Definitions

  • the present invention relates to the field of electrical connections and more particularly to interconnecting flat power cables.
  • US-A- 4,859,204 and US-A- 4,867,700 both published after the priority date of the present invention, disclose a transition adapter which is crimped onto a flat power cable by penetrating the insulation covering the cable's conductor and also shearing through the conductor at a plurality of locations.
  • the cable is of the type entering commercial use for transmitting electrical power of for example 75 amperes nominal, and includes a flat conductor 2.54 cm (one inch) wide and about 0.51 mm (0.020 inches) thick with an extruded insulated coating of about 0.1 to 0.2 mm (0.004 to 0.008 inches) thick over each surface with the cable having a total thickness averaging about 0.86 mm (0.034 inches).
  • One embodiment of the transition adapter is stamped and formed of sheet metal and in one embodiment includes a pair of opposing plate sections disposed along respective major surfaces of the cable and including opposing termination regions extending transversely across the cable.
  • Each terminating region includes a transverse array of alternating shearing wave shapes and relief recesses of equal width, the relief recesses defined by arcuate projections extending away from the cable-proximate side, and the wave shapes extending outwardly from the cable-proximate side and toward relief recesses in the opposed plate section.
  • Each shearing wave shape has a transverse crest between parallel side edges, and the side edges of the corresponding relief recesses are associated with the wave side edges to comprise pairs of shearing edges, preferably with zero clearance.
  • the crests of the wave shapes initiate cable shearing by their axially oriented side edges cutting through the cable insulation and into and through the metal conductor.
  • the wave shapes extrude the sheared cable strips outwardly into the opposing relief recesses as the shears propagate axially along the cable for limited distances, forming a series of interlocking wave joints with the cable while exposing newly sheared edges of the cable conductor for electrical connection therewith.
  • inserts of low resistance copper fastened to the outwardly facing surface of the plate sections at the terminating regions are respective inserts of low resistance copper.
  • the inserts have adapter-facing surfaces conforming closely to the shaped outer surface of the terminating region, with alternating wave shapes and apertures disposed outwardly of and along the adapter wave shapes and relief recesses.
  • the wave joints are within the insert apertures, and the sheared edges of the adjacent conductor strips and of the adapter wave shapes which formed the sheared strips are adjacent to side surfaces of the copper insert apertures.
  • a two-step staking process is preferred: in a first step the wave joints are split axially so that portions of each arcuate shape of both adapter plate sections are forced inwardly against the adjacent sheared conductor strip of the respective wave joint to define spring fingers whose ends pin the conductor strip against the opposing wave crest to store energy in the joint; and in the second step a staking process deforms the insert between the sheared strips to deform the copper against the sheared conductor and wave shape edges, forming gas-tight, heat and vibration resistant electrical connections with the cable conductor and with the transition adapter, so that the inserts are electrically in series at a plurality of locations between the conductor and the adapter.
  • a contact section is integrally included on the transition adapter enabling mating with corresponding contact means of an electrical connector, or a bus bar, or a power supply terminal, for example, and can include a plurality of contact sections to distribute the power to a corresponding plurality of contact means if desired.
  • a housing or other dielectric covering can be placed around the termination as desired.
  • connectors for such tap and splice interconnections be compact, comprise relatively few parts and be relatively easy to assemble.
  • the present invention consists in a method of interconnecting a pair of flat power cables each having at least one flat conductor therein, comprising the steps of: stacking a selected section of one flat cable over a selected section of the other with the conductors mutually parallel and aligned in a pair or pairs to be interconnected; and applying to said stacked cable sections at least one pair of upper and lower conductive interconnecting structures to the upwardly facing and downwardly facing surfaces of said stacked cables so that an array of conductor-engaging projections of each upper and lower structure at least deflects respective conductor strips out of the planes of the cables into respective opposing recesses of the opposing structure and side edges of said projections simultaneously engage exposed edges of the conductor strips thus electrically engaging with portions of the paired conductors of said cables and electrically interconnecting said paired conductors.
  • the invention enables the electrical interconnection of one dual (or single) conductor flat power cable to another, forming a splice or a tap interconnection between the cables which mechanically joins the cables and electrically interconnects the respective ones of the pairs of cable conductors or the single conductors. It enables the provision of such an interconnection utilising a minimal number of separate parts and is relatively easy to apply, requiring minimal cable preparation. Moreover, it enables the production of a splice or tap interconnection which defines a compact envelope upon completion, having minimal height, width and length. The splice or tap interconnection may compensate for at least a limited range of cable thicknesses.
  • the cables are first prepared by punching a longitudinal slot through the insulation of the medial strip (or center) of each cable at the desired interconnection site.
  • the cables are then stacked with the slots aligned and the associated conductors to be interconnected being adjacent each other in pairs.
  • Two pairs of upper and lower conductive interconnecting structures which are wave shape structures are then aligned vertically with the respective associated pairs of conductors, the upper structures being aligned with the associated lower structures and the pairs being spaced from each other at the vicinity of the cable slot.
