The innovation relates to an anreihkleaae was attachment avf «la» r synaetrisehen or uhnyaaetrlsehen carrier rail, in which the individual attachments for the attached and outgoing Laltnag are designed as visual, plumbing or plug-in attachments «ad flable a fuse are electrically connected ·

Sole marriages of attachable security clusters are gassed into Switchgear, controls and devices that require Abelen - preparation of the main and / or tax circuit circuits. individual security sounds on mounting rails next to each other to them and to join together to Klesaenlaistan, biatat one of the legs considerable advantages such as easy changeability, good availability as well as a small need for space compared to the usual ones Installation agents

It is known to arrange a fuse link in an upwardly open recess in the insulating material housing of an anreihkleaae in such a way that the fuse link, inserted into a protective cap, can be inserted from above and via the screw thread of the connecting body sits the outgoing conductor and via the foot cycle of the other terminal body old dea ankoaaenden conductor is electrically connected · Bin from above inserted pairing at this object on the Fuflkontakt of Federeleaenten gahalta _"t so that only SieherungseinsStzot the dea PaBring are assigned, can be used · the disadvantage of this Ausführungsfora is Dafi of PaBring old a special connection through the screw thread from above into the recess of the stackable Sieharvagskleasio nut. This is not only very difficult with the schaal-built Sieheratg · - knees, it is also necessary · It is particularly difficult to replace such pair of inserts because they have to be screwed through the screw thread of the connection body for the outgoing conductor.

Furthermore, securing elements are known in which the fitting ring is provided with a threaded insert so that it enters the recess from above of the fuse element are used and in a corresponding The threaded hole of the foot contact can be screwed in · Also with this version · form is used to insert the fitting ring a special pair of pliers is required · The removal and replacement of the fitting ring for differently sized fuse inserts can also be carried out can only be done with these pliers

However, a modular terminal has also become known where the im Insulated housing directly above the base contact of the modular terminal a lateral recess is provided, which serves to accommodate an insulating part designed as a fitting, which is optional can be provided with a reducing ring · The disadvantage of this embodiment is that it is used to hold and guide the reducing ring an additional part in the form of a fitting piece must be made of insulating material, that is, there are increased Costs in the manufacture and assembly of such fitting inserts · Furthermore is in the operating state of the fuse a ventilation of the same or a direct dissipation of the heat from the insulating material housing not possible·

The innovation is based on the task of designing a stackable fuse terminal so that the required fitting ring for the various Fusible links of different amperage quickly, can be used easily and without the aid of tools, the accumulated heat in the area of the passport insert can be easily dissipated and that the production and assembly is reduced to a minimum of effort

This object is achieved according to the invention in that in the insulating housing A lateral recess is provided directly above the foot contact of the alignable fuse terminal, which is used for Receipt of a part designed as a fitting ring, which can be used in different sizes depending on the rated current of the fuse and is centered and held by a bracket

An exemplary embodiment of the innovation is shown in the drawing and is described in more detail below. It shows:

Fig. 1 the open, stackable fuse terminal with fuse link and the inventive arrangement of a fitting ring in view.

Fig. 2 is a side view of the closed securing clamp in partial section.

Fig. 3 shows the top view of the closed securing clamp.

4 shows the clamp for fastening the fitting ring within the insulating material housing.

The alignable safety clamp according to FIGS. 1 to 3 essentially consists from the two-shell insulating housing 1, which by means of Latching device 2 can be attached to a standard mounting rail 3 The inserted in the insulating housing contact parts 4, 5 for the lines supplied from the outside are via a fuse 6 and the Screw cap 7 electrically connected to one another. The screw cap 7 with fuse 6 is from above into a recess 8 of the insulating housing 1 inserted, the screw thread 9 via the contact part 5 »with the one connection body 15 and the foot contact 11 is connected to the other connection body 12 via the contact part 4. Bine provided above the foot contact 11 in the insulating housing 1 Recess 13 is used to receive and hold the inventive arrangement of the fitting ring l4. The fitting ring 14 is with a clamp l6 provided in corresponding recordings of the insulating housing 1 is held captive and the fitting ring 14 is fixed.

The terminal 15 is bent, for example, omega-shaped and comprises the Fitting ring 14. The captivity of the clamp 15 is achieved in that the bent ends 17 behind projections aes insulating material housing 1 grab.

The insertion of a fitting ring 14 is done in such a way that it is easy is pushed through the opening 13 in the insulating housing and is held by the clamp 15. On the opposite

Side of the recess 13 is a reduced recess l8 so arranged, that through them z. B. the fitting ring 14 can be removed through the recess 13 by means of a screwdriver.

The advantages achieved with the innovation relate in particular to a stackable fuse terminal with a fitting ring for receiving and Guide of the fuse link simply inserted and exchanged can be. Furthermore, the dissipation of heat generated is reliably guaranteed through the opening 13 and 18.
