Description

Technical Field

[0001] The present invention relates to a current collector, particularly for supplying electrical energy and / or data to an electrical load that can move along a sliding contact line. Background Technology

[0002] The current collector mentioned at the beginning has long been known. Document DE 20 2016 105 157 U1 discloses a current collector for an electrical load, comprising at least one sliding contact carrier for contacting at least one conductive conductor profile of a sliding contact line, wherein the sliding contact can be electrically connected to an electrical connection terminal of the electrical load. If the sliding contact is exhausted, it must be replaced by maintenance personnel. This usually requires loosening and reconnecting the cable link, which is time-consuming and requires experienced personnel, resulting in long downtime.

[0003] Document DE 16 13 919A relates to a current collector having a current collector housing, which is a single piece made of insulating material. An elongated recess is formed in the upper side of the housing to accommodate the lower portion of a clog / contact shoe. Two curved claws, spaced apart from each other, extend upward from the bottom of the recess and grip the lower portion of the clog. The upper inner portions of the claws and the sidewalls of the clog are constructed with interlocking protrusions and grooves, thereby retaining the clog within the recess. When installing the clog, the claws are slightly moved outward until the protrusions and grooves align. In this position, the claws spring inward, thus securing the clog within the current collector housing. The current collector housing therefore has no metal parts because it consists of a single piece, and the clog can be easily replaced. In addition, the clog contacts the conductive rail on one side and the electrical conductor of the current collector housing on the other side, which is connected to the lower part of the clog by means of a U-shaped clamping device. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a current collector that enables simple, quick and tool-free replacement or substitution of contacts.

[0005] This invention achieves this objective by means of a current collector having the features of claim 1. Advantageous designs and suitable modifications of the invention are given in the dependent claims.

[0006] The current collector according to the invention has a base member and a replaceable / replaceable member detachably connected to the base member.

Here, the locking device may advantageously have a locking opening on the base component and a locking pin on the replaceable component that can be inserted into the locking opening, or conversely, the locking device may have a locking opening on the replaceable component and a locking pin on the base component that can be inserted into the locking opening. In particular, a movable locking protrusion on one component can be inserted into and locked into a locking stop on another component. Furthermore, the locking pin may form a pin for connecting the unit, and the locking hole may form a channel for the quick-connect unit described above and below.

[0010] Preferably, the first contact can be pressed toward the corresponding contact by means of a clamping member provided on the replaceable part.

[0011] Furthermore, it is advantageous to provide a second contact on the replaceable part, specifically on the side opposite to the first contact, which constitutes an electrical connection contact. Here, the first and second contacts can preferably be constructed as independent, separate components.

[0014] Furthermore, advantageously, the second contact can be pressed towards the connecting contact of the base member by an interchangeable member using another clamping member. This other clamping member can also be formed from the clamping members described above and below. In this respect, this single clamping member thus has a dual function for both contacts.

[0015] Preferably, a suction port may be provided in the base component and a corresponding other suction port may be provided in the replaceable component for sucking out the debris of the one or more contacts from the replaceable component.

[0016] Furthermore, the replaceable component may preferably have a housing in which the one or more contacts are disposed, and particularly protruding outward through connection-corresponding contact openings and / or contact openings of the housing for contact with corresponding contacts and / or connection points of the base component.

[0017] Preferably, the connecting contact points, the corresponding connecting contacts, and / or the contacts can be oriented along the insertion direction of the replaceable part into the base part.

[0018] Preferably, the corresponding contacts and / or contacts can be disposed in a groove-shaped recess of the replaceable part, the recess preferably extending over the entire length of the replaceable part.

[0019] Advantageously, the replaceable component may have an observation port for connecting a wear indicator to the corresponding contact and / or contact point, the wear indicator indicating the degree of wear of the corresponding contact and / or contact point.

[0020] Preferably, a disengagement device is provided, which switches the connection contact to a voltage-free state when the locking structure is open.

[0023] Alternatively, the corresponding contacts can be charging contacts at a fixed charging station, while the current collector can be installed on a movable electrical load.

[0024] The alternative current collector has a base member for fastening to an electrical load movable along the longitudinal direction of the sliding contact line and a replaceable member detachably connected to the base member, wherein the replaceable member has at least one first sliding contact for electrical contact with a conductive sliding contact line profile of the sliding contact line, the base member has an electrical connection contact and the replaceable member has an electrical connection corresponding contact electrically connected to the electrical connection contact, and the connection contact of the base member can be connected to the electrical connection line of the electrical load.

