Description

Die Erfindung betrifft einen Kabelsteckverbinder mit einem Isolationskörper und mit mehreren im Isolationskörper befestigten elektrischen Kontaktbahnen, deren steckseitiges Ende jeweils als Kontaktelement zum Herstellen eines elektrischen Kontaktes mit einem Gegenstecker und deren entgegengesetztes Ende jeweils als Lötanschluß für einen Kabelleiter ausgebildet ist (siehe zum Beispiel FR-A-2 618 614).The invention relates to a cable connector with a Insulation body and with several fastened in the insulation body electrical contact paths, the plug-side end each as a contact element for producing an electrical Contact with a mating connector and their opposite End each formed as a solder connection for a cable conductor (see for example FR-A-2 618 614).

Derartige Steckverbinder sind insbesondere auch im Zusammenhang mit dem von mehreren Computerherstellern angestrebten standardisierten USB(Universal Serial Bus)-Konzept bekannt geworden und von Interesse. Bei diesem neuen Bus-System geht es grundsätzlich darum, die Anschlüsse von Peripheriegeräten an einen PC nicht mehr wie bisher über einzelne, parallele Anschlüsse mit getrennten und oft unterschiedlichen Steckverbindersystemen vorzunehmen, sondern die Peripheriegeräte im wesentlichen seriell an eine gemeinsame Bus-Leitung anzuschließen, die über ein standardisierte Steckbuchse am Gehäuse des PC unmittelbar mit einer Leiterplatte (motherboard) des PC verbunden ist. Das Steckgesicht der Leiterplattensteckbuchse (receptacle) ist im wesentlichen bereits durch eine Spezifikation festgelegt und weist vier in einer Ebene nebeneinander liegende, streifenförmige Kontaktfedern auf, die beim Stecken des Bussteckers (plug) mit den in diesen angeordneten vier nebeneinander liegenden Kontaktschienen bzw. -bahnen zusammenwirken und den elektrischen Kontakt herstellen. Die Kontaktfedern sind im Buchsenstecker in einem Isolationskörper, der im wesentlichen eine Kunststoffzunge mit rechteckigem Querschnitt aufweist, angeordnet und sind in ihrem hinteren Bereich zu nach unten wegstehenden Anschlußbeinchen abgewinkelt, die in Kontaktlöcher der Leiterplatte einsteckbar sind. Stecker und Gegenstecker sind üblicherweise mit einem metallischen Schirmgehäuse versehen. Im Decken- und Bodenbereich dieser Schirmbleche sind jeweils zwei Rasthaken vorgesehen, die in Aussparungen am Schirmgehäuse des passenden Gegensteckers eingreifen und die Haltekräfte beim Ausziehen des plugs und den Erdungskontakt realisieren.Such connectors are particularly related with that sought by several computer manufacturers standardized USB (Universal Serial Bus) concept known become and of interest. This new bus system works it's basically about connecting peripheral devices to a PC no longer as before via individual, parallel Connections with separate and often different connector systems make, but the peripheral devices in essentially to be connected serially to a common bus line, via a standardized socket on the housing the PC directly with a printed circuit board (motherboard) the PC is connected. The mating face of the PCB socket (receptacle) is essentially already through one specification specifies and assigns four in one level adjacent, strip-shaped contact springs, those when the bus connector is plugged in with the ones arranged in it four adjacent contact rails or - Interact with the tracks and establish the electrical contact. The contact springs are in the socket plug in an insulation body, which essentially has a plastic tongue has rectangular cross section, arranged and are in their rear area to connecting legs protruding downwards angled, which can be inserted into contact holes in the circuit board are. Plugs and mating plugs are common provided with a metallic shield housing. In the ceiling and The bottom area of these shield plates are two snap hooks provided that fit in the recesses on the shield housing Mating connector engage and the holding forces when pulling out of the plug and the ground contact.

Die Lötanschlüsse der bisherigen Kabelsteckverbinder sind üblicherweise als flache, vom Isolationskörper frei abstehende Blechelemente ausgebildet, die demnach vom Isolationskörper im wesentlichen nicht berührt bzw. getragen werden. Diese bekannte Lösung ist konstruktiv und wärmetechnisch nicht ohne Nachteile.The solder connections of the previous cable connectors are common as a flat, protruding from the insulation body Sheet metal elements formed, accordingly, from the insulation body are essentially not touched or carried. This well-known Solution is constructive and thermally not without Disadvantage.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, den bekannten Kabelsteckverbinder hinsichtlich der geschilderten Nachteile zu verbessern.The present invention is based on the object known cable connector with respect to the described To improve disadvantages.

Bei einem Kabelsteckverbinder der eingangs genannten Art wird diese Aufgabe dadurch gelöst, daß der Lötanschluß einen V-förmigen Querschnitt aufweist und mit seiner vom Kabelleiter abgewandten Rückseite durch Umspritzen mit Kunststoff im Isolationskörper eingebettet ist.With a cable connector of the type mentioned solved this problem in that the solder connection is a V-shaped Has cross-section and with its from the cable conductor facing away from the back by overmolding with plastic in the insulation body is embedded.

