Vandenburg [57] ABSTRACT Apparatus for terminating tap wires of an electrical coil by insetting connecting devices into a flange of the coil bobbin and concommitantlycrimping each connecting device onto one of the tap wires. Each individual connecting device includes an integral mounting means for mounting the device on the bobbin, and a terminal means which can be engaged with a complementary terminal means to form connections to the coil,

7 Claims, 15 Drawing Figures MACHINE'FOR ASSEMBLING A CONNECTING DEVICE TO AN ELECTRICAL DEVICE BACKGROUND OF THE INVENTION Electrical coils, of the type used in solenoids, motors, and other electrical devices, are usually wound on a bobbin having flanges at each end. It is common practice to mount electrical terminals in one of the bobbin flanges and connect the tap wires from the coil to the terminals by a soldering operation. When the external connections arelater made, the lead wires are then soldered to the same terminals so that the lead wires will be connected to the tap wires of the coil.

The instant inventionis directed to the achievement of an apparatus for terminating the tap wires from an electrical coil. Itis-a further object to provide an apparatus for assembling electrical connecting devices to a coil bobbin and concommitantly forming electricalconnections between the connecting I devices and the tap wires from the coil which is wound on the bobbin.

These and other objects of the invention are achieved in preferred embodiments thereof which are briefly described in the foregoing abstract, which are described in detail below, and which are shown in the accompanying drawing in which:

FIG. I is a perspective view of a preferred form of apparatus in accordance with the invention.

FIG. 2 is a perspective view of an electrical coil wound on a portion 20 of each connecting device thus obviates the necessity of chemically stripping the varnish type insulation from the tap wires.

In accordance with the instant embodiment, the connecting devices are provided as right-hand strip I and left-hand strip 15', the two types having their tab portions I8, 18' extending in opposite directions for reasons which will be apparent from an inspection of FIG. 2.

The general principles of the apparatus aspects of the instant invention will be apparent from a brief consideration of FIGS. 3-7 which show some of the essential structural features in the apparatus and illustrate the manner in which the connecting devicesare inserted into the bobbin and the tap wires connected to the connecting devices. A bobbin 4 is first positioned on a bobbin holder 22 with the heavy flange section 12 facing connecting device strips 15, 15'. The bobbin holder is moved towards the strips and the strips are fed relatively towards the bobbin holder (FIG. 5) until the leading connecting devices of the strips have been inserted into the openings 36 in the flange. The tap wires 34, 34' are positioned in keyhole slots 26, 26' on the ends of

arms

24, 24 which are pivoted on a common axis 25 beneath the bobbin holder 22. After the connecting devices have been inserted into the flange portion 12, the arms 24, 24' are swung inwardly and 7 generally towards the connecting devices (FIG. 6) until the bobbin having connecting devices thereon in accordance with the invention.

FIG. 3 is a fragmentary perspective view showing a bobbin holder and an associated pair of wire positioning arms, which are parts of a preferred form of apparatus in accordance with the invention and showing a bobbin exploded from the bobbin holder.

FIGS. 4-7 are views similar to FIG. 3 but showing the positions of the parts during insertion of connecting devices into one of the flanges of the bobbin and subsequent crimping of theferrule-forming portions of the connecting devices onto the coil tap wires. 1 a

FIG. 8 is a frontal view of abobbin jig on which a bobbin being processed in accordance with the invention is mounted.

.FIG. 9 is a sectional side view of the bobbin jig of FIG. 8 showing the positions of the parts at the time of insertion of connecting devices into the bobbin flange.

FIG. 10 is a view similar to FIG. 9 but showing the positions of the parts immediately prior to crimping of the connecting devices onto the tap wires from the coil.

FIGfll is a view taken along the lines 11-11 of FIG. 9.

FIG. 12 is a top plan view, with parts broken away, of the bobbin jig showing the positions of the parts at the beginning of the operating cycle.

FIGS. 13 and 14 are views similar to FIG. 11 but showing it at successive stages of the operating cycle.

