  • holes 16 are provided on the rear side of the beams for holding the switching units mounted on the guide rails 17.
  • Each rail 17 has, at its opposite ends and middle, tongues 18 and 19, respectively, which are adapted to fit detachably and simply into said fitting holes 14 and 15 respectively.
  • Each of said end-tongues l8 and the middletongue 19 has slits 20 and 21, respectively.
  • the rail 17 can be held in place on the beam 124 or 12b only by inserting its tongues 18 and 19 into respective holes 14 and 15 of the pillar 12a or 12b and then moving it downwardly.
  • the rail 17 is securely attached to the pillar 12 without the necessity of using any fasteners, screws, etc.
  • these rails 17 can readily be mounted on the beams 12a, 12b at a desired position, properly spaced from one another, depending on the height of switching unit to be mounted, without employing screws or any tools.
  • the beam 120 is provided with a vertically extending channel 13 formed on the outer side as shown in FIG. 4.
  • the beam 12a only is provided with said channel; however, the beam 12b also may be provided with a similar channel.
  • Said channel 13 serves to accommodate bundled wires, the details of which will be described hereinafter.
  • FIG. shows a schematic view of the switching unit 24 in which a plurality of electric elements (not shown) have been already accommodated.
  • Switching unit 24 is provided with a multi-pole connector plug 25 connected with said elements which extends around the rear side of the switching unit 24, via surface wiring 27.
  • Mounting tabs 26 are designed so as to be fastened to the beams, for example, by means of fasteners which engage the respective holes 16 on the beams 12a and 12b.
  • the electrical interconnection between a plurality of switching units 24, and also between the associated panels is accomplished by using connectors on panel unit 28 as shown in FIG. 6.
  • multipole connector sockets 29 are secured to a plate 28a, the number of the sockets equalling the number of plugs of the switching units 24 to be mounted on the frame unit 11.
  • These fixed sockets 29 are in connection with one another via bundled wires 33.
  • the bundled wires 33 are held by means of holders 30 and are extended further for connection to another connector panel or terminal plate 34.
  • This terminal plate 34 allows interconnection between the associated frame or panels.
  • the connector panel unit 28 has arms 31 and 32 fixed at its upper and lower ends of the plate 28a, respectively.
  • the extreme end portions 310, 32a of the arms 31, 32 can be fixed in the channel 13 formed in the beam 12a shown in FIG. 3, so that the connector panel unit 28 and the frame unit 11 are securely connected together.
  • the bundled wires 33 are accommodated within the channel 13. In this manner, there can be provided a protecting effect for the bundled wires 33 and also a good external appearance. Moreover, this arrangement also attains the effect of substantially reducing the width of the apparatus.
  • said arms 31, 32 serve as journal supports for a shaft fixed to a cabinet as shown in FIG. 1. Therefore, these arms 31, 32 enable pivotal movement around said shaft so as to permit opening and closing of the apparatus relative to the cabinet.
  • said shaft is shown at 35, and the journal supports on the arms 31 and 32 are shown at 31b and 32b, respectively.
  • FIG. 7 is a partly sectional view of the apparatus showing how the bundled wires 33 of the connector panel unit 28 are received in the recess 13 formed on the pillar 12a of the frame unit 11. As described previously, it is possible to provide protection of the bundled wires 33 and also present a good external appearance due to no visible exposure of the bundled wires. FIG. 7 also shows how the connector plug 25 is connected to the connector socket 29.
  • the switching units 24, the frame unit 11, and the connector panel unit 28, described above, can be individually pre-fabricated at the factory. These prefabricated units are separately transported from the shop to the installing site. At the site the units are assembled into the apparatus in such a manner that: firstly, the connector panel unit 28 is mounted to the supporting member, for example, the shaft 35 shown in FIG. 6; then, the frame unit 11 is fixed to the arms 31 and 32 of the connector panel unit, and; finally, the electrical units 24 are mounted to the frame unit 11.
  • the major advantage of the present invention is that the apparatus is constructionally separable into the above-described three components.
  • This separable structure of the present apparatus eliminates the necessity for handling of a large and heavy assembled apparatus. Accordingly it enables simplification and savings in labor in manufacturing, transporting, assembling, and installing.
  • Another important advantage is the facilitation of electrical connection between units 24 or between frames 11.
  • the electrical connections between the switching units 24 are instantly and simply completed by connecting plugs 25 with the sockets 29.
  • the electrical connections between the panels can be accomplished prior to mounting in the frame unit by connecting the bundled wires 33 of the connector panel unit 28 via the terminal plate 34. This connecting work is very easy due to the existence of the wide free-space in the cabinet.
  • the electrical connection in the present apparatus can be accomplished at the installing site in a much more simple manner and also in a short time.
  • the present apparatus has an important advantage that the rail 17, for mounting the switching units thereon, can be attached to the pillar without the use of any screws and, accordingly, without any assembling tools. Therefore, every rail is readily detachable so that its position may be properly located according to the height of each switching unit to be mounted. This is more effective in a case where it is desired to mount an additional switching unit between the units already mounted.
  • a further advantage is the facilitation of wiring. That is, the bunched wires are limited to only the connection in the connector panel unit 28 and the wiring in the switching unit can be accomplished by surface wiring. In the prior art apparatus, the electrical connection between the switching units had also been previously done by the bunched wire technique at the factory.
  • a panel system comprising,
  • electromechanical units each having a plurality of electrical elements accommodated therein, and plugs connected with said elements via electrical wires;
  • each of said vertical beams having a plurality of sets of fitting holes at the inner a connector panel unit having vertical means on which a plurality of sockets are disposed to which said plugs removably attached, wires electrically interconnecting said plugs, and arms fixed at the upper and lower ends of said vertical means which engage said frame unit and pivotally engage a supporting member for the apparatus, and said wires being disposed to extend laterally from said vertical means so as to be received within said channel.
