Description

[0001] The present invention relates to a connector, a method for manufacturing a connector, and a method for detaching a coaxial contact from a connector.

[0002] Various connectors and corresponding methods for manufacturing connectors are known from the prior art, providing different connections for coupling, for example, with printed circuit boards of electrical devices. For coupling with printed circuit boards, it is particularly known to solder the contacts of the connector to the circuit board.

[0003] It is therefore an object of the present invention to provide a connector and a method for manufacturing a connector which enable improved assembly of a connector and thereby, in particular, provide a connector that is easier to assemble and has a particularly high signal transmission.

[0004] Furthermore, it is an object of the present invention to provide a method for detaching a coaxial contact from a more easily mountable connector, which in particular has a high signal transmission.

[0005] The object of the present invention is therefore in particular to provide an improved connector which is particularly easy to assemble and / or at least partially disassemble.

[0006] These problems are solved by the independent patent claims. Specific embodiments result from the dependent patent claims.

[0007] One aspect of the invention relates to a connector, in particular a circular connector, wherein the connector comprises: a printed circuit board (PCB); a connector body which is fixed to the printed circuit board; an electrically conductive contact device which comprises several contact pins, in particular electrically conductive contact pins, and which is arranged at least partially in the connector body, - wherein the printed circuit board has an opening which is designed such that a coaxial contact or central contact can be mounted through the opening on the contact device.

[0008] In other words, the circuit board has at least one opening which is designed in such a way that at least one coaxial contact or central contact can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0009] Preferably, the circuit board has exactly one opening which is designed such that preferably exactly one coaxial contact or exactly one central contact can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0010] Preferably, the circuit board has exactly one opening which is designed such that two or more coaxial contacts or two or more central contacts can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0011] Preferably, the circuit board has exactly two openings or more than two openings, which are designed such that preferably exactly one coaxial contact or exactly one central contact per opening can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0012] The mounting direction of a central contact or coaxial contact, from the side of the circuit board facing away from the contact device towards the contact device, and in particular substantially axially through the opening of the circuit board, defines a mounting direction for the central contact or coaxial contact. The mounting direction can, in particular, be substantially parallel to an axial direction of the connector, and especially to an axial direction of its connector body and / or its contact device.

[0013] The central contact is designed, but is not limited to, for connection with a coaxial cable and / or a coaxial connector, but can also be connected to conductors of other cables and / or other connectors. The central contact is not limited to a contact that can be mounted geometrically exactly centered between the contact pins. Rather, the central contact is a contact that can be mounted essentially radially within the multiple contact pins. The coaxial contact is, in particular, a contact that is preferably designed exclusively for an electrically conductive connection with a coaxial connector and / or coaxial cable.

[0014] The multiple contact pins can make electrically conductive contact with the circuit board.

[0015] The present connector advantageously allows for the provision of an easily assembled connector. Furthermore, the present connector advantageously enables one or more central contacts or one or more coaxial contacts to be mounted essentially independently of the contact pins on the contact device. This allows the one or more central contacts or the one or more coaxial contacts to be predefined and, in particular, application-specifically designed, in order to predetermine the contact device, and consequently the connector, for specific application needs.

[0016] In particular, the present connector can be easily configured with a predetermined performance characteristic, especially for transmitting electrical signals to the printed circuit board and / or to an electrical device, for example, in the vicinity of the printed circuit board. The performance characteristic includes, in particular, essentially reliable and, especially, interference-free transmission of power levels and / or power frequencies of electrical signals.

[0017] In particular, a combination of the contact pins with at least one central contact or coaxial contact can advantageously provide a mixed predetermined and, in particular, application-specific power characteristic that can be transmitted through the connector.

[0018] For example, the multiple contact pins can be configured to transmit a comparatively low power and / or power frequency of an electrical signal. Alternatively or additionally, at least one central contact or coaxial contact can be configured to transmit a comparatively high power and / or power frequency of an electrical signal. In particular, one of the multiple contact pins can be configured to transmit an electrical signal with a frequency in the range of approximately 0 kHz to approximately 10,000,000 kHz. A central contact, and in particular a coaxial contact, can be configured to transmit an electrical signal with a frequency in the range of approximately 0 kHz to approximately 50,000,000 kHz, in particular in the range of approximately 0 kHz to approximately 10 GHz.

[0019] A central contact, and in particular a coaxial contact, can be designed to transmit high-frequency, broadband signals in the frequency range from a few kHz to a few GHz. These can be high-frequency broadcast signals, radar signals, network transmissions, audio signals, and / or simply measurement signals, for example, in a test laboratory. The central contact or coaxial contact can, in particular, comprise an inner conductor and an outer conductor, or have a first conductor element for an inner conductor and a second conductor element for an outer conductor of a coaxial cable, especially for transmitting high-frequency unbalanced signals. The outer conductor typically carries the reference potential, namely ground, while the inner conductor carries the signal voltage or, in the case of remote power supply, the supply voltage. Furthermore, the central contact or coaxial contact can be used, for example, to generate high-power pulses in radar technology.No signals are transmitted in this process; instead, the central contact or coaxial contact acts as a high-voltage source with a precisely defined internal resistance, releasing its entire stored charge after a defined time. Furthermore, the central contact or coaxial contact can be configured for the electrical transmission of digital stereo or multi-channel audio signals between different devices.

[0020] The present connector can, in particular, be an interface for transmitting one of the electrical signals mentioned herein to an electrical device. In exemplary embodiments, the present connector can, in particular, be an interface for the direct transmission of electrical signals to the printed circuit board via the contact pins, and for the direct transmission of electrical signals to an electrical device or its cable via one or more central contacts or coaxial contacts.

[0021] The opening on the circuit board further advantageously enables a space-saving arrangement of the connector, which can be formed by mounting one or more predetermined central contacts or coaxial contacts with a predetermined and, in particular, application-specific performance characteristic.

[0022] Furthermore, the opening on the circuit board advantageously allows a high-power or high-frequency electrical signal to be tapped directly, or even at all, from the central contact or coaxial contact, thus minimizing damage to the circuit board. For example, the central contact or coaxial contact can be electrically connected via a separate, electrically conductive connection or via an electrical device that may be connected to the circuit board, i.e., may encompass the circuit board, but need not be. This also makes the shielding of the circuit board advantageously simple.

[0023] Thus, it is advantageous to be able to set a predetermined transferable power characteristic, or in other words, to provide it, while further advantageously ensuring a long service life of the printed circuit board.

[0024] The opening in the printed circuit board can be designed, in particular, as a through-hole in the printed circuit board, specifically as a through-hole extending through one of the board's thickness directions. The thickness direction of the printed circuit board corresponds, in particular, to the direction of least thickness. In other words, the thickness direction of the printed circuit board corresponds, in particular, to the direction in which a person skilled in the art would typically describe the printed circuit board as flat or thin.

[0025] The through-hole is radially bounded, in particular by the printed circuit board. This allows the central contact or coaxial contact to be advantageously guided through the printed circuit board during assembly. In the assembled state of the at least one central contact or coaxial contact, the opening and the central contact or coaxial contact cannot touch each other. In other words, the opening or through-hole can have a larger inner diameter than the outer diameter of the at least one central contact or coaxial contact that can be mounted on the contact device. Furthermore, the opening or through-hole can have a larger inner diameter than the outer diameter of the contact pins, specifically each contact pin of the contact device.

[0026] The at least one central contact or coaxial contact is therefore essentially decoupled from direct force transmission between the at least one central contact or coaxial contact and the printed circuit board. This advantageously improves both the service life of the printed circuit board and the service life of the at least one central contact or coaxial contact.

[0027] The connector body can be designed in particular to be able to couple with a complementary circular connector, and, for example, to at least partially incorporate and / or be surrounded by a circular connector body of the complementary circular connector.

