Description

The present invention relates to an elongate lamp having a retaining spring via which said retaining spring can be connected to an elongate support rail, and to a luminaire having said support rail and the elongate lamp.Light systems with support rails, and therefore also known as light strip systems, are fundamentally known from the prior art. The light band system ZX2 of the applicant is mentioned here by way of example. Systems of this type generally have a profiled support rail into which elongated lamps designed as light strips can then be inserted and electrically connected. These lamps are generally locked in the support rail by a rotation mechanism.It is now an object of the present invention to provide an elongate lamp and a luminaire equipped therewith, which on the one hand have a simple structure and on the other hand enable simple assembly.This object is achieved by the subject matter of the independent claims. The dependent claims further develop the central idea of the present invention in a particularly advantageous manner.According to a first aspect, the present invention relates to an elongate lamp for connection to an elongate support rail. The lamp has a lamp structure. The lamp structure in turn has an elongate profile carrier extending along a longitudinal axis, having a front side and a rear side. The lamp assembly further includes a lighting means provided on the front side for emitting light forward in a light emitting direction. The lamp furthermore has a retaining spring which is connectable or connected at the rear side via a profile section of the profile carrier to the lamp structure. The retaining spring has a supporting portion and a fastening portion. The support section preferably protrudes on the rear side from the rear side of the profile carrier with coupling sections. The coupling sections are designed in such a way that they can be connected to a support rail or to the support rail in a supporting manner. Connecting sections of the fastening section on the one hand and the profile section on the other hand are preferably designed to be coordinated with one another such that, in the connected state of the lamp structure and the retaining spring, they are in a direct form-fit connection in order to support the lamp structure solely via the form-fit connection when the retaining spring is connected to a or the support rail in a supporting manner via the coupling sections perpendicular to the longitudinal axis-thus connected in a form-fit manner.The lamp according to the invention thus provides a comparatively simple structure in which the element provided for supporting connection to a support rail, namely here a retaining spring, is of comparatively simple design compared to a rotation mechanism. In addition, the retaining spring is accommodated by means of a positive connection, which on the one hand simplifies the fastening thereof and on the other hand requires a significantly reduced number of parts, in particular compared to a variant with a rotary mechanism. Thus, an elongate lamp, which is simple in construction but can be connected efficiently overall and can be mounted easily, can be provided for connection to an elongate carrier rail. It is thus also possible in a simple manner, for example, to equip already known support rail systems with new elongate lamps; for example, in the sense of a retrofitting or refurbishment.The profile section can preferably have two structural sections which are opposite one another with respect to the longitudinal axis and are directed towards one another and which receive the fastening section with the connecting sections therebetween. The profile section can thus be formed in a particularly simple manner. The retaining fields can consequently be inserted (for example inserted or snapped) between the structural sections in order thus to form the positive connection and to provide the retaining spring securely on the profile carrier. The structural sections can be introduced directly during the production of the profile carrier in a simple manner, which also simplifies the production of the profile carrier.The structural sections can preferably be formed as undercut sections when viewed from the rear side perpendicular to the longitudinal axis. Thus, a simple and secure fastening possibility for the fastening section on the side of the profile carrier can be provided. The fastening section can then be inserted or snapped into the profile section, for example.The profile section, preferably its structural sections, can / can preferably extend parallel to the longitudinal axis. On the one hand, a secure fastening of the retaining spring in the direction perpendicular to the longitudinal axis and thus for retaining the weight force can be provided in this way. Furthermore, the retaining spring can thus be provided along the profile carrier preferably at any desired position, as desired. The profile section or the structural sections can also be introduced directly in this way in a particularly simple manner during the production of the profile carrier.The profile carrier can preferably be made of a metal (for example. (Steel) sheet metal or aluminum) or else made of plastic. Conceivable production methods are, for example. Sheet metal forming process of a sheet metal, (aluminium) extrusion process or plastics injection process.The profile carrier can preferably have a base carrier extending parallel to the longitudinal axis. The profile carrier can thus have a section-namely the base carrier-which on the one hand gives the profile carrier dimensional stability and on the other hand can serve for the support or fastening of further components.The base carrier can preferably form at least a part of the front side and / or the rear side of the profile carrier. Thus, a simple structure and a compact construction of the lamp can be achieved.The profile carrier can preferably