PLUG CONNECTOR HAVING A PLUGGING POSITIONING MEANS

Abstract

A plug connector has a cylindrical housing body having at least one step, which forms two different regions each having different housing diameters, wherein the region having the smaller diameter is designed as a plug-in region and the region having the larger diameter is designed as a socket region, wherein the plug connector has a lock, which is captively connected to the housing body, wherein the plug connector has an actuator, which is operatively connected to the lock, wherein the plug connector has a plugging positioner, which at least partially surrounds the plug-in region. An attachment flange fits the plug connector and has an insertion region designed as a hollow cylinder, wherein the inner region of the hollow cylinder has at least one step, which forms two different regions each having different inside diameters, wherein the inner region of the insertion region is unthreaded.

Description

EXEMPLARY EMBODIMENT

[0019] An exemplary embodiment of the invention is illustrated in the drawings and is further explained hereinunder.

[0020] In the drawings:

[0021] FIG. 1 illustrates a sectional view of a system comprising a mounting flange and a plug connector,

[0022] FIG. 2 illustrates a side view of a housing body of the plug connector,

[0023] FIG. 3 illustrates a perspective view of a locking means of the plug connector,

[0024] FIG. 4 illustrates a perspective view of a positioning means of the plug connector,

[0025] FIG. 5 illustrates a perspective view of an actuating means of the plug connector and

[0026] FIG. 6 illustrates a perspective view of the mounting flange.

[0027] The figures include partially simplified, schematic illustrations. In part identical reference numerals are used for identical elements, but where appropriate also for non-identical elements. Various views of the same elements could be scaled differently.

[0028] FIG. 1 illustrates a sectional view of a system in accordance with the invention of a plug connector 1 that is plugged in a mounting flange 2. The mounting flange 2 is generally integrated into a device (not illustrated).

[0029] The plug connector 1 comprises a locking means 3 that is fastened by way of a resilient ring 4 on the housing body 5 of the plug connector 1. Moreover, the plug connector 1 comprises a plug positioning means 6 that is arranged between the housing body 5 and the locking means 3.

[0030] The plug positioning means 6 includes three circumferential grooves, wherein two grooves 7, 8 are arranged on the interior or are oriented inwards and one groove 9 is oriented outwards. Sealing rings 10 are arranged in the respective grooves. The sealing rings 10 in the inner grooves 7, 8 seal the plug connector 1 itself. The sealing ring 10 that is located in the outer groove 9 seals the system of mounting flange 2 and plug connector 1 in the plugged state.

[0031] The diameter of the plugging region 11 of the housing body 5 is enlarged using the plug positioning means 6 in such a manner that it is no longer possible to plug the plug connector 1 incorrectly into a mounting flange having an insertion region having an inner thread.

[0032] FIG. 2 illustrates the essentially cylindrical housing body 5 of the plug connector 1. A step forms two different regions 11, 12 in the front part, said regions having different diameters.

[0033] The region having the smaller diameter forms the plugging region 11. The plugging region 11 is at least partially inserted so as to plug into the mounting flange 2. The region having the larger diameter is referred to as the base region 12. The base region 12 comprises a circumferential groove 13 and the resilient ring 4 for fixing the locking means 3 is embedded in said circumferential groove. By way of example, electrical contact elements (not illustrated) are arranged in the housing body 5 and said electrical contact elements are connected to individual conductors (not illustrated) of a multicore cable (not illustrated).

[0034] FIG. 3 illustrates the locking means 3. The locking means 3 is embodied essentially from a hollow cylinder and axial slots that form locking arms 14 are integrated into said hollow cylinder. Latching hooks 15 that are oriented inwards are arranged on the ends of the locking arms 14.

[0035] FIG. 5 illustrates a perspective view of the actuating means 16. The actuating means 16 comprises the base region 11 and the plugging region 12 of the housing body 5 and is in operative contact with the locking means 3. The actuating means 16 is configured essentially as a hollow cylinder. On one side, the edge of the hollow cylinder is turned over, as a result of which a collar is formed that is oriented into the interior of the hollow cylinder. The free collar end 17 acts upon inclined flank of the latching hook 15 when pulling back the actuating means 16 in the direction of the arrow 18 and presses the locking arms as a consequence radially outwards. The latching hooks 15 are removed from a groove 19 that extends around the mounting flange so that the plug connector 1 can be pulled out of the mounting flange 2. When plugging the plug connector 1 into the mounting flange 2, the latching hooks 15 initially slide along on the hollow cylinder 20 of the mounting flange before said latching hooks latch into the groove 19.

[0036] FIG. 6 illustrates a perspective view of the mounting flange 2. The mounting flange forms a hollow cylinder 20. The hollow cylinder comprises on the outside a groove 19 and, as mentioned above, latching hooks 15 of the locking arms 14 can engage in said groove. A step is illustrated in the inner region of the hollow cylinder 20, said step forming regions having a different diameter. The region having the larger diameter forms the so-called insertion region 21. The insertion region 21 is configured as threadless while the region that extends further downwards having the smaller diameter comprises a thread (not illustrated).

[0037] The invention relates to a plug connector (1) that is embodied from a cylindrical housing body (5) that comprises at least one step that forms two different regions (11, 12) having different housing diameters, wherein the region having the smaller diameter is configured as a plugging region (11) and the region having the larger diameter is configured as a base region (12), wherein the plug connector (1) comprises a locking means (3) that is connected in a loss-proof manner to the housing body (5), wherein the plug connector (1) comprises an actuating means (16) that is operatively connected to the locking means (3), wherein the plug connector (1) comprises a plug positioning means (6) that at least in part comprises the plugging region (11).

[0038] The invention likewise relates to a mounting flange that matches the plug connector, said mounting flange comprising an insertion region (20) that is configured as a hollow cylinder, wherein the inner region of the hollow cylinder comprises at least one step that forms two different regions having different inner diameters, wherein the inner region of the insertion region (20) is configured as threadless.
