Description

Technical Field

[0001] The invention relates to a method for crimping installation of an electrical HF crimp connection device of the same type at / on a cable type selectable from at least two types. The invention also relates to an electrical HF connector and an electrical HF entity, respectively, preferably for use in the automotive industry. 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.

[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 partially complementary connectors (connector and mating connector) usually have locking means and / or fastening means, which are used to lock and / or fasten the connector on / in the mating connector in a permanent but usually detachable manner, and vice versa. In addition, the electrical connection device for the connector, for example comprising or at least having: the actual contact member (terminal; usually formed as a single piece of material or formed integrally, such as (crimping) contact elements, etc.) or the contact device (terminal; usually formed as one part and a plurality of parts or two parts, or formed as a single piece of material, such as (crimping) contact devices) must be firmly held therein.

[0006] The connection device itself can be formed in multiple parts. Here, the connection device can, for example, include or have two or more terminals. This is the case, for example, of a coaxial or biaxial connection device, which can include or have one or two internal electrical terminals (male and / or female) and an external terminal (shielding contact sleeve). In addition, a collar (support sleeve) can be built into the external terminal in the connection device. In the case of (already) preassembled cables, such a connection device can be arranged as a connector (see above), that is to say without a housing, for example in the manner of flying leads.

[0007] There is a constant effort to improve electrical connectors and their connection devices, in particular to make them more robust, to design them more efficiently and to produce them at a lower cost due to miniaturization. For HF connection devices (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 that do not apply to conventional connection devices (defined here as: transmission frequencies below about 3 MHz), because the fluctuation characteristics of electricity in particular are evident in HF technology. In the case of electrical HF plug connections, maintaining signal integrity has proven to be an even greater obstacle.

[0008] In the case of HF connectors for HF plug connections, the signal integrity must be ensured by at least adequate impedance characteristics of the HF connector interacting with the partially complementary HF connector. Since the impedance along the signal path in the HF connector varies with the geometry or cross-section, and in order to obtain the required impedance over the length of the HF connector, the HF connector must be formed and processed accordingly, e.g. crimping installation at / on the cable must be ensured accordingly. It is therefore an object of the present invention to provide a method for crimping installation of an electrical HF crimp connector at / on a cable. Summary of the invention

[0009] The objects of the invention are achieved by universal crimping mounting of an electrical HF crimp connection device of the same type at / on a cable type selected from at least two types, by means of an electrical HF connector, preferably for the automotive industry, and an electrical HF entity, likewise preferably for the automotive industry. Advantageous developments, additional features and / or advantages of the invention follow from the dependent claims and the following description.

[0010] In addition to the different diameters of the two different types of cables (see below), the varying cable diameters are problematic during the pre-assembly process of the cables. This is for example because of at least one mechanical property (composition; hardness, compressibility, elasticity, elastic recovery, etc.) of the cable, in particular due to its relatively large dielectricity. Furthermore, this is made more difficult because cables of the same diameter from different manufacturers have different properties, in particular with regard to the insulation layer. Furthermore, there are the tolerance issues involved.

[0011] In the case of the method according to the invention, the optional crimping dimensions of the crimping tool used for crimping installation are selected according to the selected type of cable so that, for the installed state of the connecting device at / on the selected type of cable, the impedance of the at least partially preassembled cable is essentially set in the target corridor, for example essentially in the critical section or for the critical section by the selected crimping dimensions. That is, according to the invention, the tolerance-influenced impedance distribution of the connecting device at / on the selected type of cable is influenced, selected or established at least partially over its length. According to the invention, the critical section within the connecting device can be arranged radially below the corresponding crimp in the axial direction or offset therefrom in the axial direction; such a hybrid form is of course also possible.

