Definitions

  • ABSTRACT Electrical connecting device comprises a generally V- shaped member having wire receiving slots extending into corresponding side edges which are adjacent to the bight of the V.
  • the plate sections of the V are preferably kinked in alignment with the slots. Upon insertion of a wire, the plate sections are resiliently stressed by the wire in a manner to cause them to move towards each other. Additionally, the individual plate sections may be flexed by stressing of the kinked sections in the manner of a cylindrical spring.
  • This invention relates to electrical connections of the type in which a conductor is forced into a slot having a width such that the edges of the slot penetrate the insulation of the conductor and establish contact therewith.
  • slotted plate-type electrical connections have been widely used for several years and are being used to an increasing extent under a variety of circumstances.
  • the simpliest form of slotted plate-type connecting device comprises a flat metal plate having a slot formed therein which is adapted to receive the wire.
  • the portions of the plate member on each side of the slot are stressed in the manner of a rigid cantilever beam and by virtue of their stressed condition, electrical contact is maintained with the wire.
  • contact depends upon an extremely rigid spring system since the cantilever beams of the system are extremely stiff and capable of undergoing only limited elastic deflection.
  • the instant invention is specifically directed to the achievement of a slotted plate-type connecting device having improved spring systems for maintaining the electrical contact with the wire which permit the use of relatively thinner metal stock in the connecting device than has heretofore been practical.
  • the invention is directed to the achievement of a connecting device which is efficient in the sense that it has spring systems for establishing electrical contact which utilize the properties of the material from which the contact is made to a high degree.
  • the invention is further directed to the achievement of a connecting device which is inherently rigid and strong and which can be manufactured at a low cost to a high degree of precision.
  • the principles of the invention can be used in a wide variety of connectors and under a wide variety of conditions.
  • a further object is to provide a slotted platetype connecting device having improved spring characteristics.
  • a still further object is to provide a connecting device which can be manufactured from a wide variety of materials and from materials of differing thicknesses.
  • a further object is to provide an improved method of providing the wire receiving slot in a slotted plate-type connecting device.
  • FIG. 1 is a perspective view of one form of connecting device in accordance with the invention which is adapted to be mounted in a printed circuit board, this view showing the connecting device exploded from the printed circuit board and showing the lower portion of an insertion tool for inserting a wire into the connecting device.
  • FIG. 2 is a perspective view which is similar to FIG. 1 showing a wire inserted into the slots of the connecting device.
  • FIG. 3 is a plan view of the stamped blank from which the connecting device of FIG. 1 is formed.
  • FIG. 4 is a plan view of the blank after it has been kinked in order to size the wire receiving slots.
  • FIG. 5 is a top plan view of the connecting device of FIG. 1 in its normal condition and prior to insertion of the wire.
  • FIG. 6 is a view similar to FIG. 5 but showing the connecting device after insertion of the wire and illustrating one mode of stressing the connecting device.
  • FIG. 7 is a fragmentary view of one of the plate sections of the connecting device of FIG. I in its normal condition.
  • FIG. 8 is a view similar to FIG. 7 but showing the plate section after insertion of the wire, this view illustrating another mode of stressing the connecting device by the wire.
  • FIG. 9 is a top view of an embodiment of the invention adapted for connecting a tap-wire to a throughwire splice.

  • FIG. 11 is a view of the connector of FIG. 10 showing the parts in assembled relationship.
  • FIG. 12 is a perspective view of an electrical contact pin having a connecting device in accordance with the invention integral therewith.
  • FIG. 13 is a view showing an alternativeform of contact pin provided with a connecting device in accordance with the invention.
  • FIG. 14 is a fragmentary perspective view of a multicontact electrical connector containing contact pins of the type shown in FIG. 12, this connector being adapted to connect the conductors of a ribbon-cable to conductors on a printed circuit board.
  • FIG. 15 is a fragmentary perspective view of a printed circuit board having connecting means in accordance with the invention mounted thereon.
