Definitions

  • ABSTRACT Contact means for improving the contact between acjacent conductive members comprising a substantially flat, multiple toothed member having a selectively proportioned slotted aperture arranged to permit the com tact means to be disposed about a binding post or similar fastening element.
  • the toothed projections which may be disposed on at least a portion of either one or both surfaces of the contact means are selectively dimensioned to bit into and engage the adjacent conductive surface of one or more conductors urged thereagainst as the contact means is interposed between the conductor and the adjacent conductive member.
  • the contact means may be formed either as discrete, single apertured members, or as multi-apertured members wherein the apertures are selectively spaced preferably to bridge two or more adjacently disposed binding posts or the like.
  • the contact means may be provided in strip form and selectively scored or recessed to enable convenient separation of the interconnected members.
  • FIG. 1 A first figure.
  • the invention is directed to the field of contact means and principally to means for improving the electrical contact between adjacent conductive members.
  • the device may be conveniently employed to increase the versatility of existing electrical devices where such devices heretofore have been designed primarily for use with copper conductors and wherein it is desired to permit their employment with aluminum conductors.
  • the device may be formed with either a single slotted aperture or a plurality thereof suitably spaced to permit the use of the device as a bridge between existing studs or mounting members.
  • the disclosed device may also be formed as a series of interconnected members with a suitably weakened portion between adjacent members to permit the separation of one member from another, thus permitting the device to be conveniently manufactured, stored and used in strip form.
  • the device may be interposed either between the base plate of the support means and the respective conductor or conductors, or, in the alternative, between a plurality of conductors to advantageously increase the area of contact therebetween.
  • the teeth may either be formed from the base material of affixed thereto, and may extend from either one or both surfaces of the device.
  • the tooth height may be suitably dimensioned to permit sufficient engagement and penetration into the conductive portion of, for example, aluminum conductor wire, to permit electrical contact thereto, despite the existence of an oxide film or other insulating material over the outer surface thereof. It is therefore an object of this invention to provide an improved electrical contact surface.
  • FIG. 2 is a front elevational view of the device of FIG. 1 showing its use in a typical assembly.
  • FIG. 3 is a front elevational view of the device of FIG. 1 showing a further use thereof in a typical assembly.
  • FIG. 4 is a front elevational view, in section, of a further embodiment of an insulation and oxide piercing contact means constructed in accordance with the concepts of the invention, as employed in a typical assembly.
  • FIG. 6 is a perspective view of still a further embodiment of insulation and oxide piercing contact means constructed in accordance with the concepts of the invention.
  • FIG. I0 is a fragmentary perspective view, partly in section, of still a further embodiment of insulation and oxide piercing contact means constructed in accordance with the concepts of the invention.
  • FIG. 11 is a fragmentary perspective view, partly in section, of still another embodiment of insulation and oxide piercing contact means constructed in accordance with the concepts of the invention.
  • contact means 20 is shown as having a substantially rectangular configuration, other suitable contours such as a generally round, oval or elliptical configuration may be readily employcd without departing from the spirit of the invention and within the concepts herein disclosed.
  • electrically conducting sheet stock such as, for example, copper, brass, aluminum, or other suitable metals. Because of the inherent resiliency of such materials, contact means 20 may thus be conveniently urged over the body portion 34 of an existing fastener such as 36 (FIG. 2) where the width of the slot 28 is somewhat less than the diameter of the body portion 34 of fastener 36. The diameter of aperture 32 is proportioned to conveniently accept the body portion 34 of fastener 36 therethrough with a slot clearance thereabout.
  • Fastener 36 is thereafter tightened down into the support member 40 causing the conductor 42 to be urged against the upper protrusions 26 on contact means 20 causing said protrusions 26 to pierce the outer surface of conductor 42 and engage the inner conductive portion 46 thereof.
  • the conductor 42 is covered with an insulation coating, as is commonly employed with many copper conductors, or an oxide coating developed over the outer surface of a typical aluminum conductor, effective electrical contact may thus be made to the conductive portion thereof, the height of protrusions 26 being selectively chosen to afford adequate piercing in such event.
  • the lower protrusions 26 disposed on surface 24 of contact means 20 are caused to engage and bite into the adjacent surface 48 of support member 40.
  • FIG. 4 there is shown a typical use of contact means 66 constructed in accordance with the concepts of the invention and comprising a plurality of pointed protrusions or teeth 68 on a portion of a single surface thereof.
  • This arrangement may be conveniently employed to provide an electrical coupling or connection between a pair of conductors such as 70, 72 substantially in the manner illustrated.
  • contact means 66 is disposed over the body portion 76 of fastener 74 with the nontoothed surface of contact means 66 being disposed adjacent the head portion 78 of fastener 74.
  • the conductors 70, 72 are then interposed between the toothed surface 80 of contact means 66 and a support member 82 adapted to receive the fastener 74.
  • Conductors 106, 108 may be selectively stripped, substantially as shown, prior to the assembly, but this operation is not necessary since the protrusions 96 may be suitably proportioned to have a length sufficient to penetrate the full outer insulation covering of said conductors 106, 108 and any oxide coating which may be present and penetrate the inner conductive portion thereof.
  • Contact means 84 may be supplied as individual units as shown in FIG. 5 or in strip form, substantially as shown in FIGS. 10 and 11. In the strip configuration illustrated in FIG. 11 there is provided separating means in the form of a plurality of generally transversely extending recessed portions 110 each disposed intermediate a pair of contact means 84.
  • Recessed portion 110 is appropriately dimensioned to provide a generally frangible area adjacent thereto, thereby facilitating the removal of one of said contact means 84 from the remaining strip merely by bending or otherwise deforming the strip about such recessed portion 110.
  • FIG. 10 A similar arrangement is illustrated in FIG. 10 wherein there is shown a plurality of interconnected contact means 112 each constructed in a manner similar to that illustrated with respect to contact means 20 shown in FIG. 1. The juncture between each pair of contact means 112 is defined by a recessed portion 114 similar to the recessed portion 110 shown in FIG. 11, and in a similar manner provides a means for separating one of said contact means 112 from the adjacent strip.
  • Contact means 84 shown in FIG. 5 may be modified to provide an arrangement such as that shown in FIG.
  • Insulation and oxide piercing contact means comprising: a body member formed of flat electrically conducting metallic material and having a first surface and a second surface, said surfaces defining the thickness of said body member, at least one smoothly contoured outer edge, at least one selectively proportioned aperture extending between said first and said second surfaces, at least one smoothly contoured inner edge at least partially defining the periphery of said aperture, and at least one restrictively proportioned slot extending between and communicating with its associated aperture and at least a portion of said outer edge of said body member; and a plurality of discrete, generally sharply pointed protrusions having a predetermined length and extending outwardly generally normal to the plane of said body member, said protrusions being disposed generally uniformly over substantially the entire area defined by at least one of said first and said second surfaces, said protrusions being confined solely to the area intermediate but not including said inner edge and said outer edge of said body member and arranged in such close proximate relationship one to another as to penetrate the outer surface of and selectively
  • said body member has at least two apertures in selectively spaced arrangement extending between said first and said second surfaces thereof, and at least two slots, each extending between and communicating with its associated aperture and a portion of said outer edge of said body member.
