Definitions

  • ABSTRACT An electrical connector having an internal tooth structure and a selectively grooved conductor engaging inner surface therebetween providing reducedthickness web portions responsive to the expansion and contraction of an enclosed conductor to prevent relative movement at the interface between the conductor and the connector thereby maintaining secure mechanical and electrical contact therebetween under even extreme conditions of temperature cycling.
  • the invention overcomes the limitations and difficulties noted above with respect to prior art devices by providing an electrical connector suitable for use with a conductor having either a similar or substantially different coefficient of expansion, thus providing a means for establishing a more secure, reliable, and economical electrical connection between, for example, a copper or copper alloy connector and an aluminum conductor than was possible with such prior art devices.
  • the device comprises a series of generally parallel protruding elongate teeth extending generally transversely across the inner surface of a crimpably deformable base member.
  • each selective pair of teeth is a selectively proportioned grooved portion defining a region of predetermined thickness somewhat less than the major thickness of the base member, thereby providing expandable web-like portions spaced one from another by ungrooved regions having a thickness essentially equal to the base member major thickness, the grooved portions being readily responsive to the expansion and contraction of a conductor about which the base member is crimped.
  • the established interface contact is thereby securely maintained upon the thermal cycling of the connection, thus insuring a superior electrical and mechanical connection therebetween.
  • the elongate teeth extending on either side of the grooved portions terminate in a relatively sharp edge adapted to pierce the outer surface of the conductor or the insulation disposed thereabout and penetrate the interior of the conductor, each pair of said teeth being disposed in such manner as to convergingly deform somewhat upon penetration of the conductor to engage the conductor interior in hook-like fashion to increase the engagement therebetween.
  • the grooved portions of the connector also serve to provide a pocket adapted to accommodate a portion of the conductor extruded thereinto during the crimping operation and subsequent expansion of the conductor.
  • the teeth may be provided with either arcuate or generally planar sides or a combination thereof to control the direction of deflection and to insure adequate conductor penetration and separation of the insulation disposed about an insulated conductor. It is therefore an object of this invention to provide an improved electrical connector.
  • FIG. 1 is a perspective view of an electrical connector constructed in accordance with the concepts of the invention.
  • FIG. 2 is a fragmentary elevational view, in section, of the device of FIG. 1 taken along the lines 22.
  • FIG. 3 is a perspective view of the device of FIG. 1 pre-formed into a generally U-shaped ferrule and having an attaching means coupled thereto.
  • FIG. 4 is a front elevational view, partly in section, of the device of FIG. 1 crimped about an insulated conductor.
  • FIG. 5 is a fragmentary side elevational view, in section, of a portion of the device of FIG. 1 in a first stage of engagement with an insulated conductor.
  • FIG. 6 is a fragmentary side elevational view, partly in section, of the device of FIG. I in a further stage of engagement with an insulated conductor.
  • FIG. 7 is a fragmentary side elevational view, in section, of the assembly of FIG. 6 after engagement showing the manner of expansion thereof upon thermal cycling of' the connection.
  • FIG. 8 is a fragmentary side elevational view, in section, of a portion of a further embodiment of a connector constructed in accordance with the concepts of the invention.
  • FIGS. 9 and 10 are fragmentary side elevational views, in section, of a portion of further embodiments of an electrical connector constructed in accordance with the concepts of the invention.
  • Connector 20 comprises a base member 22 having an inner surface 24 within which are formed a series of selectively spaced grooved portions 26 which, as shown in FIG. I, extend essentially transversely across substantially the entire inner surface 24 of base member 22.
  • Each of the grooved portions 26 extend preferably the same depth below the inner surface 24 of base member 22, the particular depth of the grooved portions 26 being controlled'or regulated to provide a predetermined thickness thereat designated as T in FIG. 2, which, as will be described in more detail hereafter, functions as an expandable web-like region.
  • the ungrooved portions of the base member 22 intermediate the grooved portions 26, and having a thickness designated in FIG. 2 as T provide relatively rigid regions therebetween.
  • the expandable web-like regions defined by the grooved portions 26 are shown in 'FIG. 2 as encompassing a length 28 bounded by the ungrooved portions of the base member 22.
