Description

Technical Field

[0001] The present invention relates to a plug connector for mating with a mating connector, and a connector kit. Background Technology

[0002] Plug connectors and connector kits are known from the prior art, and different requirements are imposed on them. For example, these plug connectors (and the same applies to connector kits not always explicitly mentioned below) tend to receive an increasing number of plug contacts, thus increasing the force required to mate the plug connector and mating connector together. At the same time, there is an effort to reduce the size of the plug connector.

[0003] To overcome insertion force, existing plug connectors and connector kits may include levers. Thus, the user can apply the force required to insert them together using levers. However, levers increase the size of the plug connector.

[0004] Therefore, the object of the present invention is to provide a plug connector or connector kit to meet the requirements for insertion force and maximum size. Summary of the Invention

[0005] The present invention achieves this objective for the plug connector mentioned at the beginning, wherein the plug connector includes a connector housing and a lever device having a lever movable from an insertion position to a fixed position, and a connecting member movable by the lever and capable of engaging with a mating connector, wherein a lever extension is attached to the lever, the lever extension being extendable and / or retractable relative to the lever, wherein, in the fixed position of the lever, rotational movement of the lever from the fixed position is prevented by the retracted lever extension, and wherein the connector housing includes a guide member by which insertion of the lever extension is prevented if the lever is moved out of the insertion position and is not in the fixed position.

[0006] The present invention further achieves this objective for the connector kit mentioned at the beginning, wherein it includes a plug connector according to the invention and a mating connector having a connecting element that can engage with the connecting part of the plug connector.

[0007] The plug connector and connector kit according to the invention have the advantage that the force exerted by the user to insert them together can be reduced by the lever extension, wherein the plug connector or connector kit does not increase the structural size of the plug connector in the retracted state. Therefore, the plug connector and connector kit according to the invention have enhanced operability and reduced size.

[0008] The plug connector and connector kit can be further improved through the embodiments described in more detail below. Additional technical features of these embodiments can be combined arbitrarily, or a technical feature can be omitted if the technical effect it provides is irrelevant.

[0009] The connecting element of a plug connector may be formed by a gear or individual teeth of such a gear. Similarly, the connecting element may be formed by a single tooth, beam, or the like extending away from the axis of rotation.

[0010] If the lever is neither in the insertion position nor in the fixed position, the guide member acts as a stop for the lever extension to prevent the lever extension from retracting.

[0011] If the lever is in a fixed position and the lever extension is retracted, the lever extension can directly or indirectly prevent the lever from rotating away from that fixed position. The lever extension can, in particular, be part of a lever mechanism.

[0012] In another advantageous embodiment of the plug connector according to the invention, the guide member can be designed as a constraint guide by which the lever extension moves relative to the lever during rotational movement. Thus, the position of the lever extension relative to the lever (i.e., whether and to what extent it retracts or extends) cannot be freely adjusted by the user, but is predetermined by the guide member. Therefore, operational errors originating from the lever extension are virtually eliminated.

[0013] The plug connector according to the invention can be further improved by a guide member comprising at least one connecting portion at the connector housing in which the lever extension is guided. Specifically, the connector housing may include two symmetrically arranged connecting portions. These connecting portions are preferably arranged opposite to each other at the connector housing, and each is receptacle in a direction parallel to the axis of rotation of the lever mechanism. The cross-section of the connecting portion may be semi-circular or rectangular, and the connecting portion is preferably designed to complement a guide member (e.g., a guide pin), which may be disposed in the lever extension and guided within the connecting portion.

[0014] The guide member can also be a sliding path or sliding surface formed on the outside of the connector housing.

[0015] In another advantageous embodiment, a receiving portion may be provided at the connector housing, in which the lever extension is received in its retracted state. This receiving portion may be a radial receiving portion. The receiving portion is understood as a recess in the connector housing. In a radial receiving portion, the recess extends in the radial direction, preferably away from the axis of rotation. The receiving portion is preferably rectangular or cuboid. Preferably, two symmetrical receiving portions are provided at the connector housing. The receiving portions may be arranged symmetrically to themselves and symmetrically relative to each other. The receiving portions may extend conically away from the axis of rotation of the lever mechanism, or taper towards the axis of rotation.

