Definitions
- the invention relates to a plug for moisture-proof electrical connectors according to the preamble of claim 1.
- connection has additional sealing elements.
- substantial improvements in moisture protection could be achieved.
- the connection itself is insufficiently secured so that the seals of the plug connection do not function properly or if the cable is damaged, it can also lead to defects in the plug.
- plugs which are intended to be exposed to moisture in particular in the underwater area, there is often the problem that incoming moisture is led into the plug by the capillary action along the individual electrical lines or is forwarded in the plug and causes irreparable damage there or in the connected devices ,
- the DE 100 54 714 A1 relates to the sealing of a cable in a cable duct, in which cables are guided partially insulated in cable ducts and at least partially surrounded by a compressible elastomeric sealing element.
- the improved sealing effect is intended to take place by means of a compression of the sealing element taking place in the production process.
- such seals do not always have the required longitudinal water-tightness.
- the invention is therefore based on the object to improve a plug with respect to its protective properties against moisture.
- a plug having the features of claim 1.
- the individual electrical lines which are sheathed within a connector cable each with individual insulation, partially stripped and not only at their ends where the connection, in particular soldering done with the contact elements, but also in an area beyond that at Completion of the plug is surrounded by potting compound.
- the potting compound completely covers the bare wires and seals them reliably.
- the encapsulation with potting compound then acts as a capillary barrier. So that the stripped areas can not touch each other during the production of the plug and can lead to short circuits, according to the invention at least one electrically non-conductive spacer is used, which spaces the stripped areas apart from each other.
- the spacer is then arranged between two stripped and surrounded by potting compound portions.
- the non-conductive spacer in the finished plug is also surrounded by the potting compound and is fixed and held by this.
- the cable sheath is usually partially removed and then at the ends of the individual electrical lines their respective insulation. Under stripped areas in the context of the invention, however, not only those areas of the electrical lines are to be understood in which a previously existing insulation was removed, but also those that were possibly made from the outset without isolation, ie insulation.
- the spacer is not directly connected to the housing of the plug.
- a connection to the housing exclusively via the potting compound and / or the cable or the electrical lines themselves. This simplifies the production of the plug, and yet the cured electrical potting compound and the spacer are immovably fixed in the housing.
- the spacer is formed by remaining insulation sections. These are arranged between the line ends, which are electrically connected to the contact elements, and the stripped and later encapsulated with encapsulant area, which serves the longitudinal water-tightness.
- the spacer may be advantageous to arrange at least one spreading element between the stripped areas and the cable sheath, ie the outer insulation of the cable, which prevents contact between the lines in the stripped areas. This may be necessary because a certain minimum length of stripping is required to secure the longitudinal water-tightness.
- the leads are very thin or soft and therefore too flexible, it may possibly come in contact with the connector despite the spacer in the stripped area.
- the expansion element can be formed, for example, by shrink tubing pieces drawn onto the individual lines.
- so-called power lines with usually only two data lines and larger cross-section usually> 0.5 mm 2
- the insulation of the individual electrical lines are usually thick enough to touch the individual Exclude cables or strands, so that a further expansion element is usually not necessary.
- the in Fig. 1 shown plug has a connector housing 1, in the front side of a contact carrier 2 is inserted.
- the front of the plug is provided with a profile seal 3.
- contact elements 4 are held, which are connected via contact pins 5 conductively connected to electrical lines 6.
- the electrical lines 6 each have a sheathing insulation 7 and are summarized in the further course by a cable sheath in a cable 8.
- the cable 8 extends at the rear end out of the connector housing 1, which is closed there with a seal 9.
- the individual electrical lines 6 between the electrical connection with the contact elements 4 and the merger in the cable 8 each have an insulation-free or stripped area 6 ', which is surrounded in each case by the interior of the plug housing 1 filling potting compound 10. So that the stripped regions 6 'of the electrical leads 6 do not come into contact with the assembly of the plug, according to the invention between the stripped areas 6 'and the electrically conductive connections with the contact elements 4, here via the contact pins 5, a spacer arranged. This is formed in the illustrated embodiment by remaining insulation sections 7 ', which complain about the electrical lines 6 in this area from each other. Preferably, these insulation sections 7 'and the spacer is stabilizing also surrounded by potting compound 10. In front of the insulating sections 7 ', there is in each case a further stripped-down partial area 6 ", which is likewise surrounded by potting compound 10 in order to further improve the seal.
