Description

TECHNICAL FIELD

[0001] The present invention relates to a shielded electrical connector and to a method for manufacturing a shielded electrical connector. BACKGROUND

[0002] Methods are known in which a cable is equipped with a shielding device when connected with a plug-in connector. For example, solutions are known in which a crimp sleeve and a locking nut are used, see German patent DE 196 13 228 B4.

[0003] 13 228B4.

[0004] In another variant, it is proposed in US 5,906,513, for example, to press a sleeve-like housing with tabs onto the metal braid shielding device of a cable and then to overmold it with a thermoplastic.

[0005] A method is known from DE 10 2008 018 403 Al in which a shielding device composed of electrically conductive plastic is used.

[0006] The document WO 2016 135 170 Al from the company of the present applicant describes a method in which a shielding device is manufactured by a metal casting method. The present application can be seen as a further extension of the above-mentioned patent application, so that WO 2016 135 170 Al is incorporated by reference.

[0007] In addition to the aforementioned disadvantages of the prior art already mentioned in WO 2016 135 170 Al, the known methods for shielding a connector require a troublesome assembly in part and can have different contact resistances on the contact areas of the shielding device, in particular due to temperature and aging of the materials used.

[0008] Furthermore, all known methods only provide for the connection of the outermost shielding sleeve of a cable on a plug-in connector.

[0009] However, a cable according to the invention can be used in which the conductors arranged in the cable can or should have a supplementary wire shielding device. In order to reduce or suppress signal crosstalk from different conductors into the respective other conductors, it can therefore even be advantageous or desirable that the respective conductors or subsets of conductors of the cable, which are mutually shielded by a conductor shield, also continue or continue the shielding effect in the region of the plug-in connector, so that no crosstalk occurs between the conductors. This is not provided or possible in the known methods. SUMMARY

[0010] It is an object of the present invention to provide a shielded electrical connector which has a good shielded connection between the shielded electrical wires and the shielded plug-in connector.

[0011] It is another aspect of the present application to provide a durable shielded electrical connector, wherein the contact resistance between the relevant components of the shielding means remains low over the service life of the connector.

[0012] The shielded electrical connector can thus be produced in an advantageous manner simply and largely mechanically, and has, in particular, as few parts as possible in order to further simplify assembly.

[0013] In this context, particular attention is given to connecting such shielded electrical conductors with plug connectors, wherein individual conductors or subsets of the conductors of the electrical cable have a sub-shielding means or subordinate shielding means, such that this sub-shielding means or subordinate shielding means can also perform its function in the region of the plug connector and, in particular, likewise connects with the shielding means.

[0014] The object of the present application is achieved by the subject matter of the independent claims. Advantageous refinements of the present application are defined in the dependent claims.

[0015] The shielded electrical connector comprises a plurality of conductive elements, i.e. at least two conductive elements, which belong to the electrical cable or to the plug connector. The conductive elements are, for example, part of an electrical cable which is to be connected with contact elements of the plug connector. Typically, each conductive element comprises a conductive element jacket for electrically insulating the respective conductive element. The shielded electrical connector thus comprises a plurality of conductive element jackets, wherein typically each conductive element has its own conductive element jacket. The plurality of conductive element jackets is thus at least two conductive element jackets. The conductive element jackets can be, for example, plastic sheaths, rubber sheaths or any type of core insulation. It is also conceivable for the conductive element jackets to be shrink hoses or to be applied afterwards when the plug connector is assembled.

[0016] Furthermore, an outer shielding jacket is comprised which at least partially or at least regionally surrounds the plurality of conductive elements. Typically, the outer shielding jacket surrounds the conductive elements completely, i.e. through-going, in the region of the non-opened electrical cable, that is to say from the first end of the electrical cable up to the second end of the electrical cable. Thus, a shielding effect along the entire electrical cable can be achieved by means of the outer shielding jacket, wherein in a preferred embodiment the shielding jacket can also be grounded on at least one end of the electrical cable, for example at the contact ring of the housing part, at one or more plug connectors. In other words, the outer shielding jacket collectively surrounds all of the conductive elements, so that the conductive elements are collectively arranged on the inside of the outer shielding jacket and are shielded from the surroundings by means of the outer shielding jacket.

[0017] In the region of the connection of the electrical cable with the plug connector, the outer shielding jacket is exposed in order to access the conductive elements for the purpose of contacting the contact elements. This exposure is preferably effected by a machine, so that uniform annular regions of the outer shielding jacket are respectively exposed, for example on the cable end.

[0018] Furthermore, at least one inner shield sleeve is included which collectively at least partially or at least regionally surrounds a subset of the conducting elements in order to shield against the remaining conducting elements. For example, the conducting elements can be combined in pairs, respectively, and are provided with a respective inner shield sleeve in pairs. In one example, the cable includes a total of eight conducting elements which are surrounded by inner shield sleeves in pairs, respectively, so that in this example four inner shield sleeves are included which are collectively also surrounded once by an outer shield sleeve. The subset of conducting elements includes at least one conducting element, typically two conducting elements. The subset can include a different number of conducting elements. Preferably and provided, one conducting element is assigned here to exactly one subset. It can then also be provided in a cable including different conducting elements that only a subset of the conducting elements has an inner shield in order to, for example, additionally shield a current-carrying core wire from a signal-carrying core wire in a common cable. In one preferred case, a first subset of conducting elements, for example, of signal-carrying, is surrounded by a first inner shield sleeve, and a second subset of conducting elements, for example, also of signal-carrying, is individually surrounded by a second inner shield sleeve.

[0019] Furthermore, a connector housing is also included in which the plurality of conducting elements, in particular the contact elements, can be contacted. Typically, the connector housing also includes a plug-in face for connecting to another conducting component or for contacting the conducting elements with a next assembly.

