Definitions

  • This invention relates to an electrical wiring device and more specifically to a wiring device having insulation-piercing interconnecting element bonded to conductor.
  • Insulation piercing termination is well known in the prior art.
  • the tines diverge laterally from each other, have insulation pierce tips at their free ends, and include conductor engaging corners diverging outwardly from the body. During termination the corners engage the conductor thereby creating a mechanical contact between connector and conductor, Such an arrangement might, however, be susceptible to increasing contact resistance during extreme service conditions.
  • United States 3,615,283, issued October 26, 1971 to D. D. Long discloses conductors with loose-fitting insulating jacket which are formed into terminal loops through a punching operation.
  • the punching process performed by a punch and a die, cuts away a portion of the insulation and is followed by the loop formation which involves the pulling of the conductor relative to its own insulation.
  • the resulting bare terminal loops, and the contacts formed with them are subject to the effects of the environment and the disclosed process is limited to individual wires of a cable having loose-fitting insulating jackets.
  • a similar process is disclosed in United States 3,636,991, issued January 25, 1972 to A. D. Webster.
  • Laser beam welding has been applied to spot welding very small wires, as described in "Lasers in Metalworking", American Machinist Special Report No. 679, July 1, 1975, and "Welding", American Machinist Special Report No. 698, September, 1977. See also, United States 3,534,462, issued October 20, 1970 to D. G. Cruickshank, et al., disclosing a method for bonding a plurality of leads to a workpiece utilizing laser beams shaped into a predetermined pattern; United States 3,718,968, issued March 6, 1973, to S. D.
  • An electrical connection comprising a terminal having tines on one end and an electrical contact on the other end, said tines defining a slot terminating in a base; an insulated electrical conductor in said slot having a portion bent back on itself forming a bight over the base of said slot such that a loop is formed, said loop being at least one conductor thickness high, said conductor being exposed at the apex of said bight; said one end of said terminal and the exposed apex of said bight being permanently bonded to form an electrical connection; and a dielectric body surrounding said connection, said body having an optional opening leading to said bight and havind an opening leading to said electrical contact at the other end of said terminal.
  • an electrical connector comprising insulated flat cable with a plurality of parallel electrical conductors encased in a uniform tight-fitting insulation; at least one connector assembly in electrical attachment to the cable, the assembly usually including insulating foundation and cover attached to each other and interconnecting elements mounted in said foundation in line array, there being usually one interconnecting element for each conductor in each assembly; each interconnecting element comprising a conductive blade having first and second ends, the first end formed as an insulation piercing forked contact and the second end is formed as an electrical terminal for plug-in service; the forked end or tines disposed in at least one plane normal to the flat cable; and the insulation-piercing end extending through the insulation of the cable such that a conductor is formed into a bight outside its insulation and in electrical contact with said first end, the apex of the bight being disposed between tines of the insulation piercing end and over the base of a slot therebetween.
  • the method of making the connector involves simultaneously penetrating insulated wire cable with a plurality of insulation-piercing interconnecting elements, simultaneously bottoming the conductors in the slots of the interconnecting elements, displacing the cable relative to the interconnecting elements so that a limited length of each of the bottomed conductors in the cable is outside the insulation causing the displaced conductors to be bent hack on themselves such that a loop is formed at least one conductor thickness high and the apex of the loop is a bight over the bottom of the slot in the interconnecting element, permanently bonding the bight to the interconnecting element by a laser beam or other appropriate bonding technique and covering the interconnecting elements with a dielectric housing to form an insulated connector suitable for plug in service.
  • the electrical connection of this invention is formed between an electrical conductor encapsulated in an insulation and a forked terminal having tines on one (the forked) end and an electrical contact on the other end.
  • the conductor is formed into a bight over the base of a slot defined by the tines. The conductor is exposed at the apex of the bight and there is a permanent bond between the terminal at or near its forked end and the conductor at or near its apex.
  • the bond is a metallurgical bond such as a weld made by laser welding. Mechanical crimping of the tines prior to welding is preferred.
