Description

The invention relates to a connector, in particular a mini-coax automotive connector, for connection to a compatible connector device, and a system consisting of a connector and a compatible connector device.

Connectors, in particular connectors for automotive applications, have to meet a large number of requirements. For example, connectors must enable safe and reliable transmission of electrical signals, such as high-frequency signals. Furthermore, the plug connectors must be durable and, due to the usually limited space available at the intended installation site, have small dimensions and be designed as compactly as possible.

Furthermore, standards for connectors are gaining ground in the automotive sector. For example, standardized FAKRA (plug) connectors are known. FAKRA is a standards committee for automotive technology in the German Institute for Standardization, which represents international standardization interests in the field of automotive technology. The FAKRA standard provides a shape-coding and color-coding based system for correctly attaching plug assemblies to connectors. For example, a plug connector can have a form coding according to which a corresponding plug device can be connected to the plug connector. The shape coding ensures that the plug device can only be connected to the plug connector in accordance with one plug-in option. Furthermore, the coding of the plug connector and the complementary plug device can be carried out in accordance with desired FAKRA standards.

Connectors used in the automotive sector and installed on printed circuit boards in particular, but can lead to problems due to their own weight. For example, the electrical connection between the plug connector and the printed circuit board can be overly stressed by vibrations and centrifugal forces, which can disrupt the connection. For example, solder joints between the connector and the circuit board can break or come loose. Furthermore, forces can be transmitted to the printed circuit board via the connector, for example due to vibrations, which leads to premature aging of the printed circuit board.

It is therefore desirable to provide connectors that have the lowest possible intrinsic weight but are nevertheless designed to be resistant and robust.

This object is solved by the subject matter of the independent claims. Preferred embodiments are defined in the dependent claims.

• einen als Zink-Druckguss-Bauteil ausgeführten Gehäusekörper, welcher mindestens zwei Koax-Steckverbinder zum Verbinden mit entsprechenden Koax-Buchsen der kompatiblen Steckervorrichtung aufweist, wobei die Koax-Steckverbinder parallel zueinander ausgerichtet sind und sich ausgehend vom Gehäusekörper in Richtung einer Verbindungsrichtung erstrecken,
• wobei der Gehäusekörper zwei gegenüberliegende Hauptseiten aufweist, welche im Wesentlichen parallel zur Verbindungsrichtung ausgerichtet sind und welche jeweils von einer Oberseite zu einer Unterseite des Gehäusekörpers verlaufen, und
• wobei jede Hauptseite eine oder mehrere Aussparungen aufweist.

One aspect of the invention relates to a connector, in particular a mini-coax automotive connector, for connecting to a compatible connector device, having:

• a housing body designed as a zinc die-cast component, which has at least two coax connectors for connection to corresponding coax sockets of the compatible connector device, the coax connectors being aligned parallel to one another and extending from the housing body in the direction of a connection direction,
• wherein the housing body has two opposite major sides which are oriented substantially parallel to the connection direction and which each extend from a top to a bottom of the housing body, and
• each major face having one or more recesses.

Advantageously, by providing one or more recesses on the main sides of the housing body, the dead weight of the housing body can be reduced. Furthermore, the stability and integrity of the Housing body is not negatively affected by the one or more recesses substantially. Furthermore, the amount of material used in the production of the housing body can be reduced, so that the plug connector can be produced more cost-effectively. The recesses can be designed in particular as indentations which are formed on the outer wall or on the main sides of the housing body.

In the context of the present disclosure, the mating direction refers to the direction in which the connector must essentially be guided in order to connect the connector to the compatible connector device. Furthermore, the upper side and the lower side of the housing body can run essentially parallel to the connection direction and can be arranged opposite one another. Furthermore, the top and bottom are each arranged substantially perpendicular to the main sides of the housing body.

The connector can preferably be mechanically and electrically connected to a printed circuit board. The housing body can, for example, have plug-in contacts that are inserted into corresponding plug-in holes in the printed circuit board in order to connect the connector to the printed circuit board. In particular, the plug contacts can be formed on the underside of the housing body, with the underside pointing in the direction of the printed circuit board when the housing body or the connector is attached to the printed circuit board. Furthermore, the main sides of the housing body are aligned substantially perpendicularly to the circuit board when the housing body or connector is attached to the circuit board.

Furthermore, it can be provided that the at least two coaxial connectors are electrically connected to the printed circuit board, for example by soldering the two coaxial connectors to the printed circuit board.

The longitudinal direction of the one or more recesses can preferably run essentially perpendicular to the connection direction.

Preferably, each main side can have a first pair of recesses, which start from the top towards the bottom of the Housing body extends, and / or each main side may have a second pair of recesses, which extends from the bottom toward the top.

In other words, the first pair of cutouts and the second pair of cutouts each have exactly two cutouts. Furthermore, the cavities of the first pair of cavities may be identical but spaced apart from each other. Likewise, the recesses of the second pair of recesses can be identical but spaced apart from one another. In particular, the cutouts of the first pair of cutouts and the second pair of cutouts are spaced from each other along the connecting direction.

Preferably, the first pair of recesses and the second pair of recesses may not be continuous on the main side, and/or the first pair of recesses and the second pair of recesses face each other on the main side. In other words, the first pair of recesses and the second pair of recesses are not continuously formed from the top to the bottom.

Preferably, the width of one notch of the first pair of notches and/or the width of one notch of the second pair of notches is 0.04 to 0.08 times, and more preferably 0.057 times the total width of the housing body along the connecting direction. The overall width of the housing body can also be viewed as the distance between two notional planes, each of which is perpendicular to the connection direction, and where a first notional plane of the two notional planes is at a connection-direction end of the housing body (without coax connectors) and a second fictitious plane of the two fictitious planes lies at an end of the housing body opposite to the connection direction. The overall width of the housing body can be, for example, in the range between 11 mm and 18 mm and preferably in the range between 13 mm and 16 mm. The overall width of the housing body can particularly preferably be approximately 15.8 mm, the width of a cutout of the first pair of cutouts and the width of a cutout of the second pair of recesses are substantially 0.9 mm.

Preferably, the depth of a recess of the first pair of recesses can be 0.10 to 0.14 times the distance of the two opposite major sides, and/or the depth of a recess of the second pair of recesses can be 0.045 to 0.07 times the distance between the two opposite main sides. In a particularly preferred embodiment, the recess depth of the first pair of recesses may be about 0.117 times the spacing of the two opposite major sides and the depth of a recess of the second pair of recesses may be about 0.055 times the spacing of the two opposite major sides . Consequently, the recesses in the lower area of the connector are less deep than in the upper area of the connector. This is particularly advantageous since it does not adversely affect the stability and integrity of the housing body. Furthermore, the deeper recesses in the upper area of the housing body relative to the printed circuit board lead to a greater weight saving than in the lower area of the housing body, which is advantageous in view of the larger distance between the upper area and the printed circuit board. For example, the distance between the two main sides of the housing body can be 10 mm to 13 mm. In the particularly preferred embodiment, the distance between the two main sides of the housing body 12 can be about 12 mm, and the depth of a recess of the first pair of recesses is about 1.41 mm, and the depth of a recess of the second pair of recesses is about 0. be 66 mm.

