Definitions

  • This invention relates to crimping tools, particularly of a type intended for use in crimping electrical connectors and terminals.
  • a crimped electrical connection in accordance with the present teachings of the art requires that the size of the wire and the size of the connector be correlated and a connector having the proper ferrule size must be used for each wire size. Furthermore, the ferrule must be crimped. with properly engineered tooling and the dimensions of the crimping dies must be correlated with the size of the ferrule which is being crimped. Good quality crimped connections cannot, then, be made carelessly but must be formed by. the use of ferrules and crimping dies which are judiciously selected with reference to the size of the wires involved.
  • An object ofthe present invention isto provide a crimping tool capable of crimping terminalsof widely varying sizes thereby to permit its use in making crimped connections with wires of varying sizes.”
  • a further object is to provide a unitary and self-contained device which can be rapidly adjusted fora given ferrule size without the removal or the replacement of dies or other interchangeable parts.
  • a more specific object is 'to provide a pair of die plates. each-having: multiple pairs of die surfaces arranged such that one pair of die surfaces of one of the plates is cooperable with more than one pair of die surfaces on the other of the plates.
  • FIGS. 1 and 2 are plan views of a pair of die plates in accordance with theinvention
  • Figures 3, 4, 5, and 6 illustrate the various cooperative relationships of the die plates of Figures 1 and 2 for crimping ferrules of varying sizes
  • FIG.7 is a fragmentary perspective view of a tool in accordance with the invention.
  • Fig. 8 is a perspective view of a crimped connection between a terminal and a wire formed by the die set of the instant invention
  • Figure 9 illustrates the crimping of an alternative type of terminal
  • Figures 10 and 11 show an alternative form of the invention
  • e Figure 12 shows a further alternative form of the invention.
  • I provide a pair of die plates 2, 4 which are mounted for rotation on stub shafts 6,'8 and which provide openings as shown at 10 and 12 to facilitate locking the plates in a given position relative to these stub shafts.
  • Plate 2 has edges 14 which would intersect, if projected to their points of intersection, to define a square.
  • Die stations indicated by A, B, C, D, E and F are located around the sides of plate ,2 and impart to the plate the appearance of an irregular polygon having reentrant surfaces at spaced locations along its edges.
  • die surfaces 16a, 16b extend inwardly of their respective sides 14 and intersect these sides at an angle of These die surfaces are further characterized in that they are of substantially the same length and intersect each other at an angle of 90. It will be apparent from the drawing that these relationships are achieved by virtue of the fact that each of the surfaces 16a, 16b intersects its respective side 14 of plate 2 at points which are equidistant from the intersection of the projections of the same two of the sides 14. In other words, these die surfaces define two sides of a square, the other two sides of which wouldbe defined by the projections of the adjacent sides 14 of the die plate itself.
  • two similar die surfaces 22a, 22b extend inwardly from adjacent sides of the plate and these surfaces have the same relationship to each other and to their respectivesides of the plate 2 as do the surfaces 16a, 16b, although, as is apparent from the drawing, the surfaces 22a, 2% are somewhat shorter than the: surfaces 16a, 16b;
  • Stations B and C are located adjacent to each other at one of the remaining apices of plate 2 and provide die surfaces 18a, 18b and 2012,2011 respectively.
  • Surfaces 18a and 20b extend at right angles to the adjacent one of the sides 14 while surfaces 18b; 20a extend substantially normally of each other and are separated by a surface 11.
  • the remaining die surfaces at E and F, 24a, 24b, 26a, 26b are somewhat similar to the die surfaces at B and C, although these surfaces at E and F have dimensions which are different from the dimensions of the die surfaces at Band C and are separated by a notch 25 rather than a fiat surface.
  • Plate 4 provides sides 28 which, like, plate 2, formthe sides of a square and die surfaces are provided atstations G, H, I, J, and Kat spaced locations around these sides.
  • die surfaces 30a,f30b, 3201, 32b, ,and34a, 341) are provided all of which are substantially similar to die surfaces at A and D of plate 2. It should be notedthat the surfaces 32a, 32b at station G are of substantially the same length as the surfaces 16a, 16b of station A while the surfaces at H and: K are of intermediate lengths, smaller than the surfaces 32a, 32b and larger than the surfaces 2251,2212. Stations I and I provide surfaces 36a, 36b and 38a, 38bwhich are substantially similar to the surfaces at stationsB and C.
  • the die-plates may be mounted on anysuitable tool or press in such manner that they can be moved toward or away from each other as described below, and Figure 3 shows the die plates in their meeting relationship when the tool is closed to bring the die enter between the surfaces 32 on plate 4. Additional sizes offerrules can be crimped if the die surfaces H or K of 'plate 4 are brought into engagement with surface A. in plate 2, of these latter combinations not being specifically illustrated in view of the fact that the principle of the nesting and meeting die surfaces is illustrated in Figures 3 and 4.
  • FIG 5 it can be seen that surfaces F, E of plate 2 can be brought into engagement with the die surfaces at I, J of'plate 4 for crimping ferrules of somewhat smaller sizes than can be accommodated by any combination of the surfaces A, D, K, G and H.
