Description

The present invention relates to a (multi-pole) connection terminal which can be plugged onto contact pins - for example a circuit board - for electrical contacting.

Connection terminals are basically known from the prior art. These are used for the electrical connection of electrical conductors. The connection terminals can be provided loosely or secured mechanically. In principle, connection terminals are also known which are attached directly to circuit boards in order to simplify the electrical connection of electrical conductors to the circuit board. For this purpose, such connection terminals usually have integrated contact projections, by means of which they are plugged onto circuit boards and then usually permanently soldered to them. In particular, such a soldering process requires appropriate soldering temperatures, which can affect the insulating material housing, which is usually made of plastic, of a connection terminal to be fastened in this way. Such known terminals generally only have a connection option for electrical conductors from one side, so that through-wiring, which is preferred for connection terminals, cannot be implemented or can only be implemented with great effort.

Connection terminals are also known from the prior art, which are used in lamps and are often provided integrated into a lamp body of the lamp; for example clipped into this. These connection terminals are used in particular for looping through through-wiring on the one hand and for optional tapping from the through-wiring on the other hand; for example, to corresponding lighting components, such as a lighting control unit.

It is therefore an object of the present invention to provide a connection terminal and a printed circuit board arrangement equipped therewith, which enable simple and secure electrical contacting of the connection terminal with high flexibility for providing through-wiring.

This task is solved 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 a connection terminal which has at least two contact elements. Each of the contact elements in turn has two electrically connected conductor clamping points, each for electrical connection to an electrical conductor to provide through-wiring via the contact element. Furthermore, the connection terminal has an insulating material housing that accommodates the contact elements (preferably at least partially or completely). For each conductor clamping point, the insulating material housing delimits at least a part of a conductor insertion channel leading from the outside to the respective conductor clamping point. The conductor insertion channels assigned to the same contact element extend along the same extension axis or at least essentially parallel to it, and are directed away from one another. Each of the contact elements has a contact clamping point for receiving a contact pin. The contact clamping points in turn are each electrically connected to the conductor clamping points of the associated contact element; The contact terminal point and the conductor terminal points of the same contact element are therefore electrically connected to one another. The insulating material housing delimits at least a part of the contact insertion channels leading from the outside to the respective contact terminal point. The contact insertion channels each extend along a further extension axis, which is oriented essentially perpendicular to the extension axis of the assigned conductor insertion channels - that is to say the conductor insertion channels assigned to the same contact element.

In the context of the invention, the fact that the conductor insertion channels extend along the same extension axis and are directed away from one another is understood to mean that the conductor insertion channels are aligned coaxially with one another and their accesses from the outside (i.e. the conductor insertion openings) are on opposite sides; i.e. they are open and accessible facing away from each other. In the context of the invention, the fact that the conductor insertion channels extend (essentially) parallel to the same extension axis and are directed away from one another is understood to mean that the conductor insertion channels are radially offset from one another when viewed in the axial direction, but preferably still overlap when viewed in the axial direction, so that their entrances from the outside (i.e. the conductor insertion openings) are on opposite sides; i.e. they are open and accessible facing away from each other. In the context of the invention, “substantially parallel (to the extension axis)” is understood to mean that the extension direction can be inclined with respect to the extension axis by a maximum of approximately 20°, preferably a maximum of approximately 10°; can therefore extend in a cone of 20° or 10° around the extension axis (longitudinal). In the context of the invention, “essentially perpendicular (to the extension axis)” is understood to mean that the further extension axis is relative to a normal on the extension axis by a maximum of approx. 20°, preferably max. approx. 10°, can be inclined; can therefore extend in a cone of 20° or 10° around the normal (longitudinal).

With the connection terminal described above, it is possible in a particularly simple manner to contact the connection terminal with contact pins (for example a circuit board) by simply plugging it on, while at the same time the functionality of the connection terminal for providing through-wiring is retained due to the conductor insertion channels directed away from one another. Since a clamping contact is also provided for receiving a contact pin in the connection terminal, contact pins used for contacting can be previously provided on a corresponding component, such as a printed circuit board, so that any temperatures for fastening the contact pins (for example by soldering) do not affect the connection terminal itself . In addition, a connection terminal that is as flat as possible and therefore compact can be provided.

