Description

Technical Field

[0001] The present invention relates to a plug connector system for forming a quick disconnect connection between a plug component and a corresponding mating plug having at least two latching lugs, wherein the plug component includes at least one plug component housing, particularly sleeve-shaped, having a preferred longitudinal axis, and the plug component has at least one latching slot for mating plugs around a first end side, which is the plug-side end side, which is at least effective along the preferred longitudinal axis in the axial direction, wherein the at least one latching slot is limited in a longitudinal range parallel to the preferred longitudinal axis by at least one primary sidewall and at least one secondary sidewall, wherein the primary sidewall and the secondary sidewall are arranged opposite to each other, and the primary sidewall defines the latching slot against the insertion direction, and the secondary sidewall defines the latching slot in the insertion direction. Background Technology

[0002] This invention belongs to the field of plug connector technology, particularly the field of circular plug connectors, including, for example, known embodiments of plug connectors with M12, M8, M23, or 7 / 8” threads. Such (circular) plug connectors and corresponding mating plugs are used to achieve current and / or signal transmission when the plug connectors and their respective mating plugs are respectively connected to each other. For this purpose, the plug connectors and mating plugs can be respectively arranged on the connection side at the ends of, for example, two current-carrying and / or signal-carrying cables, which are interconnected, or already interconnected, on the plug side via the plug connectors and mating plugs in a current-carrying and / or signal-carrying manner. However, alternatively, particularly the plug connectors, they can also be connected to a substrate or printed circuit board on the connection side. Or a similar structural connection. A mating connector may have one or more receptacle contacts as inward (“female”) contact openings and one or more outward (“male”) contact pins, while the mating contacts of the corresponding mating plugs have correspondingly mating contact pins or receptacle contacts. Typically, circular mating connectors and their respective mating plugs are threaded together, achieving a stable and load-bearing connection capable of withstanding mechanical loads, for example, from the connected machine, i.e., the mating connector is disposed, for example, on / inside the machine housing or equipment enclosure. However, establishing the threaded connection between the mating connector and the mating mating connector is complex, and the mating connector and the mating mating connector must have correspondingly mating threads.

[0003] In establishing a connection, a less complex alternative to the threaded connection of the plug connector and mating plug is a quick-disconnect connection, often better known by its borrowed English name, "push-pull." In this case, the mating plug has, for example, a latching device, which takes the form of a latching lug or latching hook extending radially, particularly in the insertion direction, on a resilient cantilever, latching arm, or similar structure extending axially in that direction. This latching device can engage and lock with one or more latching slots, latching recesses, or similar structures formed on the plug connector. When defining the insertion direction, it is not limited to the general assumption that the plug connector is stationary, and the corresponding mating plug moves linearly with its plug-side end face facing forward toward the plug-side end face of the plug connector until the latching device of the mating plug fully engages and latches in one or more latching slots on the plug component, thus forming a plug connection between the plug connector and the mating plug. The latching notch or latching recess here is, for example, formed as a radially recessed portion of the connector housing component of a plug connector in the insertion direction, and has sidewalls spaced apart from each other in the axial direction parallel to the insertion direction, which axially restrict the latching notch or latching recess. In particular, a first sidewall closer to the plug end of the plug connector is formed as a stop for a latching lug or latching hook. Another second sidewall, further away from the plug end of the plug connector and spaced opposite each other, can be formed as a stop for a latching lug or latching hook in the insertion direction, but this is not absolutely necessary. Other stops may also be provided that are effective in the insertion direction, do not directly and particularly affect the latching lug or latching hook, and generally relate to the stops of the latching device, which restrict the relative movement of the mating plug and the plug connector in the insertion direction. In this scenario, when forming the connection between the plug connector and the mating plug, the relative movement of the mating plug and the plug in the insertion direction should only be restricted in the insertion direction when the latch lug or latch hook (fully) engages with the respective corresponding latch slot or latch hook, preventing or having prevented the relative movement of the plug connector and the mating plug in the opposite direction of insertion. The separation of the connection between the plug connector and the mating plug, or the relative movement of the plug connector and the mating plug in the opposite direction of insertion, can only be resumed without destructive external intervention when the latch lug or latch hook disengages from the corresponding latch slot or latch recess by a corresponding radial offset. It is assumed here that the latch slot or latch recess is formed on the plug connector, and the latching device for engaging into the latch recess is formed on the corresponding mating plug. In principle, the opposite correspondence is also possible.

