Description

Technical Field

[0001] The present invention relates to a housing assembly for a plug connector according to the preamble of claim 1, the housing assembly having at least one first housing component for forming a cable sleeve through which a cable can be introduced into the interior of the housing assembly; and a cable sealing element for the cable, the cable sealing element being housed in the cable sleeve.

[0002] The present invention also relates to a plug connector, particularly an electrical plug connector having a housing assembly and at least one contact element capable of being connected to a cable.

[0003] The present invention also relates to a method for assembling plug connectors. Background Technology

[0004] Different electrical plug connectors are known in electrical engineering. As is well known, electrical plug connectors are used to transmit power and / or data signals to corresponding mating plug connectors. Plug connectors may include plugs, PCB connectors, built-in plugs, sleeves, couplings, or adapters. In the context of this invention, the term "plug connector" refers to all variations.

[0005] Among other things, increased requirements have been placed on the impermeability of plug connectors, particularly for the automotive industry and vehicles. Electrical plug connectors with cable sealing elements within the cable sheath of the plug connector housing are generally known. By way of example, refer to US 10,847,924B2 in this regard.

[0006] It has been shown that under certain mechanical loads (such as, for example, lateral tension on the cable), the impermeability of plug connectors equipped with cable sealing elements can be weakened. Due to the lateral load from the cable in the area of ​​the cable sheath, the cable sealing element can detach from the inner wall of the plug connector housing, thus allowing contaminants or liquids to penetrate.

[0007] The production of plug connectors with appropriate impermeability that meet all necessary standards and requirements is therefore extremely complex. This represents a conflict between the objective and a further critical requirement for plug connectors (especially those used in the automotive industry), which necessitates the ability to produce these plug connectors in large quantities at low cost. Summary of the Invention

[0008] In view of the prior art, the object of the present invention is to provide a housing assembly for a plug connector, which can preferably meet particularly high impermeability requirements by means of low-cost production and easy assembly.

[0009] The present invention is also based on the objective of providing a plug connector, particularly an electrical plug connector, which meets particularly high impermeability requirements by preferably being produced at low cost and being easy to assemble.

[0010] Another object of the present invention is to provide an advantageous method for assembling electrical plug connectors that meet high impermeability requirements.

[0011] The aforementioned objective is achieved by a housing assembly having the features listed in claim 1. In the case of a plug connector, this objective is achieved by the features of claim 14 and by the related method of claim 15.

[0012] The dependent claims and the features described below relate to advantageous embodiments and variations of the invention.

[0013] A housing assembly for a plug connector is provided, the housing assembly having at least one first housing component to form a cable sleeve (particularly a cable outlet and / or a cable inlet), through which a cable can be introduced into the interior of the housing assembly.

[0014] This invention is particularly suitable for use with electrical plug connectors. However, this should not be construed as limiting, as it is also possible to use it with optical plug connectors or other types of plug connectors.

[0015] The housing assembly preferably forms the plug connector housing of the plug connector and generally has at least one interior, which is at least substantially surrounded by the housing assembly in its assembled state, and the plug connector components of the plug connector can be housed in at least one interior and optionally fixed and connected to each other.

[0016] At least one housing component may have at least substantially tubular or sleeve-shaped portions to form a cable sheath, wherein the cable sheath has a generally at least partially straight profile along the intended feed or discharge direction for the cable (however, in principle, a curved or angled profile of the cable sheath may also be expected).

[0017] At least one housing component forming the cable sheath preferably has at least a partial inner surface, which can be used to support the cable sealing element referred to below. The inner surface may have a substantially planar profile; however, it may also have recesses and / or ridges, such as annular circumferential grooves or ribs, to secure the cable and / or cable sealing element in a form-fit manner in the assembled state of the housing assembly.

[0018] It should be mentioned here that the cable is preferably not part of the housing assembly for which protection is sought. However, the assembled cable may optionally be considered part of the housing assembly.

[0019] According to the invention, the housing assembly has a cable sealing element for the cable housed within a cable sheath.

[0020] Cable sealing elements can seal cable sheaths, preferably preventing contaminants, liquids, and / or moisture. They can also provide gas impermeability. In particular, for this purpose, cable sealing elements can provide a seal between the cable sheath and the inner surface of the housing component forming the cable sheath.

[0021] The cable sealing element is preferably formed as a single piece.

[0022] Specifically, a cable sealing element can be provided that is completely closed or annular in the circumferential direction and has a central opening for guiding the cable through. The cable sealing element is preferably secured within the cable sheath, for example, by form-fit, pressure fit, or by material bonding. For example, the cable sealing element can also be injection molded into a first housing component, another housing component, and / or the housing fastening component described below.

[0023] The cable sealing element may extend along the entire cable sleeve, or it may be arranged only in a portion of the cable sleeve. Alternatively, a plurality of cable sealing elements may be provided continuously distributed along the cable feed direction.

