Description

Buckle module for plug connector component

Technical Field

The utility model relates to a snap-on module according to the utility model for a plug connector part which can be connected to a mating plug connector part, and to a corresponding mating snap-on module.

Background

In practice, plug connectors are often provided with snap-in means in order to prevent, for example, a plug connector part (such as a plug or a socket) of the plug connector from being separated by mistake from a corresponding counter-mating plug connector part (such as the other of the plug or the socket) of the plug connector.

DE 102006054648B 4 describes a plug-type connector coupling having two connectable plug housings which can be connected by means of snap-on members provided on the narrow sides of the housings. This snap member comprises a clasp molded on one of the plug housings and a correspondingly designed catch tongue.

DE 102012011676 a1 describes a terminal block with a plurality of terminal blocks, wherein the respective terminal blocks of the terminal block can be laterally snapped onto one another. Furthermore, a closure having a housing wall is described.

Furthermore, it is known to open the snap mechanically, for example with the aid of a tool, in order to disengage the snap connection.

EP 2953212B 1 describes a plug connector arrangement in which resilient latching tongues formed on the insulating housing of a mating plug connector part can be latched with corresponding latching elements of the plug connector part. Furthermore, a separating element is provided in order to facilitate the renewed separation of the catch.

SUMMERY OF THE UTILITY MODEL

The object of the utility model is to further improve the snap connection of a plug connector.

The solution of the utility model to achieve the above object is a snap module for a plug connector part according to the utility model.

In view of this, a latching module for a plug connector part which can be electrically connected in particular to a mating plug connector part is provided, wherein the latching module can be mounted on the plug connector module of the plug connector part in such a way that at least one latching element of the latching module can be elastically deformed by a mating latching element arranged on the mating plug connector part in order to latch with the mating latching element, in particular detachably.

The snap-on module can be mounted on the plug connector module, i.e. constructed independently of the plug connector module, in particular independently of the remaining plug connector components and independently of the electrical contact components or the optical contact components. This makes it possible to optionally equip the plug connector part with snap modules or to remove snap modules without the need for snap. This allows particularly flexible use of the snap module. This makes it possible to provide a kit with a snap module and a plug connector module, wherein the plug connector with or without the snap module can be selectively provided by an assembly of the kit. The plug connector module comprises, guides and/or carries, for example, electrical or optical conductors.

In one embodiment, the fastening module is disc-shaped, in other words, plate-shaped. In this case, the snap module extends in particular substantially in a plane. The snap modules extend for example mainly in two of the three spatial directions. This solution enables a modular structure that can be used particularly flexibly.

The snap module may have a main extension plane, wherein the at least one snap element may be elastically deformable within the main extension plane. The desired elastic deformation of the snap element causes a displacement of at least one section of the snap element relative to at least a part of the remaining snap module, wherein this displacement is carried out in a main extension plane. That is, the snap-fit with the counterpart snap element does not result in a displacement of the snap element or the section of the snap element out of the main extension plane. The snap-in module therefore requires only a relatively narrow installation space for the snap-in, so that the integration with the other components of the plug connector is greatly simplified.

Optionally, the snap module comprises two snap elements. Wherein a counter snap element can be introduced between the two snap elements for snapping. This enables a particularly secure and symmetrical snap-on. During the introduction, the snap elements are pressed away from each other, for example, by the counter-snap elements.

The at least one catch element is designed, for example, as a clasp. If two snap elements are provided, these are each embodied, for example, as a clasp, in particular as a clasp facing each other.

The snap module optionally comprises two opposite outer surfaces between which at least one snap element, in particular two snap elements, is arranged. The outer surfaces extend, for example, at least partially, substantially or completely parallel to each other. The snap elements are for example built-in. The catch element can be moved at least partially relative to these outer surfaces, for example, by elastic deformation caused by the mating catch element. Thus, the outer surface may protect the snap element. Furthermore, in particular in the case of a snap-in process, where the outer surfaces are all rigid, the mounting and the arrangement on the plug connector part can be simplified.

