[0001] This application claims priority from European patent application No. 24 165 189.2, the content of which is incorporated herein in its entirety by reference. TECHNICAL FIELD

[0002] The present invention relates to a termination assembly of a cable connector arrangement, comprising a termination cap which is mountable on a cable-side end portion of a connector housing of the cable connector arrangement, and a cable strain relief which is fastenable to a cable of the cable connector arrangement.

[0003] The present invention further relates to a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology, having a termination assembly.

[0004] The present invention further relates to a method for assembling a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology. BACKGROUND

[0005] In various embodiments, cable connectors are known as essential components in many electronic devices and systems. These cable connectors are intended to achieve a reliable electrical connection between the components involved and serve for the transmission of electrical power and / or data signals to a corresponding mating connector. Typical applications include the connection of electronic assemblies in computers, communication devices, automobiles and many other fields.

[0006] In the case of mounting a cable connector on a cable, a key challenge is to mount the various components of the cable connector on the cable, as shown for example in DE 10 2014 200 133 A1 Figure 1 and Figure 2 .

[0007] The connector components which generally have to be mounted in the region of the cable inlet (also referred to as "cable outlet" or "cable passage") are referred to as "termination cap", which is generally the last connector component to be fastened to the cable-side end portion of the connector housing. Furthermore, a cable strain relief is generally mounted in the cable-side end portion section of the cable connector, which serves to prevent the cable from being pulled out or released from the cable connector in an uncontrolled manner. Finally, a cable and / or housing seal is sometimes mounted in the region of the cable outlet. This list is not to be understood as exhaustive.

[0008] Therefore, assembling cable connectors can be very complex and typically must be done carefully and time-consuming by highly trained professionals or sophisticated assembly equipment. Consequently, the assembly of individual connector components is a significant factor affecting the economic efficiency of mass production of cable connectors, and it is necessary to improve the efficiency of this process to save time and costs during connector assembly.

[0009] For further technical background, please refer to the following documents: EP 2 816 672 A1 relates to a cable stress relief system having a guide receptacle and at least one actuating jaw assigned to the guide receptacle. The actuating jaw is capable of moving substantially along the longitudinal axis of the inserted cable from a pre-latch position to a final blocking position. US 2019 / 0044277 A1 relates to a similar cable connector arrangement having a cable stress relief device. The cable stress relief device includes a pair of cable clamps with opposing inclined surfaces attached to an inner surface. CN 112448220 A relates to an end cap for an electrical connector having a cable stress relief device that can be screwed in during assembly. Finally, CN 117317687 A also relates to a cable fastening device with a cable clamp including a body and a plurality of resilient claws for clamping a cable, the body having a cable through-hole allowing the cable to pass through. Summary of the Invention

[0010] In view of the prior art, the object of the present invention is to provide a termination assembly for a cable connector arrangement and a cable connector arrangement, preferably which can be installed on a cable in a particularly simple and economical manner.

[0011] Another object of the present invention is to provide a method for assembling cable connector arrangements, by means of which the termination components of the cable connector arrangements can be preferably installed on the cable in a particularly simple and economical manner.

[0012] This objective is achieved by the features of claim 1 for the termination assembly. In terms of cable connector arrangement, this objective is achieved by the features of claim 14, and in terms of method, this objective is achieved by the features of claim 15.

[0013] The dependent claims and the features described below relate to advantageous embodiments and variations of the invention.

[0014] The present invention relates to a termination assembly for a cable connector arrangement, the termination assembly including a termination cap and a cable stress relief device, the termination cap being mountable on the cable-side end of the connector housing of the cable connector arrangement, and the cable stress relief device being fastened to the cable of the cable connector arrangement.

[0015] Preferably, the cable connector arrangement, connector housing, cable connector, and cable should not be construed as part of the termination assembly for which protection is claimed. However, the applicant reserves the right to claim protection individually or separately for the termination assembly, cable connector arrangement, connector housing, cable connector, and cable, or various combinations thereof, in each case.

[0016] Specifically, the cable can be any type of cable or optical fiber (e.g., the cable can have a single-core, multi-core, coaxial, twisted-pair, etc. design). The cable typically has a cable sheath that encloses internal cable components, such as one or more cable cores and / or cable shielding. Preferably, a cable stress relief device can be fastened to the cable sheath, preferably to the cable end section.

[0017] Specifically, the cable connector can be any type of cable connector or optical fiber connector. Preferably, the cable connector can be a high-voltage connector used for transmitting voltage and current in high-voltage technology. However, for example, the invention can also be used in conjunction with a data connector for transmitting data signals.

[0018] Termination assemblies or their individual components, connector housings and cable seals (also mentioned below), and any other components (such as support sleeves or one or more contact elements) may also be referred to below as “connector components” of a cable connector.

[0019] In the pre-assembled state of the termination assembly, i.e., before the termination cap is mechanically connected to the connector housing, the cable stress relief device is connected to the termination cap in a non-detachable manner.

[0020] Since the cable stress relief device is already securely connected to the termination cap in a pre-assembled state (that is, before the termination assembly is assembled, and therefore, for example, in the delivery state of the termination assembly), the termination cap and the cable stress relief device can be treated as common components during connector assembly. This reduces the assembly complexity (and thus also reduces assembly time) and the probability of errors during connector assembly.

[0021] The "anti-detachment connection" is preferably a form-fit connection between the cable stress relief device and the termination cap, particularly (but not exclusively) as described below. However, in principle, the "anti-detachment connection" can be any desired mechanical connection that ensures that the cable stress relief device and the termination cap do not accidentally separate before the termination cap is installed on the connector housing. For example, alternatively or additionally, the "anti-detachment connection" can therefore also be a material-bonded connection and / or a force-fit connection.

