Field of the invention

The invention relates to an arrangement of a

Terminal block and attached by means of a component carrier to the terminal external electrical

Component as well as the component carrier in the form of a

Aufrastaufsatzes or a plug-in metal part.

Background of the invention

Terminal blocks, which are typically arranged side by side on a support rail, e.g. a so-called DIN rail can be latched, contain a plurality of

Wire end connection terminals for connecting the wire ends of electrical cables. A terminal block has

Terminal block housing made of fireproof plastic, in which from an upper narrow side ago

Conductor insertion channels run into the interior of the terminal block housing, which lead to wire end connection terminals (see.

Catalog No. 3 "Terminal Blocks", Version 2013/2014 by

Phoenix Contact, www.phoenixcontact.com). A terminal may also have other contact possibilities, e.g. Bridge shafts for inserting contact bridges for

Making bridges between adjacent ones

Terminal blocks (see Catalog No. 3 "Terminal Blocks", Version 2013/2014 from Phoenix Contact, for example page 103,

www.phoenixcontact.com).

Some terminal blocks also have so-called

multifunctional separation zones (see Catalog No. 3 "Terminal blocks", version 2013/2014 from Phoenix Contact, series terminal blocks of the "...- TG" series, eg page 470,

www.phoenixcontact.com). Referring to Fig. 12, it is known to use electrical components, e.g. a resistor 2 in a component connector 3 with a separate

Insert plastic housing 4 and then use this in the multi-functional separation zone of this special terminal blocks (see Fig. 12 and Catalog No. 3

"Terminal blocks", version 2013/2014 from Phoenix Contact, component plug "P-CO ...", e.g. Page 481,

www.phoenixcontact.com). This component connector 3 has inside the KunstStoffgehäuses 4 two tension spring terminals 5, by means of which the resistor 2 is contacted. The tension spring terminals 5 are in electrical connection with contact plates 6 at the lower end of the component plug 3, wherein the contact plates 6 are contacted in the so-called universal separation zone.

This component connector 3 with a separate

Although plastic housing 4 have proven to be excellent, however, come in terms of the size of the usable therein electrical components to limits.

Furthermore, the electrical components on at least three sides, namely below (direction terminal), and with side walls 7 on the two lateral sides of the

housed separate plastic housing 4, which is the

Reduced heat dissipation. In Fig. 12, only the rear side wall 7 is shown and the front side wall in operation is removed for ease of illustration, i. the plastic housing 4 is not so opened

Operating condition. In addition, the maximum size of the usable electrical components by the separate

Plastic housing, which in turn certain

Dimensions must comply, limited.

Furthermore, it has been shown that the maximum weight of the usable electrical components is limited to a fatigue of the electrical contact between the

Contact plates 6 and the cooperating contact terminals in the terminal block (not shown in Fig. 12) to

avoid. In particular, it has shown that this

Use of terminal blocks in vibration-prone ones

Environment is of particular importance.

Incidentally, the component plug 3 with the

separate KunstStoffgehäuse 4 is a further improvement in terms of its complexity solution. General description of the invention

The object of the invention is therefore to provide a component carrier which is suitable for carrying large, heavy and high power-consuming electrical components, e.g. To attach high-power diodes to a terminal block and connect electrically.

Another aspect of the job is one

Component carrier to provide, by means of which large, heavy and high power dissipation electrical components, e.g. High performance diodes

vibration-resistant to be attached to a terminal block can and wherein a good heat dissipation is ensured by the electrical component.

Another aspect of the job is one

Component support to provide, by means of which large electrical components vibration resistant to a

Terminal block can be attached, with the

Operability of the wire end terminals of the terminal block is affected as little as possible.

The object of the invention is solved by the subject matter of the independent claims. Advantageous developments of the invention are defined in the subclaims.

According to the invention, an arrangement of a terminal and a discrete external electrical or

electronic component provided. The arrangement comprises at least one terminal with an insulating terminal block housing and terminals. In this case, a plurality of terminal blocks next to each other on a

Retaining rail, e.g. a so-called top hat rail are snapped. The terminals are of the

Terminal box housed and include at least two wire end connection terminals, which are adapted to and normally used to wire ends of

To join cable ladders. There are a variety of connection techniques for connecting wire ends, with the present invention in particular terminal blocks with spring terminals come into consideration. Particularly relevant for this purpose are push-in terminals (so-called

Direct plug-in technology, cf. Catalog No. 3 "Terminal Blocks", Version 2013/2014 from Phoenix Contact, Push-in Connection terminals PT, eg page 101 ff.,

www.phoenixcontact.com), as tension spring clamp (see Catalog No. 3 "Terminal Blocks", Version 2013/2014 by Phoenix

Contact, Tension clamp terminals ST, e.g. Page 201 ff., Www.phoenixcontact.com) and quick-release terminals with cutting contact, cf. Catalog No. 3 "Terminal Blocks", Version 2013/2014 from Phoenix Contact, quick-connect terminals QT, for example, page 305 ff., Www.phoenixcontact.com)

Spring clamps are prepared and will

Normally used wire ends of electrical cables from the outside through each one conductor insertion channel into the associated wire end terminal

introduce and by means of the respective

Terminal end terminal to be clamped, electrically closed

contact and thus electrically connect to the terminal block.