Preferably, the first pair of recesses and the second pair of recesses are spaced at least 0.15 times and at most 0.25 times the total width of the housing body from a rear side of the housing body. The side of the housing body which is essentially perpendicular to the connection direction and points in the opposite direction to the connection direction can be regarded as the rear side of the housing body.

The length of the first pair of recesses can preferably correspond to 0.2 to 0.4 times, preferably 0.3 to 0.38 times, the distance between the bottom and the top of the housing body, and/or the The length of the second pair of recesses can be 0.3 to 0.5 times, preferably 0.3 to 0.44 times, the distance between the bottom and the top of the housing body. In a particularly preferred embodiment, the length of the first pair of recesses may be approximately 0.37 times the distance between the bottom and top of the housing body 12 and the length of the second pair of recesses may be approximately 0.36 times the distance between correspond to the bottom and the top of the case body. For example, the distance between the underside of the housing body and the top side of the housing body can be 10 mm to 14 mm, preferably 11 mm to 13 mm. In the particularly preferred embodiment, the distance between the bottom of the housing body and the top of the housing body can be substantially 12.05 mm, the length of the second pair of cutouts can be approximately 5.7 mm and the length of the first pair of cutouts can be approximately 4.45 mm can be.

Preferably, the spacing between the gaps of the first pair of gaps can be 1.3 to 2.0 times the width of a gap of the first pair of gaps.

The distance between the cutouts of the second pair of cutouts can preferably be 1.3 times to 2.0 times the width of a cutout of the second pair of cutouts.

Preferably, the depth of the first pair of recesses may be greater than the width of the first pair of recesses and/or the depth of the second pair of recesses may be less than the width of the second pair of recesses.

The housing body can preferably be designed to dissipate heat from the printed circuit board. In particular, one or more support elements with a support surface for supporting the housing body on a printed circuit board can be formed on the underside of the housing body, so that the coaxial connectors, which are preferably used for electrical contacting, and the plug contacts do not additionally bear the weight of the connector or the housing body have to "wear". Furthermore, the support surfaces contact the Circuit board when the housing body is attached to the circuit board, whereby the support elements and / or the plug contacts for heat dissipation from the circuit board can be used.

The connector can preferably have a connection housing that can be connected to the housing body for connecting the connector to the compatible connector device, the connection housing surrounding the at least two coaxial connectors at least in sections along the direction of connection, the connection housing having exactly one insertion option for inserting the compatible connector device in order to to connect the coax connectors to the corresponding coax sockets when the compatible plug device is plugged into the connection housing according to the exactly one insertion possibility, wherein the connection housing can be connected to the housing body in at least two different orientations and wherein each orientation of the two different orientations has a caused by the other orientation different assignment of at least two coax connectors to the coax jacks of the compatible connector device.

Advantageously, the connector can be preconfigured with a predetermined orientation of the connection housing on the housing body, so that based on the selected orientation, the compatible connector device can be plugged into the connector in a specific spatial arrangement direction with respect to the connector. For example, it is thus possible for a plug device angled at right angles to point away from the plug connector in different directions, depending on the selected orientation. In particular in places where there is limited space, for example in the automotive sector, the plug connector allows an orientation to be selected in which the plug device can be used under the given space conditions. For example, it can be provided that the plug connector can be arranged on a printed circuit board in order in particular to electrically connect the coaxial plug connector to the printed circuit board and electrical components arranged thereon. Due to the possibility of choosing the orientation of the connection housing in order to use existing space optimally, it is possible to possibly necessary and mostly complex revision of the circuit board layout, in particular the provision of a different fastening position or arrangement position of the connector on the circuit board, can be dispensed with. If necessary, only the electrical connection between the connector and the printed circuit board has to be adjusted, for example by changing the wiring on the printed circuit board side to connect the individual coaxial connectors to the printed circuit board. However, in comparison to a revision of the circuit board layout, in which the connector has to be arranged in a different position on the circuit board, this is much less complex.

Consequently, the connector allows the connector device to be connected to the connector in a predetermined spatial orientation in relation to the connector, in order to be able to react flexibly to given space conditions.

The plug connector can preferably be designed as a standard-compliant plug connector, which in particular conforms to a standard of the automotive sector, for example FAKRA HF and USCAR and in particular conforms to the standards DIN 72594-1 and USCAR-18.

To arrange the connector on a printed circuit board, a first end of a coaxial connector can be connected to the coaxial sockets of the compatible connector device, and a second end of the coaxial connector can be electrically connected to a printed circuit board. In particular, the coaxial connector can have an electrically conductive sleeve at the first end, in which an electrically conductive inner contact is arranged at least in sections. The electrically conductive inner contact can be electrically insulated from the sleeve by means of a first dielectric insulation element. In particular, it can be provided that the sleeve and the inner conductor can be connected to a coaxial socket both electrically and mechanically. Furthermore, the electrically conductive inner contact can have a pin-shaped end in the region of the sleeve, which can be inserted into an inner conductor of the coaxial socket.

The coax connectors are preferably designed to transmit high-frequency signals, for example GPS, mobile phone and/or radio signals. For example, the coax connectors can be designed to transmit high-frequency signals up to a frequency of 6 GHz.

In order to enable the compatible plug device to be plugged into the connection housing in exactly one way, the connection housing can have a coding (shape coding) predetermined by its shape. The coding ensures that the compatible plug device, which has a (shape) coding that is complementary to the coding of the connection housing, can be plugged into the connection housing in exactly one insertion option. In the context of the present invention, an insertion direction corresponds to the direction in which the compatible connector device is inserted into the connector housing. In this case, the direction of insertion and the direction of connection are opposite.

The connection housing can preferably be slipped onto a receiving base provided on the housing body and the connection housing and the receiving base can each have cooperating securing features with which the connection housing can be secured on the receiving base or the housing body.

Advantageously, the safety features formed on the receiving base and the safety features formed on the connection housing, which interact, make it more difficult or prevent accidental detachment or removal of the connection housing from the housing body, so that the preselected orientation of the connection housing on the housing body is maintained.

The connection housing can preferably be detached from the housing body in a non-destructive or non-destructive manner. In particular, the security features formed on the receiving base and the security features formed on the connection housing can be designed to provide a non-destructive To allow or prevent detachment of the connector housing from the housing body.

Preferably, the mounting base can be formed on a side of the housing body pointing in the connection direction, and the at least two coaxial plug connectors can extend from the mounting base in the direction of the connection direction.

The housing body can thus have a main housing body section, which is adjoined by the receiving base lying in the connection direction. In particular, the main housing body section can be configured essentially in the form of a cube. Furthermore, the coax plug connectors can be arranged at least in sections in the housing body, with the first end of the coax plug connectors being guided outwards via the receiving base in the connection direction. Furthermore, the second end of the coaxial plug connector can be guided to the outside via an underside of the housing body or the main housing body section. The underside of the housing body corresponds to the side of the housing body which faces the printed circuit board when the connector is arranged on a printed circuit board. Furthermore, the coaxial connectors, in particular the second end of the coaxial connectors, can be electrically connected to the printed circuit board, for example by means of a material connection, in particular soldering, to the printed circuit board.

Further, the first pair of recesses and the second pair of recesses may be formed on the main case body portion.