[0022] For example, a material bond connection can be provided by one or more welded or bonded points between the cable stress relief device and the termination cap, which are formed during the pre-assembly or manufacturing of the cable stress relief device and the termination cap. In particular, the material bond connection is formed in such a way that the material bond connection (i.e., welded or bonded points) can be broken again during assembly (e.g., at a predetermined break point).

[0023] Where appropriate, an integrated construction of the cable stress relief device and the termination cap may also be provided, to achieve a non-detachment connection in the pre-assembled state, for example by means of a movable connection between the cable stress relief device and the termination cap, particularly by using at least one thin-film hinge.

[0024] The cable stress relief device and the termination cap can also be initially immovably connected via one or more predetermined break points, so that the cable strain relief device and the termination cap can be produced and shipped together first, wherein the predetermined break points are then intentionally broken by the assembler or assembly equipment by installing the termination cap on the connector housing or even before that.

[0025] Similarly, a force-fit connection can be provided between the cable stress relief device and the termination cap to provide a non-detachment connection in the pre-assembled state. For this purpose, the cable stress relief device can be press-fitted into the termination cap during pre-assembly, with an optional enhanced frictional engagement between the two (e.g., due to the shell-side roughness on the cable stress relief device and / or the termination cap).

[0026] Within the scope of this invention, combinations of different connection technologies are also obviously possible.

[0027] However, as mentioned above, the present invention is described below primarily based on the anti-detachment connection of the cable stress relief device and the termination cap in a pre-assembled state with a pure form fit; however, this should not be construed as limiting.

[0028] During the installation of the termination cap onto the connector housing, the cable stress relief device can be moved by the connector housing along the cable-side end of the termination cap (i.e., particularly the end facing away from the connector housing).

[0029] Because the cable stress relief device can be "automatically" moved within the termination cap by the connector housing during assembly, thus being brought to its final end position within the termination cap, the assembly of these two connector components is further simplified. Therefore, the assembler or device used to assemble the cable connector arrangement only needs to install the termination cap, which simultaneously results in the installation of the cable stress relief device, without requiring a separate installation step for this purpose.

[0030] To enable the cable stress relief device to be moved by the connector housing during assembly, it may be specifically specified that the end face of the cable stress relief device facing the connector housing and / or the actuating surface formed on the inner shell and / or outer shell of the cable stress relief device can be accessed from the connector-side end of the termination cap. In this way, the connector housing (or at least a portion of the connector housing) can indirectly or directly contact the actuating surface, thereby causing movement of the cable stress relief device.

[0031] According to the present invention, when the cable stress relief device is connected to the termination cap in a non-detachable manner, the mobility of the cable stress relief device is restricted at least in the axial direction in the pre-assembled state.

[0032] The limited axial movement of the cable stress relief device means that, in some cases, movement in the axial direction (i.e., movement along or against the assembly direction) is indeed possible, but such movement is limited to a pre-assembled position and an end position, wherein the pre-assembled position is preferably arranged closer to the connector-side end of the end cap than the end position.

[0033] According to the present invention, the termination cap can be latched together with the connector housing at its connector-side end section.

[0034] For this purpose, the end cap has at least one latching device for latching with a corresponding mating latching device of the connector housing. Preferably, the end cap has at least two latching devices or even more latching devices spaced apart from each other circumferentially.

[0035] According to the invention, at least one latching device is designed to have a latching tab that is resilient in the lateral direction (i.e., laterally, preferably perpendicular to the axial direction), that is, for example, in the form of a latching arm or a latching rocker.

[0036] To provide elasticity to the latching device or latching tab, a longitudinal slot or groove can be formed in the sidewall of the end cap, which can be configured to be located circumferentially next to the corresponding latching device or latching tab.

[0037] According to the present invention, the cable stress relief device has at least one connecting device, and the end cap has at least one mating connecting device to restrict mobility (at least in the axial direction).

[0038] Therefore, the connecting device and the mating connecting device are preferably designed and arranged on the cable stress relief device and the termination cap such that the connecting device is mechanically blocked by the mating connecting device (i.e., abuts against the mating connecting device), or the mating connecting device is mechanically blocked by the connecting device (i.e., abuts against the connecting device). The axial movement restriction can be provided in particular by ensuring that, during the axial movement of the cable stress relief device and the termination cap relative to each other, the connecting device and the mating connecting device abut against each other at least at a defined stopping position.

[0039] According to the invention, the latching device or latching tab of the termination cap has the aforementioned mating connection device. In this way, the same component can advantageously provide the following dual functions in the termination cap: securing the cable stress relief device in the pre-assembled state and latching it together with the connector housing in the assembled state.

[0040] In an improved embodiment of the invention, the terminal cap may be configured to have at least two latching devices circumferentially spaced apart from each other, the at least two latching devices being used to latch together with corresponding mating latching devices of the connector housing.

[0041] The mechanical stability of the termination assembly can be increased by distributing multiple latching devices along the circumference of the termination cap. Due to the specific distribution or arrangement of the latching devices along the circumference of the termination cap, anti-rotation devices and / or mechanical coding can be provided to ensure that the cable stress relief device is installed in the termination cap only in a single direction or a specific predetermined direction.

[0042] In an improved embodiment of the invention, the latching tab may be configured as a latching hook or similar latching protrusion having a mating latching device for the connector housing (the mating latching device being designed as a latching recess), but preferably, the latching tab has a latching recess having a mating latching device for the connector housing (the mating latching device being designed as a latching protrusion) (therefore, the latching tab may be, for example, U-shaped).

