Description

The invention relates to an electronic device according to the preamble of claim 1 and to a method for producing an electronic device.

Such an electronic device comprises a housing which has two side walls spaced apart from one another in a rowing direction and forming a receiving space between them. A printed circuit board, which has a side edge extended along the direction of insertion, can be inserted into the receiving space of the housing along a direction of insertion transverse to the mounting direction and is accommodated in a mounting position in a position perpendicular to the mounting direction in the receiving space.

Such an electronic device, for example, can be combined with other electronic devices along the arrangement direction, so that a plurality of electronic devices are lined up along the arrangement direction. The electronic device can, for example, be accommodated together with the other electronic devices on a mounting rail, so that an electrical assembly is created in this way, which can take over, for example, control or evaluation functions in the context of an industrial plant.

Electronic components are in this case arranged on the printed circuit board, which can be inserted into the housing in order to form the electronic device. The circuit board extends in the mounting position parallel to the side walls, between which the receiving space is formed, and is enclosed in the housing in a protected manner.

Desirable is an electronic device that can be easily, in particular for inserting and fixing the circuit board in the housing, mounted, but variably also depending on the design of electronic components of the circuit board, for example, with terminals or display and control elements can be equipped.

At one of the DE 44 28 687 C1 known electronic device, a printed circuit board can be used together with a pre-assembled on operating elements of the circuit board housing part in a housing. In the mounted position, the housing part closes an opening of the housing.

At one of the EP 2 399 435 B1 known electronic device housing are preassembled with connection chambers on a circuit board. The circuit board can then be placed together with side panels on a housing base to complete the electronic device.

The object of the present invention is to provide an electronic device and a method for producing an electronic device that can be configured as a function of the application, which enable a simple and thus cost-effective installation of the electronic device with variable placement, in particular with electrical and / or mechanical connections.

This object is achieved by an article having the features of claim 1.

Accordingly, at least one attachment part has at least one engagement receptacle with which the at least one attaching part can be attached to the side edge of the printed circuit board and connected in an attached position to the printed circuit board.

The at least one Ansetzteil is thus recognized with the engagement receptacle on the side edge of the circuit board and is held in particular non-positively or positively on the circuit board.

To the circuit board can thus be applied in a modular manner Ansetzteile which are positively connected in the attached position or positively connected to the circuit board. For this purpose, the attachment parts each have an engagement receptacle with which the attachment parts can be attached to a side edge of the printed circuit board and which, for example, can be shaped slot-shaped for receiving the side edge of the printed circuit board. About such Ansetzteile functional assemblies can be provided on the circuit board. The Ansetzteile can here also, as will be described below, serve to connect the circuit board to the housing and complete the housing in the mounting position such that the receiving space in which the circuit board is received, is completed to the outside. For this purpose, the Ansetzteile can form a positive connection with the side walls of the housing.

Characterized in that the connection of Ansetzteile with the circuit board in non-positive or positive manner by engaging the engagement recording with an associated side edge of the circuit board, there is a simple installation to which the Ansetzteile (only) must be attached to an associated side edge of the circuit board. Different Ansetzteile can here be combined with each other to equip the circuit board for the desired function and design with a suitable combination of Ansetzteilen.

The engagement receptacle of Ansetzteils can be formed, for example, on one of a body projecting web of Ansetzteils and slit-shaped. In the engagement recording is the printed circuit board with its side edge inserted to connect the Ansetzteil positively or positively with the circuit board.

To produce a positive connection, the Ansetzteil, for example, have a latching hook, which is deformed when attaching the Ansetzteils to the circuit board (slightly) and after reaching the scheduled position snaps into an associated latching opening of the circuit board. About such a latching hook and its engagement in the detent opening of the circuit board, the attachment part is thus fixed to the circuit board such that the Ansetzteil not readily, at least not without loosening the latch, can be removed from the circuit board.

To produce a frictional connection, the engagement receptacle can for example form an interference fit with the associated side edge of the printed circuit board in that the (slot-shaped) engagement receptacle has a clear width which is smaller than the thickness of the printed circuit board in the region of the side edge or a constriction in the engagement receptacle by a Fixation nose is formed. When attaching the Ansetzteils to the circuit board thus creates a positive connection.

