Abstract

In a process for fitting a circular cable having a plurality of individual wires with a multi-pole, preferably flat plug into which the individual wires are inserted, the free ends of the individual wires are stripped and fitted with contacts. To allow economical fitting by such a process and greatly reduce the risk of damaging the small contacts, the individual wires are inserted side-by-side into a wire holder of the plug, the ends projecting beyond the wire holder are cut to the same projecting length and stripped over the same length, a contact bearer with the corresponding number of adjacent contacts is secured to the end of the wire holder accepting the individual wires and the opposite regions of stripped individual wires and connectors of the contacts are secured together to provide electrical contact.

Description

Verfahren zum Bestücken eines Kabels mit einem Stecker und hierfür verwendeter Kabelstecker Method of populating a cable with a plug and cable plug used therefor
Beschreibungdescription
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Bestücken eines mit einer Vielzahl von Einzeldrähten versehenen Kabels, vorzugsweise Rundkabels, mit einem mehrpoligen, vorzugsweise flachen Stecker nach dem Oberbegriff des Anspruchs 1 und auf einen bei einem derartigen Verfahren verwendeten Kabelstecker nach dem Oberbegriff des Anspruchs 6.The present invention relates to a method for equipping a cable provided with a multiplicity of individual wires, preferably round cables, with a multipole, preferably flat plug according to the preamble of claim 1 and to a cable plug used in such a method according to the preamble of claim 6 .
Bei einem bekannten Verfahren dieser Art werden die vom Kabelmantel freigelegten Einzeldrähte an ihrem freien Ende abisoliert und dann mit auf einer Rolle angelieferten Kontakten verbunden. Sind die Kontakte mit Crimpanschlüssen versehen, werden die abisolierten Enden der Einzeldrähte auf die Crimpanschlüsse gelegt und mit Hilfe einer Einrichtung (einer Crimpmaschine) angeschlagen. Gleichzeitig werden die Kontakte voneinander getrennt. Die mit den Kontakten versehenen Einzeladern werden dann in einen Stecker eingebracht.In a known method of this type, the individual wires exposed by the cable jacket are stripped at their free ends and then connected to contacts supplied on a roll. If the contacts are provided with crimp connections, the stripped ends of the individual wires are placed on the crimp connections and attached using a device (a crimping machine). At the same time, the contacts are separated. The individual wires provided with the contacts are then inserted into a connector.
Wenn die Stecker und damit die Kontakte kleiner werden, wie es bspw. bei PCMCIA-Kabelsteckern der Fall ist, wird die Verarbeitung sehr schwierig. Außerdem steigt bei kleiner werdenden Teile die Gefahr der Beschädigung der Kontakte. Das Bestücken der Kontakte kann dabei oft dann nur noch unter dem Mikroskop erfolgen, was sehr aufwendig ist. Außerdem muß zur Sicherstellung der Qualität des Produktes ein hoher Aufwand getrieben werden. Da die freien Endbereiche des Kabels schon vor dem Einbringen in den Stecker auf gleiche Länge abgeschnitten werden, muß im Stecker ein Stauraum für die innenliegenden Einzeldrähte vorhanden sein, was wiederum einer erwünschten Miniaturisierung zuwider läuft.If the plugs and thus the contacts become smaller, as is the case with PCMCIA cable plugs, for example, processing becomes very difficult. In addition, as the parts become smaller, the risk of damage to the contacts increases. The contacts can often only be fitted under a microscope, which is very complex. In addition, a lot of effort has to be put into ensuring the quality of the product. Since the free end areas of the cable must be cut to the same length before being inserted into the connector there is a storage space in the plug for the internal individual wires, which in turn runs counter to a desired miniaturization.
Aufgabe der vorliegenden Erfindung ist es deshalb, ein Verfahren zum Bestücken eines Kabels mit einem Stecker der eingangs genannten Art zu schaffen, das in kostengünstigerer Weise durchgeführt werden kann und bei dem die Gefahr der Beschädigungen der kleinen Kontakte stark reduziert ist. Außerdem soll ein entsprechender sehr kleinbauender Kabelstecker bereitgestellt werden.The object of the present invention is therefore to provide a method for equipping a cable with a plug of the type mentioned at the outset, which can be carried out in a more cost-effective manner and in which the risk of damage to the small contacts is greatly reduced. In addition, a corresponding very small-sized cable connector is to be provided.
