Description

The invention relates to an electronic module having a plurality of juxtaposed electronic modules, wherein the individual electronic modules each have a base housing, at least two conductor connection elements, an attachable from a first side of the base housing electronic component, in particular a relay, and a pivotally mounted on the base housing holding and Have ejector for the electronic component.

Electronic modules and electronic devices for mounting on a mounting rail have been known for many years and are used in various embodiments and for various applications. Similar to electrical terminal blocks, which are usually also snapped onto mounting rails, the electronic modules in question have at least two conductor connection elements, being used as conductor connection elements in addition to screw or spring clamp terminals for several years increasingly leg spring clamps. Leg spring terminals are often also referred to as direct terminals, as they allow the direct connection of a rigid or with a wire end ferrule provided, without the clamping point - as in tension spring terminals - must be opened before.

In contrast to conventional electrical terminal blocks, which are designed as feed-through terminals, the electronic modules in question additionally have an electronic component which is pluggable, so that it can be plugged onto the basic housing of the electronic module which then functions as a connection socket. The attachable electronic component may in particular be a relay, so that the basic housing of the electronic module represents a relay socket. Depending on the type of electronic component used, the electronic modules can be used for different applications, for example as a coupling relay between a controller and individual field devices, as a relay for signal multiplication or as a power relay.

Initially, it has been stated that the present invention relates to an electronic assembly having a plurality of juxtaposed electronic modules. The individual electronic modules, which together form the electronics module, are usually arranged side by side on a mounting rail. The number of juxtaposed, together forming an electronic module electronic modules is basically arbitrary, the individual electronic modules may have the same type of electronic components or different electronic components depending on the application. An electronic assembly with juxtaposed electronic modules is from the DE 10 2012 015 037 A1 known. On the basic housing of the electronic modules in each case a relay is plugged, which can be electrically connected via conductor connection elements which are arranged in the respective base housing.

In order to secure a relay in a basic housing, each electronic module has a hinged on the base housing Relaishaltebügel. The Relaishaltebügel is thereby formed by means of a plugged-relay relay under crosspiece or a projection such that by pivoting the Relaishaltebügels an inserted relay can be solved by the basic housing. The relay can then be lifted and replaced easily and without effort by hand. The Relaishaltebügel thus has in addition to its holding or securing function in addition to an ejection or release function, so that it can also be referred to as a holding and ejection bracket.

In addition, the individual electronic modules each still have a plug-in module, which may be, for example, a time module, whereby the relay module can be extended to a time relay. The plug-in modules each have a smaller width than the base housing and the U-shaped Relaishaltebügel, so that a Relaishaltebügel even when plugged onto the base housing plug-in module - the plug-in module across - can be pivoted.

Overall, the reveals DE 10 2012 015 037 A1 already an electronic module or consisting of several electronic modules electronics module, which is very variable in particular by the interchangeability of the individual relays can be used, whereby the replacement of a defective relay can be done easily and therefore user friendly. In addition, connection elements of adjacent electronic modules can be bridged with one another via bridging connections formed in the basic housings, as a result of which the wiring outlay for a plurality of electronic modules arranged next to one another can be reduced.

Based on the known from this document electronic module or electronic assembly, the present invention seeks to further facilitate the operation and installation of the electronic assembly for the user.

This object is achieved with the electronics assembly described in the introduction with the features of patent claim 1 in that an adapter module is provided which has an adapter housing, a number of plug contacts corresponding to the number of electronic modules and at least one interface for connecting a cable. The individual electronic modules have mating contacts that correspond to the plug contacts and can be accessed from the first side, so that the adapter module, like the individual electronic components, can be plugged onto the basic housing from the first side. The electronic assembly consisting of a plurality of juxtaposed electronic modules thus has a common adapter module which extends over the entire width of the electronic assembly, wherein contacting all the electronic modules by plugging the adapter module via the individual formed on the adapter module plug contacts and the corresponding formed in the electronic modules mating contacts become. Preferably, the adapter module has two plug contacts per electronic module and each electronic module corresponding to two mating contacts, wherein the plug contacts may be formed as contact blades or contact pins and the mating contacts as contact sockets.