[0028] The connector body can, for example, have a substantially tubular, particularly cylindrical, or in other words, hollow cylindrical shape. The connector body can, in particular, have a greater extension in an axial direction, which can be substantially parallel to a mating direction of the connector, than the contact device. In other words, the connector body fixed to the printed circuit board can, in particular, have a greater extension away from the printed circuit board than the contact device arranged at least partially within the connector body.

[0029] This allows the contact device to be advantageously protected within the connector body, and in particular, protected from touch within the connector body.

[0030] The present connector allows the circuit board, connector body, and contact device to be advantageously pre-assembled together. This simplifies the subsequent assembly of one or more of the central contacts or coaxial contacts to create a connector with an application-specific power transmission characteristic.

[0031] The contact device can, in particular, form a socket for electrically conductive contact with a plug complementary to the socket. Furthermore, the contact device can, in particular, form a plug for electrically conductive contact with a socket complementary to the plug.

[0032] An exemplary embodiment of the contact device as a socket results in a different insertion direction, in particular a substantially opposite insertion direction, compared to an embodiment of the contact device as a plug. If the contact device forms a socket, the insertion direction points, for example, towards the contact pins that the contact device comprises, and thus, in particular, towards the circuit board. If the contact device forms a plug, the insertion direction points, for example, away from the contact pins that the contact device comprises, and furthermore, in particular, away from the circuit board.

[0033] The present example assumes a contact device in the form of a socket, although the contact device is not limited to this. Therefore, if areas or sides are shown in relation to the insertion direction, these apply to an embodiment of the contact device as a plug, in particular to the opposite area or side with respect to the insertion direction.

[0034] In preferred embodiments of the connector, the contact device can have a contact body on which the contact pins are arranged, in particular in a form-fitting and / or friction-fitting manner, and the central contact or coaxial contact can be detachably connected to the contact body, in particular in a way that is damage-free or non-destructive.

[0035] The contact body can be designed in particular to be couplingable with a complementary circular connector, and, for example, to at least partially incorporate and / or be surrounded by a connector body and / or contact body of the complementary circular connector.

[0036] One or more of the contact pins can preferably be detachably arranged on the contact body by a form-fit and / or friction fit. One or more of the contact pins can, for example, have one or more fixing projections, particularly in a radial direction, to engage with a first contact point of the contact body by a form-fit and / or friction fit. The first contact point, or in other words, the contact point for receiving a contact pin, particularly a single contact pin, can in particular have one or more projections and / or recesses that can be engaged by a form-fit connection, for the form-fit arrangement of a contact pin on or in it.Additionally or alternatively, the first contact point can have a cross-section which forms a transition fit or an interference fit with a cross-section of a contact pin, in particular with a cross-section of a contact pin in an area where a fixing projection of the contact pin is arranged.

[0037] The contact body can, in particular, have a plurality of first contact surfaces corresponding to the plurality of contact pins. Alternatively, the contact body can have a plurality of first contact surfaces exceeding the plurality of contact pins. This allows the contact pins to be advantageously fixed to the contact body, and in particular, fixed to the contact body by means of a pre-assembly upstream of the arrangement of the contact device on the connector body. Furthermore, the power characteristic that can be transmitted by means of the plurality or number of contact pins is advantageously adjustable.

[0038] The contact body can be designed in a ring-shaped cross-section, particularly in a cross-section substantially transverse to the axial direction, especially such that the first contact surfaces are arranged ring-shaped along the circumferential direction on the contact body. For example, the first contact surfaces can be arranged substantially ring-shaped, particularly substantially circumferentially, around one or more second contact surfaces of the contact body, each of which is designed to receive a central contact or coaxial contact.

[0039] The connector can be advantageously manufactured modularly, whereby the number of multiple contact pins is independent of the number of initial contacts, apart from the limitation imposed by the maximum number of initial contacts. This also makes the connector advantageously resource-efficient to manufacture.

[0040] A first contact point of one or more first contacts can, in particular, have a continuous receiving opening, wherein the continuous receiving opening can, in particular, be stepped. The receiving opening of the first contact point can, in particular, be stepped such that the diameter of the receiving opening at an end facing the circuit board is larger than the diameter of the receiving opening at an end facing away from the circuit board. Furthermore, the receiving opening can, in particular, have an insertion chamfer at one or both ends. The step of the receiving opening can, in particular, be arranged on a side of the receiving opening facing away from the circuit board.

[0041] This makes it advantageously easy to insert the contact pin into the first contact receptacle or its receiving opening. The step advantageously provides a stop beforehand, ensuring a predetermined position of the contact pin within the first contact receptacle. Furthermore, the step enables precise guidance of a complementary conductor element to or against the contact pin for electrically conductive contact.

[0042] The contact pin can have insulation, particularly on an outer circumferential side, especially Teflon insulation. Alternatively or additionally, the central contact or coaxial contact can have insulation, particularly on an outer circumferential side, especially Teflon insulation.

[0043] The insulation provides advantageous electrical protection for the contact pin and / or the central contact or coaxial contact. Furthermore, the Teflon insulation provides advantageous temperature resistance for the contact pin and / or the central contact or coaxial contact.

[0044] The contact body can, in particular, be an insulator or comprise an insulator. The contact device can therefore, in particular, be designed to be electrically conductive by means of the contact pins and the central contact or coaxial contact. The contact pins and the central contact or coaxial contact can therefore, in particular, be arranged on the contact body in the insertion direction, or in other words, in particular from a side of the contact device facing away from the circuit board, so that they can be made accessible for electrically conductive contact.

[0045] The contact body can be designed in particular to spatially separate the contact pins from each other, and in particular from the at least one central contact or coaxial contact, especially in the circumferential direction and / or in the radial direction, in particular by means of an insulating section.

[0046] This allows the electrically conductive elements of the contact device to be advantageously protected, ensuring good contactability and signal transmission.

[0047] Another aspect of the present invention relates to a connector, in particular a circular connector, wherein the connector comprises: a printed circuit board (PCB); a connector body which is fixed to the printed circuit board; an electrically conductive contactable contact device (30) which comprises several contact pins and which is arranged at least partially in the connector body, - wherein at least one central contact or coaxial contact is arranged and in particular fixed to the contact device, and - wherein the at least one central contact or coaxial contact extends through an opening in the printed circuit board.

[0048] In other words, in particular at least one central contact or coaxial contact can be arranged and, in particular, fixed on the contact device, wherein the at least one central contact or coaxial contact extends through an opening in the printed circuit board.

[0049] Preferably, the printed circuit board has exactly one opening, wherein the at least one central contact or coaxial contact extends through the exactly one opening in the printed circuit board.

[0050] Preferably, exactly one central contact or coaxial contact extends through exactly one opening in the printed circuit board.

[0051] Preferably the printed circuit board has exactly two or more than two openings, with exactly one central contact or coaxial contact extending through each opening of the printed circuit board.

[0052] Preferably, two or more than two central contacts or coaxial contacts extend through each opening in the printed circuit board.

[0053] The at least one central contact or coaxial contact extending through the opening on the printed circuit board (PCB) advantageously allows a high-power or high-frequency electrical signal to be tapped directly at the central contact or coaxial contact, rather than being sent directly or at all via the PCB, thus minimizing damage to the PCB. For example, the central contact or coaxial contact can be electrically connected via a separate electrically conductive connection or via an electrical device that may be connected to the PCB, i.e., may encompass the PCB, but need not be.

[0054] This makes it advantageous to set a predetermined transmissible power characteristic, or in other words, to provide it, while further advantageously ensuring a long service life of the printed circuit board, especially for transmitting electrical signals which have a less stressful power characteristic for the printed circuit board.