[0035] Figure 8 The current collector with an alternative third fast connection is shown in the corresponding configuration. Figure 2 A three-dimensional schematic diagram. Detailed Implementation

[0036] Figure 1 A current collector 1 with a base component 2 is shown, which is electrically connected to an electrical connection line 3, 3' of an electrical load (not shown), and the base component 2 is fastened to the electrical load. The current collector 1 can be connected in a manner known to itself along only... Figure 1b The sliding contact line 100, as indicated in the diagram, is moved along its longitudinal direction L to supply electrical power to the electrical load. This design is commonly used in principle by those skilled in the art.

[0037] To electrically connect the electrical load to the sliding contact line profile (not shown in the attached drawings) of the sliding contact line 100 via the base member 2, a replaceable member 4 is provided. The replaceable member 4 can be quickly connected to the base member 2 via a quick-connect unit 5 (exemplarily in the form of a dovetail joint unit) provided in the connecting section 2a of the replaceable member 4. For this purpose, the connecting section 2a of the base member 2 has a connector 6 of the dovetail joint unit, and a first connecting counterpart 7 of the dovetail joint unit provided on the replaceable member 4 can be pushed into this connector in the pushing direction E. This allows the replaceable member 4 to be quickly connected to or removed from the base member 2. The design of the connector 6 and the connecting counterpart 7 can also be interchanged if necessary.

[0038] In order to ensure that the replaceable part 4 and the base part 2 can be fixedly connected during operation, and can also be loosened for maintenance and replacement, a method is provided in the L-shaped bend of the end side 2b of the base part 2 relative to the connecting section. Figure 2The locking hole 8 is visible in the image. The end side 2b also serves as a stop for the replaceable part 4. If the replaceable part 4 is pushed onto the base part 2, the locking pin 9, which protrudes from the end side 4a of the replaceable part 4 extending laterally in the insertion direction, can engage with the locking hole 8. The locking pin 9 is hollow and has a locking protrusion 10 at its end that engages with the locking hole 8, which is movable radially outward from its interior in a radial hole in the locking pin 9. The locking protrusion 10 is radially outward under the action of a spring in the normal state. Because the locking protrusion 10 is wedge-shaped and inclined forward in the insertion direction into the locking hole 8, the locking protrusion 10 is first pressed downward against the spring force when pushed in and then snaps into the countersunk portion provided for this purpose when it reaches the countersunk portion provided for this purpose in the locking protrusion 10. To loosen the now locked connection, follow the instructions... Figure 2 A locking button 11 is provided on the end side 4b opposite to the end side 4a on the base side of the replaceable part 4. If the locking button 11 is pressed, the locking protrusion 10 sinks into the locking pin 9 and the replaceable part 4 can be pulled out from the base part 2.

[0039] The locking structure formed by the locking hole 8, locking pin 9, locking protrusion 10 and locking button 11 can also be designed in other ways. For example, a pin can be provided in the end side 2b of the base member 2, which engages with the locking hole 8 from above. This pin can then be inserted into the corresponding hole in the locking pin 9 in the installed state of the replaceable part 4.

[0040] An alternative quick-connect unit with an alternative locking structure is available. Figure 4 and 5 As shown in and in Figures 1 to 3 and Figures 6 to 7 The difference between the quick-connect unit shown and the one described above is mainly the interchange of the locking pin 9 and locking hole 8; therefore, this difference will be discussed primarily below. For the same or corresponding parts, the same as in... Figures 1 to 3 The same reference numerals are used in the locking structure shown in the figure.

[0041] In the alternative locking structure, a significantly longer locking pin 9a is provided, which is disposed on the bent end side 2b in the base member 2, as in... Figure 5 Clearly visible in the image. At the free end of the locking pin 9a, the locking pin 9a also has a movable locking protrusion 10a, as described above, which operates in the same manner, but appears different from when viewed from above. Figures 1 to 3 The locking protrusion 10 rotated 180°.