The receiving base can preferably have a front side which is essentially perpendicular to the connection direction and from which the at least two coaxial plug connectors extend in the direction of the connection direction. Furthermore, the receiving base can have narrow sides which, starting from the front, extend counter to the connection direction and connect the front to a section of the housing body that adjoins the receiving base, the main housing body section. Further the securing features on the receiving base or the securing features of the receiving base can be formed on the narrow sides. Furthermore, the narrow sides and the front spatially delimit the receiving base.

Furthermore, the front side of the receiving base can have one or more passage openings, by means of which the coaxial plug connectors can be guided out of the housing body. In particular, the front side can have a number of passage openings which corresponds to the number of coaxial connectors. In particular, each coax plug connector can be guided out of the housing body through a separate passage opening. Furthermore, the normal vector of the front side runs essentially parallel to the connection direction or plug-in direction.

Furthermore, the longitudinal direction of the sleeve or the longitudinal direction of the first end of the coaxial connector can be aligned essentially parallel to the connection direction or essentially perpendicular to the front side of the receiving base. In other words, the longitudinal direction of the sleeve or the longitudinal direction of the first end of the coaxial connector is essentially parallel to the normal vector of the front side of the receiving base.

In a preferred embodiment, the front side of the mounting base has an essentially rectangular shape, particularly preferably a square shape, with four narrow sides extending from the front side of the mounting base in the direction of the housing body or the main housing body section. In particular, one narrow side in each case extends from one side of the essentially rectangular or essentially square-shaped front side of the receiving base in the direction of the housing body or the main housing body section.

Preferably, the connection housing can have a receiving socket-side section for inserting the receiving socket and a connector device-side section for inserting the connector device, wherein between the receiving socket-side section and the connector device-side portion is formed substantially perpendicular to the connection direction arranged partition, and wherein the partition has through-openings through which the at least two coaxial connectors extend when the connection housing is connected to the housing body.

Advantageously, by providing the dividing wall with passage openings through which the coax connectors are guided and by providing a section on the connection housing on the receiving base side, the connection housing can be arranged particularly stably on the housing body. Furthermore, it can be provided that the section of the connection housing on the connector device side has exactly one insertion possibility for inserting the compatible connector device. That is to say, the section of the connection housing on the connector device side can have a coding which is predetermined by the shape of the section on the connector device side and which is compatible with a complementary coding of the connector device. For example, the section on the connector device side can have one or more grooves running along the connection direction on an inside, which function as a form coding.

Preferably, in the connected state of the connection housing and the housing body, the receiving socket can be completely inserted or plugged into the section of the connection housing on the receiving socket side in the connection direction. Furthermore, the coaxial plug connectors are surrounded at least in sections by the section of the connection housing on the plug device side. In particular, the first end of the coaxial connector is set back from an end of the connector-device-side portion of the connector housing that is in the direction of connection.

The section of the connection housing on the receiving base side preferably has an outer wall which, together with the partition wall, forms a receiving space into which the receiving base can be inserted, the outer wall being arranged essentially perpendicularly to the partition wall and the securing features being arranged on the inside of the outer wall.

Furthermore, in the connected state of the connection housing and the housing body, the partition wall can bear against the front side of the mounting base and the outer wall of the section on the mounting base side can bear essentially on the narrow sides of the mounting base.

Preferably, the securing features of the socket include at least one socket-side projection and the securing features of the connector housing at least one connector housing-side recess, wherein the socket-side projection and the connector housing-side recess engage with each other when the connector housing is connected to the housing body.

In particular, the projections on the receiving base can be formed on the narrow sides of the receiving base. Furthermore, the projections on the receiving base can have a ramp that descends in the direction of connection and descend in steps on the narrow side counter to the direction of connection. Advantageously, a non-destructive separation of the connection housing from the housing body can thus be made possible in order to be able to detect any tampering with the plug connector. In particular, separating the connection housing from the housing body can lead to damage to the projections on the receiving base and/or the cutouts on the connection housing side.

In a preferred embodiment, the plug connector or the housing body can have four coax plug connectors, in particular exactly four coax plug connectors, which are routed outwards through the receiving base in the connection direction. The four coax connectors are arranged parallel to each other. Furthermore, the front side of the receiving base is essentially square and each quadrant of the front side can have a passage opening through which one of the four coaxial connectors is guided to the outside. Likewise, the partition wall of the connection housing can have four passage openings through which the four coaxial connectors protrude when the connection housing is connected to the housing body.

Furthermore, it can be provided that the connecting housing can be connected to the housing body in four different orientations. In particular, the four orientations can differ in that the connection housing is rotated by 90° relative to the housing body.

Preferably, the housing body can have (precisely) one positioning projection and the connecting housing can have at least two positioning openings, the positioning projection and the at least two positioning openings being arranged in such a way that in each orientation in which the connecting housing can be connected to the housing body, the positioning projection can move into a different positioning opening which engages at least two positioning openings.

The provision of the positioning projection and the at least two positioning openings advantageously enables the connection housing to be positioned or aligned exactly on the housing body.

Preferably, the positioning projection is formed on the front side of the receiving base, and the at least two positioning holes are provided in the partition wall of the connection housing. Specifically, the positioning protrusion extends in the connection direction from the front side of the receiving base and engages with one of the two positioning holes when the connection housing is connected to the housing body.

The front side of the receiving base preferably has (precisely) two positioning projections which extend from the front side in the connection direction. Furthermore, the partition wall of the connection housing has four positioning openings, with each positioning projection engaging in a different positioning opening in each possible orientation of the four orientations of the connection housing and the housing body.

The positioning projections are preferably arranged on different edges, which are formed between the front side of the receiving base and the different narrow sides. In particular, the positioning projections are arranged centrally on the respective edges. Furthermore, the two positioning projections can be arranged on opposite edges, namely a first positioning projection on a first edge and the second positioning projection on the second edge opposite the first edge. Accordingly, the positioning holes are arranged on the partition wall of the connection box.

The combination of exactly two positioning projections and exactly four positioning openings is advantageous since the connection housing can be positioned precisely on the housing body in each of the four different orientations.

Preferably, the positioning projections and the positioning openings essentially have the shape of an isosceles triangle, in particular an equilateral triangle. The selected triangular shape is advantageous since the positioning projections and positioning openings are exposed to or have a small amount of distortion when the connection housing and/or the housing body are exposed to possible mechanical forces, in particular shearing loads.

One side of the positioning projection, which is designed as a triangle, is preferably aligned along the edge which is formed by the front side and a narrow side of the receiving base. In the case of the shape of an isosceles triangle, the base side or base of the isosceles triangle is preferably aligned along the edge. Furthermore, the positioning projection can be aligned centrally on the edge and one corner of each of the two opposing positioning projections point towards one another.

The housing body can preferably be designed for mounting on a printed circuit board, with the focus of the connector preferably being behind a printed circuit board setting edge of the housing body. The connector or the housing body can thus advantageously be arranged on the printed circuit board to be connected without the connector tilting in relation to the printed circuit board. This simplifies the attachment or assembly of the plug connector on the printed circuit board, since the plug connector on the printed circuit board does not have to be secured against tilting.

In particular, the housing body can have a plurality of plug-in contacts which are designed to be inserted into corresponding plug-in holes in the printed circuit board in order to connect the connector to the printed circuit board. The housing body preferably has four plug contacts, of which two first plug contacts are arranged lying in front of two second plug contacts in the connection direction. An imaginary connecting line, which connects the two first plug contacts, which are arranged at the same height on the underside in the connecting direction, can be seen as the printed circuit board setting edge.