Optionally, the snap module comprises at least one form-fitting element for form-fittingly holding the snap module on the plug connector module and/or on another snap module. The form-fitting element can be snapped together with a mating form-fitting element. This makes it possible to mount the plug connector part particularly easily, while the snap-on module is held firmly on the remaining plug connector part.

According to one aspect, a plug connector part is provided for electrical connection with a mating plug connector part, in particular. The plug connector part comprises at least one snap module (in particular a plurality of snap modules) as described in any of the solutions described herein.

By modularly constructing the snap modules, it is possible to provide a plurality of variants of the plug connector part with different plug-in forces and/or pulling forces, for example by correspondingly selecting at least one snap module from a plurality of mutually different snap modules when assembling the plug connector part. The construction of the remaining components of the plug connector part can be kept unchanged and, if required, snap modules can be selected.

At least one plug connector module of the plug connector can have the same or substantially the same outer contour as the latching module. Thus, one or more plug connector modules can be assembled (e.g. stacked) together with one or more snap modules and mounted together, for example on or in a common housing which provides an optionally identically shaped abutment face for the snap modules and the plug connector modules. The (identically constructed) outer contour can extend, for example, over a section and/or over one or more side faces. Optionally, the at least one plug connector module and the at least one snap module have in-plane encircling envelopes of identical configuration.

According to one aspect, a mating snap module is provided that can be snapped with the snap module. The mating snap-fit module is suitable, for example, for a mating plug-in connector part which can be electrically connected to a plug-in connector part, wherein the mating snap-fit module is designed to be mountable on a mating plug-in connector module of the mating plug-in connector part in such a way that a mating snap-fit element of the mating snap-fit module can elastically deform at least one snap-fit element of a snap-fit module, which is mounted on the plug-in connector part, as described in any of the embodiments described herein in order to snap-fit, in particular detachably, with the snap-fit element.

The mating connector module comprises, guides and/or carries, for example, electrical or optical conductors.

According to one aspect, a snap arrangement is provided, comprising at least one snap module according to any of the claims described herein and at least one counterpart snap module with counterpart snap elements, in particular the aforementioned counterpart snap module.

The snap means may have the same number of snap modules and mating snap modules. Optionally, the snap means comprises a plurality of snap modules and a corresponding plurality of mating snap modules.

In one technical solution, the snap module and the mating snap module are both plate-shaped/disc-shaped. Furthermore, at least one snap element (only) can (be) snapped with a counterpart snap element (in particular) if the snap module and the counterpart snap module are arranged in the same plane. Optionally, the snap modules and the mating snap modules have the same thickness.

The snap module and the counterpart snap module can be constructed such that the counterpart snap element can be snapped with the at least one snap element (by means of a relative movement) along the plugging direction, wherein the at least one snap element of the snap module can be elastically deformed in a plane parallel to the plugging direction. The latching device can thus be designed particularly flat and can be arranged particularly simply on the plug connector and the counter-plug connector.

According to one aspect, a plug connector is provided. The plug connector comprises a plug connector part and a counter-mating plug connector part which can be electrically connected to the plug connector part. Furthermore, the plug connector comprises a snap device according to any of the claims described herein.

According to one aspect, a method of assembling a plug connector component is provided. The method comprises the following steps: providing at least one plug connector module; providing at least one snap module as in any of the technical solutions described herein; and mounting the at least one snap-on module on the at least one plug connector module.

Accordingly, according to one aspect, a method of assembling a mating connector part is provided. The method comprises the following steps: providing at least one mating plug connector module; providing at least one mating buckle module; and mounting the at least one mating snap module on the at least one mating plug connector module.

The method can be improved by assembling the male connector part and the counter-mating connector part in the above-described manner to produce a plug connector.

In the method, the insertion force and/or the pulling force can be predetermined. The number of snap modules (and/or mating snap modules) may be determined therefrom, wherein in the step of providing at least one snap module (or mating snap module), the determined number of snap modules (or mating snap modules) as described in any of the solutions described herein are provided.

This makes it possible to provide a kit for assembling a plug connector part and/or a mating plug connector part, which can be used to form different variants of a plug connector with different plugging forces and/or pulling forces.