[0042] When assembling the replaceable part 4, the locking pin 9a is pushed through the locking channel 8a that penetrates the replaceable part 4 in the pushing direction E. The length of the locking pin 9a is such that the locking protrusion 10a extends from the locking channel 8a when the replaceable part 4 is fully pushed in and bounces off the rear end side 4b facing away from the base member 2, thus reliably locking the replaceable part 4 onto the base member 2. A certain gap is allowed in the pushing direction E, as electrical connection is still ensured even so, as described in detail later. The stop on the replaceable part 4 necessary for the locking protrusion 10a can also be constructed in other ways, for example, provided within the replaceable part 4.

[0043] The longer locking pin 9a and the through locking channel 8a together form an alternative quick-connect unit 5a, because the replaceable part 4 can be pushed into its final locked assembly position along the push-in direction E.

[0044] exist Figure 4 and 5 The alternative design of the quick-connect unit 5a described herein has the following advantages: it eliminates the need for additional components for the quick-connect unit, and the locking protrusion 10a can be operated manually from the outside without tools in the final assembled state of the replaceable part 4, thereby further simplifying the replacement of the replaceable part 4. Furthermore, this alternative quick-connect unit 5a is less susceptible to contamination by debris from the sliding contacts 14, 14'.

[0045] To establish an electrical connection between the electrical load and the sliding contact line 100, the base component 2 has connection points 12 and 12' on the right and left sides of the connector 6 along the longitudinal direction L. These connection points, in the assembled state of the base component 2 and the replaceable component 4, are respectively connected to corresponding points on the replaceable component 4. Figure 3 The clearly visible connection between contacts 13 and 13' forms an electrical connection.

[0046] The corresponding contacts 13 and 13' extend in groove-shaped recesses 4c and 4c', which are located on one side of the replaceable part (the lower side 4u of the replaceable part 4 in the figure). The recesses extend from the end side 4a on the base side to the opposite end side 4b along the entire length of the replaceable part 4 so that they can be pushed over the connecting contacts 12 and 12' that protrude slightly from the connecting section 2a.

[0047] On the side of the replaceable component 4 opposite to the corresponding connecting contacts 13, 13' (the upper side 4o of the replaceable component in the attached figure), upwardly protruding sliding contacts 14, 14' are provided, which are configured for electrical connection with the sliding contact line 100. The sliding contacts 14, 14' are constructed corresponding to the corresponding connecting contacts 13, 13' and also extend in the groove-shaped recesses 4c”, 4c”’ in the upper side 4o of the replaceable component 4, which are opposite to the recesses 4c, 4c'.

[0048] However, when necessary, the contact points 12 and 12' can also be flush with the surface and incorporated into the connecting section 2a, thereby eliminating the need for the grooved recesses 4c, 4c', 4c”, and 4c”’ in the replaceable part 4, as in Figure 6 The alternative design shown is as shown in the example. Figures 1 to 3 The only difference is between the implementation scheme shown in the diagram.

[0049] Preferably, the connecting contacts 12, 12', the corresponding connecting contacts 13, 13', and the sliding contacts 14, 14' can extend along the push-in direction E of the replaceable member 4 into the base member 2. Advantageously, the sliding contacts 14, 14' can also extend along the longitudinal direction L of the sliding contact line 100. Preferably, the push-in direction E extends along the longitudinal direction L. However, if necessary, the push-in direction E can also be oriented in other ways, for example, the replaceable member 4 can also be configured such that the replaceable member can be pushed onto the base member from the side, i.e., transverse to the longitudinal direction L and preferably transverse to the feed direction Z, or in another alternative design, pushed onto the base member 2 from above or below along the feed direction Z.

[0050] In a simple design, sliding contacts 14, 14' can be directly electrically connected to the corresponding contacts 13, 13' in the replaceable part, thereby establishing direct and permanent contact with the connecting lines 3, 3'. However, this poses a danger when replacing the replaceable part 4: maintenance personnel may come into contact with the upward-open sliding contacts 14, 14' that are connected to the electrical load, posing a risk of electric shock.

[0051] To prevent this, in the advantageous design shown in the accompanying drawings, the corresponding contacts 13, 13' and the sliding contacts 14, 14' are not directly electrically connected to each other, but this only occurs when the replaceable part 4 is installed in the base part 2, as described below.