- the stripped regions 6 'behind the spacer 7' should have at least a length L of 3 mm, preferably even at least 5 mm in length.
- this length L should not be greater than 20 mm, preferably even not more than 10 mm.
- the stripped regions 6 ' may nevertheless come into contact, as long as they are not yet surrounded by the potting compound 10.
- at least one additional expansion element This should preferably be arranged in the transition region between the stripped region 6 'and the sheathing insulation 7. It may also surround the sheathing insulation 7 prior to being gathered in the cable 8.
- This expansion element may preferably be formed by spreader elements 12 mounted on the individual lines 6, as shown in FIG Fig. 2 is shown.
- the Spreizelement conductede 12 are preferably shrink tubing pieces. So cause the Spreizelement conductede 12 as it were a Thickening of the insulation 7 and thereby a further spacing of the stripped regions 6 'from each other.
- the plug according to the invention has an excellent longitudinal water-tightness and is therefore very safe even in underwater use. This improved tightness is structurally simple and without significantly increased costs in the inventive manner.

Description
Die Erfindung betrifft einen Stecker für feuchtigkeitsgeschützte elektrische Steckverbindungen nach dem Oberbegriff des Anspruchs 1.The invention relates to a plug for moisture-proof electrical connectors according to the preamble of
Aus der
Die
Der Erfindung liegt daher die Aufgabe zugrunde, einen Stecker hinsichtlich seiner Schutzeigenschaften gegen Feuchtigkeit zu verbessern.The invention is therefore based on the object to improve a plug with respect to its protective properties against moisture.
Diese Aufgabe wird durch einen Stecker mit den Merkmalen des Anspruchs 1 gelöst. Dabei werden die einzelnen elektrischen Leitungen, die innerhalb eines Steckerkabels jeweils mit einzelnen Isolierungen ummantelt sind, bereichsweise abisoliert und zwar nicht nur an ihren Enden, an denen die Verbindung, insbesondere Verlötung mit den Kontaktelementen erfolgt, sondern auch in einem darüber hinausgehenden Bereich, der bei Fertigstellung des Steckers mit Vergussmasse umgeben ist. Beim Vergießprozess (unter Vakuum) legt sich die Vergussmasse komplett um die blanken Drähte und versiegelt diese zuverlässig. Die Ummantelung mit Vergussmasse wirkt sodann als Kapillarsperre. Damit die abisolierten Bereiche sich auch bei der Fertigung des Steckers nicht berühren und zu Kurzschlüssen führen können, wird erfindungsgemäß zumindest ein elektrisch nicht leitender Abstandhalter eingesetzt, der die abisolierten Bereiche voneinander beabstandet. Zusätzlich zu den abisolierten und von Vergussmasse umgebenen Teilbereichen auf der den Kontaktelementen abgewandten Seite des Abstandhalters sind vor dem Abstandhalter, d.h. zwischen den Kontaktelementen und dem Abstandhalter ebenfalls abisolierte Teilbereiche vorhanden sein, die ebenfalls von Vergussmasse umgeben sind. Dies erhöht die Längswasserdichtigkeit noch weiter. Der Abstandhalter ist dann zwischen zwei abisolierten und von Vergussmasse umgebenen Teilbereichen angeordnet. Vorzugsweise ist der nicht leitende Abstandhalter im fertigen Stecker ebenfalls von der Vergussmasse umgeben und wird durch diese fixiert und gehalten.This object is achieved by a plug having the features of
Bei der Herstellung elektrischer Verbindungen mit Leitungskabeln wird üblicherweise zunächst der Kabelmantel teilweise entfernt und dann an den Enden der einzelnen elektrischen Leitungen deren jeweilige Isolierungen. Unter abisolierten Bereichen im Sinne der Erfindung sind jedoch nicht nur solche Bereiche der elektrischen Leitungen zu verstehen, bei denen eine vorher vorhandene Isolierung entfernt wurde, sondern auch solche, die möglicherweise von vorne herein ohne Isolierung, d.h. isolierungsfrei gefertigt wurden.In the production of electrical connections with cable cables, the cable sheath is usually partially removed and then at the ends of the individual electrical lines their respective insulation. Under stripped areas in the context of the invention, however, not only those areas of the electrical lines are to be understood in which a previously existing insulation was removed, but also those that were possibly made from the outset without isolation, ie insulation.
