Definitions
- the invention relates to a cable connector for Transmission of electrical energy, especially for the Transmission of high-frequency signals, with those in the preamble generic features of the main claim.
- the movable current path of the pairing can also be, for example, a two-core or multi-core symmetrical cable.
- the parallel connection of several cables, for example via a connector strip may be required.
- Printed circuit boards with metallization on one and both sides, also in multi-layer arrangement (multilayer), but also spatial configurations, e.g. the concave inner surfaces of an electrical device (molded interconnection devices, MID) are usually used as the carrier material for the fixed current paths, the conductor tracks.
- the plug connections of the known prior art are mostly based on the fact that the conductor tracks are connected to a special socket part which is locked on the circuit board or in the housing wall or is integrated directly into the housing structure.
- the cable is provided with a matching plug part.
- the socket and the plug for HF connections each have their own central conductor section for signal routing.
- the inner conductor part of the socket is connected by soldering to a conductor track and that of the plug to the corresponding conductor of the cable.
- the ground connection is made via the outer conductor parts of the plug and socket, whereby the circuit board is usually connected to the housing or a corresponding chassis that is galvanically connected to the socket via solder connections.
- the socket and the plug of the known prior art must both be designed so that they each meet all the electrical and mechanical requirements placed on the connection.
- the present invention is based on the consideration that many plug connections on circuits of high-frequency technology are only operated very rarely.
- a plug connection is provided primarily to simplify the installation of the circuit, and it is then, during the entire period of use, at most once again detached if, for example, a repair is required.
- it makes sense to look for ways to reduce the hitherto usual effort associated with the use of high-quality socket-plug combinations, regardless of whether these were previously standard parts or special solutions.
- the invention has for its object to build a Plug connection between an electronic circuit and a or more cables with respect to the connection on the circuit carrier as well as to simplify the connector part without the electrical and also the mechanical functions compared to to affect the solutions of the known prior art.
- this is on the cable side Push-in element almost directly into the circuit board and is in direct contact with, without an intermediate link the conductor tracks on the carrier material.
- the structure of the connector is thus on the cable side Component as well as on the request to the designer of the housing reduced, a suitable passage and a releasable lock to provide.
- a series of cable connections can also be advantageous on a circuit, e.g. via a plug connector, realize.
- the effort for the previously required special Bushing construction is also based on the locking function reduced.
- it supports the principle possible space-saving construction the one-sided arrangement preferred by the users all existing connections and incoming and outgoing Cable on a circuit housing.
- the cable-side connector consists of the outer conductor sleeve 7, which is pushed over the outer conductor braid 5 of the cable 2, and the inner conductor sleeve 8, which is pressed onto the inner conductor 6.
- the inner conductor sleeve can also be designed as a pin made of solid material.
- the Inner conductor sleeve 8 over the cheeks 3.1 with the conductor 1.1 and the outer conductor sleeve 7 over the cheeks 3.2 with the conductor tracks 1.2 or the ground plane on the other side of the PCB in Connection.
- the contacting can be coordinated Dimensioning of the sleeves and the distances between them corresponding slot flanks and by spring action of the Sleeve material can be guaranteed.
- Figure 4 finally shows an example of the mechanical Holder of a plug connection according to the Circuit housing 12.
- the passage on the housing 12 is outside with provided a retaining flange 14 through which the lever 15 with hooks grab the connector with the connector housing 13 in the Lock the operating position and also release the bracket allow.
- Embodiments of the invention are described below, in which on the connector housing 13 and the holding flange 14 - can be dispensed with, without compromising on the Quality of locking and mechanical bracket are made have to.
- the holder according to the invention is preferably taken over directly from the circuit board 1 and the sleeve construction of the cable-side plug part.
- undercuts (notches) 16 are provided, or one or two outer flanks 3.2 are not formed in parallel, but are provided with bevels 17. If you now provide resilient projections 16.1 on the outer conductor sleeve 7 or inner conductor sleeve 8 corresponding to the flanks, or form the sleeve with a conical region 17.1 as a counterpart to the bevel 17, then the desired holding effect is achieved without additional components and without special shapes on the board housing.
