Description

The invention relates to a connector device with at least one connector, the connector having a housing, at least one connector body for connection to an outer conductor of a cable and at least one inner conductor part for connection to an inner conductor of the cable, according to the preamble of claim 1.

When assembling cables, their conductors are typically connected with a connector. The connector can be a plug, a socket or an adapter. The term connector used in the context of the invention is representative of all variants.

The connector is used to establish an electrical connection with a correspondingly complementary further connector.

To connect the cable to the plug connector, a plug body is generally provided which is connected to an outer conductor of the cable. Furthermore, the plug connector has at least one inner conductor part which is provided for connection to an inner conductor of the cable. The number of inner conductors or inner conductor parts is not restricted in the present case, with common connectors, in particular HF connectors or connectors for coaxial cables, mostly having only one inner conductor part for connection to an inner conductor of the cable.

The known connectors have a housing, preferably a plastic housing, with a receptacle for inserting the at least one plug body.

The connection of the plug body to the outer conductor of the cable or of the at least one inner conductor part to an inner conductor of the cable can take place with known measures, usually by means of soldering, gluing, clamping or crimping.

A connection between the cable and the plug connector can be established by stripping a section of the cable sheath in a first step. This exposes an outer conductor. The outer conductor can be, for example, a braided cable shield. A support sleeve is then crimped onto the braided cable shield in such a way that the braided cable shield protrudes beyond the support sleeve. The protruding cable shield braid can be folded back in a next step and placed over the support sleeve. The front end of the cable can then be stripped further so that an inner conductor of the cable is exposed. The exposed inner conductor of the cable can then be connected to the inner conductor part of the plug connector, preferably in such a way that the inner conductor part is crimped on. Then the stripped front end of the cable is inserted into the connector body. The connector is preferably put back on the outer conductor of the cable or the cable shielding braid, which is preferably pulled back over the support sleeve is crimped on. Thus, the plug body is reliably connected to the outer conductor of the cable by crimping and the inner conductor part is protected within the plug body.

It is then provided that the cable sheath of the cable is stripped preferably 10 to 15 mm behind the connector and a metal clamp is crimped directly onto the cable shielding braid of the cable. The metal clamp is used to establish a reliable or low-resistance ground connection, for example with the body of a vehicle, which is in electrical connection with a negative pole of a battery when the plug is used in a vehicle.

Attaching the metal clamp directly to the braided shield of the cable has the disadvantage that the cable sheath is additionally damaged so that contacting of the braided cable shield is possible at all.

The present invention is not restricted to use in a vehicle, the term vehicle including any means of locomotion within the scope of the invention, in particular vehicles on land, on water or in the air, including spacecraft.

The invention is not restricted to a specific plug connection device or a specific plug connector, the invention being particularly suitable for assembling HF cables. The connector can preferably be used as an HF connector, in particular PL connector, BNC connector, TNC connector, SMBA (FAKRA) connector, N connector, 7-16 connector, SMA connector, SMB connector, SMS Connector, SMC connector or SMP connector can be designed.

The connector can be designed as a so-called FAKRA connector, which corresponds to the so-called FAKRA standardization scheme (FAKRA = specialist group automotive technology) for SMB connections. In this case, a plastic housing is provided which holds the plug body, protects it and pre-positions it for the plugging process with another connector with a plastic housing. The housing can also have mechanical coding so that only matching housings can be plugged into one another.

From the US 2003/0176104 A1 a coaxial connector with a plastic housing is known which corresponds to the so-called FAKRA standardization scheme for SMB connections.

Such plastic housings for coaxial connectors, which are also called FAKRA housings, are used in automotive engineering for data transmission cables. These data transmission cables are usually coaxial cables or similar shielded cables based on a single electrical conductor. The mechanical dimensions of such FAKRA housings in the interface area, ie in an axial section of the housing which interacts with a complementary connector to establish a mechanical connection between the two plastic housings, are in DIN 72594-1 in the version of October 2004 set.

The invention is particularly suitable for such plug connectors.

When inserting the plug body into the housing, for example a FAKRA housing, it is essential that the connection dimensions are correctly adhered to, so that a complementary connector can be connected to the connector without damage and also the signal transmission is optimal.

It is known from the prior art to insert a fuse element, which is referred to as a secondary fuse in the prior art, into the housing in order to fix the plugged-in connector body in the end position. The secondary fuse is inserted into the housing orthogonally to the direction of insertion of the plug body.

The known connectors, in particular also the connectors according to the FAKRA standardization scheme, enable a secure and reliable connection with a complementary connector. One disadvantage, however, is that in order to establish a ground connection, the cable jacket must also be damaged in order to contact the outer conductor, in particular the braided shield of the cable. The contacting of the braided shield and the stripping of the cable sheath also require a corresponding effort during assembly and endanger the functional reliability.

The present invention is based on the object of simplifying the assembly of a plug connection device and improving the functional reliability.

This object is achieved according to the invention by claim 1.

Advantageous embodiments of the invention are described in the further claims.

The connector device according to the invention has at least one connector. The plug connector has a housing, at least one connector body for connection to an outer conductor of a cable and at least one inner conductor part for connection to an inner conductor of the cable.

The plug body preferably has means for connection to the outer conductor and the inner conductor part preferably has means for connection to the inner conductor of the cable.

Each plug connector preferably has only one plug body, but it is also possible to assign several plug bodies to a plug connector.

Depending on the design of the plug connector, it can have one or more inner conductor parts for connection to one or more inner conductor parts of the cable.