[0004] Such plug connectors are known from the prior art, which include both threads for forming a threaded connection with a corresponding mating plug and a latching notch or latching recess for forming a quick-disconnect connection with the corresponding mating plug. The corresponding mating plug then has a corresponding thread for forming a threaded connection with the plug connector, or a corresponding latching device for forming a quick-disconnect connection with the plug connector. The latching notch or latching recess is arranged on the inner wall around the plug-side end of the plug connector, typically formed, especially in a sleeve-like shape, on the plug-side end of the plug connector. The internal thread for forming the threaded connection is arranged at a greater distance from the plug-side end than the arrangement of the latching notch or latching recess on the inner wall of the plug connector housing, and thus extends somewhat deeper into the interior of the plug connector housing in the insertion direction.

[0005] While combining two different devices to form a detachable connection with the mating plug is advantageous in (circular) plug connectors, this design also has significant drawbacks. To allow the mating plug's correspondingly formed (external) thread for establishing a threaded connection with the plug connector to smoothly enter the plug housing component and establish a threaded connection on the plug-side end, a latching slot or latching lug is arranged on the inner wall of the plug housing in the insertion direction before the internal thread. Therefore, all portions of the inner wall of the plug housing between the internal thread and the plug-side end of the plug connector must have a larger radius than the portion of the plug housing component located in the internal thread region. Considering the certain depth of the latching slot or latching recess formed in the inner wall of the plug housing component in the form of a recess, and the fact that the plug housing component should also be stable under load in this area, it is clearly unavoidable that the outer circumference or outer diameter of the plug housing component in the latching recess region must also be larger than that in the external thread region. This could lead to the problem that such a plug connector is too large, especially in diameter, for recesses, channels, etc., in equipment housings, machine housings, or similar structures where such a plug connector is used for external contact and must be guided through the recess, channel, or similar structure at least by the end region on the plug side, where such recesses, channels, or similar structures are only suitable for the smaller diameters of known and / or standardized plug connectors, which are typically only formed to create a threaded connection with a mating plug. Summary of the Invention

[0006] Based on the shortcomings of the prior art, the purpose of this invention is to provide a plug connector system that is simple to manufacture, low in cost, can be used within the existing limitations of standardized circular plug connectors, and can easily replace known standardized circular plug connectors.

[0007] According to the invention, this objective is achieved by the plug connector system according to claim 1. Further advantageous designs are given in the dependent claims.

[0008] Therefore, at least one latching slot of the plug connector system according to the invention is formed at the transition from the plug component housing to the plug component adapter disposed on the plug side of the plug component housing, such that a primary sidewall is disposed on the plug component adapter and a secondary sidewall is disposed on the plug component housing, or both the primary and secondary sidewalls are disposed on the plug component adapter, wherein the primary sidewall is formed as a stop for the latching lug of the mating plug, which is effective against the insertion direction.