  • Connector 1 of this invention is shown in FIG: 1 in assembled form terminating flat cable 2 which is comprised of a plurality of conductors 3. These are encapsulated in insulation 4 which ordinarily has the ridge and furrow external configuration shown and can be extruded or laminated into a unitary structure with the insulation 4 bonded to or in tight relationship with conductors 3.
  • the insulation 4 can be made from any of a variety of elastomeric or polymeric materials.
  • polyvinyl chloride is preferred but "Teflon" fluorocarbon resin (registered trademark of E. I. du Pont de Nemours and Company) can also be utilized.
  • Preferred conductors 3 are stranded and tinned, commercially-pure copper wire, approximately 26-32 gage (A.W.G.). However, any conductive material of any desired and functional gage can be used and the article of manufacture of the invention is adaptable to solid conductors as well.
  • a most preferred conductor is 28 A.W.G. (7 strands A.W.G. 36) manufactured by Ernst U. Engbring & Co., style No. 2651, FR1, 105°C having a conductor spacing on .050 centers.
  • Each conductor 3 is in electrical contact with an insulation-piercing interconnecting element 5 which is an elongated blade-like metal member and which transfixes insulation 4 on either side of a conductor 3.
  • the width of the blade in the plane of flat cable 2 is approximately the same as or slightly larger than the spacing between conductors 3. See FIG. 18.
  • FIG. 2 A single such element, known as the "single beam” type, is shown in FIG. 2. It has one leg 8 available for contact with a plug-in male unit (not shown). The blade-like shape has shoulders 3° which seat in tne bottom of T-slots, not shown, in foundation in 13 of connector 1. To provide an interconnecting element 5 for each conductor 3, the elements 5 are in staggered line array, thus accommodating the width of element 5 as can be seen in FIG. 1.
  • Elements 5 are preferably fabricated from cupro-nickel, a copper/nickel/tin alloy (such as 89/9/2, by weight) with, typically, 30 micro inch (0.75 micrometer) gold in contact area 138. Any other common connector material or plating can be employed.
  • each conductor 3 passes out of insulation 4 in close proximity to the side of element 5 and forms a tight bight 6 passing through and bottomed in slot 7 in element 5 and is external to the insulation (except that a small piece of insulation may be present under the bight. If present it will cushion the conductor 4 against the base of slot 7). The conductor 3 then returns in close proximity to the other side of element 5 into insulation 4.
  • each bight 6 is permanently bonded to its associated interconnecting element 5.
  • Bonding techniques include crimping, soldering, induction or resistance welding, thermocompression bonding, ultrasonic welding, electron beam and laser welding.
  • laser welding preceded by squeezing of the tines as will be discussed in greater detail below, is the bonding method utilized. It should be noted that the configuration of bights 6 and elements 5, extending normal to and external of the plane of flat cable 2, is particularly amenable to a variety of bonding techniques because the junction is accessible during the manufacturing process from both sides as well as from above.
  • Element 5 is further characterized by being forked, having two insulation-piercing tines or tips 9 and 10 disposed on either side of slot 7.
  • the preferred tips are arrowhead-like in form with the inner surfaces of the arrowheads forming a throat 11 which is proportioned to be slightly smaller than the original diameter of a conductor 3 and smaller than the greatest extent of the base of slot 7.
  • Insulation-piercing interconnecting elements 5 are mounted in foundation 13 of connector 1 (see FIG. 1). A preferred mode of accomplishing this is by mechanical insertion. Tabs 23 help lock elements 5 in place against the wall. Ultrasonic insertion and insert molding are alternative but less-preferred assembly modes.
  • each leg 8 functions as a female contact.
  • cavity 1 is preferably provided with a wall 38 shaped to support the male pin to be inserted.
  • Foundation 18 can be molded from any suitable reinforced plastics such as glass-filled polyester or polycarbonate.
