Abstract

A multi-wire flexible electrical lead which is intended for the power supply of small electrical equipment and is provided with a plug or a plug socket at the end of the lead, is to be better matched to the electrical and mechanical requirements. For this purpose, with a maximum conductor cross-section of each wire of 0.5 mm<2>, it is provided that tension-resistant threads on a plastic base be arranged in the filler spaces of the wires which are twisted or are arranged parallel to one another, and that the ends of these threads be fixed to the bridge between the pins of the plug or of the plug socket. For this purpose, the electrical properties of the conductor have been separated from the tensile strength of the lead and optimal matching has been facilitated. <IMAGE>

Description

Die Erfindung liegt auf dem Gebiet der flexiblen elektrischen Leitungen, wie sie zur Stromversorgung von elektrischen Kleingeräten verwendet werden, und ist bei der konstruktiven Ausgestaltung solcher Leitungen im Hinblick auf bessere Gebrauchseigenschaften anzuwenden.The invention is in the field of flexible electrical lines, such as are used for the power supply of small electrical devices, and is applicable to the design of such lines with a view to better performance properties.

Elektrische Kleingeräte, insbesondere Handgeräte, wie Rasierapparate und Zahnbürsten, werden mittels mehradriger flexibler elektrischer Leitungen an das Stromnetz angeschlossen, wobei diese Leitungen wenigstens an einem Ende mit einem Stecker zum Einführen in eine Steckdose versehen sind. Das andere Ende kann eine Steckbuchse zum Anschluß der Leitung an das Kleingerät aufweisen (beispielsweise bei Rasierapparaten üblich) oder direkt in das Kleingerät eingeführt sein (beispielsweise bei Zahnbürsten üblich). Stecker und Steckbuchse sind in aller Regel konfektioniert ausgeführt, d. h. am Leitungsende angespritzt. Dabei sind die Steckerstifte oder die Buchsenelemente in einer Stiftbrücke fixiert Bei den für elektrische Kleingeräte verwendeten Anschlußleitungen handelt es sich entweder 'um Zwillings- oder Drillingsleitungen mit feinstdrähtigem Kupferleiter oder um zwei- oder dreiadrige Kunststoff- oder Gummischlauchleitungen. Bei derartigen Leitungen, deren Adern einen Leiterquerschnitt von wenigstens 0,75 mm2 aufweisen, übernehmen die Leiter sowohl eine elektrische als auch eine mechanische (Zugfestigkeit) Funktion. Die mechanische Funktion ist jedoch wegen des geringen Leiterquerschnittes begrenzt (Sammelliste "i" der Siemens AG, "Isolierte Starkstromleitungen", Band 1, Teil 1, 1974, Seiten 17 bis 19).Small electrical devices, in particular hand-held devices, such as shavers and toothbrushes, are connected to the power supply by means of multi-core flexible electrical lines, these lines being provided at least at one end with a plug for insertion into a socket. The other end can have a socket for connecting the line to the small device (for example, common for shavers) or inserted directly into the small device (for example, common for toothbrushes). Plugs and sockets are usually made up, that is molded on at the end of the cable. The connector pins or the socket elements are fixed in a pin bridge The connecting cables used for small electrical devices are either ' twin or triple cables with fine-stranded copper conductors or two- or three-core plastic or rubber hose lines. In cables of this type, whose cores have a conductor cross section of at least 0.75 mm 2 , the conductors perform both an electrical and a mechanical (tensile strength) function. However, the mechanical function is limited because of the small conductor cross section (collection list "i" from Siemens AG, "Insulated Power Cables", Volume 1, Part 1, 1974, pages 17 to 19).

Zur Verbesserung der Zugfestigkeit und damit der mechanischen Beanspruchbarkeit flexibler elektrischer Leitungen ist es bekannt, den Kupferleiter mechanisch dadurch zu verstärken, daß die Leiterdrähte auf ein Tragorgan aus Baumwolle, Kunststoff oder Glasfasern aufgesponnen werden. Bei derartigen Leitern, sogenannten Lahnlitzenleitern, sind die elektrische und die mechanische Funktion weitestgehend getrennt. Solche Leiter sind jedoch bei der Montage von Steckern schwieriger zu handhaben als normale Litzenleiter (US-PS 29 00 437).To improve the tensile strength and thus the mechanical load-bearing flexible electrical lines, it is known to reinforce the copper conductor mechanically in that the L e iterdrähte to a supporting member made of cotton, plastic or glass fibers are spun. In such conductors, so-called Lahnlitzeleitern, the electrical and mechanical function are largely separated. However, such conductors are more difficult to handle when assembling plugs than normal stranded conductors (US Pat. No. 2,900,437).