FIG. 15 is a view taken along lines 15-15 ofFIG. 10.

Referring first to FIG. 2, an electrical coil 2 in accordance with the invention comprises a winding of relatively fine wire on a bobbin 4 having spool portion 6 which supports the winding and

flanges

8, 10 extending from the ends of the spool. The flange 10 has a relatively thick cross section on one side thereof as shown at 12 which is provided with openings 36 in which connecting devices 14 are received.

The connecting devices are advantageously manufactured in the form of a continuous strip 15, each device comprising a mounting arm 16 having serrated edges, a terminal portion in the form of a laterally extending tab 18, and a ferrule-forming portion 20 which is in axial alignment with the mounting arm 16. This ferrule-forming portion is adapted to be crimped onto one of the tap wires 34, 34' of the winding end and may be provided with insulation piercing grooves in accordance with US. Pat. Nos. 2,800,638 and 3,1 1 1,554. The conductors commonly used for coils are usually provided with a thin film of varnish-type insulation such as polyvinyl formal resin which is commercially available under the trademark Formvar. The

provision of insulation piercing means in the ferrule-forming tap wires are disposed above the ferrule-forming portions of the connecting devices. These ferrule-forming

portions

20, 20 are supported on

anvils

28, 28 so that as a die-plate 32 moves downwardly towards the anvils, the forming surfaces 30, 30' of the die plate will crimp the ferrule-forming portions of connecting devices onto the wires. After completion of the crimping operation, the connecting devices will extend outwardly in the plane defined by the flange section 12 and it is desirable to bend the connecting devices inwardly so that their tap portions 18, 18' are disposed in spaced relationship to the surface of the coil as shown in FIG. 2. This may be done by hand or by a suitable bending jig. When external connections are to be made to the coil, it is merely necessary to engage complementary receptacle type terminals with the tabs I8, 18'.

A complete apparatus in accordance with the invention (FIG. 1) comprises a connecting device inserting means 40, and a bobbin jig 42 which are mounted on a common baseplate 44 which in turn is mounted on the platen 46 of a suitable press 48. The press may be of any desired type, for example, as shown in US. Pat. No. 3,046,636. The inserter 40 and the jig 42 are located beneath, and on opposite sides of, the press ram 50 to which the previously identified die-plate 32 is secured as shown.

The inserter 40 in the disclosed embodiment is of the type fully described in application ser. No. 6,103 filed Jan. 27, 1970, so that only a brief description of its operation is required for purposes of the instant disclosure. Inserters of this type comprise a horizontally reciprocable slide member 52 (FIG. 9) having a feed track plate 53 secured to its upper surface in which are provided tracks for feeding the strips I5, 15' of connecting devices. The slide 52 is mounted on stationary frame means generally indicated at 54 which is supported on the common baseplate 44. Reciprocation of the slide is effected by a piston cylinder 56 mounted beneath the frame portion 54 and a vertically reciprocable faceplate 58 is mounted on the front of the apparatus which incorporates shearing means to shear the leading connecting devices 14, 14' from the strips. Subsequent to shearing of these connecting devices, they are gripped by spring-biased gripping fingers 62 mounted on a mounting block 60 on the top of the plate 58 and held as shown in FIG. 9 while the slide moves towards the bobbin jig to insert the mounting portions 16, 16' of the connecting devices into the flange 12 of the bobbin mounted on the holder portion 22 of the jig.

The piston rod of the piston cylinder 56 is connected to a laterally extending block 66 which in turn has a pivotal connection to a connecting rod which extends towards the jig 42.

This connecting rod actuates the jig in a manner which will be described below to bring about the movement of the arms 24, 24' and the movement of the holder 22 relatively towards and away from the inserter during the operating cycle.