Zur Lösung dieser Aufgabe sind bei einem Verfahren der eingangs genannten Art die im Anspruch 1 angegebenen Merkmale und bei einem Kabelstecker der genannten Art die im Anspruch 6 angegebenen Merkmale vorgesehen.To achieve this object, the features specified in claim 1 are provided in a method of the type mentioned and the features specified in claim 6 in a cable connector of the type mentioned.
Durch die erfindungsgemäßen Maßnahmen ist es möglich, die Kontakte automatisch und kostengünstig vorzumontieren. Gleichzeitig kann die Kabelvorbereitung zum Anschließen an die einzelnen Kontakte schneller und sicherer durchgeführt werden; dasselbe gilt für die mit Hilfe einer Maschine möglichen Verbindungen von Kabelenden und Kontakten. Die Gefahr der Beschädigung der kleinen Kontakte ist durch deren Vormontage und deren maschinelle Verbindung mit den Einzeldrahtenden auf ein Minimum reduziert. Desweiteren ist die Qualitätsicherung vereinfacht, so daß ein einfach herzustellender und zu montierender Kabelstecker vorgesehen werden kann, der u.a. auch wegen des nicht notwendigen Kabelenden- Stauraumes sehr kleinbauend ist.The measures according to the invention make it possible to pre-assemble the contacts automatically and inexpensively. At the same time, the cable preparation for connection to the individual contacts can be carried out more quickly and safely; the same applies to the connections of cable ends and contacts that can be made using a machine. The risk of damage to the small contacts is reduced to a minimum through their pre-assembly and their mechanical connection to the individual wire ends. Furthermore, the quality assurance is simplified, so that an easy to manufacture and assemble cable connector can be provided, which, among other things. is also very small because of the unnecessary storage space for the cable ends.
Eine weitere Vereinfachung der Kabelvorbereitung ergibt sich dann, wenn die Merkmale gemäß Anspruch 2 vorgesehen sind. Mit den Merkmalen gemäß Anspruch 3 ist erreicht, daß die Abdeckplatte gleichzeitig auch den Kontaktgabebereich abdecken und damit schützen kann.A further simplification of the cable preparation results when the features are provided according to claim 2. With the features according to claim 3 is achieved that the cover plate can also cover the contact area and thus protect.
Die elektrische Kontaktgabe zwischen den abisolierten Einzeldrahtelementen und den Anschlußelementen der Kontakte kann bspw. in einem Arbeitsgang mittels Löten erfolgen. Gemäß einem Ausführungsbeispiel vorliegender Erfindung jedoch sind die Merkmale gemäß Anspruch 4 vorgesehen. Auch das Crimpen kann in vorteilhafter Weise mit Hilfe eines einzigen Werkzeugs in einem Arbeitsgang bei allen Einzeldrähten gleichzeitig erfolgen.The electrical contact between the stripped single-wire elements and the connection elements of the contacts can, for example, be carried out in one operation by means of soldering. According to an embodiment of the present invention, however, the features are provided according to claim 4. Crimping can also advantageously be carried out at the same time for all individual wires with the aid of a single tool.
Mit den Merkmalen gemäß Anspruch 5 ist erreicht, daß die Gefahr des Drahtbruchs stark reduziert ist. Durch die vorhergehenden Maßnahmen ist außerdem sichergestellt, daß die Einzeldrähte beim Umspritzen durch den hohen Spritzdruck nicht weggespült werden.The features of claim 5 ensure that the risk of wire breakage is greatly reduced. The previous measures also ensure that the individual wires are not washed away by the high injection pressure during the encapsulation.
Vorteilhafte Ausgestaltungen des Kabelsteckers ergeben sich aus den Merkmalen eines oder mehrerer der Ansprüche 7 bis 10.Advantageous configurations of the cable connector result from the features of one or more of claims 7 to 10.

Der gemäß einem bevorzugten Ausführungsbeispiel vorliegender Erfindung dargestellte Kabelstecker 10 ist insbesondere in der Ausführung als PCMCIA-Kabelstecker vorgesehen, in der er mit einer Vielzahl von Polen und in sehr kleinbauender Weise ausgebildet ist.The cable connector 10 shown in accordance with a preferred exemplary embodiment of the present invention is provided in particular in the design as a PCMCIA cable connector, in which it is designed with a multiplicity of poles and in a very small size.