According to the invention, the adapter module has at least one interface for connecting a cable, the interface preferably being a plug or a socket, so that a cable having a corresponding socket or a corresponding plug is simply electrically and mechanically connected to the interface be connected can. The interface can be, for example, a communication interface via which the individual electronic modules contacted via the adapter module can be easily configured and activated.

According to the invention, the adapter module furthermore has at least one pivotably mounted ejection lever, which can be pivoted from a first position into a second position. The ejection lever acts in such a way with the adapter module facing first sides of the main body of an electronic module or the basic housing of two adjacent electronic modules together that the adapter module is lifted or lifted by operating the eject lever of the basic housings of the electronic modules. In the first position of the eject lever, the adapter module is completely plugged onto the electronic modules and the individual plug contacts contact the associated mating contacts of the electronic modules. In the second position of the ejection lever, the plug connection between the adapter module and the electronic modules is so far solved that a removal of the adapter module from the electronic module or from the juxtaposed basic housings of the individual electronic modules is easily possible. Preferably, the electrical contact between the individual plug contacts and the mating contacts is separated. The fact that the adapter module has at least one ejection lever, the removal of the pluggable adapter module is facilitated by the electronics assembly, but the adapter module is still mechanically connected to the basic housings, so that the adapter module does not fall down unintentionally.

If the electronic assembly according to the invention has only a relatively small number of electronic modules arranged side by side, for example four electronic modules, then it may be sufficient if the adapter module, which then has the width of four electronic modules arranged next to one another, has only one ejection lever. This is then preferably arranged in the middle, between the two middle electronic modules associated plug contacts to allow a possible tilt-free and only a relatively small force requiring releasing the adapter module of the main housings of the electronic modules.

In particular, however, if the electronic module has a larger number of juxtaposed electronic modules, for example, six or eight electronic modules are arranged side by side, the adapter module preferably has two ejector, which are then arranged in each case in the vicinity of the external electronics modules associated plug contacts of the adapter module. In an electronic assembly with a total of eight juxtaposed electronic modules, the one ejector lever, for example between the first electronic module and the second electronic module associated plug contacts and the second ejection lever between the seventh electronic module and the eighth electronic module associated plug contacts can be arranged. The arrangement of two ejection levers reduces the risk that tilting occurs when the adapter module is detached from the electronics module, which would make it more difficult to pull off the adapter module and could lead to damage to individual plug contacts or individual mating contacts.

Regardless of whether the adapter module only one or two - or more - ejector has, the individual ejector lever preferably has an actuating arm and a lever arm, which are arranged at an angle α to each other. The free end of the actuating arm is designed as an operating portion and the free end of the lever arm is formed as a bearing portion with which the ejection lever is pivotally mounted in the adapter housing. The actuating portion may have such a shape and size that it can be easily and conveniently operated with one finger. The ejection lever can be pivoted by exerting a force on the actuating portion about the rotational axis formed in the adapter housing from its first position to its second position. Preferably, the angle α between the actuating arm and the lever arm about 70 ° - 110 °, in particular about 80 ° - 100 °, so that the actuating arm and the lever arm are approximately perpendicular to each other.

In the adapter module, a printed circuit board is preferably arranged, on which, depending on the application, different electronic components can be arranged. In principle, in each case the same electronic components can be provided in the adapter module for all assigned electronic modules be. In addition, however, there is also the possibility that different electronic modules are assigned to different electronic components. For example, different time modules assigned to the individual electronic modules may be arranged in the adapter module. The components associated with the respective electronic module are electrically connected to the electronic module via the plug contacts of the adapter module assigned to the electronic module and the mating contacts arranged in the electronic module. For individual control of the individual electronic components thus only a corresponding cable must be connected to the interface of the common adapter module.