[0009] At least one latching wall, preferably formed as a recess, indentation, or similar structure in the plug-side end region of the plug component primarily in the radial direction, is provided, in part, defined by the latching wall along a preferred longitudinal axis. The sidewalls are not necessarily arranged in a plane perpendicular to the preferred longitudinal axis; they may form at least one acute angle with such a plane. In this sense, the sidewalls may be beveled. The sidewalls may also be formed as three-dimensional freeform surfaces and / or segmented by at least two partial sidewalls, wherein the partial sidewalls may further form at least one acute angle relative to each other. The provision of a primary sidewall with a latching wall on the plug component adapter and a secondary sidewall on the plug component housing means that the latching wall is divided between these two components of the plug component in the plug connector system according to the invention at the lowest point of the latching wall formed as a recess, indentation, or similar structure. The primary and secondary sidewalls may be directly adjacent to each other at the lowest point of the recess, indentation, or similar structure. However, the lowest point can also be an extended area, such that the primary and secondary sidewalls are axially spaced apart, particularly along the preferred longitudinal axis of the plug component housing. The lowest point extends axially parallel to the preferred longitudinal axis. If not, then it is not the lowest point of the latching jaw formed as a recess, indentation, or similar structure, but rather part of the primary or secondary sidewall.

[0010] Dividing the plug component into two adjacent housing portions along a preferred longitudinal axis has the advantage that the plug component housing, particularly in terms of its outer diameter, can be designed according to known standardized (circular) mating connectors. The necessary enlargement of the plug component's diameter due to the latching bayonet for quick disconnection with the corresponding mating plug can be limited on the plug component adapter. To stabilize the mating connector within the area of ​​at least one latching bayonet, the plug component adapter preferably extends externally in the longitudinal direction and also in the insertion direction above and at least partially around the plug-side end of the plug component housing component, and is particularly preferably secured or fixable to the plug component housing in a non-destructive or destructive release manner, at least in this overlapping area of ​​the plug component adapter and the plug component housing. In this way, the mating connector can be first guided by its plug component housing, for example, through a notch in a device housing or similar structure, through which the plug component housing can pass in diameter, but for which the plug component adapter is too large, and then the plug component adapter can be arranged on and secured to the plug component housing in a non-destructive or destructive manner.

[0011] For the production of this plug component of the plug connector system according to the invention, an undercut is not required in the proposed solution of forming at least one latching jaw at the transition from the plug connector housing component to the plug component adapter. In tool-down components, such an undercut requires considerable effort to demold when manufactured using conventional injection casting processes (plastic, zinc die casting, etc.), or in the worst case, cannot be demolded at all. This makes it much simpler and more cost-effective to produce such plug components in injection (pressure) casting processes using conventional workpiece demolding methods, especially without slides, or with special demolding methods (foldable cores, slides). Furthermore, the plug component housing and plug component adapter can be manufactured using different materials or combinations of materials, thus necessitating a better design of the plug connector according to the plug connector system of the invention, based on its intended use and the requirements thereof.

[0012] If at least one latching slot is entirely formed on the plug component adapter, i.e., the primary and secondary sidewalls of the latching slot, which are formed as a recess, indentation, or similar structure, are arranged on the plug component, then the advantages in terms of manufacturing technology may be lost. However, the plug component of the plug component of the plug connector system according to the invention can be formed, particularly in terms of outer diameter, according to known and / or standardized (circular) plug connectors, and the advantage remains unchanged because the increase in diameter caused by providing at least one latching slot for generating a quick disconnection connection with the corresponding mating plug can be completely transferred to the plug component adapter.

[0013] The plug component adapter can also be formed as part of a device housing, machine housing, or similar structure, in which the plug component of the plug connector system according to the invention can be mounted or has been mounted. In a simple variation, the plug component adapter can be, for example, a plate, in which the plug component or the plug component housing and the plate can be detachably fixed together or have been fixed together in a non-destructive or destructive manner. In this case, the plate is preferably formed and arranged perpendicular to a preferred longitudinal axis at least around the plug side end of the plug component housing. The plate has a channel for the corresponding mating plug in the position where the plate and the plug component housing are arranged adjacent to each other with their plug side ends, or where such arrangement is possible. The channel has the plug side end of the plug connector housing as its edge in the adjacent arrangement and / or fixed state of the plug component housing and the plate. At least one latching slot is formed in the form of a recess, indentation or similar structure in the common virtual (imaginary) inner wall of the plug component housing and the channel, such that the latching slot extends along a preferred longitudinal axis through the transition between the plug connector housing component and the plate, and wherein the primary sidewall of the latching slot is arranged on the plate, the secondary sidewall is arranged on the plug component housing, and the transition between the plug connector housing component and the plate is located exactly in the lowest point region of the latching slot.