  • An electrical connecting means 2 in accordance with the invention comprises a generally V-shaped member of conductive sheet metal having divergent platesections 4, 6 which are integral with each other at a bight 8.
  • the connecting means of FIG. 1 has an integral mounting post 10 extending from the bight which is adapted to be inserted through a hole 11 in a printed circuit board 13 and soldered to a conductor on the underside of the board.
  • Wire receiving slots 12, 14 in the plate sections 4, 6 extend inwardly and parallel to the bight 8 from the upper side, as viewed in FIG. 1, of the connecting member, the edges 16, 18 of this side sloping towards the slots in order to guide the wire into the slots during insertion.
  • Each plate section has a generally semi-cylindrical kink 20 which extends from the inner end 15 of its slot to the lower side of the connecting member.
  • these kinks serve as resilient springs when the wire is inserted into the slots and contribute to the contact force at the electrical interface of the wire in the connecting means.
  • these kinks permit the manufacture of connecting members with extremely narrow slots for the reception of fine gauge wires.
  • one of the slots, l2, 14 has a width which is substantially less than the diameter of the conducting core 22 of the wire and the'other slot has a width which is substantially equal to or greater than the diameter-of the core of-this wire so that a good electrical contact is obtained at the narrow slot and a mechanical strain relief. for the wire is provided by the wider slot.
  • One form of insertion tool 26 for inserting the wire into the slots has a shank 28-and a central triangular wire pusher 30 which is adapted to move between the opposed faces of the plate sections 4, 6. Additionally,
  • the wire will be displaced downwardly between the opposed faces of the plate sections 4, 6 and the insulation of the wire will be penetrated as shown in FIGS. 5 and 6.
  • Connecting devices in accordance with the invention can be manufactured of any suitable conductive sheet metal such as brass or phosphor bronze.
  • the specific device shown in FIG. 1 is manufactured by simply stamping the blank 2, FIG. 3, with the slots 12, 14' of the blank being substantially wider than the slots in the operation has the effect of moving the sides of the slots relatively towards each other and is carefully controlled to produce the desired widths in the slots.
  • This method of manufacture is distinctly advantageous for the reason that there is for any given stock metal, a lowerlimit to the width of an opening that can be punched in the stock.
  • a lowerlimit to the width of an opening that can be punched in the stock As a general rule of thumb, it can be assumed that it is impractical to punch an opening in sheet metal which has a width that is less than the thicknessof the sheet metal; if smaller, openings are punched, excessive tool wear and tool breakage result to an extent that an operation becomes impractical.
  • Slotted plate-type connecting devices frequently must be provided with extremely narrow slots for fine wires; for example, an AWG 32 wire has a diameter of about 0.008 inch and would therefore require a slot having a width of about 0.006 inch orless for effective electrical contact.
  • the V-shaped connecting device of FIG. 1 may be stressed upon insertion of the wire in a manner such that the two-plate sections are pulled bodily towards each other so that these plate sections move from'their normal positions (FIG. 5) to the position shown in FIG. 6.
  • This movement of the plate sections towards each other takes place because of the fact that the wire receiving slots l2, 14 are not in alignment with each other but are located such that there center lines extend obliquely of each other and intersect as shown inFIG. 5.
  • the wire moves down-' wardly'into the slots, it engages the sharp corners of each slotand tends to move the plates towards each other as shown in FIG. 6.
  • the plate sections thus have a tendency to return to their normal positions after the wire has been inserted and exert a continuing interface pressure on the wire.
  • This flexure of the plate sections as units towards each other thus provides one mode of spring loading and gives rise to one source of contact force.
  • FIGS. 5-8 show the deformation phenomena in exaggerated form for purposes of illustration.
  • theflexure of the plate sections towards each other and the displacement of the plate portion 34 may or may not ba apparent upon visual inspection but the forces which give rise to these deformations will tend to cause the movements illustrated in the drawing.
  • a given connecting device in accordance with the invention will not necessarily be significantly deformed in both modes illustrated and one mode of deflection'may be of more significance than theother.
