Description

Technical Field

[0001] The invention relates to an electrical ferrule, in particular an HF ferrule, for an electrical connection device, in particular an HF data connection device, preferably for the automotive industry. The invention also relates to an electrical contact member for an electrical contact device or an electrical connector, to an electrical connection device for an electrical connector, to an electrical connector and to an electrical entity, preferably for the automotive industry, respectively. Background Art

[0002] In the electrical field (electronics, electrical engineering, electrical, power technology, etc.), there are a large number of known electrical connector components or connector devices, socket connectors, pin connectors and / or hybrid connectors, etc. Hereinafter referred to as (electrical) connectors (also called: mating connectors), they are used to transmit current, voltage, signals and / or data at a wide range of currents, voltages, frequencies and / or data rates. In the field of low, medium or high voltages and / or currents, in particular in the automotive industry, such connectors must ensure that power, signals and / or data are transmitted in a mechanically stressed, warm, possibly hot, contaminated, humid and / or chemically aggressive environment within a short period of time, continuously, repeatedly and / or after a relatively long period of inactivity. Due to the wide range of applications, a large number of specially designed connectors are known.

[0003] Such a connector, and possibly a housing associated therewith (e.g. in the case of a connector component or a connector device) or a higher-level housing (e.g. in the case of a connector device), can be mounted on a power line, a cable, a cable harness, etc. hereinafter referred to as a pre-assembled (electrical) cable (also referred to as: electrical entity), or on / in an electrical device or component, such as on / at a housing of an electrical (electrical), optoelectronic or electronic part or a corresponding assembly, etc. (electrical entity), at / in a lead frame, at / on a circuit board, etc. (electrical entity).

[0004] If the connector (with or without a housing) is located on a cable, line or cable harness, this is also called a flying lead (insertion type) connector or a plug, socket or coupling; if it is located on / in an electrical, optoelectronic or electronic component, assembly, etc., this is also called a connector device, such as a (built-in / attached) connector, a (built-in / attached) plug or a (built-in / attached) socket. In addition, the connectors on such devices are often called (plug) holders, box header connectors, pin strips or headers. In the context of electrical energy technology (generating, converting, storing and transmitting high-voltage current within the power grid, preferably using three-phase high-voltage transmission), cable accessories are usually mentioned here due to their relatively complex structure.

[0005] Such connectors must ensure a trouble-free transmission of electrical power, wherein the mutually corresponding and partly complementary connectors (connector and mating connector) generally have locking means and / or fastening means, which are used to lock and / or fasten the connector on / in the mating connector and vice versa in a permanent but generally removable manner. In addition, the electrical connection device for the connector, for example comprising or at least having the actual contact member (terminal; generally formed as a single piece of material or formed integrally, such as a contact element, etc.) or the contact device (terminal; generally formed as a plurality of parts, two parts, a single part, a single piece of material or an integral tie rod, such as a single or multi-part (crimped) contact device), must be securely held therein. In the case of (already) preassembled cables, such a connection device can be provided as a connector (see above), that is to say without a housing, for example in the manner of flying leads.

[0006] There is a constant effort to improve electrical connectors and their connection devices, in particular due to miniaturization to make them more robust, to design them more efficiently and to produce them at a lower cost. For HF data connectors (HF: High Frequency, defined here as: transmission frequencies greater than 3 to greater than 300 MHz, and well into the GHz range (about 150 GHz)), other rules apply here than for conventional data connectors (defined here as: transmission frequencies below about 3 MHz), since the wave characteristics of electricity are particularly evident in HF technology. In particular due to their configuration on the cable and / or their final diameter, in particular HF cables, the ferrules (support sleeves) have a significant influence on the impedance of the connection device.

[0007] Conventional ferrules of a particular type are only used for a single cable type, e.g. from a single manufacturer, or only for a single actual cable size (cable diameter of the inner layer, e.g. coaxial cable, twinaxial cable, etc.). For other cable types or cable sizes, other types of ferrules must be used. In addition to the different cable diameters of the two cable types, the varying cable diameters during the pre-assembly process of the cables are also a problem. This is, for example, because of at least one mechanical property of the cable (finish, hardness, compressibility, elasticity, etc.), in particular its relatively large inner insulation layer. Furthermore, this becomes even more difficult because cables of the same diameter from different manufacturers have different properties, especially in terms of the insulation layer. Furthermore, there are the tolerance issues involved.

[0008] The object of the present invention is to provide an improved electrical ferrule, possibly suitable for HF, an improved electrical connection device, possibly suitable for HF and an improved electrical connector, possibly suitable for HF, preferably for the automotive industry. Here, the ferrule should be designed for different cable diameters and / or be able to adapt to changes in cable diameter during the pre-assembly process of the cable. In addition, it is intended that the ferrule, the connection device and the connector can be produced at a low cost compared to their subsequent use and have a simple structure and / or be easy to handle. Summary of the invention

[0009] The objects of the invention are achieved by an electrical ferrule, in particular an HF ferrule, for an electrical connection device, by an electrical contact member, for an electrical contact device or an electrical connector, by an electrical connection device, for an electrical connector, by an electrical connector and by an electrical entity, preferably for the automotive industry, respectively. Advantageous developments, additional features and / or advantages of the invention will follow from the dependent claims and the following description.