Bevorzugt ist der Abstandhalter nicht unmittelbar mit dem Gehäuse des Steckers verbunden. Insbesondere besteht eine Verbindung zu dem Gehäuse ausschließlich über die Vergussmasse und/oder das Kabel bzw. die elektrischen Leitungen selbst. Dadurch ist die Herstellung des Steckers vereinfacht, und dennoch sind bei ausgehärteter Vergussmasse die elektrischen Leitungen und der Abstandhalter unverrückbar im Gehäuse fixiert.Preferably, the spacer is not directly connected to the housing of the plug. In particular, a connection to the housing exclusively via the potting compound and / or the cable or the electrical lines themselves. This simplifies the production of the plug, and yet the cured electrical potting compound and the spacer are immovably fixed in the housing.
Eine besonders bevorzugte Ausführungsform besteht darin, dass der Abstandhalter durch verbliebene Isolierungs-Teilstücke gebildet wird. Diese sind zwischen den Leitungsenden, die elektrisch mit den Kontaktelementen verbunden sind, und dem abisolierten und später mit Vergussmasse umgebenen Bereich, der der Längswasserdichtigkeit dient, angeordnet. Bei sehr flexiblen, d.h. dünneren oder weicheren elektrischen Leitungen kann es vorteilhaft sein, zwischen den abisolierten Bereichen und dem Kabelmantel, d.h. der Außenisolierung des Kabels zumindest ein Spreizelement anzuordnen, das eine Berührung der Leitungen in den abisolierten Bereichen verhindert. Dies kann nötig sein, da eine gewisse Mindestlänge an Abisolierung zur Sicherung der Längswasserdichtigkeit gewünscht ist. Sind die Leitungen jedoch sehr dünn oder weich und daher zu flexibel, könnte es eventuell trotz des Abstandhalters im abisolierten Bereich selbst bei der Herstellung des Steckers zu Berührungen kommen. Insbesondere bei sogenannten mehradrigen Datenleitungen mit typischerweise kleinem Querschnitt können daher solche Spreizelemente vorteilhaft sein. Das Spreizelement kann beispielsweise durch auf die einzelnen Leitungen aufgezogene Schrumpfschlauchstücke gebildet sein. Bei dickeren oder eigensteifen elektrischen Leitungen, sogenannten Powerleitungen mit meist nur zwei Datenleitungen und größerem Querschnitt (üblicherweise > 0,5 mm2), sind die Isolierungen der einzelnen elektrischen Leitungen meist dick genug, um eine Berührung der einzelnen Leitungen bzw. Litzen auszuschließen, so dass ein weiteres Spreizelement in der Regel nicht notwendig ist.A particularly preferred embodiment is that the spacer is formed by remaining insulation sections. These are arranged between the line ends, which are electrically connected to the contact elements, and the stripped and later encapsulated with encapsulant area, which serves the longitudinal water-tightness. In the case of very flexible, ie thinner or softer electrical lines, it may be advantageous to arrange at least one spreading element between the stripped areas and the cable sheath, ie the outer insulation of the cable, which prevents contact between the lines in the stripped areas. This may be necessary because a certain minimum length of stripping is required to secure the longitudinal water-tightness. However, if the leads are very thin or soft and therefore too flexible, it may possibly come in contact with the connector despite the spacer in the stripped area. In particular, in so-called multi-core data lines with typically small cross-section, therefore, such spreading elements may be advantageous. The expansion element can be formed, for example, by shrink tubing pieces drawn onto the individual lines. For thicker or intrinsically stiff electrical lines, so-called power lines with usually only two data lines and larger cross-section (usually> 0.5 mm 2 ), the insulation of the individual electrical lines are usually thick enough to touch the individual Exclude cables or strands, so that a further expansion element is usually not necessary.

