Shielded electrical connector

Field of invention

The present disclosure relates to a shielded electrical connector and a method of making a shielded electrical connector.

Background and general description of the invention

Methods are already known for providing cables with a shield when they are connected to a connector. For example, solutions are known in which a crimp sleeve and a union nut are used, see German patent DE 196 13 228 B4.

In another variant, it is proposed, for example, in US Pat.

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

Document WO 2016 135 170 A1 from the applicant describes a procedure in which shielding is produced by a metal casting process. The present application can be seen as a further development of the aforementioned patent application, which is why WO 2016 135 170 A1 is incorporated by reference.

In addition to the disadvantages of the prior art 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, in particular due to the temperature and aging of the materials used.

In addition, all of the previously known methods merely offer a connection between the outermost shielding sleeve of the cable and the connector.

According to the invention, however, cables can be used in which conductors that are arranged in the cable can or should have supplementary cable shielding. To avoid crosstalk of signals from the different conductors in each other reduce or prevent, it can therefore even be advantageous or desired if the conductor shielding, which shields individual conductors or a subset of the conductors of the cable from one another, can further or continuously achieve the shielding effect in the area of the connector, so that there is no crosstalk between the conductors. This is not provided or not possible in the previously known methods.

The invention is based on the object of creating a shielded electrical connector with a good shield connection between a shielded electrical line and a shielded connector.

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 during the life of the connector.

The shielded electrical connector can therefore advantageously be produced simply and largely by machine and particularly preferably has as few individual parts as possible in order to further simplify assembly.

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

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

The shielded electrical connector comprises a plurality of line elements, that is to say at least two line elements which belong to a line or the plug connector. For example, the line elements are part of an electrical cable, which are to be connected to contact elements of a 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, each line element typically having its own line element sheath. The plurality of line element sheaths are therefore at least two line element sheaths. The conduit element sheaths can be, for example, a plastic sheathing, rubber sheathing or any type of wire insulation. A shrink tube or a conduit element sheath that is subsequently applied during the assembly of the plug connector can also be considered.

Furthermore, an outer shielding sleeve is included, which surrounds the plurality of line elements at least partially or at least in areas. Typically, the outer shielding sheath completely surrounds the line elements in the region of the unopened cable, that is to say continuously from a first end of the cable to a second end of the cable. The outer shielding sheath can therefore be used to achieve a shielding effect along the entire cable, and in a preferred embodiment the shielding sheath can also be grounded to the connector (s) at at least one end of the cable, for example to a contact ring of a housing part. In other words, the outer shielding sheath encloses all of the line elements together, so that the line elements are arranged together on an inside of the outer shielding sheath and are shielded from the environment by means of the outer shielding sheath.

In the area of the connection between the cable and the connector, the outer shielding sleeve is exposed in order to reach the line elements for the purpose of making contact with contact elements. The exposure is preferably done by machine, so that in each case a constant ring area of the outer shielding sleeve is exposed, for example at one end of the cable.

Furthermore, at least one inner shielding sheath is included, which together at least partially or at least regionally surrounds a subset of the line elements for shielding against remaining line elements. For example, the line elements can be combined in pairs and provided in pairs with a respective inner shielding sleeve. In one example, the cable comprises a total of eight line elements, each of which is surrounded in pairs by an inner shielding sheath, so that in this example four inner shielding shells are included, which are once again surrounded by the outer shielding sheath. The subset of the 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 only assigned to exactly one subset. In a cable that comprises different line elements, it can then also be provided that only the subset of the line elements has the inner shielding, for example, to add current-carrying wires from signal-carrying wires in a common cable shield. In a preferred case, a first subset of line elements, for example carrying signals, is enveloped by means of a first inner shielding sleeve and a second subset of line elements, for example also carrying signals, is separately enveloped by means of a second inner shielding sleeve.

A connector housing is also included, in which contact can be made with the plurality of line elements, in particular with contact elements. Typically, the connector housing also includes a plug face for connecting to a further line part or for making contact with the line elements with a next assembly.

The shielded electrical connector further comprises a shield divider which forms at least two shield sectors. For example, the screen divider has at least two screen bars, the radial area between two screen bars forming one of the screen sectors. At least one line element can be passed through a shielding sector. One of the subsets of the line elements is preferably passed through a shielding sector, namely a subset in which the individual line elements of this subset do not have to be shielded from one another, but only from the other line elements of the cable.