- the projections 16 can be designed in a manner known per se as circumferential beads, as partial bulges or like hooks, etc., as shown by way of example in FIGS. 5 and 6.
- the hook 16.1 according to FIG. 6 c would also be suitable for an undetachable connection if the undercut 16 is formed on the circuit board 1 accordingly.
- the respective provided with projections 16 or tapered sleeve should slide into the slot arrangement without resistance when the connecting parts are plugged together. This is ensured by the suspension of the sleeve material in connection with the coaxial or helical slots in the sleeve.
- the same effect is achieved in the variant in FIG. 6 c with the spring ring 19 in the constriction (ring groove) 18.
- FIG. 8 shows attached metal tongues 10, in which the outer tongues, which have, for example, a flat rectangular cross section, are provided with lateral undercuts or notches 16.
- the middle tongue could have a cylindrical cross section and be provided with an annular groove as an undercut 16.
- FIGS. 9 and 10 show a plug part with a secondary sleeve 20 shown which e.g. is made of plastic. It surrounds the cable side Plug part in the area of the outer conductor sleeve, and it is conceivable with the connector part on the board, but also how Figure 10 shows to lock on the circuit housing.
- a secondary sleeve 20 shown which e.g. is made of plastic. It surrounds the cable side Plug part in the area of the outer conductor sleeve, and it is conceivable with the connector part on the board, but also how Figure 10 shows to lock on the circuit housing.
- a mostly thin-walled shaped body is produced from a carrier material, for example a housing for electrical components or a housing for a device itself, and the housing is provided on one side - on the inner surfaces - with conductor structures and equipped with components.
- the conventional, flat circuit board is then partially or completely dispensed with.
- the space available for the line connection is usually less favorable or is different than in the case of printed circuit boards which are surrounded by a housing which essentially only takes on the mechanical functions.
- the examples in FIGS. 11 to 14 build, in a continuation of the invention, on an extreme simplification of the contact elements of the plug part.
- the contact elements 7.1, 8.1 each consist of a pin-like part with tabs at both ends.
- One of the tabs each comprises a line-side conductor component 5 or 6 (for example as a crimp connection), and the other is in contact with the contact surface 1.3 or 1.4 on the circuit board 1.0.
- the connection between the contact element and the line-side conductor component can also be made in a form-fitting or material-locking manner by soldering and in a similar manner known per se.
- the connection point on the line is surrounded, for example, by a rubber-elastic mass as molded part 22 (by injection molding or the like).
- the molded part 22 can also perform mechanical tasks of holding and locking the plug connection in a manner known per se, for example in cooperation with corresponding design elements on the circuit board 1.0 (or on a housing).
- the galvanic connection between the contact elements 7.1, 8.1 and the associated contact surfaces 1.3, 1.4 on the circuit carrier 1.0 is ensured by frictional connection.
- the circuit-side tab of the contact element is either bent, for example, in a U-shape and comprises a flank of the slot 3 or the tongue 4.1 on the circuit carrier, or the molded part 22 is additionally designed as a spring and locking element 22.1, 22.2 and encloses the contact area of the plug connection.
- the tab can then, for example, be simply flat (FIG. 11e).
- FIGS. 11a and 11b differ from one another, except in terms of the line type, in that the lateral position stabilization of the contact elements is ensured in the first case exclusively by a sufficiently rigid or resilient design of the rod-like sections of the contact elements 7.1, 8.1; in the other case, the molded body 22 extends into the slot zone and serves as a spring area 22.1 between the contact elements.
- FIGS. 11c to 11e provide information about possible configurations of the contact elements 7.1, 8.1 on the circuit side.
- the spring action with which in each of these examples an intimate clasping and a frictional connection between the surfaces to be contacted can be achieved, is required because the connection must be durable and also secure against shocks and vibrations.