[0012] In addition to the composition, i.e. the characteristics of the type of connection device, and the composition, i.e. the characteristics of the selected cable type, the crimping dimensions relate to, for example, the format of the crimping cross section of the connection device, and also, for example, the crimping diameter (ellipse, circle), the crimping radius (ellipse), the crimping section, the crimping area, etc. Here, the connection device (see above) can be formed, for example, as a contact member, a contact device or even a plurality of parts, for example three parts as a coaxial connection device, four parts as a biaxial connection device (two terminals), etc. In addition, the at least two types of cables that can be distinguished from each other can be formed as at least two of the following types: single-core or multi-core cable, coaxial cable, biaxial cable, triaxial cable, data transmission line, etc.

[0013] Here, a type is defined as follows: A specific or single or identical type naturally preferably has substantially identical or identical properties within the relevant tolerances, in particular within the relevant manufacturing tolerances, in particular in a plurality of individuals (tokens). This relates, for example, to all individuals of at least one batch of this type. Waste products (rejects) are of course excluded here. The single meaning (same meaning) of type or similar terms is, for example, model.

[0014] Identical or identical properties mean that for all individuals of at least one batch of (possibly multi-part) connection devices of the same type, they have the same form or the same dimensions etc. after manufacture and / or in the delivery state, of course within the tolerances involved. That is, all connection devices of at least one batch for one embodiment of the method originate from the same set of specifications, in particular the same original product drawing and / or product specification. That is, according to the invention, a specific individual connection device can be correctly mounted on at least two cables within the range of the product specifications of at least two different types of cables.

[0015] Identical or identical characteristics mean that all the individual cables of at least one batch of a specific or single or identical type have the same construction or the same diameter, radius, section, area, etc., after their manufacture and / or in the delivery state, of course within the tolerances involved. That is, all the cables of at least one batch of the same type used in the embodiment of the method originate from the same set of specifications, in particular the same original product drawing and / or product specification.

[0016] Here, the same properties also include, in particular, elasticity, elastic recovery behavior after crimping, etc. The length of the cable is of course not included here, since this depends on the customer's specifications; in particular, since the cable is usually supplied to this method as an endless cable.

[0017] The term "at least two types of cables (distinguishable from each other, i.e. not single or identical)" relates to at least two types of cables, for example from two manufacturers, for the same intended use or for similar intended uses. For example, there are two types of cables, one from The coaxial cable 3023" (RTK031), on the other hand, is from Gebauer & of" 5044 / 1" (RTK044 type (different specifications)), which also has two embodiments, one with a shielding film and one without a shielding film. The first has a softer dielectric than the second, and the second has a larger outer diameter than the first in the area of ​​the shielded conductor or protective sheath. That is, these "at least two types of cables" have the same intended use as coaxial data cables for vehicle communication applications, and differ in at least two characteristics.

[0018] This must take into account the installation conditions of the three-part coaxial connection device at / on the selected type of cable, such as ' 3023' or ' 5044 / 1'. That is, the impedance of the resulting, at least partially preassembled cable must be set substantially in the target corridor by the selected crimping dimensions, that is to say the later configuration of the crimping parts involved of the three-part coaxial connection device, so that the later preassembled cable can meet the high requirements of the automotive industry.

[0019] The crimping installation of the connection device at / on a cable of the corresponding type can be carried out in a single crimping machine (contact member, see above), a single automatic crimping machine (contact device, see above) or a crimping installation (multi-part connection device, see above). Here, the crimping dimensions of the crimping machine, automatic crimping machine or crimping installation corresponding to the impedance target corridor are appropriately selected for the formed, at least partially preassembled cable. Of course, this crimping, for example crimping sleeves, can also be established manually.

[0020] The impedance to be set in the target corridor depends on a number of factors, which are in particular specified by the user, such as the customer, and the intended application of the connection device. Here, the return loss is such a factor. Thus, for example, a cable sample crimped with the connection device is tested with the aid of a time domain reflectometry measurement (TDR: Time Domain Reflectometry) and used to determine the distribution of the impedance of the sample cable as a function of time (t). The time is related to the length of the sample cable, wherein the crimping area can be identified in the impedance distribution and the corresponding impedance can therefore be read. This operation is repeated for each sample cable crimped with a different crimp size.