Furthermore, at least one sealing insert is included in order to seal a cable side in the region of the screen divider from a plug side. In other words, the sealing inserts are provided in order to provide a fluid-tight barrier so that no fluid exchange can take place from the cable side to the plug side and / or vice versa. In other words, the sealing insert or the sealing inserts provide a fluid barrier in the axial direction, so that an exchange of fluid between the plug 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.

The line elements are either passed through the sealing inserts or the sealing inserts are applied to the respective line element (s), e.g. sprayed on or molded in a shaping process. For example, several sealing inserts are provided for arrangement or for inserting or injecting, pouring each into a shield sector, in particular one sealing insert in each shield sector.

Furthermore, an electrically conductive shielding bridge is included for the electrical, in particular non-detachable, connection of the outer shielding shell at least to the one or more inner shielding covers and the screen divider. In other words, the electrically conductive shielding bridge or the shielding insert provides an electrical bridge which connects the outer shielding shell to the inner shielding shell and the shield divider with the lowest possible electrical resistance.

The electrically conductive shielding insert or the electrically conductive shielding bridge can establish a non-detachable connection between both the outer shielding sleeve, the inner shielding sleeves and the screen divider up to the connector housing, the electrically conductive shielding bridge preferably being arranged in one piece around the conductor element sleeves. In this case, the electrically conductive shielding bridge can particularly preferably enclose the line element sheaths radially on all sides. This means that the electrically conductive shielding bridge is also arranged between the line elements. In other words, the shielding bridge also ensures through-contacting of the inner shielding sheaths with the shield divider and the outer shielding sheath, as a result of which the inner shielding effect or the intermediate conductor shielding, in particular, is fully and / or completely maintained. 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, with the internal shielding effect between the subsets of line elements being maintained remains, and in particular without gaps.

If the line elements are each provided separately with line element sheaths, it is particularly advantageous if the electrically conductive shielding bridge is arranged between each line element, that is, between all line elements. In other words, the electrically conductive shielding bridge encloses each line element radially on all sides. In the event that 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, the electrically conductive shielding bridge also encloses all line element sheaths radially on all sides, with the intermediate area between the Pair of line elements from the electrically conductive shielding bridge remains free. In other words, the interior of the second line element sheath is not filled with the electrically conductive shielding bridge in this case, but rather is arranged around the respective second line element sheaths. Also in In this case, the electrically conductive shielding bridge surrounds the pair of two line elements with a second line element shell and thus also each line element radially on all sides.

In other words, it is a practicable example that each line element has a separate line element sheath, that is to say in particular a core insulation. The electrically conductive shielding bridge is then introduced in such a way that the shielding bridge surrounds the line elements on all sides, i.e. in particular surrounds each individual line element radially on all sides, and thus preferably extends between the individual line elements, for example, runs in the liquid state between the line elements and extends there like that distributed so that a coherent component is produced as an electrically conductive shielding bridge. The line element sheaths are prepared to withstand the thermal load when the shielding bridge is introduced, so that no electrical contact occurs between the line elements and the shielding bridge. For example, the line 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 line elements and the shielding bridge. An electrical connection between the line elements and the electrically conductive shielding bridge is therefore not provided or is not present in the area in which the shielding bridge is inserted. If necessary, one of the line elements, in particular a ground connection, can be in contact with the shielding bridge in a special embodiment in the plug; This should not be ruled out. However, the preferred case is that there is no electrical contact between the line elements and the shielding bridge, but the shielding bridge effects the electrical shielding of the line elements from one another as well as the electrical shielding of the line elements from the environment.

The electrically conductive shielding bridge is thus arranged around the line elements and also between the line elements and forms a one-piece, that is to say monolithically constructed component as a shielding bridge. The one-piece, that is to say monolithically constructed, electrically conductive shielding bridge, as a continuous component, directly and immediately connects the outer shielding shell with the inner shielding shell (s) and the shield divider. This establishes a solid and secure electrical connection between the three aforementioned components, the outer shielding shell, the inner shielding shell (s) and the shield divider, which is in particular seamlessly connected by means of the shielding bridge between and around the line elements around can be provided. The secure contacting of all the aforementioned components with one another can ensure a simplification of the manufacturing process, since the electrical contact may no longer have to be checked. The one-piece component of the shielding bridge, which connects all of the aforementioned components electrically to one another, in particular in a fixed and melting manner, may have a lower electrical resistance in comparison to a multi-part shielding. A multi-part electrical shielding may also require additional work steps during manufacture. On the other hand, the shielding bridge, which is in particular completely constructed, can improve the signal quality and / or reduce the signal attenuation, particularly in high-frequency applications (ie in RF technology) and / or in an application in which external interference fields are expected.

