Abstract

The present invention relates to a plug connector assembly comprising a plug connector (1) with a plug connector housing (2), a corresponding plug connector (3) with a corresponding plug connector housing (4), an operating element (5), and a CPA (20). In this case, the plug connector (1) has a plugging position relative to the corresponding plug connector (3) and can be mated with the corresponding plug connector (3) along a plugging direction (S) from an initial plugging position (AP) to a final plugging position (EP). The operating element (5) is movable between a first position (P1) and a second position (P2) and is formed to reduce the plugging force when the plug connector (1) is connected to the corresponding plug connector (3). When the operating element (5) moves from the first position (P1) to the second position (P2), the plug connector (1) is moved from the initial plugging position (AP) to the final plugging position (EP). The CPA (20) is movable between an unlocking position (EL) and a locking position (SL). The CPA (20) prevents the operating element (5) from moving from the second position (P2) to the first position (P1) in the locking position (SL). The CPA (20) and the corresponding plug connector (3) are relatively adjusted with respect to each other such that the movement of the CPA (20) from the unlocking position (EL) to the locking position (SL) is blocked in relation to the plugging position.

Description

Technical Field

[0001] Field of the Invention The present invention relates to a plug connector assembly. The present invention further relates to a plug connector for a plug connector assembly. The present invention further relates to a corresponding plug connector for a plug connector assembly.

[0002] Background Art In the area of plug connector assemblies that can be assembled by mating a plug connector with a corresponding plug connector, it is important not to exceed a defined insertion force when mating from an initial insertion position to a final insertion position. In the case of high-polarity plug connectors and / or plug connectors for high-current use, such as plug connectors for electric vehicles, there is a risk that the insertion force exceeds the desired level.

[0003] In order to reduce the insertion force, the plug connector may be provided with an operating element. This operating element is movable between a first position and a second position and is configured to reduce the insertion force when the plug connector is connected to the corresponding plug connector. In this case, when the operating element moves from the first position to the second position, the plug connector is moved to the final insertion position.

[0004] Furthermore, it is known that it can be convenient for the operator if the plug connector assembly has an element that indicates the arrival of the operating element at the second position or an element that can only be moved when the second position is achieved. Such an element is usually referred to as "CPA" ("Connector Position Assurance"). The CPA may be movable, for example, along the moving direction between an unlocked position and a locked position, and at the locked position, it can prevent the operating element from moving from the second position to the first position.

[0005] Based on European Patent Application Publication No. 0933836, German Patent Application Publication No. 102011101205, and International Publication No. 02 / 078126, such plug connectors assemblies with various operating elements are known.

[0006] Disclosure of the Invention The present invention, in particular in high-current connectors and high-polarity plug connections having the operating elements described above, starts from the recognition that the CPA only indicates reaching the second position of the operating element. Thus, the function of the CPA is independent of the presence of corresponding contact elements (such as blade strips or high-current pins) provided in the corresponding plug connector. In this case, when the operating element reaches the second position, it is tacitly assumed that the plug connector and the corresponding plug connector are in the final insertion position, thereby forming reliable electrical and mechanical contacts. That is, ultimately the CPA does not necessarily indicate a reliable electrical connection that is always operable. Such a locking function of the CPA often locks the operating element without ensuring that the plug-in device also covers the blade strip in the final position. Depending on the installation space, it is extremely difficult to detect such incorrect assembly visually or tactilely. Because the plug connector, the CPA, the operating element, and the corresponding plug connector appear (externally) to be in their normal positions relative to each other, and the operating element can no longer be moved relative to the plug connector.

[0007] Therefore, there may be a need to improve a plug connector assembly provided with an operating element for reducing insertion force and a CPA, such that the CPA reliably and dependably indicates the presence of the corresponding plug connector and indicates the proper achievement of the final insertion position between the plug connector and the corresponding plug connector.

[0008] Advantages of the Invention This need can be satisfied by the subject matter of the invention as recited in each of the independent claims. Advantageous embodiments of the invention are recited in each of the dependent claims.

[0009] According to a first aspect of the invention, a plug connector assembly is proposed.

[0010] This plug connector assembly has a plug connector with a plug connector housing, a corresponding plug connector with a corresponding plug connector housing, an operating element, and a CPA (Connector Position Assurance). The plug connector has an insertion position relative to the corresponding plug connector and can be mated with the corresponding plug connector along the insertion direction from an initial insertion position to a final insertion position. The operating element is movable between a first position and a second position and is formed to reduce the insertion force when the plug connector and the corresponding plug connector are connected. When the operating element moves from the first position to the second position, the plug connector is moved from the initial insertion position to the final insertion position. The CPA is movable along the movement direction between an unlocked position and a locked position. In this case, the CPA blocks the movement of the operating element from the second position to the first position in the locked position. In this case, it is defined that the CPA and the corresponding plug connector or the plug connector are adjusted relative to each other or formed relative to each other such that the movement of the CPA from the unlocked position to the locked position is blocked in relation to the insertion position.

[0011] For example, it may be defined that the movement of the CPA from the unlocked position to the locked position is blocked or released in relation to the insertion position. The release may additionally be related to the position of the operating element, for example.

[0012] This is advantageous as it can prevent misinsertion between the plug connector and the corresponding mating connector. Thus, for the operator, even if only the operating element is moved to its second position, it is impossible to move the CPA which is movable as a signal indicating a proper insertion from the unlocked position to the locked position. Therefore, the CPA is actually movable particularly in relation to the insertion position between the plug connector and the corresponding mating connector.