  • Protruding outwardly from the inner surface 24 of. base member 22 are a series of preferably parallel transversely extending teeth 30 arranged in pairs extending substantially along the entire length of the grooved portions 26 and bordering the opposing sides thereof.
  • Each tooth 30, as illustrated in FIGS. 1 and 2 comprise generally arcuate exterior surfaces 32 convergingly disposed to define a relatively sharp edge 34 which, as will be explained in more detail hereafter, provides both insulation and oxide piercing means.
  • each tooth 30 is arranged generally coplanar with the adjacent sidewall of an associated grooved portion 26, the opposing surface of each tooth 30 terminating at the inner-surface 24 of base member 22.
  • each of the teeth 30 tend to buckle or deflect towards one another above an associated grooved portion 26 as they are forcibly urged into engagement with a conductor, the result of this tooth deflection being described in more detail hereafter.
  • Other tooth contours which may be similarly employed are shown, by way of example, in FIGS. 8 and 9. As illustrated in FIG. 8 one surface of each tooth is generally planar as at 36, and the other surface is arcuate as at 38. The embodiment illustrated in FIG.
  • toothform 9 includes a toothform having generally converging planar surfaces 40 and 42, surface 40 communicating with the sidewall of an associated grooved portion 26 to form an extending plane thereat similar to the arrangement shown in FIG. 8, while the opposing surface 42 is disposed at a generally oblique angle with respect to a plane normal to the plane of the inner surface 24 of base member 22 to form a saw-tooth type configuration.
  • the teeth may extend uninterruptedly across substantially the entire inner surface 24 of base member 22 a series of longitudinally extending slots or channels 43 as shown in FIG. 1 may be provided to permit the base member 22 to be more readily pre-formed or folded therealong to provide, for exam ple, a generally U-shaped base member 45, as shown in FIG. 3.
  • the height of teeth 30 above the inner surface 24 of base member 22 indicated in FIG. 2 as T is selected to provide predetermined penetration into the conductive portion of either an insulated or noninsulated conductor.
  • the tooth height T may accordingly, be less than that designed for use with an insulated conductor where, in the latter case, the teeth 30 are required to pierce through the outer insulative covering and then through to a similar depth within the conductive portion of the conductor.
  • the grooved portions 26 also function to provide expansion pockets for accepting a portion of the conductor as the base member 22 is crimped thereto and during expansion of the conductor.
  • FIGS. 4, 5 and 6, there is shown, in detail, the various stages in the assembly of connector 20 to a conductor such as 44.
  • FIG. 4 for example, there is shown, in cross-section, the base member 22 crimped about the insulated conductor 44, the teeth 30 of the base member 22 having been suitably proportioned to pierce through the insulated covering 46 of the conductor 44 and penetrate the conductive portion thereof to a predetermined depth, which may be in the order of from 5 to percent of the diameter of the conductor.
  • a predetermined depth which may be in the order of from 5 to percent of the diameter of the conductor.
  • the teeth 30 are caused to pierce through the insulative covering 46 and penetrate the conductive portion of the conductor 44 substantially as shown, the teeth 30 being substantially undeflected during this stage of the procedure.
  • the teeth 30, as illustrated in FIG. 6, arecaused to deflect under the increased crimping pressure and fold inwardly towards one another over the grooved portion 26 therebetween.
  • a portion 48 of the conductor 44 intermediate each pair of inwardly extending teeth 30 is thereby substantially extruded into the channel formed by the grooved portions 26 and lockingly entrapped therein.
  • the conductive portion ofthe conductor 44 is thus engaged by a substantial portion of that surface of the tooth 30 opposite the side adjacent to the grooved portion 26 and also by the other surface of the tooth 30 communicating with the grooved portion 26, together with the sides of the grooved portion 26 adjacent thereto. It is thus seen that a substantially greater area of contact is pro-' vided between the teeth 30 and the conductive portion of the conductor 44 than that provided solely by the tooth surfaces themselves.
