The invention relates to a plug device with a housing socket.

Connector devices for electrical connections are well known.

From the DE 10 2013 113 878 A1 The next state of the art is a connector with single wire sealing.

From the US 2014 / 0 154 914 A1 A connector housing for a connector is known.

From the US 2011 / 0 075 971 A1 A sealing housing for a connector is known.

The invention is therefore based on the object of developing a plug device with a housing socket, whereby a long service life is to be achieved.

According to the invention, the object is achieved in the plug device according to the features specified in claim 1.

• - einen Fixierbereich,
• - einen Auslaufbereich,
• - einen Verzahnungsbereich und
• - einen konischen Bereich

aufweist,
wobei die Gehäusebuchse ein Innenschraubgewinde aufweist,
wobei, insbeosndere in einem Teilbereich der gesamten axialen Länge der axialen Länge der Gehäusebuchse, der maximale Außendurchmesser der Gehäusebuchse in axialer Richtung, insbesondere vom Fixierbereich über den Auslaufbereich, den Verzahnungsbereich und den konischen Bereich, monoton, insbesondere streng monoton, zunimmt,
insbesondere wobei die axiale Richtung parallel zur Schraubachse des Innenschraubgewindes ausgerichtet ist.Important features of the invention in the plug device are that the plug device is designed with a housing socket, wherein the housing socket

• - a fixation area,
• - a run-off area,
• - a gearing area and
• - a conical area

has,
wherein the housing bushing has an internal screw thread,
wherein, in particular in a partial area of the total axial length of the axial length of the housing bush, the maximum outer diameter of the housing bush increases monotonically, in particular strictly monotonically, in the axial direction, in particular from the fixing area via the run-out area, the toothing area and the conical area,
in particular wherein the axial direction is aligned parallel to the screw axis of the internal screw thread.

The advantage here is that liquids cannot accumulate, thus preventing corrosion. This increases the service life. Since a plug insert can be screwed into the internal screw thread, the penetration of liquid into the interior of the housing socket can be prevented.

Preferably, the sub-area comprises the fixing area, the run-out area, the toothing area and the conical area.

In an advantageous embodiment, the housing bushing is formed in one piece, in particular in one part. The advantage here is that it is easy to manufacture and is sealed against the ingress of liquids.

In an advantageous embodiment, the fixing area borders on the outlet area in the axial direction,
wherein the run-out area is adjacent to the toothing area in the axial direction,
The toothed area is adjacent to the conical area in the axial direction. The advantage here is that there are no axial gaps between the areas and thus the drainage of liquid can be reliably guaranteed.

In an advantageous embodiment, a chamfer rounding area borders the conical area in the axial direction at the axial end of the conical area facing away from the toothing area. The advantage here is that sharp edges are avoided and thus damage that leads to corrosion can be prevented.

In an advantageous design, the maximum outer diameter of the chamfer rounding area decreases strictly monotonically with increasing axial distance from the conical area. The advantage here is that liquids flow away safely.

In an advantageous embodiment, the radial wall thickness of the conical area is greater than the radial wall thickness of the toothed area. The advantage here is that increased stability can be provided and thus a secure, stable and correspondingly tight connection with the plug insert can be provided. In particular, the plug insert can be connected to the housing socket in a tight and stable manner.

In an advantageous embodiment, the area covered by the internal screw thread in the axial direction overlaps with the area covered by the toothed area in the axial direction and with the area covered by the conical area in the axial direction. The advantage here is that although the cutting of the internal screw thread weakens the housing wall of the housing bush, the thickening in the conical area results in increased rigidity.

In an advantageous embodiment, a toothing is formed on the outer circumference of the housing bush, in particular the toothing area,
in particular, the teeth of the gearing extend in the axial direction. The advantage here is that an increased torque can be introduced when holding.

In an advantageous embodiment, the housing bushing is made of metal. The advantage here is that the housing bushing can be made robust and thus a long service life can be achieved.

In an advantageous embodiment, the radial depth of the tooth gaps of the gearing decreases monotonically, in particular strictly monotonically, in the run-out area with increasing distance from the gearing area. The advantage here is that the accumulation of liquids is prevented.

In an advantageous embodiment, the fixing region has a greater extent in a first direction than in a second direction perpendicular to the first direction,
wherein the first direction and the second direction are each aligned perpendicular to the axial direction. The advantage here is that increased rigidity can be achieved, particularly at the end of the housing bushing opposite the conical region.

In an advantageous embodiment, the fixing area has a continuous recess through which a cable protrudes, onto which a cable grommet is attached,
in particular, the cable grommet protrudes into the continuous recess. The advantage here is that the cable protrudes through the fixing area and can be connected to the fixing area in a force-fitting manner. In particular, the cable can be squashed and/or deformed with a pin and can therefore be connected to the housing socket in a force-fitting manner.

