Definitions

  • Another object of this invention is the provision of a compression tool having means for automatically releasing'a retained article after it has been fully compressed. Still other objects of this invention include the provision ofvintegrally mounted article retaining means, for crimping tools, which is relatively inexpensive, effective in Operation, and easy to use. 7
  • a feature of this invention is the use of a spring-loaded retention jaw positioned between the fixed jaw and the movable jaw of a compression tool in such manner that it is resiliently urged against one of the other two jaws so as to grip an article between itself and the opposing jaw.
  • FIGURES 3 to 6 represent partial vertical section drawings illustrating sequential steps in a crimping cycle preformed by the tool shown in FIGURE 1;
  • FIGURE 7 is a vertical section view of a compression tool constructed in accordance with another embodiment of this invention.
  • FIGURE 1 may be seen to comprise a body member 1 on which are mounted a fixed jaw 30, a movable jaw 12, and an operating handle 2.
  • the operating handle 2 is coupled to movable jaw 12 by means of a pinion 11, and to the body member by an articulating link 3 which is pinioned at 4 and 5, so as to advance the movable jaw toward the fixed jaw when the handle is moved in the direction of arrow F.
  • a tension spring 10 is coupled at one end to the body member 1 and at the opposite end to handle 2 so as to return the jaws of the tool to open position when an applied force acting in the direction of arrow F is released.
  • the operating handle 2 is provided with a ratchet 8 and the body member is provided with a cooperating pawl 6 which is pivoted to the body member by pinion 7 and is spring-loaded by tension spring 9.
  • This ratchet and pawl arrangement assures that once a compression cycle of the tool has begun, the jaws must be moved to fully closed position before they can again be opened.
  • a slotted guide member 13, fastened to the body member 1 by means of pins 14 is provided as a means for retaining and guiding the motion of movable paw 12.
  • a retention jaw 18 may be seen to be positioned between fixed jaw 30 and movable jaw 12.
  • the retention jaw is positioned relative to movable jaw 12 by means of a pair of pistons 17. which are received in a pair of cylinder bores 16 in the body 15 of movable jaw.
  • Compression spring 19 positioned between pistons 17 and the bottoms 20 of bores 16 resiliently couple the movable jaw 12 to retention jaw 18.
  • detent spring 23 having a latching lip 24 and anchor portion 22 is secured to the bottom portion 20 of movable jaw 12 by means of a staking pin or rivet 21.
  • detent spring 23 will be deflected so as to snap lip 24 into engagement with cooperating shoulders 25 on jaw 18. The purpose of restraining the relative motion of jaws 12 and 18 in this manner will be made apparent by the descrip tion of the operation of this tool which follows below.
  • a push button 26 which operates through an aperture 26a in guide block 13, is provided to permit manual deflection of latch 23, so that lip 24 may be disengaged from shoulder 25 when necessary in the course of operation of this tool. Operation of the embodiment of this invention represented by FIGURE 1 may be most readily explained with reference to FIGURES 3 through 6 as follows:
  • FIGURE3 illustrates the relative positions of fixed jaw 30, movable jaw 12, and retention jaw 18 at the beginning of a compression cycle.
  • jaws 12 and 13 are separated by a substantial distance in accordance with the design of the compression tool operating mechanism, and retention jaw 18 is held in close proximity to movable jaw 12 by interengagement of detent lip 24 with latching shoulder 25; as a result of this relative po sitioning of jaws 18 and 12, compression springs 19 are under significant compression between pistons 17 and the bottom portion 20 of bores 16.
  • These grooves are adapted to cooperate with mating grooves 31 on jaw 30 for compressing connectors therebetween.
  • Grooves'27 may be provided as shown with a stop shoulder29 which is adapted to "engage a cooperating shoulder (not shown) on connector 28 for longitudinally positioning the connector.
  • the push button 26 is pressed inwardly toward jaw 12 as shown by the direction of the horizontal arrow in FIGURE 4, to deflect spring arm 23 and disengage lip 24 from shoulder 25. Disengagement of latch 23 permits-jaw 18 to move in the upward direction shown by the vertical arrowat the right of the jaw, under the resilient pressure of compression springs 19, so as to resiliently grip the connector 28 between groove 27 on jaw 18 and groove 31 on jaw 30.
  • the force applying mechanism of the compression tool may be operated to advance movable jaw 12 toward fixed jaw 30.
  • the force rate of compression springs 19 will be resisted by connector 28 until the force transmitted from jaw 12 to jaw 18 is sutlicient to compress the connector between cooperating grooves 27 and 31, as shown in FIGURE 5.
  • latch 23 will again engage lip 24 with shoulder 25 to effectively lock jaw 18 to jaw 12.
  • FIGURE 7 through 11 represents an alternative embodiment of this invention in which parts corresponding exactly to those illustrated in the embodiment of FIG- URE 1 are numbered identically while substantially similar parts are likewise denoted by identical numbers which are further distinguished by a superscript prime marking, and parts distinctive to this embodiment are denoted by reference numerals 33 through 41.
  • the compression tool of this embodiment is pro- 'vided with a movable jaw 12' and fixed jaw 33, which differ from their counterparts in FIGURE 1 primarily in their shape.
  • the retention jaw 34 is hingedly mounted at 35 in the manner of a flap, and is provided with a torsion spring 38 which bears against surface 39 of body member 1 to resiliently urge jaw 34 against jaw 33.
  • the retention jaw is provided with a protruding handle portion 41 which permits it to be manually pivoted about pin 35 so that it may be separated from jaw 33. It is further provided with a plurality of apertures 36 which are substantially aligned with die positions 31' in jaw 33 and are adapted to permit the indenting dies. 36' to pass through them.
  • FIGURE 8 the jaws 12' and 33 are shown separated by a substantial distance, as they would be at the beginning of a compression cycle.
  • Retention jaw 34 has been shown resiliently deflected out of engagement with jaw 33 by a downward force acting on handle portion 41, so that an electrical connector may be inserted between jaws 34 and 33 and positioned within one of the receiving grooves 27 in jaw 34.
  • movable jaw 12' may be advanced by operation of thecompressioirtool thenormal manner, until indentQrs-36' 'have passed through apertures 36 injaw 34, and have deformed connector 40 about an-inserted stranded wire 42 as shown in FIGURE l0.
  • FIGURE'II illustrates the endof'a compression cycle of this embodiment, at which point the jaws -33'and'12' havebeen separated by continued operation .of thetool mechanism, and jaw 34 has been manually deflected by a'force applied to handle 41 to permit removal-of crimped connector 40-and wire 42 and-insertion of a fresh connector i v I
