Definitions
- the present invention relates to the field of holding frames for modules and in particular to holding frames for a plug connector for accommodating similar and/or different modules.
- Retaining frames are used to hold several modules that are similar and/or different to one another.
- These modules can be insulating bodies, for example, which are provided as contact carriers for electronic and electrical and possibly also for optical and/or pneumatic contacts.
- EP 2 945 229 A1 discloses latch assemblies for connector systems, a connector system including a cartridge having at least one cavity configured to retain connector modules therein.
- the cartridge has at least one opening and the cartridge is configured to receive the connector modules through the corresponding at least one opening.
- the cartridge houses at least one slide latch which is longitudinally movable.
- the at least one slide latch has at least one profiled groove configured to latch-receive a cam of the corresponding connector module to fix the connector modules to the cartridge and further has a biasing member coupled thereto.
- the biasing member biases the at least one slide lock in a biasing direction, the biasing member urging the at least one slide lock to return to a locked position after the cam is received in the profile groove.
- At least one disengagement slide is operable on the respective slide latch which is adapted to be moved to force the slide latch to move from the latched position to a release position to disengage the cam from the respective profile groove to disengage each of the eject the connector module received in the cartridge from the cartridge.
- the connector system has a release mechanism configured to move the at least one release slider.
- JP H08 273753 A discloses a plug-in and unplug connector.
- connector-containing body are provided with frames, with frame blocks holding the frames, with sections containing the connectors, and with driving means that move the connectors in the insertion-extraction direction.
- Projection movement windows are provided in the frames, from which projections of the connectors protrude.
- the driving means are each equipped with a driving slide guided by guide portions of the frames, which moves the connectors in the insertion-extraction direction by moving the projections.
- EP 0 860 906 B1 discloses a holding frame for holding connector modules and for installation in connector housings or for screwing to wall surfaces, with the connector modules being inserted into the holding frame and holding means on the connector modules interacting with recesses provided on opposite wall parts (side parts) of the holding frame, with the recesses acting as openings closed on all sides are formed in the side parts of the holding frame, the holding frame consisting of two halves which are hinged to one another, the separation of the holding frame being provided transversely to the side parts of the frame, and joints being arranged in the fastening ends of the holding frame in such a way that when Screwing the holding frame onto a mounting surface, the frame parts align in such a way that the side parts of the holding frame are aligned at right angles to the mounting surface and the connector modules have a positive connection with the holding frame via the mounting means.
- such holding frames are usually manufactured in a die-casting process, in particular in a zinc die-casting process.
- the pamphlet EP 2 581 991 A1 discloses a holding frame for connector modules, which has two frame halves, which can be latched together by linear displacement of one frame half relative to the other frame half in a sliding direction, with latching means corresponding to one another being provided on the frame halves, which upon linear displacement cause the two frame halves to latch into one another in two cause different locking positions in which the frame halves are spaced at different distances from each other.
- such holding frames require complex operation during assembly.
- such holding frames must be unscrewed and/or unlatched from the connector as soon as even a single module is to be replaced.
- the other modules whose removal was not desired at all, may also fall out of the holding frame and then have to be reinserted before the frame halves are screwed together and/or locked in place.
- all modules must be in the intended position at the same time in order to be finally fixed in the holding frame when the frame halves are assembled, which makes assembly more difficult.
- the pamphlet EP 1 801 927 B1 discloses a support frame made from a one-piece plastic injection molding.
- the holding frame is designed as a peripheral collar and has a plurality of wall segments separated by slots on its plug-in side. Two opposite wall segments each form an insertion area for a connector module, with the wall segments having window-like openings which serve to accommodate projections formed on the narrow sides of the modules.
- a guide groove is provided in each of the wall segments. The guide groove is formed above the openings by means of a window web which is offset outwards and has an insertion bevel on the inside.
- the plug-in modules have latching arms which are formed on the narrow sides and act in the direction of the cable connections and latch below the lateral collar wall, so that two independent latching means fix the connector modules in the holding frame.
- the disadvantage of this prior art is that it is a holding frame made of plastic, which is generically not suitable for protective earthing, for example according to the connector standard EN61984, so that such a holding frame is not suitable for installation in metallic connector housings can be used.
- metallic connector housings requires such a protective earthing and is necessary in many cases due to their mechanical robustness, their temperature resistance and their electrically shielding properties and is therefore desired by the customer.
- the production of the above-mentioned plastic holding frames in the injection molding process is at least difficult and can only be realized with great effort.
- the heat resistance of such a plastic holding frame is not always sufficient for special applications, for example in the vicinity of a blast furnace.
- such a holding frame By separating the material properties of the base body from those of the deformation section, such a holding frame allows greater flexibility through suitable material combinations.
