Definitions

  • the invention relates to an adapter for installing switching and/or safety equipment in a cabinet or the like of a low- voltage distribution unit, said adapter comprising at least one baseplate and two side walls extending transversely to the baseplate, at least substantially parallel to each other, on one side of the baseplate means for connection to bus bars mounted in said cabinet or the like are provided, and on the other side of the baseplate means for mounting switching and/or safety equipment are provided.
  • an adapter which is known from European patent application No. 1 137 137, is used for mechanically and electrically installing the equipment in the unit.
  • the side walls of this known construction are made up of bent-over parts of the sheet metal baseplate, so that the adapter can only be used in combination with specific switching and/or safety equipment having corresponding dimensions.
  • the side walls are separate members, which can be connected to the baseplate.
  • the side walls can be detachably connected to the baseplate without using any further fixing devices and/or tools, thus making it possible to connect the side walls to a baseplate in a quick and simple manner.
  • each side plate is provided with two spaced-apart hammerheads
  • the baseplate is provided with recesses at opposed side edges for accommodating necks of said hammerheads, which enables easy connection of the side walls to a baseplate by sliding the necks of the hammerheads into the recesses in the baseplate, whereby the baseplate will be retained between parts of the side wall located on either side of the necks of the hammerheads.
  • holes are present in the baseplate at positions spaced from the recesses for receiving spring hooks that are attached to the side walls.
  • An efficient embodiment of the side wall comprises two plate-shaped members extending perpendicularly to each other, one of which plate-shaped members extends parallel to the baseplate, partially overlapping it.
  • a U-shaped adapter is obtained, which is capable of accommodating all kinds of switching and/or safety equipment in the space between the upright legs, which equipment can subsequently be protected from being touched in a simple manner by attaching a screening plate to the ends of the upright legs.
  • Such adapters can be assembled and tested in larger numbers in a simple manner without any risk of damage or electrocution.
  • the side wall comprises block- shaped members on either side thereof.
  • space is created between the baseplate and the part of the side wall that extends parallel thereto for accommodating all kinds of auxiliary equipment, such as an auxiliary bus bar unit.
  • the side wall is made of a plastic material, as a result of which the side wall can be formed in large numbers by means of a mould, in spite of its complicated shape.
  • the side wall is configured such that a relatively simple mould can be used, which only needs to be closed and subsequently opened without using separate mould parts.
  • Fig. 1 is a perspective view of an adapter and equipment in the form of so-called quick break switches connected thereto, as well as plug contacts connected thereto.
  • Fig. 2 is a view corresponding to Fig.
  • Fig. 3 is a perspective view of a side wall on the side that faces away from the other side plate in the mounted position of the side wall on the baseplate.
  • Fig. 4 is a perspective view of a side wall, on the side that faces towards the other side wall in the mounted position of the adapter.
  • Fig. 5 is a top plan view of a side wall, on the side that is shown in Fig. 3.
  • the device as shown in the figures comprises a baseplate 1 and two side walls 2 and 3 extending transversely to the baseplate, at least substantially parallel to each other, which side walls are preferably of identical construction. As is shown for the side wall 2 in Figs.
  • the side wall comprises two plate-shaped members 4 and 5 extending perpendicularly to each other, said member 4 extending parallel to the baseplate and being partially overlapped thereby.
  • the plate-shaped member 5 comprises a comb- shaped portion 5 1 extending parallel thereto, which is provided with spaced-apart teeth 6 and with recesses 7 between said teeth.
  • Several openings 4' and 4 M are present in the member 4.
  • the ends of the members 4 and 5 are interconnected by block-shaped members 8. A receiving space is created between the facing ends of the block-shaped members 8 and the two members 4 and 5 for receiving an auxiliary bus bar unit 9 (Fig. 2).
  • This auxiliary bus bar unit 9 can be locked in position in the receiving space by means of spring hooks 10 present on the facing boundary surfaces of the block-shaped members 8, which hooks will snap into recesses formed in the ends of the auxiliary bus bar unit 9 upon insertion of the auxiliary bus bar unit 9 in the respective receiving spaces.
  • Hammerheads 11 are present on end surfaces of the block- shaped members 8, each hammerhead having a neck 12 and a wider head portion 13, as is shown in particular in Fig. 5.
  • the block-shaped members 8 are furthermore provided with a number of bores 14 and 15 for the passage therethrough of bolts, as will be described in more detail yet hereinafter.
  • the plate- shaped member 5 is provided with wedge-shaped run-on surfaces 16 at the longitudinal edge remote from the teeth 6, the height of which surfaces gradually increases in a direction away from the lower boundary edge, seen in Fig.3, of the wall member 5.
  • the necks 12 of the hammerheads 11 are slid into recesses 17 formed in the baseplate 1, which recesses are open at the upper edge of the baseplate 1, seen in Fig. 2.
  • the baseplate will be retained between parts of the side wall 2 in question located on either side of the necks 12.
  • the lower side wall 3 can be connected to the baseplate 1 by sliding the respective necks into recesses 18 being in line with the recesses 17, which recesses 18 are formed near the lower edge of the baseplate 1, seen in Fig. 2.
  • a corresponding elongated recess 19 is present in the baseplate, as will be apparent from Fig. 2.
  • a bus bar 20 having a desired length is mounted on the baseplate 1 on the side of the baseplate remote from the side walls 2 and 3 for connecting switching and/or safety equipment thereto, such as the quick break switches 21 that are schematically shown in Fig. 1. As is furthermore shown in Figs.
  • a number of plug contacts 22 are present on the side wall 2, by means of which plug contacts the above-described adapter can be connected to a bus bar system present in the cabinet or the like of a low-voltage distribution unit, and by means of which the adapter is mechanically and electrically installed in the distribution unit.
  • Each plug contact 22 comprises a housing 23 being integral therewith, which housing is provided with spring lips 24, which will slide over associated wedge-shaped run-up surfaces 16 upon connection of the housing 21 to the wall member 5 and snap behind said wedge-shaped run-up surfaces 16 at some point so as to mechanically secure the plug contact in position on the wall member 5. In that position, a connecting strip (not shown) of the plug contact is supported by support ribs 25 present on the wall member 4.
  • the plug contacts 22 and also the auxiliary bus bar unit 9 can be provided at the upper side of the baseplate 1 or at the lower side thereof, seen in Figs. 1 and 2, thus excluding the risk of errors caused by the side walls being mistaken for one another. Furthermore, the side walls may be used in combination with baseplates of varying length and/or height.
  • the auxiliary bus bar unit 9 consists of an extruded section of plastic material, e.g. which is provided with four mutually insulated conductors, to which equipment, such as the quick break switches 21, can be connected, for example by means of flat plugs.
  • the auxiliary bus bar unit may be provided with power supply cables for connection to the plug contacts 22, which cables can be passed through the openings 4 1 in the plate-shaped member 4.
  • the U-shaped space between the side walls 2 and 3, in which wiring or copper strips may be present for making the required connections to the plug contacts, can be closed by means of a cover, which can be secured in position by means of ears 26 forming part of the side walls 2 and 3.
  • the auxiliary unit and the components connected thereto can be secured in position in the cabinet or the like of the distribution unit in question by means of screws or bolts that are passed through the holes 14.
  • the side walls 2 and 3 may also be fixed to the baseplate 1 by means of screws passed through the holes 15.
