ELECTRICAL HARNESS FABRICATION MACHINE

Abstract: An electrical harness fabrication machine which produces harnesses which comprise ribbon cable having a connector (14) at each end. Each connector has a housing with terminals loaded therein. Prior to termination to the cable, the terminals are partially preloaded into their respective housings so that conductor engaging ends thereof are presented to a termination station for mass termination. A conductor engaging end of the terminals are free standing sections (38) which form an insulation displacement slot there­ between. The termination assembly has a portion adajcent conductor stuffing blades for laterally supporting the conductor engaging ends of the terminals during the termination operation. In addition, pilot members (100, 102) are provided to cooperate with a connector nest (60) having a preloaded connector received therein and the conductors for accurately aligning the conductors, conductor engaging ends of the terminals and the termination assembly with respect to one another.

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to machines or other apparatus for fabricating an electrical harness which comprises a plurality of wire conductors electrically connected to one or more electrical connectors. 2. Brief Description of the Prior Art In order to mass terminate a plurality of terminals to wire conductors, machines have been developed to partially preload the terminals into the terminal receiving cavities a connector housing so that their wire engaging portions extend from the housing. Subsequently, a termination assembly of suitable configuration electrically connects or terminates the wire conductors to the wire engaging portions of the terminal. The partially loaded terminals are then inserted completely into their fully seated position into the connector housing. An example of the above apparatus is disclosed in United States Patent No. 4,335,497. This particular patent shows a termination station whereat one such connector is terminated. One type of terminal which can be used for mass termination is a crimpable insulation piercing type which is disclosed in the above-identified United States Patent No. 4,335,497. Another type of terminal which lends itself to mass termination is one having a wire engaging portion that has an insulation displacement slot. One form of an insulation displacement slot is disclosed in United States Patent No. 4,385,794. The problem with such a terminal design is that the insulation displacement slot is formed from free standing walls. When the wire conductor is being inserted into the insulation displacement slot, the free standing walls comprising the slot tend to move away from one another thereby lessening the reliability of the electrical connection between the conductor core and the terminal. One means of supporting an insulation type terminal during termination is disclosed in United States Patent No. 4,277,124. The terminal is braced by walls formed in the connector housing. This requires a two piece housing design. SUMMARY OF THE INVENTION One object of the present invention is to provide an improved machine for fabricating electrical harness. The present invention is a machine for fabricating an electrical harness including a connector electrically connected to a plurality of insulated wire conductors, said connector having a housing with a plurality of terminal receiving cavities therein and a plurality of terminals mounted in said cavities, each terminal having a wire engaging portion in the form of an insulation displacement slot and being movable between a partially preloaded position relative to the housing wherein the wire engaging portions extend out of the housing to an inserted position wherein said terminals are fully seated within their respective cavities, said machine characterised by a connector nest for holding and positioning a partially preloaded connector having a floor defining a support surface for said connector, a termination station whereat a partially preloaded connector is electrically connected to a plurality of wire conductors, a wire conductor source for storing wire conductors and guiding them to the termination station, wire clamping means for releaseably holding the wire conductors at the termination station, a termination assembly including a termination head with a plurality of wire stuffing blades, said termination assembly being movable between a normal position wherein the blades are immediately over the wire conductors and wire slots downwardly to a terminating position simultaneously pushing the wire conductors into their respective wire slots, said connector nest and termination assembly being mounted for up and down relative movement between a first position wherein said nest is spaced from said termination assembly and a second position wherein said conductors and wire slots are terminated, means for feeding a predetermined length of wire conductors, cutting means for cutting the wire conductors at the predetermined length after being terminated, and terminal insertion means for inserting the terminals to their inserted position, said wire engaging portion including a base with two upstanding opposed members each having a wall defining the bight parallel and spaced from each other, each wall having an inwardly directed plate at one end, the plates being spaced apart a distance less than the width of the conductor of the insulated wire so as to define an insulation displacement slot; and said termination head including wall support means mounted on both sides of each blade, and a space between each blade and wall support means for receiving a terminal wall therein so that the wall support means are positioned immediately adjacent the outside of the terminal walls when said termination assembly and said connector nest are in their second position; whereby, when said termination head is moved to its terminating position, the wall support means laterally brace the terminal walls to prevent the terminal walls from moving outwardly away from each other. The present invention is also a termination head for moving an insulated conductor into an insulation displacement slot of an electrical terminal, said terminal including insulation displacement slot means formed between two slot forming sections spaced apart a distance less than the width of the conductor, said termination head including a blade for engaging a conductor, said head being movable between a first position wherein the blade is spaced from said conductor and slot means downwardly to a second terminating position wherein said blade pushes the conductor into the slot means, said slot means displacing the insulation to electrically contact the conductor, characterised by said termination head including terminal support means on both sides of said blade so that the support means are positioned immediately adjacent the outside of the sections when the head is in the second position, whereby the support means laterally brace the sections to prevent outward movement away from each other.

DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now to the drawings, a portion of the machine of the present invention is shown in Fig. 1. In particular, Fig. 1 illustrates the termination station, generally designated 10, whereat an electrical harness is partially fabricated. The electrical harnesses produced by the machine are of the type which is shown in Fig. 2 and is seen to generally include a length of round conductor ribbon cable 12 having electrically connected at either end a first connector, generally designated 14, and a second connector generally designated 16. The ribbon cable 12 has a plurality of parallel side by side insulated wire conductors 18 mechanically held together by insulative webs 20. Portions of the webs 20 are removed to form notches 22 in a manner that is well known in the art. It is to be understood that other types of conductors can be used such as a flat conductor ribbon cable or discrete wire. I. THE CONNECTOR Looking at Figs. 2 and 3, each connector 14 and 16 is seen to generally include an insulated housing 24 having several side by side terminal receiving cavities 26. Each cavity 26 has two windows 28 and 30 axially spaced from one another for purposes which will become more apparent hereinafter. A plurality of terminals 32 are received in cavities 26. Each terminal 32 has a pin receiving end 34 although, it is understood, that the end 34 disclosed herein does not have to be in the configuration illustrated in the drawings. Integrally formed with the pin receiving end 34 is a wire or conductor engaging end which generally includes a base 36 having two upstanding opposed C-shaped conductor engaging members 38. Each C-shaped member 38 has a wall defining a bight and an inwardly directed plate 42 at both ends. The plates 42 at each same end of both walls 40 are spaced apart a distance less than the conductor of the insulated wires so as to define two axially spaced insulation displacement slots 44. Slots 44 are adapted to receive an insulated wire conductor 18 therein and to displace the insulation to contact conductor core. Looking at Fig. 3, the terminal 32 also includes integrally formed crimpable strain relief wings 46 which extend upwardly from either side of base 36 immediately adjacent the C-shaped members 38. Wings 46 are adapted to be crimped around the insulation of the wire conductor 18 when it is received within the slots 44 for the purpose of preventing inadvertent axial pullout of the wire from the terminal 32. It has been found to be advantageous to present the wire engaging ends of terminals 32 outside of the housing 24. Thus, the connectors 14 and 16 are loaded onto the machine with the terminals 32 in a preloaded, partially inserted position as shown in Fig. 3. This preloaded position is defined wherein a locking lance 48 formed on each terminal 32 cooperates with window 28. The terminals 32 are maintained in this preloaded position and their end spacing is maintained by virtue of retaining the carrier strip 50 integrally therewith. Because of this, the terminals 32 will always move in unison while the strip 50 is attached thereto. It is also to be noted that carrier strip 50 has the usual pilot holes 52 formed therein which are normally used in the process of manufacturing terminals. After the conductors 18 are terminated, the terminals are inserted fully into their respective cavities 26 and are held in that position by virtue of the respective locking lances 48 cooperating with windows 30. At some point subsequent to the termination, the carrier strip 50 is knocked off the remaining terminals to produce the harness shown in Fig. 2. II. THE CONNECTOR NESTS Each connector 14 and 16 is adapted to be held and positioned within first and second connector nests, generally designated 60 and 62, respectively. Looking at Figs. 4A and 5A, each nest 60 and 62 is seen to generally include a floor 64 having an end wall 66 extending upwardly therefrom and a ceiling 68 parallel to floor 64 overhanging a part of the length of said floor. The area between the floor 64, end wall 66 and ceiling 68 defines a connector housing receiving recess. The ceiling 68 has a top portion which is slanted at 70 relative to the floor and flat portion 72. Two sets of pilot recesses 76 and 78 are formed in both nests 60 and 62. One set of recesses 76 is formed in the flat portion 72 of ceiling 68. The other set of recesses 78 is formed in the floor 64 so that when the partially preloaded connector 14 or 16 is properly mounted in nest 60 and 62, the pilot holes of the carrier strip 50 are