  • the conductor 44 and the connector 20 are formed from materials having a similar coefficient of expansion, the connection illustrated in FIG. 6 will provide a superior electrical and mechanical connection between such members under even relatively severe thermal excursions because of their generally similar rates of expansion and contraction in response to temperature variations.
  • the connector 20 may be employed with equal efficacy where its coefficient of expansion is substantially different than that of the conductor to which it is to be attached.
  • the conductor 44 may be formed from aluminum or similar material, and the connector 20 formed from copper or copper alloy material, the difference in the coefficient of expansion between the two materials being in the order of approximately 1.5 to l, aluminum having approximately a 50 percent greater coefficient of expansion than copper.
  • the aluminum conductor will tend to expand or contract both radially and longitudinally within the connector to a greater extent than the copper connector. Referring to FIG. 7, the conductor 44 will tend to expand longitudinally as indicated by arrows 50, and 50 and radially outwardly generally as indicated by arrows 52, and 52'.
  • the radial expansion of the conductor 44 is accommodated, to a large measure, by reason of the chambers formed by the grooved portions 26 wherein the extruded portions 48 of conductor 44 are permitted to expand freely therewithin, thereby substantially reducing those forces tending to radially enlarge the connector and disturb the configuration of the original connection.
  • the elements thereof Upon the cooling of the assembly, the elements thereof will contract in a similar manner to their original state, thereby providing an unimpaired connection therebetween.
  • the interity of the joint may thus be preserved despite repeated cyclings of the assembly, thereby providing a secure, reliable, and permanent electrical and mechanical connection between dissimilar metals.
  • the outer surface of the base member 22 may be recessed as at 54 in FIG.
  • the recesses 54 extending in generally opposed parallel relationship to the grooved portions 26 formed in the inner surface of the base member to provide the desired thickness thereat.
  • This arrangement may also be found useful where it is desired, for example, to provide an insulative coating such as 56 about the outer surface of the base member 22, the recesses 54 thereby providing means for retaining the insulative covering 56 in position thereabout.
  • the embodiment illustrated in FIG. may also be found particularly useful where it is desired to reduce the depth of the grooved portion 26 below the inner surface 24 of the base member 22 while prothe base member 22 intermediate each pair of grooved portions 26 may be readily chosen to provide a greater or lesser degree of expansion, as necessary or desirable.
  • the length of the expandable web portion region 28 may be at least equal to or greater than the length of the ungrooved portion region indicated generally in FIG. 2 at 58. Conversely, where less expansion is desired, the length of the expandable web portion region 28 may be proportioned to be somewhat less than the length of the ungrooved portion region 58.
  • the connector 20 may be coupled to a further member such as, for example, a terminal board or further connector by means of a tongue portion coupled to the base member 22, such as indicated for example at in FIG. 3.
  • a further member such as, for example, a terminal board or further connector by means of a tongue portion coupled to the base member 22, such as indicated for example at in FIG. 3.
  • the particular coupling means illustrated therein is shown as an apertured tongue member, a forked tongue, tab, or tab receiving receptacle may-altematively be employed to effect a similar result.
  • An electrical connector comprising: a base member formed from electrically conducting ductile metallic material and having an inner surface, an outer surface, and a first thickness defined by the spacing between said inner surface and said outer surface; a series of generally elongate selectively spaced grooved portions arranged in a predetermined pattern within said base member inner surface, the bottom of said grooved portions extending below said base member inner surface a predetermined depth and the sidewalls of said grooved portions extending upwardly normal to the plane of said inner surface, the spacing between the bottom of said grooved portions and said base member outer surface defining a second thickness thereat, said second thickness being less than said first thickness; a series of selectively deformable teeth extending outwardly from said base member inner surface a predetermined distance, said teeth being arranged in pairs, each tooth of said pair extending along substantially the length of and adjacent to an associated one of the pair of opposing sidewalls of an associated one of said grooved portions, said teeth having convex exterior surfaces defining the sides thereof, said exterior sur faces converging to a sharp
  • An electrical connector as defined in claim 1 further comprising means for coupling said base member to a further member.
  • each of said grooved portions is planarly disposed generally parallel to the plane of said base member inner surface.