It is therefore a special feature that can be implemented with the shielding bridge of the present invention that the outer shield (in particular of the cable), the inner shield (s) (in particular two line elements each) and the shield divider in a monolithic construction are electrically are connected to each other. This avoids, reduces or prevents potential defects in the shield. In contrast to a potentially multi-part shielding bridge, there are no longer any “jump points” in which a gapless bond is also dependent, for example, on the bonding to the intermediate part and the possibility of providing a shielding bridge without any gaps in such a case. In the case of a multi-part shielding bridge, for example, in the event of vibrations during operation or in the event of a shock, the various parts may detach from one another in such a way that only an inadequate contact or an interrupting contact can be established in the shielding effect. These problems can be eliminated or improved with the monolithic shielding bridge presented here. The electrical contacting of the three shielding elements (outer shielding, inner shielding (s), shield divider) to one another is thus ensured or improved due to the monolithic structure of the shielding bridge, and at the same time shielding of the line elements from all sides and as fully as possible in the area in which the Shielding bridge is arranged.

It can also be provided that the line elements are stripped on a longer piece, for example in the axial direction out of the shielding sectors in the direction of the cable, and initially one on the stripped ends of the line elements Cover is applied, for example an injected plastic. The electrically conductive shielding insert can also be applied to this cover.

It is preferred that the line elements are stripped only up to the sealing elements and that the line element sheaths are intact in the area on which in particular the electrically conductive shielding bridge is poured and thus the shielding bridge is, for example, cast directly onto the line element sheaths. The material of the shielding bridge thus also gets between the subsets of the line elements, preferably between the individual line elements.

With regard to the shielding effect, it can be irrelevant whether the line elements arranged together in a pair or a subset do not have any shielding from one another with the electrically conductive shielding bridge, but the shielding purpose can already be achieved when the second line element shell that surrounds the pair of line elements , is radially surrounded on all sides by the electrically conductive shielding bridge. It is preferred that all line 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 line element sheaths and / or the second line element sheaths.

Since the electrically conductive shielding bridge particularly preferably forms a non-detachable connection between the outer shielding shell and that in the inner shielding sheaths and the shield divider, the electrically conductive shielding bridge can also absorb mechanical forces between the outer shielding shell on the one hand and the shield divider on the other hand, in particular tensile forces. The electrically conductive shielding bridge is preferably materially connected to both the outer shielding shell, the inner shielding shells and the shield divider. The electrically conductive shielding bridge forms, in particular, complete shielding and mechanical anchoring of the cable on the connector.

The line elements either belong to a line or a plug connector or preferably contact a line with a plug connector.

The line elements are preferably present in pairs of at least two line elements per pair, the inner shielding sleeves being designed to shield the line elements from one another in pairs. The electrically conductive shielding bridge preferably produces a cohesive bond with the outer shielding shell, the inner shielding covers and the shield divider, so that a material bond is formed from the shielding covers to the shield divider via the electrically conductive shielding bridge.

The shielding bridge preferably also extends between the line elements, the shielding bridge preferably also closing the area between the line elements so that the individual line elements are shielded from one another on all sides

The shielding bridge is preferably made of a metal material. The shielding bridge can be cast around the line element sheaths by means of a metal casting process. The shielding bridge is preferably cast in situ around the line element sheaths and between the line elements, so that it encloses the line elements radially on all sides, in particular in an annular region of the cable length. In other words, the shielding bridge can be inserted without gaps around and between the line element sheaths and thus the line elements, for example, it can be cast in situ onto the partially assembled connector by means of a metal casting process in order to achieve the seamless shielding of the connector.

The shielding bridge is preferably designed to anchor the inner shielding sheaths and the outer shielding sheath on the screen divider. In other words, a force from the cable to the connector and vice versa can also be diverted via the shielding bridge. 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 on the connector.

The screen divider is electrically connected to the connector housing, in particular manufactured in one piece with the connector housing. For example, the connector housing is made of a metal material such as die-cast zinc, and the screen divider is die-cast in one piece with the connector housing together.

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

The shielding bridge can also be made of an electrically conductive plastic material or another electrically conductive material in order to achieve the shielding effect.

The electrically conductive plastic material can also produce a non-releasable connection between the outer shielding shell, the inner shielding shell (s) and the shield divider, for example by means of an adhesive effect. Finally, the shielding bridge can also be prepared, for example, in such a way that it is attached to the outer shielding shell, inner shielding sheaths and shield dividers, for example crimped or soldered, in order to establish the electrical, and in particular non-detachable, connection between them.