[0013] The "initial insertion position" can be interpreted as, for example, a state where the plug connector and the corresponding mating connector are not yet mated, or are at most loosely in contact with each other, or have not yet approached each other. In particular, the "initial insertion position" can also be interpreted as the state of the plug connector where it is not yet even attached to the corresponding mating connector or has not yet mechanically contacted the corresponding mating connector. For example, the plug connector can be provided in the initial insertion position (for example, in a state attached to a wire harness). Then, starting from this initial insertion position, the plug connector is attached to the corresponding mating connector (for example, a pin of a high-current connection provided in a control device, such as a blade strip or, for example, in an inverter or battery of an electric vehicle). Therefore, the initial insertion position can correspond to the pre-insertion state. For example, with the operation of the operating element and the start of mating by the movement in the approaching direction between the plug connector and the corresponding mating connector, the initial insertion position ends.

[0014] For example, it may be specified that the plug connector has (at least) one contact element.

[0015] For example, it may be specified that the corresponding mating connector has (at least) one corresponding contact element.

[0016] For example, it may be specified that the contact element is electrically connected to the corresponding contact element at the final insertion position. For example, it may be specified that the insertion connector is inseparably connected to the corresponding insertion connector at the final insertion position. This means that the insertion connector and the corresponding insertion connector do not dissociate from each other in any spatial orientation, particularly without an external action to be applied by an operator.

[0017] For example, it may be specified that the insertion connector and the corresponding insertion connector are connected to each other at the final insertion position, particularly mechanically and / or electrically connected to each other.

[0018] For example, it may be specified that at the initial insertion position, the insertion connector and the corresponding insertion connector are prevented from being lost and are not connected to each other, or that at the initial insertion position, the insertion connector and the corresponding insertion connector have not yet come into contact with each other.

[0019] For example, it may be specified that the operating element is arranged on the insertion connector, particularly arranged in the insertion connector housing. In an alternative configuration, for example, it may be specified that the operating element is arranged on the corresponding insertion connector, particularly arranged in the corresponding insertion connector housing.

[0020] For example, the operating element may be defined as being arranged particularly in a mating plug connector or cooperating with a structure arranged in the plug connector such that when the operating element moves from a first position to a second position, the plug connector is caused to move from an initial insertion position to a final insertion position. For example, when the operating element is arranged in the plug connector, the operating element may have a slide guide which cooperates with a structure formed as a pin provided in the mating plug connector, thus covering the plug connector over the mating plug connector and pulling it in from the initial insertion position to the final insertion position when the operating element moves from the first position to the second position. The structure may be formed, for example, as a slide guide, a gear, a rack or the like. Correspondingly, a corresponding structure complementary to the structure is formed on the operating element.

[0021] In the context of the present application, the term "comprising" may be construed as synonymous with the term "having", unless stated otherwise.

[0022] In one refinement, it is defined that before reaching the final insertion position, the movement of the CPA from the unlocking position to the locking position is blocked. This is advantageous as it clearly indicates to the operator, based on the impossibility of moving the CPA, that the plug connection between the plug connector and the mating plug connector has not yet been properly established. For example, even if only the operating element has been (substantially) moved to the second position, for example, if the plug connector is not fully placed on the mating plug connector, or if in such a case the plug connector is not covered over the mating plug connector, the blocking of the movement of the CPA simply and mechanically, tactilely and visually suggests to the operator that there is still a misinsertion or that the proper insertion has not been achieved.

[0023] For example, at the final insertion position, it may be specified that the movement of the CPA from the unlock position to the lock position is enabled. However, at the final insertion position, only the blocking element of the CPA (e.g., the locking arm) is released from its blocking, and it may be specified that the final movability of the CPA is related to the position or position of another element of the plug connector assembly, e.g., the operating element.

[0024] In one improved form, it is specified that the CPA is arranged on the operating element. This is advantageous because the CPA can be manufactured and assembled particularly simply and inexpensively. The CPA is provided together with the operating element. Furthermore, this is advantageous for the operator because the CPA is always directly visible during the operation of the operating element and can be operated in one working step. This shortens the cycle time when assembling the plug connector assembly by mating the plug connector with the corresponding plug connector.

[0025] Alternatively or additionally, it is specified that the CPA is arranged on the plug connector, e.g., in the plug connector housing. This is advantageous because the movability of the CPA can easily be made related to the position or position of another element of the plug connector assembly, e.g., the position of the operating element. Furthermore, it is advantageous because the CPA is thus particularly well protected against damage.

[0026] Alternatively or additionally, it is specified that the CPA is arranged on the corresponding plug connector, e.g., in the corresponding plug connector housing. This is advantageous because the movability of the CPA can easily be made related to the position or position of another element of the plug connector assembly, e.g., the position of the operating element. Furthermore, it is advantageous because the CPA is thus particularly well protected against damage.

[0027] In an improved form, it is specified that the operating element is formed as a slider and / or as a lever rotatable about a predetermined axis. This is advantageous because it provides an operating element that can be operated particularly well. In the case of a lever configuration, in particular, the insertion force for the operator can be adjusted and reduced particularly easily via the length of the lever.

[0028] In an improved form, the CPA has a locking element, the locking element being lockable to a corresponding element, where in this case the locking element is specified to be displaceable between a first position and a second position. The locking element is locked to the corresponding element in the first position, preventing the CPA from moving from the unlocking position to the locking position, and the locking element is not locked to the corresponding element in the second position. The locking element is located in the first position in the initial insertion position, where in this case a first unlocking element is arranged in the insertion connector housing or the corresponding insertion connector housing, and this unlocking element is formed such that in the final insertion position the locking element is moved to the second position by the first unlocking element.