[0010] The ferrule according to the invention comprises only two side parts, which extend in the axial direction of the ferrule, are opposite to each other in the radial direction of the ferrule and are connected to each other in the circumferential direction of the ferrule by a circumferential center part. According to the invention, at least one self-locking of the ferrule in the axial direction is or can be provided by the side parts, by which self-locking the ferrule installation diameter (and compressed installation diameter) is variably formed for its installed state (and compressed installation state) on the cable, in particular the HF cable. Here, the ferrule can be formed as a crimping ferrule, which then involves not only the installation diameter, but also the crimping height.

[0011] Here, by analogy with the side parts, the circumferential parts also extend in the axial direction, while by analogy with the circumferential parts, the side parts also extend in the circumferential direction, depending on the state of the collar (open state, not pre-mounted state, not mounted state and / or compressed mounted state, that is to say the position of its side parts). In addition, in the circumferential direction, the first side part merges into the circumferential center part, and the circumferential center part merges into the second side part. Here, the circumferential center part can have a greater, equal or smaller stiffness and / or thickness than the side part or the two side parts.

[0012] Here, the expanded outer base area of ​​the collar can be substantially or mainly formed as a rectangle. The collar is preferably formed or composed only of a flat and / or thin layer of material (e.g. a metal sheet). Here, the collar can be punched or die-cut and then possibly bent into shape. In addition to its practical purpose of being mounted on the cable, such a collar is thus formed with its axial end faces (front and rear) open in both its open and closed states. In the open state of the collar, its cross-section is preferably substantially U-shaped or V-shaped. In the mounted state and / or compressed mounted state of the collar (see below), its cross-section is preferably substantially O-shaped.

[0013] The collar is preferably formed as an integral collar. An integral form is to be understood as a form of collar in which there is only a single component which can only be separated by destruction. This component is made of a single original piece (metal sheet, blank, etc.) and / or a single original compound (molten metal, polymer solution, etc.), which is necessarily indispensable in itself. It is held together internally by adhesion and / or polymerization. The collar itself can be formed of metal, metal alloy, plastic or plastic-metal composite. If the collar is made of plastic, it is preferably metallized with metal or metal alloy inside and outside. The collar can additionally have at least one coating, deposition, galvanizing, etc.

[0014] The setting of a specific installation diameter of the collar can first be carried out by a specific self-locking of the collar in the circumferential direction, wherein such a self-locking can be formed by a single individual locking, for example two latching members, or a plurality of individual locking, for example two latching members each. That is, the self-locking can include a plurality of individual lockings, which can be arranged, for example, distributed between the sides in the axial direction and / or in the circumferential direction. That is, no matter how many individual locking and / or latching members there are, a self-locking is or can be arranged, which is related to the specific installation diameter of the collar.

[0015] The installation diameter or installation inner diameter of the collar is understood to mean at least one diameter. Here, in particular, the main or substantially all installation diameters or installation inner diameters of the collar can be variably formed. In particular, the collar thus has no other parts connected to it as a monolithic material or as a whole in the axial direction, such as electromechanical contacts arranged indirectly or directly thereon.

[0016] It is possible that the collar is closed or closable on the cable by at least one circumferential direction of its self-locking. The self-locking arrangement can be effective only in one circumferential direction or in both circumferential directions. If the self-locking arrangement is effective only in a single circumferential direction, the installation diameter of the collar can be gradually further reduced or further increased over time.

[0017] If the self-locking arrangement is effective in both circumferential directions, then the installation diameter is essentially fixed except for the permanent elastic or plastic deformation of the collar. In the self-locking arrangement, the two free longitudinal end portions of the side portion can engage each other in the circumferential direction and / or overlap one another in the radial direction. The latching members of the first side portion and the second side portion, which correspond to each other, are particularly formed to be partially complementary to each other and / or to be form-fitted to each other in certain sections.

[0018] In a variant of the invention, the collar can have a plurality of configurable self-locks, wherein when the collar is arranged on the cable (see cable tie), the installation diameter can be set by any self-lock of the self-lock. The collar can have exactly two or a certain number of configurable self-locks, by which exactly two or a certain number of installation diameters can be set on the cable. Here, the self-locking is preferably formed in a manner that is effective in both circumferential directions. As described above, this configurable self-locking consists of a single individual locking or a plurality of individual lockings, respectively. In addition to setting the cable diameter, the self-locking of the collar can also be set sequentially in the circumferential direction by the side.

[0019] For self-locking, the first side may have a single latching member and the second side may have exactly two or one / said specific number of latching members. The latching member of the first side may be formed as a latching protrusion, which is formed by a free circumferential portion from the first side. Thus, the latching protrusion may be formed, for example, in an L-shape, a T-shape, an O-shape, a mushroom shape, etc.