[0021] The crimp dimensions, such as the crimp height, which are associated with the desired impedance (Im), are determined according to the invention based on laboratory measurements of sample cables with different crimp dimensions. Thus, the distribution of the variation in impedance of a three-part coaxial cable, crimped separately on a cable (see below), can be determined in the region of its ferrule (see Fig.12 This can be well and comparably represented in a polyline diagram, for example. Here, the specific type ( Figure 1 : Cable Type 1, Figure 2 : Cable Type 2) and then the cables of the same type ( Figure 1 and Figure 2 ) pre-assembly, wherein the shielding contact sleeve of the coaxial connection device is already crimped with different crimping sizes, which again are related to the crimping size of the pre-assembled cable in the area of ​​its coaxial connection device. This is illustrated by the multiple lines in the corresponding multi-line diagram.

[0022] The crimping dimensions that can be selected for the crimping tool can be the crimping diameter, crimping height and / or crimping width of the preferably closed crimping tool. In addition, the crimping tool can use the crimping dimensions that can be additionally set in the closed crimping tool and / or in the closed state of the crimping tool. In this case, "height" is the direction in which the part tool (especially the crimping indenter) of the crimping tool is movable. "Width" is basically perpendicular to its arrangement. The crimping dimensions that can be additionally set can be set, for example, by at least one additional member or device on / in the crimping indenter and / or the crimping anvil, which establishes a secondary dimension that exceeds the main dimension for crimping. This allows crimping of different forms or diameters to be established according to the form of the open / closed crimping tool. In the case of a cable whose conductor also has a coaxial arrangement, these are generally substantially circular, substantially elliptical or substantially oval crimping cross-sections of the connecting device.

[0023] The crimping dimensions of the crimping tool can also be selected depending on the composition of the connection, in particular the geometry, cross-section and / or material distribution. Thus, for example, a reduction in impedance can be achieved by reducing the inductive component or by increasing the capacitive component of the connection, or vice versa. The material of the dielectric of the connection and the air gap in the connection influence the capacitance of the connection, since the dielectric constant of the dielectric and / or air is related to the corresponding capacitance of the connection, wherein the higher the dielectric constant, the lower the impedance.

[0024] In addition, the crimping size of the crimping tool can be selected based on the temporally anterior crimping size of the crimping of the connection device. The crimping size is of course again related to the crimping size of the corresponding crimping tool. In addition, the crimping size of the crimping tool can be selected based on the subsequent use conditions and / or requirements of the overall connection device and / or preassembled cable.

[0025] In the case of a connection device to be crimped several times, the method can be designed so that the impedance is substantially set in the target corridor by the final crimping step. Such a connection device to be crimped several times can, for example, be formed as a coaxial connection device or a biaxial connection device (see below). The crimping size of the crimping or the crimping dimensions before crimping can be a global fixed setting of the method, that is, the same setting for all types of cables, or a corresponding specific setting for a selected type of cable.

[0026] The target corridor may be characterized by a minimum, average and / or maximum impedance and / or a very critical portion of the connection device. In the case of a 50Ω coaxial cable, the minimum or average impedance of the preassembled cable in the area of ​​its connection device may be, for example, about: 44Ω, 45Ω, 46Ω, 47Ω, 48Ω or 49Ω. Of course, other cable impedances may be used, such as 75Ω, 93Ω to 125Ω, etc. Here, the impedance may have the following tolerances: ±0.05Ω; ±0.1Ω; ±0.15Ω; ±0.2Ω; ±0.25Ω; ±0.3Ω; ±0.4Ω; ±0.5Ω; ±0.75Ω, ±1Ω or ±1.5Ω. Of course, other impedances may be used, such as 75Ω, 93-125Ω, etc.

[0027] In the case according to the invention, the connection device can have at least one electrical HF crimping terminal, an electrical component different therefrom and / or an electrical device different therefrom. For the installed state of the connection device at / on a cable of the selected type, the impedance of the at least partially preassembled cable can be substantially set in a target corridor within its connection device by the selected crimping dimensions of the crimping tool for the terminal, component and / or device.