For a preferred embodiment of the connector, in particular also as a FAKRA connector, the formation of precisely one inner conductor part for connection to an inner conductor of the cable is particularly suitable. Such a configuration is also particularly suitable if the plug connector is intended for connection to a coaxial cable.

In the context of the invention, the feature “plug body” can include both a plug body and a plurality of plug bodies which are each assigned to a plug connector. Furthermore, the feature “inner conductor part” can define only one inner conductor part or also several inner conductor parts which are connected to a corresponding number of inner conductors of a cable and are jointly assigned to a connector.

According to the invention it is provided that the housing has at least one receptacle for inserting the at least one plug body. The housing can in principle be designed in such a way that it has a plurality of receptacles for inserting a plurality of plug bodies. In a particularly preferred embodiment, in particular if the housing is a so-called FAKRA housing, only one receptacle for inserting a plug body is provided. However, the invention is not limited to this.

According to the invention, a contact element is provided which can be inserted into the housing in such a way that a front region of the contact element makes electrical contact with the plug body inserted into the housing on its outer circumference, the contact element being electrically conductively connected to a fastening means to establish a ground connection independently of the cable with another component.

This solution facilitates the assembly of the connector device and increases the functional reliability.

The solution according to the invention enables a connection between the outer conductor of a cable and a ground connection in a particularly simple manner. For this purpose, the contact element makes contact with the plug body inserted into the housing, which according to the invention is connected to an outer conductor of a cable, and thereby establishes an electrical connection with the fastening means. For this connection it is no longer necessary for the cable sheath to be stripped outside the housing and an earth terminal to be crimped onto the braided shield of the cable. The solution according to the invention makes it possible to establish the connection within the housing without an additional stripping process being necessary.

The solution according to the invention enables an outer conductor of a cable to be connected to a plug body. The plug body can have a connection area in order to connect a further plug, a cable or the like to the plug body. In addition, it is now provided according to the invention that a contact element makes electrical contact with the plug body on its outer circumference, around an additional connection, which is a ground connection, with another component. The further component can be a mass part, for example a vehicle mass (body, negative battery pole or the like).

The connector according to the invention can be provided for connecting the cable to a complementary or matching connector at a connection area of the connector, for example to connect the cable to a continuing cable or to connect the cable to a circuit board or an electrical device. In addition, the outer conductor of the cable is connected to the further component via the contact element, which makes electrical contact with the outer circumference of the plug body, and the fastening means, in order to create an additional ground connection.

The outer conductor of the cable can thus advantageously be electrically connected to the further component via the contact element or the fastening means. The electrical signal transmission quality can be improved by the ground connection. In particular, improved shielding can be ensured and the electrical connection can be more robust overall.

Because the contact element can be plugged into the housing of the plug connector and is designed to establish the ground connection with the further component, a secondary fuse can be combined with a ground connection. The secondary fuse can be designed to show a fitter the correct positioning of the plug body relative to the plug connector and / or the housing of the plug connector, the secondary fuse preferably only being insertable if it is correctly positioned. This can preferably be ensured by the fact that a displacement path for inserting the contact element is only fully accessible when the parts of the plug connector are correspondingly aligned with one another or inserted into one another.

The fastening means can be designed as desired. The fastening means can in particular be designed to produce a simple ground connection, for example to the body of a vehicle or another suitable component. The fastening means can be connected to a vehicle ground, for example, by a screw connection or similar measures.

It is sufficient if the fastening means is designed to produce a simple ground connection. It is not necessary for the fastening means itself to be fastened directly to the further component, for example the body of a vehicle. It can be sufficient if the fastening means serves to establish an electrical connection between the contact element and the further component without itself being mechanically fastened to the further component.

If the connector is to be mechanically fastened, this can optionally be done using additional holders. In one embodiment of the invention, however, it can be provided that the fastening means itself is already designed in such a way that the fastening means can be mechanically fixed or fixed directly or via fixing elements. The fixing or fastening can take place on the further component with which the ground connection is also established. However, the invention is not restricted to this. It can also be provided that the definition of the connector via the fastening means on any, possibly also non-conductive, component.

The connector device according to the invention is suitable for any connector, in particular the connector already mentioned, and can preferably be used with all HSD, FAKRA and high-voltage connectors that have a metallic, in particular shielding, outer conductor.

It is advantageous if the front area of the contact element can be positively connected to at least part of the outer circumference of the plug body.

A positive connection ensures good and reliable electrical contact. Furthermore, a form-fitting connection also fulfills the task of secondary securing of the plug body in the housing, whereby the connection dimension can also be ensured.

According to the invention it can be provided that the contact element is inserted into the housing at an angle, preferably orthogonally to the longitudinal or axial axis of the plug body, and is positively connected to the plug body in an orthogonal orientation. This creates a particularly suitable secondary fuse.

The connection of the plug body to the housing can in principle be made in any way. However, it is particularly advantageous if the plug body is inserted into the receptacle of the housing in the axial direction of the plug body. For this purpose, the receptacle can preferably be designed as a bore, in particular as an axial bore, in the housing. With this type of connection of the plug body to the housing, a particularly advantageous secondary fuse can subsequently be established by the contact element, which ensures with little effort that the plug body is no longer accidentally or independently detached from the housing and, in particular, the connection dimension is defined.

The housing is preferably made of plastic.

It is advantageous if the plug body and the receptacle are designed such that an end position of the plug body is defined in the receptacle of the housing.