[0024] It should be mentioned in this regard that the invention is also applicable to use with housing assemblies or plug connectors to which several cables are supplied. For this purpose, cable sleeves can be configured accordingly, wherein several cable sleeves can also be provided that lead into the interior of the housing assembly (e.g., arranged adjacent to or parallel to each other, but starting from different directions or sides of the housing assembly).

[0025] The cable sheath can be configured, for example, to precisely accommodate one cable, two cables, three cables, four cables, five cables, or two or more cables. Each cable can be assigned to a separate cable sealing element (a plurality of cable sealing elements may be provided correspondingly within the cable sheath), however, several cables (e.g., two, three, or all of them in their respective cases) can also be guided through a joint cable sealing element, wherein the joint cable sealing element preferably has a plurality of adjacent openings for the respective guiding passage of individual cables.

[0026] The invention is described below primarily based on a housing assembly or plug connector having only a single cable. However, this should only be used for purposes of improving understanding and should not be construed as limiting the invention.

[0027] According to the invention, the housing assembly has a housing fastening member that at least partially surrounds the housing assembly (at least the first housing assembly and the second housing assembly) in the region of the cable sheath.

[0028] Preferably, the housing fastening member is formed as a terminal cap or end cap for the housing assembly. The housing fastening member can preferably surround the housing assembly at least from the cable-side end of the cable sheath. It can also be provided that the housing fastening member is formed as annular or sheath-shaped and does not have a face-side terminal surface or stop surface.

[0029] Specifically, the housing fastening components surround the first housing component (and / or the second housing component, also referred to below), at least in the area of ​​the cable sheath (where the cable sealing element is arranged).

[0030] The housing fastening components advantageously increase the stiffness of the housing assembly in the cable sheath area. Mechanical loads on the cable can be at least substantially absorbed by the housing fastening components, preventing the cable sealing element from separating from the inner surface of the housing component forming the cable sheath. It has been unexpectedly shown that the impermeability of the housing assembly can be significantly improved by using the housing fastening components.

[0031] According to the present invention, at least a first housing component and a housing fastening component are connected to each other as a single unit in a pre-assembled state via at least one connecting web.

[0032] The connecting web preferably has only a very small thickness or less than the thinnest wall thickness of the shell components and / or shell fastening components, for example, 1.5 times, 2 times, or even less.

[0033] Manufacturing at least one of the housing fasteners and housing components in a single piece can reduce the cost of producing housing assemblies, especially if production is performed as a joint plastic injection molded component.

[0034] In an advantageous further improvement of the invention, it can be provided that the connecting web is formed as a predetermined break point so as to separate the first housing component from the housing fastening component before or during final assembly.

[0035] Due to the disconnection or predetermined disconnection point of at least one connecting web, individual components of the housing assembly can subsequently be treated as separate parts in a conventional manner during the final assembly process.

[0036] At least one connecting web can be specifically configured to break due to axial movement of the housing fastening components in the direction of the cable sheath.

[0037] According to a further improvement of the invention, the connecting web is provided to be at least partially elastically deformable, particularly in the manner of a membrane hinge, so as to enable the housing fastening component to be assembled onto the first housing component.

[0038] It can be provided that, despite the connecting web, defined relative movement (e.g., rotational or pivotal movement) between the shell fastening member and at least one shell member is possible.

[0039] In an advantageous further improvement of the invention, it can be provided that the housing fastening member is arranged in a pre-assembled state to rotate and / or pivot relative to its state assembled on the first housing member.

[0040] The housing fastening component can also be connected to the housing component via at least one connecting web, such that in the unassembled or pre-assembled state, the housing fastening component is spaced apart from the cable input end along the fastening assembly direction (e.g., along the cable feed direction) compared to the state when assembled on the housing component.

[0041] In a further improvement of the invention, at least one connecting web may be formed in the region of the cable sheath of the first housing component.

[0042] Precisely, a single connecting web can be provided. However, several connecting webs can also be provided. Where several connecting webs are provided, these connecting webs can preferably be arranged along the circumference of the cable sheath, for example, in equidistant angular segments. However, these connecting webs can also be arranged parallel to or close to each other, particularly in the mating plane, for example, to allow for bending or pivoting movement.

[0043] According to a further improvement of the invention, the housing assembly may have a second housing component that can be mechanically connected to the first housing component.

[0044] The housing components preferably form corresponding circumferential portions of the cable sheath when they are connected together, wherein the housing fastening components at least partially surround the first housing component and the second housing component in at least the region of the cable sheath in order to secure the housing components to each other.

[0045] Experience has shown that undesirable separation of the cable sealing element from the inner wall of the plug connector housing under lateral forces acting on the cable is particularly significant in the case of multi-part plug connector housings. In such cases, the cable sealing element is often arranged between two housing components that have a degree of mobility relative to each other due to the virtually always present clearance. Therefore, the present invention is particularly advantageous (but not exclusively) applicable to housing assemblies in which the cable sheath is formed by several housing components. Consequently, the housing fastening component is preferably capable of engagingly surrounding the first and second housing components to secure the housing components to each other.

