Description

Plug connector module for connecting protection lines
Technical Field
The invention relates to a plug connector module for connecting protection lines according to the preamble of claim 1.
Background
Plug connector modules of this type comprise a housing which can be inserted in an electrically contacting manner into a receiving frame to form a plug connector assembly; a plug section arranged on the housing for plug connection with a corresponding mating plug connector; and comprises electrical contact elements arranged on the plug section for making electrical contact with a mating plug connector.
For example, such a plug connector module can be combined with a further plug connector module on a corresponding receiving frame to form a plug connector assembly, which can be used, for example, as a modular connector insert in a housing to form a plug connector. The modular combination of plug connector modules can be used to create variably configurable plug surfaces for connecting with corresponding mating plug connectors, for example for connecting electrical cables with corresponding electrical components, for example on a switchgear cabinet or electrical machine, or for electrically connecting two electrical cables to one another.
The plug connector modules referred to here are designed for connecting protection lines, also referred to as PE lines. Such a protection line serves to place the plug connector module and thus the plug connector assembly created using the plug connector module at a protection potential, corresponding to a ground potential, known in english as Protective Earth, or PE for short. With such a plug connector module, which can be attached to the receiving frame in a modular manner, the protection line can thus be connected to a plug connector assembly created using the plug connector module, so that in particular the receiving frame is also brought to a protection potential, and when connecting a plug connector created using the plug connector assembly with a mating plug connector, an electrical contact can be created with the protection potential transmitted between the plug connector and the mating plug connector.
In order to achieve a transfer of the protection potential from the plug connector module to the plug connector assembly, the plug connector module is in electrical contact with the receiving frame when the protection line is connected, so that the protection line connected to the plug connector module is electrically connected with the receiving frame. For this purpose, the housing of the plug connector module can be made of an electrically conductive material and is therefore electrically conductive. However, the plug connector module can also have contact means (in the case of an electrically insulating housing) which establish an electrical contact with the receiving frame when the plug connector module is inserted.
An electrical plug connector module for accommodation in a modular plug connector is known from DE 102013108383B 4, which has an electrically insulating housing and electrical contacts accommodated thereon. Protective contact means in the form of springs are connected with the electrical contacts and can make contact with a receiving frame into which the plug connector module can be inserted.
A plug connector module is known from DE 202015009753U 1, which has a housing formed from two housing parts. The housing may be clipped on the receiving frame to be disposed in the receiving frame.
DE 102017118719 a1 discloses an assembly of plug connector parts, in which modular contact inserts are accommodated in a holding frame. The contact insert has a plurality of insertion openings for inserting electrical conductors.
In plug connector modules of the type in question, which are used for connecting electrical lines in the form of protection lines and can be combined modularly with other plug connector modules to create a plug connector assembly, for example for use on a plug connector part for plug connection with a mating plug connector part, it is in principle necessary to be able to connect the protection lines in a simple and convenient manner and, if necessary, also to be able to re-separate them from the plug connector module.
Disclosure of Invention
The object of the invention is to provide a plug connector module for connecting protection lines, which can be combined in a variable manner with other plug connector modules and can be operated simply for connecting protection lines.
This object is achieved by a body having the features of claim 1.
Accordingly, the plug connector module has a connecting assembly to which the protective wires can be connected for electrical contact with the contact elements, and which has a spring element with clamping legs. The clamping legs are formed for acting on the protective wire in the clamped position for electrical contact and mechanical locking.
The plug connector module has a connection assembly in a spring force-fitting manner. For this purpose, the connecting assembly comprises spring elements which act with clamping legs on the protection wires attached to the plug connector module in order to electrically contact the protection wires in the connecting position and mechanically lock them on the plug connector module. A simple connection process is achieved in that, for connection to the connection assembly, the protective wires are plugged onto the connection assembly in such a way that they are effectively connected to the clamping legs and are clamped by the clamping legs, so that the protective wires are brought into electrical contact with the contact elements of the plug connector module and are mechanically locked on the plug connector module.
