At least one connector side has mechanical operative connection means which "firmly" interconnects the corresponding connector part and the associated end of the adapter, ie the connection is under normal circumstances no longer releasable or releasable against an increased force.
- the active connection means are arranged opposite the conductors so that the greatest possible offset in the axial and lateral direction is possible.

- At least one of the openings in the outer conductor of the first, respectively the second connector part, which serves for insertion of the adapter has along an edge a limiting element, preferably a delimiting ring, which consists of a non-conductive material.

- the limiting element can be arranged in a recess of the outer conductor of the first connector part.
- the limiting element may be fastened in the recess, for example by pressing in and / or snapping in and / or gluing.

Description
Die vorliegende Erfindung liegt auf dem Gebiet der Koaxialverbinder für Leiterplatten.The present invention is in the field of coaxial connectors for printed circuit boards.
Nach dem Bestücken von Leiterplatten mit SMD (Surface Mounted Device) - Bauteilen und dem anschliessenden Verlöten werden Leiterplatten hochfrequenzmässig miteinander kontaktiert. Hierbei müssen Lage- und Positionsungenauigkeiten in radialer und axialer Richtung kompensiert werden, damit die Hochfrequenzeigenschaften beibehalten werden. In der Regel ist eine Mehrzahl von Kontaktpunkten gleichzeitig zu verbinden. Hierzu werden blind steckbare koaxiale Verbinder verwendet, welche zwei örtlich übereinander angeordnete koaxiale Kontaktpunkte unter Berücksichtigung eines axialen und radialen Versatzes miteinander verbinden. Zu koaxialen Kontaktpunkten gehören z.B. koaxiale Kabel, Printplatten mit entsprechenden Layoutstrukturen, Gehäuseeinführungen wie Filter-/Duplexereinkopplungen.After the assembly of printed circuit boards with SMD (Surface Mounted Device) components and the subsequent soldering, printed circuit boards are contacted with regard to their frequency. This position and position inaccuracies in the radial and axial direction must be compensated so that the high-frequency properties are maintained. As a rule, a plurality of contact points are to be connected simultaneously. For this purpose, blind pluggable coaxial connectors are used, which connect two locally superposed coaxial contact points, taking into account an axial and radial offset with each other. Coaxial contact points include e.g. Coaxial cables, printed circuit boards with corresponding layout structures, housing entries such as filter / duplexer couplings.
Aus dem Stand der Technik sind blind steckbare Leiterplatten-Koaxialverbinder bekannt. Diese weisen einen mehrteiligen Aufbau mit einem ersten und einem zweiten Verbinderteil auf, die über ein Adapterstück miteinander wirkverbunden werden. Ein Nachteil der aus dem Stand der Technik bekannten Verbinder besteht darin, dass diese eine lageabhängige Störung aufweisen, welche sich negativ auf die Übertragungseigenschaften auswirken kann.Blind pluggable printed circuit board coaxial connectors are known from the prior art. These have a multi-part construction with a first and a second connector part, which are operatively connected to each other via an adapter piece. A disadvantage of the connectors known from the prior art is that they have a position-dependent perturbation, which can adversely affect the transmission properties.
Weitere Verbinder mit einem der gattungsgemässen Art sind aus
Eine Aufgabe der Erfindung besteht darin, einen Verbinder der gattungsgemässen Art zu zeigen, welcher verbesserte Übertragungseigenschaften aufweist.An object of the invention is to show a connector of the generic type, which has improved transmission characteristics.
Diese Aufgabe wird durch den m unabhängigen Anspruch definierten Verbinder gelöst.This object is achieved by the m independent claim defined connector.