Such a design of the plug body and the receptacle enables the plug body to be positioned in the housing before the contact element is inserted into the housing and preferably provides a secondary fuse.

The housing is preferably designed in such a way that the plug body is locked in the intended end position, for which purpose, for example, a snap connection, in particular a snap body or a snap hook, is used, which enables the plug body to be pushed in, but prevents it from being withdrawn against the insertion direction.

The housing or its receptacle is preferably designed such that it serves as a primary fuse for the plug body. The primary fuse is preferably designed to be detachable. The housing is preferably designed as a FAKRA housing, which can already have such a primary fuse.

It is advantageous if the plug connector has a securing element which can be introduced into a recess in the housing in such a way that a movement of the housing with respect to the securing element is limited at least in one degree of freedom.

The securing element, just like preferably the contact element, can serve as a secondary securing device which secures the plug body in the housing or the receptacle of the housing as soon as it has reached the intended end position.

The securing element is preferably fed to the plug body at an angle, particularly preferably orthogonally to its axial direction, which results in a particularly advantageous securing.

It is advantageous if at least part of the securing element is located in a displacement path of the plug body introduced into the housing.

In particular, when the plug body is pushed into a receptacle in the housing by moving along its axial axis, it is particularly suitable to design the securing element and insert it into the housing in such a way that part of the securing element is in a displacement path of the plug body inserted into the housing. This can be achieved particularly advantageously if the plug body has a taper, a recess, an indentation or an indentation into which at least a part of the securing element can penetrate in order to prevent the plug body from being pulled out again and / or pushed back into the receptacle.

Alternatively, but less suitably, the plug body can also have a projection or a bulge that is blocked by a part of the securing element.

The securing element can have a latching hook or the like which hooks onto a correspondingly suitable recess of the housing so that the securing element is prevented from being pulled out again when it is pushed in so far that the securing element secures or fixes the plug body. Alternatively, the housing can also have a latching hook and the securing element can be designed accordingly. The receptacle or the housing can be designed in such a way that the latching hook can be released again in order to remove the securing element again if necessary and to pull the plug body out of the housing again, if necessary after additionally releasing the primary fuse.

In a particularly advantageous embodiment, the contact element, together with the securing element, serves as a secondary safeguard in order to fix and secure the plug body in the end position in the receptacle.

It is particularly advantageous for securing the plug body if it has a taper on its outer circumference into which the contact element and preferably also the securing element or part of the securing element engages. The taper can be designed as an annular circumferential taper.

Depending on the design of the plug body, it can be provided that it has a two-part or multi-part structure. In this case it can be provided that a taper is formed at the connection point of two parts of the plug body, which is used for the engagement of the contact element and / or the securing element.

To produce a particularly suitable connection between the contact element and the plug body, at least the front region of the contact element can be designed as a clamp. The clamp can preferably have two clamp arms which at least partially enclose the plug body on its outer circumference. The clamp can be designed in such a way that it has two partially annular clamp arms and the clamp is pushed onto the outer circumference of the plug body laterally or from a radial direction. The clamp is preferably designed in such a way that it clamps at least part of the outer circumference of the plug body between it and thereby fixes it. The terminal preferably comprises an annular section of more than 180 ° of the outer circumference of the plug body.

Regardless of the specific design of the contact element, but in particular when the contact element is designed in such a way that the front area is designed as a terminal, it can be provided that the contact element is detachably connected to the plug body.

It is advantageous if the securing element is positively connected to the contact element.

For this purpose it can be provided in particular that the securing element has a recess and the contact element is designed as a clamp at least in the front area. The clamp can protrude through the recess, the contact element being prestressed in such a way that the contact element spreads open in the recess and is thus connected to the recess in a form-fitting manner. It is particularly advantageous if the contact element has a recess or a recess which is positioned in the region of the recess so that the edge of the recess of the securing element engages in the recess of the contact element and thus a positive fit is established.

Instead of a recess, the clamp can also have a projection and the recess can be designed in a correspondingly complementary manner.

After their positive connection, the contact element and the securing element can be handled as one component. In this embodiment, it may be appropriate to establish the electrically conductive connection between the contact element and the fastening means via the securing element. In this case, the securing element is at least partially made of metal, preferably completely made of metal.

The contact element or the securing element can be connected to the fastening means, in particular be connected in an electrically conductive manner.

It can be provided in one embodiment that the contact element is located in a recess of the fastening means without contacting the fastening means. In this embodiment it can be provided that the securing element is connected to the fastening means in an electrically conductive manner, at least when the contact element and the securing element are inserted into the housing in the intended manner and the contact element makes electrical contact with the plug body. In this embodiment, the fuse element is at least partially electrically conductive, preferably by being at least partially or completely made of metal. The connection between the securing element and the fastening means can in this case take place in that the securing element is connected to the fastening means, for example by a snap connection or in some other way. In one embodiment of the invention, however, it is also possible that only the housing of the plug connector is connected to the fastening means, for example likewise by a snap connection or otherwise, and the securing element is located between the housing and the fastening means. The fastening means can, for example, have a plate-shaped profile in the contact area with the securing element, so that the securing element is clamped between the housing and the fastening means, in particular electrically conductively connected to the fastening means, after the connector or its housing has been fastened to the fastening means. The electrically conductive, preferably form-fitting connection between the securing element and the contact element and, since the contact element makes electrical contact with the plug body, an electrically conductive connection is thus established between the plug body via the terminal or the contact element and the securing element with the fastening means.