- the deformation section is formed by cheek parts, which are attached to the outside of a base frame, with the cheek parts each having a bending line in their lower end area, on which the cheek parts are folded through 180°, so that a closing edge of the respective cheek part is inside the Base frame is located.
- the base frame has fastening pins on the outside, which engage in corresponding fastening recesses when a cheek part is attached.
- the EP 1 801 927 B1 and DE 10 2013 113 976 A1 each have limitations for the locking windows that the locking lugs of the modules, which move outwards, in the width direction, when a module is inserted, so that the minimum required installation space is given by the width of the module plus the respective strengths of the locking window limitations, with additional space being required as a result of pivoting during deformation .
- One objective underlying the present invention is to provide a holding frame that allows a module to be inserted and possibly also removed with the smallest possible space requirement, even in an installed state.
- a holding frame for a connector for accommodating modules of the same type and/or different is proposed, as defined in claim 1 .
- a method for equipping a holding frame for a connector for accommodating similar and/or different modules with a module is proposed, as defined in claim 6 .
- the holding frame divided into parts as a whole gives way to the modules or their latching lugs during insertion, in order to clear a path to a position of the module in which the module can be fixed by the returning holding frame.
- the holding frame off EP 1 801 927 B1 and DE 10 2013 113 976 A1 provide a similar evasion, but here only a part of the holding frame, which can otherwise essentially remain in the installed state. What these approaches have in common, however, is that the "making room” takes place by moving outwards, which can result in a correspondingly greater need for space. This space requirement can be reduced by reducing the thickness of the yielding element, although this is associated with lower strength and/or higher demands on the material properties.
- the way for the latching lug of a module can also be cleared by parts of the holding frame deflecting sideways, i.e. along a plane resulting from the side wall of the holding frame, with such deflection not increasing Space required to the outside brings with it.
- the space that surrounds the detent laterally (in the sense of the side wall plane) is thus used here to a certain extent.
- the rigid base frame which serves as a stable framework, forms a basis for the holding frame according to the invention.
- clip springs are attached as fixing elements that are firmly connected to the base frame. If a module is pushed in, these springs (opposite each other) swing sideways, let the module (or its locking lugs) pass and snap together again as soon as the module has reached its end position in the holding frame. The module is now held between the legs of the clip spring.
- sheet metal elements pivot outwards, away from the module, so that additional space is required compared to the module width.
- the clip spring does not pivot outwards (away from the module), but moves laterally, ie perpendicularly to the longitudinal direction of the module. In this way, no additional space is required in the longitudinal direction of the module.
- the fixing element has a round or rectangular wire and/or an elastic plastic or spring steel sheet.
- the formation of the fixing element and in particular of the fixing arm from a round or rectangular wire allows simple and inexpensive production, with the wire being brought into the shape required to fulfill its shape in a suitable manner.
- the wire itself preferably retains an elasticity that then ensures elastic deformation when the module is inserted. Production from an elastic plastic is also possible at low cost.
- the invention can also be implemented with a fixing element stamped from sheet metal.
- the base frame has a stop for the locking lug in the direction of insertion.
- the spatial design of the base frame defines the positioning of the module within the base frame (and thus within the holding frame).
- the base frame itself can thus be used to absorb loads from the module that are caused by a train on the module (e.g. when loosening a plug connection) without such loads acting on the fixing element.
- the base frame has a guide for guiding the latching lug when the module is inserted into the holding frame.
- the fixing element is form-fitting, force-fitting and/or material-to-material on the inside and/or attached to the outside of the base frame and/or within a side wall of the base frame, in particular glued, welded, soldered, riveted, latched and/or screwed.
- the invention is not limited to a specific relative positioning of the fixing element with respect to the side wall, i.e. it can be inside (i.e. in the interior of the holding frame), outside or also in a direction extending approximately inside the side wall in the direction of insertion Cavity are arranged, and combinations can be provided.
- a suitable type of attachment can be selected, with a form fit being particularly preferred in the present case, since this can be achieved with little effort in the manufacture or assembly of the holding frame if the design is skilful.
- the fixing element is fitted in a depression on the inside of the side wall and is fixed in the insertion direction by limitations of the depression, the fixing element also having a clamping piece which extends through an opening in the side wall and/or around an edge the side wall extends to the outside of the side wall and with which the fixing element is secured against falling out of the recess.
- the fixing element Due to the fact that the fixing element is provided in a depression on the inside of the side wall, the fixing element is well secured against external influences, particularly when the module is inserted.
- the depression also allows the base frame with its inner side face to again guide the module in the transverse direction when it is inserted, so that the fixing element is in turn less exposed to the risk of damage.
