Description

Beschreibungdescription
Elektrisches BauelementElectrical component
Die vorliegende Erfindung betrifft ein elektrisches Bauelement nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to an electrical component according to the preamble of patent claim 1.
Elektrische Bauelemente in Form von Kaltleitern werden unter anderem zur Entmagnetisierung von Lochmasken von Farbbildröh- ren in dazu vorgesehenen Schaltungen verwendet, welche aus einer Entmagnetisierungsspule und einem dazu in Reihe liegenden Kaltleiter als Schalter zum Abregein des Spulenstromes bestehen .Electrical components in the form of PTC thermistors are used, among other things, for demagnetizing shadow masks of color picture tubes in the circuits provided, which consist of a demagnetizing coil and a PTC thermistor in series as a switch for de-energizing the coil current.
Derartige Kaltleiter werden im Prinzip durch einen die Bauelementefunktion definierenden Bauelementekörper in Form einer Scheibe mit angelöteten Anschlußdrähten und einer Kunst- stoffhüllung oder durch eine in ein Kunststoffgehäuse geklemmte Kaltleiterscheibe gebildet.In principle, PTC thermistors of this type are formed by a component body defining the component function in the form of a disk with soldered connecting wires and a plastic sheath, or by a PTC thermistor disk clamped in a plastic housing.
Bekannte Gehäusebauformen werden dabei aus einem Gehäuseoberteil und einem Gehäuseunterteil mit zwei Federkontaktelementen gebildet. Die Federkontaktelemente werden zur externen Beschaltung durch das Gehäuseunterteil geführt, wozu in dem dieses Gehäuseunterteil bildenden Kunststoff mehr oder weniger große Öffnungen vorgesehen sind.Known housing designs are formed from an upper housing part and a lower housing part with two spring contact elements. The spring contact elements are guided for external wiring through the lower housing part, for which purpose more or less large openings are provided in the plastic forming this lower housing part.
Es sind bisher Bauformen bekannt geworden, bei denen die Kontaktfederelemente mit jeweils einem Ende kontaktierend am Bauelementekörper angreifen, von dort abgewinkelt zur Gehäuseinnenseite und längs dieser Gehäuseinnenseite nach außen geführt sind. Dabei sind die am Bauelementekörper angreifenden Teile der Kontaktfederelemente jedoch nur einseitig gestützt, so daß bei vorgegebenen Maßen der Kontaktfederelemen- te der Druck für eine sichere Klemmkontaktierung nicht ausreichen kann. Werden andererseits die Maße der Kontaktfedere- lemente zur Erhöhung des Drucks für eine sichere Klemmkontak- tierung vergrößert, so ergeben sich daraus konstruktive Beschränkungen für die Bauelemente.Designs have hitherto become known in which the contact spring elements engage in contacting manner on the component body with one end each, are angled from there to the inside of the housing and are guided outwards along this inside of the housing. The parts of the contact spring elements engaging on the component body are, however, only supported on one side, so that, given the dimensions of the contact spring elements, the pressure cannot be sufficient for a secure clamping contact. On the other hand, are the dimensions of the contact spring elements to increase the pressure for a secure clamping contact? tion increases, this results in constructive restrictions for the components.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine hinsichtlich Zuverlässigkeit und Betriebssicherheit optimierte Konstruktion für eine Klemmkontaktierung des Bauelementekörpers im Bauelementegehäuses zu schaffen.The present invention has for its object to provide a design that is optimized with regard to reliability and operational safety for a clamping contact of the component body in the component housing.
Diese Aufgabe wird bei einem elektrischen Bauelement der ein- gangs genannten Art erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.This object is achieved according to the invention in the case of an electrical component of the type mentioned at the outset by the features of the characterizing part of patent claim 1.
Weiterbildungen der Erfindung sind Gegenstand von Unteran- sprüchen .Further developments of the invention are the subject of subclaims.
