- the object of the invention is to provide a cable-plug connection which is suitable for mass production and which can be produced particularly efficiently, does not require a soldered connection and can withstand increased bending and tensile stress.
- the invention with which this object is achieved is characterized in that the two connector sleeves are tubular, lie coaxially one inside the other and are electrically insulated from one another by a cylindrical insulation sleeve, and the connector sleeves together with their tongue each form a single piece of metal, the two tongues being angularly offset from one another and the clip extends at least partially over the insertion area of the tongues, and there is a sprayed-on plastic outer jacket surrounding the clip, the cable end and a partial length of the outer connector sleeve.

- the plug sleeves 2, 3 together with tongues 9 can either be rolled cylindrically from a flat piece of metal or rotated, milled and drilled from rod material.
- the mutual distance between these two tongues 9 is selected so that it corresponds approximately to the center distance of the two wires 10 of the cable 6.
- the two electrically conductive wires 10 are surrounded on the outside in a conventional manner with a flexible, electrically insulating cable sheath 12, which consists of an elastomer, in particular soft plastic.

- a two-part clamp 16 is snugly placed on the cable end area. On the one hand, this prevents the cable sheath 12 from expanding after the tongues 9 are inserted, and on the other hand, this clamp 16 takes up a load in the event of a strong axial pull on the cable 6.

Abstract
Description
Die Erfindung bezieht sich auf eine Kabel-Steckerverbindung mit einem mindestens zweiadrigen, flexiblen Kabel und mindestens zwei Steckerteilen aus elektrisch leitendem Material, die durch eine Isolierschicht elektrisch voneinander getrennt sind, wobei das Kabelende und der Verbindungsbereich der Steckerteile mit den Adern von einem Kunstsotff-Aussenmantel umgeben sind, dass die stromleitende Verbindung zwischen metallischen Steckerhülsen und den Adern des Kabels lötfrei je durch von den Steckerhülsen abragende, zugespitzte, metallische Zungen erfolgt welche je zwischen die elastische Kabelhülle und den metallischen Adern eingreifen, und auf den Kabelendbereich eine das Kabel umschliessende Klammer satt aufgesetzt ist.The invention relates to a cable-plug connection with an at least two-core, flexible cable and at least two plug parts made of electrically conductive material, which are electrically separated from one another by an insulating layer, the cable end and the connection area of the plug parts with the wires of an synthetic outer sheath are surrounded that the current-conducting connection between the metal connector sleeves and the wires of the cable is solderless, each by means of pointed, metallic tongues which protrude from the connector sleeves and which each engage between the elastic cable sleeve and the metal wires, and a clamp enclosing the cable on the cable end area is put on.
Kabel-Steckerverbindungen sind in grosser Zahl bekannt und namentlich in koaxialer Ausführung bei Schwachstrom- oder Kommunikationsgeräten weit verbreitet. Die konventionelle Herstellungsweise enthält eine Lötverbindung zwischen den Steckerhülsen und den elektrischen leitenden Adern. Dies bedingt indessen, dass vor dem Lötvorgang die Isolation um die Adern herum entlang eines Teilstückes entfernt werden muss, um die blanken Drähte mit den Steckerteilen zu verlöten. Bei nahe beieinander liegenden Lötstellen besteht die Gefahr gelegentlicher Kurzschlüsse. Ein weiterer Nachteil ergibt sich dadurch, dass die Verbindung an dem von der Steckerhülse entfernten Teil möglichst flexibel sein muss. Bei hoher Biegebeanspruchung, allenfalls verbunden mit Zugbeanspruchungen, versagen solche Lötverbindungen oftmals.A large number of cable plug connections are known and are particularly widespread in a coaxial version for low-voltage or communication devices. The conventional production method contains a soldered connection between the connector sleeves and the electrically conductive wires. However, this means that the insulation around the wires must be removed along a section before the soldering process in order to solder the bare wires to the connector parts. If the solder joints are close together, there is a risk of occasional short circuits. Another disadvantage arises from the fact that the connection to the part removed from the plug sleeve must be as flexible as possible. Such solder connections often fail at high bending stresses, possibly combined with tensile stresses.