[0016] The guide member may terminate in the receiving portion. The guide member may be interrupted, and the receiving portion may follow the interrupted portion. In other words, the guide member may pass through the receiving portion. In the case of the connecting portion, the receiving portion may therefore be formed by an extension of the connecting portion, wherein the extension may extend substantially perpendicular to the original direction of the connecting portion. The connecting portion may also terminate in the receiving portion.

[0017] In a fixed position, the lever extension can be inserted into the receiving portion. Preferably, insertion is achieved by moving in, and particularly blocking, the lever.

[0018] When the lever extension is retracted or moved into the receiving portion (preferably multiple receiving portions), the rotational movement of the lever device can be prevented by forced engagement. Therefore, it is advantageous that the lever extension is formed at least partially complementary to the receiving portion. The lever extension is pushed into the receiving portion in a direction perpendicular to the rotational movement. Thus, the wall of the receiving portion extending radially can serve as a limiting stop for portions of the lever extension. These portions of the lever extension can also be referred to as the arms or legs of the lever extension. Preferably, the arms or legs of the lever extension are received in one or more receiving portions with a slight gap.

[0019] Both the lever and the lever extension preferably have an approximately U-shaped design. The lever can be rotatably held at the connector housing at its free end. The lever extension also preferably has a U-shaped design, but it is rotatably held at the lever. The lever and lever extension can embody a lever mechanism in which other components can be housed.

[0020] Specifically, the lever extension may have two legs and the connector housing may have two opposing receptacles, wherein the legs of the lever extension can be inserted into the receptacles in a fixed position.

[0021] According to the invention, it is particularly advantageous if the retracted lever extension does not protrude from the lever. Therefore, in the extended state, the lever extension allows for a greater insertion force with the same operating force (i.e., the force exerted by the user) than without the lever extension, thanks to the longer mechanical lever. Simultaneously, the structural dimensions of the plug connector can be reduced by retracting the lever extension. Preferably, the lever extension can be entirely contained within the volume of the lever. Accordingly, the lever can have a mounting portion for the lever extension, which can be accessed through a mounting opening and substantially completely surrounds the lever extension.

[0022] In another advantageous embodiment, the travel of the lever extension relative to the lever extension can depend on the angular position of the lever device. With this clear correlation between the angular position of the lever device and the travel of the lever extension, a variable insertion force adapted to the geometry and type of the plug connector can be generated, depending on the angular position of the lever device, under a constant force transmitted by the user to the lever device.

[0023] In the plug connector according to the invention, the lever extension can have a maximum stroke caused by the change in the length of the lever device between the retracted and extended states of the lever extension. When the lever extension is extended to its maximum stroke, the maximum insertion force can be achieved.

[0024] Therefore, in one embodiment of the plug connector according to the invention, it is advantageous to increase the travel of the lever extension relative to the lever extension when the lever device moves from the insertion position to the fixed position. The constraint guidance of the lever extension by the guide member designed in this way has the advantage that the required length of the lever device can be individually adapted to the plug connector used.

[0025] Therefore, as an example only, the required insertion force is less in the first stage when the plug connector is inserted into the mating connector than in the second stage. In the first stage, the connector housing is inserted into the mating connector housing, requiring less force than in the second stage when multiple electrical contacts are inserted together. To allow the user to meet the increased required force with a constant force, the lever extension is extended via a constraint guide, thereby extending the mechanical lever and allowing for a greater insertion force.

[0026] The increase in stroke can be linear or non-linear, depending on the rotation angle of the lever mechanism. Similarly, a two-stage increase in the length of the mechanical lever (achieved by extending the lever extension) is possible, for example, in cases where the corresponding mating contact elements are engaged before the first set of contact elements are engaged with the second set of contact elements.

[0027] Preferably, the lever extension can be held at the lever for linear movement toward the axis of rotation. In a particularly preferred manner, the lever extension can be moved from a fixed position on the lever assembly. This has the advantage that, during the orderly rotational movement of the lever, no component of the force performing the rotational movement causes the lever extension to move toward or away from the axis of rotation relative to the lever. Therefore, the rotational movement of the lever assembly is completely independent of the linear movement of the lever extension during its contraction or extension.

[0028] In another embodiment, the lever extension may have an anti-loss device that can restrictively hold the lever extension at the lever. This prevents accidental loss of the lever extension. The anti-loss device may be releasable so that the lever extension can be removed from the lever. Furthermore, the anti-loss device may include several latching stages to latch the lever extension, for example, in a retracted state. This has the advantage that the lever extension is secured in its retracted state and cannot be released on its own, i.e., without the application of force by the user.

