Description

Technical Field

[0001] This invention relates to a multi-core cable crimping ferrule for an electrical connection device for multi-core cables, particularly an HF multi-core cable crimping ferrule. The invention also relates to a method for assembling a multi-core cable crimping ferrule, particularly an HF multi-core cable crimping ferrule, by crimping it onto a stripped, non-circular internal cross-section of the multi-core cable. Furthermore, the invention relates to an electrical connection device, particularly an HF connection device, and an electrical entity, particularly an HF entity. Background Technology

[0002] In the electrical field (electronics, electrical engineering, circuits, power technology, etc.), a large number of electrical connector devices or connector assemblies, sockets, pins, and / or hybrid connectors, hereinafter referred to as (electrical) connectors (also known as mating connectors), are known for transmitting current, voltage, signals, and / or data at wide bandwidths of current, voltage, frequency, and / or data rates. In low, medium, or high voltage and / or current applications, particularly in the automotive field, such connectors must ensure the permanent, repeatable, and / or short-term transmission of power, signals, and / or data after relatively long periods of inactivity in environments subjected to mechanical stress, warmth, potential heat, contamination, humidity, and / or chemical corrosion. Due to their wide range of applications, numerous specially designed connectors are known.

[0003] Such connectors, and if applicable, their associated (e.g., in the case of connector devices or connector assemblies) or higher-level housings (e.g., in the case of connector assemblies), can be mounted to wires, cables, cable bundles, etc. (hereinafter referred to as assembled (electrical) cables (also known as: electrical entities)) or mounted to / on electrical devices or apparatuses, such as mounted to / on (electrical) electrical, electro-optical or electronic components or corresponding assemblies, etc., mounted to / on lead frames, mounted to / on circuit boards, etc.

[0004] If a connector (with or without a housing) is located on a cable, line, or cable bundle, it is also called a floating (plug) connector or plug, socket, or coupling; if it is located on or within an electrical, optoelectronic, or electronic component, assembly, etc., it is also called a connector assembly, such as a (built-in / mounted) connector, (built-in / mounted) plug, or (built-in / mounted) socket. Connectors on such assemblies are also frequently referred to as (plug) receptacles, pin connectors, pin straps, or connectors. - In the context of electrical engineering (generating, converting, storing, and transmitting high-voltage current in the power grid, preferably three-phase high-voltage transmission), this refers to cable assemblies because of their relatively complex structure.

[0005] Such connectors must ensure the proper transmission of electricity, wherein corresponding and partially complementary connectors (connector and mating connector) typically have locking and / or fastening devices for permanently but generally releasably locking and / or fastening the connector to / into the mating connector, and vice versa. Furthermore, the electrical connection means for the connector, for example including or having at least: actual electrical contact devices (terminals; typically substantially formed as a single piece or integral, such as (crimp) contact elements, etc.) or electrical contact devices (terminals; typically configured as a single piece of several or two parts, or substantially integral, such as (crimp) contact devices), must be securely held therein.

[0006] The connecting device itself can be formed from several parts. Here, the connecting device may include or have, for example, two or more electrical terminals. This is the case, for example, with coaxial, biaxial, or twisted-pair connecting devices, which may include or have one or two internal electrical terminals (male and / or female terminals) and an external terminal (shielded contact sleeve). Furthermore, a ferrule (support sleeve) may be built into the external terminal of the connecting device. In the case of (pre-)assembled cables, such a connecting device can be provided as a connector (see above), that is, without a housing, for example, in a suspended manner.

[0007] Efforts have been made to improve electrical connectors and their connection devices, particularly through miniaturization, to make them more robust, to design them more efficiently, and to manufacture them at a lower cost. Here, the rules apply to HF connection devices (HF: High Frequency, defined here as transmission frequencies greater than 3MHz to greater than 300MHz, and fully into the GHz range (approximately 150GHz)). This differs significantly from the rules for conventional connection devices (defined here as transmission frequencies below approximately 3MHz) because the fluctuating characteristics of electricity are particularly pronounced in HF technology. Maintaining signal integrity proves to be a greater obstacle in the case of HF plug electrical connections.

