Description

[Technical field]

[0001] The present invention relates to an assembly for a connector. [Background technology]

[0002] The connector may include various components, such as a housing portion, a cover attachable to the housing portion, and / or a lever for securing and / or moving the connector to a mating connector.

[0003] A problem associated with conventional connectors is that care must be taken when installing their components to avoid incorrect and potentially dangerous assembly. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention can be seen to be to provide a solution which makes manufacturing and assembly easier and less error-prone. [Means for solving the problem]

[0005] This is achieved by an assembly for a connector comprising a housing part, a cover configured to be attached to the housing part, a lever configured to be attached to the housing part and rotatable relative to the housing part from a start position to a final position when attached, and a lever lock that prevents rotation of the lever out of the final position when the lever lock is in the locked position and allows rotation of the lever when the lever lock is in the released position, the lever lock being movable from the released position to the locked position only when the lever is in the final position and the cover is attached to the housing part.

[0006] The lever lock can only be moved from the released to the locked position when both conditions are met, i.e. when the lever is in its final position and the cover is attached to the housing part, making manufacturing easier as there is no need to manually check for correct attachment.

[0007] The solution according to the invention can be further improved by the following further developments and advantageous embodiments which are independent of one another and can be combined in any way as required.

[0008] In a simple and reliable solution, the movement of the lever lock out of the released position and / or into the locked position may be prevented by a pair of engaging translation blocking members on the lever and the lever lock, respectively. In particular, the translation blocking members are engaged when the lever is not in its final position and / or the cover is not attached to the housing part. In the desired correctly assembled state, i.e. when the lever is in its final position and the cover is attached to the housing part, the engaging or blocking effect may be released or deactivated. The pair of translation blocking members are then disengaged at least for the movement of the lever lock from the released position to the locked position.

[0009] Movement from the locked position back to the released position may be blocked or free in the correctly assembled state. For example, it may be necessary to unblock a further mechanism to leave the locked position. The further mechanism may be an automatically engaging mechanism, for example a latch mechanism that forms a form fit when the lever lock is moved from the released position to the locked position. This can prevent unintentional release of the connector, thus providing further safety.

[0010] In an advantageous embodiment, the cover may comprise a release element for disengaging the two translation blocking members when the lever is in the final position and the cover is attached to the housing part. The release element may be a part or part of the cover. It may be integral or integral with other parts of the cover. The cover may be a single piece, preferably made from a uniform material.

[0011] The release element may comprise or be a protrusion, which may protrude from the surrounding flat area and / or other portions of the cover.

[0012] The protrusion, at least its components, may protrude outwardly, where "outwardly" may be understood to mean away from the center of gravity of the cover and / or connector.

[0013] In other embodiments, the projections may project inwardly or may project tangentially or circumferentially.

[0014] The release element may be elongated, e.g. to allow easy assembly whilst keeping material and space requirements small. It may be elongated along the mounting direction of the cover, i.e. the direction in which the cover is mounted on the housing part.

[0015] To further simplify the assembly, the release element may be elongated in the connection direction of the connector. The connection direction of the connector may be parallel to the mounting direction of the cover. With this solution, the assembly is simple. The flow of forces during assembly is along the same direction, which is therefore advantageous. The connection direction should be understood as the direction in which the connector mates with a counter connector, e.g. a header.

[0016] The cover may comprise at least one further release element. In an advantageous development, the further release element is equivalent to the (first) release element when the cover is mounted on the housing part in a position rotated by 180°. This allows the use of the cover in different applications, for example when the cover defines an outlet for the cables. The cover can then be mounted in two different orientations, resulting in different positions and / or orientations of the outlet. In order to balance the force flows, the first release element and the at least one further release element are arranged with mirror symmetry on the cover.

[0017] In one possible embodiment, the translation blocking member of the lever lock is located at the free end of the lever lock. The stop surface may be the outermost surface or the front surface of the lever lock. Such a configuration can save space.

[0018] Multiple sequences for installing the cover and operating the lever may be possible.

[0019] In one development, the cover can be fitted when the lever is in the final position. This can be advantageous, since it can be easier to fit the cover once the lever is out of the way.

[0020] In a further development, the lever can be moved to a final position when the cover is attached, which can be advantageous if, for example, safety regulations should prevent the connector from mating with a mating connector without the cover being attached.

[0021] The assembly may only allow one of these two sequences, the other being precluded by suitable means such as a blocking member or the like.

[0022] However, to make assembly easier for the operator, both sequences may be possible.

