Definitions

  • the invention relates to an ignition coil for internal combustion engines, in particular of motor vehicles, coil comprising a closed magnetic circuit around one of the branches of which are disposed a primary winding and a secondary winding housed in a box filled with an insulating material cast covering the base, with at least one high voltage output terminal held on the housing and comprising a metallic member connected by an electrical connection element, to one of the ends of the secondary winding, which high output terminal tension ensures the connection with the ignition distributor, via a conductive cable.
  • the Applicant has found that in such coils if the output terminal is crimped onto a thin insulating plate, snapped into the housing over small portions of its periphery, said thin plate deforms under the pressure of the electrical connection element produced in an elastic metallic material which ensures electrical contact, by pressing on the end of the metallic member housed in the high voltage output terminal.
  • the object of the present invention is to remedy this drawback by eliminating the thin plate on which the output terminal was fixed.
  • the invention relates to an ignition coil characterized in that the output terminal maintained on the housing, comprises a cam whose ramps, under the effect of a rotational movement imparted to said terminal, exert a pressure, of maintenance, on protuberances formed inside the case.
  • the advantage obtained by this invention consists essentially in that the output terminal being firmly held in its desired position on the housing, the defect in appearance of the ignition coils is eliminated in a safe manner and the manufacturing scrap for this defect , are thus deleted.
  • the ignition coil shown in FIGS. 1 and 2 comprises a closed magnetic circuit 1 consisting, in this embodiment of sheets cut and stacked one on the other.
  • Part of the sheets 1a is cut in a known manner, so as to form a circuit with three branches, the other part 16 closes the magnetic circuit in which a gap 2 is provided.
  • a primary winding 3 wound on a support 4 and a secondary winding 5 wound on a support 6 are housed in a plastic casing 7, then filled with an insulating material 8, cast covering the base of a high voltage output terminal 9 held on the housing 7.
  • the high voltage output terminal 9 made of insulating material is provided with a metallic member 10 which serves to establish a connection, by cable, between the ignition distributor (not shown) and the end 5a of the secondary winding 5 by by means of a connecting element 11 constituted by a thin strip of elastic metallic material ensuring electrical contact, by pressure on the end 10a of the member 10.
  • the primary winding 3 and the secondary winding 5 are connected by one of their ends to a terminal 12 supplying from the on-board battery of the vehicle (not shown), the primary winding 3 being connected, by its other end, to a terminal 13 ensuring the connection with a mechanical or electrical breaker (not shown).
  • the high-voltage output terminal 9 comprises a cam 14 (see fig. 2 and 3), the three ramps (15) of which under the effect of a rotational movement imparted to said terminal, in
  • the high voltage output terminal 9 is thus immobilized by pressure on the housing 7, in its desired position we can then proceed to the casting operation of the insulating material 8 after which the housing 7 is slid onto the central branch of the sheets the (see FIG. 1) the sheets 1a and 1b then being secured by means of metal plates 17 and rivets 18.