[0020] The latching member of the second side portion can be configured as a latching recess in the second side portion, wherein the latching recesses preferably merge into each other without interruption. Here, by analogy with the positive latching protrusion of the first side portion, the latching recess is set to the corresponding negative in the second side portion. In addition, the latching recesses that merge into each other without interruption are directly fluidically connected. And, of course, the latching members of the second side portion that merge into each other without interruption are arranged in a row in the circumferential direction.

[0021] At least in the mounted state of the ferrule on the cable, and apart from the extent of the ferrule in the axial direction and its material thickness in the radial direction, the latching projections (latch members) and / or the latching recesses (latch members) extend only in the circumferential direction. Additionally or alternatively, in this case, the latching projections (latch members) can essentially completely (form-fittingly) fill the corresponding latching recesses (latch members).

[0022] In a variant of the invention, the collar can preferably have exactly one self-locking, which is or can be provided, by means of which, preferably in the mounted state of the collar, exactly one substantially maximum mounting diameter (not: compressed mounting diameter) is or can be provided on the cable. Here, the self-locking is preferably formed so that it is only effective in a single circumferential direction. As described above, this configurable self-locking can consist of a single individual locking or a plurality of individual lockings, respectively. The self-locking that is or can be provided can be effective in the collar so that in the mounted state of the collar on the cable, on the one hand, the maximum mounting diameter of the collar is not increased again, but on the other hand, the maximum mounting diameter of the collar can still be reduced (in the direction of its compressed mounting diameter).

[0023] As a result, for example, the impedance of the electrical connection device with the ferrule can be set on the outer conductor of a coaxial cable or a twinaxial cable only in the area of ​​the ferrule, only in the last installation step, for example the crimping of the shield contact sleeve. This is achieved, for example, by the crimping diameter of the shield contact sleeve. This enables the end product to meet the performance requirements. The material of the ferrule, for example, preferably uncoated high-grade steel, has a particularly high to very high tensile strength in order to assume the function of the ferrule as a supporting sleeve. The material thickness is preferably less than but substantially equal to: 0.35 mm, 0.3 mm, 0.25 mm, 0.2 mm, 0.19 mm, 0.18 mm, 0.17 mm, 0.16 mm or 0.15 mm.

[0024] The collar can also be formed such that, starting from its form in the installed state, it can be radially compressed for a compressed installed state on the cable, for which purpose the collar is preferably formed or can be formed in a double-layered manner in the circumferential section. That is to say, for example, the form of the collar which is closed in the circumferential direction can be further closed, thereby reducing the inner diameter and possibly also the outer diameter of the collar. Additionally or alternatively, in the installed state, an inherent flywheel (gap) is provided in the collar between the side parts, wherein the side parts are arranged to be displaceable relative to each other, preferably initially only in one circumferential direction.

[0025] The side parts may each have a latching member for self-locking of the collar, wherein the self-locking is provided in the mounted state of the collar. In addition, the latching member may be effective only for an increase in the mounting diameter of the collar. In addition, the latching member may allow a reduction in the mounting diameter of the collar. That is, the latching member constitutes a member that stops the mutual displaceability of the side parts in the circumferential direction, so that the displaceability of the side parts in the direction of a reduction in the mounting diameter of the collar is still possible.

[0026] The latching members of the first side may be formed as radially outer hooks and the latching members of the second side may be formed as radially inner hooks. That is, the outer hooks are formed as latching hooks which extend radially outwards from the first side and the inner hooks are formed as latching hooks which extend radially inwards from the second side. During an initial transition of the collar from its mounted state to its compressed mounted state, the latching members release each other. For example, the compressed mounted state of the collar may be assumed when a contact member, such as a shielding contact sleeve, is mounted on the collar, in particular when crimped.

[0027] The inherent flywheel can be provided as a sliding bearing extending in the circumferential direction between the two side parts (a circumferential sliding bearing, not a radial sliding bearing with a rotating bearing counterpart). In addition, in the mounted state and / or in the compressed mounted state, the latching member can be substantially in line with the corresponding outer side of the collar. That is, the height of the latching member is in the region of the material thickness of the collar.

[0028] The collar can be formed as a fully elastic, partially plastic or substantially plastically deformable collar. In particular, the collar can be formed as a substantially elastic and / or partially plastically deformable, mechanically prestressed spring collar. As a result, the turned-over longitudinal end portion of the shield conductor can be made to bear against the spring collar in a radially outwardly prestressed manner. The collar can have a reinforcing bead, which preferably runs in the circumferential direction (see below).

[0029] In one embodiment, the impedance compensation member can be arranged in at least one side or in the corresponding side. Additionally or alternatively, the impedance compensation member can be arranged in the circumferential center part. The corresponding impedance compensation member is particularly provided as a substantially rectangular channel (air gap, air cushion) in the corresponding side and / or circumferential center part. Here, the impedance compensation member, in particular the channel, is formed and dimensioned so as to improve the impedance of the collar. In this way, the formation helps to adjust the low impedance area caused by the compression of the cable by the dielectric air gap or dielectric air cushion in the barrel of the collar. Therefore, the HF performance of the HF plug connection can be improved.