[0008] There is a visible trend among cable manufacturers to make the shielding in multi-core cables (such as twisted-pair cables, biaxial cables, etc.) more oval-shaped, as more and more manufacturers are placing the shielding directly around the inner conductors of multi-core cables, rather than around additional filler as before. However, the insulation sheath of multi-core cables remains substantially circular. Conventional crimping rings for crimping connections of such multi-core cables are designed so that they are only suitable for crimping onto substantially circular shielding. Therefore, the object of this invention is to specify an improved connection device. Summary of the Invention

[0009] The object of the present invention is achieved by a multi-core cable crimping ferrule, particularly an HF multi-core cable crimping ferrule, for an electrical connection device for multi-core cables; by a method for assembling the multi-core cable crimping ferrule, particularly an HF multi-core cable crimping ferrule, onto the stripped non-circular inner cross-section of the multi-core cable; by an electrical connection device, particularly an HF connection device; and by an electrical entity, particularly an HF entity. - Advantageous developments, additional features, and / or advantages of the invention are derived from the dependent claims and the following description.

[0010] The multi-core cable crimping ferrule according to the invention comprises a preferred axial assembly portion for assembling the crimping ferrule on a substantially non-circular inner cross-section of the multi-core cable, and a preferred axial diameter compensation portion for constructing a substantially circular outer cross-section of the crimping ferrule on or above the non-circular inner cross-section of the multi-core cable, wherein the assembly portion and the diameter compensation portion of the crimping ferrule are arranged continuously in the crimping ferrule and are ultimately (generally) preferably constructed as a crimping ferrule. The latter means that only the assembly portion and the diameter compensation portion constitute the crimping ferrule, preferably, the crimping ferrule is constructed without any other components on the assembly portion or the diameter compensation portion (and therefore on the crimping ferrule).

[0011] The crimping ferrule, through its assembly portion for assembling the crimping ferrule, is suitable for crimping onto the non-circular inner cross-section of a multi-core cable, i.e., for being plastically deformed onto the multi-core cable. Applications and / or embodiments of the invention are possible, wherein the assembly portion is also crimped onto the circular inner or outer cross-section of the electrical cable. Furthermore, the diameter compensation portion described herein can also be crimped onto this inner or outer cross-section of the cable. That is, the assembly portion is not mandatory but can be crimped onto a non-circular inner cross-section.

[0012] Here, the non-circular internal cross-section is preferably the internal cross-section of the multi-core cable formed by the cable shield, particularly the outer cable shield, or by a layer of the multi-core cable directly below the protective sheath. The non-circular internal cross-section should be understood as an internal cross-section that is, for example, elliptical or oval in shape compared to the shape of the outer cross-section of the multi-core cable, in addition to the circular cross-section. By means of a crimping ferrule, the circular outer cross-section of the crimping ferrule can be at least partially established on the non-circular internal cross-section of the multi-core cable. Here, the outer diameter of the circular outer cross-section is preferably within the range of the outer diameter of the protective sheath of the multi-core cable. In particular, the outer diameter of the circular outer cross-section is slightly smaller than the outer diameter of the protective sheath.

[0013] Electrical terminals, particularly shielded contact sleeves, can be fastened, especially crimped, onto the circular outer cross-section of the crimping ring. That is, the crimping ring is configured as a support sleeve. Here, the shielding of the multi-core cable can be folded radially outward onto the crimping ring, particularly onto the diameter compensation portion of the crimping ring.

[0014] On the one hand, the diameter compensation portion in the circumferential direction can be supported on / located inside the non-circular inner cross-section; on the other hand, the diameter compensation portion can be arranged inside the multi-core cable to be spaced apart from the non-circular inner cross-section. Specifically, the diameter compensation portion is supported on / located on the non-circular inner cross-section by two radially opposing inner circumferential portions. Furthermore, the diameter compensation portion is arranged on the multi-core cable to be spaced apart from the non-circular inner cross-section by two radially opposing inner circumferential portions.