aligned with recesses 78. III. THE TERMINATION ASSEMBLY A termination assembly, generally designated 80, is mounted at the termination station 10 and is movable in two mutually perpendicular directions. In general, the termination assembly 80 is mounted for up and down movement between a first position wherein a nest 60 or 62 is spaced from said termination assembly and a second position wherein the conductors 18 are terminated within their respective insulation dispalcement slots 44. The termination assembly 80 is also movable towards and away from the conductor source (not shown). The termination assembly 80 serves the purpose of positioning the ends 18 of a length of cable 12 relative to the insulation displacement slots 44 and terminating the ends into the slots. As will become apparent hereinafter, termination assembly 80 performs the same function with respect to both connectors 14 and 16 which are received in the respective nests 60 and 62 without altering the level at which the cable conductors 18 are held at the termination assembly 80. Looking at Figs. 4A and 5A, the termination assembly is seen to include a termination head 84 which is a unitary member extending across the entire termination assembly 80 and is moveable therewith. Termination head 84 has a plurality of depending stuffer blades 86 which are adapted to engage the respective conductors and push them into their respective insulation displacement slots 44 when the termination assembly 80 is moved from its first position (Fig. 4A) to its second position (Fig. 4B). A depending wall support portion 88 is formed on both sides of each blade 86. A recess 90 is formed between each blade 86 and terminal wall support portion 88. When the termination assembly 80 is moved from its first position to its second position the walls 40 of the C-shaped members 38 are received in recesses 90 so that the terminal wall support portions 88 are disposed immediately adjacent the outside of the terminal walls as is best seen in Fig. 5B. In this position, the terminal wall support portions 88 laterally brace the terminal walls 40 to prevent the walls from moving outwardly away from each other during the termination operation. As best seen in Figs. 4A and 4B, the termination assembly 80 also includes a pair of crimp punches 92 and 94, one mounted on each side of the termination head 84 for movement therewith. Crimp punch 92 is adapted to crimp strain relief wings 46 on the second connector 16 which is received in nest 62. Crimp punch 94 is adapted to crimp the strain relief wings 46 on the terminals 32 received in the first connector 14 received in nest 60. Because punches 92 and 94 are mounted for movement with the termination head 84, they perform their crimping operation simultaneously with the conductor termination operation when the termination assembly 80 is moved from the first position to the second position. One of the continuing problems of mass terminating a plurality of conductor ends 18 to conductor engaging portions of terminals is the alignment of the conductor ends with said conductor engaging portions. To this end, the termination assembly 80 includes two spring loaded pilot members 96 and 98, each having a plurality of depending pilot posts 100 and 102, respectively. The pilot members 96 and 98 are mounted on the termination assembly 80, one on each side of crimp punch 92 and 94, respectively. Pilot posts 100 are adapted to be received in pilot recesses 76 of the first connector nest 60 and pilot recesses 78 of the second connector 62. Pilot posts 102 are adapted to be received in pilot recesses 78 of the first connector nest 60 and pilot recesses 76 of the second connector nest 62. Both pilot members 96 and 98 are moveable with respect to the termination head 84 and crimp punches 92 and 94. After pilot posts 100 or 102 are received in the pilot recesses 76 formed in the ceiling 68 of the connector nests 60 and 62, respectively, and the termination assembly 80 and nests 60 and 62 are moved to their second position, the pilot member 96 or 98 is retracted and biased against the ceiling 68 so that the termination head 84 and crimp punches 92 and 94 can be moved further toward the floor 64 of nests 60 and 62. This is best illustrated with respect to the first nest 60 in Figs. 4A and 4B. This is also shown schematically in Fig. 6C with respect to the second nest 62. Separate conductor ends 18 are received between depending posts 100 when the second nest 62 or first nest 60 is at the termination station. Pilot posts 102 receive conductors 18 therebetween only