Description

Holding frame for a connector and method of assembly

description

The present invention relates to the field of support frames for modules and in particular of support frames for a connector for receiving similar and / or different modules. Holding frames are used to accommodate several similar and / or different modules. These modules can be, for example, insulating bodies, which are provided as contact carriers for electronic and electrical and possibly also for optical and / or pneumatic contacts.

Document EP 0 860 906 B1 discloses a holding frame for holding plug-in connector modules and for mounting in plug connector housing or for screwing to wall surfaces, the plug connector modules being inserted into the holding frame and holding means on the plug connector modules having opposite wall parts (side parts). the recesses are formed as mutually closed openings in the side parts of the holding frame, wherein the holding frame consists of two articulated halves, wherein the separation of the holding frame is provided transversely to the side parts of the frame, and wherein joints in the attachment ends of the holding frame are arranged such that when screwing the holding frame on a mounting surface, the frame parts align such that the side parts of the holding frame are aligned at right angles to the mounting surface and the plug have connector modules via the support means a positive connection with the support frame. In practice, such holding frames are usually produced in a die-casting process, in particular in a zinc die-casting process.

Document EP 2 581 991 A1 discloses a holding frame for plug connector modules which has two frame halves which can be locked together by linear displacement of one frame half relative to the other frame half in a sliding direction, whereby in each case corresponding locking means are provided on the frame halves. cause the linear displacement locking the two frame halves together in two different locking positions in which the frame halves are spaced at different distances from each other. However, it has been found in practice that such mounting frames require a complex operation during assembly. For example, such support frame must be unscrewed from the connector and / or unlocked as soon as a single module to be replaced. In this case, possibly fall the other modules whose removal was not desirable, out of the support frame and must then be reinserted before screwing together and / or before locking the frame halves. Finally, all modules must already be in the position provided for them before assembly of the frame halves, in order to be finally fixed in the mounting frame when joining the frame halves, which complicates the assembly.

The document EP 1 801 927 B1 discloses a holding frame, which consists of a one-piece plastic injection part. The holding frame is formed as a circumferential collar and has on its side plug a plurality of separated by slots wall segments. Two opposite wall segments each form an insertion region for a plug module, the wall segments having window-like openings which serve to receive projections formed on the narrow sides of the modules. Furthermore, in each case a guide groove is provided in the wall segments. The guide groove is formed above the openings by means of an outwardly offset window web, which has an insertion bevel on the inside. In addition, the plug-in modules have locking arms, which are formed on the narrow sides in the direction of the cable connections, molded, and latch below the lateral collar wall, so that two independent locking means fix the connector modules in the holding frame.

A disadvantage of this prior art is, on the one hand, that it is a holding frame made of plastic, which is not suitable for a protective earthing according to the EN61984 connector standard, so that such a holding frame is thus not suitable for installation in Metallic connector housing can be used. However, the use of metallic connector housings requires such protective grounding and in many cases is necessary because of its mechanical robustness, its temperature resistance and because of its electrical shielding properties, and is therefore desired by the customer. Furthermore, it has been shown that the production of the aforementioned plastic support frame by injection molding is at least difficult and can be realized only with great effort. Finally, the heat resistance of such a plastic support frame for special applications, for example in the vicinity of a blast furnace, is not always sufficient. In order to specify a design for a support frame, on the one hand has a good heat resistance and high mechanical robustness and especially when installed in a metallic connector housing a corresponding protective grounding, in particular a PE ("Protection Earth"), and on the other hand a comfortable operability, especially when replacing individual modules guaranteed, is proposed in the document DE 10 2013 1 13 976 A1, a base portion (preferably made by die casting, such as zinc or aluminum or a corresponding alloy) for fixing a recorded module in a plane and providing a deforming portion (preferably a stamped and bent resilient sheet) capable of adopting an insertion state and a holding state, the insertion state permitting insertion of at least one module in a direction transverse to the plane in the support frame, and e is fixed in recorded module in the holding state. In this case, the base portion and the deformation portion are formed at least partially of different materials in each case.

By virtue of the detachment of the material properties of the basic body from those of the deformation section, such a holding frame allows greater flexibility by means of suitable material combinations.

In the support frame described in DE 10 2013 1 13 976 A1, the deformation section is formed in each case by cheek parts, are mounted on the outside of a base frame, the cheek parts each having a bending line in its lower end region, at which the cheek parts folded by 180 ° are so that a final edge of the respective cheek part is located within the base frame. For attachment of the cheek part is in this case provided that the base frame has externally mounting pins which engage in an attached cheek part in corresponding mounting recesses.