[0020] The shielded electrical connector also includes a shield partition which forms at least two shield sections. For example, the shield partition has at least two shield ribs, wherein a radial area between the two shield ribs respectively forms one of the shield sections. At least one conducting element can be guided through one shield section. Preferably, one of the subsets of conducting elements is guided through one shield section, and more precisely a subset in which the individual conducting elements of the subset do not have to be shielded from one another, but only from the remaining conducting elements of the cable.

[0021] Furthermore, at least one sealing insert is included for sealing the cable side in the area of the shield partition from the plug side. In other words, the sealing insert is provided for providing a fluid-tight barrier so that a fluid exchange from the cable side to the plug side and / or vice versa is no longer possible. In other words, the sealing insert or the sealing inserts provide a fluid barrier in the axial direction, thus preventing a fluid exchange between the plug side and the cable side. The sealing insert is thus also responsible for preventing the ingress of liquid material from the cable side into the plug side and thus into the plug.

[0022] Here, either the conducting elements pass through the sealing insert or the sealing insert is applied to one or more of the respective conducting elements, for example sprayed or shaped in a shaping process. For example, a plurality of sealing inserts are provided, for example arranged or for embedding or spraying, injecting into the shielding sections, in particular one sealing insert is provided in each shielding section.

[0023] Furthermore, an electrically conductive shielding bridge is included for electrically, in particular non-detachably, connecting the outer shielding jacket at least with the one or more inner shielding jackets and the shielding partition. In other words, the electrically conductive shielding bridge or the sealing insert provides an electrical bridge which connects the outer shielding jacket with the inner shielding jackets and the shielding partition with as little electrical resistance as possible.

[0024] In this case, the electrically conductive shielding insert or the electrically conductive shielding bridge is able to establish a non-detachable connection between the outer shielding jacket, the inner shielding jackets and the shielding partition, wherein the electrically conductive shielding bridge is preferably arranged integrally around the conducting element sleeve. Here, it is particularly preferred that the electrically conductive shielding bridge is able to encompass the conducting element sleeve radially overall. This means that the electrically conductive shielding bridge is also arranged between the conducting elements. In other words, the shielding bridge is also responsible for the electrical conductivity of the inner shielding jackets to the shielding partition and the outer shielding jacket, whereby the inner shielding effect or interconductor shielding is also maintained, in particular completely and / or gaplessly. In other words, the electrically conductive shielding bridge is able to provide an electrical shielding effect, in particular gaplessly, from the electrical cable via the region in which the cable is open near the connector housing and through the shielding partition to the connector housing, wherein the inner shielding effect is also maintained, more precisely in particular gaplessly, between the subset of conducting elements.

[0025] If the conducting elements are each provided individually with a conducting element sleeve, it is particularly advantageous if the electrically conductive shielding bridge is arranged between each conducting element, that is to say between all of the conducting elements. In other words, the electrically conductive shielding bridge itself encompasses each conducting element radially overall. In the case of a subset of conducting elements having a common second conducting element sleeve, for example in the form of a shrink hose, for example applied to a pair of conducting elements respectively, then the electrically conductive shielding bridge likewise encompasses all of the conducting element sleeves radially overall, wherein the intermediate region between the pair of conducting elements is kept as free of the electrically conductive shielding bridge as possible. In other words, the interior of the second conducting element sleeve is not filled by the electrically conductive shielding bridge in this case, but is arranged around the respective second conducting element sleeve. In this case, the electrically conductive shielding bridge also encompasses the pair of two conducting elements with the second conducting element sleeve and thereby also encompasses each conducting element radially overall.

[0026] In other words, a practical example is that each conducting element has a separate conducting element jacket, i.e. in particular a core insulation. An electrically conductive shielding bridge is then introduced, which completely surrounds the conducting elements, i.e. in particular each conducting element in the radial direction, and thus preferably extends between the individual conducting elements, i.e. flows between the conducting elements in the liquid state and is distributed there in such a way that the associated component is produced as an electrically conductive shielding bridge. The conducting element jacket is designed to withstand the thermal load during the introduction of the shielding bridge, so that no electrical contact is produced between the conducting elements and the shielding bridge. Thus, for example, the conducting element jacket is designed not to melt when the electrically conductive shielding bridge is applied, so that no short circuit is produced between one of the conducting elements and the shielding bridge. Thus, no electrical connection between the conducting elements and the electrically conductive shielding bridge is provided or exists in the region in which the shielding bridge is embedded. If necessary, one of the conducting elements, in particular the ground connection, can in a special embodiment come into contact with the shielding bridge in the plug; this should not be excluded here. However, it is preferable if there is no electrical contact between the conducting elements and the shielding bridge, but rather the shielding bridge achieves the electrical shielding of the conducting elements from one another and the electrical shielding of the conducting elements from the environment.

[0027] Thus, the electrically conductive shielding bridge is arranged around the conducting elements and also between the conducting elements, and a one-piece, i.e. monolithic, component is formed as the shielding bridge. The electrically conductive shielding bridge, which is one-piece, i.e. monolithic, directly and immediately connects the outer shielding jacket to the inner shielding jacket and the shielding partition as a continuous component. This establishes a firm and reliable electrical connection of the three aforementioned components, i.e. the outer shielding jacket, the inner shielding jacket(s) and the shielding partition, to one another, which can be provided in particular without gaps by means of the shielding bridge between and around the conducting elements. Here, the reliable contact of all the aforementioned components to one another can ensure a simplification of the manufacturing process, since it can no longer be necessary to check the electrical contact. Here, the one-piece component of the shielding bridge, which electrically connects all the aforementioned components to one another in particular firmly and fusion-free, has a lower electrical resistance compared to a multi-part shielding device. A multi-part electrical shielding device can also require further work steps when manufacturing. On the other hand, the shielding, which is in particular constructed without gaps, of the shielding bridge can improve the signal quality and / or reduce signal attenuation, in particular in high-frequency applications, i.e. in HF technology, and / or in applications in which external interference fields are to be expected.