[0030] In the ferrule, in particular in the circumferential center portion, at least one fixing hook or retaining hook may be provided which protrudes inwardly in the radial direction. By means of such fixing hooks, the ferrule can be fixed on the cable during pre-assembly of the cable. Here, a plurality of fixing hooks may be arranged in the corner portions of the impedance compensation member in the circumferential center portion. Preferably, two or four such fixing hooks are arranged in the ferrule. It is preferred here that the ferrule is shaped such that, during crimping of the ferrule, the fixing hooks provide support via the crimping tool, in particular the crimping anvil. That is, it is also preferred that the impedance compensation member is dimensioned such that it does not protrude beyond the crimping tool during crimping of the ferrule.

[0031] - / The edge of the impedance compensation member of the first side can be formed as a latching member of the first side. The latching member of the first side can be formed as a circumferential lug, which extends radially outwards from the bending plane of the first side and may have a tangential portion. - / The edge of the impedance compensation member of the second side can be formed as a latching member of the second side. The latching member of the second side can also be formed as a radial hook, which extends radially inwards from the bending plane of the second side and may have a tangential portion. In the installed state, the radial hook is seated on the preferably inner axial side of the circumferential lug in a substantially form-fitting manner with a preferably outer axial side, in particular in a form-fitting manner. The axial sides that are respectively opposite in the circumferential direction are substantially free.

[0032] In the open state of the collar, the circumferential center portion may have a smaller radius of curvature than the circumferential portion of the side directly adjacent in the circumferential direction. This can of course also be related to the two side portions. As a result, the collar is given a cross-section which, in front view, is a pot-shaped or U-shaped cross-section in cross-section, with a relatively straight or relatively (relative to the directly adjacent circumferential portion of the side) less curved cross-piece between its two legs. In other embodiments, the collar may be in the form of a circular arc or in the form of an elliptical arc in cross-section or in front view. Of course, oval arc ring portions can also be used.

[0033] The side portion can be formed as a substantially straight line or slightly inwardly curved in its side circumferential center portion. That is, for example, so that the side circumferential center portion is arranged substantially tangentially relative to the circumferential portion directly adjacent in the direction of the circumferential center portion in the circumferential direction. The collar can have an anti-collision lug protruding outward in the circumferential direction on only one side portion. The anti-collision lug is used to prevent the free circumferential ends of the side portion from colliding with each other during the crimping of the collar. During the crimping of the collar, the first side portion can be radially pressed under the second side portion by the anti-collision lug, which is actuated / triggered by a crimping tool, for example. In addition, for / in the installed state and / or in the compressed installed state, by the anti-collision lug, a self-locking of the collar in the circumferential direction is set or can be set.

[0034] In particular, the reinforcing beads are arranged on the axial end portions or the reinforcing beads, which are preferably formed as elongated reinforcing beads, are arranged in both axial end portions. It is preferred here that the corresponding reinforcing beads extend from the side portion on the circumferential center portion and through the impedance compensation component of the circumferential center portion into the other side portion, wherein the two longitudinal ends of the reinforcing beads are located in the side portion. In particular, it is preferred that the collar is formed for its intended use such that one circumferential end of such a reinforcing bead is not in mechanical contact with the corresponding circumferential end of the side portion in the compressed mounted state (discontinuous diameter reduction).

[0035] In addition, the circumferential transition region from the circumferential center part into the side part can have a reinforcing bead axially flush with the impedance compensation component, that is to say, in particular, between the impedance compensation component of the circumferential center part and the corresponding impedance compensation component of the side part. Here, at least one, in particular two or more such reinforcing beads can be arranged in the circumferential transition region, in particular symmetrically with respect to the axial center circumferential center line; this can also apply to the above-mentioned reinforcing beads. Such a reinforcing bead can start on / in the impedance compensation component and possibly extend to the impedance compensation component directly adjacent to it in the circumferential direction. In addition to the open inner space of the collar, two impedance compensation components directly adjacent in the circumferential direction can in this case be connected to the fluid via at least one reinforcing bead.

[0036] The contact member according to the invention has an electromechanical contact portion formed as a single piece of material or integrally formed and a collar, wherein the collar is formed according to the invention. The connection device according to the invention has at least one electrical terminal and a collar or contact member, wherein the collar or contact member is formed according to the invention.

[0037] Here, the connection device can be formed as a coaxial connection device, a biaxial connection device (in each case in three parts), etc. The terminal can be formed as an internal male terminal or an internal female terminal. In addition, the terminal can be formed as an external shielding contact sleeve. Preferably, the connection device has an internal terminal and an external terminal.

[0038] The connector according to the invention has a connector housing, a collar, a contact member or a connection device, wherein the collar, the contact member or the connection device is formed according to the invention. Here, the connector can be formed as a coaxial connector, a twinax connector, etc. The entity according to the invention has a contact member, a connection device or a connector, wherein the contact member, the connection device or the connector is formed according to the invention.

[0039] Here, the entity may for example have at least one mechanical, electrical, electronic, optical and / or fluidic component or device in addition to the physical housing. Such an entity may for example (also) be formed as a component, device, preassembled cable, subassembly, circuit board, component part, module, facility, equipment, unit, installation, system, etc.

