Description
Die Erfindung betrifft einen elektrischen Steckverbinder zum Verbinden eines oder mehrerer Koaxialkabel mit einer Leiterplatte, ein Verbinderelement und eine diesbezügliche Verwendung.The invention relates to an electrical connector for connecting one or more coaxial cable to a printed circuit board, a connector element and a related use.
Koaxialkabel sind dazu geeignet, im Frequenzbereich von einigen kHz bis zu einigen GHz hochfrequente, breitbandige Signale wie z.B. Rundfunksignale, Radarsignale oder auch Messsignale zu übertragen. Insbesondere werden Koaxialkabel im Automotive-Bereich für automobile Hochfrequenz-Anwendungen, wie z.B. Radio Antennen, GPS-Telematik oder Navigation, GSM-Mobilfunk, HF-Bluetooth-Anwendungen sowie Funkfernbedienungen für Keyless Entry und Standheizung eingesetzt. Gerade für solche Einsatzgebiete im Automobilbereich sind jedoch hohe Anforderungen an entsprechende Steckverbinder als Schnittstelle zwischen einem oder mehrerer Koaxialkabel und einer Leiterplatte bzw. Platine zu stellen.Coaxial cables are suitable in the frequency range of several kHz to several GHz high-frequency broadband signals such. Broadcast signals, radar signals or measuring signals to transmit. In particular, automotive coaxial cables are being used for high frequency automotive applications, such as automotive electronics. Radio antennas, GPS telematics or navigation, GSM mobile radio, RF Bluetooth applications and radio remote controls for keyless entry and parking heater used. Especially for such applications in the automotive sector, however, high demands are placed on corresponding connectors as an interface between one or more coaxial cables and a printed circuit board or board.
Aus dem Stand der Technik sind speziell für die Verwendung im Automobilbereich entwickelte sogenannte FAKRA-Steckverbinder (FAKRA = Fachkreis Automobil) bekannt, welche nach DIN 72594-1 bzw. ISO 20860-1 und USCAR-18 genormt sind. Eine Besonderheit dieser Steckverbinder ist die sowohl farbliche als auch mechanische Kodierung der verschiedenen Varianten. Ferner lassen sich die Steckverbinder auch paarweise oder in Mehrfachkombinationen verarbeiten. Außerdem wurde Wert auf die speziellen Anforderungen im Automobilbereich wie Temperaturbedingungen, Vibrationen, etc. gelegt.From the state of the art so-called FAKRA connectors (FAKRA = Fachkreis Automobil) developed specifically for use in the automotive sector are known, which are standardized in accordance with DIN 72594-1 or ISO 20860-1 and USCAR-18. A special feature of these connectors is the color coding as well as the mechanical coding of the different variants. Furthermore, the connectors can also be processed in pairs or in multiple combinations. In addition, emphasis was placed on the special requirements in the automotive sector such as temperature conditions, vibrations, etc.
Obwohl herkömmliche FAKRA-Steckverbinder für spezielle Anforderungen im Automobilbereich wie Temperaturschwankungen und Vibrationen ausgelegt sind, besteht das Problem, dass Feuchtigkeit bzw. Wasser von außen über die Steckverbinder zur Leiterplatte bzw. Platine gelangen kann. Bei technischen Geräten und insbesondere bei Messinstrumenten kann schon eine geringe Feuchtigkeit im Inneren - die beispielsweise auch von Kondensation herrühren kann - die Funktion beeinträchtigen oder Messfehler verursachen. Dabei sind speziell elektrische Kontakte gefährdet, Kriechströme oder der Ausfall von Magnetkontakten können die Folge sein. Das Eindringen von Feuchtigkeit bzw. Flüssigkeit kann also zur vorübergehenden Funktionsstörung bis hin zur vollständigen Zerstörung der Leiterplatte und/oder des damit verbundenen technischen Geräts führen. Auch kann die Feuchtigkeit zur Korrosion von Teilen des Kabels, Teilen des Steckverbinders und/oder Teilen der Leiterplatte führen, was die Lebensdauer der entsprechenden Teile einschränkt.Although conventional FAKRA connectors are designed to meet specific automotive requirements such as temperature variations and vibration, there is a problem with moisture or water coming from outside through the system Connectors can get to the PCB or board. In the case of technical devices and especially with measuring instruments, even a slight moisture in the interior - which can also be due to condensation, for example - can impair the function or cause measurement errors. In particular, electrical contacts are at risk, leakage currents or the failure of magnetic contacts can be the result. The penetration of moisture or liquid can thus lead to temporary malfunction up to the complete destruction of the circuit board and / or the associated technical device. Also, the moisture can lead to corrosion of parts of the cable, parts of the connector and / or parts of the circuit board, which limits the life of the corresponding parts.
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, einen für die Anforderungen im Automobilbereich verbesserten elektrischen Steckverbinder zum Verbinden eines oder mehrerer Koaxialkabel mit einer Leiterplatte bereitzustellen. Insbesondere ist es eine Aufgabe der vorliegenden Erfindung, einen im Wesentlichen wasserdichten elektrischen Steckverbinder bereitzustellen.It is therefore an object of the present invention to provide an automotive connector improved electrical connector for connecting one or more coaxial cables to a printed circuit board. In particular, it is an object of the present invention to provide a substantially watertight electrical connector.

