Definitions

  • This invention relates to hand tools for crimping electrical connectors and particularly to a tool having means for feeding terminals or connectors in the form of a strip or belt to a position between the crimping dies.
  • An object of the invention is to provide an improved manually actuated hand tool having means for feeding connectors in strip or belt form to the crimping zone of the tool.
  • a more specific object is to provide a hand tool having a C-shaped head and having a strip or belt feeding means which permits feeding of terminals or connectors mounted on a relatively wide belt.
  • a further object is to provide a hand tool with belt feeding means in which the dies can not be moved relatively towards each other unless a connector is properly positioned between the dies.
  • a still further object is to provide a hand tool with belt feeding means having an improved method and means for guiding the belt away from the crimping zone after terminals or connectors have been removed therefrom.
  • a deflector surface which reverses the direction of travel of the belt after it leaves the dial mechanism and directs it away from the tool head.
  • the dial is indexed by means of a manually actuated lever disposed in close proximity to the tool handles in a manner such that both the actuating linkage for the dies and the actuating linkage for the indexing mechanism of the dial can be controlled with one hand.
  • FIGURE 2 is a view similar to FIGURE 1 but showing the indexing mechanism exploded from the body of the tool.
  • FIGURE 4 is a perspective view of a section of belting having electrical connectors secured thereto.
  • FIGURE 4 it is now known to the art to mount electrical connectors or terminals T on a belt in side-by-side parallel relationship by means of a strip S.
  • the belt has evenly spaced perforations P on the opposite side thereof from the connectors so that it the lines 7--7 of estates Patented ran. as, was
  • the present invention relates to an improved manually actuated hand tool for crimping connectors and having a means for feeding the belt to position the leading connector thereon between the crimping dies.
  • Lower extensions 20 of the guide plates are similarly slotted at 23 to permit their move ment past a pin 23 which also extends between the frame plates 2. This arrangement is such that the block 12 is, in fact, guided along its path of motion by the slots 22, 23 and the pins 24, 23.
  • a hand lever 31 for actuating the tool comprises a pair of plates 3i? secured in spaced apart side-by-side relationship by a block 26 and a fastener 32 which extends through each of the plates 3% and the block 26. Additionally, it will be seen from FIGURE 5 that the pin 24 extends through both of the plates 3% and the block to secure this block between the handle lever plates. The handle lever thus extends between the frame plates 2 and is pivoted to the frame plates for movement towards and away from the handle 1%.
  • Block 26- has a contoured cam surface 29 which engages a roller 3% mounted between ears 36 which extend from one link 33 of a toggle mechanism. This link 38 is pivotally mounted to the frame by means of pin 23 and is pivoted at it; to the other link of the toggle linkage.
  • Link 42 is in turn pivotally connected at 44 to block 12.
  • a spring 46 engages at one end a hook on the end or" link 38 and is anchored to a pin in the handle Ill at its opposite end so that the toggle mechanism is normally broken.
  • the dies are shown in the closed position although normally the handles will be spaced apart as in FIGURE 1 and the toggle will be broken.
  • the contoured cam surface engages roller 34 and straightens the toggle linkage to drive block 12 upwardly.
  • a ratchet device 48 in accordance with US. Patent 2,618,993 is provided to ensure complete closure of the handles and therefore complete crimping of an electrical terminal as explained in the cited patent.
  • a movable crimping die 54 is mounted on an L-shaped bracket 52 which is in turn secured to a plate 5i). This plate extends downwardly beside the block 12 and is secured or clamped thereto by means of a fastener as shown.
  • the movable die 54 does not rest directly on the upper surface of block 12 but rather upon the head 5d of a set screw so that the shut height of the tool can be adjusted merely by rotation of this set screw.
  • Plate 5d extends upwardly and into a slot or groove in a block 58 mounted between the upper arms 4 of the tool.
  • a tie plate 5'1 is secured to the front of block 58 and extends downwardly between the frame members 2. Beneath the lower surface of block 58 this tie plate Ell has an L-shaped bracket secured thereto which mounts the upper or fixed die es.
  • terminal or connector must be disposed with its axis extending transversely of the planes of the plates 2.