[0040] The invention is explained in detail below based on exemplary embodiments and with reference to the attached schematic and not to scale drawings. Parts, elements, components, units, components and / or diagrams with the same, univocal or similar form and / or function are identified by the same reference numerals in the description of the drawings (see below), in the list of reference numerals, in the patent claims and in the drawings. Possible alternatives can also be inferred from the list of reference numerals and / or the description of the drawings, which are not explained in the content of the invention (see above), are not shown in the drawings and / or are not exhaustive, static and / or kinematic inversions, combinations, etc. of exemplary embodiments of the invention, or their components, diagrams, units, components, elements or parts thereof.

[0041] In the present invention, a feature (part, element, component, unit, component part, function, dimension, etc.) may be embodied positively, i.e., present, or negatively, i.e., absent. In the present application documents (description (content of the invention (see above), description of the drawings (see below)), list of figure numerals, patent claims, drawings), a negative feature is not explicitly interpreted as a feature when its absence is not essential according to the present invention. That is, the invention actually created, rather than the invention constructed according to the prior art, includes the omission of the feature.

[0042] The features of the present application document may be used not only in the manner specified, but also in a different manner (isolated, combined, replaced, added, independent, omitted, etc.). In particular, features in the patent claims and / or the specification may be replaced, added or omitted in the description, the list of reference numerals, the patent claims and / or the drawings based on the reference numerals and the features associated therewith, and vice versa. Furthermore, features may therefore be described and / or elaborated more specifically in the patent claims.

[0043] Features of the description may also be interpreted as optional features (in view of the (initially largely unknown) prior art); in other words, any feature may be considered as optional, arbitrary or preferred, i.e. non-binding. A feature (possibly including its periphery) may thus be separated from an exemplary embodiment, wherein the feature may then be transformed into a generalized inventive concept. The absence of a feature in an exemplary embodiment (negative feature) indicates that the feature is optional for the invention. Furthermore, technical terms for features may also be interpreted as generic terms for features (possibly further hierarchically decomposed into lower-level terms, etc.), so that features may be generalized, e.g. with regard to equivalent effects and / or equivalence.

DETAILED DESCRIPTION

[0050] The female connector 10 according to the present invention is as follows according to two variations of the electrical collar 20 (variation 1: Figure 1 and Figure 2 , variant 2: Figures 3 to 19 ) more specifically explain the invention, in particular an HF collar 20, for an electrical connection device 1, in particular an HF data connection device 1, preferably for the automotive industry. Although the invention is more specifically described and explained in more detail by means of a preferred exemplary embodiment, the invention is not limited to the disclosed exemplary embodiments, but has a more basic nature.

[0051] Other variations may be obtained from this and / or from the above (description of the invention) without departing from the scope of protection of the invention. In the case of electrical entities (see above), the invention can be generally used in the electrical industry. The exception here is electrical energy technology. Only those spatial parts that are necessary for the understanding of the invention for the purpose of the invention are shown in the drawings. Terms such as connector and mating connector, terminal and mating terminal, etc. should be understood as synonymous, that is to say, can be interchanged with each other.

[0052] The connecting device 1 shown as an example (see Fig.13) comprises a first or inner electrical terminal 10, an electrical collar 20 according to the invention, a second or outer electrical terminal 40, and a dielectric 30 between the inner terminal 10 and the outer terminal 40. Here, the terminal 10 may be formed as a male or female terminal 10 and / or the terminal 40 may be formed as a shielding contact sleeve 40. Of course, other forms of connection device 1 may be used.

[0053] The connection device 1 is mounted or can be mounted on a cable 50 (and a cable harness 50), in particular an HF cable 50 (an electrical entity 5, in particular an HF entity 5, as a preassembled cable 5). In this case, the cable 50 can be formed as a twinaxial cable ( Figure 1 and Figure 2 )、Coaxial Cable( Fig. 9 , 10 , 13 and 14), etc. In this case, the cable 50 has at least a central inner conductor 51, an inner insulator 52, an outer conductor 53 and a protective sheath 54. Of course, other configurations of the cable 50 can be used. The connecting device 1 can be installed in the electrical connector 0 (in Fig.13 ), in particular a HF connector 0, preferably a HF data connector 0, such as a twinaxial connector (0), a coaxial connector 0, etc., for example in its connector housing.

[0054] In this case (see Fig.13 ), the first or inner terminal 10 includes an electromechanical contact portion 11, an electromechanical fastening portion 12 and an electromechanical connection portion 13. Of course, another form can be used. In addition, the second or outer terminal 40 includes an electromechanical contact portion 41, a mechanical fastening portion 42 and an electromechanical connection portion 43. Again, of course, another form can be used. Here, the ring 20 (which can preferably be radially mounted on the outer conductor 53 of the cable 50, in particular the shielding conductor, and radially mounted below the outer terminal 40, in particular the shielding contact sleeve 40) can be formed as a crimpable or non-crimpable ring 20.