[0043] Preferably, the connecting device has at least one blocking surface, and the mating connecting device has at least one mating blocking surface, the at least one blocking surface and the at least one mating blocking surface being able to abut against each other to restrict the mobility of the cable stress relief device in a pre-assembled state. The blocking surface and the mating blocking surface can, in principle, be of any desired shape, particularly primarily flat, but optionally, they can also be concave / convex or curved in some other way. As alternatives to or additions to the blocking surface and the mating blocking surface, (matting) blocking tips, (matting) blocking edges, or other structures that can serve as stops may also be provided, particularly combinations of the above variations. It should also be mentioned that, if suitable, multiple blocking surfaces can abut against a common mating blocking surface, or a common mating blocking surface can abut against multiple blocking surfaces.

[0044] Preferably, the area vector of the blocking surface and / or the area vector of the mating blocking surface extends at least substantially axially, or along the assembly direction of the cable stress relief device in the terminal cap, or against that assembly direction. However, the area vector may also extend, for example, in the radial direction, that is, preferably laterally or orthogonally to the axial / assembly direction. Preferably, the area vector of the blocking surface extends in the opposite direction to the area vector of the mating blocking surface. Blocking surfaces and / or mating blocking surfaces oriented obliquely relative to the longitudinal axis of the cable stress relief device or relative to the axial direction (that is, for example, conical blocking surfaces / matting blocking surfaces) are also possible in principle.

[0045] The blocking surface / fitting blocking surface may be formed on the side surface of the lateral extension also mentioned below and / or formed on the lug, pin, web, rib, flange segment or the like.

[0046] The blocking surface / fitting blocking surface can be the end face, side surface and / or inner surface of the recess.

[0047] The blocking surface / fitting blocking surface may extend completely around the perimeter in the circumferential direction, especially if the blocking surface / fitting blocking surface is formed on the flange-like section of the termination cap or cable stress relief device, or extend only along the inner or outer circumferential section, especially if the blocking surface / fitting blocking surface is formed on the lateral extension, lug or the like.

[0048] According to an improved embodiment of the invention, at least one connecting device of the cable stress relief device may be configured to engage with at least one mating connecting device of the termination cap in a pre-assembled state of the termination assembly, so as to restrict the mobility of the cable stress relief device at least in the axial direction or in the assembly direction or against the assembly direction.

[0049] Preferably, at least two connecting devices are provided, which are spaced apart from each other in the circumferential and / or axial directions. For example, three, four, five, six or even more connecting devices may be provided, distributed along the circumference and / or longitudinal range of the cable stress relief device, particularly spaced at equal intervals. When exactly two connecting devices are provided, these two connecting devices may preferably be offset relative to each other in the circumferential direction or opposite to each other or offset by 180° in the circumferential direction.

[0050] According to an improved embodiment of the invention, the connecting device of the cable stress relief device can be designed as a lateral extension, and the mating connecting device of the end cap can be designed as a receiving portion for the lateral extension. Then, a blocking surface can be formed, for example, laterally on the lateral extension, and a mating blocking surface is formed on the inner surface of the receiving portion, such that the blocking surface can abut against the area of ​​the inner surface of the lateral extension that serves as an end stop (that is, for example, at the opposite ends of the elongated recess, also mentioned below).

[0051] It should also be emphasized that the mating connection device (with mating blocking surface) of the termination cap can be designed as a lateral extension, and the connection device (with blocking surface) of the cable stress relief device can be designed as a receiving part for the lateral extension.

[0052] At least one receiving portion for at least one lateral extension is preferably a recess, particularly one or more holes (i.e., through holes or window-shaped openings) in the sidewall of the end cap. However, if suitable, the recess may also be a recess in the sidewall (i.e., a blind hole or groove). Alternatively, at least one receiving portion for at least one lateral extension may also be one or more steps, edges, webs, ribs, grooves, or other suitable mating connections to provide the desired restriction of movement.

[0053] The connecting device or mating connection device of the cable stress relief device can preferably be designed as a recess, especially an elongated hole, as will be explained below.

[0054] The recess is preferably an elongated recess (hereinafter referred to as "elongated hole"), particularly an elongated hole extending in the axial direction, and especially preferably an elongated hole extending linearly in the axial direction. Preferably, at least one elongated hole extends in the axial direction at least between the pre-assembly position and the end position, or at least the longitudinal extent of the elongated hole may correspond at least to the distance between the pre-assembly position and the end position.

[0055] In this regard, it should be mentioned that the mobility of the cable stress relief device can also be restricted at least in the lateral or radial direction and / or in the rotational or circumferential direction. Specifically, rotational movement restriction can also be achieved by at least one lateral extension that engages accordingly with the termination cap, such that rotation of the cable stress relief device and the termination cap relative to each other (i.e., movement in the circumferential direction) is possible only to a limited extent, or is completely locked. In particular, lateral or radial movement restriction can be achieved by arranging the cable stress relief device within the (preferably sleeve-shaped) termination cap, such that lateral mobility can be defined by the potential gap between the external dimensions of the cable stress relief device and the internal dimensions of the termination cap in the installed state (i.e., particularly by the difference between the outer diameter of the cable stress relief device and the inner diameter of the termination cap). Preferably, the cable stress relief device is at least approximately or completely received within the termination cap, with no gap relative to rotation or movement in the circumferential direction and / or movement relative to the lateral or radial direction.

[0056] In an improved embodiment of the present invention, the cable stress relief device and the termination cap can be configured to form a mutual guiding function, for guiding the cable stress relief device to move toward the cable-side end of the termination cap.

[0057] In particular, it can be specified that at least one latching tab has a guiding function for guiding the cable stress relief device toward the cable-side end of the terminal cap, and in particular has a recess for receiving the protrusion of the cable stress relief device, preferably for receiving a connecting device, and the recess is preferably an elongated hole.