[0029] The lever extension can provide a lever constraint for a relevant position (e.g., a retracted state and an extended state), which constrains movement between the lever and the lever extension, wherein a predetermined force is sufficient to release the lever constraint. Conversely, the anti-loss device can be a lever latch edge that stops against the other edge of the lever, wherein the latch is preferably released only upon actuation of a release element.

[0030] In another advantageous embodiment, the connector housing may include a constraint or latching element to constrain or prevent rotational movement of the lever away from the fixed position.

[0031] This has the following advantage: once the lever reaches the fixed position, it is temporarily fixed in that position even if the lever extension is not yet in its retracted state. Therefore, the constraint or latching element of the connector housing fixes the lever assembly in the fixed position and can be understood as the primary retainer, while the retracted lever extension can be understood as the secondary retainer.

[0032] In the above embodiments, the lever and / or lever extension preferably have a U-shape. However, other shapes for these two elements are conceivable. For example, the lever can be W-shaped, or more generally, comb-shaped, wherein such a lever can be secured to the axis of rotation by each of its teeth. The lever extension can also have a corresponding shape. Accordingly, the plug connector can also have more than one connection according to the invention, wherein a maximum of two connection portions can be provided on the side, and other connection portions can be formed in the connector housing.

[0033] The connector kit according to the invention may include any embodiment of the plug connector described above. The lever extension of the plug connector is preferably a housing retainer that can only be transferred to its retracted state when the plug connector and mating connector are properly inserted and connected. Such a lever extension can therefore represent CPA (Contact Position Guarantee).

[0051] The connector kit 1 with a plug connector 3 from the prior art is described below. Figures 3 to 11 The connector kit 1 or plug connector 3 according to the invention may also include basic elements of the connector kit 1 or plug connector 3 from the prior art. Therefore, numerous repetitive descriptions of technical features are omitted in the drawings. If technical features in different figures differ functionally from each other, they are explicitly described.

[0052] exist Figure 1 The prior art connector kit 1 is shown, which includes a plug connector 3 and a mating connector 5.

[0053] At the plug connector 3, the lever 7 is held at the connector housing 11 of the plug connector 3 to rotate about the rotation axis 9. The lever 7 has a U-shaped design and includes two lever arms 7a, which are partially clamped around the connector housing 11.

[0054] In the illustrated embodiment, lever 7 is integrally formed and may also be referred to as lever device 13.

[0055] At lever 7, a connecting member 15 is further provided near the axis of rotation 9. This connecting member can engage with a corresponding element of mating connector 5, thereby allowing plug connector 3 to be easily plugged into mating connector 5.

[0056] To allow the required insertion force F to act from the plug connector 3 through the coupling member 15 to the mating connector 5, the lever 7 has a lever length L. The lever length L is measured from one end 17 of the lever 7 to the axis of rotation 9. The lever length L corresponds to the length of the lever arm, as it is used in calculations based on the lever principle.

[0057] When comparing Figure 1 and Figure 2 As can be seen, when lever 7 is actuated by rotational movement 27 from insertion position 23 to fixed position 25 (this is symbolically represented), plug connector 3 and mating connector 5 insert into each other because during rotational movement 27, coupling element 15 is clamped behind the mating connector 5 (not shown), and plug connector 3 and mating connector 5 move toward each other. During this process, the rotation axis 9 of plug connector 3 moves toward mating connector 5, where the exact path followed by the rotation axis is irrelevant.

[0058] However, the lever length L required by the existing plug connector 3 leads to many disadvantages.

[0059] For example, lever 7 will collide with them in the area of ​​the feeder cable 19 and repeat the operation.

[0060] Furthermore, the required lever length L results in a protrusion 21a extending beyond the connector housing 11, which increases the required mounting volume of the connector kit 1 shown.

[0061] The following figures illustrate a plug connector 3 according to the invention, which, for example, can also be used with... Figure 1 and Figure 2 The mating connectors 5 shown are inserted together (see...) Figure 13 and 14 ).

[0062] Compared with the previously shown embodiments of the prior art, the basic components, such as connector housing 11, lever arm 7a, rotation axis 9 and coupling 15, remain unchanged.