In an advantageous embodiment, the plug device has a plug insert which has a first screw thread and a second screw thread spaced apart therefrom in the axial direction,
where the first screw thread is screwed into the internal screw thread,
wherein the wires of the cable are integrally connected, in particular soldered, to connection pins projecting axially from the plug insert,
in particular wherein the screw axis of the first screw thread is aligned coaxially to the screw axis of the second screw thread and/or is aligned parallel to the axial direction.

In an advantageous embodiment, the plug insert has an external hexagon area which is arranged axially between the first and the second screw thread. The advantage here is that a high torque can be introduced to connect the plug insert to the housing socket and thus a secure connection can be achieved.

In an advantageous embodiment, the radially outer circumference of the fixing region adjacent to the front side of the outlet region is shaped like a cuboid, the longest edges of which extend parallel to the first direction and at the end region of which, viewed in the first direction, a first rounded region is adjacent and at the end region of which, viewed opposite to the first direction, a second rounded region is adjacent,
wherein the first rounded area is mirror-symmetrical to the second rounded area,
in particular, each of the rounded areas has a respective cylinder surface area on its outer surface. The advantage here is that the housing bushing is stiffened by the non-circular design of the fixing area and thus a higher overall stiffness can be achieved.

Further advantages arise from the subclaims. The invention is not limited to the combination of features in the claims. The person skilled in the art will recognize further useful combination options of claims and/or individual claim features and/or features of the description and/or the figures, in particular from the task and/or the task arising from comparison with the prior art.

• In der 1 ist die erfindungsgemäße Steckervorrichtung explodiert dargestellt, welche eine Gehäusebuchse 5 aufweist.
• In der 2 ist die Gehäusebuchse 5 in Schrägansicht dargestellt.
• In der 3 ist die Gehäusebuchse 5 in Seitenansicht dargestellt.
• In der 4 ist eine Schnittansicht der Gehäusebuchse 5 dargestellt.

The invention will now be explained in more detail using schematic illustrations:

• In the 1 the plug device according to the invention is shown exploded, which has a housing socket 5.
• In the 2 the housing socket 5 is shown in an oblique view.
• In the 3 the housing socket 5 is shown in side view.
• In the 4 a sectional view of the housing socket 5 is shown.

As shown in the figures, the plug device has a housing socket 5 which has an internal screw thread 40 into which a first screw thread 3, in particular an external thread, of a plug insert 11 can be screwed.

The plug insert 11 has axially projecting connection pins 4 at its first axial end region, to which the wires of a Cable are firmly connected. The cable 12 extends through a recess in the housing socket 5 to the connection pins 4.

The axial direction is parallel to the screw axis of the first screw thread 3.

A cable grommet 7 is placed on the cable 12, which protrudes into a fixing area 6 of the housing socket 5 and is connected in a force-fitting manner by means of a retaining pin 13, in particular a threaded pin. The cable 12 is thus held in a force-fitting manner in a fixing area 6 of the housing socket 5.

In the axial direction, a run-out area 8 borders on the fixing area 6. A toothing area 9 borders on the axial end of the run-out area 8 facing away from the fixing area 6. A conical area 10 borders on the axial end of the toothing area 9 facing away from the run-out area 8, at whose axial end facing away from the toothing area 9 a chamfer rounding area is arranged.

The housing bushing 5 has an outer diameter that increases monotonically, in particular strictly monotonically, in the axial direction from the fixing area 6 via the outlet area 8 and the toothing area 9 as well as the conical area 10. This ensures that liquids are optimally drained away in any assembly direction.

The teeth of the toothing incorporated in the toothing region 9 extend in the axial direction, wherein the teeth and/or the tooth gaps arranged in the circumferential direction between the teeth run out in the run-out region 8, in particular thus being cut less and less deeply into the housing bushing 5 with increasing distance from the toothing region 9.

The fixing region 6 is designed to be non-circular. For this purpose, the fixing region 6 has a greater extent in a first direction than in a second direction perpendicular to the first direction, wherein the first direction and the second direction are aligned perpendicular to the axial direction.

The outer circumference of the fixing region 6 adjacent to the front side of the outlet region 8 corresponds to a cuboid whose longest edges extend parallel to the first direction and whose two end regions, viewed in the first direction, each have a rounded region. In particular, each of the rounded regions has a cylinder surface area on its outer surface.

The plug insert 11 has not only the first screw thread 3, but also a second screw thread 3 which is spaced apart in the axial direction from the first screw thread 3 and to which a mating connector can be screw-connected.

In addition, a hexagonal region 1 is arranged axially between the first screw thread 3 and the second screw thread 2, so that a torque can be derived by means of a tool, in particular an open-end wrench.

As in 4 As shown, the area covered by the internal screw thread 40 of the housing bushing 5 in the axial direction overlaps both the area covered by the toothed area 9 in the axial direction and the area covered by the conical area 10 in the axial direction.

The radial wall thickness of the conical area 10 is greater than the radial wall thickness of the toothing area 9.

The housing socket 5 is made of a metal, in particular steel.

In further embodiments according to the invention, the housing bushing 5 is made of plastic.
