SHIELDED ELECTRICAL CONNECTOR

Description

Field of the invention

[0001] The present disclosure relates to a shielded electrical connector and a method for manufacturing a shielded electrical connector. Background and general description of the invention

[0002] Methods for providing cables with shielding when connected to a connector are already known. For example, solutions are known that use a crimp sleeve and a union nut; see German patent DE 196 13 228 B4.

[0003] In another variant, for example in US 5,906,513, it is proposed to press a sleeve-shaped housing with tabs onto a metal braided shield of a cable and then to overmold it with a thermoplastic material.

[0004] From DE 10 2008 018 403 A1 a method is known in which a shield is used which consists of an electrically conductive plastic.

[0005] Document WO 2016 135 170 A1 from the applicant describes a process in which a shield is produced using a metal casting process. The present application can be viewed as a further development of the aforementioned patent application, which is why WO 2016 135 170 A1 is incorporated by reference.

[0006] In addition to the disadvantages of the previously mentioned prior art already mentioned in WO 2016 135 170 A1, the previously known methods for shielding connectors sometimes require complex assembly and can have different contact resistances at the contact zones of the shielding, particularly due to temperature and aging of the materials used.

[0007] Furthermore, all previously known methods only offer a connection of the outermost shielding sheath of the cable to the connector.

[0008] However, cables can be used according to the invention in which conductors arranged in the cable can or should have additional cable shielding. In order to reduce or prevent crosstalk of signals from the various conductors to other conductors, it can therefore even be advantageous or desirable if the conductor shielding, which shields individual conductors or a subset of the conductors of the cable from one another, can also achieve the shielding effect further or continuously in the area of ​​the connector, so that no crosstalk occurs between the conductors. This is not provided for or not possible in the previously known methods.

[0009] EP 3 352 311 A1 discloses a circular connector with a plurality of contact elements, in particular for establishing an Ethernet connection, and a method for its production. Spreading devices and an insulating body are used to accommodate the contact elements, based on the finding that the best and most cost-effective material for producing the insulating body is an insulating gas, in particular air.

[0010] The present invention is based on the object of creating a shielded electrical connector with a good shield connection between a shielded electrical cable and a shielded plug connector.

[0011] Another aspect of the task is to create a durable shielded electrical connector in which the contact resistance between the components involved in the shielding remains low throughout the service life of the connector.

[0012] The shielded electrical connector is therefore advantageously simple and largely machine-producible and particularly preferably has as few individual parts as possible in order to further simplify assembly.

[0013] A particular focus of the task is to connect shielded electrical cables with connectors in which individual or a subset of the conductors of the electrical cable have partial shielding or sub-shielding, so that this partial or sub-shielding can also develop its effect in the area of ​​the connector and, in particular, is also connected to the shielding.

[0014] The object of the invention is achieved by the subject matter of the independent claims. Advantageous developments of the invention are defined in the subclaims.

[0015] The shielded electrical connector comprises a plurality of line elements, i.e. at least two line elements that belong to a line or the plug-in connector. For example, the line elements are part of an electrical cable which are to be connected to contact elements of a plug-in connector. Typically, each line element has a line element sheath for electrically insulating the respective line element. The shielded electrical connector therefore comprises a plurality of line element sheaths, wherein each line element typically has its own line element sheath. The plurality of line element sheaths are therefore at least two line element sheaths. The line element sheaths can, for example, be a plastic sheath, rubber sheath, or any other type of wire insulation. A shrink tube orA cable element sheath subsequently applied during the assembly of the connector comes into consideration.

[0016] Furthermore, an outer shielding sheath is included, which at least partially or at least regionally surrounds the plurality of line elements. Typically, the outer shielding sheath completely surrounds the line elements in the region of the unopened cable, i.e. continuously from a first end of the cable to a second end of the cable. By means of the outer shielding sheath, a shielding effect can therefore be achieved along the entire cable, wherein in a preferred embodiment the shielding sheath can also be grounded at at least one end of the cable to the connector(s), for example to a contact ring of a housing part. In other words, the outer shielding sheath encloses all line elements together, so that the line elements are arranged together on an inner side of the outer shielding sheath and are shielded from the environment by means of the outer shielding sheath.

[0017] In the area where the cable connects to the connector, the outer shielding sheath is exposed to access the conductor elements for contacting the contact elements. This exposure is preferably done mechanically, so that a consistent ring area of ​​the outer shielding sheath is exposed at each point, for example, at one end of the cable.

[0018] Furthermore, at least one inner shielding sheath is included, which surrounds a subset of the line elements together, at least partially or at least in regions, for shielding against remaining line elements. For example, the line elements can be grouped together in pairs and each pair can be provided with a respective inner shielding sheath. In one example, the cable comprises a total of eight line elements, each pair of which is surrounded by an inner shielding sheath, so that in this example four inner shielding sheaths are included, which are all once again surrounded by the outer shielding sheath. The subset of line elements comprises at least one line element, typically two line elements. The subsets can comprise a different number of line elements. It is preferred and provided that a line element is assigned to exactly one subset.In a cable comprising different conductor elements, it can then also be provided that only a subset of the conductor elements has the inner shielding, for example, to additionally shield current-carrying wires from signal-carrying wires in a shared cable. In a preferred case, a first subset of conductor elements, for example, signal-carrying, is enclosed by a first inner shielding sheath, and a second subset of conductor elements, for example, also signal-carrying, is separately enclosed by a second inner shielding sheath.