  • the actual behavior of the connecting device will be dependent upon suchfactors as the thickness and physical properties of the metal stock, the wire size relative to the slot widths and the stiffness of the kink 20.
  • connecting devices of the type shown in U.S. Pat. No. 3,388,370 can to advantage be provided with kinked plates for purposes of accurate manufacture of the slot width and the achievement of the spring effect of the kink 20.
  • An individualplate section having a wire receiving slot therein may be stressed, upon insertion of a wire into the slot, in a manner such that the two parts of the plate section would move apart but would remain co-planar; in other words, insertion of the wire might cause partial flatteningof the kink 20 rather than pivoted movement of one part of the plate section.
  • the .kink functions as a spring which stores energy for mainlived low resistance electrical connection.
  • the V-shape of the connecting device is advantageous in that it is a relatively rigid and stable structural shape even if the counting device is formed of thin stock metal. As will be explained below, this V-shape is well adapted to close spacing of adjacent connecting devices on a printed circuit board and in a multi-contact connector.
  • FIG. 9 shows a device for connecting a tap wire 40 to a through wire 38, this connecting device comprising two connecting means 42, 44 of the type previously described which are integral with each other along one edge of each plate-section at 46.
  • a connecting device as shown in FIG. 9- can be manufactured by simply stamping the required slots in a blank and bending the blank to form the offset individual connecting means for the tap wire and the through wire.
  • FIGS. 10 and 11 show a multi-contact connector for forming butt-splice connections between three pairs of wires extending axially towards each other.
  • the connector contains three separate W-shapedconnecting arate connecting means 50, 52 which are integral with each other by means of a connecting bight 54.
  • the housing base section 56 has upstanding sidewalls 58 and barriers 60 extending between, and parallel to, the sidewalls to form three separate compartments, one for each connecting means 48.
  • the cap section 62 has integral depending flanges 64 with inwardly directed lower ends 66 that are adapted to snap to grooves 68 in the sidewalls 58 of the base section.
  • Cap section 62 also has depending ribs 70 which are located such that they will push the wires into the splice connectors when the cap section is assembled to the base section.
  • the housing may be of any suitable insulating material such as a firm thermo-plastic.
  • FIG. 12 shows an electrical contact pin 71 having an enlarged intermediate section 76 which is connected by a neck 74 to a connecting means 72 in accordance with the invention, the connecting means being oriented relative to the axis of the pin such that it is adapted to receive a conductor 78 extending transversely of the axis of the contact pin.
  • a terminal of this type can be used in an electrical connector as described in FIG. 14 below.
  • FIG. 13 shows a pin 71a having a connecting means 72a integral therewith, this connecting means being oriented so as to receive a wire extending coaxially with respect to the contact pin.
  • FIG. 14 shows a multi-contact electrical connector in accordance with the invention for connecting the individual conductors 82 of a ribbon-cable 80 to the conductors 98 of a printed circuit board 94.
  • the cable 80 contains a plurality of parallel connectors, each of which is surrounded by plastic insulation 84 that extends between adjacent conductors as a web 86.
  • the connector of FIG. 14 comprises a block 88 of insulating material having cavities extending therethrough in which electrical contact pins 71 are mounted.
  • the con- 6 nectmg means 72 on the upper ends of the contact pins are arranged in a row with the spacing between adjacent connecting means of adjacent terminals being equal to the spacing between adjacent conductors 82 of the cable.
  • FIG. 14 illustrates a further advantage of the invention in that the individual connecting means 72 can be nested within each other and close spacing of the contact terminals in the block can be achieved, notwithstanding the fact that the plate sections are of substantial width.
  • FIG. 15 shows a printed circuit board 94 having a plurality of connecting means 2 in accordance with the embodiment of FIG. I mounted thereon.
  • the post portion of each connecting means extends through the printed circuit board and is soldered to an electrical conductor 98 on the underside of the board.
  • the connecting means 2 are nestedwithin each other so that there is a minimum of space separating adjacent connecting means 2. This view thus illustrates the fact that connections can be made with printed circuit board conductors 98 that are extremely close to each other.
