, This invention relates to a method of wi'ndpractice in some instances to connect an uninsulated terminalor stranded leadin wire to the end of'the enamel insulated wire preliminary to starting the wind ng ofthe'coil.
The :t'ree end of the'le'addh wire is then inserted through anjaperture provided in one of the spool heads of the core and the portion of the lead extending from the inner face of the spoolhead is covered with'paper or other suitable insulating material, after which the windingof the .coil is continued in the usual manner. In practicing this method of winding electrical coils a very high degreeof-care and skill is required in the winding of the coil in order to eliminate the possibility of the first oneor two turns of enameled wire in, the first .two or three'layers from working their way downwardlyalong theinner side of'the spool head and coming into cont-act .with' the bare lead-in wire,
which condition may, in some instances, result inportions .of the insulating enamel becoming-removed from the enameled wire,
thus rendering it possible for one or more i3o' layers of the coil being shorted from the remander of the coil. i -The principal object of method of winding electrical coils w erein the possibility of deleterious short circuits due to the. above causes is eliminated. I
In order to attain this object, in accord .ance with the features of the invention, the
uninsulated terminal or lead-in wire is con-. ao nected to the enamel insulated winding material in theusual manner and then covered with paper or other suitable insulatingimaterial. Atthe starting of the winding operation, the first few turns of the insulated wire 415' are superimposed upon the terminal or lead-- in'wire adjacent the inner face of the spool head, after which the winding of the 601i.
this invention is. the provision of an improved and simplified "a coil which has been partially wound in accordance with the improved method;
ig. 2'is a fragmentary-longitudinal sec- ,tion of the coilshown in Fig; l;
Fig. 3 ,is an elevational view, partly in section, of a completed coil, and
Fig. 4 is a detail "view illustrating the method of insulating the lead-in wire prehmmary to starting the winding of the coil. Referringnow to the drawingin detail,
in which similar reference numerals refer to.
like parts throughout the several views, the. numeral 10 indicates a core, composed of magnetic material, .and having attached thereto at'each end a spool head ll-which may be of metal. The core 10 .is preferably insulated-by one or more vlayers of paperor other suitable insulating'material l2, and one or more insulating washers 13 are usually pi'ovided'on the inner faces of the spool heads Before starting the winding of the coil a suitable length of a bare stranded lead-in wire 14 is connected to the end of the enamel insulated winding wire 15, as best shown in Fig. I is an enlarged fragmentary View of Fig. 4'. The free end of the lead-in wire is then insertedthrou'gh anaperture provided 1n the spoolhead 11 adjacent to the core 10 and a strip of paper 16 (Fig. 4) for other suitable insulating material is wrapped around the portion of the lead-in wire extending from the inner face of the spool head. The paper insulated lead-in wire is then-wrapped around the. core 10 adjacent to the spool ead through which it enters the spool. Before starting the usualwinding of the coil several turns of the enamel'insulated I winding material arewrapped around the lead-in wire adjacent tothe, spool head;
through which the lead-in wire enters the spool, as best shown in Fig. 2. The winding ofthe coil is then continued in the usual manner., Sheets or'strips 17 of paper or other suitable insulating material may be inserted between each layer of wire as the coil is built up and the completed coil is usually provided with an outer covering 18 as shown in Fig. 3.
In the manufacture of electromagnetic coils in. accordance with the present-invention, the possibility of deleterious short circuits due to the enamel insulated wire im-. p'inging against and electrically contacting with the bare lead-in wire is practically elim-' ,inated. It for any cause one of the first few turnsof the enamel insulated wire comes in contact with the bare lead-in wire; it could only result in a comparatively short length of Moreover, the possibilityqof one or more layers of wire being shorted from the coil is eliminated. sinceithe enameled wire in the above applied layers is prevented from eon tacting with the lead-in wire due to the intermediate turns of enameledwire which have been 1 superimposed jupon the lead-in wire before starting the winding of the'coil. Thus it is apparent that bypracticing the present invention coils of uniform electrical characteristi'csinay be very-readily manufactured,
' it only being necessary to insure that approximatc y the required amount of winding material is used.- Furthermore,-the possibility ofcoilsma-nufacturedby this method becom ing unsuitable for use due to deleterious short circuits caused by th'ebare lead-inwire con- I layers of the insulated conducting material tacting with the enameled wire ofthe upper.
layers of the coil is eliminated. i