All contact insertion channels or their further extension axes are preferably aligned parallel to one another. Furthermore, the contact insertion channels are preferably all accessible from the same side of the connection terminal. In addition, the accesses from the outside (i.e. the contact insertion openings) to the contact insertion channels are preferably all in a row next to one another; The contact insertion channels are therefore preferably all arranged next to one another in a row. This makes it possible to have a compact design of the connection terminal, which can also be particularly easily plugged onto contact pins or onto a contact pin strip. In addition, the conductor insertion channels, which are essentially perpendicular to the plug-on direction, are particularly easy to access after plugging, which simplifies the connection of through-wiring.

The contact elements preferably each have a contact frame and a spring clamping element for each assigned conductor clamping point, which work together to form the respective conductor clamping points. This configuration provides a simple and effective contact option for secure contacting of an electrical conductor. In addition, these components can be manufactured in a particularly simple manner; for example as stamped and bent parts.

Each of the spring clamping elements preferably has a spring clamping leg which is movable - particularly preferably pivotable - provided in order to selectively open the respective conductor clamping point for inserting or removing an electrical conductor. By providing a corresponding spring clamp leg, a simple structure of the spring clamp element with an effective clamping effect can be provided. In addition, such a spring clamping element can be produced in a particularly simple manner; for example as a stamped and bent part.

Each of the spring clamping elements or preferably their spring clamping legs can/can preferably be biased towards the associated contact frame (i.e. the contact frame of the same contact element). In this way, an effective clamping effect can be permanently maintained.

The spring clamping elements of the same contact element can preferably be formed integrally with one another. This means that, on the one hand, the number of individual parts can be reduced and, on the other hand, production and assembly can be simplified.

For example, the spring clamping elements of the same contact element can be formed via a connecting web, which particularly preferably extends essentially parallel to the axis of extension of the conductor insertion channels assigned to the same contact element between the spring clamping elements. A simple and effective design of the integrally provided spring clamping elements can thus be made possible. In addition, on the one hand, the spring clamping elements can be manufactured in a way that protects the material, while on the other hand, a simple and defined assembly and, preferably, automatic positioning of the two spring clamping elements is made possible.

The contact elements can preferably each have a contact clamping spring, which interacts with the associated contact frame in order to form the respective contact clamping point. The contact element can therefore also provide an effective clamping point due to its simple but effective structure. The contact clamping springs are preferably biased towards the associated contact frame in order to permanently enable an effective clamping effect of the contact clamping point.

The contact clamping springs are particularly preferably formed integrally with at least one or both of the associated spring clamping elements (i.e. the same contact element). In this way, the structure of the connection terminal as well as its production and assembly can be further simplified overall.

The contact clamping springs are preferably each formed in the associated connecting web (i.e. the same contact element), so that these can be provided in a simple and effective manner.

The contact clamping points can each be provided between the assigned conductor clamping points with respect to a direction parallel to the extension axis of the assigned conductor insertion channels - that is to say the conductor insertion channels assigned to the same contact element. In this way, the respective contact element with the contact terminal point - and thus the connection terminal as a whole - can be made compact, while at the same time their function of providing through-wiring can be effectively maintained.

The contact insertion channels are preferably each viewed from the outside towards the associated contact clamping point along their extension axis at least in sections on one side of a first contact guide section of the associated contact frame and at least in sections on a side opposite the one side by a second contact guide section of the associated contact frame. In this way, a contact pin to be inserted can be safely received and stored in the corresponding contact insertion channel in order to be able to effectively and safely provide electrical contact with the associated contact element.

The first contact guiding section and the second contact guiding section are preferably arranged downstream of one another along the extension axis of the associated contact insertion channel - therefore in its axial direction. The contact insertion channel can thus be provided safely and stably, while electrical contacting is effectively enabled.

The first contact guiding section and the second contact guiding section are preferably connected to one another via a bending section of the associated contact frame. The bending section can be a section of the associated contact frame that extends, for example, transversely or orthogonally to the extension axis of the contact insertion channel. In this way, the contact guide sections can be provided simply by bending and thus be provided with overall stability at the same time. Overall, the part of the contact insertion channel provided by the contact frame can also be produced in a simple manner by a punching-bending process for producing the contact frame.

The bending section preferably has a passage opening which forms or delimits part of the associated contact insertion channel. Thus, on the one hand, the contact insertion channel can be provided effectively, while on the other hand, the contact frame retains a high level of stability despite providing a corresponding feed-through option for a contact pin. Likewise, the previously described first and second contact guide sections can be provided in a particularly simple manner in this way.

The contact elements can preferably each have further conductor clamping points in addition to the conductor clamping points to provide the through-wiring. In this way, the functionality of the connection terminal can be expanded in any way.

