  • Figure 2 is a cut away view of the tool shown in Figure 1, with the jaws in an open position and the ram retracted;
  • Figure 3 shows a sectional view taken through plane 33 of Figure 1 but with the jaws in closed position
  • Figure 4 is a perspective view of a block forming part of a tool comprising another embodiment of the invention.
  • Figure 5 is an exploded view of the embodiment partially depicted in Figure 4.
  • Figure 6 is a plan view of the embodiment shown in Figures 4 and 5;
  • Figure 7 is a sectional view taken through plane 7-7 of Figure 6.
  • the tool shown in Figure 1 employing principles of this invention consists of a body member, for example a block 10, made in two sections for ease of assembly.
  • a body member for example a block 10, made in two sections for ease of assembly.
  • a pair of jaws 12, 14 which are pivoted to the block at 18, 20.
  • the inner wall of the block is tapered at 22 ( Figure 3) to permit the jaws to pivot between open and closed positions.
  • One end of each jaw has a pivot pin 24, 24 secured to a link 26, 26' respectively. These links are secured together by a common travelling pivot 28.
  • a handle 30 is secured to link 26 to facilitate operation of the jaws. Rotation of the handle 30 operates the linkage to open and close the jaws. Openings 31, 31' in the block accommodate handle 30.
  • Each jaw contains a complementary segment 32, 34 of a die nest.
  • a pair of pins 36, 38 secure links 40, 42 to the block.
  • the opposite ends of these links are pivoted at 44, 46 to a pair of handles 50, 48, respectively which in turn are pivoted to each other and also a ram 52 through a common pivot pin 54.
  • the ram is longitudinally movable by the operation cf the handles.
  • One end of the ram constitutes a die 56 which cooperates with a recessed rates atent 0 portion 58 in the die nest to deform a work piece.
  • opening 60 in the ram accommodates a portion of the conductor when it is desired to secure a connector to an intermediate portion of the cable.
  • Crimping the connector to'the cable is accomplished I by stripping the cable and adjusting the connector thereon in the manner shown and described in my copending application identified above. With jaws 12, 14 in the open position and ram 52 retracted (as shown in Figure 2) the conductor and cable are inserted within the jaws. ,Handle is moved in a clockwise direction to effect the closing of jaws 12, 14 through linkage 26, etc. The jaws pivot about pins 18 and 20. Closing of the jaws radially deforms the connector onto the cable. After the jaws are closed, handles 48, 50 are brought together to cause ram 52 to move longitudinally toward the die nest. The die surface 56 of ram 52 cooperates with the recessed portion 58 of the die nest to deform the connector longitudinally. An opening 60 in the ram permits the cable to pass through the ram so that the connector may be secured to the cable at a point intermediate of the ends.
  • Figure 4 is a perspective view of a jaw 70 containing a die.nest 72.
  • a second jaw 74 ( Figure 5) contains a complementary die nest 76. Jaw 74 is pivoted to jaw 70 by means of a pivot pin 78.
  • a longitudinal ram fits into an opening 82 in jaw 70.
  • One end of the ram forms a die 83 which cooperates with a counter-bored section 84 of the die nest (see Figure 7).
  • Ram 80 also has an outer threaded portion 86 which cooperates with the threads 88 on the inner surface of opening.
  • ram 80 has wrench flats 90 to accommodate a standard wrench W as shown in Figure 6.
  • An opening 60 in the ram accommodates the bare end of the cable.
  • the connector and cable are extracted from the tool by reversal of the operation.
  • a tool is provided which radially and longitudinally deforms a connector onto a conductor by use of standard, hand operated tools.
  • a tool for crimping an electrical connector onto a conductor including: a block, die nests in the block for receiving an electrical connector, the die nests being relatively pivotal between an open position for renests between the open and closed positions including a pair of links each pivoted at one end to one of the die nests, and a travelling pivot securing the other ends of each link together, a longitudinally movable ram for deforming the connector means cooperating with the ram to deform the work piece, and a pair of handles pivoted between the ram and the block for effecting longitudinal movement of the ram upon operation of the handles.
  • a tool for deforming an electrical connector onto a conductor including: a block, a pair of complementary jaws forming a die nest pivoted to and within the block, linkage means secured to a first handle and to the jaws for opening and closing the dies upon actuation of the handle, a pair of gripping handles pivoted to the block, and a ram longitudinally movable in the block and pivoted to the gripping handles so that actuation of the gripping handles causes the ram to move longitudinally with respect to the die nest, and means cooperating with the ram to deform the work piece whereby a connector may be inserted in the tool and the first handle operated to actuate the jaws causing the die nests to deform the connector and the gripping handles subsequently actuated to cause the longitudinal ram to deform the connector.
  • a tool for deforming an electrical connector onto a conductor including: a body member, a plurality of jaws forming die members, said jaws pivoted to and within the body member, linkage means secured to the jaws for opening and closing the die members, means for operating the linkage means, a pair of pivoted handles attached to the body member, a ram longitudinally movable in the body member and pivoted to the handles so that actuation of the handles causes the ram to move longitudinally with respect to the die members, and means cooperating with the ram to deform the work piece whereby a connector may be inserted in the tool and the jaws and ram actuated to deform the connector onto the conductor.
  • a tool for deforming an electrical connector onto a conductor including: a body member, a plurality of jaws forming die members, said jaws pivoted to the body member with one end of each jaw therein, linkage means secured to the jaws for opening and closing the die members, means for operating the linkage means, a ram longitudinally movable in the body member, means to actuate the ram longitudinally with respect to the die members, and means cooperating with the ram to deform the work piece whereby a connector may be inserted in the tool and the jaws and ram actuated to deform the connector onto the conductor.