  • the spaced-apart pairs of upper and lower wave shape structures are pressed together into the cable portion therebetween, shearing strips of the conductors to be interconnected and pressing alternating ones of the strips above and below the planes of the cables and exposing newly sheared conductor edges to be electrically interconnected by metal of the structures.
  • the wave shape structures would press previously tool-sheared conductor strips out of the cable planes.
  • Each structure may comprise an adapter member and an insert member.
  • the adapter member is disposed immediately against the insulated upper or lower cable surface, while an associated insert member is secured along the cable-remote surface of the adapter member.
  • Each adapter member includes an array of wave shapes extending toward the cable surface and defining shearing members, alternating with arcuate shapes extending away from the cable surface defining relief recesses to receive thereinto the wave shapes of the opposing adapter member and the conductor strips pressed outwardly thereby upon shearing during the interconnection process.
  • Each insert member is of low resistance metal such as copper and is secured to the cable-remote surface of the associated adapter member, and has an adapter-facing surface conforming closely to the cable-remote adapter surface and including corresponding wave shapes between which are relief apertures in which the arcuate relief shapes of the associated adapter member are disposed.
  • the adapter wave shapes Upon cable interconnection, when the upper and lower structures of each pair are pressed together, the adapter wave shapes will shear the cables (unless the cables are previously sheared) and press the sheared conductor strips into the opposing relief recesses of the opposing adapter and also into the insert relief apertures in which the opposing arcuate relief shapes are disposed.
  • the side walls of the relief apertures will thus be disposed adjacent the sheared conductor edges and also the side edges of the wave shape of the opposing adapter member, defining interlocking wave joints.
  • the wave joints are split by being struck by blades of an apparatus extending through the relief apertures of the inserts; then the outwardly facing surfaces of the inserts are staked at the wave locations to deform the low resistance metal laterally outwardly and tightly against the adjacent sheared edges of the conductor strips forming gas-tight and heat and vibration resistant electrical connections therewith, as disclosed in US-A- 4,859,204.
  • the wave splitting and insert staking may optionally be performed simultaneously.
  • the completed interconnections of the pairs of conductors by the pairs of structures at the interconnection site are then preferably placed within housing means such as a pair of housing covers secured together, providing protection of the terminations and also providing insulative structure around all exposed conductive surfaces to prevent inadvertent engagement therewith by other particles.
  • the housing also preferably includes internal wall sections extending between the pairs of wave crimp structures and through the longitudinal cable slots to assure insulation between exposed metal of the interconnectors and the cable conductors, thus assuring that the interconnections remain assuredly isolated from each
  • the cables need not be prepunched.
  • the two upper structures are initially integrally joined by a spaced pair of ligatures of their adapter members extending across a medial region between the separate insert members, as are the two lower structures, which reduces by half the number of separate parts and simplifies handling, alignment and assembly.
  • tooling of the apparatus punches the slots through the cables and simultaneously shears away the ligatures of both the upper and lower joined structures, thus separating and electrically isolating the cable-applied upper and lower structures into separate interconnecting structures, after which wave splitting and insert staking is performed as before.
  • Each conductive interconnecting structure may include integral means to lock the upper and associated lower structures of each pair together after cable interconnection.
  • the inserts may have defined adjacent at least one of the relief apertures a pocket extending laterally therefrom, into which metal of an adjacent wave shape of the adapter of the opposing interconnecting structure will be deformed during the staking process, thus locking the structures together and providing mechanical integrity to the interconnection.
  • the adapters have tabs to extend through corresponding recesses of the opposing adapters after which the tabs are bent over to lock behind the adapter of the opposing structure, thus locking the structures to each other about the cables.
  • flanges of the upper and lower structures extend outwardly beyond both lateral edges of the cables and converge, the rivets are placed through aligned holes through the pairs of adjacent flanges and staked to lock the structures to each other sandwiching the cables therebetween.
  • the portions of the other cable conductors disposed between the structures but not being interconnected by the structure are unsheared by the structures but are preferably deflected out of the plane of the cables to relieve stress at the interconnection site.
  • each adapter has a shearing half and a non-shearing half;
  • the shearing half of both the lower and upper adapters of the pair includes a transverse array of wave shapes extending toward the cable surface and defining shearing members, alternating with arcuate shapes extending away from the cable surface defining relief recesses to receive thereinto the wave shapes of the opposing adapter member and the conductor strips extruded thereby upon shearing during the interconnection process;
  • the non-shearing adapter half of one of the lower and upper adapters includes a single continuous wave having a transverse width greater than the width of the conductor not to be sheared, to deflect a transverse portion of that conductor out of the plane of the cable, while the non-shearing half of the other adapter includes a single arcuate relief recess to receive thereinto the single wave of the opposing adapter and the nonsheared conductor portion deflecte
  • FIGURE 1 and 2 illustrate an interconnection of a first flat power cable with a second such cable, which may be single or dual conductor; the interconnection shown is a tap connection 10 between a main dual conductor flat cable 12 and a tap cable 14 of similar construction.