[0015] The assembly section may have at least one assembly device through which the crimping ferrule can be formed on the non-circular inner cross-section of the multi-core cable. In the diameter compensation section, the first circumferential side can be connected to the second circumferential side of the crimping ferrule via the circumferential center portion. Here, the two circumferential sides can be bent toward each other, wherein the circular outer cross-section of the crimping ferrule can be formed on the multi-core cable, or on / above the non-circular inner cross-section.

[0016] Furthermore, the assembly portion of the crimping ferrule can be defined such that the non-circular internal cross-section can be clamped by the assembly portion, and the non-circular internal cross-section can elastically and / or plastically deform during this process. The diameter compensation portion of the crimping ferrule can also be defined such that only elastic deformation of the non-circular internal cross-section is possible through the diameter compensation portion, and this elastic deformation is preferably only small. The diameter compensation portion is particularly not constructed such that the internal cross-section of the multi-core cable can be plastically deformed by the diameter compensation portion, or can be punctured (cut, torn, perforated, etc.) by the diameter compensation portion.

[0017] The assembly portion and the diameter compensation portion can be arranged axially to be adjacent to each other through a gap in the crimping ring, thus being directly adjacent in the crimping ring, or thus not overlapping in the crimping ring. A single assembly device can have an assembly tongue by which a non-circular internal cross-section can be clamped. The assembly tongue can be configured as a free longitudinal portion, lug, tab, projection, wing, blade, strip, leg, or web. A single assembly device in the axial direction can be configured on a circumferential side or circumferential center portion.

[0018] In the circumferential direction of the crimping ring, two, three, four, or five assembly devices can be arranged within the crimping ring. Here, at least two or more, or all, of the assembly devices can be arranged to be substantially rotationally symmetrical or substantially anti-rotationally symmetrical within the crimping ring. Furthermore, two radially opposing assembly devices and / or their radial cross-sections can be arranged to be substantially symmetrical with respect to a point within the crimping ring.

[0019] The assembly device may have a curved assembly tongue, which is integrated into the crimping ring via a tongue base. The curved assembly tongue is preferably configured as a crimping assembly tongue. The tongue base may protrude axially from the crimping ring. Here, the corresponding tongue base may protrude axially from one of the two circumferential side surfaces or the circumferential center portion. The assembly tongue may protrude circumferentially and / or radially from the tongue base.

[0020] When crimping the crimping ring, the assembly device / the assembly tongue of the assembly device / the assembly tongue is able to: move its tongue base together within the crimping ring (see...). Figures 1 to 2 It can be crimped starting from the circumferential position on the crimping ring (see...). Figure 2 ), and / or can be pressed into a non-circular internal cross-section in a radially inward manner (see Figures 2 to 3 - The assembled tongue makes a pivotal movement in particular at its base, wherein the assembled tongue preferably moves in both the circumferential and radial directions.

[0021] For the crimped state of the crimping ferrule on / at a multi-core cable, the non-circular internal cross-section can be clamped by the assembly device and the radially opposite areas of the crimping ferrule, particularly the radially opposite assembly device. Furthermore, for the crimped state, the non-circular internal cross-section can be mounted substantially on one or both sides by a single assembly device, or mounted at a circumferential angle slightly less than approximately 72°, 90°, 120°, or 180°.

[0022] Here, the non-circular internal cross-section can be clamped by the tongue root of the crimping ferrule and the radially opposite regions, particularly the radially opposite tongue roots or the radially opposite assembly tongues. Furthermore, the non-circular internal cross-section can be clamped by the assembly tongue and the radially opposite regions of the crimping ferrule, particularly the radially opposite assembly tongues or the radially opposite tongue roots.

[0023] Furthermore, in the crimped state, the non-circular internal cross-section can be clamped by the axial portion of the diameter compensation portion and the area of ​​the crimping ring, particularly the radially opposing axial portion of the diameter compensation portion. Here, the non-circular internal cross-section can be clamped by the axial portion of the circumferential side surface and the area of ​​the crimping ring, particularly the radially opposing axial portion of the circumferential side surface.