The connection housing can preferably be designed in one color. Furthermore, the color can correspond to a color coding according to a standard. Advantageously, a color coding of the connector can thus be made available in addition to the shape coding.

In a preferred embodiment, the housing body can be designed as a zinc die-cast component and/or the connecting housing can be designed as a plastic component.

Preferably, the case body may include a first case body member and a second case body member, the second case body member being inserted into the first case body member. Furthermore, the first housing body element can have the receiving base and the second end of the coaxial plug connector can be guided to the outside through the second housing body element, in particular via the underside.

Preferably, the first pair of recesses and the second pair of recesses may be formed on the first case body member.

Furthermore, the electrically conductive inner contact can have a first contact section which is angled at a predetermined angle relative to a second contact section of the inner contact. The first contact section is arranged at least in sections in the sleeve and the second contact section can be electrically connected to the printed circuit board via the second end of the inner conductor. Furthermore, the first dielectric insulation element surrounds the first contact section at least in sections and is arranged in the sleeve at least in sections. Furthermore, the connector can have a second dielectric insulation element, which at least partially surrounds the second contact section. The first dielectric insulation element and the second dielectric insulation element can be arranged on the inner contact in such a way that angling of the first contact section relative to the second contact section is limited to the predetermined angle.

Preferably, the first dielectric insulation element and the second dielectric insulation element each have a stop surface, which are aligned essentially parallel to one another when the predetermined angle is present.

The first dielectric insulation element and/or the second dielectric insulation element are preferably formed or attached to the first contact section or to the second contact section by means of an injection molding process.

The first housing body element preferably has deformable securing elements with which the second housing body element is secured to the first housing body element, the deformable securing elements preferably being arranged on the underside of the first housing body element.

Another aspect of the invention relates to a system consisting of a connector according to the above statements and one with the Connector compatible plug device.

An embodiment of the invention is described in more detail below with reference to the accompanying figures. It goes without saying that the present invention is not limited to this embodiment and that individual features of the embodiment can be combined to form further embodiments within the scope of the appended claims.

a second embodiment of the housing body.

figure 1 shows a connector 10 consisting of a housing body 12 and a connection housing 14, which can be plugged onto the housing body 12. The connector 10 is designed in particular as a mini-coax automotive connector and can be connected to a compatible connector device. The housing body 12 further consists of a main housing body section 16 and a receiving socket 18 which is arranged on the main housing body section 16 and points in the direction of a connection direction V. The connection direction V is to be understood as the direction in which the connector 10 must be moved in order to insert the housing body 12 into the connection housing 14 or to connect the connector 10 to a compatible connector device (not shown).

Furthermore, the housing body 12 has four coaxial plug connectors 20 which are arranged in the housing body 12 at least in sections. The four coaxial plug connectors 20 are aligned essentially parallel to one another and are guided outwards from the housing body 12 via the receiving base 18 . The four coax connectors 20 extend from the receiving base 18 in the connection direction V.

The connection housing 14 has a section 22 on the receiving base, which can be plugged onto the receiving base 18 . In the connected state of the connecting housing 14 with the housing body 12 , the section 22 on the receiving base is plugged onto the receiving base 18 and the receiving base 18 is preferably completely inserted into the section 22 on the receiving base. Furthermore, the connection housing 14 has a connector device-side section 24 into which the compatible connector device can be plugged in order to connect corresponding coaxial sockets of the connector device to the coaxial connectors 20 .

The connector 10 can in particular be a standard-compliant connector that conforms to a FAKRA standard or a USCAR standard, for example. Furthermore, the plug connector 10 has a form coding 26 formed on the connection housing 14, which ensures that the connection housing 14 has exactly one plug-in option for plugging in the compatible plug device. As in figure 1 shown, the form coding 26 can consist of one or more grooves 26 which extend along the connection direction V on the inside of the connector device-side section 24 of the connection housing 14 .

Furthermore, the connection housing 14 is designed to be fastened in at least two different orientations to the housing body 12 or to the receiving base 18 . In particular, it can Connection housing 14 can be attached to the housing body 12 in different orientations, in which the connection housing 14 is rotated by 90° about a central axis Z, which extends from the center of the receiving base 18 in the direction of the connection direction V. in the in figure 1 In the embodiment shown, the connection housing 14 can be arranged in (precisely) four different orientations on the housing body 12 or on the receiving base 18 . In each of these orientations, the coax connectors 20 are assigned to different coax jacks of the compatible connector device. Furthermore shows figure 2 by way of example, how the connection housing 14 is arranged in a first orientation on the housing body 12 or on the receiving base 18 .

How further in figure 1 shown, the receiving base 18 has a front side 28 pointing in the connection direction V, which is essentially perpendicular to the connection direction V. That is, the normal vector of the front side 28 is essentially parallel to the connection direction V. The front side 28 has an essentially square shape (also compare FIG Figures 3 and 4 ), wherein one narrow side 30 each extends from the four sides of the front side 28 in the direction of the main housing body section 16 counter to the connection direction V in order to connect the front side 28 to the main housing body section 16 . Furthermore, the narrow sides 30 each have a security feature 32, which can be combined with corresponding security features 34 (see figure 4 ) of the connector housing 14 cooperate to secure the connector housing 14 to the housing body 12 and the receptacle socket 18, respectively.

figure 3 12 shows an exploded perspective view of the housing body 12. In order to keep the illustration of the housing body 12 clear, only two of the four coaxial connectors 20 are shown. The housing body 12 consists of a first housing body element 36 and a second housing body element 38, the second housing body element 38 being insertable into the first housing body element 36. Furthermore, the first housing body element 36 has the receiving base 18, in which four passage openings 40 are formed, which extend in the connection direction V extend. The passage openings 40 are such that the coaxial plug connectors 20 are led out of the housing body 12 by means of the passage openings 40 pointing outwards in the connection direction V.

Referring to the Figures 3 , 6 and 7 , the structure of a coaxial connector 20 is explained in more detail. A coaxial connector 20 has an electrically conductive inner contact 42 (see Figures 6 and 7 ) which is essentially flat and elongate. Furthermore, the inner contact 42 is designed to connect a coaxial socket of the compatible plug device to a printed circuit board.

The inner contact 42 can in particular be stamped from a flat starting workpiece. For example, a sheet metal made of an electrically conductive metal can be used as a flat starting workpiece, which has a predetermined material strength or thickness. The material thickness or thickness of the electrically conductive starting workpiece can be between 0.2 mm and 0.4 mm, for example, and preferably about 0.3 mm or exactly 0.3 mm.

The inner contact 42 can be divided into a first contact section 44 and a second contact section 46, the second contact section 46 being angled at a predetermined angle relative to the first contact section 44 (cf figure 3 to figure 6 ). In the exemplary embodiment shown, the first contact section 44 is angled by approximately 90° relative to the second contact section 46 .

As in the Figures 6 and 7 shown, the inner contact 42 in the area of the first contact section 44 has a coaxial socket-side end section 110 which is formed at one end of the inner contact 42 . Furthermore, the end section 110 on the coax socket side is designed to engage in a socket-shaped inner contact of a corresponding coax socket of the compatible plug device.

