Definitions

  • ABSTRACT A pair of complementary surfaces are connected together electrically by compressing between them a connector formed of a resilient metal strip having a pair of longitudinally extending and longitudinally corrugatedly contracted side portions interconnected by a plurality of transversely extending parallel tongues or contact lamellae each having one end connected to one side portion, another end connected to the other side portion, and a middle waist region substantially wider than said ends.
  • the side portions may be sinusoidally corrugated or may be formed as a succession of flattened loops.
  • the present invention relates to an arrangement for forming an electrical connection between two surfaces. More particularly this invention concerns an electrical connector for interconnecting two bus bars or the like.
  • Another ojbect is the provision of such a connector which has greater current'carrying capacity and lower resistance to electrical current flow than the prior-art devices.
  • the tongues have middle regions which are substantially wider than their ends.
  • these tongues are formed in an initially flat metal sheet by punching out slots having a dumbbell profile, i.e. wider at the ends than at the center.
  • the number of tongues per unit length in such a connector is substantially increased so that the conductivity across it is also greatly increased.
  • the longitudinally contracted sides can be formed with sinusoidal corrugations. It is also possible to form them as a succession of flattened loops, this being effected by crimping or wrinkling the side portions, then flattening them without allowing them to extend.
  • Such a connector can be used between two flat or curved surfaces. It is possible to apply a ring or disk connector of this type to a plug connector or the like, or conform it to any other desired shape.
  • FIG. 1 is a perspective view of a pair of bus bars connected together according to the present invention
  • FIG. 2 is a top view of the lower bus bar of FIG. 1;
  • FIGS. 3 and 4 are perspective views of two embodiments of the connector according to the present invention.
  • FIG. 5 is a top view of a connector according to this invention prior to contraction of its side portions.
  • connection 1 is formed between a pair of flat bus bars 2 and 3 by interposing therebetween a pair of generallly flat connectors 4.
  • a bolt 8 between the two connector strips 4 serves to secure these two bars 2 and 3 together and compress the strips 4.
  • the strips are held by longitudinal slots at their edges with a spacing less than the width of the strip.
  • each strip 4 comprises a pair of longitudinally corrugated side portions 7 formed with transverse corrugations 9 and joined together by tongues 5 which are wider at their middle regions 5' than toward their ends 5".
  • Slots 6 of dumbbell shape as shown in FIG. 5 in an noncontracted strip are formed in the original metal strip to give these tongues 5 the widened waist 5'.
  • the tongues 5 are also twisted about their longitudinal axes, that is, transverse to the longitudinal direction of the strip 4 as shown by arrow A, which is the direction of contraction of the side portions 7.
  • FIG. 4 shows a strip 4' which has side portions 7' formed as a succession of overlapping loops 10, which are formed by crimping or wrinkling the portions 7' as in FIG. 3, then flattening the corrugations in one direction while preventing the strip 4 from extending.
  • the extent of overlap of the loops 10 determines the extent of contraction, in FIG. 3 the determining factor is the height of the crests of the corrugations 9. In both cases it is easy to produce connector strips of almost any desired conductivity.
  • An electrical connector for electrically interconnecting two surfaces, said connector comprising a planar conductive metal sheet having a pair of generally coplanar longitudinally extending and longitudinally corrugatedly contracted side portions, the extended lengths of said side portions exceeding the length of said sheet along said side portions, and a plurality of parallel transverse resilient tongues extending between said portions and twisted from the plane of said portions, said tongues having ends joined to said sides and middle regions wider than said ends, said side portions being uniformly corrugated over their entire lengths and having more than one corrugation per tongue.
