Description

Die Erfindung betrifft eine Aderendhülse nach dem Oberbegriff des Anspruchs 1.The invention relates to a wire end sleeve according to the preamble of claim 1.

Stand der Technik:State of the art:

Aderendhülsen der gattungsgemäßen Art sind aus der DE 29 41 770 C2 oder DE 33 14 295 C1 bekannt. Derartige Aderendhülsen dienen zur Herstellung von lötfreien elektrischen Verbindungen, wobei mittels eines Crimp-Werkzeugs das abisolierte Ende eines Leiters mit der Aderendhülse verpreßt bzw. vercrimpt" wird. Ein solches Crimp-Werkzeug ist beispielsweise in der DE 26 14 577 B1 gezeigt.Wire end sleeves of the generic type are known from DE 29 41 770 C2 or DE 33 14 295 C1. Such wire end sleeves are used to produce solderless electrical connections, the stripped end of a conductor being pressed or crimped with the wire end sleeve using a crimping tool. Such a crimping tool is shown, for example, in DE 26 14 577 B1.

Aderendhülsen bestehen aus einem vorderen zylindrischen Metallrohr bzw. einer Metallhülse mit einem daran angespritzten oder aufgesteckten hinteren Kunststoffkragen als Isolierhülse solche Aderendhülsen für den Anschluß eines isolierten Leiters sind aus DE-A- 3610086 bereits bekannt. Der abisolierte Teil des feindrähtigen Leiters wird in die Aderendhülse von hinten in den Kunststoffkragen eingeschoben und im Bereich der Metallhülse verquetscht, wodurch die dauerhafte Verbindung besteht. Der hintere angespritzte Kunststoffkragen nimmt den Leiter mit Isolierung als Isolierhülse auf.Wire end sleeves consist of a front cylindrical metal tube or a metal sleeve with a molded or attached rear plastic collar as an insulating sleeve. Such wire end sleeves for connecting an insulated conductor are already known from DE-A-3610086. The stripped part of the fine-stranded conductor is inserted into the wire end sleeve from behind into the plastic collar and in the area of the metal sleeve squeezed, which creates the permanent connection. The rear molded plastic collar receives the conductor with insulation as an insulating sleeve.

Die verschiedenen Durchmesser bzw. Abmessungen von Aderendhülsen sind in der DIN 46 228 Teil 4 festgelegt. Dabei ist der zylindrische Kunststoffkragen und das vordere zylindrische Metallrohr derart dimensioniert, daß jeweils nur ein Leiter ordnungsgemäß eingeführt und vercrimpt werden kann.The different diameters and dimensions of wire end ferrules are specified in DIN 46 228 Part 4. The cylindrical plastic collar and the front cylindrical metal tube are dimensioned such that only one conductor can be properly inserted and crimped at a time.

Bei der Anbringung von Leitern an Schaltkästen, wie dies beispielsweise in der FR 1 468 859, Fig. 1, gezeigt ist, tritt häufig der Fall ein, daß mehrere Leiter gleichzeitig an eine Schaltklemme angeschraubt werden müssen. Hierfür ist es bekannt, daß zwei Leiter in eine, in irgendeiner Form passende Aderendhülse eingeschoben werden, um gemeinsam an eine Anschlußklemme angebracht zu werden. In diesem Fall wird der Querschnitt des Metallrohrs derart gewählt, daß dieser etwa dem doppelten Leiterquerschnitt der Litzen entspricht, so daß diese eingeführt werden können. Wählt man einen solchen zylindrischen Querschnitt des Metallrohres, so ist der zugehörige zylindrische Kunststoffkragen dieser Aderendhülse derart bemessen, daß er keine zwei nebeneinanderliegende Leiter aufnehmen kann. Er muß deshalb durch mechanische Deformation in eine ovale Form gebracht werden, die in ihren Abmaßen jedoch nicht an nebeneinanderliegende Leiter angepaßt ist. Ein solcher Deformationsvorgang des Kunststoffkragens läßt sich darüber hinaus nur schwer automatisieren.When attaching conductors to switch boxes, as is shown, for example, in FR 1 468 859, FIG. 1, it often occurs that several conductors have to be screwed to a switch terminal at the same time. For this purpose, it is known that two conductors are inserted into a wire end sleeve, which fits in any shape, in order to be jointly attached to a connecting terminal. In this case, the cross section of the metal tube is chosen such that it corresponds approximately to twice the conductor cross section of the strands, so that they can be inserted. If one selects such a cylindrical cross section of the metal tube, the associated cylindrical plastic collar of this wire end sleeve is dimensioned such that it cannot accommodate two conductors lying next to one another. It must therefore be brought into an oval shape by mechanical deformation, but its dimensions are not adapted to adjacent conductors. Such a deformation process of the plastic collar is also difficult to automate.

