l ELECTRICAL-INSTALLATION SYSTEM
l ELECTRICAL-INSTALLATION SYSTEM
2 The invention concerns an electrical-installation system 3 involving junction boxes that accommodate electrical fittings ~ like switches, consumer equipment, outlets, communications devices, etc. An installation system of this type is 6 described in German OS 3 004 950.
8 That system involves boxes that accommodate electrical 9 equipment. Embedded into the base of the boxes are conductive strips. The strips in adjacent boxes are 11 connected by connectors that also combine the boxes into an 12 installation system. Once the system has been installed, 13 however, it is no longer possible to separate its components 14 and the user is stuck with the original connections.
16 A surge-protected connecting and distributing box for 17 communications is disclosed in German OS 2 341 232, which 18 describes the boxes as having a definite elevation at the 19 base or an elevation in the lid. This external characteristic, however, is intended only to inform the user 21 of the surge protection.
23 German OS 3 431 836 describes an installation device 24 intended for connecting switches, outlets, dimmers, antenna leads, and similar fittings. The object is to replace the 26 device, which dictates the specific electric function, as 27 simply as possible. A single type of base plate accepts such 28 different types of connecting cable as power cords, antenna 29 cables, etc. The~e is, however~ a drawback to this system in that the speci~ic electrical function of the individual 20~04~8 1 devices is in the form of completely encapsulated plug-in 2 modules.

4 With the state of the art summarized in the foregoing as a point of departure, the object of the present invention is to 6 provide basic components in accordance with the known 7 principle of installation that will be simple to manufacture 8 and easy to install, comprising a stable dimensional 9 structure and allowing modifications to be undertaken as far as the installed areas when the user so wishes. It must be 11 emphasized, however, that it is not such eonsumer equipment 12 as switches, plugs, ete. that are involved, but the basic 13 unit of the installation system.
This objeet is attained in aceordanee with the invention in 16 that junetion boxes with one or more aceommodations are 17 ereated by providing permanent wiring at the base that can, 18 however, when neeessary be replaced with wiring of a 19 different structure. The boxes ean also be easily aligned at a desired distanee apart. Aeeess from the equipment is 21 provided by way of prefabrieated equipment-end lines and a 22 simple system of plugs to the assoeiated eonduetors at the 23 base.
The junetion boxes employed in aeeordanee with the invention 26 are basieally of eonventional design. It must be emphasized 27 in partieular that break-out entranees and passages have been 28 stamped into their sides, through whieh the system can be 29 provided with incoming and outgoing lines. The distribution of the eondueting eontact rails over the base of the boxes, 2050~g 1 embedded in a recess in the base in one special embodiment, 2 constitutes the simplest conceivable solution for 3 associating such a rail with the box. Power cords, circuit 4 lines, and consumer equipment, the last by way of connecting lines from the equipment, can be individually connected, 6 depending on the wiring diagram, to the strips associated 7 with each box. A system of this type can definitely be 8 constructed in accordance with the thresholds dictated by 9 safety regulations, with at least five installation areas being aimed at. It has been demonstrated as especially 11 practical that any modifications all the way down to 12 separating and assembling installation areas can easily be 13 underta~en subsequently, once the system has been installed, 14 that is, at the connections themselves without having to interfere in the building structure in any way 17 The embodiments of the invention recited in the subsidiary 18 claims round the overall system off. In the sense of 19 providing the basic units that assemble into the installation system with adequate stability it has been demonstrated as 21 practical to make the basic units, the single and multiple 22 boxes, that is, interlocking. The ends of the housing in 23 another embodiment can be removed. This approach results in 24 an unimpeded passage through an installation system comprising several basic units. Assembly of the conducting 26 contact rails in individual installation areas is facilitated 27 by applying bridging wire to the cores of the rails in 28 adjacent areas. When three individual junction boxes are 29 combined, for example, the separable association of a partition that corresponds to the end with one of the 20~048~
1 housings can be provided between the installation areas in 2 order to ensure spatial and electrical separation between the 3 areas when necessary, when they are connected to different 4 supply lines for example.
s 6 One embodiment of the object of the invention will now be :
7 specified with reference to the schematic drawings, wherein 9 Yigure 1 illustrates a double junction box in accordance with the invention, 12 Figure 2 is a side view of the box, 14 Figure 3 is an end view of the box, 16 Figure 4 illustrates one of the ends that can be 17 inserted into and removed from the box illustrated 18 in Figures 1 through 3, Figure 5 is a perspective view of a conducting-21 strip holder, 23 Figure 6 illustrates a conductor contact rail that 24 can be inserted in the holder illustrated in Figure 5, 26.
27 Figure 7 is a top view of a cover associated with 28 the conducting-strip holder, Figure 8 is a top view of the mounting lid that can 2~0488 1 be placed over the double junction box illustrated 2 in Figure 1, 4 Figure 9 is a front view of the lid, and s 6 Figure 10 is an illustration of the wiring.
9 The housing 9 of the double junction box illustrated in Figures 1 through 3 consists of a base 1 that has two 11 recesses 3 and 4 with a web 2 left between them, two long 12 sides 12 and 13, and two ends 14 that can be attached to and 13 removed from it. Additional webs 5 and 6 adjoin recesses 3 14 and 4 at the sections of the base of housing 9 not covered by the recesses. Webs 2, 5, and 6 have longitudinal grooves 7 16 and 8. The purpose of the grooves is to accommodate the 17 connecting wires between the individual connection blocks 18 inside recesses 3 and 4.