[0028] In the case of the method according to the invention, the connection device can have an outer electrical HF crimping shielding contact sleeve, an optional electrical HF crimping ferrule and at least one inner electrical HF crimping terminal. For the installed state of the connection device at / on a cable of the selected type, the impedance of the at least partially preassembled cable can be substantially set in a target corridor within its connection device by the selected crimping dimensions of the crimping tool for the shielding contact sleeve.

[0029] Depending on the configuration of the same type of connection device, in addition to at least two possible types of cables, the method according to the invention is only applicable to a single type of shielding contact sleeve, a single type of ferrule, a single type of terminal (pin / coupling / tab / socket terminal), a single type of electrical component, a single type of electrical device and / or the like. Here, the connection device can be formed, for example, as a coaxial or biaxial connection device.

[0030] In a first crimping step of the method, the ferrule can be crimped onto the shielded conductor of the cable. Before a second crimping step of the method, the radial end portion of the shielded conductor can be placed radially outside the ferrule. After the first crimping step / the second crimping step, the internal terminal can be crimped onto the internal conductor of the cable. In a third crimping step of the method after the second crimping arrangement, the shielded contact sleeve can be crimped onto the shielded conductor and the protective sleeve of the cable. If the crimping ferrule is not present in the connection device, of course the first crimping step is omitted, and the second crimping step becomes the first crimping step, and similarly, the third step becomes the second step.

[0031] In the first crimping step, the cable can be placed in the ferrule without a portion of the cable's one / said protective sleeve and / or vice versa. It is preferred here that the protective sleeve is partially pulled off. In addition, during its crimping installation on the shielded conductor, the ferrule can be deformed only elastically, partially plastically or substantially plastically. In addition, the first circumferential side portion can be placed on the second circumferential side portion of the ferrule in the radial direction of the cable or the ferrule. In addition, the ferrule can be held on the cable in the axial direction of the cable by at least one fixing hook formed thereon (e.g., puncture). And preferably, between the circumferential side portions superimposed on each other in the radial direction, a self-locking of the ferrule can be established in the circumferential direction of the cable or the ferrule.

[0032] Preferably, the collar in its open position has circumferential side portions which extend in the axial direction of the cable or of the collar, are opposite to each other in the radial direction and are connected to each other in the circumferential direction of the cable via a circumferential center portion. The self-locking of the collar in the circumferential direction is established by the circumferential side portions, with the effect that the collar can variably form a mounting diameter for its mounted state on the cable. In the self-locking, preferably two free radial end portions of the circumferential side portions engage each other in the circumferential direction.

[0033] The setting of a specific installation diameter of the ferrule on the cable is firstly carried out by a (single) self-locking of the ferrule 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, a single self-locking can comprise a plurality of individual lockings. In the self-locking, the latching members of the first circumferential side can be formed as radially outer hooks, while the latching members of the second circumferential side can be formed as radially inner hooks.

[0034] After the first crimping step, a self-locking is established by the collar, by which the substantially maximum installation diameter of the collar in its installed state is established on the cable. The self-locking can be effective in the collar, so that the maximum installation diameter of the collar does not increase again and / or the maximum installation diameter can nevertheless be reduced. In the installed state, an inherent flywheel (gap) is established in the collar between the circumferential side parts, wherein the circumferential side parts are established so that they can be displaced relative to each other, preferably initially only in one circumferential direction. The inherent flywheel is preferably established as a (circumferential) sliding bearing (not a radial sliding bearing with a rotating bearing partner), which extends in the circumferential direction between the circumferential side parts.

[0035] The collar may have an anti-collision lug protruding outwardly in the circumferential direction on only one circumferential side. The anti-collision lug is used to prevent the free circumferential ends of the circumferential side from colliding with each other during the crimping of the collar. Therefore, in the first crimping step, the second circumferential side can be radially pressed under the first circumferential side by the anti-collision lug. During the crimping of the collar, the anti-collision lug is actuated or triggered by a crimping tool, in particular a crimping indenter, so that the second circumferential side is radially pressed under the first circumferential side by the anti-collision lug. Over time, the flywheel of the collar in the circumferential direction begins, and the self-locking of the collar is then automatically established. Preferably, the crimping process works so that, in the installed state of the collar, the anti-collision lug swings into a recess, for example, in the barrel of the collar, in particular into a corresponding impedance compensation member (see below).