[0023] To safeguard correct assembly and in particular to ensure that the lever is in its final position when the lever lock is moved, movement of the lever lock to the locked position may be blocked by a further pair of engaging translation blocking members on the lever and housing part respectively when the lever is close to, but not in, its final position, whereby movement is not possible when both the cover and the lever are close to, but not in, their desired positions, i.e. the final position of the lever and the correctly fitted position of the cover. The further pair should of course not block movement of the lever lock when the lever is in its final position.

[0024] The further pair may in particular be spaced apart from the first pair in a radial direction, which may be with respect to an axis of rotation about which the lever rotates relative to the housing part.

[0025] With respect to the other positions, the final position should not be understood as a single position in the strict mathematical sense, but rather as a small range of positions. This takes into account manufacturing and assembly tolerances and deviations. For example, the start and final positions may relate to a range of less than 5 degrees, preferably less than 3 degrees, in particular less than 1 degree. Similarly, the release and lock positions may relate to a range of less than 3 mm, preferably less than 1 mm, in particular less than 0.1 mm, if the lever lock moves in translation. However, the lever lock may also move in a rotational or mixed manner. In a broader sense, any position outside the final position may be considered as a start position and / or any position outside the release position may be considered as a lock position.

[0026] The range "close to" may be defined as a range of 5 degrees, 10 degrees or 20 degrees proximate to the (range of) final position.

[0027] In particular, the blocking by the further pair may be independent of the state of the cover, i.e. whether it is attached or not attached to the housing part.

[0028] In one embodiment, the lever lock is slidable relative to the lever when attached to the lever, which allows for easy and safe operation. The lever and / or the lever lock may comprise guide elements such as matching or complementary rails, tracks, pins and / or slits.

[0029] According to one development, the distance of the lever lock to the pivot axis of the lever is shorter in the locked position than in the released position. This allows the connector to be made more compact. The two can be connected in a telescoping manner, for example.

[0030] The distance of the lever lock relative to the axis of rotation of the lever may be constant during rotation of the lever relative to the housing part. Throughout the entire rotation, the lever lock may be in a released position.

[0031] To increase leverage, the lever lock may act as an extension of the lever when in the released position. For example, the radially outer or distal end of the lever lock may be farther from the axis of rotation of the lever than the radially outer or distal end of the lever. For example, this difference may be at least 10%, preferably at least 20%. When the lever lock is in the locked position, this difference may be less or near zero.

[0032] The lever lock may comprise an actuator configured for actuation of the lever and lever lock combination by a user or a machine. For example, the actuator may comprise a drive surface that is substantially perpendicular to the path of the actuator during rotation of the lever. The configuration may be such that it is operable by a test hand or finger. The test hand or finger may be defined in a standard or specification that may be set nationally, internationally, by a company or by a consortium.

[0033] The lever lock and housing part may include a pair of mating rotation blocking members for blocking rotation of the lever out of its final position when the lever lock is in the locked position, and thus blocking is at least indirect via the lever lock.

[0034] In one embodiment, the lever lock may comprise a blocking member forming one of a further pair of mating translational blocking members and one of a mating rotational blocking members, thus having a dual function and reducing the complexity of the connector.

[0035] The blocking member may have a variety of shapes. It may be formed as a protrusion, a web, a pin, or a collar.

[0036] To provide even greater security and in particular to secure the lever in its final position when it is not yet possible to move the lever lock to the locked position, the assembly may comprise a further second lever lock to prevent movement of the lever out of its final position.

[0037] This second lever lock may be closer to the axis of rotation to keep space requirements to a minimum. Since the second lever lock is primarily used when the connector is not yet mated with the mating connector and therefore the forces are smaller, a position closer to the axis of rotation may be sufficient for locking at this stage.

[0038] In one embodiment, the second lever lock is translationally movable. For example, the second lever lock may be configured to be operated along a direction parallel to the axis of rotation. Such operation of the second lever lock may result in little interference with other assembly, mounting and / or mating operations. The second or further lever lock may be slidably held in the housing part parallel to the axis of rotation.

[0039] The second lever lock may be separate and / or independent from the first lever lock.

[0040] In one advantageous embodiment, the further lever lock may be configured to prevent mating of the connector with a mating connector when in the locked position. Such a dual function may reduce complexity. To achieve such prevention, the further lever lock may for example protrude from the housing part in the locked position.

[0041] The lever and lever lock may be separate elements. They may be made from different materials depending on the application. To keep the design simple, the lever, lever lock, housing part and second lever lock, if present, may each be a single integral piece.

[0042] The connector may comprise further components, such as terminals, terminal blocks, further housing parts and / or further covers or cover parts.