[0055] The ferrule 20 has a circumferential center portion 23 in the center in the circumferential direction Ur and peripherally has side portions 21, 22 on both sides, which can be formed as crimping side portions 21, 22. The cross section of the ferrule 20 is shown in FIG. Figure 1 ) on the open state O (see Figures 3 to 5 ) and / or in its pre-installed state V (first variant) is substantially U-shaped or substantially V-shaped, and / or in its cable 50 (see Figure 2 , Figures 7 to 10 ) in the installation state M on the cable 50 ( Figures 11 to 14), the cross section of the collar 20 extending substantially in the axial direction Ar of the collar 20, apart from the material thickness of the collar 20. Apart from relatively small means (304, 306, 308, 310, 318, 320, 328) extending in the radial direction Rr of the collar 20, the collar 20 preferably has no portion extending in the radial direction Rr.

[0056] According to the invention, at least one self-locking 201, 202 (first variant); 300 (second variant) of the collar 20 in the circumferential direction Ur is provided or can be provided by the collar 20. In this case, the provision of the self-locking 201, 202; 300 can be effective only in one circumferential direction Ur (second variant, preferably a single self-locking 300) or in two circumferential directions Ur (first variant, preferably at least two self-locking 201, 202), i.e., preventing the inherent movement of the collar 20 in at least one (that is, exactly one or two) circumferential directions.

[0057] As a result, for the installation state M (two variants), kM (second variant) on the cable 50, the collar 20 installation diameter Md (two variants), kD (second variant) is variably formed. To this end, the two free longitudinal end portions of the side portions 21, 22 opposite in the circumferential direction Ur can be engaged with each other in the circumferential direction Ur (first variant) or superimposed on each other in the radial direction Rr (second variant) and can be radially engaged with each other. The first variant of the present invention is suitable for different cable diameters (see above), for example. And the second variant of the present invention can be used, for example, for cable diameters that vary during the pre-assembly process of the cable 50 (see above).

[0058] Figure 1 (pre-installation state V of the collar 20) and Figure 2 ((final) mounted state M of the collar 20) shows the embodiment of the invention in the case of a biaxial connection device 1 (similar to Fig.13 ) of the electrical twin-axial cable 50 when used on the first variant of the electrical ring 20; of course, the first variant for another cable can be used, such as a coaxial cable 50 (see, Figures 3 to 14 ), etc. In this case, the ferrule 20 has exactly two self-lockings 201, 202, so that the ferrule 20 is suitable for two different installation diameters Md of the ferrule 20 on the cable 50. Of course, the ferrule 20 can also have more than two self-lockings 201, 202 for corresponding multiple installation diameters Md.

[0059] The mounting diameters Md of the collar 20 can be arranged sequentially in the circumferential direction Ur, for which purpose the first side portion 21 has a single latching member 210, preferably formed as a latching protrusion 310, and the second side portion 22 has a corresponding plurality of latching members 221, 222 (in the present case two), preferably formed as latching recesses 221, 222. The latching recesses 221, 222 are preferably arranged in the side portion 22 one after the other at the same axial position in the circumferential direction Ur. Here, the first latching recess 221 merges seamlessly into the second latching recess 222. The two latching recesses 221, 222 are preferably formed substantially identically, on the one hand from the mutual overlap of the latching recesses 221, 222, and in the circumferential direction Ur from the access to the first latching recess 221 for the latching protrusion 310.

[0060] In the present case, the latching projection 310 is formed in the manner of a mushroom, and the latching recesses 221, 222 are formed as caps similar to the mushroom-shaped latching projection 310, which in the present case are formed oval or circular. Of course, other forms of latching projections 310 and latching recesses 221, 222 that are at least partially complementary to each other can be used. In the possible mounting state M (two in the present case), the latching projection 310 is substantially completely filled in the corresponding latching recess 221, 222, again except for the above-mentioned access opening.

[0061] Figures 3 to 19 The coaxial connection device 1 ( Fig.13 ) of the electrical coaxial cable 50 when used on the electrical ring 20 of the second variant embodiment; of course, the second variation can be used on another cable, such as a twinaxial cable 50 (see Figure 1 and Figure 2 ), etc. Here, Figures 3 to 6 The collar 20 is shown in its open state O, Figures 7 to 10 The collar 20 is shown in its crimped mounted state M, and Figures 11 to 14 The collar 20 is shown in its over-crimped and compressed installed state kM. Figures 15 to 19 Further embodiments of the invention are shown.

[0062] That is, the ferrule 20 is preferably formed as a crimping ferrule 20, which is first crimped onto the cable 50. After this, possibly after turning over the free end portion of the outer conductor 53 of the cable 50 onto it, the shielding contact sleeve 40 is crimped onto the cable 50 and the ferrule 20. That is, during the mounting of the connection device 1 on the cable 50, the ferrule 20 is first crimped itself and then over-crimped with the shielding contact sleeve 40. First (mounted state M), the ferrule 20 on the cable 50 has a relatively (see below) large mounting diameter Md. After over-crimping (compressed mounting state kM), the ferrule 20 has a relatively (see above) small compressed mounting diameter kD, because the ferrule 20 has been compressed in the radial direction Rr by over-crimping.