Such a configuration is particularly easy to implement and only requires simple assembly steps.

According to the invention it can also be provided that the contact element is inserted positively into a recess of the fastening means or is formed in one piece with the fastening means.

In particular, as an alternative to producing an electrically conductive connection between the contact element and the fastening element by means of the securing element, it can also be provided that the contact element is connected directly to the fastening means, in particular such that an electrically conductive connection is made. For this purpose, the fastening element can have a recess into which the contact element is inserted in the same way as this has already been described with regard to a possible connection of the contact element with a recess in the securing element. As a result, a form-fitting and possibly releasable connection is established between the fastening means and the contact element. The connection can be established quickly and reliably with simple measures. Alternatively, it can also be provided that the contact element is connected to the fastening means in some other way, for example by soldering, gluing, riveting or the like. It can also be provided that the contact element is formed in one piece with the fastening means. In particular, if the contact element is formed in one piece with the fastening element, the securing element can optionally be omitted.

In particular if the contact element is connected to the fastening means in an electrically conductive manner, a metallic design of the securing element can be dispensed with. In this embodiment it is advisable to make the securing element from plastic. Furthermore, in this embodiment it is advisable for the securing element to have a passage in order to insert the contact element and to connect its front area to the plug body.

In this embodiment, it can be provided that the fuse element is first inserted into the housing, for example preassembled. Before or afterwards, the connector housing can be pushed into the receptacle of the housing up to the intended end position. The securing element can then preferably be pushed in further in the manner already described until it secures the position of the plug body in the receptacle and preferably serves as a secondary safeguard. The contact element can then be inserted at any point in the housing; the contact element is preferably inserted into a passage in the securing element in such a way that the contact element is pushed in until its front area is connected to the plug body.

It is advisable that the contact element is connected to the fastening means beforehand, preferably in a form-fitting manner, and the connection to the housing takes place in that the housing is clipped onto the contact element and thus preferably the housing is attached to the fastening means on the one hand and the plug body on the other the contact element, which is preferably designed as a clamp in the front area, is clipped on.

Of course, the connection of the fuse element and the contact element to the housing can also take place in a different order.

The fastening means is preferably formed at least partially from metal or an electrically conductive material. The fastening means is preferably made of metal.

The contact element is formed at least partially from an electrically conductive material, preferably at least partially from metal, particularly preferably completely from metal. The contact element is preferably designed entirely in the form of a clamp, which preferably has resilient properties in order to reliably encompass the plug body on its outer circumference.

It is advantageous if the fastening means has at least one support and / or at least one snap connection part for fastening the housing of the plug connector. It when the fastening means has both a support and a snap connection part is particularly advantageous.

The snap connection part can for example be designed as a snap hook which snaps into a suitable counter element of the housing and fixes the housing in the intended position on the fastening means. Alternatively, the housing can also have one or more snap hooks that engage a suitable counterpart of the fastening means. The support of the fastening means can be designed, for example, as a plate-shaped projection, optionally with a suitable edge projection for a defined reception, in particular for placing an underside of the connector.

In a development of the invention it can be provided that the at least one snap connection part penetrates at least partially into a groove in the outside of the housing in order to form a positive connection in the axial direction (or insertion direction) between the housing and the fastening means.

Preferably, two snap connection parts are provided in the manner of snap hooks. The snap hooks can at least partially, preferably completely, encompass the housing of the plug connector on two opposite outer sides. The snap hooks can be designed in such a way that they can be pushed laterally over the outer circumference of the housing of the connector. The snap hooks preferably clamp part of the outer circumference of the housing of the plug connector between them and thereby fix the fastening means (releasably) on the housing.

The fastening means can have at least one eyelet. The eyelet can be provided in order to establish a connection between the fastening means and a mass part, for example a vehicle mass. For this purpose, for example, a screw can be inserted through the eyelet and the fastening means screwed accordingly. Other connection options are also conceivable here, in particular detachable connections such that the fastening means can again be easily detached from the mass part. A low-resistance electrical ground connection is preferably established.

In a further development of the invention, it can in particular be provided that the fastening means has connecting elements in order to establish or form the ground connection with the further component. A connecting element can also be the aforementioned eyelet.

In one embodiment, the fastening means can also be formed or consist only of the connecting elements or a connecting element.

The fastening element can preferably be designed in such a way that it has connecting elements in order to establish a ground connection with the further component or to enable the connection. Particularly preferably, the fastening means can be designed in such a way that it has a design to fasten the fastening means to the housing, in particular such that the fastening means is fixed to the housing in a defined manner and, in particular in connection with the fixing of the contact element, has a precise positioning of the fastening means on the housing results.

The fastening means can also be designed in such a way that it has means for fixing the fastening means mechanically to a further component, for example also the further component. But this is optional. A mechanical fixing of the fastening means on a further component is not primarily important. This can also be achieved in other ways within the scope of the invention, if a fixing of the fastening means to a further component is provided at all. In the context of the invention, it is essential that the contact element is electrically conductively connected to the fastening means, and the fastening means is designed to produce an electrically conductive connection between the contact element and a further component, the connection being designed as a ground connection.

In a particularly preferred development, the connecting elements can be designed as a crimp connection in order to connect a ground connection cable to the fastening means. As a result, the ground connection with the further component can be established or formed in a simple manner.