when the first nest 60 is at the termination station 10. By so positioning the conductors 18 between posts 100 and 102, the conductor ends 18 are maintained in their proper spaced relationship. Accordingly, when the posts 100 and/or 102 are received in the respective recesses 76 or 78, each conductor end 18 is captured therebetween. An example of this is illustrated in Figs. 5A and 5B. In addition to aligning the conductors 18, the receipt of posts 100 and 102 into recesses 78 of the second nest 62 and 78 of the first nest 60, respectively, serve to align and maintain the position of the terminals 32 with respect to the termination head 84. This is accomplished by virtue of the pilot holes 50 already being aligned with recesses 78 formed in the floor 64 of each nest 60 and 62. Thus when posts 100 and 102 are received in the floor recesses 78 of the second nest 62 and the first nest 60, respectively, the insulation displacement slots 44 are positively positioned with respect to the termination head 84 and the conductor ends 18. Adjacent the termination assembly 80 and on either side thereof, are two clamping means. One clamping means is located between the termination assembly 80 and the conductor source (not shown) and includes a lower stationary gripping member 104a and a moveable upper gripping member 104b. The top surface of stationary lower gripper 104a defines a conductor supporting surface. The other clamping means is mounted on the other side of the termination assembly 80 and has a moveable lower gripping member 106a which is moveable with the first connector nest 60 and whose top gripping surface is aligned with the floor 64 of nest 60. The top gripping member 106b moves up and down with the termination assembly 80. The gripping members 106a and 106b move together to hold the cable 12 when the first connector 14 is being terminated. IV. MOVING MEANS Looking at Fig. 1, the machine of the present invention performs more functions than that effected at the termination station 10. There are functions also performed upstream (i.e., to the left of the termination station) and downstream (i.e., to the right of the termination station). The termination station 10 is but one location on the machine which performs a plurality of or stream of operations on connector 14. Spaced from and parallel to this stream of functions are the same operations which are performed on the other connector 16. One location on the other side is a second station, generally designated 108, which initially supports connector 16 when it is first positioned in nest 62. It is found to be desireable to perform all of the termination operations at the one termination station 10. Therefore, it is necessary to move the second connector 16 which is initially received in nest 62 from the second station 108 to the termination station 10. This is accomplished by means of a shuttle assembly, generally designated 100, which includes a support member 112 on which the second connector nest 62 is mounted. Support member 112 is mounted for up and down movement relative to a second member 114 which in turn is slidable along a stationary rail assembly 116 which extends between the second station 108 and the termination station 10. Looking at the termination station 10, the second connector nest 62 has a support member 118 which is connected by virtue of linkage assembly 120 to actuation means (not shown). A shelf portion 122 extends from the linkage assembly 120 which is adapted to engage the second nest support member 112 when it is moved to the termination station 10. Linkage assembly provides up and down movement to both the connector nests 60 and 62. Two parallel spaced apart feed tracks 124 and 126 are mounted immediately downstream of the termination station and second station 108, respectively. The tracks 124 and 126 provide support surfaces for the connectors 14 and 16, respectively, after termination as they are directed to other stations wherein other operations are performed. V. OPERATION Turning now to Figs. 6A-6H, the machine operation is illustrated. Looking at Fig. 6A, partially preloaded connector 14 has been moved to connector nest 60 at the termination station 10 while partially preloaded connectors 16 has been moved to connector nest 62 at the second station 108. The grippers 104a and 104b are holding the cable ends 18 immediately underneath pilot member 96. Gripper members 106a and 106b are open. Connector nests 62 is then moved to the termination station 10 as is shown in Fig. 6B. This is accomplished by actuating the shuttle assembly 110 