Definitions

  • the invention is directed to the field of electrical connectors and principally to an electrical connector adaptable for use with both insulated and noninsulated electrical conductors such as copper, aluminum and other commonly employed electrical conductive materials having a variety of cross-sectional configurations.
  • Electrical connectors generally comprised a conductor engaging means adjacent a suitably configured coupling means to provide an electrical connection between the connector and an adjacent conductor terminated therewith.
  • the conductor was sheathed with insulating material, as for example a plastic coating or the like, it was generally necessary to remove a portion of the insulation therefrom to provide an uninsulated portion for engagement with the conductor engaging means of the connector, which was selectively proportioned to receive the uninsulated portion of the conductor while restricting the entrance therein of the insulated portion adjacent thereto.
  • the conductor engaging means was insufficiently restrictive to prevent the inadvertent receipt therein of at least a portion of the insulated segment of the conductor, resulting in a defective electrical connection between the connector and the adjacent conductor, which was generally extremely difficult to detect after assembly.
  • the invention is directed to an improved electrical connector which overcomes the limitations noted above with respect to prior art devices by providing a calculably determinable plurality of selectively proportioned piercing members effectively disposed on a base member and arranged to enter and penetrate an adjacent conductor, resulting in an electrical connection therebetween which is more effective, efficient, secure and reliable than that furnished by such prior art devices.
  • Each of the piercing members may be formed by either one of several suitable methods, such as by lancing, skiving or punching a portion of the base member on which said piercing members are disposed.
  • Each of said piercing members generally comprise a first portion adjacent the base member and proportioned to either engage the insulated portion of an adjacent conductor or bridge the spacing between the base member and the adjacent conductor surface in an uninsulated conductor, and a second portion substantially colinear with the first portion, extending therefrom, and selectively dimensioned to enter, penetrate and thereafter provide a predetermined conductor contact area defined generally by the surfaces thereof.
  • the aggregate conductor contact area defined by the surfaces of the second portion is proportioned, in one embodiment, to at least equal the cross-sectional area of the conductor engageable therewith, thus assuring the required electrical contact therebetween, the depth of penetration of the piercing members being restrictively proportioned, within a predetermined range, to prevent mechanical injury to the conductor.
  • the piercing members are dimensionally proportioned to define an aggregate conductor contact area at least equal to the area of the immediately adjacent base member, from which they depend, thus providing a total area of contact with the conductive portion of an insulated conductor essentially equivalent to the surface area of the encompassed conductive portion, the number of piercing members and the depth of penetration being readily calculable and definable.
  • Various configurations of the connector may be provided to permit its adaptability for use in conjunction with round, flat or square conductors of either copper, aluminum or other commonly employed conductive materials, each embodiment having specifically definable, and predeterminedly proportionable and arrangeable piercing members to insure optimum electrical and mechanical engagement with an associated conductor. It is therefore an object of this invention to provide an improved electrical connector.

  • the remaining portion 42 of the conductor engaging portion 32 is diametrically enlarged to accept a portion of the unstripped insulated conductor 36, substantially as shown, thus providing a partial strain relief where desired.

  • an electrical connector 58 having a plurality of piercing members 60 selectively disposed on a base member 62 and depending inwardly in a manner similar to that shown in FIG. 2, but differing, however, in the particular arrangement thereof.
  • Piercing members 60 of electrical connector 58 are selectively arranged to define essentially two longitudinally separated groupings, generally as shown, to permit engagement with predetermined portions of an adjacent conductor receivable within the conductor coupling portion 64 of connector 58.
  • Extending from base member 62 is a spade-type coupling means 66, forming no part of the invention, but merely providing a convenient means for coupling connector 58 to a further member (not shown) where desirable.
  • FIG. 4 A further modification of an electrical connector 68 constructed in accordance with the concepts of the invention is shown in FIG. 4.