[0029] In other words, the first unlocking element moves the locking element to the second position at the final insertion position.

[0030] For example, it may be specified that the CPA is movable from the unlocking position to the locking position in the second position of the locking element. However, for example, whether the CPA is movable to the locking position may be specified in relation to the position of at least one other element of the insertion connector assembly.

[0031] The locking element may be formed, for example, to be elastically reversibly movable between the first position and the second position. The locking element may be formed, for example, as a locking arm.

[0032] This is advantageous because it provides a particularly simple, inexpensive, and reliable mechanical blocking of the CPA. At the same time, this ensures that the CPA can only be unblocked when it mechanically contacts the unlocking element, which is not part of the operating element. In this way, proper insertion can be detected very reliably and surely.

[0033] In one refinement, it is specified that the first unlocking element is formed as a protrusion on the plug connector housing or the corresponding plug connector housing.

[0034] This protrusion may protrude outward from the plug connector housing or the corresponding plug connector housing, for example, in a radial direction perpendicular to the insertion direction.

[0035] This provides a particularly simple, inexpensive, and robust configuration for moving the locking element to the second position. Furthermore, the configuration as a protrusion ensures that the final insertion position cannot be achieved at all when the plug connector is inserted incorrectly (for example, in a 180° rotated state) or when using an inappropriate plug connector for the corresponding plug connector (for example, a similar plug connector that does not fit the existing corresponding plug connector). This is advantageous because the protrusion acts according to a kind of key locking principle. This improves the safety and reliability of the plug connector assembly, especially when using high currents.

[0036] In one refinement, the locking element has a locking element protrusion that protrudes radially inward, and in this case, the locking element protrusion contacts the first unlocking element in the final insertion position, whereby the locking element is defined to be moved to the second position by the first unlocking element.

[0037] The second position can be achieved, for example, by moving the locking element radially outward.

[0038] The second position can be achieved, for example, when the CPA is in the unlocked position.

[0039] Subsequently, when the CPA is moved from the unlocked position to the locked position, for example, the locking element protrusion is moved beyond the protrusion, and the locking element is moved away from the second position, for example, returned to the first position (e.g., by the elasticity of the locking element that allows elastically reversible movement from the second position to the first position). It may be defined that the locking element protrusion can then prevent the movement of the CPA from the locked position to the unlocked position, in which case the locking element protrusion is locked with, for example, the protrusion or another corresponding element, or is blocked in an undercut manner. In such a case, in order to release the plug connector assembly (i.e., pull the plug connector and the corresponding plug connector away from each other), it may be necessary to first move the locking element to the second position (e.g., by tilting the CPA or a release element or the like), and then release the locking element protrusion from the engaged state with the protrusion or another corresponding element.

[0040] In one improvement, the CPA and the operating element are formed to cooperate with each other such that the movability or movement of the CPA from the unlocked position to the locked position is related to the position of the operating element. In this case, it is defined that the CPA is not movable from the unlocked position to the locked position in the first position of the operating element.

[0041] For example, it may be defined that the CPA is movable from the unlocked position to the locked position only when the operating element is in the second position and the final insertion position is achieved.

[0042] This makes it advantageous as the locking of the operating element can be reliably and easily achieved by the CPA. Further, this prevents the CPA from becoming movable already when the plug connector is mounted on the corresponding plug connector without an operating element or using a damaged operating element, pressed to the final insertion position, and only the final insertion position has been achieved. This is also advantageous as it further ensures that the plug connector and the corresponding plug connector do not become disengaged from each other after the final insertion position has been reached. This is because the operating element may be formed to prevent loss of the plug connector and fix its position on the corresponding plug connector, for example, based on a self-locking effect.

[0043] However, in addition to the presence of the above two conditions, it may be specified that the movement of the CPA from the unlocking position to the locking position is related to the position of another element of the plug connector assembly.

[0044] In one improvement, the CPA has another locking element, the other locking element is lockable to another corresponding element, the other locking element is displaceable between a third position and a fourth position, the other locking element is locked to another corresponding element in the third position, preventing the CPA from moving from the unlocking position to the locking position, the other locking element is not locked to another corresponding element in the fourth position, in particular the CPA is movable from the unlocking position to the locking position, the other locking element is located in the third position at the first position of the operating element, and a second unlocking element is provided, in particular arranged on the operating element, and the second unlocking element is formed such that the other locking element is moved or has been moved to the fourth position by the second unlocking element at the second position of the operating element.

[0045] This is advantageous as it results in a particularly simple, inexpensive, and robust, especially purely mechanical configuration of the other locking element and the CPA.

[0046] Basically, it may be defined that a locking element and another locking element are formed as one common locking element. In this case, the descriptions as the "locking element" and the "another locking element" are only used to explain various functionalities (for example, blocking before reaching the final insertion position and blocking before reaching the second position). For example, in this case, the movement from the first position to the second position is performed in the first direction, and the movement from the third position to the fourth position may be performed in the second direction. Such a second direction may extend substantially perpendicular to the first direction, for example. However, it is also possible that the locking element and the another locking element are separate elements from each other. The locking element and the another locking element may be formed, for example, as two locking arms arranged at intervals from each other. The locking element and the another locking element may be formed, for example, to be elastically and reversibly movable.

[0047] In one improvement, it is defined that the second unlocking element is formed on the operating element as another protrusion.

[0048] Thereby, a particularly simple, inexpensive, and robust second unlocking element is provided.

[0049] This another protrusion may protrude from the operating element, for example, in a radial direction perpendicular to the insertion direction.