To allow ends 14 to be secured to and removed from housing 9, 21 the housing and the ends are provided with interlocking 22 structures 10 and 11 and 23 projections 15 and 16 that snap into them. When for example 24 a threefold combination is employed with two different circuits, a bridge in the from of an end 14 must be inserted 26 between the double and the single box. Indentations 42 make 27 it possible in conjunction with grooves 7 and 8 for the 28 corresponding lines to also extend beneath end 14.
Housings 9 are also provided with connectors 17, 18, and 19 20~0488 1 at the ends to allow two adjacent housings to be secured 2 together. In this event the end 14 of one housing component 3 acts when necessary as a partition between the adjacent 4 contact a~eas. If modifications are made to the building S later, the partition can easily be removed and the existing 6 installation changed without any problems and without much 7 installation expense. To satisfy this function, an end 14 8 can also be inserted in an existing housing component, for 9 which purpose other connecting components 21 for example can also be provided on the housing component. Both long sides 11 12 and 13 and ends 14 can also be provided with dropouts 22 12 and passages 23. Dropouts 22 and passages 23 are normally 13 closed off and can be broken through when needed.
The recesses 3 and 4 in base 1 are completely occupied by 16 replaceable conducting-strip holders 24 made of an insulating 17 material. The holders are made of an insulating material and 18 are provided with a number of separated and adjacent channels 19 25 that have conducting contact rails 26 inserted in them.
Extending over conducting-strip holder 24 and its conducting 21 contact rails 26 is a cover 27 that interlocks with the 22 recesses 3 and 4 in the base 1 of housing 9 by way of a 23 connecter 28. Cover 27 has a number of separated 24 perforations 29 and releasing slots 30 that provide access to the conductors below it. The cords that connect the consumer 26 equipment, unillustrated in this case, that is to be attached 27 are introduced into the appropriate perforations 29. The 28 resilience of conducting contact rails 26 maintains the 29 contact. The connection is disestablished by eliminating the conductor contact rail's hold on the inserted connecting 2~0488 1 cable by acting on a releasing slot 30 in a communicating 2 cable inserted next to perforation 29 with a small, flat 3 tool.
The housing 9 of the potential embodiment illustrated in 6 Figures 1 and 2 is finished off with a mounting lid 31 that 7 locks onto the housing. The lid's attachment to;hausing 29 8 is ensured by catches 33 that engage beads 32 on long sides 9 12 and 13, constituting the interlock. This attachment can be rapidly disestablished with a screwdriver for~example, 11 providing access to the conducting-strip holders in the 12 recesses under cover 27. The holders can be replaced once 13 the cover has been removed or as an entire block.
Projecting out of mounting lid 31 are supporting rings 34 and 16 35, the purpose of which is to accommodate whatever equipment 17 is being employed. Screws 36 generate a positive connection 18 between the installed equipment and the installation system.
Depending on the particular application, the requisite number 21 of boxes are locked together by way of fasteners 17, 18, 19, 22 and 20. When a single box that is in principle designed for 23 use with the illustrated double box is available, 24 installation systems with any number of installation areas permitted by safety regulations can be constructed. The 26 resulting installation system will finally be wired to 27 confirm with the particular installation requirements by 28 securing bridging wires 37 that extend between the adjacent 29 installation areas to the conductor sections that constitute a component of the areas and are assembled in the conducting-20~0~8~
1 strip holders. The installation system is then connected to 2 a power line 38 that is part of the mains line and or also to 3 the connection 39 between the circuit lines, whereby the 4 mains line can as a rule extend through one of the ends 14 along with the circuit lines as well as through the dropouts 6 22 and passages 23 through the long sides 12 and 13 of the 7 housing. The cores of the mains lines and of the 8 connections 39 between the circuit lines and the conducting 9 contact rails 26 in the individual channels 25 that are combined into continuous conductors by bridging wires 37 are 11 connected by securing the lines 26 or connections 29 that 12 extend through the cover 27 over the conducting-strip holders 13 24 and into clips 40 that constitute a component of 14 conducting contact rails 26 generally in an area of the installation system adjacent to one of the ends. The 16 installation system, accordingly wired and provided with a 17 mounting lid 31, is then mounted below or on the plaster.
18 The installation equipment is then secured in its individual 19 installation areas by way of connecting lines 41 in accordance with the wiring diagram. The securing can be 21 carried out with pole shoes on the connecting lines or by 22 extending the insulated connecting lines 41 through 23 perforations 29 as far as conducting contact rails 26.
24 Connecting lines 41 themselves extend through perforations 29 introduced in the cover 27 over conducting-strip holders 24 26 for use as part of the still free clips 40 that constitute 27 conductors. The installation equipment, connected and 28 introduced into the housing, which rests, once it has been 29 introduced into housing 9, on the supporting ring 34 and 35 on mounting lid 31, is then connected to the lid by screws 20~048~
1 36.
3 All of the electric linkages undertaken in the installation 4 system can also be modified directly on the installed system without much expenditure when necessary. The conductor 6 sections embedded in the recesses can also be replaced by 7 correspondingly different conductor sections, for 8 communications systems for example. In so doing it is 9 necessary to observe the prevailing regulations of the individual certifying institutions, especially with respect 11 to the distances between conductors and to the appropriate 12 contact pressure. These measures in accordance with the 13 invention make the overall system very flexible and provide 14 the electrician with substantially more room to work in.