Detailed Description

Fig. 1A to 2B show a snap arrangement 1 with (exactly) one snap module 10 and (exactly) one counterpart snap module 11. The snap-on module 10 can be mounted on a plug-type connector module of a plug-type connector part which is described in more detail below. Correspondingly, the mating snap-on module 11 can be mounted on a mating connector module of a mating connector part, wherein the connector part and the mating connector part together form a connector, for example in the form of a plug and a socket.

The snap module 10 and the counterpart snap module 11 are both flat, in particular disc-shaped. Wherein the snap module 10 and the counterpart snap module 11 each extend substantially in one plane. The dimensions of the snap modules 10 and the counterpart snap modules 11 in the direction perpendicular to this plane are much smaller than in the two spatial directions within the plane. This plane may also be referred to as the main extension plane.

The snap module 10 comprises two

snap elements

100A, 100B in the form of clasps. The two clasps (snap

elements

100A, 100B) are facing each other with their hook-shaped ends aligned with each other. The two

snap elements

100A, 100B project from the base 105 of the snap module 10 at an angle to each other. In the embodiment shown, this angle is 30 to 40 degrees, wherein other values may also be used. The

snap elements

100A, 100B define between them a (here triangular) socket for a counterpart snap element 110 of a counterpart snap module 11. The hook-shaped ends of the two

catch elements

100A, 100B are spaced from each other, thereby defining an opening for the socket.

As shown in fig. 1B, if the snap module 10 and the counterpart snap module 11 are arranged in the same plane, the counterpart snap module 11 can be moved to the snap module 10 in the plugging direction R so that the snap module 10 snaps with the counterpart snap module 11. Wherein mating snap element 110 is inserted between

snap elements

100A, 100B. Upon insertion, the counter snap element 110 elastically pushes the

snap elements

100A, 100B apart, in other words, causes them to bend away from each other. In order to achieve the highest possible stability and the longest possible service life, a cutout 106 is formed in the base of the

snap elements

100A, 100B, which cutout 106 is locally rounded. The base of the

snap elements

100A, 100B abuts the base 105. On the cut-out 106, the cross-section of the

snap elements

100A, 100B is reduced with respect to the adjacent section and the section remote from the base 105. Thus, the

snap elements

100A, 100B are bendable, in particular on their section adjoining the base 105.

If the counter-catch element 110 is inserted sufficiently far, the hook-shaped ends of the

catch elements

100A, 100B snap into the undercuts of the counter-catch element 110 and latch the catch module 10 with the counter-catch module 11.

The snap module 10 further comprises two

protrusions

104A, 104B arranged adjacent to the

snap elements

100A, 100B. The

snap elements

100A, 100B are arranged between the

protrusions

104A, 104B. The

projections

104A, 104B comprise one

outer surface

101A, 101B of the snap module 10, respectively. The two

outer surfaces

101A, 101B are arranged on opposite sides of the snap module 10. The two

outer surfaces

101A, 101B are narrow sides of the snap module 10, between which narrow sides two wide sides of the snap module 10 extend.

Thus, the

snap elements

100A, 100B (in terms of main extension plane) are arranged inside the snap module 10. The

projections

104A, 104B are flush with the

snap elements

100A, 100B (on the plugging side) or project (slightly) with respect to these snap elements. In order to enable the

snap elements

100A, 100B to elastically yield, a gap is formed between each

snap element

100A, 100B and the respectively

adjacent projection

104A, 104B by forming a gap.

By means of the built-in

snap elements

100A, 100B, the outer contour of the snap module 10 is not changed when snapping-in with the counterpart snap module 11. The outer contour (substantially) describes a rectangle in the main extension plane and (substantially) a cube in space. Thereby, a particularly flexible insertion solution of the snap means 1 is formed. The snap module 10 can be mounted fixedly inside the housing, for example. It is also possible to fasten the snap module 10 on the plug connector part with one or more externally acting clips. For this purpose, form-fitting elements in the form of recesses 102 are formed on the

outer surfaces

101A, 101B, which in the exemplary embodiment shown are also provided with optional grooves. This enables a secure and positionally fixed mounting of the snap module 10.