The conductor clamping points and the further conductor clamping points of the same contact element are preferably formed integrally with one another. In this way, the advantages of an integral design, such as the reduction of individual parts and the simplification of production and assembly, can also be transferred to the other conductor terminal points in the same way.

Preferably, one of the conductor clamping points shares a spring clamping element with one of the further conductor clamping points of the same contact element. This then has a spring clamp leg that can be moved or pivoted for each assigned conductor clamping point for selectively opening the respective conductor clamping point. This means that an overall compact connection terminal with a small number of parts and therefore simple assembly and manufacture can be provided.

For each further conductor clamping point, the insulating material housing preferably delimits at least a part of a further conductor insertion channel leading from the outside to the further conductor clamping point. These further conductor insertion channels can basically be designed comparable to the conductor insertion channels described above. In particular, the further conductor insertion channels preferably also each extend along a further extension axis, which is or are preferably oriented substantially parallel to the extension axis of the conductor insertion channels assigned to the same contact element. An overall compact design of the connection terminal can thus be provided while providing several corresponding conductor terminal points. Due to the preferred parallel arrangement of the extension axes of the conductor insertion channels, in addition to a compact design of the connection terminal, electrical contacting can also be easily implemented by an operator.

For each contact element, the connection terminal can be used for at least one or both conductor clamping points and, if present, preferably also for at least one or more or all others Conductor clamping points (preferably each) have an actuating element, such as a pusher or a lever, for selectively opening the respective conductor clamping point for inserting or removing an electrical conductor. In this way, the functionality of the connection terminal can be further increased. In particular, different electrical conductors, such as rigid or flexible conductors, can be easily connected and removed again if necessary.

The respective actuating element can preferably be movably accommodated in the insulating material housing. This means that the actuating element can be stored easily and safely with a compact design of the connecting terminal, which in turn enables a high level of functionality and easy operation.

The at least two (or more) contact elements can preferably be arranged next to one another in a row; this is particularly preferably offset perpendicular to the conductor insertion channels and the contact insertion channel or to their extension axes. This means that any multi-pole connection terminal can be provided in a simple and compact manner.

By providing only one insulating material housing, the production of the same can be simplified and assembly can also be made easier. In principle, it is conceivable that the insulating material housing is designed in several parts. For example, the insulating material housing can have a housing part and a housing cover, which can be closed after receiving the corresponding contact elements in order to securely accommodate the contact elements therein. In principle, it is also conceivable that the insulating material housing is designed in several parts in such a way that, for example, a separate insulating material housing part is provided for each contact element, which can then be connected in a row in any number - for example to form a multi-pole connection terminal; for example via snap or snap connections.

The connection terminal or its insulating material housing preferably has positioning elements for positioning the connection terminal on a circuit board. The connection terminal can therefore have a defined positioning structure in order to be positioned securely and in a defined alignment at the assembly area. In addition, defined positioning points can be provided in order to avoid a large surface area of the connection terminal - for example on a circuit board. For example, electrical structures on a circuit board can be protected. The connection terminal on the one hand and the circuit board on the other hand can also be provided at least partially thermally separated from one another.

The positioning elements preferably protrude outwards, with preferably distal ends of the positioning elements all lying in one plane. Simple structural means can therefore be used to provide a secure and defined support option for the connecting terminal.

The connection terminal or its insulating material housing preferably has a coupling element for mechanically coupling the connection terminal. This coupling element can be designed, for example, as a latching or snap connection component (e.g. as a latching pin), which interacts with a corresponding latching or snap connection component (e.g. a latching receptacle) on the assembly side (e.g. a circuit board) for mechanical coupling. The coupling element can preferably be formed integrally with at least one of the positioning elements.

The connection terminal or its insulating material housing preferably has a receiving section for partially receiving the contact pins to be electrically connected via the contact terminal points, with the contact insertion channels preferably each opening into the receiving section. In this way, defined structures of a contact pin structure, such as a support part of a contact pin header, can be safely accommodated, while at the same time the connection terminal can be mounted safely and as compactly as possible.

In a particularly preferred embodiment, the receiving section can have at least one of the positioning elements or the positioning sections can form the receiving section. These two functional sections can therefore be provided in an integrated manner, so that a high level of functionality is possible at the same time with a compact design of the connecting terminal.