The holding frames known from EP 0 860 906 B1 and EP 2 581 991 A1 do not permit a module to be inserted or removed in the installed state of the holding frame, since in each case frame halves must be moved as a whole. While this restriction does not apply to the holding frame known from EP 1 801 927 B1 and DE 10 2013 1 13 976 A1, there is a problem with the fact that, when fitted or removed in the installed state, a space must be provided which has a width which greater than the width of the modules, that is larger than the measure of the outer edges of the opposite locking lugs each other. EP 1 801 927 B1 and DE 10 2013 1 13 976 A1 each have boundaries for the latching windows which noses of the modules, on, in the insertion of a module to the outside, in the width direction, dodge, so that a minimum necessary space is given by the width of the module plus the respective strengths of the Rastfensterbegrenzungen, where necessary by pivoting during deformation optionally additional space consists.

One of the present invention underlying object is to provide a support frame, which allows insertion and possibly also removal of a module with the smallest possible space required in an installed state.

It is therefore desired to present a solution that allows a holding frame in a built-in state with little or no additional space around the support frame around to equip a module.

According to the invention, a holding frame for a connector for receiving similar and / or different modules is proposed according to a first aspect, as defined in claim 1, namely with a base frame defining a plane transverse to an insertion direction of a module in the holding frame and each other opposite end faces and side walls, and a fixing member which is attached to a side wall of the base frame and which is configured for a deformation between an insertion state, which allows insertion of the module in the insertion direction in the holding frame, and a holding state in which an inserted module is fixed by a latching lug of the module and the fixing element at least along the insertion direction, wherein the fixing element is configured such that the deformation comprises a movement of at least one fixing arm of the fixing in the longitudinal direction of the side wall.

According to the invention, according to a second aspect, a method for equipping a holding frame for a connector for receiving similar and / or different modules with a module is proposed, as defined in claim 1 0, namely with an insertion of the module into a base frame, the one plane defined transversely to an insertion direction of the module in the holding frame and each having opposite end faces and side walls, wherein the insertion comprises passing a locking lug of the module at a portion of a fixing arm of a fixing element, which is attached to a side wall of the base frame and that for a deformation between an insertion state, which allows insertion of the module in the insertion direction in the holding frame, and a holding state in which an inserted module by the latching lug of the module and the fixing element is fixed at least along the insertion direction, wherein the fixing element is in passing at least at an instant in the insertion state, wherein the method comprises a deformation of the fixing of the insertion state to the holding state and wherein the deformation movement of at least the fixing of the fixing in the longitudinal direction of the side wall includes.

Part of the background of the present invention can be found in the following considerations.

In the case of the EP 0 860 906 B1 and EP 2 581 991 A1 known retaining frame deviates into parts of the frame as a whole the modules or their locking lugs during insertion, so as to clear a path to a position of the module in which the module through the returning holding frame can be fixed. The support frames from EP 1 801 927 B1 and DE 10 2013 1 13 976 A1 also provide for a similar avoidance, but in this case only a part of the support frame, which otherwise can remain substantially in the installed state. Common to all these approaches, however, is that the "placements" are made by evading outwards, which can be associated with a correspondingly greater space requirement.This space requirement can be reduced by reducing the strength of the evasive element, but with a lower It has been recognized within the scope of the present invention that the path for the latching lug of a module can also be cleared by virtue of parts of the holding frame being deflected laterally, that is to say along a plane which extends from one another The side wall of the holding frame yields, whereby such an evasion does not entail an increased need for space to the outside, so that in a certain sense the space is used here which surrounds the detent laterally (in the sense of the side wall plane).

A basis for the holding frame according to the invention forms the rigid base frame, which serves as a stable framework. In or on this base frame clamp springs are attached as fixing elements, for example, which are firmly connected to the base frame. When a module is pushed in, these springs (opposite one another) pivot laterally, allow the module (or its latching lugs) to pass and snap together again as soon as the module has reached its final position in the holding frame. Now we held the module between the legs of the clamp spring. In known from the prior art holding frame pivot plate elements to the outside, away from the module, so that in this case there is additional space compared to the module width. As part of of this invention, as an example of a fixing member, does not swing the clamp spring outward (away from the module), but moves laterally, ie, at right angles to the longitudinal direction of the module. In this way, no additional space is required in the longitudinal direction of the module. In an advantageous embodiment of an aspect of the invention, the fixing element on a round or rectangular wire and / or an elastic plastic or spring steel.

The formation of the fixing element and in particular the fixing of a round or rectangular wire allows a simple and inexpensive production, wherein the wire is brought in a suitable manner to the shape required to fulfill its shape. The wire itself preferably retains an elasticity with which a then elastic deformation during insertion of the module is ensured. A production of an elastic plastic is inexpensive possible. With a suitable design with regard to the shape, the invention can also be realized with a fixing element stamped from a sheet metal.