[0028] Thus, a particular feature that can be achieved with the shielding bridge according to the application is that the outer shield, the inner shield(s), and the shielding partition, in particular of the electrical cable, are electrically connected to one another in a monolithic structural manner. Thereby, potential defect sites of the shielding are avoided, reduced, or prevented. Unlike a possibly multipart shielding bridge, there are no longer "step sites" in which a gap-free connection, for example, also depends on the attachment of the connection to the intermediate piece and, in this case, the possibility of providing the shielding bridge completely without a gap. Thus, in the case of a multipart shielding bridge, the different components can come loose from one another in the case of vibrations in use, for example, in operation, or in the case of a collision, so that only an insufficient or interrupted contact can be established in the shielding. These problems can be eliminated or improved by the monolithic shielding bridge presented here. Thus, the monolithic structure of the shielding bridge ensures or improves the electrical contact of the three shielding elements (outer shield, inner shield(s), shielding partition) to one another and at the same time enables an as comprehensive and complete a shielding of the conductive elements as possible in the region in which the shielding bridge is arranged.

[0029] It can also be provided that the conductive elements are deinsulated over a longer section, i.e., for example, in the axial direction toward the direction of the electrical cable up to the protruding shielding section, and that a cover, for example, an injection-molded plastic, is applied first on the deinsulated end of the conductive elements. An electrically conductive shielding insert can also be applied to the cover.

[0030] It is preferred that the conductive elements are deinsulated only up to the sealing element, and that in the region in which the electrically conductive shielding bridge is cast, in particular, the conductive element sleeves are intact, and thus the shielding bridge is cast, for example, directly onto the conductive element sleeves. Thus, the material of the shielding bridge also reaches between the subsets of conductive elements, preferably between the individual conductive elements.

[0031] In terms of the shielding, it can not be important here whether the conductive elements arranged together in pairs or subsets, respectively, do not have a shielding with the electrically conductive shielding bridge from one another, but rather the shielding purpose is already achieved when the second conductive element sleeve that surrounds the pair of conductive elements is radially comprehensively surrounded by the electrically conductive shielding bridge. Preferably, all of the conductive element sleeves are radially comprehensively surrounded by the electrically conductive shielding bridge, in particular in direct contact with the electrically conductive shielding bridge, so that the electrically conductive shielding bridge is cast directly around the conductive element sleeves and / or the second conductive element sleeve.

[0032] Since the electrically conductive shielding bridge in particular preferably forms an inseparable connection of the outer shielding sleeve with the inner shielding sleeve and the shielding partition, the electrically conductive shielding bridge can also absorb mechanical forces, in particular tensile forces, between the outer shielding sleeve on the one hand and the shielding partition on the other hand. Preferably, the electrically conductive shielding bridge is connected in a material-fit manner not only with the outer shielding sleeve, the inner shielding sleeve, but also with the shielding partition. Here, the electrically conductive shielding bridge forms a mechanical anchoring of the shielding and the cable on the plug connector, in particular without gaps.

[0033] The conductive element belongs to the conductor wire or the plug connector or preferably brings the conductor wire into contact with the plug connector.

[0034] Preferably, the conductive elements are present in pairs, each pair having at least two conductive elements, wherein the inner shielding sleeve is designed to shield the conductive elements from each other in pairs, respectively.

[0035] The electrically conductive shielding bridge preferably establishes a material-fit connection with the outer shielding sleeve, the inner shielding sleeve and the shielding partition, so that a material-fit connection from the shielding sleeve up to the shielding partition is formed by the electrically conductive shielding bridge.

[0036] The shielding bridge preferably also extends between the conductive elements, wherein the shielding bridge preferably also encloses the region between the conductive elements, so that the individual conductive elements are fully shielded from each other.

[0037] The shielding bridge is preferably made of a metallic material. The shielding bridge can be cast around the conductive element sleeve here by means of a metal casting method. The shielding bridge is preferably cast in situ around the conductive element sleeve and between the conductive elements, so that it radially fully surrounds the conductive elements, in particular in the annular region of the cable length. In other words, the shielding bridge can be introduced around the conductive element sleeve and thus the conductive elements without gaps, i.e. cast in situ onto the partially assembled plug connector by means of a metal casting method, for example, in order to achieve a gap-free shielding of the plug connector.

[0038] Preferably, the shielding bridge is designed to provide an anchoring of the inner shielding sleeve and the outer shielding sleeve to the shielding partition. In other words, a force action of the cable on the plug connector and vice versa can also be derived by means of the shielding bridge. Thus, the shielding bridge not only improves the shielding of the cable, but also provides a stress relief or improves the stress relief effect of the cable on the plug connector.

[0039] The shielding partition is electrically connected to the connector housing, in particular is manufactured in one piece with the connector housing. For example, the connector housing is made of a metallic material, such as a zinc die cast, and the shielding partition is manufactured in one piece with the connector housing by means of a die casting process.

[0040] The shielding bridge is preferably made of a low-melting metal material, in particular a metal alloy, for example a tin solder. If the shielding bridge melts at low temperatures, the thermal effect or heat input on the conductor element sleeve is lower, so that the conductor element sleeve does not melt and the electrical insulation of the conductor element 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 in order to achieve the shielding effect. The electrically conductive plastic material can here, for example, also create a non-releasable connection between the outer shielding sleeve, the inner shielding sleeve(s) and the shielding partition by adhesive action. Finally, the shielding bridge can also be designed, for example, such that it is fixed, for example, crimped or soldered, to the outer shielding sleeve, the inner shielding sleeve and the shielding partition in order to establish an in particular non-releasable electrical connection between them.