[0046] The housing fastening components can advantageously connect housing components to each other with the smallest possible clearance, so as to reduce movement between housing components and increase the rigidity of the housing assembly—particularly in the area of ​​the cable sheath and particularly preferably in the portion of the cable sheath where the cable sealing element is arranged.

[0047] In addition to the first and second housing components, further housing components, such as a third, fourth, and even more housing components, may be provided within the context of the present invention or the proposed housing assembly. For the purposes of the term "housing component" discussed below, this designation should be considered to refer at least to the first and second housing components; however, it may also refer to other housing components, even if not explicitly indicated.

[0048] In cases where multi-part plug connector housings or housing assemblies are regularly used for angled plug connectors, a first housing component and a second housing component can thus relate to the housing components of the angled plug connector. At least one housing component can then be angled to correspond to the terrain; however, this is not absolutely necessary.

[0049] The second housing component can, for example, form the housing base of the plug connector, and the first housing component can form a housing cover of the housing base. Generally, the housing components can preferably form an inner plug connector housing. Then, the housing fastening components mentioned below can be mounted on the inner plug connector housing (and thus can also be referred to as an "outer plug connector housing" or "terminal cover").

[0050] Preferably, a first portion of the circumferential portion of the cable sheath is formed by a first housing component, and a second portion of the circumferential portion of the cable sheath is formed by a second housing component. The housing components forming the cable sheath together may optionally overlap at least partially along the circumference of the cable sheath, although each housing component is preferably assigned at least substantially to its own circumferential portion of the cable sheath. The cable sheath is preferably at least substantially completely closed in the circumferential direction (e.g., except for any gaps in the transitions between the housing components).

[0051] According to a further improvement of the invention, the housing assembly direction for connecting the first housing component to the second housing component is different from the fastening assembly direction for assembling the housing fastening component onto the housing component.

[0052] Specifically, the housing assembly direction and the fastening assembly direction may extend at an angle between 45° and 90° to each other, preferably orthogonal or at least substantially orthogonal. In this way, assembly can be performed particularly easily and gently, wherein the housing fastening components can simultaneously prevent unintentional disassembly of the housing components.

[0053] However, it is also possible to provide that the housing assembly direction and the fastening assembly direction extend parallel to each other or at least substantially parallel (e.g., at an angle of less than 45°). In this case, for example, assembly can be performed by temporarily deploying the clamp-like housing fastening components. Also in this case, the housing fastening components can prevent unintentional disassembly of the housing components.

[0054] In an advantageous further improvement of the invention, it can be provided that the housing fastening member on at least one of the housing components is displaceable (particularly along the feed direction for the cable, or at least substantially along the feed direction for the cable, however, it may also be along a direction deviating from that direction).

[0055] The housing fastening component can preferably be guided on at least one housing component, particularly until the housing fastening component reaches its final assembly position where it secures the housing component. For example, it can be specified that the housing fastening component and at least one housing component form a mutual linear guide.

[0056] Assembly of housing components can be simplified by a guiding function and can reduce sensitivity to errors (especially the risk of damaged parts).

[0057] For example, the housing fastening component may be linearly guided on the outer surface of at least one housing component, as the housing fastening component completely or partially surrounds or fastens at least one housing component forming the cable sheath.

[0058] Alternatively or additionally, for example, a track guiding system may be provided, wherein the housing fastening member has one or more protrusions (e.g., webs, pins, sliders, etc.), the one or more protrusions being linearly guided in one or more corresponding recesses (e.g., grooves or folds), the one or more corresponding recesses being arranged along the assembly direction of the housing fastening member (hereinafter referred to as the "fastening assembly direction"). A reverse arrangement (and hybrid variations) may also be provided, in which the housing fastening member has a recess and the housing member has protrusions.

[0059] According to a further improvement of the invention, it can be provided that the housing fastening member surrounds at least the first housing component in the region of the cable sheath in a circumferential, particularly annular, manner.

[0060] In the case of a circumferentially closed housing fastening component, the cable sheath can be mechanically strengthened or reinforced particularly effectively. Therefore, variations of the invention may be particularly suitable if very high lateral forces are expected on the cable.

[0061] However, in a further improvement of the invention, it may also be provided that the housing fastening component is fastened only around at least the first housing component in the area of ​​the cable sheath.

[0062] Specifically, it can be provided that, for this purpose, the housing fastening member has at least one support surface and two side legs, the housing fastening member being supported by the at least one support surface on a reverse support surface (i.e., on at least one outer surface of the housing member) of at least one housing member forming a cable sheath, the two side legs extending from the support surface along corresponding opposite sides of the at least one housing member. Preferably, at least one of the side legs (particularly preferably both side legs) fastens at least one housing member on the side opposite to the reverse support surface.

[0063] Alternatively or additionally, at least one (particularly preferably two) of the side legs may have a raised portion (e.g., a web or pin) located in one or more portions between the reverse support surface and the housing side opposite the reverse support surface. This allows for fixation or clamping within the side surface of the housing component.