The arrangement further comprises a discrete external electrical device with its own

Component housing and a first and second

electrical connection. It is thus in particular an electrical component with a two-pole

Component housing.

Further, a component carrier is included, by means of which the electrical component on a narrow side of the

Terminal block is mechanically fastened, and indeed

in particular on that narrow side at which the insertion channels for the wire ends are located. This narrow side is referred to herein as the upper narrow side. The first electrical connection comprises a first

Lead wire of the electrical component, which extends out of the component housing out. The second electrical connection may be configured according to the following two embodiments of the invention: i) Either the second electrical connection also comprises a second connection wire. Then, the first and second connection wire, so both leads of the electrical component, pluggable formed for the spring-Aderendanschlussklemmen the terminal block and are directly in the first and second

Aderendanschlussklemme the terminal plug inserted and contacted there electrically, or ii) the component carrier itself is electrically conductive and the second electrical connection of the electrical component is directly electrically and mechanically connected to the component carrier. Then the first connection wire can be plugged in for the

Aderendanschlussklemmen the terminal block is formed and is inserted directly into the first spring-Aderendanschlussklemme the terminal and contacted there electrically, and the component carrier itself is pluggable formed for one of the terminals of the terminal and is directly in one of

Terminal blocks of the terminal block inserted and there

electrically contacted.

In the variant ii) of the component carrier is made of metal and thus electrically conductive, since it performs a dual function, namely on the one hand, the electrical Mechanically fasten the component on the terminal block and on the other hand to form part of the electrical connection of the electrical component. In the

Variant i), the component carrier itself does not need to be electrically conductive and is preferably made of plastic, e.g. made of polyamide 6.6, which

fire protection technology is advantageous.

Accordingly, the electrical component either with its own two leads (variant i)) or with its own lead wire on the one hand and the plug-in electrically conductive component carrier on the other hand plugged directly into the terminals of the terminal and contacted there. This saves in

Advantageously, an additional component plug, with its own plastic housing, in which the electrical component, largely enclosed by plastic cloth walls, is used, e.g. as with the

Component plug type P-CO ..., as in the

Description of the description is described.

This leaves more room for the electrical component

Without blocking or disturbing the access to the terminals of the terminal block.

Furthermore, the heat of the electrical component can be better delivered directly to the ambient air, which the

Heat dissipation improved.

In addition, not only is there basically more space available for the electrical component, but the same component carrier can be largely independent of the size be used of the electrical component, so that the size of the usable electrical components is variable to a greater extent, as they are not by the largely

closed plastic material housing of the additional

Component plug is limited.

Another advantage is that electrical components can also be connected to such terminal blocks, which were previously not intended for this purpose. Namely, the invention allows the connection of electrical

Components even on terminal blocks, the no

multifunctional separation zone, e.g. of the series "...- TG" from Phoenix Contact (see Catalog No. 3 "Terminal Blocks", version 2013/2014 of Phoenix Contact, series terminals of the series "...- TG", eg page 470, www. phoenixcontact.com) Furthermore, it has been shown that the direct

Inserting the electrical components, possibly with a metallic component carrier, which also acts as a plug-in connection element, is suitable for attaching relatively heavy electrical components to the terminal block. A fatigue of the electrical contact between the contact plates and the cooperating

Contact terminals in the multifunctional separation zone can be avoided, which is particularly advantageous when using the terminal blocks in a vibration-prone environment.

The invention therefore represents a very simple but at the same time advantageous in many respects solution, if an assembly, which only from the electrical component, the terminals of the electrical component, possibly with connecting wires and the simple

Component carrier, possibly with fasteners such as For example, a fastening nut is made, and the one or more connecting wires of the electrical component are inserted directly into the originally prepared for connecting wire ends of cable ladders and provided wire end terminals.

The invention is particularly for connection to the

Terminal block and provided for mounting on the terminal of a diode or a resistor and suitable. Here come with appropriate weight, appropriate size and power dissipation of the diode or the resistance, the benefits particularly bear.

It has been shown that eg with a power diode with a direct current of IFAV> 2.5 A at sin. 180 and a temperature of T _a = 45 ° C, the operating temperature compared to the use of the component connector type P-CO ...

significantly reduced and kept within acceptable limits. This is e.g. on the use of

Rectifier diodes of type SKN 2.5 and SKN 5 from Semikron (see www.semikron.com).