- FIGS. 11a and 11b The functionally essential details of the variants according to FIGS. 11a and 11b return in the examples according to FIGS. 12 to 14 in direct form or modified.
- the orthogonal connection (FIGS. 13 and 14) is particularly interesting for spatial circuit carriers.
- the individual design features are interchangeable. So you can think of the connector according to Figure 12 - for a version with protruding tongue 4.1 - as an orthogonal connection by replacing the circuit-side tongue with a pin that is on the formwork level and is provided with separate contact tracks 1.3, 1.4.
- FIG. 14b - with contact surfaces 1.3, 1.4, for example on an inner wall of the housing - is conceivable for the orthogonal connection according to FIG.
- circuit-side tab of the contact element 7.1, 8.1 for the galvanic connection of conductor tracks of circuit boards printed on both sides, as shown in FIG. 14a.
- a ground connection can be established without through-plating of the circuit carrier being necessary.

Abstract
Description
Die Erfindung betrifft eine Leitungs-Steckverbindung für die Übertragung von elektrischer Energie, insbesondere für die Übertragung von Hochfrequenz-Signalen, mit den im Oberbegriff des Hauptanspruchs angegebenen Gattungsmerkmalen.The invention relates to a cable connector for Transmission of electrical energy, especially for the Transmission of high-frequency signals, with those in the preamble generic features of the main claim.
Bei dem beweglichen Strompfad der Paarung kann es sich neben dem
Koaxialkabel auch z.B. um ein zwei- oder mehradriges symmetrisches
Kabel handeln. Darüber hinaus kann der parallele Anschluß von
mehreren Kabeln, z.B. über eine Steckerleiste, erforderlich sein.
Als Trägermaterial für die festen Strompfade, die Leiterbahnen,
dienen üblicherweise Leiterplatten mit ein- und beidseitiger
Metallisierung, auch in Mehrlagen-Anordnung (Multilayer), aber
auch räumliche Ausbildungen, z.B. die konkaven Gehäuse-Innenflächen
eines Elektrogeräts (moulded interconnection devices, MID).In addition to the coaxial cable, the movable current path of the pairing can also be, for example, a two-core or multi-core symmetrical cable. In addition, the parallel connection of several cables, for example via a connector strip, may be required.
Printed circuit boards with metallization on one and both sides, also in multi-layer arrangement (multilayer), but also spatial configurations, e.g. the concave inner surfaces of an electrical device (molded interconnection devices, MID) are usually used as the carrier material for the fixed current paths, the conductor tracks.
Die Steckverbindungen des bekannten Stands der Technik basieren
meist darauf, daß die Leiterbahnen mit einem speziellen Buchsenteil
verbunden werden, das auf der Leiterplatte oder in der Gehäusewandung
arretiert oder direkt in den Gehäuseaufbau integriert wird.
Das Kabel ist mit einem dazu passenden Steckerteil versehen.
Die Buchse und der Stecker für HF-Verbindungen haben jeweils
ein eigenes zentrisches Leiterstück für die Signalführung.
Das Innenleiterteil der Buchse wird durch Löten mit einer
Leiterbahn und das des Steckers mit dem entsprechenden Leiter
des Kabels verbunden.
Die Masseanbindung wird über die Außenleiterteile von Stecker
und Buchse hergestellt, wobei die Leiterplatte meist über Lötverbindungen
an das mit der Buchse galvanisch verbundene Gehäuse
oder ein entsprechendes Chassis angeschlossen wird.
Die Buchse und der Stecker des bekannten Stands der Technik müssen
beide so ausgebildet sein, daß sie jedes für sich alle an die
Verbindung gestellten elektrischen und mechanischen Anforderungen
erfüllen. The plug connections of the known prior art are mostly based on the fact that the conductor tracks are connected to a special socket part which is locked on the circuit board or in the housing wall or is integrated directly into the housing structure. The cable is provided with a matching plug part.
