Abstract

The conductor has a solder deposit (3) and an end contact. The solder deposit is attached before the conductor is soldered to a complementary contact. The solder deposit is formed from a sleeve of solderable material, which clinches the end contact. The sleeve preferably has a longitudinal slot and crimps the end contact. An independent claim is included for a method of manufacturing an electrical conductor.

Description

Elektrischer Leiter mit einem Lotdepot an einem Kontaktabschnitt, insbesondere Endabschnitt, wobei das Lotdepot schon an diesem Abschnitt befestigt ist, bevor der Leiter an einen Gegenkontakt angelötet wird.Electric conductor with a solder deposit at a contact section, in particular end portion, wherein the solder deposit already attached to this section, before the ladder is soldered to a mating contact.

Ein derartiger elektrischer Leiter ist z. B. in der DE 100 46 489 C1 beschrieben. An dem Ende eines Metallbandes, das zwischen einer oberen und einer unteren Isolationslage verläuft, befindet sich ein metallisches Krimpstück, dessen Zähne die Lagen zu beiden Seiten des Bandes durchstößt und nach innen gegen die in einem Fenster in der unteren Lage frei liegende Unterseite des Metallbandes gerichtet sind. Nach dem Umschlagen der Zähne wird ein Lotdepot auf die gezahnte Seite des Krimpstückes aufgelötet, so dass das Lot nicht nur die Zähne, sondern auch die frei liegende Seite des Metallbandes benetzt.Such an electrical conductor is z. B. in the DE 100 46 489 C1. At the end of a metal band, that between an upper and a lower insulation layer runs, there is a metallic Krimpstück whose teeth are the layers on both sides of the Bandes pierces and inwards against those in a window in the lower layer exposed underside of the metal strip are directed. After turning the teeth becomes a solder deposit on the toothed side of the crimping piece soldered, so that the solder not only the teeth, but also wets the exposed side of the metal strip.

Zum Verlöten der Leiterbahn wird diese mit dem Lotdepot auf einen Gegenkontakt gelegt, wobei das Krimpstück auf der den Zähnen abgewandten Seite mittels eines Lötkolbens erwärmt wird, was zu einem Schmelzen des Lotes führt. Das nach dem Abkühlen wieder erstarrte Lot verbindet die Leiterbahn mechanisch mit dem Gegenkontakt, wobei gleichzeitig ein elektrisch leitender Kontakt hergestellt ist.For soldering the track, this is with the solder depot placed on a mating contact, wherein the crimping piece on the side facing away from the teeth by means of a soldering iron is heated, resulting in melting of the solder. The after cooling again solidified solder connects the conductor track mechanically with the mating contact, at the same time an electrically conductive contact is made.

Damit das Lotdepot, bevor der Leiter an die Kontaktstelle angelötet wird, schon mit dem elektrischen Leiter verbunden ist, sind somit zwei Schritte auszuführen: Zunächst muss das als Halteelement fungierende Krimpstück mit dem Leiter verbunden werden und dann das Lotdepot angeschmolzen werden, was ziemlich umständlich ist. So that the solder deposit, before the conductor to the contact point is soldered already connected to the electrical conductor is, are thus two steps to perform: first must act as holding element Krimpstück with the Head are connected and then melted the solder deposit which is quite awkward.

Die Erfindung beruht somit auf der Aufgabe, einen elektrischen Leiter gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, der deutlich einfacher herstellbar ist.The invention is thus based on the task of an electrical Ladder according to the preamble of claim 1 create, which is much easier to produce.

Zur Lösung des Problems sieht die Erfindung vor, dass das Lotdepot aus einer aus einem lötfähigen Material bestehenden Hülse gebildet ist, die den Kontaktabschnitt umklammert.To solve the problem, the invention provides that the Lotdepot of one made of a solderable material Sleeve is formed, which clasps the contact portion.

Diese Ausgestaltung hat den Vorteil, dass auf ein gesondertes Halteelement in Form eines Krimpstückes verzichtet werden kann. Des Weiteren wird das Lotdepot nur auf mechanischem Wege am Leiter gehalten. Ein gesonderter Erwärmungsvorgang, mit dem das Lotdepot an den Leiter angelötet wird, ist somit nicht mehr notwendig.This embodiment has the advantage that a separate Retained holding element in the form of a Krimpstückes can be. Furthermore, the solder deposit is only on mechanical Paths kept on the ladder. A separate heating process, soldered the solder deposit to the head is no longer necessary.

Die Hülse kann z. B. auf das Ende eines elektrischen Leiters aufgeschoben und dort gequetscht werden. Am einfachsten ist es aber, wenn die Hülse einen Längsschlitz aufweist und den Kontaktabschnitt in der Art eines Krimpstückes umklammert. Im Gegensatz zum Stand der Technik bildet das Krimpstück dabei das Lotdepot selbst und nicht nur ein Halteelement für das Lotdepot.The sleeve can z. B. on the end of an electrical conductor postponed and squeezed there. The easiest but it is when the sleeve has a longitudinal slot and the contact portion in the manner of a Krimpstückes clutching. In contrast to the prior art The crimping piece forms the solder deposit itself and not only one holding element for the solder depot.

