Definitions
- the invention relates to a coupling that is set up to accommodate two plug connectors that face one another and make direct electrical contact with one another, each of which has at least one fastening means for fastening to a mating connector. It also relates to a connector arrangement with such a coupling and with a first connector and a second connector.
- Wiring harnesses for motor vehicles are known from the prior art. These cable harnesses can have a plug connector or a cable harness connector at one end, which has a housing with contact cavities, contact elements being fitted in the contact cavities. Some or all of these contact elements can be designed as female contact elements, e.g. as socket contact elements.
- the connector can be connected to a mating connector, e.g. to an interface of a control unit.
- the mating connector has mating contact elements that are designed to complement the contact elements of the connector. If a female contact element is provided on the side of the connector, then a male contact element is provided on the side of the mating connector, e.g. a contact blade or a contact pin.
- Such a cable harness connector or connector is known from DE 10 2004030 991 A1.
- connectors often also have at least one fastening means in order to be mechanically coupled to the complementary mating connector in a captive manner. This is important, for example, in the case of connectors in motor vehicles, so that the electrical connection is not unintentionally disconnected.
- Known connectors that have a high number of contact elements (for example, more than five contact elements or more than ten contact elements or more than 50 contact elements).
- transmission mechanisms can be provided, for example in the form of lever elements and/or slide elements. These elements have a fastening means, for example in the form of a slotted track or a gear.
- these fastening means When they are plugged together, these fastening means then interact with corresponding mating connector fastening means, for example in the form of a bolt, pin or projection or in the form of a toothed rack.
- the plug connector can be connected to the mating plug connector, for example a male connector of a control device, with little operating force, for example by means of a suitable lever design and/or design of the link track.
- the fastening means can bring about a captive coupling between the connector and mating connector in their end position.
- a connector is known from DE 10 2013 212 914 A1, which has a fastening means in the form of a lever element with a single-tooth gear wheel, which meshes with a mating connector fastening means in the form of a toothed rack.
- the plug connector and the mating connector are captively coupled to one another by an interaction of the fastening means and the mating connector fastening means.
- DE 195 11 225 A1 discloses a connector which has a fastening means in the form of a slide element with a plurality of link tracks, the link tracks interacting with pins or bolts or projections as mating connector fastening means.
- the plug connector and the mating connector are captively coupled to one another by an interaction of the fastening means and the mating connector fastening means.
- a connector is known from DE 10 2005 047349 A1, which has a lever element as the fastening means, which has two link tracks which interact with pins as mating connector fastening means.
- a connector which has a slide member with a rack and a gear as a fastener, wherein the Rack meshes with the gear, the gear on its side facing away from the rack meshes another rack, which serves as a mating connector fastening means.
- female contact elements of the connector are pushed onto male contact elements of the mating connector when mating.
- the invention is based on the finding that there can be situations in which the connector or the cable harness connector is to be plugged together with a mating connector which has at least one female contact element, so that in this case a female contact element of the connector meets a female contact element of the mating connector.
- a situation can occur, for example, when two cable harness plugs of the same type are to be coupled to one another, for example in order to lengthen a cable harness section.
- Other applications can be mating interfaces that have been converted from male contact elements to female contact elements. Electrical contacting is not readily possible in such cases. In these cases it is necessary to equip the connector with male contact elements (or at least one male contact element), which can then be plugged together with the corresponding female contact elements of the mating connector and are thus electrically contacted.
- Such connectors which have to be equipped with male contact elements, are only required in relatively small numbers in motor vehicles, for example, since most control units and other components usually have a male connector with male contact elements as the electrical interface or individual male contact elements for provide contacting.
- a clutch is proposed.
- the coupling is set up to accommodate two plug connectors that face one another and make direct electrical contact with one another, each of which has at least one fastening means for fastening to a mating connector.
- the clutch has a housing extending along an axial direction. The housing has a first end and a second end opposite thereto. The clutch also has an interior space. The interior can be an interior of the housing, for example. At the first end of the housing, a first opening is provided for inserting a first connector having a first Has fasteners. The first opening can also be set up for plugging in the first connector.
- a second opening is provided at the second end of the housing for the insertion of a second plug connector which has a second fastening means. The second opening can also be set up for plugging in the second connector.
- a first coupling fastener is disposed at the first end. This is set up to interact with the first fastening means of the first connector in such a way that the first connector can be coupled captively to the coupling or is coupled captively when the first connector is plugged into the coupling in its intended position or in its intended position with the clutch is connected.