Aus der FR-A-1270636 ist ein elektrischer Stecker mit einem zweiteiligen Gehäuse bekannt, wobei die beiden nebeneinander angeordneten Steckerstifte zur Kontaktgabe je mit einem nadelförmigen Ansatz in den Kabelmantel eingreifen.From FR-A-1270636 an electrical connector with a two-part housing is known, the two connector pins arranged next to one another each engaging in the cable sheath with a needle-shaped extension for making contact.
Damit die Steckerstifte nach der Montage nicht aus dem zweiteiligen Gehäuse herausgezogen werden können, sind sie je mit einem radialen Ansatz versehen, der in je eine Vertiefung des Gehäuses eingreift. Für koaxial ineinanderliegende Steckerhülsen ist eine solche Steckerausbildung nicht anwendbar.So that the connector pins cannot be pulled out of the two-part housing after assembly, they are each provided with a radial projection which engages in a recess in the housing. Such a connector design cannot be used for coaxially nested connector sleeves.
Aus der FR-A-1361157 geht ein Stecker hervor, bei dem drei nebeneinander liegende, flache Schieber vorhanden sind, die mit ihrem ausgeschärften Ende zur Kontaktgabe in ein elektrisches Kabel eingreifen. Das andere Ende ist je mit einer Klemmhülse versehen zum Festklemmen des zuführenden elektrischen Leiters. Auch diese Konstruktion lässt sich nicht auf koaxial ineinander liegende Steckerhülsen übertragen.FR-A-1361157 shows a connector in which there are three flat sliders lying side by side, which with their sharpened end engage in an electrical cable for making contact. The other end is each provided with a clamping sleeve for clamping the supplying electrical conductor. This construction, too, cannot be transferred to plug sleeves lying coaxially one inside the other.
Mit der Erfindung soll die Aufgabe gelöst werden, eine für die Massenproduktion geeignete Kabel-Steckerverbindung zu schaffen, welche besonders rationell herstellbar ist, ohne Lötverbindung auskommt und erhöhte Biege- und Zugbeanspruchung aushält.The object of the invention is to provide a cable-plug connection which is suitable for mass production and which can be produced particularly efficiently, does not require a soldered connection and can withstand increased bending and tensile stress.
Die Erfindung, mit der diese Aufgabe gelöst wird ist dadurch gekennzeichnet, dass beide Steckerhülsen rohrförmig ausgebildet sind, koaxial ineinander liegen und durch eine zylindrische Isolationshülse elektrisch voneinander isoliert sind und die Steckerhülsen je zusammen mit ihrer Zunge ein einziges Metallstück bilden, die beiden Zungen zueinander winkelversetzt sind und die Klammer sich mindestens teilweise über den Einsteckbereich der Zungen erstreckt, und ein die Klammer, das Kabelende und eine Teillänge der äusseren Steckerhülse umgebender, aufgespritzter Kunststoff-Aussenmantel vorhanden ist. Durch die lötfreie Verbindung entfällt der Abisoliervorgang der elektrischen Adern. Da die zugespitzten Zungen der beiden Steckerhülsen zueinander winkelversetzt sind, ergibt sich ein ausreichender Isolationsabstand und zudem ergibt sich dadurch eine Lage der Zungen, die üblicherweise angenähert dem Abstand der beiden elektrischen Leiteradern entspricht. Die auf den Endbereich des Kabels aufgesetzte Klammer bewirkt eine zusätzliche Sicherheit der Kontaktgabe und ergibt eine Sicherung gegen Zugbelastung. Das Ganze ist durch einen umspritzten Aussenmantel aus Kunststoff gegen Oxydationseinflüsse od.dgl. geschützt.The invention with which this object is achieved is characterized in that the two connector sleeves are tubular, lie coaxially one inside the other and are electrically insulated from one another by a cylindrical insulation sleeve, and the connector sleeves together with their tongue each form a single piece of metal, the two tongues being angularly offset from one another and the clip extends at least partially over the insertion area of the tongues, and there is a sprayed-on plastic outer jacket surrounding the clip, the cable end and a partial length of the outer connector sleeve. The stripping process of the electrical wires is eliminated due to the solderless connection. Since the tapered tongues of the two connector sleeves are angularly offset from one another, there is a sufficient insulation distance and, moreover, this results in a position of the tongues which is usually approximately the distance of the two electrical conductor cores. The clip placed on the end area of the cable provides additional contact security and provides protection against tensile loads. The whole is by an overmolded outer jacket made of plastic against the effects of oxidation or the like. protected.