[0064] Advantageously, at least one housing component, secured by housing fastening members, can also be used as a linear guide, such as a track guide system.

[0065] In one configuration of the invention, the housing fastening member can be securely connected to at least one of the housing components (preferably at least to the first and second housing components) in its assembled state.

[0066] Specifically, the housing fastening component can be locked, pressed, or threaded onto a first housing component and / or a second housing component. Locking is particularly preferred because it can be implemented using technically simple devices and allows for easy assembly and disassembly. Therefore, the housing fastening component can have one or more locking elements, and the housing component can have a corresponding reverse locking element. The locking element or reverse locking element can be, for example, a resilient or elastic locking arm, a locking spring, a locking extension (e.g., a locking hook), an edge, or a locking receiver (e.g., an opening or recess).

[0067] Preferably, in each case, at least one locking element is arranged on at least two sides of the housing fastening member, specifically on opposite sides or sides away from each other.

[0068] As already mentioned, a threaded connection between the housing fastening component and one of the housing components can also be provided, if necessary. This is particularly advantageous if at least the corresponding housing component is formed to be at least substantially rotationally symmetrical.

[0069] It can be provided that the first housing component and the second housing component are fastened to each other in their interconnected state by means of pressure fit, form fit and / or material locking.

[0070] In a particularly preferred configuration of the invention, the first housing component and the second housing component can be locked together.

[0071] Locking is particularly preferred because it can be implemented using technically simple devices and is easy to assemble and disassemble. Therefore, the first housing component may have one or more locking elements, and the second housing component may have a corresponding reverse locking element. The locking element or reverse locking element may be, for example, a resilient or elastic locking arm, a locking spring, a locking extension (e.g., a locking hook), an edge, or a locking receiver (e.g., an opening or recess).

[0072] In an advantageous configuration of the invention, the housing fastening component may be made of the same material as at least one of the housing components.

[0073] Preferably, all housing components of the housing assembly, particularly the first and second housing components and the housing fastening components, are formed of the same material.

[0074] The housing components (particularly the first and second housing components) and / or housing fastening components are preferably formed of plastic (particularly hard plastics, such as thermoplastics or thermosetting plastics (preferably not elastomers)). However, components may also be formed of metal, ceramics, or other materials. Combinations of multiple materials may also be provided (within the same component or within the housing assembly). The housing assembly is particularly preferably formed as an electrically insulating connector housing. However, the housing assembly may also, for example, form the outer conductor assembly of a plug connector.

[0075] In an advantageous configuration of the invention, the housing components together, in their connected state, form a housing assembly for an angled plug connector.

[0076] Specifically, at least one of the housing components can be formed at an angle.

[0077] In a further improvement of the invention, the housing assembly may be provided with a housing sealing element configured to ensure a seal between the first housing component and at least one other housing component, particularly a second housing component.

[0078] The housing sealing element is preferably formed as a single piece.

[0079] What can be provided is that the housing sealing element has a circumferentially closed or annular profile and forms a central opening.

[0080] Specifically—but not exclusively—in the case of a housing assembly for an angled plug connector, it may be provided that the housing sealing element is formed in an angled manner such that a first portion of the housing sealing element and a central opening extend in a first plane, and a second portion of the housing sealing element and a central opening extend in a second plane.

[0081] The first and second planes are preferably arranged at an angle between 45° and 90° to each other, and in particular, are aligned orthogonally or at least substantially orthogonally to each other. However, in principle, any angle can be provided between the first and second planes.

[0082] The first part of the housing sealing element preferably corresponds to the U-shaped portion or the partially annular portion of the housing sealing element. The second part of the housing sealing element preferably corresponds to another U-shaped portion or annular portion of the housing sealing element.

[0083] The transition region can preferably be located between the first and second parts of the housing sealing element, particularly a transition region with a curved profile, so as to enable a material-friendly transition between the different orientations of these parts.

[0084] The first part is preferably longer than the second part, wherein the second part of the housing sealing element is preferably arranged in the area of ​​the cable sheath.

[0085] In an advantageous configuration of the invention, the housing sealing element may be provided in a material-bonded manner connected to one of the housing components.

[0086] The housing sealing element can be glued to one of the housing components, or in particular, injection molded into one of the housing components. In this way, the delivery status can be captured.

[0087] However, it is also possible to provide a housing sealing element that is connected to at least one of the housing components in a pressure-fit or form-fit manner. In principle, a capture connection to one of the housing components is not absolutely necessary when the housing assembly is disassembled—therefore, it is sufficient if the housing sealing element is only secured by the final assembly for the purpose of sealing between the housing components.

[0088] The housing sealing element and / or cable sealing element may have one or more (e.g., two, three, four or even more) sealing lips.

[0089] In one configuration of the invention, the cable sealing element and the housing sealing element may be provided as a single unit formed by a common sealing body.