[0055] Exemplary, preferred and alternative embodiments of the aspect relating to the connector, wherein at least one coaxial contact is arranged on the contact device, and their effects, may in particular correspond to those explained in relation to the aspect relating to the connector, wherein a coaxial contact can be mounted on the contact device, and vice versa.

[0056] The connector of the further aspect relates in particular to a connector of the aspect previously explained, in a state in which at least one central contact or coaxial contact is mounted on the contact device, in particular mounted on the contact device in such a way that it extends section by section through the opening of the printed circuit board.

[0057] The at least one central contact or coaxial contact can, in the assembled state of the connector, be attached in particular to the contact device, or in other words, connected to the contact device.

[0058] The at least one central contact or coaxial contact can, in the assembled state of the connector, be attached to the contact device, in particular by a first section or a first end, or in other words, connected to the contact device. Furthermore, in the assembled state of the connector, the at least one central contact or coaxial contact can, in particular, protrude from or out of the opening of the circuit board by a second section or a second end, which is arranged opposite the first section or end relative to the circuit board.

[0059] This means that at least one central contact or coaxial contact is advantageously reliably connected to the contact device, and at the same time advantageously easily electrically conductive contactable at its end protruding through the opening or at its section protruding from the opening, for example with an electronic device, so that the circuit board is advantageously protected and advantageously designed for durability.

[0060] In preferred embodiments of the connector, in particular the connector according to the further aspect, the contact device can have a contact body on which the contact pins are arranged, in particular in a form-fitting and / or friction-fitting manner, and / or the at least one central contact or coaxial contact can be detachably connected to the contact body, in particular in a way that is detachable without damage or destruction.

[0061] This makes it advantageously easy to connect at least one central contact or coaxial contact to the contact body.

[0062] In addition, an application-specific central contact or coaxial contact can be connected to the contact body.

[0063] This makes it advantageous to provide a connector with a predetermined and, in particular, application-specific transmissible power characteristic, especially in a resource-saving manner.

[0064] Several terms will be used repeatedly below, and their understanding will be facilitated by the following definitions.

[0065] The assembled state of the connector describes in particular a state in which the at least one central contact or the at least one coaxial contact is arranged on the contact device of the connector and is in particular attached to it, for example detachably, in particular detachably without damage or non-destructively.

[0066] The unassembled state of the connector, also described herein as the unmounted state, describes in particular a state in which the at least one central contact or the at least one coaxial contact is not arranged on the contact device, and in particular is not attached. In the unmounted state, the at least one central contact or the at least one coaxial contact cannot yet extend, at least partially, through the opening in the circuit board.

[0067] Connectors or circular connectors: The circular connector in this case essentially represents a connector which, at least in sections, has a substantially cylindrical or tubular shape or contour, but is not limited to this, and can also have any contour in cross-section relative to an axial direction or insertion direction of the circular connector, in particular be polygonal or be partially round and angular. The circular connector can, in particular, provide a screw connection and / or a push-push connection and / or a push-pull connection to a complementary circular connector by means of its connector body, or form a connection with a complementary circular connector.

[0068] Axial direction: The axial direction describes, in particular, the direction in which the connector, and especially the circular connector, has its greatest extent. Furthermore, the axial direction can essentially lie in the direction along which the contact device, and especially the contact pins and / or the at least one central contact or coaxial contact, are designed to be electrically conductive. Thus, the axial direction can, in particular, be essentially parallel to, or essentially correspond to, a mating direction of the connector or circular connector. The mating direction represents the direction in which the connector, and especially the circular connector, is mated relative to a complementary connector or...Circular connector is moved to provide an electrically conductive and / or data-transmitting contact between the connector, and in particular the circular connector, and a complementary connector or circular connector.

[0069] Circumferential direction: The circumferential direction is a direction that is essentially perpendicular to the axial direction or mating direction. The circumferential direction can, in particular, essentially correspond to a direction along a circumference of the connector, and especially a circular connector, or to a direction along an outer contour of the connector or circular connector in a cross-section of the connector or circular connector, or to a direction along the outer contour of an element of the connector or circular connector in a cross-section of the connector or circular connector, wherein the cross-section is essentially perpendicular to the axial direction or mating direction of the connector or circular connector. The circumferential direction can, in particular, correspond to a direction tangent to a circumference of the connector or circular connector or to an element of the connector or circular connector.The circumferential direction corresponds to a circular connector, in particular to a direction along a tangent to a contour of the connector or circular connector, or of an element of the connector or circular connector in a cross-section. In other words, the circumferential direction can be similar to the circumferential direction of a cylinder, and the present connector, and in particular the circular connector, is not limited to a strictly cylindrical contour.

[0070] Radial direction: The radial direction is a direction that is essentially perpendicular to the axial direction or insertion direction and / or the circumferential direction. The radial direction can point, in particular, from an axis of the connector, and especially of a circular connector, towards an outer contour or surface, specifically towards an outer contour or surface of the connector or circular connector, or of an element of the connector or circular connector.

[0071] The axial direction or insertion direction, together with the circumferential direction and the radial direction, can in particular form a right-handed system, especially a cylindrical coordinate system.

[0072] Insertion direction: The insertion direction describes in particular a direction in which the connector and especially its contact device or the contact pins and / or the at least one central contact or coaxial contact can be moved or are to be moved relative to a complementary connector in order to be brought into a coupled state and in particular an electrically conductive contacting state with a complementary connector.

[0073] The insertion direction of the connector, and in particular the circular connector, can be essentially parallel to the insertion direction of the complementary connector, and in particular the circular connector. The insertion direction of the connector can additionally or alternatively be essentially opposite to the insertion direction of the complementary connector.

[0074] It is understood that the insertion direction during assembly by an operator and / or an operating unit may deviate from the insertion direction defined here, as long as it results in a coupling, in particular a damage-free electrically conductive coupling, of the connector with the complementary connector.

[0075] The insertion direction can essentially be parallel to the axial direction.

[0076] The protection mentioned herein can, in particular, be contact protection. Contact protection can specifically include protection against contact by an operator, for example, against contact with the operator's finger. Alternatively or additionally, contact protection can include protection against contact with objects of a predetermined size, for example, against contact with objects whose smallest dimension exceeds approximately 20 mm, in particular approximately 17 mm. The protection can, for example, be provided by a predetermined definition of the inner diameter of the connector body at one end of the connector body facing away from the circuit board.

[0077] When a direction or angle is indicated with the addition of "essentially" or "approximately" or "about", this addition is intended to refer in particular to a deviation from the direction or angle in question in the range of 0° to 5°.

[0078] If a spatial measure, spatial ratio or other ratio is given with the addition of "essentially" or "approximately" or "about", this addition is intended to indicate, in particular, a deviation from the measure or ratio in question in the range of 0% to 10%.

[0079] The embodiments described below relate in particular to the connectors according to both aspects described above.

[0080] In preferred embodiments of the connector, at least some of the multiple contact pins, in particular each of the multiple contact pins, can be connected to the circuit board, in particular directly connected.

[0081] One or more of the multiple contact pins, in particular each of the multiple contact pins, can be connected to the circuit board, in particular by material bonding and / or friction bonding, in particular directly connected.

[0082] In exemplary embodiments, one or more of the multiple contact pins can be soldered to the circuit board, for example by means of reflow soldering.

[0083] This allows the contact pins to be advantageously electrically conductive and connected to the circuit board. Furthermore, the contact pins, and in particular the contact device on which the contact pins are arranged, are advantageously firmly connected to the circuit board. This, in turn, also allows the at least one central contact or coaxial contact to be advantageously held firmly on the circuit board by means of the contact device.

[0084] In preferred embodiments of the connector, the contact pins of the contact device can be arranged circumferentially around the opening of the circuit board, i.e., in particular around the through-hole of the circuit board.