[0024] The free periphery of the crimping ring extending in the longitudinal direction can be substantially nonexistent, extending substantially only in the longitudinal direction. As a result, the HF characteristics (signal integrity) of the crimping ring are improved. The free peripheries of the diameter compensation portions, which are opposite each other in the circumferential direction, can be constructed to be complementary and, in the crimped state of the crimping ring, are opposite each other in a substantially form-fit manner.

[0025] In the crimped state of the ferrule, in the diameter compensation section, the circumferential teeth (e.g., triangular or approximately triangular) on the circumferential side can engage between two circumferential teeth (e.g., approximately triangular or triangular) on the circumferential side opposite to the circumferential side in the circumferential direction. As a result, the stranded wires of the braided shield are better captured when the ferrule is crimped onto a non-circular inner cross-section.

[0026] In one embodiment, the crimping ferrule may be made of a metal (sheet metal) or a layer of metallized material of particularly uniform thickness. The crimping ferrule is preferably configured as a monolithic or integral crimping ferrule. The crimping ferrule may additionally have a coating, deposit, galvanized surface, etc.

[0027] The material (bonded) integral construction is understood as the construction of a crimped ferrule, wherein the various parts of the crimped ferrule are established together in a materially integral manner (welding, brazing / coppering, bonding, lamination, etc.), and the crimped ferrule preferably cannot be separated into its individual parts without damaging one of its individual parts. In this case, the bond can also be achieved through non-forced and / or forced locking connections (in cases where it is not an integral design).

[0028] The integral construction is understood as the construction of a press-fit ring, in which there is only a single component, which can only be separated by breaking said single component. This component is made from a single original part (metal sheet, blank, etc.) and / or from a single original material (molten metal), and is necessarily integral. Internal bonding is achieved through adhesion and / or cohesive forces.

[0029] In one embodiment, the circumferential center portion and / or circumferential sides may have reinforcing devices. Such reinforcing devices may be configured, for example, at least one bead. Furthermore, just prior to crimping, only the diameter compensation portion may have a generally U-shaped or V-shaped cross-section; that is, the assembled portion does not have any such shape.

[0030] In the crimping assembly method according to the invention, during the feeding step, a crimping ring is provided, comprising an axial assembly portion and an axial diameter compensation portion for crimping the crimping ring onto a non-circular inner cross-section, and subsequently, the crimping ring is crimped onto a substantially non-circular inner cross-section via its assembly portion, and the circular outer cross-section of the crimping ring is constructed onto the multi-core cable in the process via the diameter compensation portion.

[0031] When the assembly portion is crimped, the non-circular internal cross-section is clamped by at least one assembly device within the assembly portion. For this purpose, the assembly portion preferably has at least one assembly tongue through which the non-circular internal cross-section is pressed against the radially opposite area of ​​the crimping ring. Preferably, the pivotable assembly tongue is crimped in the crimping assembly method, wherein the assembly tongue is bent to present the non-circular internal cross-section. The non-circular internal cross-section undergoes elastic and / or plastic deformation during this process.

[0032] When constructing a circular outer cross-section, the first and second circumferential side surfaces of the diameter compensation portion bend toward each other. The non-circular inner cross-section described herein can undergo only elastic deformation, preferably only slight elastic deformation, particularly elastic deformation only in a single "plane". When constructing a circular outer cross-section, the free peripheries of the diameter compensation portions, which are circumferentially opposite each other, can be connected to each other in a form-fit manner and / or connected internally to each other. Here, the free peripheries are preferably directly opposite each other on a single circumference of the crimping ring.

[0033] In the crimping assembly method, the crimping ferrule is preferably crimped onto the cable shield of a multi-core cable. After the crimping ferrule is crimped onto the non-circular inner cross-section, the cable shield can be folded onto the crimping ferrule. The crimping ferrule can be configured as a crimping ferrule according to the invention.