- a second coupling fastener is located at the second end. This is set up to interact with the second fastening means of the second connector in such a way that the second connector can be coupled to the coupling in a captive manner, or is coupled in a captive manner when the second connector is plugged into the coupling in its intended position or in its intended position connected to the clutch.
- the captive coupling of the two connectors to each other is thus indirectly achieved in that the coupling provides the two coupling fasteners, by means of which one of the connectors can be captively coupled to the coupling (in the example, the coupling would then have two female-type fasteners the connector have complementary male-coupling fasteners or vice versa, mixed forms are also possible: one coupling fastener is of the female type, the other of the male type).
- a device or a component is thereby advantageously provided which enables a clear cost reduction for the provision of the above-described applications (eg extension cables for cable harnesses or with multi-pole plugs). Because it is advantageously possible by means of the coupling, e.g.
- the coupling makes it possible to reduce the costs for the second plug-in connector for such extension lines, which is only required in small numbers and is laborious to produce, in that the mechanical interface functions are taken over by the coupling.
- the coupling acts, for example, like a kind of adapter, but preferably without an electrical function and/or without electrical lines. It can be designed in such a way that it only provides the mechanical counter-interfaces for the connectors by means of its housing and enables direct contacting between the two connectors in its interior.
- a radial direction is perpendicular to the axial direction.
- a direction of rotation revolves around the axial direction.
- the coupling itself can be manufactured very easily and inexpensively, e.g. from an insulating plastic.
- it can be made by injection molding.
- it can be made from a (metal) sheet or another material with good electrical conductivity.
- the coupling can also advantageously bring about a shielding effect with regard to the electrical connection, which is formed in its interior when the plug connectors are plugged in.
- it is possible to design the coupling as a connecting component.
- it can be partially made of plastic, which enables electrical insulation (e.g. in the area of direct electrical contact between the two connectors. It can also partially have metal, e.g. to provide shielding.
- the housing can be designed like a sleeve, for example. It can, for example, have a first plug-in collar at the first end.
- the first coupling fastening means can be attached or arranged on the first plug-in collar.
- the shape of the first plug-in collar can be analogous to the plug-in collar or the plug-in interface of the plug-in connector corresponding to the first Be designed mating connector.
- the first plug connector can be captively coupled to the coupling at the first end without any problems.
- the housing can, for example, have a second plug-in collar at the second end.
- the second coupling fastening means can be attached or arranged on the second plug-in collar.
- the shape of the second plug-in collar can be analogous to that of the plug-in collar or the plug-in interface of the mating connector corresponding to the second plug-in connector.
- the second connector can be captively coupled to the coupling at the second end without any problems.
- the clutch can have a single first clutch fastening means or a single second clutch fastening means. However, it can also have several, e.g. two, three, four or even more first and/or second coupling attachment means. If a plurality of first and/or second coupling attachment means are provided, they can all be configured the same or differ from one another, for example in order to interact with different first and/or second attachment means of the first or second connector. They can also cause different holding functions (radial, axial, etc.), so that there can be a separation of functions.
- the first opening and the second opening can, for example, each be aligned parallel to the axial direction, facing away from each other.
- the openings it is also possible for the openings to be arranged at an angle to one another, as long as a direct connection of contact elements arranged in the two plug connectors to one another is made possible.
- the housing is designed to be rigid and/or rigid.
- the housing is not just an elastic silicone sleeve, for example, or a sheathing of a connection between the two connectors with insulating tape ("tape") or something similar.
- tape insulating tape
- the first coupling fastening means or coupling fastening element is designed to enter into a form-fitting and/or force-fitting and/or friction-locking connection with the first fastening means. This advantageously enables a particularly simple and reliable coupling to be produced between the coupling and the first plug connector. Such a coupling can preferably be detached without being destroyed, e.g. for maintenance purposes.
- the second coupling attachment means or coupling attachment element is designed to enter into a positive and/or non-positive and/or frictional connection with the second attachment means. This advantageously enables a particularly simple and reliable coupling to be produced between the coupling and the second plug connector. Such a coupling can preferably be detached without being destroyed, e.g. for maintenance purposes.
- the first coupling fastening means is designed as a bolt or pin or projection protruding outwards or inwards.
- the first clutch attachment means can alternatively be designed as a toothed rack.
- the bolt or spigot or projection or the toothed rack is/are set up to interact with a first fastening means designed as a lever element or as a slide element for captive coupling between the coupling and the first plug connector.
