Description

[0001] The invention relates to a connector system with a plug part and a mating connector with at least two locking lugs for forming a quick-disconnect connection of the plug part with the corresponding mating connector, wherein the plug part comprises at least one plug part housing which is primarily sleeve-shaped and has a preferred longitudinal axis, and the plug part has, at least in an area around a first end side, which is a plug-side end side, at least one locking latch for the locking lugs of the mating connector, which locking latch is effective at least in an axial direction along the preferred longitudinal axis, wherein the longitudinal extent of the at least one locking latch is limited parallel to the preferred longitudinal axis by at least one primary flank and at least one secondary flank,wherein the primary flank and the secondary flank are arranged opposite one another, and the primary flank delimits the latching catch counter to the plug-in direction and the secondary flank delimits the latching catch in the plug-in direction, wherein the latching catch is formed at a transition from the plug-part housing to a plug-part adapter arranged on the plug-side of the plug-part housing in such a way that the primary flank is arranged on the plug-part adapter and the secondary flank is arranged on the plug-part housing, or both the primary flank and the secondary flank are arranged on the plug-part adapter, wherein the primary flank is designed as a stop for the locking lugs of the mating connector, acting counter to the plug-in direction.

[0002] A corresponding connector system is known, for example, from WO 2017 / 030573 A1, DE 295 17 358 U1, US 2005 / 202706 A1, and US 2008 / 108242 A1. WO 2020 / 119854 A1 discloses a connector system with a plug part comprising a plug part housing that forms a latch and an internal thread.

[0003] The invention lies in the field of connector technology, in particular in the field of circular connectors, with known designs of corresponding connectors with an M12, M8, M23 or 7 / 8" thread being mentioned as examples. Such (circular) connectors and corresponding mating connectors are used to enable power and / or signal transmission when the connector and the respective corresponding mating connector are appropriately connected to one another. For this purpose, both the connector and the mating connector can be arranged on the connection side, for example, at the ends of two power and / or signal-carrying cables, wherein the cables can be connected or connected to one another in a power and / or signal-carrying manner by means of the connector and mating connector on the plug side. Alternatively, however, the connector in particular could also be connected on the connection side to a circuit board, printed circuit board or the like.The connector can have one or more socket contacts as inward-facing ("female") contact openings as well as one or more outward-facing ("male") contact pins; the mating contacts of the corresponding mating connector have correspondingly designed contact pins or socket contacts. Circular connectors and the corresponding mating connectors are often screwed together, creating a stable and resilient connection that can withstand, for example, mechanical stress from connected machines (i.e., the connector is arranged on / in a machine or device housing). However, the manufacture of screw connections between the connector and the mating connector is complex, and the connector and mating connector must have correspondingly matched threads.

[0004] A less complex alternative to a screw connection between a connector and a mating connector is a quick-disconnect connection, generally better known by the English term "push-pull" connection. The mating connector, for example, has locking means in the form of locking lugs or locking hooks on elastic extensions, locking arms, or the like, which extend primarily axially in the plugging direction and project particularly radially relative to the plugging direction. These locking lugs or hooks can engage and lock into one or more locking catches, locking pockets, or the like formed on the connector.When defining the plug-in direction, it is assumed here, without loss of generality, that the connector is at rest and that the corresponding mating connector, to form a plug-in connection between the connector and the mating connector, is moved in a straight line with the plug-side end face toward the plug-side end face of the connector until the locking means of the mating connector fully engage and lock into the latch(es) of the plug part. Latching latches or latching pockets are designed as recesses in a connector housing part of the connector that are primarily radial to the plug-in direction and have flanks that are spaced apart from one another in the axial direction parallel to the plug-in direction and that delimit the latch or latching pocket in the axial direction. In particular, the first flank that is closer to the plug-side end face of the connector is designed as a stop for a latching nose or latching hook.The second, spaced-apart flank, which is further away from the plug-side end of the connector, can be designed as a stop for a locking lug or locking hook in the plug-in direction, but this is not mandatory. Other stops that act in the plug-in direction and do not directly affect the locking lugs or locking hooks in particular, or the locking means in general, can also be provided, limiting the relative movement of the mating connector to the connector in the plug-in direction.When forming a connection between the connector and the mating connector, the relative movement of the mating connector to the connector in the plug-in direction should only be limited when the locking lugs or locking hooks are (fully) engaged with the corresponding locking catches or locking hooks, and a relative movement counter to the plug-in direction, which would separate the connector and the mating connector, is prevented accordingly. A separation of the connection between the connector and the mating connector, or a relative movement of the connector and the mating connector counter to the plug-in direction, is then only possible again - without destructive external intervention - when the locking lugs or locking hooks are disengaged from the corresponding locking catches or locking pockets due to a corresponding deflection in the radial direction.This assumes that the locking latches or locking pockets on the connector and the locking means are designed to engage the locking pockets on the corresponding mating connector. In principle, a reverse assignment is also possible.