[0034] In the method according to the invention for assembling (cable manufacturing) electrical connection devices, particularly HF connection devices, at / on a multi-core cable, in the first step of the method, a crimping ferrule is crimped onto the cable shield of the multi-core cable by a crimping assembly method according to the invention; in the second step following the first step of the method, the internal terminals (see...) Figure 5 Reference numeral 1) is attached to the inner conductor of the multi-core cable; in the third step following the second step of the method, the shielding contact sleeve (see Figure 1) is attached. Figure 5 The reference numeral 3) in the attached figure is crimped onto the crimping ferrule or cable shield and the protective sheath of the multi-core cable.

[0035] For the first step, the multi-core cable is preferably already in its intended position. In the first step, the multi-core cable, with a portion of its protective sheath removed, can be inserted into the crimping ferrule, and / or vice versa. After the first step or in the second step, the free longitudinal end portion of the cable shield can be radially folded to the outside of the crimping ferrule. The assembly of the internal terminals in the second step can be performed by methods such as crimping, (compacting) welding, brazing / soldering, etc.

[0036] The connecting device according to the invention includes internal electrical terminals, a crimping ferrule, and an electrically shielded contact sleeve, wherein the crimping ferrule is constructed according to the invention. - An entity according to the invention has an electrical connecting device, wherein the connecting device is formed according to the invention, and / or the connecting device is assembled on a multi-core cable by an assembly method according to the invention.

[0037] Here, for example, in addition to the physical housing, the entity may also have at least one mechanical, electrical, electronic, optical, and / or fluid device or apparatus. Such an entity may also be formed as, for example, devices, apparatus, connectors (twisted pair connectors, biaxial connectors, etc.), assembled multi-core cables (twisted pair cables, biaxial cables, etc.), components, circuit boards, parts, modules, units, instruments, appliances, devices, systems, etc.

[0038] The invention will now be explained in more detail with reference to the accompanying drawings, which are schematic and not drawn to scale. Parts, elements, components, units, parts, and / or patterns having the same, unique, or similar configurations and / or functions are identified by the same reference numerals in the description of the drawings (see below), the list of reference numerals, the patent claims, and the drawings. Possible alternatives not explained in the description of the invention (see above) are not shown in the drawings and / or are not definitive. Static and / or motion reversals, combinations, etc., of exemplary embodiments of the invention, or their parts, patterns, units, component portions, elements, or portions, can be further collected from the list of reference numerals and / or the description of the drawings.

[0039] In the context of this invention, features (parts, elements, components, units, parts, functions, variables, etc.) can be positively configured, i.e., present, or negatively configured, i.e., absent. In this specification (description of the invention (see above), description of the drawings (see below)), list of reference numerals, claims, and drawings), a negative feature that is not present according to the invention is not explicitly interpreted as a feature unless value is assigned to it. That is, the invention as actually made and not constructed by prior art lies in the omission of such features.

[0040] The features of this specification can be used not only in the specified manner and / or method, but also in another manner and / or method (alone, in combination, substitution, addition, independent use, omission, etc.).

Furthermore, the result can explain and / or specify the features in the patent claims in more detail.

[0041] The features in the specification can also be interpreted as optional features (given the prior art, which was initially largely unknown); that is, each feature can be considered optional, arbitrary, or preferred, i.e., non-mandatory. Therefore, it is possible to separate features (possibly including their peripheries) from exemplary embodiments, and then transfer said features to a generalized inventive concept. No particular feature (negative feature) in the exemplary embodiments indicates that the feature is optional for the invention. Furthermore, in the case of typological terms for features, genus terms for features can also be implicitly understood (possibly further subdivided into subgenus, etc.), resulting in the possibility of generalization of features, for example, considering equivalence effects and / or equivalence.

