Description

[0001] The invention relates to a connector receiving device, a connector system and a method for connecting a flat ribbon cable to a connector receiving device.

[0002] Flexible flat cables (FFCs) are widely used in modern electronics. In a flexible flat cable, several conductors run parallel to each other along a common plane defined by the conductors. Each conductor is surrounded by insulating material, forming a wide, planar cable. Due to this unique cable geometry, special cable connectors have been designed to efficiently connect these cables to, for example, printed circuit boards. A secure fit of such a cable must be guaranteed, even in demanding applications. To this end, connection systems have been developed to ensure a particularly secure fit of the cable within the connector.However, a common problem is the high stress placed on the cable when inserting it into the cable socket, which can lead to damage to the cable, potentially impairing a secure fit and / or a reliable contact connection.

[0003] It is therefore the object of the present invention to provide a plug receptacle, a connector system and a method for connecting a flat ribbon cable to a plug receptacle device which achieves improved connection security and reduces stress on the flat ribbon cable when connecting to the plug receptacle.

[0004] The problem is solved by the subject matter of the independent claims.

[0005] Preferred embodiments are the subject of the dependent claims.

[0006] One aspect of the invention relates to a connector receiving device for receiving an end section of a ribbon cable, comprising: a receiving body having: an opening; a guide section for guiding the end section of the ribbon cable in the opening; and two receiving retaining elements for holding at least a part of a plug-in device located on the end section of the ribbon cable in a received state of the ribbon cable; wherein the guide section and the two receiving retaining elements cause an elastic deformation of at least a part of the plug-in device when the ribbon cable is inserted into the opening of the connector receiving device, wherein, in the received state of the ribbon cable, the at least part of the plug-in device of the ribbon cable essentially retains its original shape. In other words, the elastic deformation disappears in the received state of the ribbon cable.The deformation is essentially reversed upon reaching the recorded state, i.e., the insertion device essentially returns to its original shape or has already returned to it in this state.

[0007] A flat ribbon cable that can be received by the connector receptacle can, in particular, comprise a plurality, for example two, three, four, five or more, adjacent conductors, each of which is surrounded by insulating material and connected to one another. Preferably, the conductors are arranged side by side, so that the flat ribbon cable has a substantially flat and / or planar cross-section. At one end region, the flat ribbon cable can have a plug-in device comprising an exposed and / or contactable contact surface for each conductor. Preferably, the contact surfaces are arranged substantially side by side and oriented in the same direction, a preferred direction being orthogonal to the plane of extension of the flat ribbon cable.

[0008] The insertion device for the ribbon cable is preferably, in its original form, particularly in a state not yet received by the receiving device, substantially planar and / or comprises a substantially planar surface section. In the received state, the insertion device preferably retains its original form, wherein the original form is, in particular, a form which the insertion device retains substantially without external force.

[0009] The receiving body of the connector receptacle has an opening for receiving at least part of a ribbon cable, whereby during receiving and / or insertion only a small or essentially no contact normal force is exerted on the contact surfaces of the insertion device by the connector receptacle.

[0010] Preferably, the receiving body enables the insertion of the insertion device by essentially translational displacement of the insertion device in an insertion direction, wherein the insertion device is oriented in particular essentially in the extension direction of the flat ribbon cable.

[0011] The receiving body has two or more, for example three or four, receiving retaining elements, each of which is designed to engage with at least one part of the insertion device.

[0012] To achieve the received state, at least a portion of the ribbon cable, in particular a portion of the insertion device, is elastically and / or substantially reversibly deformed. Preferably, the receiving retaining elements are positioned and / or designed such that when the insertion device is moved into the opening and / or within the opening in the insertion direction, at least a portion of the insertion device is deformed.

[0013] In particular, the guide section can be positioned and / or designed such that it at least limits or substantially prevents the insertion device from shifting in a direction orthogonal to the plane of extension of the ribbon cable. The guide section can have a guide surface which is preferably on the same plane as the upper surface of the receiving elements, which is oriented parallel to the plane of extension of the ribbon cable. To prevent deformation of the insertion device, the distance between the guide section and the upper surface of the receiving elements, measured orthogonally to the plane of extension of the ribbon cable, is preferably less than the thickness and / or height of the insertion device.Alternatively, the guide section can be positioned closer in some areas to the wall of the opening opposite the guide section than a side of the receiving retaining elements pointing in the opposite direction, thereby achieving a greater deformation of the insertion device.