In one embodiment, the Ansetzteil a plurality of transversely to the insertion direction spaced apart engagement receptacles for connecting the Ansetzteils with a plurality of mutually parallel extending, to be used in the housing printed circuit boards. About the Ansetzteil thus several circuit boards can be connected together and held each other in a defined position.

In a specific embodiment, the Ansetzteil two transversely to the insertion direction offset from each other (groups of) engaging recordings, via which the Ansetzteil can be connected to two parallel aligned printed circuit boards.

By connecting one or more Ansetzteile with one or more printed circuit boards, a preassembled unit is created, which can be used as such in the receiving space of the housing. If a plurality of printed circuit boards are provided, the printed circuit boards can be connected to one another via the attachment parts and held in a defined position relative to one another, so that the printed circuit boards can be jointly inserted into the receiving space of the housing.

In one embodiment, the printed circuit board has along the insertion direction extended, opposite side edges on which attachment parts can be arranged. The attachment parts are thus lined up on opposite side edges of the circuit board and combined with each other, so that the Ansetzteile in a state connected to the circuit board extending along the side edges of the circuit board.

In one embodiment, the Ansetzteile each have two first guide means for guiding on second guide means of the side walls of the housing. The Ansetzteile are mounted together with the circuit board on the housing such that when inserting the circuit board in the receiving space, the Ansetzteile are guided displaceably on the first guide means on the second guide means of the side walls of the housing along the insertion direction and connect the side walls positively in the mounting position ,

One or more Ansetzteilen can be pre-assembled on the circuit board to insert the circuit board together with the attachment parts arranged thereon in the housing. In the pre-assembly, the Ansetzteile are connected to the circuit board and thus together with the circuit board form a preassembled unit that can be attached to the housing of the electronic device. The preparation of this preassembled unit then takes place, according to an advantageous embodiment, in a guided manner in that first guide means of Ansetzteile with second guide means of the side walls of the housing are engaged so that the assembly, so the Ansetzteile together with the circuit board in the housing can be inserted and the printed circuit board is in a defined position within the receiving space. In the mounting position fix the Ansetzteile the circuit board in the receiving space by the circuit board is connected via the Ansetzteile with the side walls. The Ansetzteile extend here between the side walls and connect the side walls form-fitting manner with each other, so that the housing is completed and the Ansetzteile complete example, the housing to the outside.

Any desired attachment parts for providing completely different functions can be attached to the printed circuit board. Thus, depending on a desired configuration and function of the electronic subassembly provided by the printed circuit board, the printed circuit board can be equipped with different attachment parts in order to insert the pre-assembled subassembly thus created into the housing and thereby assemble the electronic device.

For mounting, the first guide means of the attachment parts and the second guide means of the side walls of the housing preferably engage with each other in such a manner be brought that the Ansetzteile are firmly connected in a direction perpendicular to the insertion direction plane with the side walls, along the insertion direction but to the side walls are displaced until the mounting position is reached and the circuit board, for example, additionally locked in the final position reached in the housing. The Ansetzteile are thus defined in the direction perpendicular to the insertion direction plane to the side walls, so connected to the side walls that a firm connection between the Ansetzteilen and the side walls, but the Ansetzteile along the insertion direction to the side walls are displaced until the mounting position is reached. The engagement of the first guide means with the second guide means thus provides a guide for the Ansetzteile on the side walls, due to which the Ansetzteile and about the circuit board in a defined manner to the side walls are displaced without the Ansetzteile thereby readily out of their Can solve engagement with the side walls.

The guidance of the attachment parts on the side walls can be provided, for example, in that each first guide device can be brought into positive engagement with an associated second guide device by making engagement of a web into a groove in the sense of a tongue-and-groove connection. One of the guide means thus has a web which engages in an associated groove of the other guide means and thereby provides a guide along the insertion direction, but at the same time the Ansetzteile in the plane perpendicular to the insertion direction together so that the engagement between the Ansetzteilen and the side walls not easily solvable.