The electrical component is therefore in particular free and without the component housing in a to the

Component housing additional separate in the

Terminal block pluggable KunstStoffgehäuse is located above the upper narrow side of the terminal block housing, in which the Leitereinführkanäle are when the electrical component by means of the component carrier on the upper narrow side of the terminal mechanically

is attached so that the component housing is exposed laterally and heat to the outside free from walls of a additional separate pluggable in the terminal block

KunstStoffgehäuse can deliver directly to the ambient air. In a component housing of axial design so in particular the radial annular wall of the

Component housing free.

Thus, the heat can be better released to the ambient air and the lateral extent is opposite to the

Use of the P-CO type component plug ...

reduced, which is advantageous in terminal blocks, since they are arranged in large quantities close together.

Furthermore, the function of integral cooling fins of the diodes, e.g. Semikron's SKN 5 type is more effective.

The electrical component is preferably of axial design. Sometimes, referred to the component housing of an axial housing, which is generally cylindrical and has a first and second end face, which are axially opposite each other. In these types of component housings of electrical

Devices such as e.g. Diode or resistors, the electrical connections are typically at the axial

End faces arranged and opposite, i.

in each case an electrical connection to each one of the first and second end faces. For the present

In particular, electrical components are contemplated in the invention, in which the first electrical connection is formed as a first connection wire, which axially from the first end side of the component housing

protrudes. The second electrical connection of the

electrical component, however, is preferably as Fixing bolts, in particular threaded bolt formed which axially from the second end face of the

Component housing protrudes. Preferably, the electrical component by means of this fastening bolt or threaded bolt and a complementary

Fixing element, in particular a corresponding fastening nut fixed to the component carrier

connected or screwed and can be placed as a unit on the terminal block and in the terminals

be inserted, which ensures a simple and safe installation despite the very simple structure.

In a particular design, the second lead wire extends axially from the mounting bolt or

Threaded bolt of the electrical component or out of the corresponding mounting nut, so in turn at both axial end faces of the

Component housing each a connecting wire of the

electrical component for insertion in two

Wire end connection terminals are available.

Accordingly, in a preferred embodiment, the first and second leads jump axially in opposite directions

Directions from the electrical component, and are angled substantially at right angles in the same direction. The angled free ends of the first and second

Terminal wire then extend in the same direction transverse to the axial design of the electrical component, so that the two angled free ends and the

Component housing by and large form a U-shape. This has the advantage that the distance between the angled free ends of the first and second Connecting wire free to the distance between the

associated wire end terminals can be adapted before the unit of the component carrier and electrical component is inserted into the intended wire end terminals. This can make the unit off

Component carrier and electrical component easily to different terminal blocks and if more than two wire end connection terminals are available to be adapted to different wire end connection terminals.

According to a first preferred embodiment of

Invention is the component carrier, by means of which the electrical component is mechanically fixed to a module, as Aufrastaufsatz, preferably from

Plastic, e.g. made of polyamide 6.6.

The assembly consisting of the electrical component and the Aufrastaufsatz and possibly a mounting nut can be inserted as a unit with the free ends of the first and second lead wire ahead and simultaneously through the first and second conductor insertion channel in the first and second wire end terminal and is clamped by these in the same manner as wire ends of electrical cables and electrically contacted. Furthermore, the Aufrastaufsatz on locking means which engage with corresponding locking means of the terminal block housing to the assembly of the electrical component and the Aufrastaufsatz on the upper narrow side of the

Terminal block housing to lock. Thereby, a secure mechanical attachment of the component carrier to the terminal block housing can be achieved, although in this embodiment, the electrical connection of the electrical Component takes place at the terminal directly by means of the two two connecting wires.

The Aufrastaufsatz preferably has a bottom portion with an underside facing the terminal block and an upper side facing away from the terminal block and a retaining wing extending away from the upper side of the floor section. The latching means are preferably designed as latching feet, which are opposite from the underside of the bottom portion of the

Extending extension direction of the holding wing, so that the retaining wing extends from the bottom portion in the direction away from the terminal and the axial

Component housing extends transversely to the retaining wing, when the locking feet are locked in a locking groove of the terminal block housing and thus the assembly is mounted on the terminal. The Aufrastaufsatz therefore has in

Cross-section preferably has an inverted T-shape. Advantageously, the electrical component is space-saving with its axial housing parallel to the upper narrow side of the terminal block housing and can with its peripheral wall, possibly still improved by cooling fins on the peripheral wall, heat efficiently deliver to the ambient air.

Preferably, the retaining wing, which extends away from the upper narrow side of the terminal block housing, an opening through which the fastening bolt or threaded bolt of the electrical component through

extends. Hereby, the retaining wing can therefore be set between the second end face of the component housing and the fastening nut to the assembly consisting of the Aufrastaufsatz and the electrical component with the mounting nut to form, which can be snapped as a unit on the terminal block housing.