  • the connector 1 has a cover or cap 20 which is attached bv suitable means to foundation 13 Can 20, molded from any suitable plastic, has a series of holes 21 each aligned to receive the ends of an interconnecting element 5 in an interference fit with the breadth of the element.
  • a cover or cap 20 which is attached bv suitable means to foundation 13 Can 20, molded from any suitable plastic, has a series of holes 21 each aligned to receive the ends of an interconnecting element 5 in an interference fit with the breadth of the element.
  • the insertion of the insulation-piercing ends of elements 5, carrying the tight bights of conductors 3, into holes 21 of cap 20 is carried out ultrasonically as will be discussed further below. This technique bonds cap 20 both to elements 5 encased in foundation 13 and to foundation 13 on the ends.
  • FIG. 15 shows cap 20 in the form used for termination near the end of flat cable 2, having internal edges 36 and external rounded edge 40.
  • Cap 20 can also function to cut and detach the ends of insulation 4 with knife edge 134 when the insulation extends beyond the ends of conductors 3 and beyond the outside edge of foundation 13.
  • Cap 20 and knife edge 134 electrically insulate the cut wire ends from inadvertent contact with external metallic parts during service.
  • the connectors shown in FIGS. 1, 5 and 6 are shown with cap 20.
  • FIG. 16 shows cap 20' in the form used for daisy chaining, i.e., where cable 2 contiues beyond cap 20' in both directions.
  • Cap 20' has internal edges 36 and 27. It may also be used for end termination.
  • This wiring device is a structure in which each element 5 and its contacting bight 6, preferably bonded to each other, is permanently assembled and is substantially encapsulated within cap 20. Furthermore, strain relief of the bonded junctions is achieved. Thus, when a strain is placed upon cable ? and transmitted to connector 1 at its end, the strain is relieved where conductors 3 are bent over internal edges 36. For a daisy chain termination, strain in both directions is accommodated by edges 36 and 37 (see FIG. 16).
  • tip-receiving holes 21 in cap 20 which are open ended, as shown in FIGS. 15 and 16.
  • This type cf construction permits insertion of test probes to check electrical continuity during the service life of the electrical wiring device.
  • internal holes or internal cavities closed to the outside can also be employed as shown in FIG. 17 where web 41 is molded into the structure.
  • FIG. 5 depicts interconnecting elements 5' formed with two legs 8' and 8"; a construction known in the art as a "dual beam".
  • Elements 5' are similar to elements 5 of FIG. 1 except in the formation of the female contact by legs 8' and 8".
  • foundation 13' is similar to foundation 13 except in the shape of cavity 17' which does not require the same shaped wall 38 of cavity 17. Cavity 17' has relieved shaped wall 38'.
  • FIG. 6 similarly shows insulation-piercing interconnecting elements 5", similar to elements 5 of FIG. 1 and 5' of FIG. 5 except in regard to the configuration forming the female contacts.
  • contact receptacles 22 are shown. These are of the type known as MINI-PV dual-metal receptacles (a trademark of E. I. du Pont de Nemours and Company). Wall 38" is modified to form a cavity 17" suitable for the enlarged contact.
  • the dual-metal receptacle is a disconnect contact for 0.025 inch square or round pins on minimum 0.100 inch centers and often provides higher reliability than the single or dual beam designs.
  • a receptacle for an edgecard is shown in FIG. 19.
  • the beams 56 grip the edge of the edaecard and contact strips on the surface of the edgecard.
  • the beams 56 are shown so that they will connect opposite sides of a printed circuit board to the same connector 3.
  • the beams 56 may be staggered and each connect a different circuit on opposite sides of a printed circuit board. Of course the number of such beams 56 is a matter of choice.
  • An insulation-piercing interconnecting element 5"' in FIG. 20 depicts a male pin 54 at one end for engagement with a suitable female receptacle an another electrical device.
  • FIG. 5 shows the sequence of terminating cable according to this invention.
  • FIGS. 7-12 show this terminating sequence.
  • FIG. 3 shows terminated cable with a single beam interconnecting element.