[0019] It also includes a connector housing in which the plurality of line elements can be contacted, in particular with contact elements. Typically, the connector housing also includes a mating face for connecting to another line part or for contacting the line elements with a subsequent assembly.

[0020] The shielded electrical connector further comprises a shield divider forming at least two shield sectors. For example, the shield divider has at least two shield bars, with the radial region between each of the shield bars forming one of the shield sectors. At least one conductor element can be routed through a shield sector. Preferably, one of the subsets of the conductor elements is routed through a shield sector, specifically a subset in which the individual conductor elements of this subset do not need to be shielded from each other, but only from the other conductor elements of the cable.

[0021] Furthermore, at least one sealing insert is included to seal a cable side in the region of the shield divider from a connector side. In other words, the sealing inserts are provided to create a fluid-tight barrier so that no fluid exchange can occur from the cable side to the connector side and / or vice versa. In other words, the sealing insert(s) provide a fluid barrier in the axial direction so that fluid exchange between the connector side and the cable side is prevented. The sealing inserts thus also ensure that no liquid material can penetrate from the cable side into the connector side and thus into the connector.

[0022] The line elements are either passed through the sealing inserts, or the sealing inserts are applied to the respective line element(s), e.g., by injection molding or molding. For example, several sealing inserts are provided for arrangement, insertion, injection molding, or casting into a shielding sector, in particular one sealing insert in each shielding sector.

[0023] Furthermore, an electrically conductive shielding bridge is included for electrically, in particular non-detachably, connecting the outer shielding sleeve to at least the inner shielding sleeve(s) and the shield divider. In other words, the electrically conductive shielding bridge or shielding insert provides an electrical bridge that connects the outer shielding sleeve to the inner shielding sleeves and the shield divider with the lowest possible electrical resistance.

[0024] The electrically conductive shielding insert or the electrically conductive shielding bridge can establish a non-detachable connection between the outer shielding sleeve, the inner shielding sleeves, and the shield divider up to the connector housing, wherein the electrically conductive shielding bridge is preferably arranged integrally around the conductor element sleeves. Particularly preferably, the electrically conductive shielding bridge can radially enclose the conductor element sleeves on all sides. This means that the electrically conductive shielding bridge is also arranged between the conductor elements. In other words, the shielding bridge also ensures through-connection of the inner shielding sleeves to the shield divider and the outer shielding sleeve, whereby the inner shielding effect or the intermediate conductor shielding is maintained, in particular completely and / or without gaps.In other words, the electrically conductive shielding bridge can provide an electrical shielding effect, in particular without gaps, from the cable via the open areas of the cable near the connector housing and through the shield divider to the connector housing, wherein the internal shielding effect between the subsets of line elements is also maintained, in particular without gaps.

[0025] If the line elements are each separately provided with line element sheaths, it is particularly advantageous if the electrically conductive shielding bridge is arranged between each line element, i.e., between all line elements. In other words, the electrically conductive shielding bridge radially surrounds each line element on all sides. If a subset of line elements has a common second line element sheath, for example in the form of a shrink tube, which is applied, for example, over a pair of line elements, then the electrically conductive shielding bridge likewise radially surrounds all line element sheaths, with the intermediate region between the pair of line elements possibly remaining free of the electrically conductive shielding bridge.In other words, the interior of the second conducting element sheath is not filled with the electrically conductive shielding bridge in this case, but rather is arranged around the respective second conducting element sheaths. In this case, too, the electrically conductive shielding bridge radially surrounds the pair of two conducting elements with a second conducting element sheath and thus also each conducting element on all sides.

[0026] In other words, a practical example is for each conductor element to have a separate conductor element sheath, in particular a wire insulation. The electrically conductive shielding bridge is then inserted such that the shielding bridge surrounds the conductor elements on all sides, in particular radially surrounds each individual conductor element, and thus preferably extends between the individual conductor elements. For example, in the liquid state, it flows between the conductor elements and is distributed there in such a way that a coherent component is produced as an electrically conductive shielding bridge. The conductor element sheaths are designed to withstand the thermal stress during insertion of the shielding bridge, so that no electrical contact occurs between the conductor elements and the shielding bridge.For example, the conductor element sheaths are designed not to melt when the electrically conductive shielding bridge is applied, so that no short circuit occurs between one of the conductor elements and the shielding bridge. An electrical connection between the conductor elements and the electrically conductive shielding bridge is therefore not provided or does not exist in the area in which the shielding bridge is used. If necessary, one of the conductor elements, in particular a ground connection, can be contacted with the shielding bridge in a special design in the plug; this is not intended to be ruled out. However, the preferred case is one in which there is no electrical contact between the conductor elements and the shielding bridge, but rather the shielding bridge provides electrical shielding between the conductor elements and also electrical shielding of the conductor elements from the environment.

[0027] The electrically conductive shielding bridge is thus arranged around the line elements and also between the line elements and forms a one-piece, i.e. monolithically constructed component as a shielding bridge. The one-piece, i.e. monolithically constructed electrically conductive shielding bridge, as a continuous component, directly connects the outer shielding sleeve with the inner shielding sleeve(s) and the shield divider. This creates a firm and secure electrical connection between the three aforementioned components: outer shielding sleeve, inner shielding sleeve(s), and shield divider. This connection can be provided in particular without gaps by means of the shielding bridge between and around the line elements. The secure contact between all of the aforementioned components can ensure a simplification of the manufacturing process, since the electrical contact may no longer need to be checked.The single-piece component of the shielding bridge, which electrically connects all of the aforementioned components, particularly in a solid and melting manner, may exhibit lower electrical resistance compared to a multi-part shield. A multi-part electrical shield may also require additional manufacturing steps. On the other hand, the seamless shielding of the shielding bridge can improve signal quality and / or reduce signal attenuation, particularly in high-frequency applications (i.e., in RF technology) and / or in applications where external interference fields are expected.