In addition, the adapter module preferably also has a power supply connection. Different types of conductor connection elements can be used for connecting electrical lines to the voltage supply connection. Both the adapter module and the electronic components mounted on the individual electronic modules can be supplied with the required voltage via the power supply connection. In practice, the individual basic housing with the plugged electronic modules are often mounted on a mounting rail in a cabinet or in another place where the connection of electrical wiring is relatively difficult due to the limited space. Here, in the case of the electronic assembly according to the invention, it is possible to connect a cable to the interface or the electrical lines to the voltage supply connection even before the adapter module is plugged in, so that the simple and quick connection of the individual electronic modules plugged onto the basic housing is only possible the adapter module must be plugged.

According to a preferred embodiment of the electronic assembly according to the invention, the individual holding and ejection stirrups of the electronic modules each have two longitudinal legs and a cross leg connecting the longitudinal legs, so that the holding and ejection stirrups are substantially U-shaped. The holding and ejection stirrups are pivotally mounted with the longitudinal legs on the individual base housings, while the transverse legs in the secured state of the electronic components above the top of the electronic components are arranged. Such U-shaped holding and ejector are basically already known, for example from the DE 10 2012 015 037 A1 ,

In the electronic module according to the invention recesses are formed in the adapter module, which are arranged corresponding to the longitudinal legs of the holding and ejection stirrups, so that the longitudinal legs can partially engage in the recesses when the holding and ejection stirrup are pivoted into their ejection position. The formation of the recesses in the adapter module makes it possible that the holding and ejector can be pivoted into its ejection position even when the adapter module is attached in the longitudinal direction of the base housing to the electronic modules adjacent to the basic housing. Due to the configuration of the recesses in the adapter module, an actuation of the individual holding and ejection stirrups is thus not impaired even if the adapter module is plugged onto the electronic modules from the same side in the vicinity of the electronic components.

So that at the same time the two holding and ejection brackets of two juxtaposed electronic modules can be pivoted into their ejection position, the width of the recesses is preferably at least twice as large as the thickness of a longitudinal leg of a holding and ejection bracket. As a result, two longitudinal legs of two adjacent holding and ejection stirrups can be pivoted into a recess at the same time.

According to a further advantageous embodiment of the electronic assembly according to the invention, the adapter module has a number corresponding to the number of electronic modules number of fastening webs, to which in the basic housings of the electronic modules corresponding mounting recesses are formed. The fastening webs and the corresponding mounting recesses serve to improve the mechanical attachment of the adapter module on the basic housings, even if already by the formation of the plug contacts, such as contact blades, and the mating contacts corresponding thereto in addition to the electrical connection and a mechanical attachment between the adapter module and the Electronic modules can be achieved.

In order to ensure that it does not come to an unwanted loosening or loosening of the adapter module of the electronic modules, even with vibration or shock, in addition preferably a locking connection between at least one fastening web and at least one mounting recess is formed. With the guaranteed by the locking connection solid and durable mechanical connection at the same time the security of the electrical connection between the individual plug contacts and the individual mating contacts is increased.

If the adapter module has two ejection levers which are arranged in the vicinity of the outer plug contacts, then it is advantageously provided that only one latching connection is formed between the outer fastening webs and the corresponding mounting recesses, while between the remaining fastening webs arranged therebetween and the remaining fastening recesses no locking connection is provided. In an electronic assembly with, for example, eight electronic modules arranged side by side, not eight but only two locking connections are then realized, namely only between the two outer fastening webs and mounting recesses in the two outer electronic modules. The formation of the locking connection only with the outer fastening webs ensures a sufficiently secure locking between the adapter module and the electronic assembly, without the force required to release the locking connection by means of the ejection lever is too large.

The latching connection between the adapter module and the electronics module or the electronic modules described above can be particularly easily realized that in each case at least one latching hook is formed in the mounting recesses in the basic housings. The mounting recesses in the individual, juxtaposed basic housings are thus all the same. In contrast, only at certain, preferably on the two outer mounting webs of the adapter module at least one locking lug corresponding to the latching hook is arranged. The fact that the mounting recesses in the base housings each have at least one, preferably two opposing latching hooks, the user does not have to pay attention to what position the individual electronic modules within the electronics assembly arranged are to reach the latching with the adapter module. Characterized in that only at certain, preferably formed on the two outer fastening webs to the locking hooks locking lugs, a latching connection is realized only between these fastening webs and the associated mounting recesses. Since the remaining fastening webs have no latching noses, no latching connection is realized between these fastening webs and the associated fastening recesses, even if the associated fastening recesses each have at least one latching hook.