[0058] In particular, if the latching tabs have elongated recesses, these recesses can guide the corresponding protrusions, such as the lateral extensions of a cable stress relief device, in a defined manner along their longitudinal extent. Therefore, during the assembly of the terminal cap along a defined path, the movement of the cable stress relief device in the cable-side direction of the terminal cap can be predetermined. This is preferably, but not necessarily, a linear guide in the axial direction. However, in principle, any desired guidance can be provided by the recesses, that is, for example, a curved path that, in addition to axial movement, describes rotation in the circumferential direction through defined angular segments.

[0059] Preferably, the mating connection of the latching tab (which restricts the mobility of the cable stress relief device in the pre-assembled state) can be configured to simultaneously form a guiding function, particularly a guiding function for the connecting device of the cable stress relief device. Therefore, preferably, the mating connection can be designed as an elongated recess or orifice in which the connecting device can move unrestricted from the pre-assembled state all the way to the cable-side end of the termination cap.

[0060] In this way, the (elongated) recess or elongated hole can advantageously achieve a dual function, providing a movement restriction device (and optionally a guide) for the cable stress relief device on the one hand, and a latching option for mounting on the connector housing on the other.

[0061] However, alternatively, for example, the latching tab's mating connection device can be formed separately from the guide, which restricts the mobility of the cable stress relief device in the pre-assembled state. Thus, the latching tab can, for example, have an elongated hole separated by a web, and this elongated hole forms a separate receiving portion in the front section for the connection device of the cable stress relief device, thereby restricting the mobility of the cable stress relief device in the pre-assembled state, and this elongated hole forms a guide in the rear section, so that the cable stress relief device, after being disengaged from the front section, is guided all the way to the cable-side end of the termination cap.

[0062] It should be emphasized that the guiding function of the cable stress relief device or its lateral extension through the recess is advantageous, but not absolutely necessary within the scope of the invention.

[0063] Furthermore, it should be mentioned that the design of the lateral extension portion to the cable stress relief device and the recessed portion to the termination cap can be interchanged, such that the termination cap has the at least one lateral extension portion, and the cable stress relief device has the at least one (elongated) recessed portion or elongated hole. Additionally, if the cable stress relief device is supported, for example, at at least two locations along the axial direction on the inner side surface of the termination cap (i.e., supported, for example, by at least two lateral extension portions arranged offset from each other along the axial direction), the recessed portion can be completely omitted. Alternatively, if the outer side surface of the cable stress relief device is guided directly along the inner side surface of the termination cap, the lateral extension portion and the recessed portion can also be optionally completely omitted.

[0064] In an improved embodiment of the invention, the cable stress relief device is locked in a pre-assembled position within the termination cap, particularly in the connector-side end section of the termination cap, during the pre-assembled state of the termination assembly.

[0065] The locking is preferably achieved by at least one locking device formed in the termination assembly.

[0066] Due to this locking mechanism, the mobility of the cable stress relief device within the termination cap in the pre-assembled state can not only be restricted but also clearly defined (particularly in the axial direction, but preferably also in the lateral or radial and / or circumferential directions). The corresponding locking position can further simplify assembly, as the cable stress relief device is thus in a known and fixed state at least at the start of assembly.

[0067] Preferably, the locking device may be a latch lug or some other protrusion on the inner side surface of the end cap to form a stop for the cable stress relief device, particularly a stop for the end face, such as a flange-shaped end face of the cable stress relief device (however, alternatively, the cable stress relief device may also include a protrusion, i.e., a latch lug, and the end cap may include a stop, such as a recess).

[0068] Preferably, at least two locking devices can be provided for the end cap, which are arranged spaced apart from each other in the circumferential direction, for example, arranged opposite each other in the circumferential direction. In principle, any number of corresponding locking devices can be provided, that is, for example, two, three, four, five, six or even more locking devices spaced apart from each other in the circumferential direction (e.g., equidistantly distributed in the circumferential direction) can also be provided.

[0069] In particular, the locking devices can also be formed in pairs, wherein, for example, the first pair of locking devices (e.g., latch lugs) are arranged laterally next to the recesses already mentioned above, such that the recesses (especially elongated holes) are located between the same pair of locking devices. Preferably, in this case, for example, each of the recesses can be laterally surrounded by a pair of locking devices, which may be advantageous for unlocking during the assembly of the termination assembly (also described below).

[0070] In an advantageous improvement of the invention, the cable stress relief device can be configured such that, during the installation of the termination assembly onto the connector housing, the locking mechanism is unlockable, allowing the cable stress relief device to move from its pre-assembled position toward the cable-side end of the termination cap.

[0071] This unlocking can be done manually (e.g. with the aid of tools), but is preferably done indirectly or directly through the connector housing.

[0072] Specifically, it can therefore be configured such that at least one segment of the connector housing is capable of unlocking the locking device during assembly (preferably the forward segment of the connector housing in the assembly direction, such as the "coupling latch" of the connector housing, which will also be mentioned below).

[0073] The termination cap section with the locking device may be elastically movable, particularly elastically deflectable / elastically movable in the lateral or radial direction, such that the termination cap can be at least temporarily opened during assembly to release the lock by lifting the locking device. Alternatively or additionally, at least one section of the cable stress relief device may be elastically movable at least in the region of the locking device, particularly elastically deflectable / elastically movable in the lateral or radial direction, such that the cable stress relief device is at least temporarily compressible or can be squeezed together during assembly to release the lock of the locking device.

[0074] Preferably, the locking of the cable stress relief device can be non-destructively unlocked during the installation of the termination cap onto the connector housing (e.g., through the resilient mobility of the termination cap section with the locking device described above). However, destructive, and therefore often permanent, unlocking can also be provided, for example, by breaking off a predetermined break point or similar portion (less preferred). For example, the locking device / latch lug can thus be broken off in a defined manner to unlock the cable stress relief device during assembly.

