Description

The invention relates to a housing for accommodating electrical units, in particular additional housing for electrical switch drive boxes for ! load switch, which is cuboid from the rear wall, side walls and a movable cover is designed, with one of the side walls, has at least one through hole for electrical leads.

In catenary systems, in existing catenary networks in increasingly in the context of rationalization and Extension measures for electrical switch drives for mast switches used, the electrical switch drive is in a box, which is now usually made of light metal. Of the Box has a cuboid shape, consisting of a rear wall and side walls, with the box on the front by a large-area lid is covered. This peckel is on the lower one, front edge of the box with hinges movably supported, whereby when opening the lid the same is clipped 180 degrees downwards. After opening the lid hangs freely movable downwards, so that in the When the box is open, a good overview of the electrical switch drive located therein is guaranteed.

There are still a large number of such boxes in the railway sector today for mast switches with electric motor drives. However, in this case the existing boxes are retained. It has now been shown that when using the existing boxes for the retrofitting of the space inside the box for the accommodation of additional electrical control units or electrical distributors or other additional units are not sufficient. On the other hand, they should can still be used in a variety of existing boxes.

It must be taken into account that the cover of the switch drive box, due to its predetermined mounting by means of two hinges on the lower front edge, swings 180 degrees downwards when it is fully opened and a few centimeters to the rear in terms of its width
is set back in the area back below the lower side wall. When constructing an additional housing for the switch drive box, that is through the opened cover

the same limited space below the lower side wall on the one hand and on the other hand, to take into account the specified lead-through opening within the lower side wall of the Scholteron drive box, here in usually two through holes in the interior of the

Counter drive costs are available.

The invention is therefore based on the object to provide a housing Accommodation of electrical units, in particular an additional housing for electrical switch drive boxes for mast switches to create which the complete opening of the cover of the switch operating mechanism box by 180 degrees freely downwards and at the same time a faultless one Cabling between the units within this housing and the electrical switch drive within the switch drive box ensures.

According to the invention, this object is achieved in the characteristics of claim 1, an advantageous embodiment in the characteristics of claims 1 and 2. Further inventive embodiments are in the Subclaims 3 to 6 characterized.

The decisive advantage of the housing according to the invention is that that due to the resetting of the same by means of the inclined extension piece of the cover of the scarf teremtriebskastens completely by 180 Degrees can be folded down without the same on the housing bumps. The housing thus offers a compromise between the arrangement of the two through holes for cable feeds within the lower side wall of the switch drive box, these holes are relatively close to the front edge of the switch drive box and the Utilization of space below the switch drive box leaving a space for the cover of the switch drive box up to free hanging opening of the lid downwards. The other culminates in this Extension piece preferably slightly off-center of the upper side wall of the housing offset in the direction of the front longitudinal edge of the upper Side wall, so that a favorable weight distribution of the housing when flanged to a switch drive box is achieved.

Furthermore, the extension piece is advantageously double executed, each for a through hole within the lower, side wall of the SchaUerantriebskastens, each Extension piece has a separate through channel for separate cable routing and additionally both extension pieces through one Connection rib can be connected for mechanical stiffening. In' In this case, the ends of the two extension pieces are by means of a Double mounting flange with which the housing is flanged to the lower side wall of the switch operating mechanism box. Additionally can be used to further strengthen the double fastening CNC and the two attachment pieces between the two a lower stiffening rib be arranged, which extends perpendicular to the connecting rib of the two extension pieces and which is at the same time with the double flange is designed integrated. This gives the neck-shaped extension piece of the housing a high level of stability against mechanical stress.

An example of the invention is shown in the drawing and described below. Show:

flanged housing.