Wählt man einen Kunststoffkragen mit einem Innendurchmesser, der zwei nebeneinanderliegenden Leitern entspricht, so ist in aller Regel das zugehörige Metallrohr in seinem Querschnitt zu groß bemessen.If you choose a plastic collar with an inner diameter that corresponds to two conductors lying next to each other, the cross section of the associated metal tube is usually too large.

Bei bekannten Aderendhülsen ist es deshalb von Nachteil, daß bei kleinen Schaltgeräten oder Klemmen das Unterklemmen von zwei herkömmlichen Aderendhülsen zum Weiterschleifen der elektrischen Verbindung nicht möglich bzw. nur erschwert möglich ist.In known wire end sleeves, it is therefore disadvantageous that, in the case of small switching devices or terminals, it is not possible or only difficult to clamp two conventional wire end sleeves to loop through the electrical connection.

Vorteile der Erfindung:Advantages of the invention:

Die Aderendhülse gemäß Anspruchs 1 hat demgegenüber den Vorteil, daß diese derart ausgestaltet ist, daß diese zwei Leiter problemlos aufnimmt, ohne eine mechanische Deformation des Kunststoffkragens vornehmen zu müssen. Dabei geht die Erfindung von der Kenntnis aus, daß eine Anpassung der Querschnittsverhältnisse des Metallrohrs bzw. der Metallhülse derart erfolgen muß, daß diese jeweils einen kreiszylindrischen Querschnitt umfaßt, der zwei in sich verdrillte Leiterenden aufnehmen kann, während der sich anschließende Kunststoffkragen in seinem ovalen Querschnitt derart bemessen ist, daß dieser die beiden Leiter nebeneinanderliegend aufnehmen kann. Insofern ist eine geometrische Umgestaltung der Aderendhülsen erforderlich, d. h. der kreiszylindrische Querschnitt des Metallrohrs entspricht weitgehend zweimal dem abisolierten Leiterquerschnitt, während der im Querschnitt ovale Kunststoffkragen zwei nebeneinanderliegende Leiter mit deren Isoliermantel aufnehmen muß.The wire end sleeve according to claim 1 has the advantage that it is designed such that it easily receives two conductors without having to make a mechanical deformation of the plastic collar. The invention is based on the knowledge that the cross-sectional ratios of the metal tube or the metal sleeve must be adjusted such that they each have a circular-cylindrical cross section, which can accommodate two twisted conductor ends, while the adjoining plastic collar has an oval cross section is dimensioned such that it can accommodate the two conductors lying side by side. In this respect, a geometric redesign of the wire end sleeves is required, d. H. the circular cylindrical cross-section of the metal tube largely corresponds twice to the stripped conductor cross-section, while the cross-sectionally oval plastic collar must accommodate two adjacent conductors with their insulating sheath.

Beschreibung der Erfindung:Description of the invention:

Die in den Figuren 1 bis 3 in verschiedener Ansicht dargestellte Aderendhülse 1 besteht aus einem vorderen zylindrischen Metallrohr bzw. einer Metallhülse 2 mit einem vorderen Außendurchmesser d₁ und einem Innendurchmesser d₂. Der zylindrische Teil der Metallhülse 2 erstreckt sich über eine Länge l₁ und öffnet sich dann zu einem kegelförmigen Abschnitt 3 mit einem Kegelwinkel α₁ ≈ 40°. Die Gesamtlänge der Metallhülse 2 ist mit l₂ angegeben. Der Außendurchmesser des kegelförmigen Abschnitts 3 ist mit d₃ bezeichnet.The wire end sleeve 1 shown in Figures 1 to 3 in different views consists of a front cylindrical metal tube or a metal sleeve 2 with a front outer diameter d 1 and an inner diameter d 2. The cylindrical part of the metal sleeve 2 extends over a length l 1 and then opens to a conical section 3 with a cone angle α 1 ≈ 40 °. The total length of the metal sleeve 2 is specified with l₂. The outer diameter of the conical section 3 is denoted by d₃.

