Description

[0001] The invention relates to a termination assembly of a cable connector assembly, comprising a termination cap mountable on a cable-side end of a connector housing of the cable connector assembly and a cable strain relief mountable on a cable of the cable connector assembly.

[0002] The invention also relates to a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology, comprising a termination assembly.

[0003] The invention further relates to a method for assembling a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology.

[0004] Cable connectors are essential components in numerous electronic devices and systems of various designs. They are designed to provide a reliable electrical connection between the components involved and serve to transmit electrical power and / or data signals to corresponding mating connectors. Typical applications include the interconnection of electronic assemblies in computers, communications devices, automobiles, and many other areas.

[0005] When assembling a cable connector on a cable, a key challenge is to assemble a large number of components of the cable connector on the cable, as described, for example, in DE 10 2014 200 133 A1 in the Figures 1 and 2 shown.

[0006] One connector component that must regularly be installed in the cable entry area (also known as "cable exit" or "cable feedthrough") is a so-called "end cap," which is usually attached to the cable-side end of the connector housing as the last connector component. A cable strain relief device must also be regularly installed in the cable-side end section of the cable connector to prevent the cable from being pulled out or released uncontrollably from the cable connector. Finally, cable and / or housing seals are sometimes installed in the cable exit area. This list is not exhaustive.

[0007] The assembly effort for a cable connector can be correspondingly high and often requires careful and time-consuming assembly by trained specialists or complex assembly equipment. The assembly of the individual connector components is therefore a factor that significantly influences the cost-effectiveness of mass production of a cable connector, and there is a need to improve the efficiency of this process to achieve time and cost savings in connector assembly.

[0008] In view of the known prior art, the object of the present invention is to provide a termination assembly of a cable connector assembly and a cable connector assembly which can preferably be mounted on a cable in a particularly simple and economical manner.

[0009] The present invention is also based on the object of providing a method for assembling a cable connector arrangement, by means of which a termination module of a cable connector arrangement can preferably be mounted on a cable in a particularly simple and economical manner.

[0010] The object is achieved for the termination assembly with the features listed in claim 1. With regard to the cable connector assembly, the object is achieved by the features of claim 14 and with regard to the method by claim 15.

[0011] The dependent claims and the features described below relate to advantageous embodiments and variants of the invention.

[0012] The invention relates to a termination assembly of a cable connector assembly, comprising a termination cap mountable on a cable-side end of a connector housing of the cable connector assembly and a cable strain relief mountable on a cable of the cable connector assembly.

[0013] Preferably, the cable connector assembly, connector housing, cable connector, and cable are not to be considered part of the claimed termination assembly. However, the applicant reserves the right to claim various combinations of termination assembly, cable connector assembly, connector housing, cable connector, and cable, or each of the aforementioned items individually or separately.

[0014] The cable can, in particular, be an electrical or optical cable of any design (e.g., the cable can be single-core, multi-core, coaxial, with twisted pairs, etc.). The cable typically has a cable sheath that encloses the internal cable components, such as one or more cable cores and / or a cable shield. The cable strain relief device can preferably be attached to the cable sheath, preferably at a cable end section.

[0015] The cable connector is, in particular, an electrical or optical cable connector, again of any design. It can preferably be a high-voltage connector for transmitting voltages and currents for high-voltage technology. However, the invention can also be used with a data connector for transmitting data signals, for example.

[0016] The termination assembly or its individual components, the connector housing and the cable seal mentioned below, as well as any other components, such as a support sleeve or one or more contact elements, may also be referred to below as "connector components" of the cable connector.

[0017] According to the invention, the cable strain relief device is captively connected to the end cap in a pre-assembled state of the termination assembly in which the end cap is not mechanically connected to the connector housing.

[0018] Because the cable strain relief device is already captively connected to the end cap in the pre-assembled state, i.e. in the not yet assembled state of the termination module and thus, for example, in the delivery state of the termination module, it is possible to handle the end cap and the cable strain relief device as a common component during connector assembly, which can reduce the assembly effort (and thus also the assembly time) and the susceptibility to errors during connector assembly.

[0019] The aforementioned "captive connection" can preferably be a positive connection between the cable strain relief and the end cap, in particular (but not exclusively) as described below. In principle, however, it can be any mechanical connection that ensures that the cable strain relief and the end cap cannot be accidentally separated before the end cap is installed on the connector housing. For example, it can alternatively or additionally be a material-to-material and / or force-fit connection.

[0020] A material-to-material connection can be provided, for example, by one or more welded or glued points applied between the cable strain relief device and the end cap during pre-assembly or manufacture of the cable strain relief device and the end cap, in particular in such a way that the material-to-material connection (e.g. the welded or glued point) can be released again during assembly (e.g. in the manner of a predetermined breaking point).

[0021] A one-piece design of the cable strain relief device and the end cap can also be provided if necessary in order to enable the captive connection in the pre-assembled state, for example by means of a movable connection between the cable strain relief device and the end cap, inter alia using at least one film hinge.

[0022] An initially immovable connection between the cable strain relief device and the end cap via one or more predetermined breaking points can also be provided, so that the cable strain relief device and the end cap can initially be manufactured and delivered together, with the predetermined breaking point then being broken by the assembly of the end cap on the connector housing or even beforehand deliberately by the fitter or an assembly device.