Die Erfindung wird nachfolgend anhand von zwei Ausführungsbeispielen in Zusammenhang mit Figuren näher erläutert.The invention is described below using two exemplary embodiments explained in connection with figures.

Es zeigen:

  • Figur 1 eine perspektivische Teilansicht eines erfindungsgemäßen Kabelsteckverbinders, dessen Lötanschlüsse noch nicht mit Kabelleiter versehen sind,
  • Figur 2 eine Ansicht von der Rückseite her auf noch nicht umspritzte Lötanschlüsse des Kabelsteckverbinders gemäß Figur 1.
    • Show it:
  • 1 shows a perspective partial view of a cable connector according to the invention, the solder connections of which are not yet provided with cable conductors,
  • FIG. 2 shows a view from the rear of solder connections of the cable connector according to FIG. 1 that have not yet been overmolded.

    • In Figur 1 ist ein aus Kunststoffmaterial gespritzter Isolationskörper 1 erkennbar, in dem z. B. vier nebeneinander liegende Kontaktbahnen 2 eingebettet sind (nur drei sind erkennbar). Im unteren Teil der Figur sind die Kontaktelemente der Kontaktbahnen bei der gewählten Darstellung weggelassen worden.In Figure 1 is an injection molded from plastic material 1 recognizable, in which, for. B. four side by side Contact tracks 2 are embedded (only three can be seen). In the lower part of the figure are the contact elements of the Contact paths have been omitted in the selected representation.

    Die V-Form der erfindungsgemäßen Lötanschlüsse geht am besten aus Figur 2 hervor. Die V-Form der Lötanschlüsse hat den Vorteil, daß bezüglich der Kabelleiter, die man sich in Figur 1 von oben und in Figur 2 von unten der Länge nach in die Lötanschlüsse 4 eingelegt denken muß, eine größere Benetzungsfläche beim Löten entsteht. Der Kabelleiter wird praktisch total vom Lötzinn umschlossen. Während des Lötvorganges bedingt die V-Form im übrigen eine vorteilhafte Vorpositionierung des Kabelleiters. Die V-Form ermöglicht weiterhin auch eine leichte Einbettbarkeit bzw. Umspritzbarkeit des Lötanschlusses 4 beim Spritzen des Isolationskörpers 1. Wie am besten aus Figur 1 hervorgeht, ist es ohne weiteres möglich, den Lötanschluß 4 soweit in den Isolationskörper 1 einzubetten, daß die vom Kabelleiter abgewandte Rückseite vollständig vom Kunststoffmaterial umgeben ist. Die Einbettung bringt zum einen eine bessere mechanische Stabilität und Fixierung der Kontaktbahnen 2 im Isolationskörper 1 mit sich. Vor allem aber bedingt die Einbettung einen relativ besseren Wärmeübergang vom Lötanschluß 4 zu seiner Umgebung während des Lötvorganges. Dies ist fertigungstechnisch vorteilhaft, beispielsweise um ein Anschmelzen des Isolationskörpers 1 während des Lötvorganges zu verhindern.The V-shape of the solder connections according to the invention works best from Figure 2. The V-shape of the solder connections has the advantage that with regard to the cable conductors that are shown in FIG from above and in Figure 2 from below lengthways into the Must think soldered connections 4 inserted, a larger wetting area arises during soldering. The cable ladder becomes practical totally enclosed in solder. During the soldering process the V shape also requires advantageous prepositioning of the cable conductor. The V shape still allows easy embedding or encapsulation of the Solder connection 4 when spraying the insulation body 1. How best seen in Figure 1, it is easily possible to embed the solder connection 4 as far as possible in the insulation body 1, that the back facing away from the cable conductor is completely is surrounded by the plastic material. The embedding on the one hand brings better mechanical stability and fixation the contact tracks 2 in the insulation body 1 with itself. Above all, the embedding requires a relatively better one Heat transfer from the solder connection 4 to its surroundings during of the soldering process. This is advantageous in terms of production technology, for example, by melting the insulation body 1 to prevent during the soldering process.

    Es ist vorteilhaft, am kabelseitigen Ende des Lötanschlusses 4 eine abgesetzte Lasche 3 vorzusehen, damit das Kontaktbahnende besonders fest im Kunststoffmaterial verankert ist, so daß auch eine zusätzliche Absicherung gegen ein beispielsweise durch Wärmespannungen während des Lötvorganges bedingtes Verschieben gegeben ist.It is advantageous at the cable end of the solder connection 4 to provide a stepped tab 3 so that the contact track end is particularly firmly anchored in the plastic material, so that additional protection against, for example due to thermal stresses during the soldering process Moving is given.