The bobbin jig 42 comprises

fixed frame blocks

70, 74 which are mounted in spaced-apart relationship on the upper surface of plate 44 and which are separated by

spacer blocks

73, 74 to which they are secured, Recesses 76, 78 (FIG. 11) are provided on the opposed sides of the

blocks

70, 74 at the upper ends thereof for the accommodation of a reciprocable main slide 80,

retainer plates

81, 81 being mounted on the upper surfaces of the fixed blocks and extending over edge portions of the slide to retain the slide as shown in FIG. 11. The previously identified anvils 28, 28' extend from an anvil plate 82 which is secured by fasteners 83 in a suitable recess in a faceplate 84 which is, in turn, secured by fasteners to the ends of the

fixed blocks

70, 74.

Main slide 80 is reciprocated by a toggle

mechanism comprising links

88, 90, the link 88 being pivotally mounted at the left-hand end of the slide in a recess 92 on the underside of the slide. The link 90 has a pivotal mounting 96 on the previously identified spacer block 73 and the two links have interfitting ends which are pivoted on a common pivot pin 98. It will thus be apparent that when this toggle is broken as shown in FIG. the main slide will be in its retracted position and when the toggle is straightened, the slide will be moved to its forward position (FIG. 9).

The actuation for this toggle mechanism is provided by a lever 100 (FIG. 10) which is pivoted at its left-hand end 102 in a suitable recess in faceplate 84. Roller means 104 on the end of this lever are received in slots 106 provided in depending ears 108 on the link 90. Lever 100 is oscillated by means of a cam follower 110 on the end of a stub shaft 112 having a reduced end 114 which is mounted in the lever 100 intermediate its ends. Cam follower 110 is received in a confined cam track 116 of a cam block 118 which is slidably supported in a guide track 120 in block 74,

retainer plates

122, 124 being secured to the block and overlapping the camming block 118 as shown in FIG. 11. A connecting block 126, secured to the cam block 118 and extending laterally therefrom, has a pivotal connection 128 to the end of the previously identified connecting rod 68.

It will be apparent from a comparison of FIGS. 9 and 10 that when the cam block 118 moves rightwardly from the position of FIG. 10, by the connecting rod 68, the

toggle mechanism

88, 90 will be straightened and the main slide will be moved leftwardly; during reverse or leftward movement of the cam block, the toggle is broken and the main slide 80 is retracted.

The previously identified bobbin holder or spindle 22 is mounted on the horizontally extending arm portion 130 of an L-shaped bracket, the vertically extending arm 131 of which is secured by a fastener 134 to a vertically extending ear 132 on a secondary slide member 136. In order to firmly position the bobbin on the holder 22, it is desirable to provide a slot 19 in the bobbin and to mount a biasing plate 21 in this slot. It will be understood that this plate is outwardly biased by a spring and that when the bobbin is moved down onto the bobbin holder (FIG. 4), the plate will be resiliently moved into the slot. The plate, however, urges the bobbin rightwardly as viewed in FIG. 4 with respect to the bobbin holder so that the left-hand end of the bobbin, the side adjacent to the crimping die plate, will be accurately and precisely located.

As shown best in FIG. 11, a channel 138 is provided on the upper surface of a primary slide 80 for the accommodation of this secondary slide and suitable retainer plates or guide plates are secured to the main slide and extend over the surface of the secondary slide. Secondary slide 136 is biased leftwardly with respect to primary slide 80 by means of a spring 140 contained in a recess 142 which extends inwardly from the righthand end of the secondary slide. A plate 144 is secured to the primary slide and extends across this recess to retain the spring in position. It should be mentioned at this point that spring 140 will ordinarily bias the secondary slide leftwardly until the L-shaped bracket 131 moves against a mounting block 154, described below, which is secured to the left-hand end of the primary slide. When the primary slide moves leftwardly to the limit of its travel, FIG. 9, a stop screw 148, mounted in an ear extending upwardly from the secondary slide, moves against a transversely extending stop bar 146 so that the primary slide moves slightly beyond the secondary slide and a gap 149 is left between the block 154 and bracket 130. The stop bar 146 extends transversely over the upper surface of the secondary slide and has its ends secured to mounting