Many terminal block housing already have a central locking groove, which is normally used for locking

Marking label is determined (see, for example, catalog No. "Terminal Blocks", Version 2013/2014 by Phoenix Contact, eg page 470, www.phoenixcontact.com) It has been shown that this locking groove, which is present in any case, is very well suited to the invention To lock assembly there, ie the anyway - albeit for another purpose - existing locking groove for the present invention quasi purposeful alien This has the advantage that a variety of existing terminal blocks

can be used and without their

Terminal block housing to have to change the

Component carrier in the form of Aufrastaufsatzes can be snapped securely on the terminal block housing. As a result, a retrofittability of the invention to already

Existing terminal blocks given in a wide variety of applications

According to a second preferred embodiment of

Invention is the component carrier, by means of which the electrical component is mechanically fixed to a module, designed as a plug-in metal part consisting of a mounting head and at least one plug-in foot. In this case, second electrical connection of the electrical component to the attachment head with the pluggable metal part is firmly connected. The pluggable

Metal part continues the second electrical connection and thus assumes the electrical connection function of the second connecting wire (not present in this embodiment).

Thus, an assembly consisting of the plug-in metal part and the electrical component optionally with

Fixing nut formed, which as a unit

simultaneously inserted with the free end of the first lead wire through the first conductor insertion channel in the first wire end terminal and from this in the same way as a wire end of an electrical cable clamped and electrically contacted and plugged with the plug of the plug metal part forward in a further terminal of the terminal can be.

For contacting the plug-in foot of the pluggable

Metal part open up now even the following two

Options. The plug foot is through the second

Ladder insertion channel inserted into the second wire end terminal and is clamped by this in the same manner as a wire end of an electric cable or the

Terminal block has a bridge shaft and the

Plug foot is inserted into a terminal of the bridge shaft of the terminal block. Terminal blocks with one

Bridge shaft, which is usually two to multi-pole jumpers for potential bridging

can be found, for example, in catalog no. 3

"Terminal Blocks", version 2013/2014 from Phoenix Contact, for example page 471 top line, www.phoenixcontact.com.

The electrical component is thus by means of

Plug connection between the terminal block and the pluggable metal part, more precisely its plug-in foot on the

Fixed terminal, so that the electrical component by means of the plug-in metal part simultaneously both electrically connected to the terminal and mechanically attached to the terminal block. It has been found that the insertion of the plug foot into a conventional wire end terminal, in particular with a spring-loaded terminal with push-in technique (e.g., Phoenix Contact series PT), in the form of a spring clamp (e.g., Phoenix

Contact Series ST) or in the form of a clamped terminal with a cutting contact (e.g., Phoenix Contact Series QT), or in a conventional bridge well of a terminal already ensures sufficient mechanical stability to handle heavy electrical components such. Diodes of type SKN 2.5 or SKN 5 not only electric too

contact, but also mechanically safe at the

Fix terminal block. In particular, it has been shown that this inventive method of combined electrical contacting and mechanical fastening even has a good vibration resistance. The plug-in foot can even be designed so that one and the same plug-in foot can be plugged into both a wire end connection terminal and into a bridge shaft. In particular, the fastening head has an opening through which the fastening bolt or threaded bolt of the electrical component extends, and the fastening head is between the second end face of the component housing and the complementary

Fixing element or the fastening nut set. With this type of attachment, for example, diodes with axial housing and axial mounting bolt or Fix the threaded bolt effectively as the second electrical connection and at the same time make electrical contact.

Preferably, the opening in the mounting head is radially open, so that the fastening bolt or threaded bolt of the electrical component can also be used radially when the plug-in metal part is inserted in the terminal block. This facilitates replacement of the electrical device, e.g. in case of a defect, because the pluggable

Metal part can remain plugged in the terminal in the exchange.

Preferably, the pluggable metal part consists of a stamped metal sheet. Such a plug-in sheet metal part can be very easily punched on metal and can even remain essentially flat, so does not need

necessarily to be shaped. The pluggable

Metal part can therefore consist only of the mounting head and the plug-in foot, which is an integral

Forming metal strips.

Preferably, the pluggable metal part of copper sheet is stamped and tinned. The present design can allow a sheet thickness greater than 0.5 mm, which is why even very good conductive copper sheet can be used.

According to one embodiment of the invention, the pluggable metal part on two or more plug feet, which so

are dimensioned so that they adjacent to each other in Leitereinführkanäle or bridge shafts

Terminal blocks are inserted. This can be a

Multiple function, namely to the effect that the pluggable metal part at the same time on the one hand the electrical component mechanically attached to the terminal block and electrically contacted and on the other hand, the function of a jumper to

Potential bridging takes over. This may possibly

Jumper for potential bridging to be saved. This allows either the economical use of existing bridge shafts or the bridging of terminal blocks, which do not even have a bridge shaft, with simultaneous connection of the electrical component.