  • the mechanism for feeding connectors in belt form to position the leading connector on the belt between these dies will now be described.
  • the feeding mechanism is mounted in a bracket having a web 68 which extends parallel to the plates 2, a top flange 70 which extends inwardly towards the tool and over the block 58 and is clamped thereto by a fastener, and a lower inwardly directed flange 72.
  • the fiange 72 has a foot portion which bears against a plate 73 which, in turn, bears against the outside surface of the adjacent frame plate 2. 'The lower end of the bracket is held in position by fastener 23 which was previously identified as the lower pivotal axis as for the link 38.
  • the sprocket wheel 78 is rotatably mounted on a stationary stub shaft 76 secured in the web 68 of the bracket and has evenly spaced teeth 80 on its periphery for engagement with the perforations P of the belt. wheel has evenly spaced notches 82.
  • a traveler plate 84 is nested within the sprocket wheel and rotatably mounted on stub shaft 76.
  • This sprocket wheel has a chordal section 86 cut away on its face which is against Between the teeth the sprocket the sprocket and a pawl 88 is mounted in this cut-out section on a pivot pin 90.
  • the traveler wheel ' is oscillated by means of a lever 1&4 pivotally mounted on the pin 109 and having at its upper end, as viewed in FIGURE 6, a notch 106 into which extends the projecting end of the pin 90.
  • This lever is normally biased in a clockwise direction to the position of FIGURE 6 by means of a torsion spring 105 on pin 10% which reacts against a pin 107 on the surface of the lever.
  • the upperend of the lever has a circular recess 108 and a generally triangular projection 110 ad jacent thereto. This recess and projection cooperate with a pin 111 on L-shaped die holder 52 which pin extends rearwardly towards the traveler wheel and into the recess 168. This pin prevents movement of the lower die towards the fixed die if the indexing mechanism is not in the position of FIGURE 6 as is described below.
  • the surface reverses in direction and guides the belting along a generally U-shaped path which extends along the edge of the gap in the adjacent frame member as is shown in FTGURE 6 so that it leaves the indexing mechanism above sprocket wheel and generally parallel to the incoming belting.
  • a clamping member 118 mounted on a pin which extends through a sleeve 12% to a lever 122 pivoted at v1241p the web 68.
  • This, lever is normally biased in a manner such that the clamping member is urged against the surface of the sprocket wheel by means of a spring 126.
  • the indexing lever 104 When the indexing lever 104 is in its normal position, the block 12 and the movable die 54 can move upwardly but if, for any reason, the traveller wheel does not return to its initial. position, the pin 111 will engage the edge of the recess 108 and return the traveller wheel to its normal position. This pin also serves to prevent accidental rotation of the lever 104 and the sprocket wheel after the dies have started to move towards each other. The terminal between the dies can not, therefore, be moved-out of its proper position by accidental movement of the lever 104.
  • a hand tool for crimping electrical connectors onto the ends of wires comprising, a. C-shaped frame member having a fixed crimping die secured to one arm thereof and having a movable crimping die reciprocable towards and away from said fixed crimping die, means for feeding connectors in belt form to a position between said dies comprising a sprocket wheel mounted in a plane extending parallel to said frame member, means for indexing said sprocket thereby to feed said belt towards said frame member and position the leading connector thereon between said dies, and means for reversing the direction of travel of said belt after it passes said dies thereby to remove said belt from the crimping zone of said tool.
  • a hand tool for crimping electrical connectors onto the ends of wires comprising, a, C-shaped frame member having a fixed crimping die secured to one arm thereof and having a movable crimping die reciprocable towards and away from said fixed die, said dies being oriented to crimp an electrical connector having its axis extending normally of the plane of said frame member, means for feeding connectors in belt form to a position between said dies comprising, a sprocket wheel for engagement with said belt, said sprocket wheel being secured to said O- shaped frame member for rotation about an axis extending normally of the plane of said frame whereby, upon indexing of said sprocket said belt is fed between the arms of said C-shaped frame, member and the leading connector thereon is positioned between said dies, and a curved deflecting surface between said arms, said' deflecting surface being tangent tosaid sprocket wheel at one end and curving from its point of tangency in the direction opposite to the direction of