- “Protruding outwards” can be understood, for example, as protruding in the radial direction away from the interior, for example from an outside of the housing into an exterior of the clutch. “Protruding inward” can mean, for example, protruding radially inward into the interior, for example starting from an inside of the housing. It goes without saying that several of the above-mentioned elements (bolts, pegs, projections, toothed racks) can also be provided as coupling fastening means that act with one another. Different first coupler fasteners may also be provided at different locations on the first end.
- first coupling fastener e.g. exactly one bolt, etc.
- a plurality of first coupling fasteners e.g. two, three, four or even more
- bolts, etc. can also be provided. These can also be located on different sides of the housing or all on the same side.
- This advantageously enables a particularly simple and secure coupling between the first plug connector and the coupling. Furthermore, this can advantageously also result in a low operating force when plugging the first connector and second connector together, analogous to such a reduction in operating force when plugging together with the mating connector actually provided for the first connector (e.g. a control unit interface with a plug-in collar).
- the second coupling fastening means is designed as a further bolt or further pin or further projection protruding outwards or inwards.
- the second clutch attachment means can alternatively be designed as a further toothed rack.
- the additional bolt or additional pin or additional projection or the additional toothed rack is/are set up to interact with a second fastening means designed as an additional lever element or additional slide element for captive coupling between the coupling and the second plug connector.
- This advantageously enables a particularly simple and secure coupling between the second plug connector and the coupling. Furthermore, this can advantageously also result in a low operating force when plugging the first connector and second connector together, analogous to such a reduction in operating force when plugging together with the mating connector actually provided for the second connector (e.g. a control unit interface with a plug-in collar).
- a further development provides for a stop to be provided in the interior of the housing, with the stop being set up to block displacement of the first connector and/or the second connector along their respective insertion direction beyond the stop.
- the stop also advantageously provides haptic feedback for a fitter that the correct position has been reached. Provision can be made for the stop to be designed to be movable in the interior. This means that it can initially hold the plugged-in connector in a pre-assembly position.
- a (movable) stop of this type can also be designed, for example, to specify an end stop position that has another Blocked or prevented displacement of the respective connector along the respective insertion direction.
- a single stop may be provided in the interior.
- a separate stop can be provided in the interior for each connector, or one or more stops can be provided in the interior for each connector.
- the coupling fasteners can also serve as a stop or the wall of the housing of the coupling or its end face - these elements are often not arranged in the interior or cannot be assigned to the interior (end faces, etc.).
- a further development provides that a base plate is provided in the interior, the base plate extending essentially along a radial direction which runs perpendicular to the axial direction, the base plate being viewed along the axial direction from the first opening and from the second opening is spaced at least 20% of a length of the interior space.
- the base plate can also advantageously serve as a stop, for example, which represents a maximum end position for the first connector and/or the second connector.
- the base plate can represent a type of partition or seal between the first end and the second end. It can, for example, largely form a closed surface in the interior of the housing. It can, for example, divide the interior into a first section (from the first end to the floor panel) and into a second section (from the second end to the floor panel). The penetration of dirt, dirt or fluid media from the first section into the second section and vice versa is made more difficult or even prevented by the base plate.
- the base plate has at least one through-opening for leading through a contacting section of a male contact element, in particular a pin or a contact blade, of the first plug connector and/or for leading through a contacting section of a male contact element, in particular a pin or a contact blade , the second connector.
- the through-opening also has the advantageous effect that the male contact element is radially guided or that when the plug connector, which has the male contact element, is plugged in, it can be seen haptically (possibly also visually from the other opening of the coupling) whether This connector has been inserted in the correct radial position so that the male contact element actually meets the corresponding female contact element.
- the base plate with the through-opening thus advantageously serves as a kind of positioning aid.
- the base plate can have exactly one through-opening. However, it can also have a plurality of through-openings. For example, it has a through-opening for each male contact element.
- the through-opening has a diameter that is only slightly larger (e.g. at most 20% larger or at most 10% larger) than a contacting section of the male contact element, with the contacting section passing through the through-opening and the corresponding female - Contact element contacted on the other side of the base plate.
- the through-opening has an insertion bevel or an insertion funnel on the side facing the male contact element, so that the contacting section is "captured" when the connector is plugged into the first opening and then the contacting section by means of the insertion bevel or .of the insertion funnel is directed into the passage opening.
