Definitions

  • a hand tool such as a wrench
  • a hand tool is not required to have a high degree of precision and exactness as regards the movement of the jaws towards and away from each other and as regards deflection (i.e. elastic deformation) of the tool during use.
  • deflection i.e. elastic deformation
  • the jaws of the wrench need not be precisely aligned with each other and the deflection of the tool jaws is of no importance so long as the tool is capable of gripping the part being worked upon.
  • hand tools are use for critical operations such as the crimping of electrical connectors and terminals.
  • the crimping dies are designed with the intention that they will move along a substantially perfectly straight line path towards each other when they crimp a connector. If the dies move obliquely towards each other, inferior results are obtained even if the departure from rectilinear movement is slight. it follows that hand tools for such operations should be capable of moving the dies together along a substantially straight line path in a precise and exacting manner.
  • Tools of this type usually have a fixed die mounted on one of the arms of the C and the other die mounted on a ram which is reciprocable in the other arm and across the gap of the frame.
  • the fixed die is rigidly mounted on the one arm, it has been found that this arm will deflect under normal crimping forces and such deflection misaligns the dies with respect to each other.
  • the crimping forces in the dies and applied to the connector become unbalanced and are partially wasted in that they by-pass the connector and are expended in stressing and deflecting the tool frame.
  • An object of the present invention is to provide an use.
  • a still further object is to provide a C-frame type hand tool for crimping electrical connectors and having improved crimping, die holding and aligning means which is substantially independent of the tool frame.
  • a further object is to provide a C-frame type tool of improved efflciency.
  • a preferred embodiment of the invention comprising a pair of generally C-shaped frame members having handle extensions on one end thereof.
  • the C-shaped frame members are secured together in spaced apart side-by-side relationship by suitable fasteners and spacers.
  • a block is mounted between corresponding arms of the frame members for pivotal motion about an axis extending normally of the plane of the frame members and a fixed crimping die is mounted on this block.
  • a movable die is mounted on a die guide plate which slidably engages a guideway integral with the fixed die in order to guide the movable die rectilinearly towards and away from the fixed die.
  • the movable die is reciprocated by means of a block which is contained between the frame members and guided for rectilinear motion by means of guide plates which cooperate with the spacers which secure the frame members together in spaced apart relationship.
  • Amovable handle or lever is pivotally mounted to the frame of the tool and a suitable linkage is provided to move the movable block towards and away from the fixed block.
  • the salient feature of the invention is that the C-shaped frame is primarily a load carrying device and it is not relied upon entirely for precise location and guidance of the crimping dies, the dies being located in the frame and guided by the guide plates.
  • This feature of the invention permits the use of a relatively light-weight frame and avoids the need for machining guideways in the frame for the movable die.
  • the frame can be made of relatively thin stampings rather than a heavy forging.
  • FIGURE 1 is a perspective view of a tool in accordance with the invention.
  • FIGURE 2 is a perspective View illustrating the die guiding and aligning mechanism of the embodiment of FIGURE 1.
  • FIGURE 3 is a side view with parts broken away of the embodiment of FIGURE 1.
  • FIGURES 4, 5, and 6 are views taken along the lines 4-4, S-5, and 6-6 of FIGURE 3.
  • FIGURE 7 is a side view illustrating the manner in which deflection of the tool frame is compensated for during use.
  • FIGURE 8 is a fragmentary frontal view illustrating the manner in which tools in accordance with the invention permit the use of slightly warped frame plates
  • the disclosed embodiment of the tool comprises a pair of frame plates 2 having C-shaped head portions with upper arms 4 and lower arms 6. Handle extensions 8 project from the lower arms 6 and a hand grip 10 is advantageously fitted over the ends of these extensions.
  • a block 12 is mounted between the upper arms 41 by means of a fastener M which extends through the plates 2 and through an opening in the block. For reasons which will be apparent as the description proceeds, block 12 should be capable of pivotal motion about the axis of fastener M.
  • a strap or plate 26 is secured to the surface of block 12 between the frame plates 2 and extends downwardly towards the gap of the tool head.
  • this strap has an L-shaped bracket 28 secured thereto by means of a rivet 27 and a pair of upper or fixed crimping dies 3t 31 are secured to this bracket by a screw 35, one of these dies being provided to crimp the wire barrel portion of the connector while the other die is provided to crimp the insulation support portion of the connector.
  • a reciprocable block 32 is contained between the lower arms 4 of frame plates 2 and has a guide plate 34 on each side thereof secured to the block by means of a roll pin 33 and a pin 56.
  • These guide plates each extend downwardly toward the handle extensions 8 and have slots 36 in their lower ends to permit their movement past a pin or rivet 18 which extends between the plates.
  • the guide plates also have upper extensions which project inwardly towards the web of the tool head and these upper extensions are slotted at 4t) to permit movement of the plates past a pin or rivet 16 which also extends between the frame plates.
  • the reciprocable block 32 is, thus, guided by means of the pins 16, 18 and the slots 36, 40 in the guide plates.
