Definitions

  • a crimping tool having link members pivotally connecting jaw members and handle members together.
  • the jaw members carry crimping die members which are moved toward each other upon operation of the handle members to crimp a connector member onto a cable member.
  • Guide means is provided to move the crimping die members along a straight-line path.
  • Adjustment means are provided in opposing surfaces of the handle members on each side of the pivot point connecting the link members to the handle members for adjusting the crimping die members relative to each other.
  • the crimping die members have multiple crimping stations and locking pin assembly means locks the the die members in one of the multiple crimping stations. Locator means are provided on the locking pin assembly means adjacent the crimping die means for locating a connector member between the crimping die members.
  • Crimping tools which are hand-operated may be basically divided into tools in which the crimping dies describe an arc during the crimping operation and tools in which the crimping dies are moved towards one another in a straight line path in order to effect crimping.
  • the instant invention is directed toward the latter type tool.
  • Another object of the present invention is to provide a crimping tool which produces a more uniform deformation of the wire strands being crimped.
  • a further object of the present invention is to provide a crimping tool which has self-contained, but replaceable multi-position, multi-purpose crimping, wirecutting and stripping features.
  • An additional object of the present invention is the provision for a crimping tool which uses many identical parts in assembly. 7
  • a still further additional object is the provision for a hand-crimping tool which has a unique adjustment feature to compensate for crimping dies and related parts wear.
  • FIGURE 1 is a front elevational view of a preferred embodiment of a tool in accordance with the invention.
  • FIGURE 2 is an exploded View showing the various parts of the tool head
  • FIGURE 3 is a perspective exploded view illustrating the adjustment feature
  • FIGURE 4 is a partial cross-sectional view of the adjustment feature
  • FIGURE 5 is a front elevational view of the tool showing the adjustment feature
  • FIGURE 6 is a cross-sectional view of a die locking pin locked between plates
  • FIGURE 7 is a view similar to FIGURE 6 but showing the die locking pin in its partial withdrawn position to permit rotation of the die;
  • FIGURE 8 is also a view similar to FIGURE 6 but showing the die locking pin in its completely withdrawn position to allow removal of the die;
  • FIGURE 9 is a perspective view of the locking pin.
  • FIGURE 10 is a perspective view of a completed termination made in accordance with the invention.
  • the reference numerals 2 and 4 denote a pair of lever jaw plates pivotally connected one to another by means of tie plates 6 and affixed to corresponding lever jaw plates by use of tie bolts 8 and 10.
  • Lever jaw plates 2 and 4 are pivotally connected by connecting bolts 12 and 14 at their respective base portions to one end of links 16 and 18 which are also pivotally connected by bolts 20 and 22 or the like within slots 13 of handle assemblies 15 and 17.
  • the two handle assemblies 15 and 17 are centrally connected one to the other by pivot means designated as 24.
  • Handles 26 and 28 with grips attached are provided on the handle assemblies.
  • Each carrier plate contains a channel 33.
  • the channels in each set of carrier plates are in opposed relationship and define cooperating die guide means for guide plate 34.
  • the guide plate has affixed at its centermost portion an axially aligned pin 36 which prevents the guide plate from being accidentally removed from the guide means when in use.
  • Each carrier plate has an arcu- I ate recess 35, and pin 36 is disposed within these opposed recesses when the carrier plates of one set move toward the carrier plates of the other set.
  • Rotatable multi-position crimping dies 38 and 40 similar to those disclosed in U.S. Patent No. 2,900,854, which is assigned to the present assignee are located between pairs of lever jaw plates and are rotatably contained by means of die center pins 42 located on frames 45 of locking pin assemblies 46.
  • the dies are prevented from rotating by means of die indexing pins 44 which engage corresponding equally-spaced or positioned holes 47 in the dies, see FIGURE 2, which are also located on frames 45 of locking pin assemblies 46.
  • Additional die indexing pins can be provided in diametrical relationship on the frame 45 for engagement with corresponding holes on the dies so as to more effectively lock or retain the die in position.
  • Pins 42 are similar to those described in U.S. Patent No. 3,080,184, and which is assigned to the present assignee. The detailed procedure for rotating the dies will be described hereafter.
  • the tool handles 26 and 28 are manually opened far enough so that the connector with conductor to be crimped can easily be positioned between the dies.
  • the first crimp or compressing operation takes place at one end of the connector and the second and each subsequent crimp is formed inwardly toward the center of the conductor.
  • the other end of the connector is crimped in the same manner.
  • the view of the completed crimp can be seen in FIGURE 10.
  • Most prior art lever type tools tend to crimp so as to result in a bent or twisted connection. That is, the crimp indentations are in twisted relationship one to another due to the arcing lever action of the crimping dies rnOving against the connector body.
  • the present invention achieves a uniform deformation of the connector body because the crimping dies are in one plane or straight acting.
  • the present invention also provides, due to the straight line die movement, a more uniform crimping of the wire strands when compared to prior art connecting tools.
  • each die has several crimping die stations and a wire-cutting surface. It is also possible for each die to be provided with multiple crimping die stations, as well as wire-cutting and wire-stripping means. It is also possible to replace the dies with those of another size or sizes so that a wide range of connectors can be crimped in the tool.
  • Adjustment for die surface, guide plate, or pivot point wear is compensated for and corrected by means of adjustment and lock screws 48 and 50 (see FIGURES 3-5) which are located on the inner area of the handle assemblies 15 and 17.
  • handles 26 and 28 see FIGURE 5
  • a connector locator and wire stop means 6% is provided as an integral part of frame 45 and is located at the extreme end away from die indexing pin 44 (see FIG- URES 1 2 and 9 ).
  • the above-described means axially locates the connector body to be crimped in proper alignment for crimping as well as properly positions conductor wire strands between the cutting surfaces of the dies.
  • the connector locator and wire stop means also prevents the wire strands from becoming accidentally pinched between parts of the tool head. It is also conceivable that the means described could be an integral part of the lever jaw plates or tie plates.
  • the tool is designed so that numerous identical parts are used, for example, the dies, tie plates, handle assemblies, locking pin assemblies, jaw plates, links and adjustment and lock screws are all identical to their respective counterparts.
  • the handles are preferably of Fiberglas so as to reduce the weight of the tool in order that it can be easily handled while in operation. All parts used in the manufacture of the tool are economically and easily produced.
  • the tool converts and provides double lever handle action into straight path movement at the crimping dies; more uniform deformation of the wire strands when crimped due to the straight action; self-contained but replaceable multi-position, multi-purpose crimping, cutting and stripping means; a tool which uses many identical parts and unique adjustment means to compensate for parts wear.