Die nachfolgend anhand der Fig. 1-3 beschriebene Kabel-Steckerverbindung ist zweiadrig ausgeführt. Die beiden an je eine Ader angeschlossenen Steckerhülsen 2, 3 liegen koaxial ineinander und sind durch eine zylindrische Isolierhülse 4 elektrisch getrennt, die vorne in einen Isolier-Ring 5 übergeht. Die Steckerhülsen 2,3, das Kabel 6 und die sich dazwischen befindlichen Anschlussorgane sind von einem aufgespritzten Aussenmantel 7 aus Kunststoff umgeben der als Griffkörper ausgebildet ist. Zur Erhöhung seiner Biegsamkeit sind beidseitig Nuten 8 vorhanden. Jede der beiden metallischen Steckerhülsen 2,3 ist an ihrem hinteren Ende mit einer in Axialrichtung abstehenden, schmalen, zugespitzten Zunge 9 versehen, die mit der jeweiligen Steckerhülse 2,3 ein einziges Stück bildet. Die Steckerhülsen 2,3 samt Zungen 9 können entweder aus einem flachen Metallstück zylindrisch gerollt werden oder aus Stangenmaterial gedreht, gefräst und gebohrt werden. Der gegenseitige Abstand dieser beiden Zungen 9 ist so gewählt, dass er etwa dem Mittenabstand der beiden Adern 10 des Kabels 6 entspricht.The cable connector connection described below with reference to FIGS. 1-3 is designed with two wires. The two plug sleeves 2, 3 connected to one wire each are located coaxially into one another and are electrically separated by a cylindrical insulating sleeve 4, which merges into an insulating ring 5 at the front. The plug sleeves 2, 3, the cable 6 and the connecting elements located between them are surrounded by a sprayed-on outer jacket 7 made of plastic, which is designed as a grip body. Grooves 8 are provided on both sides to increase its flexibility. Each of the two metallic connector sleeves 2, 3 is provided at its rear end with a narrow,
Die beiden elektrisch leitenden Adern 10 sind aussen in üblicher Weise mit einer flexiblen, elektrisch isolierenden Kabelhülle 12 umgeben, die aus einem Elastomer, insbesondere Weichkunststoff besteht. Beide Steckerhülsen 2,3 enthalten an ihrem Mantel Querbohrungen 27 für den Durchtritt von Kunststoff beim Aufspritzen des Aussenmantels 7 und zur Lagesicherung der Steckerhülsen 2,3.The two electrically
Die lötfreie, elektrische Verbindung zwischen den Zungen 9 und den beiden Adern 10 erfolgt in der Weise, dass die zugespitzten Zungen 9 stirnseitig je zwischen elastische Kabelhülle 12 und die Adern 10 eingestossen werden, wie dies aus Fig. 3 und 8 hervorgeht. Die Adern 10 bestehen vorzugsweise aus einer Vielzahl sehr dünner, eine Litze bildende Drähte. Dadurch entsteht ein guter elektrischer Kontakt zwischen den Litzendrähten und den Zungen 9.The solderless, electrical connection between the
Die Elastizität des Kabelmantels 12 bewirkt einen Anpressdruck zwischen den Zungen 9 und den Litzendrähten, sodass sich ein dauernder guter elektrischer Kontakt ergibt. Die Zungen 9 sind mit mehreren, in Axialrichtung verteilt angeordneten Sicken 19 od.dgl. versehen, die der guten Verankerung in der Hülle 12 dienen. Somit ist das sonst übliche Abisolieren des die Litzen 10 umhüllenden Kabelmantels nicht erforderlich. Die Eindringtiefe der Zungen 9 beträgt mindestens die Hälfte, vorzugsweise die ganze axiale Ausdehnung der Klammer 16.The elasticity of the
