  • elevator 9 4 is retraced so as to retract the toggle lock mechanism allowing downward movement of carrier bed 62'.
  • the termination of the second connector 14 forms a double-ended harness ready for ejection from the transport assemblies 50, 52.
  • ejection arms 100 are extended to overlie the connectors 14, their spring-loaded pawls 184 being retractable as they are passed over the connector housings.
  • pawls 184 clear tne remote end of connectors 14
  • ejection arms 100 reverse direction and pawls 184 pull connectors 14 onto their respective eject tracks 104, for transport to 90 degree roll-over stations 107 (see FIG. 1).
  • FIG. 5a An example of a roll-over station 107 is shown in FIG. 5a inoorporatea with an arm 100.
  • arm 100 is mounted for reciprocal extension and retraction indicated by arrow 240 under tne ariving force of actuator 242.
  • a second pawl 244 is provided to provide gripping of connector 14.
  • the leaaing pawl 184 is preferably mounted on an extendable section 246 of eject arm 100, while tne second pawl 244 is fixed in a stationary position.
  • a motor 250 is energized to arive tne gear 252.
  • Actuator 242 and eject arm 100 are rotatably mounted at eacn end by rotatable supports 254, 256. As indicated, tne leading support 254 is rotatably driven by gear 252. Accordingly, connector 14 is rotatea 90 degrees in a plane extending perpendicular to eject track 104. Limit switches 260 deenergize motor 250, wnen the proper angular rotation is acnievea. Upon rotation, actuator 242 is again energizea to introduce connector 14 to a delivery track 110, which will be explainea below witn reference to FIG. 8a.
  • a second roll-over station 170 must be provided for a second connector 14, when a double-ended harness is produced. While a particular roll-over station 170 is shown in FIG. 5a, otner arrangements will become apparent to tnose skilled in the art.
  • connectors 14 Upon leaving stations 107, connectors 14 are positioned with tneir mating ends 24 upwardly directed, and wires 12 extending between connectors 14 forming a downward loop, as shown in FIG. 7a.
  • tne secono modular transport assembly designated generally at 52', includes wire cutting and stripping tooling, rather tnan tne mass termination tooling referred to above.
  • wires 40 nave been extended past termination station 58 by tne first transport assembly 50, upon its retraction to a point adjacent loading station 54. Thereafter, as shown in FIG. 6a, opposed moving wire comb members 130, 132 are extended toward the wire supply 92. As indicated in FIG.
  • tne wire combs are brouht into engagement witn eacn otner, ana are thereafter retracted to their initial position, being moved toward first transport assembly 50.
  • wires 40 nave been combed and aligned, ready for cutting and stripping operations.
  • Sensors locateo in wire combs 130, 132 send a cycle completion signal to sequence control 240, upon returning to their initial position.
  • sequencing control 240 energizes elevator 94, raising tooling head 246 to engage wires 40, and raising lower wire clamp 2 48 to also engage wire 40.
  • Tooling head 246 and wire clamp 248 are both contained on a moveable bed 250. Pull down solenoid 256 is in turn fastened to bed 250 to ensure retraction tnereof at the proper time.
  • Sensors located witnin solenoid 256 indicating full upward extension of tooling nead 246 send a signal to sequencing control 240, initiating downward extension of actuator 80' (FIG. 6c).
  • control 240 energizes actuator 222 lowering wire clamp 214 to press wires 40 against tne lower wire preparation module.
  • Cutting blades 124 and stripping blades 126 are thereby lowered for engagement with cutting edge 246c and lower stripping blade 126'. respectively.
  • upper wire clamp 249 is brought into engagement witn its mating counterpart 248, so as to firmly engage wires 40.
  • a signal is sent to sequencing control 240 to initiate the rightward extension of actuator 128. This action moves wire clamps 248, 249 toward the right, away from stripping blades 126, 126', to effectively strip the newly formed free enus of the harness wires, as inaicatea in FIG. 6e.
  • connectors 14 are located at a peg removal station 112, wnereat knife-like peg-removing blades 118 are lowereo to sever selected polarizing pegs 116 from tne upper and lower lawning surfaces 20, 22, respectively.
  • the pegs 116 have been positionea so as to extern beyond, but not overlie mating edge 24.
  • the positioning of connectors 14, to withstand tne force of severing blades 118 is ensured by delivery track 110.
  • Blades 118 are mounted to a press-like actuator 119 for downward movement across top and bottom connector surfaces 20, 22. Accordingly, it is important that track 110 is more narrow than the body of connector 14, and prevents sideways rocking ot tnat body during peg removal.
  • Connectors 14 have alignment taps 260 extending from mating ena 24 to form an alignment cnannel 262 extending tnerealong.
  • Track 110 has an upper rail member 266 complementarily shaped witn cnannel 262, for a close-fitting reception therein.
  • Track 110 furtner includes second and third rail members 270, 272 wnicn engage and support tne wire receiving end 26 of connector 14 immediately adjacent the top and bottom connector surfaces 20, 22. In effect, lower rails 272, 270 oppose upper rail 266 to form a connector receiving cavity corresponding to tne profile of connector 14.
  • connectors 14 are slia along track 110, for presentation to wep removal station 114 wnicn includes a predetermined plurality of web removing blades 120. As indicated in FIG. 8b, the web removal blades are lowered into the mating end of connector 14, so as to remove selected web portions 44, to form a plurality of connector modules 46 as indicated by tne dotted lines of FI G . 8c.
  • the phantom lines 280 indicate the region of material removed from connector nousing 16 by blades 120 correspondig to a web portion 44.
  • tne particular connector modules 46 formed by blades 120 have a vertically elongated side profile, particularly for a two-circuit connector comprising one upper terminal ana one lower terminal.
  • the arrangement of delivery track 110 is particularly advantageous in tnat it provioes reliable sliding transport of the connector module, without rocking about any of its tnree mutually ortnoconal axes, one or which lies in tne direction or track 110.