[0052] Therefore, a system is established in Figure 2 and 3 Visible in the image are the first protective contact pin 17 and the second protective contact pin 17', electrically connected to each other in the end side 2b of the base component 2, stacked along the height direction toward the sliding contact line 100, on the base side, while the replaceable component 4 has corresponding protective contact pins 17'. Figure 1 The first and second protective contacts 18 and 18' are clearly visible and interchangeable. The protective contacts 18 and 18' are spring-loaded in the end side 4a, allowing the protective contact pins 17 and 17' on the base side to engage with the openings of the protective contacts 18 and 18' and provide electrical contact with them. Here, the first protective contact 18 is electrically connected to the corresponding contact 13, while the second protective contact 18', located above it, is electrically connected to the sliding contact 14, for example, via... Figure 1a and1b The flexible circuit is marked in the middle.

[0053] If the replaceable part 4 is now installed into the base part 2, then only when the replaceable part 4 is substantially completely pushed into the base part 2, will the electrical connection between the electrical connection line 3 and the sliding contact 14 be established through the connecting contact point 13, the connecting corresponding contact point 14, the first protective contact point 18, the first protective contact pin 17, the second protective contact pin 17' and the second protective contact 18'.

[0054] The electrical connection between the electrical connection line 3' and the sliding contact 14' is achieved as described above by connecting contact 13' and connecting corresponding contact 14', without the need to provide detailed reference numerals for the corresponding protective contact pins and protective contacts shown.

[0055] As in Figure 1 Clearly visible in the image, the replaceable part 4 has a basically box-shaped design, with its opposing upper and lower sides symmetrically constructed. Figure 1 The upper part of the middle is located on the upper side, and the replaceable part 4 has a second connecting counterpart 7', which is opposite to the first connecting counterpart 7 of the dovetail groove connecting unit 5 on the lower side.

[0056] The sliding contacts 14, 14' and the corresponding contacts 13, 13', which are configured to connect with the sliding contact line 100, are also arranged on the upper and lower sides of the replaceable part 4 in the same, however, mirror-symmetrical manner.

[0057] The corresponding connecting contacts 13, 13' and sliding contacts 14, 14' protrude from the corresponding connecting contact openings 15, 15' and sliding contact openings 16, 16' provided in the replaceable component 4, each pressed outward by a clamping member, preferably pressed outward by a spring. As will be further described below, for this purpose... Figure 1a and 1b A double-acting helical spring 24 is provided. This causes the sliding contacts 14, 14' to press against the sliding contact line 100 along the feed direction Z, and causes the connecting contacts 13, 13' to press against the connecting contacts 12, 12' of the base member against the feed direction Z, thus ensuring a reliable and durable electrical connection. Each of the connecting contacts 13, 13' and the sliding contacts 14, 14' can be provided with its own clamping element, particularly a spring, arranged on the replaceable part 4. Alternatively, one or more clamping elements 24, such as springs, can be provided between the connecting contacts 13, 13' and the sliding contacts 14, 14', which cause the connecting contacts 13, 13' and the sliding contacts 14, 14' to press against each other parallel to the feed direction Z.

[0058] In addition, each of the corresponding contacts 13, 13' and sliding contacts 14, 14' has one or more stops that are not visible in the figures. The stops press against the edges of the openings 15, 15' of the corresponding contacts and the openings 16, 16' of the sliding contacts and prevent the corresponding contacts 13, 13' and the sliding contacts 14, 14' from disengaging from the replaceable part 4.

[0059] Furthermore, the base component 2 has a suction port 19 in its end side 2b, which is flush with a corresponding suction port 20 introduced in the replaceable component 4 on its end side 4a. This allows debris entering the replaceable component 4 that connects the corresponding contacts 13, 13' and the sliding contacts 14, 14' to be sucked out from the outside of the base component 2 by means of a suction device (not shown). This prevents debris from interfering with the function of the always outwardly facing corresponding contacts 13, 13' and sliding contacts 14, 14'.

[0060] Because the replaceable part 4 is symmetrically constructed, when the sliding contacts 14 and 14' moving on the sliding contact line 100 are exhausted, maintenance personnel can easily detach the replaceable part 4 from the base part 2 and reinsert it after rotating it 180°. The unused connection contacts 13 and 13' then become sliding contact lines configured to connect with the sliding contact line 100 and remain pressed against the sliding contact line 100 for an extended period until they are exhausted. Only then is it necessary to use a new replaceable part 4 with unused connection contacts 13 and 13' and sliding contacts 14 and 14'. Moreover, due to its simple replaceability, this can be achieved quickly and without significant assembly costs. The option to replace the replaceable part 4 allows for immediate use when a new replaceable part 4 cannot be immediately provided, and in particular, the work can be performed by trained workers without further specialized skills, thereby greatly improving equipment availability. New replaceable parts 4 can then be provided promptly without time pressure.