blocks

152, 152 which are secured to the previously identified retaining plates 81, 81' and the fixed frame blocks, 70, 74 as best shown in FIG. 11. When the parts are in the position of FIG. 9 it should be noted that the transversely extending retainer bar 144 is against the right-hand end of the secondary slide. When the primary slide is in its retracted position (FIG. 10) a slight gap 151 will exist between the surface of bar 144 and the right-hand end of the secondary slide. The function of the secondary slide, and the significance of its limited movement of the primary slide are described below in the description of the operation.

The wire-positioning anns 24, 24' are pivotally mounted on a common pivot pin 25 contained in the block 154 which is secured to the main slide so that this block will move with the slide as is apparent from FIGS. 9 and 10. These arms have

inner portions

23, 23 which are disposed beneath the bobbin holder 22 and have vertically extending transition sections 27, 27' intermediate their ends. The

end portions

29, 29 of the arms are directed inwardly, as best shown in FIG. 3, and the wire-receiving slots 26, 26' are provided in vertically extending ears on the ends of the arms. The arms are shaped such that the

slots

26, 26 will be disposed adjacent to the forming

surfaces

30, 30 of the die-plate 32 when the arms are swung inwardly as illustrated in FIGS. 4-7.

Arms

24, 24 are biased by springs 155, 155' in opposite directions to their outer positions (FIGS. 3 and 12). These springs have their inner ends secured to pins on the intermediate portions 23, 23' of the arms and have their other ends anchored to pins extending upwardly from the retainer plates 137, 137' and the primary slide 80.

The arms are swung inwardly from the positions of FIGS. 4 and 12 to thepositions of FIGS. 7 and 14 during rearward movement of the primary slide by latch arms 156, I56 disposed on each side of the central section of the primary slide and in recesses 157 and the undersides of the blocks I52, 152'. Latch arms 156, 156' are pivoted on

pins

158, 158 at the rearward ends of the blocks 152, 152' and are biased inwardly towards the primary slide by springs 159, 159' which are contained in holes in the blocks 152, 152' and which bear against the outwardly facing edges of the arms.

The opposed inner edges of the

latch arms

156, 156 have inwardly directed intermediate portions 160, 160' which are engaged by depending pins 170, in the wire-positioning arms. The inclined edge portions 160, 160' of the latch arms extend to forwardly facing shoulders 162, 162' which are adapted to receive the pins 170, 170' during forward movement of the main slide as will be described below. Forwardly of the

shoulders

160, 162, the arms again have opposed

convergent edges

164, 164 and the ends of the arms are provided with upstanding ears 166, 166'. As will be apparent from FIG. 8, these ears are so located that they are engaged by the comer portions 168, 168' of the die-plate 32 when the ram moves downwardly to its lowermost position.

The operation of the disclosed embodiment is as follows: the operator first positions a bobbin on the bobbin holder 22 of the bobbin jig as illustrated in FIGS. 3 and 4. He then actuates the apparatus by a suitable foot switch or other convenient switch to supply compressed air to the piston cylinder 54 and initiate the cycle. Initially, the insertion slide of the inserter 40 and the connecting rod 68 are moved rightwardly. During such rightward movement of the insertion slide 52, the leading connecting devices of the two strips of connecting devices are severed from the strips and carried to the position shown in FIG. 9. Concommitantly, the rightward movement of connecting rod 68 causes the cam 118 to be moved to the right-hand end of the bobbin jig. This causes the

toggle mechanism

90, 88 to be straightened with accompanying leftward movement of the main slide 80 of the bobbin jig so that the bobbin is moved relatively towards the inserter. During this portion of the cycle, that is while the inserter slide is moving rightwardly and the main slide 80 is moving leftwardly, the connecting devices are inserted into the openings in the flange portion 12 of the bobbin.

