Definitions

  • the invention concerns an electric appliance switch comprising a fuse seat and specially provided for mounting on a bar.
  • the technical problem to be solved by the present invention is how to improve a fuse seat so that it will be able to be matched to fuses of various dimensions in a simple way, and how to insulate a down conductor contact, whereat a dropping of the fuses out of the seat should be made impossible and the down conductor contact should be protected against being touched.
  • the electric appliance switch comprising a fuse seat and characterized in that a wall of the seat surrounding the fuse is provided with a first and a second guiding slot being adjacent to each other at a first end of the seat, and with a third guiding slot at a second end of the seat, all said slots being transversal to the seat axis, and that in the first guiding slot there is engagably inserted an electrically conducting intermediate plate, which in a state of closed contacts through its cuff electrically contacts a down conductor contact, which is protected by an insulated partition all around except at the side of the cuff of the intermediate plate and in the second guiding slot a bow spring is engagably inserted and in the third guiding slot a size controlling bow insert is engagably inserted.
  • the electric appliance switch according to the invention is further characterized in that the intermediate plate is provided with feet pointing to the second end of the seat, and that the feet of the intermediate plate additionally fix the bow spring, whose both bow ends are elastically spreadable.
  • an improvement of a known fuse seat is accomplished by simple means; thus a simple replacement of the fuses of various dimensions is made possible and when the electric appliance switch is installed in a horizontal position, no dropping of the fuses out from a magazine in the seat happens.
  • the seat can remain in the electric appliance switch, however, switching on is only possible when the seat is inserted properly.
  • an insulating partition By an insulating partition a down conductor contact is completely protected against being touched.
  • Fig. 1 an improved fuse seat according to the invention in an electric appliance switch
  • Fig. 2 the electric appliance switch provided with the fuse seat as improved by the invention, in a state of open contacts and with the fuse seat and a size controlling bow insert being drawn out
  • Fig. 3 in a longitudinal section, the electric appliance switch provided with the fuse seat as improved by the invention, in a state of closed contacts.
  • An electric appliance switch 1 comprising a seat 10, provided with a magazine 20 for a fuse 11, is represented in a state of open and closed contacts in Figs. 2 and 3, respectively, the actual seat 10 for the fuse 11, however, is shown in Fig. 1.
  • the wall of the seat 10 surrounding the fuse 11 is provided with a first and a second guiding slots 31, 30 being adjacent to each other at a first end of the seat 10 and with a third guiding slot 32 at a second end of the seat 10.
  • the slots 31, 30, 32 are transversal to the axis of the seat 10. In a state of closed contacts the first end of the seat 10 is situated next to a down conductor contact 14 and the second end of the seat 10 is situated next to an intermediate contact 12.
  • an electrically conducting intermediate plate 22 is engagably inserted in the first guiding slot 31, and a bow spring 21 is engagably inserted in the second guiding slot 30.
  • a size controlling bow insert 23 is engagably inserted in the third guiding slot 32.
  • the intermediate plate 22 In the state of closed contacts, the intermediate plate 22 through its cuff 22" electrically contacts the down conductor contact 14, which is, through an insulating partition 15, completely electrically insulated from the surroundings.
  • the insulating partition 15 is made in one piece together with the remaining housing of the electric switch 1.
  • the intermediate plate 22 also provides for an efficient thermal contact of the fuse 11 to the down conductor contact 14.
  • the intermediate plate 22 makes possible a precise positioning of the seat 10 of the invention in the electric appliance switch 1.
  • the fuse 11 electrically contacts an intermediate contact 12 at the one hand and the down conductor contact 14 at the other hand.
  • the intermediate plate 22 is provided with feet 22", preferably with two feet 22", pointing to the second end of the seat 10.
  • the feet 22" push the bow spring 21 against the wall of the seat 10. So by means of the intermediate plate 22 the bow spring 21, whereby the fuse 11 is fastened in the intended position, is additionally fixed and it is prevented from dropping out of the guiding slot 30.
  • the bow spring 21 is provided with bow ends 21' which are elastically spreadable and embrace the inserted fuse 11.
  • the dimension of the fuse 11 is limited by the size controlling bow insert 23. It can be replaced when the seat 10 for the fuse 11 is drawn out from the electric appliance switch 1. Hereto a special tool is applied whereby the size controlling bow insert 23 is compressed slightly and pulled out from the slot 32 in the magazine 20.
  • the fuse 11 is easily accessible and can be replaced by spreading out bow ends 21' of the bow spring 21. Just the elastic bow ends 21' make it possible that the electric appliance switch 1 can be used in a horizontal position. The handling of the seat 10, remaining all the time in the electric appliance switch 1, is not hindered. A hazard of touching parts conducting electric current by mistake is reduced. Thereafter the fuse 11 and/or the size controlling bow insert 23 can be replaced.
