When assembled, the first connector device and the second connector device are intended to enter into a common plug connection, wherein the first connector device and the second connector device could be connected together, for example. The first connector device and the second connector device could conceivably jointly be part of a connector and, in the assembled state, be intended to jointly enter into a plug connection with a further connector. It would additionally be conceivable for the first connector device and the second connector device to be part of separate connectors and, in the assembled state, to be intended to enter into a plug connection with one another, in which the first connector device and the second connector device are plugged together, in particular plugged into one another.
The universal modules each include an optical contact, which is configured in particular as a ferrule. The optical contact could conceivably alternatively or additionally be configured as a lens and/or as a lens contact. The universal modules could for example comprise at least one component which holds the optical contact when assembled.
“Intended” should be understood to mean specially designed and/or equipped. Where an item is intended for a specific function, this should be understood to mean that the item fulfills and/or performs this specific function in at least one application state and/or operating state.
It is further proposed that the first connector device and the second connector device have, at least in places, mutually identical external geometries when assembled. In particular, when assembled the first connector device and the second connector device include, in each case viewed in the plug-in direction, at least one sub-region with mutually identical external geometries, wherein mutually identical external geometries may differ, for example with regard to manufacturing tolerances or the like. The first connector device and the second connector device in particular have, at least in places, an identical form factor when assembled. Such an embodiment may in particular result in particularly advantageous properties with regard to construction. In particular, it may provide particularly good compatibility. Furthermore, the number of parts can advantageously be kept low, especially with regard to connector receptacles, whereby cost efficiency may moreover in particular be increased.
It is additionally proposed that the first configuration module and the second configuration module have, at least in places, mutually identical external geometries when assembled. In particular, when assembled the first configuration module and the second configuration module include, in each case viewed in the plug-in direction, at least one sub-region with mutually identical external geometries, wherein mutually identical external geometries may differ, for example with regard to manufacturing tolerances or the like. The first configuration module and the second configuration module in particular have, at least in places, an identical form factor when assembled. Such an embodiment may in particular result in particularly advantageous properties with regard to construction. In particular, it may provide particularly good compatibility. Furthermore, the number of parts can advantageously be kept low, especially with regard to connector receptacles, whereby cost efficiency may moreover in particular be increased.
It is further proposed that the connector system include a receiving element including a first receptacle for the first connector device and a second receptacle for the second connector device. In particular, when assembled the first connector device and the second connector device are respectively received in the first receptacle and in the second receptacle of the receiving element. In particular, when assembled the receptacle at least partly and preferably completely encloses the first connector device and the second connector device in the circumferential direction. The receiving element is configured in particular as an overhousing surrounding the connector devices. The receiving element could in particular, without being limited thereto, be formed as an outer housing that is at least substantially protected from environmental influences. The receiving element could be at least partly and preferably completely sealed against environmental influences. In particular, the receiving element could be protected, in particular sealed, against the ingress of water, for example splash water and/or rainwater or the like, and/or advantageously protected against the ingress of dust. The receiving element could conceivably comprise sealing elements for sealing against environmental influences. When assembled, the receiving element could for example be protected, in particular sealed, with an IP67 rating, advantageously with an IP68 rating. In particular, the connector system, in particular at least the first connector device and/or at least the second connector device, is suitable for in particular permanent outdoor use. In this context, “at least substantially” should be understood to mean that any deviation from a specified value is in particular less than 25%, preferably less than 10% and particularly preferably less than 5% of said specified value. In particular, such an embodiment can improve construction. Such an embodiment can further provide, in particular, broad application possibilities for the connector system.
It is furthermore proposed that the first receptacle and the second receptacle be of mutually identical configuration. In particular, the first receptacle and the second receptacle are of at least substantially mutually identical configuration. It would also be conceivable for the first receptacle and the second receptacle to be configured in one piece, specifically in particular in the case where the first connector device and the second connector device are plugged together, in particular plugged into one another, in order to enter into the common plug connection. “One-piece” should be understood as at least materially bonded, for example by a welding process, an adhesive bonding process, an injection molding-on process and/or any other process that appears reasonable to a skilled person, and/or advantageously formed in one piece, such as for example by production from a casting and/or by production using a single- or multi-component injection molding method and advantageously from a single blank. Such an embodiment can in particular increase compatibility and/or advantageously reduce component diversity.