[0023] A force-fit connection between the cable clamp and the end cap can also be provided to ensure a captive connection during pre-assembly. For this purpose, the cable clamp can be pressed into the end cap during pre-assembly, optionally with increased frictional engagement (e.g., by roughening the cable clamp and / or end cap on the casing).

[0024] Combinations of different connection techniques are also explicitly possible within the scope of the invention.

[0025] As already mentioned, the invention is described below essentially on the basis of a purely positive, captive connection between the cable strain relief and the end cap in the pre-assembled state, which, however, is not to be understood as limiting.

[0026] According to the invention, the cable strain relief device can be moved from the connector housing in the direction of a cable-side end (in particular an end facing away from the connector housing) of the end cap during assembly of the end cap to the connector housing.

[0027] The fact that the cable strain relief device can be moved "independently" within the end cap during assembly through the connector housing and thus moved to its final position within the end cap further simplifies the assembly of these two connector components. An installer or a device for assembling the cable connector assembly therefore only needs to install the end cap, which simultaneously installs the cable strain relief device, without requiring a separate assembly step.

[0028] To enable the movement of the cable tension protection device through the connector housing during assembly, it can be provided, in particular, that an end face of the cable tension protection device facing the connector housing and / or an actuating surface formed on the inner and / or outer shell sides of the cable tension protection device is accessible from the connector-side end of the end cap. In this way, the connector housing (or at least a portion of the connector housing) can directly or indirectly contact the actuating surface and thus cause the movement of the cable tension protection device.

[0029] In an advantageous development of the invention, it can be provided that the end cap and the cable tension protection are each ring-shaped or sleeve-shaped and each have a cable feedthrough for the cable.

[0030] The side walls of the end cap and / or cable strain relief device can have any slits (e.g. longitudinal slits) or other recesses / depressions and / or elevations.

[0031] In principle (in a less preferred embodiment), it can also be provided that the end cap and / or the cable strain relief device are partially annular or formed as a continuously slotted sleeve. For example, a longitudinal slot extending completely through the end cap or cable strain relief device in the axial direction can be provided. Preferably, however, the end cap and / or the cable strain relief device are completely annular or circumferentially closed at least in one axial section (e.g., in a flange-like end section).

[0032] At this point, it should be noted that the termination assembly, cable strain relief device, and / or end cap do not necessarily have to be (hollow) cylindrical, but can, in principle, have any cross-sectional geometry. Thus, for example, rectangular or other cross-sectional geometries are also conceivable, although the invention will be described below essentially with reference to hollow cylindrical cross-sectional geometries. However, this is intended solely to facilitate understanding of the invention and not to limit the claimed subject matter to an at least essentially round cross-sectional geometry. Therefore, if the terms "radial" or "round," etc., are used below, these can be generalized or substituted by the person skilled in the art with corresponding terms that also refer to or include other cross-sectional geometries.

[0033] The cable strain relief is preferably accommodated at least in sections within the end cap.

[0034] According to a further development of the invention, it can be provided that the mobility of the cable tension protection device in the pre-assembled state, when the cable tension protection device is captively connected to the end cap, is limited at least in the axial direction.

[0035] Limited mobility of the cable strain relief device, at least in the axial direction, means that movement may indeed be possible in the axial direction, but that this movement may be limited between a pre-assembly position and an end position, wherein the pre-assembly position is preferably arranged closer to the connector-side end of the end cap than the end position.

[0036] Preferably, the cable tension protection device has at least one connecting means and the end cap has at least one counter-connecting means in order to limit the mobility (at least in the axial direction).

[0037] The connecting means and the counter-connecting means are preferably designed for this purpose and arranged on the cable tension protection device and the end cap in such a way that the connecting means is mechanically blocked by the counter-connecting means (i.e., abuts against the counter-connecting means) - or vice versa. In particular, by the connecting means and the counter-connecting means abutting against each other at least at a defined stop position during the mutual movement of the cable tension protection device and the end cap in the axial direction, said movement limitation in the axial direction can be provided.

[0038] Preferably, the connecting means has at least one blocking surface and the counter-connecting means has at least one counter-blocking surface, which can abut against one another to limit the mobility of the cable tension protection device in the pre-assembled state. The blocking and counter-blocking surfaces can, in principle, be of any desired design, in particular primarily flat, but optionally also concave / convex or otherwise curved. Alternatively or in addition to blocking and counter-blocking surfaces, a (counter-)blocking tip, a (counter-)blocking edge, or another structure usable as a stop can also be provided, in particular combinations of the aforementioned variants. It should also be mentioned that, if necessary, several blocking surfaces can abut against a common counter-blocking surface – or vice versa.

[0039] Preferably, a surface vector of the blocking surface and / or a surface vector of the counter-blocking surface runs at least substantially in the axial direction or in or opposite to the mounting direction of the cable strain relief device in the end cap. However, the surface vectors can also run, for example, in the radial direction, preferably transversely or orthogonally to the axial / mounting direction. Preferably, the surface vector of the blocking surface runs opposite to the surface vector of the counter-blocking surface. Blocking and / or counter-blocking surfaces oriented obliquely to the longitudinal axis of the cable strain relief device or to the axial direction (e.g., conical blocking / counter-blocking surfaces) are also possible in principle.

