Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Steckverbinders mit einer Mehrzahl von ersten, elektrisch voneinander isolierten Leiterkontakten, die derart aus einem Blech geschnitten werden, dass diese über ein Verbindungsteil des Blechs miteinander verbunden sind, und mit einer Mehrzahl zweiter, miteinander verbundener Leiterkontakte, die aus einem Blech geschnitten werden, wobei die Leiterkontakte zur Ausbildung eines elektrisch isolierenden und die Leiterkontakte zueinander fixierenden Gehäuses teilweise in einen elektrisch isolierenden Werkstoff eingebettet werden und anschließend das Verbindungsteil abgetrennt wird, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a method for producing a connector having a plurality of first, electrically insulated conductor contacts, which are cut from a sheet such that they are interconnected via a connecting part of the sheet, and with a plurality of second, interconnected conductor contacts, the are cut from a metal sheet, wherein the conductor contacts for forming an electrically insulating and the conductor contacts each other fixing housing are partially embedded in an electrically insulating material and then the connecting part is separated, according to the preamble of claim 1.

Derartige Steckverbinder werden in der Regel durch isoliertes Herstellen der einzelnen Leiterkontakte, eines die Leiterkontakte aufnehmenden und voneinander isolierenden Isolators sowie eines die Leiterkontakte und den Isolator aufnehmenden Gehäuses und eine anschließende Montage der Einzelteile produziert. Dabei kann auch vorgesehen sein, dass das Gehäuse, sofern es aus einem elektrisch isolierenden Werkstoff ausgebildet wird, die Funktion des Isolators mit übernimmt.Such connectors are usually produced by isolating the individual conductor contacts, an insulator receiving and insulating the conductor contacts, and a housing accommodating the conductor contacts and the insulator, and a subsequent assembly of the individual parts. It can also be provided that the housing, if it is formed from an electrically insulating material, takes over the function of the insulator.

Diese Form der Herstellung eines Steckverbinders ist insbesondere mit einem erheblichen Montageaufwand verbunden, der die Stückkosten für die einzelnen Steckverbinder erhöht. Da es sich bei Steckverbindern regelmäßig um Massenartikel handelt, für die nur geringe Stückkosten akzeptabel sind, stellt die Kostenreduktion für diese ein wesentliches Entwicklungsziel dar.This form of manufacturing a connector is particularly associated with a considerable installation effort, which increases the unit cost of the individual connectors. Since connectors are usually mass-produced articles, for which only low unit costs are acceptable, cost reduction represents an essential development goal for them.

Aus der US 2004/0092169 A1 ist ein Verfahren zur Herstellung eines Steckverbinders bekannt, bei dem zunächst zwei Gruppen von Signalkontaktelementen, die jeweils endseitig über ein Verbindungsstück in paralleler Ausrichtung gehalten werden, mittels der Verbindungsstücke miteinander verbunden werden. Endkontakte der Signalkontaktelemente werden dann mit Kunststoff umspritzt, um ein erstes Gehäuseteil auszubilden. Daraufhin wird eine Gruppe von Stromkontaktelementen, die endseitig über ein Verbindungsstück in paralleler Ausrichtung gehalten werden, mit einem anderen Kunststoff umspritzt, um ein an das erste Gehäuseteil angeformtes zweites Gehäuseteil auszubilden. Nach den zwei Spritzgießprozessschritten werden alle Verbindungsstücke abgetrennt.From the US 2004/0092169 A1 is a process for making a Connector known in which initially two groups of signal contact elements, which are each held at the ends via a connector in parallel alignment, are connected to each other by means of the connecting pieces. End contacts of the signal contact elements are then encapsulated with plastic to form a first housing part. Then, a group of current contact elements, which are held on the end side via a connector in parallel alignment, overmoulded with another plastic to form a molded onto the first housing part second housing part. After the two Spritzgießprozessschritten all connectors are separated.

Aus der US 6 641 411 B1 ist ein hochgepackter Hochgeschwindigkeitsstecker bekannt, wobei immer jeweils ein Signalleiter von vier Masseleitern umgeben ist. Zur Reduktion von Interferenzen und einem verringerten Übersprechen zwischen zwischen Differentialsignalleitern ist es in einigen Ausführungsformen vorgesehen, dass die Signalleiter derart in dem Stecker angeordnet sind, dass Paare von Differentielsignalen orthogonal zueinander stehen.From the US 6 641 411 B1 is a hochgepackter high-speed connector known, wherein always a signal conductor is surrounded by four ground conductors. In some embodiments, to reduce interference and reduce crosstalk between differential signal conductors, it is contemplated that the signal conductors are disposed in the connector such that pairs of differential signals are orthogonal to each other.