The use of a ground connection cable as an electrical connection between the fastening means and the further component has proven to be particularly flexible in handling. The ground connection cable can be connected to a connection area of the fastening means in an electrically and mechanically robust manner via the crimp connection, for example via one, two or more crimp terminals. To connect to the further component or a ground part, the ground connection cable can be attached to the end that is not connected to the fastening means, e.g. B. have an eyelet, a cable lug or the like, which, for example, is crimped onto the ground connection cable. The ground connection cable can then, for example, be screwed to the further component or plugged onto a connection point of the further component.

The ground connection cable can also be connected to the further component or the ground part in some other way, for example by gluing, soldering or clamping. The connection of the ground connection cable to the fastening means can also take place in other ways, for example the connection elements can be designed as soldered connections, adhesive surfaces and / or clamping surfaces.

In a preferred development, it can be provided in particular that the fastening means, the at least one snap connection part, the contact element and the connection elements for the ground connection are designed in one piece.

The fastening means is preferably designed as a one-piece sheet metal with the aforementioned components. The fastening means can then preferably be manufactured using the punching and bending technique.

In a development it can be provided that the housing of the plug connector and the fastening means are designed in such a way that the fastening means, when this is inserted into the housing of the plug connector, does not protrude beyond the outside of the housing of the plug connector.

In particular, if the fastening means is designed as a sheet metal, it can extend tightly along the outer circumference of the housing of the connector (preferably coplanar with the assigned outer sides of the housing or set back with respect to the assigned outer sides of the housing). The connector can thus have a compact structure and the fastening means can be protected from damage.

It is advantageous if the fastening means is designed for fastening and making electrical contact with a plurality of plug connectors.

The electrical contact can be made via the contact elements, which can be part of the fastening means or can be connected to it, in the manner already described.

The plug-in connectors can preferably be inserted into the fastening means or connected to it parallel to one another.

In one embodiment of the fastening means for receiving a plurality of plug connectors, it can be advantageous if two or more connection options, in particular eyelets, are available for fastening a fastening means to a mass part, for example a vehicle mass.

The contact element according to the invention, in particular in combination with the fuse element, can advantageously take on the task of secondary fuse or generally fuse and thereby also ensure the connection dimension, and also establish a connection between the outer conductor of the cable and a ground part. If the plug connection device according to the invention is used in a vehicle, the mass part can be a vehicle mass, in particular to establish an indirect electrical connection to a negative pole of a vehicle battery.

The connector according to the invention can in particular be provided for connection to a data transmission cable, in particular for high-frequency applications.

In the following, exemplary embodiments of the invention are shown in principle with reference to the drawing.

The figures each show preferred exemplary embodiments in which individual features of the present invention are shown in combination with one another. The features of an exemplary embodiment can also be implemented separately from the other features of the same exemplary embodiment and can accordingly be combined by a person skilled in the art to form further meaningful combinations with features of other exemplary embodiments.

In these figures, the fastening means 2 is also designed in such a way that the fastening means can be mechanically fixed to a further component / component. The Figures 12 to 14 show a particularly preferred variant of the invention, according to which the fastening means 2 is formed in one piece with the contact element 13. In the Figures 12 to 14 no means are formed on the fastening means 2 in order to mechanically fix the fastening means 2 mechanically to another (arbitrary) component. In principle, however, this is also possible. In the Figures 12 to 14 although a one-piece design of the fastening means 2 with the contact element 13 is shown, this is not mandatory. The fastening means 2 and the contact element 13 can also be designed as independent elements and only electrically and preferably also mechanically connected to one another.

Figure 1 shows a vertical longitudinal section through the plug connection device according to the invention with a plug connector 1 and a fastening means 2.

The connector 1 has a housing 3, which is also in the Figures 2 to 4 and 8 to 11 is shown in more detail. This can be a so-called FAKRA housing of a connector 1.

The Figures 13 and 14 show a variant of the housing 3 which differs somewhat from this, but which is preferably also designed to be compatible with the FAKRA standardization scheme.

The housing 3 is preferably made of plastic.

The connector 1 also has a connector body 4, which is connected to an outer conductor 5 of an in Figure 1 only schematically shown cable 6 is connected. The connector body 4 can be connected to the outer conductor 5 using known measures, for example by soldering, gluing, clamping or crimping. In the exemplary embodiment, it is provided in a manner not shown in the drawing that the plug body 4 is crimped to the outer conductor 5. For this purpose, the plug body 4 can optionally also be constructed in several parts, preferably at least a part of the plug body 4 is constructed in order to be crimped onto the outer conductor 5. This can preferably take place in that a cable sheath 7 of the cable 6 is stripped to such an extent that the outer conductor 5, which can preferably be a braided shield, is exposed. The plug body 4 can then be crimped onto this braided shield. If necessary, it can be provided for this that first a support sleeve (not shown) is crimped onto the outer conductor 5, in particular the braided shield, and the braided shield is then folded back over the support sleeve and only then a part of the plug body 4 or a connecting piece for connection to the plug body 4 or the connector body 4 is crimped in one piece onto the folded outer conductor 5 or otherwise connected to it.

The connector 1 also has at least one inner conductor part 8 (see Figure 4 ), which is provided for connection to an inner conductor 9 of the cable 6. The connection can be made, for example, by soldering, gluing, clamping or crimping. In the exemplary embodiment it is provided that the inner conductor part 8 is crimped onto the inner conductor 9 of the cable 6. The inner conductor part 8 is preferably connected to the inner conductor 9 of the cable 6 after the outer conductor 5 of the cable 6 has been exposed and preferably turned over, and before the plug body 4 is crimped onto the outer conductor 5. To fasten the inner conductor part 8 on the inner conductor 9, the latter can be stripped beforehand, which can be done with known measures.

