fill voids in the cross-section.
  • connection is forged to a more nearly square cross-section.
  • the curled ends at the top of the forged portion are retained as before and the bottom may be convex if desired, although a flat bottom is better (for purposes of this application a convex bottom is treated as though it were flat with the same cross-sectional area; i. e., at the same mean depth below the maximum diameter).
  • the sides however are flat and substantially perpendicular to the bottom.
  • curled ends at the top are keyed to the forged metal of the conductor against outward movement which could relax the tight pressure engagement at the sides of the connection, while the curled ends themselves are curled on such short radius compared to their thickness that they are essentially rigid and do not relax resiliently. With the pressure engagement thus maintained over the length of the forged connection a secure mechanical engagement is assured and corrosion does not work up between the contact surfaces.
  • FIG. 1 is an isometric phantom view of the die set at the beginning of its operation for applying a terminal connector to an ordinary insulated wire conductor With the end of the wire stripped to make contact with the central conductor;
  • Figure 2 is a similar view of the same die set at the end of its operation, showing a connection forged thereby on the end of a wire;
  • Figure 3 is an enlarged cross section of a connection made as illustrated in Figures 1 and 2;
  • Figure 4 is a fragmentary view in longitudinal vertical section of a modified die set and electrical connection crimped therein.
  • a #14 wire AWG has a diameter of 64 mils (.064").
  • the terminal connector used for this is made of sheet metal of twenty mils thickness (.020), and the ferrule forming portion thereof is formed to a U shape cross section with a rounded bottom and substantially straight sides flaring a little toward the top to facilitate gathering in of the wire.
  • the diameter of the U measured at a height of thirty-two mils above the bottom inside surface of the U (at a height equal to the radius of the Wire), is approximately equal to, but advantageously a little less than, the diameter of the wire, in the present example about sixty mils, and the inside of the U flares to a width a little greater than the wire, e. g., to about ninety mils i. d.
  • the dies 14 and 16 With the terminal connector 10 having its ferrule forming portion 12 positioned on the anvil 14 of the die set as shown, the dies 14 and 16 are brought together to a position shown in Figure 1.
  • the wire 17 may be inserted into the upper part of the U of the connector portion 12 or into the female die 16 above the connector. In any case, as the dies are closed together, the upper ends of the portion 12 are forced along the converging surfaces of the recess in the female die 16 and eventually meet over the ridge in the top of the female die recess, thus gathering in the wire it it was not already positioned within the ferrule portion 12.
  • the overall dimension of the ferrule forming portion at a height above the inside of the bottom equal to the radius of the wire is sixty mils plus forty mils (twice the thickness of the ferrule metal), and this tends to be expanded somewhat when the wire is driven down into the bottom because of the four mils greater diameter of the wire than the interior diameter of the ferrule portion.
  • the recess in the female die is formed with two approxinately semi-cylindrical surfaces 20, 21 in the top meeting 111 the central ridge. Actually, these are somewhat less than semi-cylindrical since the radius of their curvature is slightly more than one-quarter of the width of the die recess at the level of their axes of curvature. This radius may be, for example, between twenty-three and twentyfour mils instead of twenty-two and a half mils as would be necessary to give two complete and tangent semi-- cylinders.
  • the sides 22 and 23 of the die recess are tangent to the sides of the cylindrical surfaces 20, 21 respectively, and may be parallel for a short distance, as described above, or for ease in manufacturing may be slightly flared from the surfaces 20, 21, e. g., may be tangent to the cylindrical surfaces at 3 to the axis of symmetry of the die recess (6 included angle between the sides).
  • the sides 22, 23 are flared at said 3 angle for a substantial distance until the inside diameter between the sides is at least equal to the o. d. of the ferrule forming portion at radial height above the bottom.
  • the sides of the recess are more sharply flared, e. g, at an angle of 45", this portion of the die recess serving to automatically position the ferrule forming portion of the connector, and may also give the initial inward bending of the flared sides of the ferrule portion.
  • the bottom of the die at a height equal to the radius of the wire plus the thickness of the ferrule has a width of ninety mils, and this width is maintained substantially to the level reached by the anvil 14in the completion of the final forging operation.
  • the anvil 14 has a width to give a close fit in this portion of the female die 16.
  • the first elfect of this is to increase the height by changing the wire from circular to elliptical form and by squeezing apart of the metal from the bottom of the U into the sides, but in the final compression step the dies come together until the height is about seventy-five percent of the width and, as pointed out above, this requires substantial flow of the metal under the forging pressure of the dies.