It is additionally proposed that the configuration modules each include at least one fixing element for fixing the respective connector device to the receiving element, in particular in the first and/or second receptacle. The fixing element is intended in particular for connecting the respective connector device to the receiving element. When assembled, the fixing element at least connects the respective connector device to the receiving element. At least one first element being “connected” to at least one further element should be understood to mean that the first element is advantageously connected to the further element via at least one frictional connection and/or at least one form-fit connection, for example via a riveted and/or latching connection and/or a tongue-and-groove connection and/or a clamping connection and/or a further connection which appears reasonable to a skilled person. The fixing element could conceivably be configured as a clamping ring for fixing the respective connector device to the receiving element. The fixing element preferably includes at least one latching means, advantageously a plurality of latching means and preferably exactly three latching means, for fixing the respective connector device to the receiving element. In this context, a “latching means” should be understood to mean a resilient means for producing a latching connection, which is intended to be elastically deflected during assembly. Such an embodiment makes it possible in particular to achieve a particularly advantageous construction, specifically in particular with regard to fixing the connector device in an overhousing.
It is further proposed that the configuration modules each include at least one configuration element and the universal module at least one housing element formed separately from the configuration element, wherein the configuration element and the housing element, when assembled, are arranged one behind the other, in particular adjoining one another, when viewed in the plug-in direction. This in particular allows advantageous properties to be achieved with regard to assembly. The plug-in direction is in particular an axial direction of the connector devices. The axial direction corresponds in particular to a main extension direction of the respective connector device, wherein the latter runs parallel to a longest edge of the smallest geometric cuboid which still fully encloses the connector device.
It is further proposed that the configuration element have a first receiving region for the housing element. When assembled, the housing element is in particular at least partly received in the first receiving region. In particular, when assembled at least one sub-region of the housing element is at least partly received in the first receiving region. The first receiving region could in particular be configured as a recess and/or a depression or the like. The first receiving region is preferably formed as a sub-region, arranged in the circumferential direction of the configuration element, which has a smaller diameter than regions of the configuration element adjoining the sub-region. Such an embodiment may in particular result in advantageous properties with regard to assembly.
It is further proposed that the housing element have at least one second receiving region, in particular two second receiving regions, for the configuration element. When assembled, the configuration element is in particular at least partly received in the second receiving region. In particular, when assembled at least one sub-region of the configuration element is at least partly received in the second receiving region. The second receiving region could in particular be configured as a recess and/or a depression or the like. Such an embodiment may in particular result in advantageous properties with regard to assembly.
It is further proposed that the configuration element and the housing element be arranged overlapping in at least one sub-region, in particular in the receiving region, when assembled. The configuration element and the housing element are preferably arranged to overlap, at least in the region of the first receiving region, when assembled. This allows advantageously stable fixing of the configuration element with the housing element.
It is further proposed that the configuration element of the first configuration module at least partly surround the first universal module and the configuration element of the second configuration module at least partly surround the second universal module when assembled. In particular, the configuration element of the first configuration module, in particular together with the housing element, forms an inner housing, in particular for the first universal module. In particular, the configuration element of the second configuration module, in particular together with the housing element, forms an inner housing, in particular for the second universal module. This may in particular further improve properties with regard to construction. It is in particular conceivable that a pre-assembled module be provided in this manner.
It is additionally proposed that the configuration modules be embodied to be interchangeable in order to change connector gender. The configuration modules are preferably embodied to be interchangeable even when already assembled in order to change connector gender. This in particular allows connector gender to be changed subsequently in the assembled state. This may in particular further increase compatibility and/or flexibility.
It is further proposed that the first configuration module and the second configuration module have different longitudinal extents. The longitudinal extent of the first configuration module and the longitudinal extent of the second configuration module, specifically with regard to a length in the axial direction of the connector devices, could for example conceivably differ from one another by at least 5%, advantageously by at least 10% and preferably by at least 15%. In particular, that configuration module which, when assembled, defines a female connector gender has a longitudinal extent that is longer by at least 5%, advantageously by at least 10% and preferably by at least 15%, than that configuration module which, when assembled, defines a male connector gender.
It is further proposed that the first configuration module comprise at least one coupling element for receiving at least one of the optical contacts and, in particular, the optical contacts, which is assemblable at least perpendicular to the plug-in direction via an assembly opening in the configuration module. In particular, the configuration element of the first configuration module includes the assembly opening. The coupling element preferably encloses the optical contact of the second connector device in a common plug connection with the second connector device. The coupling element could, in particular, be configured as a coupling sleeve which, for example, could be open when viewed in the axial direction. The coupling element is arranged in particular inside the configuration module in the assembled state. In particular, the coupling element is part of that configuration module which is intended to define a female connector gender of the connector device. This can further increase the compatibility and/or flexibility of the connector system.