The mating buckle module 11 comprises a base 111 from which the mating buckle element 110 protrudes. The mating snap element 110 is here constructed in the form of a tenon. The mating snap element 110 protrudes from a stop surface 113 built on the base 111. When the mating snap element 110 is inserted between the two

snap elements

100A, 100B of the snap module 10, the stop surface 113 stops on the ends of the

snap elements

100A, 100B when the snap-in final position is reached. The mating snap element 110 is arranged here eccentrically on the stop surface 113, wherein it can likewise be arranged centrally.

If the

snap elements

100A, 100B and the counterpart snap element 110 are intended to snap into each other, the snap module 10 and the counterpart snap module 11 are arranged in the same plane. Thus, only one common main extension plane H is depicted in fig. 2B, which comprises the main extension planes of the snap modules 10 and the counterpart snap modules 11.

The insertion force required for the snap-fitting of the

snap elements

100A, 100B with the counter-snap element 110 is for example dependent on the material and material thickness of the

snap elements

100A, 100B and the counter-snap element 110, in particular also on the shaping thereof. The construction of the lead-in ramp is particularly important.

As can be seen in particular from the detail a of fig. 1A shown enlarged in fig. 3, the

snap elements

100A, 100B have an internal lead-in chamfer 107. The angle between the lead-in chamfer 107 of one snap element 100A and the lead-in chamfer of the other snap element 100B, which is close to a straight angle, for example, results in a greater plugging force than a more acute angle. The same is true for the opposing lead-in ramps 114 on the mating snap element 110, see in particular detail section B of fig. 1A shown enlarged in fig. 4.

The pulling force required to separate the snapped snap element from the

counterpart snap element

100A, 100B, 110 is in particular related to the construction of the snap surfaces 108, 116 of the snap element and the

counterpart snap element

100A, 100B, 110. In the latched state, the latching surfaces 108 of the

latching elements

100A, 100B catch behind the latching surfaces 116 of the mating latching element 110. The catch faces 108, 116 of the

catch elements

100A, 100B and/or the counter catch element 110 (i.e. the

catch elements

100A, 100B and the counter catch element 110 in the example shown) are not perpendicular, but are slightly inclined towards the plugging direction R, in particular in a manner such that they can be separated. The inclination of these snap surfaces 108, 116 affects the strength of the pulling force. The latching surfaces 108, 116 are designed such that the pulling force is greater, in particular much greater, than the insertion force. Alternatively, the two forces may be equal.

On the basis of the modular construction of the snap-on device 1, a plurality of alternative variants of the snap-on device 1 can be provided for the same plug-in connector for selection, wherein variants which achieve a predetermined plugging force and/or pulling force can be selected.

The snap modules 10 and the counterpart snap modules 11 have the same thickness or substantially the same thickness (in particular material thickness) in a direction perpendicular to the respective main extension plane H. The snap module 10 is integrally formed. The mating snap module 11 is likewise integrally formed here. The snap module 10 and/or the mating snap module 11 are constructed, for example, as stampings or injection-molded parts.

Fig. 5A and 5B show a buckle device 1, but here with a plurality of buckle modules 10 and a plurality of counterpart buckle modules 11. Here, the number of snap modules 10 is the same as the number of mating snap modules 11. In the example shown, four snap modules 10 and four mating snap modules 11 are provided. A plurality of snap modules 10 abut against each other. The snap modules 10 (respectively the counterpart snap modules 11) form a stack.

By increasing or decreasing the number of snap modules 10 and counter snap modules 11, the plugging and pulling forces can be increased or decreased in a particularly simple manner with the use of identical parts.

The snap modules 10 are fixed to each other by two frames 12. The frame 12 snaps into the recesses 102 on the opposing

outer surfaces

101A, 101B. The mating snap modules 11 are fixed to each other by two frames 13 which snap with projections 112 built on opposite outer surfaces.