  • Connector 68 comprises a plurality of piercing members 70 selectively disposed on a base member 72 and arranged to encompass, enter and penetrate the conductive portions of two or more conductors (not shown), each of which may be insulated or noninsulated, thereby providing an effective, rigidly secure splice-type connection between the conductors.
  • an electrical connector such as 74, as shown in FIG. 5, may be advantageously employed.
  • Connector 74 comprises a serpentine-like base member 76 selectively formed to define a pair of spaced, conductor receiving apertures 78, 78' generally as shown.
  • each ofthe apertures 78, 78' Extending inwardly into each ofthe apertures 78, 78' are piercing members 80 in generally opposing relationship and selectively arranged to enter and penetrate an adjacent, substantially flat conductor (not shown) disposed within each of said apertures 78, 78, thus permitting the engagement of connector 74 to each conductor separately, base member 76 providing the electrical connecting path therebetween.
  • an electrical connector 82 similar to connector 74 of FIG.
  • Connector 48 of FIG. 2 may be modified to provide a connector such as 88, as shown in FIG. 6, to provide an electrical connection between a substantially square conductor such as 90, and said connector 88. A portion of the base member 92 of connector 88 has been cut away in FIG.
  • a connection between the connector and an adjacent conductor is generally accomplished by urging the base member of the connector tightly against the adjacent surface of the conductor with sufficient force to advance the piercing members of the connector into intimate engagement with the conductive portion of the associated conductor, each piercing member being selectively proportioned to penetrate the conductor a predetermined depth, as is more fully described below.
  • FIG. 8 there is shown a plurality of selectively proportioned piercing members 96 disposed in prearranged order adjacent a portion of a base member 98 according to the concept of the invention.
  • the piercing members are arranged in a generally regular diamond pattern, providing a predeterminable series of alternating piercing and nonpiercing areas adapted to afford the required electrical and mechanical engagement with an adjacent conductor (not shown).
  • the arrangement of piercing members 96 shown in FIG. 8 may be modified to define a pattern similar to that shown in FIG. 9, wherein said piercing members 96 are disposed on a portion of a base member MN) in generally spaced, parallel rows in oblique angular relationship with the longitudinal axis thereof.
  • FIG. 10 there is shown a selectively proportioned piercing member 102 of an electrical connector constructed in accordance with the concepts of the invention.
  • Piercing member 102 is formed by lancing a portion of the base member 104 as at 106 and deflecting the lanced portion outwardly generally normal to the plane thereof.
  • a plurality of upstanding piercing members such as 108 may be formed in nest-like fashion about a generally centrally lanced portion 110 of base member 112.
  • each piercing member may be formed as by skiving or the like, as is clearly shown in FIG.
  • a portion of the base member 118 may be partially deformed to define an upstanding, generally conical piercing member such as 120.
  • the specific shape of the piercing member is relatively unimportant, and may assume any one of the configurations shown, or any other desired shape, each is selectively proportioned, according to the concepts of the invention, to provide a predetermined depth of penetration and a calculably determinable aggregate conductor contact area relative to the particular dimensions and configurations of an adjacent conductor engageable therewith.
  • electrical connector 121 comprises a predetermined number of piercing members 122 depending from a base portion 124 generally normal to the plane thereof, said piercing members 122 being shown embedded within the adjacent conductive portion 126 of an insulated conductor 128.
  • Each selectively proportioned piercing member comprises a first portion 130 adjacent the base member 124, and engageable with an immediately adjacent insulating portion 132 of conductor 128, and a second portion 134 adjacent the first portion 130 and extending therefrom, said second portion 134 being arranged to enter and penetrate the conductive portion 126 of conductor 128 within the range of 5 to 50 percent of the minimum cross-sectional dimension thereof.
  • the surfaces defining each of the second portions 134 comprise a conductor contact area dimensionally proportioned with respect to the predetermined number of piercing members 122, to provide an aggregate conductor contact area at least equal to, in one embodiment, the crosssectional area of the conductive portion 126 of conductor 128.