[0028] A special feature that can be realized with the shielding bridge of the present invention is that the outer shielding (in particular of the cable), the inner shielding(s) (in particular of two line elements each), and the shield divider are electrically connected to one another in a monolithic design. This avoids, reduces, or prevents potential defects in the shielding. In contrast to a potentially multi-part shielding bridge, there are no longer any "jumps" where a seamless connection depends, for example, on the bond strength to the intermediate part and the ability to provide a seamless shielding bridge in such a case. Thus, in the case of a multi-part shielding bridge, the various parts can possibly deviate from one another during use, for example in the event of vibrations during operation or in the event of an impact.They become separated from each other in such a way that only insufficient contact or a contact that interrupts the shielding effect can be established. These problems can be eliminated or improved with the monolithic shielding bridge presented here. The electrical contact between the three shielding elements (outer shield, inner shield(s), shield divider) is thus ensured or improved due to the monolithic structure of the shielding bridge, and at the same time, the most all-round and fully enclosing shielding of the line elements in the area in which the shielding bridge is arranged can be achieved.

[0029] It can also be provided that the conductor elements are stripped over a longer section, for example, in the axial direction out from the shielding sectors toward the cable, and a cover, such as an injected plastic, is first applied to the stripped ends of the conductor elements. The electrically conductive shielding insert can also be applied to this cover.

[0030] It is preferred that the conductor elements are only stripped up to the sealing elements, and that the conductor element sheaths remain intact in the area onto which the electrically conductive shielding bridge is cast, so that the shielding bridge is cast directly onto the conductor element sheaths, for example. This allows the material of the shielding bridge to also reach between the subsets of the conductor elements, preferably between the individual conductor elements.

[0031] With regard to the shielding effect, it may be irrelevant whether the conductor elements arranged together in a pair or subset are not shielded from one another by the electrically conductive shielding bridge. Rather, the shielding purpose can already be achieved if the second conductor element sheath, which surrounds the pair of conductor elements, is radially enclosed on all sides by the electrically conductive shielding bridge. It is preferred that all conductor element sheaths are radially enclosed on all sides by the electrically conductive shielding bridge, in particular, are in direct contact with the electrically conductive shielding bridge, so that the electrically conductive shielding bridge is cast directly around the conductor element sheaths and / or the second conductor element sheaths.

[0032] Since the electrically conductive shielding bridge particularly preferably forms a non-detachable connection between the outer shielding sheath and the inner shielding sheaths and the shield divider, the electrically conductive shielding bridge can also absorb mechanical forces between the outer shielding sheath on the one hand and the shield divider on the other, in particular tensile forces. The electrically conductive shielding bridge is preferably integrally connected to both the outer shielding sheath, the inner shielding sheaths, and the shield divider. The electrically conductive shielding bridge thereby forms a particularly seamless shield and mechanically anchors the cable to the connector.

[0033] The line elements belong either to a line or to a connector or preferably contact a line with a connector.

[0034] Preferably, the line elements are present in pairs of at least two line elements per pair, wherein the inner shielding sheaths are designed to shield the line elements in pairs from each other.

[0035] The electrically conductive shielding bridge preferably creates a material-to-material bond with the outer shielding sheath, the inner shielding sheaths and the shield divider, so that a material-to-material bond is formed from the shielding sheaths to the shield divider via the electrically conductive shielding bridge.

[0036] The shielding bridge preferably also extends between the line elements, whereby the shielding bridge preferably also closes the area between the line elements, so that an all-round shield enclosure of the individual line elements is achieved.

[0037] The shielding bridge is preferably made of a metal material. The shielding bridge can be cast around the conductor element sheaths using a metal casting process. The shielding bridge is preferably cast in situ around the conductor element sheaths and between the conductor elements, so that it radially encloses the conductor elements on all sides, particularly in a ring region of the cable length. In other words, the shielding bridge can be inserted seamlessly around and between the conductor element sheaths and thus the conductor elements, for example, cast in situ onto the partially assembled connector using a metal casting process to achieve seamless shielding of the connector.

[0038] The shielding bridge is preferably designed to anchor the inner shielding sheaths and the outer shielding sheath to the shield divider. In other words, the shielding bridge can also divert forces from the cable to the connector and vice versa. The shielding bridge thus not only improves the shielding effect of the cable but also provides strain relief or improves the effect of the strain relief of the cable at the connector.

[0039] The shield divider is electrically connected to the connector housing, in particular, manufactured as a single piece with the connector housing. For example, the connector housing is made of a metal material, such as die-cast zinc, and the shield divider is manufactured as a single piece with the connector housing using a die-casting process.

[0040] The shielding bridge is preferably made of a low-melting metal material, in particular a metal alloy, such as tin solder. When the shielding bridge melts at a lower temperature, the thermal effect or heat input to the conductor element sheaths is reduced, so that the conductor element sheaths do not melt, and electrical insulation of the conductor elements from the shielding bridge is maintained.

[0041] The shielding bridge can also be made of an electrically conductive plastic material or other electrically conductive material to achieve the shielding effect. The electrically conductive plastic material can also create a permanent connection between the outer shielding sleeve, the inner shielding sleeve(s), and the shield divider, for example, through an adhesive effect. Finally, the shielding bridge can also be designed, for example, to be attached to the outer shielding sleeve, inner shielding sleeves, and shield divider, for example, crimped or soldered, to establish the electrical, and in particular permanent, connection between them.

