Definitions

  • the invention relates to a mounting element for cable duct channels made of plastic according to the preamble of claim 1.
  • Such a mounting element for cable routing channels is known from GB-A-2 065 988. It consists of a cubic housing.
  • a fastening plate is provided, which is made from metal or the like by punching and embossing.
  • the mounting plate consists of two parts that can be folded along a center line. In the area of the center line, projections are provided on both parts, which are inserted into the groove of the cable routing channel. If the two parts of the mounting plate are unfolded, the projections lie against the walls of the grooves. The mounting plate is held in its expanded, flat position by the attached housing.
  • a disadvantage of this known element is that it consists of two parts. A change in its position in the cable duct is only possible after removing the housing, which in turn carries the electrical installation devices.
  • DE-GM 1 979 323 shows another mounting element for cable routing channels. It is a bent sheet metal part which is fastened in the grooves of the cable routing channel with the aid of screws and slide nuts.
  • the slide nuts have to be individually threaded into the grooves and pushed into the right place, which can be very cumbersome with long cable ducting.
  • the use of three separate parts is not very easy to assemble.
  • a disadvantage of both assembly elements is that it is not possible to maintain the subdivision of the cable duct with the aid of partitions in the area of the assembly elements.
  • the present invention has for its object to provide a mounting element of the type mentioned, which can be attached to any point of the cable duct and released again without having to be screwed or pushed sideways, and which high forces or weights safely and without Allows transfer of risk of damage to the cable duct.
  • the mounting element according to the invention consists of two parts, preferably made of plastic, a base part, which essentially consists of a flat trough and a molded-on housing part, and a cover part, which closes the trough.
  • the cover part is usually formed by the bottom of a switch housing, a fuse housing, etc. It is essential that the mounting element is built as flat as possible so as not to limit the space for the components to be mounted in the cable guide channel by means of the mounting element.
  • Essential for the present invention is the attachment of the mounting element by means of the two rows of claws, which - driven by the eccentric - spread and closed and can be pulled up or moved away from the base part by the action of the space cams. These claws reach behind both legs of the longitudinal groove simultaneously and in this way transmit the forces more evenly.
  • a further reduction in the punctual load results from the support feet arranged on the longitudinal side of the base part, which transfer part of the forces directly to the mounting wall of the cable guide channel, so that the groove does not have to absorb all the forces alone.
  • the claws have an anvil shape in the area in which they come into contact with the groove. This makes it possible to make the load-bearing surface of the claws as large as possible without the claws interfering with one another during the movement.
  • the cover part has a longitudinal nose pointing towards the longitudinal slot. This longitudinal nose ensures that the claws are pressed out of the housing in the closed state, so that a perfect installation is possible even if the mounting element is to be inserted overhead into a cable duct.
  • An alternative is the use of a spring which is inserted between the cover part and the sheet metal part and which, in the closed state, pushes the claws out of the housing against gravity.
  • the two sheet metal parts between the molded claws each have a fork, with a fork preferably being moved to another plane by bending it twice.
  • a double eccentric interacts with the forks, the eccentric parts of which preferably lie in two mutually parallel planes.
  • the use of a double eccentric has the advantage that, when the claws are spread or closed, both sheet metal parts are displaced relative to one another, so that the mounting element does not move in the groove when mounting or removing.
  • Eccentric and forks Hegen * preferably in the area of an actuating housing, which is formed on a narrow side of the tub and forms the bottom part together with this.
  • the holding part and the actuating part are clearly separated from one another in this way.
  • the actuating part can always be of the same design, while the holding part can be adapted to the circumstances of the individual case.
  • the cable duct is divided by suspended partition walls.
  • the actuator housing is also provided preferably a partition is provided.
  • the eccentric is advantageously accessed via a tubular opening on the top of the actuating housing.
  • the guide pins serve at the same time for fastening the cover part to the base part.
  • the connection is made, for example, by screwing, gluing or ultrasonic welding.
  • a base part 1 can be seen, which is formed by a flat, rectangular trough 2 and an actuating housing 3 formed on its narrow side.
  • the side walls 5 of the tub 2 are shaped so that they can accommodate a cover part (not shown here).
