Definitions
- This invention relates to a form of a toroidal coil which is sutiable for use wit-h a taping machine as disclosed in the above-identified applications wherein a method of taping is utilized which allows the flexible insulating tape, to be wound on the coil and about its projecting terminal, to be in close proximity to the terminal for efliciently insulating the same.
- the terminal is provided with a pointed terminal to pierce the tape.
- the single figure of the drawing shows in perspective view a toroidal coil wound of a conducting strip to which the invention has been applied.
- the tape is cut away on one side of the coil to show the details of the coil interior.
- the coil C to which flexible cotton insulating strip 68 is to be applied, is wound from copper strip material 60, insulated by a paper strip 62 positioned between the turns of the coil.
- the inner terminal end 64 is bent upwardly and outwardly to overlie the main body of the coil, as shown, and is preferably insulated by a strip of paper 66 positioned between the overlying parts.
- the tip 64A of the terminal end is pointed to aid in piercing the flexible cotton insulating strip 68 when the tape is wound over it at 68A during the winding operation on the machine disclosed in the aboveidentified applications for patent.
- the flexible insulating tape 68 preferably of cotton braid material, although other insulating materials such as paper, plastic or the like may be used, is supplied in the form of large rolls or containers (not shown) to the taping machine which applies the tape in, an even overlapping layer on the sides of the toroidal coil C.
- the winding of the flexible tape 68 begins on the coil C behind the terminal 64 and continues in a clockwise direction around the sides of the coil C until the pointed terminal end 64A approaches the win-ding position, at which time suflicient tension is applied to the tape 68, so that the point end 64A of the terminal pierces the tape at 68A to provide insulation behind the terminal.
- the outer terminal end 60 of the coil C will, in the meantime, have been bent transversely to the inner terminal 64.
- the winding cycle ends wtih the cutting of the tape from the source.
- the freely extending end 68B beyond the terminal 64A, is then wrapped manually about the coil and the terminal.
- An insulated coil comprising a conducting strip having continuous, integral, terminal ends for connection to an electrical circuit, said terminals both extending from the coil at one side thereof, the inner terminal being bent to extend outwardly across the turns of the coil, the outer terminal extending parallel to said one coil side normal to the inner terminal, insulation between the turns of the coil and between the inner terminal end and the turns including the outer terminal, flexible tape insulation positioned about the coil sides terminating at a point adjacent the inner terminal, said tape insulation being positioned in overlapping layers on the coil, and a pointed tip on the inner terminal end piercing the tape to position the inner terminal in an aperture in the tape at a point where the tape extends across the inner terminal whereby the inner terminal is insulated by the tape.