[0042] To improve the thermal insulation of the conducting element, or in particular of the conducting element sheaths, and optionally to ensure improved electrical insulation between the conducting elements and the shielding bridge and / or improved RF properties, second conducting element sheaths can be provided, which jointly enclose at least two conducting elements, wherein the electrically conductive shielding bridge encloses the second conducting element sheaths, in particular radially, on all sides. In other words, a further sheath is arranged on the conducting element sheaths, for example in the form of shrink tubing or a suitable plastic material, for example, also cast on, in order to further protect the conducting element sheaths against the thermal effects of the liquid shielding bridge during the manufacture of the shielding bridge.

[0043] The screen divider preferably has at least four screen bars arranged at the same angle to one another. These are, in particular, four screen bars of the screen divider arranged approximately at right angles to one another.

[0044] Preferably, a subset or a pair of two line elements is guided through each shielding sector, so that the shielding divider shields the subsets of line elements from one another, and each shielding bridge of the shielding divider is electrically and non-detachably connected, i.e. in particular materially connected, to the shielding bridge.

[0045] The shield divider may have an inner hollow element, for example to increase stability or to reduce the material required to manufacture the connector or the shield divider.

[0046] A coding device can preferably be arranged in the hollow element of the shield divider, wherein the coding device indicates the correct orientation of the line elements in the connector. In other words, a simple coding lug, for example, can indicate to the installer the orientation in which the connector housing should be arranged relative to the cables. For example, the line element sheath of each line element can have a specific color, so that the colors, together with the coding device, easily enable correct assembly in the correct position of the line elements or plug contacts.During assembly, it is no longer necessary to pay attention to the mating face, since the information about the orientation of the connector housing is already available on the back of the connector, i.e. where the line elements are inserted into the connector housing, using the coding device, so that the directionally correct assembly of the line elements in the connector housing can be carried out without errors.

[0047] Using the sealing inserts, the side from which the cable is routed to the connector housing (i.e., the cable side) can be fluid-tightly sealed from the interior of the connector housing (i.e., the connector side). The sealing inserts are designed to preferably seal each shielding sector separately. Therefore, several sealing inserts are preferably arranged radially around the shield divider, so that, for example, a sealing insert is arranged in each shielding sector, and each sealing insert provides a fluid-tight seal for each shielding sector.

[0048] These sealing inserts are advantageous when—as in one example of the present invention—the shielding bridge is introduced into the connector or onto the cable in molten form in order to predefine the extension area of ​​the shielding bridge toward a connector housing. Preferably, the molten material of the shielding bridge flows up to the respective sealing insert, but no further. At the same time, the sealing insert can be designed to effectively prevent electrical contact between the shielding bridge and the conductor element, even in the stripped area of ​​the conductor element. For this purpose, the conductor element can be inserted into the sealing insert to such an extent that the stripped area is completely covered by the sealing insert.

[0049] The connector housing may further comprise a radial shield which at least partially encloses the shield divider on the outside.

[0050] The sealing inserts can be arranged between the shield divider and the radial shield, providing an annular area that electrically and, if necessary, fluid-tight insulation between the cable side and the connector side. In other words, the shield divider and radial shield together can form a pocket in each shield sector, into which the sealing inserts are at least partially inserted. The sealing inserts can thus be inserted into the pocket formed in the respective shield sector or filled into it.

[0051] The sealing inserts can be made of plastic. A sealing insert can have openings for the wire ends of the conductor elements or contact elements to pass through or through. The sealing insert can, for example, have one, two, or more than two such openings. Suitably, a sealing insert has as many openings as there are conductor elements to be guided into a shield sector to improve the sealing effect. Sealing inserts can also be made of potting compound, which is cast in situ around at least two of the conductor elements to seal the cable side from the connector side. The potting compound can be epoxy resin or an adhesive material.

[0052] The sealing inserts can be produced using a molding process, so that a plastic part is already manufactured in a mold, such as a compression mold, before assembly into the connector and inserted into the connector. For example, the sealing insert can be created by pressing or crimping the conductor element sheaths into the respective shielding sector. The conductor element sheaths thus seal the respective shielding sector and provide a tight or fluid-tight seal between the cable side and the connector side.

[0053] The invention also provides a method for manufacturing a shielded electrical connector. The method comprises the steps: Exposing the outer shielding sheath, the inner shielding sheaths and the line element sheaths at one cable end, connecting one of the line elements to a contact element, arranging the line elements and / or the contact elements in partial quantities in each shield sector of the shield divider, attaching or applying the sealing inserts to or around each partial quantity in the area of ​​the shield divider, and inserting the electrically conductive shielding bridge onto and between the line elements and thereby irreversibly connecting the exposed shielding sheath, the exposed inner shielding sheaths and the shield divider to the electrically conductive shielding bridge.

[0054] The method can further provide for the shielding bridge to be inserted on and radially around the conductor element sheaths of the conductor elements.

[0055] Furthermore, it can be provided that the shielding bridge consists of liquid metal, which is poured in situ onto and between the line elements and solidifies in situ to form the shielding bridge.

[0056] The non-detachable connection can be a material connection, particularly in the form of a soldered connection.

[0057] Furthermore, the step of introducing the electrically conductive shielding bridge may comprise inserting the conductive elements with contact elements into a mold, closing the mold, and filling the mold with liquid metal material to produce the shielding bridge in situ around and between the conductive elements of the shielded electrical connector.

