Definitions
- the invention relates to a holding frame for connector modules according to the preamble of independent claim 1.
- Such holding frames are used to hold connector modules, the holding frame being equipped with various connector modules and then inserted into a connector housing and screwed to it.
- the holding frame must be mechanically stable in order to be able to withstand the plugging and pulling forces that occur when joining or disconnecting the plug connection.
- the holding frame consists of two halves that are connected to each other via a joint. Snap hooks of the connector modules engage in recesses in the side surfaces of the respective half.
- the joint or the end joints are arranged in the fastening ends of the holding frame.
- the holding frame of the DE 197 07 120 C1 has no clearly defined open position for fitting the holding frame with connector modules. This sometimes results in a somewhat bulky installation, especially for inexperienced people.
- the holding frame If the holding frame is successfully fitted with connector modules, it must be brought into a closed state or into a closed position so that the connector modules are fixed. There is no fixed closed state for the closed state of the holding frame of the prior art, so that the holding frame can open accidentally, as a result of which the modules can fall out of their anchoring.
- a purely articulated connection does not always result in a defined electrical contact between the halves of the holding frame. As a result, reliable use of the holding frame for earthing purposes cannot be guaranteed.
- the DE 20 2013 103 611 U1 shows a holding frame for connector modules, which is formed from two halves.
- the halves each have two flat contact areas. If the contact areas are in contact, the holding frame is closed and the connector modules located in it are fixed captively. At the contact areas, the halves can be reversibly fixed together using a screw connection.
- the CN 204 205 152 U shows a holding frame for connector modules.
- the holding frame consists of two halves, which are connected to each other at the respective ends via spiral springs. The halves are drawn longitudinally towards each other by the spiral springs.
- the object of the invention is to propose a holding frame that is easy to handle and versatile.
- the holding frame proposed here is intended for fitting with so-called connector modules and for installation in a connector housing or a device wall.
- the holding frame has two interconnectable halves, a first half and a second half, and at least one first spring element.
- the halves each have side parts.
- the long sides of the halves form a parting plane.
- the halves can make an angle ⁇ to one another along this plane of separation. If the angle is less than 180 °, the holding frame is moved into an open position. To do this, work must be carried out against the spring force of the spring element.
- the first spring element exerts a restoring force on the halves, as a result of which the side parts of the holding frame strive in a substantially parallel alignment with one another. In this case, the angle mentioned above is approximately 180 °.
- the side parts of the halves are aligned essentially parallel to one another by the restoring force.
- the restoring force acts on the halves in the direction of the closed position.
- the holding frame can be opened so that connector modules can be inserted into it.
- the side parts are brought into an angular position (a less than 180 °) to each other.
- the side parts are back in one parallel position to each other. This rotary movement, supported by the spring element, does not cause hooking or canting in the connector modules used.
- the halves are aligned in the closed position by the restoring force.
- the halves can be aligned and fixed to one another in at least two positions.
- the holding frame can be fixed with the fixing element either in an open position or in a closed position. In the open position, the holding frame can be equipped with connector modules. In the closed position, the connector modules can no longer slip or fall out.
- the spring element has an omega-shaped or an essentially omega-shaped basic shape, with laterally projecting holding arms being molded onto the basic shape.
- the spring element is fixed to the halves via the holding arms.
- An upwardly directed fixing element can also be molded onto the basic shape.
- the fixing element and the laterally projecting holding arms lie in one plane and are oriented approximately perpendicular to one another.
- Such a spring element can be produced inexpensively from a sheet metal material using stamping and bending technology.
- Two detent springs are advantageously formed on the fixing element of the spring element.
- Two outward-facing recesses are made in each end of each half of the holding frame.
- a catch spring can be engaged in the two recesses of the first half and the other catch spring in the two recesses of the second half, as a result of which the holding frame can be fixed in an open position or in a closed position.
- This type of fixation is technically particularly easy to implement and particularly user-friendly.
- the halves each have a cutout on the end face.
- the recesses are essentially mirror-symmetrical and directed towards one another.
- the cutouts together form a receptacle in which the spring element is fixed.
- the curved basic shape of the spring element takes over an articulated connection of the two halves, as is complexly realized in the prior art by a joint head with a corresponding joint receptacle.