Die aus dem Stand der Technik bekannten Verbinder kommen u. a. in Sende- und Empfangsgeräten zum Einsatz. Z.B. werden auf speziellen koaxialen Verbindungen Sende- und Empfangssignale zusammengeführt. Sende und Empfangssignale unterscheiden sich durch die Nutzung eines jeweilig definierten Frequenzspektrums. Für einen störungsfreien Betrieb ist es notwendig, dass keine spektralen Anteile des Sendesignals in das Spektrum des Empfangssignals fallen. Dieses Verhalten muss auch für Vibration und/oder Stossbelastungen gegeben sein. Mögliche Quellen solcher Störsignale aus dem Sendesignal sind z.B. passive Intermodulation durch schlechte, respektive mehrere mechanische Kontakte.The known from the prior art connectors come u. a. used in transmitting and receiving devices. For example, are combined on special coaxial connections transmit and receive signals. Transmit and receive signals differ by the use of a respective defined frequency spectrum. For trouble-free operation, it is necessary that no spectral components of the transmission signal fall into the spectrum of the received signal. This behavior must also be given for vibration and / or shock loads. Possible sources of such spurious signals from the transmission signal are e.g. passive intermodulation due to bad, respectively several mechanical contacts.
Ein weiterer Mechanismus um Störsignale zu erzeugen, resultiert aus der Phasen/Frequenzmodulation des Sendesignals. Dieser Effekt kann durch eine schwache Auskopplung des Sendesignals in einer resonanten Struktur, deren Resonanzfrequenz z.B. durch Vibration oder mechanische Stösse variabel ist, erzeugt werden. Resonante Strukturen können in einem Verbinder durch mehrere zueinander ungünstig angeordnete Kontaktstellen entstehen, welche sich bei immer höheren Frequenzen besonders negativ auswirken. Speziell bei Verbindern der erfindungsgemässen Gattung, welche zur Kompensation von geometrischen Abweichungen gedacht sind, und damit eine veränderbare Geometrie aufweisen, können solche Probleme auftreten. Der erfindungsgemässe Verbinder vermeidet negative Effekte und verbessert damit die Übertragung der Signale, insbesondere bei hohen Frequenzen. Die störende Auskopplung des Sendesignals am Aussenleiter des Verbindungselements wird soweit reduziert, dass sie keinen negativen Einfluss mehr hat.Another mechanism to generate spurious signals results from the phase / frequency modulation of the transmission signal. This effect can be generated by a weak coupling of the transmission signal in a resonant structure whose resonance frequency is variable, for example, by vibration or mechanical shocks. Resonant structures can be interconnected in a connector by a plurality of each other unfavorably arranged contact points arise which have particularly negative effects at ever higher frequencies. Especially with connectors of the genus of the invention, which are intended to compensate for geometric deviations, and thus have a variable geometry, such problems may occur. The connector according to the invention avoids negative effects and thus improves the transmission of the signals, in particular at high frequencies. The disturbing decoupling of the transmission signal at the outer conductor of the connecting element is reduced so much that it no longer has a negative influence.
Bei den aus dem Stand der Technik bekannten Verbinder wird durch die Aussenleitergeometrie des Verbindungselementes (Adapters) und den mit diesem wirkverbundenen Verbinderteile, welche gemeinsam eine axiale und radiale Beweglichkeit des Verbinders gewährleisten, in gewissen Positionen ein geometrisch variabler Resonanzraum gebildet, der sich negativ auf die Übertragungseigenschaften auswirkt. Der Adapter wirkt über ringförmig angeordnete Federzungen mit einer Innenfläche einer Öffnung eines elektrisch leitenden Gehäuses eines gekoppelten Verbinderteils zusammen. Die Verstimmung der Resonanzfrequenz erfolgt dabei dadurch, dass bei einer seitlichen Auslenkung (Abkippen) des Adapters, der Aussenleiter des Adapters (beabstandet zu den Federzungen) einer Kante des elektrisch leitenden Gehäuses des gekoppelten Verbinderteils nahe kommt. Sobald der Abstand zwischen der Kante des Gehäuses und dem Aussenleiter des Adapters ein gewisses Mass unterschreitet, wird ein Schwingkreis gebildet, welcher den Resonator kapazitiv belastet und dadurch zu einer Beeinflussung der Resonanzfrequenz führt.In the known from the prior art connector is formed by the outer conductor geometry of the connecting element (adapter) and the operatively connected thereto connector parts, which together ensure axial and radial mobility of the connector, in certain positions, a geometrically variable resonance chamber, which adversely affects the Transmission properties. The adapter cooperates via annularly arranged spring tongues with an inner surface of an opening of an electrically conductive housing of a coupled connector part. The detuning of the resonant frequency is effected in that, in the case of a lateral deflection (tilting) of the adapter, the outer conductor of the adapter (spaced apart from the spring tongues) comes close to an edge of the electrically conductive housing of the coupled connector part. As soon as the distance between the edge of the housing and the outer conductor of the adapter falls below a certain level, a resonant circuit is formed, which capacitively loads the resonator and thereby leads to an influence on the resonant frequency.