have two rear walls which extend parallel to and on both sides of the longitudinal axis on the rear side and together with the base carrier delimit a coupling space in which the retaining spring is preferably accommodated at least partially, preferably at least partially, with its fastening section or with the connecting sections. Thus, the rear side of the profile carrier can be formed, for example, in a U-shape. The profile carrier thus receives an overall high dimensional stability. Furthermore, the coupling space described can thus be provided, in which corresponding components can be accommodated in a safe and space-saving manner, such that the lamp as a whole is of a safe and compact design.The rear walls can preferably each have one of the structural sections. Thus, the structure portions can be provided at stable regions. In addition, the profile carrier can be made comparatively compact in this way.The profile support can preferably have two front walls which extend parallel to and on both sides of the longitudinal axis on the front side and which together with the base support delimit a luminaire space in which the lighting means are preferably at least partially accommodated. The profile support can thus preferably have a U-shaped cross section toward the front side. If the profile support has both the front walls and the rear walls, it can preferably have an overall H-shaped cross section. The front walls also give the profile support an overall high dimensional stability. Furthermore, the lamp space makes it possible to accommodate the lighting means therein in a protected manner. The lamp can thus be constructed to be secure and compact overall.The lamp can furthermore preferably have an optical element, such as a lens (for example an elongate lens element or an elongate lens grid). The optical element is provided or arranged downstream of the lighting means in the light emission direction. Thus, the light emitted by the lighting means can be appropriately optically influenced or modified or redirected as required and desired in order to achieve any defined light emission characteristic.The optical element can preferably be fastened to further profile sections of the profile carrier, preferably of the front walls. Thus, the profile carrier can provide a stable receptacle for the optical element, while the profile carrier can be provided in a simple and compact manner overall. The optical element is preferably fastened or provided to the further profile section at least perpendicularly to the longitudinal axis by means of a form fit. The optical element can thus also be securely fastened in a particularly simple manner and without additional components or fastening means.The further profile section preferably has two further structural sections which are opposite one another with respect to the longitudinal axis and are directed towards one another and accommodate the optical element therebetween.The retaining spring can preferably have a base part from which, with respect to the connected state (i.e. when the retaining spring and the profile carrier are in the form-fit connection), the support section protrudes on the rear side and the fastening section protrudes on the front side. Thus, the retaining spring can have a stable structure, the base part thus preferably makes it possible to give the retaining spring a defined dimensional stability, while the functional sections then ultimately protrude from this base part. Thus, the holding spring can be provided compactly and stably as a whole.The retaining spring, preferably the base portion, may preferably have a ground contact point for securing a ground member such as a ground cable. Since the retaining spring is connected on the one hand to the profile carrier and is also intended to be brought with the support section in connection with a support rail, the retaining spring can thus be used in a simple and secure manner in order to provide a grounding connection from the lamp-for example-to a support rail.The positive connection can preferably be designed as a locking connection. The lamp can thus be coupled to a support rail in a particularly simple manner, for example by means of a plug-in movement. This simplifies the assembly of a corresponding lamp.The latching connection can preferably be formed in such a way that it is produced by relative movement of the retaining spring and the profile carrier in the direction perpendicular to the longitudinal axis-and furthermore preferably parallel to the front-rear direction. The elongate lamp can thus be provided aligned relative to a support rail and then only coupled to or into the support rail by a simple (for example translatory) movement perpendicular to the longitudinal axis. Simple and intuitive assembly can thus be achieved.The connecting sections can preferably have at least one first connecting section and one second connecting section, which are arranged opposite and laterally with respect to the longitudinal axis (in the context of the present invention, "lateral" is to be understood as a rule as a direction perpendicular to the front-rear direction and perpendicular to the longitudinal axis (therefore radially)) protruding from one another and away from the longitudinal axis, in order to form the positive connection there with the profile section and preferably with one of the structure sections of the profile section in each case. Since the connecting sections project laterally opposite one another in a protruding manner, they can thus be provided in a simple manner for the corresponding form-fit connection. The connecting sections exposed in this way thus form an effective possibility for the positive connection.The first connecting section can preferably be oriented on one side of the longitudinal axis perpendicular to the longitudinal axis and preferably perpendicular to the front-rear direction (therefore laterally) or extend (preferably laterally outwards). Thus, an effective positive connection with this first of the connecting sections can be achieved.The second connecting section can preferably be oriented on one and preferably the other side of the longitudinal axis either perpendicularly to the longitudinal axis and further preferably perpendicularly to the front-rear direction (therefore laterally) or extend (preferably laterally outwards). Alternatively, the second connecting section can be oriented at an angle to the longitudinal axis; for example, it can be inclined about an inclination axis oriented in the front-honing direction. In the orientation perpendicular to the longitudinal axis, the first of the connecting sections can also particularly effectively form the positive connection. In the case of a preferably angled orientation with respect to the longitudinal axis, the connecting section can be configured to be comparatively long, since it runs transversely with respect to the positive connection, with the result that it can achieve a larger coupling surface overall and therefore an equally secure positive connection. Since the second of the connecting sections is oriented in a correspondingly angled manner, it can also be used in a preferred embodiment to enable a type of snap-fit function by means of a preferably elastic deformation towards the longitudinal axis, so that the positive fit can be achieved by inserting the retaining spring by means of a snap-fit function of one of the connecting sections (here the second connecting section).The lamp can preferably have at least two of the first connecting sections. Thus, the first connecting section can preferably be provided redundantly, which enables a better, more stable and thus secure connection of the retaining spring. The first connecting sections are preferably arranged offset to one another in the direction of the longitudinal axis, so that they can preferably be accommodated, for example, in the same structural section.The lamp can preferably have at least two of the second connecting sections. The second connecting sections can thus also be provided redundantly and thus for a particularly stable and secure connection. The second connecting sections can preferably be arranged offset to one another in the direction of the longitudinal axis, so that they can be accommodated, for example, in the same structural section. If the at least two of the second connecting sections are oriented at an angle to the longitudinal axis, they can preferably be oriented at an angle directed towards one another. In the plan view of the retaining spring, thus in the inserted state viewed in the direction perpendicular to the longitudinal axis or in the front-rear direction, the two of the second connecting sections then preferably run towards one another in a V-shape, for example. Thus, the function of the angled orientation already described above can be provided in a particularly compact manner in redundant production.At least one of the connecting sections, preferably at least the second connecting section, can preferably be designed to be elastically resilient in such a way that, when the fastening section is inserted into the profile carrier on the rear side perpendicular to the longitudinal axis, the retaining spring latches with the connecting sections into the profile section forming the positive connection. This can be made possible, for example, by the material of the retaining spring. It is also conceivable that the shape of the corresponding connecting section or the corresponding connecting sections permits a corresponding elastically resilient deformation in the desired manner. It is also conceivable for the corresponding connecting sections, such as the previously described second of the connecting sections, to be provided oriented in a correspondingly angled manner with respect to the longitudinal axis in order to enable this function in a simple manner. The corresponding connecting sections can preferably extend obliquely toward the front in the sense of a run-on slope in order to easily achieve a latching of the retaining spring and, if appropriate, a corresponding elastic rebound.The fastening portion can preferably have a transverse portion extending transversely to the longitudinal axis. This gives the fastening section preferably a high dimensional stability.The transverse section can preferably extend between the connecting sections arranged on both sides of the longitudinal axis, so that the transverse section is provided compactly on the one hand, while at the same time increased dimensional stability can be achieved.The transverse section can preferably be formed directly integrally with the connecting sections, so that the retaining spring can be provided simply and compactly overall in construction. The connecting sections can also be provided in a particularly stable manner in this way in a simple manner, which enables a particularly secure positive connection.The transverse section can preferably be supported in the form-fit connection on the rear side of the profile carrier, preferably the base carrier. The transverse section can thus support a secure positioning of the retaining spring.The transverse section can preferably have a cutout which is open continuously axially with respect to the longitudinal axis; this is preferably at an end facing away from the base part. It is thus possible that despite the provision of the defined functional sections-in this case in particular the transverse section-any cables of the luminaire guided on the profile carrier can be guided by the retaining spring, so that these can be guided securely on the one hand and compactly on the other hand. Buckling of the cables can also be reliably prevented in this way. If the recess is also provided at an end facing away from the base part, the retaining spring can be used when cables are already laid, so that the