- the articulated connection proposed here is much easier to establish.
- the holding frame preferably has a second spring element and the first spring element and the second spring element are of identical construction.
- the locking plates are located on the respective end faces of the joined halves. The function of the holding frame is significantly more stable thanks to two locking plates.
- the alignability of the holding frame is achieved by the articulated connection of the two halves of the holding frame.
- the fixability is achieved by the spring element.
- the interaction between articulated connection and fixability in two positions makes the holding frame particularly user-friendly.
- the spring element proposed here takes on a double function by ensuring the articulated connection and the fixation.
- the two halves are reliably brought into electrical contact with one another via the spring element. This happens on the one hand via the spring element itself, provided that it is made of an electrically conductive material. In addition, the pre-tensioning of the spring element presses the joint head of one half into the joint holder of the other half, which creates a reliable electrical contact.
- open or closed state and open or closed position are used synonymously.
- the Figure 1 shows two halves 4, 5, a first half 4 and a second half 5, of an articulated frame, the long sides of the halves 4, 5 form a separation level.
- the halves can make an angle ⁇ to one another along this plane of separation.
- the viewer's gaze is directed towards the respective end faces, a first end face 6, 6 'and a second end face 13, 13', of the holding frame 1.
- open position it is meant that the halves 4, 5 are at an angle ⁇ not equal to 180 ° to one another along the dividing line.
- the angle is preferably between 130 ° to 170 °.
- An angle between 155 ° and 165 ° has proven to be particularly advantageous.
- the connector modules 19 can be inserted particularly easily into the holding frame 1.
- the halves 4, 5 form an angle of approximately 180 ° or exactly 180 ° to one another. The halves 4, 5 are thus parallel to each other in the closed position.
- the halves 4, 5 each have a recess on the end face, a first recess 2, 2 'and a second recess 3, 3', the recesses 2, 2 ', 3, 3' each forming a receptacle 10, 10 ' , in which the spring element 7, 7 'is fixed.
- the holding frame 1 shown here has a receptacle 10, 10 'on both sides for a spring element 7, 7'.
- Inwardly directed teeth 17 are formed in the cutouts 2, 2 ', 3, 3', with which the holding arms 9, 9 'of the spring element 7, 7' can be clamped. As a result, the spring element 7, 7 'is held in the receptacle 10, 10'.
- FIG. 5 and 6 perspective views of the spring element 7 are shown, which is fixed in the receptacle 10 of the holding frame 1.
- the spring element 7 has an essentially omega-shaped basic shape 8. At the basic shape 8 are laterally protruding Holding arms 9, 9 'formed. At the end, the holding arms 9, 9 'are bent downwards.
- An upwardly directed fixing element 11 is formed on the basic shape 8. On the fixing element 11 of the spring element 7, two external detent springs 12 are formed approximately in the middle.
- Each end face 6, 6 ', 13, 13' of the halves 4, 5 each has two outwardly directed recesses 14, 14 ', 15, 15', an inner recess 14, 14 'and an outer recess 15, 15' ,
- the spring element 7 is shaped such that the detent springs 12 can engage in the recesses 14, 14 ', 15, 15' of the halves 4, 5. If the catch springs 12 are in the inner recesses 14, 14 ', the holding frame 1 is fixed in a closed position. If the detent springs 12 are in the outer recesses 15, 15 ', the holding frame 1 is fixed in an open position and can be equipped with connector modules 19.
- an actuating piece 16 is formed on the fixing element 11.
- the detent spring 12 can be pulled away from the end faces 6, 6 ', 13, 13' of the halves 4, 5, as a result of which the detent springs 12 are pulled out of the engagement of the recesses 14, 14 ', 15, 15'. Then the halves 4, 5 can be brought into another position relative to one another.
- the omega-shaped basic shape 8 is designed to be resilient and takes over the articulated connection of the halves 4, 5. The restoring force of this basic shape 8 ensures that the halves 4, 5 are in principle pressed into the closed position of the holding frame 1.
- Connector modules 19 have long been known and for example in the DE 197 07 120 C1 described.
- the connector modules 19 are provided with projecting, approximately rectangular holding means 20 and spring-elastic latching hooks 21.

- the holding frame 1 is brought into an open position as described above, so that the connector modules 19 can be used.