In a specific embodiment, the second guide means of the side walls each have a web, while the first guide means of each Ansetzteils each have a engageable with the web engaging groove. Each Ansetzteil thus has two grooves, which can be brought into engagement with a respective web of a side wall, so that about the Ansetzteil is guided displaceably on both side walls, but a not easily detachable connection between the Ansetzteil and the side walls is created, so that the attachment part is fixed positively in a direction perpendicular to the insertion direction extending plane to the side walls.

In an alternative embodiment, it is also conceivable that the first guide devices of the attachment parts each have a web and the second guide devices of the side walls each have a groove, with which a web of an associated first guide device can be brought into engagement.

In another embodiment, it is also conceivable that the guide system is designed as a whole or half dovetail guide with inclined groove-web system.

The positive connection between the guide devices is in particular such that the attachment parts are fixed in a direction perpendicular to the insertion direction extending plane to the side walls and thus a connection between the Ansetzteilen and the side walls is created. To prevent this, that a Ansetzteil along a transverse direction which is transverse to the mounting direction and transverse to the insertion direction, can be disengaged from an associated web, a blocking web can be arranged in the region of the groove, which blocks the web in the groove and prevents slipping out of the web from the groove along the transverse direction. The web can, for example, engage in a groove pointing in the transverse direction of engagement in the groove. The blocking bar blocks a sliding out of the web against the direction of engagement of the groove and thus ensures the engagement of the web in the groove.

In order to connect the Ansetzteile in a plane perpendicular to the insertion direction fixed (but slidable along the insertion direction but to the side walls to the mounting position) with the side walls, the groove surrounds the guide web preferably on four sides. Steps that form the guide bar with the associated side wall, in this case in contact with the blocking web and a boundary portion of the groove. The guide web is thus held positively in engagement with the groove and can not be moved out of the groove in a plane perpendicular to the insertion direction.

In one embodiment, the attachment parts are extended in the assembly position along the direction of arrangement between the side walls. The Ansetzteile may, for example, extend flat along the mounting direction and the insertion direction and may for example provide a boundary of the receiving space to the outside, so that the Ansetzteile complete the housing and complete together with other housing sections the receiving space of the housing to the outside.

The attachment parts can, for example, when viewed in a plane spanned by the arrangement direction and the insertion direction, each have a body which provides a surface element which is viewed along the direction of insertion defines a division of the respective Ansetzteils. The body may, for example, have a rectangular basic shape (in a plane spanned by the arrangement direction and the insertion direction), with a pitch corresponding to a predetermined smallest division unit or an integral multiple of the predetermined smallest division unit. Several attachment parts can be lined up along the insertion direction and then arranged on each other on the circuit board, so that the circuit board can be equipped in a modular manner with different combinations of Ansetzteilen.

Within the framework of a modular system, a plurality of different attachment parts can thus be provided, which can be combined variably and in different ways with one another. By virtue of the attachment parts having a pitch which corresponds to a predetermined smallest division unit or an integral multiple of the predetermined smallest division unit, basically any combination of attachment parts can be lined up along the insertion direction in such a way that a combination of attachment parts with a predetermined overall length results, corresponding, for example, the length of a housing opening (measured along the direction of insertion), which is to be closed by the Ansetzteile. A circuit board can thus be equipped with very different combinations of Ansetzteilen to be used together with the Ansetzteilen in the receiving space of the housing and thus form the electronic device.

By using different Ansetzteile in combination with each other different functions can be provided on the circuit board, as will be explained below. This results in a flexibly usable modular system, by means of which very different electronic devices can be manufactured in a variable manner and configured application-related. In particular, the attachment parts can provide a device interface from the printed circuit board stage of the manufactured electronic device to the outside.

The predetermined smallest division unit (TE for short) defines a basic length along the insertion direction. For example, some attachment parts may have a pitch corresponding to the simple division unit. Other attachment parts may have a pitch corresponding to twice the pitch, that is twice as long as the pitch unit. Again other attachment parts may for example have a pitch corresponding to three times the division unit. Different Ansetzteile can thus be combined along the insertion direction with each other to create a combination of Ansetzteilen with a predetermined length. If, for example, a housing opening into which the combination of attachment parts is to be inserted has a length corresponding to five times the division unit, attachment parts can be combined with one another in such a way that the total length results in accordance with the fivefold division unit.