  • FIG. 7 An insulation-piercing interconnecting element 5' mounted in terminal base 13' is shown in cross-section in FIG. 7.
  • Foundation 13' is held in a suitably shaped base tool 24.
  • Flat cable 2 is disposed such that the array of elements 5', a staggered line described above but not shown in FIG. 7 for reasons of clarity, is normal to the plane of cable 2.
  • Insertion tool 25, in association with guiding means (not shown) holds cable 2 in this normal relationship and aligned so that each conductor 3 is approximately positioned above an associated slot 7 of an element 5'.
  • FIG. 8 depicts the beginning of relative notion between base tool 24 and insertion tool 25 in the disection of the arrows causes tips 9 and 10 of elements 5' to penetrate insulation 4 on either side of conductors 3, the tips 9 and 10 passing completely through insulation 4 and entering slot 26 of tool 25 as conductor 3 is funneled into throat 11 (best seen in FIG. 4).
  • Continued motion seats conductor 3 in the base of slot 7 (see FIG. 9).
  • a portion of insulation 4 (shown as 4' in FIGS. 4 and 14) may be caught between slot 7 and conductors 3 and acts as a stress dstributing member during further forming.
  • Insertion tool 25 shown in FIG. 13, has one slot 26 for each of the staggered rows of elements 5' and, aligned with the throats 11 of elements 5' which are centered between tips 9 and 10, there are semicylindrical slots 28 and 29 sized to accommodate conductors 3. It is preferred that face 3,0 of tool 26 be connected with slots 26 by double chamfers 31. These facilitate entry of conductor 3 into slots 28 and 29 and also provide for the necessary stressing cf insulation 4 which referring now to FIG. 11, is deformed to its extreme and breaks moving over the conductors 3 to a rest position, Tools of this type are employed in a variety of presses, details of press operation and the means by which the tools are attached or guided are well known.
  • FIG. 10 illustrates the effect of further relative motion between base tool 24 and insertion tool 25.
  • Tip 10 is shown completely moved into slot 26 and holes 28 and 29 are beginning to accommodate conductor 3. The beginning of the formation of a tight bight over slot 7 is also shown. Insulation 4 is thinned out above the top of the bight and is compressed below it.
  • FIG. 11 shows the complete formation of a tight bight through slot 7 over element 5' with the the wire exposed through the insulation.
  • Tool 25 is removed at this stage and hence not shown in this figure.
  • a multistrand conductor When a multistrand conductor is employed, it tends to assume the cross-sectional configuration shown in FIG. 4.
  • conductors 3 to interconnecting elements 5' in order to avoid or minimize the long range effects of corrosion and vibration.
  • Such bonding can be achieved by a variety of metallurgical bonding techniques.
  • the interconnecting element 5 is positioned in the foundation portion 11 of the dielectric housing so that when the conductor is located at the base of slot 7 it is bent back on itself forming a bight over the base of the tine.
  • a loop is thereby formed and the conductor is exposed, the loop having a height of at least the thickness of the conductor above the top of the insulation. Higher loops are acceptable up to a height limited by the practicable necessity of covering the inserted connector in a dielectric housing cover.
  • FIG. 3 Such a position is shown in FIG. 3.
  • the inserted conductor 3 is thereby bent back on itself forming a bight 6 over the base 7 of said tines.
  • the conductor is exposed from its insulation 4 at the apex of the bight 6.
  • This exposed conductor can then be bonded to the tine directly by a laser weld or can be crimped by the tines and then laser welded to form a permanent electrical bond as shown at 50° in FIG. 18.
  • each tight bight formed in conductor 3 over an interconnecting element 5' has been subjected to the action of a crimping tool 34.
  • This crimping tool is illustrated in FIG. 14 and comprises a series of appropriately spaced holes of controlled depth and having a blind conical base 35.
  • the conical base preferably has a 90° angle.
  • the holes are sized as shown in FIG. 14 so that opposing motion between tool 34 and base tool 24 causes the crimping of tips 9 and 10 together as shown by the phantom lines in FIG. 14.
