Self, Burlington, N.C., assignor to Western Electric Company, incorporated, New York, N.Y., a corporation of New York Filed May 7, 1962, Ser. No. 193,018 8 Claims. (Cl. 29-203) This invention relates to an apparatus for connecting Wire conductors to terminals and more particularly to an apparatus for wrapping onto a group of terminals secured to a circuit panel a plurality of lead wires secured to a group of components wherein the panel is selectively moved during wrapping to permit single layers of wires to be wrapped onto the terminals.
In the manufacture of circuit assemblies, it is necessary to connect circuit components, such as transistors, resistors, etc, to terminals projecting from circuit panels. More particularly, it is sometimes necessary to electrically and mechanically connect large numbers of circuit components to groups of terminals by wrapping lead wires extending from the components onto the terminals.
Known apparatus developed for wrapping lead wires onto terminals may include a housing and a wrapping bit mounted for rotation in the housing. A concentric recess may be provided on one end of the bit for receiving the terminal. The bit also may be provided with a peripheral groove extending longitudinally from the end for guiding a lead wire to be wrapped. A sleeve mounted over the bit maintains the wire in the groove. In operation, the bit is rotated relative to the terminal, whereupon the wire advances through the groove and is wrapped in a helical configuration on the terminal.
As the Wire is wrapped, the operator must carefully regulate the back feed, or back off of the wrapping bit relative to the terminal by maintaining the pitch of the helices uniform to effect a tight and satisfactory wrapped connection.
Close investigation of such known wrapping apparatus indicates that the limitations inherent in manually-controlled operations are eliminated by the provision of apparatus for mechanically controlling the back-feed of the terminals relative to the bits according to the speed of rotation of the wrapping bit.
An object of the invention resides in the provision of a new and improved apparatus for connecting wire conductors to terminals.
Another object of this invention is to provide in conjunction with an apparatus for wrapping wire on terminals, facilities for regulating the back-feed between the wrapping apparatus and the terminals according to the operation of the wrapping apparatus.
Still another object of this invention resides in the provision of facilities operated by a wire wrapping instrumentality for moving a clamping device to permit terminal posts secured to a clamped panel to advance through a predetermined distance for receiving a single layer of wrapped Wire.
A further object of this invention is to provide an in strumentality for clamping a terminal panel with the terminals positioned to receive helical convolutions of wire from a Wire iwrapping facility in conjunction with a mechanism actuated by the wrapping facility for releasing the clamping instrumentality according to the desired pitch of the helical convolutions.
With these and other objects in view, the present invention contemplates an apparatus for uniformly wrapping component lead wires onto terminals secured to a circuit panel. A holder is provided for clamping the panel with the terminals extending into recesses formed in a group of wire wrapping bits. A group of components is mounted on the bits so that component lead wires extend into peripheral grooves provided in the Wire wrapping bits. The bits are rotated simultaneously for Wrapping each lead Wire on a terminal. A mechanism is actuated simultaneously with operation of the bits for backing oif the holder. The holder permits the panel, and thus the terminals, to back-feed or backoif relative to the operating bits. The back-feed is regulated by the mechanism ac cording to the desired pitch of the helical convolutions for simultaneously wrapping uniform wire connections on the terminals.
A complete understanding of this invention may be had by reference to the following detailed description when read in conjunction with the accompanying drawings illustrating la preferred embodiment thereof, wherein:
PEG. 1 is a perspective view of a group of components having lead wires uniformly wrapped onto terminals provided on a circuit panel by an apparatus constructed according to the principles of the invention;
FIG. 2 is an enlarged perspective view of a holder for clamping the circuit panel with the terminals extending into recesses provided in a group of wire Wrapping bits;
FIG. 3 is a cross-sectional elevational view showing a drive mechanism for rotating the bits and for moving the holder during a wire wrapping operation; and
FIG. 4 is a view taken on line 4-4 of FIG. 3 showing a component having lead wires received in peripheral grooves provided in the wire winding bits.
Referring first to FIG. 1, a circuit assembly 1%} which may be manufactured according to the principles of this invention is shown including components 11 having lead wires 12 wrapped onto and forming wrapped or solder-less connections 14 with terminals 16 secured to and extending from a circuit mounting or panel 17 Referring generally to FIG. 2, an apparatus 18 for forming the solderless connections 14 is shown including a pair of spaced wire wrap bits 19 for each component 11 to be assembled. To form the solderless connections 14, the components 11 are positioned with a lead wire 12 extending into an eccentric slot 21 provided in each of the bits 19. The circuit panel 17 is then positioned so that a terminal 16 extends into a central recess 22 provided in each of the bits 19, and an arm 23 of a clamp mechanism 26 is secured for holding the terminals in the recesses. The 'wire wrap bits :19 are rotated whereupon helical convolutions of each lead wire 12 are Wrapped around the respective terminal 16 to form a solderless connection 14 between each lead wire 12 and each terminal 16. As successive convolutions 27 of each lead wire are Wrapped onto the respective terminals 16, the terminals are urged upwardly and advance out of the recesses 2.2. At the same time, the clamp mechanism 26 is actuated for moving the 23 upwardly. Upward movement of the arm 23 permits the terminals v16 and the panel 17 to move upwardly for precluding wrapping of overlapping convolutions of lead wire 12' on the terminals 16.