- the through-opening it is also possible for the through-opening to have an insertion bevel on both sides of the base plate. In this way, the coupling can be used advantageously for any plug-in direction of male contact elements.
- the constriction of the through-opening between two such insertion bevels advantageously causes a radial positioning of an inserted male contact element.
- a seal can also advantageously be provided in the through-opening or on the base plate, i.e. upstream or downstream of the through-opening viewed in the axial direction. In this way, a sealing effect of the base plate between the first section and the second section is advantageously further improved.
- each of the two connectors can have at least one male contact element which can be connected to a corresponding female contact element of the respective other connector.
- the second connector has male contact elements and the first connector only has female contact elements.
- a further development provides that a first seal is provided at the first end, which is set up, in cooperation with the first plug connector, to seal off the interior space from the first opening against the outside environment of the coupling.
- Such an environment can be, for example, an engine compartment of a motor vehicle.
- the first seal can alternatively or additionally also be arranged on the first connector and then is inserted together with the first connector into the interior of the coupling or the housing and the seal is ensured in this way.
- a second seal is provided at the second end, which is set up, in cooperation with the second plug connector, to seal the interior space from the second opening against the outside environment of the coupling.
- the second seal can alternatively or additionally also be arranged on the second connector in an equivalent manner and is then inserted together with the second connector into the interior of the coupling or the housing and the seal is ensured in this way.
- At least one fastening device is provided on the housing for fastening the coupling to another element, in particular on or in a wall.
- the coupling can advantageously be stabilized: an electrical connection created in its interior by plugging in the first connector and second connector and/or the captive coupling of the connectors on the coupling are advantageous against unintentional movements by fastening the coupling to an external element Protected against ingress of dirt, dirt and moisture (e.g. if the coupling is lying on the floor or would fall on the floor).
- the provision of the fastening device advantageously provides a defined element by means of which the coupling is to be fastened. An improvised assembly of the coupling on another element by e.g. one of the Coupling fastening means would be damaged or covered can be advantageously avoided.
- a further development provides that a first section of the interior space, in which the first connector can be accommodated, has a first cross section, with a second section of the interior space, in which the second connector can be accommodated, having a second cross section, with the first cross section and second cross-section have an identical shape or have mirror-symmetrical shapes to one another.
- the clutch can be produced particularly simply and inexpensively.
- the coupling can be used equally from both openings. Incorrect alignment, e.g. in the case of automated coupling of the connectors or in the case of assembly under poor visibility conditions (e.g. in an engine compartment), can thus be advantageously avoided.
- the quality of the assembly is advantageously increased.
- the time required for assembly is advantageously reduced. In this way, it is also advantageously possible to use two identical connector housings for the first connector and the second connector. As a result, considerable costs can advantageously be saved.
- the connector arrangement has a first connector, a second connector and a coupling as described above.
- the first connector has a first connector housing with a first contact cavity and a female contact element arranged in the first contact cavity.
- the first connector has a first attachment means. This can only be configured or formed, for example, as a lever element and/or as a slide element.

- the second plug connector is plugged into the interior through the second opening and is captively coupled to the coupling by means of a coupling between the second fastening means and the second coupling fastening means.
- the male contact element of the second connector is electrically connected to the female contact element of the first connector. It can be plugged together with the female contact element, for example.
- Harness connector is provided.
- such an extension cable can have two identical plug connectors at both ends, so that standard parts can be used at low cost.
- the use of similar connector housings can be made possible, or it is possible to connect two connectors, which could not be coupled to one another due to their geometry, in a cost-effective manner with one another electrically and mechanically in a captive manner.
- the cost-intensive production of corresponding mating connector housings for the first connector and/or the second connector can advantageously be made superfluous.
- the direct electrical contact between the first connector and the second connector advantageously avoids the need for additional contact points to be formed, e.g. in an adapter piece with its own electrical lines.
- the connector arrangement is thus advantageously space-saving and offers safe and reliable, low-resistance electrical contact. At the same time, it is designed to be mechanically captive and therefore robust, even if two connector housings which are normally mechanically incompatible or cannot be directly coupled to one another in a captive manner are part of the connector arrangement.

Furthermore, it is possible that the first connector additionally has a single or multiple male contact elements. These can, for example, also be mounted or arranged in corresponding first contact chambers.

- second connector it only has to be fitted with contact elements which are designed to complement the contact element of the first connector or the contact elements of the first connector.
- the use of a mirror-symmetrical housing also enables the contact elements to meet with a precise fit when the two connectors are placed on top of one another with their connector faces, since the mirror symmetry avoids chirality.