[0085] In exemplary embodiments, at least three contact pins can be arranged on the contact device and, in particular, connected to the printed circuit board. For example, approximately 3 to approximately 20 contact pins, more specifically approximately 6 to approximately 16 contact pins, and preferably approximately 8 to approximately 12 contact pins, can be arranged on the contact device and, in particular, connected to the printed circuit board. The contact pins can, in particular, be arranged along a single predetermined radius or along several predetermined radii in the circumferential direction around the opening of the printed circuit board.

[0086] This allows a contact device, essentially designed for a circular connector, to be advantageously and uniformly held on the circuit board while simultaneously ensuring a predetermined transmissible power characteristic, particularly a low-frequency power characteristic. This, in turn, also allows the at least one central contact or coaxial contact to be advantageously and uniformly held or supported on the circuit board by means of the contact device.

[0087] In preferred embodiments of the connector, at least one opening can be arranged centrally relative to the multiple contact pins.

[0088] In other words, at least one opening (radial) can be arranged within the multiple contact pins, for example in a top view of the connector, or when viewed in a section essentially perpendicular to an axial direction of extension or axial direction of the coaxial contact and / or the contact pins.

[0089] This allows at least one coaxial contact to be held advantageously and stably, and to be supported stably and symmetrically for contacting and / or disconnecting.

[0090] In preferred embodiments of the connector, the at least one central contact or coaxial contact can be fixed or secured to a contact body of the contact device by means of a releasable clip that is at least partially C-shaped in cross-section, and preferably the clip that is at least partially C-shaped in cross-section can have at least one spring hook, in particular several spring hooks that are essentially diametrically opposed to each other, for example two spring hooks that are essentially diametrically opposed to each other.

[0091] The cross-section of the clip, in which the clip is formed at least partially in a substantially C-shape, is in particular substantially transverse to the axial direction and / or to the insertion direction of the at least one central contact or coaxial contact in a state of the at least one central contact or coaxial contact mounted on the contact device.

[0092] The C-shaped clip can be pre-mounted on at least one central contact or coaxial contact. In particular, one clip with a substantially C-shaped cross-section can be provided for each central contact or coaxial contact.

[0093] In the assembled state of the at least one central contact or coaxial contact, the clip extends in particular between an outer circumferential surface of the at least one central contact or coaxial contact and an inner circumferential surface of the contact body, in particular an inner circumferential surface of a second contact receptacle of the contact body, which is designed to receive the at least one central contact or coaxial contact at least section by section.

[0094] The second contact point is, in particular, a contact point separate from the first contact point, i.e., a contact point that is essentially radially spaced from the first contact point. Alternatively or additionally, the second contact point can be spaced circumferentially and, in particular, offset circumferentially from one or more first contact points.

[0095] The one or more spring hooks spread out, in particular essentially radially, i.e. radially from a clip body of the clip, which is designed to essentially conform to the outer circumferential surface of the central contact or coaxial contact, in particular to conform to a pre-tensioned position.

[0096] The spring hook(s) are specifically designed to exhibit an increasing, essentially radial, spreading in the opposite direction to the mounting direction of the central contact or coaxial contact in order to attach the central contact or coaxial contact to the contact device.

[0097] Several spring hooks advantageously enable the central contact or coaxial contact to be supported in the receptacle in an essentially central, or in other words radially centered, manner.

[0098] The second contact point has, in particular, a fixing projection on an inner circumferential side against which one or more of the spring hooks can abut with their radially splayed ends. The fixing projection has, in particular, an end face that is essentially perpendicular to the axial direction and / or the insertion direction, against which the spring hooks can be supported or against which they can abut, especially when the central contact or coaxial contact is moved against the axial direction and / or the mounting direction and / or the insertion direction, i.e., especially when pulled through the opening of the circuit board.

[0099] The clip can, in particular, be a C-shaped clip, wherein one end of the clip is separated from the other end of the clip in the circumferential direction, and in particular is spaced apart from the other end in the circumferential direction. In other words, the ends of the clip are, in particular, substantially separated or spaced apart from each other in the circumferential direction.

[0100] The circumferential spacing of the clip ends can preferably be smaller in a state where the clip is not arranged on the central or coaxial contact than in a state where the clip is arranged on the central or coaxial contact. In other words, when the clip is not arranged on the central or coaxial contact, it can have an inner diameter that is smaller than the outer diameter of the central or coaxial contact on which the clip is to be arranged to fix the contact or coaxial contact to the contact device.

[0101] This makes it advantageous to arrange the clip with a preload on the central contact or coaxial contact, and in particular to pre-assemble it safely.

[0102] Furthermore, the clip can be arranged in the insertion direction and / or against the insertion direction on the central contact or coaxial contact, for example by means of a sliding motion essentially parallel to the axial direction and / or to the insertion direction.

[0103] The clip can be arranged on the central contact or coaxial contact, in particular, in a state where the central contact or coaxial contact is at least partially located within the contact device. Alternatively, the clip can be arranged on the central contact or coaxial contact in a state where the central contact or coaxial contact is not at least partially located within the contact device, for example, as a pre-assembly, before the central contact or coaxial contact is positioned or fixed to the contact device, and in particular before the central contact or coaxial contact is guided through the opening in the printed circuit board.

[0104] For example, the clip can be pre-mounted on a clip receptacle, or in other words, a clip receptacle area of ​​the central contact or coaxial contact, and in particular, pre-mounted in a form-fitting manner. The central contact or coaxial contact, especially together with the clip, can then be arranged on the contact device or its contact body, and in particular on the second contact receptacle of the contact body, and can be fixed in place, especially by means of the clip. When arranging the central contact or coaxial contact, one or more spring hooks can be designed to slide off a stop projection of the second receptacle, in particular by means of a return deflection radially inwards.

[0105] After passing the stop projection, the spring hooks are specifically designed to deflect radially outwards in a retracting manner, and to form a radial engagement and / or end-face stop with the fixing projection when the central contact or coaxial contact moves against the axial direction.

[0106] The stop projection and the fixing projection can, in particular, be integrally formed, or in other words, can be formed without separation in the axial direction at the second receptacle. The stop projection can therefore, in particular, be a section of the fixing projection facing the circuit board. In other words, the fixing projection can, in particular, be a section of the stop projection facing away from the circuit board.

[0107] The central contact or coaxial contact can be fixed to the second contact receptacle, particularly in a form-fitting manner, by means of the clip.

[0108] In further exemplary embodiments, the clip can be pre-mounted on the contact device, i.e., in particular in the second contact receptacle of the contact device, or can already be pre-mounted.

[0109] The clip can, in particular, be a bent part from which the spring hooks are integrally formed, for example, by section-by-section cutting the spring hooks out of the bent part, and especially by bending the spring hooks radially outwards. The clip can, in particular, be a C-shaped bent plate. The spring hooks can, for example, be formed on the clip by laser cutting and / or punching, and in particular by a further step of bending or pressing the spring hooks radially outwards to create a spreading effect.

[0110] This makes the clip advantageously easy to manufacture, and at the same time advantageously designed to form both a passive and reliable fixation for the central contact or coaxial contact on the contact device.

[0111] Due to the spring hooks, which spread out increasingly (radially) in particular against the axial direction and / or against the mounting direction, and which in particular support themselves against or strike a fixing projection of the second receptacle, one or more spring hooks are subjected to increasing bending stress when the central contact or coaxial contact moves against the axial direction and / or against the mounting direction.

[0112] This advantageously provides a passive fixing force that increases with the movement of the central or coaxial contact against the axial direction and / or the mounting direction, and which can only be overcome by damaging or destroying the clip. This, of course, only applies if no prior step of releasing the assembly or fixing the central or coaxial contact from the second contact point has taken place, for example, by means of a tool or disassembly tool.