The attachment parts are in this case to be arranged on the circuit board, that they protrude along the mounting direction of the circuit board. While the printed circuit board extends flat along a plane spanned by the insertion direction and the transverse direction, the attachment parts are arranged on the side edges of the printed circuit board extending along the insertion direction and perpendicular to the plane of the flat printed circuit board, ie along the mounting direction, with respect to the printed circuit board.

For mounting the circuit board in the housing, the circuit board is equipped with a combination of Ansetzteilen and used together with the Ansetzteilen in the housing. In this case, it can preferably be provided that the printed circuit board is fixed in the mounting position (exclusively) via the Ansetzteile in the receiving space of the housing, so that a connection between the circuit board and the housing (only) is created indirectly via the Ansetzteile. The circuit board is thus determined via the Ansetzteile in the receiving space of the housing.

The Ansetzteile can take on very different functions and this can be configured very different.

For example, an attachment part can provide a diaphragm part for an electrical connection (electrically) connected to the circuit board. For this purpose, the Ansetzteil example, have an opening through which a connector part can be connected to the electrical connection.

In another embodiment, the Ansetzteil can realize, for example, a terminal device having one or more insertion openings into which electrical conductors (for example, with stripped cable ends) or optical conductors (optical fibers) can be inserted for the purpose of electrical or optical contact. Such a clamping device can be realized, for example, as a spring-loaded terminal or the like. Different terminal devices may in this case have plug openings for inserting different electrical conductors with different cable cross-section. Clamping devices of different pole density (ie one of the number of terminals corresponding number of poles per Division unit) for connecting different conductors can thus be combined with each other and arranged on the circuit board.

However, it is also conceivable and possible for an attachment part to realize a flat wall element (without further electrical function) for closing the housing to the outside. Such a planar wall element can, for example, provide a closure for the housing. Such a planar wall element can also serve as a so-called spacer in order to provide a spatial separation between electrical components, for example between electrical terminals, and to prevent an electrical interaction between the electrical components (in the sense of increasing a creeping distance).

In yet another embodiment, the attachment part can also provide a grid element, via which, for example, a cooling for an enclosed in the receiving space electronic assembly can be provided.

The Ansetzteile can also controls such as switches (for example, DIP switches), regulators (for example, for a potentiometer), displays, for example in the form of light-emitting diodes or displays, an electrical fuse or mechanical or electrical functional elements, for example in the form of a Provide a screw for attaching the housing to another assembly, for example, within a cabinet, or in the form of a Schirmungsauflage for producing an electromagnetic shield or a strain relief for a cable to be determined thereon.

Different attachment parts may in this case have a different coloration, which signal an electrical function (such as L / N / PE, EXi, +/-, signal type, safety or the like, which are usually indicated by a specific color coding). This has the technical advantage that a subsequent local printing of the housing, as in conventional electronic devices, can be omitted. If a housing of an electronic device sections to have a specific color or mark, so a corresponding Ansetzteil can be used and attached to the housing, thus providing a desired color or marking.

The electronic device can preferably be combined with other electronic devices by the electronic devices lined up along the mounting direction and secured to, for example, a mounting rail. The electronic device can for this purpose have a fastening device, for example in the form of a latching device, via which the electronic device can be fixed to the mounting rail.

The object is also achieved by a method for producing an electronic device, in which a printed circuit board along an insertion direction in a receiving space of a housing is used, which is formed between two side walls which are spaced along a direction transverse to the direction of insertion direction to each other, and in a Assembly position is received in a direction perpendicular to the direction of the direction of attachment in the receiving space. It is provided that at least one Ansetzteil is recognized with at least one engagement receptacle on a side edge of the circuit board and is connected in an attached position with the circuit board.