[0090] Specifically, it can be provided that the cable sealing element and the housing sealing element form corresponding parts of a common seal. The production of the common seal can reduce manufacturing costs and also make assembly easier and more reliable.

[0091] The present invention also relates to a plug connector, particularly an electrical plug connector having a housing assembly according to the above and below embodiments and at least one contact element that can be connected to a cable (e.g., an inner conductor contact element or an outer conductor contact element).

[0092] The mechanical properties of the housing assembly can be enhanced by using a housing fastening member that can serve as the outer shell of at least a first housing component, at least in the area of ​​the cable sleeve of the plug connector. Specifically, the rigidity and lateral tensile strength in the area of ​​the cable sleeve can be increased because the wall thickness of the first housing component is increased and the first housing component can be secured to a second housing component (if present). In the proposed manner, particularly robust and waterproof plug connectors can be provided, especially waterproof angled plug connectors.

[0093] The plug connector according to the invention can, in principle, have any desired plug connector components. For example, the plug connector can have various contact elements, mechanical insertion interfaces for connection to mating plug connectors, dielectrics, shielding devices, and other sealing elements.

[0094] As already mentioned, the plug connector can be an electrical plug connector (e.g., a shielded electrical plug connector, a coaxial plug connector, or a differential plug connector), an optical plug connector, or other plug connectors. This invention should not be construed as being limited to specific variations.

[0095] The connector according to the invention can be particularly advantageously used in vehicles, especially motor vehicles. Applications include autonomous driving, driver assistance systems, navigation systems, infotainment systems, rear-seat entertainment systems, internet connectivity, and gigabit wireless (IEEE 802.11ad standard). Possible applications include high-resolution cameras (such as 4K and 8K cameras), sensors, in-vehicle computers, high-resolution screens, high-resolution dashboards, 3D navigation devices, and mobile devices. It can also be used as a high-voltage connector. However, the plug connector according to the invention is applicable to any application throughout the entire field of electrical engineering and is not limited to use in vehicle technology.

[0096] The present invention also relates to a method for assembling a plug connector, the method comprising at least the following steps:

[0097] A housing assembly is provided, the housing assembly having at least one first housing component and a housing fastening component, the housing fastening components being connected to each other as a single unit in a pre-assembled state via at least one connecting web;

[0098] The cable is introduced through a cable sealing element housed in a cable sleeve formed of at least a first housing component; and

[0099] The housing fastening components are finally assembled onto at least the first housing member, such that at least the first housing member is at least partially surrounded by the housing fastening components within the area of ​​the cable sheath.

[0100] In this process, at least one connecting web is disconnected during or before final assembly in order to separate the first housing component from the housing fastening component.

[0101] It should be emphasized that the method steps mentioned do not necessarily have to be in the order in which they are first described or mentioned. For example, individual method steps or groups of method steps can be interchanged if this is not technically possible. Method steps can also be combined with each other, divided into individual intermediate steps or supplemented with intermediate steps. The method does not necessarily have to be described last among the described method steps, and may be supplemented with other method steps not mentioned.

[0102] Preferably, the cable sealing element and / or housing fastening component have been pushed onto the cable before the cable is inserted into the cable sleeve.

[0103] Features already described in conjunction with one of the subjects of the invention (i.e., given by the housing assembly according to the invention, the plug connector according to the invention, and the method according to the invention) can also advantageously realize other subjects of the invention. Similarly, the advantages mentioned with respect to one of the subjects of the invention can also be understood in relation to other subjects of the invention.

[0104] Furthermore, it should be noted that terms such as “comprising,” “having,” or “with” do not exclude any other features or steps. Additionally, terms such as “a” or “the” that refer to a singular number of steps or features do not exclude multiple features or steps, and vice versa.

[0105] However, in pure embodiments of the invention, it may also be provided that the features introduced in the invention by the terms "comprising," "having," or "with" are listed exhaustively. Thus, a list of one or more features may be considered exhaustive within the scope of the invention, for example, and may be considered for each claim. The invention may, for example, consist exclusively of the features mentioned in claim 1.

[0106] It should be mentioned that terms such as “first” or “second” are used primarily to distinguish the features of the respective apparatus or method, and are not necessarily intended to indicate that the features are interdependent or related to each other.

[0107] Furthermore, it should 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 very particularly preferably ±0.1% or less, of the respective specified values ​​or parameters, provided that such deviations are not excluded when the invention is practiced in practice. The description using ranges of starting and ending values ​​also covers all those values ​​and fractions included within their respective known ranges, particularly the starting and ending values ​​and their corresponding averages.