In order to improve the thermal insulation of the line element or especially the line element sheaths and, if necessary, to ensure improved electrical insulation between the line elements and the shielding bridge and / or improved RF properties, second line element sheaths can be provided which jointly enclose at least two line elements, with the electrically conductive shielding bridge encloses the second line element sheaths in particular radially on all sides. In other words, a further sheath is arranged on the line element sheaths, for example in the form of shrink tubing or suitable plastic material, for example also poured on, in order to protect the line element sheaths even better against the thermal effects of the liquid shielding bridge during the production of the shielding bridge.

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

A subset or a pair of two line elements is preferably passed through each screen sector, so that the screen divider shields the subsets of line elements from one another and each screen web of the screen divider is electrically and non-detachably connected to the screening bridge, i.e. in particular with a material bond.

The screen divider can have an inner hollow element, for example to increase the stability or to reduce the material requirement for producing the plug connector or the screen divider. A coding device can preferably be arranged in the hollow element of the screen divider, the coding device indicating that the line elements are arranged in the correct direction in the connector. In other words, for example, a simple coding tab can indicate to the fitter in which orientation the connector housing is to be arranged in relation to the cables. For example, the conduit element sleeve of each conduit element can have a specific color, so that the correct assembly in the correct position of the conduit elements or the plug-in contacts is made possible in a simple manner using the colors together with the coding device. During assembly, attention no longer has to be paid to the mating face, since during assembly 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. so that the directionally correct assembly of the line elements in the connector housing can be carried out without errors.

By means of the sealing inserts, the side from which the cable is led to the connector housing, that is to say the cable side, can be sealed in a fluid-tight manner from the inner region of the connector housing, that is to say the connector side. The sealing inserts are prepared, preferably to seal each shield sector separately. A plurality of sealing inserts are therefore preferably arranged radially around the screen divider so that, for example, a sealing insert is arranged in each screen sector and each sealing insert seals one screen sector in a fluid-tight manner.

These sealing inserts are advantageous if - as in one example of the present invention - the shielding bridge is introduced in molten form into the connector or onto the cable in order to predefine the area of extent of the shielding bridge in the direction of a connector housing. The molten material of the shielding bridge preferably flows up to the respective sealing insert, but not further. At the same time, the sealing insert can be designed to effectively prevent electrical contact between the shielding bridge and the line element, even in the stripped area of the line element. For this purpose, the line element can be inserted into the sealing insert to such an extent that the stripped area is completely covered by the sealing insert.

The connector housing can furthermore have a radial shield which at least partially encloses the shield divider on the outside. The sealing inserts can be arranged between the screen divider and the radial screen and insulate the cable side from the plug side electrically and optionally in a fluid-tight manner in a ring area. In other words, the screen divider and the radial screen together in each screen sector can form a pocket, so to speak, into which the sealing inserts are at least partially inserted. The sealing inserts can therefore be inserted into the pocket formed in the respective umbrella sector or filled there.

The sealing inserts can be made of plastic. A sealing insert can have passage openings for passing through or pushing through the wire ends of the line elements or the contact elements. The sealing insert can for example have one, two or more than two such passage openings. A sealing insert suitably has as many passage openings as there are line elements to be guided into a shielding sector in order to improve the sealing effect. Sealing inserts can also be made from casting compound, which is cast in situ around at least two of the line elements in order to seal the cable side from the plug side. The potting compound can be epoxy resin or an adhesive material.

The sealing inserts can be produced with a shaping process, so that a plastic part in a shape such as a compression mold is already produced before assembly in the connector and is inserted into the connector. For example, the sealing insert can be produced by pressing or squeezing the line element sheaths into the respective shielding sector and the line element sheaths thus closing the respective shielding sector and providing a tight or fluid-tight seal between the cable side and the plug side.

In accordance with the invention, a method for manufacturing a shielded electrical connector is also provided. The procedure consists of the following steps:

- Freeing the outer shielding sheath, the inner shielding sheaths and the conduit element sheaths at one end of the cable,

- Connect one of the line elements with one contact element each,

- Arranging the line elements and / or the contact elements in pairs as a pair of conductors each in a shield sector of the shield divider,

- Attaching or applying the sealing inserts to or around each pair of conductors in the area of the screen divider, and - Introduction of the electrically conductive shielding bridge on and between the line elements and thereby non-detachable connection of the exposed shielding sleeve, the exposed inner shielding sleeves and the screen divider with the electrically conductive shielding bridge.

In the method it can further be provided that the shielding bridge is introduced on and radially on all sides around the line element sheaths of the line elements.

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.

The non-releasable connection can be an integral connection, in particular in the form of a soldered connection.

