Description

Shielded Plug Connectors

technical field

The invention relates to a shielded plug connector with a shielding transmission element according to claim 1 .

Background technique

In the technical field of electrical contacting of electrical and/or electronic devices, in particular for the connection of devices requiring electrical shielding, different solutions are known for transferring the shielding of the involved plug-in connector pairs.

Some known plug connectors have been developed for specific applications and cannot be easily or not transferred to other applications due to the high demands on electrical shielding and sealing against media, especially against moisture superior.

WO2006/013027A discloses a shielded high-current plug connector.

EP1965467B1 also discloses a plug-in connector having at least one end-side insertion opening at which a wire-shaped shield is transferred to a corresponding mating connector.

Plug connections known from the prior art have circular or oval plug connectors and thus structures in which the plug connectors have corresponding circular or oval shaped Plug section. The shield transmission element can be mounted on these round or oval plug sections in a force-fit manner. In particular if the shielding transmission element is designed as a spring element, the shielding transmission element can be fitted by means of a circular plug section, so that the spring element or the shielding transmission element bears against the periphery of the plug section in a non-positive manner.

In some applications, however, rectangular plug connectors must be used instead of circular plug connectors. In the context of the present invention, rectangular plug connectors are understood to mean all plug connectors or plug connector housing shapes in which at least one linear plug is present on the plug connector or on the plug connector housing segment. In the simplest case, a rectangular plug-in connector has four linear plug-in sections, two of which lie opposite each other in pairs and are connected to one another at their corners. The corner connection is usually implemented as a rounded corner.

However, a problem with such plug connectors is that the shape-unstable shield transfer element is difficult to position on a linear (ie straight) section. In this case, problems arise for the shielding transmission element in the region of the linear section, since it hangs down especially in the lower section. At least the non-positive abutment/contact of the shield transfer element on the plug-in connector housing or on the plug-in connector is problematic. The longer this linear plug-in section is, the stronger the aforementioned effect occurs. In the most unfavorable case, for example at the bottom of a rectangular plug connector, the shield transfer element hangs down so much that the shield transfer element no longer touches the outer side of the plug section at all, and in this case and state, The connection of the plug-in connector pair becomes impossible, or the pendant shield transfer element is damaged when forming the plug-in connection.

Contents of the invention

It is therefore the object of the present invention to provide a shape-unstable shield transmission element and a plug-in connector with such a shield transmission element, which overcomes the above-mentioned disadvantages and which in the region of the linear plug section according to abut against the housing in the prescribed manner.

This object is achieved by the features of claim 1 .

Advantageous developments of the invention are given in the dependent claims.

The invention is achieved in that the shielding transmission element is designed as a flexible, resilient element composed of several sub-elements, so that the sub-elements are connected to each other and form a plurality of Fastening openings for fastening elements.

Furthermore, corresponding openings and/or holes are provided on the plug connector and/or on the plug connector housing, which openings and/or holes can be aligned with the fastening openings of the shield transmission element.

According to the invention, the fastening element is arranged on the fastening opening of the shield transmission element in such a way that the fastening element can be pressed into the opening on the plug-in connector housing. Depending on the geometry and length of the linear plug section area, one or more openings can be provided and thus one or more fastening elements can be proposed.

This makes it possible to use a flexible, elastic shield transmission element in the corresponding area, while at the same time a form-fitting contact with the outer contour of the plug-in connector housing can be achieved in the area of the linear plug-in section .

In a particularly preferred embodiment, the foil strip is designed as an s-shaped or serpentine curved metal strip with curved foil sections. These curved lamellar sections can be formed in guide ribs provided on the plug-in connector housing, thus ensuring a lateral support of the shield transfer element in and/or against the plug-in direction.

Advantageously, for fastening with fastening elements, the lamella opening is realized as a linear array of holes, so that the shielding transfer element can be fitted in any position.

In a particularly preferred refinement of the invention, the fastening element is designed as a press-in element with a press-in section.