[0040] It can be provided that the blocking / counter-blocking surface is formed on the side surfaces of the lateral extensions mentioned below and / or on flags, pins, webs, ribs, flange-shaped sections or the like.

[0041] The blocking / counter-blocking surface can be end surfaces, side surfaces and / or inner surfaces of a recess.

[0042] The blocking / counter-blocking surfaces can extend completely circumferentially, in particular if they are formed on a flange-shaped section of the end cap or the cable tension protection device, or only along an inner or outer circumferential segment, in particular if they are formed on the lateral extensions, flags or the like.

[0043] According to a further development of the invention, it can be provided that the at least one connecting means of the cable tension protection device is in engagement with the at least one counter-connecting means of the end cap in the pre-assembled state of the end module in order to limit the mobility of the cable tension protection device at least in the axial direction.

[0044] Preferably, at least two of said connecting means are provided, which are arranged spaced apart from one another in the circumferential direction and / or in the axial direction. For example, three, four, five, six, or even more connecting means can also be provided and distributed along the circumference and / or the longitudinal extent of the cable tension protection device, in particular spaced equidistantly. If exactly two connecting means are provided, they can preferably be arranged opposite one another circumferentially or in the circumferential direction, or offset by 180° from one another.

[0045] According to a further development of the invention, the connecting means of the cable tension protection device can be designed as a lateral extension, and the mating connecting means of the end cap can be designed as a receptacle for the lateral extension. The blocking surfaces can then be formed, for example, laterally on the lateral extensions, and the counter-blocking surfaces on the inner surfaces of the receptacle, so that the blocking surfaces can abut with their lateral surfaces on regions of the inner surfaces of the lateral extension that serve as end stops (i.e., for example, on opposite ends of an elongated recess mentioned below).

[0046] It should also be emphasized that it can also be provided that the counter-connecting means of the end cap having the counter-blocking surface is designed as a lateral extension and the connecting means of the cable tension protection having the blocking surface is designed as a receptacle for the lateral extension.

[0047] Preferably, the at least one receptacle for the at least one lateral extension is a recess, in particular one or more openings in the side wall of the end cap (i.e., for example, a through-hole or a window-shaped opening). Optionally, the recesses may also be depressions in the side wall (i.e., for example, a blind hole or a groove). Alternatively, the at least one receptacle for the at least one lateral extension may also be one or more steps, edges, webs, ribs, grooves, or other suitable counter-connecting means to provide the desired movement limitation.

[0048] Preferably, said recesses are elongated recesses (hereinafter: "slots"), in particular elongated holes extending in the axial direction, particularly preferably elongated holes extending in a straight line in the axial direction. Preferably, the at least one elongated hole extends in the axial direction at least between the aforementioned pre-assembly position and the final position, or at least it can be provided that the longitudinal extent of the elongated hole corresponds at least to the distance between the pre-assembly position and the final position.

[0049] At this point, it should be mentioned that the mobility of the cable tension safety device can also be at least limited in the lateral or radial direction and / or rotationally or circumferentially. A rotational movement limitation can also be achieved, in particular, by the at least one lateral extension, which engages with the end cap, so that rotation of the cable tension safety device and end cap relative to each other (i.e., movement in the circumferential direction) is only possible to a limited extent or is completely locked.Radial movement limitation can be achieved in particular by arranging the cable tension protection device within the (preferably sleeve-shaped) end cap, so that the lateral mobility can be defined and adjusted by a potential play between the external dimensions of the cable tension protection device and the internal dimensions of the end cap in the assembled state (i.e., in particular, by the difference between the external diameter of the cable tension protection device and the internal diameter of the end cap). Preferably, the cable tension protection device is accommodated within the end cap at least approximately or completely free of play with respect to twisting or movement in the circumferential direction and / or movement in the lateral or radial direction.

[0050] In a further development of the invention, it can be provided that the counter-connecting means, in particular the elongated holes, form a guide function for the movement of the connecting means (and thus of the entire cable tension protection device) in the direction of the cable-side end of the end cap.

[0051] In particular, the elongated design of the recesses allows the lateral extensions to be guided in a defined manner along their longitudinal extent. Thus, the movement of the cable strain relief device toward the cable-side end of the end cap can be specified along a defined path during assembly of the end cap. This is preferably, but not necessarily, a linear guide in the axial direction. In principle, however, any desired guide can be provided through the recesses, for example, a curved path that, in addition to an axial movement, also describes a rotation in the circumferential direction through a defined angular section.

[0052] At this point it should be emphasized that a guide function for the cable tension protection or its lateral extensions through the recesses is advantageous, but not absolutely necessary within the scope of the invention.

[0053] Furthermore, it should be mentioned that the distribution of the lateral extensions on the cable strain relief device and the recesses on the end cap can also be reversed, so that the end cap has the at least one lateral extension and the cable strain relief device has the at least one (elongated) recess or elongated hole. Furthermore, it can also be provided that a recess is completely omitted if, for example, the cable strain relief device is supported on an inner surface of the end cap at at least two positions along the axial direction (e.g. by at least two lateral extensions being arranged offset from one another in the axial direction). Furthermore, a lateral extension and a recess can also be omitted altogether if the outer surface of the cable strain relief device is guided directly along the inner surface of the end cap.

