Definitions
- the invention relates to a plastic cup with a ring core choke cast into the plastic cup, the winding ends of which are contacted with the connecting pins cast into the cup wall and with a curved plastic cup base, on the curved outer wall of which standing bodies are formed and whose curvature is at least approximately adapted to the radius of curvature of the ring core choke.
- the US-A-3 845 435 shows approximately a plastic cup of this type, in which, however, several individual containers, each intended for receiving throttles, are combined and equipped with common stands.
- the standing bodies do not protrude beyond the outer wall of the cup base; there is also no surface parallel to the stand for stamping.
- plastic cups are not only characterized by a reduced volume and thus by a reduced absorption capacity for the sealing compound, in addition, the weight of the finished structural units is also considerably reduced.
- the present invention has for its object to provide a plastic cup of the type mentioned, which is not only characterized by the aforementioned high stability and savings in potting compound, but is also designed so that an indelible and easy lettering or stamping of the cup is possible.
- the invention proposes, in the case of a plastic cup of the type mentioned, that the standing bodies are designed as parallel ribs with standing surfaces parallel to the free cup front side, that the standing areas protrude beyond the outer wall of the plastic cup bottom and that the outer wall of the plastic cup bottom in the middle of the cup bottom has a surface parallel to the standing surfaces.
- This area can be used to identify the toroidal choke, the labeling, for. B. type designation, stamped on this surface or molded onto this surface in one step with the production of the plastic cup. Since this area is set back from the stand area, the lettering is secured against dirt or damage to the writing.
- the plastic cup 1 shown in the figures carries electrical connection pins 2 cast into its wall for contacting the winding ends of an annular core choke, not shown in the drawing.
- the bottom of the plastic cup 1 is, as indicated at 3, curved, its radius of curvature preferably being adapted to the radius of curvature of the toroidal core choke.
- the outer wall of the plastic cup base in the center of the cup base is designed as a surface 4 parallel to the standing surfaces.
- This area is the carrier of a stamped or possibly molded lettering, eg. B. Marking the toroidal choke, suitable.

Description
Die Erfindung betrifft einen Kunststoffbecher mit im Kunststoffbecher eingegossener Ringkerndrossel, deren Wickelenden mit den in die Becherwand eingegossenen Anschlußstiften kontaktiert sind und mit gekrümmtem Kunststoffbecherboden, an dessen gekrümmte Außenwandung Standkörper angeformt sind und dessen Krümmung wenigstens angenähert dem Krümmungsradius der Ringkerndrossel angepaßt ist.The invention relates to a plastic cup with a ring core choke cast into the plastic cup, the winding ends of which are contacted with the connecting pins cast into the cup wall and with a curved plastic cup base, on the curved outer wall of which standing bodies are formed and whose curvature is at least approximately adapted to the radius of curvature of the ring core choke.
Die US-A-3 845 435 zeigt angenähert einen Kunststoffbecher dieser Art, bei dem jedoch mehrere, jeweils zur Aufnahme von Drosseln bestimmte Einzelbehälter zusammengefaßt und mit gemeinsamen Standkörpern ausgerüstet sind. Die Standkörper ragen dabei nicht über die Außenwandung des Becherbodens hinaus ; auch ist keine zu den Standflächen parallele Fläche für die Bestempelung vorgesehen.The US-A-3 845 435 shows approximately a plastic cup of this type, in which, however, several individual containers, each intended for receiving throttles, are combined and equipped with common stands. The standing bodies do not protrude beyond the outer wall of the cup base; there is also no surface parallel to the stand for stamping.