Aus der US 2008/0050969 A1 ist ein Steckverbinder mit einer mehrzahl von parallelen Stiften, welche in dem Steckverbinder befestigt sind, bekannt. Mit dem Steckverbinder ist eine Leiterplatte verbunden. Einige der Stifte sind dazu ausgelegt, Signale aus der Leiterplatte zu übertragen und andere Stifte sind mit einem Massepotential der Leiterplatte elektrisch verbunden. Die Stifte sind derart angeordnet, dass einige Signal leitende Stifte jeweils von vier masse leitenden Stiften umgeben sind.From the US 2008/0050969 A1 is a connector with a plurality of parallel pins, which are mounted in the connector known. A circuit board is connected to the connector. Some of the pins are adapted to transmit signals from the circuit board and other pins are electrically connected to a ground potential of the circuit board. The pins are arranged so that some signal-conducting pins are each surrounded by four ground-conductive pins.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, ein verbessertes und insbesondere kostengünstigeres Verfahren zur Herstellung eines Steckverbinders anzugeben.Based on this prior art, the present invention seeks to provide an improved and more cost-effective method for producing a connector.

Diese Aufgabe wird durch ein Verfahren gemäß dem unabhängigen Patentanspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind Gegenstand der abhängigen Patentansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by a method according to independent claim 1. Advantageous embodiments of the method according to the invention are the subject of the dependent Claims and will become apparent from the following description of the invention.

Bei einem Verfahren der o.g. Art ist es erfindungsgemäß vorgesehen, dass die Mehrzahl zweiter Leiterkontakte eine Leiterkontaktplatte ausbilden und nicht voneinander getrennt werden, wobei die Leiterkontaktplatte über das Verbindungselement mit der Mehrzahl erster Leiterkontakte verbunden sind.In a method of o.g. It is inventively provided that the plurality of second conductor contacts form a conductor contact plate and are not separated from each other, wherein the conductor contact plate are connected via the connecting element with the plurality of first conductor contacts.

Dies hat den Vorteil dass für die Herstellung des Steckverbinders eine Positionierung sämtlicher Leiterkontakte zueinander sichergestellt wird, wobei abschließend durch das Abtrennen des Verbindungsteils nicht nur die ersten Leiterkontakte (insbesondere Signalleiterkontakte) voneinander, sondern auch die zweiten Leiterkontakte (insbesondere Masseleiterkontakte) von den ersten Leiterkontakten getrennt werden und mit diesen somit nicht mehr elektrisch leitend verbunden sind.This has the advantage that for the production of the connector, a positioning of all the conductor contacts to each other is ensured, wherein finally by the separation of the connecting part not only the first conductor contacts (in particular signal conductor contacts) from each other, but also the second conductor contacts (in particular ground conductor contacts) separated from the first conductor contacts are and are therefore no longer electrically connected to these.

Das erfindungsgemäße Verfahren zeichnet sich durch niedrige Stückkosten für die hergestellten Steckverbinder aus, denn sowohl die Herstellung der Einheit aus Leiterkontakten und Verbindungsteil durch Ausschneiden aus einem Blech und vorzugsweise durch Stanzen als auch die Herstellung des Isolators/Gehäuses durch Einbetten in einen elektrisch nicht leitenden Werkstoff und insbesondere Kunststoff, insbesondere mittels Spritzgießen und ähnlicher Verfahren, wie Spritzprägen, etc., stellt jeweils für sich ein für die Massenproduktion kostengünstiges Verfahren dar. Zudem entfällt bei dem erfindungsgemäßen Verfahren weitgehend oder vollständig eine Montage, da die Integration der Leiterkontakte in den Isolator/das Gehäuse im Rahmen von dessen Formgebung erfolgt.The inventive method is characterized by low unit costs for the connectors produced, because both the production of the unit of conductor contacts and connecting part by cutting out of a sheet and preferably by punching and the production of the insulator / housing by embedding in an electrically non-conductive material and In particular, plastic, in particular by means of injection molding and similar processes, such as injection compression, etc., each represents a cost-effective for mass production process. In addition, largely or completely eliminated in the inventive method largely or completely, since the integration of the conductor contacts in the insulator / Housing takes place in the context of its design.