[0050] In one improvement, this another locking element has another additional locking element protrusion, and this another additional locking element protrusion is in contact with the second unlocking element at the second position of the operating element. Thereby, it is defined that this another locking element is moved to the fourth position by the second unlocking element.

[0051] Thereby, it is advantageous that a particularly simple, inexpensive, robust, and reliable, purely mechanical arrangement is provided to release the blocking of the CPA in relation to the position of the operating element.

[0052] Such movement to the fourth position can be effected, for example, in a direction of movement effected by the first unlocking element on the locking element at the final insertion position or in a direction orthogonal to the movement. In other words, the direction of movement from the third position to the fourth position may extend substantially (e.g., + / - 30°) perpendicular to the direction of movement from the first position to the second position.

[0053] According to another aspect of the invention, a plug connector for a plug connector assembly having a corresponding plug connector is proposed.

[0054] This plug connector has a plug connector housing, an operating element, and a CPA. This plug connector has an insertion position relative to the corresponding plug connector and can be mated with the corresponding plug connector along the insertion direction from the initial insertion position to the final insertion position. The operating element is movable between a first position and a second position and is formed to reduce the insertion force when connecting the plug connector and the corresponding plug connector. When the operating element moves from the first position to the second position, the plug connector is moved from the initial insertion position to the final insertion position. The CPA is movable between an unlocked position and a locked position along the direction of movement. The CPA blocks the movement of the operating element from the second position to the first position in the locked position. The CPA and the corresponding plug connector are adjusted relative to each other such that the movement of the CPA from the unlocked position to the locked position is blocked in relation to the insertion position.

[0055] This is advantageous because, for example, the movement of the CPA cannot be effected merely by moving the operating element to the second position. This is advantageous because the proper insertion can be better indicated by the CPA.

[0056] According to yet another aspect of the invention, a corresponding plug connector for a plug connector assembly having a plug connector with an operating element is proposed.

[0057] This mating plug connector has a mating plug connector housing and a CPA. The plug connector has a plugging position relative to the mating plug connector and can be mated with the mating plug connector along the plugging direction from the initial plugging position to the final plugging position. The CPA is movable between an unlocking position and a locking position along the moving direction. The CPA blocks the movement of the operating element from the second position to the first position in the locking position. The CPA and the mating plug connector are relatively adjusted to each other such that the movement of the CPA from the unlocking position to the locking position is blocked in relation to the plugging position.

[0058] Thus, for example, merely moving the operating element to the second position makes it impossible for the CPA to move, which is advantageous. Thus, the establishment of a proper plug-in can be better indicated by the CPA, which is advantageous.

[0061] Hereinafter, FIGS. 1a and 1b will be described together with reference to FIGS. 2, 3, 4, and 5c.

[0062] In FIGS. 1a and 1b, schematic perspective views showing the plug connector assembly 100 in different assembled states are shown.

[0063] The plug connector assembly 100 includes a plug connector 1 with a plug connector housing 2, a corresponding plug connector 3 with a corresponding plug connector housing 4, an operating element 5, and a CPA 20 (CPA = ”Connector Position Assurance”).

[0064] The plug connector 1 may be formed, for example, as a plug connector 1 for a high-current plug connector assembly (for example, for output transmission from a battery to an inverter and / or for an electric machine in an electric vehicle), but other plug connection parts, for example, high-polarity plug connection parts, are also conceivable. The plug connector 1 may be arranged, for example, in a cable harness or may be attached. In this case, for example, two cables 18 are arranged in the plug connector 1, and these cables 18 each have one (electrical) line 15 (FIG. 2) and an insulating part 16 surrounding this line 15.

[0065] The plug connector housing 2 may in this case have, for example, a tongue, which may be formed as a locking tongue 17 (see also FIG. 3). The locking tongue 17 is in this case elastically reversibly displaceable, for example, along a radial direction R perpendicular to the insertion direction S. The locking tongue 17 can in this case be displaced elastically by a spring force, for example, towards the inside in the radial direction. The corresponding plug connector 3 has a projection 41 on the corresponding plug connector housing 4. This projection 41 projects in a hook shape from the corresponding plug connector housing 4 towards the outside in the radial direction, and in this case, for example, has an opening 42 between the projection 41 and the corresponding plug connector housing 4 (see FIG. 4). The tongue or, in this case, the locking tongue 17 can be guided through the opening 42 when the plug connector 1 and the corresponding plug connector 3 are mated. The locking tongue 17 can be locked, for example, under the hook-shaped projection 41 in the final insertion position EP (see FIG. 3). Of course, embodiments without the locking tongue 17 and / or embodiments without the projection 41 are also conceivable.

[0066] The corresponding plug connector 3 may be formed, for example, as a blade strip or a pin assembly. The blade strip or pin assembly is arranged on a component, for example, a control device or an inverter or the like. In this case, the corresponding plug connector 3 is arranged, for example, in a component housing 70. The corresponding plug connector 3 is screwed or attached to the component housing 70, for example, using four screws, and partially protrudes into the inside of the component housing 70 through a notch provided in the component housing 70, whereas the plug connector 1 is, in this case, for example, completely located outside the component housing 70.

[0067] The plug connector 1 has a plugging position relative to the corresponding plug connector 3. The plug connector 1 can be mated with the corresponding plug connector 3 along the plugging direction S from the initial plugging position AP (Fig. 1a) to the final plugging position EP (Fig. 1b). The initial plugging position AP of the plug connector 1 is already, unlike the state shown in Fig. 1a, a state where the plug connector 1 is not yet mounted on the corresponding plug connector 3, or a state where the plug connector 1 is not yet connected to the corresponding plug connector 3, for example, a state where the plug connector 1 is supplied together with a cable harness.

