Definitions

  • ABSTRACT Plunger means for use in connection with an extrusion tool or the like comprises a displaceable auxiliary plunger portion longitudinally slidable along a recessed portion of the main plunger and normally biased to a first position wherein its first end extends forwardly of the first end or front end of the main plunger.
  • the auxiliary plunger When suitably contacted, the auxiliary plunger may be displaced rearwardly so that its front end is generally coincident with the front end of the main plunger.
  • the resulting self-adjusting plunger assembly thus provides means for extruding differently sized connectors through a particularly sized orifice in an extrusion tool or the like.
  • the auxiliary plunger portion precedes the main plunger into the extruding orifice when used in connection with the smaller connector, thereby selectively restricting the size of the orifice to that commensurate with the smaller connector.
  • the larger sized connector will displace the auxiliary plunger portion rearwardly when contacted thereby so that both the main and auxiliary plunger portions operate to advance the connector through the extruding orifice.
  • Biasing means which may comprise a compression spring or the like is provided to return the auxiliary plunger portion to its initial position after being displaced rearwardly along the main plunger recessed portion.
  • an extrusion tool having a plunger, the end of which is bifurcated to provide a slight variation in the size of the plunger upon entrance into a tapered extrusion orifice.
  • This feature permits the plunger to follow a connector through the restrictively tapered orifice of the extrusion tool sufficiently to eject the connector from the exit end of the orifice while substantially filling the tapered orifice during the extrusion operation.
  • the extrusion orifice is designed to accept a connector having a fixed dimension and, accordingly, restrictively limits the use of the tool in applications where a plurality of connector sizes are to be employed.
  • a plunger arrangement comprising coaxially arranged outer and inner members, the inner member being telescopingly movable within the outer member and so positioned as to provide a pocket or recess therebetween for accepting a portion of the connector therein as the connector is extruded through the extrusion orifice of the extrusion tool.
  • the extrusion orifice of this tool is similarly dimensioned to accept only a single size connector and the versatility and convenience of the tool is therefore limited in essentially the same way as the first described device.
  • the invention overcomes the difficulties and limitations noted above with respect to prior art devices by providing a composite plunger arrangement operative in an extrusion tool or the like to permit the use of a single tool in conjunction with differently sized connectors in a manner more convenient, versatile, and economical than with such prior art devices.
  • the plunger means comprises a first or main plunger portion having a first end provided with a recessed portion adjacent which is disposed a second or auxiliary plunger portion longitudinally slidable along the recessed portion and normally biased towards a first position in which the front end of the auxiliary or second plunger portion extends forwardly of the front end of the main or first plunger portionL
  • the auxiliary plunger portion may be rearwardly displaced longitudinally so that its front end is substantially coincident with the front end of thefirst or main plunger portion to provide an essentially confor a connector having a transverse dimension essentially equal to the corresponding transverse dimension of the main plunger portion alone where the extruding orifice has a transverse dimension essentially equal to the combined dimensions of both the main plunger portion and the auxiliary plunger portion.
  • the second or auxiliary plunger portion is displaced rearwardly upon contacting a connector having a transverse dimension essentially equal to the corre sponding combined transverse dimensions of both the main and auxiliary plunger portion front ends and assumes a position essentially coincident with the front end of the main plunger portion so that the front ends of both the main and auxiliary plunger portions cooperate to advance the connector through the extruding orifice. It is therefore an object of this invention to provide improved plunger means for an extrusion tool or the like.
  • FIG. 1 is a side elevational view, partly cut away and partly in section, of an extrusion tool employing an improved plunger means constructed in accordance with the concepts of the invention.
  • FIG. 2 is a fragmentary side elevational view, in section, showing the details of a plunger means constructed in accordance with the concepts of the invention.
  • FIG. 3 is a fragmentary side elevational view, in section, showing the plunger means of FIG. 2 selectively advanced into the orifice of an extrusion tool.
  • FIG. 4 is a fragmentary side elevational view, in section, similar to FIG. 2, showing the initial relative positions of the plunger means of FIG. 2 and a given connector prior to extrusion.
  • FIG. 5 is a fragmentary side elevational view, partly cut away and partly in section, showing the elements of FIG. 4 in an advanced state of operation.
  • FIG. 6 is a fragmentary top plan view, partly cut away and partly in section, of the plunger means of the device of FIG. 2.
  • FIG. 7 is a front elevational view, in section, taken along the line 7-7 of FIG. 6.
  • FIG. 8 is a front elevational view, in section, similar to FIG. 7, but showing a further embodiment of plunger means constructed in accordance with the concepts of the invention.
  • FIG. 9 is a fragmentary top plan view, in section, of yet another embodiment of plunger means constructed in accordance with the concepts of the invention.
  • FIGS. 1, 2, 3, 4, 5, 6, and 7 there is shown an extrusion tool 20 including a plunger means 22 constructed in accordance with the concepts of the invention.
