Definitions
- the present invention relates to a cable or tube entry, preferably arranged in an electrical junction box intended for outside installation e.g. on a wall. Cables or tubes withholding cables are also intended for laying on the outside of the wall and into the junction box. BACKGROUND TECHNICS
- junction boxes for outside installation show a bottom provided with a surrounding rim in which the entries are arranged mainly in the middle of the rim and located in some distance from the bottom of the box.
- a disadvantage with that location of the entries is that cables intended to be laid outside e.g. a wall and into the junction box have to be bent from the wall in order to get introduced into the box. That is time-consuming and sometimes even aesthetically less attractive.
- junction boxes have been developed in which the entry holes have been placed closest to the bottom of the box. Such a junction box is described in the Swedish patent application SE 396 165.
- the entry holes also may show elastic membranes intended to be penetrated with the cables and then give a tightening between box and cables.
- the cable and tube entry according to the invention may e.g. be arranged in an electrical junction box that shows a bottom provided with a surrounding rim, the mentioned entry being arranged in the rim or similar means closest to the bottom and shows an elastic membrane intended to be penetrated with a cable or a tube .
- the elastic membrane shows an eccentrically arranged notch for the penetration located closest to the bottom of the box which admits that even cables with a considerable smaller diameter then the diameter of the entry hole may be introduced through the membrane without needing be bent from a ground as e.g. a wall on which the cables are visibly laid.
- Figure 1 shows a junction box provided with entries according to the invention in a vertical sectional view.
- Figure 2 shows the junction box according to figure 1 seen from above.
- Figure 3 shows the junction box according to figure 1 seen in a perspective diagonally from above.
- Figure 4 shows a vertical section through an entry along line I-I in figure 1.
- the junction box that is shown in figures 1-3 comprises a box 1 showing a square bottom 1.1 with a surrounding rim 1.2.
- the box 1 is covered with a slightly curved cap 2.
- the rim 1.2 shows different kinds of entries which all comes within the scope of the invention.
- a first type of entry consists of a circular hole 3 in which an elastic plug provided with a snap- in locking is intended to be affixed, the plug itself showing a membrane with a notch for penetration with e.g. a cable .
- a second type of entry consists of a circular elastic membrane 4, which is a part of the rim 1.2 and which is provided with a centrally arranged notch 4.1 for penetration with e.g. a cable.
- the rim 1.2 then is made of partly an interior elastic layer, partly a hard exterior layer provided with circular holes in which the interior layer stands out and constitutes a membrane 4.
- a third type of entry consists of a circular elastic membrane 5, which is a part of the rim 1.2 like the entry 3 mentioned before, but which is provided with an eccentrically arranged notch 5.1, located at the lower edge of the entry.
- Figure 4 shows a cross-section of the eccentric membrane 5 that shows the notch 5.1 for the cable entry located nearest to the bottom 1.1 of the box 1.
- the electric wires that are laid upon the wall may be laid into the junction box without needing be bent.
- the eccentric membrane 5 with the notches 5.1 placed closest to the bottom 1.1 of the box 1 even cables with a considerable smaller diameter than the entry hole may be laid into the box without needing be bent, as the membrane 5 may be penetrated closest to the bottom 1.1 of the box 1.