[0014] According to a preferred design of the plug connector system conforming to the present invention, the plug component housing and the plug component adapter can be or are already connected to each other in a non-destructive, detachable manner, for example, by threaded connection, plug connection, or clamping connection.

[0015] In a preferred embodiment of the plug connector system according to the invention, the plug component housing and the plug component adapter may be or have been connected to each other in a destructively detachable manner, for example by adhesive bonding, welding, or plastic deformation (“crimping”).

[0016] A preferred design of the plug connector system according to the invention includes forming at least one latching notch on the inner wall of the plug connector housing component around the plug side end of the plug component.

[0017] According to a particularly preferred design of the plug connector system conforming to the present invention, the plug component housing and / or plug component adapter are formed of plastic material.

[0018] In a particularly preferred design variant of the plug connector system according to the invention, at least the plug component adapter is made of metal and / or metal alloy. Various manufacturing methods can be used here, such as casting methods, like injection casting, injection pressure casting, pouring and casting, and / or cutting methods (milling, turning).

[0019] A particularly preferred design variant of the plug connector system according to the invention includes forming at least one internal thread on the inner wall of the plug component housing, wherein the internal thread is arranged on the plug side at a position more inward along a preferred longitudinal axis than at least one latching jaw, and is formed to correspond to the external thread of the corresponding mating plug.

[0020] According to another particularly preferred design variant of the plug connector system conforming to the invention, at least one internal thread is arranged on the inner wall of the plug component adapter, at a location on the plug side further inward along a preferred longitudinal axis than at least one latching jaw, and is designed to correspond to the external thread of the corresponding mating plug. Since the internal thread is also part of the plug component adapter in this embodiment, the remaining portion of the correspondingly formed plug component, especially the plug component housing, can be formed more compactly, particularly in terms of its outer diameter.

[0021] What all three embodiments have in common is that the latching jaw is not formed by the plug component housing, but by the plug component adapter, and the required latching connection is established, in part, solely through the interaction of these components. Therefore, the aforementioned advantages are always achieved in terms of component manufacturing and load-bearing capacity.

[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 drawings and / or the features and combinations of features shown separately in the drawings, can be used not only in the combinations given respectively, but also in other combinations or individually.

Detailed Implementation

[0033] Figures 1 to 6 Different design variations of the mating connector system 1 according to the invention are shown. These designs differ only in specific details, rather than being fundamentally different from each other. Figure 1 A three-dimensional isometric view of a first design variant of the plug connector system 1 according to the invention is shown, wherein the basic elements of the plug connector system 1 are shown spaced apart from each other along a preferred longitudinal axis. The plug connector system 1 consists of a plug component 2 and a corresponding mating plug 3. Both the plug component 2 and the mating plug 3 are formed substantially rotationally symmetrically about the preferred longitudinal axis. The plug component 2 has, in particular, a sleeve-shaped plug component housing 4, in which a substantially cylindrical contact carrier 6 is arranged concentrically with the plug component housing 3 inside, carrying a socket contact 15 (in... Figure 1 (Not visible in the middle). Figure 1In this configuration, only the plug-side end of the contact carrier 6 is visible. The plug-side end of the plug component 2 is the end that forms for establishing mechanical and electrical contact with the mating plug 3, or more precisely, the axial end of the plug component 2 along its preferred longitudinal axis. A connecting portion 7 is formed on the other, opposite axial end of the plug component 2 along its preferred longitudinal axis, which is used to connect the core wire of the cable to the socket contact 15 of the plug component 2. This side is the connecting side end of the plug component 2. Because in Figure 1 In the illustration, the plug adapter 5 and the plug component 2 or the plug component housing 4 (still) are separate from each other, so the plug adapter 5 is arranged on or can be arranged on the plug side of the plug component 2 on the plug component housing 4. The plug adapter 5 here has a sleeve or annular shape.

