Fuse disconnectors or fuse switch disconnectors

The innovation relates to a fuse disconnector or Fuse switch disconnectors with swivel-out fuses or separating tabs that can be opened by pivoting the cover be brought into or out of engagement with mating contacts located in the lower part, the pivot connection Formed between the cover and the lower part by pegs attached to the cover and recesses present in the lower part is.

Such fuse disconnectors or fuse switch disconnectors are known in various forms and designs. Included the pin on the lid is usually made flat

and can only rotate in the corresponding recess in the lower part if it is in the recess to the end is introduced because it is enlarged at the end. However, if pivoting of the cover is already attempted, if the pin has not yet been inserted into the recess to the end, it can easily be destroyed which either break off the pin or forcefully enlarge the recess

The innovation is based on the task of designing a fuse disconnector or fuse switch disconnector of the type described at the outset in such a way that an introduction and Pivoting the cover is possible without difficulty and the disadvantage described above does not occur. According to the innovation, there are two pins and on the cover Provided on the lower part in each case two depressions or recesses, one of which is a pin and a depression for Storage and the other pin and the other recess is used for guidance. Panning is only possible when the lid is inserted with its pin up to the end in the recesses. According to another feature of the The innovation can be offset on the housing in such a way that there is a stop for the in the open position Lid results, so that an open position alone through the swivel mechanism is made possible «To facilitate the attachment of the cover, the depressions or recesses are expediently with a funnel-shaped Enema provided. The walls of the lower part are at the locations with recesses and depressions expediently reinforced, but overall it is possible to provide smooth side walls for the lower part. The one on that Pins located on the cover can be made of molded material and be pressed onto the cover. However, it is too possible to attach metal approaches to the cover, which have the corresponding pins or z. B. by a draft are made.

In the following, reference is made to the drawing, in which an embodiment of the innovation is shown. the

1, 2 and 3 show the circuit breaker or the lower part in a side view, FIG. 1 being the closed one Position and Fig. 2 shows the open position. In Fig. 4, the lower part is shown in plan view.

In the drawing, 1 denotes the lower part of the circuit breaker, while 2 is the pivoting upper part, on which an operating handle 3 (Fig. 1) is attached to the outside and a fuse k (Fig. 2) is attached to the inside. As can ^be seen especially from FIG. 3, two grooves or recesses 5 and 6 are provided on the sides of the lower part, respectively. The depressions or recesses can be funnel-shaped. Have enema. On the cover 2 7 pins 8 and 9 are attached via an approach, which are inserted into the recesses 5 and 6. In the position shown in FIG. 2, the pin 9 is inserted into the recess 6 up to the lower end. In this position, the pin 8 rests against a stop 10 in the recess 5 and an open position is thereby achieved as shown in FIG a perfect swivel movement is guaranteed. The fuse 4, or possibly another connecting strap, then comes into contact with the mating contacts located in the lower housing part 1 and the switch is closed. The approach 7 and the pins 8 and 9 can consist of the same molding material as the cover 2 and be pointed at this with. However, it is also possible that the projection 7 consists of metal and the pins 8 and 9 are attached as passages. As can be seen from Fig. K , the walls of the lower part are reinforced at the points where the recesses 5 and 6 are made. The reinforcement is placed on the inside and so a design of the device with smooth outer walls can be produced, which is advantageous in terms of manufacturing.