[0068] The plug connector 1 may have, for example, at least one contact element 7, and in this embodiment, it may have two contact elements 7 (see Fig. 2). The corresponding plug connector 3 may have at least one corresponding contact element 8 (see Fig. 2), and in this embodiment, the corresponding plug connector 3 has two corresponding contact elements 8 (see Fig. 4). At the final plugging position as shown in Fig. 2, both contact elements 7 are electrically connected to both corresponding contact elements 8.

[0069] The plug connector 1 and the corresponding plug connector 3 are connected to each other at the final plugging position EP, particularly mechanically and electrically. The plug connector 1 and the corresponding plug connector 3 are connected to each other in a non-lostable manner at the final plugging position EP. Therefore, unless manual interference is performed to release the non-lostable connection, the plug connector 1 cannot be detached from the corresponding plug connector 3 under standard operating conditions at any spatial position. In contrast, at the initial plugging position AP, the plug connector 1 and the corresponding plug connector 3 may not be connected to each other in a loss-preventing manner. That is, the plug connector 1 and the corresponding plug connector 3 may only be in loose contact with each other.

[0070] The operating element 5 is movable between a first position P1 (Fig. 1a) and a second position P2 (Fig. 1b). The operating element 5 is formed to reduce the insertion force when connecting the plug connector 1 and the corresponding plug connector 3. In this case, when the operating element 5 moves from the first position P1 to the second position P2, the plug connector 1 is moved from the initial insertion position AP to the final insertion position EP - provided that the plug connector 1 is properly mounted on the corresponding plug connector 3. This can be said when the plug connector 1 is placed over or mounted on the corresponding plug connector 3 at its initial insertion position AP as shown in Fig. 1a.

[0071] In this exemplary embodiment, the operating element 5 is arranged on the plug connector 1, in this case for example on the plug connector housing 2.

[0072] The operating element 5 is in this case formed as a lever 6 rotatable about an axis X, for example. The lever 6 is rotatably supported on a pin 12, for example, which is arranged in the plug connector housing 2 in this case. Instead of the pin 12, a shaft may be provided.

[0073] The operating element 5 is formed to cooperate with a structure 9 arranged on the corresponding plug connector 3, for example. In this case, when the operating element 5 moves from the first position P1 to the second position P2, the plug connector 1 is moved from the initial insertion position AP to the final insertion position EP. In this exemplary embodiment, the operating element 5 has one slide guide 11 on each of two sides (two lever arms), and this slide guide 11 cooperates with a structure 9 formed as a pin 10 in this case.

[0074] The CPA 20 is movable between an unlocking position EL and a locking position SL along the (first) moving direction V. In this case, the CPA 20 blocks the movement of the operating element 5 from the second position P2 to the first position P1 at the locking position SL (see Fig. 5c for this). In this exemplary embodiment, the CPA 20 and the corresponding plug connector 3 are adjusted relative to each other. In this case, the movement of the CPA 20 from the unlocking position EL to the locking position SL is blocked in relation to the plugging position. This is explained in more detail, for example, further below in connection with Figs. 5a - 5c.

[0075] For example, in this case, it is specified that the movement of the CPA 20 from the unlocking position EL to the locking position SL is blocked before reaching the final plugging position EP (see Fig. 5a). For example, in this case, it is specified that the movement of the CPA 20 from the unlocking position EL to the locking position SL is made possible at the final plugging position EP (see Figs. 5b and 5c).

[0076] The CPA 20 is, for example, arranged on the operating element 5 in this case. The CPA 20 may alternatively or additionally be arranged on the plug connector housing 2 or the plug connector 1. The CPA 20 may alternatively or additionally be arranged on the corresponding plug connector 3, in particular on the corresponding plug connector housing 4.

[0077] Fig. 2 shows a schematic cross - sectional view of the plug connector assembly 100 at the final plugging position EP. In this case, the cutting line is drawn so as to pass through one contact element 7, the associated corresponding contact element 8, and the associated cable 18 having the line 15 and the insulation 16 (see Fig. 1b). Therefore, the CPA 20 is not visible in this drawing.

[0078] The plug connector 1 has a sealing element 13 in the plug connector housing 2. The sealing element 13 is formed in this case, for example, as a radial sealing member. The sealing element 13 is arranged at a first end of the plug connector housing 2 facing the corresponding plug connector 3. In the final insertion position EP, the sealing element 13 seals the inner chamber 80 of the plug connector assembly 100 against the ingress of dirt, mud, dust, moisture and other fluid media from the external environment 81 of the plug connector assembly 100. For this purpose, the sealing element 13 is in contact with the corresponding plug connector housing 4.

[0079] The plug connector 1 further has another sealing element 14. This another sealing element 14 is arranged at a second end on the cable side. This another sealing element 14 is also formed in this case, for example, as a radial sealing member and is in contact with the insulation 16 of the cable 18. Thus, this another sealing element 14 seals the inner chamber 80 against the ingress of dirt, mud, dust, moisture and other fluid media from the external environment 81 of the plug connector assembly 100. This another sealing element 14 may be arranged on the cable 18 before the cable 18 is assembled, and in that case, it can be introduced into the plug connector housing 2 when the cable 18 is assembled to the plug connector housing 2 or when the cable 18 is incorporated into the plug connector housing 2.