Der Kabelstecker 10 besitzt gemäß Figur 1 einen Drahthalter 11, der einstückig aus Kunststoff gefertigt und von seiner Oberseite her offen ist. Der Drahthalter 11 besitzt einen vorderen etwa rechteckförmigen Teil 12 und einen einstückig daran anschließenden hinteren Teil 13, der etwa trapezförmig ausgebildet ist. Im rechteckförmigen Teil 12 ist eine Vielzahl paralleler offener Kanäle 14 vorgesehen. Dabei sind zwei Gruppen 16, 17 mit hier unterschiedlicher Anzahl von Kanälen 14 zu beiden Seiten einer Längsmittelebene 18 vorgesehen. In die Kanäle 14 sind die vom Mantel 21 eines mehradrigen Rundkabels 22 befreiten Endbereiche von Einzeldrähten 19 des Kabels 22 derart eingelegt, daß die freien Enden 23 der Einzeldrähte 19 die Stirn 24 des Drahthalters 11 überragen. Wie der Figur 1 zu entnehmen ist, verlaufen die Einzeldrähte 19 ausgehend vom am hinteren Rand 25 des Drahthalters 11 endenden, mit dem Mantel 21 versehenen Bereich des Kabels 22 strahlenförmig geradlinig durch den trapezförmigen Teil 13 des Drahthalters 11 bevor sie nach einer Biegung in die Kanäle 14 eintauchen. Die Kanäle 14 sind in nicht dargestellter Weise mit nach innen ragenden angeformten Vorsprüngen versehen, zwischen denen die Einzeldrähte 19 klemmend gehalten sind. Der Drahthalter 11 ist in Richtung der Zeichnungsebene sehr schmal, vorzugsweise schmäler als dem Durchmesser des Kabels 22 entspricht.According to FIG. 1, the cable plug 10 has a wire holder 11 which is made in one piece from plastic and is open from the top. The wire holder 11 has a front approximately rectangular part 12 and an integrally connected rear part 13, which is approximately trapezoidal. A multiplicity of parallel open channels 14 are provided in the rectangular part 12. Two groups 16, 17 with a different number of channels 14 are provided on both sides of a longitudinal center plane 18. In the channels 14, the end areas of individual wires 19 of the cable 22 which have been freed from the sheath 21 of a multi-core round cable 22 are inserted such that the free ends 23 of the individual wires 19 protrude beyond the end face 24 of the wire holder 11. As can be seen in FIG. 1, the individual wires 19, starting from the region of the cable 22, which ends at the rear edge 25 of the wire holder 11 and are provided with the jacket 21, run in a straight line through the trapezoidal part 13 of the wire holder 11 before they bend into the channels 14 immerse. The channels 14 are provided in a manner not shown with inwardly projecting projections, between which the Individual wires 19 are held clamped. The wire holder 11 is very narrow in the direction of the drawing plane, preferably narrower than the diameter of the cable 22 corresponds.
Am hinteren Bereich des trapezförmigen Teils 13 übergreift ein Klemmsteg 26 die Einzeldrähte 19 des Kabels 22. Im Bereich der Längsmittelebene 18 ist der Drahthalter 11 mit einer Ausnehmung 27 und einem Rücksprung 28 versehen. Am Grund des Rücksprungs 28 sind zwei federnde Zungen 29 angeformt, die sich zu beiden Seiten der Längsmittelebene 18 erstrecken, weit über die vordere Stirn 24 hinausragen und an einem mittleren Längenbereich und am vorderen Ende mit nach außen stehenden Vorsprüngen 31, 32 bzw. einer Einführungsschräge 33 versehen sind.At the rear area of the trapezoidal part 13, a clamping web 26 engages over the individual wires 19 of the cable 22. In the area of the longitudinal center plane 18, the wire holder 11 is provided with a recess 27 and a recess 28. At the bottom of the recess 28 two resilient tongues 29 are formed, which extend on both sides of the longitudinal center plane 18, protrude far beyond the front forehead 24 and at a middle length range and at the front end with outwardly projecting projections 31, 32 or an insertion slope 33 are provided.