[0036] The collar can be formed as a substantially only elastic and / or partially plastically deformable, mechanically prestressed spring collar. Therefore, by means of the spring collar, the overturned radial end portion of the shielding conductor can be prestressedly supported on the outside of the spring collar. The collar can have an impedance compensation member in at least one circumferential side portion or in two circumferential side portions and / or in a circumferential center portion. The corresponding impedance compensation member is particularly established as a substantially rectangular channel (air gap, air cushion). Here, the impedance compensation member is formed and dimensioned so as to improve the impedance of the collar. Forming in this way helps to adjust the low impedance zone 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.

[0037] - / The edge of the impedance compensating member of the first circumferential side portion can be formed as a latching member of the first circumferential side portion. The latching member of the first circumferential side portion can be formed as a circumferential lug, which extends radially outward from the curved plane of the first circumferential side portion and may have a tangential portion. - / The edge of the impedance compensating member of the second circumferential side portion can be formed as a latching member of the second circumferential side portion. The latching member of the second circumferential side portion can also be formed as a radial hook, which extends radially inward from the curved plane of the second circumferential side portion and may have a tangential portion.

[0038] In the open state of the collar, the circumferential center portion can have a smaller radius of curvature than the circumferential portion of the circumferential side portion directly adjacent in the circumferential direction. This can certainly also be related to the circumferential side portion. As a result, the collar is given a cross section, which is a pot-shaped or u-shaped cross section in the front view, with a relatively straight or relatively (relative to the circumferential portion directly adjacent to the circumferential side portion) less curved transverse member between its two legs. In other embodiments, the collar can be formed in the form of an arc of a circle or an elliptical arc in the cross section or the front view. Of course, an oval arc ring portion can also be used. The circumferential side portion can be formed as a substantially straight line or slightly inwardly curved in its side circumferential center portion. That is, for example, 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.

[0039] In particular, the reinforcing beads are built on the axial end portions or, preferably, the reinforcing beads formed as elongated reinforcing beads are built in both axial end portions. It is preferred here that the corresponding reinforcing beads extend from the circumferential side portions on the circumferential center portion and through the impedance compensation member of the circumferential center portion into the other circumferential side portions, wherein the two longitudinal ends of the reinforcing beads are located in the circumferential side portions. In particular, it is preferred that the collar is formed for its intended user such that one circumferential end of such a reinforcing bead does not come into mechanical contact with the corresponding circumferential end of the circumferential side portions in the compressed or pressed together installed state of the collar (discontinuous diameter reduction).

[0040] In addition, the circumferential transition region from the circumferential center part into the circumferential 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 circumferential side part. Here, at least one, in particular two or more such reinforcing beads can be established 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 fluidically connected via at least one reinforcing bead.

[0041] In the third crimping step, a crimping dimension of the crimping tool can be selected for the shield contact sleeve, at least in a portion of the shield contact sleeve above the ferrule. In addition, in the third crimping step, the installation diameter of the ferrule on the cable and in the shield contact sleeve can be reduced to achieve an impedance in a target corridor. In addition, in the third crimping step, the self-locking of the ferrule can be automatically released and the circumferential side portions can slide past each other in the inherent freewheel.

[0042] After the third crimping step, the self-locking of the ferrule can be disengaged. Here, the crimping size of the crimping tool is of course again related to the crimping size of the crimping of the shield contact sleeve. In this case, the turned radial end portion of the shield conductor can be pressed radially outward by the compressed radial portion of the ferrule and / or the cable and is held radially outward by the shield contact sleeve. As a result, a good electrical contact of the shield conductor with the shield contact sleeve is ensured.