Furthermore, the step of introducing the electrically conductive shielding bridge can include inserting the line elements with contact elements in a casting mold and closing the casting mold and pouring liquid metal material into the casting mold to produce the shielding bridge in situ around and between the line elements of the shielded electrical connector.

The invention is explained in more detail below using exemplary embodiments and with reference to the figures, with identical and similar elements in some cases being provided with the same reference numerals and the features of the various exemplary embodiments being able to be combined with one another.

Detailed description of the invention

FIGS. 1 to 6 show a first variant of partial steps in the production of a cable connector 100. FIG. 1 initially shows a cable end 10 in which the ends 2a of line elements 2 are exposed. The cable 10 has a cable sheathing or cable insulation 4, which provides protection against contact and a comfortable handling of the cable 10. The cable sheathing 4 is exposed in a ring area on which the outer shielding sheath 20 is exposed. For example, the outer shielding sleeve 20 is designed as a wire mesh. A section 4a of the cable sheathing around the line elements 2 remains adjacent.

The line elements are each combined in pairs and each pair of line elements 2 have inner shielding sleeves 24. Each individual line element 2 is also provided with a line element sheath 8. The line element sheath 8 provides the electrical insulation of the line element 2 from its surroundings, i.e. in particular from the other line elements 2. Accordingly, the line element sheath 8 of each line element 2 is typically passed through the entire cable 10 and only exposed at its ends, as shown in FIG .

As shown in FIG. 2, sealing inserts 12 are pushed onto the exposed ends 2a of the line elements 2. The sealing inserts 12 have a cable side which points in the direction of the inserted cable and a connector side which points in the direction of the later connector. Typically, the line elements are pushed through the sealing insert 12 from the cable side. The contact elements 14 can also first be arranged on the conductor ends 2a and then the sealing inserts 12.

In the example of FIG. 2, each sealing insert 12 has two passage openings, so that two line elements 2 can be introduced into each sealing insert 12. For example, the sealing inserts 12 are pushed so far onto the stripped conductor ends 2a until they are flush with the line element sheaths 8 or that the Sealing inserts 12 partially cover the line element sheaths 8. In other words, each sealing insert 12 seals together with the conduit element shells 8. In this example, four sealing inserts 12 are threaded onto the eight line elements 2 shown in pairs, so that an annular arrangement of the four sealing inserts 12 at the stripped conductor end 2a results.

As shown in FIG. 3, 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 on or the like. The sealing inserts 12 are then fixed on the line elements 2 from both sides, for example the line element sheaths 8 abut the sealing inserts 12 on the cable side and the contact elements 14 abut on the housing side of the sealing inserts 12. The sealing inserts 12 can also be fixed on the line elements 2, the sealing inserts 12 being partially pushed onto the line element sheaths 8 and initially fixed in terms of their position, for example by means of clamping on the line element sheaths 8. It can be sufficient that the sealing inserts 12 are initially only sufficiently or provisionally held in terms of position, i.e. clamped, for example, since the sealing inserts 12 can only be finally and more stably fixed in position, for example, if the shielding bridge 25 is subsequently poured on will.

Subsequently to FIG. 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 come to rest on the screen divider 35, namely a sealing insert 12 in each screen sector 33. The screen divider 35 has a plurality of screen webs 34, a screen sector 33 being formed between two screen webs 34. A shield sector 33 is, as it were, a receiving area for a sealing insert 12 in each case.

The screen divider 35 also has a radial ring 32, the sealing inserts 12 partially coming to lie under the radial ring 32, so that they close the respective screen sector 33 together with the radial ring 32 in a media-tight manner.

Then, as shown, for example, with FIGS. 7 to 9, the shielding bridge 25 can be applied to the line element sheaths 8 of the line elements 2 that are still exposed. As shown in FIG. 5, a shielding bridge 25 is thus formed which encompasses the outer shielding shell 20, the inner shielding shells 24 and the housing part 30 electrically conductive and non-detachable, in particular cohesively, connects to one another.

As shown in FIG. 6, a flexible sheathing 50 is then applied to the connector 100, for example for the purpose of sealing and strain relief, but also for aesthetic reasons and also to obtain protection against accidental contact. In this way, the commercially available form of the connector 100 is finally obtained.

FIGS. 7 to 9 show the positioning of the shielding bridge 25 in a casting mold 300. FIG. 7 initially shows the empty casting mold 300 which has a filling opening for the material used to position the shielding bridge 25, for example a low-melting metal alloy. Furthermore, the casting mold 300 has a connector receiving opening 304 into which the connector 100 can be inserted. Typically, the casting mold 300 is constructed in the form of two F-halves, which can be paired with one another and closed, with FIGS. 7 to 9 each showing only one F-half of the casting mold for easier understanding of the construction.