  • Space cams 6 are formed on both sides of this longitudinal slot 13 at regular intervals with an inclined ramp 7.
  • Guide pins 12 are also formed at regular intervals in the trough between the side walls 5 and the longitudinal slot 13.
  • a central guide lug 8 is provided on the underside of the actuating housing 3, which facilitates the insertion of the mounting element into the grooves of the cable guide channel.
  • the top of the housing part 3 is provided with a central opening 9 into which an eccentric (not shown here) can be inserted.
  • a partition 10 and an insulating tube 11 are also arranged on the upper side of the actuating part 3. The tube 11 allows access to the eccentric in order to be able to actuate it, for example, with the aid of a screwdriver.
  • FIG. 3 and 4 show a sheet metal part 20, in which guide holes 21, which form an obtuse angle, are punched at regular intervals. These guide holes 21 interact with the guide pins 12 in the tub 2.
  • Sheet metal flags 26 are bent at right angles on the sheet metal parts 20, on which in turn anvil-shaped claws 22 are formed at right angles.
  • At the left end of the sheet metal part 20 there is a second fork 24.
  • both sheet metal parts 20 can be produced from a stamped and bent part.
  • the forks of the two sheet metal parts come to lie one above the other in the actuating housing 3 and the claws 22 of the two sheet metal parts can move past one another without interference.
  • Fig. 5 shows a longitudinal slot through a mounting element consisting of tub 2, actuating housing 3 and cover part 14. It can be seen how the claws 22 and the metal tabs 26 can reach through the longitudinal slot 13.
  • a double eccentric 34 with a first eccentric part 31, which interacts with the fork 24, and a second eccentric part 33, which interacts with the fork 23.
  • Disks 30, 32, 35 are provided for guiding and holding the forks 23, 24.
  • FIGS. 6-11 show the position of the eccentric head 34, sheet metal parts 20 and claws 22, with FIGS. 6 and 7 the claws in the closed state, FIGS. 8 and 9 the claws in the spread state and FIGS. 10 and 11 show the claws in a spread and tense condition.
  • the metal tabs 26 rest on the bottom of the tub 2.
  • a formed on the cover part 14, the longitudinal slot 13 facing longitudinal nose 15 presses the sheet metal parts 20 on the tub bottom, so that the claws 22 are pressed out of the slot 13. This facilitates the assembly and disassembly of the assembly element.
  • the mounting element can be inserted in a simple manner into the C-shaped groove 31 of the mounting rear wall 30 of a cable routing channel.
  • the eccentric 34 has performed a rotation of approximately 90 °.
  • the sheet metal parts 20, under the influence of the guide pins 12 and the guide holes 21 forming an obtuse angle, have moved outwards, which has triggered the expansion process.
  • the metal tabs 26 are just beginning to slide up the ramps 7 of the space cams 6.
  • the spread state of the claws 22 can be seen well in FIG. 9.
  • the claws 22 already engage behind the C-shaped cross section of the groove 31.
  • the connection is however still so loose that the mounting part can be easily pushed back and forth in the groove if necessary can be.
  • the eccentric 34 has carried out a further 90 ° rotation.
  • the metal tabs 26 of the sheet metal parts 20 have run up onto the space cams 6 via the ramps 7.
  • the claws 22 are attracted to the C-shaped cross section of the groove 31, which can be seen particularly well in FIG. 11.
  • both rows of support feet 4 are supported against the mounting rear wall of the cable routing channel 30, as a result of which the forces which are exerted on the mounting element are transmitted uniformly to the cable routing channel.
  • the cover part 14 Since the external forces that are to be transmitted to the cable routing channel are primarily exerted on the cover part 14, a connection between the cover part 14 and the base part 2 is recommended not only in the area of the edge 5 but as far as possible over the entire surface. Since this is not possible, the guide pins 12 and the space cams 6 are used for the attachment between the base part and the cover part, the attachment being able to be carried out by means of screws, gluing, welding, etc.
  • the bottom part and the lid part viewed in the longitudinal direction of the mounting element — are connected to one another at a total of six rows of fastening points, which results in a very stable connection and the mounting part itself has a high degree of internal stability.