[0058] In the following, the invention is explained in more detail using exemplary embodiments and with reference to the figures, wherein identical and similar elements are partly provided with the same reference numerals and the features of the various exemplary embodiments can be combined with one another.

Detailed description of the invention

[0060] The Figures 1 to 6 show a first variant of sub-steps in the production of a cable connector 100. Figure 1 First, it shows a cable end 10 in which the ends 2a of the conductor elements 2 are exposed. The cable 10 has a cable sheath or cable insulation 4, which provides contact protection and comfortable handling of the cable 10. The cable sheath 4 is exposed in a ring area where the outer shielding sheath 20 is exposed. For example, the outer shielding sheath 20 is designed as a wire mesh. Adjacent, a section 4a of the cable sheath remains around the conductor elements 2.

[0061] The line elements are each combined in pairs and each pair of line elements 2 has an inner shielding sheath 24. Each individual line element 2 is further provided with a line element sheath 8. The line element sheath 8 provides electrical insulation for the line element 2 from its surroundings, in particular from the other line elements 2. Accordingly, the line element sheath 8 of each line element 2 is typically guided through the entire cable 10 and only at its ends, as in Figure 1 shown, exposed.

[0062] As in Figure 2As shown, sealing inserts 12 are pushed onto the exposed ends 2a of the conductor elements 2. The sealing inserts 12 have a cable side facing the inserted cable and a connector side facing the subsequent connector. Typically, the conductor elements are pushed through the sealing insert 12 from the cable side. Alternatively, the contact elements 14 can be arranged first at the conductor ends 2a, followed by the sealing inserts 12.

[0063] In the example of Figure 2Each sealing insert 12 has two through-openings, so that two conductor elements 2 can be inserted into each sealing insert 12. For example, the sealing inserts 12 are pushed onto the stripped conductor ends 2a until they are flush with the conductor element sheaths 8 or until the sealing inserts 12 partially cover the conductor element sheaths 8. In other words, each sealing insert 12 seals together with the conductor element sheaths 8. In this example, four sealing inserts 12 are threaded onto the eight conductor elements 2 shown, each in pairs, resulting in a ring-shaped arrangement of the four sealing inserts 12 at the stripped conductor end 2a.

[0064] As in Figure 3shown, contact elements 14 are then pushed onto the stripped conductor ends 2a and mechanically connected to the stripped conductor ends 2a, for example crimped or soldered or the like. The sealing inserts 12 are then fixed to the conductor elements 2 from both sides, with the conductor element sleeves 8, for example, abutting the sealing inserts 12 on the cable side and the contact elements 14 abutting the housing side of the sealing inserts 12. The sealing inserts 12 can also be fixed to the conductor elements 2, with the sealing inserts 12 being partially pushed onto the conductor element sleeves 8 and their position initially being fixed, for example, by clamping them to the conductor element sleeves 8. It may be sufficient for the sealing inserts 12 to initially only be sufficiently or partiallyare provisionally held in position, for example clamped, since a final and more stable positional fixing of the sealing inserts 12 can only take place, for example, when the shielding bridge 25 is cast on later.

[0065] Then to Figure 3 The housing part 30 can be threaded onto the contact elements 14. In other words, the contact elements 14 are inserted into the housing part 30. The sealing inserts 12 are positioned on the shield divider 35, specifically one sealing insert 12 in each shield sector 33. The shield divider 35 has a plurality of shield bars 34, with a shield sector 33 being formed between each two shield bars 34. Each shield sector 33 is, as it were, a receiving area for a sealing insert 12.

[0066] The shield divider 35 further comprises a radial ring 32, wherein the sealing inserts 12 are partially located under the radial ring 32, so that they seal the respective shield sector 33 together with the radial ring 32 in a media-tight manner.

[0067] Afterwards, as for example with the Figures 7 to 9 shown, the shielding bridge 25 is applied to the still exposed conductor element sheaths 8 of the conductor elements 2. As shown in Figure 5 As shown, a shielding bridge 25 is thus formed, which connects the outer shielding shell 20, the inner shielding shells 24 and the housing part 30 to one another in an electrically conductive and non-detachable manner, in particular in a materially bonded manner.

[0068] As with Figure 6As shown, a flexible sheath 50 is then applied to the connector 100, for example, for sealing and strain relief purposes, but also for aesthetic reasons and to provide protection against contact. This ultimately results in the commercially available shape of the connector 100.

[0069] The Figures 7 to 9 show the manufacture of the shielding bridge 25 in a casting mold 300. Figure 7 First, the empty mold 300 is shown, which has a filling opening for the material used to manufacture the shielding bridge 25, for example, a low-melting metal alloy. Furthermore, the mold 300 has a connector receiving opening 304, into which the connector 100 can be inserted. Typically, the mold 300 is constructed in the form of two halves, which can be coupled and closed together, wherein the Figures 7 to 9only show one half of the mold to make the structure easier to understand.

[0070] Figure 8 shows the casting mold 300 with inserted connector 100, wherein the part to be cast is open and the shielding bridge is to be cast onto the exposed line element sheaths 8, the sealing inserts 12, the shield divider 35 and the outer shielding sheath 20.

[0071] Figure 9 shows the mold 300 with the connector 100 inserted, with the shielding bridge 25 completely cast and hardened or cooled. The electrical connection from the housing part 30 to the outer shielding shell 20 and the inner shielding shell 24 is completed by means of the shielding bridge 25.

