Description
Verbindungselement für elektrische "Kab'eT '* ***Connecting element for electrical "Kab'eT '* ***
Um ein versehentlich durchtrenntes Kabel zu flicken oder aber durch aneinanderfügen zweier kürzerer Kabel ein längeres zu erhalten, ist es bisher üblich, die einzelnen Adern abzuisolieren, den elektrischen Kontakt durch Lüsterklemmen herzustellen und das Ganze mit Isolierband zu umwickeln, um es halbwegs vor eindringender Nässe und den Benutzer vor einem Stromschlag zu schützen. Auch eine wirksame Zugentlastung ist so nicht erreichbar.In order to repair a cable that has been accidentally severed or to create a longer one by joining two shorter cables together, it is currently common practice to strip the individual wires, establish electrical contact using terminal blocks and wrap the whole thing with insulating tape to protect it somewhat from moisture and the user from electric shock. Effective strain relief is also not achievable in this way.
Die Schneid-Klemm- oder Crimp-Technik kommen bisher in vielen Anwendungen in der Elektronik, insbesondere der Nachrichtentechnik und Datenübertragung zum Einsatz, beispielsweise bei Computerleitungen, oder auch in der Autoelektrik, benötigen aber, im Gegensatz zu der Erfindung, fast immer ein spezielles Werkzeug wie etwa eine Quetschverbinderzange, um die elektrische Verbindung herzustellen.The insulation displacement or crimping technology has so far been used in many applications in electronics, especially in communications technology and data transmission, for example in computer cables, or in car electrics, but, in contrast to the invention, almost always requires a special tool such as a crimp connector pliers to make the electrical connection.
Problem:Problem:
Die bisherigen Methoden haben einige Nachteile: Sie sind meist zeitaufwendig, da mehrere Arbeitsschritte nötig sind. Das Resultat ist oft nicht sehr haltbar (das Isolierband löst sich leicht wieder, die Drähte reißen aus den Lüsterklemmen), und es ist kein definierter Schutz gegen Berührung (z.B. nach IP-Schutzklassen) spannungsführender Teile gegeben, es gibt keine Zugentlastung der Kabel und es sind mehrere Komponenten {Lüsterklemmen, Isolierband, eventuell eine Abzweigdose) und /oder spezielles Werkzeug wie etwa eine Quetschverbinderzange erforderlich. Zudem sind die sonst üblichen Gehäuse aufgrund ihrer Bauform nicht geeignet um z.B. zusammen mit dem reparierten Kabel auf eine Kabeltrommel aufgewickelt zu werden.The previous methods have some disadvantages: They are usually time-consuming because several work steps are necessary. The result is often not very durable (the insulating tape comes off easily, the wires tear out of the terminal blocks), and there is no defined protection against contact (e.g. according to IP protection classes) of live parts, there is no strain relief for the cables and several components (terminal blocks, insulating tape, possibly a junction box) and/or special tools such as crimp connector pliers are required. In addition, the otherwise usual housings are not suitable due to their design for being wound onto a cable drum together with the repaired cable, for example.

Lösung:Solution:
Diese Probleme werden mit den im Schutzanspruch aufgeführten Merkmalen gelöst.These problems are solved with the features listed in the protection claim.
Mit der Erfindung wird erreicht, daß das Verbinden von Kabeln schnell und sicher geschieht:The invention ensures that cables can be connected quickly and safely:
-einfaches Einlegen der freien Kabeladern,-easy insertion of the free cable wires,
-kein Abisolieren der Adern mehr,--no more stripping of the wires,-
-die Verbindung ist insgesamt sehr haltbar und-the connection is overall very durable and

Das Gehäuse ist aus zwei identischen Hälften aufgebaut. Dies erlaubt eine besonders kostengünstige Fertigung und vermeidet Verwechslungen bei der Montage. Die Erfindung erlaubt eine besonders schlanke Bauform. Damit ist es z.B. möglich ein repariertes oder verlängertes Kabel zusammen mit dem Verbindungselement auf eine Kabeltrommel zu wickelnThe housing is made up of two identical halves. This allows for particularly cost-effective production and avoids confusion during assembly. The invention allows for a particularly slim design. This makes it possible, for example, to wind a repaired or extended cable together with the connecting element onto a cable drum

Das der Länge nach geteilte, aus zwei identischen Hälften bestehende Gehäuse (Fig.l), ist durch eine spezielle Ausformung in der Lage, die zur elektrischen Verbindung notwendigen Schneid-Klemmkontakte aufzunehmen und zu fixieren. Die Verbindung der Adern zweier Kabel (Fig. 1, 2a und 2b) erfolgt durch Einlegen in die dafür vorgesehenen Schneid-Klemmkontakte (Fig.l, 3). Der elektrische Kontakt wird beim Schließen des Gehäuses durch Einschneiden der dafür ausgeformten Metallkontakte in die Isolierung der Drähte hergestellt. Die Dimensionen der Gehäusehälften und der Schneid-Klemmkontakte sind so aufeinander abgestimmt, dajS der elektrische Kontakt sicher und mit ausreichendem Übergangswiderstand hergestellt wird. Die Gehäusehälften werden z.B. mit Schrauben verbunden, um den nötigen Druck für die Zugentlastung (Fig.l, 5) und das gleichmäßige Einschneiden der Isolierungen aufzubringen und den gängigen Sicherheitsvorschriften zu entsprechen. Das Gehäuse darüberhinaus ist mit einer umlaufenden Dichtung (Fig.l, 4) versehen, die Spritzwasser zuverlässig abhält.The housing, which is split lengthwise and consists of two identical halves (Fig. 1), is specially shaped to accommodate and fix the insulation displacement contacts required for electrical connection. The connection of the wires of two cables (Fig. 1, 2a and 2b) is made by inserting them into the insulation displacement contacts provided for this purpose (Fig. 1, 3). The electrical contact is made when the housing is closed by cutting the specially shaped metal contacts into the insulation of the wires. The dimensions of the housing halves and the insulation displacement contacts are coordinated so that the electrical contact is made safely and with sufficient contact resistance. The housing halves are connected with screws, for example, in order to apply the necessary pressure for strain relief (Fig. 1, 5) and to cut the insulation evenly and to comply with current safety regulations. The housing is also provided with a circumferential seal (Fig.l, 4) which reliably keeps out splash water.
Die teilweise abgeflachte AujBenkontur des Gehäuses erlaubt das Aufbringen eines Firmenlogos, z.B. durch Siebdruck.The partially flattened outer contour of the housing allows the application of a company logo, e.g. by screen printing.