[0005] Connectors are known from the prior art in which both a thread for forming a screw connection with a corresponding mating connector and locking catches or locking pockets are provided for forming a quick-disconnect connection with a corresponding mating connector. The respective mating connector then has either a corresponding thread for forming a screw connection with the connector or corresponding locking means for forming a quick-disconnect connection with the connector. The locking catches or locking pockets are arranged on an inner wall in the vicinity of the plug-side end of a connector housing part, which for circular connectors is typically primarily sleeve-shaped, at least in the vicinity of a plug-side end of the connector.An internal thread for forming a screw connection is arranged at a greater distance from the plug-side end face on an inner wall of the connector housing part - compared to the arrangement of the locking latches or locking pockets - and thus, in the plug-in direction, somewhat deeper inside the connector housing part.

[0006] While the combination of two different means for forming a detachable connection with a mating connector in a (circular) connector may be advantageous, this design also has significant disadvantages. To ensure that an (external) screw thread of a mating connector, which is designed to create a screw connection with such a connector, can smoothly engage the connector housing portion of the connector to establish the screw connection at the plug-side end, all parts of the inner wall of the connector housing that lie between the internal thread and the plug-side end of the connector must have a larger radius than the portion of the inner wall of the connector housing portion in the area of ​​the internal thread due to the locking catches or locking lugs arranged on an inner wall of the connector housing in front of the internal thread in the plug-in direction.Taking into account a certain depth of the locking latches or locking pockets formed as recesses, depressions or the like in an inner wall of the connector housing part and the fact that the connector housing part should be stable in this area even under load, it is obvious that it is difficult to avoid that the outer circumference or the outer diameter of the connector housing part in the area of ​​the locking pockets must be larger than in the area of ​​the external thread.This can lead to the problem that such a connector is too large, in particular in terms of diameter, for recesses, feedthroughs or the like in device housings, machine housings or the like, where such a connector is to be used for external contact and at least one plug-side end region has to be passed through a recess, feedthrough or the like, whereby these recesses, feedthroughs or the like are, however, only adapted to the smaller diameter of known and / or standardized connectors, which are typically designed only to produce a screw connection with a mating connector.

[0007] Based on the described disadvantages of the prior art, the invention is therefore based on the object of proposing a connector system that is simple and cost-effective to manufacture and can be used within the existing limitations of standardized circular connectors and can easily replace the known standardized circular connectors.

[0008] The object is achieved according to the invention by a connector system according to claim 1. Further advantageous embodiments can be found in the dependent claims.

[0009] Accordingly, at least one internal thread is arranged on an inner wall of the plug part housing at a position located further inward along the preferred longitudinal axis on the plug side than the at least one latching catch and is designed to correspond to the external thread of a corresponding mating plug.