Bei der Mehrzahl erster Leiterkontakte kann es sich beispielsweise um Signalleiterkontakte handeln, die somit - in Verbindung mit einem Signalleiterkontakt eines entsprechenden Gegensteckverbinders - der Signal-übertragenden Verbindung von zwei Signalleitungen (beispielsweise einer Leiterplatte oder eines Kabels, insbesondere Koaxialkabels) sind. Bei der Mehrzahl zweiter Leiterkontakte kann es sich beispielsweise um Massekontakte handeln.The plurality of first conductor contacts may be, for example, signal conductor contacts, which are thus - in conjunction with a signal conductor contact of a corresponding mating connector - the signal-transmitting connection of two signal lines (for example, a printed circuit board or a cable, in particular coaxial cable). The majority of second conductor contacts may be, for example Trade ground contacts.

Demnach ist vorgesehen, zumindest diejenigen Leiterkontakte, die vorzugsweise als Signalleiterkontakte vorgesehen sind, und daher bei der späteren Verwendung des Steckverbinders voneinander isoliert sind, während der Einbettung in den Werkstoff des Gehäuses über den Verbindungsteil zu positionieren.Accordingly, it is provided, at least those conductor contacts, which are preferably provided as signal conductor contacts, and therefore in the later use of the connector are insulated from each other, to position during embedding in the material of the housing via the connecting part.

Der erfindungsgemäße Steckverbinder kann für HF-Anwendungen (HF: Hochfrequenz) vorgesehen sein. Insbesondere kann vorgesehen sein, dass über die ersten Leiterkontakte (identische oder unterschiedliche) HF-Signale übertragen werden sollen. Um die Anforderungen an Steckverbinder für HF-Anwendungen hinsichtlich der Abschirmung der Signalleiter zu erreichen, kann vorgesehen sein, dass die ersten und zweiten Leiterkontakte derart aus dem Blech geschnitten und in das Gehäuse integriert werden, dass ein erster Leiterkontakt jeweils von mehreren und insbesondere von vier (vorzugsweise ein Quadrat ausbildenden) zweiten Leiterkontakten umgeben ist.The connector according to the invention can be provided for HF applications (HF: high frequency). In particular, provision may be made for HF signals to be transmitted via the first conductor contacts (identical or different). In order to meet the requirements for connectors for RF applications with regard to the shielding of the signal conductors, it may be provided that the first and second conductor contacts are cut out of the metal sheet and integrated into the housing in such a way that a first conductor contact in each case consists of several, and in particular four (Preferably, a square forming) second conductor contacts is surrounded.

Zudem kann für eine Eignung des Steckverbinders für HF-Anwendungen auch vorgesehen sein, die Anordnung der Leiterkontakte (insbesondere deren Abstand voneinander) sowie die Wahl des elektrisch isolierenden Werkstoffs (insbesondere auch in Abstimmung mit der den nicht in den Kunststoff eingebetteten Teil des Leiterkontakts umgebenden Luft in ihrer Funktion als Dielektrikum), so zu wählen, dass sich eine für HF-Anwendungen gängige Impedanz (z.B. 50Ω) der Signalleiter bzw. der Einheit aus Signal- und Masseleiter ergibt.In addition, for a suitability of the connector for RF applications also be provided, the arrangement of the conductor contacts (in particular their distance from each other) and the choice of electrically insulating material (especially in coordination with the not embedded in the plastic part of the conductor contact air in their function as a dielectric), so to choose that results in a standard for RF applications impedance (eg 50Ω) of the signal conductor or the unit of signal and ground conductor.

Die Leiterkontakte können vorzugsweise als in eine Aussparung des Gehäuses ragende Kontaktfederlaschen ausgebildet sein, die somit bei einer Verbindung mit einem entsprechenden Leiterkontakt eines Gegensteckverbinders geringfügig deformiert werden und dadurch einen hinreichenden Kontaktdruck erzeugen, der eine sichere Übertragung von insbesondere auch HF-Signalen ermöglicht.The conductor contacts may preferably be formed as projecting into a recess of the housing contact spring tabs, which are thus slightly deformed when connected to a corresponding conductor contact of a mating connector and thereby produce a sufficient contact pressure, which allows a secure transmission of particular RF signals.