[0042] In the accompanying drawings, which are merely illustrative:

Figure 1 ), in a pre-bent state before or during crimping ( Figure 2 ), and in a crimped state without multi-core cables ( Figure 3 );

[0044] Figure 4 and Figure 5 It shows Figures 1 to 3 The crimping ring is assembled on a multi-core cable prefabricated with the crimping ring, in a cross-sectional end view facing the rear of the crimping ring. Figure 4 (It is not shown in cross-section) and in perspective view toward the multi-core cable. Figure 5 The multi-core cable is shown as being disconnected at the front and rear. Detailed Implementation

[0045] In the following, the invention will be explained in more detail through exemplary embodiments of a variant of the multi-core cable crimping ring 2 according to the invention, hereinafter referred to simply as crimping ring 2, particularly HF crimping ring 2, which is used for the electrical connection device 0 of a multi-core cable 5. Currently, the multi-core cable 5 can be formed, for example, a twisted pair cable 5, a biaxial cable 5, etc. Therefore, the connection device 0 can be formed as a multi-core connection device 0, such as a twisted pair connection device 0, a biaxial connection device 0, etc., and the crimping ring 2 can be formed as a twisted pair crimping ring 2, a biaxial crimping ring 2, etc.

[0046] Although the invention has been described and illustrated in more detail through preferred exemplary embodiments, the invention is not limited to the disclosed exemplary embodiments, but has a more fundamental nature. Other variations can be derived from and / or from the above (description of the invention) without departing from the scope of protection of the invention. The invention is generally applicable in the electrical field, in the case of electrical entities (see above). One exception here is ground power engineering. The drawings show only those spatial portions of the inventive subject matter necessary for understanding the invention. Names, such as connector and mating connector, terminal and mating terminal, etc., should be interpreted synonymously, that is, they can be used interchangeably.

[0047] Figures 1 to 3 The crimping collar 2 according to the invention is shown in three consecutive stages of a method for assembling the crimping collar 2 by crimping. Figure 1 The roll is flat at point 23. Figure 2 : Pre-bent, still on roll 23; Figure 3 (It is crimped and separated from the roll 23). The crimping collar 2 currently and ultimately includes a first front axial portion 21 as an axial assembly portion 21 and a second rear axial portion 22 as an axial diameter compensation portion 22. Of course, the crimping collar 2 may optionally have other axial portions. Here, the two axial portions 21, 22 are configured as a single and preferably integral layer of material of the crimping collar 2.

[0048] The axial assembly portion 21 is used to assemble the crimping collar 2 onto the generally non-circular inner cross-section 50 of the multi-core cable 5. See also Figure 4 and Figure 5 The multicore cable 5 currently comprises, radially from the inside out: two electrically insulated inner conductors 51, 52; an inner cable shield 54 (e.g., configured as a shielding foil 54); a cable shield 55 radially located thereon (e.g., configured as a braided shielding conductor 55); and a protective sheath 57 radially on the outside. Of course, another construction of the multicore cable 5 can be used.

[0049] Axial diameter compensation portion 22 is used to construct a basic circular outer cross-section 20 of the crimping collar 2 on / above the non-circular inner cross-section 50 of the multi-core cable 5; see also Figure 4 and Figure 5 The assembly portion 21 and the diameter compensation portion 22 are arranged continuously in the axial direction Ar as a press-fit collar 2. In particular, the assembly portion 21 transitions seamlessly and / or integrally into the diameter compensation portion 22.

[0050] The diameter compensation portion 22 is preferably composed of substantially a single (circumferential) material layer 220, 221, 222 (metal sheet), and includes a circumferential central portion 220, which preferably integrally connects the (first) circumferential side surface 221 of the crimping collar 2 to the (second) circumferential side surface 222 of the crimping collar 2. The center of the circumferential central portion 220 is preferably aligned with the crimping opening or crimping groove of the crimping collar 2 (see...). Figure 2 Radial relative.

[0051] The diameter compensation portion 22 has a range in the axial direction Ar, which also corresponds to the axial direction Ar of the connecting device 1 and the multi-core cable 5. Furthermore, depending on its crimping state (see...), Figures 1 to 3 The diameter compensation portion 22 has a range in the radial direction Rr and a range in the circumferential direction Ur, wherein these directions Rr and Ur also correspond to the directions Rr and Ur of the connecting device 1 and the multi-core cable 5.