[0054] In general, it can therefore be provided that the cable tension protection device has at least one connecting means (e.g. the lateral extension) and the end cap has at least one counter-connecting means (e.g. the recess), which can be connected to one another in order to effect the described movement limitation at least in the pre-locking position.

[0055] In a further development of the invention, it can be provided that the cable tension protection is locked in the pre-assembled state of the termination module in a pre-assembled position within the termination cap, in particular in a connector-side end section of the termination cap.

[0056] Said locking can preferably be effected by at least one locking means formed in the closure assembly.

[0057] The locking mechanism allows the mobility of the cable strain relief device in the pre-assembled state within the end cap to be not only limited but also clearly defined (particularly in the axial direction, but preferably also in the lateral or radial direction and / or in the circumferential direction). A correspondingly locked position can further simplify assembly, as the cable strain relief device is thus in a known and defined state, at least at the beginning of assembly.

[0058] The locking means can preferably be a locking lug or another elevation on the inner surface of the end cap in order to form a stop for the cable tension safety device, in particular a stop for an end face, for example a flange-shaped end face of the cable tension safety device (alternatively, however, the cable tension safety device can also have the elevations, for example locking lugs, and the end cap can have the stop, for example a recess).

[0059] Preferably, at least two locking means can be provided on the end cap, which are arranged circumferentially spaced from one another, for example, arranged circumferentially opposite one another. In principle, any number of corresponding locking means can be provided, for example, two, three, four, five, six, or even more locking means, which are circumferentially spaced from one another, for example, distributed equidistantly along the circumference.

[0060] The locking means can also be designed in pairs, for example, with a first pair of locking means (e.g., locking lugs) being arranged laterally next to the aforementioned recess, so that the recess, in particular the elongated hole, is located between the locking means of the common pair. In this case, for example, each of said recesses can preferably be laterally surrounded by a pair of locking means, which can be advantageous for the unlocking described below during assembly of the closure assembly.

[0061] In an advantageous development of the invention, it can be provided that the locking of the cable tension protection can be unlocked during the assembly of the termination assembly on the connector housing in order to release the mobility of the cable tension protection starting from the pre-assembly position in the direction of the cable-side end of the termination cap.

[0062] Unlocking can be done manually, for example using a tool, but preferably directly or indirectly through the connector housing.

[0063] In particular, it can thus be provided that at least one section of the connector housing is capable of unlocking the locking means during assembly (preferably a section of the connector housing leading in the assembly direction, such as the "counter-locking means" of the connector housing mentioned below).

[0064] The section of the end cap comprising the locking means can be elastically movable, in particular elastically deflectable / movable in the lateral or radial direction, so that the end cap can be at least temporarily spread open during assembly in order to release the locking by lifting the locking means. Alternatively or additionally, it can be provided that at least a section of the cable strain relief device is elastically movable, at least in the region of the locking means, in particular elastically deflectable / movable in the lateral or radial direction, so that the cable strain relief device can be at least temporarily compressed or pressed together during assembly in order to release the locking of the locking means.

[0065] The locking mechanism of the cable strain relief device can preferably be released non-destructively during assembly of the end cap to the connector housing (for example, through the elastic mobility of the section of the end cap containing the locking means, as described above). However, a destructive and thus generally permanent release, for example, by breaking off a predetermined breaking point or similar, can also be provided (less preferred). For example, the locking means / latch can also be broken off in a defined manner to release the cable strain relief device during assembly.

[0066] In a further development of the invention, it can be provided that the end cap can be locked to the connector housing at its connector-side end section.

[0067] For this purpose, the end cap can preferably have at least one locking means for locking with a respective counter-locking means of the connector housing, preferably at least two locking means spaced apart from one another on the circumference or even more locking means.

[0068] In an advantageous development of the invention, it can be provided that at least one of the locking means is designed as a locking tab which is elastic in a lateral direction (ie transversely, preferably orthogonally, to the axial direction), for example in the manner of a locking arm or a locking rocker.

[0069] The locking tab can have a locking hook or a similar locking elevation, but preferably a locking recess for a counter-locking means of the connector housing designed as a locking elevation (the locking tab can thus be U-shaped, for example).

[0070] In order to provide the elasticity of the locking means or the locking tab, it can be provided that a longitudinal slit or a longitudinal slot is formed in the side wall of the end cap on the circumference next to the respective locking means or the locking tab.

[0071] It should be noted at this point that the relationships can also be reversed. For example, it can also be provided that the at least one locking means is designed as a detent elevation and the at least one counter-locking means is designed as a locking tab. In particular, for example, one of the counter-locking means of the connector housing can be designed as a locking tab that is elastic in a lateral direction and preferably has a locking recess for a locking means of the end cap designed as a detent elevation. The features described above and below in this regard are therefore interchangeable between the end cap and the connector housing.

[0072] In an advantageous further development of the invention, it can be provided that the recess for the (positive-locking) connection with the lateral extension of the cable tension protection (in particular the elongated hole described above) corresponds to the locking recess for the counter-locking means of the connector housing.