[0042] In order to improve the thermal insulation of the conductor element or in particular of the conductor element sleeve and, if necessary, to provide an improved electrical insulation and / or improved HF properties between the conductor element and the shielding bridge, a second conductor element sleeve can be provided which collectively surrounds at least two conductor elements, wherein the electrically conductive shielding bridge in particular completely surrounds the second conductor element sleeve in the radial direction. In other words, a further sleeve is arranged on the conductor element sleeve, for example in the form of a shrinkable hose or a suitable plastic material, for example also cast onto it, in order to better protect the conductor element sleeve from the thermal effect of the liquid shielding bridge during the manufacture of the shielding bridge.

[0043] The shielding partition preferably has at least four shielding ribs which are arranged at equal angles to one another. This is in particular the case with four shielding ribs of the shielding partition which are arranged at approximately right angles to one another.

[0044] Preferably, a subset or pair of two conductor elements is threaded through each shielding section, so that the shielding partition screens the subsets of conductor elements from one another, and wherein each shielding rib of the shielding partition is electrically and non-releasably, in particular materially bonded, connected to the shielding bridge.

[0045] The shielding partition can have an inner hollow element, for example for increasing the stability or reducing the material requirement for manufacturing the plug connector or the shielding partition.

[0046] The coding means can preferably be arranged in the hollow elements of the shielding partition, wherein the coding means indicate a correct arrangement of the conducting elements in the connector. In other words, for example, simple coding protrusions can indicate to the installer in which orientation the connector housing should be arranged relative to the cable. Thus, for example, the conducting element jacket of each conducting element can have a specific color, whereby the correct installation of the conducting elements or the plug-in contacts in the correct position is achieved in a simple manner by means of the color together with the coding means. Here, it is not necessary to pay attention to the plug-in face when assembling, since when assembling, on the back side of the plug-in connector, i.e. where the conducting elements are introduced into the connector housing, information is provided by means of the coding means as to in which orientation the connector housing can implement the correct arrangement of the conducting elements in the connector housing without errors.

[0047] By means of the sealing insert, the cable can be sealed liquid-tightly from its side, i.e. the cable side, to the interior region of the plug housing, i.e. the plug side. Here, the sealing insert is set up to seal each shielding section, preferably individually. Thus, here, preferably a plurality of sealing inserts are arranged radially around the shielding partition, so that, for example, one sealing insert is arranged in each shielding section and each sealing insert seals one shielding section, respectively, liquid-tightly.

[0048] When the shielding bridge is introduced into the connector or on the cable, as in one example of the application, moltenly, these sealing inserts facilitate a predefined extension of the shielding bridge in the direction of the connector housing. The molten material of the shielding bridge preferably flows to the respective sealing insert, but not further. At the same time, the sealing insert can be arranged to also very effectively prevent electrical contact between the shielding bridge and the conducting element in the deinsulation region of the conducting element. To this end, the conducting element can be inserted into the sealing insert to such an extent that the deinsulation region is completely covered by the sealing insert.

[0049] Furthermore, the connector housing can have a radial shielding which at least partially surrounds the shielding partition on the outside.

[0050] The sealing insert can here be arranged between the shielding partition and the radial shielding and electrically insulate and, if necessary, fluid-tightly isolate the cable side from the plug side in the annular region. In other words, the shielding partition and the radial shielding can together form a pocket-like portion in each shielding section to which the sealing insert is at least partially inserted. The sealing insert can be inserted into or filled into the pocket-like portion formed in the respective shielding section.

[0051] The sealing insert can be made of plastic. The sealing insert can have a through-hole for the passage or insertion of a core wire end of a conducting element or of a contact element. The sealing insert can have, for example, one, two or more than two such through-holes. Suitably, the sealing insert has as many through-holes as conducting elements that are to be guided into the shielding section, in order to improve the sealing effect. The sealing insert can also be made of a casting material that is cast in situ around at least two of the conducting elements, respectively, for sealing the cable side from the plug side. The casting material can be an epoxy resin or an adhesive material.

[0052] The sealing insert can be produced by means of a molding process, so that the plastic part is already produced in a mold, for example a press mold, before being fitted into the plug connector and inserted into the plug connector. For example, the sealing insert can be produced by pressing or extruding a conducting element sleeve into or onto the respective shielding section and thus enclosing the respective shielding section and providing a sealing or liquid-tight closure between the cable side and the plug side.

[0053] According to the application, a method for producing a shielded electrical connector is also provided. The method comprises the following steps:

[0054] - exposing the outer shielding sleeve, the inner shielding sleeve and the conducting element sleeve at the cable end,

[0055] - connecting each of the conducting elements with a respective contact element,

[0056] - arranging the conducting elements and / or the contact elements in pairs as conductor pairs in each one of the shielding sections of the shielding partition,

[0057] - arranging or applying a sealing insert to or around each conductor pair in the region of the shielding partition, and

[0058] - introducing the electrically conductive shielding bridge onto and between the conducting elements and non-detachably connecting the exposed shielding sleeve, the exposed inner shielding sleeve and the shielding partition to the electrically conductive shielding bridge.

[0059] It can also be provided in the method that the shielding bridge is introduced onto the conducting element sleeve of the conducting elements and radially completely around the conducting element sleeve.

[0060] It can furthermore be provided that the shielding bridge is composed of a liquid metal that is cast in situ onto and between the conducting elements and solidifies in situ into the shielding bridge.

[0061] The non-detachable connection can be in the form of a material-fit connection, in particular a soldered connection.

[0062] Furthermore, the step of introducing the electrically conductive shielding bridge can comprise inserting the conductive elements with the contact elements into a casting mold, and closing the casting mold and filling the liquid metal material into the casting mold to manufacture the shielding bridge in situ around and between the conductive elements of the shielded electrical connector.