Furthermore, the inner contact 42 in the region of the second contact section 46 can have a circuit board-side end section 112 which is on the other End of the inner contact 42 is formed. The circuit board side end portion 112 is designed to be electrically connected to the circuit board. In particular, it can be provided that the circuit board-side end section 112 is led out of the housing body 12 so that the circuit board-side end section 112 can be arranged in a passage opening of the circuit board in order to electrically connect the coaxial connector 20 to the circuit board.

Preferably, the end section 110 on the coax socket side and/or the end section 112 on the printed circuit board side can be formed by embossing the inner contact 42 . In particular, the inner contact 42 stamped from the starting workpiece can be subjected to a stamping process, in which the end section 110 on the coax socket side and/or the end section 112 on the printed circuit board side, which after stamping has a substantially rectangular cross section (transverse to the longitudinal direction of the inner contact 42), are shaped in this way be that the cross-section is essentially round and/or oval. Embossing is particularly advantageous since burr formation on the end section 110 on the coax socket side and/or the end section 112 on the printed circuit board side can be prevented.

The end section 110 on the coax socket side and the end section 112 on the printed circuit board side preferably have a substantially round or oval cross section transversely to the longitudinal direction of the inner contact. The cross section/diameter of the end section 110 on the coax socket side can be 0.2 mm to 0.4 mm, for example. Particularly preferably, the cross section of the end section 110 on the coax socket side can have an essentially rectangular basic shape with dimensions of approximately 0.3 mm*0.37 mm, with a radius of approximately 0.1 mm being stamped on all edges. Due to the stamped radius, the cross section of the end section 110 on the coax socket side has the above-mentioned essentially round or oval shape. The diameter of the circuit board-side end section 112 can be 0.2 mm to 0.5 mm, for example. Particularly preferably, the cross section of the printed circuit board-side end section 112 can have an essentially rectangular basic shape with dimensions of approximately 0.3 mm*0.37 mm, with a radius of approximately 0.1 mm being stamped on all edges.

As in figure 7 shown, the inner contact 42 in the region of the first contact section 44 is surrounded at least in sections along the longitudinal direction of the inner contact 42 by a first dielectric insulation element 48, with the end section 110 on the coax socket being exposed, i.e. not being surrounded by the first dielectric insulation element 48. Likewise, the inner contact 42 is surrounded at least in sections by a second dielectric insulation element 50 in the region of the second contact section 46, with the first dielectric insulation element 48 and the second dielectric insulation element 50 being arranged at a distance from one another on the inner contact 42 if the inner contact 42 is not angled. Likewise, the circuit board-side end section 112 is exposed and not surrounded by the second dielectric insulation element 50 . The first dielectric insulation element 48 and the second dielectric insulation element 50 can be connected to the inner contact 42 or arranged on it, in particular using an injection molding process. For example, the inner contact 42 can be arranged on an injection mold which provides recesses for the first dielectric isolation element 48 and/or the second dielectric isolation element 50 . The injection mold or the recesses can be filled with a liquefied dielectric insulating material or a plastic, and the insulating material is then solidified, for example by cooling. Subsequently, the inner contact 42 with the arranged first dielectric insulation element 48 and/or second dielectric insulation element 50 can be removed from the injection mold. The insulation elements produced in this way can also be referred to as insulation bodies, in which the inner contact 42 is arranged at least in sections.

Furthermore, the first dielectric insulation element 48 and the second dielectric insulation element 50 each have a stop surface 52 (see FIG figure 7 ), which limit the angling of the first contact section 44 relative to the second contact section 46 to the predetermined angle, for example approximately 90°. When the predetermined angle is present, the stop surface 52 of the first dielectric isolation element 48 and of the second dielectric isolation element 50 are aligned essentially parallel to one another.

How further in figure 7 shown, the first dielectric insulation element 48 has a sleeve section 56 which at least partially surrounds the inner contact 42 along the connection direction V. The sleeve section 56 adjoins the end section 110 on the coaxial socket side counter to the connection direction V (directly). Contrary to the connection direction V, a housing section 58 of the first dielectric insulation element 48 adjoins (directly) the sleeve section 56 .

The sleeve section 56 has an essentially cylindrical shape, the cylinder axis of the sleeve section 56 lying essentially parallel to the longitudinal direction of the first contact section 44 and essentially coinciding with the end section 110 on the coaxial socket side. The housing section 58 has a rectangular, preferably square, cross-section transversely to the longitudinal direction. Furthermore, the cross-sectional area of the housing section 58 is selected to be larger than the cross-sectional area of the sleeve section 56, so that a stop or shoulder is formed at the transition from the sleeve section 56 to the housing section 58, which is referred to below as the sleeve stop 114.

How out figure 3 As can be seen, the coaxial plug connector 20 has an essentially hollow-cylindrical sleeve 54 which can be pushed onto the sleeve section 56 counter to the connection direction V. The sleeve 54 has a sleeve base 55 which is formed radially outwards and rests against the sleeve stop 114 . Furthermore, the first dielectric insulation element 48 electrically insulates the sleeve 54 from the inner contact 42. Furthermore, the sleeve 54 completely surrounds the end section 110 on the coax socket side along the connection direction V. The sleeve 54 and the end section 110 on the coax socket side are thus designed to be connected to a coax socket of the compatible plug device. Furthermore, it is provided that the sleeve section 56 is arranged between the sleeve 54 and the inner contact 42 .

Furthermore, the second dielectric insulation element 50 has a rectangular, preferably square, transverse to the longitudinal direction of the inner contact 42 cross section.

Referring to the Figures 3 and 4 the assembly of the connector 10 is explained in more detail. How from the in figure 4 The cross-sectional view shown shows that the first housing body has a first insulating element receiving space 60 which adjoins the passage opening 40 of the receiving base 18 counter to the connection direction V. When the plug connector 10 is in the assembled state, the first contact section 44 is arranged at least in sections in the first insulating element receiving space 60 and the passage opening 40 . In particular, the first contact section 44 is inserted with the end section 110 on the coax socket first, in the connection direction V, into the first insulating element receiving space 60 and into the passage opening 40 in order to guide the sleeve 54 out of the housing body 12 to the outside. The passage opening 40 rests flat against the sleeve 54 . The first insulating element receiving space 60 has a rectangular, preferably square, cross-section transversely to the connection direction V, so that the first dielectric insulating element 48 is arranged in a form-fitting manner in the first insulating element receiving space 60 .

Furthermore, the first insulating element receiving space 60 can have a larger cross section than the passage opening 40, so that the transition from the first insulating element receiving space 60 to the passage opening 40 provides a stop 115 or shoulder. In particular, the sleeve stop 114 formed by the sleeve section 56 and the housing section 58 can bear against the stop 115 formed by the passage opening 40 and the first insulating element receiving space 60 when the coax connector 20 or the first contact section 44 of the coax connector 20 is in the connection direction V into the first insulating element receiving space 60 and then through the passage opening 40 . Furthermore, the sleeve base 55 can be arranged between both stops 114/115, as a result of which the sleeve 54 is secured in the housing body 12.

Before or preferably after inserting the coax connector 20 into the first housing body member 36, the second contact portion 46 may be angled with respect to the first contact portion 48 to the predetermined angle.