[0073] In this way, the (elongated) recess or slot can advantageously fulfil a dual function and, on the one hand, provide a movement limitation (and optional guidance) for the cable tension protection and, on the other hand, a locking option for mounting on the connector housing.

[0074] Preferably, the end cap is secured to the connector housing by a snap-in connection, in particular by a snap-in connection as described above by way of example. However, a snap-in connection is only one of several options for mounting the end cap to the connector housing. Therefore, a threaded connection will be presented below as an exemplary alternative to the snap-in connection.

[0075] In an alternative advantageous development of the invention, it can therefore be provided that the end cap can be screwed to the connector housing at the end section on the connector side and for this purpose has a thread for screwing to a counter thread of the connector housing.

[0076] The thread of the end cap can preferably be an internal thread and the mating thread of the connector housing can be an external thread - or vice versa.

[0077] In a further development of the invention, it can be provided that the cable tension protection device is movable into a cable-side end section of the end cap during assembly of the end cap on the connector housing, preferably into an end position, in particular an end position in a cable-side end section of the end cap.

[0078] Preferably, the cable tension protection device is fixed to the cable in the cable-side end section, for example in the end position, in particular fixed in a force-locking manner.

[0079] It can be provided that the cable strain relief device is fixed in the end cap in the end position. This (in itself optional) fixing can be achieved, for example, by a latch between the cable strain relief device and the end cap in the end position. As a rule (but not absolutely necessary), the cable strain relief device can be fixed in the end position by the connector housing, by clamping the cable strain relief device between the connector housing and a stop in the end cap. The cable strain relief device is therefore preferably pressed in its end position by the connector housing (preferably by the counter-latching means of the connector housing or another section of the connector housing leading in the direction of assembly) against a stop formed on the cable-side end of the end cap, for example against a step.

[0080] The cable strain relief device can be provided with fixing tabs distributed around the circumference (optionally with fastening hooks arranged at the free ends). The fixing tabs can be elastic in the lateral or radial direction.

[0081] It can be provided that the fixing tabs, in their mechanically relaxed state, define an inner circumference that is smaller than an outer circumference of the cable, so that sliding them onto the cable causes mechanical tensioning of the fixing tabs, which leads to a force-fitting fastening on the cable. In addition or supplementary terms, it can also be provided that the fixing tabs are pressed against the cable with increasing pressing force through mechanical interaction with the end cap during movement of the cable tension protection device into the end position. For this purpose, it can be provided, for example, that the fixing tabs are pushed into an axial section of the end cap that tapers towards the cable-side end (e.g. a linear, curved and / or stepped taper).

[0082] It should be mentioned at this point that the movement of the cable strain relief device during assembly does not necessarily have to be carried out all the way to its end position, or at least not until it reaches a stop or other fixing point in the cable-side end section of the end cap. The movement of the cable strain relief device can, for example, already be limited by a sufficiently force-fitting fixation on the cable (sheath). It may therefore be sufficient to move the cable strain relief device towards the cable-side end of the end cap during assembly until the intended force-fitting fixation of the cable strain relief device on the cable (sheath) has been achieved. By remaining axial play towards the cable-side end of the end cap, tolerances can be compensated for and the termination assembly can even be used for different cable diameters.

[0083] In a further development of the invention, it can also be provided that the termination assembly in the pre-assembled state has, in addition to the cable tension protection, further captively connected connectors or other components, in particular a cable seal and / or housing seal captively connected to the end cap and / or the cable tension protection.

[0084] The other components, for example the cable seal and / or the housing seal, can be connected to the cable strain relief or the end cap in a materially bonded manner (preferred), a form-fitting manner and / or a force-fitting manner.

[0085] Preferably, an elastomer can be injection-molded onto the front side of the cable strain relief device (e.g., at the connector-side end) to form a seal (e.g., a cable seal). Thus, in particular, a two-component injection-molding process can be provided to firmly bond the remaining component to the cable strain relief device and / or end cap.

[0086] The fact that additional components are securely connected to the end cap can further simplify the assembly of the cable connector assembly.

[0087] The invention also relates to a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology, comprising a termination assembly according to the above and following embodiments, the connector housing and the cable, wherein the termination cap is mounted on the connector housing and the cable tension protection is fastened on the cable.

[0088] The captive fastening of the cable strain relief device to the end cap in the pre-assembled state and the subsequent "automatic" movement of the cable strain relief device towards the cable-side end in the end cap during assembly optimizes the overall assembly process, which can be particularly advantageous in mass production.

[0089] The cable connector assembly or termination assembly is particularly well-suited for use with high-voltage connectors, although the connector type and its application are not necessarily important. The cable connector assembly or termination assembly can therefore also be particularly well-suited for use in high-frequency technology, for example, for data connectors.

[0090] The invention also relates to a method for assembling a cable connector arrangement, in particular a cable connector arrangement for high-voltage technology, comprising at least the following method steps: Providing a cable and a connector housing; providing a termination assembly comprising a termination cap and a cable retention device captively connected to the termination cap; and mounting the termination cap to the connector housing while the cable retention device moves from the connector housing toward a cable-side end of the termination cap, and preferably is secured to the cable.