Der erfindungsgemäße elektrische Steckverbinder kann vorteilhafterweise ein Eindringen von Feuchtigkeit bzw. Flüssigkeit, insbesondere Wasser, in das platinenseitige Ende des Steckverbinders und/oder ein Eindringen von Feuchtigkeit bzw. Flüssigkeit zur Leiterplatte im Wesentlichen unterbinden. Somit können Funktionsstörungen und/oder ein Zerstören der Leiterplatte bzw. des damit verbundenen elektrischen Geräts aufgrund des Eindringens von Feuchtigkeit bzw. Flüssigkeit vermieden werden. Auch kann eine Korrosionsbildung an dafür anfälligen Teilen des Kabels, Teilen des Steckverbinders und/oder Teilen der Leiterplatte vermieden werden, was die Lebensdauer der entsprechenden Teile und damit die Lebensdauer des Kabels, des Steckverbinders und/oder der Leiterplatte selbst erhöht. Die erfindungsgemäßen elektrischen Steckverbinder können somit erhöhten Anforderungen, insbesondere im Automobilbereich, besser gerecht werden. So kann der erfindungsgemäße Steckverbinder gerade bei anspruchsvollen Geräten eingesetzt werden, für die beispielsweise eine bestimmte Grenze für die Luftfeuchtigkeit und/oder für Lagerungsbedingungen angegeben sind.The electrical connector according to the invention can advantageously prevent penetration of moisture or liquid, in particular water, into the board-side end of the connector and / or penetration of moisture or liquid to the circuit board substantially. Thus, malfunction and / or destruction of the circuit board or the associated electrical device due to the ingress of moisture or liquid can be avoided. Also, corrosion of susceptible parts of the cable, parts of the connector and / or parts of the circuit board can be avoided, which increases the life of the corresponding parts and thus the life of the cable, the connector and / or the circuit board itself.

In einer bevorzugten Ausführungsform des elektrischen Steckverbinders ist das Dichtungssystem derart ausgebildet, dass es im gesteckten bzw. montierten Zustand eine Dichtigkeit gemäß der Schutzklasse IP67 und/oder IP68 nach DIN EN 60529 aufweist. Vorzugsweise hält das Dichtungssystem in 1 m Wassertiefe für mindestens 48 Stunden dicht. Ein Eindringen von Feuchtigkeit in das platinenseitige Ende des Steckverbinders und/oder ein Eindringen von Feuchtigkeit zur Leiterplatte kann somit selbst bei einer relativen Luftfeuchtigkeit der Umgebung von ≤ 99% unterbunden werden.In a preferred embodiment of the electrical connector, the sealing system is designed such that it has a leak in the mated or mounted state according to the protection class IP67 and / or IP68 according to DIN EN 60529. The sealing system preferably keeps in 1 m water depth for at least 48 hours tight. Ingress of moisture into the board-side end of the connector and / or penetration of moisture to the circuit board can thus be prevented even at a relative humidity of the environment of ≤ 99%.
Das Dichtungssystem kann beispielsweise aus Kunststoff, insbesondere aus elastischem Kunststoff und/oder Gummi gebildet sein. Vorzugsweise sind der Anschlagabschnitt und die Montageplatte derart zueinander angeordnet, dass sie das dazwischenliegende Dichtungssystem zusammendrücken und es dabei elastisch verformen. Auf Grund des damit erzeugten Anpressdrucks des Dichtungssystems gegenüber dem Anschlagabschnitt und der Montageplatte kann eine erhöhte Dichtigkeit erreicht werden.The sealing system may for example be made of plastic, in particular of elastic plastic and / or rubber. Preferably, the stopper portion and the mounting plate are arranged to each other such that they compress the intermediate sealing system and thereby deform it elastically. Due to the thus generated contact pressure of the sealing system relative to the stopper portion and the mounting plate increased density can be achieved.
In einer weiteren bevorzugten Ausführungsform des elektrischen Steckverbinders ist das Verbinderelement als Spritzgussteil ausgebildet.In a further preferred embodiment of the electrical connector, the connector element is designed as an injection molded part.
Vorteilhafterweise sind der steckseitige Abschnitt, der Anschlagabschnitt und der platinenseitige Abschnitt des Verbinderelements einstückig, vorzugsweise aus Kunststoff, ausgebildet und/oder als Spritzgussteil gefertigt. Dies spart Zeit und Kosten bei der Herstellung und sorgt gleichzeitig für einen stabilen Zusammenhalt des Steckverbinders.Advantageously, the plug-side portion, the stopper portion and the board-side portion of the connector element are integrally formed, preferably made of plastic, and / or manufactured as an injection molded part. This saves time and costs in the production and at the same time ensures a stable cohesion of the connector.
In einer weiteren bevorzugten Ausführungsform des elektrischen Steckverbinders ist das Dichtungssystem auf den Anschlagabschnitt aufgespritzt.In a further preferred embodiment of the electrical connector, the sealing system is sprayed onto the stopper portion.
Durch das Aufspritzen des Dichtungssystems auf den Anschlagabschnitt ist das Dichtungssystem fest mit dem Anschlagabschnitt verbunden und sorgt somit für eine erhöhte Festigkeit und Dichtigkeit. Das Dichtungssystem kann somit auch als Bestandteil des Verbinderelements angesehen werden, oder anders ausgedrückt, das Verbinderelement kann auch das Dichtungssystem umfassen. Im montierten Zustand drückt die vom Anschlagabschnitt abgewandte Fläche des Dichtungssystems gegen die Montageplatte des elektrischen Steckverbinders.By spraying the sealing system on the abutment portion, the sealing system is firmly connected to the stopper portion and thus provides increased strength and tightness.