The socket and the plug for HF connections each have their own central conductor section for signal routing.
The inner conductor part of the socket is connected by soldering to a conductor track and that of the plug to the corresponding conductor of the cable.
The ground connection is made via the outer conductor parts of the plug and socket, whereby the circuit board is usually connected to the housing or a corresponding chassis that is galvanically connected to the socket via solder connections.
The socket and the plug of the known prior art must both be designed so that they each meet all the electrical and mechanical requirements placed on the connection.
Die vorliegende Erfindung geht von der Überlegung aus, daß viele
Steckverbindungen an Schaltungen der Hochfrequenztechnik nur sehr
selten betätigt werden. In vielen Fällen wird eine Steckverbindung
vor allem zur Vereinfachung des Schaltungseinbaus vorgesehen, und
sie wird anschließend, während der gesamten Nutzungdauer, höchstens
dann noch einmal gelöst, wenn z.B. eine Reparatur erforderlich ist.
Hier ist es sinnvoll, Wege zu suchen, um den bisher üblichen, mit
dem Einsatz hochwertiger Buchse-Stecker-Kombinationen verbundenen
Aufwand zu senken, gleich, ob es sich dabei bisher um Normteile
oder um Speziallösungen handelte.The present invention is based on the consideration that many plug connections on circuits of high-frequency technology are only operated very rarely. In many cases, a plug connection is provided primarily to simplify the installation of the circuit, and it is then, during the entire period of use, at most once again detached if, for example, a repair is required.
Here it makes sense to look for ways to reduce the hitherto usual effort associated with the use of high-quality socket-plug combinations, regardless of whether these were previously standard parts or special solutions.
Der Erfindung liegt die Aufgabe zugrunde, den Aufbau einer Steckverbindung zwischen einer elektronischen Schaltung und einem oder mehreren Kabeln in bezug auf den Anschluß am Schaltungsträger wie auch hinsichtlich des Steckerteils zu vereinfachen, ohne die elektrischen und auch die mechanischen Funktionen im Vergleich zu den Lösungen des bekannten Stands der Technik zu beeinträchtigen.The invention has for its object to build a Plug connection between an electronic circuit and a or more cables with respect to the connection on the circuit carrier as well as to simplify the connector part without the electrical and also the mechanical functions compared to to affect the solutions of the known prior art.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen gelöst, die in den kennzeichnenden Teilen des Hauptanspruchs und der Nebenansprüche angegeben sind. Die Unteransprüche enthalten bevorzugte Ausführungsvarianten und -details.According to the invention, this object is achieved with the features those in the characterizing parts of the main claim and the Additional claims are specified. The sub-claims included preferred versions and details.
Bei der erfindungsgemäßen Anordnung wird das kabelseitige Steckelement quasi direkt in die Leiterplatte hineingeschoben und steht, ohne Zwischenglied, in unmittelbarer Verbindung mit den Leiterbahnen auf dem Trägermaterial. Als einzige zusätzliche Funktion bleibt die Halterung des Steckelements am Gehäuse übrig. Der Aufbau der Steckverbindung wird damit auf die kabelseitige Komponente sowie auf die Forderung an den Konstrukteur des Gehäuses reduziert, einen passenden Durchlaß und eine lösbare Sperre vorzusehen. Mit diesem Prinzip kann der Aufwand für die Anschlußstelle - in unterschiedlichen, auf die jeweiligen Betriebsbedingungen abstimmbaren Ausführungsvarianten - wirkungsvoll gesenkt werden. Für Versuchsausführungen wurden Preise errechnet, die nur noch 25% der Werte für vergleichbare Anordnungen des Stands der Technik betragen. In the arrangement according to the invention, this is on the cable side Push-in element almost directly into the circuit board and is in direct contact with, without an intermediate link the conductor tracks on the carrier material. As the only additional Function remains the holder of the plug element on the housing. The structure of the connector is thus on the cable side Component as well as on the request to the designer of the housing reduced, a suitable passage and a releasable lock to provide. With this principle, the effort for the connection point - in different, depending on the respective operating conditions coordinated design variants - effective be lowered. Prices were calculated for test runs, which is only 25% of the values for comparable arrangements of the stand of technology.