[0014] When installed, the receiver does not cause any deformation of the ribbon cable and / or the connector. This prevents permanent deformation and / or stress on the connector, thus preventing premature material fatigue.

[0015] The receiving body can be designed to prevent the end section of the ribbon cable from shifting out of the received state.

[0016] Preferably, non-destructive displacement of the ribbon cable, in particular the insertion device, from its received position is prevented by applying force to the ribbon cable in the opposite direction of insertion. By engaging the receiving retaining elements with at least part of the insertion device, displacement of the insertion device in the opposite direction is essentially prevented, or at least significantly impeded.

[0017] Preferably, however, the engagement can be released and the ribbon cable and / or the insertion device pulled out of the connector receptacle essentially non-destructively by manipulation and / or elastic deformation of at least a part of the insertion device, in particular essentially orthogonal to the plane of extension of the ribbon cable and / or the insertion device. For example, the receptacle body has one or more recesses through which at least a part of the insertion device is accessible, in particular for manipulation and / or elastic deformation, especially by means of a tool such as a screwdriver.

[0018] A surface of the guide section defining the opening and a surface of the receiving retaining elements defining the opening can be essentially opposite to each other and lie essentially on one plane, the plane preferably being essentially parallel to the extension plane of the ribbon cable and / or the insertion device.

[0019] In other words, the guide section and the receiving retaining elements can have surfaces that point in opposite directions and / or are designed to rest against substantially opposite sides of the ribbon cable and / or the plug-in device.

[0020] The guide section and the receiving elements can be designed, in particular, to cause elastic deformation of the insertion device when the insertion device is moved into and / or within the opening. The orientation in opposite directions prevents, in particular, the insertion device from deflecting, thus avoiding elastic deformation.

[0021] Preferably, each of the two receiving elements is designed to engage with a wing section of the flat cable insertion device when the cable is received. This allows for advantageous engagement of the connector receiving device with the flat cable. In particular, a substantially centered alignment and / or prevention of tilting of the insertion device can be advantageously achieved in this way.

[0022] The receiving elements are preferably provided on opposite sides of the connector receiving device and configured to engage with a wing section extending perpendicular to the direction of extension of the ribbon cable in the plane of extension of the ribbon cable. The wing sections can, in particular, project in opposite directions.

[0023] Preferably, each of the two receiving elements has a guide ramp for guiding one wing section of the flat ribbon cable insertion device into the received position. This facilitates elastic deformation when guiding the insertion device in and / or into the opening.

[0024] In particular, the guide ramps of the receiving elements are designed to cause progressive elastic deformation, especially bending, of the wing sections of the flat ribbon cable as the insertion device is progressively moved in the insertion direction.

[0025] Preferably, the guide section includes a central guide ramp for guiding the insertion device of the ribbon cable into the received position and / or for guiding it when the ribbon cable is moved in the insertion direction within the opening and / or into the opening. This allows for advantageous centering of the insertion device and thus facilitates insertion of the ribbon cable into the receiving body.

[0026] Preferably, the connector receptacle comprises a main body that can be arranged on a printed circuit board and connected to the receiving body; the receiving body being detachably movable relative to the main body. This advantageously allows the ribbon cable to first be received by the receiving body of the connector receptacle while the receiving body is not connected to the main body and / or the printed circuit board. The ribbon cable can then be secured to the printed circuit board by connecting the receiving body to the main body. This is particularly advantageous when there is insufficient space or the mobility of the ribbon cable is so restricted that a direct connection of the ribbon cable to the receiving body arranged on the printed circuit board is not possible or only possible with difficulty.

[0027] Preferably, the main body has at least one contact element which can be connected to a contact surface of the plug-in device and can establish an electrical and / or physical connection. By connecting the main body to the receiving body, which has the ribbon cable in the connected state, the contact element can be connected to the contact surface of the plug-in device, thus establishing the electrical and / or physical connection.

[0028] By inserting the insertion device into the receiving body while it is not connected to the main body, the insertion device is not subject to any force from the contact device, which advantageously reduces the stress on the ribbon cable, in particular on the insertion device, during insertion.

[0029] The skin body can have two locking devices: one for guiding the receptacle's movement relative to the main body and the other for essentially locking the receptacle's movement relative to the main body in a locking position. This allows the receptacle to be held in a locked position relative to the main body and / or the insertion device to be kept in contact with the contact device, thus ensuring a reliable contact connection.