recess is positioned over the cables, which in turn allows simple and secure assembly.The transverse portion may preferably extend integrally from the base part. Thus, the retaining spring can be constructed and manufactured simply and stably as a whole.The coupling sections can preferably be arranged on both sides with respect to the longitudinal axis, so that a simple but stable latching or coupling function can be made possible.The support section can preferably have at least one catch which projects on the rear side and has at least one of the coupling sections. Thus, the support portion can easily provide a latching function. The structure of the retaining spring can be kept simple overall, which simplifies its production.The support section can preferably have at least two of the catches, which are arranged on both sides with respect to the longitudinal axis. Thus, an overall stable and secure latching function can be provided.The at least one or two catches can preferably protrude from the rear side from the base part, and the retaining spring can thus be provided in a compact but stable manner overall.The retaining spring, preferably the fastening section, can preferably have a contact section which projects - preferably on the front side or towards the front - in such a way that, when the retaining spring is in a form-fit connection with the profile carrier, it is in direct contact with the profile carrier. The contact section can project here, for example, as a tip or spike. Thus, it can be made possible for the retaining spring to be in secure physical contact with the profile carrier. The contact section can also serve to increase the positional stability. A secure contact between the retaining spring and the profile carrier can also be permanently maintained in this way, so that the retaining spring can also be used, for example, to provide a secure ground connection, as already described.The retaining spring can preferably be formed integrally and further preferably integrally. Thus, the retaining spring can be produced in a simple and cost-effective but reliable manner overall.The retaining spring can preferably be formed from a metal sheet, preferably by a punching-bending process. The retaining spring can thus be provided by a suitable material (for example spring steel). An overall common manufacturing process can also be used for the retaining spring, so that its manufacture can take place overall with simple and known means.The lamp can furthermore have an electrical contact element which is preferably arranged on the rear side; this is preferably flying. Thus, an electrical contacting possibility with the lamp can be provided in order to supply it with current and / or data, for example by electrical connection or contacting on the side of a support rail.The electrical contact element can preferably have electrical contact points which are designed for electrical contacting with electrical conductors, preferably with a through wiring (for example aligned parallel to the longitudinal axis). The electrical contact element can thus be designed, for example, as a contact plug. In this way, the lamp can be electrically connected in a simple manner.The lamp can furthermore have a or the grounding part which electrically connects the electrical contact element to the retaining spring, preferably via the grounding contact point. Thus, the retaining spring can easily serve as a ground contact element. This is preferably achieved via the electrical contact element, so that an overall secure ground connection can be achieved.The lamp can furthermore have a lamp component, such as an electrical and / or electronic component, for operating the lighting means. Thus, the lamp as a whole can be equipped to be largely or completely ready for operation, which facilitates its assembly. Conceivable components include, for example, an LED driver or operating device, other connection terminals and the like.The luminaire component can preferably be arranged on the rear side, preferably on the base carrier and further preferably in the coupling space. Thus, the lamp component can be stored safely. In addition, it can be provided on the base carrier in a particularly stable manner. If it is arranged in the coupling space, it can also be stored safely and compactly.The luminaire component can preferably be electrically connected to the electrical contact element. Thus, the lamp component can be electrically connected easily. If the electrical contact element is grounded via the retaining spring, for example, the luminaire can thus be designed to be particularly secure overall.According to a further aspect, the present invention further relates to a luminaire having an elongate lamp according to the present invention, as has already been described above. The retaining spring is in the form-fit connection with the profile carrier. The luminaire furthermore has an elongate carrier rail extending along an extension axis. The coupling sections can be connected or are connected to coupling profile sections of the support rail in such a way that the lamp can be fastened to the support rail in a supporting manner; this is preferably oriented with its longitudinal axis parallel to the extension axis.Thus, the advantages of the elongated lamp already described above can also be transferred to a corresponding luminaire. Consequently, a corresponding lamp can be fastened in a particularly simple, intuitive and secure manner to a support rail for forming a corresponding luminaire.The coupling profile sections and the coupling sections can preferably be designed in such a way that the lamp can be connected or is connected to the support rail by means of a latching connection; this is preferably done in the sense of a plug connection perpendicular to the axis of extension. The lamp can thus be mounted on the support rail in a particularly simple but secure manner.The support