[0063] In order to enable the collar 20 to be mounted on the cable 50 on the one hand (mounted state M) and to be compressed on the cable 50 in a radial direction Rr on the other hand (compressed mounted state kM), the collar 20 has a single self-locking 300, which also acts only in a single circumferential direction Ur, specifically for the opening of the collar in the direction of the open state O. That is, in the mounted state M, the collar 20 is fixed on the cable 50, its mounted diameter Md is not substantially increased, but the collar 20 is formed such that, on the cable 50, it can be radially reduced for the compressed mounted state kM and the compressed mounted diameter kD therein can be accepted to be smaller.

[0064] To this end, the first side portion 21 comprises a latching member 310, which is in particular formed as an outer hook 310 extending from the collar 20 in the radial direction Rr. In addition, to this end, the second side portion 22 comprises a latching member 320, which is in particular formed as an inner hook 320 protruding into the collar 20 in the radial direction Rr. In order that the latching members 310, 320 can be locked on one side, the collar 20 is formed or can be formed in a double-layered manner in the circumferential portion in the mounted state M and of course also in the compressed mounted state kM (pre-mounted state V).

[0065] The outer hook 310 can be formed as a circumferential lug 310, which extends tangentially and radially outwards from the bending plane of the first side portion 21. The inner hook 320 can be formed as a radial hook, which extends tangentially and radially outwards from the bending plane of the second side portion 22. In the mounted state M, the two circumferential sides of the outer hook 310 and the inner hook 320, which correspond to each other, are preferably in a more or less form-fitting manner (tolerance) (see Figure 8 and Fig. 9 ) abut against each other, wherein the plane thus formed is preferably not tangential to the collar 20 on the one hand, and on the other hand does not pass through the center of the collar 20. The plane cuts out a flat section from the cross section of the collar 20 or cuts out a flat cylindrical portion from the collar 20.

[0066] In the mounting state M and in the direction of the compressed mounting state kM, in the circumferential direction Ur, the inherent flywheel 301 is arranged in the collar 20 between the side parts 21, 22. Starting from the mounting state M, the side parts 21, 22 can firstly be displaced only in the circumferential direction Ur, in particular in the direction of the compressed mounting state kM. Beyond the mounting state M in the circumferential direction Ur and preferably before the compressed mounting state kM, it is to be arranged that in the circumferential direction Ur, the side parts 21, 22 can be moved relative to each other in the direction of the compressed mounting state kM and in the direction of the mounting state M. Here, the inherent flywheel 301 is particularly arranged as a sliding bearing or a circumferential sliding bearing, which extends in the circumferential direction Ur between the side parts 21, 22.

[0067] In addition, the collar 20 may have at least one impedance compensating member 308, 318, 328 (in particular at least one, for example rectangular, channel 308, 318, 328, as an air gap, air cushion, etc.) in one side 21, in both side portions 21, 22 and / or in the circumferential center portion 23. In the present case, three such impedance compensating members 308, 318, 328 are provided in the collar 20, regularly distributed in the circumferential direction Ur.

[0068] Here, the impedance compensating member 308 of the circumferential center portion 23 may cover a larger circumferential portion than the corresponding impedance compensating members 318, 328 in the side portions 21, 22. Preferably, the surface area of ​​the impedance compensating member 308 of the circumferential center portion 23 is substantially equal to the surface area of ​​the impedance compensating members 318, 328 of the side portions 21, 22 together, or, due to the inherent coverage of the collar 20 in the area of ​​the side portions 21, 22 in the circumferential direction Ur, is slightly smaller, perhaps by an amount of about 1 / 400 Å.

[0069] In the open state O and in the circumferential direction Ur, the outer axial edge of the impedance compensating member 318 of the first side portion 21 is preferably formed as a radially outer hook 310, that is to say a latching member 310. Similarly, in the open state O and in the circumferential direction Ur, the outer edge of the impedance compensating member 328 of the second side portion 21 is preferably formed as a radially inner hook 320, that is to say a latching member 320. In addition, axially before and / or after the impedance compensating members 308, 318, 328, that is to say along the corresponding impedance compensating member 308, 318, 328, the collar 20 may each include a reinforcing bead 304 running in the circumferential direction Ur.

[0070] In addition, the collar 20 may have at least one fixing hook 306 protruding inwardly in the radial direction Rr. Preferably, such a fixing hook 306 is arranged in the circumferential center portion 23. In addition, such a fixing hook 306 is preferably arranged in a corner portion of the impedance compensation member 308 of the circumferential center portion 23. In particular, two or four such fixing hooks 306 are arranged in a corner portion of the impedance compensation member 308 of the circumferential center portion 23. Of course, other positions can be used, in particular on / in one or both axial outer edges of the collar 20.

[0071] According to the invention, the collar 20 can be formed as non-crimpable, i.e. not as an elastically deformable collar 20, but as a spring collar 20 which is preferably only elastically and / or partially plastically deformable. That is, the two sides 21, 22 are arranged as spring sides 21, 22 relative to each other in the collar 20 in the circumferential center portion 23 in the radial direction Rr. Here, the collar 20 can also be processed during crimping and can therefore also be referred to as a crimping collar 20. This can be achieved in two variants of the invention. In addition, a hybrid between a crimpable collar 20 (see above) and a spring collar 20 can also be used.