[0072] Figure 10shows a detailed top view of a housing part 30, which has a sealing ring 28, the shield divider 35 with radial ring 32 and shielding bars 34. The sealing ring 28 serves as a seal in the mold, particularly during the casting of the still liquid shielding bridge 25, i.e., in particular, the liquid metal. On the later finished connector 100, it can also be used together with the final overmolding, i.e., the flexible sheath 50, as a sealing element against the ingress of moisture. The ends of the contact sleeves 16 are inserted into the shielding sectors 33, each contact sleeve 16 having two through-openings 161, 162 (cf. Figure 13 ). Sealing inserts 12 are to be inserted into the remaining areas of the shield sectors 33, see Figure 18 . Finally, the housing part 30 has a screw thread 40 to connect the housing part 30 to another connecting part.

[0073] The shield divider 35 has an inner hollow part 38 in which a coding lug 36 is arranged. The coding lug 36 indicates the correct direction of connection of the line elements 2 to the respective shield sectors 33 of the housing part 30.

[0074] Figure 11 shows a housing part 30 with a shield divider 35 and four shielding bars 34. In this example, no contact sleeves 60 are provided or required. This form of the housing part 30 can be provided, for example, if an internal thread or a connection technique other than the screw thread 40 is to be provided on the far end of the housing part 30. For example, the embodiment of the Fig. 11 a detail of the Fig. 10 .

[0075] Figure 12shows another connector 100 in a partially assembled state, wherein the cable end 10 has been stripped of the cable insulation 4 and the conductor ends 2 have been exposed. The outer shielding sheath 20 can be contacted between the insulation 4 and the section 4a of the cable insulation, but also at the end section of the cable insulation 4. The stripped conductor ends 2a (compare for example Figure 1 ) are already equipped with the contact elements 14, which have been pushed up to the line element sheaths 8 or which are mounted in such a way that a small free area of ​​the line elements 2 remains between the contact elements 14 and the line element sheaths 8.

[0076] A contact sleeve 16, which can accommodate two contact elements 14 in pairs, can be particularly advantageously pushed onto the contact elements 14. The contact sleeve 16 is pushed onto the contact elements 14 in such a way that the contact elements 14 are inserted into the through-openings 161, 162 and the contact sleeve 16 is guided up to the conductor element sheaths 8. For better insulation, the contact sleeve 16 also has an insulating collar 163 between the two through-openings 161, 162. Finally, the contact sleeve 16 also covers the majority of the contact elements 14 by means of the sleeve extension 164.

[0077] Figure 14 shows the with according to Figure 13 described contact sleeves 16 in a partially assembled state, with two line elements 2 being inserted into a contact lens 16. Since the cable 10 of the example of the Figure 14has eight line elements 2, four contact sleeves 16 are provided, into each of which two line elements 2 are inserted.

[0078] Figure 15 shows the Figure 14 An alternative embodiment in which the conductive elements 2 are twisted or intertwined in pairs in the exposed region, a so-called "twisted-pair arrangement." The conductive elements 2, which are twisted or intertwined in the exposed region, are inserted in pairs into a contact lens 16.

[0079] Figure 16 shows an alternative embodiment to Figures 14 and 15 , which may also be cumulatively equipped with it, where appropriate Figure 16in the freed area, has second conductor element sheaths 9, wherein the conductor elements 2 arranged in pairs are inserted in pairs into second conductor element sheaths 9. The second conductor element sheaths 9 are in particular each a piece of shrink tubing or an electrically insulating material.

[0080] Figure 17 now shows the embodiment of the Figure 14 with a housing part 30 attached, which is pushed onto the conductor elements 2 or the contact elements 14 from the front until the contact sleeves 16, with their ends or with the through-openings 161, 162, are positioned in the respective shielding sector 33, for example, below the radial ring 32. If necessary, a small piece of stripped conductor end 2a can also protrude from the contact sleeves 16. This is advantageously not essential, since these areas will be covered later.

[0081] Figure 18shows an embodiment of a sealing insert 12 prepared for insertion into a shield sector 33 of the shield divider 35. The sealing insert 12 has a first and a second passage opening 121, 122 for the passage of line elements 2. In the Figure 18 In the embodiment shown, these are two through-openings 121, 122, so that a pair of line elements 2 can be guided through a sealing insert 12. In other words, a sealing insert 12 seals a pair of line elements 2 in a media-tight manner. The connector 100 in the assembly form as shown in Figure 19 shown, can now be provided with the shielding bridge 25. Advantageously, the shielding bridge 25 is inserted in an area from the outer shielding sheath 20 over the section of the cable insulation 4a, the exposed line element sheaths 8, the sealing inserts 12, the shield divider 35 and up to the sealing ring 28. This can be done, for example, with a casting mold, as shown in Figure 7, be performed.

[0082] Figure 20shows the connector 100 with an inserted shielding bridge 25 for producing the shielding sheath, in particular a continuous shielding sheath from the outer shielding sheath to the sealing ring 28, wherein the inner shielding sheaths 24 are also through-plated and, by means of the shield divider 35, also through-plated internally between the line elements 2. Thus, the intermediate shielding between the line elements 2, in particular between the pairs of line elements 2 to the remaining line elements 2, remains intact over the entire length of the connector 100 as well as over the entire extension length of the line elements 2 from the piece connector 100 into the cable 10. Advantageously, the material of the shielding bridge 25 flows between the line elements 2 by pouring the shielding bridge 25 directly onto the line element sheaths 8 and there flowing between the line elements 8, 2.In other words, with the applied shielding bridge 25, each line element 2 is radially surrounded on all sides by the material of the shielding bridge 25, in particular thus to the remaining line elements 2 of the other line element pairs. Furthermore, the shielding bridge 25 is also through-plated with the shield divider 35 and in particular with all shielding webs 34 of the shield divider 35. It is particularly advantageous if a material-to-material connection is made between the shielding bridge 25 and the shielding webs 34 of the shield divider 35. It is likewise preferred if the same material-to-material contact can also be created with the outer shielding sheath 20 and the inner shielding sheaths 24, so that the shielding bridge 25 provides a material-to-material connecting bridge from the shield divider 35 via the shielding bridge 25 to the outer shielding sheath 20 or the inner shielding sheaths 24.

