CRIMPING TOOL WITH STRIP FEED MECHANISM Filed March 23, 1964 4 Sheets-Sheet 4 United States Patent 3,230,758 CRIMPING TOOL WITH STRIP FEED MECHANISM Martin Luther Kliugler, Hershey, Pa., assignor to AMP Incorporated, Harrisburg, Pa. Filed Mar. 23, 1964, Ser. No. 353,871 3 Claims. (Cl. 72-410) This invention relates to crimping devices for crimping electrical terminals in strip form onto the ends of wires.
An object of the invention is to provide a crimping device having an improved feeding means for feeding terminals in strip form towards the crimping dies. A further object is to provide an improved hand tool for crimping electrical terminals onto wires. A still further object is to provide a manually actuated hand tool for crimping terminals in strip form onto wire ends including means for feeding the strip during each operating cycle of the tool.
These and other objects of the invention are achieved in a preferred embodiment thereof comprising a hand tool having a C-shaped frame member on which a fixed crimp ing die is mounted. A ram is slidably contained in the frame member for movement towards and away from the fixed crimping die. A crosshead is secured to the ram and extends laterally on each side of the path of reciprocation of the rain, this crosshead including a movable crimping die for cooperation with the fixed crimping die to crimp a terminal onto a wire end. Uncrimped terminals in strip form are fed across the crosshead to position the leading terminal of the strip between the crimping dies by a feeding means which comprises a feed slide mounted on the crosshead and reciprocal, with respect to the crosshead, towards and away from the path of movement of the ram. This feed slide is provided with a pawl which engages the strip and advances the strip across the crosshead during movement in one direction. The feed Slide is reciprocated by means of a wire spring which is secured at one end to the slide and extends obliquely towards the frame of the tool. The opposite end of this spring is secured to the frame at a location remote from the crimping dies. The preferred embodiment of the invention includes a manually actuated toggle mechanism for moving the crosshead towards and away from the fixed die. The arrangement is such that during movement of the crosshead towards the fixed die, the wire spring is straightened and urges the feed slide towards the path of reciprocation of the ram. When the crosshead moves in the opposite direction, the wire spring is flexed and moves relatively away from the ram thereby to move the feed slide away from the path of reciprocation of the ram.

FIGURE 2 is a side View taken along the lines 2-2 of FIGURE 1;
FIGURE 3 is a fragmentary frontal view of the tool of FIGURE 1 showing the position of the parts of the strip feed mechanism at the beginning of' the operating cycle;
FIGURE 4 is a view similar to FIGURE 3 but showing the positions of the parts after closure of the tool handles;
FIGURE 5 is a fragmentary perspective view of the crosshead on which the strip feed mechanism is mounted;
FIGURE 6 is a perspective View of a section of terminal strip;
FIGURE 7 is a view taken along the lines 77 of The strip 2 comprises a pair of parallel carrier or side strips 4, 6, and contact terminals 8 which are integral with the carrier strip 4. The two carrier strips are connected together by means of transverse rungs 14 and the terminals are disposed between adjacent rungs. Carrier strip 4 is provided with spacedapart pilot holes 12 formed during the manufacture of the strip which are utilized in feeding the strip as described below. Each terminal has a pair of upstanding ears 18 adjacent to the carrier strip 4 which, during crimping, are curled towards each other and downwardly into surrounding relationship with a wire.
The disclosed form of crimping tool has a C-shaped frame member comprising a web 20, and upper arm 24, and a lower arm 22. A rod 26 secured to the lower arm 22 by means of pins 28 extends downwardly as viewed in the drawing constituting an integral extension of the frame. An L-shaped die 'holder 30 is mounted on the underside of upper arm 24 by means of a screw 32. A depressor 36 (the function of which is fully described below), and a fixed crimping die 38 are mounted on the die holder 30 by means of a screw 34 which extends through the depressor, through the die 38, through a suitable spacer 44 and into the depending arm 40 of the die holder. As shown from FIGURE 1, the lower end of this arm 40 is provided with slots 42 which provide clearance for the transverse rungs 14 of the terminal strip when the leading terminal of the strip is crimped.
A ram 46 is slidably contained in an axial bore in rod 26 and extends upwardly as viewed in FIGURE 2 beyond the lower arm 22. A crosshead generally indicated at 48 is secured to the upper end of the ram 46 and comprises an L-shaped block 50 mounted on the upper end of the ram and a crosshead plate 74 (FIGURE 5) secured to the block 50. Ears 52 extend from block 50 on each side of the ram and handles 56 are pivotally connected to these ears by means of pins 58. Each handle 56 is pivotally connected intermediate its ends by means of parallel link plates 60 to the lower end portion 66 of the rod 26.. In the disclosed embodiment these parallel plate links are pivotally connected to pins 62 in the handles at one end and to a common pivot .pin 64 on rod portion 66 at their opposite ends. It will be apparent that the arrangement shown constitutes a toggle type linkage which is arranged such that when the handles are moved relatively towards each other, the block 50 and the crosshead 48 will be moved upwardly towards the upper arm 24 of the frame. In order to return the handles to their initial position, return springs 68 are provided which are connected at one end to the pivot pins 58 and at their opposite ends to a yoke 70 mounted on the rod portion 66.