The second housing body element 38 is then inserted into the first housing body element 36 in such a way that the second contact section 46 and in particular the circuit board-side end section 112 is guided out of the second housing body element 38 and thus out of the housing body 12 or to the outside.

The second housing body element 38 has in particular a second insulating element receiving space 62 which is designed to receive the second dielectric insulating element 48 preferably in a form-fitting manner. The longitudinal direction of the second insulating element receiving space 62 is essentially perpendicular to the connection direction V or corresponds to the longitudinal direction of the second contact section 46. Furthermore, the second insulating element receiving space 62 has a substantially rectangular, preferably square, cross section transverse to the longitudinal direction, so that the second dielectric insulating element 50 can be arranged in a form-fitting manner in the second insulating element receiving space 62 . Furthermore, the second insulating element receiving space 62 provides an opening on the underside 64 of the second housing body element 38 or the housing body 12, through which the second contact section 46 or the end section 112 on the printed circuit board can be guided to the outside. The underside 64 of the second housing body element 38 or of the housing body 12 faces the printed circuit board when the housing body 12 is arranged on the printed circuit board.

Furthermore, the housing section 58 of the first dielectric insulation element 48 has guide elements 59 (see FIG figure 3 ), which support insertion of the first dielectric insulation element 48 into the first housing body element 36 or into the first insulation element receiving space 62 . The guide elements 59 can in particular be designed as projections on the housing section 58 .

The second housing body element 38 has a total of four second insulating element receiving spaces 66, in each of which a second dielectric insulating element 50 can be arranged in a form-fitting manner. Furthermore, the second housing body element 38 has two mutually stepped receiving areas 66/68, each receiving area 66/68 providing two second insulating element receiving spaces 63. Furthermore, the four second insulating member accommodating spaces 63 are separated from each other by walls 70 of the second housing body member 38, respectively. Furthermore, the second insulating element receiving spaces 62 are open towards the underside 64 . Furthermore, the second insulation element receiving spaces 62 are of different lengths in the respective receiving areas 66/68, with second insulating element receiving spaces 62 of the same receiving area 66/68 being of the same length. The length of the second dielectric insulation elements 50 assigned to the respective second insulation element receiving spaces 62 is correspondingly formed.

With reference to figure 5 the bottom of the connector 10 is explained in more detail. The first housing body 12 or the main housing body section 16 has two opposite side walls 72 which extend from the underside 64 of the housing body 12 to an upper side 74 of the housing body 12 . Furthermore, the side walls 72 of the first housing body element 12 are aligned essentially parallel to the connection direction V. FIG. Furthermore, the two sidewalls 72 are spaced apart such that the second housing body member 38 is sandwiched between the two sidewalls 72 of the first housing body member 36 . Two plug contacts 74 are formed on the underside of the two side walls 72, by means of which the housing body 12 can be connected to a printed circuit board. In particular, the plug contacts 74 can be inserted into plug-in holes formed on the landing circuit board and then connected to the circuit board, for example by soldering.

Furthermore, each side wall 72 has a support element 76 with a support surface 78 on the underside 64 . The support element 76 and the support surface 78 are used to support the housing body 12 or the connector 10 on the circuit board, so that the coaxial connector 20, which is preferably used for electrical contact, and the plug contacts 74 do not have to additionally "carry" the weight of the connector 10 or the housing body 12. In addition, the connector 10 thereby has advantages in terms of vibration resistance. Furthermore, the support elements 76 and/or the plug contacts 74 can be used to dissipate heat from the printed circuit board. Likewise, the second housing body element 38 has one or more support elements 76 with corresponding support surfaces 78 on the underside 64 .

Furthermore, deformable securing elements 80 are formed on the underside 64 of the side walls 72 with which the second housing body element 38 can be secured on the first housing body element 36 . By securing it is meant that the second housing body member 38 cannot be separated from the first housing body member 36 . In particular, each side wall 72 has one, preferably precisely one, deformable securing element 80 at an end of the underside 64 lying in the connection direction V and at an end of the underside 64 lying opposite to the connection direction V. The securing element 80 is in each case designed as a projection which extends away from the housing body 12 starting from the underside 64 . Furthermore, the second housing body element 38 has recesses 82 on the underside, into which the securing elements 80 engage when the securing elements 80 are deformed or bent in the direction of the opposite side wall 72 . In particular, the recesses 82 are provided in the corners of the underside 64 of the second housing body element 38, respectively.

With reference to figure 4 the connection housing 14 is explained in more detail below. A partition wall 84 is arranged between the section 22 on the receiving base and the section 24 on the connector device side, which is arranged essentially perpendicularly to the connection direction V. The partition 84 also has four passage openings 86 through which the four coaxial connectors 20 are passed. Furthermore, the section 24 on the connector device side surrounds the four coaxial connectors 20 at least in sections in the connection direction extends from the partition wall 84 toward the connecting direction V. Furthermore, the partition wall 84 and the wall 88 of the connector-device-side section delimit a receiving space into which the compatible connector device is inserted in the direction of the insertion direction E.

Starting from the partition 84, a wall 90 of the section 22 of the connection housing 14 on the receiving base extends counter to the connection direction V. The partition 84 and the wall 90 delimit the section 22 on the receiving base, into which the receiving base 18 is inserted or plugged. Furthermore, the partition wall 84 rests against the front side 28 of the receiving base 18 . The inside of the wall 90 of the section 22 on the receiving base also rests against the narrow sides 30 of the receiving base 18 . As in figure 4 shown, the securing features 34 of the connection housing 14 are formed on the inside of the wall 90 of the socket-side section 22 , which cooperate with the securing features 32 of the receiving socket 18 in order to secure the connection housing 14 to the housing body 12 . In particular, the securing features 34 of the connection housing 14 can be formed as recesses.

The securing features 32 of the receiving base can be designed as projections which are arranged on the outside on the narrow sides 30 . In particular, each of the four narrow sides 30 can have a security feature 32 and the inside of the wall 90 can have corresponding security features 34. Referring to FIG figure 7 the securing feature 32 of the receiving base 18 embodied as a projection has a ramp 92 falling in the connection direction V. Contrary to the connection direction V, the securing feature 32 designed as a projection drops in steps or perpendicularly onto the narrow side 30 . In particular, it can thus be achieved that the connection housing 14 cannot be separated from the housing body 12 without destroying it, since the shape of the securing feature 32 embodied as a projection results in at least damage to the connection housing 14 .

As in figure 4 shown, the front side 28 of the receiving base 18 has two spaced-apart positioning projections 94 which extend starting from the front 28 in the connection direction V. Furthermore, the partition wall 84 of the connection housing 14 has four positioning holes 96 (cf. figure 8 ), About what figure 3 only partially shows three positioning openings 96 due to the sectional drawing. The positioning projections 94 and the positioning openings 96 are arranged such that in each orientation of the connection housing 14 on the housing body 12, one positioning projection 94 engages another positioning opening 96 .

