Description

Field of the invention

The invention relates to a connector, a method for producing a connector. The invention further relates to a connector assembly.

State of the art

From the prior art, e.g. for automotive applications, electrical connectors are known which can be mated with complementary mating connectors to form a connector assembly. In order to protect contact elements in an interior of such a connector assembly (i.e., in the mated condition) from fluid media (e.g., gases and / or liquids) from an external environment of the connector assembly, a sealing element is often used e.g. arranged on the connector. In the assembled state of connector and mating connector, this sealing element is then arranged between these two components and ensures the seal. It may be in the sealing element, e.g. to act a radial sealing element, ie a sealing element which causes the sealing in a radial direction perpendicular to the insertion direction. This can be advantageous, since in this way no particularly large contact pressure must be exerted along the insertion direction between the connector and mating connector in order to ensure the seal. Rather, e.g. a mating connector outer wall e.g. be cup-shaped and engage over the radial sealing element. By a suitably selected dimensioning can be effected in the radial direction between the radial sealing element and the mating connector outer wall so a kind of interference fit and done in this way the seal.

A connector with such a radial sealing element or such a radial seal and a connector assembly with such a radial sealing element are known from DE 200 05 090 U 1 known.

Disclosure of the invention

The invention is based on the recognition that the sealing element, preferably the radial sealing element, may be arranged as an initially separate element on or in the connector, e.g. by being slipped over a wall of a connector housing of the connector in the manner of a sealing ring. In such an embodiment of the sealing element or the radial sealing element, it may happen that the sealing element dissolves during transport or handling of the connector and falls out. It can also happen during mating of connectors and mating connectors and a subsequent separation of the two components that the sealing element or the radial sealing element is twisted in itself, since it is entrained some distance along the insertion direction of the mating connector. It may also happen that within a certain maintenance interval, the sealing element or the radial sealing element must be checked for damage and must be removed for this purpose again from the connector - if it is still okay it should be placed on or in the connector again.

It may therefore be a need to provide a connector that allows easy and damage-free assembly and disassembly of a sealing element or radial sealing element on or in the connector, while ensuring that during transport or handling of the connector, the sealing element or the radial sealing element is not lost or substantially removed from its desired position. In addition, it should be ensured that when plugging and unplugging connectors and mating connectors, the sealing element is not twisted in itself or slipping locally along the direction of insertion. In other words, it is intended to provide a connector which is easy to assemble and maintain, and which allows a permanent seal of an interior in the mated state with a mating connector.

Advantages of the invention

This need can be met by the subject matter of the present invention according to the independent claims. Advantageous embodiments of the present invention are described in the dependent claims.

• -- ein Steckverbindergehäuse;
• -- ein Kontaktelement, welches am oder im Steckverbindergehäuse angeordnet ist;
• -- ein Schirmblech, welches das Kontaktelement zumindest abschnittsweise umgibt;
• -- ein Dichtelement, bevorzugt, ein Radialdichtelement, zur Abdichtung des Kontaktelements bzw. eines Innenraums in einem zusammengesteckten Zustand von Steckverbinder und Gegensteckverbinder. Dabei kann das Kontaktelement z.B. gegen eine Außenumgebung des Steckverbinders abgedichtet werden. Das Kontaktelement kann z.B. in einem Innenraum des Steckverbindergehäuses oder in einem radial innen liegenden Bereich des Steckverbindergehäuses angeordnet sein.