Erfindungsgemäß weisen die einzelnen elektrischen Leitungen 6 zwischen der elektrischen Verbindung mit den Kontaktelementen 4 und der Zusammenführung im Kabel 8 je einen isolierungsfreien bzw. abisolierten Bereich 6' auf, der jeweils von das Innere des Steckergehäuses 1 ausfüllenden Vergussmasse 10 umgeben ist. Damit bei der Montage des Steckers die abisolierten Bereiche 6' der elektrischen Leitungen 6 nicht in Berührung geraten, ist erfindungsgemäß zwischen den abisolierten Bereichen 6' und den elektrisch leitenden Verbindungen mit den Kontaktelementen 4, hier über die Kontaktstifte 5, ein Abstandhalter angeordnet. Dieser wird bei der dargestellten Ausführungsform durch verbliebene Isolierungs-Teilstücke 7' gebildet, die die elektrischen Leitungen 6 in diesem Bereich voneinander beanstanden. Bevorzugt sind diese Isolierungs-Teilstücke 7' bzw. ist der Abstandhalter stabilisierend ebenfalls von Vergussmasse 10 umgeben. Vor den Isolierungs-Teilstücken 7' ist jeweils ein weiterer abisolierter Teilbereich 6" vorhanden sein, der zur weiteren Dichtigkeitsverbesserung ebenfalls von Vergussmasse 10 umgeben ist.According to the invention, the individual electrical lines 6 between the electrical connection with the contact elements 4 and the merger in the cable 8 each have an insulation-free or stripped area 6 ', which is surrounded in each case by the interior of the
Um eine ausreichende Benetzung und Umgebung mit der Vergussmasse 10 zu erreichen, sollten die abisolierten Bereiche 6' hinter dem Abstandhalter 7' zumindest eine Länge L von 3 mm, vorzugsweise sogar mindestens 5 mm Länge aufweisen. Da andererseits eine zu große Länge L wiederum dazu führen könnte, dass die abisolierten Bereiche 6' sich bei der Montage berühren, sollte diese Länge L nicht größer als 20 mm, bevorzugt sogar maximal 10 mm betragen.In order to achieve a sufficient wetting and environment with the potting compound 10, the stripped regions 6 'behind the spacer 7' should have at least a length L of 3 mm, preferably even at least 5 mm in length. On the other hand, since too great a length L could in turn lead to the stripped regions 6 'touching each other during assembly, this length L should not be greater than 20 mm, preferably even not more than 10 mm.
Bei sehr dünnen und/oder flexiblen elektrischen Leitungen 6 könnte es trotzdem zu Berührungen der abisolierten Bereiche 6' kommen, solange diese noch nicht von der Vergussmasse 10 umgeben sind. Um dies zu verhindern, ist es vorteilhaft, zumindest ein zusätzliches Spreizelement einzusetzen. Dieses sollte vorzugsweise im Übergangsbereich zwischen dem abisolierten Bereich 6' und der ummantelnden Isolierung 7 angeordnet sein. Es kann auch die ummantelnde Isolierung 7 vor der Zusammenfassung im Kabel 8 umgeben. Dieses Spreizelement kann bevorzugt durch auf die einzelnen Leitungen 6 aufgezogene Spreizelementstücke 12 gebildet sein, wie es in
Der erfindungsgemäße Stecker verfügt über eine hervorragende Längswasserdichtigkeit und ist dadurch selbst im Unterwassereinsatz sehr sicher. Diese verbesserte Dichtigkeit wird auf die erfindungsgemäße Weise konstruktiv einfach und ohne wesentlich erhöhte Kosten bewirkt.The plug according to the invention has an excellent longitudinal water-tightness and is therefore very safe even in underwater use. This improved tightness is structurally simple and without significantly increased costs in the inventive manner.