The instant of insertion is shown in FIG. 9 and as pointed out above, when the parts are in the positions of this Figure, the stop screw 1148 of the secondary slide is against the stop bar 146 and the retainer plate 144 is against the right-hand end of the secondary slide. The secondary slide is thus firmly held against any movement and the bobbin itself will thus be supported against right-hand movement so that it will not yield or retreat during the forcible insertion of the mounting portions l6, 116' of the connecting devices into the flange portion 12 of the bobbin.

During this first portion of the operating cycle, the pins 170' move along the convergent edges 160, 160' of the latch arms and bias the latch arms outwardly and at the conclusion of this portion of the cycle, the pins 170, 170' are lodged in front of the shoulders 162, 162' of the latch anns. The positioning arms remain in their swung out positions (FIG. 5) but are swung inwardly during subsequent retracting of the main slide as described below.

During the second portion of the operating cycle, the connecting rod 68 returns to its original position, that is, it moves leftwardly as viewed in FIG. I; and the

toggle

88, 90 is broken and the main slide 80 of the bobbin jig is moved rightwardly to the position of FIG. 10. During this rightward movement of the main slide, the pins 170, 170' are prevented from moving rightwardly by the shoulders 162, 162' so that the wire-positioning arms are caused to pivot about their pivotal axis as this axis moves rightwardly and their ends are swung inwardly to the positions of FIGS. 7 and 14. The inward swinging movement of these arms occurs during the rightward movement of the bobbin mounted on the bobbin holder 22 so that at the conclusion of the portion of the cycle the ferrule-forming portions of the connecting devices are supported on the upper surfaces of the anvils 28, 28' and the wires are located directly about these ferrule-forming portions. It should also be noted that at this stage of the operating cycle, the secondary slide 136 is at the limit of its limited leftward movement under the influence of the spring 140 and is against the side of the block 154.

The press 48 is then actuated to drive the ram 50 and the die-plate 32 downwardly to crimp the ferrule-forming portions of the terminals onto the tap wires. It is inevitable in a crimping operation of this type, that some extrusion of the metal will take place resulting in an elongation of the ferrule-forming portion. This elongation is accommodated by the clearance 15] between the right-hand end of the secondary slide 136 and the retainer plate 144 on the primary slide. In other words, the secondary slide will move rightwardly as viewed in FIG. 10 by a very slight amount when the ferrule are crimped onto the wires to accommodate the elongation of the ferrules which results from the crimping process.

When the die plate is lowered to the position of FIG. 7, the

corners

168, 168 of the die plate engage the ears 166, 166' on the ends of the latch arms and bias these ears outwardly until they move past the pins 170, 170'. The

springs

155, 155 then cause the wire-positioning

arms

24, 24 to be swung outwardly to the positions of FIG. 3. Upon ascent of the ram, the parts are returned to their original positions and the operator can remove the bobbin from the bobbin holder.

A terminated bobbin in accordance with the instant invention has the advantage of providing an integral terminal on the connecting devices to which its tap wires are connected so that when it is assembled to a further apparatus, the necessary connections to the coil on the bobbin can be made by merely engaging terminals on the apparatus with the terminal portions l8, 118' on the bobbin. Furthennore, the connecting devices in the bobbin and the electrical connection between these connecting devices and the tap wires are conveniently located in spaced relationship to the surface of the windings and between the bobbin flanges. This arrangement provides a maximum amount of protection for the connecting devices in the event that they should be carelessly handled or dropped.

The method and apparatus of the instant invention offer substantial advantages in that at least one, and possibly two soldering operations are avoided and are combined with what was previously a simple terminal inserting operation. The cycling time for the apparatus disclosed is not substantially greater than the cycling time for previously known machines for inserting terminals into bobbins. However, the previous practice in the art accomplished only the insertion or assembly of the terminals to the bobbins and the soldered electrical connections had to be made at a later time and in a separate manufacturing step. In accordance with the instant invention, the entire terminating and assembly operation is carried out in a single step.

Changes 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.