Zum Löten wird ein Flussmittel benötigt, das häufig in Form einer Seele in einem Lötdraht zur Verfügung gestellt wird. Die vorliegende Erfindung sieht vor, dass im Inneren des Hülsenmantels ein Flussmittel vorhanden ist. Die Herstellung des elektrischen Leiters mit einem daran befestigten Lotdepot erfolgt mit den folgenden Schritten:

  • Bereitstellung eines Lötdrahtes mit einer Seele aus einem Flussmittel;
  • Abflachung des Lötdrahtes;
  • Abtrennung eines Teilstückes vom Lötdraht;
  • Verkrimpen des Teilstückes mit dem Kontaktabschnitt.
For soldering, a flux is needed, which is often provided in the form of a soul in a solder wire. The present invention provides that a flux is present in the interior of the sleeve sheath. The production of the electrical conductor with a solder deposit attached thereto is carried out with the following steps:
  • Providing a solder wire with a flux flux;
  • Flattening of the solder wire;
  • Separation of a section from the solder wire;
  • Crimping of the section with the contact section.

Beim letzten Verfahrensschritt wird das Teilstück so ausgerichtet, dass die Seele parallel oder quer zum Leiter verläuft.In the last step, the section is aligned that the soul is parallel or transverse to the ladder runs.

Im ersten Fall gibt es eine Flussmittelaustrittsstelle am Ende des Kontaktabschnittes; im zweiten Fall ist sichergestellt, dass das Flussmittel den Draht vollständig umgibt.In the first case, there is a flux exit point at End of the contact section; in the second case, it is ensured that the flux completely surrounds the wire.

Im Folgenden soll anhand eines Ausführungsbeispiels die Erfindung näher erläutert werden.The following is based on an embodiment of the Invention will be explained in more detail.

Dazu zeigt die einzige Figur einen elektrischen Leiter, bestehend aus einem Kupferdraht 1, der mit einer Isolierung 2 versehen ist. Das Ende des Kupferdrahtes 1 ist abisoliert. Dort wird ein Lotdepot 3 in der Form eines Krimpstückes 4 befestigt. Ein solches Krimpstück 4 besteht aus einem handelsüblichen, typischerweise aus Zinn bestehenden Lötdraht, dessen Seele 5 aus einem Flussmittel besteht. Dieser Lötdraht, der üblicherweise einen runden Querschnitt hat, wird zunächst abgeflacht. Sodann werden davon Plättchen abgetrennt. Diese werden um das abisolierte Ende des Kupferdrahtes 1 geklammert. Dies geschieht in ähnlicher weise, wie ein Krimpstück 4 an einem Leiter befestigt wird: Das Plättchen umschließt den Leiter nahezu vollständig, wobei die aneinanderstoßenden Seiten des Plättchens leicht nach innen gegen den Kupferdraht 1 gedrückt werden. Das Plättchen wird dabei so ausgerichtet, dass die ursprüngliche Seele 5 des Lötdrahtes parallel (wie in der Fig. gezeigt) oder quer zum Kupferdraht 1 verläuft. For this purpose, the only figure shows an electrical conductor, consisting of a copper wire 1, with an insulation 2 is provided. The end of the copper wire 1 is stripped. There is a Lotdepot 3 in the form of a Crimping piece 4 attached. Such Krimpstück 4 is from a commercial, typically tin existing solder wire whose soul 5 from a flux consists. This solder wire, usually a has round cross-section, is first flattened. thereupon are separated from it platelets. These will be around that stripped end of the copper wire 1 stapled. this happens in a similar way, as a Krimpstück 4 at one Ladder is attached: The plate encloses the conductor almost completely, with the abutting ones Sides of the slide gently inward against the copper wire 1 are pressed. The plate is aligned, that the original soul 5 of the solder wire parallel (as shown in the figure) or across the copper wire 1 runs.

Zum Kontaktieren eines Gegenkontaktes wird der elektrische Leiter mit dem mit dem Lotdepot 3 versehenen Ende an die Kontaktstelle gehalten. Ein Lötkolben wird unmittelbar an das aus einem lötfähigen Material, z. B. aus Zinn bzw. einer zinnlegierung, bestehende Lotdepot gesetzt, so dass dieses schmilzt und in üblicher Weise nach dem Abkühlen den Kupferdraht 1 mit dem Gegenkontakt verbindet.To contact a mating contact of the electrical Head with the provided with the solder deposit 3 end held the contact point. A soldering iron becomes instant to that of a solderable material, for. B. of tin or a tin alloy, existing solder deposit set, so that this melts and in the usual way after cooling connects the copper wire 1 with the mating contact.

Die Erfindung hat weiterhin den Vorteil, dass die Größe des Lotdepots relativ leicht dem jeweiligen Einsatzzweck angepasst werden kann. Dazu muss entweder ein dickerer Lötdraht verwendet oder aber ein längeres Plättchen abgeschnitten werden. The invention also has the advantage that the size Lotdepots relatively easy to the respective purpose can be adjusted. This must be either a thicker Solder wire used or cut off a longer plate become.