Previously, it has been stated that the connector between the adapter module and the electronic modules in the second position of the eject lever is so far solved that a removal of the adapter module from the electronics assembly or from the juxtaposed basic housings of the individual electronic modules is easily possible, the adapter module but still mechanically connected to the basic housings, so that the adapter module does not fall down unintentionally. Preferably, the ejection lever and the latching connection formed between a fastening web and a fastening recesses are matched to one another in such a way that the ejection lever interacts with the first module of the basic housing of an electronic module facing the adapter module or the basic housing of two adjacent electronic modules in such a way that in the second position of the ejection lever Detent connection between the adapter module and the at least one electronic module is solved, the adapter module is still connected to the at least one electronic module. The mechanical connection between the adapter module and the electronic modules can be achieved in that the fastening webs of the adapter module are still partially inserted into the corresponding mounting recesses even when the locking connection is released. Characterized in that the latching connection is released when the ejection levers are pivoted to the second position, the adapter module can be easily removed from the basic housings.

According to a further advantageous embodiment of the invention, the adapter module has a plurality of display elements, in particular a plurality of LEDs, wherein each electronic module is associated with a display element. The adapter module thus has at least one of the number of electronic modules corresponding Number of display elements. The display elements assigned to the individual electronic modules preferably serve to indicate whether the prescribed voltage is applied to the respective plug contacts.

So that the state of the individual display elements can be quickly and easily recognized by a user even if the individual holding and ejection stirrups are pivoted into their ejection position, an opening or a window is preferably formed in the transverse limbs of the individual holding and ejection stirrups. This ensures that the individual display elements can be reliably detected even when the individual holding and ejection stirrups are in their ejection position, in which the transverse legs overlap the display elements.

In particular, there are a variety of ways to design and further develop the electronic assembly according to the invention.

Two sectional views through two electronic modules with plugged adapter module, once in the locked state and once in the unlocked state.

Fig. 1 shows a perspective view of an electronic assembly 1 according to the invention, which has eight juxtaposed electronic modules 2, wherein the individual electronic modules 2 each have a base housing 3 with a plurality of conductor connection elements 4 arranged therein. In the longitudinal direction L of the individual electronic modules 2, in each case a relay 5 as an electronic component is plugged onto the basic housing 3 from a first side, the upper side 3 a, approximately in the middle region of the individual electronic modules 2. In the illustrated embodiments, the individual relays 5 each have the same dimensions, as in particular Fig. 1 and 2 is apparent. Independently of this, however, different relays with different dimensions, in particular with different heights, can be plugged onto the basic housing 3.

At the individual base housings 3, a holding and ejection bracket 6 is pivotally mounted, with which the individual relay 5 in a first position of the holding and ejection bracket 6 (FIG. Fig. 3a ) secured in the individual basic housings 3 and in a second position of the holding and ejection bracket 6 (FIG. Fig. 3b ) can be solved by the individual basic housings 3. In the second position of the holding and ejection bracket 6 is pivoted to one side so that the associated relay 5 of the basic housing 3 can be easily - upwards - deducted.

In addition to the eight electronic modules 2, the electronic module 1 also has a common adapter module 7 which is plugged onto the eight electronic modules 2 or the basic housing 3 arranged next to one another. The adapter module 7 that in the Figures 5 and 6 is shown separately, has an adapter housing 8 and a number corresponding to the number of electronic modules 2 number of plug contacts 9 and an interface 10. The width of the adapter module 7 corresponds to the width of the electronic module 1, so that an adapter module 7 is provided for a predetermined number of electronic modules 2.