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

FIG. 9 shows the casting mold 300 with the connector 100 inserted, the shielding bridge 25 being 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.

FIG. 10 shows a detailed view of a housing part 30 which has a sealing ring 28, the screen divider 35 with radial ring 32 and screen webs 34. The sealing ring 28 serves as a seal in the casting mold, in particular when the shielding bridge 25 is still liquid, that is to say in particular the liquid metal. On the connector 100 that is finished later, it can also be used together with the end coating, ie the flexible sheathing 50, as a sealing element against penetrating moisture. The ends of the contact sleeves 16 are inserted into the shield sectors 33, each contact sleeve 16 having two passage openings 161, 162 (see FIG. 13). Sealing inserts 12 are to be inserted into the remaining areas of the shield sectors 33, see FIG. 18. The housing part 30 finally has a screw thread 40 in order to connect the housing part 30 to a further connecting part. The screen divider 35 has an inner hollow part 38 in which a coding nose 36 is arranged. The coding tab 36 indicates the correct direction of connection of the line elements 2 to the respective shield sectors 33 of the housing part 30.

FIG. 11 shows a housing part 30 with a screen divider 35 and four screen webs 34. In this example, no contact sleeves 60 are provided or required. This shape of the housing part 30 can be provided, for example, if an internal thread or some other connection technology than the screw thread 40 is to be provided on the distal end of the housing part 30. For example, the embodiment of FIG. 11 shows a detail of FIG. 10.

FIG. 12 shows a further connector 100 in a partially assembled state, the cable end 10 being stripped of the cable insulation 4 and the conductor ends 2 being exposed. In any case, the outer shielding sleeve 20 can be contacted between the insulation 4 and the section 4a of the cable insulation, but also at the end piece of the cable insulation 4. The stripped conductor ends 2a (see, for example, FIG 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.

A contact sleeve 16, which is able to accommodate two contact elements 14 in pairs, can be pushed onto the contact elements 14 in a particularly advantageous manner. The contact sleeve 16 is pushed onto the contact elements 14 in such a way that the contact elements 14 are pushed into the passage openings 161, 162 and the contact sleeve 16 is brought up to the line element sheaths 8. For better insulation, the contact sleeve 16 also has an insulating collar 163 between the two passage openings 161, 162. Finally, the contact sleeve 16 also covers most of the contact elements 14 by means of the sleeve extension 164.

FIG. 14 shows the plug connector 30 equipped with the contact sleeves 16 described in accordance with FIG. 13 in the partially assembled state, two line elements 2 being pushed into a contact lens 16 in each case. Since the cable 10 of the example in FIG. 14 has eight line elements 2, four contact sleeves 16 are provided, into each of which two line elements 2 are inserted.

FIG. 15 shows an alternative embodiment to FIG. 14 in which the line elements 2 are twisted or twisted with one another in pairs in the exposed area are intertwined, so-called in a "twisted pair arrangement". The line elements 2, which are each twisted with one another in the area that has remained free, are inserted in pairs into a contact lens 16.

16 shows an alternative embodiment to FIGS. 14 and 15, which can optionally also be cumulatively equipped with it, with FIG. 16 having second line element sheaths 9 in the exposed area, the line elements 2 arranged in pairs being inserted into second line element sheaths 9 in pairs. The second line element sheaths 9 are, in particular, each a piece of shrink tubing or an electrically insulating material.

FIG. 17 now shows the embodiment of FIG. 14 with the housing part 30 attached, which is pushed onto the line elements 2 or the contact elements 14 from the front to such an extent that the contact sleeves 16 with their end or with the passage openings 161, 162 in the respective shield sector 33, for example below the radial ring 32 come to rest. If necessary, a small piece of stripped conductor end 2a can also protrude from the contact sleeves 16. In an advantageous manner, this is not essential, since these areas are also covered in the following.

FIG. 18 shows an embodiment of a sealing insert 12 prepared for insertion into a screen sector 33 of the screen 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 embodiment shown with FIG. 18, these are two passage openings 121, 122, so that a pair of line elements 2 can be passed 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 FIG. 19 can now be provided with the shielding bridge 25. The shielding bridge 25 is advantageously introduced 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 shielding divider 35 and up to the sealing ring 28. This can be carried out, for example, with a casting mold, as shown in FIG.