[0083] Figure 21 finally shows the connector Figure 20, wherein a protective sheath 50 is applied to the area of ​​the shielding bridge 25, for example by overmolding, as is commercially available. If necessary, the protective sheath 50 can be clamped or crimped to secure the position on the cable 10 or to provide strain relief and / or media tightness.

[0084] Figure 22 shows a plan view of a connector 100 in the fully assembled state, with the section lines A and B showing the views of the Figures 23, 24 and 25 should represent. Figure 23 shows a longitudinal section through a connector as it is used with Figure 22 along the line AA. The Figure 23 The connector 100 shown is shown in the fully assembled state, with the protective sheath already applied. In the longitudinal section of the Figure 23The profile of the shielding bridge 25 is clearly visible, extending around the conductor elements 2, between the conductor elements 2, and beyond the section 4a of the cable insulation 4. The shielding bridge 25 makes contact with the housing part 30, 32 in a materially bonded manner, thus completely establishing the shielding bridge. On the inside, the shielding bridge 25 contacts the shield divider 35.

[0085] The cable has a cable core 5, which is used, for example, to improve the symmetry of the cable (due to the RF properties) and / or to stiffen the cable. In the example shown here, the cable has two conductor elements 2, each surrounded by a conductor element sheath 8. An inner shielding sheath 24 surrounds each conductor element 2. In addition, the cable as a whole is shielded from the environment by the outer shielding sheath 20. On the outside, the cable 10 has the cable insulation 4.

[0086] The conductor elements 2 are inserted into contact elements 14 at their stripped conductor ends 2a and secured therein. Contact sleeves 16 are arranged around the contact elements 14 to accommodate the contact elements 14. Sealing inserts 12 are arranged in the area of ​​the shield divider 35 to seal the contact sleeves 16 or the plug side in a media-tight manner from the shielding bridge 25 or the cable side of the shield divider. The cable 10, as shown in Figure 23 shown, can also have a plurality of line elements 2, which in the representation of the Figure 23 are not shown due to the chosen perspective.

[0087] Figure 24shows another example of a connector 100 in the fully assembled state, wherein a plurality of eight conductor elements 2 in the housing part 30 are contacted at contact elements 14. By way of example, two conductor elements 2 are shown in sectional profile, wherein the conductor elements 2 are each enclosed by a conductor element sheath 8. The shielding bridge 25 is cast in situ from cast metal material, in particular a low-melting metal alloy, onto the conductor elements 2 or their conductor element sheaths 8, so that the shielding bridge 25 preferably extends radially in one piece on all sides around each of the conductor elements 2. Furthermore, the shielding bridge 25 contacts both the outer shielding sheath 20 and the inner shielding sheath 24 in order to contact both or all of the shielding sheaths 20, 24 with the shielding contacts 28, 35 of the housing part 30 of the connector 100.In particular, the conductor shielding effect between the pairs of conductor elements 2 is maintained completely and without gaps.

[0088] Figure 25 shows a radial section along the section line AA as in Figure 22 shown. In the area of ​​the shield divider 35, the line elements 2 are guided through four sealing inserts 12, with one sealing insert 12 arranged in each shield sector 33. The coding device 36 indicates the correct orientation of the line elements 2 on the housing part 30 during assembly.

[0089] Figure 26 shows an embodiment of the housing part 30 of the connector 100, wherein the contact sleeves 16 are located in the area of ​​the shield sectors 33 of the shield divider 35. The contact lenses 16 extend through the housing part 30 to just before the mating face 18 (see Figure 31). For example, the housing part 30 can be provided in this partially assembled form with pre-assembled contact sleeves 16 for the further assembly of the connector, so that the line elements 2 provided with contact elements can be inserted into the contact sleeves 16 and thus equally into the housing part 30.

[0090] Figure 27 shows a side view of a connector 100 in the fully assembled state, with the sections shown below along the section lines A, B and D or the front view E with the Figures 27a, 27b, 27c and 30 are shown.

[0091] Figure 27a shows a radial section along the section line AA, as in Figure 27specified, i.e., in the area through the shielding bridge 25, which radially encloses all line elements 2 individually on all sides, i.e., also each pair of line elements among themselves, as well as the pairs of line elements 2 to the other pairs of line elements 2. In this area, the line elements 2 are each electrically enclosed by line element sheaths 8. The line elements 2 therefore do not have an electrical shielding insert 25.

