Definitions

  • connection or disconnection
  • connection or disconnection
  • This feature may be required to prevent damage to the components being connected.
  • US-A-4,022,519 teaches a connection device with a heat-recoverable characteristic but again mechanical force is required to open the connector and the device is limited to single line contact.
  • US-A-3,727,173 discloses a zero insertion force connector but again it does not solve the problem set out above because the nature of the device is such that it is only suitable for single line contact. Multiple lines could be connected by using a multiplicity of such connectors.
  • US ⁇ A ⁇ 4,396,224 teaches the use of a heat- shrink sleeve for engaging pins in a grid network on a printed circuit board but this is not an electrical connector intended to be made and interrupted at will.
  • US-A-3,740,839 provides teaching similar to that of US ⁇ A ⁇ 3,727,173.
  • an electrical connector comprising a first strip having an axially elongated hollow split tube formed at one edge of the strip, with the tube axis and the split parallel to said strip edge, the strip having extending along it at least one electrical conductor that leads to a respective exposed inwardly-facing contact on the split tube, characterised in that the split tube is constructed in substantially concentric layers, of which one layer comprises
  • a heat recoverable member arranged to change the radial dimension of the tube and thereby open or close said split, said member being formed from shape memory metal having a deformable state below a transition temperature and a memory state above the transition temperature, and being capable of being deformed when said metal is in its deformable state to achieve one dimension of the split, a change from its deformable state to its memory state recovering said member to its non-deformed shape to achieve another dimension of the split;
  • another layer of the tube comprises spring means in operative association with said heat-recoverable member, said spring means and said heat-recoverable member in one condition providing unobstructed access for a second strip or tongue that may be inserted into said hollow split tube radially through the split, and in another condition closing the split sufficiently to grip the second strip or tongue that may have been so inserted, said spring means exerting a radial force against said heat-recoverable member to deform said heat-recoverable member when said metal is in its deformable state, said heat-recoverable member being capable of overcoming said spring force when said metal is changed from its deformable state to its memory state thereby recovering to its non-deformed shape to change the dimension of said split; and
  • a plurality of parallel spaced electrical conductors along said first strip extend in a direction generally at right angles to the axis of said split tube to terminate in a plurality of inwardly-facing corresponding exposed contacts disposed to make electrical contact with said second strip or tongue, if said second strip or tongue has been inserted through the split of said split tube, when the tube layers are in the condition in which the split is closed to grip the second strip or tongue.
  • the invention is preferably employed in a multipin electrical connector including a male member having a plurality of conductors thereon extending longitudinally in parallel and a female member that includes a split tube to receive the male member.
  • a plurality of parallel conductors on the female member extend to the inside of the split tube which receives the male member and are spaced to correspond with the conductors along the male member.
  • the male member has an enlarged edge that is insertable into the split tube and each conductor on the inside of the split tube faces a corresponding conductor on the inserted portion of the male member.
  • the split tube includes Nitinol or some other shape memory material which is biased open (or closed) and which, upon heating to a transition temperature, changes dimension to engage (or disengage) the inserted male member.
  • Such a connector features zero insertion force, high strength, close conductor spacing, and high shock resistance.
  • the conductors along the male member contact the corresponding conductors on the split tube.
  • the invention pertains to an electrical connector for coupling the end portions of two strips together.
  • the first strip has the split tube forming one end edge thereof, the split of the tube being selectively opened and closed.
  • the end portion of the second strip is inserted into the split when the tube is open, whereupon the tube may be closed to effect coupling of the two strips.
  • parallel conductors on both the upper surface and the lower surface of the second strip are couplable to corresponding conductors of the first strip by closure of the split tube thereagainst.
  • the conductors along the upper surface of the second strip are separate and independent from the conductors along the lower surface thereof.
  • the conductors along the first strip can similarly comprise (a) an upper plurality of conductors that can close against conductors along the second strip upper surface and (b) a lower plurality of conductors independent of the upper plurality that can close against conductors along the second strip lower surface.
  • a double connector is provided wherein a pluralityofconnections can be effected in an upper plane separately and distinct from connections effected in a lower plane. That is, where x conductors are provided along the upper surface and x conductors are provided along the lower surface of the second strip, 2x connections can be made.
  • conductors along the upper surface of the second strip extend into the conductors along the lower surface.
  • the upper plurality of conductors of the first strip may extend into the lower plurality of conductors.
  • Hybrid embodiments which vary from the above two embodiments-the single connector and double connector-may include maintaining some of the conductors on the upper surface of the second strip independent of the conductors on the lower strip while other conductors on the upper strip extend into conductors on the lower strip.
  • all conductors along the upper surface may extend into the conductors along the lower surface of the second strip whereas all conductors in the upper plurality of the first strip do not extend into conductors in the lower plurality. Accordingly, two sets of lines connected respectively to the upper plurality of the first strip and to the lower plurality of the first strip may be interconnected upon closure against the second strip, as well as connection being provided between the conductors on the first strip and second strip.
  • the shape memory metal may be a nickel titanium alloy. More specifically, it is preferred that the split tube comprise coaxial layers which include a shape memory layer, a stainless steel spring layer disposed about the shape memory layer, and a flexible plastic layer-into which the conductors are embedded-enclosing the split tube. Depending on how heat is applied to the shape memory layer, a heater element may be provided adjacent the shape memory layer along the portion of the flexible plastic layer which inscribes the split tube.
  • the edge of the second strip inserted into the interior of the split tube may be enlarged as already indicated.
  • closure of the connector may be performed by heating the shape memory layer to a characteristic transition temperature. It is, however, contemplated that opening of the connector may also be performed by heating the shape memory layer to a characteristic transition temperature. It is known that a shape memory metal in its memory shape displays high strength; thus the closure or opening to a memory shape results in a high strength configuration.
  • the connector 100 is shown including a first strip 102 which terminates in a split tube 104.
  • the split tube 104 is shown formed of a plurality of coaxial layers.
  • a flexible plastic layer 106 which serves to inscribe and circumscribe the split tube 104. That is, the flexible plastic layer 106 extends along a flat two-layer portion 107 of the first strip 102, passes circumferentially to an upper lip 108 whereupon the plastic layer 106 traces the inner surface of the split tube 104 to a lower lip 110. From the lower lip 110, the plastic layer 106 follows the lower outer circumference of the split tube 104 back to the flat portion 107 of the first strip 102.
  • the flat portion 107 comprises two plastic layers that lie against each other as a laminate.
  • the splittube 104 also includes a shape memory layer 112 about which is disposed another layer 114.
  • the layer 114 is preferably stainless steel.
  • the shape memory layer 112 and layer 114 are enclosed by the flexible plastic layer 106.
  • a flexible heater 120 Provided along the inscribing portion of the flexible plastic layer 106 is a flexible heater 120 of a construction known in the art.
  • the heater 120 is adjacent the shape memory layer 112 to direct heat thereto.
  • each conductor 130 through 134 extends along the flat portion 107 to follow an outer circumscribing path toward and around the upper lip 108.
  • Each conductor 136 through 140 follows a similar path along the lower layer 128 of the first strip 102.
  • the conductors 130 through 134 along the upper layer 126 may or may not extend into corresponding conductors 136 through 140 along the lower layer 128 depending on embodiment.
  • the conductors 130 through 140, as well as the heater 120, are embedded in the flexible plastic layer 106 to enhance durability, shock and impact resistance, integrity of structure, and strength and to maintain the relative positions of conductors and heater strips. That is, the conductors 130 through 140 and heater 120 are covered by plastic layer 106. To expose the conductors to permit electrical contact therewith-as by pressing another conductor thereagainst-windows are provided in the plastic layer 106 where contact is to be made. As described below, the windows expose at least those portions of the conductors 130 through 140 along the upper lip 108 and the lower lip 110. The space therebetween, it is noted, defines the split of the tube 104 between which a second strip 150 is insertable.