[0075] In an improved embodiment of the invention, the cable stress relief device can be configured to move all the way to the cable-side end section of the termination cap during the installation of the termination cap onto the connector housing, preferably all the way to the end position, particularly the end position of the cable-side end section of the termination cap.

[0076] Preferably, the cable stress relief device is fixed to the cable in the end section on the side of the cable (that is, at the end position, for example), particularly by means of force engagement.

[0077] It can be configured such that the cable stress relief device is fixed at the end position within the termination cap. This (optional) fixing can be achieved, for example, by a latch between the cable stress relief device and the termination cap at the end position. However, typically (but not absolutely necessary), the cable stress relief device can be fixed at the end position by the connector housing, which is achieved by clamping the cable stress relief device between the connector housing and a stop in the termination cap. Therefore, the cable stress relief device is preferably pressed at its end position against a stop (e.g., a step) formed on the cable-side end of the termination cap by the connector housing (preferably by a mating latch of the connector housing or another forward section of the connector housing in the assembly direction).

[0078] It can be configured such that the cable stress relief device has retaining tabs (optionally with fastening hooks disposed at the free end) arranged around the circumference. The retaining tabs can be designed to be elastic in the lateral or radial direction.

[0079] It can be configured such that the retaining tab, in its mechanically relaxed state, defines an inner circumference smaller than the outer circumference of the cable, such that pushing it onto the cable causes mechanical deformation of the retaining tab, resulting in the retaining tab being force-fitted onto the cable. However, as an additional or supplementary configuration, it can also be configured such that, during the movement of the cable stress relief device to the end position, the retaining tab is pressed against the cable with increased clamping force due to mechanical interaction with the termination cap. For this purpose, for example, it can be configured such that the retaining tab is pushed into an axial section of the termination cap, which tapers (e.g., linearly, curvilinearly, and / or stepwise) toward the cable-side end.

[0080] It should also be mentioned that the movement of the cable stress relief device during assembly does not necessarily have to proceed all the way to the end position, or at least not until it reaches some other fixed structure in the cable-side end section of the stop or termination cap. The movement of the cable stress relief device may, for example, be limited by sufficient force-fit fixation on the cable (sheath)—that is, the cable stress relief device is moved during assembly toward the cable-side end of the termination cap until the expected force-fit fixation of the cable stress relief device on the cable (sheath) is achieved, which is sufficient. Because of the remaining axial clearance in the direction toward the cable-side end of the termination cap, tolerances can be compensated for, and (if appropriate) even the termination assembly can be used for different cable diameters.

[0081] In an improved embodiment of the present invention, the following configuration may also be made: in the pre-assembled state, the termination assembly, in addition to having a cable stress relief device, also has other anti-detachment connectors or other components, particularly cable seals and / or housing seals that are anti-detachedly connected to the termination cap and / or the cable stress relief device.

[0082] The other components (i.e., cable seals and / or housing seals) may be connected to the cable stress relief device or to the end cap, for example, by means of material bonding (preferably), form fitting and / or force fitting.

[0083] Preferably, the elastomer can be overmolded onto the lateral end of the cable stress relief device (e.g., at the connector side end) to form a seal (e.g., a cable seal). In particular, this can provide a two-component injection molding method for attaching other components to the cable stress relief device and / or termination cap in a material-bonded manner.

[0084] Since other components are even securely attached to the termination cap, the assembly of the cable connector arrangement can be further simplified.

[0085] In an advantageous improvement of the invention, the termination cap and the cable stress relief device may be configured to be annular or sleeve-shaped, and each has a cable through-hole for the cable.

[0086] The sidewalls of the termination cap and / or cable stress relief device may have any desired grooves (e.g., longitudinal grooves) or other recesses / recesses and / or protrusions.

[0087] In principle (in less preferred embodiments), the termination cap and / or cable stress relief device can also be configured as a partially annular or continuously slotted sleeve. For example, a longitudinal slot can be provided that extends completely through the termination cap or cable stress relief device in the axial direction. However, it is preferable that the termination cap and / or cable stress relief device is completely annular or closed around its perimeter, at least in the axial section (e.g., in a flanged end section).

[0088] It should be noted that termination assemblies, cable stress relief devices, and / or termination caps need not necessarily be (hollow) cylindrical, but can in principle have any desired cross-sectional geometry. Therefore, rectangular or other cross-sectional geometries are also suitable, for example, and the invention is described below primarily based on a hollow cylindrical cross-sectional geometry—but this is merely for the sake of simplicity and not to limit the claimed subject matter to at least substantially circular cross-sectional geometries. Therefore, if the terms “radial” or “circular” are used below, for example, those skilled in the art can generalize or replace them with corresponding terms that also relate to or include other cross-sectional geometries in case of doubt.

[0089] Preferably, the cable stress relief device is at least partially housed within the termination cap.

[0090] The present invention also relates to a cable connector arrangement, particularly a cable connector arrangement for high voltage technology, the cable connector arrangement having a termination assembly, a connector housing and a cable according to the context embodiment, wherein a termination cap is mounted on the connector housing and a cable stress relief device is fastened to the cable.

[0091] The anti-detachment fastening of the cable stress relief device to the termination cap in the pre-assembled state, and the subsequent "automatic" movement of the cable stress relief device in the termination cap toward the cable end during assembly, optimize the assembly process overall, which may be particularly advantageous in the context of mass production.

[0092] Cable connector arrangements or termination assemblies are particularly advantageous for use with high-voltage connectors, regardless of the type and purpose of the connector. Therefore, cable connector arrangements or termination assemblies can also be suitable for high-frequency technologies, i.e., for example, for data connectors.