Der kegelförmige Abschnitt 3 der Metallhülse 2 ist von einem Kunststoffkragen 4 umspritzt, der einen vorderen kegelförmigen Abschnitt 5 und einen hinteren zylindrischen Abschnitt 6 mit der Länge l₃ aufweist. Die Gesamtlänge des Kunststoffkragens 4 ist mit l₄ angegeben. Der Kunststoffkragen 4 beginnt ab einer Länge l₅ an der Metallhülse 2. Die Gesamtlänge der Aderendhülse ist mit l₆ angegeben.The conical section 3 of the metal sleeve 2 is encapsulated by a plastic collar 4, which has a front conical section 5 and a rear cylindrical section 6 with the length l₃. The total length of the plastic collar 4 is indicated with l₄. The plastic collar 4 starts from a length l₅ on the metal sleeve 2. The total length of the wire end sleeve is indicated with l₆.

In Fig. 1 beträgt der Kegelwinkel des Kunststoffkragens 4 α₂ ≈ 45°. Die Innenmantelfläche 7 des zylindrischen Teils 6 des Kunststoffkragens 4 mit der Länge l₃ verläuft ebenfalls leicht konisch mit einem Konuswinkel von α₃ ≈ 3°. Vorstehende Werte gelten für die Draufsicht der Aderendhülse gemäß Fig. 1.In Fig. 1 the cone angle of the plastic collar is 4 α₂ ≈ 45 °. The inner lateral surface 7 of the cylindrical part 6 of the plastic collar 4 with the length l₃ is also slightly conical with a cone angle of α₃ ≈ 3 °. The above values apply to the top view of the wire end ferrule according to FIG. 1.

In der Seitenansicht der Aderendhülse gemäß Fig. 3 weist der Kunststoffkragen 4 einen vorderen Kegelwinkel α₄ ≈ 20° und einen Innenmantel-Kegelwinkel α₅ ≈ 5° auf. Dabei weist der kegelförmige Abschnitt 3 der Metallhülse 2 den gleichen Kegelwinkel α₅ auf, wie die Innenmantelfläche 7 des Kunststoffkragens 4.In the side view of the wire end ferrule according to FIG. 3, the plastic collar 4 has a front cone angle α₅ ≈ 20 ° and an inner jacket cone angle α₅ ≈ 5 °. The conical section 3 of the metal sleeve 2 has the same cone angle αwinkel as the inner surface 7 of the plastic collar 4th

Wie im Zusammenhang mit den Figuren 1 bis 3 ersichtlich, ist der Kunststoffkragen 4 mit einer ovalen Formgebung versehen, wie dies insbesondere aus Fig. 2 in Draufsicht erkennbar ist. Die breitere Seite des Kunststoffkragens 4 weist eine Außenbreite b₁ und eine Innenbreite b₂ auf. Diese Seite ist mit Bezugszeichen 8 gekennzeichnet. Die schmälere, kreissegmentförmige Seite 9 des Kunststoffkragens 4 weist eine Außenbreite b₃ und eine Innenbreite b₄ auf. Aus der Differenz dieser Breiten ergibt sich die Wandstärke des Kunststoffkragens 4. Die konische Form der Innenmantelfläche 7 des Kunststoffkragens 4 führt nach der Länge l₃ zu einer Innenbreite b₅ als breitere und b₆ als schmälere Innenseitenlänge.As can be seen in connection with FIGS. 1 to 3, the plastic collar 4 is provided with an oval shape, as can be seen in particular in FIG. 2 in a top view. The wider side of the plastic collar 4 has an outer width b 1 and an inner width b 2. This page is identified by reference number 8. The narrower, circular segment-shaped side 9 of the plastic collar 4 has an outer width b₃ and an inner width b₄. From the difference of these widths, the wall thickness of the plastic collar 4 results. The conical shape of the inner circumferential surface 7 of the plastic collar 4 leads, according to the length l 3, to an inside width b₅ as wider and b₆ as narrower inside length.

Wie aus den Figuren 1 bis 3 weiterhin ersichtlich, dient die erfindungsgemäße Aderendhülse 1 zur Aufnahme von zwei Leitern 10, 11, die jeweils eine innere Leiterlitze 12 und einen diese umgebenden Isoliermantel 13 aufweisen. Die Leiter 10, 11 weisen einen Außendurchmesser d₄, die Leiterlitzen 12 einen Außendurchmesser d₅ auf.As can also be seen from FIGS. 1 to 3, the ferrule 1 according to the invention serves to receive two conductors 10, 11, each of which has an inner conductor strand 12 and an insulating jacket 13 surrounding it. The conductors 10, 11 have an outer diameter d₄, the conductor strands 12 have an outer diameter d₅.

