专利摘要:
An electrical coil assembly comprises a rectangular, flat annular coil and a flexible annular covering of, for example, fibre board sheet surronding the coil so as to provide a substantially dustproof seal. The covering is formed by folding and glueing a blank around the coil. The blank comprises a rectangular annular portion a first pair of flaps extending one from each of two opposite outer peripheral sides of the annular portion, a second pair of flaps extending one from each of two opposite sides of the inner periphery of the annular portion and further flaps extending from the outer periphery of the annular portion. The annular portion is provided with fold lines and is of a size, when folded, to overlie opposite faces of the coil and the flaps fold around the inner and outer peripheries of the coil to provide a substantially dustproof seal.

(54) ELECTRIC COIL
one
The invention relates to electrical engineering and can be used, in particular, as an inductor of an automobile starting engine.
An electric coil is known, the outer insulation is made of insulating paper or fiberglass, wound around the coil C.
The disadvantage of this design is the high complexity of the manufacture of the insulating coating.
Closest to the invention in its technical essence and the effect achieved is an electric coil comprising a rectangular winding with a rectangular opening and outlets and an insulating coating of a flexible sheet containing the main rectangular part and folds with fold lines. The tails are located only on the outer surface of the insulation sheet 2.
The disadvantage of this coil is low reliability due to incomplete coverage of the coil surface with an insulating sheet.
The aim of the invention is to increase reliability and reduce labor intensity by insulating the entire surface of the coil with an insulating sheet.
To this end, in an electric coil containing a rectangular winding with a rectangular opening and outlets and an insulating coating of a flexible sheet containing the main rectangular part and folds with fold lines, an insulating sheet has a rectangular cut-out in the form of an aperture in the coil , on the smaller sides of the notch, there are made facies covering the inner surface of the smaller sides of the holes in the coil and part of the rear end surface of the coil, the front end surface, side surfaces and part of the rear surface of the coil yvayuts main part of the sheet, and upper and lower coil surface, large side opening in the coil coated tails,
20 located along the outer perimeter of the sheet, with the folds covering the adjacent surfaces of the coil overlapping each other. In FIG. 1 shows a coil without
25 isolation / general view; in fig. 2 - coil, rear view; in fig. 3 - the same, front view; in fig. 4 - insulation sheet.

The coil contains a winding 1 with terminals 2 and 3 and an insulating coating 4 in the form of a flexible sheet. The sheet contains a main rectangular part 5 and a rectangular notch b, as well as folds 7 on the sides of the sheet, separated from the main part by fold lines 8 parallel to the larger side 9 of the notch, folds 10 on the smaller sides of the notch, separated from the main part by folding lines 11, as well as additional tails 12-15 on the outer side of the main part of the sheet, separated from it by folding lines 16. The main part has additional vertical fold lines 17, and folds 7 and 10 additional fold lines 18-20, All bending lines of the insulating sheet are formed in advance by rolling, which facilitates the subsequent insulation of the coil by a sheet. The coil is insulated as follows. First bend upwards {relative to the plane of the drawing, fig. 4) Folds 7, 13 along fold lines 17,16, and fsds 15 are bent so that their rear sides adjoin the front sides of the tail 13. The winding 1 is placed in the half-current so that its hole coincides with the notch 6, and the tails 10 are bent upward along the fold lines 11. The width of each tail 10 is somewhat larger than the corresponding hole size. Then the bends 7 bend along the fold lines 8 and inserted into the winding hole and into the cut 6 of the sheet, and folds 10 are bent along the lines fold 19 so that the front side of the tail 10 is located above the corresponding folds 12. Nakhon The front ends of the tail 14 are glued to the rear sides 13, the areas of the tail 10 between the fold lines 20 and the ends of the tail 10 are also glued to the rear panels of the corresponding tail 13, and the free ends of the tail 17 are glued to the back side of the main tail The carbon part of the sheet. In addition, for the convenience of the isolation process, the winding itself can be curved along an arc so that the side shown in FIG. 2 was convex, and the side shown in FIG. 3, concave. If necessary, the coil after insulation can be treated by impregnation over the entire surface or only at the locations of the leads. The offered electrical coil has high adaptability and reliability. An electric coil comprising a rectangular winding with a rectangular opening and outlets and an insulating coating of a flexible sheet containing a main rectangular part and folds with fold lines, about 20 tons, and so that, in order to maintain reliability and reduce labor intensity due to insulating the entire surface of the coil with an insulating sheet; a rectangular cut is made in the insulating sheet according to the shape of the hole in the coil; on the smaller sides of the cut, tails are made covering the inner surface of smaller A coil hole and a portion of the coil back end surface, a front face surface, a side coil surface and a portion of the back surface of the coil are coated with the main part of the sheet, covering adjacent surfaces of the coil overlap.