The housing, which is preferably designed as an additional housing for electrical switch drive boxes for mast switches, is in the figures with the reference number 1, designed cuboid and consists of a rear wall 2, an upper side wall 3, a lower Side wall 4 and two approximately perpendicularly arranged side walls 43, 44 (FIG. 2), the walls being connected to one another in one piece. The housing 1 is closed by a cover 6 which is arranged vertically and parallel to the rear wall 2 and which is secured by means of screws 8, which are shown in FIG Engage threaded holes, is releasably attached. Inside the housing are laterally in the area of the vertical side walls 43, 44 supports 19 molded with threaded holes onto which e.g. a mounting rail (not shown) for electrical distribution can be screwed. Furthermore are

.. on the rear wall 2 inside the housing and in the area of the corners

the same screw support 20,21 molded. That has a countersink

: can have for drilling through the screw supports 20,21, if the

Housing 1 should be mounted vertically on a wall. Further are located in the area of the screw supports 20, 21 on the outside of the Rear wall 2 reinforcement spacers 27, 28 and 29, which are used in the Said type of fastening can also be drilled through for the throughput of fastening screws.

The cover is on the housing 1 with a sealing ring 7 in between screwed on, the sealing ring in one on all end faces

, the side walls circumferential sealing groove 36 is arranged. Further

has the housing 1 in its lower side wall 4 three

j through holes 31, 32 and 33 to accommodate cable terminations 9,

one of which is shown in FIG. The cable terminations are preferably made by means of flanges and screws arranged on them 10 fastened with lock nuts through screw holes 34,35 within the lower side wall 4 and through the flanges of the Cable terminations 9 protrude. By means of the cable terminations 9, electrical leads are introduced into the housing 1 and there accordingly further distributed.

For fastening the housing 1 to a switch mechanism K-asten 37 (Fig 5), which is the preferred use of the housing 1, has the same thing: on the upper side wall 3, two extension pieces 11, 23, each one

have separate through-channel 12, 42 for separate cable routing. The through channels can have any cross section, in In the example shown here, the cross section of the through channels 12, 42 is circular. The extension pieces 11,23 run obliquely upwards and are inclined towards the front to the cover 6 or to the cover plane 15 on the Side wall 3 arranged and formed in one piece with this. Furthermore, the extension pieces 11, 23 are in a front view of the cover 6 arranged next to one another parallel to the front edge of the upper side wall 3. The base of the extension pieces 11, 23 is preferred arranged off-center of the upper side wall (3) towards the front longitudinal edge of the housing (1), so that an even more favorable Weight distribution of the housing 1 results. However, the base point of the extension pieces 11, 23 can be positioned centrally within the upper side wall 3 be arranged, in which case the angle of inclination of the extension pieces 11,23 measured relative to the vertical becomes greater.

The ends of the extension pieces 11,23 carry a mounting flange that is designed here as a double mounting flange 13. With this double mounting flange 13, the housing 1 is attached to a Switch drive box 37 flanged to its lower side wall 17, so that the upper openings 25 of the extension pieces 11,23 exactly with the " two holes 22 within the lower side wall 17 of the switch drive box 37 are aligned. The length and slope of the Extension pieces 11,23 is preferably such that the upper openings 25 of the extension pieces 11,23 touch the cover plane 15 or almost touch.

In Figure 5 is the attachment of a housing 1 to a Switch drive box 37 shown. This has a cover 38 which is about an axis of rotation 39 in the direction of the curved arrow 41 when opening Pivots 180 degrees downward, with the front of the lid 38 of the Switch drive box 37 coincides with the dotted line 40 when hanging freely downward, so that the cover 38 in this Position just rests against the screws 8 of the cover 6 of the additional housing 1. That way, the front room is directly below of the cover 38 of the switch drive box 37 free for opening the switch drive box 37 at any time without the housing I opening of the switch drive box 37 obstructed. Due to the inclined extension pieces 11,23, the housing 1 is outside of the Swivel range of the cover 38 of the actuator drive box 37.

Furthermore, the extension pieces 11, 23 are used for mechanical stiffening connected to one another centrally over their entire length by means of a connecting rib 24. In addition, in the middle of the Connecting rib 24 a stiffening rib 14 extending perpendicular to this may be arranged, which is located between the underside of the double mounting flange 13 and the top of the upper side wall 3 extends. When flanging the housing I to the lower A seal 16 is arranged between the side wall 17 of the log drive box 37 by means of the screws 18 and lock nuts.