  • the interconnection of the present invention may also be used to splice together a pair of flat cables.
  • the housing assembly can comprise dielectric upper and lower housing members 16,18 which are secured together to at least provide insulation and physical protection of the cable interconnection site.
  • Housing members 16,18 are shown being hermaphroditic and securable together by semicylindrical posts 20 at diagonally opposed corners force-fittable into corresponding semicylindrical apertures 22 of the other housing member, where apertures 22 include engaging ribs 24 protruding radially into the apertures which become plastically deformed to firmly hold the posts in the apertures, as disclosed in US-A- 4,781,615.
  • Housing members 16,18 may be molded for example of thermoplastic resin having heat resistant properties.
  • housing members 16,18 may be securable together by means of latches as shown in Figures 11A and 11B.
  • Figure 1A illustrates a typical cross-section of a dual conductor flat power cable 12 wherein a pair of flat conductors 26,28 have an insulative coating 30 extruded therearound and defining a medial strip 32 between the conductors; cable 14 has identical construction. While the present disclosure is shown and described with respect to dual conductor cables, it is easily seen that the same terminal and methods are usable with single conductor cables.
  • FIG. 1 A first method of interconnection is shown and described in Figures 2 to 8C while a second method is shown in Figures 9A to 9C.
  • two interconnecting structure assemblies 34,36 are shown each of which interconnects respective ones of the conductors of the main and tap cables, while sandwiching both cables therewithin.
  • Assembly 34 electrically interconnects conductor 26 of main cable 12 with conductor 38 of tap cable 14.
  • Assembly 36 will electrically interconnect conductors 28,40 when pressed together against the cables.
  • Cables 12,14 are previously prepared for termination by having punched therethrough vertically aligned elongate slots 42,44 along the medial strips thereof, removing at least most of the width of the medial strips.
  • Medial slots 42,44 permit an axially extending barrier wall 46 of the housing members 16,18 to extend therethrough providing dielectric material between the interconnecting structures 34,36 after termination to assure electrical isolation of the circuits after interconnection.
  • Barrier wall 46 may comprise respective wall sections of both members 16,18 slightly offset from center to permit passing by each other during assembly of housing members 16,18 about the interconnection site. Slots 42,44 also enable registration tooling of the termination apparatus (not shown) to accurately locate and hold the cables in position during termination.
  • the interconnections occur at sides of each of a plurality of alternating upper and lower wave joints, upper wave joints 50 being visible in the Figure.
  • Figure 3 represents a simplified cross-section through interconnecting structure assembly 34, showing the plurality of upper wave joints 50 alternating and interlocking with lower wave joints 52.
  • Wave joints 50,52 are similar to the type disclosed in US-A- 4,859,204 and US-A- 4,867,700.

  • Insert members 64,84 may be for example of dead soft Copper CDA 110 generally about 1.68 mm (0.066 inches) thick which is nickel underplated and silver plated, preferably, and treated for tarnish resistance.
  • Adapter members 62,82 are designed to be hermaphroditic, as are insert members 64,84 and also housing members 16,18, thus simplifying inventory and assembly by requiring fewer different parts to establish the tap or splice connector 10.
  • the interconnection regions of the upper and lower assemblies 60,80 are preferably intermatable with each other when opposed, with the wave shapes precisely offset and opposed from relief recesses when applied to the cables.
  • each insert member is secured to its associated adapter member to be easily handled as a unit; such securing may be by force-fitting of the arcuate adapter relief shapes within the insert relief apertures; alternatively the inserts may be slightly prestaked as disclosed in US-A- 4,859,204.
  • the interconnection region of upper adapter 62 includes a pair of downwardly protruding wave shapes 66 each including a wave crest 68, alternating with a pair of upwardly directed arcuate shapes 70 having widths identical to the width of a wave shape 66 and defining relief recesses 72.
  • the array of wave crests 68 and alternating relief recesses 72 is to be oriented transversely with respect to the cables.

  • the wave crests 68,88 have been designed and dimensioned with respect to the nominal cable thicknesses so that the newly sheared edges 110 (see Figure 3) of the sheared conductor strips are moved past the vertical side edges of the wave shapes of the opposing wave shapes and past substantial vertical areas of the side surfaces of the wave shapes of the opposing inserts. This is indicated in Figure 6 by the wave overlap area 112, and is best seen in Figure 3 where newly sheared conductor edges 110 can best be identified.
  • the cables can be sheared by tooling at locations corresponding to wave shape edges to define the conductor strips which may then be pressed out of the plane of the cable by the adapter wave shapes for the previously sheared conductor edges to be disposed adjacent the metal side edges of the adapter wave shapes and the side walls of the insert wave shapes.
  • the interconnecting structures are preferably adapted to provide a positive self-locking means after termination, whereby the upper and lower assemblies positively lock to each other thus securing themselves tightly to each other with the cable portions clamped therebetween; the mechanical fastening attained by the self-locking means thus protects the terminations and their gas-tight interconnections against strain and vibration.