[0063] However, the plug connector 3 according to the invention includes a lever device 13, which includes a lever 7 and a lever extension 29 attached to the lever 7, the lever extension 29 being extendable and / or retractable relative to the lever 7. The lever extension 29 may also be U-shaped.

[0064] Lever extension 29 Figure 4 Shown separately. The lever extension 29 includes two arms 31 and a base 33. The base 33 also includes a latching region 35.

[0065] Figure 4The embodiment of the lever extension 29 shown includes a guide pin 39 on the inner side 37 of the arm 31. A latching element 43 is provided on the outer side 41 of the arm 31. By way of example only, they have a semi-circular cross-section. Other cross-sections of the latching element 43 are also conceivable, such as pyramidal or serrated (neither shown).

[0066] However, Figure 3 The lever extension 29 received in the lever 7 of the plug connector 3 corresponds to Figure 4 The lever extension 29 in the first embodiment lacks a guide pin 39. For distinction, this lever extension in the first embodiment is designated by reference numeral 29a. Figure 4 The lever extension 29 corresponds to the lever extension in the second embodiment, which is indicated by reference numeral 29b.

[0067] The latching element 43 represents an anti-loss device 47 connected to the opening 45 in the lever arm 7a, through which the lever extension 29 is held in a restricted manner at the lever 7. The lever extension 29 is held linearly and movably at the lever 7, radially toward the axis of rotation 9 of the lever assembly 13.

[0068] The connector housing 11 includes two guide members 49 implemented as sliding surfaces 51. These guide members 49 are responsible for preventing the lever extension 29 from moving into the lever 7 when the lever 7 is removed from the insertion position 23 and is no longer in the fixed position 25. This is achieved by... Figure 4 This is accomplished by the two support surfaces 52 indicated in the diagram.

[0069] The guide member 49 is interrupted in the upper region 53 of the connector housing 11. A receiving portion 57 follows the interruption 55. The receiving portion can be understood as a recess in the connector housing. The guide member 49 terminates in the receiving portion 57 at or via the interruption 55. The receiving portion 57 may in particular be a radial receiving portion 58.

[0070] exist Figure 3 In the middle, the lever extension 29 is in the extended state 59 and protrudes beyond the lever 7.

[0071] In the following description Figures 5 to 7 The plug connector 3 according to the invention is shown in a side view, wherein the lever device 29 is cut open in the side wall region of the connector housing 11. The connector housing 11 is not cut open, but the lever 7 and the lever extension 29 are cut open. For better illustration, the axis of rotation 9 is not shown in all figures.

[0072] exist Figure 5As can be seen, the lever extension 29 rests on the guide member 49, preventing the lever extension 29 from retracting into the lever 7. This movement is blocked by the guide member 49 (i.e., the sliding surface 51). Furthermore, as can be seen in this representation, in the area of ​​the interruption 55, the guide member 49 terminates in the receiving portion 57.

[0073] If the lever device 13 moves with the rotational motion 27, the lever extension 29 will no longer be in contact with the guide member 49 in the area of ​​the interruption 55, such as Figure 6 As shown. By retracting the lever extension 29 towards the rotation axis 9, the following is achieved: Figure 7 The lever extension 29 shown is in its retracted state 61.

[0074] exist Figure 8 The retracted state 61 of the lever extension 29 is also shown in the perspective view of the plug connector 3 according to the invention. In the latter, the lever 7 is drawn semi-transparently for illustrative purposes. Figure 7 and Figure 8 In the middle, the lever is in its fixed position at 25 degrees.

[0075] Through the retracted lever extension 29, that is, because the lever extension 29 is in its retracted state 61, the lever 7 moves from the fixed position 25 to the insertion position 23 (see...). Figure 1 and Figure 9 The rotational movement 63 of the lever 7 is prevented by the forced engagement 65 between the receiving portion 57 and the lever extension 29 in the retracted state. In the retracted state 61, the lever extension 29 does not protrude beyond the lever 7 and is completely within the volume 67 of the lever.

[0076] Furthermore, it can be seen that the latching element 43 of the arm 31 of the lever extension 29 is received in the opening 45 of the lever 7 (in Figure 8 (Only one of them can be seen in the image), which represents the anti-loss device 47. The connector housing 11 also includes a restraint or latching element 69. The latter blocks the lever 7 at the latch tongue 71, which also... Figure 3 As shown in the diagram, the forced engagement 65 between the latch tongue 71 and the constraint or latching element 69 prevents rotational movement 63.