[0063] The application is explained in detail below with the help of examples and with reference to the drawings, in which identical and similar parts are partially provided with the same reference signs, and features of different embodiments can be combined with each other.

[0102] Figures 1 to 6 A first variant of the partial steps of the manufacture of the cable connector 100 is shown. First, Figure 1 The cable end 10 is shown, wherein the end 2a of the conducting elements 2 is exposed. The cable 10 has a cable jacket or cable insulation 4, which provides a touch protection and a comfortable handling of the cable 10. The cable jacket 4 is exposed in a ring-shaped area, where the outer shielding sleeve 20 is exposed. The outer shielding sleeve 20 is embodied, for example, as a wire braid. Adjacently, a section 4a of the cable jacket is retained around the conducting elements 2.

[0103] The conducting elements are combined in pairs, respectively, and have an inner shielding sleeve 24 for each pair of conducting elements 2. In addition, each single one of the conducting elements 2 is provided with a conducting element sleeve 8. The conducting element sleeve 8 electrically insulates the conducting element 2 with respect to its surrounding, i.e. especially with respect to the remaining conducting elements 2. Thus, the conducting element sleeve 8 of each conducting element 2 is typically guided through the entire cable 10 and is only exposed on its end, as shown in Figure 1 .

[0104] As Figure 2As shown, the sealing insert 12 is pushed onto the exposed end 2a of the conductive element 2. The sealing insert 12 has a cable side facing the direction of the inserted cable and a connector side facing the direction of the subsequent connector. Typically, the conductive element is pushed through the sealing insert 12 from the cable side. Alternatively, the contact element 14 may be arranged first on the conductor end 2a, and then the sealing insert 12 may be arranged on the conductor end 2a.

[0105] exist Figure 2 In the example, each sealing insert 12 has two openings, allowing two conductive elements 2 to be inserted into each sealing insert 12. For example, the sealing insert 12 is pushed so far onto the uninsulated conductor end 2a that the sealing insert reaches flush with the conductive element sleeve 8 or partially covers the conductive element sleeve 8. In other words, each sealing insert 12 is sealed together with the conductive element sleeve 8. In this embodiment, four sealing inserts 12 are respectively threaded in pairs onto the eight conductive elements 2 shown, resulting in a ring arrangement of the four sealing inserts 12 on the uninsulated conductor end 2a.

[0106] As in Figure 3 As shown, the contact element 14 is then pushed onto the uninsulated conductor end 2a and mechanically connected to it, for example, by crimping or brazing. Then, the sealing insert 12 is secured to the conductive element 2 from both sides, wherein, for example, on the cable side, the conductive element sleeve 8 abuts against the sealing insert 12, and the contact element 14 abuts against the housing side of the sealing insert 12. The sealing insert 12 can also be secured to the conductive element 2, wherein the sealing insert 12 is partially pushed onto the conductive element sleeve 8 and, for example, initially secured in position by clamping it onto the conductive element sleeve 8. Here, it is sufficient, if only temporarily, to hold the sealing insert 12 in position, i.e., by clamping, as the final and more stable positional fixation of the sealing insert 12 can be performed later, for example, when the shielding bridge 25 is cast.

[0107] Immediately afterwards Figure 3 The housing 30 can be threaded onto the contact element 14. In other words, the contact element 14 is inserted into the housing 30. A sealing insert 12 rests against the shielding partition 35, or more precisely, one sealing insert 12 is present in each shielding segment 33. The shielding partition 35 has a plurality of shielding ribs 34, wherein a shielding segment 33 is formed between every two shielding ribs 34. The shielding segments 33 function as receiving areas for each sealing insert 12.

[0108] Furthermore, the shielding separator 35 has a radial ring 32, wherein the sealing insert 12 is partially located below the radial ring 32, so that the sealing insert 12 together with the radial ring 32 media-sealedly seals the corresponding shielding section 33.

[0109] Subsequently, for example, by means of Figures 7 to 9 As shown, the shielding bridge 25 can be applied to the still exposed conductive element sleeve 8 of the conductive element 2. As... Figure 5 As shown, this forms a shielding bridge 25 that electrically and non-removably, especially in a material-fitting manner, connects the outer shielding sleeve 20, the inner shielding sleeve 24, and the housing 30 to each other.

[0110] like Figure 6 As shown, subsequently, for reasons such as sealing and stress relief, but also for aesthetic reasons, and also to provide touch protection, a flexible sheath 50 is mounted onto the connector 100. Thus, the commercial form of the connector 100 is finally obtained.

[0111] Figures 7 to 9 The fabrication of the shielding bridge 25 in the mold 300 is shown. Figure 7 First, an empty mold 300 is shown, which has a filling opening for the material (e.g., a low-melting-point metal alloy) used to manufacture the shielding bridge 25. Additionally, the mold 300 has a connector receiving opening 304 into which the connector 100 can be inserted. Typically, the mold 300 is configured as two halves that can be coupled and closed in pairs, wherein... Figures 7 to 9 Only one half of the mold is shown in the image to facilitate understanding of the structure.

[0112] Figure 8 A mold 300 in which a connector 100 is embedded is shown, wherein the portion to be cast is open, and the shielding bridge is to be cast onto the exposed conductive element sleeve 8, sealing insert 12, shielding separator 35 and outer shielding sleeve 20.

[0113] Figure 9 A mold 300 in which connector 100 is embedded is shown, wherein shielding bridge 25 is cast and hardened or cooled. Electrical connections from housing 30 to outer shielding sleeve 20 and inner shielding sleeve 24 are made via shielding bridge 25.