[0072] Figures 15 to 19 Three further embodiments are shown. Here, in contrast to the above, the collar 20 in its open state O has a cross section which is a pot-shaped or u-shaped cross section (rounded rectangle open on one side). In the mounted state M (see Fig.19 ), the collar 20 can also be formed as above to be substantially circular, elliptical or oval. In addition, the collar 20 comprises at least one, in particular two, reinforcing beads 304 running in the circumferential direction Ur between the impedance compensation members 308, 318; 308, 328. These reinforcing beads 304 can be used in addition or alternatively in the above case, and in addition, the above reinforcing beads 304 can be used in addition or alternatively in these three other embodiments.

[0073] in addition, Figures 15 to 19 The collar 20 in the embodiment includes, on only one side 22, an anti-collision lug 322 protruding outward in the circumferential direction Ur for preventing the free circumferential ends of the side portions 21, 22 from colliding with each other during crimping of the collar 20. Here, the anti-collision lug 322 may be formed to be relatively narrow ( Fig.15 ) or relatively wide ( Fig.16 ) of the circumferential side 22, which may be advantageous, depending on the design of the collar 20 and / or the crimping process to be used. It is preferred here that the anti-collision lugs 322 are provided on the side 22, on which the inwardly directed latching members 320 are also formed.

[0074] In the open state O of the collar 20, the anti-collision lug 322 (see Fig.17 ) extends from the circumferential end of the side portion 22 in the circumferential direction Ur and possibly in the radial direction Rr. In the present case, in the open state O, the anti-collision lug 322 first extends substantially outwards in the radial direction Rr and then substantially in the circumferential direction Ur; of course mixed forms thereof can be used. And, in addition, in the mounted state M, the anti-collision lug 322 in the present case extends in the opposite way, specifically, first substantially in the circumferential direction Ur and then substantially inwards in the radial direction Rr. Here, the radial part of the anti-collision lug 322 is located in the circumferential direction Ur, wherein the circumferential part of the anti-collision lug 322 is curved radially inwards. Of course, other configurations of the anti-collision lug 322, such as ramps, etc., can also be used.

[0075] During crimping of the ferrule 20 (see Fig.18 ), the anti-collision lug 322 is actuated or triggered by a crimping tool, in particular a crimping indenter, so that the anti-collision lug 322 presses the first side portion 21 radially under the second side portion 22, thereby starting the freewheel 301 of the collar 20 in the direction Ur, so that the self-locking 300 ( Fig.19 Here, it is preferred that the crimping process works so that, and / or the anti-collision lug 322 is formed so that, in the installed state M of the collar 20, the anti-collision lug 322 has been swung into the corresponding impedance compensation member 318. In addition, Fig.18 The collar 20 is shown without the fixing hook 306 , which can be used likewise in the case of all embodiments.

[0076] In addition, the collar 20 can be formed such that the self-locking of the collar 20 is or can be provided by means of the anti-collision lug 322 and by a corresponding component (e.g., a component partially complementary thereto) of the collar 20. Here, for example, the anti-collision lug 322 can be formed such that it is locked in the installation state M and / or the compressed installation state kM, for example for larger cable diameters, using a latching component of the side 21, the latching component 310 or on / in the impedance compensation component 318. In particular, in such an embodiment, the anti-collision lug 322 can be locked in the compressed installation state kM by the side 21.

[0077] By means of the self-locking 201, 202; 300, springback of the ferrule 20 (preferably made of stainless steel) or the side parts 21, 22 during cable installation is compensated or prevented. According to the invention, the ferrule 20 does not have any stub crimping wings designed to abut against each other in the circumferential direction Ur to assume the function of a "support sleeve", because the ferrule 20 is designed for different cable types or cable sizes. It is preferred that the material thickness of the ferrule 20 is reduced by about 20% to 35%, in particular by about 30%, relative to a comparable conventional ferrule, in order to compensate for the material overlap in the flywheel 310. The material overlap also prevents the braided strands from being pulled into the crimping seam of the ferrule 20 during the production of the preassembled cable. The material of the ferrule 20 preferably has a (very) high tensile strength to assume the function as a "support sleeve".

[0078] The invention makes it possible to adapt different cable sizes (see above) or cable types (see above) to, for example, existing shielded contact sleeves. With these different cables, conventional collar designs cannot always close and therefore pre-assembly to the end product cannot be guaranteed. The collar 20 according to the invention can be crimped on such cable diameters (reaching from small, in particular smaller). Since the crimping diameter or crimping height (e.g. of the shielded contact cable to be installed later) determines the electrical properties of the end product, for example ensuring a good fit of the contact chamber in the housing, it is possible to pre-assemble the cable to a functional end product. The invention makes it possible to process, in particular crimp, cables of a range of diameters with identical component parts, that is to say not only one specific cable size and / or one specific cable type.