so that member 114 slides and the rail assembly 116. In order to accommodate connector nest 62 at the termination station 10, connector nest 60 is moved downwardly by virtue of actuating the linkage 120. In addition, termination assembly 80 is moved toward the conductor source a distance such that the ends of conductors 18 now underlie the termination head 84. The relative position of the termination assembly 80 with respect to connector nests 62 as shown in Fig. 6B defines the first position with respect to nest 62. Connector 16 is then mass terminated as is shown in Fig. 6C which defines the second position relative to the connector nest 62 and termination assembly 80. The floor 64 of nest 62 acts as a conductor supporting surface. The termination operation is accomplished by actuating the linkage 120 so that shelf 122 pushes upwardly on the support member 112 so that the nest 62 is forced up towards the termination assembly 80. When this occurs, pilot posts 102 are received within pilot recesses 76 and, upon further upward movement, pilot member 98 is retracted relative to the remainder of the termination assembly 80. As the nest 62 moves further upwardly toward the termination assembly 80, the blades 86 engage their respective conductors 18 and pushes them into their respective insulation displacement slots 44 while crimp punch 92 simultaneously forms the strain relief wings 46 about the insulation of conductor 18. During the termination, the pilot posts 100 are received in recesses 78 through the pilot holes 50 thereby assuring that the conductors 18, termination head 84 and insulation displacement slots 44 are all aligned with respect to one another. The entire termination assembly 80 is raised with respect to nest 62 preparatory to its movement back to the second station 108 as is shown in Fig. 6D. When this occurs, the upper gripper member 104b is raised thereby freeing cable 12 for movement of the connector nests 62 and the attached cable. When the nest 62 is moved to the second station 108, a given length of cable is dereeled an amount equal to the distance between stations 10 and 108. After the connector nest 62 is moved to the second station 108 dereeling the cable 12 therewith, an additional length of wire may be dereeled by actuating a looper assembly 130 which imparts a force transverse to the length of the cable downwardly in a manner which is well known in the art. Immediately thereafter, the termination assembly 80 is lowered so that pilot posts 100 and 102 are received within the notched portion of cable 12. Connector nest 60 is then moved upwardly so that pilot posts 100 received within pilot recesses 76 defining the first position between said first connector nest 60 and the termination assembly 80 as is shown in Fig. 6F. When this occurs, upper gripper 104b is lowered to hold the cable between the termination assembly 80 and the conductor source. In the next step shown in Fig. 6G, the termination assembly 80 is actuated so that the termination head 84, crimp punches 92 and 94 and pilot member 98 are simultaneously lowered. The other pilot member 96 remains biased against the ceiling 68 in a retracted spring loaded condition. The termination head 84, and, in particular, the blades 86, push the conductors 18 into their respective insulation displacement slots 44 while crimp punch 94 simultaneously forms the strain relief wings 46 about the insulation of the conductors 18. As crimp punch 92 travels past the free end of the flat portion 72 of ceiling 68, it cooperates with the free edge thereof to shear cable 12 at the correct length. At the same time gripper member 106a is raised to grip cable 12 against upper gripper member 106b. Fig. 6G defines the second or terminating position of termination assembly 80 with respect to the first connector nest 60. The entire termination assembly 80 and gripper member 106b are raised to the same configuration as was described with respect to Fig. 6F. At this point the operation, both ends of the cable 12 have been terminated to partially preloaded connectors 14 and 16 as is shown in Fig. 6H. Suitable means are then actuated to move the terminated cable downstream on feed tracks 124 and 126 where the carrier stip is removed and the terminals 32 and fully inserted into their respective housings 24. It is significant that during the entire operation at the termination station 10, the cable coming from the conductor source is always held at the same relative height. This aids in the correct alignment and measurement of the cable during the termination operation.