According to a further aspect, the present invention further relates to a circuit board arrangement which, in addition to the above-described connection terminal, also has a circuit board with contact pins projecting therefrom. The connection terminal is then arranged on the circuit board in such a way that the contact pins are each connected to the associated contact terminal point via (exactly) one (other) of the contact insertion channels, so that the two conductor terminal points and, if present, preferably also the further conductor terminal points of the associated contact element with the Circuit board are electrically connected.

Due to the above-described circuit board arrangement, the advantages of the connection terminal can be equally transferred to a corresponding circuit board arrangement. The circuit board can thus be easily equipped with appropriate contact pins. The connection terminal can then be electrically contacted by simply plugging it on in a particularly simple and gentle manner for the connection terminal. The connection terminal is therefore also independent of any fastening processes - for example soldering - of the contact pins.

The contact pins are preferably each detachably connected to the associated contact terminal point, so that the connection terminal can be removed or replaced as required.

At least several or all of the contact pins can preferably be connected in a contact pin strip by means of a carrier part, so that the provision of corresponding contact pins on the circuit board is simplified. The carrier part is preferably accommodated in the receiving section. The carrier part can preferably be a plastic part, so that the contact pins are provided in a simple manner isolated from one another, while at the same time they are easy to handle and are also positioned relative to one another in a correspondingly automatically defined manner.

According to a further aspect, the present invention further relates to a lamp which has a lamp body with lamp(s) and a circuit board arrangement according to the present invention, which in turn are electrically coupled to one another in order to functionally couple the lamp body and preferably the lamp to the circuit board .

In this way, the advantages of the connection terminal and the circuit board arrangement are equally transferred to a luminaire equipped with it.

The figures show an exemplary embodiment of a connection terminal 1 according to the present invention. Such connection terminals 1 are used in particular to connect an electrical or electronic device (e.g. a corresponding lamp) to an externally provided wiring and to tap this external wiring for defined electrical or electronic components, such as (via) a circuit board 10 and/or a Operating device.

The connection terminal 1 has at least two or more (here five) contact elements 2. Depending on the desired number of poles, the number of contact elements can be chosen arbitrarily; for example 3-pin, 5-pin (as shown), 7-pin or 11-pin and the like. Each of the contact elements 2 has two electrically connected conductor clamping points 20, each for electrical connection to an electrical conductor to provide through-wiring via the contact element 2. This is particularly preferred from the 4 visible.

The contact elements 2 preferably each have a contact frame 21 and a spring clamping element 22 for each assigned conductor clamping point 20, as does this 4 can be seen. The contact frame 21 and the corresponding spring clamping elements 22 of the same contact element 2 work together in such a way that they form the respective conductor clamping points 20.

Each of the spring clamping elements 22 has, as in 4 can be seen, preferably at least one spring clamp leg 23, which is movable and here preferably pivotable in order to selectively open the respective conductor clamping point 20 for inserting or removing an electrical conductor.

Each of the spring clamping elements 22 or their spring clamping legs 23 is/are preferably biased towards the associated contact frame 21. In the 4 The associated spring clamp legs 23 are therefore biased upwards against the contact frame 21 with respect to the two conductor clamping points 20 of the contact element 2 visible in the section shown.

The spring clamping elements 22 of the same contact element 2 are preferably formed integrally with one another, as is the case 4 can be seen. The spring clamping elements 22 of the the same contact element 2, for example via one here 4 essentially horizontally extending connecting web 24 of the same contact element 2 or be formed integrally with one another via this.

The contact elements 2 or their components - i.e. the contact frame 21 and the spring clamp element(s) 22 - are preferably manufactured as stamped and bent parts.

The connection terminal 1 further has an insulating material housing 3 which at least partially or - as shown here by way of example - preferably completely accommodates the contact elements 2. The insulating material housing 3 is preferably made of a plastic material. The insulating material housing 3 is preferably manufactured as an injection molded part. The insulating material housing 3 can be provided in any number of parts and, for example, as shown, have a housing part 30 and a housing cover 31, which are closed after receiving the corresponding contact element 2.

For each conductor clamping point 20, the insulating material housing 3 delimits at least a part of a conductor insertion channel 4 leading from the outside to the respective conductor clamping point 20, such as those in the 3 and 4 are shown.

The conductor insertion channels 4 assigned to the same contact element 2 can extend along the same extension axis X1 and be directed away from one another, as is the case in particular 4 can be removed in order to be accessible on opposite sides of the connection terminal 1; The accesses or conductor insertion openings 41 of the conductor insertion channels 4 are therefore open and directed away from one another. According to this exemplary embodiment, the conductor insertion channels 4 assigned to the same contact element 2 are therefore arranged coaxially with one another and directed away from one another.