  • the edge 176 is enlarged by inserting a rod or the like between the two layers 150 and 152 at the fold therebetween). By enlarging the edge 176, the two strips 102 and 150 cannot be pulled apart after the split tube 104 is closed with the edge 176 inserted.

  • the connector 100 in Figure I is shown with the split tube 104 closed.
  • the split tube 104 is deformed to open the split.
  • the shape memory layer 112 may serve to either open the tube 104 from a closed position or close the tube 104 from an open position. Whether the shape memory layer 112 acts to open or to close the tube 104 depends on the memory shape imparted to the layer 112.
  • the shape memory layer 112 comprises a material that can be formed to a predefined memory shape or configuration. After the memory shape is defined, the material can be deformed and, by bringing the material to a characteristic transition temperature, returned (or recovered) to the memory shape.
  • various plastics feature heat recoverable memory, it is preferred that the shape memory layer 112 be a metal which undergoes transition such as a nickel titanium alloy, or Nitinol.
  • Nitinol has a temperature above which the memory configuration is set. By holding the Nitinol to a given shape at such temperature (e.g. approximately 900°F (482°C) for 55-Nitinol), the memory configuration becomes fixed. Nitinol also has a transition temperature range (TTR) below which the alloy is ductile and may be plastically deformed and above which recovery occurs.
  • TTR transition temperature range
  • Nitinol and similar alloys characterized with memory shape can be repeatedly deformed and recovered in alternation by applying pressure to the Nitinol when below the TTR and by heating the alloy to recovery temperatures thereafter.

  • the shape memory layer 112 acts to open the tube 104.
  • the tube 104 is closed by a spring force provided by the layer 114.
  • the spring force is sufficient to close the tube 104 when the shape memory layer 112 is ductile and soft (below the transition temperature of Nitinol, for example) but is overpowered by the shape memory layer 112 upon recovery thereof.
  • the tube 104 may be deformed closed by means of a tool, if the layer 114 is not desired or provided.
  • sample dimensions include: an outer diameter of .120 inches (0,305 cm) for the tube 104 when closed, a .020 inch (0,051 cm) thickness of layer 112, a .015 inch (0,038 cm) thickness of layer 114, an inner "diameter" of the tube 104 (when open) of .022 inch (0,056 cm) and a plastic layer 106 having dimensions of a conventional flexstrip.

Abstract

Un problème courant dans l'art de relier deux composants électriques est d'obtenir un couplage pratique et efficace à force d'insertion zéro entre les composants, notamment lorsqu'on doit relier une pluralité de conducteurs parallèles le long d'un composant avec une pluralité correspondante le long de l'autre composant. Le dispositif (100) et le procédé ci-décrits permettent de résoudre ce problème par application d'un bord de tube fendu le long d'un des deux composants électriques (100, 150), le tube fendu (104) contenant un matériau à mémoire de forme. Lorsque le tube fendu (104) est ouvert, le deuxième composant électrique (150) y est introduit et le tube fendu peut être fermé. Des conducteurs (130-140) le long du tube fendu (104) sont en contact avec les conducteurs correspondants (160-170) le long du deuxième composant (150) lorsque le tube (104) est fermé. Le matériau à mémoire de forme (112) dans le tube fendu (104) permet soit d'ouvrir (fig. III) le tube fendu soit de le fermer (fig. V) lorsque le matériau (112) atteint une température de transition caractéristique.