[0113] The at least one central contact or coaxial contact cannot be fixed to the contact device without damage or destruction using the clip and without a disassembly tool that deflects the clip radially inwards. Furthermore, the at least one central contact or coaxial contact cannot be fixed to the contact device without damage and, in particular, without destruction using the clip, and especially with the aid of a disassembly tool that deflects the clip radially inwards.

[0114] In preferred embodiments of the connector, the connector body can be electrically conductive.

[0115] In particular, the connector body can be electrically conductive and connected to the circuit board, for example by soldering.

[0116] Additionally or alternatively, the connector body can be fixed to the printed circuit board by means of self-retaining, in particular radially elastic, self-retaining fixing pins, and in particular be electrically conductively connected. The fixing pins can in particular be designed to be solderable, in particular reflow-solderable.

[0117] This advantageously provides reliable shielding, which in particular shields the contact pins and / or at least one central contact or coaxial contact, thereby advantageously ensuring high transmission quality.

[0118] In preferred embodiments of the connector, the at least one central contact or coaxial contact can have a diameter that is larger than the diameter of one of the contact pins.

[0119] The diameter refers in particular to a diameter, especially an outer diameter, measured in cross-section substantially transverse to the axial direction or transverse to the axial extent of the respective contact pin or coaxial contact.

[0120] This allows the central contact or coaxial contact to advantageously provide a larger cross-section for transmitting electrical signals or for accommodating electrically transmitting conductors. Furthermore, the central contact or coaxial contact has, in particular, a cross-section for passing through conductors separated from each other by insulation and / or shielding. This makes the central contact advantageously designed, compared to the contact pin, to transmit a comparatively higher signal frequency of electrical signals essentially without interference.

[0121] The connector can therefore advantageously be provided with a mixed predetermined and, in particular, application-specific power characteristic that can be transmitted through the connector. Furthermore, excessive stress on the printed circuit board can be avoided, especially by guiding the central contact or coaxial contact through the opening, particularly by ensuring that the central contact or coaxial contact is not directly connected to the printed circuit board, but rather directly to an electrical device or a cable of an electrical device, which may be located in the vicinity of the printed circuit board, but need not be.

[0122] The contact pins of the multiple contact pins can, in particular, have essentially the same diameter. The contact pins of the multiple contact pins can, in particular, be essentially identical in design to each other.

[0123] This allows a predetermined part of the power characteristics that can be transmitted through the connector to be ensured in a simple and cost-effective manner.

[0124] In preferred embodiments of the connector, at least two central contacts or coaxial contacts can be arranged on the contact device, wherein preferably the at least two central contacts or coaxial contacts can extend through a single opening of the circuit board, or each central contact or coaxial contact of the at least two central contacts or coaxial contacts can extend through one opening of the circuit board.

[0125] Separate openings in the circuit board advantageously allow for precise guidance during the assembly of central or coaxial contacts. A single opening in the circuit board is also advantageously easy to manufacture.

[0126] The multiple central contacts or coaxial contacts, for example two, three, four, five, six, or more, advantageously allow a predetermined and, in particular, application-specific performance characteristic to be set, which can be transmitted through the connector.

[0127] Another aspect of the present invention relates to a method for manufacturing a connector, in particular a circular connector, especially a connector as described herein, comprising the steps, in particular in this order: Providing a printed circuit board with at least one through-hole, or in other words, at least one opening; providing a connector body, in particular a substantially cylindrical connector body; fixing the connector body to the printed circuit board, in particular such that the through-hole is accessible through the connector body; providing an electrically conductive contact device comprising several contact pins; arranging the contact device on the connector body such that at least one coaxial contact or central contact can be mounted through the at least one through-hole on the contact device.

[0128] Preferably, the circuit board has exactly one through-hole, i.e., exactly one opening, which is designed such that preferably exactly one coaxial contact or exactly one central contact can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0129] Preferably, the circuit board has exactly one through-hole, i.e., exactly one opening, which is designed such that two or more coaxial contacts or two or more central contacts can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0130] Preferably, the circuit board has exactly two through holes or more than two through holes, i.e., exactly two openings or more than two openings, which are designed such that preferably exactly one coaxial contact or exactly one central contact per opening can be mounted on the contact device, in particular from a side of the circuit board facing away from the contact device.

[0131] The arrangement of the contact device on the connector body can in particular include a positive-locking and / or friction-locking arrangement of the contact device on the connector body.

[0132] Furthermore, the arrangement of the contact device on the connector body can in particular include connecting the contact pins to the circuit board, in particular a material-bonded connection of the contact pins to the circuit board, for example by soldering, in particular by reflow soldering.

[0133] The present method for manufacturing the connector allows the connector to be advantageously provided in a simple manner with a predetermined and, in particular, application-specific transmissible power characteristic for the transmission of electrical signals.

[0134] Exemplary, preferred and alternative embodiments of the aspect relating to the method for manufacturing the connector, as well as their effects, may in particular correspond to those explained in relation to the aspects relating to the connector, and vice versa.

[0135] In preferred embodiments of the method, the method may further comprise, in particular after arranging the contact device on the connector body: Fixing the at least one central contact or coaxial contact with, or in other words, on the contact device, in particular with or on a contact body of the contact device.

[0136] In other words: Mounting the at least one central contact or coaxial contact with or – in other words – on the contact device, in particular with or on a contact body of the contact device. Fixing and mounting can therefore be used synonymously.

[0137] Fixing the coaxial contact to or on the contact body of the contact device can include, for example: Attaching a clip to an outer circumferential side of the central contact or coaxial contact, in particular to a clip receptacle of the central contact or coaxial contact; and guiding the central contact or coaxial contact with the clip through the through-hole of the printed circuit board until a predetermined fixing position is reached on or in the contact device or on or in the contact body of the contact device or on or in the second contact receptacle of the contact body; or alternatively include: Guiding the central contact or coaxial contact through the through-hole of the printed circuit board until a predetermined fixing position is reached on or in the contact device or on or in the contact body of the contact device or on or in the second contact receptacle of the contact body; and attaching a clip to an outer circumferential side of the central contact or coaxial contact, in particular on a clip receptacle of the central contact or coaxial contact; in particular by guiding the clip in the insertion direction into the contact device and onto the central contact or coaxial contact.

[0138] The predetermined fixing position is not limited to a single geometric position, but can in particular comprise a region, especially a region substantially limited in the axial direction and / or assembly direction and / or insertion direction, along which the at least one central contact or coaxial contact on or in the contact device is movable. The fixing position is in particular a position which is limited in the fixed state of the central contact or coaxial contact, and which in a released state of the central contact or coaxial contact is only partially limited, for example, limited on one side in the axial direction, or is not limited, for example, not limited on both sides in the axial direction.

[0139] The fixing position can be limited, in particular essentially in the assembly direction and / or in the axial direction, i.e., in particular essentially against the insertion direction, by a stop between a mounting projection of the central contact or coaxial contact and a stop projection of the contact body.

[0140] If the clip is arranged on a predetermined clip receptacle of the central contact or coaxial contact, the fixing position can be limited, in particular essentially against the mounting direction and / or axial direction, i.e., in particular essentially in the insertion direction, by a stop between the clip and a fixing projection of the contact body.

[0141] This makes it advantageously possible to securely fix the central contact or coaxial contact in the fixing position and, in particular, to fix it at least partially within the contact device.

[0142] Another aspect of the present invention relates to a method for detaching a central contact or coaxial contact from a connector, in particular a connector as described herein, wherein the method comprises the steps, in particular in this order: Guiding a tool in the insertion direction of the connector into the contact device, and releasing the connection or fixing the central contact or coaxial contact to the contact device.

[0143] The method for detaching the coaxial contact from a connector may further include, in particular, a step of removing the central contact or coaxial contact from the contact device, for example by pulling out the central contact or coaxial contact, in particular substantially against the assembly direction and / or in the insertion direction.