In conventional plug connector modules for connecting protection lines to contact elements, for example, a crimp connection is provided, but the plug connector module proposed here makes it possible to easily connect the protection lines by plugging them onto the connection assembly. The connection can be designed such that the protection line can also be released again from the connection assembly in an easy-to-handle manner. The connection assembly can be designed for connecting protection lines with different conductor cross sections. This results in a modular plug connector module which is simple and convenient to operate and which enables a secure connection of the protective wire to the plug connector assembly.
In one embodiment, the housing has an insertion opening for inserting the protective cable. In the clamping position, the clamping legs are designed to act on the protective wire inserted into the insertion opening in order to electrically contact the protective wire and mechanically lock it relative to the housing. For example, the clamping legs can be designed to press the protective wire with the uninsulated conductor end into contact with the contact section, for example in the form of a current bar, in order to establish electrical contact between the protective wire and the contact section in this way. In the connecting position, the clamping legs then preferably act on the protective wire in such a way that the protective wire is also mechanically held on the plug connector module and cannot therefore be easily removed from the connecting position, at least without adjusting the clamping legs.
The clamping legs are preferably movable from their clamping position into a release position in order to be able to simply connect the protective wire or release the connected protective wire substantially without force in such a way that the protective wire can be removed from the connecting assembly and thus separated from the plug connector module. In one embodiment, the connecting assembly has an actuating element for this purpose, which can be actuated by a user to adjust the clamping leg into the release position. The actuating element can be designed, for example, in the form of a slide which is guided on the housing in a movable manner in the guide opening. The actuating element can be moved here, for example, linearly or along a curved guide track on the housing. However, it is also conceivable and possible to design the actuating element by means of a lever, which is pivotably arranged on the housing.
The actuating element can be actuated in order to move the clamping leg into the release position. If the protective cable is to be connected to a connecting assembly, for example, the actuating element can be actuated in order to place the clamping leg in the release position. The actuating element can also be actuated when the connected protective cable is to be released in order to separate the protective cable from the plug connector module. The actuating element can be actuated by means of a tool, for example a screwdriver. However, it is also conceivable to design the actuating element in such a way that it can be actuated by the hand of the user.
In one embodiment, the actuating element is formed to act (directly) on the clamping leg or (indirectly) on a component operatively connected to the clamping leg in order to adjust the clamping leg. For example, the actuating element can press on the clamping leg in order to adjust the clamping leg from the clamping position into the release position. Alternatively, the actuating element can act, for example, on a lever arm connected to the clamping leg or also on a component formed separately from the clamping leg, for example, a sliding element operatively connected to the clamping leg.
In one embodiment, the spring element has a support leg which is connected to the clamping leg and is supported relative to the housing and to which the clamping leg can be elastically deflected. The spring element is firmly supported on the housing by means of the supporting leg and is thus held fixed relative to the housing, the clamping leg being elastically adjustable relative to the supporting leg.
The spring element can be formed, for example, integrally as a sheet metal part, for example as a stamped and bent part. The spring element is thus preferably formed integrally with the support leg, wherein the support leg can be connected to the clamping leg, for example, via a curved connecting section, and can be supported, for example, on the housing via the connecting section, for example by placing the connecting section around a housing section, so that a well-defined pivot point of the clamping leg relative to the support leg is determined.
In general, the support legs support the spring element on the housing, so that the spring element is held in a fixed manner and the clamping legs can be deflected elastically toward the support legs when the protective cable is connected. In the connected position, the clamping legs then clamp the protective wire, so that the protective wire is electrically contacted and, in addition, mechanically locked. In one embodiment, the support leg has an opening through which the clamping leg passes and into which the protective wire can be introduced for connection to the connecting assembly. If the protective cable, when connected to the connecting assembly, passes through an opening in the supporting leg through which the clamping leg also extends, the protective cable, when connected to the connecting assembly, is clamped in the opening or is electrically contacted thereby and mechanically locked. A secure hold in the connection position is achieved while at the same time a reliable electrical contact is made.
In one embodiment, the spring element is electrically connected to the contact element. The spring element can also be mechanically fixed to the contact element, so that the spring element is supported on the contact element and can thus be brought into contact with the contact element by means of the clamping leg.