[0061] To facilitate maintenance personnel in checking the extent of wear of the sliding contacts 14, 14', the replaceable part 4 has two observation ports 21, 21' extending in the feed direction Z and configured as elongated holes on its end side 2a facing the base and its end side 4b, through which wear indicators 22, 22' are visible from the outside. The wear indicators 22, 22' are arranged inside the replaceable part 4 on the sliding contacts 14, 14' or on the bracket accommodating them, and move upwards together with the increasingly worn sliding contacts 14, 14' into the observation ports 19, 19'. If the sliding contacts 14, 14' are completely worn, this is indicated by the wear indicators 22, 22' resting against the ends of the observation ports 21, 21' in the direction toward the sliding contact line 100.

[0062] Corresponding wear indicators 23 and 23' are provided for the corresponding contacts 13 and 13'.

[0063] Because there is no movement between the connecting contacts 12, 12' and the corresponding connecting contacts 13, 13' during operation and therefore no further wear occurs, the exhausted sliding contacts 14, 14' can also be used to ensure the electrical connection. This effectively doubles the lifespan of the replaceable part 4 in the base part 2, so that after the sliding contacts 14, 14' wear down, it is only necessary to flip the replaceable part 4 so that the still-wearing corresponding connecting contacts 13, 13' can be used as the sliding contacts of the conductive sliding contact line profile of the sliding contact line 100.

[0064] Figure 1a and 1b Show Figure 1 The current collector 1 has a cross-section along the pushing direction E and parallel to the side walls 2d and 2e, connecting the corresponding contact 13 and the sliding contact 14. Figure 1a The four replaceable parts were pushed up, while... Figure 1b The replaceable part is in a fully pushed-up and locked, final assembled and operational state. The portion of the locking pin 9 located outside the section and housed in the base part 2, as well as the recessed portion arranged in the end side 2b, are indicated by dashed lines.

[0065] As can be clearly seen, the unused connecting contacts 13 and 14 are pressed along the feed direction Z toward the connecting contact opening 15 and thus the connecting contact 13, or toward the 16 sliding contact opening, and thus against the not-yet-engaged sliding contact line 100 by a pre-tensioning device in the form of a pre-tensioned helical spring 24 acting between them. The pre-tension of the helical spring 24 is chosen such that the connecting contacts 13 and 14 are fully pressed outwards in the uninstalled state of the replaceable part 4, until the respective stops 25 or 26 of the connecting contacts 13 and 14 stop at the inner edge of the connecting contact opening 15 or the 16 sliding contact opening. Figure 1a and 1b This is clearly visible on the sliding contact 14, which is in its fully disengaged position, while the corresponding contact 13, which rests against the connecting contact 12, is already in its in position. During operation, the sliding contact 14 is then placed against the contact point 12, only in its disengaged position. Figure 1b On the sliding contact line 100 marked in the middle and at this time by it Figure 1b The position shown in the figure is pressed downward along the feed direction Z against the helical spring 24.

[0066] The stops 25 and 26 can also be designed in other ways to restrict the connection of the corresponding contact 13 and the sliding contact 14 from being removed from the replaceable part 4 or the housing of the replaceable part.

[0067] Preferably, the current collector 1 may also have a disengagement device that switches the connection contacts 12, 12', 12a, 12a' without voltage when the locking structure is opened. For example, a sensor can be provided in the base member 2 to detect whether the locking protrusion 10 is located in the recessed portion, for example, by inductive or optical detection. If the locking protrusion is detected not to be located in the recessed portion, the electrical connection between the connection contacts 12, 12', 12a, 12a' and the electrical connection lines 3, 3' is disconnected by a switch provided on the base member 2. This advantageously ensures that the vehicle network of the electrical load powered by the current collector 1 is electrically isolated from the current collector 1, thereby avoiding health hazards to operators replacing replaceable parts.