The positioning openings 96 and positioning projections 94 have a substantially triangular shape, preferably an isosceles triangular shape, and more preferably a simultaneous triangular shape. Furthermore, the two positioning projections 94 are arranged opposite one another on the front side 28 of the receiving base 18 . Each positioning projection 94 is centered on an edge 31 which is formed by the front side 28 and a narrow side 30 aligned. In particular, one side of the triangle can be aligned with edge 31 . Also, an isosceles triangle has its base aligned with edge 31 . Further, the four positioning holes 96 are arranged on the partition wall 84 corresponding to the positioning projections 94 . Specifically, the four positioning holes 96 are formed in the partition wall 84 at intervals of 90 degrees. In particular, the four positioning openings 96 can be arranged on the partition wall 84 in such a way that two imaginary connecting lines, which in each case connect two opposite positioning openings 96, have a common point of intersection. With respect to this point of intersection, the four locating holes 96 are formed in the partition 84 at 90° intervals (the point of intersection forms the center of an imaginary circle on which the four locating holes 96 lie). Further, an imaginary straight line which is substantially perpendicular to the partition wall 84 and passes through the common intersection intersects an imaginary connecting line which connects the two positioning projections 94 to each other such that the two positioning projections 94 are equidistant from the imaginary straight line. Furthermore, the imaginary straight line runs through the center point of the front side 28 of the receiving base 18.

As in figure 1 shown, the housing body 12 has recesses 98 on its outer wall, which on the basis of the Figures 9-11 be explained in more detail. The recesses 98 can in particular be in the form of indentations which are formed on the outer wall of the housing body 12 . The housing body 12 or the main housing body section 16 has two opposite main sides 100 on the outside, which are formed by the side walls 72 of the first housing body element 36 and which connect the underside 64 of the housing body 12 to a top side 102 of the housing body 102 opposite the underside. The main sides 100, the top 102 and the bottom 64 extend essentially parallel to the connection direction V. Furthermore, the main sides 100 correspond to the outer sides of the side walls 72 of the first housing body element 36.

A first pair of recesses 104 and a second pair of recesses 106 are formed on both main sides 100 and in both side walls 72, with the first pair of recesses 104 extending from the top 102 in the direction of the underside 64 and the second pair of recesses 106 extending extends from bottom 64 toward top 102 . The longitudinal direction of the recesses 98 is essentially perpendicular to the connection direction V.

The recesses 98 are formed in such a way that the depth a of the first pair of recesses 104 is greater than the width b of the first pair of recesses 106 (cf. figure 10 ), and the depth d of the second pair of recesses 106 is smaller than the width e of the second pair of recesses 106 (cf. figure 11 ). Furthermore, the first pair of recesses 104 and the second pair of recesses 106 on the two main sides 100 are not continuous are opposite to each other (cf. figure 9 ).

In particular, the width b of a recess 98 in the first pair of recesses 104 and the width e of a recess 98 in the second pair of recesses 106 can be 0.04 to 0.08 times, particularly preferably approximately 0.057 times, the total width B of the case body 12 along the connection direction V. The overall width B of the case body can also be viewed as the distance between two notional planes, each of which is perpendicular to the connection direction V, and a first notional plane of the two notional planes at an end of the housing body 12 lying in the connection direction V (without a coaxial connector) and a second notional plane Level of the two fictitious levels at a lying opposite to the connection direction V end of the housing body 12 is located. The overall width B of the housing body 12 can be, for example, in the range between 11 mm and 18 mm and preferably in the range between 13 mm and 16 mm. In a particularly preferred embodiment, the overall width B of the housing body 12 is essentially 15.8 mm and the width b of a recess 98 of the first pair of recesses 104 and the width e of a recess 98 of the second pair of recesses 106 is essentially 0.9 mm.

Furthermore, the depth a of a recess 98 of the first pair of recesses 104 can be 0.10 times to 0.14 times the distance T between the two opposite main sides 100 . In a particularly preferred embodiment, the depth a of a recess 98 of the first pair of recesses can be approximately 0.117 times the distance T of the two opposite main sides 100 .

Furthermore, the depth d of a recess 98 of the second pair of recesses 106 can be 0.045 times to 0.07 times the distance T of the two opposite main sides 100 . In the most preferred embodiment, the depth d of a recess 98 of the second pair of recesses 106 may be approximately 0.055 times the distance T of the two opposing major sides 100 .

For example, the distance T between the two main sides 100 of the housing body 12 can be 10 mm to 13 mm. In the particularly preferred embodiment, the distance T between the two main sides 100 of the housing body 12 is approximately 12 mm, the depth a of a recess 98 of the first pair of recesses 104 is approximately 1.41 mm, and the depth d of a recess 98 of the second pair Recesses 106 about 0.66 mm.

Furthermore, the first pair of recesses 104 and the second pair of recesses 106 are at least 0.15 times and at most 0.25 times of the overall width B of the housing body along the connection direction V from a rear side 108 of the housing body. In the most preferred embodiment, the first pair of recesses 104 and the second pair of recesses 106 may be spaced approximately 3.1 mm from the back 108 of the housing body. The rear 108 is arranged opposite the front 28 and delimits the housing body 12 counter to the connection direction V. Furthermore, the rear side 108 of the housing body 12 can be viewed as the side of the housing body 12 which is essentially perpendicular to the connection direction V and points counter to the connection direction.

Furthermore, the length c of the first pair of recesses 104 can be 0.2 to 0.4 times, preferably 0.3 to 0.38 times, the distance H between the bottom 64 and the top 102 of the housing body 12 correspond. In the most preferred embodiment, the length c of the first pair of recesses 104 may be approximately 0.37 times the distance H between the bottom 64 and top 102 of the housing body 12 .

Furthermore, the length f of the second pair of recesses 106 can correspond to 0.3 to 0.5 times, preferably 0.3 to 0.44 times, the distance H between the bottom 64 and the top 102 of the housing body . In the most preferred embodiment, the length f of the second pair of recesses 106 may be about 0.36 times the distance H between the bottom 64 and the top 102 of the housing body. For example, the distance H between the bottom 64 of the housing body 12 and the top 102 of the housing body 12 can be 10 mm to 14 mm, preferably 11 mm to 13 mm. In the particularly preferred embodiment, the distance H between the bottom 64 of the housing body 12 and the top 102 of the housing body 12 can be approximately 12.05 mm, the length f of the second pair of recesses 106 being approximately 5.7 mm and the length c of the first pair of recesses 104 can be about 4.45 mm.

Furthermore, the distance between the recesses 98 of the first pair of recesses 102 can be 1.3 times to 2.0 times the width b of a recess 98 of the first pair of recesses 102 and the distance between the recesses 98 of the second pair of recesses 106 can be 1.3 times to 2.0 times the width e of a recess 98 of the second pair of recesses 106 .

Furthermore shows figure 11 how the support elements 76 are formed with their support surfaces 78 on the underside 64 of the first housing body element 36 . The support surfaces 78 run essentially parallel to the underside 64 of the housing body 12 or the housing body element 36. Furthermore, the support elements 76 are arranged in the connection direction V between two plug contacts 74. This in figure 11 shown first pair of plug contacts 74, which is arranged in the connection direction V in front of the second pair of plug contacts 74, forms a printed circuit board setting edge. The printed circuit board setting edge corresponds in particular to an imaginary connecting line that connects the first pair of plug contacts 74 to one another. The focus of the connector 10 is chosen so that the focus is opposite to the connection direction V behind the printed circuit board setting edge. As a result, the connector 10 can be placed on the printed circuit board without the connector 10 tilting in relation to the printed circuit board. In particular, the centroid is chosen to lie between two imaginary planes, the first imaginary plane passing through the first pair of pins 74, the second imaginary plane passing through the second pair of pins 74, and the first and second imaginary planes being substantially perpendicular to the Connection direction V stand.