Out Fig. 6 It can be seen that the plug contacts 9 are arranged in pairs, wherein each two formed as a contact blades plug contacts 9 are assigned to an electronic module 2. Corresponding to the plug-in contacts 9, the individual electronic modules 2 each have two corresponding mating contacts 11 which are accessible from the upper side 3 a of the base housing 3, so that the adapter module 7 can be plugged from the same direction as the individual relays 5 onto the electronic modules 2 arranged side by side , The mating contacts 11 may be formed, for example, as contact tulips or contact sockets. When the adapter module 7 is plugged in, the individual relays 5 of the individual electronic modules 2 can be simply controlled via the interface 10 without having to electrically connect each relay 5 individually via an electronic module 2. The interface 10 is formed as a socket, so that a cable with a corresponding connector can be easily and quickly connected electrically and mechanically to the interface.

The adapter module 7 also has two ejection levers 12, which are each arranged in the vicinity of the outer plug contacts 9. The ejector 12 are arranged in the adapter housing 8, that the ejector 12 are in the plugged state of the adapter module 7 each centrally between two electronic modules 2. As from the two representations according to Fig. 4 it can be seen, an ejection lever 12 has an actuating arm 13 and a lever arm 14, which are arranged at an angle α to each other, which is approximately 90 ° in the illustrated embodiment. The free end of the actuating arm 13 is formed as an actuating portion 15 having an enlarged compared to the cross section of the actuating arm 13 surface, so that the ejector lever 12 by a user simply by pressing a finger on the top of the actuating portion 15 from its first position ( Fig. 4a ) into its second position ( Fig. 4b ) can be pivoted. The free end of the lever arm 14 is formed as a bearing portion 16 which engages around a bearing pin 17 formed in the adapter housing 8.

If the eject lever 12 from the in Fig. 4a shown in the first position in which the adapter module 7 is completely attached to the individual electronic modules 2 and the individual basic housing 3, in the in Fig. 4b pivoted second position shown, the lever arm 14 cooperates with the top 3a of two adjacent base housing 3 together that the adapter module 7 is lifted from the basic housing 3. In this case, the adapter module 7 is lifted far enough from the basic housings 3 that a locking connection formed between the adapter housing 8 and the basic housings 3 is released, so that the adapter module 7 can be easily removed by a user. However, the adapter module 7 is still mechanically connected to the basic housings 3, so that it does not accidentally fall off the electronic assembly.

In Fig. 3 the electronics assembly 1 is shown from the side, wherein the holding and ejection bracket 6 in Fig. 3a in its the associated relay 5 fixing holding position and in Fig. 3b in which the relay 5 is shown by the housing 3 lifting ejection position. The individual holding and ejection bracket 6 are as out Fig. 1 it can be seen, in each case approximately U-shaped, wherein the individual holding and ejection stirrups 6 each have two longitudinal limbs 18 and a transverse limb 19 connecting the two longitudinal limbs 18. Thus, the individual holding and ejection bracket 6 can be pivoted even when plug adapter module 7 in its second position, the adapter module 7 has a corresponding number of recesses 20, in which the longitudinal leg 18 partially engage when the holding and ejection bracket 6 in the second position, ie the ejection position according to Fig. 3b are pivoted.

The width of the individual recesses 20 is at least twice as large as the thickness of a longitudinal leg 18 of a holding and ejection bracket 6. This also adjacent juxtaposed holding and ejection bracket 6 can be simultaneously pivoted into its ejection position, as in the in Fig. 1 illustrated electronics module 1 in all eight holding and ejection stirrups 6 of the eight juxtaposed electronic modules 2 is the case. The recesses 20 are arranged in the adapter housing 8, that the Aussparrungen 20 are in the plugged state of the adapter module 7 respectively centrally between two electronic modules 2. In a recess 20, the two juxtaposed electronic modules 2 is assigned, then the right longitudinal leg 18 of the first, left holding and ejection bracket 6 and the left longitudinal leg 18 of the second, right holding and ejection bracket 6 can then simultaneously engage when both holding and ejection bracket. 6 be given away in the ejection position.

Due to the design of the recesses 20 in the adapter module 7, the adapter module 7 can be arranged in the longitudinal direction L of the individual electronic modules 2 immediately adjacent to the individual relays 5, wherein nevertheless the possibility exists that the individual holding and ejection bracket 6 are pivoted into their ejection position , The pivoting of the holding and ejection bracket 6 is thus not hindered by the adjacent to the relay 5 adapter module 7.

