Definitions

  • This invention relates to the field ofelectrical connections and electrical connectors and the .methods and means for making same. More particularly, the invention pertains to solderless, pressure forged (or 'crimped) connections wherein the connector firmly encloses the conductor to such an extent and in such a manner that a superior electrical connection results.
  • a solid conductor is difiicult to crimp and compress compared to a stranded conductor into which connector prongs may be driven and which can be readily formed into many more configurations than can a solid conductor. Due to the rigidity and relative inelasticity of a-solid conductor,
  • the invention here presented opens up new uses and possibilities for solid wire particularly with nontubular conductorreceiving barrels.
  • This invention takes advantage of the peculiar properties of solid'wire to make a firm connection by forcing solid wire up through "an opening in the connector barrel during the crimping operation.
  • This Wire metal provides a rigid-projection the sides of which-are pressed against the edges of the opening in the connector barrel and due to the characteristics of a solid wire, this pressure is relatively unyielding, fastly fixing the connector to the wire.
  • Figure 1 shows a perspective fragmentary view of the conductor and connector
  • Figure 2 shows a fragmentary plan view of a die for crimping a connection embodying this invention
  • Figure 3 is a cross section of Figure 2 taken on line 3-3;
  • Figure 4 is a fragmentary view in perspective showing a connection of this invention being crimped in an anvil and die of this invention
  • Figure 5 is a cutaway plan view of a connection being crimped in an anvil and die of this invention.
  • Figure 6 is a cross sectional View taken at 6-6 of Figure 1;
  • Figure 7 is a cross sectional view taken at 7-7 of Figure 1;
  • Figure 8 is a fragmentary perspective view of a strip of terminals such asmay be used in making a connection as shown in Figure 1.
  • I11 Figure 1 is shown a completed connection embodying principles of this invention.
  • Barrel 21 may take many forms but here is made from a flat piece of metal stock which has ears 22, 23 Ued up and formed about the conductor in the manner set forth in Hammell application, Serial No. 410,250, filed February 25, 1954.
  • the dies used in the illustrative form herein are similar to the dies in the Hammell application with the exception that dies incorporating the present invention have a hollow or groove, such as flute 25 in Figures 2 and 3 and slot 26 in Figure 4.
  • wire and connector metal will flow into these depressions in the dies and wire metal will provide a lock by exerting pressure against the connector metal edges, such as connector edges 31, 32 shown in Figure 5.
  • wire metal is squeezed from the pressure areas to the ends of the connector and towards'the center of the connector where the reliefs have started to form.
  • the metal is pushed from each pressure area towards the center at the same time so that metal is forced into the relief area from all directions simultaneously making the contact between the metal and connection edges 31, 32, shown in figure, extremely tight. This is more effective than crimp ing one area and then another.
  • the wire metal in the compressed areas on either side of the reliefs is work hardened during the crimping operation and therefore does not substantially spring back away from firm contact with the connector.
  • these Work hardened areas are utilized to hold the extruded wire metal in its position, tight against the connector edges.
  • the work hardened metal forms a hard ring around the extruded portion, which is still resilient and in compression, keeping it in position so that it will not work free.
  • this invention isdesigned to utilize a previously undesirable property. 7
  • the metal used in the connector is full hard, fine grain, 7030 cartridge brass.
  • the wire is light annealed ASTM designation B3-5ZT. These metal properties may of course be varied.
  • Figures 2, 3 and 4 Two'of the many possible dies used to form the connection of this invention are shown in Figures 2, 3 and 4.
  • Figure 2 is shown a fragmentary plan view of a known type ,of die but'with the center portion fluted.
  • This die is relatively inexpensive to make and very sturdyl
  • this particular die has a clearance between the tangent of the top of die arcs and the top of the flute of about .030 inch while the distance across both die arcs is about .130 inch;
  • the depth of the flute is about .050 inch and the depth of the die (also the length of the crimp) is .187 inch.
  • the flute in this embodiment is centered in the die depth.
  • the are that defines the top of the flute has a radius of about 7 inch.
  • the die shown in Figure 4 has the same dimensions as that shown in Figures 2 and 3 with the exception that the flute is extended to become a slot the entire width of the die.
  • the end of the connector nearer the wire insulation is bell mouthed to relieve strain on the wire by gradually going from an area of great pressure to one of slight pressure on the wire.
  • the extruded portion of the wire in the center of the crimp is covered with connector reliefs 37, 38 which serve to protect the wire metal but even without such coverings, the connection would stand up well under corrosive conditions because the crimp on either side of the extruded wire metal is tight enough to prevent water or other matter from entering.
  • relief 37 is shown to overlap relief 33. Since the reliefs start to form about the time or slightly before the ends of the Ued up sides reach the top of the die arcs, the edges of the relief have been separated from said sides by the time they meet near the completion of the crimpin stroke. At this point one relief edge will slide over the other with a resultant cross section as shown in Figure 6.
  • An electrical connection comprising a connector having an elongated base and sidewalls extending from said base, a conductor disposed along said base, said sidewalls being tightly folded about said conductor with the ends thereof meeting in a longitudinal furrow in the connection, anintermediate relief in the connector extending transversely across said folded sidewalls, metal of the conductor extending into said relief and in forceful engagement with the transverse edges of the connector at the relief for firmly securing the conductor within the connector.
  • connection as defined in claim 1 wherein the portions of the connector sidewalls defining said relief are at least in part raised above the unrelieved sidewalls sufiiciently to form an opening through the connection, said unrelieved sidewalls presenting at said opening transverse faces substantially perpendicular to the longitudinal axis of said conductor.
  • the method of forming a U-shaped connector about an electrical conductor to produce a pressure connection including the steps of: disposing the conductor along the trough of the connector, folding the end portions of the sidewalls of the U inwardly to form a ferrule generally encompassing the conductor, displacing two longitudinally spaced sections of the sidewalls inwardly of the ferrule from an intermediate relief section therebetween to form at the section'boundaries transverse faces extending across the end portions of the sidewalls and substantially perpendicularly to the longitudinal axis of the conductor, and compressing the spaced sections tightly about the conductor relatively to raise an intermediate section of con with the transverse faces of the spaced sections.
