Der Erfindung liegt das technische Problem zugrunde, einen Ladestecker zu schaffen, der beim Einsatz im Freien verbesserte Eigenschaften aufweist.The invention is based on the technical problem of creating a charging plug which has improved properties when used outdoors.
Die Lösung des technischen Problems ergibt sich durch einen Ladestecker mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to the technical problem results from a charging plug with the features of
Dabei ist das äußere Gehäuse mindestens zweiteilig ausgebildet, wobei mindestens ein erstes Gehäuseteil die Oberseite des Ladesteckers und ein zweites Gehäuseteil die Unterseite des Ladesteckers bildet, wobei das die Unterseite bildende Gehäuseteil eine höhere Wärmeleitfähigkeit aufweist als das die Oberseite bildende Gehäuseteil. Der Grundgedanke dabei ist, verstärkt Wärme in die Unterseite des Gehäuses einzuleiten, sodass der auf der Oberseite liegende Schnee nicht schmilzt.The outer housing is designed in at least two parts, with at least one first housing part forming the top of the charging plug and a second housing part forming the bottom of the charging plug, the housing part forming the bottom having a higher thermal conductivity than the housing part forming the top. The basic idea here is to introduce more heat into the underside of the housing so that the snow on the top does not melt.
Hierzu weist das Gehäuse eine Isolationsschicht auf, die auf die Innenseite des ersten Gehäuseteils aufgebracht ist, wobei die Isolationsschicht eine geringere Wärmeleitfähigkeit aufweist als das Material des ersten Gehäuseteils. Dem liegt die Erkenntnis zugrunde, dass es beim Laden im Freien dazu kommen kann, dass Schnee auf die Oberseite fällt. Beim elektrischen Laden kommt es zu einer Wärmeentwicklung, die den Schnee zum Schmelzen bringt, sodass Wasser in die Verbindung Ladestecker-Ladebuchse fließen kann. Wird dann der Ladevorgang beendet, kann es zu Eisbildung kommen und der Ladestecker nicht mehr gezogen werden. Dies wird nun durch die thermische Isolationsschicht verhindert bzw. zumindest reduziert. Der Grundgedanke dabei ist, den Wärmeeintrag in die Oberseite im Vergleich zum restlichen Gehäuse zu reduzieren. Dabei hat die Isolationsschicht an der Innenseite des ersten Gehäuseteils den größten Effekt, da so der Wärmeeintrag aus dem Inneren des Ladesteckers in die Oberseite des Gehäuses verhindert wird. Zusätzlich kann durch weitere Maßnahmen die thermische Leitfähigkeit des zweiten Gehäuseteils im Vergleich zum ersten Gehäuseteil erhöht werden. Beispielsweise können für beide Gehäuseteile unterschiedliche Materialien verwendet werden. Alternativ können beispielsweise wärmeleitfähige Partikel in eine Spritzgussmasse des zweiten Gehäuseteils beigemischt werden oder es können wärmeleitfähige Schichten in das zweite Gehäuseteil auf- oder eingebracht werden.For this purpose, the housing has an insulation layer which is applied to the inside of the first housing part, the insulation layer having a lower thermal conductivity than the material of the first housing part. This is based on the knowledge that when charging outdoors, snow can fall on the top. When charging electrically, heat is generated that melts the snow, so that water can flow into the charging plug-charging socket connection. If the charging process is then ended, ice can form and the charging plug can no longer be pulled. This is now prevented or at least reduced by the thermal insulation layer. The basic idea is to reduce the heat input into the top compared to the rest of the housing. The insulation layer on the inside of the first housing part has the greatest effect, since it prevents the introduction of heat from the interior of the charging plug into the top of the housing. In addition, the thermal Conductivity of the second housing part can be increased compared to the first housing part. For example, different materials can be used for both housing parts. Alternatively, for example, thermally conductive particles can be mixed into an injection molding compound of the second housing part, or thermally conductive layers can be applied or introduced into the second housing part.
In einer weiteren Ausführungsform besteht das zweite Gehäuseteil mindestens teilweise aus Metall, vorzugsweise aus Aluminium. Der Vorteil von Aluminium ist dessen gute Wärmeleitfähigkeit bei geringem Gewicht und guter Verarbeitbarkeit.In a further embodiment, the second housing part consists at least partially of metal, preferably of aluminum. The advantage of aluminum is its good thermal conductivity with low weight and good processability.
In einer weiteren Ausführungsform weist das zweite Gehäuseteil oberflächenvergrößernde Strukturen wie beispielsweise Rippen auf, um die Wärme besser abzuführen.In a further embodiment, the second housing part has surface-enlarging structures such as ribs, for example, in order to better dissipate the heat.
In einer weiteren Ausführungsform weist das zweite Gehäuseteil eine Beschichtung auf, die eine geringere thermische Leitfähigkeit im Vergleich zum Basismaterial des zweiten Gehäuseteils aufweist. Die Beschichtung ist dabei außen angeordnet und soll verhindern, dass der Griffbereich des Ladesteckers zu warm wird, um diesen anzufassen. Dabei muss die Beschichtung nicht vollständig das zweite Gehäuseteil abdecken, sondern nur dort, wo angefasst wird.In a further embodiment, the second housing part has a coating which has a lower thermal conductivity compared to the base material of the second housing part. The coating is arranged on the outside and is intended to prevent the grip area of the charging plug from becoming too warm to touch. The coating does not have to completely cover the second housing part, but only where it is touched.
In einer weiteren Ausführungsform weist die Isolationsschicht mindestens eine ins Gehäuseinnere weisende reflektierende Oberfläche auf, um Wärmestrahlung zu reflektieren.In a further embodiment, the insulation layer has at least one reflective surface pointing into the interior of the housing in order to reflect thermal radiation.