[0091] Advantageously, the work steps required by a cable connector assembler or installer can be reduced by combining the cable strain relief and end cap into a single termination assembly, reducing assembly time and costs. This advantageously combines at least two assembly steps.

[0092] Within the framework of the proposed method for assembling the cable connector assembly, any further process steps may in principle be provided (in a suitable order), such as in particular: the fitting of the cable with the termination assembly and the connector housing and / or other connector components (i.e., for example, inserting the cable into the termination cap, the cable strain relief and the connector housing); the stripping of the cable, at least in sections; the fitting of contact elements to electrical conductors of the cable; the fitting of a support sleeve on the cable; the processing of a cable braided shield, e.g., folding the cable braided shield over the support sleeve; the pressing or crimping of an outer conductor onto the cable braided shield and / or the support sleeve; as well as other standard process steps within the scope of connector assembly.

[0093] At this point, it should be emphasized that the method steps for assembling the cable connector assembly do not necessarily have to be performed in the order in which they are first described or mentioned in the description or in the patent claims. Therefore, for example, individual method steps or groups of method steps may be interchangeable, provided this is not technically impossible. Method steps may also be combined with one another, divided into separate intermediate steps, or supplemented with intermediate steps. The method is not necessarily described exhaustively with the method steps described below and may be supplemented with further method steps, even those not mentioned.

[0094] Advantageously, the termination assembly has two positions or two states: a pre-assembly state or a pre-assembly position of the cable strain relief in the end cap, in particular in the delivery state; and a final assembly state or a final position of the cable strain relief in the end cap when the end cap is fully mounted on the connector housing.

[0095] The final assembly state can be achieved, for example, by the connector housing spreading corresponding locking tabs of the end cap to thereby (at least temporarily) release the movement of the cable strain relief device within the end cap. The cable strain relief device can then be moved directly or indirectly by means of the connector housing into the position attached to the cable (preferably, but not necessarily, the "end position") within the end cap. In its end position, the cable strain relief device is preferably sufficiently engaged with the cable, in particular the cable sheath, to secure the cable to the connector housing in accordance with its intended function.

[0109] In the Figures 1 to 6 A first embodiment of the invention is shown by way of example. Figures 1 to 3 show the final assembly 1 of the Figures 4 to 6 cable connector arrangement shown in more detail 2.

[0110] The end assembly 1 has an end cap 3 and a cable strain relief 4, which are Figure 1 are shown separately in a state that is not yet connected to each other. Figures 2 and 3 a pre-assembled state of the end assembly 1, in which the cable strain relief 4 is captively connected to the end cap 3.

[0111] The end cap 3 can be mounted on a cable-side end 5 of a connector housing 6 of the cable connector assembly 2, as described below. Simply put, the end cap 3 can be locked to the connector housing 6 according to the first embodiment described above, and according to the second embodiment of the invention described below ( Figures 8 to 11 ) can be screwed to the connector housing 6.

[0112] Furthermore, the cable tension protection 4 can be fastened to a cable 7 of the cable connector arrangement 2, which will also be described in more detail below.

[0113] At this point it should be mentioned that the Figures 4 to 6The cable 7 shown, the connector housing 6, and all other components of the cable connector assembly 2 are to be understood merely as examples and schematically. In principle, the invention can be advantageously used with any type of cable and connector.

[0114] In the Figures 2 and 3 In the pre-assembly state of the termination assembly 1 shown, the end cap 3 is not yet mechanically connected to the connector housing 6, and the cable strain relief 4 is not yet mechanically connected to the cable 7. The pre-assembly state can, for example, be a delivery state, based on which an installer or a device subsequently mechanically connects the termination assembly 1 to the cable 7 and the connector housing 6.

[0115] In the exemplary embodiments, the end cap 3 and the cable strain relief device 4 are each sleeve-shaped and each have a cable feedthrough 8 for the cable 7. The cable strain relief device 4 is accommodated within the end cap 3.

[0116] The cable tension protection device 4 has at least one lateral extension 9 (in the embodiments of the Figures 1 to 12a exactly two lateral extensions 9, which are spaced apart from each other in the circumferential direction U or are arranged on opposite circumferential sections of the cable tension protection 4, cf. among others Figure 3 ). The lateral extensions 9 are in the pre-assembled state of the end assembly 1 in engagement with the end cap 3 (see in particular the Figures 2 and 3 ) in order to limit the mobility of the cable tension safety device 4 in the axial direction A. For this purpose, the lateral extensions 9 of the cable tension safety device 4 in the embodiments of the Figures 1 to 12ainto respective elongated holes 10 in the side wall 11 of the end cap 3. At this point, it should be mentioned that these do not necessarily have to be elongated holes 10, nor do they necessarily have to be openings in the housing wall of the end cap 3 - square, round, or other recesses and / or depressions (e.g., grooves in the side wall 11) as an alternative to a complete opening, or elevations on the inner casing side (e.g., webs or ribs to provide a guide channel) are also feasible.

[0117] In the exemplary embodiments, the lateral extensions 9 are accommodated in the elongated holes 10 without play in the circumferential direction U in order to prevent relative rotation of the cable strain relief device 4 in the end cap 3 – however, this is not absolutely necessary. Furthermore, the cable strain relief device 4 is also accommodated within the end cap 3 without play in the lateral direction or radial direction R – which is advantageous, but also not absolutely necessary.