Das Dichtelement bzw. das Radialdichtelement umläuft eine Wandung des Steckverbindergehäuses in einer Umlaufrichtung um die Einsteckrichtung herum, wobei von dem Schirmblech eine Lasche entlang einer radialen Richtung senkrecht zur Einsteckrichtung abragt. Die Lasche ist entlang der Einsteckrichtung betrachtet stromabwärts des Radialdichtelements angeordnet, wobei die Lasche das Dichtelement bzw. das Radialdichtelement in einem Überdeckungsabschnitt in radialer Richtung zumindest teilweise überdeckt.According to a first aspect of the invention, a connector for mating along a plug-in direction with a mating connector is proposed. The connector has:

• a connector housing;
• - A contact element which is arranged on or in the connector housing;
• - A shield plate which surrounds the contact element at least in sections;
• a sealing element, preferably a radial sealing element, for sealing the contact element or an interior in a mated state of the plug connector and Mating connector. In this case, the contact element can be sealed, for example against an outside environment of the connector. The contact element may be arranged, for example, in an interior of the connector housing or in a radially inner region of the connector housing.

The sealing element or the radial sealing element circumscribes a wall of the connector housing in a circumferential direction about the insertion direction, whereby a tab projects from the shielding plate along a radial direction perpendicular to the insertion direction. The tab is arranged along the insertion direction downstream of the radial sealing element, wherein the tab at least partially covers the sealing element or the radial sealing element in a covering section in the radial direction.

In other words, the sealing element or the radial sealing element is preferably held perpendicular to its radial sealing effect by the tab, which serves as a kind of stop. Thus, in the case of a radial sealing element, the sealing surface, which preferably acts in the radial direction, is not influenced by the tab, since the holding effect takes place transversely to the direction of sealing. Falling out of the sealing element or the radial sealing element from the connector (housing) or slipping of the sealing element or the radial sealing element along the insertion direction, e.g. during transport or handling, is thus advantageously prevented without affecting the sealing effect or the active sealing surface.

Further advantageously prevents the tab, that the sealing element or the radial sealing element in a release of the connector from the mating connector in itself twisted or twisted or twisted and thus a sealing surface of the sealing element or the Radialdichtelements sections in a reversed direction - this remains the Sealing effect obtained even after a renewed mating connector and mating connector advantageous. When releasing the connector and the mating connector, e.g. Slightly slide the sealing element or radial sealing element along the insertion direction until it abuts the tab - there it is held and can then not twist.

Further advantageously, the assembly of the sealing element or the radial sealing element or the radial seal can be done easily and without damage. For the sealing element or the radial sealing element can e.g. be arranged on the connector before the shield plate is mounted with its at least one tab. Thus, there is no risk that the sealing element or the radial sealing element must be pushed over the edge of the tab during assembly and thereby possibly damaged, which could lead to a leak in the seal. In the same way, a disassembly of the seal can be done in a simple manner: either the shield element is removed before disassembly of the sealing element or the radial sealing element or the radial seal or the tab is bent in the insertion direction, so that the sealing element or the radial sealing element only over the smooth fold of the tab on the screen element must be pushed.

Finally, the proposed solution requires no further, separate element (for example a retaining plate or a fixing element) for the secure and permanent fixing of the sealing element or the radial sealing element. Rather, the holding function by an already provided in the connector element, namely the shield plate, effected by a tab of the shield plate protrudes laterally. This simplifies the assembly (no part can be forgotten) and makes the connector also cheaper. The tab is preferably designed so small that a shielding effect of the shielding plate is not affected. The tab can thus cause a corresponding opening in the shield plate in the projecting state.

The term "downstream" is used in the context of this application to indicate relative positions of elements to each other along an axis and is not intended to describe an electrical or fluidic current unless explicitly stated. The term "upstream" is used analogously.

The sealing element or the radial sealing element may be formed, for example, as a closed ring. It may, for example, comprise an elastic material, in particular for the most part. It may, for example, comprise an elastic plastic or rubber or rubber or Teflon or silicone or silicones, etc.
For example, in addition to the wall around which the sealing element or the radial sealing element runs, the connector additionally has an outer wall, wherein the wall serves as a kind of inner wall. For example, a cup-shaped cavity encircling the connector housing can be formed between the wall and the outer wall. This cavity can serve as a plug-in channel, for example. The radial sealing element can be arranged, for example only, on an outer surface of the wall and point from the outer surface of the wall with a sealing surface in this plug-in channel. In the plug-in channel can be plugged in the mating connector and mating connector, for example, a mating connector outer wall of a mating connector housing of the mating connector. The sealing effect then occurs, for example between an inner surface of the mating connector outer wall and the sealing surface. In other words, viewed from radially inward to outward results in the following sequence of elements: first the wall with its outer surface, it follows, for example, immediately and closely or tightly against the wall fitting the sealing element or the radial sealing element, which with its sealing surface after radially outward. Finally, in direct mechanical contact and sealingly with the sealing surface, the inner surface of the mating connector outer wall follows.