[0093] The present invention also relates to a method for assembling cable connector arrangements, particularly for cable connector arrangements for high-voltage technology, the method comprising at least the following steps: -Provide cable and connector housings; - Provides a termination assembly having a termination cap and a cable stress relief device that is grounded to the termination cap to prevent detachment; - The termination cap is mounted on the connector housing, while the cable stress relief device moves from the connector housing toward the cable-side end of the termination cap, and is preferably fastened to the cable; and - The termination cap is latched onto the connector-side end section of the connector housing by means of at least one latching device of the termination cap designed as a latching tab and a corresponding mating latching device of the connector housing.

[0094] It can be configured such that: the latching tab has a mating connection for the connection device of the cable stress relief device, so as to restrict the mobility of the cable stress relief device in the pre-assembled state at least in the axial direction (or along the assembly direction or against the assembly direction).

[0095] Advantageously, by combining the cable stress relief device and the termination cap to form a common termination assembly, the number of work steps that cable connector manufacturers or assemblers need to perform can be reduced, which reduces assembly time and assembly costs. This advantageously combines at least two assembly steps together.

[0096] Within the scope of the proposed method for assembling cable connector arrangements, in principle, any other desired method steps can also be provided (in a correspondingly suitable order), particularly for example: - Equip the cable with termination components and connector housings and / or additional connector components (i.e., insert the cable into termination caps, cable stress relief devices and connector housings). - At least partially strip the outer sheath of the cable; - Install the contact element on the electrical conductor of the cable; - Install the support sleeve onto the cable; - Processing the braided cable shield of the cable, for example, folding the braided cable shield onto a support sleeve; - Pressing or crimping the outer conductor against or onto the braided cable shield and / or support sleeve; and - Other methodological steps conventional in the art within the context of connector assembly.

[0097] It should be emphasized that the method steps for assembling cable connector arrangements do not necessarily have to be performed in the order they are first described or mentioned in the specification or claims. Therefore, for example, if not technically excluded, individual method steps or groups of method steps can be interchanged. Individual method steps can also be combined, divided into independent intermediate steps, or supplemented by intermediate steps. The method is not necessarily described exhaustively by the method steps described below, and can be supplemented by other method steps (including those not mentioned).

[0098] This termination component advantageously has two positions or two states: - The pre-assembled state or pre-assembled position of the cable stress relief device in the termination cap, especially in the delivered state; and - The final assembly state or end position of the cable stress relief device in the termination cap when the termination cap is fully installed on the connector housing.

[0099] The final assembly state can be achieved, for example, by the connector housing opening the corresponding latching tabs of the termination cap, thereby (at least temporarily) allowing the cable stress relief device to move within the termination cap. Subsequently, the cable stress relief device can be moved directly or indirectly by means of the connector housing until it is secured to the cable within the termination cap (preferably, but not necessarily, the "end position"). Preferably, in its end position, the cable stress relief device is fully engaged with the cable, particularly the cable sheath, to secure the cable relative to the connector housing according to its intended function.

[0100] The present invention also relates to an apparatus for assembling cable connector arrangements, particularly for high-voltage technology cable connector arrangements, the apparatus being configured to perform the methods according to the embodiments described above and below.

[0101] The features described in conjunction with one of the subjects of the invention (specifically given by the termination assembly according to the invention, the cable connector arrangement according to the invention, the method according to the invention, and the device according to the invention) can also be advantageously implemented for other subjects of the invention. Similarly, the advantages mentioned in conjunction with one of the subjects of the invention can also be understood to relate to other subjects of the invention.

[0102] Furthermore, it should be noted that expressions such as "comprising," "having," or "with" do not exclude any other features or steps. Additionally, expressions such as "a," "an," or "the," referring to a single step or feature, do not exclude multiple features or steps, and vice versa.

[0103] However, in pure embodiments of the invention, it may also be configured such that a comprehensive list of features is constituted by the terms "comprising," "having," or "with." Therefore, within the scope of the invention, one or more lists of features may be considered independently complete, for example, with respect to each claim. For instance, the invention may consist exclusively of only the features described in claim 1.

[0104] It should be mentioned that designations such as "first" or "second" are primarily used to distinguish the corresponding features of the equipment or method, and are not necessarily intended to indicate that the features require or are related to each other.

[0105] It should also be emphasized that the values ​​and parameters described herein include deviations or fluctuations of ±10% or less, preferably ±5% or less, more preferably ±1% or less, and extremely preferably ±0.1% or less from the values ​​or parameters mentioned, provided that such deviations are not excluded in the practice of this invention. The limitation of the range by the starting and ending values ​​also includes all numerical values ​​and fractions contained within the correspondingly mentioned ranges, particularly the starting and ending values ​​and their corresponding averages.

[0106] The present invention also relates to a separate termination cap for a termination assembly, which in particular (but not necessarily) is the termination assembly claimed in claim 1, wherein the termination cap can be mounted on the cable-side end of a connector housing, and wherein, in a pre-assembled state where the termination cap is not mechanically connected to the connector housing, the termination cap can be securely connected to a separate cable stress relief device, and wherein the termination cap is designed such that, during the mounting of the termination cap to the connector housing, the cable stress relief device is movable from the connector housing toward the cable-side end of the termination cap.

[0107] Furthermore, the present invention also relates to a separate cable stress relief device for a termination assembly, the termination assembly being particularly (but not necessarily) the termination assembly claimed in claim 1, wherein the cable stress relief device can be fastened to the cable on which the cable connector is arranged, and wherein, in a pre-assembled state where the cable stress relief device is not mechanically connected to the cable, the cable stress relief device can be securely connected to a separate termination cap, and wherein the cable stress relief device is designed to move from the connector housing toward the cable-side end of the termination cap during the installation of the termination cap onto the connector housing.