Nach dem Einsetzen der Zungen 9 in den Kabelmantel 12 wird auf den Kabelendbereich eine zweigeteilte Klammer 16 satt aufgesetzt. Diese verhindert einerseits ein Aufweiten der Kabelhülle 12 nach dem Einsetzen der Zungen 9 und andererseits nimmt diese Klammer 16 eine Belastung auf bei einem allfälligen starken axialen Zug auf das Kabel 6. Eine Spitze 25 der Klammer 16 greift in den Verbindungssteg zwischen die beiden Mantelhüllen 12 ein.After inserting the
Aus den Fig. 4-7 gehen Einzelheiten der zweiteiligen Klammer 16 hervor. Die beiden Klammer-Teilstücke 28,29 werden ineinandergefügt und umschliessen hernach die Kabelhüllen 6 satt. Die beiden Teilstücke 28,29 bestehen je aus einem gegenüber den Kabelhüllen 12 härteren Material, z.B. Hartkunststoff. Der Klammerteil 28 hat einen im wesentlichen U-förmigen Querschnitt mit zwei Schenkeln 11 und einem die Schenkel 11 verbindenden Verbindungsteil 13, der innen zweinebeneinander liegende, bogenförmige Ausnehmungen 14 mit einem dazwischen liegenden, spitzen Mittelstift 25 aufweist. Der Mittelstift 25 durchdringt den Verbindungssteg zwischen den beiden Kabelhüllen 12. Die Klammerschenkel 11 enthalten an ihren freien Enden je eine Schrägfläche 21, um das Aufsetzen des Gegenstückes 28 zu erleichtern.4-7 show details of the two-
Ferner enthalten die Schenkel 11 auf ihrer Innenseite je eine Schulter 23.Furthermore, the
Das auf den Klammerteil 28 aufzusetzende Gegenstück 29 ist beidseitig je mit einer Nut 15 versehen, die der Dicke der Schenkel 11 entspricht. Jede Nut 15 enthält einen Absatz 20. Im Mittelteil sind zweinebeneinander liegende, bogenförmige Ausnehmungen 17 vorhanden. Durch Aufdrücken des Klammerteiles 29 auf die Schenkel 11 werden diese vorerst federnd gespreizt. Der Klammerteil 29 rastet mit seinen Schultern 23 hinter die Absätze 20 ein und kommt gegen die Auflageflächen 18 anzuliegen. Dabei umschliessen die gerundeten Ausnehmungen 14 und 17 das Kabel 6 und üben auf die beiden Kabelhüllen 12 einen radialen Druck aus, sodass die Klammer 16 in Axialrichtung auf dem Kabel fixiert ist.The
Zudem dringt der Mittelstift 25 in das Verbindungs-Material zwischen den Kabelhüllen 12 ein. Hernach wird das Ganze unter Bildung des Aussenmantels 7 durch Kunststoff umspritzt, wie dies aus Fig. 1 hervorgeht. Das flexible Material des Aussenmantels 7 umschliesst die Steckerhülsen 2,3 und das Kabel 6 dicht und zugfest.In addition, the
An Stelle einer Steckerverbindung mit zwei Adern könnten auch drei Adern vorhanden sein mit drei koaxial ineinander liegenden, voneinander elektrisch isolierten Steckerhülsen, von denen zwei unterschiedliche Länge haben und die dritte in einen Steckerstift ausmündet. Alle drei Steckerhülsen sind je mit Zungen 9 versehen, die nebeneinander liegen.Instead of a plug connection with two wires, there could also be three wires with three plug sleeves lying coaxially one inside the other, electrically insulated from one another, two of which have different lengths and the third opens into a plug pin. All three connector sleeves are each provided with
Eine weitere Variante besteht darin, an Stelle von Steckerhülsen zwei übliche zylindrische Steckstifte oder Flachstecker zu verwenden.Another variant is to use two conventional cylindrical plug pins or flat plugs instead of plug sleeves.