  • the number of piercing members required to provide a superior electrical connection between connector 121 and conductor 1128 may be readily determined, in one embodiment, by dividing the total cross-sectional area of the conductive portion 126 of conductor 128 by the conductor contact area per piercing member.
  • the depth of penetration within the above specified range required to effect a proper electrical connection to the adjacent conductor may be conveniently determined from the above mentioned relationships of conductor contact area to conductor cross-sectional area.
  • certain mechanical considerations may dictate the minimum length of the conductor over which the connector may be satisfactorily engaged, to avoid undue stress or likelihood of fracture in the conductor, while maintaining adequate electrical contact therewith.
  • the length of engagement of connector 12 with the adjacent segment of conductor 128 is dimensionally indicated by the reference letter A. Having predetermined the value of dimension A, on the basis of mechanical considerations, it becomes a simple matter, according to the concepts of the invention, to calculably determine the number of piercing members 122, each having a specified conductor contact area required to effect the desired electrical engagement between connector 121 and conductor 128. Where cost is a major factor, the length of engagement as heretofore described may be proportionately decreased, as, for example, to conserve connector material, while maintaining superior mechanical and electrical engagement, as may be more clearly seen with reference to FIG. 15. In FIG.
  • the base portion 136 of connector 138 is shown as extending longitudinally adjacent an insulated conductor 140 a length indicated by the reference letter B.
  • length B is relatively short with respect to the cross-sectional dimension of conductor 1140
  • each of the piercing members 142 depending from the base portion 136 of connector 138 may be calculably proportioned to provide superior electrical engagement with conductor 140, it being necessary merely to insure that the aggregate conductor contact area defined by the product of the conductor area per piercing member 142 and the number of piercing members is at least equal to the cross-sectional dimension of the adjacent conductor 140. It will generally be found that where a relatively short engaging length B is employed, as exemplified in FIG.
  • each of the piercing members 142 may be proportionately greater than that required where the engaging length is somewhat longer, as is shown, for example, in FIG. 14.
  • the number of piercing members may be proportionately increased to account for the diminished con ductor contact area per piercing member resulting generally from the decreased length thereof.
  • piercing members 144i of an electrical connector 146 constructed in accordance with the concepts of the in vention, are shown engaged within the conductive portion M8 of a stranded insulated conductor 150.
  • engagement is attended by an inconsequential severing of a portion of the strands of conductor 15) immediately adjacent each of the piercing members 14 since any severed strands are effectively displaced by the electrically conductive material of the adjacent piercing member second portions, indicated generally at 152.
  • the connector is equally effective in providing an electrical connection to an uninsulated conductor, in a similar manner, it being necessary merely to calculably determine the proportions of the piercing members of the connector to provide the required penetration and aggregate conductor contact area according to the principles disclosed herein. It should also be understood that the connector is readily adaptable for use in conjunction with aluminum conductors or any of the commonly employed alloys thereof, the piercing members being equally as effective in penetrating the naturally occurring oxide coating generally disposed on the surface thereof, and engaging the conductive portion therewithin.
  • the aggregate conductor contact area defined by the piercing member second portions may be proportioned to at least equal the surface area of the adjacent base member portion encompassing said piercing members.
  • the surface area of the base member 100 immediately adjacent piercing members 6 may be defined by the product of the length L and the width W thereof.
  • the conductor piercing second portion of each piercing member 96 may be appropriately proportioned in relation to a predetermined number of such members 96 so as to provide the required aggregate conductor contact area, the conductor contact area of each piercing member 96 being determined generally by the surface defining the piercing member second portion.
  • the aggregate conductor contact area provided is at least equal to the conductor engaging area of an equivalently sized nonpiercing connector engageable with the outer surface of a particular conductor, thereby eliminating the necessity for providing a clean, conductive surface adjacent the connector, as is necessary with a non-piercing connector, while providing an at least equivalent electrical and mechanical engagement.