In einer weiterhin bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass das Abtrennen des Verbindungsteils in einem definierten Abstand (außenseitig) von dem Gehäuse erfolgt, wodurch Anschlusskontakte ausgebildet werden können, über die die Leiterkontakte des Steckverbinders mit Leitern von beispielsweise einer Platine oder einem oder mehreren (Koaxial-)Kabeln verbunden werden können. Eine solche Verbindung kann insbesondere durch Löten erfolgen, wobei dann der Vorteil realisiert werden kann, dass sich die Lötstellen außerhalb des Gehäuse gut zugänglich befinden, wo sie auf einfache Weise einer Qualitätsüberprüfung unterzogen werden können.In a further preferred embodiment of the method according to the invention can be provided that the separation of the connecting part at a defined distance (outside) of the housing, whereby terminal contacts can be formed, via which the conductor contacts of the connector with conductors of, for example, a board or a or multiple (coaxial) cables can be connected. Such a connection can be made in particular by soldering, in which case the advantage can be realized that the solder joints outside the housing are easily accessible, where they can be easily subjected to a quality inspection.

In einer weiterhin bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass das Gehäuse derart ausgebildet wird, dass dieses Verbindungsmittel zum Verbinden mit (dem Gehäuse von) einem Gegensteckverbinder ausbildet. Die Vorteile der erfindungsgemäßen Ausbildung des Gehäuses durch Umformen und Aushärten eines umformbaren Werkstoffs und insbesondere Spritzgießen eines Kunststoffs kommen dann im besonderen Maße zum Tragen, da ohne zusätzlichen Aufwand auch die Verbindungsmittel hergestellt werden. Die Stückkosten für den erfindungsgemäßen Steckverbinder können so besonders niedrig gehalten werden.In a further preferred embodiment of the method according to the invention can be provided that the housing is formed such that this connecting means for connecting to (the housing of) forms a mating connector. The advantages of the inventive design of the housing by forming and curing a formable material and in particular injection molding of a plastic are then to a particular extent to bear, since without additional effort and the connecting means are produced. The unit cost of the connector according to the invention can be kept very low.

Die Erfindung wird nachfolgend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. In den Zeichnungen zeigen die

Fig. 1 bis 6:
eine bevorzugte Ausführungsform eines mittels eines erfindungsgemäßen Verfahrens hergestellten Steckverbinders.
The invention will be explained in more detail with reference to embodiments shown in the drawings. In the drawings show the
1 to 6:
a preferred embodiment of a connector produced by a method according to the invention.

Die Fig. 1 bis 6 zeigen eine bevorzugte Ausführungsform eines mittels eines erfindungsgemäßen Verfahrens hergestellten Steckverbinders 10 in drei Herstellungsstadien.The Fig. 1 to 6 show a preferred embodiment of a connector 10 produced by a method according to the invention in three stages of manufacture.

In der Fig. 1 (in einer Draufsicht) und der Fig. 2 (in einer isometrischen Ansicht) ist ein metallisches Stanzbauteil dargestellt. Dieses Stanzbauteil bildet insgesamt vier erste Leiterkontakte 1 und insgesamt zehn zweite Leiterkontakte 2 aus. Die ersten Leiterkontakte 1 sollen in dem Steckverbinder der Übertragung von HF-Signalen dienen, während die zweiten Leiterkontakte 2 für einen Anschluss an Masse vorgesehen sind. Die zweiten Leiterkontakte 2 sind als Kontaktfederlaschen ausgebildet und integraler Bestandteil einer Leiterkontaktplatte 3. Alle zweiten Leiterkontakte 2 sind somit elektrisch leitend miteinander verbunden.In the Fig. 1 (in a plan view) and the Fig. 2 (in an isometric View) is shown a metallic stamped component. This stamped component forms a total of four first conductor contacts 1 and a total of ten second conductor contacts 2. The first conductor contacts 1 are to serve in the connector of the transmission of RF signals, while the second conductor contacts 2 are provided for a connection to ground. The second conductor contacts 2 are formed as contact spring tabs and an integral part of a conductor contact plate 3. All second conductor contacts 2 are thus electrically conductively connected to each other.

Die zweiten Leiterkontakte 2 sind über ein Verbindungsteil 4 zudem (auch elektrisch leitend) mit den ersten Leiterkontakten 1 verbunden. Das Verbindungsteil 4 bildet ebenfalls einen integralen Bestandteil des Stanzbauteils aus. Während die ersten Leiterkontakte 1 alle einzeln mit dem Verbindungsteil 4 verbunden sind, erfolgt eine Verbindung zwischen dem Verbindungsteil 4 und der die zweiten Leiterkontakte 2 umfassenden Leiterkontaktplatte 3 über zwei Stege 5.The second conductor contacts 2 are also connected via a connecting part 4 (also electrically conductive) to the first conductor contacts 1. The connecting part 4 also forms an integral part of the stamped component. While the first conductor contacts 1 are all connected individually to the connection part 4, a connection between the connection part 4 and the conductor contact plate 3 comprising the second conductor contacts 2 takes place via two webs 5.