The Figure 4 shows in section and by way of example the course and the arrangement of the inner conductor part 8 within the plug body 4. In a synopsis with FIG Figure 1 it is shown here how the connector 1 provides a connection in order to put on a further complementary connector (not shown) and to connect it electrically to the inner conductor part 8 and the connector body 4.

The one in the Figures 13 and 14 The connector 1 shown, the connection to the outer conductor 5 of the cable 6 (not shown there) and the connection of the inner conductor 8 of the cable 6 to the inner conductor part 8 can basically be provided in a similar or identical manner.

In the exemplary embodiment it is shown that the plug body 4 accommodates a single inner conductor part 8. Of course, the plug body 4 can also accommodate a plurality of inner conductor parts 8 which are connected to a corresponding number of inner conductors 9.

Furthermore, it is shown in the exemplary embodiment that the connector 1 receives a connector body 4. In principle, it can also be provided that the plug connector 1 accommodates a plurality of plug bodies 4. The embodiment is to be understood accordingly.

As from the figures, especially from the Figures 1 , 4th , 8th and 13 As can be seen, the housing 3 has a receptacle 10 for the insertion of the plug body 4. In the exemplary embodiment, the receptacle 10 is designed as a bore which extends axially through the housing 3. In the exemplary embodiment, it is also provided that the plug body 4 can be moved along its longitudinal axis or in the axial direction A (cf. Figure 13 ) is inserted into the housing 3 or the receptacle 10 of the housing 3. The plug body 4 and the receptacle 10 are designed in such a way that an end position of the plug body 4 is fixed in the receptacle 10. To determine the end position, it is preferably provided that the plug body 4 noticeably engages in the receptacle 10 in its end position. In the exemplary embodiment it is provided for this purpose that the housing 3 has at least one latching element 11 (cf. Figure 4 ), which evades laterally or radially when inserting the plug body 4 and lets the plug body 4 through, but returns to its previous or undeflected position when the plug body 4 reaches the end position, preferably springs back in such a way that the locking element 11 dem Plug body 4 stands in the way when it is withdrawn against the direction of insertion. The latching element 11 can preferably be designed in such a way that it can be operated and thus possibly deflected, for example by inserting a screwdriver in order to enable the plug body 4 to be removed from the housing 3 or the receptacle 10 again if necessary.

The plug body 4 preferably has a taper 12 into which the latching element 11 penetrates when the plug body 4 has reached its end position in the receptacle 10. This can also be any recess, a recess or the like. The formation of a preferably annular circumferential taper 12 has, however, proven to be particularly suitable. The taper 12 can also be produced, for example, in that the plug body 4 has a two-part or multi-part structure, the taper 12 preferably being formed in the connection area between two parts of the plug body 4.

In the exemplary embodiment it can be provided that the receptacle 10 and the plug body 4 have mechanical codings, so that the insertion of a plug body 4 not intended for the housing 3 is mechanically prevented.

According to the invention, a contact element 13 is provided which can be inserted into the housing 3 in such a way that a front region 13a of the contact element 13 makes electrical contact with the plug body 4 inserted in the housing 3 on its outer circumference. The contact element 13 is connected to the fastening means 2 in an electrically conductive manner. As a result, a ground connection with a further component 24 (cf. Figure 14 ), e.g. B. a conductive body part of a vehicle. The front region 13a of the contact element 13, which comprises the outer circumference of the plug body 4, is particularly good in FIG Figure 1 , 7th and in the Figure 12 shown. In the horizontal longitudinal section shown, FIG. 4 shows only a short section of the front area 13a of the contact element 13, which is otherwise covered by the plug body 4 shown in section.

The Figures 5 , 7th , 9 , 10 and 12 show the contact element 13, in particular the front region 13a of the contact element 13, without the plugged-in connector body 4.

A connection of the contact element 13 to the fastening means 2 is in particular the Figures 2 , 6th , 7th , 9 , 10 and 11 removable.

In the variant of the Figures 12 to 14 however, as already mentioned, the contact element 13 with the fastening means 2 is preferably formed in one piece.

In the exemplary embodiment, the front region 13a of the contact element 13 is positively connected to at least part of the outer circumference of the plug body 4. The front area 13a of the contact element 13 is designed as a terminal 13a. The terminal 13a has two clamping arms, which are preferably designed to be resilient and for connection to the outer circumference of the plug body 4 are deflected from their relieved position and, after connection to the outer circumference of the plug body 4, spring back as far as possible and thus take up or encompass the plug body 4 between them.

The contact element 13 can in principle contact the plug body 4 at any position. In the exemplary embodiment it is provided that the contact element 13 or its terminal 13a engages in the taper 12 of the plug body 4. In the exemplary embodiment, the locking element 11 also engages in the same taper 12, but this is not absolutely necessary. Different tapers, depressions, recesses or the like can also be involved here. The use of a common taper 12 can, however, be structurally and thus economically advantageous.

In the exemplary embodiment, it is provided that the contact element 13 is positioned in the housing 3 in such a way that the contact element 13 engages in the taper 12 when the plug body 4 has reached its end position, whereby a connection dimension of the plug body 4 is also ensured.

