Definitions

  • soldered electrical connections which have been so widely used, have several disadvantages. are the difiiculties in making a great number of electrical connections which are inexpensive and yet uniform, and doing so rapidly yet while maintaining excellent mechanical strength and electrical characteristics.
  • attention has been directed towards the so-called pressure welded or crimped connectors wherein an enveloping metal barrel or ferrule is squeezed tightly onto a bare wire conductor so that the wire and the barrel are firmly adherent after the crimping tool'is removed.
  • pressure welded or crimped connectors wherein an enveloping metal barrel or ferrule is squeezed tightly onto a bare wire conductor so that the wire and the barrel are firmly adherent after the crimping tool'is removed.
  • connection in some crimped connections a single indentation is made to combine the barrel and the conductor.
  • This form of connection generallyv has poor mechanical strength and it is difficult even for a skilled operator to make successive crimps 'which are uniform.
  • the double indent or W type crimp as described in the above-mentioned patent has proven superior in service, but the use of the present invention provides certain advantages thereover, as explained here and after.
  • the double indentors for a crimping tool are made to exacting specifications and are machined to close tolerances and exact curvatures, whereas the female dies or nests are considerably easier and less expensive to make.
  • the final crimp. should meet, and preferably exceed, the minimum pull-out or tensile strength values adopted by the various ofiicial standardization groups. Additionally, the torsion strength of the connection should be high lest the conductors become loose by twisting and bending actions. The corrosion resistance of the connection should also be high to avoid changes in the electrical characteristics of the connection; for example, a small change in the resistance of a high current carrying conductor system is reflected in excessive power losses and even overheating of the connection.
  • connection In general, the existence of voids or air spaces in the crimped connection tends to impair the corrosion resistance of the connection and voids should be kept to a minimum.
  • the external form of the connection should be symmetrical not only to avoid localized stresses but also so that standard size insulating sleeves, if desired, may be put on the connection without ditliculty. Sharp flares or edges also are not desirable insofar as they tend to cut insulating sleeves and are also objectionable electrically in that they may cause voltage breakdown due to corona discharge.
  • a further factor is that the barrel of the connection should not be sheared through or pierced. Since most barrels are tinned copper, ordinarily a visual test reveals that shearing has occurred if the contrasting color of the conductors is visible to the unaided eye.
  • Fig. l is a perspective view of an electrical connection crimped by dies made in accordance with one embodiment of the invention.
  • Fig. 2 is an enlarged sectional view taken transversely through the connection of Fig. 1 and along the line 22 thereof;
  • Figs. 3, 4 and 5 are sectional elevations taken through a pair of crimping dies made according to this invention and these figures show a ferrule and conductor within the dies in progressive stages of crimping;
  • Fig. 6 is an enlarged view showing the outlines of the dies of Figures 35.
  • an electrical connector is generally indicated at 20 showing a ring contact portion 22 and the ferrule portion 24.
  • the ferrule portion 24 is crimped over the bare conductor ends 26 of insulated wire 28.
  • Substantially parallel indents or grooves 30 are shown in ferrule 24 as extending therein for the greater portion of the ferrule length and terminating a short distance (e. g. 5 from the respective ends of the ferrule. Ends 30a of the indents 30 are shown as sloping gradually upwardly from the greatest depth of the indent to the terminus of the indent.
  • Fig. 2 shows the characteristic W configuration of the cross-section of the crimp in Fig. 1 wherein the top of the central hump 34 is below the level of the top of the side horns 36.
  • the conductors 26 are shown as coined and extruded within the deformed ferrule 24.
  • Thin sidewalled sections 35 of ferrule 24 extend downwardly from the centrally, depressed hump 34 having seam 34a.
  • Folded and cold-worked beads or horns 36 extend along the outer edges of the crimp while the bottom 37 of the crimp conforms to the shape of the nest (see Fig. 3).
  • Fig. 3 is shown the indenters 42of the male die 39 as they approach the ferrule 24 as it lies in nest 44 of the female die 40.
  • the ferrule size shown is that of the smallest ferrule which may be satisfactorily usedwithin the range of the male die.
  • Figs. 4 and 5 depict partial and then completed crimping and emphasize the distortion achieved in cold working and flowing the ferrule 24 and conductors 26 to a cohesive mass.
  • Fig. 6 shows the construction of a'sp'ecific size nest 44 and indenters 42 in terms of dimensions which are:
  • E the maximum width of the nest
  • D the depth below the upper surface of the nest of the center of the radius of curvature of the greater portion of the nest- Szthe radius of curvature of the curved surfaces on the male die such as the ends ofthe indenters
  • L the overall height of the indentors
  • A the distance from the bottomof each indentor to the bottom of the nest when the crimping dies are fully closed. This dimension largely determines the final cross-sectional area of the crimped connection.
  • An additional feature of this invention is that the configuration of the outer, surface of'each indentor is so curved (or has a small straight portion) thatit is substantially parallel to the straight portion ofthe adjacent parts of the nest cavity (see Fig. 6). This relationship of substantial parallelism is maintained for the smallest size barrel for which a given indenting die is adapted.
  • the substantially parallel relationship described above will be maintained, preferably by flattening the mouth of. the nests so that the slope thereof is about 18 from the vertical. But in the wider diameter ferrule as the radius of curvature of the nest increases, the straight portion of the nest is brought upwards more abruptly to compensate for the greater width of the nest, e. g. the slope from the verticalmay be about 16 or.l4 or even less.
  • the thickness of the horn section of the crimped connection is maintained over a varietyv of sizes at about 100% of the original uncrimped wall thickness of the ferrule.
  • theconductor metal may vary in nature as well as the shape of the conductor; soft copper, hardened conductors, aluminum, etc., whether solid, round, square, oval or stranded may be used.
  • solid rather than stranded conductors it is sometimes found advisable to deform the conductor before crimping the connection. This may be done,,for example, by grasping it to a generally oval shape in cooperating cavities as are shown in Fig. 6'. With oval conductors, these should be positioned in the barrel within the nest so that the smaller or minor axis of the conductoris perpendicular to the bottom of the nest.