[0030] Preferably, the ribbon cable in the locking position cannot be pulled out of or detached from the connector receptacle. In particular, manipulation of the wing sections of the insertion device is not possible, so that the engagement of the receptacle retaining elements with the wing sections cannot be released.

[0031] Preferably, access to at least part of the insertion device is prevented by one or more recesses in the receiving body in the locking position. In particular, the one or more recesses of the receiving body in the locking position can be at least partially closed and / or covered by the main body, thus preventing manipulation and / or elastic deformation of at least part of the insertion device.

[0032] The two locking devices can extend from the main body essentially orthogonally to the circuit board and / or be arranged on two opposite side regions of the main body. This allows for stable guidance of the movement of the receiving body and / or locking of the receiving body to the main body.

[0033] The receiving body can have a receiving section associated with the respective locking device, which can engage with the locking device. In particular, the receiving section can include a recess and / or a hole.

[0034] Preferably, the locking device has a movable locking section that allows the receiving body to be moved towards the locking position and prevents, or at least significantly hinders, its movement out of the locking position. This allows the receiving body to be locked easily, in particular by moving it towards the main body until it reaches the locking position. Likewise, the receiving body can be moved away from the main body, in particular by manipulating the locking section. Without manipulating the locking section, the receiving body is held in the locking position and in contact with the main body.

[0035] Preferably, the main body and the receiving body form a positive fit in the locking position, wherein the positive fit is oriented in particular in the insertion direction and / or in the arrangement direction of the locking devices or the receiving retaining elements.

[0036] For example, in the locked position, the receiving body and the main body form a tongue-and-groove connection, wherein the receiving body comprises one or more springs and / or spring sections and the main body comprises one or more grooves. Alternatively, the receiving body comprises one or more grooves and the main body comprises one or more springs and / or spring sections.

[0037] Another aspect of the invention relates to a connector system for connecting a ribbon cable to a printed circuit board comprising: a connector receiving device as described in the preceding paragraph; and a ribbon cable in a state received by the connector receiving device.

[0038] Preferably, the receiving body is in a locking position, wherein one or more contact surfaces of the insertion device of the ribbon cable are in contact with one or more contact devices of the connector receiving device.

[0039] Preferably, the receiving body of the plug receiving device is substantially locked relative to the main body by one or more locking devices.

[0040] Another aspect of the invention relates to a method for connecting a ribbon cable to a connector receiving device comprising: providing a receiving body of the connector receiving device for receiving at least a part of the ribbon cable; inserting a plugging device of the ribbon cable into an opening of the receiving body; wherein, in the received state of the ribbon cable, the at least part of the plugging device of the ribbon cable essentially retains its original shape.

[0041] In particular, the method has the advantage that when the insertion device is inserted into the receiving body, no force is exerted on the insertion device by a contact element of the connector receiving device. Preferably, the method comprises moving the receiving body with the ribbon cable in the received state towards and / or locking the receiving body with the ribbon cable in the received state to a main body of the connector receiving device arranged on a printed circuit board. Thus, after the insertion device has been received by the receiving body, in a further, separate step the received insertion device is connected to the contact element, and an electrical and / or physical connection is established between the ribbon cable and the printed circuit board.

Brief description of the drawings

[0043] Figure 1 shows an exemplary connector system; Figure 2 shows an exemplary connector receptacle and a ribbon cable to be received; Figure 3 shows a receiving body of an exemplary connector receptacle; Figure 4 shows a sectional view of the Figure 3 shown receiving body with a flat ribbon cable received by it. Detailed description of the drawings

[0044] The Figure 1 Figure 1 shows an exemplary connector system 1 comprising an exemplary connector receiving device 30 and a ribbon cable 20 in a state received by the connector receiving device 30.

[0045] In this example, the connector receptacle 30 comprises a main body 32, which is arranged on a circuit board 10, and a receiving body 34, which is connected to the main body 32 and / or is in a locking position relative to the main body 32.

[0046] Two locking devices 50 are provided for locking the receiving body 34 and / or holding the receiving body 34 in the locking position; these devices are connected to the main body 34. Alternatively or additionally, the locking devices 50 can be directly connected to the circuit board 10, in particular by a metallurgical bond.