[0034] The mating plug 3 is attached to the cable 8 (inside, therefore in) Figure 1 The end of the (invisible) insertion contact point 14 is formed, wherein a latching device sleeve 9 is arranged around the sheath of the cable 8. The latching device sleeve 9 has a ring of latching devices 10 that are formed identically and arranged equidistantly around the cable. The latching devices 10 are formed by arms 11 that start from the inner sleeve component of the latching device sleeve 9, project mainly parallel to the preferred longitudinal axis, and are particularly flexible (bendable) in the radial direction, and have radially outwardly projecting latching lugs 12 at their respective free ends.

[0035] Figure 2 It shows according to Figure 1The longitudinal sectional view shown is of a first embodiment of the plug connector system 1 according to the invention, wherein the plug component 2 and the mating plug 3 are in mechanical and electrical contact with each other, i.e., they are interconnected. A plug component adapter 5 is arranged and fixed to the plug side of the plug component housing 4, wherein the plug component adapter 5 extends outwardly onto a portion of the plug component housing 4, and in this region, due to the annular or sleeve shape of the plug component adapter 5, also extends completely around the plug component housing 4. Only the portion of the plug component adapter 5 with the surrounding plug-side narrowing—also on the plug side—extends beyond the plug component housing 4 along the preferred longitudinal axis against the insertion direction. At the internal transition between the surrounding inner wall of the plug component housing 4 and the surrounding inner wall of the plug component adapter 5, a latching notch 13 in the form of a groove (recess, recess) that completely surrounds the inner side is formed on a partially virtual (imaginary) common inner wall of the plug component housing 4 and the plug component adapter 5. The latching notch 13 divides the plug component housing 4 and the plug component adapter 5 such that one of the two opposing sidewalls 21, 22 that limit the latching notch 13 along a preferred longitudinal axis is part of the plug component adapter 5 and the other is part of the plug component housing 4. The primary sidewall 21 is part of the plug component adapter 5, and the secondary sidewall 22 is part of the plug component housing 4. Particular reference is made in this regard. Figure 7 and Figure 9 Detailed partial images in the middle, Figure 7 The latching device 10 of the mating plug 3 engages with the latching bayonet 13, and Figure 9 The latching device 10 does not have a matching plug 3. Figure 9 This involves Figure 8 The plug component 2 does not have a separate longitudinal sectional view of the mating plug 3. The transition 24 between the plug component housing 4 and the plug component adapter 5 occurs in the region of the lowest point 23 of the latching jaw 13 between the two side walls 21, 22. The lowest point 23 extends axially parallel to the preferred longitudinal axis of the sleeve-shaped plug component housing 2, so that the primary side wall 21 and the secondary side wall 22 are axially spaced.

[0036] exist Figure 2 In the diagram, the latch lug 12 of the latching device 10 of the mating plug 3 is fully engaged with the latch slot 13 of the plug component 2, i.e., locked in the latch slot 13. The mating plug 3 in... Figure 2The cross-sectional view shows that the insertion contact 14 engages with the corresponding socket contact 15 of the plug component 2. The mating plug 3 and plug component 2 are mechanically and electrically connected. An internal thread 16 is formed on the inner wall of the plug component housing 4, deeper than the latch 13 arranged along the preferred longitudinal axis, i.e., further away from the plug-side end of the plug component housing 4 or the plug component 2. This internal thread 16 selectively enables a threaded connection with a mating plug (not explicitly shown in any figure) having a corresponding external thread. This mating plug does not have any latching device for engaging with the latch 13 of the plug component to form a quick-disconnect connection, at least not with... Figures 2 to 6 The illustrated plug connector system 1 has a similar latching device in the connected state. A surrounding seal 17 is arranged inside the plug connector housing component 4, extending further than the internal thread 16. This design makes it possible to convert a threaded plug connection with a plug component into a plug connection with quick-disconnect capability.