Correspondingly, corresponding openings in the plug-in connector or in the plug-in connector housing are formed such that the press-in element can be inserted into the corresponding opening in a non-positive and/or form-fitting manner.

This ensures a particularly high-strength connection between the shield transfer element and the plug-in connector, which connection can also withstand high mechanical stresses when the plug-in connector is plugged in or pulled out.

By selecting the material, the distance of the holes and the openings, an optimum matching to the geometry of the corresponding plug connector can be obtained.

The shielding transmission elements are advantageously designed as lamellar elements which comprise a plurality of adjacently arranged lamellar arcs. Every two adjacently arranged lamination arcs are connected to one another by means of a connection section, while a fastening opening is formed directly between the lamination arc and the connection section.

Adjacent lamination arcs connected to one another are connected at their opposite end to the respective adjacent lamination arc by means of a further connecting section. This also happens when another fastening opening is formed. The foil arcs are thus connected to each other in an s-shape by means of the connecting sections and form a flexible foil strip.

Advantageously, the foil strip has between every two adjacent connecting sections a region which is shaped in such a way that it serves as a fastening opening. Thus, an array of fastening openings is formed on both sides of the foil strip, with which fastening can be achieved by means of press-in pins.

Due to this "dense" (opening) array, it is not necessary to stretch the foil in a certain section in order to contact the periphery during assembly when assembling the foil strip which is placed around the plug connector or its plug connector section with pieces.

In contrast, due to the dense array of holes, a matching fastening opening can always be found in the plug-in connector housing in the vicinity of the fastening hole, which fastening opening is accordingly arranged in the immediate vicinity of the hole.

In this way, in order to align the fastening opening with the adjacent fastening hole, it is not necessary to stretch the partially secured foil strip by an excessive distance in its longitudinal direction.

Depending on the size and precision-related requirements, the number of sheet arcs can be matched to the respective application. For particularly high precision standards, a large number of thinner lamellar arcs can be interconnected, resulting in a correspondingly denser fixed array of fastening openings.

Detailed ways

The same components and components with the same function are denoted by the same symbols in the figures.

FIG. 1 shows an exemplary embodiment of a plug connector 1 according to the invention with a shield transfer element 4 .

However, only the front side plug section 3 of the plug connector 1 is shown.

The plug section 3 has a substantially flat receiving region 32 extending circumferentially around the plug section 3 . A circumferential contour 35 is provided on the plug-side end 34 . Furthermore, guide ribs 5 are provided in the region of the plug section 3 , with which the shield transmission element 4 can be arranged in contact. Optionally/alternatively, however, guide ribs or guide grooves 5 can be arranged in a more rearward region at a distance from the circumferential contour 35 .

It can be clearly seen in FIGS. 1 and 2 that the plug connector has at least one linear plug section region 30 . Fastening holes 40 are provided in the region of the linear plug, as shown in FIG. 3 .

In FIG. 1 the shield transfer element 4 is attached to the plug section 3 of the plug connector housing 2 by means of two fastening elements 7 .

FIG. 2 shows a partial sectional view of the assembled arrangement of the partially shown upper part of the plug-in connector housing 2 above which the shield transfer element 4 is arranged.

By way of example, two fastening elements 7 are shown as press-in elements located above the shielding transmission element 4 . To assemble the shielding transfer element 4 , as shown in FIGS. 2 and 3 in the pre-assembly position, the shielding transfer element 4 is moved into the position shown in FIGS. 1 and 5 . To this end, it is necessary to align the fastening opening 8 a of the shield transmission element 4 with the fastening hole 40 in the plug section 3 .

FIG. 3 shows in detail the shielding transfer element 4 designed as a foil strip.

In the embodiment shown here forming a foil strip is particularly advantageous because the foil strip is flexible and can therefore be drawn to cover the edge of the flange 35 by corresponding longitudinal stretching in the z-direction. surface.