Erfindungsgemäß ist vorgesehen, die Leiterkontakte 1, 2 teilweise mit einem elektrisch isolierenden Kunststoff zu umspritzen, um ein Gehäuse 6 für den Steckverbinder auszubilden, wie dies in der Fig. 3 (in einer Draufsicht) und der Fig. 4 (in einer isometrischen Ansicht) dargestellt ist. Das Gehäuse 6 umgibt sämtliche Leiterkontakte 1, 2 teilweise, wobei jeweils ein Ende jedes der Leiterkontakte 1, 2 in Aussparungen freiliegen, so dass diese Leiterkontakte eines Gegensteckverbinders kontaktieren können. Nicht umspritzt werden der Verbindungsteil 4 sowie sich daran anschließende kurze Abschnitte der ersten Leiterkontakte 1 sowie Abschnitte der das Verbindungsteil 4 mit der Leiterkontaktplatte 3 verbindenden Stege 5.According to the invention, the conductor contacts 1, 2 to be partially encapsulated with an electrically insulating plastic to form a housing 6 for the connector, as shown in the Fig. 3 (in a plan view) and the Fig. 4 (in an isometric view). The housing 6 surrounds all of the conductor contacts 1, 2 partially, wherein in each case one end of each of the conductor contacts 1, 2 exposed in recesses, so that these conductor contacts of a mating connector can contact. The connecting part 4 and adjoining short sections of the first conductor contacts 1 as well as sections of the webs 5 connecting the connecting part 4 to the conductor contact plate 3 are not encapsulated.

Dies ermöglicht, das Verbindungsteil 4 in einem nachfolgenden Verfahrensschritt abzutrennen (vgl. Fig. 5 und 6), wobei das Abtrennen in einem definierten Abstand von dem Rand des Gehäuses 6 erfolgt. Dadurch verbleiben Restabschnitte der ersten Leiterkontakte 1 sowie der Stege 5, von denen einer, einige oder alle als Anschlusskontakte dienen können, um die ersten Leiterkontakte 1 und/oder die Leiterkontaktplatte 3 mit z.B.This makes it possible to separate the connecting part 4 in a subsequent method step (cf. FIGS. 5 and 6 ), wherein the separation takes place at a defined distance from the edge of the housing 6. This leaves residual portions of the first conductor contacts 1 and the webs 5, one of which, some or all can serve as terminal contacts to the first conductor contacts 1 and / or the conductor contact plate 3 with eg

Leiterbahnen einer Platine zu verbinden, beispielsweise zu verlöten.To connect conductor tracks of a board, for example, to solder.

Sowohl die ersten Leiterkontakte 1 als auch die zweiten Leiterkontakte 2 sind, wie sich insbesondere aus den isometrischen Darstellungen gemäß den Fig. 2, 4 und 6 ergibt, als Kontaktfederlaschen mit zweifach abgewinkeltem Verlauf ausgebildet (Die Funktion der ersten Leiterkontakte 1 als Kontaktfederlaschen ergibt sich infolge Ihrer Einbettung in den Kunststoff des Gehäuses). Dieser Verlauf wird durch ein Umbiegen der Leiterkontakte 1, 2 im Rahmen des Stanzprozesses erreicht. Durch die doppelte Umbiegung der Leiterkontakte 1, 2 wird erreicht, dass deren freie Enden in einer Ebene angeordnet sind, die parallel zu der Ebene der nicht umgebogenen Abschnitte des Stanzbauteils liegen. Die freien Enden der Leiterkontakte ragen somit aus dem Gehäuse 6 hervor.Both the first conductor contacts 1 and the second conductor contacts 2 are, as can be seen in particular from the isometric views according to FIGS Fig. 2 . 4 and 6 results, as a contact spring tabs formed with twice angled course (the function of the first conductor contacts 1 as contact spring tabs results from their embedding in the plastic of the housing). This course is achieved by bending the conductor contacts 1, 2 in the context of the stamping process. Due to the double bend of the conductor contacts 1, 2 is achieved that the free ends are arranged in a plane which are parallel to the plane of the non-bent portions of the stamped component. The free ends of the conductor contacts thus protrude from the housing 6.

Das Gehäuse umfasst weiterhin drei Befestigungselemente 7, mit denen der Steckverbinder z.B. auf der Platine befestigt werden kann.The housing further comprises three fastening elements 7, with which the connector e.g. can be mounted on the board.