Preferably, the first connection wire of the electrical component is angled substantially at right angles, wherein the angled free end of the first connection wire and the insertion foot of the pluggable metal part in the same direction transverse to the axial design of the electrical

Component extend and form a U-shape by and large. This has the advantage that the distance between the angled free end of the first connection wire and the plug-in foot of the pluggable metal part can be freely adapted to the distance between the two associated wire end connection terminals or the distance between a wire end connection terminal and a bridge shaft before the

Unit is inserted from the plug-in metal part and the electrical component in the intended wire end terminals or the intended bridge shaft. Thus, the unit of component carrier and

electrical component easy to different

Terminal blocks or to different

Wire end connection terminals or bridge shafts. The invention further relates to the Aufrastaufsatz,

in particular as a component of the above

described arrangement for holding an electrical

Component of axial design, i. with an axial component housing, which a first and second

Has end face, which are axially opposite, and in which as the first electrical connection, a first lead wire axially from the first end face of

Component housing protrudes and wherein the second electrical connection of the electrical component as

Mounting bolt, in particular threaded bolt is formed, which axially from the second end face of the

Component housing protrudes. The Aufrastaufsatz includes a bottom portion with one of the terminals zuwendbaren bottom and one of

Terminal block turn-off top and extending away from the top of the bottom portion away

Retaining wings. Extending from the underside of the bottom portion opposite the direction of extension of the retaining wing locking means which with a locking groove on an upper narrow side of the terminal block housing, in particular with the central locking groove of the

Terminal block housing, which is usually intended for locking of label tabs are latched.

In this case, the retaining wing extends from the bottom portion in the direction away from the terminal block when the

Aufrastaufsatz is locked to the terminal block housing. The retaining wing has means for securing the

electrical component, e.g. an opening to the

Pushing through the fastening bolt or threaded bolt on, so that the axial component housing extends transversely to the retaining wing when the fastening bolt or threaded bolt by means of a complementary

Fastening element, in particular a corresponding fastening nut in the opening of the holding wing

is fastened or screwed, and the Aufrastaufsatz together with the screwed therein electrical

Component as a mechanically fixed unit can be snapped onto the terminal block housing. At the same time lock the locking means of the Aufrastaufsatzes in the

Locking groove of the terminal block housing and the rectified angled ends of the first and second terminal wire are in the respective wire end connection terminals

plugged and clamped in the same way as wire ends of electrical cables and contacted.

The invention further relates to the plug-in metal part, in particular as a component for the above

described arrangement for holding the electrical

Device housing protrudes and wherein the second electrical connection of the electrical component as a fastening bolt, in particular threaded bolt is formed, which axially from the second end face of the

Component housing protrudes.

The pluggable metal part or sheet metal part includes a mounting head and at least one integral with the Mounting head trained plug-in foot. Of the

Fastening head has an opening for the insertion of the fastening bolt or threaded bolt, wherein the axial component housing transverse to the pluggable

Metal part extends when the fastening bolt or

Threaded bolt by means of a complementary

Fastening element or a corresponding

Fixing nut is fastened or screwed into the opening of the fastening head, so that the pluggable metal part together with the screwed therein

electrical component as mechanically firmly connected unit can be placed on the terminal block housing. In this case, either: i) simultaneously the free end of the first connection wire through a first conductor insertion channel into a first

Cable end terminal of the terminal is inserted and from this in the same manner as a wire end of a

clamped and electrically contacted and the plug-in foot of the plug-in metal part is through a second conductor insertion channel into a second

electrically clamped and electrically contacted or ii) at the same time the free end of the first connection wire through a first conductor insertion channel into a first

clamped and electrically contacted and the plug foot of the pluggable metal part is in a Connection terminal of a bridge shaft of the terminal block inserted and clamped by this and electrical

contacted.

The electrical component is thereby by means of

Plug connection between the terminal block and the

plugged metal part attached to the terminal block, so that the electrical component by means of the plug-in metal part both electrically to the

Terminal block connected as well as mechanically at the

Terminal block can be attached.

1a to 3d show a first embodiment of the invention with a Aufaufaufsatzsatz 12. The Aufaufaufsatzsatz 12 is integrally molded from plastic, which is easier to produce than, for. a complex largely

closed plastic housing 4, such as e.g. in Fig. 12 is shown. The Aufrastaufsatz 12 is preferably made of polyamide 6.6, which meets the applicable fire protection regulations. The Aufrastaufsatz 12 has a bottom portion 14 in the form of a flat bottom plate and a retaining wing 16, which is integrally perpendicular to the

Bottom plate 14 extends from the top 14a upwards, so that the support wing 16 and the bottom plate 14 in the side view an upside down - easily

asymmetric - form T-shape. To stabilize the

Holding wing 16 16 16 stabilizing corners 18 are integrally formed on one side of the support wing. At the bottom 14b of the bottom plate 14 extend parallel to the retaining wing 16, two elongated locking feet 20. In the retaining wing 16, a central opening 22 is provided, through which a fastening bolt in the form of a

Threaded bolt, in this example an M4 threaded bolt, is durchsteckbar.