[0080] Figure 3 shows a schematic perspective view of the plug connector assembly 100 in the final insertion position shown in Figure 1b, with the operating element 5 removed for clarity of illustration (the operating element 5 is actually in the second position P2). As explained above, it can be clearly seen that the corresponding plug connector housing 4 is provided with a protrusion 41 having an opening 42. It can also be clearly seen that the locking tongue 17 is introduced through this opening 42 from above. The protrusion 41 can be used, for example, as an undercut for the locking tongue 17 having a locking projection protruding radially outward, for example, at the final insertion position EP. For example, by this alone, the plug connector 1 may be prevented from being lost at present and may be arranged or fixed in position to the corresponding plug connector 3 at the final insertion position EP in this embodiment.

[0081] Figure 4 shows a schematic perspective view of the corresponding plug connector 3 of the plug connector assembly 100 shown in Figure 3. The protrusion 41 arranged on the corresponding plug connector housing 4, as well as the opening 42 formed in the protrusion 41 in this case, for example, can be clearly seen. In this case, the protrusion 41 is formed in a hanger shape and is closed in a ring shape (together with a part of the corresponding plug connector housing 4).

[0082] Figures 5a to 5c show schematic cross-sectional views of a part of the plug connector assembly 100 shown in the previous drawings in various assembled states, and Figures 5a to 5c will be described together below. The drawings are not drawn to scale. In particular, the function of the CPA 20 is illustrated so that the function of the locking tongue 17 is not shown for better understanding. The locking tongue 17 is only depicted as a kind of tongue in this case, but this tongue also constitutes one possible embodiment.

[0083] As exemplarily illustrated in Figures 5a to 5c, the CPA 20 and, for example, the corresponding plug connector 3 in this case are adjusted relative to each other such that the movement of the CPA 20 from the unlocking position EL to the locking position SL is blocked in relation to the insertion position.

[0084] This is advantageous because it results in the fact that the CPA20 cannot be moved from the unlocking position EL to the locking position based solely on the position of the operating element 5. If such movement of the CPA20 were possible only in relation to the position of the operating element 5, then, before the mating of the plug connector 1 and the corresponding plug connector 3, the operating element 5 might be moved to a position (e.g., the second position P2) where the CPA20 can move, and there is a risk that the CPA20 would be moved from the unlocking position EL to the locking position SL. Subsequently, when the plug connector 1 is mated with the corresponding plug connector 3, the operator might mistakenly assume that the plug connector assembly 100 is properly formed, resulting in malfunction. Also, when the plug connector 1 is mated with the corresponding plug connector 3, if the operating element reaches the target position (e.g., the second position P2) without actually reaching the final insertion position EP, it is possible for the CPA20 to become movable. In this case, the fact that the CPA20 becomes movable also sends incorrect information to the operator that the plug connection is properly established (even though it actually is not yet). By preventing the CPA20 from moving in relation to the insertion position between the plug connector 1 and the corresponding plug connector 3, such possible intentional or unintentional incorrect operations can be prevented.

[0085] As exemplarily illustrated in FIGS. 5a to 5c, it may be defined that the movement of the CPA20 from the unlocking position EL to the locking position SL is blocked before reaching the final insertion position EP (see FIG. 5a). Further, in this case, for example, at the final insertion position EP, particularly when the operating element 5 is located substantially at the second position P2, it may be defined that the movement of the CPA20 from the unlocking position EL to the locking position SL becomes possible (see FIGS. 5b and 5c).

[0086] The CPA20 has, for example in this case, a locking element 21 which can be locked to a corresponding element 30. The corresponding element 30 is formed in the operating element 5 in this case and acts as an undercut in this case. The locking element 21 is displaceable (for example, elastically reversibly in this case) between a first position S1 (Figs. 5a and 5c) and a second position S2 (Fig. 5b). The locking element 21 is locked to the corresponding element 30 in the first position S1, and the CPA20 is prevented from moving from the unlocking position EL to the locking position SL (Fig. 5a). The locking element 21 is not locked to the corresponding element 30 in the second position S2. Thus, for example in this case, the CPA20 can be moved from the unlocking position EL to the locking position SL in the second position S2 of the locking element 21 (Figs. 5b and 5c).

[0087] The locking element 21 is located in the first position S1 in the initial insertion position AP. In this exemplary embodiment, a first unlocking element 40 is arranged in the corresponding insertion connector housing 4, and this unlocking element 40 is formed such that the locking element 21 is moved to the second position S2 by the first unlocking element 40 in the final insertion position EP.

[0088] The first unlocking element 40 is formed, for example in this case, by a protrusion 41 provided in the corresponding insertion connector housing 4. In this case, as described above, the protrusion 41 protrudes outward from the insertion connector housing 2 or the corresponding insertion connector housing 4 in a radial direction R perpendicular to the insertion direction S, for example in this case.

[0089] The locking element 21 has, for example, a locking element protrusion 22 in this case, and this locking element protrusion 22 protrudes radially inward (towards the corresponding plug connector housing 4) in this case. In this case, the locking element protrusion 22 is in contact with a first unlocking element 40 (a protrusion 41 in this case) at the final insertion position EP and is moved to a second position S2 by the first unlocking element 40, and in particular is moved radially outward. This movement to the second position S2 is carried out in particular when the CPA 20 is in the unlocked position EL.

[0090] The CPA 20 has, for example, a base body 24 in this case, and the locking element 21 protrudes from this base body 24. The locking element 21 is formed, for example, as a locking arm in this case. The locking arm is formed as a cantilever in this case, and in this case, one end of the locking arm is attached to the base body 24. The locking arm is formed, for example, to be elastically reversibly displaceable between a first position S1 and a second position S2 in this case. The CPA 20 further has a grip element 25. Furthermore, the CPA 20 has a locking element 23. This locking element 23 is also formed as a cantilever arm in this case and extends substantially parallel to the locking element 21.