In another advantageous embodiment of an aspect of the invention, the base frame has a stop for the locking lug in the insertion direction.

With a stop, the spatial design of the base frame defines the positioning of the module within the base frame (and thus within the support frame). The base frame itself can thus be used to pick up loads from the module, such as by pulling on the module (e.g., when releasing a connector), without such loads acting on the fixing member.

In another advantageous embodiment of an aspect of the invention, the base frame has a guide for guiding the latching nose during insertion of the module into the holding frame.

With such a guide, the path of the module is predetermined during insertion, so that a fault during insertion can be better prevented. The fact that the more stable base frame makes the guide of the module, it can also be prevented that occurs in a faulty operation damage to the fixing elements. If guides with, for example, different widths are provided on the opposite sides of the base frame, this can be achieved in interaction be used with a corresponding interpretation of the locking lugs of the module to a reverse polarity protection, in which a module is to be inserted only in a predetermined orientation in the holding frame.

In another advantageous embodiment of one aspect of the invention, the fixation element is positively, positively and / or materially attached to the inside and / or 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 bolted.

As long as a sufficient attachment is ensured as such, the invention is not limited to a specific relative positioning of the fixing element with respect to the side wall, ie within (ie in the interior of the support frame), outside or even in an approximately in the insertion direction in the interior of the side wall extending Cavity are arranged, and combinations may be provided. Depending on the configuration of the fixing element (for example with regard to choice of material), a suitable type of fastening can be selected, wherein in the present case a positive connection is preferred in particular, since this can be achieved with a skilful construction with little effort in the production or assembly of the support frame.

In another advantageous embodiment of an aspect of the invention, the Fixie-element is mounted in a recess on the inside of the side wall and is fixed by boundaries of the recess in the insertion direction, wherein the fixing further comprises a clamping piece extending through an opening in the side wall and / or extends around an edge of the side wall to the outside of the side wall and with which the fixing element is secured against falling out of the recess. Characterized in that the fixing element is provided in a recess on the inside of the side wall, the fixing element is in particular in a state with inserted module against external influences well secured. The recess also allows the base frame with its inner side surface again takes over a guide of the module in the transverse direction during insertion, so that in turn the fixing is less exposed to risk of damage. With the clamping piece is also given a positive engagement against a movement transverse to the side wall, while the boundaries of the recess the fixing element as a whole by molding secure against movement within a plane defined by the side wall.

In another advantageous embodiment of an aspect of the invention, the fixing element is clamped with a clamping portion on the inside of the side wall. As an alternative or in addition to the previous embodiment, the fixing element can also be connected to a protrusion, which is achieved by clamping, with a projection projecting from a part of the inside of the side wall as a clamping section. The fixing element may in this case extend around the projection in a variant as well as be arranged in another, supplementary or alternative variant within the projection (from a different point of view within a recess)

However, it is also possible that a part of the fixing element extends through an opening in the side wall and is clamped in this opening.

In another advantageous embodiment of an aspect of the invention, 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 interlocked with at least a part of the base frame.

This embodiment may also be alternative to the two previous ones or be combined with one or both.

In another advantageous embodiment of an aspect of the invention, the fixing arm has a fixing hook with a flank and a shoulder, wherein the flank is provided to come in an insertion of the module with the locking lug of the module in contact, so that when sliding along the Detent nose is deformed on the flank of the fixing in the direction of Einführzustands, wherein the paragraph for at least partial engagement with the latching lug of an inserted module in the holding state is configured.

Due to the shape of the Fixierhakens results on the one hand already by the spatial design a desired cooperation of fixing and locking lug of the module during insertion of the module in the holding frame. On the other hand, secures with the edge preferably resulting paragraph the positive connection with the locking lug in a simple manner. In another advantageous embodiment of an aspect of the invention, the fixing arm has a manipulation element which projects beyond an upper edge of the base frame and / or an inserted module and allows manual deformation of the fixing arm. If the fixing arm extends so far that it is accessible to a user even with inserted and fixed module, this may allow that a module can be removed without further tools or the like again from the holding frame, in which the user the fixing arm on the Manipulation element brings in the insertion state, in which the module can be removed. In another advantageous embodiment of an aspect of the invention, the fixing element for fixing the module in the holding state is configured by a positive connection of the fixing arm with the latching lug of the module.