[0043] The housing part may form a receptacle for the terminal or terminal block, in other embodiments the receptacle may be located in a further housing part of the connector.

[0044] The further lever lock may be configured to lock the terminal or terminal block to the part forming the receptacle, e.g., the housing part. Such additional functionality increases security while keeping the complexity to a reasonable level. The terminal or terminal block may prevent movement of the further lever lock when it is improperly or insufficiently inserted.

[0045] The lever may be part of a locking mechanism for locking the connector to a mating connector.

[0046] In one embodiment, mating of the connector with the mating connector is only possible when the lever is in the starting position.

[0047] Additionally or alternatively, the lever may be part of a drawing mechanism for drawing the connector to a mating connector. The connector may include a gear system, among other things, for transmitting force or configuring for an application.

[0048] The start and final positions may each be an end position of rotation, which may be defined by stop surfaces on the lever and / or the housing part.

[0049] The invention will now be described in more detail and by way of example only with the aid of advantageous embodiments and with reference to the drawings, in which the described embodiments are merely possible configurations, in which the individual features mentioned above may be provided independently of one another or may be omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0051] The drawings show one embodiment of an assembly 101 for a connector 100. The connector 100 shown is shown merely as an example electrical connector 100. Other types of connectors 100, such as fiberglass connectors, can also be improved with the solutions shown.

[0052] The assembly 101 comprises a housing part 20 which may serve as a base element, a support element and / or a protective element for further components of the assembly 101. The housing part 20 comprises a terminal block receiving part 21 which is configured in particular for the insertion of a terminal block 85. In the described embodiment, four different types of terminal blocks 85 are used, each having a coding element 86 which projects laterally (i.e. along the second transverse direction T2) at different positions along the first transverse direction T1. As a result, only suitable terminal blocks 85 can be inserted into each terminal block receiving part 21. Terminals (not shown) may be inserted into the terminal receiving parts in the terminal block 85. In other embodiments, the terminals may be inserted directly into the terminal receiving parts in the housing part 20.

[0053] The terminal block 85 may be inserted into the housing part 20 along an insertion direction I, which in the illustrated example is parallel to a connection direction C in which the connector 100 mates with a mating connector 200. Here, the mating connector 200 is shown only diagrammatically together with the housing part 220.

[0054] The assembly 101 further comprises a cover 50 which may be attached or mounted to the housing part 20 when the terminal block 85 with the terminals and cables attached thereto is inserted into the housing part 20. The cover 50 may be mounted along a mounting direction M which, in the example described, is parallel to the insertion direction I and the connection direction C. An opening allowing the removal of the cable from the receptacle defined by the cover 50 opens laterally in the mounted state 51.

[0055] The cover 50 is provided with latch elements 52 which, in the mounted state 51 of the cover 50 , engage corresponding latch elements 25 in the form of projections 26 on the housing part 20 , thereby securing the cover 50 to the housing part 20 .

[0056] The lever 30 of the assembly 101 is part of a locking mechanism 120 for locking the connector 100 to the mating connector 200 and part of a drawing mechanism 130 for drawing the connector 100 into or towards the mating connector 200. The lever 30 comprises a receiving portion 139 for engaging a counter or mating element, not shown, in the mating connector 200. In a starting position 31 of the lever 30 (e.g. shown in FIG. 2), the counter element may be inserted into the receiving portion 139. The lever 30 may then be rotated along a rotation direction D, which is tangential to the rotation axis 24, towards a final position 32 of the lever 30. In this final position 32, the receiving portion 139 and the counter element are shape-locked along a connection direction C.

[0057] The lever 30 rotates about a rotation axis 24 that extends through the center of an axle 22 formed by the housing 20. The axle 22 is configured as a short pin 23 that projects laterally along a second lateral direction T2 away from the rest of the housing part 20 and is located in a corresponding recess in the lever 30 when the lever 30 is attached to the housing part 20. The pin 23 and the lever hole are shaped as a key and keyhole to allow mounting in one orientation and to prevent the lever 30 from moving away from the housing part 20 in the second lateral direction T2 outside that one position.

[0058] The lever 30 comprises a toothed portion 132 for transmitting motion to a further element 135 which further secures the connector 100 to the mating connector 200. The further element 135 also comprises a receiving portion 139 and a toothed portion 132 and rotates around a further axle 22 formed by the housing 20.

[0059] The assembly 101 includes a lever lock 40 configured to prevent rotation of the lever 30 out of the final position 32 when the lever lock 40 is in the locked position 42, and to allow rotation of the lever 30 when the lever lock 40 is in the released position 41. The lever lock 40 is not free to move from the released position 41 to the locked position 42. During normal operation, the lever lock 40 is movable to the locked position 42 only when the lever 30 is in the final position 32 and the cover 50 is in the properly installed position or condition 51.