[0010] The flanks of the at least one latching catch, preferably formed as a recess, depression, or the like, extending primarily radially in a plug-side end region of the plug part, are, in a sense, the walls of the latching catch that delimit the recess, depression, or the like in the preferred longitudinal axis. The flanks are not necessarily arranged in a plane perpendicular to the preferred longitudinal axis; they can form at least an acute angle with such a plane. InIn this sense, the flanks can therefore be bevels. The flanks can also be designed as a three-dimensional free-form surface and / or segmented from at least two partial flanks, wherein the partial flanks can furthermore each enclose at least one acute angle to one another. The provision of the primary flank of a latching catch on the plug part adapter and the secondary flank on the plug part housing means that the latching catch is divided between these two components of a plug part of a plug connector system according to the invention at the deepest point of the latching catch designed as a recess, depression or the like. The primary flank and the secondary flank can directly adjoin one another at the deepest point of the recess, depression or the like.However, the deepest point can also be an extended area, so that the primary flank and the secondary flank are spaced apart, particularly in the axial direction along the preferred longitudinal axis of the plug housing. The deepest point extends in the axial direction parallel to the preferred longitudinal axis. If this were not the case, it would not be the deepest point of the locking latch formed as a recess, depression, or the like, but rather part of either the primary flank or the secondary flank.

[0011] Dividing the locking latch into two housing sections of the plug part, adjacent to each other along the preferred longitudinal axis, has the advantage that the plug part housing can be designed, particularly in terms of its outer diameter, to correspond to known standardized (circular) connectors. The increase in the diameter of the plug part required due to the provision of a locking latch for forming a quick-disconnect connection with a corresponding mating connector can then be limited to the plug part adapter.To stabilize the plug connector in the region of the at least one latch, the plug adapter preferably extends a short distance outward in the longitudinal direction and at the same time in the plug-in direction over and at least partially circumferentially around the plug-side end of the plug-in distribution housing part. In addition, it is particularly preferred that at least in this overlapping region of the plug adapter and plug housing it be fixed or fixable to the plug housing in a non-destructive or non-destructive manner. This means that the plug connector with its plug housing can initially be passed through a recess in a device housing or the like, through which the plug housing can be passed in terms of diameter, but for which the plug adapter is too large, and then the plug adapter can be arranged on the plug housing and fixed to the plug housing in a non-destructive or non-destructive manner.

[0012] For the production of such a plug part of a plug connector system according to the invention, the proposed solution for forming at least one latch at the transition from the plug connector housing part to the plug part adapter does not require the formation of an undercut. In the case of components that are produced using standard injection molding processes (plastic, zinc die-casting, etc.), such an undercut can only be demolded with considerable effort, or in the worst case not at all. This makes the production of such a plug part in an injection (pressure) molding process using conventional methods of demolding the workpiece, in particular without a slide, or using special demolding methods (foldable core, slide) significantly easier and more cost-effective. In addition, different materials or processes can be used to manufacture the plug housing and the plug part adapter.Material combinations are used, which requires an even better design of a connector of a connector system according to the invention in accordance with the intended use and the requirements placed on it.

[0013] If the at least one latching catch is formed entirely on the plug part adapter, i.e., the primary as well as the secondary flank of the latching catch formed as a recess, depression or the like are arranged on the plug part, the manufacturing advantage may be lost. However, the advantage that the connector housing part of the plug part of a connector system according to the invention can be formed, in particular with regard to the outer diameter, in accordance with known and / or standardized (round) connectors and that the increase in diameter caused by the provision of at least one latching catch for establishing a quick-disconnect connection with a corresponding mating connector can be shifted entirely into the plug part adapter, remains unchanged.

[0014] The plug part adapter can also be designed as part of a device housing, machine housing, or the like, into which a plug part of a connector system according to the invention can be or is installed. In a simple variant, the plug part adapter can then be a plate, for example, wherein the plug part or the plug part housing of the plug part and the plate can be or are fixed to one another non-destructively or detachably. This plate is preferably designed and arranged perpendicular to the preferred longitudinal axis at least in an area around the plug-side end of the plug part housing. The plate has a feedthrough for a corresponding mating connector at the point at which the plate and plug part housing are or can be arranged to one another with their plug-side end.This feedthrough is bordered by the plug-side end of the connector housing when the connector housing and plate are arranged and / or fixed together. In a common virtual (imaginary) inner wall of the plug part housing and the feedthrough, the at least one latching catch is then designed as a recess, depression or the like in such a way that the latching catch extends along the preferred longitudinal axis over the transition between the plug connector housing part and the plate, with the primary flank of the latching catch being arranged on the plate and the secondary flank on the plug part housing, and the transition between the plug connector housing part and the plate being located precisely in the region of the deepest point of the latching catch.