  • Teflon (polytetrafluorethylene) washers 39 are provided on pins 16 and 18 between the surfaces of the guide plates 34 and the frame plates 2. These Washers constitute a bearing surface over which the guide plates move, Teflon being a preferred material for these washers because of its self lubricating property.
  • a .die guide member and die mounting plate 42 is contained between the frame plates 2 and clamped to the rear surface of the block 32 by means of a machine screw 46 and a slot 44 in the lower end of the die mounting plate, slot 44 being somewhat wider than the diameter of the screw to permit both axial and lateral adjustment for reasons explained below.
  • An L-shaped bracket 43 similar to the bracket 28, is riveted to plate 42 at a location above the surface of block 32 and movable dies 41, 43 are mounted in this L-shaped bracket.
  • the crimping dies shown are of the type which have bearing surfaces, as shown at 45, on each side of the surfaces which support and crimp the connector. In the case of dies of this type, these bearing surfaces should be parallel to and against each other when the dies reach their fully closed position as shown in FIGURE 3.
  • a screw 50 threaded into the upper surface of the block 32 has an enlarged head which supports the lower dies and transmits thrust thereto from the block 32. Screw is locked in position by a recessed head set screw 51 disposed in the tapped hole which receives screw 46.
  • the screw 50 provides a convenient means of adjusting the tool to compensate for manufacturing variations in the sizes of the parts of the linkage and blocks 12, 32 as is discussed below.
  • the upper end of the plate 42 extends through a recess 29 in bracket 28 and is slotted at 54- to permit movement past the rivet 27 by means of which bracket 28 is secured to strap 26. This arrangement maintains the two dies in proper orientation with respect to each other and prevents lateral movement of either die out of the plane of the frame plates.
  • the rear face of block 12 has a recess for reception of the end 52 of the die guide plate, this recess being somewhat oversized with respect to the end of the die guide plate.
  • any suitable type of linkage may be provided to reciprocate the block 32.
  • the lower end of this block is slotted and pivotally connected at 56 to one link 58 of a toggle.
  • Link 58 is pivoted at 5? to the other link 69 of the toggle mechanism which in turn is pivoted on a fixed axis at 18.
  • Link 60 of the toggle has cars 62 extending on each side of the link 58 and a cam follower or roller 64 is rotatably mounted between the ends of these ears.
  • This cam follower is en gaged by a contoured cam surface 66 of a block 68 which is mounted between a pair of handle levers 70 pivoted at their inner ends between the frame members 2 on pin 16.
  • the lower ends of the lever formed by the plates 70 is advantageously provided with a hand grip '76 similar to the grip In) and these lower ends are maintained in proper spaced apart relationship by rivets 72, 74 having cylindrical spacers in surrounding relationship thereto.
  • This type of linkage is more fully disclosed and is claimed in U.S. Patent No. 3,029,670.
  • a ratchet type device 78 is provided between the handles of the tool in order to ensure complete closure of the dies as is explained in U.S. Patent 2,618,993.
  • an electrical connector is placed between the crimping dies and the handle 76 is moved relatively towards the handle lit) to straighten the toggle linkage and drive the block 32 and with it the movable die towards the fixed die.
  • the toggle linkage is normally maintained in broken condition by a spring 61 connected at one end to a hook on link 6t and at its opposite end to a previously mentioned pin or rivet 20.
  • the arms of the frame (arms 4 and 6 of the disclosed embodiment) will deflect and move apart when the frame is stressed during use. If the fixed die is rigidly mounted in one of the arms and is in substantially perfect alignment with the movable die when the frame is not stressed, then the fixed die will be carried out of alignment when the frame is stressed. This effect can be highly detrimental in the case of electrical connector crimping dies designed to mate in substantially perfect alignment with each other.
  • FIGURE 7 illustrates the deflection of the upper arms 4 when the dies are closed, the amount of deflection being highly exaggerated for purposes of illustration.
  • the upper arms 4 are not visibly deflected. It can be seen that deflection of the upper arm 4 does not result in misalignment of the dies for the reason that when the bearing surfaces of the dies come together, the upper block 12 will pivot about its axis 14 as deflection proceeds and alignment will be maintained. Pivoting of block 12 is,
  • stampings rather than forgings although this feature can be incorporated into a tool having a forged or other unitary frame.
  • FIGURE 8 is a highly exaggerated frontal view showing a tool having its two frame plates 2 warped in the same direction so that they are substantially parallel to each other and have an arcuate profile. The dies are not shown in this view for reasons of clarity and because of the high degree of exaggeration of the warpage.
  • the crimping dies will move along a straight line towards and away from each other in spite of tool frame warpage for the following reasons.
  • the lower (movable) dies are secured to the guide 42 by means of the L-shaped bracket 43 which is riveted to the guide.
  • the upper end 52 of this guide plate is slidably received in the recess 29 which is only slightly wider than the guide plate itself so that the guide plate and the lower dies. are restricted to movement along a straight line path towards the fixed dies, this straight line path constituting a chord with respect to the curvature of frame plates 2.
  • the reciprocable block 32 Since the reciprocable block 32 is relatively remote from the block 12, it can not be aligned with the block 12 and the guide plate 42 because of the curvature of frame plates 2.