[0108] The present invention also relates to a housing sealing element for a housing assembly for a plug connector, independent of claim 1, wherein the applicant reserves the right to separately claim protection for this separate housing sealing element, as defined below. The separate housing sealing element has a circumferentially closed profile and forms a central opening. The separate housing sealing element is characterized in that it is formed at an angle such that a first portion of the housing sealing element and the central opening extend in a first plane, and a second portion of the housing sealing element and the central opening extend in a second plane. The features mentioned above and below, particularly those relating to the housing sealing element of the housing assembly according to claim 1, and especially the features of claim 13, relate to advantageous embodiments and variations of the separate housing sealing element. In particular, the applicant also reserves the right to separately claim protection for housing components of the housing assembly having the aforementioned separate housing sealing element (particularly if the housing sealing element is injection molded in the housing component), wherein the features of the first housing component and / or the second housing component described above and below should be understood as advantageous embodiments and variations of the separate housing component. Finally, the applicant also retains the right to separately claim protection for the plug connector having a housing assembly having the aforementioned housing component with a separate housing sealing element.

[0129] Figure 17 Shown in 3D Figure 15 The plug connector is in the assembled state. Detailed Implementation

[0130] exist Figures 1 to 5 The invention illustrates, by way of example, several assembly steps of the housing assembly 2, showing a plug connector 1 (e.g., an electrical plug connector) having the housing assembly 2 and a cable 3 (e.g., a power cable) leading into the housing assembly 2. Exemplary embodiments show angled plug connectors; however, this should not be construed as limiting the invention. In principle, the invention is also applicable to non-angled plug connectors.

[0131] exist Figures 1 to 5 The plug connector 1 shown by way of example can have a variety of known plug connector components. By way of example, the contact element 4 (e.g., an outer conductor contact element or an inner conductor contact element) is indicated in the figure.

[0132] The housing assembly 2 has at least a first housing component 5. In principle, this is sufficient within the scope of the invention, and will be used below. Figures 15 to 17 This will be illustrated by exemplary embodiments. However, in Figures 1 to 14 In an exemplary embodiment, the housing assembly 2 further includes a second housing component 6. The first housing component 5 and the second housing component 6 can be mechanically connected to each other, such as... Figure 1 and Figure 2 As shown. In Figures 3 to 5 In this configuration, housing components 5 and 6 are connected to each other, and together they form a cable sleeve 7. The cable 3 can be introduced through the cable sleeve 7 into the interior 8 of the housing assembly 2 or the interior 8 of the plug connector 1 (see [link]). Figure 1 For this purpose, housing components 5 and 6 form corresponding circumferential portions U1 and U2 of cable sheath 7 (see...). Figure 1 and Figure 8 ).

[0133] The two housing components 5 and 6 can be locked together. For this purpose, the first housing component 5 has at least one at least partially spring-resilient locking arm 9, which has a locking receiver 10 that can be held at the rear by a corresponding locking hook 11 of the second housing component 6 (see, for example, [link to relevant documentation]). Figure 3 (Assembled state). However, in principle, the connection between the first housing component 5 and the second housing component 6 can also be secured in another way (e.g., by threaded connection, friction connection, or even by material connection).

[0134] Cable sealing element 12 for cable 3 (see Figures 6 to 10 The cable sheath 13 is housed within a cable sleeve 7 formed by two housing components 5 and 6, so as to form a seal between the cable sheath 13 and the inner surface 14 of the housing components 5 and 6 forming the cable sleeve 7 (see [link]). Figure 1 ).

[0135] In an exemplary embodiment, for example, the cable sealing element 12 and the housing sealing element 15 are formed as a single piece by a common sealing body 16. In variations, which should be understood as illustrative only, Figure 6 and Figure 7 The common seal is shown in the individual representations. In principle, multi-part configurations and therefore individual cable sealing elements 12 are also possible.

[0136] The cable sealing element 12 is primarily formed in a tubular or sleeve shape, wherein, when the housing assembly 2 is fully assembled, the outer surface 17 of the cable sealing element 12 preferably extends across the entire surface of the inner surface 14 of the housing components 5 and 6 in the region of the cable sleeve 7. The cable sealing element 12 is formed to be completely closed or annular in the circumferential direction and has a central opening 18 for the cable 3 to pass through (see...). Figure 6 ).

[0137] The aforementioned housing sealing element 15 is formed to ensure a seal between housing components 5 and 6 and also forms a circumferentially closed profile with another central opening 19 (see [link]). Figure 6 Similar to housing components 5 and 6, the housing sealing element 15 is formed at an angle such that the first portion 20 (“U-shaped” portion) of the housing sealing element 15 or the first portion 20 of the central opening 19 extends in the first plane E1, and the second portion 21 (“U-shaped” portion) of the housing sealing element 15 or the second portion 21 of the central opening 19 extends in the second plane E2, as shown. Figure 7 As shown. Planes E1 and E2 are preferably arranged orthogonally to each other, such as, for example, in... Figure 2 and Figure 7 As can be clearly seen from the background. The transition section 22 can be set between the two sections 20 and 21 to achieve a uniform and smooth (e.g., circular) transition between the two sections 20 and 21.

[0138] The sealing body 16 or housing sealing element 15 and / or cable sealing element 12 can be fixed in at least one of the housing components 5 and 6, specifically connected to one of the housing components 5 and 6 by means of material bonding. For example, during the manufacturing process, the sealing body 16 or housing sealing element 15 can be injection molded into the first housing component 5. In this way, manufacturing costs can be reduced and the assembly process can be simplified.