Although the invention is not limited to a fixing or holding the module by a positive connection of fixing (especially the fixing) and locking lug, so for example, a frictional connection or other frictional connection can be provided, the use of a positive connection due to the associated reliability and the possibility prefers to be able to use a relatively simple construction for this purpose.

In another advantageous embodiment of an aspect of the invention, the fixing element is designed for elastic deformation between the insertion state and the holding state.

Elastic deformation is associated with the omission of the force acting on the fixing element, which causes a deformation from the holding state into the insertion state (eg, the displacement of the fixing arm (s) by the locking nose (s) of the module during insertion caused force), the fixing element itself ensures the return to the holding state. However, it can also be provided that the deformation is a plastic deformation as long as sufficient reversibility of this deformation is ensured in order to allow a desired number of insertion and removal cycles of the module. In another advantageous embodiment of an aspect of the invention, the fixing element has two fixing arms, between which there is a latching area for receiving a latching lug of a module. Basically, the invention can be realized already by providing a fixing arm in the context of a fixing element, in particular when a secure positive engagement of locking lug and fixing arm can be achieved by an interaction of geometric design of the base frame (such as a stop and a guide). However, if two fixing arms are provided, which in the holding state enclose the locking lug of an inserted module between each other, the same positive locking dimension can be achieved with per deformation arm reduced deformation amount.

The invention is also not limited to fixing with two fixing arms, as a fixing in the invention may also have a plurality of fixing arms, of which in each case one or two are provided for holding a latching lug of a module in the holding state.

As an alternative to the fact that two fixing arms of a fixing element are provided together for holding a latching lug of a module, two fixing elements which are otherwise separate from each other can cooperate, wherein a fixing arm of one fixing element together with a fixing arm of the other fixing element define the latching area for receiving the latching lug and circumscribe.

In another advantageous embodiment of an aspect of the invention, two fixing elements are provided opposite each other on the two side walls for fixing a module with opposite latching lugs, wherein preferably a plurality of fixing elements are provided side by side in the longitudinal direction of the side walls. In particular, it is preferred that the holding frame is consistently provided with fixing elements on all of the mutually opposite sides on the side walls for all module places which are respectively provided for receiving an inserted module. In another advantageous embodiment of an aspect of the invention, the base frame on the one hand and the fixing element on the other hand are at least partially formed of different materials.

Base frame and fixing element (s) fulfill different functions within the scope of the invention. The base frame should preferably substantially determine the general rigidity of the holding frame, while the fixing element (s) should have as simple and preferably elastic deformability as possible. These different functions can best be achieved by using your own and suitable material. Selection for base frame and fixing (s) largely independent fulfill.

In another advantageous embodiment of an aspect of the invention, the base frame is at least partially made by die casting, in particular of a metal, preferably of zinc or aluminum, or a metal alloy, preferably a zinc or aluminum alloy.

Known approaches and techniques for the production of a conventional base frame can be used with suitable geometrical adaptation of the forms for base frame, which are used in the present invention.

Features of advantageous embodiments of the invention are defined in particular in the dependent claims, wherein further advantageous features, embodiments and embodiments for the skilled person also from the above explanation and the following discussion can be found.

In the accompanying drawings, as well as the explanations to these drawings, corresponding or related elements, as appropriate, are identified with corresponding or corresponding reference numerals, even though they may be found in different embodiments.

Fig. 1 shows a view of a holding frame according to a first embodiment of the invention with modules, wherein Fig. 2 is an enlarged detail of the view of Fig. 1 shows and Fig. 3 shows another enlarged section of the view of Fig. 1.

The holding frame 1 is here shown with an already introduced module 9 and another module 9, which is offset from the inserted module 9 against the insertion direction.

The support frame 1 comprises a base frame 1 1 1, the two end faces 1 12 (only one shown) and two side walls 1 13 (only one shown).

Starting from the upper edge of the base frame 1 1 1 has this in each side wall 1 13 three receptacles for locking lugs 91 of modules 9, which are limited by a stop 1 14 and two opposing guides 1 15.

The number of shots is merely illustrative and the invention is not limited in this respect, so that other number of modules in holding frame according to the invention can be provided.

The guides 1 15 are provided on opposite sides of the base frame 1 1 1 with different distances, so that on one side a wider locking lug 91 of a module can be accommodated as on the opposite side. This allows a backup against reverse polarity or a wrong orientation of the module 9 during insertion.

On their insides, the side walls 1 13 each partially a recess 1 1 6 on. This depression 16 can also be described by the fact that, as in this example, the side walls 1 13 have a smaller wall thickness in certain areas 16, so that between the side wall 13 and an inserted module 9 along the side wall 1 13 there is a certain amount of freedom.