  • the plunger means 22 is affixed to a support 24 operatively coupled to a handle 26 pivotably mounted to a housing 28 having a nose portion 30 comprising an extrusion orifice arranged to selectively deform a connector advanced therethrough.
  • a return spring 32 provides a biasing force against the plunger support 24 to maintain the plunger means 22 in a retracted position prior to operation of the handle 26.
  • the plunger means 22 comprises a first plunger portion 34 having a first end 36 and a recessed portion 38 extending longitudinally rearwardly from the first end 36 and terminating in an upstanding surface 40. Extending rearwardly from the upstanding surface 40 is a chamber 42 providing a seat for one end of a biasing means such as a compression spring 44.
  • a second plunger portion 46 Slidably mounted on the first plunger portion 34 and moveable along the recessed portion 38 is a second plunger portion 46 having a first end 48 and a sec ond end 50.
  • a chamber 52 similar to chamber 42, extends forwardly from the second end 50 of the second plunger portion 46 towards its first end 48 to provide a seat for the other end of the compression spring 44.
  • the first plunger portion 34 is notched as at 54 to provide a bifurcated arrangement employable in a manner which will be described in greater detail hereafter.
  • the second plunger portion 46 is provided with a generally planar surface 56 slidable on a planar surface 58 defining the base of the recessed portion 38. As further illustrated in FIG.
  • first and second plunger means 34 and 46 respectively, have substantially rectangular cross sections of substantially equal transverse dimension. Accordingly, the sides of each of the first and second plunger portions may be closely confined within a suitable bore extending lengthwise of the housing 28 to provide at least a partial guide therefore.
  • a first plunger portion 60 may be provided with rib means 62 engaged within complementary slot means 64 in a second plunger portion 66 which, accordingly, is effectively guided by the ribs 62 between a first position wherein the first end 48 of the second plunger portion 46 is disposed generally forwardly of the first end 36 of the first plunger portion 34 (FIG.
  • first end 48 of the second plunger portion 46 is generally coincident with the first end 36 of the first plunger portion 34 (FIG. 5).
  • the first ends 36 and 48, respectively, of the first plunger portion 34 and the second plunger portion 46 each terminate in a generally planar end surface adapted to provide a generally uniform pressure against a connector such as 68 (See FIG. 2) positioned adjacent thereto for extrusion through a tapered orifice 70 extending axially through the nose portion 30 of the tool 20.
  • first and second plunger portions 34 and 46 may be modified, for example, by providing convex or concave side walls (not shown) slidable along complimentarily formed surfaces defining the inner walls of the housing 28 of tool 20, where necessary or desirable.
  • the side walls of each of the first and second plunger portions 34 and 46 adjacent their first ends 36 and 48 may be suitably tapered as shown at 72 and 74 in FIG. 6 to more closely follow the tapered contour of the adjacent sidewalls of the extrusion orifice 70.
  • the plunger means 22 is shown in its normally retracted position, which, incidentally, provides an unobstructed passageway from the opening 78 into the interior of the tool 20 adjacent the first and second plunger portions 34 and 46.
  • the plunger 22 is now advanced by movement of the handle 26 towards the housing 28 of the tool 20, causing a for- 1 ward displacement of the plunger means 22 to a position essentially as shown in FIG. 3.
  • the forwardly extending section of the second plunger portion 46 overlies the top surface 76 of the connector 68 during the forward motion of the plunger means 22.
  • the second plunger portion 46, the first plunger portion 34, and the connector 68 are advanced into the orifice 70, the second plunger portion 46 is maintained in its extended position by the compression spring 44 and continues to overlie theconnector 68 throughout the forward motion of the plunger means 22.
  • the connector 68 is subjected to opposing forces exerted by the selectively tapered sidewalls of the orifice 70 one of which is indicated at 78.
  • the surface 78 tends to urge the connector 68 towards the adjacent surface 56 of the second plunger portion 46 which prevents further transverse movement of the connector 68 so that as the first plunger portion 34 continues to advance the connector 68 through the orifice 70, the connector 68 is extruded through the exit end of the orifice 70 essentially as illustrated in FIG. 3.
  • the second plunger portion surface 56 thus serves to provide an auxiliary support surface for the connector 68 to insure that the connector is confined within the space available between the surface 56 of the second plunger portion 46 and the tapered sidewall 78 of the extruding orifice 70.
  • the second plunger portion 46 operates to selectively reduce the available opening to .insure proper extrusion of the connector 68 therethrough.
  • a pair of conductors 80 and 82 each having a bared end 84, 86, respectively, may be connected to one another. by the insertion of the bared ends 84 and 86 into a suitable conductor receiving orifice in the connector 68 prior to the extrusion of the connector 68 through the orifice 70.