The advantages and advantageous embodiments described above for the electronic device are analogously also applied to the method, so that reference should be made in this regard to the above.

1 and 2 show an embodiment of an electronic device 1 that is a case 10 and one in the housing 10 enclosed electronic assembly in the form of a printed circuit board and disposed thereon electronic components. The electronic device 1 Can via a fastening device 105 at a bottom 104 of the housing 10 to a mounting rail 2 attached and thereby along a direction of arrangement T in a juxtaposed manner with other electronic devices 1 be combined.

The housing 10 has two perpendicular to the mounting direction T stretched, along the arrangement direction T mutually spaced side walls 100 . 101 as well as end faces 102 . 103 on, which is the essentially cuboid housing 10 define. The side walls 100 . 101 are flat extends such that other electronic devices 1 on both sides of the electronic device 1 attached and with the electronic device 1 on a mounting rail 2 can be combined.

Like this 3 to 8th in which different phases in the assembly of the electronic device 1 can be seen, form the side walls 100 . 101 between them a recording room 15 , in a printed circuit board 12 in a direction of insertion e can be used such that in a mounting position, the circuit board 12 in the recording room 15 taken while keeping parallel to the side walls 100 . 101 extends. On the circuit board 12 For example, different electronic components, for example electronic components in the form of electronic circuits, may be arranged, which may be an electronic assembly of the electronic device 1 form.

To the circuit board 12 are attachment parts 13 to arrange, which may have different functions and together with the circuit board 12 on the housing 10 to be assembled. The attachment parts 13 become along the insertion direction e extended side edges 121 . 122 the circuit board 12 arranged and stand in connected position along the direction of arrangement T from a surface 120 the circuit board 12 in front.

The electronic device 1 can be made by means of a modular system, as part of a combination of a variety of different Ansetzteilen 13 selected attachment parts 13 on the circuit board 12 arranged and the circuit board 12 with attached parts attached thereto 13 in the case 10 is used, in particular a desired electrical functionality for the electronic device 1 to provide.

How out 9 can be seen, very different Ansetzteile 13 present and form a modular system from which can be selected to the circuit board 12 to equip in a variable manner and to the electronic device 1 to provide very different functionalities. The attachment parts 13 here in each case, considered along the insertion direction e , a division X1 . X2 . X3 . X6 . X6 on, that of a predetermined smallest division unit X1 or an integer multiple of this predetermined smallest division unit X1 equivalent. This allows different attachment parts 13 in (almost) arbitrary manner to combine with each other to a desired electrical and / or mechanical function of the circuit board 12 and the electronic device 1 to provide.

For example, have attachments 13 in the form of wall elements 13B in the example according to 9 divisions X1 . X2 . X3 . X6 . X9 on, which differ from each other. A first wall element 13B has, for example, a division X1 on, that of the predetermined smallest division unit X1 equivalent. A second wall element 13B has a division in contrast X2 on, which is twice the smallest division unit X1 equivalent. Another wall element 13B has a division X3 on, which is three times the smallest division unit X1 equivalent. Other wall elements 13B have a division X6 . X9 to six times or nine times the smallest division unit X1 equivalent.

Likewise, in the example according to 9 also the other attachments 13 a Division on, the smallest division unit X1 or an integer multiple of the smallest division unit X1 equivalent. The attachment parts 13 can be variably combined with each other in this way, for example, a combination of Ansetzteilen 13 to create with a predetermined total length, which is exactly in a designated housing opening 106 of the housing 10 fits, as for example in 1 and 2 is shown.

How out 3-8 can be seen, the housing has 10 on each front side 102 . 103 one housing opening each 106 on, in this embodiment, a length (measured along the insertion direction e ) of nine times the smallest division unit X1 having. Accordingly, in each housing opening 106 For example, just three attachment parts 13 with a division X3 according to the triple division unit X1 be arranged, as for example 1 and 2 is apparent.

