Abstract

In order to simplify the assembly and wiring of the optoelectrical plug connector (3, 3') and the sub-distributor (6) and sub-distributor system equipped therewith, it is proposed to use special module housings (100). These module housings can accommodate a plurality, in particular eight, identical and / or different optoelectrical transducers (2, 2') and are installed in the plug connector (3, 3') between the electrical plug contacts (311) and the multi-core optical cable (58), i.e. the core wires (5l). Thereby, the susceptibility to faults is significantly increased and the assembly is significantly simplified due to the improved clarity.

Description

TECHNICAL FIELD

[0001] The invention is based on an optoelectronic module according to the preamble of independent claim 1.

[0002] Furthermore, the invention is based on an optoelectronic plug connector having at least two optoelectronic modules according to claim 1.

[0003] Furthermore, the invention is based on an optoelectronic distributor having a central optoelectronic plug connector of the type described above and a plurality of decentralized plug connectors, each having at least one optoelectronic module.

[0004] Such modules, plug connectors and sub-distributors are required in order to install and operate complex signal distributors without errors or disturbances. BACKGROUND

[0005] Optoelectrical transducers, so-called "transceivers" (Tx) and "receivers" (Rx), as well as plug connectors in combination with such optoelectrical transducers are known from the prior art.

[0006] EP 1 180 704 A2 relates to a plug and system for electrical connections of an assembly support in the field of switching technology. Here, at least one optical transmission cable can be connected to the plug. An optoelectrical transducer is accommodated in the housing of the plug itself. Furthermore, the optoelectrical transducer is in contact with a printed circuit board with plug contacts, which can be plugged or soldered to the printed circuit board. On the plug side there are also plug contacts for connecting optical signal cables. At least one of the plug contacts is used to supply power to active components in the plug. In particular, the optoelectrical transducer is supplied via the plug contacts.

[0007] The document DE 202017100608 U1 criticizes the above-mentioned construction form on the one hand on the basis of the contact taking place outside the plug connector housing and on the other hand on the basis of the small number of optical fibers connectable to the unit and furthermore the undesired high space requirement. On the basis thereof, the document proposes a plug connector having a printed circuit board and at least one optoelectrical transducer. The transducer is accommodated in a transducer housing and arranged on the printed circuit board and in electrically conductive connection therewith. Optical fibers are accommodatable in the transducer housing.

[0008] The disadvantage of this prior art is that the optoelectrical plug connector, in particular the optoelectronic distributor having such a plug connector, generally requires undesired manufacturing and / or installation effort. The assembly, distribution and wiring of the electrical-optical modules on the printed circuit board inside the plug connector is complex. It has proven to be a great demand on the part of the customers to be able to optionally use optoelectrical transducers from different manufacturers, wherein the geometry of their transducer housings naturally differs. Furthermore, there is a high demand for flexible adaptation of the optoelectrical wiring, in particular for central sub-distributors, especially in the field of rail technology.

[0009] The German Patent and Trademark Office investigated the following prior art in the priority application of the present application: DE 202017100608 U1, EP 1180704 A2 and US 2002 / 0141706 A1. SUMMARY

[0010] It is therefore the object of the present application to indicate an optoelectronic module, an optoelectronic plug connector and an optoelectronic distributor, which can be manufactured, assembled, configured and / or installed with as little effort as possible and at the same time can be adapted as flexibly as possible to the requirements of individual customers.

[0011] The object is solved by the subject matter of the independent claims.

[0012] The optoelectronic module has a module housing and a plurality, in particular eight, optoelectronic transducers. These transducers have the following parts:

[0013] - a transducer housing with internal transducer electronics arranged therein;

[0014] - and a plurality of electrical terminals electrically connected to the transducer electronics, which protrude from the transducer housing; and - an optical terminal arranged in the transducer housing, which can receive and / or emit light through a window in the housing wall of the transducer housing.

[0015] The module housing serves on the one hand to accommodate the optoelectronic transducers and to fasten them together on a printed circuit board. On the other hand, the module housing serves to connect the optical core wires, i.e. the individual core wires of a multi-core optical cable, in particular optical fibers (LWL), to the optical terminals of the transducers and to relieve stress. In particular, the multi-core optical cable can have eight optical core wires, i.e. optical individual core wires.

[0016] The module housing is designed in at least two parts and has a housing lower part and a housing upper part, which can be connected and fixed to the housing lower part, in particular can be snap-locked thereon.

[0017] In the housing lower part, a transducer chamber is arranged for each optoelectronic transducer to be accommodated in the module housing in order to accommodate the respective optoelectronic transducer therein in a form-locked manner.