- the clamping piece also provides a form fit against movement transverse to the side wall, while the delimitations of the recess secure the fixing element as a whole against movement within a plane defined by the side wall by means of a form fit.
- the fixing element is clamped with a clamping section on the inside of the side wall.
- the fixing element can also be connected to a projection protruding from a part of the inside of the side wall as a clamping section with a frictional connection achieved by clamping.
- the fixing element can extend around the projection and, in another, supplementary or alternative variant, can be arranged inside the projection (from another point of view inside a recess).
- part of the fixing element extends through an opening in the side wall and is clamped in this opening.
- the fixing element is arranged in parts on the outside of the side wall and in parts on the inside of the side wall and interlocks with at least a part of the base frame.
- This aspect can also be an alternative to the two previous ones or combined with one or both.
- the fixing arm has a fixing hook with a flank and a shoulder, the flank being intended to come into contact with the latching lug of the module when the module is inserted, so that when the module slides along Detent on the edge of the fixing arm is deformed in the direction of the insertion state, the shoulder being configured for at least partial engagement with the detent of an inserted module in the holding state.
- the shaping of the fixing hook results on the one hand from the spatial design in a desired cooperation between the fixing arm and the locking lug of the module when the module is inserted into the holding frame.
- the step that preferably occurs with the flank ensures the form fit with the locking lug in a simple manner.
- the fixing arm has a manipulation element that protrudes beyond an upper edge of the base frame and/or an inserted module and allows manual deformation of the fixing arm.
- the fixing arm extends so far that it is accessible to a user even with the module inserted and fixed, this can allow a module to be removed from the holding frame without any additional tools or the like, in which the user slides the fixing arm over the Brings manipulation element in the insertion state, in which the module can be removed.
- the fixing element is designed for fixing the module in the holding state by means of a positive fit of the fixing arm with the latching lug of the module.
- the invention is not limited to fixing or holding the module by means of a positive fit between the fixing element (mainly the fixing arm) and the locking lug, i.e. a friction fit or other force fit can also be provided, for example, the use of a positive fit is possible due to the associated reliability and the possibility of being able to use a relatively simple construction for this purpose.
- the fixing element is designed for elastic deformation between the insertion state and the holding state.
- An elastic deformation means that with the omission of the force acting on the fixing element, which causes a deformation from the holding state to the insertion state (e.g. the force caused by the displacement of the fixing arm(s) through the locking lug(s) of the module during insertion ), the fixing element itself ensures the return to the holding state.
- the deformation is a plastic deformation, as long as sufficient reversibility of this deformation is ensured to allow a desired number of insertion and removal cycles of the module.
- the fixing element has two fixing arms, between which there is a latching area for receiving a latching lug of a module.
- the invention can basically already be implemented by the provision of a fixing arm in the context of a fixing element, in particular when a secure form fit of the locking lug and fixing arm can be achieved through an interaction of the geometric design of the base frame (e.g. with a stop and a guide).
- a secure form fit of the locking lug and fixing arm can be achieved through an interaction of the geometric design of the base frame (e.g. with a stop and a guide).
- two fixing arms are provided, which enclose the latching lug of an inserted module between one another in the holding state, the same form-fit dimension can be achieved with a reduced extent of deformation per fixing arm.
- the invention is also not limited to a fixing element with two fixing arms, since a fixing element can also have several fixing arms within the scope of the invention, one or two of which are provided for holding a latching lug of a module in the holding state.
- two fixing elements that are otherwise separate from one another can also interact, with a fixing arm of one fixing element together with a fixing arm of the other fixing element defining and delimiting the locking area for receiving the locking lug.
- two fixing elements are provided opposite one another on the two side walls for fixing a module with opposite locking lugs, multiple fixing elements preferably being provided next to one another in the longitudinal direction of the side walls.
- the holding frame is consistently equipped with fixing elements on the respective opposite sides on the side walls for all module locations that are respectively provided for receiving an inserted module.
- the base frame on the one hand and the fixing element on the other hand are at least partially formed from different materials.
- the base frame and fixing element(s) fulfill different functions.
- the base frame should preferably essentially determine the general rigidity of the holding frame, while the fixing element or elements should have the simplest possible and preferably elastic deformability. These different functions can best be fulfilled largely independently of one another by choosing your own suitable material for the base frame and fixing element(s).
- the base frame is at least partially made by die casting from a metal, preferably zinc or aluminum, or a metal alloy, preferably a zinc or aluminum alloy.
- FIG. 1 shows a view of a holding frame according to a first embodiment of the invention with modules, wherein 2 an enlarged detail of the view from 1 shows and 3 Another enlarged section of the view from 1 shows.