rail preferably has a U-shaped cross section as viewed in the direction of the extension axis, so that the support rail delimits a receiving space. The support rail can thus serve, for example, for accommodating corresponding components or also parts of the elongate lamp, with the result that the latter is provided in a secure and compact manner overall. The U-shaped cross section also allows the support rail to have a particularly high dimensional stability.The receiving space can preferably be covered by the lamp at least in sections from the outside along the extension axis when the lamp is fastened. The receiving space can thus be securely delimited or concealed, so that components located or received therein, such as the luminaire components, the grounding part or the electrical contact element, are securely received or stored, which overall increases the safety of the luminaire for an operator or assembly technician.The receiving space can preferably receive at least the supporting section when the lamp is fastened, preferably, if present, also the electrical contact element, the grounding part and / or the luminaire component, as already described above. The receiving space can thus be used as well as possible, so that an overall compact and easily produced luminaire can be provided.The luminaire can furthermore have electrical conductors or a through wiring which extend or extend parallel to the extension axis-this preferably in the receiving space-in order to be electrically connected to the lighting means for operation thereof. Thus, corresponding possibilities for carrying current and / or data of the luminaire can be provided in a simple and secure manner. The electrical contact element can preferably be used for the electrical connection.Further embodiments and advantages of the present invention will be described below with reference to the figures of the accompanying drawings.

The lamp structure 2 has, on the one hand, an elongate profile carrier 3 which extends along a longitudinal axis X and has a front side F and a rear side R. The profile carrier 3 can be, for example, an aluminum profile; for example, produced in an extrusion process. A profiled support 3 made of a profiled steel sheet is also conceivable. In principle, the profile carrier 3 can be provided from any suitable material (for example also from plastic) and with any suitable structure.The lamp structure 2 furthermore has a lighting means 4, which is provided on the front side F in order to emit light forwards in a light emission direction L, as can be seen in particular from the representations of FIGS. 1 and 2. The lighting means 4 can have, for example, as can be seen from FIGS. 1 and 2, an LED module 40 with an LED circuit board 41 and LEDs 42 arranged thereon.The lamp 1 furthermore has a retaining spring 5, as can be seen from all FIGS. 1-11. The retaining spring 5 can be connected at the rear side R via a profile section 35 of the profile carrier 3 to the lamp structure 2, as is shown in particular in FIGS. 1-6.The retaining spring 5 has a support section 51 and a fastening section 52, as can be seen in particular clearly from FIGS. 2 and 4-10.The support section 51 protrudes on the rear side from the rear side R of the profile carrier 3 with coupling sections 53 which are designed in such a way as to be connected in a supporting manner to a or the support rail 11, as can be seen, for example, from the illustration in FIG. 2. The coupling sections 53 can preferably be arranged on both sides with respect to the longitudinal axis X.As can be seen in particular from FIGS. 1-10, the support cut 51 can have at least one catch 59 which projects on the rear side and has at least one of the coupling sections 53. As shown in the figures, the support cut 51 can have at least two (here exactly two) of the catches 59 which are arranged on both sides with respect to the longitudinal axis X.As can be seen in particular from FIGS. 2 and 4-6, connecting sections 54, 55 of the fastening section 52 on the one hand and the profile section 35 on the other hand are designed to be coordinated with one another in such a way that, in the connected state of the lamp structure 2 (or profile carrier 3) and retaining spring 5, they are in a direct form-fit connection in order to carry the lamp structure 2 solely via the form-fit connection when the retaining spring 5 is connected to a or the support rail 11 in a supporting manner via the coupling sections 53 perpendicularly to the longitudinal axis X-thus connected in a form-fit manner.The profile section 35 preferably has two structural sections 36 which are opposite one another with respect to the longitudinal axis X and are directed towards one another and which receive the fastening section 52 with the connecting sections 54, 55 therebetween. This profile section 35 can be seen particularly clearly in FIGS. 2 and 4-6 and also in FIGS. 1 and 3.The structural sections 36 are preferably formed as undercut sections when viewed from the rear side R perpendicular to the longitudinal axis X, as can be seen, for example, from the representations of FIGS. 2 and 6.The profile section 35 and preferably its structural sections 36 extends / extend parallel to the longitudinal axis X; preferably over the entire profile carrier 3. This can be seen, for example, from the overview of FIGS. 1-6.The profiled support 3 preferably has a base support 30 extending parallel to the longitudinal axis X, as can be seen in particular from FIGS. 1-6. As shown, the base carrier 30 can form at least a part of the front side F and / or the rear side R (both in the representations) of the profile carrier 3.The profile carrier 3 preferably has two rear walls 31 which extend parallel to and on both sides of the longitudinal axis X on the rear side and which, together with the base carrier 30, delimit a coupling space 32 in which here the retaining spring 5 is preferably