[0018] In particular, a transducer recess can be arranged in the housing upper part for each optoelectronic transducer. By combining the housing upper part with the housing lower part, the transducer recesses initially lie above the transducer chambers. This allows the transducers to be held in their respective transducer chambers in a form-locked manner in each direction. In particular, the module housing can have eight transducer chambers and transducer recesses.

[0019] The converter chamber of the housing lower part is designed open at the end provided for fastening on a printed circuit board or has one or more contact through-openings at this end in order to pass through electrical connections of the optoelectronic converter and to make electrical contact with the printed circuit board.

[0020] The housing lower part and the housing upper part each have a contact face. The two contact faces abut against each other, in particular overlap each other, when joined, and are therefore referred to as common contact faces. On these common contact faces, each converter chamber housing upper part and housing lower part has a part of the cable channel leading to the converter chamber, i.e. an upper part and a lower part of the cable channel, respectively, so that a complete cable channel is formed after assembly of the housing upper part and the housing lower part, respectively. The cable channel is thus provided for feeding the optical fiber to the converter chamber and thus to the optoelectronic converter arranged therein, respectively.

[0021] Advantageous configurations of the application are specified in the dependent claims and the following description.

[0022] In a preferred embodiment, the housing upper part has a cable fixation recess for each cable channel, which is connected to the respective cable channel, more precisely to the upper part of the respective cable channel, and into which a fixation element can be inserted, respectively, in order to stress-relieved fixation of the respective optical fiber on the module housing.

[0023] The housing lower part and the housing upper part of the module housing are preferably fastened to each other by snap-in, screwing, gluing, crimping, casting, heat pressing, riveting, splashing and / or form-locking insertion. Here, the advantages of snap-in, screwing and insertion are that they are reversible, i.e. the connection can be separated non-destructively in order to replace the converter, for example. Snap-in is less labor-intensive and allows the upper part and the lower part to be joined in the axial direction of the optoelectronic converter, which makes it particularly easy for them to be fixed in their converter chambers and thus particularly advantageous.

[0024] In a preferred embodiment, the housing lower part and the housing upper part each have a step. The housing lower part has an inner step and the housing upper part has an outer step. This facilitates increasing the packing density and simplifying the insertion of the optical fiber.

[0025] The first group of cable channels can then be arranged in a first layer and the second part of the cable channels can be arranged in a second layer. The first layer can here be offset from the second layer by at least the thickness of the cable channels.

[0026] The advantage of this is that one group of optical fibers can be inserted into the module housing in a first layer and a second group of optical fibers can be inserted into the module housing in a second layer, thereby increasing the packing density. This also makes it easy to manually insert the fibers into the respective cable channels.

[0027] As already mentioned, the optoelectronic transducers each have a transducer housing, in which the internal transducer electronics are arranged, and the already mentioned electrical connections, which can be designed for example as connection pins, protruding from the housing. In addition, they have the mentioned optical connection arranged in the transducer housing, which can receive and / or emit light through a window in the housing wall. The optical core of the optical cable is now fed to this optical connection by means of the cable channel of the module housing. On the other hand, as already mentioned, the electrical connections of the transducers can be electrically conductively connected, in particular soldered, to the printed conductors of the printed circuit board.

[0028] Depending on their internal transducer electronics, a part of the optoelectronic transducers can be transceivers (Tx), i.e. they receive electrical signals and convert them, for example by means of LEDs ("light emitting diodes"), into optical signals.

[0029] Another part of the optoelectronic transducers can be receivers (Rx) depending on their internal transducer electronics, i.e. they receive optical signals and convert them into electrical signals.

[0030] In a preferred embodiment, all optoelectronic transducers have the same housing size.

[0031] In another embodiment, at least two optoelectronic transducers have different housing sizes, i.e. their transducer housings differ from each other in shape, for example because they come from different manufacturers.

[0032] In a preferred embodiment, the module housing is able to accommodate in a form-fitting manner in its transducer chamber optoelectronic transducers with the above-mentioned different housing sizes. As already mentioned, these different optoelectronic transducers can come from different manufacturers and can be selectively used by the customer depending on price and / or quality and / or other specific properties, etc. decision criteria, which offers the user a so-called "Second Source", thus making procurement more flexible and ensuring supply.