[0060] In particular, the assembly 101 comprises a pair of engaging translation blocking members 63, 64 on the lever 30 and on the lever lock 40, respectively. If at least one of the two conditions is not met, i.e. the lever 30 is not in the final position 32 and / or the cover 50 is not in the mounted state 51, a stop surface 46 arranged on the outermost or front side of the free end 47 of the arm 44 of the lever lock 40 abuts against a stop surface 37 on the lever 30. To disengage the two translation blocking members 63, 64, the cover 50 forms a release element 54 configured as a protrusion 53 that elastically bends the free end 47 of the arm 44 when the cover 50 is in the mounted state 51. In the illustrated embodiment, the blocking member 63 is arranged on a dedicated small section of the arm 44 that is thinner than the rest of the arm 44 and inclined relative to it.

[0061] The release element 54 projects away from the rest of the cover 50 along a second lateral direction T2 and is formed as an elongated protrusion 53 extending along a mounting direction M of the cover 50. The mounting direction M is parallel to the connection direction C in order to maintain the same assembly direction throughout the assembly procedure.

[0062] In the presently preferred embodiment, the cover 50 actually comprises four similar release elements 54, which are pairwise equivalent to each other with respect to a 180° rotation and pairwise mirror images of each other, so that the cover 50 and lever 30 can be attached or mounted to the housing part 20 in a variety of orientations, with at least one release element 54 in the appropriate position in each orientation.

[0063] To further improve safety, the assembly 101 comprises further translational blocking members 67, 69 arranged on the housing 20 and on the lever lock 40, respectively. These further translational blocking members 67, 69 help to avoid undesired movements of the lever lock 40, in particular when the cover 50 is close to but not in the mounted state 51 and the lever 30 is close to but not in the final position 32. As can be seen for example in FIG. 6, the blocking by the further translational blocking member 67 of the housing 20 and the further translational blocking member 69 of the lever lock 40 is only released when the lever 30 is in the final position 32. Only in the final position 32 can the blocking member 66 with the further translational blocking member 69 of the lever lock 40 be inserted into the receiving portion 92 on the housing 20. The further pair of translation blocking members 67, 69 are spaced apart from the first pair of blocking members 63, 64 in a radial direction R. "Radial direction R" refers to a set of directions perpendicular to the axis of rotation 24.

[0064] The blocking by the further pair of blocking members 67, 69 is independent of the state of the cover 50, i.e. whether it is correctly mounted or not. In the example shown, the cover 50 can be mounted when the lever is in the final position 32, and the lever 30 can be moved to the final position 32 when the cover 50 is mounted. This allows flexibility in the assembly process. In alternative embodiments, for example to increase safety, only one of the two mounting sequences may be possible.

[0065] Once the blocking by the translation blocking members 63, 64, 67, 69 has been released or overridden, the lever lock 40 can be moved manually or mechanically from the released position 41 to the locked position 42. Rotation of the lever 30 relative to the housing part 20 is indirectly blocked in the locked position 42 by the lever lock 40 acting as an intermediate element. A rotation blocking member 72 on the housing 20 engages with a rotation blocking member 74 on the lever lock 40. Rotation of the lever 30 relative to the lever lock 40 is also not possible due to a form fit between the two, i.e. due to the engagement of guide surfaces 34, 43 on the lever 30 and on the lever lock 40 respectively. The guide surfaces 34, 43 together form a guide device 35 which allows a guided sliding of the lever lock 40 relative to the lever 30 by translation.

[0066] The rotation blocking member 74 of the lever lock 40 is part of the blocking member 66 which also forms the translation blocking member 64. To save space, the blocking member 66 is constructed as an inwardly projecting plate-like projection. It forms a corner of the lever lock 40. At the blocking member 66, the thickness of the lever lock 40 is significantly smaller than in the adjacent parts.

[0067] The lever 30 and lever lock 40 are separate elements that may be made from different materials depending on the desired functionality.

[0068] The distance 142 of the lever lock 40 relative to the pivot axis 24 in the locked position 42 is less than the distance 141 of the lever lock 40 relative to the pivot axis 24 in the released position 41. Thus, the connector 100 is more compact in the locked position 42, which is typically the position that the lever lock 40 will assume during normal operation of the connector 100 in the end product. In other configurations, this may be reversed, or the distance may remain the same in the two positions 41, 42.