Der Kabelstecker 10 besitzt ferner einen Kontaktträger 36, von dessen Leiste 37 unterseitig zwei länglich rechteckförmige schmale Verbinderstege (Kontakthülsenaufnahmen) 38, 39 zu beiden Seiten der genannten Längsmittelebene 18 abstehen. Die Verbinderstege 38 und 39 sind mit aus Figur 2 ersichtlichen parallelen Längsbohrungen versehen, die durch die Verbinderstege 38, 39 und die Leiste 37 hindurchgehen. In diese Längsbohrungen 41 sind die Kontakthülsen 43 einer Vielzahl von Kontakten 42 eingesetzt, deren Anschlußelemente 44 über die Rückseite der Leiste 37 hinaus abstehen. Wie aus Figur 1B ersichtlich ist, sind den Gruppen 16, 17 der Kanäle 14 im Drahthalter 11 entsprechend Gruppen von eng beieinanderliegenden parallelen Längsbohrungen 41 und entsprechende Gruppen von Kontakten 42 vorgesehen. Beim dargestellten Ausführungsbeispiel sind die Anschlußelemente 44 in Form von Crimpanschlüssen ausgebildet. Die beiden Verbinderstege 38, 39 sind mit jeweils einem einzelnen oder einem Paar von asymmetrisch angeordneten Schienen 46, 47 zum unverwechselbaren Einstecken in bspw. eine IC-Karte versehen. An beiden Enden der Leiste 37 sind parallel zu den Anschlußelementen 44 abstehend Begrenzungsstege 48, 49 vorgesehen. Im Bereich der Längsmittelebene 18 ist ebenfalls nach hinten abstehend an der Leiste 37 eine im Querschnitt rechteckige Muffe 51 angeformt, die über die beiden Zungen 29 rastbar ist.The cable connector 10 also has a contact carrier 36, from the ledge 37 of which underneath two elongated rectangular narrow connector webs (contact sleeve receptacles) 38, 39 protrude on both sides of the longitudinal median plane 18 mentioned. The connector webs 38 and 39 are provided with parallel longitudinal bores shown in FIG. 2, which pass through the connector webs 38, 39 and the strip 37. In these longitudinal bores 41, the contact sleeves 43 of a plurality of contacts 42 are inserted, the connecting elements 44 of which protrude beyond the rear of the strip 37. As can be seen from FIG. 1B, the groups 16, 17 of the channels 14 in the wire holder 11 are provided with groups of closely spaced parallel longitudinal bores 41 and corresponding groups of contacts 42. In the illustrated embodiment, the connection elements 44 are designed in the form of crimp connections. The two connector webs 38, 39 are with each provide a single or a pair of asymmetrically arranged rails 46, 47 for unmistakable insertion into an IC card, for example. Limiting webs 48, 49 projecting parallel to the connecting elements 44 are provided at both ends of the strip 37. In the area of the longitudinal center plane 18, a sleeve 51 with a rectangular cross section is also formed on the ledge 37, which protrudes to the rear and can be latched over the two tongues 29.
Das Bestücken der freien Endbereiche der Einzeldrähte 19 eines Kabels 22 mit dem Kabelstecker 10 geht in folgender Weise vor sich:The free end areas of the individual wires 19 of a cable 22 are populated with the cable connector 10 in the following way:
Die Endbereiche der Einzeldrähte 19 des Kabels 22 werden zunächst über eine bestimmte Länge hinweg vom Mantel 21 befreit. Die Endbereiche der Einzeldrähte 19 werden dann im trapezförmigen Teil 13 geradlinig verlegt und einzeln in die Kanäle 14 eingerastet. Das Einbringen der Einzeldrähte 19 in den Drahthalter 11 wird derart vorgenommen, daß alle freien Enden 23 in einem bestimmten Mindestlängenmaß über die Stirn 24 des Drahthalters 11 überstehen. Die freien Enden 23 werden dann so abgeschnitten, daß sie gemäß Figur 1A in gleichmäßiger Länge über die Stirn 24 hinausragen. Daraufhin werden die freien Enden 23 auf einer bestimmten Länge, vorzugsweise nicht auf der gesamten die Stirn 24 überragenden Längen abisoliert. Dieser Zustand ist in Figur 1A dargestellt.The end regions of the individual wires 19 of the cable 22 are first freed from the sheath 21 over a certain length. The end regions of the individual wires 19 are then laid in a straight line in the trapezoidal part 13 and individually snapped into the channels 14. The introduction of the individual wires 19 into the wire holder 11 is carried out in such a way that all free ends 23 protrude beyond the face 24 of the wire holder 11 to a certain minimum length. The free ends 23 are then cut off so that they protrude in a uniform length over the forehead 24 according to FIG. 1A. The free ends 23 are then stripped to a certain length, preferably not over the entire length that extends beyond the forehead 24. This state is shown in Figure 1A.