[0033] Despite the different housing sizes, both types of transducers can be accommodated in the module housing in the same transducer chamber in a form-fitting manner, since the transducer chamber has a suitable contour that is specifically adapted to both housing sizes in order to achieve the above-mentioned accommodation. This can be done depending on the type of transducer housing involved, for example by means of a funnel shape and / or a corresponding bridge or other special geometric adaptation of the transducer chamber shape, which the person skilled in the art details based on the various transducer housing designs.

[0034] The optoelectrical plug connector has a plug connector housing. In the plug connector housing, an internal printed circuit board is arranged, on which at least two optoelectrical modules of the aforementioned type are arranged. The printed circuit board has printed conductors, which are in electrically conductive connection on the connection side with at least one electrical contact of the optoelectrical transducer and on the plug side with an electrical plug contact of the plug area of the plug connector.

[0035] In particular, the plug connector housing can have a separate cable outlet for each optoelectrical module.

[0036] The optoelectronic distributor has a central optoelectrical plug connector of the aforementioned type and a plurality of decentralized optoelectrical plug connectors, wherein the decentralized plug connectors each have at least one, in particular exactly one, optoelectrical module.

[0037] This also discloses a sub-distributor in which the decentralized plug connectors have exactly one optical module. This is particularly advantageous due to the clarity and simplicity and inexpensive manufacturability.

[0038] This also still discloses a sub-distributor in which the decentralized plug connectors can have a plurality of optical modules, although the aforementioned variant of the decentralized plug connectors in which there is only one optoelectrical module is particularly popular due to its simple and easy-to-manage structure. However, in individual cases, more complex sub-distributors can be required, even possibly a tree structure. The variant can be particularly advantageous for this, as these distributors can be cascaded, i.e. the central plug connector of another sub-distributor of the aforementioned type can advantageously plug in again such decentralized plug connectors in order to achieve a sub-distributor system overall with a complex corresponding sub-branch tree structure.

[0039] In a preferred embodiment of the sub-distributor, the number of optoelectrical modules in the central optoelectrical plug connector matches the number of all optoelectrical modules of all decentralized optoelectrical plug connectors belonging to the sub-distributor. In short, the module count of the central plug connector is as many as the sum of the decentralized plug connectors of the sub-distributor.

[0040] In other aspects, the decentralized plug connectors can be configured similarly to the central optoelectrical plug connector.

[0041] Furthermore, the optoelectronic distributor has a plurality of optical cables, each of which has a plurality of, in particular eight, optical core lines, wherein the optical core lines of the optical cables are connected on the one hand to one of the optoelectrical modules of the central optoelectrical plug connector and on the other hand to the optoelectrical modules of one of the decentralized plug connectors or possibly to one of the optoelectrical modules of one of the decentralized plug connectors.

[0042] In particular, each optoelectrical module of the at least one central optoelectrical plug connector can be connected via a respective optical cable to exactly one optoelectrical module of one of the associated decentralized optoelectrical plug connectors.

[0043] In short, this means that in an advantageous embodiment, the optical module of a central connector can always be connected to exactly one optical module of a decentralized connector via exactly one fiber optic cable. For example, the central connector can have three modules, each of which is connected via a fiber optic cable to a corresponding decentralized connector, which has only one module. This sub-distributor thus has one central connector and three decentralized connectors. This makes the disassembly / sub-distribution easy to understand, easy to construct, easy to assemble, and ergonomic. As can be seen, this structure is very clear and very insensitive to errors during construction.

[0044] As mentioned above, an optoelectronic distributor system is also disclosed herein. The sub-distributor system has a plurality of sub-distributors of the above type.

[0045] In a first embodiment, these may be interconnected in the above-mentioned tree structure.

[0046] Alternatively or additionally, multiple sub-distributors can also be operated in parallel within a sub-distributor system. In an advantageous embodiment, the multiple sub-distributors can be connected to one another, for example using cable ties, to form a common cable harness. The sub-distributor system then comprises multiple central optoelectronic connectors that operate in parallel. Furthermore, for each of these central connectors, there are multiple decentralized connectors, each of which is connected to the central connector via a fiber optic cable or at least optical cores.

[0047] In another advantageous embodiment, the optoelectronic module can also be arranged on a conventional printed circuit board, such as a printed circuit board of an electronic device, so as to conveniently connect the optical core to the printed circuit board electronics. This also provides an especially advantageous optical interface to be assembled in the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 2a 、 2b shows the assembled photovoltaic module from two different perspectives;

[0051] Figures 3a-3d A plug connector with a housing and two optoelectronic modules is shown;

[0052] Figure 3e 、3f A plug connector is shown without a housing.

[0053] Figure 4a 4b Two different optical distributors are shown.