[0139] The proposed housing assembly 2 further includes a housing fastening member 23, which at least partially closes the housing components 5 and 6 in the region of the cable sheath 7 and particularly in the region of the cable sealing element 12, so as to secure the housing components 5 and 6 to each other.

[0140] Housing fastening component 23 can be displaced to the final assembly position at least on one of housing components 5 and 6 (see [reference]). Figure 4 and Figure 5 This displacement preferably occurs along the feed direction Z of the cable (see...). Figure 1 and Figure 3 However, if necessary, the feed direction Z of cable 3 can be deviated. In the final assembled position, housing fastener 23 secures housing components 5 and 6 together, and thus increases the mechanical stability of housing assembly 2 against lateral loads in the area of ​​cable sleeve 7, thereby maintaining impermeability even under adverse operating conditions.

[0141] Housing assembly direction G (see Figure 2 ) and fastening assembly direction S (see Figure 3 Preferably, the housing assembly direction G is different from the housing assembly direction S, which is used to connect the first housing component 5 to the second housing component 6, and the fastening assembly direction S is used to assemble the housing fastening component 23 onto the housing components 5 and 6. Particularly preferably, the housing assembly direction G and the fastening assembly direction S extend orthogonally to each other. However, this is not absolutely necessary—the fastening assembly direction S can also extend in the same direction as the housing assembly direction G—especially if the housing fastening component 23 is not completely closed in the circumferential direction.

[0142] To facilitate the displacement of the housing fastening member 23 on at least one housing member 5, 6, guides, particularly linear guides, can be provided, especially in the regions of the housing members 5, 6, where the cable sheath 7 is formed. Specifically, the guiding function and the securing function of the housing fastening member 23 for assembly can be complementary.

[0143] Figures 8 to 10 The front view of the cable sleeve 7 in its assembled state shows three exemplary variations of the housing fastening component 23.

[0144] For example, if the housing fastening component 23 completely encloses the housing components 5 and 6 in the area of ​​the cable sleeve 7, such as Figure 8 As shown, exceptionally robust stability can be achieved for the cable sleeve 7. A linear guide can also be provided due to the corresponding interaction between the inner surface of the housing fastening member 23 and the outer surfaces of the housing members 5 and 6 (particularly in the region of the cable sleeve 7).

[0145] Circumstances and basis Figure 9 Similar to the housing fastening member 23, the housing fastening member 23 only fastens the housing members 5 and 6 in the region of the cable sleeve 7. For this purpose, the support surface 24 of the housing fastening member 23 rests on the reverse support surface 25 of the housing members 5 and 6 that form the cable sleeve 7. Starting from the support surface 24 of the housing fastening member 23, two opposing side legs 26 extend, which fasten the second housing member 6 at their ends. Consequently, a linear guide can be formed simultaneously.

[0146] Figure 10 Another type of fastening with integrated linear guides is shown. A track guide system 27 is formed on both sides. Correspondingly, the side legs 26 have elongated webs 28 that extend in the fastening assembly direction S and are guided in corresponding grooves 29 in the housing components 5, 6.

[0147] In its assembled state, the housing fastening member 23 can be securely attached to at least one of the housing members 5 and 6. In an exemplary embodiment, the housing fastening member 23 can be locked to the first housing member 5 and the second housing member 6. For this purpose, the housing fastening member 23 has a locking arm 30 that is at least partially resilient, the locking arm 30 having a locking receiver 31 (see...). Figure 1 It can be held at the rear by the locking hooks 32 of the corresponding housing parts 5 and 6 (see [reference]). Figure 1 and Figure 2 In principle, the fastening between housing fastening member 23 and at least one of housing members 5 and 6 can occur in any desired manner (e.g., also by pressing or threaded connection (not shown)).

[0148] In the context of the method for assembling the electrical connector 1, for example, a cable 3 may first be provided passing through a housing fastening member 23 and a cable sealing element 12 (equivalent to pre-assembling the housing fastening member 23 and the cable sealing element 12 onto the cable 3). The housing fastening member 23 may then be assembled such that at least a first housing member 5 is at least partially surrounded in the area of ​​at least the cable sleeve 7. Provided are two (or more) housing members 5, 6, which may optionally be connected or assembled to each other before the housing fastening member 23 is assembled, such that the housing members 5, 6 form corresponding circumferential portions U1, U2 of a common cable sleeve 7 through which the cable 3 is guided into the interior 8 of the plug connector 1.

[0149] To further improve the production and assembly of the housing assembly 2, it may be optionally provided that at least one of the housing components 5 and 6 (in these exemplary embodiments, the first housing component 5 in each case) and the housing fastening component 23 are integrally connected to each other via at least one connecting web 33 in a pre-assembled state or an unassembled state. This should first be based on... Figures 11 to 14 The exemplary embodiments are explained in more detail to illustrate the principles.