[0118] To limit movement in the axial direction A, the lateral extensions 9 have blocking surfaces 9' on their sides facing the connector-side end section 12, which can strike against corresponding counter-blocking surfaces 10' of the elongated holes 10. The counter-blocking surfaces 10' are formed on the connector-side inner surfaces of the elongated holes 10 (cf., among others, Figures 1 and 6 ).

[0119] In addition to the movement limitation by the combination of lateral extensions 9 and elongated holes 10, it is also provided in the embodiments that the cable tension protection 4 in the pre-assembly state in the connector-side end section 12 of the end cap 3 in a pre-assembly position Po (cf. Figures 2 to 4) is locked. In the pre-assembled state, the cable pull protection device 4 can thus preferably be completely immobile or at least essentially immobile locked in the pre-assembly position Po. The locking can preferably be made possible by at least one locking means formed in the end module 1. In this regard, the exemplary embodiments provide two pairs of locking lugs 13, the locking lugs 13 of a common pair being arranged laterally next to the elongated holes 10, opposite one another. The locking lugs 13 can effect the locking with a flange section 14 or another suitable structure on the outer casing of the cable pull protection device 4. In principle, any number of locking means or locking lugs 13 can be provided, if necessary even just a single locking means or a single locking lug 13. Insofar as several locking means orIf locking lugs 13 are provided, these can advantageously be distributed circumferentially spaced from one another on the side wall 11 of the end cap 3.

[0120] For the aforementioned locking of the end cap 3 to the connector housing 6, the end cap 3 has at least one locking means for locking with a respective counter-locking means of the connector housing 6. In the exemplary embodiments, two locking means or counter-locking means are provided, spaced apart from one another on the circumference. The locking means of the end cap 3 is, for example, a locking tab 15 that is elastic in the lateral direction or radial direction R and has a locking recess 16. The counter-locking means is, for example, designed as a locking elevation of the connector housing 6, for example, locking arm 17, and is capable of locking within the locking recess 16 of the locking tab 15 (cf. Figure 6 ).

[0121] It can be particularly advantageous if the elongated holes 10 for connecting to the lateral extension 9 of the cable tension protection device 4 correspond to the locking recess 16 for the counter-locking means or the locking arm 17 of the connector housing 6, as shown in the exemplary embodiments. To provide the lateral or radial elasticity of the locking tab 15, longitudinal slots 18 are provided in the side wall of the end cap 3 on both sides of the locking tab 15.

[0122] Within the scope of the invention, it is provided that the cable tension protection 4 is movable during the assembly of the end cap 3 on the connector housing 6 from the connector housing 6 in the direction of a cable-side end 19 of the end cap 3 facing away from the connector housing 6. The movement is in a comparison of the Figures 5 and 6 clearly visible and can be supported by the axial guiding function of the elongated holes 10.

[0123] As already mentioned, the cable tension protection device 4 is preferably locked in the pre-assembly state or in the pre-assembly position Po. This locking device can be unlocked from the connector housing 6 during the assembly of the termination module 1 to the connector housing 6 in order to initially release the mobility of the cable tension protection device 4, starting from the pre-assembly position Po in the direction of the cable-side end 19 of the termination cap 3. This process is illustrated by way of example in Figure 5 shown.

[0124] In the exemplary embodiments, the counter-locking means or the locking arm 17 of the connector housing 6 serves to lift the locking tab 15 and thus simultaneously also the locking lugs 13 of the end cap 3 arranged next to the elongated hole 10, so that the locking of the cable tension protection device 4 is released. Subsequently, the cable tension protection device 4 is moved further in the axial direction A by the connector housing 6, for example by the counter-locking means or the locking arm 17, during the further assembly process until the cable tension protection device 4 reaches an end position P1 (cf. Figures 6 to 8 ) at a cable-side end section of the end cap 3. In the end position P 1, the cable tension protection device 4 is fixed force-fittingly on the cable 7.

[0125] For fixing the cable tension protection device 4 on the cable 7, the cable tension protection device 4 in the exemplary embodiments has fixing tabs 20 which are distributed circumferentially and which are pressed against the cable sheath 21 of the cable 7 with increasing pressing force by mechanical interaction with the end cap 3 during the movement of the cable tension protection device 4 into the end position P 1.

[0126] In the Figures 4 to 6 Within the connector housing 6, a cable seal 22 is shown as an example as a further component of the cable connector arrangement 2, which can alternatively also be omitted or can optionally be provided as a component of the termination assembly 1, as described in the following Figure 7 indicated.

[0127] Figure 7 illustrates a variant of the invention (for example, the one shown in Figure 7 The embodiment shown basically corresponds to the embodiment of the Figures 1 to 6) to illustrate by way of example that the cable seal 22 in the pre-assembled state of the termination assembly 1 can also be connected in a captive manner to the end cap 3 and / or the cable tension protection 4, for example in a form-fitting, force-fitting and / or material-fitting manner. Figure 7 The cable seal 22 is, for example, attached to the connector-side end face of the cable strain relief 4 (e.g., sprayed on in a two-component process).