[0015] According to a preferred embodiment of a connector system according to the invention, the connector housing and the connector adapter can be connected or connected to one another in a non-destructively detachable manner, for example by means of a screw connection, a plug connection or a clamp connection.

[0016] In a preferred embodiment of a connector system according to the invention, it is provided that the connector housing and the connector adapter are connectable or connected to each other in a non-destructive manner, for example by means of an adhesive connection, a welded connection or by means of plastic deformation ("crimping").

[0017] A preferred embodiment of a connector system according to the invention comprises the formation of at least one latching catch on an inner wall of the connector housing part in an area surrounding the plug-side end side of the plug part.

[0018] According to a particularly preferred embodiment of a connector system according to the invention, the connector part housing and / or the connector part adapter is made of a plastic material.

[0019] In a particularly preferred embodiment of a connector system according to the invention, at least the connector adapter is made of a metal and / or a metal alloy. Various manufacturing processes are possible, for example, using casting processes such as injection molding, injection-molding, casting, and / or machining processes (milling, turning).

[0020] According to the invention, the connector system comprises the formation of at least one internal thread on an inner wall of the connector part housing, wherein the internal thread is arranged at a position further inward along the preferred longitudinal axis on the connector side than the at least one latching latch and is formed corresponding to the external thread of a corresponding mating connector.

[0021] What all designs have in common is that the locking latch is formed by the plug adapter rather than the plug housing, and in some cases, the desired locking connection is only achieved through the interaction of these parts. The aforementioned advantages in manufacturing and the load-bearing capacity of the parts are therefore always present.

[0022] The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respective combination specified, but also in other combinations or on their own.

In a simplified, schematic view, the drawings show: Fig. 1 shows the essential elements of a first embodiment of a connector system according to the invention in a three-dimensional isometric view; Fig. 2 shows a longitudinal sectional view of a first embodiment of a connector system according to the invention according to Figure 1 in the connected state; Fig. 3 shows a longitudinal sectional view of a second embodiment variant of a connector system according to the invention in the connected state; Fig. 4 shows a longitudinal sectional view of a third embodiment variant of a connector system according to the invention in the connected state; Fig. 5 shows a longitudinal sectional view of a fourth embodiment variant of a connector system according to the invention in the connected state; Fig. 6 shows a longitudinal sectional view of a fifth embodiment variant of a connector system according to the invention in the connected state; Fig. 7 shows a section A1 from the longitudinal sectional view of a connector system according to the invention in a first embodiment variant from Figure 2 with a greatly enlarged view of the latch and its immediate surroundings; Fig. 8 shows a longitudinal sectional representation of the plug part of a connector system according to the invention taken on its own in a first embodiment variant according to Figure 1as well as Figure 2 ; and Fig. 9 Section A2 from the longitudinal sectional view of the plug part of a plug connector system according to the invention in a first embodiment variant from Figure 8 with a greatly enlarged view of the latch and its immediate surroundings.