[0091] The locking element 23 is guided through the opening 42 when the CPA 20 moves from the unlocked position EL to the locked position SL (Fig. 5c), and thus cooperates with the inside of the protrusion 41 to prevent the movement of the operating element 5 in the direction from the second position P2 to the first position P1.

[0092] Therefore, in this embodiment, the protrusion 41 has three functions. On the one hand, at the final insertion position EP, the protrusion 41 is formed to cooperate with the locking tongue 17 of the insertion coupler 1 to prevent loss of the insertion connector 1 and hold it to the corresponding insertion connector. At the same time, the protrusion 41 is used, by its radially outwardly protruding surface (i.e., its protruding portion), to move the locking element 21 from the first position S1 to the second position S2 in relation to the insertion position. Further, the protrusion 41 causes, by the cooperation of its inwardly protruding surface with the locking element 23 of the CPA 20, that the operating element 5 cannot be moved in the direction from the second position P2 to the first position P1 at the locking position SL of the CPA 20.

[0093] By means of the grip element 25, the locking element 21 can basically also be moved from the first position S1 to the second position S2. In this case, for example, since pressure is applied to the grip element in a direction opposite to the movement direction V, the grip element 25 is tilted together with the locking element 21. However, as can be seen from FIGS. 5a and 5b, when the CPA 20 is in the unlocked position EL, the grip element 25 is in contact with the corresponding surface of the operating element 5. Therefore, the grip element 25 cannot be tilted by pressure in a direction opposite to the movement direction V at the unlocked position EL of the CPA 20. As a result, at the unlocked position EL of the CPA 20, the locking element 21 also cannot be moved from the first position S1 to the second position S2 by the grip element 25. This becomes possible only after the CPA 20 has been moved to the locking position SL, and thus only when the grip element 25 no longer contacts the corresponding surface of the operating element 5.

[0094] If the CPA20 is moved to the locking position SL, the CPA20 may also be prevented from moving from the locking position SL to the unlocking position EL by the locking element 21 (see FIG. 5c). This is caused, for example, by the locking element projection 22 in this case. The locking element projection 22 engages from behind with another undercut after the locking element 21 has been elastically returned to the first position S1 in this case (in this case, on the back side of the corresponding element 30). Such a prevention can be released, for example, when the plug connector 1 is to be removed from the corresponding plug connector 3 again, for example, by a manual operation of the operator (for example, at the grip element 25 of the CPA20 as described above). For this purpose, the locking element 21 is then manually moved to the second position S2, and subsequently the CPA20 is moved from the locking position SL to the unlocking position EL. Subsequently, the operating element 5 can be moved from the second position P2 to the first position P1. In this way, the plug connector 1 can be disengaged from the corresponding plug connector 3.

[0095] FIG. 5a shows the state when the plug connector 1 and the corresponding plug connector 3 are plugged together. In this state, the final insertion position EP is almost achieved, but not yet fully achieved. The operating element 5 is located approximately at the second position P2, but not yet fully at the second position P2. The CPA20 is located at the unlocking position EL. Furthermore, it can be seen that the locking tongue 17 is guided through the opening 42 of the projection 41.

[0096] Figure 5b shows a state where the final insertion position EP is reached and the protrusion 41 has moved the locking element 21 as the first unlocking element 40 to the second position S2 by the locking element protrusion 22, thus releasing the locking element 21 from engagement with the corresponding element 30. Thereby, the CPA 20 is no longer blocked from moving from the unlock position EL to the lock position SL. The movement of the locking element 21 to the second position S2 may be completely independent of the accurate arrival of the operating element 5 at the second position P2. This can be done, for example, by appropriately setting the length of the first unlocking element 40. However, for example, the CPA 20 may also be arranged in the insertion connector housing 2 instead of the operating element 5.

[0097] Figure 5c shows a state where the CPA 20 has been moved to the lock position SL along the movement direction V (in this case, downward) after reaching the final insertion position EP. The locking element 21 has been returned to the first position S1 again, the locking element protrusion 22 is locked with the corresponding element 30 on the other side of the corresponding element 30, and moreover, it is locked to prevent the movement of the CPA 20 from the lock position SL to the unlock position EL. The grip element 25 can be used, for example, to move the locking element 21 to the second position S2 again, thereby releasing the blocking of the CPA 20 against movement from the lock position SL to the unlock position EL.

[0098] The locking element 23 may have a ramp. Thereby, for example, when the operating element 5 has not yet fully reached the second position P2 based on a manufacturing error or an error due to heat at the time of reaching the final insertion position EP, the locking element 23 will cooperate with the inside of the protrusion 41 to draw the operating element 5 to the second position P2 when the CPA 20 moves from the unlock position EL to the lock position SL.

[0099] Figures 6 and 7 show a schematic perspective view (Figure 6) of another plug connector assembly 100 shown in partial cross-section and a schematic perspective view (Figure 7) of the CPA 20 of this plug connector assembly 100. Figures 6 and 7 will be described together below.

[0100] In the plug connector assembly 100 shown in Figures 6 and 7, the CPA 20 is arranged in the plug connector housing 2.

[0101] In this case, the CPA 20 and the operating element 5 are formed to cooperate with each other such that the movement of the CPA 20 from the unlocking position EL to the locking position SL is related to the position of the operating element 5 (additionally with respect to the relationship with the insertion position). In this case, in the first position P1 of the operating element 5, the CPA 20 cannot move from the unlocking position EL to the locking position SL. For example, in this case, if the operating element 5 is in the second position P2 and at the same time the final insertion position EP exists, it is stipulated that the CPA 20 can move from the unlocking position EL to the locking position SL.

