Definitions

  • the present invention relates to a terminal block.
  • a clamping module in the form of a spring strut for plug-in connection in a plug-in connection system in a space which is defined by a longitudinal direction, a transverse direction transverse to the longitudinal direction and a height direction is spanned transversely to the longitudinal direction and transversely to the transverse direction.
  • the well-known clamping module comprises a first module part, which has a first plug-in connection element on the upper side, and a second module part with an interior space which is delimited by a wall on both sides in the longitudinal direction and the transverse direction and on the underside in the vertical direction, with the second component part on the underside has a second connector element.
  • the second building block part is designed to be larger than the first building block part both in the longitudinal direction and in the transverse direction, with the first building block part being pushed telescopically against the height direction into the interior of the second building block part.
  • the two component parts are supported against one another via a common restoring element.
  • the object of the invention is to improve the known terminal block.
  • the specified clamping block is based on the consideration that the well-known clamping block as a spring strut is very slim, but also very individually constructed. It cannot be installed with other terminal blocks without additional coupling elements, because the both connectors are not complementary.
  • the specified clamping block comes into play with the idea of cutting open a clamping block with a grid dimension according to Hilary Page and used by Lego A/S since 1955 and storing the two parts telescopically in relation to one another via a spring.
  • Such a terminal block is not only fully compatible with the grid dimension, it can also be connected to other terminal blocks that are defined according to this grid dimension without additional coupling elements.
  • the wall of the second block part has, on its surfaces facing the interior, block part interlocking elements directed into the interior, which guide the first block part in the vertical direction and block movement of the first block element in the longitudinal direction and the transverse direction. In this way, the friction between the two parts of the building block during the telescopic movement can be reduced.
  • a relative movement path of the first building block part in the second building block part is limited in the height direction by a limiting device. In this way, it is not only possible to prevent the two component parts from detaching from one another unintentionally, the two component parts can also be stored against one another with a definable preload.
  • the limiting device has a snap-hook connection made up of a first hook, which is formed on the wall of the first block part, viewed from the interior, and directed outwards, and a second hook, which is formed on the wall of the second block part, viewed from the interior inwards is designed aligned on.
  • the wall of the first block part is slotted next to the first hook.
  • the elasticity of the first hook can then be adjusted by the width of the slot, so that the movement limiter can be designed to be mechanically sufficiently stable on the one hand, but still remains detachable.
  • the wall of the second block part has an access opening on the underside in the area of the second hook to the interior, through which the hooks are then accessible in order to easily release the movement limitation.
  • the restoring element is a spring, which can not only be produced inexpensively but can also be implemented with any desired elasticity.
  • the specified clamping module includes a guide sleeve in which the spring is guided in the vertical direction. In this way, unintentional buckling of the spring is avoided, as a result of which the restoring function of the spring would no longer be provided.
  • the guide sleeve is attached to the first component part or to the second component part. In this way, the spring can be stored stably in the interior space between the two building block parts on one of the two building block parts.
  • hook form-fitting elements are formed on the guide sleeve, which guide a hook in the vertical direction and restrict movement of the hook towards the guide sleeve. This will avoid overstretching the above hooks.
  • the clamping module 2 comprises a first module part 10 and a second module part 12.
  • the first building block part 10 has an interior 14 which is delimited in and counter to the longitudinal direction 4 and in the transverse direction 6 by a wall 16 which forms a square with an edge length 15 in the cross section seen from the vertical direction 8 .
  • the edge length 15 is only in for the sake of clarity 1 implied.
  • the interior space 14 of the first component part 10 is delimited by a cover 17, on the upper side of which first plug-in connection elements in the form of knobs 18 are formed.
  • the Nubs 18 are sized and spaced according to Lego grid dimensions, such as disclosed in the disclosure, for example Pawel Sariel Kmiec, The Unofficial LEGO Technic Builder's Guide, No Starch Press; 2nd edition (October 1, 2016), ISBN: 978-1593277604 is described.
  • Lego grid dimensions such as disclosed in the disclosure, for example Pawel Sariel Kmiec, The Unofficial LEGO Technic Builder's Guide, No Starch Press; 2nd edition (October 1, 2016), ISBN: 978-1593277604 is described.
  • Lego grid dimensions such as disclosed in
  • the wall 16 of the first building block part 10 has a recessed wall section 19 on both sides, viewed in the transverse direction 6 , which is arranged centrally when viewed in the longitudinal direction 4 and is directed towards the interior 14 .
  • the recessed wall section 19 is recessed into the wall 16 with a recessed depth 20 .
  • the reset depth 20 is only in for the sake of clarity 2 implied.
  • the recessed wall section 19 is delimited from the rest of the wall 16 by slots 22 and has a hook 24 on its underside viewed in the height direction 8.