Ein erfindungsgemässer Verbinder vermeidet dieses Problem, indem er ein Begrenzungselement, z.B. in Form eines Begrenzungsringes aufweist, welcher die maximale seitliche Auslenkung (Kippbewegung) des Adapters gegenüber dem gefährdeten Verbinderteil reduziert. Eine Ausführungsform eines erfindungsgemässen Verbinders, welcher dieses Problem vermeidet, weist einen ersten und einen zweiten Verbinderteil und einen im montierten Zustand zwischen diesen angeordneten Adapter auf, welcher mit dem ersten und dem zweiten Verbinderteil elektrisch leitend koppelbar ist und zum gelenkigen Wirkverbinden der beiden Verbinderteile dient. Der erste und der zweite Verbinderteil weisen je einen Innenleiter und einen Aussenleiter auf, welche von einem Isolator gegeneinander gehalten werden. Der Adapter weist ebenfalls einen Innenleiter und einen Aussenleiter auf, welche von einem Isolator gegeneinander gehalten werden. Der Aussenleiter des ersten, respektive des zweiten Verbinderteils, weisen je eine Öffnung auf, die so ausgestaltet ist, dass der Adapter in diese beweglich eingesteckt werden kann. Der Aussenleiter des Adapters weist an seinen beiden Enden elastische Federzungen mit radial vorstehenden Kontaktwulsten auf, welche in montiertem Zustand in die Öffnungen des ersten, respektive des zweiten Verbinderteils eingesteckt sind und dort mit Kontaktflächen elektrisch leitend zusammenwirken. Die elastischen Federzungen dienen zusammen mit den Kontaktwulsten zur Herstellung und Aufrechterhaltung einer sicheren elektrischen Verbindung. Zumindest eine der Öffnungen im Aussenleiter des ersten, respektive des zweiten Verbinderteils, welche zum Einstecken des Adapters dient, weist entlang einer Kante ein Begrenzungselement, vorzugsweise einen Begrenzungsring, auf, welcher aus einem nicht leitenden Material besteht. Der Begrenzungsring dient zum Begrenzen der maximal möglichen seitlichen Auslenkung des Adapters gegenüber dem entsprechenden Verbinderteil und zum Einstellen des minimal möglichen Abstandes zwischen dem Aussenleiter des Adapters und dem Aussenleiter des Verbinderteils. Der Begrenzungsring dient zum Verhindern von schädlichen resonanten Strukturen. Der Begrenzungsring kann sich über die gesamte Breite des Gehäuses eines Verbinderteils erstrecken oder einen Teil davon bilden. Der Begrenzungsring kann z.B. durch Schnappen oder Schrauben am Gehäuse des Verbinderteils befestigt werden.A connector according to the invention avoids this problem by having a limiting element, eg in the form of a limiting ring, which reduces the maximum lateral deflection (tilting movement) of the adapter relative to the endangered connector part. An embodiment of a connector according to the invention, which avoids this problem, has a first and a second connector part and an adapter arranged between them in the assembled state, which is electrically conductively coupled to the first and the second connector part and serves for the articulated connection of the two connector parts. The first and the second connector part each have an inner conductor and an outer conductor, which are held by an insulator against each other. The adapter also has an inner conductor and an outer conductor, which are held by an insulator against each other. The outer conductor of the first, respectively the second connector part, each have an opening which is designed so that the adapter can be inserted into this movable. The outer conductor of the adapter has at its two ends elastic spring tongues with radially projecting Kontaktwulsten, which are inserted in the assembled state in the openings of the first, respectively the second connector part and there electrically cooperate with contact surfaces. The elastic spring tongues together with the contact beads serve to produce and maintain a secure electrical connection. At least one of the openings in the outer conductor of the first, respectively the second connector part, which serves for insertion of the adapter, has along an edge a limiting element, preferably a delimiting ring, which consists of a non-conductive material. The limiting ring serves to limit the maximum possible lateral deflection of the adapter relative to the corresponding connector part and for setting the minimum possible distance between the outer conductor of the adapter and the outer conductor of the connector part. The limiting ring serves to prevent damaging resonant structures. The restriction ring may extend over or form part of the entire width of the housing of a connector part. The limiting ring can be fastened, for example, by snapping or screwing on the housing of the connector part.