Ausgehend von einer zwei- oder dreiadrigen flexiblen elektrischen Leitung mit Litzenleitern und Kunststoffmantel und mit einem als Stecker oder Steckbuchse ausgebildeten Leitungsende zur Stromversorgung von elektrischen Kleingeräten, wobei der Stecker oder die Steckbuchse eine Stiftbrücke aufweist, liegt der Erfindung die Aufgabe zugrunde, eine solche Leitung durch Trennung der elektrischen Funktion "Stromleitung" von der mechanischen Funktion "Zugfestigkeit" besser an die elektrischen und mechanischen Anforderungen anzupassen.Starting from a two- or three-wire flexible electrical line with stranded conductors and plastic sheath and with a line end designed as a plug or socket for the power supply of small electrical devices, the plug or socket having a pin bridge, the invention is based on the object of such a line Separation of the electrical function "power line" from the mechanical function "tensile strength" better adapted to the electrical and mechanical requirements.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß bei einem Leiterquerschnitt jeder Ader von höchstens 0,5 mm2 in einem oder mehreren Zwickelräumen der verseilten oder parallel nebeneinander angeordneten Adern zugfeste Fäden auf Kunststoffbasis angeordnet sind und daß die Enden dieser Fäden an der Stiftbrücke des Steckers oder der Steckbuchse fixiert sind.To solve this problem it is provided according to the invention that with a conductor cross-section each wire of at most 0.5 mm 2 in one or more gusset spaces stranded or parallel juxtaposed wires tensile threads are arranged on a plastic basis and that the ends of these threads are fixed to the pin bridge of the plug or the socket.

Bei einer derart ausgebildeten Leitung ist der elektrische Querschnitt ausschließlich nach elektrischen Gesichtspunkten festgelegt, so daß gegenüber herkömmlichen Leitungen eine Materialersparnis und damit auch eine Verringerung in den Außenabmessungen erzielt wird. Die mechanische Funktion "Zugfestigkeit" wird von zugfesten Fäden übernommen, die in den Zwickelräumen der Adern angeordnet sind und damit nicht wieder zu einer Vergrößerung der Außenabmessung der Leitung führen. Die Leitung weist demnach geringe Außenabmessungen auf und ist besonders leicht. Durch die vorgesehene Verankerung der zugfesten Fäden an der Stiftbrücke ist darüber hinaus der mechanisch besonders gefährdete Übergang Leitung/ Stecker bzw. Leitung/Steckbuchse mechanisch gesichert. Im Zuge der Leitung wird die notwendige Zugfestigkeit durch Reibungsschluß der zugfesten Fäden mit den Adern und dem Kunststoffmantel sichergestellt.In the case of a line designed in this way, the electrical cross section is determined exclusively from an electrical point of view, so that a material saving and thus a reduction in the outer dimensions is achieved compared to conventional lines. The mechanical function "tensile strength" is carried out by tensile threads which are arranged in the gusset spaces of the wires and thus do not lead to an increase in the external dimension of the line again. The line therefore has small external dimensions and is particularly light. The intended anchoring of the tension-resistant threads on the pin bridge also mechanically protects the mechanically particularly endangered line / plug or line / socket transition. In the course of the line, the necessary tensile strength is ensured by the frictional connection of the tensile threads with the wires and the plastic sheath.

Ausführungsbeispiele der neuen Leitung sind in den Fig. 1 bis 5 dargestellt. Dabei zeigen die Fig. 1 bis 4 Querschnittsbilder verschiedener Leitungstypen und Fig. 5 ein mit einem Stecker versehenes. Leitungsende.Exemplary embodiments of the new line are shown in FIGS. 1 to 5. 1 to 4 show cross-sectional images of different line types and FIG. 5 shows a connector provided with a connector. Line end.

