Definitions

  • the invention relates to a double-shell housing made of insulating material for single or double-pole contactors with double interruption, in which in the working position the contact pressure is applied by contact pressure springs acting on the contact bridges and the attracted armature tensions a return spring which is stronger than the contact pressure springs.
  • the requirements of the housings of electrical contactors are generally that they enable the contactors to be manufactured easily and quickly and, in the event of a malfunction, that the cause be identified and rectified quickly and easily.
  • the latter applies in particular when the contactors in devices such as. B. electrically powered trackless vehicles or electric vehicles are installed, in which regular maintenance by appropriately trained personnel is not always given or possible.
  • the invention is therefore based on the object of specifying a housing for a contactor of the type described in the introduction, which allows easy and quick production, checking and repair of the contactor.
  • the solution according to the invention is that the elements of the magnetic drive and the movable contacts and the return spring are accommodated in a first shell with corresponding recesses, while the fixed contacts and both shells are accommodated in a second shell are interconnected.
  • the yoke is U-shaped and rests with its legs on the bottom of the first shell. It clamps the coil body with winding and core between its inner U-bottom and an eye formed on the bottom of the first shell, the length of which corresponds to the armature stroke.
  • the yoke, the core and the eye are provided with aligned bores through which screw connections run, the armature is provided with a recess which is concentric with the bores mentioned and permits free play of the armature around the eye, and it has actuating tabs for holding the Contact bridge in the rest position.
  • the return spring is prestressed against the shell by a holder passing through the first shell and a split pin fixing the holder on the outside of the shell.
  • FIGS. 1-10 show, in a partially schematic representation, an exemplary embodiment of a housing according to the teaching of the invention.
  • the first shell of a housing is designated 1. It accommodates a two-pole contactor with double break, whose U-shaped yoke is labeled 2, and a single-pole contactor with double break, whose U-shaped yoke is labeled 3.
  • the hatched area is not surmounted by any component shown in the shell 1 and is used for contact with the underside of the second shell, which is explained in an example with FIG. 2.
  • the screw 9 passes through, as shown in FIG. 3, the yoke 2 and engages in the core 6 located in the coil former 5 '.
  • the core 6 is braced against the bottom 7 of the shell by means of a further screw which is guided through the eye 8.
  • the anchor 10 has 8 free play around the eye.
  • the components are held under the yoke 4 by the screw 11.
  • the armature 10 of the two-pole contactor carries the two actuating tabs 12.
  • the actuating tab 12 keeps the cranked contact bridge 16 open against the contact pressure springs 14 under the action of the return spring in the idle state. Only when the magnetic drive is energized does the actuating tab 12 lift off, and the contact bridge 1C arrives at the fixed contacts assigned to it 15 under the action of the contact pressure springs 14 to the system.
  • the fixed contacts 15 are, as shown in Fig. 2, attached to the inside of the second shell and provided on the outside with connection options.
  • the fixed contacts 15 lie in the axis of the recesses 17 (FIG. 4) which receive the contact pressure springs 14 and approximately in the position shown in FIG. 4.
  • the function of the return springs is explained with reference to FIGS. 1 and 5.
  • the armature 10 carries two supports 18 for the return springs 19. In the position shown in FIG. 5, the armature 10 is shown in the working position, with the supports 18 tensioning the return springs 19 with respect to the guide body 20 and the cotter pin 21 against the housing 1 .
  • the unipolar contactor behaves correspondingly, the armature of which has the actuating flap 22 and the supports 23 for the return spring 24.
  • the contact bridge bears the designation 25 and works together with the fixed contacts 26 from FIG. 2.
  • recesses for blow magnets are present in the first shell on both sides of the interruption points. These recesses are designated 27 in FIG. 1. Furthermore, there are further recesses in both shells, which complement one another to form arcing chambers in the case of interconnected shells. The associated recesses are provided with the numbers 28 to 33 in FIGS. 1 and 2, the recesses with the same numbers uniting to form an arc quenching chamber when the shells are assembled.
  • openings are provided in the first shell, which can be closed by sliding panels that can be actuated from the outside. With them it is possible e.g. B. to observe the contact state.
  • the two shells of the housing are detachably connected to one another by screws or clips.
  • the housing according to the invention can be designed freely to accommodate one or more single or double pole contactors.