The connector may be an electrical connector or an optical connector or a mixed connector (optical and electrical). The contact element may be, for example, an electrical contact element for making electrical contact with a mating contact element of the mating connector. An electrical connector or an electrical contact element, for example, for the transmission of high currents, for example of at least 1A or at least 10A or at least 50A or at least 100A be designed suitable. In this case, voltages of at least 12V or at least 45V or at least 100V abut - an electrically conductive cross-section may thus be, for example, at least 1 mm ^2, or at least 10mm or at least 25mm ^{2. 2} Alternatively or additionally, such an electrical connector can be designed, for example, suitable for transmitting data streams with a high data rate of, for example, more than 100 Mbit / s or more than 1 Gbit / s or more than 10 Gbit / s.

The contact element may alternatively be an optical contact element, e.g. for optical coupling to an optical coupling element (optical counter-contact element) of the mating connector. In the latter case, the contact element may be e.g. be arranged on an optical waveguide.

The contact element may e.g. protrude along the insertion direction of the connector housing or protrude from a bottom of the connector housing along the insertion in the interior of the connector housing. The bottom is considered with respect to the insertion direction upstream of a contact point between the contact element and the mating contact element of the mating connector.

The shroud is designed to ensure the electromagnetic compatibility (EMC) of the connector, e.g. also in the interface to the mating connector. In this case, the penetration or the action of electromagnetic radiation from the outside of the connector or a connector assembly of connector and mating connector to the contact element should be reduced as possible or avoided altogether. Conversely, electromagnetic radiation emanating from the contact element or a line arranged thereon should not pass from the interior to the outside environment of the connector or the connector arrangement.

The shielding plate can preferably bring about a single core shielding or bring about a single contact element shielding. It is in such a case so each contact individually surrounded by a separate shield plate and thereby individually shielded.

The shroud may e.g. be mounted as initially separate element or component on or in the connector housing. The shielding plate can be mounted in such a way that on the one hand it is firmly and securely connected to the connector housing, e.g. by a non-positive or frictional connection. At the same time, however, it can be mounted in such a way that it can be dismantled from the connector housing without destruction and without much effort. For example, the shroud may be formed in the manner of a tube, e.g. is plugged into the connector housing opposite to the insertion direction. It can e.g. comprise one or more slots extending along the axial direction or a shield plate insertion direction. These slots may be e.g. be pushed over a corresponding projection or web in the connector housing and be attached in this way non-positively or frictionally engaged in the manner of a press fit or interference fit on the connector housing. To disassemble then the shield plate with a little effort to overcome the interference fit or interference fit simply pulled along the plug again from the connector housing and thus be removed. Basically, e.g. also a material connection with the connector housing possible or a screw or a bayonet lock.

The sealing element or the radial sealing element can circumnavigate an inner space of the connector or a plug connector arrangement in the assembled state of plug connector and mating plug connector and thus seal this inner space against fluid media from an outer environment of the plug connector or the plug connector arrangement. The contact element can be arranged, for example, in the interior, that is to say within the space circumscribed or surrounded by the radial sealing element. As a result, it is sealed against fluid media from the outside environment. This advantageously has the effect that the service life of the contact element increases, since there is no or only to a small extent harmful gases or Liquids is exposed and thus less prone to corrosion. Furthermore, for example, short circuits can be avoided if the contact element is an electrical contact element. In the case of optical contact elements, turbidity of the transition between contact element and mating contact element as a result of the action of fluid media can be avoided.