[0043] The HF connector according to the invention has a connector housing and a connection device, wherein the connection device is installed on the cable by the method according to the invention. Here, the HF connector can be formed as a coaxial connector, a biaxial connector, etc. The HF entity according to the invention has a connector or an electrical connection device, wherein the connector is formed as an HF connector according to the invention, or the connection device is installed on the cable by the method according to the invention. Here, the entity can, for example, in addition to the entity housing, also have at least one mechanical, electrical, electronic, optical and / or fluid component or device. Such an entity can, for example (also) be formed as a component, device, preassembled cable, subassembly, circuit board, component, module, facility, equipment, unit, installation, system, etc.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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. It is thus possible to separate a feature (possibly including its periphery) 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.

Two cables 50 Tn The inner conductor 51, dielectric 52, shielding members 53, 54 and protective cover 55 are respectively included from the inside to the outside. In this case, the shielding members 53, 54 are divided into a shielding film 53 and a shielding conductor 54 arranged thereon. T3 Cable 50 Tn In the case of, for example, the shielding film 53 can be omitted. T1 , 50 T2 , 50 T3 , ..., cable 50 Tn With different characteristics (see above), it is in cable type 50 T1 , 50 T2 , 50 T3 This must be taken into account during assembly with various types of (prior art) HF crimp coaxial connectors and in particular with HF crimp coaxial connectors 1 of the same type (invention) in order not to impair too much the signal integrity of the (partially) preassembled cable 50 thus formed (see above).

[0055] In the invention, a connection device 1 of the same type is crimped and installed on a cable type 50 which can be selected from at least two types. Tn ; 50 T1 , 50 T2 , 50 T3 In the case of the method according to the invention, in the first step (by Figure 1 and Figure 8 The example shown in FIG. 1 shows an example of an electrical HF crimping ferrule 20 being crimped onto a selected type of cable 50. T1 / 50 T2 / 50 T3 / ... on the shielded conductor 54 (first crimping step I of the connection device 1). Possible embodiments of the ferrule 20 are as follows: Figures 3 to 6 In order to enable the connecting device 1 to be crimped on various types of cables 50 Tn ; 50 T1 , 50 T2 , 50 T3 , ..., the collar 20 is formed so that, from the selected type of cable 50 T1 / 50 T2 / 50 T3 Mounting status M on / ... 20 Starting from the initial form, the overall connection device 1 is connected to the cable 50 T1 / 50 T2 / 50 T3 Mounting status M on / ... 1 It can be radially compressed or reduced, for which purpose the collar 20 is preferably formed in a double-layered manner in the circumferential portion.

[0056] In the second step, following the first step (by Figures 9 to 11 The example shown in FIG. 1 shows an example of an internal electrical HF crimp terminal 10 being crimped onto a selected type of cable 50. T1 / 50 T2 / 50 T3 / ... on the inner conductor 51 (the second crimping step II of the connecting device 1). In the third step, following the second step (by Fig.12 ), an external electrical HF crimp terminal 40, in particular a HF crimp shielding contact sleeve 40, is crimped over the ferrule 20 and a cable 50 of the selected type. T1 / 50 T2 / 50 T3 / ... on the protective sleeve 55 (third crimping step III of the connecting device 1, the installation state M of the connecting device 1 1 ). Due to its design, the diameter of the collar 20 can be compressed or reduced for this purpose (see above).

[0057] During the preassembly process, in a first step, the corresponding cable 50 is preferably first assembled. Tn , 50 T1 / 50 T2 / 50 T3 The protective sleeve 55 of the / ... is partially pulled off, wherein its shield conductor 54 is exposed. Of course, it can also be pulled off completely. Afterwards, the collar 20 is crimped onto this free longitudinal portion (first crimping step I), wherein the collar 20 is essentially only elastically (preferably), partially plastically (preferably) and / or essentially plastically deformed. In this case, the collar 20 comprises (see Figures 3 to 7 ) a circumferential center portion 23 and two circumferential side portions 21 , 22 , each having a free circumferential end (see also above).