[0114] Figure 10 A detailed top view of the housing 30 is shown, which has a sealing ring 28, a shielding separator 35 with radial rings 32, and shielding ribs 34. The sealing ring 28 serves as a seal in the mold, particularly when the shielding bridge 25 is cast while still in a liquid state, i.e., especially liquid metal. Furthermore, on the later-completed plug connector 100, it can be used together with the end encapsulation, i.e., the flexible sheath 50, as a sealing element to prevent moisture intrusion. The ends of contact sleeves 16 are inserted into the shielding section 33, each contact sleeve 16 having two through holes 161, 162 (see...). Figure 13). The sealing insert 12 is installed in the remaining area of the shielding section 33, see Figure 18 Finally, the housing part 30 has a thread 40 in order to connect the housing part 30 with another connection piece.

[0115] The shielding partition 35 has an inner hollow portion 38 in which the coding projection 36 is arranged. The coding projection 36 indicates a correct connection of the conducting elements 2 on the respective shielding section 33 of the housing part 30.

[0116] Figure 11 A housing part 30 is shown which has one shielding partition 35 and four shielding ribs 34. In this example, no contact sleeve 16 is provided or required. This form of the housing part 30 can be provided, for example, when an inner thread is provided on the distal end of the housing part 30 or a different connection technology than the thread 40 is provided. For example, Figure 11 Embodiments of the Figure 10 are shown in detail.

[0117] Figure 12 A further plug connector 100 is shown in a partially installed state, wherein the cable end 10 is deinsulated from the cable insulation 4 and the conductor end 2 is exposed. The outer shielding sleeve 20 can be contacted between the insulation 4 and the section 4a of the cable insulation in any case, but also on the end section of the cable insulation 4. The deinsulated conductor end 2a (see, for example Figure 1 ) is already equipped with the contact elements 14, which are pushed onto the conducting element sleeve 8 or are installed in such a way that a small free area of the conducting element 2 remains between the contact elements 14 and the conducting element sleeve 8.

[0118] It is particularly advantageous that the contact sleeve 16 can be pushed onto the contact elements 14, which can accommodate two contact elements 14 each in pairs. The contact sleeve 16 is thus pushed onto the contact elements 14 in such a way that the contact elements 14 are pushed into the through-holes 161, 162 and the contact sleeve 16 is guided to the conducting element sleeve 8. For better insulation, the contact sleeve 16 furthermore has an insulation flange 163 between the two through-holes 161, 162. Finally, the contact sleeve 16 also covers a large part of the contact elements 14 by means of the sleeve bulge 164.

[0119] Figure 14 A plug connector 30 is shown in a partially installed state, equipped with a contact sleeve 16 as described in Figure 13 , wherein every two conducting elements 2 are pushed into one contact sleeve 16. Since Figure 14 the cable 10 of the embodiment has eight conducting elements 2, four contact sleeves 16 are provided, into which two conducting elements 2 are inserted each.

[0120] Figure 15 against Figure 14 An alternative embodiment is shown in which the conductive elements 2 are twisted or wrapped around each other in pairs in the exposed areas, a so-called "wound-paired configuration". The conductive elements 2, twisted around each other in the exposed areas, are inserted in pairs into the contact sleeve 16.

[0121] Figure 16 It shows Figure 14 and Figure 15 Another alternative implementation, the Figure 14 and Figure 15 This configuration can also be layered if necessary, among which Figure 16 The vacated area contains a second conductive element sleeve 9, into which conductive elements 2, arranged in pairs, are introduced in pairs. The second conductive element sleeve 9 is, in particular, a section of shrink tubing or electrical insulation material.

[0122] Figure 17 The attached housing part 30 is now shown. Figure 14 In one embodiment, the housing 30 is pushed from the front onto the conductive element 2 or the contact element 14, such that the contact sleeve 16 is positioned at its end or through the through holes 161, 162 within the corresponding shielding section 33, for example, below the radial ring 32. If necessary, a short section of the uninsulated conductor end 2a may also extend from the contact sleeve 16. This is advantageously not critical, as these areas will also be covered.

[0123] Figure 18 An embodiment of a sealing insert 12 for insertion into a shielding section 33 of a shielding separator 35 is shown. The sealing insert 12 has first and second through holes 121, 122 for the conductive element 2 to pass through. (The last sentence appears to be incomplete and possibly refers to a different embodiment.) Figure 18 In the illustrated embodiment, there are two through-holes 121 and 122, allowing a pair of conductive elements 2 to pass through and be guided by the sealing insert 12. In other words, the sealing insert 12 provides a medium-sealed seal for the pair of conductive elements 2. Figure 19 As shown, the plug connector 100 in its mounting configuration can now be equipped with a shield bridge 25. Advantageously, the shield bridge 25 is led to the sealing ring 28 in the region of the outer shield sleeve 20 via a segment 4a of the cable insulation, the exposed conductive element sleeve 8, the sealing insert 12, and the shield separator 35. This can be achieved, for example, by means of... Figure 7 The mold shown is used for execution.

[0124] Figure 20A plug connector 100 is shown, into which a shielding bridge 25 is introduced, which is used to make a gapless shielding sleeve, in particular from the outer shielding sleeve to the sealing ring 28, in which the inner shielding sleeve 24 is also contacted and also contacted internally between the conducting elements 2 by means of the shielding partition 35. Thus, the intermediate shielding between the conducting elements 2, in particular between the pairs of conducting elements 2 composed of conducting elements 2 and the remaining conducting elements 2, is also maintained throughout the length of the plug connector 100 and throughout the entire extension of the conducting elements 2 from the plug connector 100 into the cable 10. Since the material of the shielding bridge 25 flows in a favorable manner between the conducting elements 2 in that the shielding bridge 25 is cast directly onto the conducting element sleeve 8 and flows there between the conducting elements 8, 2. In other words, with the applied shielding bridge 25, each conducting element 2 is radially encompassed overall by the material of the shielding bridge 25, in particular thus with respect to the other conducting elements 2 of the other conducting element pairs. Furthermore, the shielding bridge 25 is also contacted with the shielding partition 35 and in particular with all the shielding ribs 34 of the shielding partition 35. It is particularly advantageous that a material-fit connection of the shielding bridge 25 to the shielding ribs 34 of the shielding partition 35 is achieved here. It is likewise preferred that this material-fit contact can also be produced with the outer shielding sleeve 20 and the inner shielding sleeve 24, so that the shielding bridge 25 provides a material-fit connection bridge from the shielding partition 35 via the shielding bridge 25 up to the outer shielding sleeve 20 or the inner shielding sleeve 24.