For example, the contact element can have a fastening section on which the spring element is arranged. The spring element can be fixed to the fixing section of the contact element by the connecting end of the spring element, which is connected to the supporting leg and fixed to the fixing section, for example, in such a way that the spring element is held on the contact element. For example, a force-fit, form-fit and/or material-fit connection with the fastening section can be established via the connecting end, for example a (force-fit and form-fit) rivet connection, a (force-fit) screw connection or a (material-fit) welded or soldered connection. If the spring element is riveted to the fastening section of the contact element via the connecting end, the fastening section can, for example, pass through an opening in the connecting end, wherein the fastening section is plastically deformed to establish the rivet connection with the connecting end.
In one embodiment, the contact element has a column section for making electrical contact with the protective line. The clamping legs are formed here for clamping the protective wire in the clamping position in an electrically contacting manner with the column section, in particular by pressing the protective wire with the clamping legs, so that it comes into contact with the column section in an electrically contacting manner and thus establishes an electrical connection between the protective wire and the contact element.
The plug connector module can be inserted into the receiving opening of the receiving frame to connect the plug connector module with the receiving frame. The plug connector modules can be combined with other plug connector modules in the receiving frame, for example, to form an arrangement group of plug connector modules, which enables a modular, variable configuration of the plug surface to form a plug connector for connection with a mating plug connector.
The plug connector module is to be electrically contacted with the receiving frame and can for this purpose be designed, for example, to be electrically conductive on its housing. For example, the housing can be made entirely of an electrically conductive material, in particular a metal material, for example a zinc diecasting material, so that the housing of the plug connector module, when inserted into the receiving frame, comes into contact with the receiving frame and thereby makes electrical contact with the receiving frame. If the plug connector module is inserted into the receiving frame and the protective wire is connected to it, the receiving frame is thus at the potential of the protective wire.
In one embodiment, the housing has two facing away end faces which, when the plug connector module is inserted into the corresponding receiving frame, face the longitudinal sides of the receiving frame and via which the plug connector module is fixed to the receiving frame. For the arrangement on the receiving frame, the plug connector module is inserted with its housing between the longitudinal sides of the receiving frame in such a way that the end faces of the plug connector module housings facing away from each other are directed toward the longitudinal sides of the receiving frame and abut against the longitudinal sides of the receiving frame.
In one embodiment, the end faces are spaced apart from one another in the transverse direction. The transverse direction extends here, for example, transversely to an alignment direction, along which the plug connector modules can be aligned with one another in order to be accommodated together in the receiving frame. The longitudinal sides of the receiving frame are spaced apart from each other in the lateral direction and extend longitudinally parallel to each other in the array direction. The plug connector modules can be inserted into the receiving frame in an attachment direction, which is perpendicular to the transverse direction and the alignment direction.
In one embodiment, the plug connector module has a fastening element arranged on one of the end faces of the housing for a positive-locking connection with the receiving frame. For example, a respective fastening element can be provided on each end face, so that the plug connector module is connected to the longitudinal side on both sides when inserted into the receiving frame and is fastened to the longitudinal side in a form-fitting manner.
The fixing elements can be formed, for example, by locking projections which project from the housing in the transverse direction on the corresponding end faces. When inserting the plug connector module into the receiving frame, the fixing elements engage with corresponding locking elements on the sides of the receiving frame, for example in the form of locking springs arranged on the corresponding longitudinal sides, which lock the fixing elements and thus the plug connector module with the receiving frame in a form-fitting manner. This allows a simple assembly, for which the plug connector module is inserted into the receiving frame in the insertion direction and is automatically locked in place in the receiving frame.
In one embodiment, the housing has two housing parts which are attached to one another to form the housing. The housing parts are for example formed as identical parts. The housing part can, for example, embody two housing halves which are separated from one another along a separating plane enclosed by the transverse direction and the insertion direction and can be made of an electrically conductive material, for example a zinc diecasting material, for electrical contact with the receiving frame.
