ABSTRACT - CANADA
Apparatus for applying a tubular insulating housing to an electrical terminal secured to the end of a wire comprising first and second axially spaced pairs of jaws overlying a terminal supporting bed, the jaws being relatively movable together transversely across the bed to grip opposite lateral sides of a terminal and wire immediately behind the terminal respectively, the jaws of the first pair of jaws being of generally V transverse cross-section to raise the terminal above the bed and to adjust precisely the transverse and rotational orientation of the terminal during engagement by the jaws, means to locate a housing in axial alignment with the terminal and means relatively to move the housing and the terminal towards each other, the jaws of the first pair of jaws being separable on initial receipt of a free end of the terminal in the housing to permit complete insertion of the terminal into the housing.

Description
~069t~82 The invention relates to apparatus for applying a tubular insulating housing to an electrical terminal secured to the end of a wire.
One such terminal is formed from sheet metal with a central web portion opposite lateral edges of which are rolled over axially of the wire to define a pair of spring arms having free ends which co-operate with the web resiliently to grip a tab inserted between the arms and the web.
A problem encountered with such apparatus is in accurately supporting the terminal in alignment with the pod immediately prior to application of the housing. This problem may be exacerbated ~here the terminal is of small size.
In a prior apparatus, described in our Canadian B Patent No, 898498 ~7't, a terminal su~port comprises a pair of parallel fingers having notched ends each o which engage in and behind respecti~e spring rolls. A
housing support is moved axially towards the terminal support to force the housing over the terminal via the terminal front end.
A disadvantage of such apparatus is the difficulty in positioning (and retaining) the terminal on the fingers of the support which must often be done manually. Further-more, axial strain imposed on the wire to locate or retain the terminal on the support may result in tilting the free ~ end of the terminal out of alignment with the housing.

a tu~ular insulating housing to an electrical terminal secured to the end of a wlre comprises first and secon~ -... . . .

axiall~ spaced pairs of jaws overlying a terminal supporting bed, the jaws being relatively movable together transversely -across the bed to grip opposite lateral sides of a terminal and ~7ire immediately behind the terminal respect-ively, ~aws of the first pair of jaws being of generally V transverse cross-section to raise the terminal above the bed and to adjust precisely the transverse and rotational .
orientation of the terminal during engagement by the ja~ts, means to locate a housing in axial alignment with the terminal and means relatively to move the housing and the terminal towards each other, the jaws of the first pair of jaws being separable on initial recei~t of a free end of the terminal in the housing to permit complete insertion of the terminal into the housing.
After release of the first jaws the termina1 is restrained from axial movement with the housing during the final stages of insertion only by the wire gripped by the second pair of jaws.
A specific example of apparatus according to the Zo invention will now be described with reference to the accompanying drawings in which~
Figure 1 is an axial cross-sectional view of the apparatus;

The apparatus comprises a rectangular base plate 11 carrying a channel section first support block 12 and a second support block 13 located forwardly of the first support block and a through bore 14 axially aligned with the channel 15 of the first support block. The channel 15 is covered by a plate 19 and an upper part of the second support block has a channel section 16 extendin~ -into a for~Jardly projecting part 17 also covered by a plate 18.
A first paix of jaw blocks 21 are mounted for limited transverse sliding movement together and apart on plate 19 and are biased together by compression springs 22.
Adjacent ends of the blocks have opposed grooves 23 receiving a plate 24 providing a terminal support bed and opposed V-section jaws 25 overlying the plate 2 Adjacent rear faces of the blocks are chamfered at locations below the grooves to provide cam surfaces 26.
A second pair of jaw blocks 31 are mounted for limit~d transverse sliding movement together and apart on block . 13 and are biased together by tension spring 32. Wire gripping jaws 34 are carried by respective bloc]cs and overlie plate 18. Adjacent rear faces of the blocks are chamfered providing cam surfaces 33.

A housing insertion ram 44 is mounted for reciprocal movement alon~ the channel and is connected through a sleeve mounted return spring 45 to a pneumatic piston and cylinder 46 carried by bracket supports 49 fixed to base plate 11. A first terminal jaw opening ram 47 having a camming leading end 48 is fixed to a lower ~ .
side of the ram 44 which is rebated at 50 to pxovide a ~ .
clearance for the plate 24.
A second terminal jaw opening ram 52 having a camming leading end 53 is mounted for relative sliding movement between the ~irst jaw opening ram 4.4 and plate 19 and is .
connected by an actuating pin 54 to a second pneumatic :
plston and cylinder 55 carried by bracket supports 49.
A third wire jaw opening ram 56 ~s mounted for : -axial movement on an end of actuating pin 45 which extends through bore 14 and channel 15 to the pneumatic cylinder 55. A compression return spring 57 is located between an .~ .

Guard plates 61 are mounted on the front o the apparatus on each side of the jaws and guards 62,63 are mounted on the base plate on each side of the actuating pin and return spring.
In operation of the apparatus, a terminal attached to the end of a wire is laid on and generallv parallel to the bed bet~een the separated jaws of each pair. The jaws are then permitted to close by release of pressure from cylinder 55, the irst jaws grippLng the terminal and the . .

second jaws qripping the wire immediately hehind the terminal. During closure, the first jaws raise the terminal from the bed and orientate the terminal accurately as a result of their V-section. The ram 44 is then advanced by the first piston and cylinder to push a housing fed by the chute over the free end of the terminal. On initial receipt of the free end of the terminal in the housing, the first jaws are separated by engagement between camming end 48 of ram 47 and cam surfaces 26 on jaw blocks 21 to release the terminal to permit complete insertion of the termlnal into the housing, the terminal being restrained from rearward axial movement during the final stages of insertion only by the wire gripped by the second jaws. After complete insertion, the second and third jaw opening rams are operated during retraction of the housing ram to separate the second jaws releasing the wire and terminal and to retain the first jaws separated to permit location of a further terminal between the jaws.