As from the Figures 1 to 11 It can also be seen that the connector 1 in this variant has a securing element 14 which is inserted into a recess 15 (see FIG Figure 4 and Figure 8 ) of the housing 3 can be introduced in such a way that a movement of the housing 3 relative to the securing element 14 is limited at least in one degree of freedom. The limitation of the movement of the housing 3 with respect to the securing element 14 in at least one degree of freedom, preferably at least in the direction of movement for sliding the plug body 4 in and out, is particularly advantageous if the securing element 14 is attached to the fastening means 2 directly and / or via the contact element 13 is fixed. In this case, a movement of the housing 3 with respect to the fastening means 2 is already limited by the securing element 14, preferably at least in the mentioned direction of movement or longitudinal direction or axial direction A of the housing 3.

The securing element 14 and the recess 15 of the housing 3 are preferably designed in such a way that the movement of the housing 3 with respect to the securing element 14 is also limited in further degrees of freedom. Furthermore, it can be provided that the securing element 14, when it is fully inserted into the recess 15, latches in the intended end position in the housing 3. A locking hook can be provided for this purpose. The latching hook can preferably be detachable in order to remove the securing element 14 again from the recess 15 or the housing 3.

By essentially positively receiving the securing element 14 in the recess 15 and the locking hook, it can be provided that the securing element 14 and the housing 3 are essentially immovably connected to one another.

As can be seen in particular from the representation of the Figure 4 results, at least part 14a of the securing element 14 protrudes into a displacement path of the plug body 4 introduced into the housing 3. In the exemplary embodiment, a part 14a of the securing element 14 protrudes into the taper 12 so that the plug body 4 can be pulled out of the housing 3 or . Is blocked from the receptacle 10 by the part 14a.

In the exemplary embodiment, it is shown that both the contact element 13 and the securing element 14 are connected to the plug body 4 by an orthogonal movement.

The contact element 13 and also the securing element 14 thus extend orthogonally in the direction of the plug body 4 when the latter is inserted into the housing 3 in the end position.

The part 14a of the securing element 14, like the clamp 13a and the latching element 11, protrudes into the same taper 12, but this is optional.

As in particular from the Figures 2 , 6th , 9 and 10 As can be seen, the contact element 13 is in the variant of FIG Figures 1 to 11 inserted positively into a recess 17 of the fastening means 2. Alternatively, the contact element 13 can also be connected to the fastening means 2 in any desired manner, for example by soldering, gluing or riveting. The contact element 13 can also be formed in one piece or in one piece with the fastening means 2. A one-piece training is in the variant of Figures 12 to 14 shown.

The positive connection shown in the exemplary embodiment produces a good mechanical and electrically conductive connection between the contact element 13 and the fastening means 2.

In all exemplary embodiments, the fastening means 2 and also the contact element 13 are preferably designed to be at least partially electrically conductive, and the fastening means 2 and also the contact element 13 are preferably at least partially made of an electrically conductive metal. The fastening means 2 and / or the contact element 13 is preferably formed essentially completely, particularly preferably completely, from metal.

The form-fitting connection of the contact element 13 to the recess 17 of the fastening means 2 can be produced particularly advantageously in that the contact element 13 is designed to be resilient and has a taper 18, into which the edge of the recess 17 engages, around the contact element 13 in the recess 17 to fix. The contact element 13 preferably has, as in the exemplary embodiment according to FIGS Figures 1 to 11 shown, an embodiment with two clamping arms, which are mirror images of each other and each have a taper 18 in which the edge of the recess 17 engages, as shown in FIG Figure 2 can be seen.

Alternatively, the contact element 13 can also have a projection and the recess 17 can be designed in a correspondingly complementary manner to produce a form-fitting connection.

Like the one in particular Figure 8 and the Figure 9 As can be seen, the securing element 14 can have a passage 19 in order to insert the contact element 13 and to connect its front area, ie the terminal 13a, to the plug body 4. This has the advantage that the housing 3 does not have to have an additional recess for the contact element 13 to pass through, but rather the passage 19 can be formed in a simple manner in the securing element 14, which is already located in a recess 15 of the housing 3 anyway. The contact element 13 is thus inserted into the housing 3 in the sense of the invention through the presence of the passage 19 in the securing element 14.

In the embodiment according to Figures 1 to 11 the passage 19 is formed in two parts, so that a passage is created for each clamping arm of the contact element 13.

In this embodiment, the securing element 14 is preferably made of plastic. The securing element 14 is preferably not electrically conductive in this embodiment.

The Figure 7 shows an alternative embodiment of the securing element 14. It is shown in FIG Figure 7 a relatively flat design of the securing element 14, but this is not primarily important here. The embodiment of Figure 7 differs from the exemplary embodiment described above essentially in that the contact element 13 is inserted into a recess 20 of the securing element 14. The contact element 13 can be designed in the manner as has already been described in the exemplary embodiment, in which case an edge of the recess 20 of the securing element 14 engages in the taper 18 of the contact element 13 or its mirror-inverted clamping arms around the To receive contact element 13 in recess 20 in a form-fitting manner.

In the in Figure 7 The illustrated embodiment, no direct connection between the contact element 13 and the fastening means 2 is provided. The electrical connection between the contact element 13 and the fastening means 2 takes place in the exemplary embodiment according to FIG Figure 7 Via the securing element 14. For this purpose, the securing element 14 is at least partially electrically conductive, preferably at least partially made of metal, particularly preferably essentially or completely made of metal. The contact element 13 can be loosely positioned in a recess 17 of the fastening means 2. It can be provided that the securing element 14 is connected to the fastening means 2 by a snap connection, for example. The connection can also be made in other ways. In principle, a fixed connection between the securing element 14 and the fastening means 2 can also be completely dispensed with. This is possible in particular when the housing 3 is connected to the fastening means 2 in such a way that the securing element 14 is clamped between the housing 3 and the fastening means 2 and is thereby fixed accordingly.