Die Aderendhülse 1 ist bezüglich ihrer Metallhülse 2 derart bemessen, daß die Querschnitte der Leiterlitzen 12 beider Leiter 10, 11 nach deren Abisolierung einfach in das Metallrohr 2 einschiebbar sind. Der Innenquerschnitt der Metallhülse 2 muß deshalb wenigstens die Summe der beiden Querschnitte der Leiter 10, 11 betragen.The wire end sleeve 1 is dimensioned with respect to its metal sleeve 2 such that the cross sections of the conductor strands 12 of both conductors 10, 11 can be easily inserted into the metal tube 2 after their stripping. The inner cross section of the metal sleeve 2 must therefore be at least the sum of the two cross sections of the conductors 10, 11.

Gleichermaßen muß die Innenbreite b₂ am Ende des Kunststoffkragens 4 bzw. im vorderen Bereich 14 der Kegelmantelfläche 7, d. h. nach etwa der Länge l₃, derart bemessen sein, daß die beiden Leiter 10, 11 mit ihrem Außendurchmesser d₄ nebeneinanderliegen können. Die Breiten b₂ bzw. b₅ müssen deshalb ungefähr zweimal d₄ betragen (siehe Figuren 1 und 2). Gleiches gilt für die Innenbreite b₆ im vorderen Bereich 15 der Kegelmantelfläche 7 in Fig. 3, die ebenfalls ungefähr dem Außendurchmesser d₄ der Leiter 10, 11 entsprechen muß. Im dargestellten Ausführungsbeispiel ist der Isoliermantel 13 nicht bis zum vordersten Bereich 14, 15 der kegelförmigen Innenmantelfläche (l₃) geschoben, sondern lediglich bis zu einer Länge l₇ eingeschoben. Maßgeblich ist eine ausreichende Einschieblänge des Isoliermantels 13.Similarly, the inner width b₂ at the end of the plastic collar 4 or in the front region 14 of the conical surface 7, d. H. after about the length l₃, be dimensioned such that the two conductors 10, 11 can lie side by side with their outer diameter d₄. The widths b₂ and b₅ must therefore be approximately twice d₄ (see Figures 1 and 2). The same applies to the inner width b₆ in the front region 15 of the conical surface 7 in Fig. 3, which must also correspond approximately to the outer diameter d₄ of the conductors 10, 11. In the illustrated embodiment, the insulating jacket 13 is not pushed up to the foremost region 14, 15 of the conical inner jacket surface (l₃), but only inserted up to a length l₇. A sufficient insertion length of the insulating jacket 13 is decisive.

Durch die Abstimmung der Querschnitte des Kunststoffkragens 4 in Abhängigkeit der einzuführenden und nebeneinanderliegenden Leiter 10, 11 und die Abstimmung des Querschnitts der zugehörigen Metallhülse 2 zur Anpassung an die Querschnitte der beiden einzuschiebenden Leiterlitzen 12 beider Leiter 10, 11, erfolgt eine Anpassung der Aderendhülse an die geometrischen Verhältnisse der zu behandelnden Leiter.By coordinating the cross sections of the plastic collar 4 as a function of the conductors 10, 11 to be inserted and lying next to one another and coordinating the cross section of the associated metal sleeve 2 to adapt to the cross sections of the two conductor strands 12 of both conductors 10, 11 to be inserted, the ferrule is adapted to the geometric relationships of the conductors to be treated.

Die Erfindung ist nicht auf das beschriebene und dargestellte Ausführungsbeispiel beschränkt. Sie umfaßt auch vielmehr alle fachmännischen Weiterbildungen im Rahmen des erfindungsgemäßen Gedankens wie er in den Ansprüchen zum Ausdruck kommt. Anstelle eines ovalen Querschnitts des Kunststoffkragens kann auch ein rechteckförmiger Querschnitt mit kreissegmentförmiger Seitenbegrenzung o. dgl. verwendet werden.The invention is not restricted to the exemplary embodiment described and illustrated. Rather, it also encompasses all professional developments within the scope of the inventive idea as expressed in the claims. Instead of an oval cross-section of the plastic collar, a rectangular cross-section with a circular segment-shaped side boundary or the like can also be used.