[0128] Advantageously, within the scope of a method for assembling the cable connector assembly 2, it can thus be provided that the cable 7 and the connector housing 6 are first provided (optionally, it can also be provided that the cable 7 is first pre-processed, for example, partially stripped and equipped with one or more of the components of the cable connector assembly 2, for example, the connector housing 6 or the termination assembly 1).

[0129] During assembly, the termination assembly 1 can advantageously be treated as if it were only a single component, since the termination cap 3 and the cable strain relief device 4 (and optionally other connector components, such as the cable seal 22) are already captively connected to one another in the pre-assembled state. Assembly can therefore be particularly simple for the installer or an assembly device. The termination cap 3 can be mounted on the connector housing 6, while the cable strain relief device 4 is simultaneously moved by the connector housing 6 in the direction of the cable-side end 19 of the termination cap 3 facing away from the connector housing 6, wherein the cable strain relief device 4 is preferably attached to the cable 7 at the same time.

[0130] In the Figures 8 to 11A second embodiment of the invention is shown. The features of the second embodiment are essentially identical to those of the first embodiment, which is why the differences are essentially described below.

[0131] In contrast to the first embodiment, the end cap 3 in the second embodiment can be screwed to the connector housing 6 at the connector-side end section 12 instead of being latched. For this purpose, the end cap 3 has an internal thread 23 (cf. in particular the Figures 8 and 9 ), which is connected to a corresponding external thread 24 of the connector housing (see in particular the Figures 10 and 11 ) can be screwed. During screwing, the cable tension lock 4 is simultaneously moved in the axial direction A to the end position P 1 (cf. Figure 11 ).

[0132] In order to enable an initial screw connection between the end cap 3 and the connector housing 6, the cable strain relief device 4 is not fixed in its locked pre-assembled state to the connector-side end section 12 of the end cap 3, but rather to an axial position spaced apart from the connector-side end section 12. In the embodiment of the Figures 8 to 11 This is a middle axial section (see in particular Figure 9 ). For this purpose, the elongated hole 10 is shortened on the connector side so that the counter-blocking surface 10' is positioned closer to the axial center of the end cap 3.

[0133] At this point, it should also be mentioned that, as a further alternative to latching or screwing, any fastening technique for fastening the end cap 3 to the connector housing 6 can be considered, for example, pressing the end cap 3 onto the connector housing 6. Combinations of different fastening techniques are also fundamentally possible within the scope of the invention. What is essential is that the cable strain relief 4 is captively connected to the end cap 3 in the pre-assembled state and can be moved directly or indirectly in the direction of the cable-side end 19 of the end cap 3 during assembly by the connector housing 6 or another component of the cable connector arrangement 2.

[0134] Finally, based on the Figures 12a-12dSome variants for providing the mobility of the cable tension protection 4 within the end cap 3 in the sense of the present invention are compared by way of example.

[0135] Figure 12a shows schematically again the above-described combination of circumferentially spaced, lateral extensions 9 of the cable tension protection device 4, which are received in corresponding slots 10 of the end cap 3 and thus guided in the axial direction A. Preferably, the above-mentioned locking means or locking lugs 13 can also be provided in order to provide an axial positive connection in the pre-assembly position Po shown (in Figure 12a not shown).

[0136] The Figures 12b-12deach show variants of the invention without the use of elongated holes 10 for guiding the cable tension protection 4. The cable tension protection 4 is guided along the inner surface 11 of the end cap 3.

[0137] In order for the cable tension protection device 4 to be guided in a defined manner along the inner surface 11 (in particular in a tilt-proof manner), the cable tension protection device 4 can in turn have lateral extensions 9 offset in the circumferential direction U, which according to Figure 12bHowever, they are divided into two groups: a first group (for example, exactly two) of lateral extensions 9 in a connector-side end section and a second group (for example, again exactly two) of lateral extensions 9 arranged offset in the axial direction A in the direction of the cable-side end. Alternatively or in addition to said lateral extensions 9, the cable tension protection device 4 can also have flange-shaped circumferential extensions, which are worked out, for example, by a recess arranged therebetween. By way of example, optional locking means or locking lugs 13 for providing a stop in the pre-assembly position Po are also shown. It can also be provided that the end cap 3 has at least one lateral extension, which then, for example, with the in Figure 12bshown locking element 13 can be identical, and that the cable tension protection 4 has at least one receptacle for the lateral extension, for example an elongated hole in the manner shown in Figure 12b between the flange-shaped sections of the cable tension protection 4.

[0138] Based on Figure 12c It should be shown by way of example that even the lateral extensions 9 can be dispensed with within the scope of the invention if necessary. In order to further ensure advantageous guidance in the axial direction A, the axial extension of the outer surface of the cable tension protection device 4, which is connected to the inner surface 11 of the end cap 3, is designed to be correspondingly long. Optionally, in the variant according to Figure 12cLocking elements or locking lugs 13 may be provided (not shown) or another fixation of the cable pull protection 4 in the pre-assembly position Po, which can be released during assembly.

[0139] Figure 12d Finally, it should be made clear that in a less preferred embodiment, an extended contact surface between the cable strain relief 4 and the end cap 3 (as for example in Figure 12c ) is not absolutely necessary, insofar as tilting of the cable tension protection 4 in the end cap 3 is not absolutely important or if tilting is prevented in another way.