Der Kontaktträger 36 ist in der in Figur 1B dargestellten Weise vormontiert. Der Kontaktträger 36 wird mit seiner Muffe 51 über die Zungen 29 geschoben und im hinteren Teil der beiden Zungen 29 verrastet, wie dies Figur 2 zeigt. In diesem Zwischenmontageschritt liegt jeweils ein abisoliertes freies Ende 23 der Einzeldrähte 19 im Anschlußelement 44 eines Kontaktes 42 oder ist diesem unmittelbar benachbart. Mit Hilfe eines einzigen Werkzeuges werden dann die Anschlußelemente 44 derart bearbeitet, daß die abisolierten Drahtenden an die Anschlußelemente 44 der Kontakte 42 angecrimpt werden. Es versteht sich, daß es auch möglich ist, die abisolierten freien Enden 23 der Einzeldrähte 19 mit entsprechend ausgebildeten Anschlußelementen der Kontakte 42 in einem Arbeitsgang zu verlöten.The contact carrier 36 is preassembled in the manner shown in FIG. 1B. The contact carrier 36 is pushed with its sleeve 51 over the tongues 29 and locked in the rear part of the two tongues 29, as shown in FIG. 2. In this intermediate assembly step, a stripped free end 23 of the individual wires 19 lies in the connecting element 44 of a contact 42 or is immediately adjacent to it. With the help of one The connecting elements 44 are then machined such that the stripped wire ends are crimped onto the connecting elements 44 of the contacts 42. It goes without saying that it is also possible to solder the stripped free ends 23 of the individual wires 19 to correspondingly designed connecting elements of the contacts 42 in one operation.
Der Kabelstecker 10 besitzt ferner eine Abdeckplatte 56, die gemäß Figur 2 nach dem Arbeitsgang der Kontaktgabe von abisolierten Einzeldrahtenden 23 und Kontaktanschlußelementen 44 durch Aufrasten auf den Drahthalter 11 befestigt wird. Die Abdeckplatte 56 ist dabei so geformt und so groß, daß sie den Drahthalter 11 vollständig überdeckt und darüber hinaus jenseits der Stirn 24 des Drahthalters 11 die Bereiche der Kontaktgabe zwischen Einzeldrahtenden 23 und Kontaktanschlußelementen 44 im wesentlichen überdeckt, wie dies Figur 2 zeigt. Die Abdeckplatte 56 besitzt eine Ausnehmung 27' und entsprechend dem Drahthalter 11 einen Rücksprung 28'.The cable connector 10 also has a cover plate 56 which, according to FIG. 2, is fastened by snapping onto the wire holder 11 after contacting stripped individual wire ends 23 and contact connection elements 44. The cover plate 56 is shaped and so large that it completely covers the wire holder 11 and beyond the face 24 of the wire holder 11, the areas of contact between the individual wire ends 23 and contact connection elements 44 substantially covers, as shown in Figure 2. The cover plate 56 has a recess 27 'and a recess 28' corresponding to the wire holder 11.
In einem abschließenden Arbeitεgang wird gemäß Figur 3 der so an das Kabel 22 angeschlossene und zusammengebaute Kabelstecker 10 mit Kunststoff umspritzt, so daß sich eine Hülle 57 ergibt, die von der Leiste 37 des Kontaktträgers 36 bis zum Kabel 22 reicht. Die Hülle 57 umgibt dabei den Drahthalter 11, die Abdeckplatte 56 und einen dem Kabelstecker 10 benachbarten Bereich des mit seinem Mantel 21 versehenen Kabels 22. Als Begrenzung für die Hülle 57 zum Kontaktträger 36 hin ist dessen Leiste 37 derart ausgebildet, daß sie den Drahthalter 11 und die Abdeckplatte 56 um die Dicke der zu umspritzenden Hülle 57 rundum überragt. In a final work step, the cable connector 10 connected and assembled in this way to the cable 22 is extrusion-coated with plastic, so that a sheath 57 results which extends from the bar 37 of the contact carrier 36 to the cable 22. The sheath 57 surrounds the wire holder 11, the cover plate 56 and a region of the cable 22 provided with its jacket 21, which is adjacent to the cable connector 10. As a limitation for the sheath 57 towards the contact carrier 36, its strip 37 is designed such that it holds the wire holder 11 and the cover plate 56 extends all around the thickness of the sheath 57 to be encapsulated.