[0125] Finally, Figure 21 A connector according to Figure 20 is shown, in which a protective sleeve 50 is applied to the region of the shielding bridge 25, for example by injection molding encapsulation, as is common on the market. If necessary, the protective sleeve 50 can be crimped or crimped in order to achieve a position fixation or stress relief and / or a medium tightness on the cable 10.

[0126] Figure 22 A top view of the plug connector 100 in the completed installed state is shown, in which the sectional lines A-A and B-B represent the views of Figure 23 , Figure 24 and Figure 25 . Figure 23 A longitudinal section of the plug connector as explained along the line A-A is shown using Figure 22 . Figure 23 The plug connector 100 shown is shown in the completed installed state, in which the protective sleeve has also been applied. In Figure 23In the longitudinal section, the outline of the shielding bridge 25 is clearly visible. This outline surrounds the conductive element 2, extends between the conductive elements 2, and continues to the segment 4a of the cable insulation 4. The shielding bridge 25 contacts the housing members 30 and 32 in a material-fitting manner, thus completely establishing a shielding bridge. On the inner side, the shielding bridge 25 contacts the shielding separator 35.

[0127] The cable has a cable core 5, which is used, for example, to improve the symmetry of the cable (due to HF characteristics) and / or to strengthen the cable. In the example shown here, the cable has two conductive elements 2, each surrounded by a conductive element sleeve 8. An inner shielding sleeve 24 surrounds each conductive element 2. Furthermore, an outer shielding sleeve 20 shields the cable as a whole relative to the environment. The cable 10 has an external cable insulation portion 4.

[0128] The conductive element 2 is inserted into and fixed therein at its deinsulated conductor end 2a. A contact sleeve 16 is arranged around the contact element 14 to accommodate the contact element 14. A sealing insert 12 is provided in the area of ​​the shielding separator 35 to seal the contact sleeve 16 or the plug-side medium to the cable side of the shielding bridge 25 or the shielding separator. Figure 23 The cable 10 shown may also have multiple conductive elements 2, which in Figure 23 The image is not shown due to the selected perspective.

[0129] Figure 24 Another example of a fully assembled plug connector 100 is shown, wherein a plurality of eight conductive elements 2 in the housing 30 contact contact elements 14. Two conductive elements 2 are shown in cross-sectional outline, for example, each surrounded by a conductive element sleeve 8. A shielding bridge 25 is cast in situ from a cast metal material, particularly a low-melting-point metal alloy, onto the conductive elements 2 or their conductive element sleeves 8, such that the shielding bridge 25 preferably extends radially integrally around each of the conductive elements 2 on all sides. Furthermore, the shielding bridge 25 contacts the outer shielding sleeve 20 and the inner shielding sleeve 24, such that both, or all, of the shielding sleeves 20, 24 contact the shielding contacts 28, 35 of the housing 30 of the plug connector 100. Here, the conductor shielding between the pairs of conductive elements 2 is maintained completely and without gaps.

[0130] Figure 25 It shows along Figure 22 The radial section of section AA is shown in the figure. In the region of the shielding separator 35, the conductive element 2 passes through four sealing inserts 12, one of which is arranged in each shielding segment 33. The coding device 36 indicates the correct orientation of the conductive element 2 on the housing 30 during assembly.

[0131] Figure 26 An embodiment of the housing part 30 of the plug connector 100 is shown, in which the contact sleeve 16 is located in the region of the shield section 33 of the shield partition 35. The contact sleeve 16 extends through the housing part 30 up to a short distance in front of the plug face 18 (see Figure 31 ). For example, the housing part 30 can be provided in this partially mounted form together with the preassembled contact sleeve 16 for further assembly of the plug connector, so that the conductive elements 2 provided with contact elements can be introduced into the contact sleeve 16 and thus also into the housing part 30.

[0132] Figure 27 A side view of the plug connector 100 in the completed assembled state is shown, in which the Figure 27a , Figure 27b , Figure 27c and Figure 30 cross-sectional and front views E shown below are shown along the section lines A, B and D.

[0133] Figure 27a A radial section along the section line A-A shown in Figure 27 is shown, namely in the region of the shield bridge 25, which individually radially completely surrounds all conductive elements 2, namely also each pair of conductive elements from one another, and the pairs of conductive elements 2 relative to the other pairs of conductive elements 2. In this region, the conductive elements 2 are each electrically separated by the conductive element sleeve 8. The conductive elements 2 are thus not guided by the electrical shield insert 25.