In einer Ausführungsform weist der Koaxialverbinder einen ersten und einen zweiten Verbinderteil und einem zwischen diesen angeordneten Adapter auf. Der Adapter ist im montierten (wirkverbundenen) Zustand in einer Öffnung eines Aussenleiters des ersten Verbinderteils seitlich kippbar angeordnet. Ein Aussenleiter des Adapters wirkt mit dem Aussenleiter des ersten Verbinderteils z.B. über elastische Federzungen ringförmig zusammen. Andere Wirkverbindungen sind möglich, solange zumindest die seitliche Beweglichkeit nicht eingeschränkt wird. Ein Begrenzungselement aus einen isolierenden Material ist im Bereich des Eingangs der Öffnung angeordnet. Es dient dazu, das seitliche Auslenken des Adapters kontrolliert zu begrenzen. Das Begrenzungselement ist mit Vorteil ringförmig ausgestaltet und weist ein Loch auf. Je nach Ausführungsform kann das Loch zylindrisch oder konisch ausgestaltet sein. Andere Ausgestaltungen sind möglich. Das Begrenzungselement kann in einer Ausnehmung des Aussenleiters des ersten Verbinderteils angeordnet sein. Das Begrenzungselement kann z.B. durch Einpressen und/oder Einschnappen und/oder Einkleben in der Ausnehmung befestigt sein. Das Begrenzungselement kann aber auch Teil eines Aussengehäuses des ersten Verbinderteils sein. In diesem Fall kann der Aussenleiter des ersten Verbinderteils in das Begrenzungselement eingepresst und/oder eingeschnappt und/oder eingeklebt sein. Das Begrenzungselement ist mit Vorteil aus Kunststoff hergestellt. Andere isolierende Materialien sind möglich. Z.B. kann das Begrenzungselement aus einem elastischen Material hergestellt werden, welches bei einer Deformation durch den Adapter eine Rückstellkraft auf diesen ausübt. Der Aussenleiter des Adapters kann einen umlaufenden Wulst aufweisen, welcher mit dem Begrenzungselement definiert zusammenwirkt und dessen maximale seitliche Auslenkung bestimmt.In one embodiment, the coaxial connector has a first and a second connector part and an adapter arranged between them. The adapter is arranged laterally tiltable in the mounted (operatively connected) state in an opening of an outer conductor of the first connector part. An outer conductor of the adapter interacts annularly with the outer conductor of the first connector part, for example via elastic spring tongues. Other active compounds are possible as long as at least the lateral mobility is not restricted. A limiting element made of an insulating material is arranged in the region of the entrance of the opening. It serves to limit the lateral deflection of the adapter controlled. The limiting element is advantageously designed annular and has a hole. Depending on the embodiment, the hole may be cylindrical or conical. Other embodiments are possible. The limiting element can be arranged in a recess of the outer conductor of the first connector part. The limiting element may be fastened in the recess, for example by pressing in and / or snapping in and / or gluing. The limiting element can also be part of an outer housing of the first Be connector parts. In this case, the outer conductor of the first connector part can be pressed into the limiting element and / or snapped and / or glued. The limiting element is advantageously made of plastic. Other insulating materials are possible. For example, the limiting element can be made of an elastic material which exerts a restoring force on it when deformed by the adapter. The outer conductor of the adapter may have a circumferential bead, which cooperates defined with the limiting element and determines its maximum lateral deflection.