[0052] The crimping collars 2 on the two circumferential sides 221, 222 of the diameter compensation portion 22 each have at least one (crimping) assembly device 211, 212, so as to be abutted towards the front in the axial direction (the direction of the plug face of the connecting device 1). The crimping collars 2 can be formed on the non-circular inner cross-section 50 by means of the assembly devices 211, 212, that is, they can be crimped onto the non-circular inner cross-section 50.

[0053] In this document, assembly devices 211 and 212 form the assembly portion 21 of the crimping collar 2. Depending on the number of assembly devices 211 and 212, at least one such assembly device may also be adjacent to the circumferential center portion 220 in the axial direction Ar. - Here, all assembly devices 211 and 212 are preferably arranged on a single axial side of the crimping collar 2.

[0054] The corresponding assembly devices 211 and 212 have (press-fit) assembly tongues 2115 and 2125 (see...) Figure 2 It can be bent into the crimping opening or crimping groove of the crimping collar 2. The assembly tongues 2115 and 2125 can be crimped mainly or substantially in the radial direction Rr, wherein displacement of the assembly tongues 2115 and 2125 in the axial direction Ar is not possible. The corresponding assembly devices 211 and 212 are integrally provided on the tongue roots 2110 and 2125, which are integrally constructed with the diameter compensation portion 22 and are currently integrally constructed with the corresponding circumferential sides 221 and 222.

[0055] Currently, the corresponding tongue bases 2110 and 2120 are configured in the shape of lugs and are configured as generally thinner (material thickness of the pressing ring 2) and curved cuboids. Here, disregarding their (material) thickness, the corresponding tongue bases 2110 and 2120 extend along the axial direction Ar and the circumferential direction Ur. Here, the curvature of the corresponding tongue bases 2110 and 2120 corresponds to the curvature of the region of the diameter compensation portion 22 directly adjacent to the tongue bases 2110 and 2120, or corresponds to the curvature of the corresponding circumferential side surfaces 221 and 222 (see...). Figure 3 ).

[0056] Currently, the corresponding assembly tongues 2115 and 2125 are configured in the shape of lugs and are configured as generally thinner (material thickness of the crimping ferrule 2), straight cuboids. However, curved cuboids can be used here. The latter means, for example, that the corresponding assembly tongues 2115 and 2125 can accommodate the curvature of a non-circular internal cross-section 50. Without considering their (material) thickness, depending on the crimping state of the crimping ferrule 2, the corresponding assembly tongues 2115 and 2125 extend primarily or substantially in the circumferential direction Ur. Figure 2 Or it extends in the circumferential direction Ur and the radial direction Rr. Figure 3 ).

[0057] By means of the assembly tongues 2115 and 2125, the non-circular inner cross-section 50 can be clamped, in which way the crimping ferrule 2 can be crimped onto the multi-core cable 5, and when crimping, the diameter compensation portion 22 or the circular outer cross-section 20 of the crimping ferrule 2 can also be formed (making the circumferential sides 221 and 222 bend toward each other). Therefore, it is ensured that the crimping ferrule 2 can be firmly positioned on the multi-core cable 5 and will not move on it. The radial force provided on the crimping ferrule 2 by the shielding contact sleeve 3, especially the radial force crimped on the crimping ferrule 2, is transmitted to the circular outer cross-section of the crimping ferrule 2, so that the inner conductor of the multi-core cable 5 is not squeezed.

[0058] In the method according to the invention for assembling by crimping a crimping ring 2 onto a multi-core cable 5, in the feeding step, a specific crimping ring 2 and a specific (pre-)prepared multi-core cable 5 are provided. Subsequently, the crimping ring 2 is crimped onto the substantially non-circular inner cross-section 50 of the multi-core cable 5, for example, after the protective sheath 57 has been peeled off (i.e., partially or completely peeled off, for example, pulled off or removed) from the multi-core cable 5. Figure 4 and Figure 5 This is repeated based on the number of crimping rings 2. - The crimping assembly method here may be a temporary part of the assembly method of the electrical connection device 0 explained below.