  • the second building block part 12 also has an interior space 26, which is delimited by a peripheral wall 28 in and counter to the longitudinal direction 4 and in the transverse direction 6.
  • the interior space 26 of the second building block part 12 is in the form of a square with an edge length 27 in its cross section seen from the vertical direction 8 .
  • the interior space 26 of the second component part 12 is delimited by a base 30, on the underside of which second plug-in connection elements are formed in the form of nub receptacles 32, as are fundamentally evident from the disclosure US 3,005,282A are known.
  • the geometry of the nub mounts 32 is matched to the nubs 18 in accordance with the Lego grid dimension.
  • the edge length 15 of the square first building block part 10 is selected to be smaller than the edge length 27 of the square interior space 26 of the second building block part 12, so that the first building block part 10 can be inserted telescopically into the interior space of the second building block part 12.
  • component interlocking elements 32 can be formed, which restrict a movement of the corresponding other building block part 12, 10 in the longitudinal direction 4 and the transverse direction 6.
  • these component form-fitting elements 32 are formed on the wall 28 in the interior 26 of the second component part 12 .
  • two form-locking component elements 32 are arranged on each side of the above-mentioned square, while viewed in the transverse direction 6, only one form-locking component element 32 is arranged on each side of the above-mentioned square.
  • a single component form-fitting element 32 is sufficient on each side to achieve the desired form-fitting connection in the longitudinal and transverse direction 4 , 6 and thus guidance in the vertical direction 8 .
  • the arrangement of two component form-fitting elements 32 on one side is recommended so that, despite the hook 24 on the first component part 10, stable guidance between the two component parts 10, 12 can be achieved.
  • a hook 34 is formed on each side of the square with two component form-fitting elements 32, and a guide channel 36 adjoins the underside thereof, viewed in the vertical direction 8. If the first building block part 10 is pushed telescopically into the interior space 26 of the second building block part 12 counter to the height direction 8, the hooks 24, 34 of the respective building block parts 10, 12 are aligned with one another. From a certain immersion depth of the first building block part 10 into the second building block part 12, the hooks 24 of the first building block part 10 snap over the hooks 34 of the second building block part 12 and thus form a positive connection in the vertical direction 8, so that the first building block part 10 no longer forms can be detached from the interior 26 of the second component part.
  • the second Building block part 12 has an access opening 38 on its base 30 on each side of the square with two component form-fitting elements 32, through which a lever (not shown) can be pushed and the hook 24 of the first building block part 10 can be raised in or against the transverse direction 6.
  • the first building block part 10 can then be detached again from the interior space 26 of the second building block part in the vertical direction 8 .
  • a guide sleeve 40 is also arranged on the bottom 30 of the second component part 12 .
  • a restoring element in the form of a spring 42 can be pushed into this guide sleeve 40 and serves as a restorable spacer between the cover 17 of the first component part 10 and the base 30 of the second component part 12 .
  • the length of the spring 42 is dimensioned such that when the hooks 24, 34 strike one another in the vertical direction 8, the spring 42 is subjected to a predetermined prestressing force. If the cover 17 is subjected to a force counter to the vertical direction 8 , the first component part 10 is pressed further into the interior space 26 of the second component part 12 .
  • the spring 42 moves the first building block part 10 back out of the interior space 26 of the second building block part 12 until the hooks 24, 34 strike one another again in the vertical direction.
  • a damping function can be achieved which is arbitrarily scalable by stacking or arranging several of the clamping blocks 2 side by side, because a parallel arrangement of the clamping blocks 2 increases the overall spring constant and a series arrangement of the clamping blocks 2 reduces the overall spring constant.
  • the guide sleeve 40 can be arranged loosely between the cover 17 of the first component part 10 and the bottom 30 of the second component part 12 . However, it is preferably attached either to the cover 17 of the first component part 10 or to the bottom 30 of the second component part 12 .
  • the guide sleeve 40 is attached to the base 30 of the second building block part 12 and also has shoulder-shaped hook form-fitting elements 44 which are attached to the hooks 34 of the second block part 12 are directed to. In this way, a movement space for the hooks 24 of the first building block part can be defined between each hook 34 of the second building block part 12 and the corresponding hook form-fitting element 44 in order to avoid overstretching, for example.
  • the spring 42 is first pushed into the guide sleeve 40 on the bottom 30 of the second component part 12 .
  • the first building block part 10 is then inserted with its hooks 24 first and aligned with the hooks 34 of the second building block part 12 into the interior space 26 of the second building block part 12 until the hooks 24, 34 latch into one another.
  • the clamping block 2 can be used, for example, as a damping element in a higher-level clamping block model.