[0150] Figures 11 to 14 A substantially similar exemplary embodiment of the invention has been shown, as has been previously described. Figures 1 to 10 This explanation is based on the above, which is why components with the same function are no longer described in detail. Cable 3 and cable sealing element 12 or sealing body 16 are... Figures 11 to 14 The housing assembly 2 is hidden. Again, the housing assembly 2 has a first housing component 5 and a second housing component 6, which together form a cable sleeve 7 in the assembled state, and the cable sealing element 12 for the cable 3 is housed in the cable sleeve 7.

[0151] For the integral connection between the first housing component 5 and the housing fastening component 23, a connecting web 33 is provided, which is formed in the manner of a membrane hinge. For this purpose, the connecting web 33 has at least partially a very thin wall thickness and is therefore sufficiently elastic to allow pivoting movement between the housing fastening component 32 and the first housing component 5. The end position of the housing fastening component 32 on the first housing component 5 may have already been achieved through this pivoting movement. However, if necessary, it can also be provided that the connecting web 33 disengages in a defined manner during the pivoting movement and / or during subsequent axial movement. Therefore, the connecting web 33 can also be formed with a predetermined disconnection point.

[0152] Through the connecting web 33, the first housing component 5 and the housing fastening component 23 can be manufactured together during assembly, particularly through a common plastic injection molding process. The first housing component 5 and the housing fastening component 23 can be separated by disconnecting a predetermined disconnection point before or during final assembly, or can be assembled together by guided movement on the connecting web 33. The housing fastening component 23 and the housing components 5 and 6 are therefore preferably formed of the same material (especially plastic).

[0153] After assembling these two housing components 5 and 6 (see...) Figure 11 and Figure 12 Therefore, it can be provided that, for example, the housing fastening member 23 is first pivoted (see...). Figure 12 and Figure 13 ), housing fastening component 23 in Figure 11 and Figure 14In an exemplary embodiment, the housing fastener 23 is held in a pre-assembled state by the connecting web 33, rotated or pivoted, and axially (along the feed direction Z of the cable 3) relative to the final assembly position. The housing fastener 23 then shifts along the fastening assembly direction S to the final assembly position (see [link to example]. Figure 13 and Figure 14 The connecting web 33 can optionally be configured to disconnect at any time during the assembly process, particularly along the fastening assembly direction S (in Figure 13 Disconnected during axial displacement (as indicated in the middle).

[0154] exist Figures 11 to 13 In an exemplary embodiment, exactly one connecting web 33 is provided for connecting the housing fastening member 23 to the first housing member 5. However, in principle, several connecting webs 33 may also be provided, for example, several connecting webs 33 distributed circumferentially along the circumference of the cable sleeve 7, and for example, distributed at equal intervals, such as in Figures 1 to 5 In China and especially Figures 8 to 10 As shown in the diagram. When using a plurality of connecting webs 33 distributed circumferentially along the cable sleeve 7, it is preferably provided that, compared with the final assembled state, the housing fastening members 23 are offset only axially along the feed direction Z or the fastening assembly direction S, without twisting or pivoting.

[0155] As already mentioned, within the scope of this invention, the connecting web 33 does not absolutely need to be disconnected during assembly. In principle, the connecting web 33 can also be configured to be sufficiently elastic or deformable so that the housing fastener 23 can be moved to the final assembled position without disconnecting. However, this is less preferred.

[0156] As already mentioned, it is advantageous, but not absolutely necessary, within the scope of this invention, for the housing assembly 2 to have multiple housing parts 5, 6. In principle, the first housing part 5 may already be sufficient, and the outer wall of the first housing part 5 can then be mechanically reinforced by means of the housing fastening member 23. Figures 15 to 17 The corresponding exemplary embodiment is shown by way of example, wherein the plug connector 1 or housing assembly 2 has only a single housing component 5. The cable 3 and cable sealing element 12 or seal 16 are also present. Figures 15 to 17 The text is hidden to simplify the illustration.

[0157] Figures 15 to 17 Cutouts of the coaxial plug connector 1 are shown, wherein the specific geometry and plug type are not important within the scope of the invention. The exemplary circular plug connector 1 has a first housing component 5, and the housing fastening component 23 can be linearly displaced along the outer sheath of the first housing component 5 in the feed direction Z (not shown) of the cable 3.

[0158] For example, based on Figure 16 As can be seen in the enlarged cut, the first housing component 5 and the housing fastening component 23 are... Figure 15 and Figure 16 In the pre-assembled state shown, the components are connected to each other as a single piece via several connecting webs 33 arranged circumferentially (however, a single connecting web 33 may be sufficient, as described above). These connecting webs 33 are formed at predetermined break points and are disconnected in a defined manner due to the axial displacement of the housing fasteners 23 in the direction of the final assembly position. Figure 16 In the final assembly position shown, the first housing component 5 is locked together with the housing fastening component 23 (see the locking arm 30 or locking receiver 31 of the housing fastening component 23 and the locking hook 32 of the first housing component 5).
