Description

(1) The invention is explained in detail with reference to the following Figures. In the drawings:

(2) FIG. 1 shows a perspective view of an embodiment of a junction box with a base part and a cover part arranged pivotably on the base part, with the cover part in an open position and with a locking element in an intermediate position;

(3) FIG. 2 shows the junction box according to FIG. 1 with the locking element in a first position;

(4) FIG. 3 shows an enlarged detail from FIG. 1;

(5) FIG. 4 shows a section through the junction box according to FIG. 1 with the locking element in the intermediate position;

(6) FIG. 5 shows a section through the junction box according to FIG. 1 with the cover in a closed position;

(7) FIG. 6 shows a section through the junction box according to FIG. 2 with the locking element in the first position; and

(8) FIG. 7 shows a further section through the junction box according to FIG. 2 with the locking element in the first position.

(9) FIGS. 1 to 7 show different views of a junction box 10 with a base part 20 and a cover part 30 arranged on the base part 20, in particular so as to be pivotable about a pivot axis A.

(10) The junction box 20 can be designed as an electrical or optical junction box. For this purpose, the junction box 20 can on the one hand have corresponding openings 12 in the base part 20 and/or cover part 30, through which connected cables can be led out of the junction box 20. Furthermore, openings 14 can be arranged, in particular in the base part 20, through which fixing means can be guided, in particular screws 80 (cf. FIG. 7), for fastening the junction box 20 to a wall. It is possible to make the junction box 20 lockable, for example through two corresponding openings 16a, 16b, of which one opening 16a can be arranged in the base part 20 and the other opening 16b in the cover part 30 and through which the shackle of a U-lock can for example be guided.

(11) A spring element 40 is arranged between the base part 20 and the cover part 30. The spring element 40 is designed in such a way that it transfers the cover part 30 from an open position (see FIG. 1) to a closed position (see FIG. 5), provided there is no force counteracting the spring force of the spring element 40. The cover part 30 can be transferred against the spring force of the spring element 40 from the closed position to the open position. The spring element 40 can for example be arranged as a helical spring around the pivot axis A between the base part 20 and the cover part 30 and be supported on one end on the base part 20 and on the other end on the cover part 30.

(12) In order to be able to lock the cover part 30 in the open position, a locking element 50 is provided, which is mounted so as to be movable between a first position (see FIG. 2) and a second position (see FIG. 5), in particular via an intermediate position (see FIG. 1), in particular pivotable about a pivot axis B. The locking element 50 can be arranged on the outside of the junction box 20, but is preferably arranged inside the junction box 20. In the first position, the locking element 50 locks the cover part 30 against the spring force of the spring element 40 in the open position. In the second position, the locking element 50 allows the cover part 30 to be transferred from the open position to the closed position.

(13) The locking element 50 can be designed as a lever 51 with a first end 51a and a second end 51b, the lever 51 being pivotably mounted at its first end 51a on the junction box 10 and having a contact element 52 at its second end 51b, which can for example be designed as a cross bar. The contact element 52 comes to rest on a stop surface 71 in the first position. The stop surface 71 can for example be formed on the base part 20, while the lever 51 can be pivotably mounted on the cover part 30. Of course, the arrangement can also be reversed. In the first position, the locking element 50 is arranged in such a way that it prevents the cover part 30 from snapping shut onto the base part 20. For example, the locking element 50 is set up for this purpose in such a way that its one end 51a rests in particular in a stationary manner on the cover part 30, for example due to the pivotable mounting, while its other end 51b rests in particular in a stationary manner on the base part, for example through bringing the contact element 52 in contact with the stop surface 71, so that the cover part 30 is kept at a distance from the base part 20 (see in particular FIG. 6).

(14) The stop surface 71 can be formed on a bar 70. There can also be two bars 70 arranged parallel to one another, each with a stop surface 71, which can facilitate the detachment of the contact element 52 from the stop surfaces 71.

(15) A second latching mechanism 72 can be provided, which fixes the positioning of the contact element 52 on the stop surface 71. The stop surface 71 can for example be arranged inclined relative to the base surface of the base part 20 for this purpose, so that a slight undercut is formed, in which the contact element 52 can be secured against inadvertent detachment from the stop surface 71.

(16) In order to be able to close the cover part 30, the locking element 50 is transferred to the second position, in particular pivoted. For this purpose, the locking element 50 can, for example, be pivoted in such a way that it rests approximately on the inside of the cover part 30 (see FIG. 5). In this position, the cover part 30 can be transferred from the open position to the closed position, in particular without being impaired by the locking element 50.

(17) A first latching mechanism 60 can be provided, which fixes the positioning of the locking element 50 on the cover part 30 in the second position. For this purpose, two pins 61 can for example be arranged parallel to and at a distance from one another on the cover part 30, between which the lever 51 of the locking element 50 can be guided. A latching projection 62, which fixes the locking element 50 between the two pins 61 in a latching manner, can be arranged on each of the surfaces of the pins 61 facing one another.

(18) In order to be able to easily grip the locking element 50, a first handle 53 for transferring the locking element 50 from the first position to the second position and/or a second handle 54 for transferring the locking element 50 from the second position to the first position can be formed on the locking element 50, in particular on the lever 51. The first handle 53 and/or the second handle 54 can be designed as a cross bar on the locking element 50, in particular the lever 51.