[0047] Preferably, the locking devices 50 project from the main body 32 in a direction orthogonal to the printed circuit board 10 and / or to the plane of extension of the ribbon cable 20. Preferably, the locking devices 50 have a height of between about 5 mm and about 25 mm, in particular between about 7 mm and about 10 mm, for example about 8.3 mm, where height means the distance of a distal end region of the locking devices 50 measured from the plane of the printed circuit board.

[0048] Alternatively, the locking devices 50 can extend essentially parallel to the printed circuit board 10. This is particularly advantageous if the extension direction of the end region of the ribbon cable 20 is essentially orthogonal to the printed circuit board 10.

[0049] The locking devices 50 can have one or more, in particular two, locking sections 52, which are designed to be elastically displaceable and / or deformable and essentially prevent displacement of the receiving body 34 in the locking position. Preferably, the locking sections 52 are designed to essentially prevent, or at least limit, displacement of the receiving body 34 only by force acting on the receiving body 34.

[0050] Advantageously, the locking sections 52 are designed and arranged in such a way that they can be elastically displaced and / or deformed by manipulation in order to allow the receiving body 34 to be displaced relative to the main body 32.

[0051] In the example shown, a distal end region of the locking section 52 can be displaced and / or deformed in a direction parallel to the circuit board 10 and towards the opposite locking device 50 in order to release the receiving body 34.

[0052] In addition to an exemplary connector receptacle 30, the connector system 1 further comprises a ribbon cable 20, which is received by the connector receptacle 30, in particular by the receiving body 34. The ribbon cable 20, in particular an extension plane of the ribbon cable 20, can be oriented essentially parallel to the printed circuit board 10.

[0053] Preferably the ribbon cable 20 comprises a plug-in device 22 at an end region, wherein the plug-in device 22 is configured to come into contact with the plug receiving device 30 and / or to be received by the plug receiving device 30.

[0054] In the example shown, the ribbon cable 20 is in a received state, wherein the insertion device 22 is at least partially received and / or positioned in an opening 36 of the connector receiving device 30, in particular of the receiving body 34.

[0055] In the received state of the connecting cable 20 and in the locking position of the receiving body 34, displacement of the connecting cable 20 is essentially prevented, in particular the removal of the insertion device 22 from the opening 36 of the receiving body 34, as described in detail elsewhere.

[0056] Preferably, access to at least part of the insertion device 22 is prevented by one or more recesses in the receiving body 34 in the locking position. In particular, the one or more recesses in the receiving body 34 can be at least partially closed and / or covered by the main body 32 in the locking position, thus preventing manipulation and / or elastic deformation of at least part of the insertion device 22.

[0057] The Figure 2 shows an exemplary connector receptacle 30 and a flat ribbon cable 20 that can be received by it.

[0058] The connector receiving device 30 can comprise a receiving body 34, which is configured to receive at least a portion of the ribbon cable 20. For this purpose, the connector receiving device 30 preferably has an opening 36 in the receiving body 34, which can receive an insertion device 22 of the ribbon cable 20 and / or into which an insertion device 22 of the ribbon cable can be inserted, at least partially, by moving it in an insertion direction E.

[0059] The receiving body 34 is preferably designed such that it engages with a received insertion device 22 and / or a flat ribbon cable 20 in the received state in such a way that displacement of the insertion device 22 and / or the flat ribbon cable 22, in particular against the insertion direction E, is essentially prevented, or at least limited.

[0060] For this purpose, the receiving body 34 can have one or more, for example two, receiving retaining elements 40, each of which forms a positive fit with a part of the insertion device 22, in particular parallel to the extension plane of the flat ribbon cable 20.

[0061] Preferably, the receiving retaining elements 40 are arranged on opposite sides of the opening 36 and are designed to engage with a retaining wing 24 of the insertion device 22.

[0062] The retaining wings 24 can extend in opposite directions transversely to the insertion direction E and in the plane of extension of the ribbon cable 20. The receiving retaining elements 40 can each have a surface pointing in the insertion direction E, against which a section of a retaining wing 24 pointing opposite to the insertion direction E can abut in order to form the positive locking in the received state of the ribbon cable 20.

[0063] The receiving body 34 is preferably designed such that, when the insertion device 22 is inserted, the receiving body 34, in particular the receiving retaining elements 40, elastically deforms at least a part of the insertion device 22. For this purpose, the receiving retaining elements 40 can each include a guide ramp 42 for guiding and / or elastically displacing the retaining wings 24.