From the representation of the adapter module 7 of the plugged-in state, the relay 5 facing back according to Fig. 6 It can be seen that the adapter module 7 has two plug contacts 9 designed as contact blades per electronic module 2. Between each pair of plug contacts 9 each have a fastening web 21 is arranged, wherein a fastening web 21 and two plug contacts 9 are part of a connector housing 8 formed on the connector portion 22. In an electronic module 1 with eight electronic modules 2 arranged side by side, the adapter module 7 thus has eight plug sections 22, wherein the recesses 20 in the adapter housing 8 are arranged between the individual plug sections 22.

The FIGS. 7a and 7b each show a sectional view along the in Fig. 2 drawn line VII - VII, wherein in the Fig. 7a and 7b only the two in Fig. 2 left arranged electronic modules 2 and the corresponding part of the adapter module 7 is shown. The other six electronic modules 2 and the remaining part of the adapter module 7, however, are in Fig. 7 not shown. For each connector portion 22, a corresponding recess 23 is formed in the base housing 3 of the individual electronic modules 2, as shown Fig. 7 is apparent. In addition, 21 corresponding mounting recesses 24 are formed in the individual base housings 3, which in the mounting direction, ie viewed from the top surface 3a in the interior of the base housing 3 to the Connect recesses 23. In the plugged state of the adapter module 7, the individual plug sections 22 are thus arranged in the individual recesses 23 and the individual fastening webs 21 in the individual fastening recesses 24, the individual plug contacts 9 contacting the corresponding mating contacts 11.

Out Fig. 7 is also apparent that in each case two latching hooks 25 are formed in the mounting recesses 24, which together with two latching noses 26 which are arranged on a fastening web 21, form a latching connection. While in each case electronic modules 2 each two latching hooks 25 are formed in the mounting recesses 24, have only the two outer mounting webs 21 of the adapter module 7 - in Fig. 7a and 7b in each case only the left attachment web 21 - to the latch hook 25 corresponding locking lugs 26. The fact that 25 corresponding locking lugs 26 are formed only on the two outer fastening webs 21 and not on all fastening webs 21 to the formed in the mounting recesses 24 of all basic housing 3 locking hooks, a sufficiently secure locking of the adapter module 7 on the basic housings 3 is ensured without the effort required to release the locking connection is too great. The release of the latching connection is further facilitated and tilting of the adapter housing 8 prevents the two ejection levers 12 are arranged in the vicinity of the two mounting webs 21, on which the locking lugs 26 are formed.

In Fig. 7a the adapter module 7 is shown in the locked state, in which the ejection lever 12 thus in the in Fig. 4a is shown in the first position shown. The locking lugs 26 of the left fastening web 21 are thus arranged below the latching hooks 25, whereby the fastening web 21 is latched in the mounting recess. In contrast, in the illustration according to Fig. 7b the latching between the latching hooks 25 of the fastening recess 24 and the latching lugs 26 of the left fastening web 21 is released, since the latching lugs 26 of the left fastening web 21 are arranged above the latching hooks 25. By pivoting the two eject lever 12 from its first position to its second position according to Fig. 4b is the adapter module 7 only raised so far that the locking connection is released, while the fastening webs 21 with their free end still in the mounting recesses 24 engage, so that the adapter housing 8 is still mechanically connected to the basic housings 3.

In particular, from the perspective view of the adapter module 7 according to Fig. 5 it can be seen that the adapter module 7 in addition to the interface 10 still has a power supply terminal 27. In addition, a plurality of LEDs 28 are provided, wherein in each case one LED 28 is assigned to an electronic module 2. The individual LEDs 28 are preferably used to indicate whether the prescribed voltage is applied to the respective plug contacts 9. Thus, the state of the individual LEDs 28 can be detected easily and quickly by a user even if the holding and ejection bracket 6 according to the Fig. 1 and 2 are in their ejection position, in each case a recess 29 is formed in the transverse legs 19 of the individual holding and ejection bow 6, which is located above the associated LED 28 in the pivoted state of the holding and ejection bracket 6.