accommodated at least partially, preferably at least partially, with its fastening portion 52 or with the connecting portions 54, 55. This can be clearly seen, for example, from the representations of FIGS. 1-6.The rear walls 31 each have one of the structural sections 36, as can likewise be seen from the representations of FIGS. 1-6.The profile support 3 has two front walls which extend parallel to and on both sides of the longitudinal axis X on the front side and which, together with the base support 30, delimit a luminaire space 34 in which the lighting means 4 are preferably at least partially accommodated. This can be seen in particular from the representations of FIGS. 1, 2 and 6.The retaining spring 5 preferably has a base part 50, of which, in relation to the connected state (cf. for example. FIGS. 2 and 6 ) show, on the rear side, the support section 51 and, on the front side, the fastening section 52.Referring to FIGS. 1-6, the at least one or two detents 59 protrude rearward from the base portion 50.The positive connection is preferably designed as a locking connection, as can be derived, for example, from FIGS. 2 and 4-6. The latching connection is preferably designed in such a way that it can be produced by relative movement of the retaining spring 5 and the profile carrier 3 in the direction perpendicular to the longitudinal axis X-and preferably parallel to the front-rear direction-as can be derived from FIGS. 2 and 4-6.The connecting sections 54, 55 preferably have at least one first connecting section 54 and one second connecting section 55, which are arranged opposite the longitudinal axis X and laterally (thus also preferably perpendicular to the front-rear direction) from one another and protruding away from the longitudinal axis X in order to form the positive connection there with the profile section 35-further preferably with one of the structural sections 36 of the profile section 35. The connecting sections 54, 55 can be seen in particular from the representations of the retaining spring 5 in FIGS. 7-10. The correspondingly connected state is evident in particular from FIGS. 2 and 4-6.The first connecting section 54 can preferably be oriented on one side of the longitudinal axis X perpendicular to the longitudinal axis X and preferably perpendicular to the front-rear direction, i.e. can therefore extend radially laterally with respect to the longitudinal axis X, as can be seen in particular from the representations of FIGS. 4, 7 and 8.The second connecting section 55 can preferably be oriented either perpendicularly to the longitudinal axis X on one side and more preferably on the other side of the longitudinal axis X or, as shown, be oriented at an angle to the longitudinal axis X, as can be seen, for example, from the representations of FIGS. 8 and 10.The lamp 1 can preferably have at least two of the first connecting sections 54, which are preferably arranged offset with respect to one another in the direction of the longitudinal axis X, as can be seen in particular from FIGS. 4 and 8.The lamp 1 can preferably have at least two of the second connecting sections 55, which are further preferably arranged offset to one another in the direction of the longitudinal axis X, as can be seen from the representations of FIGS. 8, 10 and 11. With reference to the same figures, if the at least two of the second connecting sections 55 are oriented at an angle to the longitudinal axis X, they can preferably be oriented at an angle directed towards one another. It can be seen from FIG. 11 that these then converge in a type of V shape. Thus, when the retaining spring 5 is placed perpendicular to the longitudinal axis X on the rear side of the profile carrier 3 along a front-rear direction, these second connecting portions 55 can easily fulfil a compact latching function. Thus, at least one of the connecting sections 54, 55, here preferably at least the second connecting section 55, can preferably be designed to be elastically resilient in such a way that, when the fastening section 52 is inserted perpendicular to the longitudinal axis X on the rear side into the profile carrier 3, the retaining spring 5 latches with the connecting sections 54, 55 in the profile section 35 forming the positive connection.The fastening section 52 can preferably have a transverse section 57 extending transversely to the longitudinal axis X. This transverse section 57 preferably extends between the connecting sections 54, 55 arranged on both sides of the longitudinal axis X, as can be seen in particular from FIG. 9. The transverse section 57 is preferably formed directly integrally with the connecting sections 54, 55, as can be seen from FIGS. 8, 9 and 11.The transverse section 57 is preferably supported in the form-fit connection on the rear side R of the profile carrier 3; this is preferably supported on the base carrier 30, as can be seen, for example, in the representations of FIGS. 2 and 4-6.The transverse section 57 preferably has a cutout 58 which is open continuously axially with respect to the longitudinal axis X, as can be seen in particular in FIGS. 2 and 4-9. The recess 58 is preferably provided at an end 570 facing away from the base part 50.The transverse section 57 preferably extends integrally from the base part 50, as can be seen, for example, from FIG. 7.The retaining spring 5 and preferably the fastening portion 52 can have a contact portion 500 (cf. for example FIGS. 7-10 ). The contact section 500 preferably protrudes here (preferably on the front side here) in such a way that, when the retaining spring 5 is in a form-fit connection with the profile carrier 3 (cf. for example FIGS. 2 and 4-6 ), it is in direct contact with the profile carrier 3.The retaining spring 5, preferably the base part 50, may preferably have a ground contact point 56 for securing a ground part 8, such as a ground cable. This can be seen particularly clearly in FIGS. 4 and 5.