According to a further aspect, a plug connector assembly has a plug connector module according to the type described above for connecting protection lines and a receiving frame for receiving the plug connector module. The receiving frame has two opposite longitudinal sides, between which a receiving opening for receiving the plug connector module is formed. The longitudinal sides can be connected to one another, for example, by end faces of the receiving frames which are remote from one another in the alignment direction, so that the receiving frames form rectangular frames, in which rectangular receiving openings are formed for receiving combinations of plug connector modules.
In one embodiment, the plug connector modules can be combined with other plug connector modules on the receiving frame in the alignment direction. The plug connector modules, for example, make it possible to connect protection lines, while other plug connector modules can be connected, for example, to load lines, for example in the form of power lines or data lines. The housings of the other plug connector modules are preferably electrically non-conductive and therefore are not at the potential of the protective lines connected to the receiving frame via the plug connector modules designed as PE modules when they are inserted into the receiving frame.
Other plug connector modules may have connection possibilities for connecting wires on one side. On the other side remote therefrom, the plug connector module can form plug sections on which the electrical contact elements are arranged, which together form a plug surface that can be plugged with a corresponding mating plug connector.
In one embodiment, the receiving frame has at least one locking element for locking the plug connector module in the receiving frame. The receiving frame can in particular have an arrangement group of a plurality of locking springs, which makes it possible to mechanically fix a plurality of plug connector modules on the receiving frame. For example, the receiving frame can form a plurality of slots for receiving the plug connector modules, each slot being assigned two locking springs arranged on opposite longitudinal sides of the receiving frame, so that the plug connector modules can be locked in the respectively corresponding slot by means of a pair of locking springs, respectively.

Detailed Description
Fig. 1 to 3 show an exemplary embodiment of a plug connector assembly 1 having a receiving frame 2 and a plug connector module 3 which can be inserted into the receiving frame 2 in an insertion direction E corresponding to the attachment direction.
In the illustrated embodiment, the plug connector modules 3 are of modular design and can be combined with further plug connector modules along the alignment direction a to create an arrangement group of modules on the receiving frame 2, which modules together form a plug face of the plug connector for electrical connection with a corresponding mating plug connector 5.
The receiving frame 2 has a rectangular basic shape with longitudinal sides 20, 21 opposite each other, which are connected to each other by end faces 22, 23 extending in the transverse direction Q. The receiving frame 2 is made of an electrically conductive metal material and has contact means 220, 230 on its end faces 22, 23 for plug connection with corresponding contact means of the mating plug connector 5, in particular in order to place the receiving frame 2 at a protective potential (ground potential) common to the mating plug connector 5, for example, the receiving frame of the mating plug connector 5, when the receiving frame is plugged to the mating plug connector 5.
The plug connector modules 3 accommodated in the accommodating frame 2 enable the connection of electrical lines in the form of protection lines 4, as is schematically shown in fig. 2. The plug connector module 3 has a housing 30 which forms an insertion opening 301 for inserting and connecting the protection wire 4.
The plug connector module 3 thus forms a so-called PE module for connecting the protective line 4 and is brought to the protective potential of the protective line 4 when the protective line 4 is connected. For this purpose, the housing 30 is made of an electrically conductive material, for example a zinc diecasting material, and is in electrical contact with the receiving frame 2 when the plug connector module 3 is inserted into the receiving frame 2.
On the longitudinal sides 20, 21 of the receiving frame 2 facing each other, locking elements in the form of locking springs 24 are arranged for locking connection of the inserted plug connector module 3 with the receiving frame 2. In the plug-in position, the plug connector modules 3 are connected to the receiving frame 2 in a form-fitting manner and are locked on the receiving frame 2 by the locking springs 24, wherein further plug connector modules can be arranged alongside the plug connector modules 3 in the alignment direction a and are likewise connected to the receiving frame 2 at the respectively associated insertion slot by the corresponding locking springs 24.
Fig. 4 to 8 show an embodiment of a plug connector module 3, in which the housing 30 of the plug connector module 3 is formed by two housing parts 302, 303 made of an electrically conductive material, for example a zinc diecasting material, which are separated from one another along a separating plane enclosed by the insertion direction E and the transverse direction Q and are attached to one another to form the housing 30.