Ebenso vorteilhaft läßt sich auch eine Reihung mehrerer Kabelanschlüsse an einer Schaltung, z.B. über eine Steckerleiste, realisieren. Der Aufwand für die bisher erforderliche spezielle Buchsenkonstruktion wird auch hier auf die Arrertierungsfunktion reduziert. Gleichzeitig unterstützt der durch das Prinzip mögliche platzsparende Aufbau die von den Anwendern bevorzugte Einseiten-Anordnung aller vorhandenen Anschlüsse und zu- und wegführenden Kabel an einem Schaltungsgehäuse.A series of cable connections can also be advantageous on a circuit, e.g. via a plug connector, realize. The effort for the previously required special Bushing construction is also based on the locking function reduced. At the same time, it supports the principle possible space-saving construction the one-sided arrangement preferred by the users all existing connections and incoming and outgoing Cable on a circuit housing.

In die Leiterplatte 1 sind bei der Ausführung nach Figur 1 drei

eingefräst oder gestanzt. Die Flanken 3.1, 3.2 der Schlitze sind
partiell metallisiert, und die Metallisierung steht mit unterschiedlichen
Leiterbahnen 1.1, 1.2 oder z.B. einer Massefläche auf
der gegenüberliegenden Seite der Leiterplatte 1 in Verbindung.There are three in the
Der kabelseitige Stecker besteht aus der Außenleiterhülse 7, die
über das Außenleitergeflecht 5 des Kabels 2 geschoben ist, und der
Innenleiterhülse 8, die auf den Innenleiter 6 gepreßt ist.
Die Innenleiterhülse kann für die Variante nach Figur 1 auch als
Stift aus Vollmaterial ausgeführt sein.The cable-side connector consists of the
For the variant according to FIG. 1, the inner conductor sleeve can also be designed as a pin made of solid material.

Ausführungen nach Figur 2 geeignet sein, bei denen eine Zunge von
einer Innenleiterhülse 8 umschlossen wird. Ebenso ist denkbar, auf
gleiche Weise mit einer Zunge-Hülse-Paarung oder der Paarung eines
Schlitzes mit einer Hülse ähnlich der Innenleiterhülse den Kontakt
zum Außen- oder Masseleiter eines Kabels herzustellen, z.B. bei

Wie die Beispiele in Figur 5 bis 7 zeigen, wird die Halterung
erfindungsgemäß vorzugsweise direkt von der Platine 1 und der
Hülsenkonstruktion des kabelseitigen Steckerteils übernommen.
Im Bereich der Schlitze 3 in der Platine 1 werden Hinterschnitte
(Einkerbungen) 16 vorgesehen, oder eine oder zwei äußere Flanken
3.2 werden nicht parallel ausgebildet, sondern mit Schrägen 17
versehen.
Wenn man jetzt an der mit den Flanken jeweils korrespondierenden
Außenleiterhülse 7 oder Innenleiterhülse 8 federnde Vorsprünge 16.1
vorsieht oder die Hülse mit einem kegeligen Bereich 17.1 als
Pendant zur Schräge 17 ausbildet, dann erzielt man den gewünschten
Halterungseffekt ohne zusätzliche Bauteile und ohne spezielle
Ausformungen am Platinengehäuse.
Die Vorsprünge 16 können in an sich bekannter Weise als umlaufende
Sicken, als partielle Ausbeulungen oder hakenähnlich usw.
ausgebildet sein, wie in Figur 5 und 6 beispielhaft gezeigt. Dabei
wäre der Haken 16.1 nach Figur 6 c - bei entsprechender Ausformung
des Hinterschnitts 16 an der Platine 1 - auch für eine unlösbare
Verbindung geeignet.