- the second connector housing is designed to be mirror-symmetrical, in particular along a second longitudinal axis.
- first connector housing and the second connector housing are designed as identical parts.

- the second plug connector 200 has a second fastening means 210, which is designed here, for example, as a further lever element 211.
- the first plug connector 100 is inserted through the first opening 6 into the interior space 5 and is captively coupled to the coupling 1 as the first coupling fastening means 8 by means of a coupling between the lever element 111 and the two bolts 18 shown here.
- the second plug connector 200 is inserted through the second opening 7 into the interior 5 and can be coupled captively to the coupling 1 as a second coupling fastening means 9 by means of a coupling between the further lever element 211 and the two further bolts 19 shown here.
- the second connector 200 has not yet been finally coupled, but the fully coupled state would appear here, for example, analogously to the state of the first connector 100 on the left-hand side of FIG. 1 .
- the two male contact elements 203 of the second connector 200 are directly electrically connected to the two female contact elements 103 of the first connector 100 .
- the male contact elements 203 are then inserted into the female contact elements 103 or plugged together with them.
- the female contact elements 103 here have, for example, a first crimp section 104 facing away from the interior 5, in which a first insulation crimp 107 and a first line crimp 108 are arranged.
- the male contact elements 203 each have a second crimping section 204 facing away from the interior space 5, in which a second insulation crimp 208 and a second line crimp 208 are arranged.
- a cable 60 is attached to each female contact element 103 or male contact element 203 and is electrically connected to the respective contact element 103, 203.

- Each second latching lance 206 can engage behind a second undercut 230 of the second connector housing 201 when the male contact element 203 has been fitted into its second contact cavity 202 .
- the male contact elements 203 are actually originally designed as female contact elements. With the aid of an adapter pin inserted into the front opening, which acts like a contact blade or pin contact, a male contact element 203 can then be produced in a simple and cost-effective manner from the female contact elements produced in large numbers. In this way, the use of identical parts is further increased, which further reduces the costs for the production of male contact elements that have to be produced separately and thus the costs for the connector arrangement 500 .
- the male contact section 205 would then be the part of such an adapter pin protruding from the female contact element originally designed, for example, as a socket contact element.
- the adapter pin can, for example, have a contact body extending along an adapter pin longitudinal axis with a first adapter pin end facing the (original) female contact element and a second adapter pin end facing away therefrom, as well as at least one means for captive, in particular non-destructively detachable, coupling of the adapter pin with the (original) female contact element.

- the adapter pin (not shown here) can have latching lances that encompass a front end (contact mouth) of the (original) female contact element. This at least one latching lance can then, for example, latch into a recess in a wall of the (original) female contact element and thus couple the adapter pin captively to the (original) female contact element and thus convert it into a male contact element.
- a first housing passage opening 131 is formed for the two contact chambers 102 shown here, through which the contacting section 205 of the male contact element 203 of the second connector 200 can electrically contact the respective female contact element 103.
- the first Housing passage openings 131 can be provided, for example, with an insertion funnel on the side facing the male contact element 203 .

- the first lever element 111 has on each side a first link track 112 facing the first connector housing 101 and into which one of the bolts 18 can engage.
- the first connector 100 can then be pulled into the interior 5 of the coupling 1 by rotating the first lever element 111 .
- the first lever element 111 is shifted into its end position and as a result the first connector is coupled to the coupling 1 in a captive manner.
- the first connector 100 can thus be fastened to the coupling 1 in a captive manner, but at the same time can be detached without being destroyed.
- the first end 3 of the coupling 1 thus acts in the manner of a connector collar of a mating connector that is complementary to the first connector 100 .

- the second lever element 211 can still be seen in its initial position.
- the additional lever element 211 Since the additional lever element 211 partially protrudes from the plane of the drawing or sectional plane, this part of the additional lever element 211 is shown in dashed lines, as is a front part of the additional lever element 211 that delimits the link path the other bolts 19 engage in the second link tracks 212.
- the second connector 200 When the other lever element 211 rotates, the second connector 200 is then pulled into the interior 5 by the interaction of the other bolts 19 with the other or second link tracks 212, so that in the End position of the further lever element 211, the male contact elements 203 contact the female contact elements 103 electrically directly.
- the second plug connector 200 is then secured to the coupling 1 so that it cannot be lost, but at the same time can be detached without being destroyed.
