(54) ELECTRIC WINDOW

The invention relates to the technology of the fabrication of electrochemical devices and can be used in the manufacture of switching devices used in automation, telephony, information and measuring and switching technology.

The electrical winding is known, made in the form of a flexible two-sided printed circuit board, bent in the form of an accordion.

However, in the known electrical winding, closure of the windings is not uncommon.

In order to prevent clamping of the winding turns, the bends are filled with W-shaped ones.

FIG. 1 shows a ribbon with the simplest pattern of printed conductors; in fig. 2 the process of folding the tape shown in FIG. 1, in the package; n FIG. 3 - a ribbon with a pattern of printed conductors providing the maximum filling factor of the winding with an electrically conductive material; in fig. 4- folding process; the clips shown in FIG. 3, and the bag,

In accordance with the proposed invention, in order to print the winding on the surface of the tape 1 of flexible foil dielectric, two-sided printing of conductors 2, 3 is performed

with a pattern in the form of antiphase, periodic curves. The axis of symmetry of the figures is depicted by a dash-dotted line 0-0. The bends 4, 5, b of the tape 1 are made at a right angle of 180 ° with an alternating sign change. In this case, there are lines of separation bends 4, bite 1, separating the half-waves of the pattern oscillations (passing through the intersection points of the periodic curve 2, 3 with the axis of symmetry 0-0), and the line of technological bends 5, located on both sides of the separation lines bends 4 and a distance less than half the half-wave of the pattern. This ensures that the printed conductors 2, 3, t, e are not intersected, and that the winding turns out to be disconnected when the tape 1 is wrapped in a bag. The holes 7 designed to install the reed switch can be lolieni in various ways or they are performed in all the gaps between the dividing lines of the bends 4, b and arranged so that they are combined when folding the leg 1 into the bag, or execute them after the folding of the tape 1 per pack. To obtain a single winding, the ends of the conductors 2, 3 are connected by introducing an electrically conductive junction 8 from one printed conductor 2 to another 3. At the same time, the rocking of conductors 2 and 3

serve as the beginning of 9 and the end of 10 single o (coils. Obviously, the number of turns of the winding is equal to the number of half-waves of the pattern of printed conductors 2 or 3.

If the durations of all half-wave patterns of printed conductors are equal to each other (Fig. 1 and Fig. 2), when the tape 1 is folded into a bag, its adjacent segments, located inside the winding, are attributed from each other, on average, to the total thickness tapes 1 and printed conductors 2 and 3.

To increase the Cs, the period of the pattern of the printed conductors 2, 3 can be made up of two stucco oscillations consisting of half-waves, as shown in Fig. 3 and 4. At the same time, more prog swine in obo: the oscillations arrange one another, and the technological lines of the boom 5 have on both sides only those rafflRfi distant bends 4, which separate the UFYU long half-wave of the oscillations from the other.

which is much higher than in the previous version. In order to provide 1 maximum value of the filling factor of the winding with an electrically conductive material while maintaining the condition of non-intersection of the printed conductors, various forms of periodic curves can be utilized. The period of these curves, obviously, may consist of two and

more complete oscillations consisting of half-waves of various duration. But from the point of view of simplicity of the design, the most acceptable is the one of them, the period of which is minimal and i.e. consists of two vibrations.

In accordance with the invention, it is possible to carry out a group of non-intersecting windings simultaneously, in the form of a single package. Slaughter can be attributed to, for example,

oiCTeMia coordinate windings of the matrix switch on reed switches. In this case, in the form of one package, the following has been performed: t one coordinate group of windings spaced apart from each other at the required distance. Then, in a similar way, another coordinate group of windings is executed, after which one package is wrapped onto another, forming a coordinate winding in the form of a single, common package.