[0077] Therefore, the rotational movement 63 of lever 7 in fixed position 25 is prevented on the one hand by the constraint or latching element 69 and the corresponding latch tongue 71, and on the other hand by the retracted lever extension 29.

[0078] Rotational motion of lever 7 27 (see Figure 5 It is blocked by the connector housing 11 or by the forced engagement 65 of the retracted lever extension 29 and the receiving portion 57.

[0079] exist Figures 9 to 13The image shows another embodiment of the plug connector 3 according to the present invention. In this embodiment, the guide member 49 includes a connecting portion 73. In this connecting portion, the guide pin 39 (see...) Figure 4 The connector housing 11 is guided. Preferably, two guide pins 39 are provided, one on each side of the connector housing 11.

[0080] exist Figure 9 In the middle, the lever extension 29 is received in the lever 7 in its retracted state 61, with the lever in the insertion position 23. This provides a space advantage, which will be discussed later regarding... Figure 13 The connection 73 represents the constraint guide 75. Through this constraint guide 75, the extension stroke 77 of the lever extension 29 relative to the lever 7 depends on the angular position 79 of the lever device 13.

[0081] The angular position 79 of the lever device 13 can be inserted at position 23. Figure 9 ) and fixed position 25 ( Figure 11 and 12 The variation between ) is shown in Figure 81, which is not drawn to scale. The schematic dependence of the diagonal position 79 of stroke 77 is illustrated in Figure 81. Figure 9 In the middle. Starting from the insertion position 23, the stroke 77 increases to its maximum value (marked by "max") and remains at that maximum value until the fixed position 25 is reached. Since the lever extension 29 can retract into the receiving portion 57 in the fixed position 25, the stroke 77 is 0 (as shown in the image). Figure 9 (As shown) and the maximum stroke 77 are both possible. The latter marks the extended state 59 of the lever extension 29.

[0082] Therefore, during the rotational movement 27 of the lever 7 from the insertion position 23 to the fixed position 25, the lever extension 29 extends.

[0083] like Figure 10 As shown, this is already the case in the position between the insertion position 23 and the fixed position 25, wherein further rotational movement 27 is achieved when the lever extension 29 is in its extended state 59.

[0084] Finally, lever device 13 or lever 7 respectively reaches fixed position 25, wherein lever extension 29 remains in its extended state 59. This is in Figure 11 As shown in the diagram. However, in this position, the guide pin 39 is no longer blocked by the connecting portion 73, because the connecting portion 73 is interrupted at the receiving portion 57.

[0085] like Figure 12As shown, the interruption portion 55 (where the receiving portion 57 is adjacent to the connecting portion 73) allows the lever extension 29 to be transferred to the retracted state 61, wherein at least some portions of the lever extension 29 are received in the receiving portion 57. This is also the case in the second embodiment of the plug connector 3 according to the invention; therefore, in the retracted state 61 of the lever extension 29, a forced engagement 65 is formed between the receiving portion 57 and the lever extension 29, which prevents rotational movement 63.

[0086] It should be pointed out that, Figures 10 to 12 The embodiment of the connecting part 73 shown is similar to Figure 9 The connecting part 73 is different. Figure 10 middle, Figure 9 The connecting part 73 is schematically shown in dashed lines and indicated by the reference numeral 73a.

[0087] exist Figure 13 and 14 Two exemplary embodiments of the plug connector 3 according to the invention are shown in the corresponding connector kit 1 according to the invention. These figures are for illustrative purposes relative to... Figure 1 and Figure 2 The advantages of the existing technology solution are shown. Figure 13 The insertion position 23 of the lever 7, at the end 17 of the lever device 13, means that the connector kit 1 according to the invention does not contact the power supply cable 19, which increases operability.

[0088] Figure 14 Another advantage of the connector kit 1 according to the invention is shown, wherein the lever 7 is in its fixed position 25 and the lever extension 29 (hidden by the lever 7) is in its retracted state 61. The protrusion 21b, which can be implemented with the solution according to the invention, is significantly smaller than that of solutions from the prior art. Figure 2 The protrusion 21a of the ) therefore requires less installation space.