[0102] Thereby, by using only a single purely mechanical element, in this case the CPA 20, on the one hand, the final insertion position EP can be achieved and, on the other hand, it can be ensured and indicated that the operating element 5 is in the second position P2. This enables a particularly simple and reliable inspection of the proper assembly of the plug connector 1 and the corresponding plug connector 3 and the proper formation of the plug connection between the plug connector 1 and the corresponding plug connector 3.

[0103] The CPA20 has another locking element 50 (in this case, two other locking elements 50, see Fig. 7). This other locking element 50 can be locked to another corresponding element 31 (in this case, two other corresponding elements 31, see Fig. 7). The other locking element 50 is displaceable between a third position S3 and a fourth position S4. In this case, these other locking elements 50 are locked to the corresponding other corresponding elements 31 respectively at the third position S3, and the CPA20 is blocked against movement from the unlocking position EL to the locking position SL. In this case, for blocking, it is sufficient if only one other locking element 50 is located at the third position S3. These other locking elements 50 are not locked to the corresponding other corresponding elements 31 at the fourth position S4 respectively.

[0104] When all the other locking elements 50 are located at the fourth position, the CPA20 may basically be movable from the unlocking position EL to the locking position SL, or is no longer blocked. These other locking elements 50 are located at the third position S3 at the first position P1 of the operating element 5. A second unlocking element 60 is provided (in this case, two second unlocking elements 60), and the second unlocking element 60 is arranged on the operating element 5 in this case (in this case, both second unlocking elements 60 are arranged on the operating element 5). Both second unlocking elements 60 are formed such that at the second position P2 of the operating element 5, the other locking element 50 is moved to the fourth position S4 by the second unlocking element 60.

[0105] In this embodiment, it is specified that each of the other locking elements 50 has one other locking element protrusion 51. These other locking element protrusions 51 protrude from the other locking element 50 in the radially lateral direction, for example, in a direction away from each other and outward. These other locking element protrusions 51 are locked to, for example, one of the other corresponding elements 31 respectively at the third position S3 of the other locking element 50.

[0106] Furthermore, for example, in this case, each of the two separate locking elements 50 is provided with one respective additional locking element protrusion 52. These respective additional locking element protrusions 52 are spaced apart from the other locking element protrusion 51 when viewed along the insertion direction S.

[0107] These respective additional locking element protrusions 52 each protrude laterally in the radial direction from the other locking element 50 in this case, and in this case, the respective additional locking element protrusions 52 of the two separate locking elements 50 are directed away from each other in this case. The two respective additional locking element protrusions 52 each have, for example, one respective ramp, and when the operating element 5 has reached approximately the second position P2, the second unlocking element 60 rides up along this ramp. Then, when the operating element 5 is completely moved to the second position P2, the two respective additional locking element protrusions 52 are pushed laterally inwards (in the direction of approaching each other) in this case, and as a result, the two separate locking elements 50 are moved from the third position S3 to the fourth position S4. Basically, another configuration for causing the movement of the other locking element 50 from the third position S3 to the fourth position S4 is also possible.

[0108] In other words, the other locking element 50 has a respective additional locking element protrusion 52, and in this case, this respective additional locking element protrusion 52 is in contact with the second unlocking element 60 in the second position P2 of the operating element 5, whereby the other locking element 50 is (indirectly in this case) moved to the fourth position S4 by the second unlocking element 60. This movement is performed, for example, in a direction orthogonal to the movement caused by the first unlocking element 40 on the locking element 21 at the final insertion position EP in this case. However, for example, another movement direction in the direction of the insertion connector housing 2 is also possible.

[0109] In FIG. 7, to show the action of the third position S3 and the fourth position S4, another locking element 50 drawn on the right side is illustrated in the third position S3 (locked position), and another locking element 50 drawn on the left side is illustrated in the fourth position S4 (no longer locked position). In the second position P2 of the operating element 5 without defects, it is desirable that both of the other locking elements 50 are located in the fourth position S4.

[0110] In this case, for example, the second unlocking element 60 is formed on the operating element 5 as another protrusion 61 respectively. This another protrusion 61 protrudes from the operating element 5 in the radial direction R perpendicular to the insertion direction S in particular (in this case, it is directed towards the corresponding insertion connector housing 4 in the second position P2).

[0111] In this embodiment, the first unlocking element 40 is formed by the wall section 43 of the corresponding insertion connector housing 4. The locking element 21 of the CPA 20 rides on the end face 44 of this wall section 43 by means of an additional locking element protrusion 26 having a ramp in this case at the final insertion position EP during the mating of the insertion connector 1 and the corresponding insertion connector 3. Thereby, the locking element 21 is moved from the first position S1 to the second position S2 (see FIG. 6). Thereby, the locking element protrusion 22 is released from engagement with the corresponding element 30 provided in the insertion connector housing 2 (see FIG. 6). Thus, at the final insertion position EP, the blocking of the CPA 20 by the locking element 21 that prevents movement from the locked position SL to the unlocked position EL is released.

[0112] Therefore, if both the final insertion position EP and the second position P2 are achieved, the locking element 21 of the CPA 20 as well as the two separate locking elements 50 may be released from locking with the corresponding element 30 or the two separate corresponding elements 31, enabling the CPA 20 to move from the unlocking position EL to the locking position SL. This mobility serves as a reliable signal for the operator, indicating that the insertion connector 1 and the corresponding insertion connector 3 are properly mated. Further, the CPA 20 moved to the locking position SL serves as a mark indicating that the insertion connection is properly established, for example, in the case of visual quality control.
