Definitions

the invention relates to an NH fuse switching device, consisting essentially of contact pairs for receiving NH fuse links, the at least one front side, of the switched-out pivotable in a reversing position by about 150-180 0 and thereby covering in open position, the access opening to the contact pairs Switch flap can be fixed.
a fuse switching device with the aforementioned features is known from DE-PS 1040 646. According to the exemplary embodiments described there, it is provided that the reversing swiveling movement of the switching flap is achieved by appropriate guidance either in two pairs of slots or by means of two pairs of levers.
the present invention is therefore based on the object of providing an NH switching device which can be produced in a simple manner and which has greater stability than the known switching device without the space requirement of the arrangement increasing.
This object is achieved according to the invention on a switching device of the type mentioned at the outset by two side walls which receive the contact pairs and the connecting conductors between them and are screwed at a distance from one another and which have slots or slots which run obliquely to the front plane and in which cams projecting laterally on the switching flap are slidably guided, and by two levers provided on the side of the switching flap, which are mounted on the side walls as well as on the switching flap in fulcrums.
the lever guide in combination with a slot or groove guide achieves a significant improvement in the switch flap suspension, in particular transverse forces which are exerted on the switch flap are absorbed by the slot or groove guide. Bends in the side levers and the resulting inaccurate guidance are therefore excluded.
Another advantage that can be achieved with the invention consists in a simplified manufacture of the switching device by eliminating a pair of levers.
the invention can be used advantageously, in particular, in a fuse switching device in the form of a three-pole, single-pole switchable NH fuse strip with contact pairs and associated switching flaps one above the other, the contact pairs and connecting conductors between the side walls accommodating them forming the base body of the fuse strip and each switching flap via a combined lever and Groove or slot guide is attached to the side walls.
the previously known switchable fuse strips with superimposed contact pairs have the disadvantage that the switch flap is relatively difficult to access below an adjacent switch flap that is in the off position, for example when the fuse strip is installed at a low height above the ground and from above must be operated so that the switching flaps of the known fuse strips have a swivel angle of 90 ° and project transversely from the strip in the off position. This disadvantage does not occur in the switching device according to the invention.
the grooves or slots in the side walls have locking points, preferably in the form of indentations, which enable each switching flap to assume at least one defined intermediate position between the on and off position.
This measure makes the connection points of the receptacle contacts easily accessible from the operating side for the purpose of establishing the connection to the busbars.
such locking points can also be formed at the end of the grooves, so that the switching flaps are fixed in their end position (switch-off position) without the need for special springs.
the side walls are drawn forward so far that each switching flap lies completely between the side walls in the switched-on position. This prevents protruding parts of the switching flap from protruding into the operating aisle, which is particularly advantageous in walk-in network stations with space-saving operating aisles.
the side walls have recesses and projections on the inner sides for receiving connecting conductors, fuse receiving contacts and protective hoods, and that the parts are fixed in position by screwing the side walls together.
the adjacent receptacle contacts of different phases of a fuse block are relatively close together due to the switching flaps being guided according to the invention can, it is further provided that the adjacent receptacle contacts associated with different phases are each covered by a common protective hood, which is produced as a one-piece molded part and is fixed in the side walls of the fuse strip.
a further simplification is that parts of the protective hood provided for two adjacent contacts are used for the top and bottom receiving contact of the fuse strip. This is possible because the protective hood produced as a one-piece molded part can be dismantled at a predetermined location, preferably along a predetermined breaking line, so that a part for covering the uppermost receptacle contact and a part for covering the lowest receptacle contact of the strip is to be used. As a result of this measure, only one casting mold or injection mold is advantageously required for producing the protective hoods for individually standing and adjacent receiving contacts.
the NH fuse block consists essentially of two side walls 1, 2 screwed together with spacers 3, 3 ', switching flaps 4, 4', 4 '', ladders 5, 6, 7 and inclined contact pairs 8 , 8th'.
the spacers 3 are provided at the ends with an internal thread into which the side walls 1, 2 penetrate screws.
the fuse receiving contacts 8 are connected to the rear side in the side walls 1, 2 sunk busbar connection conductors 11, while the contacts 8 'are connected to the risers 5, 6, 7.
the connection zone of the vertical ladder is shielded when a plurality of fuse strips are mounted next to one another by a laterally inserted insulating piece 12 to the adjacent strip.
the vertical ladders 5, 6 resting on the side walls each have a bore into which a projection 12 formed on the side walls 1, 2 protrudes and secures the vertical ladder against longitudinal displacement.
the webs 23, 24 also molded onto the side walls secure the vertical ladder 5, 6 against lateral displacement.
a further definition of all vertical ladders and all busbar connecting conductors 11 is made by rigid connection to the fuse receiving contacts 8 and 8 ', which have sideways directed projections 13 which engage in recesses in the side walls 1, 2.
the fuse receiving contacts 8 and 8 ' which have sideways directed projections 13 which engage in recesses in the side walls 1, 2.
spacer 14 made of insulating material that is resistant to leakage current, which absorbs any bending moments that may occur when tightening screw connections.
the switching flaps provided with molded-on grip webs 21 each have a cam 15 on each side, which is slidably guided in an associated groove (or slot) 16.
the switching flaps are also suspended on two lateral levers 17, which are mounted on the corresponding switching flap and the side walls 1, 2 at pivot points 18, 3 '.
the spacers 3 ' are selected as pivot points on the bar.
the lower lateral levers 17 have been shown broken off in FIG. 1.
An indentation 19 is formed in each of the grooves 16 as a locking point, into which the cams 15 of the switching flaps fit, so that an intermediate position of the switching flaps corresponding to the position of the switching flap 4 ′ shown in FIG. 2 is made possible.
the sequence of movements of the switching flaps when they are actuated can be seen from FIG. 2.
the cap 4 is in the switched-on position, the cams 15 guided in the groove 16 occupying a lower position.
the flaps are pivoted until they reach the intermediate position according to the position of the switching flap 4 'by moving the cams 15 into the bulge 19.
the cams 15 finally move to the upper end of the groove 16, which at the same time serves as a stop for the flap end position (see position of the flap 4 ").
the receptacle contacts 8, 8 ' are covered by protective hoods 20, 20', 20 ", in such a way that a common protective hood 20 is associated with different phases of adjacent receptacle contacts 8, 8 ', while the top and the bottom receptacle contacts the Each strip receives a single protective hood 20 ', 20 ". 2, the protective hoods 20 ', 20 “are disassembled parts of a protective hood 20.
fastening tabs 22 can be attached.
individual parts which have a complicated shape, in particular the side walls 1, 2, the switching flaps 4, 4 ', 4 "and the protective hoods 20 are produced as molded plastic parts.
the present invention naturally also includes the mechanical reversal of the groove or slot guide, in which case the grooves or slots can be formed in the switching flaps 4, 4 ', 4 "and the cams 15 can be formed on the side walls 1, 2.
a spring (not shown here) or other latching device can be attached, which locks the switching flap in the off position.