The interior can e.g. be cup-shaped enclosed by the connector housing. The outer wall can represent the cup wall, the bottom of the cup bottom.

The term "masking" is used in the context of the application in the sense of an overlap. In other words: an overlap in the radial direction corresponds to a shadow of the overlapping element (here: the tab) from the axial direction (opposite to the insertion) on the covered element (here: the sealing element or the radial sealing element). The shadow may be viewed along the radial direction, e.g. cover only a part of a width of the radial sealing element, e.g. at least 5% or at least 10% or at least 15% and e.g. at most 90%. However, it can also cover the entire width of the sealing element or the radial sealing element. Advantageously, the tab does not project beyond the sealing element completely in the radial direction, so as not to be in the way when mating connectors and mating connectors in this way. Viewed along the direction of rotation, the tab does not have to completely cover the sealing element or the radial sealing element; Cover only a small part of the sealing element or the radial sealing element.

The fact that the tab covers the radial sealing element in the covering section in the radial direction in such a way that the radial sealing element is secured against displacement along the insertion direction advantageously prevents unintentional falling out or slipping or twisting of the sealing element or of the radial sealing element.

The holding action of the tab can occur at the latest when the radial sealing element comes into mechanical contact with the tab.

The fact that the tab covers the sealing element or the radial sealing element at least 1% and at most 98%, preferably at least 15% and at most 98%, of a width of the sealing element or of the radial sealing element, along the radial direction from within the sealing element or considered radially outside of the sealing element or the radial sealing element, is advantageously effected that on the one hand, the tab far enough over the sealing element or radial sealing element to unfold with respect to the sealing element or the radial sealing element a holding action along the insertion direction. At the same time, it is advantageously effected that when the plug-in connector and mating plug-in connector are plugged together, the tab does not block the plug-in procedure - in other words, the tab does not collide with the mating plug-in connector.

Alternatively it can be provided that the tab covers the sealing element or the radial sealing element to at least 20% and at most 90% of its width. As a result, an even better holding effect is advantageously effected and the risk of a collision with the mating connector is further reduced. In addition, tolerances in the width of the sealing element or the radial sealing element can be better intercepted in this way without the function of the sealing element or the radial sealing element is impaired by the tab.

Alternatively, it can be provided that the tab covers the sealing element or the radial sealing element to at least 25% and at most 80% of its width. As a result, an even better holding effect is advantageously effected and the risk of a collision with the mating connector is further reduced. In addition, tolerances in the width of the sealing element or the radial sealing element can be better intercepted in this way without the function of the sealing element or the radial sealing element is impaired by the tab.

The fact that the shield plate is detachably arranged on or in the connector housing advantageously causes a particularly simple and damage-free assembly and disassembly of the sealing element or of the radial sealing element. For so the sealing element or the radial sealing element does not have to be slipped over the tab - but the shield plate can be mounted after assembly of the sealing element or the radial sealing element and dismantled before disassembly of the sealing element or the radial sealing element.

Alternatively it can be provided that the shielding plate is inserted into the connector housing. This allows a particularly simple assembly and disassembly of the shielding plate in the connector housing. Such a connector may e.g. stable position by the shield plate as shown above, e.g. is releasably secured by a press fit or a clamping fit on or in the connector housing (non-destructive).