- the holding frame 1 is shown here with an already inserted module 9 and a further module 9 which is offset relative to the inserted module 9 against the direction of insertion.
- the holding frame 1 comprises a base frame 111 which has two end faces 112 (only one shown) and two side walls 113 (only one shown).
- this has three receptacles for latching lugs 91 of modules 9 in each side wall 113, which are delimited by a stop 114 and two guides 115 lying opposite one another.
- the guides 115 are provided on opposite sides of the base frame 111 at different distances, so that a wider locking lug 91 of a module can be accommodated on one side than on the opposite side. This allows protection against polarity reversal or incorrect orientation of the module 9 when it is plugged in.
- the side walls 113 each have a depression 116 on some of their insides. This depression 116 can also be described as the side walls 113 having a smaller wall thickness in certain areas 116 when the outside is planar, as in this example, so that there is a certain free space between the side wall 113 and an inserted module 9 along the side wall 113 .
- This free space is delimited in the plane of the side wall 113 by limitations 117, at which the wall thickness in the present example increases in a shoulder or step to the other wall thickness of the side wall 113.
- each side wall 113 has an opening 118 which is continuous from the outside to the inside and which also has a section with a reduced wall thickness on the inside of the side wall 113 .
- a fixing element 120 is attached to the base frame 111 in the area of each receptacle.
- the fixing element 120 comprises two fixing arms 121 which are connected to one another - in this exemplary embodiment - in such a way that the fixing element extends between the boundaries 117 in such a way that a form fit in the plane defined by the side wall 113 between the boundaries 117 and the fixing element 120 this is fixed in this plane.
- the fixing arms 121 can move within the depression 116 with a corresponding deformation of the fixing element 120 .
- this has a clamping piece 122 that extends through the opening 118 in the side wall 113 and rests against the wall on the outside of the side wall in the section with the reduced wall thickness, so that by the relative relationship of the clamping piece 122 and the rest of the fixing element 120 to one another, the fixing element is held on the side wall.
- a fixing hook 123 which is formed by bending the wire in an approximately triangular shape and has a flank 124 and a shoulder 125 .
- a latching area 126 for receiving the respective latching lug 91 of a module 9.
- the latching lugs 91 each come between the guides 115 of the base frame 111 and then reach the fixing hooks 123 of the fixing arms 121 of the respective fixing element 120.
- a certain amount of force when continuing the insertion causes the latching lugs 91 , which each slide along the flanks 124, the fixing arms 121 are deformed, the fixing hooks 123 being moved laterally in the sense of transversely to the module 9.
- the force that maintains the deformation of the fixing arms 121 no longer acts on the fixing hooks 123 or fixing arms 121, and the fixing arms spring back into a position such as that in 2 can be seen.
- plastic deformation is also possible, although a corresponding action by a user is then necessary in order to bring about the return of the fixing arms.
- the shoulders 125 and the stop 114 enclose the locking lug in such a way that a forward and backward movement of the module 9 in the insertion direction is not possible or only possible to a very limited extent. Due to the contact of the guides 115 with the locking lug 91, this is also fixed or almost fixed in the transverse direction of the module 9 (the longitudinal direction of the holding frame 1). With appropriate dimensioning of the inner sides of the side walls 113 from one another, a movement of the module 9 in its longitudinal direction can also be prevented or limited, so that the module 9 is fixed in three spatial directions.
- the fixation of the module 9 in the holding frame can be released if there is a possibility of external action on the fixation arms 121 in order to remove the fixation hooks 123 in front of the locking lug 91 of the module (by bending up the fixation arms 121 accordingly).
- Shoulder 125 preferably has a slight incline in the direction of fixing arm 121, so that when a force acts against the direction of insertion on an inserted module 9 with a certain deformation of fixing element 120, shoulder 125 comes to rest flat on the surface of the latching lug in order to better to suppress further bending.
- the step it is also possible for the step to have a slope in the opposite direction, so that bending open the fixing arms is possible with a correspondingly large expenditure of force without damaging the holding frame.
- FIG. 4 shows a view of a holding frame according to a second embodiment of the invention with modules.
- figure 5 shows a partial side view of the holding frame 4 and 6 shows an enlarged view of the holding frame 4 without modules.
- 7 shows a partial sectional view of the holding frame 4 without modules and 8 shows two views of a fixing element of the holding frame 4 .
- the holding frame 2 of the second exemplary embodiment comprises, comparable to that of the first exemplary embodiment, a base frame 211 with two end faces 212 and two side walls 213. Unlike the first exemplary embodiment, the holding frame 2 is designed to accommodate six modules 9 and to fix them using their locking lugs 91 provided.
- the base frame 211 includes respective guides 215 and stops 214 for receiving the locking lugs 91.