[0069] During rotation of the lever 30 relative to the housing part 20, the distance of the lever lock 40 relative to the axis of rotation 24 of the lever 30 remains constant. During this rotation, the lever lock 40 remains in the release position 41.

[0070] In the illustrated embodiment, the lever lock 40 functions as an extension 95 of the lever 30 when in the released position 41. The extension 95 extends the lever length. In the released position 41, the length 48 from the pivot 24 to the outermost or distal end 49 of the lever lock 40 is longer than the length 38 from the pivot 24 to the outermost or distal end 39 of the lever 30. In the locked position 42, the difference between the lengths 38, 39 is smaller and is approximately zero.

[0071] Disposed on the lever lock 40 is a drive 94 configured for actuation by a human or machine.

[0072] The assembly 101 comprises a further or second lever lock 80 for preventing movement of the lever 30 out of the final position 32. The second lever lock 80 is formed as a beam or bar that is slidably held parallel to the axis of rotation 24 in a complementary elongated receiving part in the housing part 20. The second lever lock 80 is configured to be operated by moving it along a drive direction A parallel to the axis of rotation 24 from a locked position 89, in which it locks the lever 30 in the final position 32, to a released position 88, in which its blocking effect on the lever 30 is absent. In the locked position 89, a rotation blocking member 81 in the second lever lock 80 blocks movement of a corresponding blocking member 83 in the lever 30. To keep the design simple, in each case the second lever lock 80 and a part of the lever 30 act as blocking members 81, 83. The perpendicularity of the drive direction A and locking direction L of the (first) lever lock 40 reduces the risk of unintended or accidental release, which may occur for example due to vibrations.

[0073] The second lever lock 80 is separate from the (first) lever lock 40 and is located closer to the axis of rotation 24. This takes into account that the second lever lock 80 is used to keep the lever 30 in the final position 32 when the terminal block 82 is being inserted but the connector 100 is not yet mated with the mating connector 200. At this stage, the forces are still small and fixing by the second lever lock 80 alone is possible. When all parts of the connector 100, including the cover 50, are installed, the connector 100 can be mated with the mating connector 200. The forces acting at this stage are larger and therefore, due to the law of leverage, a position of the (first) lever lock 40 further away from the axis of rotation 24 is favored. It is not necessary at this stage to have the second lever lock 80 in the locked position 89. Rather, it can be used to secure the terminal block 85 in place within the housing part 20, as will be explained below.

[0074] The further lever lock 80 may affect the insertability of the terminal block 85 into the receiving portion 21 in the housing part 20. For example, full insertion may only be possible when the second lever lock 80 is in the locked position 89. Also, the terminal block 85 may prevent movement of the second lever lock 80 back to the released position 88 if it is inserted improperly or to an insufficient depth. Movement of the second lever lock 80 may be enabled or permitted once they have reached the desired insertion depth.

[0075] 1 and 3, the further lever lock 80 is configured to prevent mating of the connector 100 with the mating connector 200 when in the locked position 89. It protrudes from the housing part 20 when out of the released position 88. In the locked position 89, it protrudes to an extent that it prevents insertion of the connector 100 into the housing part 220 of the mating connector 200.

[0076] The illustrated exemplary embodiment comprises a third lever lock 90, which similarly prevents the lever 30 from moving in the final position as the first lever lock 40. A bendable latch arm 99 on the lever 30 automatically latches behind a corresponding latch element 29 formed as a wedge-shaped protrusion 28 on the housing part 20. Thus, unlike the first lever lock 40 and the second lever lock 80, the third lever lock 90 forms a direct connection (without intervening elements) between the lever 30 and the housing part 20. This allows for reduced tolerances or hysteresis due to the reduced number of parts involved. Furthermore, the third lever lock 90 can lock the lever 30 before the lever lock 40 moves to the locked position 42.

[0077] Both the lever 30 and the lever lock 40 have a U-shape. Two arms 33, 44 are connected by a bridge portion 36, 45.

[0078] In order to achieve an advantageously symmetrically balanced force flow, the lever 30, lever lock 40, cover 50 and housing part 20 are of mirror symmetry.

[0079] Although not shown here, the lever lock 40 may also be mirror-symmetric with respect to a second plane of symmetry perpendicular to the first plane of symmetry. The resulting lever lock 40 may then be invariant to a 180 degree rotation. This further simplifies the assembly process since the lever lock 40 may be installed in two equivalent rotational orientations, eliminating an orientation step for the assembler. However, it may be necessary to adapt the other components 20, 30 of the connector 100 to such a modified lever lock 40. [Explanation of symbols]