This clearance is limited in the plane of the side wall 1 13 by boundaries 1 17, at which the wall thickness increases in the present example in a paragraph or a step on the other wall thickness of the side wall 1 13.

Below (ie further in the insertion direction) of each receptacle, each side wall 1 13 has an opening 1 18 which has from the outside to the inside and which also has a portion with a reduced wall thickness on the inside of the side wall 1 13. In the area of each receptacle, a fixing element 120 is additionally attached to the base frame 1 1 1.

The fixing element 120 comprises two fixing arms 121, which are connected to each other, and that - in this embodiment - such that the fixing between see the boundaries 1 17 extends so that by a positive connection in the plane defined by the side wall 1 13 between the boundaries 1 17 and the fixing 120 it is fixed in this plane. In this case, however, the fixing arms 121 can move within the recess 1 16 with a corresponding deformation of the fixing element 120. In the middle of the fixing element 120 formed of rectangular wire, this has a clamping piece 122 that extends through the opening 1 1 8 in the side wall 1 13 and rests on the outside of the side wall in the section with the reduced wall thickness on the wall, so that the relative relationship of clamping piece 122 and remaining fixing element 120 to each other, the fixing element is held on the side wall. At the ends of the fixing arms 121 of the fixing element 120 extending opposite to the direction of insertion there is in each case a fixing hook 123, which is formed by bending the wire in an approximate triangular shape and has an edge 124 and a shoulder 125. Between the fixing arms 121, in particular between the shoulders 125 and the stop 1 14 of the base frame, there is a latching area 126 for receiving the respective latching nose 91 of a module 9.

If the module 9 is inserted into the holding frame 1, the locking lugs 91 come between the guides 1 15 of the base frame 1 1 1 and then get to the fixing hooks 123 of the fixing arms 121 of the respective fixing 120. By a certain amount of force in the continuation of insertion are by the latching noses 91, which each slide along the flanks 124, deform the fixing arms 121, wherein the fixing hooks 123 are moved laterally in the direction of the module 9. When the respective locking lug 91 has completely passed the fixing hooks 123, no force maintaining the deformation of the fixing arms 121 acts more on the fixing hooks 123 or fixing arms 121 and the fixing arms spring back into a position as can be seen approximately in FIG , It should be noted that a plastic deformation is possible, but then a corresponding action of a user is necessary to effect the return of the fixing arms. With a latching nose 91 of a module 9 in the latching area 126, the shoulders 125 and the stop 14 close the latching lug so that a forward and backward movement of the module 9 in the insertion direction is not possible or only to a very limited extent. By the contact of the guides 1 15 with the latching nose 91, this is also set 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 1 13 from each other, a movement of the module 9 can be prevented or limited in the longitudinal direction, so that the module 9 is fixed in three spatial directions.

The fixation of the module 9 in the holding frame is detachable, as far as from the outside there is a possibility of acting on the fixing arms 121 to remove the fixing hooks 123 in front of the locking lug 91 of the module (by corresponding bending of the fixing arms 121).

Preferably, the shoulder 125 has a slight incline in the direction of the fixing arm 121, so that when the force is applied against an inserted module 9 with a certain deformation of the fixing element 120, the shoulder 125 comes to lie flat on the surface of the locking lug better to suppress further bending.

However, it is also possible that the paragraph has a slope in the opposite direction, so that a bending of the fixing is possible with a correspondingly large force even without damaging the support frame. Fig. 4 shows a view of a holding frame according to a second embodiment of the invention with modules.

The inventive method is used for equipping a holding frame (as provided for example in the embodiments discussed above) for a connector for receiving similar and / or different modules with a module.

For this purpose, the method has a step S1 of inserting the module into a base frame. This base frame defines a plane transverse to an insertion direction of the module in the holding frame and has mutually opposite end faces and side walls (see above). In a part of the insertion S2, a locking lug of the module passes (step S2) a portion of a fixing arm of a fixing member attached to a side wall of the base frame and for deformation between an insertion state allowing insertion of the module in the insertion direction into the support frame , and a holding state in which an inserted module is fixed by the latching lug of the module and the fixing element at least along the insertion direction.

In connection with the insertion S2, a widening (step S3) of the portion through which the locking lug passes, so that finally one of the insertion state (step S4) is established. The fixing element is in passing state (S4) when passing (S2) at least at one moment. After passing (S2), the method includes spring-back (step S5) of the fixing member from the insertion state to the holding state (step S6).

As already explained above, the deformation S5 (as well as the widening S3) comprises a movement of at least the fixing arm of the fixing element in the longitudinal direction of the side wall. After a module is inserted and held in the hold state, the process may be repeated for another module until the entire support frame is populated.