Bei den in den Fig. 1 bis 4 dargestellten Leitungen handelt es sich um zwei- bzw. dreiadrige Leitungen in verseilter und damit runder.Ausführung (Fig. 1 und 2) bzw. in unverseilter und damit flacher Ausführung (Fig. 3 und 4). Die Leitungen können außerdem gewendelt ausgeführt sein. Jede Leitung besteht aus den Adern 1 und 2 bzw. 3, dem Kunststoffmantel 6 bzw. 7 bzw. 8 bzw. 9 und den in den Zwickelräumen der Adern angeordneten zugfesten Fäden 1'0 auf Kunststoffbasis. Jede Ader weist dabei einen feindrähtigen oder feinstdrähtigen Kupferleiter 4 mit einem Querschnitt von etwa 0,2 mm2 und eine extrudierte Kunststoffisolierung 5 auf.The lines shown in FIGS. 1 to 4 are two-wire or three-wire lines in a stranded and thus round version (FIGS. 1 and 2) or in a non-stranded and thus flat version (FIGS. 3 and 4). . The lines can also be coiled. Each line consists of the wires 1 and 2 or 3, the plastic sheath 6 or 7 or 8 or 9 and the tensile threads 1 ' 0 arranged in the gusset spaces of the wires on a plastic basis. Each wire has a fine wire or fine-wire copper conductor 4 with a cross section of about 0.2 mm 2 and an extruded plastic insulation 5.

Bei den zugfesten Fäden 10, die jeweils nicht in allen Zwickelräumen angeordnet zu sein brauchen, handelt es sich vorzugsweise um solche auf der Basis eines Polyamides, wie sie im Handel unter der Bezeichnung "Kevlar" erhältlich sind.The tensile threads 10, which need not be arranged in all gusset spaces, are preferably those based on a polyamide, as are commercially available under the name "Kevlar".

Fig. 5 zeigt das mit einem Stecker versehene Ende einer zweiadrigen runden Anschlußleitung, wobei die Adern 1 und 2 an die in einer Stiftbrücke 11 verankerten Steckerstifte 12 und 13 angeschlossen sind. Das Gehäuse 14 besteht aus einem angespritzten Kunststoffteil und umfaßt die Steckerbrücke einschließlich des Leitungsendes mit dem Kunststoffmantel 6.5 shows the end of a two-wire round connecting line provided with a connector, the wires 1 and 2 being connected to the connector pins 12 and 13 anchored in a pin bridge 11. The housing 14 consists of an injection-molded plastic part and comprises the plug bridge including the cable end with the plastic jacket 6.

Zwischen den beiden Steckerstiften 12 und 13 ist an der Stiftbrücke 11 der nach innen ragende Haken 15 angeordnet, an dem die Enden der zugfesten Fäden 10 fixiert sind. Diese Fixierung kann beispielsweise durch eine Verknotung von jeweils zwei Fäden oder auch durch eine Verknotung eines Einzelfadens erfolgen. Es besteht aber auch die Möglichkeit, die Enden mehrerer Fäden miteinander zu verschweißen und die dadurch gebildete Schlaufe über den Haken 15 zu legen. Es ist weiterhin denkbar, die zugfesten Fäden mittels einer oder mehrerer kabelschuhartiger Hülsen an dem Haken 15 zu fixieren. Alternativ können die zugfesten Fäden auch durch Quetschung in einer mit der Stiftbrücke fest verbundenen metallischen Hülse fixiert oder ihre Enden können mit der Stiftbrücke verklebt oder an der Stiftbrücke festgeklemmt sein. Wesentlich ist in jedem Fall, daß die Fixierung (Abfangung) der Fäden unabhängig von der Fixierung (Kontaktierung) der Leiter erfolgt.Arranged between the two connector pins 12 and 13 on the pin bridge 11 is the inwardly projecting hook 15, on which the ends of the tension-resistant threads 10 are fixed. This fixation can take place, for example, by knotting two threads in each case or also by knotting a single thread. But there is also the possibility of welding the ends of several threads together and placing the loop formed thereby over the hook 15. It is also conceivable to fix the tensile threads to the hook 15 by means of one or more cable lug-like sleeves. Alternatively, the tension-resistant threads can also be fixed by squeezing in a metallic sleeve which is firmly connected to the pin bridge, or their ends can be glued to the pin bridge or clamped to the pin bridge. It is essential in any case that the threads are fixed (caught) independently of the fixing (contacting) of the conductors.