The housing 30 forms end faces 305,306 spaced apart from each other in the transverse direction Q and remote from each other. When the plug connector module 3 is inserted into the receiving frame 2, the housing 30 faces the longitudinal sides 20, 21 with these end faces 305,306, so that the plug connector module 3 is in contact with the longitudinal sides 20, 21 by means of the end faces 305,306 and is locked in the receiving frame 2 by means of the end faces 305, 306.
For locking, a fastening element 304 in the form of a locking projection is formed on each end face 305,306, which projects in the transverse direction Q from the respective end face 305,306 and is intended for locking connection with a respective corresponding locking element in the form of a locking spring 24 on the respective longitudinal side 20, 21. When the plug connector module 3 is inserted into the receiving frame 2 in the insertion direction E, each fixing element 304 is in locking engagement with the locking section 240 of the respective corresponding locking spring 24, so that a form-fitting connection of the plug connector module 3 with the longitudinal sides 20, 21 of the receiving frame 2 is thereby established on both end faces 305,306 of the housing 30.
The plug connector module 3 has a plug section 300 on the front side, on which electrical contact elements 31 are arranged, for example in the form of socket contacts. When the plug connector assembly 1 is used as intended, the plug connector modules 3 with the plug sections 300 face the corresponding mating plug connector 5, so that the mating plug connector 5 can be plug-connected with the plug connector modules 3 of the plug connector assembly 1.
In the exemplary embodiment of the plug connector module 3 shown in fig. 4 to 8, a connecting assembly 33, which is shown in the sectional view of the plug connector module 3 in fig. 9, is enclosed between the housing parts 302, 303 of the housing 30.
The connecting assembly 33 has a spring element 36 which forms a clamping leg 360 and a supporting leg 362 which is connected to the clamping leg 360 by a connecting section 361. The clamping legs 360 are elastically deflectable relative to the supporting legs 362, wherein the spring element 36 is supported on the housing 30 via the supporting legs 362 and is thereby fixed to the housing 30.
The connecting assembly 33 has an actuating element 34, which in the illustrated embodiment is formed as a slider that is slidably guided in the guide opening 307 of the housing 30 and faces outwards with a head 340, so that the actuating element 34 can be actuated by the user using a tool in order to transfer the clamping leg 360 of the spring element 36 into the release position. In the release position, the clamping space 35 in the housing 30 connected to the insertion opening 301 is released by the clamping legs 360, so that the protective wire 4 can be inserted into the insertion opening 301 and connected to the connecting assembly 33 substantially without force or the connected protective wire 4 can be removed from the connecting assembly 33.
In the exemplary embodiment shown, the actuating element 34 is operatively connected to the clamping leg 360 via the actuating section 341 in such a way that, by actuating the actuating element 34 in the actuating direction B, the actuating section 341 presses on the clamping leg 360 and moves it out of the region of the clamping space 35 in such a way that the protective wire 4 can be inserted into the insertion opening 301 of the housing 30 and introduced into the clamping space 35. If the actuating element 34 is released, the clamping leg 360 springs back in the direction of the clamping position due to its elastic tension relative to the supporting leg 362 and comes into contact with the protective wire 4, so that the protective wire 4 is electrically contacted and mechanically locked in the housing 30.
As can be seen from fig. 8 in conjunction with fig. 9, the spring element 36 is firmly connected to the fastening section 310 of the contact element 31 via the connecting end 363 adjoining the supporting leg 362, so that the spring element 36 is fastened to the contact element 31. Here, an opening is formed at the connection end 363, through which the protruding section of the securing section 310 is inserted, wherein a rivet is produced by plastic deformation of the securing section 310, via which rivet force-fitting and form-fitting the spring element 36 is secured to the contact element 31.
The contact element 31 forms a column section 311, into which column section 311 the clamping leg 360 of the spring element 36 engages in the clamping position and with which column section the protection wire 4 is clamped when connected to the plug connector module 3, so that the protection wire 4 is in electrical contact with the column section 311 and thus with the contact element 31.