In principle, the securing element 14 can also be used in the exemplary embodiment according to FIG Figure 7 so inserted into a recess 15 of the housing 3 that a movement of the housing 3 relative to the securing element 14 is limited at least in one degree of freedom. The securing element 14 in the embodiment according to Figure 7 can also be designed in such a way that it has a part 14a which penetrates into a displacement path of the plug body 4 introduced into the housing 3 when the securing element 14 is positioned accordingly.

As from the Figures 1 to 11 As can be seen, the fastening means 2 can have a support 21 and / or at least one snap connection part 22 for fastening the housing 3 of a plug connector 1. In the embodiments of the variant of Figures 1 to 11 Both a support 21, on which an underside of the housing 3 can be placed, and a snap connection part 22, which is designed as a snap hook in the exemplary embodiment, are provided. The support 21 can have a securing edge in order to additionally limit, in particular, a horizontal movement of the housing 3.

The fastening means 3 can also have at least one eyelet 23 or also several eyelets 23, which can be provided to electrically and mechanically connect the fastening means 2 to a mass part or to the further component 24, for example a vehicle mass or the like.

The Figures 9 to 11 show an embodiment of the fastening means 2 for receiving and fastening as well as for making electrical contact with a plurality of connectors 1. In the exemplary embodiment, three connectors 1 are shown, but the invention is not limited to the specific number of connectors 1 that a fastening means 2 can accommodate. In the embodiments according to Figures 9 to 11 the fastening means 2 has two eyelets 23. Alternatively, only one or more eyelets 23 can be provided. Furthermore, the design of the eyelets 23 or their presence in all fastening means 2 is optional. The eyelets 23 can optionally be omitted completely, but it is advantageous if the fastening means 2 has connecting elements in order to attach the fastening means 2 in a simple manner to a mass part or to the further component 24.

As can be seen from the exemplary embodiments with regard to the variant of Figures 1 to 11 results, the plug body 4 can be secured, as long as the securing element 14 and the contact element 13 are not yet brought up to the plug body 4, by a corresponding design of the housing 3, in particular by the latching element 11. This is known as the primary backup.

After the securing element 14 and / or the contact element 13 have been pushed into their end position, the plug body 4 previously positioned in the housing 3 can be secured by them. This is referred to as secondary fuse, with an interaction of the contact element 13 and the fuse element 14 being particularly suitable for this. The contact element 13 and the securing element 14 can also be responsible for the positionally precise seating of the plug body 4 in the housing 3 and thus also ensure the connection dimensions for connecting to a complementary connector, not shown in detail.

The Figure 8 shows the securing element 14 in a so-called pre-locking position. The securing element 14 is preferably preassembled in the housing 3. To assemble the plug body 4, it is provided that the plug body 4 is first inserted into the housing 3 and then, when the plug body 4 has reached its end position in the housing 3, the secondary fuse 14 is pressed in until it is finally locked.

Then, as in Figure 9 and 10 shown by way of example, the connector 1 can be clipped onto the contact element 13, which is already connected to the fastening means 2.

In the variant that is included in the Figures 12 to 14 is shown, a securing element 14 can be dispensed with.

The Figures 12 shows a special variant of the fastening means 2, which is basically preferred. Figure 13 shows a housing 3 and 3 suitable for this variant Figure 14 represents the fastening means 2 and the housing 3 in an assembled position. All of the features already described above can of course be combined with the features of this variant, unless this is technically excluded.

The fastening means 2 of this variant also has a contact element 13 which, however, is now preferably formed in one piece with the fastening means 2. Furthermore, two snap connection parts 22 are provided for fastening the housing 3 of the plug connector 1, which for this purpose encompass the housing 3 on the outside. The housing has a groove 25 in its outer side, into which the snap connection parts 22 can penetrate in order to form a positive connection in the axial direction A between the housing 3 and the fastening means 2. The snap connection parts 22 are also preferably designed in one piece with the fastening means 2. It can also be provided that the snap connection parts 22 are designed as any connection elements and in particular in such a way that they penetrate into the housing 3 and thereby establish a mechanical, in particular form-fitting and / or force-fitting connection between the fastening means 2 and the housing 3.

Finally, the fastening means 2 has connecting elements 26 in order to form the ground connection with the further component 24. In the present case, the connecting elements are designed as crimp connections 26 and are likewise preferably in one piece with the fastening means 2.

A ground connection cable 27 can preferably be crimped onto the fastening means 2 via the crimp connection 26 in order to form the ground connection with the further component 24 (cf. Figure 14 ). For this purpose, the ground connection cable 27 can preferably have a cable lug 28 (or the like) for electrical and mechanical fastening to the further component 24 at the end that is not crimped to the fastening means 2.

The fastening means 2, in particular according to the variant of FIG Figures 12 to 14 , be designed as a thin sheet metal. The fastening means 2 can be designed as a stamped and bent part.

The housing 3 of the connector 1 and the fastening means 2 are preferably designed in such a way that the fastening means 2, when it is inserted into the housing 3 of the connector 1, does not protrude beyond the outer sides of the housing 3 of the connector 1, preferably is set back.

The housing 3 can have suitable depressions and / or recesses for this purpose, as shown in FIG Figures 13 and 14 is recognizable.
