Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0019] An embodiment of the disclosure is illustrated in the drawings and will be explained in more detail below. In the drawings:

[0020] FIG. 1 shows a perspective illustration of a heavy-duty plug connector with an inventive plug connector housing;

[0021] FIG. 2 shows a sectional partial view of the plug connector housing in the region of the cable outlet piece;

[0022] FIG. 3 shows a sectional perspective plan view of the inventive plug connector housing; and

[0023] FIG. 4 shows an exploded drawing of a detail of the inventive plug connector housing.

[0024] The figures may contain partially simplified, schematic illustrations. Identical reference signs are sometimes used for similar, but possibly not identical, elements. Different views of similar elements may be drawn to different scales. Directional information, for example “left,” “right,” “up” and “down” are to be understood in relation to the respective figure and may vary with respect to the object shown in the individual illustrations.

DETAILED DESCRIPTION

[0025] FIG. 1 shows a perspective illustration of a heavy-duty plug connector with an inventive plug connector housing 1. The plug connector is inserted into a so-called mounting flange 2. Such a mounting flange 2 is located for example on a device wall (not shown) and is secured thereto via screw openings 3.

[0026] To fasten the plug connection, the mounting flange 2 has two pivotable locking clips 4, which are laterally mounted on narrow sides of the mounting flange 2 and reach over respective locking pins (not shown) of the plug connector housing 1.

[0027] The plug connector housing 1 has a cable outlet piece 5, on which a cable gland 6 for fastening and strain-relief of the connected cable 7 is located at a cable outlet end.

[0028] It can be seen in FIG. 2, for example, that the cable outlet piece 5 substantially has the form of an angled cylinder. This means that the cable outlet piece 5 firstly extends linearly in a cable outlet direction of the plug connector housing 1 and then bends in a direction which deviates therefrom. With continued reference to FIG. 2, the cable 7 exits the plug connector housing 1 firstly in the direction R1 and then subsequently bends in the direction R2. The direction vectors R1 and R2 include a bending angle α. The bending angle α may be between 140° and 90° in some embodiments.

[0029] The cable outlet piece 5 can be fastened on the cable through-opening 8 of the plug connector housing 1 and is mounted for rotation in a circumferential direction relative to the cable through-opening 8. The direction of rotation is denoted by the double-headed arrow 9 in FIG. 3.

[0030] The functional elements for the rotatability of the cable outlet piece 1 are explained with reference to FIG. 4. The cable through-opening 8 has a collar 10, which protrudes from the plug connector housing 1 and in which two opposing fastening openings 11 are integrally formed.

[0031] The cable outlet piece 5 has a circumferential groove 12 on an outside in the lower connection region of the cable outlet piece 5. A ring 13 is placed into this groove 12, wherein the friction coefficient between the surface of the groove 12 and the inside of the ring 13 is selected such that the ring 13 is mounted in the groove 12 for rotation in the circumferential direction. The cable outlet piece 5 latches with the plug connector housing 1 in the direction of the arrow 17.

[0032] The ring 13 has two opposing, radially protruding fastening studs 14. However, for illustrative purposes, only one fastening stud 14 can be seen in FIG. 4. The fastening studs 14 each engage in a respective fastening opening 11, whereby the cable outlet piece 5 is fastened on the cable through-opening 8 of the plug connector housing 1. As a result of the rotatability of the ring 13, the entire cable outlet piece 5 is mounted on the cable through-opening 8 of the plug connector housing 1 for rotation in the direction of the double-headed arrow 9 (circumferential direction).

[0033] Two opposing internal steps 15 are provided in the cable through-opening 8. The fastening opening 11 is incorporated in these steps 15. The cable outlet piece 5 has two opposing, axially protruding fastening studs 16 on an outside of the cable outlet piece 5. Upon the rotation of the cable outlet piece 5, the lugs 16 of the cable outlet piece 5 are rotated towards a respective step 15 of the cable through-opening 8, whereby a rotation limit is realized. A rotation limit is needed in particular so that the connected cable 7 is not subject to too great a torsion, whereby it might become damaged.

[0034] FIG. 3 shows the rotation angle β through which the cable outlet piece 5 can be rotated relative to the plug connector housing 1 or to the cable through-opening 8. It has been shown that an angle β between 120° and 60° is sufficient.

[0035] Even where combinations of different aspects or features of embodiments of the invention are shown in the figures in each case, it is clear to a person skilled in the art—unless indicated otherwise—that the combinations shown and discussed are not the only possible combinations. In particular, mutually corresponding units or feature complexes from different embodiments may be interchanged with each other. Put another way, aspects of the various embodiments described above can be combined to provide further embodiments.

[0036] In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
