The invention relates to electrical equipment of automobiles and can be used in the spark ignition system of internal combustion engines. A known ignition coil is provided with a hole or a channel in the cap, which is covered by a safety element, which, when the ignition catupps are heated excessively, prevents the coils from exploding by depressurizing the internal OZ volume. The disadvantage of such an ignition coil is the greater complexity of manufacturing the safety element compared to conventional ignition coils. In addition, after the safety element has triggered, it is difficult to reuse the coil, the ignition associated with the need to install a new set of safety element. A known coil comprising a hollow body of a cylindrical shape, closed at one end with a solid bottom and a flange on the other hand, an electrical insulating cover with a high voltage terminal, a sealing gasket, a sleeve covering 1 flange and an electrical insulating cover, primary and secondary windings with terminals, magnetic core and anti-explosive hole. In this coil, when the pressure exceeds a predetermined value, an anti-explosion device is triggered. At the same time, as a result of depressurization, the pressure decreases, not reaching dangerous limits, exceeding which can lead to an explosion of the coil body 2J. The disadvantages of the known construction are the impossibility of its repair due to the destruction of the body and the ejection of a sealing gasket in the area of the hole in the body. In order to restore its initial state, it is necessary to flare the whole body at the location of the installation of the PROCEDURE, which practically makes it impossible to use the damaged body for the second time. When repairing such a catupps, ignition is necessary. replacing the housing with corresponding costs associated with the laboriousness of manufacturing the housing and the consumption of material. The aim of the invention is to improve maintainability By reusing all parts of the ignition coil during repairs in reassembly. The goal is achieved by the fact that in the ignition coil for a spark ignition system of an internal combustion engine containing a hollow cylindrical body, closed at one end with a solid bottom and a flammable element on the other hand, an electrical insulation cover with a high voltage terminal located between the housing flange and the cover sealing gasket, clip, cover housing flange and electrical insulating cover, primary and secondary windings with output terminals, magnetic conductor and explosion opening made in the cage against the surface of the sealing gasket, the -barrel is open in one place along its forming line. . Fig, 1 shows a coil assembly, a general view; FIG. 2 shows the holder of the ignition coil, the ignition cartridge comprises a hollow body G with a bottom 2 on one side and a flange 3 on the other, an electrically insulating cover 4, a sealing gasket.5, primary and secondary windings 6 and .7, magnetic circuit 8, anti-explosion the device 9, in the form of an open, at least in one place 10, the holder 11 with the shoulders 12 and 13, which enclose the body 3 of the frame 1 and the electrically insulated crown 4. The end part 1A of the typesetter whose strip 5 is seen in the open part 1 at 1 11, a hole in protivzvyryun ycTpioflcTBe is formed by the ends 15 of the holder 11 in its open position. The principle of operation of the ignition coil in the normal mode of operation of the internal combustion engine does not differ from the work of known structures. In emergency mode, the pressure inside the coil body increases significantly in comparison with the operating mode, which results in a hermetic sealing gasket in the open meseo of the holder and depressurization of the coil, B depending on the elastic properties of the gasket sealants, thermal

The processes in the ignition coil, the operating and emergency modes of the ignition coil are experimentally chosen for the size of the open part of the holder. In practice, this value can be equal to 8-12 mm.

The proposed structure is reliable in operation and does not require

its repair replacement of any parts.

The manufacture of the proposed ignition coils will ensure the repair of 5 coils in operation with a maximum secondary 1m using ignition coils and gives a significant economic effect.