In the Figures 12 to 14 a second embodiment of the housing body 12 or the first housing body element 36 is shown. The second embodiment differs from the embodiment described above in that it only has the first pair of recesses 104 on the respective main sides 100 of the first housing body element 36 . The first pair of recesses 104 each extend from the top 102 of the housing body 36 in the direction of the bottom 64 of the housing body 36.

Furthermore, the first pair of recesses 104, or a first recess 98 thereof, directly adjoins the rear side 108 of the housing body 36 on. The other recess 98 ends in the connection direction V approximately at the level of the transition from the receiving base 18 to the main housing body section 16.

In the second embodiment, the width b of a cutout 98 of the first pair of cutouts 104 may be 0.3 to 0.4 times the total width B of the case body 12 along the connecting direction V (see FIG 14 ). The overall width B of the housing body 12 can be between 11 mm and 14 mm, for example. In a particularly preferred embodiment, the overall width B of the housing body 12 is essentially 12.72 mm and the width b of a recess 98 of the first pair of recesses 104 is essentially 4.1 mm.

Furthermore, the depth a of a recess 98 of the first pair of recesses 104 can be 0.07 times to 0.1 times the distance T between the two opposite main sides 100 . For example, the distance T between the two main sides 100 of the housing body 12 can be 10 mm to 13 mm. In a particularly preferred embodiment, the depth a of a recess 98 of the first pair of recesses can be approximately 0.088 times the distance T of the two opposite main sides 100 . For example, the distance T between the two main sides 100 of the housing body 12 is approximately 11.35 mm and the depth a of a recess 98 of the first pair of recesses 104 is approximately 1 mm.

A method for producing the sleeve 54 of the coaxial connector 20 is described below. The procedure includes the following steps:

• providing a starting workpiece for making the sleeve 54;
• rolling the starting work piece to provide a first shape of the starting work piece having a predetermined material thickness and size,
• forming the rolled starting workpiece having the first shape into a second shape, the second shape being essentially sleeve-shaped and having a first predetermined wall thickness and a first predetermined outside diameter, and
• drawing the starting workpiece having the second shape into a third sleeve shape, the third shape having a second predetermined wall thickness and a second predetermined outside diameter, and the second predetermined wall thickness and second predetermined outside diameter being the wall thickness and outside diameter of a target match sleeve.

The sleeve 54 can preferably be produced in a few steps using the proposed method. Furthermore, with the proposed method, a sleeve 54 can be produced in a simple manner, which has the outside diameter and the wall thickness of a target sleeve. A target sleeve is to be understood as a sleeve which is considered a sample or ideal sleeve and which specifies the shape properties to be achieved for a sleeve 54 to be produced.

Furthermore, in the proposed method, the second predetermined wall thickness is smaller than the first predetermined wall thickness and the second predetermined outer diameter is smaller than the first predetermined outer diameter.

Preferably, the provided starting workpiece can essentially have a flat and rectangular shape. Furthermore, the starting workpiece has a starting area or size and a starting material thickness. By rolling or rolling the starting workpiece, the surface of the starting workpiece can be enlarged and the material thickness of the starting material can be reduced. When the predetermined material thickness and size is reached, the rolling or rolling of the starting workpiece can be terminated. Alternatively, the rolling can be stopped when the predetermined material thickness is reached and the rolled starting workpiece can be cut into workpieces corresponding to the predetermined size, for example with a laser. Advantageously, a large number of intermediate workpieces can be obtained from the starting workpiece, which can be further processed to form a sleeve 54 or sleeves.

Through the step of forming the rolled starting work piece having the first shape, the flat and substantially rectangular starting work piece is first formed into a sleeve shape in which two edges of the starting work piece face each other in an unconnected manner.

• Verbinden der zwei gegenüberliegenden Kanten des Ausgangswerkstücks zu einer Hülsenform, um die zweite Form bereitzustellen.

Preferably, the step of forming the rolled starting workpiece into the second shape can further include:

• Joining the two opposite edges of the starting workpiece into a sleeve shape to provide the second shape.

Preferably, by connecting the two opposite edges, the sleeve shape that is still open in the longitudinal direction can be closed. Preferably, the two opposite edges can be connected by cohesive connection, in particular welding, of the two opposite edges.

• Schneiden des Ausgangswerkstücks, welches die dritte Form aufweist, quer zur Längsrichtung des Ausgangswerkstücks, um eine Anzahl von geschnittenen Hülsen 54 zu erhalten. Vorteilhafterweise kann das die dritte Form aufweisende Ausgangswerkstück durch das Schneiden auf Länge der Soll-Hülse geschnitten werden. Entsprechend weist die hergestellte Hülse die Wandstärke, den Außendurchmesser und die Länge der Soll-Hülse auf.

Preferably, the method can further include:

• Cutting the starting work piece having the third shape transversely to the longitudinal direction of the starting work piece to obtain a number of cut sleeves 54 . Advantageously, the starting workpiece having the third shape can be cut to the length of the desired sleeve by cutting. Accordingly, the sleeve produced has the wall thickness the outer diameter and the length of the target sleeve.

The starting material can preferably have a length which makes it possible to cut a large number of sleeves, which have the length of the desired sleeve, from the starting workpiece having the third shape. Advantageously, the manufacturing process for sleeves 54 can thus be made efficient.

• Prägen des Ausgangswerkstücks welches die dritte Form aufweist, um einen Hülsensockel 55 bereitzustellen (vgl. Fig. 3). Insbesondere können die durch den Schritt des Schneidens erhaltenen Hülsen 54 dem Prägen-Schritt unterzogen werden, um einen Hülsensockel 55 an den Hülsen 54 bereitzustellen. Der Hülsensockel 55 ist an einem Ende der Hülse 54 ausgebildet und ist radial nach außen gerichtet.

Preferably, the method can further include:

• Coining the starting workpiece having the third shape to provide a socket base 55 (cf. 3 ). In particular, the ferrules 54 obtained by the cutting step may be subjected to the embossing step to provide a ferrule base 55 on the ferrules 54 . The sleeve base 55 is formed at one end of the sleeve 54 and faces radially outward.

Furthermore, the second predetermined wall thickness can be in the range from 0.1 mm to 0.5 mm, preferably in the range from 0.2 mm to 0.4 mm, and particularly preferably approximately 0.3 mm.

Furthermore, the second predetermined outer diameter can be between 2.0 mm and 4.0 mm, preferably between 2.2 mm and 3.0 mm, and particularly preferably approximately 2.8 mm.

Furthermore, the length of a sleeve 54 obtained, including the base, can be between 9 mm and 12 mm, preferably between 9.5 mm and 11.5 mm, and particularly preferably around 9.75 mm.

The starting workpiece can preferably consist of an austenitic metal alloy which is preferably non-magnetic. Furthermore, the metal alloy can have a chromium content of at least 8%, in particular at least 18%. The chromium content is preferably about 18.27%. Advantageously, the metal alloy has little or no magnetic conductivity.

The method can preferably have:
Heat treatment of the starting workpiece.
Preferably, the heat treatment can be performed before the starting workpiece is machined, or the finished sleeves 54 can be subjected to the heat treatment.