[0068] Instead of Figure 1 The design of the detachable quick-connect unit 5, which serves as a dovetail joint connecting unit between the base component 2 and the replaceable component 4, is shown in the figure. Figure 7 and 8 The alternative quick-connect units 5b and 5c are shown, and their relationship with [other components] will be discussed in the following text. Figures 1 to 3 The difference between the quick-connect unit 5 and the other unit. For the same or corresponding parts, use the same as in... Figures 1 to 3 The same reference numerals are used for the design scheme shown in the figure.

[0069] exist Figure 7 and 8 The embodiment shown has two quick-connect units 5b and 5c extending along the push-in direction E, which are arranged on the opposite sidewalls 4d and 4e of the replaceable part 4.

[0070] In both cases, the connecting section 2a of the base member 2 is provided with opposing sidewalls 2c and 2d extending upward in the feed direction. These two sidewalls are preferably adjacent to the end side 2b of the base member 2 and extend the base member towards the free-push end in the pushing direction E. The sidewalls 2c and 2d have inwardly protruding connecting protrusions 2e and 2f at their upper ends, which form the connecting parts of the quick-connect unit 5b or 5c.

[0071] Here, in Figure 7 In the case of the quick-connect unit 5b shown, each of the sidewalls 4d and 4e of the replaceable part 4 preferably has a protrusion 4f and 4g extending in the pushing direction E, preferably centrally located along the feed direction Z. The upper edge of each of the protrusions abuts against the connecting protrusions 2e and 2f and provides sliding guidance when the replaceable part 4 is pushed into the base part 2. The protrusions 4f and 4g thus form connecting counterparts of the connecting protrusions 2e and 2f, which serve as connecting members. Advantageously, the protrusions 4f and 4g can be equidistant from the upper or lower side of the replaceable part 4, thereby facilitating the flipping of the replaceable part 4 when exchanging the connecting counterparts 13 and 13' and the sliding contacts 14 and 14'.

[0072] exist Figure 8 In the embodiment shown, a guide groove 4h and 4i extending in the pushing direction E are centrally located on the sidewalls 4d and 4e of the replaceable part 4 along the feed direction Z. These guide grooves surround the connecting protrusions 2e and 2f and thus serve as guides. Here, the connecting protrusions 2e and 2f are arranged on the correspondingly lower sidewalls 2c and 2d of the base part 2. The guide grooves 4h and 4i thus form connecting counterparts to the connecting protrusions 2e and 2f, which serve as connecting members.

[0073] If the connecting protrusions 2e and 2f are arranged on the base part 2 with respect to the upper and lower sides of the replaceable part 4 along the feed direction Z, respectively, in the final assembly state of the replaceable part 4, they are higher or lower than the imaginary center lines of the side walls 4d and 4e, then two corresponding guide grooves 4h and 4i can be provided on the side walls 4d and 4e of the replaceable part 4, respectively.

[0074] exist Figure 7 and 8 The design shown has the advantage that, by pressing the corresponding contacts 13, 13' of the replaceable part 4 against the connecting contacts 12, 12' of the base part 2 along the feed direction Z, the guide grooves 4h, 4i or protrusions 4f, 4g of the replaceable part 4 can be pressed against the connecting protrusions 2e, 2f, thereby improving the seating of the replaceable part 4 in the base part 2. Furthermore, this design is located away from the corresponding contacts 13, 13' of the replaceable part 4 and is therefore better protected from contamination by their debris.

[0075] However, the connecting protrusions 2e and 2f are not necessarily arranged on the ends of the sidewalls 2c and 2d, but can also be arranged at another suitable position on the sidewalls 2c and 2d. If necessary, only one of the connecting protrusions 2e and 2f can be provided, while only the sidewall 2c or 2d is provided on the other side as a guide, or even the sidewalls 2c and 2d can be omitted if necessary. If necessary, the connecting protrusions 2e and 2f can also be formed by a rod arranged on the end side 2b of the base member 2 and extending in the pushing direction E, which works in conjunction with the protrusions 4f or 4g or the guide grooves 4h or 4i.

[0076] Instead of Figure 7 The protrusions 4f and 4g in the middle or Figure 8 The guide grooves 4h and 4i in the middle can also be provided with multiple protrusions and / or guide grooves, and the multiple protrusions and / or guide grooves work together with the various connecting protrusions 2e and 2f or other connecting protrusions on the base component 2. Figure 7 and Figure 8 The combination of the two design schemes is also advantageous and feasible.
