  • the sealing block can take over the stringing of two junction boxes of this type.
  • Its design is preferably such that it has a first retaining web, a first connecting groove, a contact web, a second connecting groove and a second retaining web all around in the direction of the cable bushings, that the cross section of the contact web corresponds to the cross section of the assembled end wall of the lower housing part and cover and the width of the connecting grooves corresponds to the same wall thickness of the end walls of the lower housing part and cover, that the cross section of the sealing block in the region of the connecting grooves corresponds to the cross section of the composite insertion opening of the lower housing part and cover, and that the cross section of the retaining webs corresponds to the cross section of the combined receiving groove of the lower housing part and Cover and the thickness of the retaining webs correspond to the width of the receiving groove of the lower housing part and cover.
  • the juxtaposition of device connection boxes in the area of the side walls is achieved according to one embodiment in that in the side walls of the lower housing part and cover aligned semicircular, break-out wall parts are provided which form round insertion openings for cable with closed cover and that in these insertion openings with a circumferential external groove provided cable sleeves can be used.
  • the cable grommets take over the connection of adjacent device connection boxes.
  • the design is such that the outer groove of the cable grommets has a width that corresponds to twice the same wall thickness of the lower housing part and cover, and that the cross section of the cable grommets in the area of the outer groove corresponds to the cross section of the composite insertion opening.
  • the fastening screws for fastening the cover to the lower housing part are arranged in recessed receptacles with latching elements which are introduced into the four corner regions of the cover plate of the cover, and that the receptacles can be closed by means of closure lids which can be closed by means of Film hinge formed on the lid and can be snapped into the receptacles provided with locking elements in a closed position flush with the cover plate, then these connection points between the lid and the lower housing part are also covered tightly.
  • one embodiment provides that the cable bushings in the sealing block are closed by means of break-out plugs.
  • one embodiment provides that the box-like cover in the central region of the cover plate has a shoulder extending beyond the end walls to form an enlarged cover chamber, or that the box-like cover has the sealing blocks protrudes on the end walls and forms an enlarged cover chamber over the entire lower housing part.
  • the lower housing part 10 shown in FIG. 1 is box-shaped with the side walls 11, the end walls 14 and the bottom.
  • the terminal strip 50 is arranged between the two side walls 11 and is preferably connected to the bottom of the lower housing part 10.
  • the connections on the Terminal block 50 can be designed as solder, clamp or screw connections.
  • the end walls 14 of the lower housing part 10 are recessed towards the parting plane of the junction box with the cover 20 according to FIG. 2 and form the part 15 of a single insertion opening, which is completed with the part 25 of the end wall 24 of the cover 20.
  • the insertion openings of the two assembled end walls 14 and 24 of the junction box assembled in this way extend practically over the entire width of the end walls 14 and 24.
  • receiving grooves 16 are formed Immediately following the end walls 14 and 24 of the lower housing part 10 and cover 20, receiving grooves 16 are formed. Molded shoulders 17, which divide cable entries 37, adjoin these receiving grooves 16 in the lower housing part 10. The upper sides of the lugs 17 carry 18 blind holes as fastening points.
  • the strain relief clamps 19 can be screwed tight onto these projections 17, self-tapping screws preferably being used which cut the thread into the blind holes in the plastic housing lower part 10. The strain relief clamps 19 fix the cable in the cable entries 37.
  • wall parts 12 which can be broken out and are aligned with one another are provided, which open a semicircular insertion opening 13 and 23, respectively. If the cover 20 is connected to the lower housing part 10, the semicircular insertion openings are supplemented to round insertion openings.