[0059] In the crimping assembly of a single crimping collar 2, the multi-core cable 5 moves from above into the top-opening crimping collar 2 through its non-circular inner cross-section 50, and / or vice versa, and / or from the rear into the rear-opening crimping collar 2, and / or vice versa. Essentially immediately thereafter, the crimping collar 2 is crimped onto and / or onto / above the non-circular inner cross-section 50, or crimped onto / on the multi-core cable 5. That is to say, the crimping collar 2 is crimped onto the axial portion of the multi-core cable 5 having this non-circular inner cross-section 50.

[0060] To construct the circular outer cross-section 20 of the crimping collar 2 here, on the one hand, the circumferential side surfaces 221, 222 are bent toward each other until their free peripheries substantially abut each other in the circumferential direction Ur (crimping). On the other hand, the assembly devices 211, 212 clamp the multi-core cable 5 between the assembly devices 211, 212 through the non-circular inner cross-section 50 of the axial portion of the multi-core cable 5 (crimping), thereby mounting the crimping collar 2 on the non-circular inner cross-section 50 of the multi-core cable 5 (assembly devices 211, 212) and on / above the non-circular inner cross-section 50 of the multi-core cable 5 (circumferential side surfaces 221, 222).

[0061] In this process, the assembly tongues 2115 and 2125 are preferably bent radially inward onto the axial portion of the multi-core cable 5 having a non-circular internal cross-section 50. Figures 2 to 3 Up to 5), so that the axial portion is clamped between the assembly tongues 2115 and 2125. When the circular outer cross-section 20 of the crimping collar 2 is constructed, the circumferential sides 221 and 222, and therefore the tongue roots 2110 and 2120, are further bent toward each other. Figures 2 to 3 (5) This further clamps the axial portion between the tongue bases 2110 and 2120. Subsequently, in the crimped state of the crimping collar 2, the free longitudinal end portion of the cable shield 55 can preferably be placed on the crimping collar 2 in a fully circumferential manner.

[0062] Before the circumferential sides 221 and 222 bend toward each other and press against the crimping collar 2, the circumferential sides 221 and 222 can protrude from the circumferential center portion 220 in a substantially straight line. That is, the corresponding circumferential sides 221 and 222 extend tangentially from the circumferential center portion 220. The circumferential sides 221 and 222, and preferably the tongue bases 2110 and 2120, are given their curved shape only when the crimping collar 2 is pressed against, while the assembly tongues 2115 and 2125 retain their basic shape rather than their position.

[0063] In the assembly method of the connecting device 0 according to the invention, the partial stripping of the protective sheath 57 of the multi-core cable 5 preferably occurs first in step I, where the cable shield 55 (preferably braided shield conductor 55) of the multi-core cable 5 is exposed. Of course, it can also be completely pulled off or partially or completely removed. Subsequently, the crimping ferrule 2 is crimped onto the free longitudinal portion (the crimping assembly method of the crimping ferrule 2 as a temporary part of step I); see above.

[0064] In the second step II following the first step I of the assembly method, the remaining free longitudinal end portion of the multi-core cable 5 is first prepared for assembling the internal (HF) terminals (see...). Figure 1 Here, depending on the multi-core cable 5, the dielectric or corresponding electrical insulation portion of the inner conductors 51, 52 of the multi-core cable 5 is removed from the remaining free end portion that is slightly spaced from the folded portion of the crimping ferrule 20 or the cable shield 55. Subsequently, the inner terminals 1 (preferably two) are assembled to the multi-core cable 5.

[0065] In the third step III following the second step II of the assembly method, the external electrical (HF) (crimping) terminal 3, particularly the shielded contact sleeve 3, can be crimped onto the multi-core cable 5. Here, the shielded contact sleeve 3 is crimped onto the folded portion of the crimping ring 2 or the cable shield 55, and further crimped onto the protective sheath 57 of the multi-core cable 5 at the rear. In this document, the pre-prepared multi-core cable 5 is moved from top to the top-open shielded contact sleeve 30, and / or vice versa, and / or from the rear to the rear-open shielded contact sleeve 30, and / or vice versa. - These steps I, II, and III are repeated depending on the number of connecting devices.