beim Zusammenstecken der Verbindungsteile widerstandslos in die

in Verbindung mit den koaxialen oder wendelartigen
Schlitzen der Hülse gewährleistet. Der gleiche Effekt wird bei

Bei den im folgenden dargestellten Ausführungsvarianten werden die
Erfordernisse und Spezifika der dreidimensionalen Leiterbahntechnik
besonders berücksichtigt.
Bei der Technik der räumlichen Schaltungsträger wird aus einem
Trägermaterial ein meist dünnwandiger Formkörper hergestellt,
z.B. ein Gehäuse für elektrische Bauteile oder ein Gehäuse für
ein Gerät selbst, und das Gehäuse wird einseitig - an den
Innenflächen - mit Leiterstrukturen versehen und mit Bauelementen
bestückt. Auf die herkömmliche, ebene Leiterplatte wird dann
teilweise bis gänzlich verzichtet.
Bei Anwendung derartiger räumlicher Schaltungsträger sind meist
die Platzverhältnisse für den Leitungsanschluß weniger günstig bzw.
gestalten sich anders als bei Leiterplatten, die von einem Gehäuse
umgeben sind, das im wesentlichen nur die mechanischen Funktionen
übernimmt.The requirements and specifics of three-dimensional interconnect technology are given special consideration in the design variants shown below.
In the technology of spatial circuit carriers, a mostly thin-walled shaped body is produced from a carrier material, for example a housing for electrical components or a housing for a device itself, and the housing is provided on one side - on the inner surfaces - with conductor structures and equipped with components. The conventional, flat circuit board is then partially or completely dispensed with.
When such spatial circuit carriers are used, the space available for the line connection is usually less favorable or is different than in the case of printed circuit boards which are surrounded by a housing which essentially only takes on the mechanical functions.
Die Beispiele in Figur 11 bis 14 bauen, in Weiterführung der
Erfindung, auf einer extremen Vereinfachung der Kontaktelemente
des Steckerteils auf. Die Kontaktelemente 7.1, 8.1 bestehen jedes
aus einem stiftartigen Teil mit Laschen an beiden Enden. Eine der
Laschen umfaßt jeweils eine leitungsseitige Leiterkomponente 5 bzw.
6 (z.B. als Krimpverbindung), und die andere steht mit der Kontaktfläche
1.3 bzw. 1.4 auf dem Schaltungsträger 1.0 in Berührung.
Die Verbindung zwischen dem Kontaktelement und der leitungsseitigen
Leiterkomponente kann auch durch Löten und auf ähnliche, an sich
bekannte Weise form- oder stoffschlüssig erfolgen.
Die Anschlußstelle an der Leitung wird mit einer z.B. gummielastischen
Masse als Formteil 22 umgeben (durch Spritzguß o.ä.).
Das Formteil 22 kann in an sich bekannter Weise gleichzeitig auch
mechanische Aufgaben der Halterung und Arretierung der Steckverbindung
übernehmen, z.B. im Zusammenwirken mit entsprechenden
Gestaltungselementen am Schaltungsträger 1.0 (oder an einem
Gehäuse).
Die galvanische Verbindung zwischen den Kontaktelementen 7.1, 8.1
und den zugehörigen Kontaktflächen 1.3, 1.4 auf dem Schaltungsträger
1.0 wird durch Kraftschluß gewährleistet. Dazu wird die
schaltungsseitige Lasche des Kontaktelements entweder z.B. U-förmig
gebogen und umfaßt eine Flanke des Schlitzes 3 oder der Zunge 4.1
am Schaltungsträger, oder das Formteil 22 ist zusätzlich als Feder- und
Arretierungselement 22.1, 22.2 ausgeführt und umschließt den
Kontaktbereich der Steckverbindung. Dabei kann die Lasche dann z.B.
einfach flächig ausgebildet sein (Figur 11e).The examples in FIGS. 11 to 14 build, in a continuation of the invention, on an extreme simplification of the contact elements of the plug part. The contact elements 7.1, 8.1 each consist of a pin-like part with tabs at both ends. One of the tabs each comprises a line-
The connection between the contact element and the line-side conductor component can also be made in a form-fitting or material-locking manner by soldering and in a similar manner known per se.