FIG. 20 shows the connector 100 with the shielding bridge 25 introduced for the production of the shielding cover, in particular a complete shielding cover from the outer shielding cover to the sealing ring 28, the inner shielding covers 24 also being through-connected and also inside between the Line elements 2 are plated through. Thus, the intermediate shielding remains between the line elements 2, in particular between the pairs of line elements 2 to the other line elements 2 over the entire length of the connector 100 as well as over the entire length of the line elements 2 from the connector 100 to the cable 10 in Tact. This is because the material of the shielding bridge 25 advantageously flows between the line elements 2 in that the shielding bridge 25 is poured directly onto the line element sheaths 8 and flows into there between the line elements 8, 2. In other words, with the applied shielding bridge 25, each line element 2 is surrounded radially on all sides by the material of the shielding bridge 25, that is to say in particular with respect to the remaining line elements 2 of the other line element pairs. Furthermore, the shielding bridge 25 is also through-contacted with the shield divider 35 and in particular with all shield webs 34 of the shield divider 35. It is particularly advantageous if there is an integral connection of the shielding bridge 25 to the shield webs 34 of the shield divider 35. It is also preferred if the same material contact can also be produced with the outer shielding cover 20 and the inner shielding covers 24, so that the shielding bridge 25 is a material connection bridge from the shield divider 35 via the shielding bridge 25 to the outer shielding cover 20 or the inner one Shielding covers 24 provides.

Finally, FIG. 21 shows the connector according to FIG. 20, with a protective jacket 50 being applied to the area of the shielding bridge 25, for example by extrusion coating, as is customary in the trade. If necessary, the protective sheath 50 can be clamped or crimped in order to secure the position on the cable 10 or to achieve strain relief and / or media-tightness.

FIG. 22 shows a plan view of a plug connector 100 in the fully assembled state, the section lines A and B being intended to represent the views of FIGS. 23, 24 and 25. FIG. 23 shows a longitudinal section through a connector as indicated by FIG. 22 along the line AA. The plug connector 100 shown in FIG. 23 is shown in the fully assembled state, with the protective jacket also already being applied. In the longitudinal section of FIG. 23, the profile of the shielding bridge 25 is clear, which extends around the line elements 2, between the line elements 2 and as far as behind the section 4a of the cable insulation 4. The shielding bridge 25 makes material contact with the housing part 30, 32 and thus provides the shielding bridge completely. On the inside, the shielding bridge 25 makes contact with the shielding divider 35.

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

The line elements 2 are pushed into contact elements 14 at their stripped conductor ends 2a and fastened therein. Contact sleeves 16 are arranged around the contact elements 14 to accommodate the contact elements 14. In the area of the screen divider 35, sealing inserts 12 are arranged to seal the contact sleeves 16 or the plug side from the shielding bridge 25 or the cable side of the screen divider in a media-tight manner. The cable 10, as shown in FIG. 23, can also have a plurality of line elements 2, which are not shown in the illustration of FIG. 23 due to the selected perspective.

FIG. 24 shows a further example of a plug connector 100 in the fully assembled state, with a plurality of eight line elements 2 in the housing part 30 being in contact with contact elements 14. As an example, two line elements 2 are shown in sectional profile, the line elements 2 each being enclosed by a line element casing 8. The shielding bridge 25 is made of cast metal material, in particular a low-melting metal alloy, cast in situ onto the line elements 2 or their line element sheaths 8, so that the shielding bridge 25 preferably extends in one piece radially around each of the line elements 2. Furthermore, the shielding bridge 25 contacts both the outer shielding sleeve 20 and the inner shielding sleeve 24 in order to contact both or all of the shielding sleeves 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 line elements 2 is maintained completely and without gaps.

FIG. 25 shows a radial section along the section line AA as shown in FIG. In the area of the screen divider 35, the line elements 2 are passed through four sealing inserts 12, a sealing insert 12 being arranged in each screen sector 33. the During assembly, the coding device 36 instructs the directionally correct arrangement of the line elements 2 on the housing part 30.

FIG. 26 shows an embodiment of the housing part 30 of the plug connector 100, the contact sleeves 16 coming to rest 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 FIG. 31). For example, the housing part 30 can be provided in this partially assembled form with preassembled 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.

FIG. 27 shows a side view of a connector 100 in the fully assembled state, the sections shown below along the section line A, B and D or the front view E with FIGS. 27a, 27b, 27c and 30 being shown.

FIG. 27a shows a radial section along the section line AA, as indicated in FIG. 27, i.e. in the area through the shielding bridge 25, which individually surrounds all line elements 2 radially on all sides, so also each pair of line elements with one another, 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 enclosed in an electrically separating manner by line element sheaths 8. The line elements 2 therefore do not carry an electrical shielding insert 25.