- the latching hooks 21 first grip under the lower edges of the side parts 22 of the halves 4, 5 when they are inserted.
- the frame halves 4, 5 are brought into a closed position as described above, the holding means 20 entering the recesses 23 and causing the connector modules 19 to be securely and positively held in the holding frame 1.
- the holding frame 1 has an earthing bush 24, into which a pin (not shown) of an opposite holding frame (not shown) can engage.
- FIG 7 an alternative variant of the spring element 7 'is shown.
- the spring element 7 'shown here dispenses with a fixing element with which the holding frame 1 can be fixed in two positions.
- the holding frame 1 is held in a closed position only by the restoring force generated by the spring element 7 '. This is enough however, from the fact that the connector modules 19 do not fall out of the holding frame 1 after insertion.
- work In order to open the holding frame 1, work must be carried out against the restoring force of the spring element 7 '.
- the viewer's gaze is directed towards the respective end faces 6, 6 ', 13, 13' of the holding frame 1.
- the holding frame 1 can be bent into an open position against a spring force, which is provided by the spring element 7 'and is symbolized by the double arrow 25.
- open position it is meant that the halves 4, 5 are at an angle ⁇ not equal to 180 ° to one another along the dividing line.

Description
Die Erfindung geht aus von einem Halterahmen für Steckverbindermodule nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention relates to a holding frame for connector modules according to the preamble of independent claim 1.
Derartige Halterahmen dienen zur Halterung von Steckverbindermodulen, wobei der Halterahmen mit verschiedenen Steckverbindermodulen bestückt und anschließend in ein Steckverbindergehäuse eingesetzt und mit diesem verschraubt wird. Dabei muss der Halterahmen mechanisch stabil sein, um den auftretenden Steck- und Ziehkräften beim Zusammenfügen bzw. Trennen der Steckverbindung standhalten zu können.Such holding frames are used to hold connector modules, the holding frame being equipped with various connector modules and then inserted into a connector housing and screwed to it. The holding frame must be mechanically stable in order to be able to withstand the plugging and pulling forces that occur when joining or disconnecting the plug connection.

Der Halterahmen der
Bei erfolgreicher Bestückung des Halterahmens mit Steckverbindermodulen muss dieser in einen geschlossen Zustand beziehungsweise in eine geschlossene Position gebracht werden, damit die Steckverbindermodule fixiert sind. Für den geschlossenen Zustand des Halterahmens des Standes der Technik gibt es keinen fixierten geschlossenen Zustand, so dass sich der Halterahmen versehentlich öffnen kann, wodurch die Module aus ihrer Verankerung fallen können.If the holding frame is successfully fitted with connector modules, it must be brought into a closed state or into a closed position so that the connector modules are fixed. There is no fixed closed state for the closed state of the holding frame of the prior art, so that the holding frame can open accidentally, as a result of which the modules can fall out of their anchoring.
Durch eine reine gelenkige Verbindung besteht nicht immer ein definierter elektrischer Kontakt zwischen den Hälften des Halterahmens. Dadurch kann ein zuverlässiger Einsatz des Halterahmens zu Erdungszwecken nicht gewährleistet werden.A purely articulated connection does not always result in a defined electrical contact between the halves of the holding frame. As a result, reliable use of the holding frame for earthing purposes cannot be guaranteed.

Insgesamt ist der Bestückungsprozess der
Die Aufgabe der Erfindung besteht darin einen Halterahmen vorzuschlagen der einfach handhabbar und vielseitig einsetzbar ist.The object of the invention is to propose a holding frame that is easy to handle and versatile.
Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The object is achieved by the characterizing features of independent claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Der hier vorgeschlagene Halterahmen ist zur Bestückung mit so genannten Steckverbindermodulen und zum Einbau in ein Steckverbindergehäuse beziehungsweise eine Gerätewand vorgesehen. Der Halterahmen weist zwei miteinander verbindbare Hälften, eine erste Hälfte und eine zweite Hälfte, und zumindest ein erstes Federelement auf. Die Hälften weisen jeweils Seitenteile auf.The holding frame proposed here is intended for fitting with so-called connector modules and for installation in a connector housing or a device wall. The holding frame has two interconnectable halves, a first half and a second half, and at least one first spring element. The halves each have side parts.