[0064] For example, the guide ramp 42 can be aligned at an angle to the circuit board 10 and / or to the extension plane of the ribbon cable 20 and rise in the insertion direction E and / or into the cavity of the opening 40.

[0065] The guide ramp 42 is preferably located opposite one of the surfaces of the receiving holding element 40 that form the positive locking connection, so that the guide ramp 42 displaces and / or deforms a holding wing 24 in order to pass and / or overcome the receiving holding element 40 and to enter the received state.

[0066] In particular, the receiving retaining elements 40 and / or the guide ramps 42 are designed and / or arranged to produce a substantially symmetrical and elastic deformation of the insertion device 22, wherein, in the received state of the flat ribbon cable 20, the insertion device 22 essentially retains its original shape. Preferably, the insertion device 22 exhibits substantially no structural change in the received state compared to its original shape.

[0067] To achieve an advantageous deformation of the insertion device 22, the receiving body 34 can have a guide section 46 which is configured to guide at least a part of the insertion device 22 in the opening 36 and / or inside the cavity. In particular, the guide section 46 is configured and / or arranged in such a way as to substantially prevent, or at least limit, the displacement of a part of the insertion device 22 in a direction orthogonal to the plane of extension of the ribbon cable 20.

[0068] The guide section 46 is preferably arranged in a middle and / or central area between the receiving retaining elements 40 and is designed to support the insertion device 22 in such a way that a middle and / or central area of ​​the insertion device 22 is essentially not displaced and / or deformed during insertion.

[0069] In particular, the guide section 46 can comprise a guide surface which is oriented essentially parallel to the circuit board 10 and / or the extension plane of the ribbon cable 20 and is directed opposite to the direction of displacement and / or deformation of the wing sections 24.

[0070] The guide surface of the guide section 46 is preferably on the same plane as the upper surface of the receiving elements 40, which is oriented parallel to the plane of extension of the ribbon cable 20. At least the distance between the guide surface of the guide section 46 and the upper surface of the receiving elements 40, orthogonal to the plane of extension of the ribbon cable 20 and / or the printed circuit board 10, is less than the thickness and / or height of the insertion device 22. Alternatively, the guide section can be arranged in certain areas closer to the wall of the opening opposite the guide section than a side of the receiving elements pointing in the opposite direction, thereby achieving a greater deformation of the insertion device.

[0071] By the interaction of the receiving retaining elements 40 and / or the guide ramps 42 with the guide section 46, an advantageous deformation, in particular a convex curvature, of at least a part of the insertion device 22 can be achieved.

[0072] The deformation essentially reverses itself upon reaching the received state and / or the insertion device 22 essentially regains its original shape in the received state. Preferably, in the received state, no force deforming the insertion device 22 acts on it from a receiving retaining element 40 and / or a guide ramp 42 and / or the guide section 46.

[0073] Preferably, the connector receptacle 30 comprises a main body 32, which can be arranged on a printed circuit board 10 and to which the receptacle 34 can be connected. The main body 32 can have one or more contact devices 58 for forming an electrical and / or physical contact connection with one or more conductors of the ribbon cable 20.

[0074] The receiving body 34 is displaceably and / or detachably connected to the main body 32. Preferably, the receiving body 34 is arranged to be displaceable substantially translationally and parallel to the circuit board 10 relative to the main body 32. The receiving body 34, with the flat ribbon cable 20 inserted and preferably guided by the locking devices 50, can be displaced towards the main body 32.

[0075] The receiving body 34 can be moved to a locking position, in which the receiving body 34 rests at least partially against the main body 32. In the locking position, an electrical and / or physical contact connection is formed between one or more contact elements 58 of the plug receiving device 30 and one or more contact surfaces of the insertion device 22.

[0076] The receiving body 34 and the main body 32 are designed in such a way that a positive locking connection is formed in the locking position, in particular by at least partial engagement of a spring 56 with a groove 54. In the example shown, the main body 32 includes a groove 54 which engages with a spring 56 of the receiving body when the receiving body 34 is in the locking position.

[0077] The connector receptacle 30 is designed in particular such that, due to the insertion of the ribbon cable 20 by the receptacle body 34, the ribbon cable 20 does not come into contact with a contact element 58 of the connector receptacle 30 and / or no electrical and / or physical contact connection is formed with a contact element 58 of the connector receptacle 30. This is achieved by moving the receptacle body 34 towards a locking position in contact with the main body 34 arranged on the circuit board 10.