[0058] In the case of the collar 20, from its open state O 20 Start (see Figure 3 and Figure 4 ), the two circumferential side portions 21, 22 can be bent toward each other, wherein in the installed state O 20 The self-locking 200 of the two circumferential side portions 21, 22 is established during the crimping (see above). Here, the collar 20 is formed and mounted on the cable 50 Tn , 50 T1 / 50 T2 / 50 T3 / ... so that a natural flywheel 201 is established in the collar 20, wherein, starting from the provision of the self-locking 200, the circumferential sides 21, 22 can be displaced relative to each other, preferably initially only in one circumferential direction Ur, see also above.

[0059] The circumferential side portions 21, 22 can have latching members 210, 220, respectively, for the self-locking 200 of the collar 20, wherein the self-locking 200 is in the state M of the collar 20. 20 In addition, the latching members 210, 220 may be effective only for an increase in the installation diameter of the collar 20. In addition, the latching members 210, 220 may allow a reduction in the installation diameter of the collar 20. That is, the latching members 210, 220 constitute members that stop the mutual displaceability of the circumferential side portions 21, 22 in the circumferential direction Ur, so that the displaceability of the circumferential side portions 21, 22 in the direction of the reduction of the installation diameter of the collar 20 is still possible.

[0060] The latching member 210 of the first circumferential side portion 21 may be formed as a radially outer hook 210, and the latching member 220 of the second circumferential side portion 22 may be formed as a radially inner hook 220. That is, the outer hook 210 is formed as a latching hook 210 extending radially outward from the first circumferential side portion 21, and the inner hook 220 is formed as a latching hook 220 extending radially inward from the second circumferential side portion 22. 20 to its compressed installation state (M 1 ), the latch members 210, 220 release each other during the initial transition of the shield contact sleeve 40. The compressed mounting state (M) of the collar 20 may be used, for example, when the shield contact sleeve 40 is crimped over the collar 20. 1 ).

[0061] In addition, the collar 20 can preferably have a single impedance compensation member 208 and / or at least one reinforcement bead 204 in its circumferential center portion 23. In addition, the collar 20 can preferably have a single impedance compensation member 218, 228 and / or at least one reinforcement bead 204 on its two circumferential side portions 21, 22, respectively. In particular, in the circumferential center portion 23, at least one fixing hook 206 can be established in the collar 20, which protrudes inwardly in the radial direction Rr. Here, in particular, a plurality of fixing hooks (two or four) can be arranged in the corner regions of the impedance compensation member 208 of the circumferential center portion 23. It is also possible to omit the fixing hook 206 ( Figure 5 ), see also above.

[0062] In addition, the collar 20 may include an outwardly protruding anti-collision lug 222 on only one circumferential side portion 22 for preventing the free circumferential ends of the circumferential side portions 21, 22 from colliding with each other during crimping of the collar 20 ( Figure 4 and Figure 5 Here, the anti-collision lug 222 may be formed to be relatively narrow in the axial direction Ar ( Figure 5 ) or relatively wide ( Figure 4 ) 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 lug 222 is provided on the circumferential side 22 (the second circumferential side 22), on which the inwardly directed latching member 220 is also formed.

[0063] In the open state O of the collar 20 20 In the open state O, the impact lug 222 extends from the circumferential end of the circumferential side portion 22 in the circumferential direction Ur and possibly in the radial direction Rr. 20In the embodiment of the present invention, the anti-collision lug 222 first extends substantially outward in the radial direction Rr and then substantially in the circumferential direction Ur; of course, mixed forms thereof may be used. And, in addition, in the mounted state M of the collar 20 20 In the embodiment of the present invention, the impact lug 222 extends in an opposite manner, in the present case specifically first substantially in the circumferential direction Ur and then substantially inwardly in the radial direction Rr. Here, the radial portion of the impact lug 222 is located in the circumferential direction Ur, wherein the circumferential portion of the impact lug 222 is bent radially inwardly. Of course, other configurations of the impact lug 222 can be used, such as ramps for sliding over or under one circumferential side over / under another, etc.