The attachment parts 13 form, for example, panel parts for connection devices 14 the circuit board 12 (left in 3 ) or terminal devices for connecting electrical conductors (right in 3 ) and before inserting the circuit board 12 in the recording room 15 of the housing 10 with the circuit board 12 connected, so that a preassembled unit of the circuit board 12 with the attachment parts arranged thereon 13 is created, as for example 3 and 5 and 6 is apparent. The thus created preassembled unit can then in the insertion direction e on the housing 10 be mounted by the attachment parts 13 to the side walls 100 . 101 of the housing 10 attached and in the insertion direction e on the side walls 100 . 101 be deferred.

The attachment parts 13 each have two first guide means 133 in the form of a groove, with guide webs 107 at the lateral edges of the side walls 100 . 101 can be engaged to the attachment parts 13 on the side walls 100 . 101 defer and so the circuit board 12 in the recording room 15 of the housing 10 introduce.

The recording room 15 is between the side walls 100 . 101 formed along the array direction T spaced apart and in the region of the end faces 102 . 103 above each of a lower, fixed wall section 109 housing openings 106 release. By pushing on the attachment parts 13 with the grooves of the guide devices 133 on the guide bars 107 the side walls 100 . 101 become the attachment parts 13 - like this 7 it can be seen - such between the side walls 100 . 101 pushed that the openings 106 in the area of the front sides 102 . 103 be closed and the housing 10 at its ends 102 . 103 thus through the lower, fixed wall sections 109 together with the attachment parts 13 is locked, like this 8th is apparent.

After insertion of the attachment parts 13 and the circuit board 12 existing preassembled unit is the housing 10 through a housing cover 11 closed, leaving the circuit board 12 not from the recording room 15 can fall out and thus in the recording room 15 is secured. The housing cover 11 shows how out 8th evident, a body 110 on, on the side bars 111 are formed with connecting webs 108 at the upper edges of the side walls 100 . 101 latch when the housing cover 11 to the housing 10 is set.

In the mounting position is the circuit board 12 in the recording room 15 of the housing 10 edged. The side walls 100 . 101 are laterally over the Ansetzteile 13 connected to each other, so the recording room 15 of the housing 10 laterally over the attachment parts 13 is completed.

The attachment of the attachment parts 13 to the side walls 100 . 101 of the housing 10 takes place in a guided manner by the first guide means 133 the attachment parts 13 with the second guide means 107 the side walls 100 . 101 positively engaged and the Ansetzteile 13 in the insertion direction e in a guided way to the side walls 100 . 101 be moved. As for example from the enlarged view according to 4 in synopsis with 12 it can be seen are the leadership facilities 133 the attachment parts 13 formed by grooves which are longitudinal along the insertion direction e are extended and engaged with a respective associated guide bar 107 on the side edge of an associated side wall 100 . 101 provide such that one in a plane perpendicular to the insertion direction e firm connection between the attachment parts 13 and the side walls 101 . 101 is created, the attachment parts 13 along the insertion direction e but to the side walls 100 . 101 are displaceable. One every guide device 133 has for this purpose a rear side of the groove shaped, along the insertion direction e extended blocking bar 138 on, the engagement of an associated guide bar 107 in the groove of the guide device 133 ensures such that the guide bar 107 not along the transverse direction Q disengaged from the groove of the guide means 133 can get.

Every guide bridge 107 forms to the associated side wall 100 . 101 stages 107A . 107B out with the blocking jetty 138 and with an outer boundary section 139 the groove of guide means 133 in abutment so that above the guide bar 107 sliding in the guide device 133 the associated attachment part 13 is held and not, viewed in a plane transverse to the insertion direction e , can get out of trouble, like this in 12 is shown. There is thus a positive Umgriff for the guide bar 107 in the groove of the guide device 133 , due to which the guide bar 107 in the leadership facility 133 positive fit (but along the insertion direction e displaceable) is held.

This embodiment of the guide devices 133 and the guide bars 107 causes the attachment parts 13 in a defined way on the side walls 100 . 101 can be deferred. This also causes, in the mounting position, a firm connection between the Ansetzteilen 13 and the side walls 100 . 101 is created, which is resilient and an (unwanted) loosening of the attachment parts 13 from the side walls 100 . 101 reliably prevented.