[0024] The Figures 1 to 6 show various design variants of a connector system 1 according to the invention. The designs differ only in certain details, but not fundamentally from one another. In Figure 1A first embodiment of a connector system 1 according to the invention is shown in a three-dimensional isometric view, wherein the essential elements of the connector system 1 are shown spaced apart from one another along a preferred longitudinal axis of the connector system 1. The connector system 1 consists of a plug part 2 and a corresponding mating connector 3. Both the plug part 2 and the mating connector 3 are designed to be substantially rotationally symmetrical about a preferred longitudinal axis. The plug part 2 has a predominantly sleeve-shaped plug part housing 4, in which a substantially cylindrical contact carrier 6 is arranged concentrically to the plug part housing 3, which socket contacts 15 (in Figure 1 not visible). In Figure 1Only the plug-side end of the contact carrier 6 is visible. The plug-side end of the plug part 2 is the end, more precisely the axial end of the plug part 2 along the preferred longitudinal axis of the plug part 2, which is designed to establish a mechanical and electrical contact with the mating connector 3. At the other, opposite axial end of the plug part 2 along the preferred longitudinal axis, connections 7 are formed for connecting wires of a cable to the socket contacts 15 of the plug part 2. This side is the connection-side end of the plug part 2. On the plug-side end of the plug part 2, a plug part adapter 5 is arranged or can be arranged on the plug part housing 4, since the plug part adapter 5 and the plug part 2 or the plug part housing 4 are shown in Figure 1 are (still) separated from each other. The plug adapter 5 has a sleeve or ring shape.

[0025] The mating connector 3 consists of one end of a cable 8 with (internal, and therefore in the Figure 1 non-visible) plug contacts 14, wherein a locking sleeve 9 is arranged circumferentially around the sheath of the cable 8. The locking sleeve 9 has a ring of identically designed and circumferentially equidistantly arranged locking means 10. The locking means 10 are formed by arms 11 which, proceeding from an inner sleeve part of the locking sleeve 9, protrude primarily parallel to the preferred longitudinal axis, are particularly flexible (bendable) in the radial direction, and have radially outward-projecting locking lugs 12 at the respective free end.

[0026] In Figure 2 is the first embodiment of a connector system 1 according to the invention according to Figure 1shown in a longitudinal sectional view, wherein plug part 2 and mating plug 3 are in mechanical and electrical contact with one another, i.e. are connected to one another. The plug part adapter 5 is arranged and fixed on the plug side on the plug part housing 4, wherein the plug part adapter 5 extends a short distance outside over the plug part housing 4 and, in this area, due to the ring or sleeve shape of the plug part adapter 5, also extends completely around the plug part housing 4. Only the part of the plug part adapter 5 with the circumferential plug-side taper protrudes - also on the plug side - along the preferred longitudinal axis against the plug-in direction over the plug part housing 4.At the inner transition between an inner circumferential wall of the plug part housing 4 and an inner circumferential wall of the plug part adapter 5, a latch 13 is formed in the form of a groove (recess, depression) that runs completely around the inside in a somewhat virtual (imaginary) common inner wall of the plug part housing 4 and the plug part adapter 5. The latch 13 is divided between the plug part housing 4 and the plug part adapter 5 in such a way that one of the two opposite flanks 21, 22 that delimit the latch 13 along the preferred longitudinal axis is part of the plug part adapter 5 and part of the plug part housing 4. The primary flank 21 is part of the plug part adapter 5 and the secondary flank 22 is part of the plug part housing 4. Particular attention is drawn to the detailed detail representations in . Figure 7 with the locking means 10 of the mating connector 3 in engagement in the locking latch 13 and in Figure 9without the locking means 10 of the mating connector 3. The Figure 9 refers to a longitudinal section in Figure 8 of the plug part 2 taken on its own without the mating plug 3. The transition 24 between the plug part housing 4 and the plug part adapter 5 takes place in the area of ​​the deepest point 23 of the latch 13 between the two flanks 21, 22. The deepest point 23 is extended somewhat in the axial direction parallel to the preferred longitudinal axis of the sleeve-shaped plug part housing 2 and thus the primary flank 21 and the secondary flank 22 are arranged at a distance from one another in the axial direction.