[0144] Releasing the connection or fixing can, in particular, involve a self-returning deflection of the clip, especially an elastically rebounding deflection of one or more spring hooks of the clip radially inwards. Due to this self-returning deflection of the clip, the fixing position is no longer limited by the clip in the opposite direction to the mounting direction and / or axial direction, i.e., essentially in the insertion direction.

[0145] The tool can, for example, be essentially hollow cylindrical or tubular. In particular, the tool can have an axial extent that is greater than the axial extent of the contact device.

[0146] Optionally, the tool may be closed, particularly at one end in the axial direction, and may include a radially inward-facing projection and / or one or more radially inward-facing barbs.

[0147] After being guided in the insertion direction into the contact device, and after releasing the connection or fixing it, the tool can be moved, for example, in the opposite direction to the previous guidance, i.e., essentially withdrawn in the opposite direction to the insertion direction, or passed in the insertion direction, in particular through the opening of the circuit board.

[0148] This makes it advantageously easy to detach the central or coaxial contact, and in particular, to remove it from the contact device against the mounting direction. If the tool is closed at one axial end and / or has a radially inward-facing projection or barb, the central or coaxial contact can advantageously be easily removed from the contact device with the tool through the opening in the circuit board.

[0149] Exemplary, preferred and alternative embodiments of the aspect relating to the method for releasing a central contact or coaxial contact from a connector, and their effects, may in particular correspond to those explained in relation to the aspects relating to the connector and / or the aspect relating to the method for manufacturing a connector, and vice versa.

[0150] The following describes embodiments of the invention in more detail with reference to the accompanying figures. It is understood that the present invention is not limited to these embodiments and that individual features of the embodiments can be combined to form further embodiments within the scope of the accompanying claims.

[0151] It shows: Figure 1a a perspective view of a connector according to an embodiment of the present invention; Figure 1b a sectional view of a connector according to an embodiment of the present invention; Figure 2a a sectional view of a connector according to an embodiment of the present invention; Figure 2b a sectional view of a connector according to an embodiment of the present invention; Figure 3a a coaxial contact according to an embodiment of the present invention; Figure 3c a coaxial contact according to an embodiment of the present invention; Figure 3c a clip according to an embodiment of the present invention; Figure 4a a contact pin according to an embodiment of the present invention; Figure 4c a coaxial contact according to an embodiment of the present invention; Figure 4c a sectional view of a coaxial contact according to an embodiment of the present invention;Figure 5 shows a flowchart of a method for manufacturing a connector according to an embodiment of the present invention; and Figure 6 shows a flowchart of a method for detaching a coaxial contact from a connector according to an embodiment of the present invention.

[0152] Fig. 1a Figure 1 shows a perspective view of a connector 1, according to an embodiment of the present invention.

[0153] Fig. 1b Figure 1 shows a sectional view of a connector 1, according to an embodiment of the present invention. The connector is shown in Figure 1. Fig. 1b The connector shown (1) can in particular be used in the Fig. 1a The connectors shown correspond to connector 1. The sectional view in Fig. 1b in particular represents a section in a plane which extends essentially perpendicular to the axial direction A, and / or to the insertion direction S, and / or to the assembly direction M.

[0154] Fig. 2aFigure 1 shows a sectional view of a connector 1, according to an embodiment of the present invention. The sectional view in Fig. 2a This in particular represents a section in a plane which extends essentially in the axial direction A and in the radial direction R, where the axial direction A can be essentially parallel to the insertion direction S and / or the assembly direction M. The in Fig. 2a The connector shown (1) can in particular be used in the Figures 1a and 1b The connector shown corresponds to connector 1.

[0155] Fig. 2b Figure 1 shows a sectional view of a connector 1, according to an embodiment of the present invention. The sectional view in Fig. 2b This in particular represents a section in a plane which extends essentially in the axial direction A and in the radial direction R, where the axial direction A can be essentially parallel to the insertion direction S and / or the assembly direction M. The in Fig. 2bThe connector shown (1) can in particular be used in the Figures 1a, 1b and 2a The connectors shown correspond to connector 1, with the connectors shown in the Figures 2a and 2b The contact devices 30 of the connector 1 shown, in particular, have different central contacts 50, especially coaxial contacts 50, arranged.

[0156] As through the Figures 1a to 2b As shown, the connector 1 in particular has a printed circuit board 10, on the upper side of which a connector body 20 is arranged in the axial direction A.

[0157] The connector body 20 is in particular essentially hollow cylindrical or, in other words, tubular in shape, wherein the connector body 20, as illustrated in the figures, is not limited to a strictly round shape.

[0158] The connector body 20 has several mounting sections 22 on one side facing the circuit board 10, i.e., on a side lower in the axial direction A, which in particular extend further downwards in the axial direction A than the rest of the connector body 20. The connector body 20 can, for example, have two, three, four, five, six or more mounting sections 22, which in particular are arranged substantially distributed in the circumferential direction U on the connector body 20.

[0159] Between two fastening sections 22 that are essentially adjacent in the circumferential direction U, recesses are formed in the axial direction A.

[0160] The connector body 20 can be advantageously fixed precisely to the circuit board 10 by means of the fastening sections 22. At the same time, accessibility and / or visual inspection of a contact area of ​​the circuit board 10, in which the contact pins 40 make contact with the circuit board 10, can be ensured.

[0161] The connector body 20 can be fixed to the printed circuit board 10, for example, by means of fastening elements 23, which are arranged in the area of ​​the fastening sections 22, in a form-fit and / or friction-fit manner. Alternatively or additionally, the connector body 20 can be material-fitted to the printed circuit board 10, for example by soldering, in particular reflow soldering.

[0162] The fastening means 23 can, for example, comprise elastically restorable and, in particular, solderable fixing pins, which are designed to engage in the circuit board 10 in an elastically restorable manner essentially in the axial direction A.

[0163] The connector body 20 can in particular have a first coding 24, which can be arranged, for example, on an inner circumferential side of the connector body 20, and can in particular extend substantially parallel to the axial direction A and / or to the plugging direction S.

[0164] The coding 24 is specifically designed to engage with a complementary coding of a connector complementary to connector 1 during coupling to create an electrically conductive contact. This advantageously ensures a predetermined relative alignment between connector 1 and a complementary connector 1.

[0165] Furthermore, the connector body 20 can, in particular, have fixing means 26, such as a fixing receptacle 26. The fixing receptacle 26 can, in particular, comprise a recess or, in other words, a groove, which, in particular, extends substantially in the radial direction R from an inner circumferential side of the connector body 20 and / or an outer circumferential side of the connector body 20.

[0166] The fixing receptacle 26 can be distributed around the connector body 20 in the circumferential direction U, or can be formed essentially continuously around the connector 20 in the circumferential direction U, in particular apart from possible projections or recesses due to codings, such as the first coding 24.

[0167] The fixing receptacle 26 represents an advantageous and in particular protected, especially touch-protected groove, for fastening a complementary connector to the connector body 20.

[0168] The connector body 20 is designed to be electrically conductive and surrounds the contact device 30 in the radial direction R. As a result, the connector body 20 advantageously provides shielding for the contact device 30 and for the contacts arranged therein.

[0169] The contact device 30 can be, in particular, substantially hollow-cylindrical or tubular in shape, wherein the contact device 30 has several first contact receptacles 32 in its contact body 31, which extends substantially in the circumferential direction U and in the axial direction A, each for receiving a contact pin 40. A second contact receptacle 34 is, in particular, formed at the radial center of the contact device 30 for arranging or fixing a central contact 50 or coaxial contact 50 on or in the contact device 30. Although only a single second contact receptacle 34 is shown in the figures, in exemplary embodiments of the connector 1 the contact device 30 can have several second contact receptacles, each for arranging or fixing a central contact 50 or coaxial contact 50 on or in the contact device 30.If several central contacts 50 or coaxial contacts 50 can be mounted on or in the contact device 30, the contact device 30 can in particular have a comparatively reduced number of first contact receptacles 32 for receiving one contact pin 40 each.