Referring to Fig. 2, a discrete electrical device 24, in this example a Semikron type SKN 2.5 power diode (see www.semikron.com) with a current I FAV = 2.5A at sin. 180 and T _a = 45 ° C at the

Aufrastaufsatz 12 attached. For this purpose, the threaded bolt 26 of the diode 24 is inserted through the opening 22 and fixed with a fastening nut 28 on the retaining wing 16. The diode 24 has an axial design with a in

Substantially cylindrical component housing 30, which has a first and second axial end wall 30a, 30b (see also Fig. 3b) and a peripheral wall 30c. The peripheral wall 30c has a plurality of cooling fins 32 to enhance the heat dissipation. The diode 24 of axial design has at its two front ends in each case a factory-provided connecting wire 34 a, 34 b. The first connecting wire 34a extends directly from the first end face 30a of the

Component housing 30 and the second lead wire 34b extending axially from the threaded bolt 26 at the second axial end face 30b of the component housing 30. In this diode design thus forms the threaded bolt 26, the second electrical terminal of the diode 24 and the second lead wire 34b jumps axially out of the

Threaded bolt 26 forth. For assembly, the electrical component 24 is inserted with the second connecting wire 34b and the threaded bolt 26 through the opening 22 and then with the

Fixing nut 28 bolted to the retaining wing 16. Then, the first and second lead wires 34a, 34b are angled perpendicularly at kinks 36a, 36b so that the free ends 38a, 38b of the lead wires 34a, 34b extend in substantially the same direction perpendicular to the axis of the component housing 30. Here, the

Distance of the angled free ends 38a, 38b are freely adapted to the predetermined distance of the respective wire end terminals in the terminal.

With reference to FIGS. 3 a to 3d, the assembly 40 illustrated in FIG. 2 will now be integrated as a unit onto at least one terminal block 50, in the present example, two

Terminal blocks 50, 50 'mounted and at an upper

Narrow side 50 a of the terminal 50 is attached. In the example shown here, the width B of Aufrastaufsatzes 12 is slightly larger than the width b of two terminal block housing 60 (see Fig. 3d). In general, it is advantageous that, depending on the size of the electrical component 24, the assembly 40 can cover one or more terminal block housings 50, and nevertheless, for example, the sliders 54a, 54b for releasing the wire-end connection terminals 56a, 56b formed in push-in technology remain accessible, since a separate, the electrical component 24 einhäusendes KunstStoffgehäuse 4 can be dispensed with (see Fig. 3a, 12). On the contrary, the diode 24 with the annular wall 30c of its housing 30 is exposed to the outside over the or the terminal block housings 60, so that heat without disturbing housing walls - at least laterally (Transversely to the extension direction of the terminal block housing 60 and parallel to the upper narrow side 60a of

Reihenklemmengehause 60) and upwards - can be delivered directly to the ambient air. Even down in the direction of the terminal block housing is enough air to be able to dissipate heat better than with a largely closed plastic housing, e.g. as in FIG. 12.

In particular, the cooling fins 32 can develop their effect well.

In the present example, the two free ends 38a, 38b of the two connection wires 34a, 34b of the diode 24 are inserted directly into the wire end connection terminals 56a, 56b, which are formed in this example in a push-in technique, and are electrically contacted there. The

mechanical attachment of the diode 24 and the assembly 40 via a latching of the locking feet 20 in a central locking groove 58 of the two terminal block housing 60. The terminal block housing 60 have at their upper

Narrow side 60a - this is the narrow side, from which ladder in Leiteinführkanäle 62a, 62b in the

Aderendanschlussklemmen 56a, 56b are introduced - by default, such a central locking groove 58. The central detent groove 58 is normally intended and is normally used to secure tabs to the respective terminal block 50. Accordingly, the locking groove 58 extends transversely to the plane of extension of the terminal block housing 60 continuously through a

Variety of juxtaposed

Terminal block housings 60. As a result, the width B of the Aufrastaufsatzes 12 can be adjusted freely to the size of the desired electrical component 24 and the Aufrastaufsatz 12, as described above, if desired, in a plurality of adjacent terminal block housings 60 are locked. The width B of the Aufrastaufsatzes 12 can therefore independent of the width of the individual terminal block housing 60 to the size of

electrical component can be adjusted.