Fig. 6A and 6B show a buckle device 1' which is constructed similarly to the buckle device 1 shown in fig. 5A and 5B, and therefore only the differences will be explained below.

The snap-on device 1 'comprises snap-on modules 10', which, unlike the snap-on modules 10 in fig. 1A to 5B, have form-fitting elements, here in the form of tenons 103, on a (larger) side. The side with the tenon 103 extends between the

outer surfaces

101A, 101B on the

projections

104A, 104B. The tenon 103 is adapted to snap-fit with a corresponding socket on an adjacent snap module 10' (obscured in the view of fig. 6A and 6B) or an adjacent plug connector module. Alternatively, the frame 12 may also be mounted corresponding to fig. 5A and 5B.

Furthermore, the snap-on device 1 'comprises mating snap-on modules 11', which, unlike the mating snap-on modules 11 in fig. 1A to 5B, have form-fitting elements, here in the form of tenons 115, on the (larger) side. The tenon 115 is adapted to snap-fit with a corresponding socket on an adjacent mating snap module 11' (obscured in the view of fig. 6A and 6B) or an adjacent plug connector module. Alternatively, the frame 13 may also be mounted corresponding to fig. 5A and 5B.

Fig. 7 shows a plug connector 2 with a plug connector part 20 and a mating plug connector part 21. The male connector part 20 and the mating male connector part 21 can be plugged together to establish an electrical connection.

The plug connector part 20 comprises a plug connector module 200 on which projecting contacts 201 (in the form of blade contacts) are mounted and which has

sockets

202, 203 for cables to be connected and optionally for tools on the side facing away from the projecting contacts 201. The plug connector part 20 further comprises the snap module 10 in fig. 1A-5B. The plug connector module 200 and the snap module 10 are fixed together by means of a frame 12.

The mating plug connector part 21 comprises a mating plug connector module 210 and the mating snap module 11 in fig. 1A-5B. The counter-mating connector module 210 has openings 211 for the projecting contacts 201 of the plug connector module 200. The contacts 201 can be inserted into the openings 211 in the plugging direction R to establish an electrical connection. The mating plug connector module 210 and the mating buckle module 11 are fixed together by means of a frame 13.

The plug connector 2 can comprise a plurality of plug connector modules 200 and mating plug connector modules 210, which can be assembled, for example, into a plug connector cascade. The snap modules 10 and the mating snap modules 11 can be arranged at a plurality of (optionally arbitrary) positions beside and between the plug connector module 200 and the mating plug connector module 210.

Fig. 8 shows a method for assembling the plug connector part 20, comprising the following steps:

step S1: providing at least one plug connector module 200;

step S2: providing at least one snap module 10; 10'; and

step S3: -placing said at least one snap module 10; 10' are mounted on the at least one plug connector module 200.

Accordingly, a mating plug connector part 21 can be assembled, wherein a corresponding mating assembly is applied.

The plug connector is provided by manufacturing a plug connector part 20 and a mating plug connector part 21.

The plugging and/or pulling force can be preset prior to the assembly of the plug connector part 20 and/or the mating plug connector part 21. Subsequently, the snap module 10 is selected accordingly; 10' and a mating snap module 11; 11' (in particular the steepness of the lead-in chamfer and the snap surface) and/or the number. For example, a larger number is selected for larger insertion forces and pulling forces than for smaller insertion forces and pulling forces. In this way, a plurality of variants of the plug connector 2 can be provided in a modular construction in a particularly simple and flexible manner using congruent parts.

Furthermore, the snap-in device 1; the modular construction of 1' makes it possible to selectively provide the same type of plug connector 2 with or without a snap-in element. Wherein the same components may always be applied. Optionally, as a snap module 10; 10' and/or mating snap modules 11; 11', a non-snap type placeholder is used.

For a plug connector with a predetermined plug connector part 20 and a mating plug connector part 21, the latching device 1; 1' can also be set conveniently in such a way that there is a perceptible resistance when manual insertion is carried out, for example to improve the tactile feel.

The pulling force can be set such that the plug connector is firmly engaged, but can also be manually disengaged, in particular without the use of tools.