It is also conceivable that the conductor insertion channels 4 assigned to the same contact element 2 extend essentially parallel to the same extension axis X1 and are directed away from one another in order to be correspondingly accessible on opposite sides of the connection terminal 1; therefore also in such a way that the accesses or conductor insertion openings 41 of the conductor insertion channels 4 are open and directed away from one another.

Like that too 4 As can be seen, the optional connecting web 24 can preferably extend between the spring clamping elements 22 essentially parallel to the extension axis X1 of the conductor insertion channels 4 assigned to the same contact element 2.

Each of the contact elements 2 also has a contact clamping point 5 for receiving a contact pin 11, such as this in particular 4 and 5 can be seen.

The contact clamping points 5 are each electrically connected to the conductor clamping points 20 of the same contact element 2. This can be made possible, for example, by the contact clamping point 5 and the conductor clamping points 20 of the same contact element 2 being formed integrally with one another. In principle, the contact clamping point 5 on the one hand and the conductor clamping points 20 of the same contact element 2 on the other hand can also be electrically contacted with one another in another way.

Like this in particular 4 and 5 As can be seen, each of the contact elements 2 can have a contact clamping spring 50, which cooperates with the associated contact frame 21 in order to form the respective contact clamping point 5. The contact clamping springs 50 are preferably biased towards the associated contact frame 21, as shown for example in FIG 5 is visible.

The contact clamping springs 50 can each preferably be formed integrally with at least one or both of the associated spring clamping elements 22. How out 4 As can be seen, the respective contact clamping spring 50 can preferably be formed in the associated connecting web 24.

The contact clamping points 5 can each preferably be provided with respect to a direction parallel to the extension axis X1 of the conductor insertion channels 4 assigned to the same contact element 2 between the assigned conductor clamping points 20, as exemplified in FIG 4 is visible.

As exemplified in 5 can be seen, the insulating material housing 3 delimits each contact terminal point 5 at least a part of the contact insertion channels 6 leading from the outside to the respective contact terminal points 5. The contact insertion channels 6 each extend along a further extension axis X2, which is essentially perpendicular to the extension axis X1 of the same contact element 2 assigned conductor insertion channels 4 is oriented, as exemplified in the 1 , 4 and 5 is visible.

The further extension axes X2 of the contact insertion channels 6 are preferably all aligned parallel to one another, as is the case for example 5 can be seen. The contact insertion channels 6 can preferably all be accessible from the same side of the connection terminal 1 (in the figure). The exemplary embodiment shown is an underside of the connection terminal 1). The contact insertion channels 6 are preferably all arranged in a row next to one another, as is also clearly shown in the example 5 can be seen. In 5 It can also be seen that the accesses from the outside (i.e. the contact insertion openings 63) to the contact insertion channels 6 are preferably all arranged next to one another in a row.

Like in particular from the 5 As can be seen, the contact insertion channels 6 can each be seen from the outside towards the associated contact clamping point 5 along their extension axis of the associated contact frame 21 be limited.

The first contact guide section 61 and the second contact guide section 62 are preferably arranged downstream of one another along the extension axis X2 of the associated contact insertion channel 6, as in particular 5 can be seen.

The first contact guiding section 61 and the second contact guiding section 62 are preferably connected to one another via a bending section 25 of the associated contact frame 21, as can be seen from the synopsis of 4 and 5 is visible. The bending section 25 preferably has a passage opening 60, which forms part of the associated contact insertion channel 6 (cf. 5 ).

The contact element 2 preferably each have, in addition to the assigned conductor clamping points 20 for providing the through-wiring, further conductor clamping points 26, as shown in FIG 4 is shown as an example. In the exemplary embodiment shown, two further conductor clamping points 26 are shown here as an example for each contact element 2.

Like that too 4 As can be seen, the conductor clamping points 20 and the further conductor clamping points 26 of the same contact element 2 can preferably be formed integrally with one another.

For example, it is conceivable that one of the conductor clamping points 20 shares a spring clamping element 22 with one of the further conductor clamping points 26 of the same contact element 2, which for each assigned conductor clamping point 20, 26 has a spring clamp leg 23 that can be pivoted for selectively opening the respective conductor clamping point 20, 26. So divide, looking at that in the section view of the 4 Contact element 2 shown here, for example the conductor clamping point 20 shown here on the left, a spring clamping element 22 with a further conductor clamping point 26 underneath. Likewise, the conductor clamping point 20 shown here on the right shares a spring clamping element 22 with a further conductor clamping point 26 underneath.