  • the slot 44 in the lower end of guide plate 42 is wider than the diameter of screw 46 so that under the conditions of FIGURE 8, this screw is disposed on the lefthand side of the slot.
  • the center line of the guide plate and the center line of block 32 extend angularly of each other, a condition which is brought about by the curvature of frame plates 2.
  • the surface of set screw extends angularly of the underside of the lower die so that when the handle 76 is moved towards the handle ill, the lefthand side only of this set screw will initially transmit force to the lower die.
  • the block 32 is realigned with respect to the underside of the lower dies until the center line of block 32 is almost parallel to, but offset from, the center line of the guide plate.
  • the guide plates 34- are similarly cocked or aligned since these members are secured to the block by the pin 33.
  • the block 32 is realigned until its center line is almost parallel to, but offset from, the center line of the guide plate. Perfect parallelism of these two center lines is not necessarily achieved for the reason that some deflection (elastic deformation) of block 992, of set screw 5d, of the die guide plate 4-2 and other associated parts will take place and these deflections will contribute to the bringing of the two dies into alignment with each other. This deflection takes place for the reason that the parts are not axially and symmetrically stressed when the dies are moved relatively towards each other but tend to be stressed more on one side than on the other; for example, the set screw will be compressively stressed on its lefthand side as viewed in FIGURE 8 to a greater extent than on its right side. While deflection of these parts to some extent is inevitable and, in fact, beneficial, the realignment of the parts as previously explained is of greater importance in achieving alignment of the dies than is the deflection effect.
  • FIGURE 8 assumes the Worst possiblecondition of warpage of the frame plates 2. If these frame plates are warped in opposite directions, i.e. if each plate is warped inwardly or outwardly during manufacture, they will be brought into substantial parallelism when they are secured together by the fasteners 16, 18 and spacers 21, 25 and by the block 12 which functions as a spacer. Under ideal conditions of manufacture, the frame plates will not be warped at all but such ideal conditions will not always obtain in stamping operations or other forming operations where thin plate-like members are being formed and manu facturing tolerances must, as a practical matter, be allowed. It is emphasized that FIGURE 8 is a highly exaggerated view. Where warpage is present in the frame plates 2, it will be very slight and would not be visible to the unaided eye.
  • screw 50 is provided for the purpose of adjusting the tool to achieve substantially perfect bottoming of the dies and optimum utilization of the toggle mechanism.
  • the links 58, 6% should be in a straight line with respect to each other at the end of the stroke. To achieve this result, the bottoming surfaces of the dies should be against each other when the links are in alignment and the handles are fully closed. Because of manufacturing variations in the links and blocks 12, 32 and because of the deflection of the upper arms 4 of the frame members when the tool is used, perfect bottoming usually can not be achieved without adjustment of each individual tool.
  • the screw 59 is adjusted until the required spacing between the head of the screw and the underside of block 12 is obtained when the handles are closed, the links: are in alignment,
  • a C-head tool in accordance with the invention has :a higher efliciency than a rigid frame C-head tool or" the conventional type where both tools have the same type of actuating linkage and other factors are the same.
  • efiiciency refers to the handle pressure required by the tool operator to achieve a given compressive force onthe terminal being crimped, a low handle pressure being a desideratum.
  • the reason for this advantageof the invention is that since the dies are substantially perfectly aligned with each other when they are closed, virtually all of the force applied to the dies is transmitted uniformly through the dies and the connector being crimpec.
  • the precision of closure of the crimping dies is thus controlled by the elements shown in FIGURE 2, namely blocks 12, 32, by the straps and plates 26, 42, by the die holders 28, 48, and by the set screw 50.
  • the path of reciprocation of the movable block 32 is determined entirely by the pins 1%, 16 and by the slots 36, 40 in the guide plates.
  • the precision of operation of the tool does not then depend upon the frame itself but by the pins 16, T18 and their location with reference to the pin M. Because of this arrangement, considerable manufacturing variations can be tolerated in the frame parts or in the linkage without sacrifice of precision in the operation of the tool.
  • the guide pins 16, 13 are relatively widely spaced apart and are remote from block 32. This arrangement minimizes arcuate movement of block 32 due to the clearances between the pins 16, 18 and the slots 40, 36. Since the plates move relatively past the pins, there must be a slight clearance between these parts. This clearance, however slight, permits arcuate motion of plates 34 and block 32 about either of the pins as a center. For a given clearance between the pins and slots, the amount of arcuate movement is reduced as the spacing between the pins is increased. It follows that wide spacing between the pins as in the disclosed embodiment is desirable.
  • the pivoted upper die arrangement can be used in a tool having a solid forged or machined frame and having a conventional ram which is movable in a guideway in the frame as disclosed in US. Patent No. 3,029,670.
  • a tool of this type would have the advantage of self alignment of the upper die in the event of deflection of the C-frame but would otherwise be conventional.
  • the disclosed arrangement of using the slotted guide plates 34 and the pins 16, 18 to guide the movable die can be employed without necessarily having a pivoted upper die.