Referring in detail to FIG. 3, a base 23 is shown supporting a fluid motor 29 provided with a piston (not shown) and a piston rod 31. A bracket 3-3 connects this piston rod 3-1 to a slide 34 which is mounted for movement in a slot 36 provided in the base 28. A rack gear 35 is secured to the slide 34.
A group of plates 37 secured to the base 28 are provided with a series of bearing recesses 41 which are aligned with similar recesses 42 provided in an upper wall 43 of the slot 36. One of the wire wrap bits 19 is received in each series of bearing recesses 41 and 42. A pinion 46 is provided at one end 47 of each of the wire wrap bits 19 for engaging the teeth 49 of the rack gear 35 and rotating the bits 19. At the other end 51 of each of the Wire wrap bits 1?, the recess 22 is provided for receiving a terminal 16 extending from the circuit panel 17.
Also at the end 51, the slots 21 are machined longitudinally along the periphery of the bits 19 for receiving the lead wires 12 of the components 11. The walls 52 of the remsses 41 of an upper plate or common sleeve 53 surround each of the bits 19 for maintaining the lead wire 12 in each slot 21 Upon insertion of the lead wires 12 into the slots 21 and positioning of the panel 17 over the bits 19 so that the terminals 16 extend into the recesses 22, the arm 23 of the clamping mechanism 26 is locked for holding the panel 17 against the components 11. One end of the arm 23 is pivotally secured to a bar 56 that is provided with a threaded recess 57 and a slot 58 machined transversely to the recess 57. A screw shaft 59 is threaded into the recess 57 and locked against rotation therein by a pin 61 which is inserted in the slot 58 and a lock notch 62 formedin the shaft 59. The shaft 59 is threaded into a nut 63 that is maintained in a fixed axial position by the shoulder 64- of a counterbored aperture 66 provided in a lower plate 67 of the group of plates 37. A pinion gear 68 secured to the nut 63' meshes with the rack 34 for rotating the nuts 63 within the aperture 66.
The other end of the arm 23 may be locked to an elongated block 71 by a latch 72. The block 71 is similarly provided with a threaded recess 73 and a slot 74 for receiving a second screw shaft 76. A second pin 77 is inserted into the slot 74 and an aperture 78 provided in the shaft 76 for precluding relative rotative movement between the block 71 and the second shaft 7 6. The other end of the shaft 76 is threaded into a second nut 79 that is rotatably mounted in a counterbored aperture 81 provided in the lower plate 67 and precluded from axial movement by a shoulder 82 of the aperture 81. A pinion gear 83 secured to the nut 79 meshes with the rack gear 34 for rotating the nut 79.
In the operation of the apparatus, the components 11 are mounted on the bits 19 with the lead wires 12 inserted in predetermined slots 21 whereafter the circuit panel 17 is placed over the wrapping bits and the terminals 16 inserted into preselected recesses 22 of the wrapping bits 19. The arm 23 of the clamp mechanism 26 is rotated toward the block 71 and is secured by the latch 72 for maintaining the panel 17 against the mounted components 11. A valve 84 is then operated for supplying pressurized fluid to the fluid motor 29. The motor 29 advances the piston rod 31 and the bracket 33 to the left for advancing movement of the bits 19, the bits are precluded from ad vancing relative to the terminals 16.
The clamp mechanism 26 is operated as the bits 19 rotate for releasing the panel 17 so that the force between the bits 19 and the wrapped convolutions is efiective to advance the terminals 16 upwardly out of the recesses 22. The clamp mechanism 26 is operated upon advancement of the rack gear 35 to the left. The rack gear 35 rotates the pinions 68 and 83 which rotates the nuts 63 and 79. Inasmuch as the nuts 63 and 79 are maintained in a fixed axial position by the shoulders 64 and 82 and the pins 53 and 77 preclude rotation of the shafits 59 and 76, the shafts 59 and 76 are advanced upwardly upon rotation of the nuts. The bar 56 and the block 71 are thereby advanced upwardly by the shafts 59 and 76 so that the arm 23 releases the panel 17 to permit the panel 17, and thus the terminals 16, to advance upwardly under the action of the back force during the wrapping operation. The speed of rotation of the wrapping bits 19 and the nuts 63 and 79, along with the pitch of the threads provided on the screw shafts 59 and 76 and the nuts, are
correlated so that the vertical advancement of the clamp mechanism 26 for each revolution of the bits 1 is equal nals 16 to form the solderless connections 14, the.opera-' tor opens the latch 72 and removes the circuit assembly 10 from the wrapping apparatus. then reversed to restore the bits 19 and the clamp mechanism 26 to their original position.
It is also contemplated that the circuit panel 17 may be secured to the arm 23 or to the bar 56 and the block 71. In this manner, the back-feed of the clamp mechanism 26 positively back-feeds the circuit panel 17, so that the terminals 16 receive uniform convolutions of lead wire 19.
It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