It is desirable in connector crimping tools to provide a full stroke compelling mechanism between the handles which insures that after commencement of a crimping operation, the dies will be moved towards each other by the requisite amount required to crimp the terminal. A mechanism of this type 72 is provided on the disclosed tool and comprises a telescoping ratchet mechanism of the general type shown in US. Patent No. 2,560,318.
The crosshead frame plate 74 is secured to mounting plate 50 by means of a screw 76 and extends laterally on each side of the ram 46. On its rearward side, crosshead plate 74 has a vertical slot 78 within which the lower or movable crimping die 82 is contained. This crimping die extends upwardly from a flange 81 which, in turn, is integral with a plate 80. The plate 80 is interposed between the upwardly extending arm 52 of mounting block 50 and the rearward side of the crosshead plate 74, the mounting of the parts being achieved by means of the screw 76 which extends through aligned openings in the 3 crosshead plate 74, the die plate 80, and is threaded into the arm 52.
The terminal strip is fed over the upper surface portions 83, 85 of the cross head plate from right to left in FIGURE 1 by means of a feed slide 84 (FIGURE 5 This feed slide comprises a plate disposed against the frontal surface of the crosshead plate on the left-hand side thereof and normally projects leftwardly beyond the end of the cross-head plate. Feed slide 84 has a rightwardly extending guide bar 86 integral therewith which is slidably received in a groove 88 on the face of the crosshead plate. A flange 94 extends rearwardly from the lefthand side of the feed slide and bears against the face of an L-shaped block 96, the flange 94 of the feed slide being supported by a ledge on this L-shaped block as indicated at 98. A screw 100 is threaded through the block 96 and into the flange 94 of the feed slide to secure these parts together.
In order to prevent leftward movement of the feed slide and the block 96 beyond the position shown in FIGURES 1 and 3, a stop is provided in a form of a screw 102 which extends through an oversized opening in the block 96 and is threaded into the crosshead plate on the left-hand side thereof.
Reciprocation of the feed slide is achieved by means of a wire spring 104 which extends into a slightly oversized opening on the underside of the block 96. When the parts are in their normal position (FIGURE 3) this spring extends downwardly and slightly convergently with respect to the central axis of the tool towards the left-hand pivot pin 62. The spring 104 extends through a guide 108 mounted on the left-hand pin 62 then extends between the link plates 60 and towards the pin 64. The lower end of this spring is curled around and secured to the fixed pin 64 on the frame extension 66. Spring 104 is advantageously of spring steel and is capable of undergoing repeated fiexure without failure.
In operation, when the handles 56 are closed to move the crosshead upwardly from the position of FIGURE 3 to the position of FIGURE 4, the upper end 106 of the spring 104 is forced to move relatively rightwardly towards the center of the tool, that is towards the crimping dies. Such movement of the upper end of the spring is brought about by virtue of the fact that its lower end 110 of the spring is secured to the pivot pin 64 so that the spring is partially straightened as is apparent from a comparison of FIGURES 3 and 4. It should be added that the guide member 108 through which the spring extends assists in effecting the inward movement of the upper end of the spring since this guide member moves rightwardly towards the axis of the tool along an upwardly arcuate path. The rightward movement of the upper end 106 of the spring during upward movement of the crosshead causes the feed slide 84 to move rightwardly from the position of FIGURE 3 to the position of FIGURE 4. After completion of the crimping operation, the operator releases his grip on the handles 56 which then move apart under the influence of the springs 68. During such movement of the handles, the crosshead moves downwardly towards the pivot pin 64 and the spring 104 is forced to flex resulting in relative leftward movement of the upper end of the spring and the feed slide.
The feed slide is provided with a relatively deep slot 112 extending parallel to the crosshead plate and a feed pawl 114 is pivotally mounted in this slot on a pivot pin 116. A torsion spring 118 bears against the underside of pawl 114 and normally urges this pawl in a clockwise direction about its pivotal axis 116. The left-hand side of pawl 114 is relatively steep so that during leftward movement of the feed slide from the position of FIGURE 4 to the position of FIGURE 3, the pawl will enter one of the pilot holes and drag the terminal strip leftwardly. The right-hand side of the pawl slopes gently towards the upp r surface of the crosshead plate so that the slide an 4- i t move rightwardly and the pawl will be depressed beneath the carrier strip during such movement.
