Low-voltage distributor insert, especially for installation

in cable distribution cabinets

The innovation relates to a low-voltage distributor insert, in particular for installation in cable distribution cabinets with a Number of NH fuses is provided, and for which the Fuses required mating contacts as well as busbars and supply bars are attached to an insulating material carrier.

An arrangement has already become known in which the busbars, Feed rails and the mating contacts intended to accommodate the NH fuses are attached to an insulating material carrier are, which is designed as a rearwardly open hollow body. The Isollerstoffträger has steps on which the Mating contacts and the cable connections are arranged. At this Arrangement, the current-carrying components are freely accessible, so that protection against accidental contact is not provided. In addition, the Steps have an unfavorable effect in terms of the space required for the arrangement in depth. ;

The innovation avoids the aforementioned disadvantages and provides that the insulating carrier is designed as a hollow body consisting of two half-shells, in which the mating contacts and the feed rails are held and one half-shell of which has openings into which the NH fuses are inserted, while the busbars are attached to the outside of the other half-shell and the electrical connections between the busbars and the associated mating contacts are passed through openings provided in this half-shell * This arrangement saves space and offers extensive protection against accidental contact. 7; 7- ■ ".- '■ ■■■ ■ ^: / - Λ7 - 7 / ■■." ■

It is also provided according to the innovation that the openings are adapted to the shape of the NH fuses in the half-shell. This has the advantage that the delimitation edges of the openings guide the fuses during Onset is achieved.

According to a further refinement of the innovation, the NH fuses are offset from one another in rows one on top of the other and their contact ends are arranged in an interlocking manner. With this arrangement, a reduction in the overall height of the insert is achieved, which brings the /.Vorteil-, a possible reduction in the size of the viewing area or a larger connection space for the cable. 7 _"77: - - / 7 / ^/; 7; ^/ - 7 - --- / -" ■■ - - γ 77 7; / - / -. /

According to an expedient further development of the innovation, it is provided that that the feed rails, at their ends counter contacts are firmly arranged by clamping between the half-shells are held and thereby on the inside of the half-shells provided cams and ribs and through into the lower Edges of the half-shells provided recesses are made of the fact that the holder of the feed rails and the associated mating contact © is made by clamping,

a simple and quick assembly of the insert is made possible, whereby a considerable reduction of the manufacturing costs is achieved.

Further, according to the innovation, are in the lower edges of the half-shells Ventilation openings and ventilation openings provided in the upper edges, the effective cross-section being the Ventilation openings is smaller than that of the ventilation openings. With this design and arrangement of the ventilation openings, the insert is effectively ventilated by the chimney effect achieved.

Further advantages of using the innovation are that it is designed to be self-supporting and can be easily assembled on site.

In Figures 1 to 7, the subject of the innovation is shown for example. Show it

Form the support body of the insert and, as in Flg. β is shown, are held together by screws 3. The front half-shell 1 has openings 4 into which NH fuses 3 are inserted. The insert has twelve fuses, which are offset from one another in three superimposed rows of four fuses each and are arranged with their contact ends 5a interlocking. The fuses are held by mating contacts β and 7 designed as spring contacts, the contact ends of which protrude from the openings. The mating contacts 6 are each firmly connected to a feed rail 8 to. The feed rails are held between the half-shells 1 and 2 by clamping, and they rest against cams 20 (FIG. 7) provided on the inside of the rear half-shell 2 and in part against ribs 21. The cams are arranged to hold the feed rails in place. The ribs also provide support for the rails in the event of a short circuit. The feed rails 8 to 19 are guided downward through recesses 22 provided in the lower edges la and 2a of the half-shells. The gap 23 provided between the half-shells ensures that, regardless of manufacturing tolerances, the half-shells always come to rest firmly on the narrow sides of the feed rails.

The mating contacts 7 arranged in the half-shell 2 (Fig. 2) are with Sanimel rails arranged on the outside of this half-shell Connected via common screws, which are also electrical Represent connections 25, and which are led through openings 26 provided in the half-neck.

In the lower edges la and 2a of the half-shells, recesses are provided which result in circular ventilation openings 27, while in the upper edges Ib and 2b arranged elongated recesses rectangular ventilation openings 28 (Fig. 3) can be obtained.

For holding the insert, for example in a cable distribution cabinet, are used on the back of the half-shells 2 arranged support plates 29, which are not shown perpendicular Have elongated holes so that the distributor insert can be hung and fastened in a cabinet.

As indicated in Fig. 1 and J> with dashed lines for a further low-voltage distributor insert, several inserts can be arranged directly next to one another in a space-saving manner, with the cranked ends 24a of the hammer provided with a bore providing a simple connection by means of push-through screws with the straight ones Ends of the busbars of the next use is made possible.