[0134] Figure 27b An embodiment is shown instead of Figure 27a , which likewise shows a radial section along the section line B-B as shown in Figure 27 in the region of the shield bridge 25 of the plug connector 100. Each pair of conductive elements 2 is additionally surrounded by a second conductive element sleeve 9. The conductive elements 2 are thus first radially completely surrounded by the conductive element sleeve 8 from the inside, are radially completely surrounded thereon by the second conductive element sleeve 9, and are radially completely surrounded thereon preferably by the shield bridge 25 from the outside. According to the embodiment, the region between a pair of conductive elements 2, namely the region inside the second conductive element sleeve 9, is not filled by the shield bridge 25. It is nevertheless clear that each conductive element 2 is also preferably radially completely surrounded by the shield bridge 25 outwardly in this case. For example, in Figure 27bThe conductive element 2 in the upper left corner is adjacent to its counterpart which is arranged in the same second conductive element sleeve 9. This counterpart lies on an imaginary straight line (Fluchtlinie) from the conductive element 2 to the next pair of conductive elements 2. Despite this, there is material of the shielding bridge 25 between this conductive element 2 and the next pair of conductive elements 2 which is surrounded by a further second conductive element sleeve 9. Thus, in all radial directions, material of the shielding bridge 25 is arranged around each conductive element 2. It is particularly important here that material of the shielding bridge 25 is arranged between each pair of conductive elements 2 which is surrounded by a common second conductive element sleeve 9 towards the other pair of conductive elements 2 which is surrounded by a further second conductive element sleeve 9 and thus causes a shielding effect between the pairs of conductive elements 2. Thus, the pairs of conductive elements 2 are also shielded from one another.

[0135] Figure 27c A radial section along the section line D-D shown in Figure 27 is shown, namely in the region of the cable 10. Each pair of conductive elements 2 is shielded from the remaining pairs of conductive elements 2 by an inner shielding sleeve 24. Furthermore, an outer shielding sleeve 20 also surrounds all of the conductive elements 2. The conductor pairs which are respectively embedded in the inner shielding sleeve 24 are embedded in a cable filling material, such as cable rubber, and are thus fixed. The inner shielding sleeve 24 can be, for example, a thin aluminium foil or a plastic film on which aluminium or another metallic material is evaporated. Here, a metallic material is preferred for the insulation. When the inner shielding sleeve 24 and / or the outer shielding sleeve 20 is made of or comprises a metallic material, then a connection to the material of the shielding bridge 25 can be produced.

[0136] Figure 28 A further alternative embodiment of the partially assembled plug connector 100 is shown, in which the conductive elements 2 are arranged twisted in a region which is also exposed and are inserted into the contact sleeve 16.

[0137] Figure 29 A further alternative embodiment of the partially assembled plug connector 100 is shown, in which the respective pairs made up of conductive elements 2 are each provided with a second conductive element sleeve 9, such as a shrinkable hose.

[0138] Figure 30 A front view of the plug connector 100 is shown along the section line E-E as in Figure 27 . This radial section is arranged within the housing part 30, so that it passes through the contact sleeve 16 and the shielding partition 35. The contact elements 14 are arranged in the contact sleeve 16. Furthermore, Figure 30 a section line C1-C1 is shown, which represents a longitudinal section of Figure 31 .

[0139] Figure 31 A radial section along the section line D-D shown in Figure 30The section line Cl-Cl runs through a longitudinal section of the plug connector 100 in the completed assembly. The cable 10 has a plurality of conductor elements 2 which are inserted into the contact elements 14 in the housing part 30. The shielding bridge 25 surrounds the conductor elements 2, preferably radially overall, i.e. also between the conductor elements 2, in the connection region between the cable 10 and the housing part 30. The shielding bridge 25 here extends from the exposed region between the cable insulation 4a and the cable insulation 4 on the cable side up to the contact ring 28 of the housing part on the housing side and here contacts the shielding partition 35 as well as the inner shielding sleeve 24 and the outer shielding sleeve 20.

[0140] Figure 32 An embodiment of the plug connector 100 in the completed assembly is shown, which is screwed into a mounting part 44 with a circuit board or mounting plate 42.

[0141] To this end, Figure 33 A top view of the plug face 18b of the mounting part 44 is shown. The plug face 18b is provided on the circuit board or mounting plate 42.

[0142] Finally, Figure 34 A longitudinal section of the connector 100 according to Figure 32 with a mounted mounting part 44 thereon is shown.

[0143] The invention thus describes a plug connector 100 in which a complete shielding of the individual conductor elements 2 of the cable 10 can be achieved not only by the outer shielding 20 but also a mutual shielding between at least the pairs of conductor elements 2 in a particularly economical and effective manner. Here, the shielding bridge is introduced over the exposed region between the cable 10 and the housing part 30 such that the shielding bridge 25 also extends between the individual conductor elements 2 or in any case between the pairs consisting of conductor elements 2, such that each conductor element 2 is radially overall surrounded by the material of the shielding bridge 25, i.e. in particular radially overall by the shielding bridge 25. Thus, a gapless and complete shielding can be achieved both towards the outside by the outer shielding sleeve 20 and also between the conductor elements 2 towards the inner shielding sleeve 24 of the respective pair of conductor elements, as well as towards the shielding partition 35 and the housing parts 30, 32. Here, a one-piece shielding bridge is used which also produces a non-detachable connection from the shielding elements 20, 24 of the cable 10 up to the contact elements 28, 35 of the housing part 30. The non-detachable connection provided by the shielding bridge 25 here is in particular a material-fit connection, for example by means of a soldering method. The shielding bridge 25 described is preferably cast in situ directly and immediately from a metallic material onto the conductor element sleeve 8 or the second conductor element sleeve 9 in the annular region shown.

[0144] It is clear to the person skilled in the art that the embodiments described above are to be understood as examples and that the application is not restricted to these embodiments, but can vary in a multiplicity of ways without deviating from the scope of protection of the claims. It can furthermore be seen that the features described, independently of whether they are disclosed in the description, the claims, the drawings or elsewhere, alone define individual essential components of the application, even if they are jointly described with other features. In all the drawings, identical reference signs denote identical objects, so that the description of an object, possibly mentioned only in one drawing or in any case not mentioned for all the drawings, can also be transferred to the drawings in which it is not described in detail.