[0054] The drawings contain partly simplified schematic drawings. In some cases, the same reference signs are used for identical, but possibly not identical, elements. Different views of identical elements can be scaled differently. DETAILED DESCRIPTION

[0055] Figure 1a 1b Two exploded views of an optoelectronic module are shown, respectively from two different perspectives.

[0056] The optoelectronic module 1 has a plurality of optoelectronic transducers 2, 2' which are designated in detail in Figure 1a and which can differ in their structural form.

[0057] The optoelectronic transducers 2, 2' each have a transducer housing 20, 20' with internal transducer electronics arranged therein, and electrical connections 21, 21' which are in electrically conductive connection with the transducer electronics and which project from the transducer housing 20, 20'. Furthermore, the optoelectronic transducers 2, 2 each have a light connection 22, 22' arranged in the transducer housing 20, 20', which is able to receive and / or emit light through a window in the housing wall of the transducer housing.

[0058] The optoelectronic module 1 has a module housing 100 which is designed in two parts and consists of a housing upper part 11 and a housing lower part 12.

[0059] A transducer chamber 120 is arranged in the housing lower part 12 into which the optoelectronic transducers 2, 2' can be inserted in a form-locked manner. It is irrelevant here that the transducer housings 20, 20' of the different transducers 2, 2' can have different housing shapes, since the transducer chamber 120 of the housing lower part 12 is adapted to a plurality of transducer housings 20, 20' and thus to various transducer housings 20, 20' for form-locked reception.

[0060] At a lower end which is provided for contact with the printed circuit board 4, the transducer chamber 120 each has a contact through-opening 125 which is shown and designated in Figure 1b for the electrical connections 21, 21' of the transducers 2, 2' to pass through and contact the printed circuit board 4.

[0061] ​​The upper housing part 11 can be latched on the lower housing part 12 by means of latching hooks 117 on the latching edges 127 of the lower housing part 12. Furthermore, the upper housing part 11 has guide pins 116 and the lower housing part has guide recesses 126, whereby the joining of the two housing parts 11, 12 is facilitated. The upper housing part 11 and the lower housing part 12 each have a common contact surface 114, 124, by means of which the upper housing part and the lower housing part are connected to one another in the joined state.

[0062] A part of the cable channel is formed in each of the common contact surfaces, i.e. an upper part 118 of the cable channel 18 is formed in the upper housing part 11 and a lower part 128 of the cable channel 18 is formed in the lower housing part 12.

[0063] The upper housing part 11 also has a cable fixing recess 119 for each cable channel 18, which connects the upper side 15 to the upper part of the cable channel 118. For this purpose, the optoelectronic module 1 has a cable fixing element 10 for each cable channel 18, which is inserted in a form- and force-locking manner into the cable fixing recess 119 in order to stress-relievedly fix the inserted optical fiber 58 in the cable channel 18.

[0064] Furthermore, the upper housing part 11 has an outer step 113 and the lower housing part has an inner step 123.

[0065] The significance of these steps 113, 123 can be seen from Figure 2a and 2b The two housing parts 11, 12 here together form a module housing 100. A total of eight optoelectronic transducers 2, 2' are arranged in the module housing 100.

[0066] The transducers 2, 2' and the cable channels 18, 18' are here distributed on two different layers, which are staggered to one another by at least one cable channel diameter by means of the stepped structure. It is easy to see that this achieves a higher packing density. It is also advantageous for the manual insertion of the optical fibers 51 during assembly and the fixing of the optical fibers by means of the cable fixing elements 10.

[0067] In particular, it is easy to see in Figure 2b that the electrical connections 21, 21' of the optoelectronic transducers 2, 2' pass through the contact through-openings 125 of the lower housing part 12 and protrude for connection to the printed circuit board 4.

[0068] First of all, it can be seen in Figure 3aIn the middle one sees a limited view of the printed circuit board 4 and its assembly surface (not explicitly designated for the sake of clarity), which as a component of the optoelectronic plug connector 3 is arranged in its housing 30. On the assembly surface of the printed circuit board 4 two optoelectronic modules 1 are arranged and electrically connected to the electrical contacts 21, 21' of their optoelectronic transducers 2, 2'.

[0069] The plug connector 3 has a plug-in area 31 with plug-in contacts 311, which are also electrically connected to the printed circuit board 4, i.e. are plugged onto it. However, for the sake of clarity this connection / contact is not shown in the figures.