As shown here, the spring clamping elements 22 have the corresponding spring clamping leg 23 for each conductor clamping point 20, 26, which, in the case of an integral design, are connected to one another via an arcuate connecting section 27 of the spring clamping element 22 and are preferably movable or pivotable via this same.

The insulating material housing 3 preferably delimits each further conductor clamping point 26 at least a part of a further conductor insertion channel 40 leading from the outside to the further conductor clamping point 26. The further conductor insertion channels 40 preferably each extend along a further extension axis X3, which is essentially parallel to the extension axis X1 of the conductor insertion channels 4 assigned to the same contact element 2 are oriented, such as 4 can be seen. The further conductor insertion channels 40 are accessible from the outside via corresponding further conductor insertion openings 42. In the exemplary embodiment shown, two further conductor clamping points 26, each with an assigned conductor insertion channel 40, are shown here as an example. The two further conductor insertion channels 40 here, for example, each run parallel to one of the conductor channels 4. The further conductor insertion openings 42 of these further conductor insertion channels 40 are also open and directed away from one another, and are preferably located next to the conductor insertion opening 41 of the adjacent conductor insertion channel 4.

The connection terminal 1 can be as follows 2-5 As can be seen, each contact element 2 for at least one or both conductor clamping points 20 preferably has an actuating element 7, such as here for example a pusher or alternatively a lever, for selectively opening the respective conductor clamping point 20 for inserting or removing an electrical conductor. In principle, it is conceivable that, alternatively and additionally, at least one, several or all of the further conductor clamping points 26 per contact element 2 have a corresponding actuating element 7 (not shown). The respective actuating element 7 is like that 4 can be seen, preferably movably accommodated by the insulating material housing 3.

Like this in particular 5 As can be seen, the plurality of contact elements 2 can be arranged in a row next to one another; this is particularly preferably offset perpendicular to the conductor insertion channels 4 and the contact insertion channel 6 or to their extension axes X1, X2.

The connection terminal 1 or its insulating material housing 3 can preferably have positioning elements 8 for positioning the connection terminal 1 on a circuit board 10, such as this in particular 1 and 3-5 can be seen. The positioning elements 8 preferably protrude outwards. In the exemplary embodiment shown here, the positioning elements 8 are designed, for example, as webs. However, they can be designed in any other shape, such as a pin or frame. Particularly preferably, distal ends 80 of the positioning elements 8 all lie in a plane E, such as that shown in FIG 1 and 4 is visible.

The connection terminal 1 or its insulating material housing 3 preferably has a receiving section 9 for partially receiving the contact pins 11 to be electrically connected via the contact terminal points 5, the contact insertion channels 6 each preferably opening into the receiving section 9, as is the case in particular 5 can be seen.

As is also exemplary 1 and 3-5 As can be seen, the receiving section 9 can preferably have at least one of the positioning elements 8.

The figures also show a circuit board arrangement 100 equipped with the connection terminal 1. In addition to the connection terminal 1, this also has a circuit board 10 with - here five - contact pins 11 protruding from it. The connection terminal 1 is arranged on the circuit board 10 in such a way - preferably positioned via the positioning elements 8 - so that the contact pins 11 are each connected to the associated contact clamping point 5 via one of the corresponding contact insertion channels 6, so that the conductor clamping points 20 of the associated contact element 2 are connected to the circuit board 10 are electrically connected. As already described, the circuit board 10 according to the exemplary embodiment shown has several - here five - contact pins 11, which are then preferably each assigned to (exactly) one (other) of the contact clamping points 5, as shown in particular in the sectional view 5 can be seen.

The contact pins 11 are each preferably detachably connected to the associated contact clamping point 5.

Like that too 5 As can be seen, several (as shown here, the two left and the two right as a pair) or all of the contact pins 11 can be connected in a contact pin strip 13 by means of a carrier part 12. If necessary, standard components can be preferred. The carrier part 12 can, for example, 1 , 4 and 5 can be seen, be included in the receiving section 9.

The circuit board arrangement 100 described in this way and shown as an example can also be part of a lamp according to the invention, which, in addition to the circuit board arrangement 100, also has a lamp body with lamp(s), all of which are electrically coupled to one another in such a way that the lamp body and preferably its lamps are functional with the circuit board to pair.