By virtue of the fact that the shielding plate has a plurality of tabs which are arranged along the insertion direction downstream of the sealing element or the radial sealing element and at least partially cover the sealing element or the radial sealing element in each case in a covering section in the radial direction, the holding effect with respect to the sealing element or of the radial sealing element. A plurality in the context of the application at least two elements to understand. Thus, the shroud, for example, two, three, four or more tabs, which protrude laterally outwardly from the shield plate. Not every tab has to cover the sealing element. In this way, for example, the mounting of the shielding plate can be simplified: for example, four tabs are arranged on the shield plate at an equidistant distance along the direction of rotation, the shield plate can be mounted in four different orientations and it is nevertheless ensured that at least one or at least two of the tabs at least partially cover the sealing element or the radial sealing element. With an even higher number of tabs, the assembly is correspondingly simplified and at the same time the holding functionality with respect to the sealing element or the radial sealing element ensured. For example, five, six, eight, ten, twelve or 18 tabs may be provided, preferably in equidistant spacing along the direction of rotation. Preferably located between adjacent tabs depending on a piece of shroud, which is not designed as a tab.

Characterized in that the connector has a plurality of contact elements, which are arranged on or in the connector housing, wherein the sealing element or the radial sealing element rotates the plurality of contact elements is advantageously ensured that all contact elements are arranged within the sealed space.

Characterized in that the connector has a plurality of shield plates, each surrounding a contact element, projecting from at least one of the shield plates a tab along the radial direction, wherein the tab along the insertion direction downstream of the sealing element or the radial sealing element is arranged, wherein the Lasche the sealing element or the radial sealing element in a cover portion in the radial direction at least partially covered is advantageously causes the shield is formed in the form of a single wire shield or Einzelkontaktelementschirmung and at the same time the holding effect is ensured with respect to the sealing element or the radial sealing element. Through the single core shield can be prevented that electromagnetic radiation of a contact element or a line acts on another contact element or on another line in the same connector.

It is understood that either exactly one of the shield plates can have exactly one tab or a plurality of tabs with a holding function. It is also conceivable that a plurality, but not all, of the shrouds may comprise one or more tabs (e.g., two, three, four or more tabs), which may comprise exactly one tab (s), e.g. at least partially project beyond the sealing element or the radial sealing element or overlap or overlap. However, as shown above, there may also be individual tabs which do not protrude beyond the sealing element or the radial sealing element or project beyond it only when the associated shielding plate is oriented correctly (along the direction of rotation). Finally, it is also conceivable that all the shrouds have exactly one or more (for example two, three, four or more) tabs, these being exactly one tab or the several tabs e.g. at least partially project beyond the sealing element or the radial sealing element or overlap or overlap.

In a further development, the connector has a secondary locking element which can be arranged in particular releasably on or in the connector, wherein the secondary locking element in the radial direction in the connector housing is inserted and engages in an inserted state, an undercut of the contact element, so that the contact element not against Plug-in direction can be removed from the connector. The secondary locking element is arranged downstream of the sealing element or the radial sealing element in the inserted state along the insertion direction, the secondary locking element at least partially covering the sealing element or the radial sealing element in a further covering section or in a plurality of further covering sections in the radial direction. This advantageously has the effect that the sealing element or the radial sealing element is secured even more reliably and reliably against slipping or twisting or falling out. If a secondary locking element is provided anyway to secure the contact elements, this now fulfills two functions, similar to the shield plate: the secondary locking of the contact elements and the holding function with respect to the sealing element or the radial sealing element. A further element (for example a retaining plate or a fixing element) for securing the sealing element or the radial sealing element can thus advantageously be dispensed with.

At the same time, the sealing element or the radial sealing element in this way special easy to install and disassemble without damage: it does not have to be put over any protrusions with the risk of being damaged. Rather, the sealing element or the radial sealing element is first mounted, then the secondary locking element is mounted while the sealing element or the radial sealing element secured or held (before or after the shield plate can be mounted). For disassembly, the secondary locking element is first removed from the connector housing, for example by pulling or pushing out of the connector housing. Subsequently, (although the shield plates have been dismantled), the sealing element or the radial sealing element without damage and are easily removed from the connector.