[0092] Figure 27b shows a Figure 27a alternative embodiment, which also has a radial section along the section line BB in the area of ​​the shielding bridge 25 of the connector 100, as in Figure 27shown. Each pair of line elements 2 is additionally enclosed by a second line element sheath 9. From the inside to the outside, a line element 2 is thus first radially enclosed on all sides by the line element sheath 8, then radially enclosed on all sides by the second line element sheath 9, and then again preferably radially enclosed on all sides by the shielding bridge 25. Depending on the embodiment, the area between a pair of line elements 2, i.e. the area within the second line element sheath 9, is not filled by the shielding bridge 25. Nevertheless, it is clear that in this case too, each line element 2 is preferably radially enclosed on all sides by the shielding bridge 25. For example, the Figure 27bThe conductor element 2 numbered top left is adjacent to its partner, which is arranged in the same second conductor element sheath 9. This partner lies in an imaginary alignment from the conductor element 2 to the next pair of conductor elements 2. Nevertheless, material from the shielding bridge 25 is located between this conductor element 2 and the next pair of conductor elements 2, which is enclosed by another second conductor element sheath 9. Material from the shielding bridge 25 is thus arranged around each conductor element 2 in all radial directions.Of particular importance here is that material of the shielding bridge 25 is arranged between each pair of line elements 2, which is enclosed by a common second line element sheath 9, and the other pairs of line elements 2, which are enclosed by other second line element sheaths 9, thus creating a shielding effect between the line element pairs 2. The pairs of line elements 2 are thus also shielded from each other.

[0093] Figure 27c shows a radial section along the section line DD, as in Figure 27indicated, i.e. in the area of ​​the cable 10. Each pair of conductor elements 2 is shielded from the other pairs of conductor elements 2 by an inner shielding sheath 24. Furthermore, the outer shielding sheath 20 also surrounds all of the conductor elements 2 together. The conductor pairs, each inserted into an inner shielding sheath 24, are inserted into cable filling material, such as cable rubber, and thus fixed. The inner shielding sheath 24 can, for example, be a thin aluminum foil or a plastic film onto which aluminum or another metal material has been vapor-deposited. Metal material is preferred for insulation. If the inner shielding sheath 24 and / or the outer shielding sheath 20 is made of a metal material or comprises a metal material, a material-to-material bond with the shielding bridge 25 can be created.

[0094] Figure 28shows a further alternative embodiment of a partially assembled connector 100, wherein the line elements 2 are arranged twisted in the still exposed area and are inserted into the contact sleeves 16.

[0095] Figure 29 shows yet another alternative embodiment of the partially assembled connector 100, wherein the respective pairs of line elements 2 are each provided with a second line element sheath 9 such as a shrink tube.

[0096] Figure 30 shows a front view of a connector 100 as shown in Figure 27 along the section line EE. This radial section is arranged within the housing part 30, so that the radial section passes through the contact sleeves 16 and the shield divider 35. The contact elements 14 are arranged in the contact sleeves 16. Furthermore, in Figure 30 the section line C1 is shown, which is the longitudinal section of the Figure 31 indicates.

[0097] Figure 31 shows a longitudinal section along the section line C1-C1 of the Figure 30 by a pre-assembled connector 100. The cable 10 has a plurality of line elements 2, which are plugged into contact elements 14 in the housing part 30. The shielding bridge 25 surrounds the line elements 2 in the connection area between the cable 10 and the housing part 30, preferably radially on all sides, thus also between the line elements 2. The shielding bridge 25 extends from an open area between the section 4a of the cable insulation and the cable insulation 4 on the cable side to the contact ring 28 of the housing part on the housing side and thereby contacts the shield divider 35 as well as the inner shielding sleeves 24 and the outer shielding sleeve 20.

[0098] Figure 32shows an embodiment of the fully assembled connector 100, which is screwed into a mounting part 44 with a printed circuit board or mounting plate 42.

[0099] Figure 33 shows a top view of the plug-in face 18b of the mounting part 44. The plug-in face 18b is arranged on a printed circuit board or mounting plate 42.

[0100] Figure 34 finally shows a longitudinal section through the connector 100 according to the Figure 32 with mounted mounting part 44.

[0101] The present invention thus describes a connector 100 in which, in a particularly economical and effective manner, complete shielding of individual wires 2 of a cable 10 can be achieved not only with the outer shield 20, but also shielding between at least the individual pairs of line elements 2 from one another. A shielding bridge is introduced into the exposed area between cable 10 and housing part 30 in such a way that the shielding bridge 25 also extends between the individual line elements 2 or at least between the pairs of line elements 2, so that each line element 2 in this area is radially enclosed on all sides by the material of the shielding bridge 25, i.e., in particular, radially enclosed on all sides by the shielding bridge 25.Thus, seamless and complete shielding can be achieved both outwardly with respect to the outer shielding and thus the outer shielding sheath 20, and also between the line elements 2 among themselves, i.e., toward the inner shielding sheath 24 of the respective pair of line elements, as well as toward the shielding divider 35 and the housing part 30, 32. A one-piece shielding bridge is used, which also creates a non-detachable connection from the shielding elements 20, 24 of the cable 10 to the contact elements 28, 35 of the housing part 30. The non-detachable connection provided by the shielding bridge 25 is in particular a material-to-material connection, for example, by a soldering process. The presented shielding bridge 25 is preferably cast in situ from a metal material in the shown annular region directly and immediately onto the line element sheaths 8 or second line element sheaths 9.

[0102] It will be apparent to those skilled in the art that the embodiments described above are to be understood as examples and that the invention is not limited to them, but can be varied in many ways without departing from the scope of the claims. Furthermore, it is clear that the features, regardless of whether they are disclosed in the description, the claims, the figures or otherwise, also individually define essential components of the invention, even if they are described together with other features. In all figures, the same reference numerals represent the same objects, so that descriptions of objects that may only be mentioned in one figure or at least not with regard to all figures can also be transferred to those figures with regard to which the object is not explicitly described in the description.