Die Längsseiten der Hälften bilden eine Trennungsebene aus. Entlang dieser Trennungsebene können die Hälften einen Winkel α zueinander einnehmen. Ist der Winkel kleiner 180° wird der Halterahmen in eine offene Position überführt. Hierzu muss entgegen einer Federkraft des Federelements gearbeitet werden. Das erste Federelement übt eine Rückstellkraft auf die Hälften aus, wodurch die Seitenteile des Halterahmens in eine im Wesentlichen parallele Ausrichtung zueinander streben. In diesem Fall ist der oben erwähnte Winkel in etwa 180°.The long sides of the halves form a parting plane. The halves can make an angle α to one another along this plane of separation. If the angle is less than 180 °, the holding frame is moved into an open position. To do this, work must be carried out against the spring force of the spring element. The first spring element exerts a restoring force on the halves, as a result of which the side parts of the holding frame strive in a substantially parallel alignment with one another. In this case, the angle mentioned above is approximately 180 °.
Wie bereits oben erwähnt, werden die Seitenteile der Hälften durch die Rückstellkraft im Wesentlichen parallel zueinander ausgerichtet. Die Rückstellkraft wirkt in Richtung der geschlossenen Position auf die Hälften.As already mentioned above, the side parts of the halves are aligned essentially parallel to one another by the restoring force. The restoring force acts on the halves in the direction of the closed position.
Der Halterahmen kann geöffnet werden, damit Steckverbindermodule darin eingesetzt werden können. Zum Öffnen des Halterahmens werden die Seitenteile in eine Winkelstellung (a kleiner 180°) zueinander gebracht. Beim Schließen des Halterahmens werden die Seitenteile wieder in eine parallele Position zueinander zurückgeführt. Diese rotative Bewegung, unterstützt durch das Federelement, verursacht keine Verhakungen bzw. Verkantungen bei den eingesetzten Steckverbindermodulen. Die Hälften werden durch die Rückstellkraft in die geschlossene Position ausgerichtet.The holding frame can be opened so that connector modules can be inserted into it. To open the holding frame, the side parts are brought into an angular position (a less than 180 °) to each other. When closing the holding frame, the side parts are back in one parallel position to each other. This rotary movement, supported by the spring element, does not cause hooking or canting in the connector modules used. The halves are aligned in the closed position by the restoring force.
Wenn das Federelement zusätzlich ein Fixierelement aufweist, sind die Hälften in zumindest zwei Positionen zueinander ausrichtbar und fixierbar. Der Halterahmen kann mit dem Fixierelement wahlweise in einer offenen Position oder in einer geschlossenen Position fixiert werden. In der offenen Position kann der Halterahmen mit Steckverbindermodulen bestückt werden. In der geschlossenen Position können die Steckverbindermodule nicht mehr verrutschen oder hinausfallen.If the spring element additionally has a fixing element, the halves can be aligned and fixed to one another in at least two positions. The holding frame can be fixed with the fixing element either in an open position or in a closed position. In the open position, the holding frame can be equipped with connector modules. In the closed position, the connector modules can no longer slip or fall out.
Das Federelement weist eine Omega-förmige beziehungsweise eine im Wesentlichen Omega-förmige Grundform auf, wobei an der Grundform seitlich abstehende Haltearme angeformt sind. Über die Haltearme ist das Federelement an den Hälften fixiert. An der Grundform kann außerdem ein nach oben gerichtetes Fixierelement angeformt sein. Das Fixierelement und die seitlich abstehenden Haltearme liegen in einer Ebene und sind in etwa senkrecht zueinander ausgerichtet. Ein solches Federelement ist kostengünstig aus einem Blechmaterial in Stanz-Biegetechnik herstellbar.The spring element has an omega-shaped or an essentially omega-shaped basic shape, with laterally projecting holding arms being molded onto the basic shape. The spring element is fixed to the halves via the holding arms. An upwardly directed fixing element can also be molded onto the basic shape. The fixing element and the laterally projecting holding arms lie in one plane and are oriented approximately perpendicular to one another. Such a spring element can be produced inexpensively from a sheet metal material using stamping and bending technology.
