Abstract

For the solder-free connection of a two-core cable (6) to two plug sleeves (2, 3), which are located coaxially one inside the other and are electrically isolated from one another, said sleeves are provided with axially projecting, narrow, pointed tongues (9). These tongues (9) engage at the ends between the flexible insulation (12) of the cable (6) and the cores (10). The cores (10) are constructed as multiwire braided strands which, together with the tongues (9), result in the electrical contact. A two-piece bracket (16) is fitted snugly onto the cable end. The entire arrangement is extrusion coated with an outer jacket (7) consisting of plastic. <??>This makes possible qualitatively improved, particularly economical mass production of such cable plug connections. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Kabel-Steckerverbindung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a cable plug connection according to the preamble of claim 1.

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 elektrisch 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 in low-voltage or communication devices. The conventional manufacturing 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 connector sleeve must be as flexible as possible. Such solder connections often fail at high bending stresses, at most combined with tensile stresses.

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.

Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches 1 genannten Merkmale gelöst.This object is achieved by the features mentioned in the characterizing part of patent claim 1.

Durch die lötfreie Verbindung entfällt der Abisoliervorgang der elektrischen Adern und durch die auf das Kabel aufgesetzte und mit Kunststoff umspritzte Klammer wird eine solide, zugfeste mechanische Verbindung zwischen dem Kabel und den Steckerhülsen erreicht.The solderless connection eliminates the stripping process of the electrical wires and the clamp, which is placed on the cable and molded with plastic, provides a solid, tensile mechanical connection between the cable and the connector sleeves.

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 each other 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, pointed tongue 9 which projects in the axial direction and forms a single piece with the respective connector sleeve 2, 3. 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.

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 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. Both connector sleeves 2, 3 have transverse bores 27 on their jacket for the passage of plastic when the outer jacket 7 is sprayed on and for securing the connector sleeves 2, 3 in position.

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 tongues 9 and the two cores 10 takes place in such a way that the pointed tongues 9 are each pushed in between the elastic cable sheath 12 and the cores 10, as can be seen from FIGS. 3 and 8. The cores 10 preferably consist of a large number of very thin wires forming a strand. This creates good electrical contact between the stranded wires and the tongues 9.

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 cable sheath 12 causes a contact pressure between the tongues 9 and the stranded wires, so that there is permanent good electrical contact. The tongues 9 are provided with a plurality of beads 19 or the like, which are distributed in the axial direction. provided that serve the good anchoring in the shell 12. Thus, the usual stripping of the cable sheath enveloping the strands 10 is not necessary. The depth of penetration of the tongues 9 is at least half, preferably the entire axial extent of the clip 16.

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 tongues 9 into the cable jacket 12, a two-part clamp 16 is snugly placed on the cable end region. 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. A tip 25 of the clamp 16 engages in the connecting web between the two sheaths 12 .

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-part bracket 16. The two clamp sections 28, 29 are inserted into one another and then surround the cable sheaths 6. The two sections 28, 29 each consist of a material that is harder than the cable sheaths 12, for example hard plastic. The clamp part 28 has an essentially U-shaped cross section with two legs 11 and a connecting part 13 connecting the legs 11, which has arcuate recesses 14 lying inside one another with a pointed center pin 25 in between. The central pin 25 penetrates the connecting web between the two cable sheaths 12. The clip legs 11 each contain an inclined surface 21 at their free ends in order to facilitate the fitting of the counterpart 28.

Ferner enthalten die Schenkel 11 auf ihrer Innenseite je eine Schulter 23.Furthermore, the legs 11 each contain a shoulder 23 on their inside.

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 counterpart 29 to be placed on the clamp part 28 is provided on both sides with a groove 15 which corresponds to the thickness of the legs 11. Each groove 15 contains a shoulder 20. In the central part there are two arcuate recesses 17 lying next to one another. By pressing the clamp part 29 onto the legs 11, these are initially spread apart in a resilient manner. The bracket part 29 engages with its shoulders 23 behind the shoulders 20 and comes to rest against the bearing surfaces 18. The rounded recesses 14 and 17 enclose the cable 6 and exert a radial pressure on the two cable sheaths 12, so that the clamp 16 is fixed on the cable in the axial direction.

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 central pin 25 penetrates the connecting material between the cable sheaths 12. The whole is then encapsulated by plastic, forming the outer jacket 7, as can be seen in FIG. 1. The flexible material of the outer jacket 7 encloses the plug sleeves 2, 3 and the cable 6 in a tight and tensile manner.

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 tongues 9, which are next to each other.

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.