  • the width of the die in the portion into which the ferrule is finally compressed shouldbe no greater than the diameter of the wire plus twice the thickness of the metal of the ferrule, but should be between eighty and one hundred percent of said diameter plus twice the thickness of the metal, and the height of the final forged connection should be about two-thirds to three-quartersor, at the outside, from sixty percent to eighty-five percent of the width of the forged connection. Obviously, the lower heights would have to be used with the greater widths in these ranges, and vice versa.
  • the 3 angle and 45 angle in the female die are not critical, but are respectively angles at which the open ferrule form ing portion is readily cammed into centered position on the anvil by the closing together of the dies, and in which the ferrule portion and the Wire can be laterally compressed by being cammed along the converging sides when driven to the bottom of the recess.
  • FIG 4 is shown a modified anvil and the connection crimped thereon.
  • transverse blunt ridges are provided which indent the ferrule wall into the wire at a position or positions spaced from the ends for the purpose and results indicated above.
  • My invention is applicable to either solid wire or stranded wire. Since solid wire does not have the voids between the strands to be filled, it does not require the same degree of lateral flow in the metal in the wire, and therefore can be satisfactorily crimped with less lateral compression with respect to the initial diameter of the wire than in the case of stranded wire, but it is important in either case that the metal be flowed so as to give a substantially solid cross-section which substantially fills the inside of the curled ends 18 and 19, and thus keys them against lateral movement which might open the seam. This keyed-in form, moreover, combined with the otherwise nearly square cross-section, gives a security toward torsional stress and alternating torsional stresses, which is most important with solid wire.
  • wires as small as #36 have been successfully connected in terminals crimped in accordance with the present invention, and wires as small as #48 have been crimped together with larger wires by the present invention, both under commercial conditions of operation, and. giving satisfactory performance requirements.
  • This advantage of the crimp appears particularly when wires of eighteen gauge and smaller, are used in the comparison with other available types of crimped connection.
  • the method of making electrical connection to a conductor which comprises forming a connector of malleable sheet metal with a ferrule-forming portion U-shaped in cross-section with the sides of the U flared to an inside diameter greater than that of the conductor and the diameter of the conductor being at least as great as the inside diameter at a point half the thickness of the conductor above the bottom of the U, inserting the conductor, and curling together the ends of the projecting sides of the U and driving them against the conductor, and forging at least a portion of the resulting ferrule and conductor to generally rectangular configuration of a width between and 100 percent of the diameter of the conductor plus twice the thickness of the metal of said ferrule-forming portion before said forging and to a height between 60 and percent of said width, said height being measured from the top of said curled ends to the mean depth below the maximum diameter, the forging including conforming the conductor by radial deformation and longitudinal extrusion to the inside surface of the ferrule.
  • the method of making electrical connection to a conductor which comprises forming a connector of malleable sheet metal with a ferrule-forming portion U-shaped in cross-section with the sidesof the U. flared. to an in.-
  • the method of making electrical connection to a conductor including the steps of forming a connector of malleable sheet metal with a ferrule-forming portion U- shaped in cross section; disposing the conductor in the ferrule-forming portion; curling together the ends of the projecting sides of the U and driving them against the conductor; and forging the resulting ferrule to generally rectangular configuration including applying pressure downwardly at the curled ends of the U and upwardly at the bottom of the U, simultaneously therewith applying downward and inward pressure to the sides of the U to decrease continuously the maximum lateral diameter of the ferrule during formation and to form therefrom planar ferrule sidewalls abruptly extending from the ferrule bottom at an angle of convergence of approximately 6 toward the curled ends, and conforming the conductor by radial deformation and longitudinal extrusion to the inside surface of the ferrule.
  • the method of making electrical connection to a conductor which comprises forming a connector of malleable sheet metal with a ferrule-forming portion U-shaped in cross section with the sides of the U flared to an inside diameter greater than that of the conductor and the diameter of the conductor being approximately as great as the inside diameter at a point half the thickness of the conductor above the bottom of the U, inserting the conductor, curling together the ends of the projecting sides of the U and driving them against the conductor, and forging at least a portion of the resulting ferrule and conductor to generally rectangular configuration to conform the conductor by radial deformation and longitudinal extrusion to the inside surface of the ferrule, the forging including applying pressure downwardly at the curled ends of the U and upwardly at the bottom of the U simultaneously with continuously decreasing the maximum lateral dimension of the ferrule being formed by applying downward and inward pressure to the sides of the U to form a ferrule having a width between and percent of the diameter of the conductor plus twice the thickness of the metal of the ferrule-