Like, for example 3 and 4 can be seen on both sides of the circuit board 12 on the side edges 121 . 122 each a plurality of along the insertion direction e adjoining, adjacent Ansetzteilen 13 arranged. The attachment parts 13 each have a body 130 on, which is a square basic shape (considered in one by the insertion direction e and the mounting direction T spanned level), so that different Ansetzteile 13 combined in a modular manner and on the circuit board 12 can be arranged.

The attachment parts 13 are part of a modular system and can be selected in a desired combination to an electronic device 1 to produce with proper functionality. The attachment parts 13 can take over very different functions and can be designed quite differently, as shown in an overview in 9 is shown.

So can attachments 13 as clamp devices 13A be configured, for example, plug-in opening 134 in which electrical conductors (with stripped conductor ends) can be inserted to the electrical conductors to an associated circuit board 12 to join. About electrical contact pins 136 can the clamp devices 13A at contact openings 123 the circuit board 12 (please refer 10 ) are arranged to the terminal devices 13A electrically and mechanically on the circuit board 12 set. The clamp devices 13A For example, they may be implemented as spring-type terminals or the like, and enable (simple) connection of electrical conductors.

Different terminal devices 13A can be differently dimensioned plug openings 134 have for receiving conductors of different line cross-section, as is apparent from 9 is apparent. So have the in 9 Clamping device shown above 13A and the in 9 Clamping device shown below 13A differently dimensioned plug-in openings 134 for the insertion of conductors with different conductor cross-section.

In an alternative embodiment can Ansetzteile 13 also as wall elements 13B be designed that a flat finish for the housing 10 can provide and have different sizes.

In another alternative embodiment, attachment parts 13 grid elements 13C provide, for example, a cooling for one in the housing 10 enclosed electronics assembly can be provided.

In yet another embodiment, the Ansetzteile 13 blind members 130 realize the electrical connection devices 14 For example, connectors for providing a coaxial port, a network port, a USB port, or a parallel or serial port can be attached. The panel parts 130 have openings 135 on, via the connection of connectors to the connection devices 14 is possible.

Conceivable are also possible other embodiments of attachment parts 13 , For example, the attachment parts 13 controls 13F (for example, switches), displays 13E (LEDs, displays) or mechanical functional components 13G for example with an externally protruding screw flange 16 for fixing the housing 10 on an external unit or the like.

The attachment parts 13 are on the circuit board 12 to arrange in this way a preassembled unit, which on the housing 10 for completing the electronic device 1 can be mounted. In the embodiment according to 10 are attachment parts 13 in the form of clamp devices 13A thereby with the circuit board 12 connected to that pins 136 in associated contact openings 123 (please refer 9 and 10 to the) and with the PCB 12 For example, be soldered so that an electrical and mechanical connection with the circuit board 12 is created. Other attachments 13 on the other hand (in the embodiment according to FIG 10 blind members 13D) are non-positively or positively with the circuit board 12 connected.

Such attachment parts 13 wise, like this 3 and 4 in synopsis with 11 to 15 it can be seen, engaging shots 132 at jetties 131 have, with which each attachment part 13 on an associated side edge 121 . 122 the circuit board 12 can be plugged, as for example, from the transition from 11 towards 12 is apparent. At the attachment part 13 is with a fixing nose 137 shaped, which causes a frictional or positive connection when applying.

In the embodiment according to 11 and 12 for example, the associated page edge 121 . 122 the circuit board 12 clamped in the engagement shots 132 absorbed by the fact that the fixing noses 137 the engaging shots 132 (under slight deformation) pressing against the circuit board 12 Press and thus produce a positive connection.

In the embodiment according to 13 to 15 however, the fixing noses engage 137 after applying the respective Ansetzteils 13 to the circuit board 12 in associated detent openings 124 the circuit board 12 a, so that a positive connection is produced, due to which the Ansetzteil 13 on the circuit board 12 is held. Every fixing nose 137 snaps when applying the attachment 13 to the assigned side edge 121 . 122 the circuit board 12 in engagement with an associated detent opening 124 the circuit board 12 so that in the attached position a latching, positive connection between the Ansetzteil 13 and the circuit board 12 is created, as is the transition from 13 towards 14 and also in 15 is apparent.