[0108] Further features of claim 1 and the dependent claims, as well as the features described in the specification, relate to advantageous embodiments and variations of the aforementioned separate termination cap and separate cable stress relief device. The applicant expressly reserves the right to separately claim protection for the separate termination cap and / or the separate cable stress relief device in each case. Attached Figure Description

Detailed Implementation

[0113] Figures 1 to 6 A first exemplary embodiment of the present invention is shown as an example. Figures 1 to 3 It shows in Figures 4 to 6 The termination assembly 1 of the cable connector arrangement 2 is shown in more detail below.

[0114] Termination assembly 1 includes termination cap 3 and cable stress relief device 4, each of which is located in...Figure 1 They are shown separately in a state where they are not yet connected to each other. In contrast, Figure 2 and Figure 3 The pre-assembled state of the termination assembly 1 is shown, in which the cable stress relief device 4 is connected to the termination cap 3 in a non-detachable manner.

[0115] The termination cap 3 can be mounted on the cable-side end 5 of the connector housing 6 of the cable connector arrangement 2, as also described below. In short, the termination cap 3 according to the described exemplary embodiment can be latched onto the connector housing 6.

[0116] In addition, the cable stress relief device 4 can be fastened to the cable 7 of the cable connector arrangement 2, which will also be described in more detail below.

[0117] It should be mentioned here that, Figures 4 to 6 The cable 7, connector housing 6, and all other components of the cable connector arrangement 2 shown should be understood as merely exemplary and illustrative. In principle, the invention can be advantageously applied to any type of cable and connector.

[0118] exist Figure 2 and Figure 3 In the pre-assembled state of the termination assembly 1 shown, the termination cap 3 is not yet mechanically connected to the connector housing 6, and the cable stress relief device 4 is not yet mechanically connected to the cable 7. This pre-assembled state can be, for example, the delivery state, on which assemblers or equipment subsequently mechanically connect the termination assembly 1 to the cable 7 and the connector housing 6.

[0119] In an exemplary embodiment, the termination cap 3 and the cable stress relief device 4 are both sleeve-shaped and each has a cable pass-through portion 8 for the cable 7. The cable stress relief device 4 is housed within the termination cap 3.

[0120] The cable stress relief device 4 has at least one connecting device, or a lateral extension 9 (in Figures 1 to 1 In the exemplary embodiment of 2a, there are exactly two lateral extensions 9, which are spaced apart from each other in the circumferential direction U, or arranged on opposite circumferential sections of the cable stress relief device 4, among others, see [link to relevant documentation]. Figure 3 In the pre-assembled state of the termination assembly 1, the lateral extension 9 is engaged with the termination cap 3 (see in particular). Figure 2 and Figure 3 This limits the mobility of the cable stress relief device 4 in the axial direction A. Therefore, in Figures 1 to 1In the exemplary embodiment of 2a, the lateral extension 9 of the cable stress relief device 4 engages within various mating connection devices or elongated holes 10 in the sidewall 11 of the termination cap 3. It should be noted that the housing wall of the termination cap 3 does not necessarily need to have elongated holes 10, nor does it necessarily need to have through holes—square, circular, or other recesses and / or recesses (e.g., grooves in the sidewall 11) can be used instead of full through holes, or protrusions (e.g., webs or ribs for providing guide channels) can be provided on the inner housing. Furthermore, it should be emphasized that the connection device of the cable stress relief device 4 can optionally be designed as a recess or elongated hole, and the mating connection device of the termination cap 3 can be designed as a lateral extension. Therefore, the variations shown in the figures should be understood as merely exemplary.

[0121] Due to the specific distribution or arrangement of the connecting device 9 and the mating connecting device 10 along the circumference of the termination cap 3 and the cable stress relief device 4, anti-rotation devices and / or mechanical coding can optionally be provided to ensure that the cable stress relief device 4 can only be installed in the termination cap 3 in a single orientation or in a specific predetermined orientation (this also applies to installing the connector housing 6 on the termination cap 3).

[0122] In an exemplary embodiment, the lateral extension 9 is received without clearance in the elongated hole 10 in the circumferential direction U to prevent relative rotation of the cable stress relief device 4 in the termination cap 3—however, this is not absolutely necessary. Furthermore, the cable stress relief device 4 is also received without clearance in the lateral or radial direction R within the termination cap 3—this is advantageous, but not absolutely necessary.

[0123] To limit movement in the axial direction A, the lateral extension 9 has a blocking surface 9' on its side facing the connector-side end section 12. This blocking surface abuts against a corresponding mating blocking surface 10' of the elongated hole 10. This mating blocking surface 10' is formed on the connector-side inner surface of the elongated hole 10 (see, among others). Figure 1 and Figure 6 ).

[0124] In addition to the movement restriction provided by the combination of the lateral extension 9 and the elongated hole 10, the exemplary embodiment also includes: in the pre-assembled state, the cable stress relief device 4 is locked at the pre-assembled position P0 in the connector-side end section 12 of the termination cap 3 (see...). Figures 2 to 4Therefore, in the pre-assembled state, the cable stress relief device 4 is preferably lockable completely immovably or at least substantially immovably at the pre-assembled position P0. This locking is preferably achieved by at least one locking device formed in the termination assembly 1. In this regard, in the exemplary embodiment, two pairs of latch lugs 13 are provided, the same pair of latch lugs 13 being laterally arranged beside the elongated hole 10 and opposite to each other. The latch lugs 13 can be locked using the flange section 14 of the cable stress relief device 4 or other suitable housing side structure. In principle, any number of locking devices or latch lugs 13 can be provided, or only a single locking device or latch lug 13 may be provided. In the case of multiple locking devices or latch lugs 13, these locking devices or latch lugs 13 can advantageously be distributed on the sidewall 11 of the termination cap 3 and spaced apart from each other in the circumferential direction.