Vorteilhafterweise sind an dem Fixierelement des Federelements zwei Rastfedern angeformt. In eine Stirnseite jeder Hälfte des Halterahmens sind jeweils zwei nach außen gerichtete Ausnehmungen eingebracht. Eine Rastfeder ist in die zwei Ausnehmungen der ersten Hälfte und die andere Rastfeder in die zwei Ausnehmungen der zweiten Hälfte eingreifbar, wodurch der Halterahmen in einer offenen Position oder in einer geschlossenen Position fixierbar ist. Diese Art der Fixierung ist technisch besonders einfach realisierbar und besonders bedienerfreundlich.Two detent springs are advantageously formed on the fixing element of the spring element. Two outward-facing recesses are made in each end of each half of the holding frame. A catch spring can be engaged in the two recesses of the first half and the other catch spring in the two recesses of the second half, as a result of which the holding frame can be fixed in an open position or in a closed position. This type of fixation is technically particularly easy to implement and particularly user-friendly.
In einer besonders vorteilhaften Ausführungsform der Erfindung weisen die Hälften stirnseitig jeweils eine Aussparung auf. Die Aussparungen sind im Wesentlichen spiegelsymmetrisch ausgeführt und zueinander hin gerichtet. Die Aussparungen bilden zusammen eine Aufnahme, in welche das Federelement fixiert ist. In diesem Fall übernimmt die gebogene Grundform des Federelements eine gelenkige Verbindung der beiden Hälften, wie sie im Stand der Technik aufwendig durch einen Gelenkkopf mit entsprechender Gelenkaufnahme realisiert ist. Die hier vorgeschlagene gelenkige Verbindung ist deutlich einfacher herzustellen.In a particularly advantageous embodiment of the invention, the halves each have a cutout on the end face. The recesses are essentially mirror-symmetrical and directed towards one another. The cutouts together form a receptacle in which the spring element is fixed. In this case, the curved basic shape of the spring element takes over an articulated connection of the two halves, as is complexly realized in the prior art by a joint head with a corresponding joint receptacle. The articulated connection proposed here is much easier to establish.
Vorzugsweise weist der Halterahmen ein zweites Federelement auf und das erste Federelement und das zweite Federelement sind baugleich ausgeführt. Die Sperrbleche befinden sich an den jeweiligen Stirnseiten der zusammengefügten Hälften. Durch zwei Sperrbleche wird der Halterahmen in seiner Funktion deutlich stabiler.The holding frame preferably has a second spring element and the first spring element and the second spring element are of identical construction. The locking plates are located on the respective end faces of the joined halves. The function of the holding frame is significantly more stable thanks to two locking plates.
Die Ausrichtbarkeit des Halterahmens wird durch die gelenkige Verbindung der beiden Hälften des Halterahmens erreicht. Die Fixierbarkeit wird durch das Federelement erreicht. Durch das Zusammenspiel von gelenkiger Verbindung und Fixierbarkeit in zwei Positionen wird der Halterahmen besonders bedienerfreundlich. Das hier vorgeschlagene Federelement übernimmt eine Doppelfunktion, indem es die gelenkige Verbindung und die Fixierung gewährleistet.The alignability of the holding frame is achieved by the articulated connection of the two halves of the holding frame. The fixability is achieved by the spring element. The interaction between articulated connection and fixability in two positions makes the holding frame particularly user-friendly. The spring element proposed here takes on a double function by ensuring the articulated connection and the fixation.
Über das Federelement werden die beiden Hälften zuverlässig in elektrischen Kontakt zueinander gebracht. Dies geschieht zum einen über das Federelement selbst, sofern es aus einem elektrisch leitenden Material gefertigt ist. Außerdem wird durch die Vorspannung des Federelements der Gelenkkopf einer Hälfte in die Gelenkaufnahme der anderen Hälfte gedrückt, wodurch ein zuverlässiger elektrischer Kontakt entsteht.The two halves are reliably brought into electrical contact with one another via the spring element. This happens on the one hand via the spring element itself, provided that it is made of an electrically conductive material. In addition, the pre-tensioning of the spring element presses the joint head of one half into the joint holder of the other half, which creates a reliable electrical contact.
Bei der vorliegenden Erfindung werden die Begriffe offener oder geschlossener Zustand und offene oder geschlossene Position synonym verwendet.In the present invention, the terms open or closed state and open or closed position are used synonymously.