  • the connector 82 has a transverse dimension d generally equal to the corresponding combined transverse dimensions of'both the first plunger portion 34 and the second plunger portion 46. Accordingly, as the plungerm eans 22 is advanced forwardly, the front end 48 of the second plunger portion 46 is caused to abut the adjacent surface of the connector 82 indicated generally at 83, whereby the second plunger portion 46 is longitudinally displaced rearwardly, compressing the biasing spring 44, and assuming a position relative to the front end 36 of the first plunger portion 34 essentially'as shown in FIG. 5. The first end 48 of the second plunger portion 46 and the first end 36 of the first plunger portion 34 thus present a generally contiguous surface bearing against the connector 82 during the extrusion operation.
  • the upstanding surface 40 disposed at the terminating end of the recessed portion 38 of the first plunger portion 34 is arranged to provide an abutment to restrict further rearward movement of the second plunger portion 46 during the extrusion operation.
  • the end surfaces of each of the first and second plunger portions 34 and 46, respectively, although shown and described hereinabove as generally planar may be suitably configured in a variety of other shapes which may include convex and concave portions arranged to cooperate with suitably formed complementary surfaces on connectors selectively designed for use in connection therewith. Additionally, various indicia may be provided as raised or recessed elements at the front surfaces of the first and second plunger portions to code or mark the connectors as they are urged through the restrictive nose orifice 70.
  • the second plunger portion 46 may be bifurcated in a manner similar to that illustrated with respect to the first plunger portion 34 to permit an increased taper to be employed in the nose portion orifice 70, where necessary or desirable.
  • the plunger means 84 comprises a first plunger portion 86 flanked by a pair of second plunger portions 88 and 90 respectively, each essentially duplicative of element 46 illustrated and described in detail hereinabove, and slidable along recessed portions 91 and 93 disposed on opposite sides of the first plunger portion 86.
  • the solid outline indicated by the reference numberal 96 defines the contour of the smallest of the three differently sized connectors which may be extruded through the nose portion orifice indicated as 98 in FIG. 9.
  • each of the second plunger portions 88 and 90 operate to reduce the transverse dimension of the orifice 98 while the first plunger portion 86 operates to extrude the connector 96 between the second plunger portions 88 and 90 and the tapered inner surfaces 110 and 112 of the orifice 98.
  • a second connector having a contour including the solid outline indicated by numeral 96 but further including a portion 100 indicated by the dotted outline adjacent the second plunger portion 88 may be extruded through the orifice 98 in a manner similar to that described with respect to the connector 82 shown in FIGS. 4 and 5.
  • the second plunger portion 90 provides the additional closure necessary to contain the connector including portions 96 and 100 properly within the orifice 98 for extrusion therethrough.
  • the embodiment illustrated in FIG. 9 functions in a manner similar to that described above with respect to the arrangement shown in FIGS.
  • both second plunger portions 88 and 90 are displaced longitudinally rearwardly to provide a generally contiguous surface comprising the front surfaces of both second plunger portions 88 and 90, and the first plunger portion 86. Accordingly, as the plunger means 84 is advanced forwardly towards the nose portion orifice 98, the front end surfaces of all three elements function cooperatively to urge the connector through the orifice 98. It will also be clear to those skilled in the art that each of the second plunger portions 88 and 90 may be cooperatively guided along the adjacent surfaces of the first plunger portion 86 by the employment of complementary ribs and slots such as the elements 62 and 64 illustrated in' FIG. 8.
  • a slot 108 bifurcates the first plunger portion 86 to pennit a variation in the transverse dimension thereof in a manner similar to that described above with respect to the element 34, whereby the second plunger portions 88 and 90 may more closely follow the inner tapered surfaces of the orifice 98, which are indicated generally at 110 and 112 in FIG. 9.
  • Plunger means for use in connection with an extrusion tool or the like comprising: a generally elongate first plunger portion having a first end and a recessed portion extending rearwardly from said plunger portion first end; a second plunger portion slidable generally longitudinally on said first plunger portion recessed portion and having a first end and a second end; and biasing means cooperative with said first plunger portion and said second plunger portion for biasing said second plunger portion first end selectively forward of said first plunger portion first end.
  • Plunger means as defined in claim 2 wherein said spring means comprises a compression spring and said second plunger portion has a longitudinally extending orifice, said compression spring being selectively engageable within said second plunger portion orifice.
  • Plunger means as defined in claim 1 further comprising means forguiding said second plunger portion along said first plunger portion recessed portion.
  • said biasing means comprises a compression spring
  • said first plunger portion has a longitudinally extending orifice communicating with said recessed portion, said compression spring being selectively engageable within said first plunger portion orifice.
  • Plunger means as defined in claim 1 wherein said first plunger portion first end terminates in a first generally planar surface, and said second plunger portion first end terminates in a second generally planar surface, said second plunger portion being movable rearwardly so that said second planar surface is generally coincident with said first planer surface to provide a generally contiguous surface thereat.