Diese Kunststoffbecher zeichnen sich nicht nur durch ein verringertes Volumen und damit durch ein verringertes Aufnahmevermögen für die Vergußmasse aus, zusätzlich wird auch das Gewicht der fertigen Baueinheiten erheblich herabgesetzt.These plastic cups are not only characterized by a reduced volume and thus by a reduced absorption capacity for the sealing compound, in addition, the weight of the finished structural units is also considerably reduced.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Kunststoffbecher der eingangs genannten Art zu schaffen, der sich nicht nur durch die bereits erwähnte hohe Standfestigkeit und Einsparung an Vergußmasse auszeichnet, sondern darüberhinaus so gestaltet ist, daß eine unverwischbare und einfache Beschriftung bzw. Bestempelung des Bechers möglich ist.The present invention has for its object to provide a plastic cup of the type mentioned, which is not only characterized by the aforementioned high stability and savings in potting compound, but is also designed so that an indelible and easy lettering or stamping of the cup is possible.
Zur Lösung dieser Aufgabe schlägt die Erfindung bei einem Kunststoffbecher der eingangs genannten Art vor, daß die Standkörper als parallele Rippen mit zur freien Becher-Stirnseite parallelen Standflächen ausgebildet sind, daß die Standflächen über die Außenwandung des Kunststoffbecherbodens hinausragen und daß die Außenwandung des Kunststoffbecherbodens in Becherbodenmitte eine zu den Standflächen parallele Fläche aufweist.To achieve this object, the invention proposes, in the case of a plastic cup of the type mentioned, that the standing bodies are designed as parallel ribs with standing surfaces parallel to the free cup front side, that the standing areas protrude beyond the outer wall of the plastic cup bottom and that the outer wall of the plastic cup bottom in the middle of the cup bottom has a surface parallel to the standing surfaces.
Diese Fläche kann zur Kennzeichnung der Ringkerndrossel dienen, wobei die Kennzeichnung, z. B. Typenbezeichnung, auf diese Fläche aufgestempelt oder in einem Arbeitsgang mit der Fertigung des Kunststoffbechers an diese Fläche angespritzt ist. Da diese Fläche gegenüber den Standflächen zurückgesetzt ist, ist die Beschriftung gegen Verschmutzung bzw. Beschädigung der Schrift gesichert.This area can be used to identify the toroidal choke, the labeling, for. B. type designation, stamped on this surface or molded onto this surface in one step with the production of the plastic cup. Since this area is set back from the stand area, the lettering is secured against dirt or damage to the writing.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. Es zeigt :
- Figur 1 eine Draufsicht auf einen Kunststoffbecher nach der Erfindung,
Figur 2 einen Schnitt gemäß der Linie 11-11 in Fig.1,Figur 3 eine Seitenansicht des Kunststoffbechers nach Fig. 1 und 2.
- FIG. 1 shows a top view of a plastic cup according to the invention,
- FIG. 2 shows a section along the line 11-11 in FIG. 1,
- 3 shows a side view of the plastic cup according to FIGS. 1 and 2.
Der in den Figuren dargestellte Kunststoffbecher 1, trägt in seine Wandung eingegossene elektrische Anschlußstifte 2 zur Kontaktierung der Wickelenden einer in der Zeichnung nicht dargestellten Ringkerndrossel. Der Boden des Kunststoffbechers 1 ist, wie bei 3 angedeutet, gekrümmt, wobei sein Krümmungsradius vorzugsweise dem Krümmungsradius der Ringkerndrossel angepaßt ist. An die gekrümmte Außenwandung des Bodens sind Standkörper 5, z. B. parallele Rippen, angeformt. Die Rippen weisen Standflächen auf, die zur freien Becher-Stirnseite parallel sind und über die Außenwandung des Kunststoffbecherbodens hinausragen. Wie aus Fig. und 3 ersichtlich ist, ist die Außenwandung des Kunststoffbecherbodens in Becherbodenmitte als eine zu den Standflächen parallele Fläche 4 ausgebildet. Diese Fläche ist als Träger einer aufgestempelten oder ggf. angespritzten Beschriftung, z. B. Kennzeichnung der Ringkerndrossel, geeignet.The plastic cup 1 shown in the figures carries