[0170] This makes it advantageous to ensure a predetermined connector geometry, and in particular a predetermined diameter of the connector 1, by means of the contact device 30.

[0171] The contact device 30 is arranged, in particular in the radial direction R, within the connector body 20. The contact device 30 may, in particular, have a stop projection 33 which projects outwards from the contact body 31 in the radial direction R. The stop projection 33 is, in particular, abutted by a complementary stop 28 of the connector body 20 substantially in the axial direction A and / or in the insertion direction S.

[0172] The contact body 31 can further, in particular, have a second coding 38, which extends substantially outwards in the radial direction R. The second coding 38 has, in particular, an outward extension in the radial direction R that is greater than the outward extension of the stop projection 33 in the radial direction.

[0173] This advantageously ensures a predetermined mounting position between the connector body 20 and the contact device 30 or its contact body 31. In particular, a predetermined relative positioning of the connector 20 relative to the contact device 30 in the circumferential direction U can be ensured.

[0174] Furthermore, the contact body 31 can in particular have a third coding 39, which, for example, comprises a recess directed substantially inwards in the radial direction R. The third coding 39 is particularly designed to engage with a complementary projection of a connector that is complementary to the connector 1. This advantageously prevents unintended coupling or contact with an unsuitable connector.

[0175] The contact device 30 can be attached to the circuit board 10, in particular by means of the several contact pins 40, wherein in particular one contact pin 40 is arranged in each of a first contact receptacle 32, and in particular by means of a material bond, for example by soldering, in particular by means of reflow soldering.

[0176] The contact pins 40 arranged in the contact device 30 can, in particular, be connected to the circuit board 10 by a part 41 that contacts the circuit board 10. Optionally, the parts 41 that contact the circuit board 10 can project from the circuit board 10 on a side facing away from the contact device 30.

[0177] This makes it advantageously easy to solder the contact pins 40 to the circuit board 10, in particular from a side of the circuit board 10 that is lower in the axial direction A, or in other words, a side of the circuit board 10 opposite the connector body 20 and / or the contact device 30.

[0178] Fig. 3a Figure 50 shows a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. The contact shown in Figure 50 is a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. Fig. 3a The coaxial contact 50 shown can in particular correspond to the coaxial contact 50 as shown in the Figures 1a, 1b and 2a shown.

[0179] Fig. 3b Figure 50 shows a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. The contact shown in Figure 50 is a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. Fig. 3b The coaxial contact 50 shown can in particular correspond to the coaxial contact 50 as shown in the Figures 1a, 1b , 2a and 3a shown. The one in Fig. 3b The coaxial contact 50 shown can in particular be used in Fig. 3a as shown, but without the clip 70 arranged on the coaxial contact 50.

[0180] Fig. 4b Figure 50 shows a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. The contact shown in Figure 50 is a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. Fig. 4b The coaxial contact 50 shown can in particular correspond to the coaxial contact 50 as shown in the Figures 1a, 1b , and 2b shown.

[0181] Fig. 4c Figure 1 shows a sectional view of a central contact 50 or coaxial contact 50, according to an embodiment of the present invention. The section plane of the Fig. 4cThe sectional view shown extends essentially parallel to the axial direction A and the radial direction R. The axial direction A can be essentially parallel to the insertion direction S, and in particular, oppositely parallel. The Fig. 4c The coaxial contact 50 shown can in particular correspond to the coaxial contact 50 as shown in the Figures 1a, 1b , 2b and 4b shown.

[0182] Fig. 3c shows a clip 70, according to an embodiment of the present invention. The one in Fig. 3c Clip 70 shown may in particular correspond to Clip 70 as shown in the Figures 1a, 1b , 2a, 2b , 3a , 4b and 4c shown.

[0183] As through the Figures 1a, 1b , 2a, 2b , 3a, 3b, 3c , 4b and 4cAs shown, the second contact receptacle 34 of the contact device 30 is particularly designed to accommodate one, and in particular exactly one, central contact 50 or coaxial contact 50, at least partially. In particular, the central contact or coaxial contact 50 can project through the opening 12 of the circuit board 10 in a state mounted on the contact device 30, in particular substantially opposite to the mounting direction M.

[0184] The second contact receptacle 34 forms in particular a through-opening which is arranged radially within the first contact receptacles 32 of the contact body 31.

[0185] The second contact point 34 can in particular have a stop projection 36 which projects inwards in the radial direction R from the second contact point 34.

[0186] The stop projection 36 is specifically designed to engage with a mounting projection 56, substantially in the axial direction A and / or in the mounting direction M, when the central contact 50 or coaxial contact 50 is guided into the second contact receptacle 34 in the mounting direction M. The mounting projection 56 extends, substantially in the radial direction R, outwards from the central contact 50 or coaxial contact 50.

[0187] The stop between stop projection 36 and mounting projection 56 is specifically designed to block movement of the central contact 50 or coaxial contact 50 in the mounting direction M and / or in the axial direction A beyond the stop. This allows the central contact 50 or coaxial contact 50 to be advantageously positioned in a predetermined fixing position on or in the second contact receptacle 34.

[0188] The central contact 50 or coaxial contact 50 can, in particular, have a clip receptacle 53. The clip receptacle 53 comprises, in particular, a section of the central contact 50 or coaxial contact 50 that is offset inwards in the radial direction R along the axial direction A. The clip receptacle 53 is limited on a front side in the axial direction A and / or in the mounting direction M, in particular by a support projection 57, which extends further outwards in the radial direction R than the clip receptacle 53. On a rear side in the axial direction A and / or in the mounting direction M, the clip receptacle 53 is limited, in particular by the mounting projection 56, which extends further outwards in the radial direction R than the clip receptacle 53.

[0189] The clip receptacle 53 therefore advantageously forms a section limited in the axial direction A and / or in the mounting direction M, in which the clip 70 is positively locked, in particular positively locked on both sides in the axial direction A and / or in the mounting direction, to the central contact 50 or coaxial contact 50. The clip receptacle 53 thus advantageously ensures that the clip 70 is held at a predetermined relative position to the central contact 50 or coaxial contact 50, in particular on an outer circumferential side of the central contact 50 or coaxial contact 50.

[0190] If the central contact 50 or coaxial contact 50 is moved in a mounted state against the mounting direction M, this movement is advantageously limited by a stop of one or more spring hooks 72 of the clip 70 against a fixing projection 37 of the second contact receptacle 34. The fixing projection 37 is, in particular, a projection of the contact body 31 that projects substantially inwards in the radial direction R. At this stop, the clip 70 is advantageously supported, in particular, by the support projection 57 of the central contact 50 or coaxial contact 50.

[0191] This advantageously secures the central contact 50 or coaxial contact 50 to the contact device 30 in the assembled state. If the stop of the clip 70 relative to the fixing projection 37 is not released, the assembled state of the central contact 50 or coaxial contact 50 constitutes, in particular, a non-damage-free or non-destructive fixing or arrangement of the central contact 50 or coaxial contact 50 on the contact device 30.

[0192] If the stop of the clip 70 is released relative to the fixing projection 37, for example by an elastically restorable deflection or deformation of the spring hooks 72 of the clip 70, the assembled state of the central contact 50 or coaxial contact 50 forms in particular a damage-free, and especially non-destructively releasable, fixing or arrangement of the central contact 50 or coaxial contact 50 on the contact device 30.