[0125] To achieve the latching between the termination cap 3 and the connector housing 6 mentioned above, the termination cap 3 has at least one latching device for latching with a corresponding mating latching device of the connector housing 6. In an exemplary embodiment, two latching devices or mating latching devices spaced apart from each other in the circumferential direction are provided in each case. The latching device of the termination cap 3 is a latching tab 15, which is resilient in the lateral or radial direction R and has a latching recess 16. The mating latching device is designed, for example, as a latching protrusion of the connector housing 6 (e.g., a latching arm 17), and is capable of latching within the latching recess 16 of the latching tab 15 (see...). Figure 6 However, it can also be configured such that the latching tab 15 or latching device of the end cap 3 has a latching protrusion, while the mating latching device of the connector housing 6 has a latching recess.

[0126] Particularly advantageously, the recess or elongated hole 10 for connection to the lateral extension 9 of the cable stress relief device 4 corresponds, in the present case, to the latching recess 16 for the mating latching device or latching arm 17 of the connector housing 6, as shown in the exemplary embodiment. Typically, the latching tab 15 of the end cap 3 is provided with a mating connection device 10 (i.e., the recess or elongated hole 10 or the lateral extension) to provide the advantageous dual function of pre-fixing and final latching position. To provide lateral or radial elasticity of the latching tab 15, longitudinal grooves 18 are provided in the sidewall of the end cap 3, on both sides of the latching tab 15.

[0127] Within the scope of this invention, a cable stress relief device 4 is provided that, during the installation of the termination cap 3 onto the connector housing 6, can be moved from the connector housing 6 toward the cable-side end 19 of the termination cap 3 (which faces away from the connector housing 6). (Comparison) Figure 5 andFigure 6 This movement can be clearly seen, and this movement can be aided by the axial guiding function of the elongated hole 10.

[0128] As described above, the cable stress relief device 4 is preferably locked in the pre-assembled state or pre-assembled position P0. During the installation of the termination assembly 1 onto the connector housing 6, this locking can be released by the connector housing 6 to initially allow the cable stress relief device 4 to move from the pre-assembled position P0 toward the cable-side end 19 of the termination cap 3. This process... Figure 5 The example is shown in the middle.

[0129] In an exemplary embodiment, the mating latching device or latching arm 17 of the connector housing 6 is used to lift the latching tab 15, thereby simultaneously lifting the latching lug 13 of the end cap 3 arranged next to the elongated hole 10, thus releasing the locking of the cable stress relief device 4. Subsequently, in further assembly, the cable stress relief device 4 is further moved by the connector housing 6 (e.g., by the mating latching device or latching arm 17) in the axial direction A until the cable stress relief device 4 reaches the end position P1 located at the cable-side end section of the end cap 3 (see [link to documentation]). Figure 5 and Figure 6 At the end position P1, the cable stress relief device 4 is fixed to the cable 7 by force engagement.

[0130] In order to secure the cable stress relief device 4 to the cable 7, the cable stress relief device 4 has fixing tabs 20, which are arranged circumferentially in an exemplary embodiment and are pressed against the cable sheath 21 of the cable 7 with increased clamping force due to mechanical interaction with the termination cap 3 during the cable stress relief device 4 moving to the end position P1.

[0131] Figures 4 to 6 Also shown as an example is the cable seal 22 within the connector housing 6, which, as another component of the cable connector arrangement 2, can be omitted as an alternative, or as described below. Figure 7 As shown, it can be optionally provided as a component of termination assembly 1.

[0132] Figure 7 A variation of the invention is shown (as an example). Figure 7 The exemplary embodiments shown in principle correspond to Figures 1 to 6 (Exemplary embodiment), to illustrate by way of example that, in the pre-assembled state of the termination assembly 1, the cable seal 22 can also be securely connected to the termination cap 3 and / or the cable stress relief device 4, for example, by form fit, force fit, and / or material bonding. Figure 7In this process, the cable seal 22 is fastened, for example, to the connector side end face of the cable stress relief device 4 (e.g., by overmolding in the context of a two-component process).

[0133] Advantageously, it can therefore be set within the scope of the method for assembling the cable connector arrangement 2: firstly, the cable 7 and the connector housing 6 are provided (in this case, it can also be optionally set to first pre-treat the cable 7, for example, partially stripping the insulation layer and equipping it with one or more components of the cable connector arrangement 2, i.e., the connector housing 6 or the termination assembly 1).

[0134] During assembly, the termination assembly 1 can advantageously be considered as a single component, since the termination cap 3 and the cable stress relief device 4 (along with other optional connector components, such as the cable seal 22) are already securely connected to each other in a pre-assembled state. Therefore, assembly can be particularly simple for the assembler or the assembly equipment. The termination cap 3 can be mounted on the connector housing 6 while the cable stress relief device 4 is moved from the connector housing 6 toward the cable-side end 19 of the termination cap 3 (which faces away from the connector housing 6), wherein the cable stress relief device 4 is preferably fastened to the cable 7 at the same time.

[0135] It should also be mentioned that, in conjunction with the latching connection, threaded connections or essentially any desired fastening technique for securing the termination cap 3 to the connector housing 6 can also be considered; that is, for example, the termination cap 3 can also be press-fitted onto the connector housing 6. Therefore, in principle, different fastening techniques can also be combined within the scope of the invention. The basic core is that the cable stress relief device 4 is securely connected to the termination cap 3 in a pre-assembled state and, during assembly, can be moved indirectly or directly toward the cable-side end 19 of the termination cap 3 by the connector housing 6 or another component of the cable connector arrangement 2.
