Abstract

The invention relates to the conversion of electrical energy and can be used to manufacture inductive coils. The purpose of the invention is to reduce the labor intensity and improve the manufacturability of the device. The device is made of a flat insulated conductor, consisting of longitudinal forming 1 with cuts 2 and transverse forming. Longitudinal forming 1 at least two times thinner than the transverse forming 3, and these thinning are located on different sides of the workpiece. Due to the fact that the longitudinal generators along the entire length are thinner than the transverse ones, the device is more technological and less laborious. 2 hp f-ly, 3 ill.

The invention relates to the field of electrical energy conversion and can be used in electrical engineering for the manufacture of inductive elements, in particular transformers, chokes, electromagnetic relays, etc.

The purpose of the invention is to reduce the labor intensity and improve manufacturability.

Fig. 1 shows the flat conductor of the inventive coil in Fig. 2 - a flat conductor consisting of two identical parts in the form of combined dies} in Fig. 3 — the proposed induction coil, axonometrics.

The induction coil is made of a flat insulated conductor consisting of longitudinal forming 1, with cuts 2 and transverse forming 3. Longitudinal forming 1 is at least two times thinner than transverse forming 3, and the thinning is located on different sides of the workpiece. generatrix - from the observer, and at the top - from the reverse side. The coil blank is made from a strip material or sheet of the required thickness by stamping or cutting. Thinning (longitudinal sections 1 can be done by milling or other known methods of machining metals.

The preform thus prepared is bent along a transverse line extending along an adjacent transverse generatrix so that when the preform is folded into an accordion, the longitudinal portions 1, bounded between two adjacent cuts 2, come in contact along the inner plane from the thinning side to form a two-layer longitudinal sections of coils (fig.Z). Due to the fact that the longitudinal forming 1 have a thickness that is two times smaller than the thickness of the transverse forming 3, when the blank is folded into the harmonica, the coil turns are the same thickness around the perimeter, which reduces the height of the coil by half. Moreover, one half of the billet

the height (thickness) maintains the continuity of the conductor without any joints, which improves the electrical and mechanical properties of the coil. When the preform is folded into an accordion to form flat coil turns (Fig. 3), the beginning of the coil is formed from elongated transverse 3 forming for output, the upper and lower longitudinal sections are formed during the folding of longitudinal thin sections 1 along the adjacent transverse 3 (the bending and folding lines are shown by dashed lines). As a result, the coil turns have the same thickness around the perimeter.

Flat insulated conductor can be made of two identical parts in the form of combs, combined counter with its teeth.

The offered coil is more technological and less labor-consuming, since the longitudinal forming along the entire length is thinner than the transverse ones.

Claims (3)