[0193] If the clip 70 is not already arranged on the clip receptacle 53 of the central contact 50 or coaxial contact 50 before the central contact 50 or coaxial contact 50 is guided into the second contact receptacle 34, and is inserted together with the central contact 50 or coaxial contact 50, the clip 70 can be guided, in particular, essentially in the insertion direction S, into the second contact receptacle 34, and onto the clip receptacle 53 of the central contact 50 or coaxial contact 50.

[0194] The central contact 50 or coaxial contact 50 can have its largest diameter, particularly in the area of ​​the mounting projection 56, i.e., especially at the mounting projection 56 itself. The diameter of the support projection 57 is, in particular, smaller than the diameter of the mounting projection 56. The support projection 57 is positioned further forward in the axial direction A and / or in the mounting direction M than the mounting projection 56. The clip receptacle 53, which extends axially essentially between the mounting projection 56 and the support projection 57, has, in particular, a diameter that is smaller than both the diameter of the mounting projection 56 and the diameter of the support projection 57.

[0195] The mounting projection 56 can, but is not limited to, have a diameter of approximately 3.8 mm to approximately 5.0 mm, in particular approximately 4.1 mm to approximately 4.8 mm. The support projection 57 can, but is not limited to, have a diameter of approximately 3.4 mm to approximately 4.3 mm, in particular approximately 3.7 mm to approximately 4.1 mm. The clip receptacle 53 can, but is not limited to, have a diameter of approximately 2.7 mm to approximately 4.0 mm, in particular approximately 3.0 mm to approximately 3.7 mm.

[0196] At a front end in the axial direction A and / or in the mounting direction M, the central contact 50 or coaxial contact 50 may in particular have a first conductor receptacle 51.

[0197] The first ladder recording 51 can be seen, as shown by the Figures 2a, 2b 3a, 3b , 4b and 4bThe figure shows a receptacle for arranging a complementary conductor in the insertion direction S. The first conductor receptacle 51 can, for example, comprise several elastically resilient first conductor receptacle prongs.

[0198] In exemplary embodiments, the central contact 50 or coaxial contact 50 can in particular have a second conductor receptacle 55 radially within the first conductor receptacle 51. The second conductor receptacle 55 can in particular comprise several elastically resilient second conductor receptacle prongs.

[0199] As through the Figures 2a, 2b , 3a, 3b , 4b and 4c As illustrated, the various mountable central contacts 50 or coaxial contacts 50 advantageously allow different complementary conductors of complementary connectors to be electrically connected to the connector 1.

[0200] At a rear end in the axial direction A and / or in the mounting direction M, the central contact 50 or coaxial contact 50 may in particular have a third conductor receptacle 58.

[0201] The third ladder receptacle 58 can, as shown by the Figures 2a, 2b 3a, 3b , 4b and 4b shown, a recording for the arrangement of a complementary conductor 60 opposite the insertion direction S.

[0202] As exemplified in the Figures 2b and 4b As shown, the third conductor receptacle 58 can have a screw-in insert 59, for example, for attaching a shield to a conductor 60, which is exposed and can be connected to the third conductor receptacle 58 in an electrically conductive manner. The shield of the exposed conductor 60 can be reversibly connected to, or already connected to, a shield of the central contact 50 or coaxial contact 50, particularly by means of the screw-in insert 59.

[0203] Furthermore, the shielding of the conductor 60, which is particularly exposed, can be connected, in particular by crimping and / or soldering, to the shielding which the central contact 50 or coaxial contact 50 has.

[0204] As exemplified in Fig. 2a As shown, the third conductor receptacle 58 can have a stepped contour on an outer circumferential side, for example for fastening insulation of a cable which can be connected to the third conductor receptacle 58 and electrically conductively contacted.

[0205] The central contact 50 or coaxial contact 50 can be soldered or is soldered to a complementary conductor, particularly in the area of ​​one of the conductor receptacles 51, 55, 58.

[0206] As further exemplified by the Figures 2a , 3a and 3bAs shown, the central contact 50 or coaxial contact 50 can have a groove 52 at an axially forward end A, which is substantially circumferential in the direction U, for example for the arrangement of a ring 5, such as a type-marking ring with a predetermined optically visible marking, or an O-ring.

[0207] As through the Figures 2a, 2b , 3a, 3b , 4b and 4c As illustrated, the various mountable central contacts 50 or coaxial contacts 50 advantageously allow different complementary conductors of complementary connectors to be electrically connected to the connector 1.

[0208] Clip 70, as especially in Fig. 3cAs shown, the clip 70 can in particular have a substantially curved plate shape, wherein several spring hooks 72, for example opposite each other, spread radially outwards from a clip body 74. The clip body 74 of the clip 70 in particular forms a substantially tubular base body, which in cross-section is substantially C-shaped.

[0209] The spring hooks 72 exhibit, contrary to the axial direction A, an increasing outward spreading in the radial direction R. The spring hooks 72 can be connected to the clip body 74, in particular at an end of the clip 70 that is forward in the axial direction A. Furthermore, the spring hooks 72 can be separated from the clip body 74, in particular at an end that is rearward in the axial direction.

[0210] In cross-section, particularly in a cross-section transverse to the axial direction A, the clip 70 can be substantially C-shaped. In other words, the clip 70 can be substantially tubular, wherein the tubular wall is completely cut through at one point in the circumferential direction U along the axial direction A. In further other words, the clip 70 can be substantially circular in cross-section, wherein the circle is not closed in the circumferential direction U, but in particular has two ends adjacent to each other in the circumferential direction U.

[0211] Due to the essentially C-shaped cross-section of the clip 70, the inner diameter of the clip 70 can be advantageously adapted in a simple elastically restorable manner, in particular for the arrangement of the clip 70 on the clip receptacle 53 of the central contact 50 or coaxial contact 50.

[0212] Fig. 4ashows a contact pin 40, according to an embodiment of the present invention. The one in Fig. 4a The contact pin 40 shown can in particular correspond to contact pin 40 as shown in the Figures 1a, 1b , 2a and 3a shown.

[0213] As in Fig. 4a As shown, the contact pin 40 can in particular be formed essentially in the shape of a pin. The contact pin 40 has in particular a contact pin body 42 which extends essentially in the axial direction A.

[0214] At an axially forward end A of the contact pin body 42, the contact pin 40 has, in particular, a conductor receptacle 45. The conductor receptacle 45 can, in particular, have one or more grooves 46 which divide the conductor receptacle 45 circumferentially U into several conductor receptacle prongs, which are, in particular, elastically resilient. The conductor receptacle 45 is, in particular, configured to be electrically conductive and, in particular, physically contacted by a complementary connector in the insertion direction S. This advantageously ensures reliable contact with the contact pin 40.

[0215] The contact pin body 42 can, in particular, have one or more fixing projections 43, 44, which project substantially in the radial direction R from the contact pin body 42. The one or more fixing projections 43, 44 can, in particular, project approximately 0.2 mm to approximately 0.05 mm, and especially approximately 0.15 mm to approximately 0.08 mm, from the contact pin body 42. This allows the fixing projections 43, 44 to advantageously form an interference fit with the first contact receptacle 32 of the contact device 30, so that the contact pins 40 are advantageously frictionally engaged or attachable to the contact device 30.

[0216] Furthermore, the contact pin 40 can have a part 41 at an axially rear end A of the contact pin body 42 that contacts the printed circuit board 10. The part 41 contacting the printed circuit board 10 can, in particular, have a smaller diameter, especially an outer diameter, than the contact pin body 42. For example, the contact pin body 42 can have a diameter, especially an outer diameter, in the range of approximately 1.2 mm to approximately 2.0 mm. The part 41 contacting the printed circuit board 10 can, for example, have a diameter, especially an outer diameter, in the range of approximately 0.4 mm to approximately 1.0 mm.

[0217] This makes contact pin 40 advantageously designed for the transmission of comparatively low-frequency electrical signals.