The connection point on the line is surrounded, for example, by a rubber-elastic mass as molded part 22 (by injection molding or the like). The molded
The galvanic connection between the contact elements 7.1, 8.1 and the associated contact surfaces 1.3, 1.4 on the circuit carrier 1.0 is ensured by frictional connection. For this purpose, the circuit-side tab of the contact element is either bent, for example, in a U-shape and comprises a flank of the
Die Ausführungsbeispiele nach Figur 11a und 11b unterscheiden sich
- außer durch den Leitungstyp - dadurch voneinander, daß die
seitliche Lagestabilisierung der Kontaktelemente im ersten Fall
ausschließlich über eine ausreichend starre oder eine federnde
Ausführung der stabartigen Abschnitte der Kontaktelemente 7.1, 8.1
sichergestellt wird; im anderen Fall reicht der Formkörper 22 bis
in die Schlitzzone und dient als Federbereich 22.1 zwischen den
Kontaktelementen.
Über mögliche schaltungsseitige Ausbildungen der Kontaktelemente
7.1, 8.1 geben die Figuren 11c bis 11e Auskunft. Die Federwirkung,
mit der bei jedem dieser Beispiele eine innige Umklammerung und
ein Kraftschluß zwischen den zu kontaktierenden Flächen erzielbar
ist, wird gefordert, weil die Verbindung dauerbeständig und auch
gegen Stöße und Vibrationen sicher sein muß.The exemplary embodiments according to FIGS. 11a and 11b differ from one another, except in terms of the line type, in that the lateral position stabilization of the contact elements is ensured in the first case exclusively by a sufficiently rigid or resilient design of the rod-like sections of the contact elements 7.1, 8.1; in the other case, the molded
FIGS. 11c to 11e provide information about possible configurations of the contact elements 7.1, 8.1 on the circuit side. The spring action, with which in each of these examples an intimate clasping and a frictional connection between the surfaces to be contacted can be achieved, is required because the connection must be durable and also secure against shocks and vibrations.
Die funktionswesentlichen Einzelheiten der Varianten nach Figur 11a
und 11b kehren bei den Beispielen nach Figur 12 bis 14 in direkter
Form oder modifiziert wieder. Dabei ist der orthogonale Anschluß
(Figur 13 und Figur 14) besonders für räumliche Schaltungsträger
interessant. Gleichzeitig wird deutlich, daß die einzelnen
Gestaltungsmerkmale austauschbar sind.
So kann man sich die Steckverbindung nach Figur 12 - für eine
Ausführung mit überstehender Zunge 4.1 - auch als orthogonalen
Anschluß denken, indem man die schaltungsseitige Zunge durch einen
Zapfen ersetzt, der auf der Schalungsebene steht und mit getrennten
Kontaktbahnen 1.3, 1.4 versehen ist.
Ebenso ist die Anwendung der Variante nach Figur 14b - mit
Kontaktflächen 1.3, 1.4 z.B. an einer Gehäuse-Innenwand - bei
dem orthogonalen Anschluß nach Figur 13 denkbar, und beide sind
in dieser Form vorteilhaft bei Geräten einzusetzen, bei denen
die Schaltung in 3D-Technik innen an der Wandung vorgesehen ist.