For connecting the protective cable 4, the actuating element 34 can be actuated in an actuating direction B, so that the clamping leg 360 can be adjusted and the protective cable 4 can be inserted into the insertion opening 301 in the insertion direction E. However, it is also possible to connect the protective wire 4 to the connecting assembly 33 by direct insertion, i.e. without actuating the actuating element 34, wherein when connecting the protective wire 4, the clamping leg 360 is pushed aside by the conductor end of the protective wire 4 and the protective wire 4 is thus inserted into the region of the column section 311 in order to make electrical contact with the column section 311 by the action of the clamping leg 360.
In order to release the protective cable 4, the actuating element 34 can be actuated (again) in an actuating direction B in order to move the clamping legs 360 out of their clamping position and thus release the protective cable 4, so that the protective cable 4 can be removed from the insertion opening 301 counter to the insertion direction E.
In the exemplary embodiment of the connecting assembly 33 of the plug connector module 3 shown in fig. 10 and 11, which is otherwise functionally identical to the exemplary embodiment according to fig. 4 to 8, the spring element 36 has a clamping leg 360 which is connected to a supporting leg 362 via a connecting section 361 and extends through an opening 364 formed in the supporting leg 362, as shown in particular in fig. 10.
The spring element 36 is arranged on the fastening section 310 of the contact element 31 via a connection 363 formed on the support leg 362, in that the fastening section 310 engages in an opening 364 of the support leg 362 and is supported via the connection 363 on a column section 311 adjoining the fastening section 310.
When the protection wire 4 is connected, the protection wire 4 is engaged with the opening 364 of the support leg 362 with one conductor end and passes through the opening 364. For connecting the protective cable 4, the clamping leg 360 can be actuated by an actuating element 34 in the form of a slider that can be guided in the guide opening 307 of the housing 30, in order to release the opening 364 for inserting the protective cable 4. However, it is also possible to insert directly without manipulating the clamping leg 360, whereby the clamping leg 360 is pushed aside by the protection wire 4 when connected to the connecting assembly 33.
In the connected position, the protection wire 4 is engaged in the insertion opening 301 of the housing 30 and passes through the opening 364 of the support leg 362. In this case, the clamping legs 360 clamp the protective wire 4 in the opening 364 and press the protective wire 4 in electrical contact with the post section 311 on the contact element 31. By means of the clamping action of the clamping legs 360, the protective wire 4 is thereby electrically contacted with the contact element 31 and is furthermore mechanically locked on the connecting assembly 33.
If the protective wire 4 is to be detached again from the plug connector module 3, the actuating element 34 can be actuated in order to adjust the clamping legs 360 and release the protective wire 4 in this way.
As can be seen from fig. 11, in the embodiment shown in fig. 10 and 11, the handling direction B and the insertion direction E of the protection wires 4 into the insertion opening 301 of the housing 30 are at an angle to the attachment direction of the plug connector module 3 into the receiving frame 2.
Furthermore, the plug connector module 3 according to the embodiment of fig. 10 and 11 is essentially identical in function to the above-described embodiment, so that reference is also made to the preceding description.
The plug connector module 3 is designed as a so-called PE module for connecting protection lines. Accordingly, the housing 30 is electrically conductive, so that the protection wire 4 is also in electrical contact with the housing 30 when connected to the connection assembly 33, and with the receiving frame 2 when inserted into the receiving frame 2.
As can be seen from fig. 12A to 12C, a clamping device 32 is arranged on the plug connector module 3, which can be used for clamping locking and electrical contacting with the receiving frame 2, but can also be omitted if necessary. The clamping devices 32 each have a clamping block 320 and a tensioning element 321 in the form of a screw, by means of which a clamping connection can be created between the housing 30 and the edge wall sections 200, 210 of the longitudinal sides 20, 21 of the receiving frame 2.
The idea on which the invention is based is not limited to the embodiments described above but can also be implemented in other ways.
By using a connecting assembly of the type described, a reliable electrical contact is produced when connecting the protective wire, and also a secure mechanical locking and a simple operation for connecting and releasing the protective wire from the plug connector module are achieved.
The connecting assembly can also be inserted directly, i.e. the protective cable can be connected without actuating the actuating element.