After the foil strip 4 has been assembled, the foil strip 4 can spring back into its initial state in its final assembled position. In this position, the foil strip loosely surrounds the plug connector housing 2 in the region of the plug section 3 and indeed in the receiving region 32 and can surround the plug connector housing in the peripheral direction. Body 2 moves. Thus, it is possible to align the fastening opening 8 a with the fastening hole 40 on the plug connector housing 2 during assembly. As soon as the fastening opening 8 a is made available due to the displacement or movement of the foil strip 4 into its defined position, the foil strip 4 can be fastened to the plug connector housing 2 by means of the press-in element 7 .

Advantageously, the laminar belt 4 comprises a plurality of laminar elements 6 . Each lamellar element 6 comprises a curved lamellar section, referred to below as a laminar arch 9 . When the fastening opening 8 a is formed, in each case two adjacent lamination arcs are connected to one another at their first ends by means of a connecting section 10 .

It can be clearly seen from FIG. 3 that the connection section 10 can be designed as a curved connection section. The connection section 10 is arranged as a curved web 50 on the lamination arc 9 . The recesses 50 a , 50 b are located in the immediate vicinity of the junction between the lamellar arch 9 and the connecting web 50 . In this case, the first recess is formed in the region of the connection web 50 and the first lamination arc 9 , while the second recess 50 b is formed in the region of the connection of the connection web 50 and the second lamination arch 9 .

Due to the curved design of the connecting tab 50 , a recess 50 c forming part of the fastening opening 8 a is provided.

Optionally/alternatively, the notch 50c can also be designed as a rectangular or other recess-like notch on the connection tab 50, thereby thereby providing a connection tab 50 located adjacent to and connected to the lamina arc 9 between fastening openings 8a. The fastening opening 8a is sized such that it matches the size of the fastening hole 40 and substantially coincides with its diameter.

It can also be seen from FIG. 3 that the respective other ends of two interconnected lamellar arcs 9 are connected to their respective adjacent laminar arches 9 by means of the same connecting tab 50, so that each laminar arch 9 is connected to one of its The ends are connected to the adjacent lamination arc 9 by means of connecting webs 50 , while a fastening opening 8 a is formed in each case.

Due to the adjacent recesses 50a, 50b, a fastening opening 8b is likewise provided between the two connecting webs 50, the fastening opening 8b having a shape similar to the fastening opening 8a. An array of holes with a distance D is thus provided. Thus, the hole array of the fastening opening 8a has a distance 2D. The same applies to the distance of the fastening opening 8b, which likewise has a 2D hole array distance. Since the first hole array 8a is at a distance D from the second hole array 8b, a hole array with a hole distance D results in total. Even when the fastening holes 40 have tolerances with respect to the fastening openings 8a, 8b in the thin-film strap 4, this so-called double hole array enables fitting with a correspondingly small stretching of the thin-film strap .

The fastening element 7 is advantageously designed as a press-in element 7 with a pin region 7 a and a head 7 b formed on the pin region. The head forms at least one holding section 7c, which is preferably designed as a linear holding section 7c. Alternatively/alternatively, a mushroom-shaped or half-mushroom-shaped head 7b may also be used. In the pin area 7 a there is at least one fastening section 7 d whose geometry and thus its diameter are enlarged compared to the diameter of the fastening hole 40 .

Advantageously, the fastening element 7 and thus the press-in element 7 is designed as a press-in element formed from a sheet metal. By having a flat design of the two plane-parallel side surfaces, the press-in element 7 can be deformed when it is pressed into one of the fastening holes 40 , whereby the fastening section 7 d is displaced in the fastening hole by means of the material. 40 is internally deformed so that a positive and/or force-fit connection between the press-in element 7 and the plug connector housing 2 is produced.

Advantageously, the material of the foil strip 4 is produced as an electrically conductive, elastic sheet.

The press-in element 7 is advantageously designed as a T-shaped fastening element made of a deformable material.