[0070] Furthermore, the plug connector 3 has a cable connection area 32. Two cable outlets 320 are arranged in this cable connection area. One optical cable 58 each passes through each cable outlet 320. Each optical cable has eight optical core wires 51, wherein each four optical core wires 51 are combined into a bundle. One of them is designated Tx. Its optical core wires are used for connecting those optoelectronic transducers 2, 2' which are designed as transmitters (Tx), respectively. These transmitters (Tx) convert electrical signals of the plug-in contacts 311 into optical signals, which are transmitted via their optical contacts 22, 22' to the optical core wires 52 connected thereto. The other bundle is designated Rx and is used for connecting to those optoelectronic transducers 2, 2' which are designed as receivers (Rx), respectively. The receivers (Rx) convert optical signals of the respectively connected optical core wires 51 into electrical signals, which are transmitted via their electrical contacts 21, 21' to the respective plug-in contacts 311 via the printed circuit board 4. Thus each optical cable 58 has four outgoing and four return lines. Furthermore, the housing 30 has a display window 330, which is still open in this figure.

[0071] Figure 3b The plug connector 3 with the housing 30 is shown, which is closed by an unmarked housing cover. The arrangement shown here differs from that shown in the preceding figures in that the cable outlets 32 are closed by cable sealing sleeves 321, wherein each cable sealing sleeve 321 eliminates the stress of the passing bundle of core wires. In addition, the display window 330 is closed by a blind 33.

[0072] This arrangement in the open state in Figure 3c and in the closed state in Figure 3d modifies the plug connector 3 in that instead of the aforementioned blind 33 in the display window 330 a status display 34 with a respective LED ("light emitting diode") is arranged for each optical core wire 51 / each optoelectronic transducer 2, 2'. Now as soon as a signal is transmitted via the respective optical core wire 51 or the optoelectronic transducer 2, 2' connected thereto, the respective LED lights up indicating this signal flow. For this purpose, the status display 34 is connected to the printed circuit board 4, from which the status display 34 receives the respective electrical signal.

[0073] Figure 3e and 3f from two different views shows a similar arrangement, but without the plug connector housing 30. Figure 3a

[0074] In this illustration, the printed circuit board 4 can be seen particularly clearly. In particular, Figure 3f The underside of the printed circuit board 4, which is opposite the aforementioned assembly surface, is also visible (not further labeled for reasons of clarity) and allows the fixing elements 10 to be seen, which are arranged in the printed circuit board 4. Through these separating openings 40, the fixing elements 10, which are covered thereon, can be removed from the cable fixing recesses 119 of the module housing 100 using a tool, for example a pointed object such as an electric screwdriver or the like.

[0075] Figure 4a A first embodiment of the optoelectronic distributor 6 is shown in a schematic illustration.

[0076] This first sub-distributor 6 has a very simple form which can be imagined and consists of a central plug connector 3 of the type described above and two decentralized plug connectors 3', which differ from the central plug connector 3 in that they each have only one optoelectronic module 1. The central plug connector 3 thus has as many optoelectronic modules 1 as the decentralized plug connectors. The modules 1 of the decentralized plug connectors are each arranged on a printed circuit board 4', which in this embodiment has only eight printed conductors (of course any other number is also possible). The decentralized plug connectors thus also each have only eight plug contacts 311' in this example. On the cable connection side, the central plug connector 3 is connected to the optoelectronic module 1 of one of the decentralized plug connectors 3' at one of its optoelectronic modules 1 by means of a corresponding optical cable 58 with eight core lines.

[0077] The advantage of this design is that it is constructed in a particularly clear and error-free manner and thus allows very simple assembly.

[0078] Figure 4b A second sub-distributor 6" with one central plug connector 3 and three decentralized plug connectors 3" is shown.

[0079] As can be seen from this illustration, the number of optoelectronic modules 1 of the decentralized plug connectors 3' does not necessarily have to match the number of optoelectronic modules 1 of the central plug connector 3. Rather, the optoelectronic transducers 2, 2' of these modules 1 can also be freely connected to one another by individual optical core lines 51, if desired.

[0080] The advantage of this design compared to the prior art is that the distribution of the plug contacts 311, 311' allows maximum flexibility while providing simplification of the assembly.

[0081] ​The optoelectronic module 1 of the central plug-in connector 3 and the decentralized plug-in connector 3' can be of identical construction in both embodiments.

[0082] Even if different aspects or features of the application are shown in the drawings in a combination, it will be apparent to those skilled in the art that such shown and discussed combinations are not the only possible combinations unless otherwise specified. In particular, mutually corresponding feature units or complexes of different exemplary embodiments can be interchanged.