Particularly advantageously, the secondary locking element is designed such that it does not protrude beyond the width of the sealing element or of the radial sealing element in the plugged into the connector housing or inserted state from radially inside, so as not to be in the way when plug connector and mating connector mating ,

The term "secondary locking element" implies the presence of a primary lock. This can e.g. caused by the latching of a locking lance of the contact element on an undercut of the connector housing or by latching a latching arm of the connector housing in an opening or behind an undercut of the contact element. However, it is also possible in principle that the locking or securing of the contact element or of the contact elements in the connector housing takes place exclusively by the secondary locking element. In this case, a Primärverrastung or primary locking and thus eliminates the secondary locking element could simply be referred to as a "locking element". However, in the context of this application, the term "secondary locking element" is always used for reasons of better readability.

By way of example only, the secondary locking element may comprise a base member from which at least two arms protrude, e.g. each arm is formed at its distal end as a free end. The arms may be spaced apart from each other and e.g. parallel to each other. Base member and arms may e.g. be formed comb-like, wherein the base member represent the comb back and the arms the comb teeth.

In principle, the secondary locking element can either be arranged along the insertion direction downstream or upstream of the tab or the tabs of the shielding plate or the shielding plates.

As a result of the fact that the radial sealing element along the insertion direction is covered downstream along at most 30% of an extension length of the sealing element or the radial sealing element or along at most 20% of its extension length or along at most 10% of its extension length, the sealing element or the radial sealing element along advantageously the circulation direction is always sufficiently flexible, even if it comes into mechanical contact with the tab or tabs or the secondary locking element. Because the sealing element or the radial sealing element is always covered only selectively or partially and not completely, which allows the uncovered sections greater flexibility or mobility in the direction of rotation and axial direction in this way. This can e.g. be advantageous for large temperature differences with corresponding changes in length.

According to a second aspect of the invention, a method for producing a connector for mating with a mating connector in a plug-in direction is proposed.

The method comprises the following steps:

• - Providing a connector housing;
• - Providing a contact element;
• - Providing a sealing element, preferably a radial sealing element;
• - Providing a shield plate, wherein protrudes from the shield plate, a tab along a radial direction perpendicular to the insertion direction;
• - mounting the contact element in the connector housing;
• - mounting the sealing element or the radial sealing element on a wall of the connector housing, so that the sealing element or the radial sealing element rotates the wall in a circumferential direction about the insertion direction;
• - Mounting the shield plate in or on the connector housing, so that the shield plate rotates the contact element and that the tab viewed along the insertion direction, the sealing element or the radial sealing element downstream in a covering portion in the radial direction at least partially covered.

This can be particularly simple, damage-free and without additional parts, the sealing element or the radial sealing element on Be secured connector. Disassembly of the sealing element or the radial sealing element can also be done damage-free and easy by the steps are performed, for example, in the reverse order. As a result, the sealing element or the radial sealing element can be removed from the connector, for example, for inspection purposes, without having to be slipped over a retaining collar or retaining edge and thereby exposed to the risk of damage.

• -- Bereitstellen eines Sekundärverriegelungselements;
• -- nach den Schritten des Montierens des Kontaktelements und des Radialdichtelements :

  • wobei das Sekundärverriegelungselement das Radialdichtelement in einem weiteren Überdeckungsabschnitt oder in einer Mehrzahl von weiteren Überdeckungsabschnitten in radialer Richtung zumindest teilweise überdeckt bzw. überlappt bzw. überragt.

A further development provides that the method further comprises the following steps:

• - Providing a secondary locking element;

  • wherein the secondary locking element at least partially covers or overlaps the radial sealing element in a further overlapping section or in a plurality of further overlapping sections in the radial direction.

As a result, an additional securing of the sealing element or of the radial sealing element is effected. The secondary locking element then fulfills - analogous to the shielding plate - with the holding function another function in addition to its main function and makes a separate holding element superfluous. In addition, a simple and damage-free assembly and disassembly of the sealing element or the radial sealing element is also possible by the secondary locking element, without affecting the holding effect or securing effect of the secondary locking element with respect to the sealing element or the radial sealing element.
