  • the distributor accordingto the present invention mainly comprises a distributor housing formed with 1an opening, interruptor means turnably carried by the housing, a plug and socket type connection means having yat least two separable parts, one of which extends with a portion thereof through the opening to the exterior of the housing, first flexible conduct-or means inside the housing and connected at one end thereof to the interruptor means and at the other end -thereof to the other part of the plug and socket type connector means, a capacitor located outside the housing, a bracket xed to the housing iat the exterior thereof carrying the capacitor, in which the portion of the one part of the connector means is constructed and arranged to engage the bracket so that said one part is removably carried by the bracket, and at least one flexible branch con- -ductor means connected ⁇ at one end thereof to Ithe-one part of the connector means and at the other end thereof to the capacitor.
  • the distributor includes Ialso a second flexible branch conductor means connected at one end thereof to the one part of the connector ⁇ means and adapted to 'be connected at the other end thereof to a source of primary current.
  • the one -of the connector means preferably comprises an insulating body and a metal bar carried by the insulating body and having at least one free end in the rform of a prong projecting beyond the body into the interior of the housing and the other part of the connector means is in the form of a socket removably engaging the prong to be mechanically and electrically connected thereto.
  • the insulating body has preferably an inner portion extending through the opening in the housing and having a cross section substantially equal to that of the opening, and an outer portion located at the exterior of the housing which is formed with a pair of substantially parallel grooves respectively extending from opposite faces of the outer portion of the body into the latter, and the bracket has preferably a projection formed with a cutout open at one end in which the o-uter portion of the body is located with portions of the projection of the bracket to opposite sides of the cutout respectively 1ocated in the grooves.
  • bracket which carries the capacitor at the exterior of the housing is secured by the one part of the connector means against tilting and twisting even if the means which fasten the bracket t-o the housing should become loosened due to the vibrations the housing and bracket are subjected to.
  • FIG. 1 is 'a partially sectioned side view of the distribut-or arrangement according to the present invention
  • FIG. 2 is a partial .perspective view of an arrangement differing slightly from that shown in FIG. 1.
  • the distributor housing even ifthe means for holding the bracket'on the rientratav according to the present invention mainly comprises a distributor housing in which an interruptor means 17 is turnably mounted.
  • the housing is formed with an opening therethrough and a plug and socket type connection means 11 is provided which has at least two separable parts, one of which extends with a portion thereof through the opening in the housing to the exterior thereof.
  • a plug and socket type connection means 11 which has at least two separable parts, one of which extends with a portion thereof through the opening in the housing to the exterior thereof.
  • the connector means 11 actually has three separable parts and the part extending through the opening of the housing includes an insulating body 12 which carries a metal bar 13 extending through the insulating body 12 and having t-wo free end portions in the form of prongs 14 and 14 projecting inclined to the remainder of the bar 13 beyond opposite ends of the body 12.
  • the other two separable parts of the three part plug and socket type connector means in the embodiment shown in FIG. 1, comprises sockets 15 and 15 adapted to removably engage the prongs 14 and 14', respectively, to be mechanically and electrically connected thereto.
  • a flexible conductor 16 connects the socket 15 with the interruptor means 17, whereas a flexible branch to conductor 18 -is connected to the socket 15' at one end, whereas the other end thereof is Iadapted to be connected to the primary windin-g of an ignition coil.
  • the distributor includes further a capacitor 19 which is fastened, for instance by spot welding, to a bracket 20 which in turn is fastened by a screw 21 to the outer surface of the housing 10. 'Ilhe capacitor 19 is connected in parallel to the interruptor 17 by means of 'a flexible branch conductor 23 the end 22 of which is connected, for instance by soldering, to the metal bar 13 of the connector 11.
  • the connector means 11 has three separable parts
  • the part of the connector means 11 which is adapted to extend through the opening in the housing, not shown in FIG. 2 has a metal bar 13 which has only one free end 24 in the form of a prong projecting beyond one end of the insulating body 12 and adapted to 'be connected to the socket 15 at the end ofthe flexible conductor 16, while the flexible branch conductor 18 as well as the branch conductor 23 are xedly connected, for instance by soldering, to the other end of the bar 13' and the insulating body 12 surrounds the ends of the flexible conductors 18 and 23 which are 'allxed to the bar 13.
  • the insulating body 12 insulates the metal bar 13, or 13r from the housing 10 and in the arrangement shown in FIG. 2 the insulating body protects also the ends of the flexible conductors 18 and 23- from damage or dirt.
  • the bracket 20 is provided with an upwardly extending projection I25 formed with a rectangular cutout 26 open at the top and the insulating body 12 has an inner portion of a cross section substantially equal to that of the opening formed in the housing and an outer portion formed with a pair of substantially parallel grooves 27 which respectively extend from opposite faces of the outer portion of the body 12 into the latter.
  • the p0rtion of the insulating body 12 between the grooves 27 may be inserted into the cutout 26 so that the portions of the projection 25 on opposite sides of the cutout 26 are respectively located in the grooves 27 with the side faces of the cutout snugly engaging the bott-om faces of the grooves 27, respectively.
  • the bracket 20y of the capacitor 19 is thereby secured a-gainst tilting or twisting by enga-gement with the ⁇ insulating body 12 of the connector means 11 even though the bracket 20 is only secured by a single screw 21 to the housing 10.