It is additionally proposed that the first configuration module comprise at least one cover element which, when assembled, closes the assembly opening. The cover element could when assembled conceivably be latched together with the configuration element of the first configuration module. In particular, the cover element is press-fittable into the assembly opening for fixing with the configuration element of the first configuration module. The cover element could moreover conceivably rest against the coupling element inside the configuration module, in particular inside the configuration element. This may improve construction, in particular in terms of durability and/or stability.
It is further proposed that the cover element be assemblable at least perpendicular to the plug-in direction. This may in particular greatly simplify assembly. Fixing of the cover element to the configuration element may in particular be simplified.
It is further proposed that the cover element outwardly bound the first configuration module in at least one sub-region. In particular, the cover element outwardly bounds the first configuration module at least in a sub-region in flush manner with regard to an outer face of the first configuration module. In particular, the cover element outwardly bounds the configuration element at least in a sub-region in flush manner with regard to an outer face of the configuration element. In this way, particularly advantageous properties may in particular be achieved with regard to stability. In addition, an advantageously compact form factor of the first configuration module, in particular of the first connector device, may in particular be provided.
It is moreover proposed that the first configuration module comprise a clamping ring for fixing the cover element, in particular to the configuration element. This may further improve stability.
The fixing element of the first configuration module and the clamping ring could for example be configured separately from one another. If the fixing element of the first configuration module and the clamping ring are configured in one piece with one another, construction may be further improved, in particular in terms of a compact form factor.
It is further proposed that the connector devices each comprise a plurality of independent strain relief units. The connector devices preferably each include at least three independent strain relief units for an optical cable. The connector devices, specifically in particular the universal modules, could for example each include a C spring which is intended in the assembled, in particular prefabricated, state with a cable, in particular to clamp an optical fiber of the cable. Alternatively or in addition, the connector devices, specifically in particular the universal modules, could include at least one clamping block which, in the assembled, in particular prefabricated, state with a cable, is intended to clamp at least one coated fiber of the cable. Alternatively or in addition, the connector devices, specifically in particular the universal modules, could include at least one crimping sleeve which, in the assembled, in particular prefabricated, state with a cable, is intended to clamp at least one sheath of the cable. Such an embodiment may in particular result in improved properties with regard to stability.
In addition, a connector having the first connector device of the connector system is proposed. The connector includes just one of the connector devices, in particular the first connector device, of the connector system. This in particular allows an individual connector to be provided with a single connector device.
It is additionally proposed that the connector include the second connector device. This in particular allows an individual connector to be provided with two of the connector devices.
A connector kit for putting together a connector device is also proposed, having at least one universal module including an optical contact, having at least one first configuration module, and having at least one second configuration module, wherein the connector device is configurable female by the universal module in combination with the first configuration module and configurable male by the universal module in combination with the second configuration module. The connector device could be configured at least as a part, in particular as a submodule, of a connector. The connector device could in particular also comprising the entire connector. The connector could, for example, be configured as an electrical connector. The connector is preferably configured as an optical connector. The connector could also conceivably be configured as a hybrid connector, which is intended to produce both at least one electrical plug connection and at least one optical plug connection. The connector device could, for example, be configured as an electrical connector device. The connector device is preferably configured as an optical connector device. The connector device could also conceivably be configured as a hybrid connector device. In particular, the connector device could be part of a common connector, which could for example be configured, without being limited thereto, as a ruggedized connector. The connector devices could also each be part of a separate connector and pluggable together, for example. An assembled state corresponds in particular to a prefabricated, in particular operational, state, specifically in particular in connection with a cable. The first universal module of the first connector device and the second universal module of the second connector device are of mutually identical configuration, wherein the first universal module could differ from the second universal module for example with regard to manufacturing tolerances or the like. Regardless of the connector gender defined by the first configuration module and the second configuration module when assembled, the connector device includes the universal module. The universal module includes an optical contact, which is configured in particular as a ferrule. The optical contact could conceivably alternatively or additionally be configured as a lens and/or as a lens contact. The universal module could for example comprise at least one component which holds the optical contact when assembled. “Intended” should be understood to mean specially designed and/or equipped. Where an item is intended for a specific function, this should be understood to mean that the item fulfills and/or performs this specific function in at least one application state and/or operating state. In particular, improved properties with regard to flexibility may be achieved with a connector kit configured in this way.
A method for putting together a connector device, in particular the connector system is additionally proposed, in particular using a connector kit, having at least one universal module including an optical contact, having at least one first configuration module, and having at least one second configuration module, wherein the connector device is alternatively configured female by the universal module in combination with the first configuration module or configured male by the universal module in combination with the second configuration module.