FIG. 27b shows an embodiment alternative to FIG. 27a, which likewise shows a radial section along the section line BB, as shown in FIG. 27, in the area of the shielding bridge 25 of the plug connector 100. 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 initially enclosed radially on all sides by the line element shell 8, above it by the second line element shell 9 radially on all sides and in turn enclosed above it by the shielding bridge 25, preferably radially on all sides. Depending on the embodiment, the area between a pair of line elements 2, that is to say the area within the second line element casing 9, is not filled by the shielding bridge 25. Nevertheless, it is clear that in this case too, each line element 2 is preferably surrounded radially on all sides by the shielding bridge 25 on the outside. For example, the line element 2 numbered at the top left in FIG. 27b is adjacent from its partner, which in FIG the same second line element sheath 9 is arranged. This partner lies in an imaginary alignment from the line element 2 to the next pair of line elements 2. Nevertheless, there is material from the shielding bridge 25 between this line element 2 and the next pair of line elements 2, which is enclosed by a further second line element shell 9 The material of the shielding bridge 25 is thus arranged around each line element 2 in all radial directions. It is of particular importance that between each pair of line elements 2, which is enclosed by a common second line element sheath 9, to the other pairs of line elements 2, which are surrounded by other second line element shells 9, the material of the shielding bridge 25 is in each case arranged and thus creates a shielding effect between the pairs of line elements 2. The pairs of line elements 2 are thus also shielded from one another.

FIG. 27c shows a radial section along the section line D-D, as indicated in FIG. 27, that is in the region of the cable 10. Each pair of line elements 2 is shielded from the other pairs of line elements 2 by an inner shielding sleeve 24. Furthermore, the outer shielding sleeve 20 also surrounds all line elements 2 together. The conductor pairs, which are each inserted into an inner shielding sleeve 24, are inserted into cable filling material, such as cable rubber, and thus fixed. The inner shielding sleeve 24 can be, for example, a thin aluminum foil or a plastic foil onto which aluminum or another metal material is vapor-deposited. Metal material is preferred for insulation. If the inner shielding sleeve 24 and / or the outer shielding sleeve 20 is made of a metal material or comprises a metal material, a material bond with the shielding bridge 25 can be produced.

FIG. 28 shows a further alternative embodiment of a partially assembled plug connector 100, the line elements 2 being arranged rotated in the area that is still exposed and being inserted into the contact sleeves 16.

FIG. 29 shows yet another alternative embodiment of the partially assembled plug connector 100, the respective pairs of line elements 2 each being provided with a second line element sheath 9 such as a shrink tube.

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

FIG. 31 shows a longitudinal section along the section line C1 -C1 of FIG. 30 through a ready-made plug connector 100. 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, i.e. also between the line elements 2. The shielding bridge 25 extends from a free area between the section 4a of the cable insulation and the cable insulation 4 on the cable side up to the Contact ring 28 of the housing part on the housing side and makes contact with the screen divider 35 as well as the inner shielding sleeves 24 and the outer shielding sleeve 20.

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

FIG. 33 shows a plan view of the plug face 18b of the mounting part 44. The plug face 18b is arranged on a printed circuit board or mounting plate 42.

Finally, FIG. 34 shows a longitudinal section through the connector 100 according to FIG. 32 with the mounting part 44 mounted thereon.

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 the individual pairs of line elements 2 among each other. Here, a shielding bridge is placed on the exposed area between the cable 10 and the housing part 30 so 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 radially on all sides from the The material of the shielding bridge 25, that is to say, in particular, is enclosed radially on all sides by the shielding bridge 25. Thus, a gapless and complete shielding towards the outside can be achieved at the same time with regard to the outer shielding and thus the outer shielding sheath 20 and also between the line elements 2 among one another, i.e. towards the inner shielding sheath 24 of the respective pair of line elements as well as to the shield divider 35 and the housing part 30, 32 out. A one-piece shielding bridge is used, which also provides 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-releasable connection that the shielding bridge 25 provides is in particular a material connection, for example by a soldering process. The screening bridge 25 presented is preferably cast directly and immediately from a metal material in situ on the line element sheaths 8 or second line element sheaths 9 in the ring area shown.

It is evident to the person skilled in the art that the embodiments described above are to be understood as examples and that the invention is not restricted to them, but rather can be varied in many ways without departing from the scope of protection of the claims. It can also be seen that the features, regardless of whether they are in the