The respective attachment part 13 can thus easily on the circuit board 12 are arranged and is frictionally engaged or form-fitting with the circuit board in the attached position 12 connected.

In another embodiment may be a fixing nose 137 possibly also be waived. In this case, the engagement shots form 132 For example, a press fit with the associated side edge 121 . 122 the circuit board 12 by taking the engaging shots 132 (considered along the array direction T ) have a clear width which is smaller than the wall thickness of the circuit board 12 in the area of the associated side edge 121 . 122 so that the attachment part 13 pressing to the assigned side edge 121 . 122 is to be set and in the attached position frictionally on the side edge 121 . 122 is held.

Is that from the circuit board 12 and the attachment parts 13 then formed assembly to the housing 10 set, the position of Ansetzteile 13 on the circuit board 12 by positive engagement with the housing 10 additionally fixed, and the circuit board 12 is about the attachment parts 13 in position in the housing 10 held.

Because of attachment parts 13 in a simple manner to an associated side edge 121 . 122 the circuit board 12 can be recognized and in the attached position non-positively or positively with the circuit board 12 are connected, there is a simple assembly for the arrangement of attachment parts 13 on the circuit board 12 , In particular, the installation can be done without tools that the attachment parts 13 with her engagement shots 132 each in engagement with an associated side edge 121 . 122 the circuit board 12 brought and on the side edge 121 . 122 be plugged so that a positive or positive connection is made.

The engagement shots 132 are slit-shaped. The engagement shots 132 of each attachment part 13 are on along the insertion direction e spaced apart, across the body 130 of the attachment part 13 projecting webs 131 shaped. Like this for example 4 it can be seen, is the Ansetzteil 13 thus over two along the insertion direction e mutually offset engagement shots 132 on the associated side edge 121 . 122 the circuit board 12 fixed in a positive or positive fit.

A latching hook 137 is here in the range of each intervention recording 132 shaped. When applying the attachment 13 to the assigned side edge 121 . 122 the circuit board 12 become the catch hooks 137 (slightly) deflected and snap, after reaching the scheduled position ( 14 and 15 ), in engagement with detent openings 124 the circuit board 120 so that the attachment part 13 non-positively or positively on the circuit board 12 is fixed.

16 and 17 show another embodiment of a circuit board 12 with attached thereto Ansetzteilen 13 , The attachment parts 13 can be used as panel parts for connection devices 14 serve in the form of different connectors, but can also provide, for example, a housing element or a grid element.

One each attachment 13 has - in the illustrated embodiments - engagement shots 132 on, across the direction of insertion e , namely along the direction of arrangement T , offset to each other at the webs 131 are shaped. This allows, as in 18 to 20 is shown, two parallel to each other extending circuit boards 12 about the attachment parts 13 connect to each other so that one of the two circuit boards 12 comprehensive, preassembled unit is created, as such in the accommodation space 15 of the housing 10 can be mounted.

The attachment parts 13 are used to create the preassembled unit with their transverse to the insertion direction e , namely along the direction of arrangement T , offset from each other engagement recordings 132 non-positively or positively to associated side edges 121 . 122 the parallel aligned printed circuit boards 12 set and go in this way a frictional or positive connection with the circuit boards 12 on. In scheduled position ( 19 ) are the printed circuit boards 12 about the attachment parts 13 firmly connected to each other and thus can together in the recording room 15 of the housing 10 to be assembled. In the assembly position are the circuit boards 12 then about the attachment parts 13 in the recording room 15 of the housing 10 fixed and become both to each other and to the housing 10 resiliently held in position.

The idea underlying the invention is not limited to the preceding embodiments, but can also be realized in a completely different manner.

An electronic device of the type described here can assume very different functions, for example for controlling electrical machines, for evaluating sensor signals, for providing a power supply or the like. An electronic device of the type described here can in this case be combined with other electrical or electronic assemblies on a mounting rail, so that a complex electrical system can be created for example in a control cabinet.