A stop pawl is provided on the right-hand side of the tool frame as viewed in FIGURE 3 to prevent rightward movement of the strip when the feed slide is moved right- Wardly during upward movement of the crosshead. This stop pawl 128 has a rightwardly extending arm pivot= ally mounted on a fastener 138 within a slot 124 in a housing 122. This housing is secured to the crosshead plate by the fastener 138 which extends from the rearward side of the crosshead plate through the crosshead plate and through a threaded opening in housing 122.-
A cover plate 144 mounted on the face of crosshead plate 74 has a rearwardly extending flange 146 on its upper end which projects over the carrier strip 4 and which has suitable slots 147 through which the pawls 114, 128 project. The function of this flange is to hold the carrier strip against the upper surface portions of the crosshead plate and to guide the strip during feeding.
The cover plate 144 is pivotally mounted on its righthand side on the crosshead plate 74 by means of a fastener 172. When the terminal strip is initially threaded through the tool, the cover plate 144 must be raised in order to permit the strip to be positioned beneath the flange 146 of the cover plate. The raising and lowering of the cover plate 144 is facilitated by a camming and latching mechanism comprising a sector plate 178 which is secured to a screw 188 (FIGURE 7) which extends through the pin 58. Screw 188 is normally biased leftwardly in FIGURE 7 by means of a coil spring 180 interposed between the head of the screw 188 and one of the surfaces of the handle 56. It will thus be apparent that if the head of the screw 188 is pressed, the sector plate 178 will move rightwardly from the position shown in FIGURE 7. A pin 182 is provided in the sector plate and extends towards the cover plate 144. Normally this pin is disposed in a slot 184 (see FIGURE 3) in the cover plate and maintains the cover plate in its lowered position and in engagement with the terminal strip. When it is desired to raise the cover plate, the head of the screw 188 is pushed rightwardly in FIGURE 7 and the sector plate is swung in a clockwise direction until the pin 182 moves beyond a cam surface 176 on the lower side of the cover plate. Finger pressure on the screw 188 is then released to permit the sector to move relatively towards the cover plate until pin 182 is disposed beneath the cam surface 176. The sector plate is then swung in a counterclockwise direction causing the pin to move relatively over the camming surface 176 and raise the cover plate. When it is desired to lower the cover plate the head of the screw 188 is merely pressed and the cover plate is pulled downwardly against the upper surface of the crosshead by means of a spring 186 which is secured to the left-hand side of the cover plate and to the screw 188. After the cover plate has moved back to its normal position (FIGURE 1) the pin 182 is moved into the slot 184 under the influence of the spring 180 to lock the cover plate in its lower position.
At the time of crimping the leading connector or terminal onto a wire, it is necessary to shear this leading connector at the rearward end of its ferrule forming portion 18 from the section 10 of the strip. This shearing operation is carried out by means of a shear plate disposed in front of the fixed crimping die 38 in a location such that upon downward movement of the plate, the section 10 of the terminal strip will be displaced downwardly relative to the terminal which will be positioned and held between the crimping dies. Plate 160 is disposed immediately beneath a leg 162 on depressor 36 so that upon upward movement of the crosshead and the plate, the shearing plate will be engaged by this leg and moved relatively downwardly with respect to the movable die. Shearing plate 160 has an integral spring arm 164 which extends rightwardly above the crosshead. The end of this arm has a forwardly extending flange .5 166 which is bent downwardly in front of the crosshead plate and is secured to the crosshead plate by a screw 170.
In use, the parts will normally be in a position shown in FIGURE 1 with the crosshead in its lowered position and with an uncrirnpe-d terminal position between the crimping dies. The operator first locates the end portion of a wire between the crimping dies and above the ferrule forming portion of the terminals. The handles are then closed to cause upward movement of the crosshead and the lower crimping die with concomitant rightward movement of the feed slide relative to the crosshead plate. The rightward movement of the feed slide results from the fact that the pin 64 moves relatively downwardly from the position of FIGURE 3 to the position of FIGURE 4 and the spring 104 is thereby partially straightened. Since the ends of this spring are fixed, the upper end of the spring 106 is forced to move rightwardly in FIGURE 3 moving the feed slide in the same direction. The pawl 114 is depressed during this portion of the cycle and moves beneath the carrier strip 2 until this pawl moves beneath the next adjacent pilot ball in the strip at which time it springs upwardly and enters next adjacent hole.
After the terminal has been completely crimped onto the wire, the handles are permitted to return to their initial position under the influence of the springs 68. During the portion of the cycle, the spring 104 returns to its original curvature (FIGURE 1) and causes the feed slide to move leftwardly thereby advancing the terminal strip a distance equal to the spacing between the terminals. The feed slide is thus reciprocated by the flexing and unfiexing of the spring 104 as a result of the closing and opening of the handles.
Change in construction will occur to those skilled in the art and various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description' and accompanying drawings is offered by way of illustration only. The actual scope of the invention is intended to be defined in the following claims when viewed in their proper perspective against the prior art.