  • the F--I combination is adapted to crimp a relatively large ferrule than the EJ combination when the dies are in the orientation of Figure 5.
  • Figure 6 shows the arrangement when die surfaces at C and B on plate 2 are brought into engagement with the surfaces at I and I on plate 4. This arrangement accommodates additional smaller sizes of ferrules than can be crimped with the larger die sizes.
  • FIG. 7 and advantageous tool for the die set previously described is shown to comprise a pair of handles 54 which are pivoted together at their ends 56 for movement towards and .away from each other, such movement being limited by the provision of stop means shown at 55.
  • Adjustable shoes or carriers 58 are pivoted as at 57 to the handles adjacent the ends and levers 40 are in turn pivoted at 64 to these their upper ends and are connected together by means .of v a link 50 and pins 52.
  • Die-plates 2, 4 are mounted on the levers between the ends of extension plates 42 by the previously described pins 6, 8.
  • washers or the like 48 are affixed as by upsetting the ends of pins 6 and 8.
  • Removable locking pins 46 extend through each of the plates 42 and are such diameter as to extend through the openings 10, 12 in plates 2, 4 to lock the die plates in a given position relative to the plates 42.
  • the desired combination of die surfaces on the plates 2, 4 is selected and the plates are rotated so that the desired surfaces are in opposed relationship to each other.
  • the plates are then locked in position by means of the pins 46 and the handles are moved relatively away from each other to position plates. 2, 4 in spaced-apart relationship.
  • the stripped end' 66 of the conductor 68 is inserted into the ferrule 70 of a connector such as the connector shown in Figure 8 having a ring tongue 72 on its end.
  • the connector is then positioned between die plates 2, 4 and the handles 54 are moved relatively towards each other to crimp the ferrule onto the stripped end of the conductor.
  • a crimp having a square cross section is produced as shown in 74 in Figure 8. Regardless of the size of the ferrule crimped, a'crimp having a square cross section is produced although, as well be explained below, with alternative embodiments the cross section of the crimp can depart from that of the square.
  • surfaces H and K can nest with the surface D to accommodate additional size ranges.
  • Crimping tools in accordance with the invention are "adapted to the crimping of flag type terminals as .well
  • a flag type terminal having a ferrule 73 and a laterally extending flag portion 75 can be positioned between the appropriate dies of plates 2, 4 such that the surface of the flag portion extends along one of the edgesof one of the dies.
  • the ferrule can be crimped notwithstanding the fact that flag portion 75 prevents complete closure of the dies by virtue of the resilience of the tool.
  • ure 12 shows a further modification in which the die plates take the form of regular pentagons and the die surfaces 84 and 86 extend inwardly from the apices at angles equal to the angles between the adjacent sides. Again, any one of the die surface pairs of one of the plates 82 will mate or nest with more than one pair of die surfaces on plate 84.
  • Figures -12 illustrate that the principle of the invention is applicable to any regular polygon and that to achieve the objects of this invention, the several die surfaces of each polygon must extend inwardly at the same angle with respect to the adjacent polygon side as the angle between intersecting Sides of the polygon.
  • a tool for crimping electrical connectors of varying sizes comprising a pair of die plates each having portions of sides of a regular polygon and providing a plurality of pairs of reentrant die surfaces at apices of said polygon, each die surface intersecting a side of said polygon at an angle equal to the angle of the polygon whereby a pair of die surfaces of one of said die plates will mate with more than one pair of die surfaces of the other one of said plates, and means for moving said die plates towards and away from each other.
  • a tool for crimping electrical connectors of varying sizes comprising a pair of die plates each having portions of sides of a regular polygon and providing a plurality of pairs of reentrant die surfaces at apices of said polygons, each die surface of each pair extending inwardly of its side at the same distance from the included apex as the other die surface of the same pair, and different pairs of die surfaces extending inwardly at varying distances from their respective apices whereby, one pair of die surfaces of one of said die plates will mate with a plurality of pairs of die surfaces of the other of said plates.
  • a tool for crimping electrical connectors of varying sizes comprising a pair of co-planar die plates and means for moving said die plates towards and away from each other, said die plates having sides forming portions of similar regular polygons, each of said die plates providing on at least some of its apices a pair of reentrant die surfaces, each die surface of each pair being spaced from the included apex by substantially the same distance as the other die surface of the same pair, dliiferent pairs of die surfaces being spaced different distances from their respective apices, and each die surface intersecting its adjacent side at an angle substantially equal to the included angle between adjacent sides of said die plates, whereby a pair of die surfaces of one of said die plates will mate with any pair of die surfaces of the other of said die plates.
  • said means for moving said die plates towards and away from each other comprises a pair of levers each having a handle connected thereto, whereby upon movement of said han- .dles said levers are moved towards and away from each other, each of said die plates being rotatably and lockably mounted in one of said levers whereby a selected pair of die surfaces of one of said die plates can be brought into engagement with a selected pair of die surfaces of the other of said plates.