  • strands 12 are mechanically held in place in slot 7 above insulation portion 4'.
  • the configuration shown by the phantom lines is schematic, in actual practice, the closure between the arrowheads is less uniform.
  • Metallurgical bonding produces permanent interface between conductors 3 and elements 5 leading to improved electrical continuity in service.
  • Laser welding is the preferred technique utilized in obtaining the electrical connection and wiring device of this invention.
  • metallurgical bonding is meant an electrical contact formed between interconnecting element and conductor in such a manner that some metal-metal fusion occurs. Such bonding is brought about by the application of some form of energy at or near the area where a rigid bond is to be former.
  • Metallurgical bonding techniques include a variety of welding methods such as laser beam welding.
  • LBW has several advantages over other welding methods, e.g., it does not require electrode contact or flux. LBW has high heat intensity and the beam impacts on a small area; these factors contribute to localized heating and rapid cooling resulting in a small heat-affected zone.
  • the highly collimated monochromatic beam of light generated in a laser is focused on a surface and is partially reflected, and partially absorbed.
  • Optimum welding performance depends on absorptivity, thermal conductivity, density, heat capacity, melting point, and surface condition of the metals to be joined as well as the characteristics of the laser such as power density, wave length and pulse length.
  • a technique favored for carrying out laser welding involves positioning the welder so that its beam is within 90° of perpendicular to the long axis of the interconnecting element 5 and is aligned with the center of slot 7 after crimping. Approximately 5 millisecond-pulse length of the laser, delivering 10-15 joules, can accomplish the -19- bonding of an element 5 to the corresponding conductor 3. Such an operation of the laser is said to be operating in the conventional mode. Either or both of tips 9 and 10 of interconnecting elements 5 are partially melted and flow over and between heated strands 12 of conductor 3 forming a metallurgical bond.
  • Both tinned and untinned wire can be welded to CuNi with a plused C0 2 laser.
  • Such welds can achieve junction resistances of from 0.05-0.30 milliohm and shear strengths of from 2.7-4.8 pounds to break.
  • an Nd YAG (yttrium aluminum garnet) plused laser is utilized for high speed multiple welds.
  • the most preferred laser weld is accomplished by contouring the laser beam and aiming it so that a significant portion of the energy falls upon the conductor. This appears to preheat the conductor so that good fusion is obtained.
  • the major portion of the beam is directed on the tines 9 and 10. They are melted and the melt contacts the exposed conductor and fuses to it.
  • the laser is employed using a circular beam shape with an overall diameter of 0.090 to 0.100 inch and a concentric high energy core ranging between 0.055 and 0.075 inch in diameter.
  • the core is centered on a point on the tines above conductor strands 12 approximately 0.020 to 0.025 inch and in line with slot 7 placing the strands on the edge of the beam core or within it.
  • This configuration provides good welds without destruction of the conductor using a Nd YAG laser operated in a pulsed mode with pulse energy levels of 10-15 joules.
  • beam shapes besides circular are known and adaptable to the welding process such as rectangular, square, figure "8", or modifications thereof such as concentric rings. Each may apply particular instances.
  • means to vary the beam dimensions include beam divergence, power and especially optics.
  • FIG. 18 shows a dielectric housing foundation 13 containing interconnective elements 5 passing in front of a laser beam after the pierced flat cable 2 has been bent over and the conductor 3 exposed in the bight 6 at the base of the tines.
  • the conductor is shown with the tines squeezed shown before the laser beam hits the tines and the bight 6 causing a metallurgical bond 50 to form. This bond makes the connection permanent.
  • cap 20 is installed and sealed to foundation 13. It is preferred to position cap 20 in a fixture under an ultrasonic horn so that elements 5 are aligned to enter holes 21 in cap 20 in interference fit for permanent attachment. Cap 20 can also be ultrasonically bonded to foundation 13 thereby yielding a connector assembly as shown in FIGS. 1, 5 or 6.