[0037] Figure 3 and Figure 4 Two different embodiments are shown where the plug component adapter 5 is (removably) fixed to the plug component housing 5 of the plug connector system 1 according to the invention. Figure 3 In one embodiment, the plug adapter 4 is inserted into and locked onto the plug housing 3. For this purpose, the plug housing 3 has an externally surrounding groove (recess, recess) 18, and the plug adapter 5 correspondingly has a latch hook or snap hook 19, which is formed as a molded portion on the surrounding inner wall of the plug adapter and can engage with the groove 18 or... Figure 3 The shown engages with groove 18. According to... Figure 3 In one embodiment, the plug component adapter 4 is connected to the plug component housing 3 via a threaded connection 20. For this purpose, the plug component housing 4 has external threads, and the plug component adapter 5 has corresponding internal threads. Figure 4 The plug component adapter 5 shown is... Figure 2 and Figure 3 The similar product shown is more robust—the outer layer is much thicker. Figure 2 No obvious details are shown regarding the attachment of the plug adapter 5 to the plug housing 4. However, attaching the plug adapter 4 to the plug housing in a manner that prevents easy removal without damage by gluing or pressing (plastic deformation) also conforms to the plug connector system 1 according to the invention. Figure 2 The situation is shown in the figure.

[0038] Figure 5An embodiment of the plug connector system 1 according to the invention is shown, wherein there is a plug component adapter 5 that fully comprises a latching jaw 13, and additionally has internal threads 16 for selectively forming a threaded connection with a corresponding mating plug (not shown). In this case, the latching jaw 13 is fully formed on the plug component adapter 5, and therefore includes two sidewalls 21, 22 and a lowest point 23 of the latching jaw 13 (not shown in detail). In this embodiment according to the invention, with Figures 1 to 4 Compared to the embodiment of the plug connector system 1 according to the present invention, the plug component adapter 5 is much larger and the plug component housing 4 is correspondingly much smaller.

[0039] In such Figure 6 In the embodiment of the plug connector system according to the invention shown, the plug component adapter 5 is designed to simultaneously be part of a device housing (not further shown), such as a wall of the device housing. The plug component adapter 5 is here designed as a plate having at least one channel for mating plug 3, for forming a quick-disconnect connection (and selective threaded connection) with the plug component 2 of the plug connector system 1. The plate / plug component adapter 5 can be joined to such a device housing, for example, as part of a wall of the device housing, wherein the remainder of the plug component 2 can be connected to the plate / plug component adapter 5 beforehand or afterwards. If the plate / plug component adapter 5 and the remainder of the plug component 2 are as follows... Figure 6 As shown, when connected together, the plug-side end of the plug component housing 4 adjoins one side of the plate 5 and serves as the edge of the channel in the plate for mating the plug. This side of the plate is typically part of the inner side of the device housing. Figures 1 to 3 Similar to the embodiment of the plug connector system 1 according to the invention shown, the latching slot 13 is formed as an interior surrounding groove (recess, recess) in a partially virtual (imaginary) common inner wall of the channels for mating plugs 3 in the plug housing 4 and plate 5. The transition from the plug connector housing 4 to the plate 5 is located at the lowest point 23 (not shown in detail) of the latching slot 13, thus the latching slot 13 again divides between the plug connector housing 4 and the plate 5, wherein a primary sidewall 21 is arranged on the plate 5 and a secondary sidewall 22 is arranged on the plug housing 4 (again not shown in detail).