In the mounted state, the surface facing away from the abutment portion of the sealing system presses against the mounting plate of the electrical connector.
In einer weiteren bevorzugten Ausführungsform des elektrischen Steckverbinders weist der erste Abschnitt des Dichtungssystems ferner einen umlaufenden Vorsprung auf, der sich zur Montageplatte erstreckt.

Ein umlaufender Vorsprung des ersten Abschnitts des Dichtungssystems, welcher sich zur Montageplatte und/oder zum Anschlagabschnitt erstreckt, sorgt für eine erhöhte Dichtigkeit zwischen Anschlagabschnitt und Montageplatte. Insbesondere kann der Vorsprung aus einem elastischen Material wie z.B. elastischer Kunststoff oder Gummi bestehen, der im montierten Zustand elastisch verformt bzw. zusammengedrückt wird. Aufgrund der dadurch resultierenden Rückstellkraft bzw. des dadurch resultierenden Gegendrucks des elastischen Vorsprungs gegen den Anschlagabschnitt und/oder gegen die Montageplatte kann die Dichtigkeit erhöht werden. Darüber hinaus kann der Vorsprung auch mögliche Unebenheiten des Anschlagabschnitts und/oder der Montageplatte besser ausgleichen, was ebenfalls die Dichtigkeit des Dichtungssystems erhöht.As a circumferential projection of the first portion of the sealing system is understood in the sense of this description, a projection which extends over the entire circumference of the enclosed area of the first portion of the edge. A circumferential projection of the first portion of the sealing system, which extends to the mounting plate and / or the stopper portion, provides for increased tightness between stopper portion and mounting plate. In particular, the projection may consist of an elastic material such as elastic plastic or rubber, which is elastically deformed or compressed in the mounted state. Due to the resulting restoring force or the resulting counter pressure of the elastic projection against the Stop section and / or against the mounting plate, the tightness can be increased. In addition, the projection can also compensate for possible unevenness of the stopper portion and / or the mounting plate better, which also increases the tightness of the sealing system.

The at least one third section of the sealing system preferably connects the at least one sealing ring to the rectangular sealing frame, in the enclosed area of which the at least one sealing ring is arranged.

Bohrungen auf, durch die im montierten Zustand der steckseitige Abschnitt 22 des Verbinderelements 20 hindurchragt.If the sealing system is arranged or sprayed on a board-side surface of the abutment portion, the mounting plate, starting from the abutment portion, offset in the direction of the board-side end of the connector and has openings or holes through which in the assembled state of the board-
Unter einer "formschlüssigen Anordnung" zweier Elemente wird im Rahmen dieser Beschreibung insbesondere verstanden, dass die Elemente abdichtend angeordnet sind.