At the upper narrow side 60a opposite the lower narrow side 60b, the terminal block housing 60 with a retaining groove 61 in a known manner on a holding rail, not shown, in particular a DIN rail, snapped.

Referring to FIG. 4, the width of the assembly 40 is only slightly larger than the diameter of the

cylindrical diode housing 30, possibly including the cooling fins 32, so that the sparingly available space across the plane of extension of the terminal blocks 50 optimal

can be exploited. As a result, in this example, the terminal block 50 ', which directly

adjacent to the terminal block 50 into which the type SKN 2.5 diode is inserted, a side wall 52 is attached. As can be seen in Figs. 2 to 4, there is the

Assembly 40 only from the electrical component 24 with its integral threaded bolt 26 and its two connecting wires 34a, 34b, the Aufrastaufsatz 12 and the fastening nut 28. This firmly screwed assembly 40 can be snapped as a unit on or on the terminal block housing 60, wherein the angled free ends 38a, 38b of the connecting wires 34a, 34b in the Inserted conductor insertion channels 62a, 62b and finally inserted into the wire end termination terminals 56a, 56b. Here, the free ends 38a, 38b directly from the wire end connection terminals 56a, 56b - formed in this example in push-in technology - clamped and contacted and simultaneously the Aufrastaufsatz 12 is locked with its locking feet 20 in the transverse locking groove 58.

It can be seen that the wire end connection terminals 56a, 56b, which are used for clamping and contacting the free ends 38a, 38b of the connecting wires 34a, 34b of the diode 24

used, no special extra

Terminals are, but that this is the case in each terminal anyway

Wire end terminals, e.g. with the usual for this

Clamping springs, acts, which are normally intended for clamping and contacting the wire ends to be connected cable ladder and used. Referring to Figs. 5 to 7 is a second

Embodiment of the component carrier designed as a plug-in metal part 72. The plug-in metal part 72 is made of copper sheet, stamped and tinned, and has a mounting head 74 for attaching the electrical

Component 24. For this purpose, the fastening head has an opening 82, which is open towards the upper side 74a of the fastening head 74, in the form of an oblong hole. One or more plug-in feet 90 extend integrally on the underside 74b of the fastening head 74. The variant of the plug-in metal part 72 in FIG. 5 has a plug-in foot 90, that of the plug-in metal part 72 'in FIG

Plug feet 90 on and the variant of the pluggable Metal part 72 "in FIG. 7 has four plug-in feet 90. Each plug foot 90 extends with a base strip 92 from the underside 74b of the mounting head 74 and tapers towards a terminating free plug end 93 which is adapted to both in a

Bridge well 64 of the terminal 50 as well as in one of the wire end terminals 56a, 56b to be pluggable, although they typically use different clamping techniques.

Referring to FIG. 8, a diode 84, in FIG

present example of the type SKN 5 with a direct current IFAV = 5 A at sin. 180 and T _a = 45 ° C, with cooling fins 32 attached to the mounting head 74. The diode 84 is of axial design as the diode 24, but due to the higher power overall slightly larger. The diode 84 has a first electrical connection with a first

Lead 34a, which, as in the diode 24, axially from the first end face 30a of the axial

Diode housing 30 extends and, as in the diode 24 in Fig. 2 to 4, angled. At the second axial

Front side 30b of the diode housing 30 starts

Threaded bolt 26 axially protruding, which in this

Diode design 84 has no own connection wire. The threaded bolt 26 can be used both axially and radially in the opening 82 and screwed to the fastening nut 28.

The thus formed assembly 40 'consisting of the diode 84 with the only a single first lead wire 34 a and the threaded bolt 26 and the plug-in metal part 72' and the fastening nut 28, which is a fixed form a bolted unit, which is as shown in Fig. 8, can be inserted as a whole in the terminal block 50. Referring to Figs. 9a and 9b, the assembly 40 'is a total of three wire end terminals of two

Terminal blocks 50, 50 'inserted. Here it is

angled free end 38a of the first lead wire 34a inserted into the first wire end terminal 56a of the terminal block 50 and clamped and contacted. The

plug-in metal part 72 is with its two feet 90 in the second wire end terminal 56b of the same

Terminal block 50 and inserted into the second wire end connection terminal 56b of the adjacent terminal block 50 '. As a result, the assembly 40 'causes in addition to the electrical

Connecting the diode 84 a bridge between the two adjacent terminal blocks 50 and 50 '.

As can be seen in Fig. 9a, due to the open design of the assembly 40 ', most of the slides 54, 54a are free to open the associated wire end terminal

accessible, in particular also the first slider 54a of the first wire end connection terminal 56a of the terminal block 50, in which the first connection wire 34a is inserted. But also the first slider 54a of the adjacent terminal blocks 50 ', 50' ', 50' '' are freely accessible. Depending on the design of the diode, the second slider 54 b of the second

Aderendanschlussklemmen 56b, in which the two plug-in feet 90 are inserted, accessible or not accessible. If they are not accessible, the diode 84 can still after loosening the fastening nut 28 and actuation of the first slider 54a of the terminal 50 are replaced.