[0064] During crimping of the ferrule 20 (see Figure 5 ), the anti-collision lug 222 is actuated or triggered by a crimping tool, in particular a crimping indenter, so that the anti-collision lug 222 presses the first circumferential side portion 21 radially under the second circumferential side portion 22, thereby starting the freewheel 201 of the collar 20 in the circumferential direction Ur, so that a self-locking 200 of the collar 20 can be provided. Here, it is preferred that the crimping process works so that, and / or the anti-collision lug 222 is formed so that, in the installed state M of the collar 20 20 , the anti-collision lugs 222 have been swung into the corresponding impedance compensation members 218 (see also below).

[0065] In the crimping ring 20 ( Figure 8 ) after which the possibly only partially pulled-off radial end portion of the protective sleeve 55 is completely removed. After this, the axial portion of the shielding conductor 54 protruding below the collar 20 in the direction of the free longitudinal end (preferably without the shielding film 53) is bent over the collar 20 ( Fig. 9 ). After this, the cable 50 Tn , 50 T1 / 50 T2 / 50 T3 / ... the remaining free radial end portion ( Figure 2 ) is prepared for crimping of the internal terminal 10. After this, the internal terminal 10 (electromechanical contact portion 11, electromechanical fastening portion 12 and electromechanical crimping portion 13) is crimped to the cable 50. Tn , 50 T1 / 50 T2 / 50 T3 / …on (Second crimping step II, Fig.11 ).

[0066] Finally, the shielding contact sleeve 40 (electromechanical contact portion 41, electromechanical fastening portion 42 and electromechanical contact portion 43) can be crimped onto the collar 20 and further back onto the protective sleeve 55 (third crimping step III). Tn , 50 T1 / 50 T2 / 50 T3 Mounting state M of the shielding contact sleeve 40 at / … 40 (=M 1 ), the impedance Im of the at least partially preassembled cable 50 is substantially set by the selected crimping dimensions in the target corridor Zi within its connection device 1. This is done, for example, on the basis of the above-mentioned sample cable, wherein crimping dimensions, such as crimping height (see above), are selected in relation to the desired impedance.

[0067] When the collar 20 is over-crimped by the shield contact sleeve 40, the collar 20 is automatically released and the circumferential side portions 21, 22 can slide past each other in the inherent flywheel 201. Here, the collar 20 is released from its mounted state M below the shield contact sleeve 40. 20 Move radially to its compressed mounting state (M 1 ). Therefore, the cable 50 T1 / 50 T2 / 50 T3 The mounting diameter of the collar 20 on the / ... is reduced to a compressed mounting diameter.

[0068] In addition, the collar 20 can be formed such that the self-locking of the collar 20 is established or can be established by means of the anti-collision lug 222 and by a corresponding component of the collar 20 (for example, a component partially complementary thereto). Here, for example, the anti-collision lug 222 can be formed so that it locks in the installed state M 20 and / or compressed installation status (M 1 ), for example for larger cable diameters, utilizing a latching member of the circumferential side portion 21, the latching member 210 or on / in the impedance compensation member 218. In particular, in such an embodiment, the anti-collision lug 222 can be locked in a compressed mounting state (M) by the side portion 21. 1 )Down.

[0069] Additionally, embodiments having an outer collar 20 with an inner collar 20 above it may also be used. T1 / 50 T2 / 50 T3 / … is partially stripped of its insulation in stages, preferably completely, at its radial end portions and is prepared. In the first crimping step of the method, the inner terminal 10 is crimped on. After this, the shield conductor 54 is opened and the shield contact sleeve 40 is fitted underneath it, wherein the shield contact sleeve 40 is installed with a slightly wider crimping gap, which must be further closed later. After this, the ferrule 20 is crimped onto the shield conductor 54 and the shield contact sleeve 40, wherein the at least partially preassembled cable 50 is formed T1 / 50 T2 / 50 T3 The impedance of / … is basically set in the target corridor Zi.