[0078] The one or more, in particular three, contact devices 58 can have essentially rod-shaped, preferably curved, sections which are arranged at least partially in recesses of the main body 32. The contact devices 58 are preferably bonded to the circuit board 10. At least one distal end region of the contact devices 58 projects from the main body 32 to form an electrical and / or physical contact connection with a contact surface of the plug-in device 22.

[0079] The Figure 3 Figure 1 shows a receiving body 34 of an exemplary connector receiving device 30. The receiving body 34 can have one or more features of the receiving body 34 of the Figures 1 and 2 exhibit. Likewise, the receiving body 34 of the Figure 3 in the connector system of Figure 1 be used.

[0080] In particular, the receiving body 34 is designed to receive at least a part of a flat ribbon cable 20 and to substantially prevent the received part of the flat ribbon cable 20 from shifting.

[0081] Preferably, the receiving body 34 is designed such that a part of a plug-in device 22 of the flat ribbon cable 20 undergoes elastic deformation when received by the receiving body 34 due to a relative displacement of the receiving body 34 and the plug-in device 22, wherein the elastic deformation essentially reverses itself when the plug-in device 22 is in a state received by the receiving body 34.

[0082] In the received state of the insertion device 22 and / or the ribbon cable 20, a positive locking connection is formed, whereby a relative displacement of the receiving body 34 and the insertion device 22 is essentially prevented, in particular against an insertion direction E.

[0083] However, the receiving body 34 can have one or more recesses through which at least part of the insertion device 22, in particular the wing sections 24, is accessible, allowing manipulation and / or elastic deformation. In particular, at least part of the insertion device 22 can be elastically deformed by means of a tool, such as a screwdriver, especially substantially orthogonal to the plane of extension of the ribbon cable 20 and / or the insertion device 22, in order to release the engagement between the insertion device 22 and the receiving body 34 and to allow the ribbon cable 20 and / or the insertion device 22 to be pulled out of the connector receiving device 30 essentially without damage.Preferably, the recesses are arranged and / or designed in such a way as to prevent manipulation and / or deformation when the receiving body 34 is in a locking position relative to a main body 32.

[0084] To facilitate the displacement of the receiving body 34 relative to a main body 32 of the connector receiving device 30, the receiving body 34 can have one or more, for example two, locking device receiving sections 51, in particular for receiving one locking device 50 of the connector receiving device 30 each. The locking device receiving section 51 can, for example, comprise a through hole and / or a groove and / or a chamfer.

[0085] The receiving body 34 can have one or more receiving retaining elements 40 for engaging with at least a part of the insertion device 22 and / or displacing and / or deforming at least a part of the insertion device 22, in particular wing sections 24 projecting laterally from the insertion device 22. In particular, the receiving retaining elements 40 can have one or more of the features described in the process.

[0086] The receiving body 34 can, in particular, have guide ramps 42, 48 for guiding at least a part of the plug receiving device 30 and / or for displacing and / or deforming at least a part of the insertion device 22 when the insertion device 22 is inserted into the receiving body 34. In particular, the guide ramps 42, 48 can have one or more of the features described in the process.

[0087] The Figure 4 shows a cross-sectional view of the in Figure 3shown receiving body 34 with a flat ribbon cable 20 received by it.

[0088] The flat ribbon cable 20 engages with the receiving retaining elements 40 in such a way that displacement is prevented essentially against an insertion direction E.

[0089] The flat ribbon cable 20, in particular the plug-in device 20, exhibits essentially no deformation in the received state. Any elastic deformation caused during plugging in, affecting at least part of the plug-in device 20, has essentially completely receded.

[0090] The receiving body 34 can have one or more chamfers and / or chamfer sections 56 to form a positive fit with one or more corresponding grooves 54 of the main body 32 in the locking position, preferably orthogonal to a displacement direction of the receiving body 34 towards the locking position.

[0091] In particular, when the ribbon cable 20 is inserted and the receiving body 34 is not in the locking position, the ribbon cable 20 is not in contact with a contact element 58 of the connector receiving device 30. An electrical and / or physical contact connection with a contact element 58 of the connector receiving device 30 is preferably only formed when the receiving body 34 is in the locking position. This reduces the stress on the ribbon cable 20 when connecting it to a connector receiving device 30. Reference symbol list