The terminal blocks 50, 50 ', 50' ', 50' '' have in this example wire end connection terminals in push-in technology

(Phoenix Contact Series PT), but both are

Embodiments of the component carrier 12, 72 or the assembly 40, 40 'also for use in tension spring terminals

(Phoenix Contact ST series) and used in

Quick connection terminals with cutting technology (Phoenix Contact series QT) suitable.

As can be seen in FIGS. 9a and 9b, the diode 84 is arranged to float freely parallel to the terminal block housings 60 above their upper narrow sides 60a and is mechanically fixed to the two terminal blocks 50, 50 'substantially by the pluggable metal part 72'. The first connection wire 34a may also have something to

Contribute stabilization, but in particular the variants 72 ', 72' 'are held very stable with more than one plug 90 by plugging in the wire end terminals 56b of several adjacent terminal blocks, especially against occurring torques. Overall, this type of combined electric

Contacting and mechanical fastening advantageously vibration resistant.

Figs. 10a and 10b show a Figs. 9a and 9b

corresponding assembly of the assembly 40 '', which includes the plug-in metal part 72 '' with four mating feet 90 of FIG. The advantages are the same as in the variant according to FIGS. 6 and 9a / b, wherein the attachment even more torque-stable and

vibration-resistant than with the variant 72 'with the two feet 90 is. This quadruple bridging is achieved without further bridge connector.

Referring to Figs. 11a to 11e, a diode 94 having a direct current I FAV = 2.5 A at sin. 180 and T _a = 45 ° C attached to a further variant of the plug-in metal part 12 '''. In this example, the assembly 40 '''is mounted in reverse orientation on the terminal blocks 50, 50' in that the first angled free end 38a of the first lead wire 34a is clamped and contacted in the second lead end terminal 56b. The two plug-in feet 90 of the plug-in metal part 72 '''are not inserted in wire end connection terminals, but in the bridge shaft 64, which is normally provided for the insertion of jumpers. The

Plug feet 90 'are therefore designed so that they on the one hand in the terminals 66 of the bridge shaft 64 and on the other hand, if necessary, in the

Cable end terminals are clamped, although the

Terminals 66 of the bridge shaft 64 and the

Wire end terminals 56a, 56b are of different types.

Referring to Figs. 11c and 11d, an example of a termination technique in the bridge well 64 is shown. The connection terminal 66 has contacts 67 which are prepared for receiving a jumper 68 of the type FBSR (see Catalog No. 3 "Terminal Blocks", Version 2013/2014 from Phoenix Contact, eg page 474, www.phoenixcontact.com) Variant of the plug foot 90 'has a central gap 96 in the plug-in foot 90 ', wherein the central gap 96 subdivides the plug-in foot 90' into two plug-leg legs 98. When the plug foot 90 'is plugged into a rectangular opening 100 in the current bar 102, the inner edges of which form the contacts 67, the leg legs 98 have sufficient transverse flexibility to deflect elastically inwardly (shown by dash-dotted lines 104 in FIG Fig. Lld) to in the opening 100 in the

Current bar 102 at the inner edges of the opening 100 to be securely clamped and contacted by frictional engagement.

However, PV bridges or others can also be used here

Contact techniques are used.

Since the terminals 66 of the bridge shaft 64 do not require active opening with a slider, but the two plug-in feet 90 without additional release mechanism can be easily pulled out of the terminals 66 again (no push-in, Zugfeder- or

Cutting technique), this variant of the plug-in metal part 72 '' 'does not require a slot for fixing the diode 94. In this variant of the pluggable metal part 72' '', the entire assembly 40 '' 'including the

plug-in metal part 72 '' 'from the used

Terminals 66, 56b pulled out, with only the second slider 54b of the second wire end connection terminal 56b, in which the first lead wire 34a is inserted, needs to be actuated.

Referring to Figs. 11a and 11c, the slightly asymmetric shape of the pluggable metal part 72 '''contributes to the accessibility of the second slider 54b. In summary, the invention relates to an arrangement of a terminal and a means of a

Component carrier attached to the terminal block

external electrical component. The electric

Component is mechanically fastened by means of the component carrier to the terminal block. The electrical contact is effected by either two connecting wires of the electrical component directly in

Core end terminals (in particular with push-in (PT), tension spring (ST) or cutting technology (QT)) are plugged or the component carrier itself as pluggable

Sheet metal part is formed and then a lead wire of the electrical component are inserted into a wire end terminal and a plug-in foot of the pluggable sheet metal part in a wire end terminal or in a bridge shaft of the terminal.