Nicht zuletzt besteht die Möglichkeit, die schaltungsseitige Lasche
des Kontaktelements 7.1, 8.1 auch zur galvanischen Verbindung von
Leiterbahnen von beidseitig bedruckten Schaltungsträgern zu nutzen,
wie in Figur 14a gezeigt. So kann man z.B. eine Masseverbindung
herstellen, ohne daß Durchmetallisierungen des Schaltungsträgers
erforderlich sind.The functionally essential details of the variants according to FIGS. 11a and 11b return in the examples according to FIGS. 12 to 14 in direct form or modified. The orthogonal connection (FIGS. 13 and 14) is particularly interesting for spatial circuit carriers. At the same time, it becomes clear that the individual design features are interchangeable.
So you can think of the connector according to Figure 12 - for a version with protruding tongue 4.1 - as an orthogonal connection by replacing the circuit-side tongue with a pin that is on the formwork level and is provided with separate contact tracks 1.3, 1.4.
Likewise, the use of the variant according to FIG. 14b - with contact surfaces 1.3, 1.4, for example on an inner wall of the housing - is conceivable for the orthogonal connection according to FIG. 13, and both can advantageously be used in this form in devices in which the circuit is in 3D technology is provided on the inside of the wall.
Last but not least, there is the possibility of also using the circuit-side tab of the contact element 7.1, 8.1 for the galvanic connection of conductor tracks of circuit boards printed on both sides, as shown in FIG. 14a. For example, a ground connection can be established without through-plating of the circuit carrier being necessary.
Gerade diese letzten Beispiele machen deutlich, daß die Erfindung vielfältige und unterschiedlichste Ausführungen mit jedem gewünschten Komfortgrad ermöglicht. Dabei ist das der Erfindung zugrunde liegende Prinzip für die Mehrzahl der Anwendungsfälle einfach zu realisieren und gestattet Lösungen mit gegenüber dem bekannten Stand der Technik geringerem konstruktivem und kostenmäßigem Aufwand.These last examples make it clear that the invention diverse and different designs with everyone desired level of comfort. This is the invention underlying principle for the majority of use cases easy to implement and allows solutions with compared to that known prior art less constructive and costly effort.
Bei den Varianten gemäß Figur 11 bis 14 wird nur noch ein Schlitz
bzw. eine Zunge an der Leiterplatte bzw. an einem Gehäuseteil mit
Schaltung benötigt, um eine Steckverbindung mit Kontakten für den
Signalweg und für den Masseanschluß herzustellen.
Das Steckerteil wird dadurch besonders filigran im Aufbau, und das
ist vor allem gleichbedeutend mit einer weiteren Materialeinsparung
und der Verringerung des Platzbedarfs. Darüber hinaus wird ein
unkomplizierter Weg gewiesen, um Steckverbindungen bei einseitig
gedruckten" Schaltungen herzustellen, d.h. es brauchen nicht mehr
die Flanken des Schlitzes bzw. der Zunge metallisiert und mit den
Leiterbahnen der Schaltung verbunden zu werden.
Durch das Prinzip des Anschlusses über beliebig geformte - und
damit auch codierbare - Ausnehmungen im Trägermaterial kann man
mit geringstmöglichem Aufwand Steckverbindungen an beliebigen
Positionen einer Schaltung vorsehen. Es sind Lösungen mit einem
einfachen
Nicht zuletzt können diese Ausführungen der Erfindung auch günstig
als Winkelstecker-Anordnung in vielen Varianten realisiert werden.In the variants according to FIGS. 11 to 14, only a slot or a tongue is required on the printed circuit board or on a housing part with a circuit in order to produce a plug connection with contacts for the signal path and for the ground connection.
This makes the connector part particularly filigree in structure, and this is above all synonymous with further material savings and a reduction in space requirements. In addition, an uncomplicated way is shown to make one-sided connectors to produce printed "circuits, ie it is no longer necessary to metallize the flanks of the slot or the tongue and to connect them to the conductor tracks of the circuit.
Due to the principle of connection via any shape - and thus also codable - recesses in the carrier material, plug connections can be provided at any position of a circuit with the least possible effort. They are solutions with a simple one
Last but not least, these versions of the invention can also be implemented inexpensively as an angle connector arrangement in many variants.