[0027] In the presentation of Figure 2 the locking lugs 12 of the locking means 10 of the mating connector 3 are fully engaged with the locking latch 13 of the plug part 2, i.e. locked in the locking latch 13. The section view in Figure 2The visible plug contact 14 of the mating connector 3 is in engagement with the corresponding socket contact 15 of the plug part 2. The mating connector 3 is connected both mechanically and electrically to the plug part 2. An internal thread 16 is formed on an inner wall of the plug part housing 4 along the preferred longitudinal axis, i.e., further away from the plug-side end of the plug part housing 4 or the plug part 2 than the latch 13. The internal thread 16 optionally enables the creation of a screw connection with a mating connector (not explicitly shown in any figure) that has a corresponding external thread. Such a mating connector does not have any latching means for engaging the latch 13 of the plug part to form a quick-disconnect connection, at least similar to the representation of the connector system 1 in the connected state according to the Figures 2 to 6A circumferential seal 17 is arranged inside the connector housing part 4, slightly deeper than the internal thread 16. This design allows the conversion of the plug connection with screwed connector parts to a plug connection with a quick-disconnect connection.

[0028] In the Figures 3 and 4 Two different designs of a (releasable) fastening of the plug adapter 5 to the plug housing 5 of a connector system 1 according to the invention are shown. In the design according to Figure 3 The plug adapter 4 is plugged onto the plug housing 3 and locked into place. For this purpose, the plug housing 3 has an outer circumferential groove (recess, depression) 18 and the plug adapter 5 has corresponding locking hooks or snap hooks 19, which are formed as moldings on an inner circumferential wall of the plug adapter and can be brought into engagement with the groove 18 or, as shown in Figure 3are in engagement with the groove 18. In the version according to Figure 3 The plug adapter 4 is connected to the plug housing 3 by means of a screw connection 20. For this purpose, the plug housing 4 has an external thread and the plug adapter 5 has a corresponding internal thread. Figure 4 The plug adapter 5 shown is more solid - with a significantly thicker jacket - than the one shown in the Figures 2 and 3 shown counterparts. From Figure 2 There are no obvious details regarding the fastening of the plug adapter 5 to the plug housing 4. However, a fastening of the plug adapter 4 to the plug housing by means of gluing or crimping (plastic deformation) that cannot be easily removed without causing damage would be in accordance with the Figure 2 shown representation of a connector system 1 according to the invention.

[0029] In Figure 5An embodiment of a connector system 1 according to the invention is shown with a plug adapter 5, which completely encompasses the locking latch 13 and additionally also the internal thread 16 for optionally forming a screw connection with a corresponding mating connector (not shown). The locking latch 13 is in this case completely formed on the plug adapter 5, which accordingly encompasses both flanks 21, 22 as well as the deepest point 23 of the locking latch 13 (not shown in detail). In this embodiment according to the invention, the plug adapter 5 is considerably larger and the plug housing 4 is correspondingly considerably smaller than in the Figures 1 to 4 shown embodiments of a connector system 1 according to the invention.

[0030] When designing a connector system according to the invention as shown in Figure 6The plug part adapter 5 is designed such that it can also be part of a device housing (not shown in detail), for example a wall of a device housing. The plug part adapter 5 is designed like a plate with at least one feedthrough for a mating connector 3 to form a quick-disconnect connection (and optionally a screw connection) with the plug part 2 of the connector system 1. The plate / plug part adapter 5 can be inserted into such a device housing, for example as part of a wall of a device housing, wherein the remainder of the plug part 2 can be connected to the plate / plug part adapter 5 either beforehand or afterwards. If the plate / plug part adapter 5 and the remainder of the plug part 2 are as shown in Figure 6connected to each other, then the plug-side end of the plug housing 4 borders one side of the plate 5 and defines the opening in the plate for the mating connector. This side of the plate would typically be part of the interior of a device housing. The latch 13 is similar to the one shown in the Figures 1 to 3In the exemplary embodiments shown of a connector system 1 according to the invention, the locking latch 13 is designed as an internally circumferential groove (recess, depression) in a somewhat virtual (imaginary) common inner wall of the connector part housing 4 and the passage in the plate 5 for the mating connector 3. The transition from the connector housing part 4 to the plate 5 is located at the lowest point 23 (not shown in detail) of the locking latch 13, so that the locking latch 13 is in turn divided between the connector housing 4 and the plate 5, with the primary flank 21 being arranged on the plate 5 and the secondary flank 22 on the connector part housing 4 (also not shown in detail).