Die Erfindung wird nachfolgend anhand eines Ausführungsbei- spiels gemäß der einzigen Figur der Zeichnung näher erläutert . Diese Figur zeigt eine teilweise geschnittene Seitenansicht eines erfindungsgemäßen elektrischen Bauelementes in Form eines Kaltleiters.The invention is explained in more detail below on the basis of an exemplary embodiment according to the single figure of the drawing. This figure shows a partially sectioned side view of an electrical component according to the invention in the form of a PTC thermistor.
Gemäß der Figur der Zeichnung wird ein erfindungsgemäßer Kaltleiter generell durch einen Bauelementekörper in Form einer Kaltleiterscheibe 1, ein Gehäuse 2 sowie Kontaktfederele- mente 3 und 4 gebildet. Für die nachfolgenden Erläuterungen sind eine Gehäuseoberseite gesondert mit 2-1 und ein Gehäuseboden mit 2-2 bezeichnet. Der die Bauelementefunktion definierende Bauelementekörper in Form einer Kaltleiterscheibe 1 wird an der Gehäuseoberseite 2-1 durch Ansätze 2-3 und am Ge- häuseboden 2-2 durch eine Ausnehmung 2-4 in seiner Lage gehalten .According to the figure of the drawing, a PTC thermistor according to the invention is generally formed by a component body in the form of a PTC thermistor disk 1, a housing 2 and contact spring elements 3 and 4. For the following explanations, an upper side of the housing is designated 2-1 and a housing base 2-2. The component body defining the component function in the form of a PTC thermistor disk 1 is held in position on the upper side of the housing 2-1 by lugs 2-3 and on the housing base 2-2 by a recess 2-4.
Erfindungsgemäß sind die Federkontaktelemente 3, 4 jeweils an zwei Abstützstellen 3-1, 3-2 bzw. 4-1, 4-2 im Gehäuse 1 abge- stützt, wobei die Absatzstellen auf voneinander abgewandten Seiten jeweils einer Kontaktstelle 3-5 bzw. 4-5 am Bauelementekörper 1 angreifen. Die Federkontaktelemente 3, 4 sind vorzugsweise Federblechelemente, die gesehen in einer Richtung von den Abstützstellen 3-1, 3-2 bzw. 4-1, 4-2 am Gehäuse 2 zur Kontaktstelle 3-5 bzw. 4-5 am Bauelementekörper 1 hin vorzugsweise konvex ausgebildet sind. Die Abstützstellen 3-1, 3-2 bzw. 4-1, 4-2 liegen wie dargestellt im Bereich der Gehäuseoberseite 2-1 bzw. des Gehäusebodens 2-2.According to the invention, the spring contact elements 3, 4 are each supported at two support points 3-1, 3-2 or 4-1, 4-2 in the housing 1, the heel points on sides facing away from one another each having a contact point 3-5 or 4 -5 engage component body 1. The spring contact elements 3, 4 are preferably spring plate elements, seen in one direction from the support points 3-1, 3-2 or 4-1, 4-2 on the housing 2 to the contact point 3-5 or 4-5 on the component body 1 are preferably convex. The support points 3-1, 3-2 or 4-1, 4-2 are, as shown, in the area of the top of the housing 2-1 or the housing base 2-2.
Die Abstützstellen 3-1, 3-2 bzw. 4-1, 4-2 der Federkontaktelemente 3, 4 sind im Bereich des Gehäusebodens 2-2 vorzugsweise dadurch gebildet, daß eine Verlängerung des konvexen Federkontaktelemente-Teils durch den Gehäuseboden 2-2 gestochen ist. Die Durchstichbereiche sind dabei mit 3-3 bzw. 4-3 bezeichnet.The support points 3-1, 3-2 or 4-1, 4-2 of the spring contact elements 3, 4 are preferably formed in the area of the housing base 2-2 by piercing an extension of the convex spring contact element part through the housing base 2-2 is. The piercing areas are designated 3-3 and 4-3.
Durch die erfindungsgemäße Ausbildung der Federkontaktelemente 3, 4 wird einerseits eine hohe dauerhafte Klemmwirkung realisiert, die für das Lebensdauerverhalten des Bauelementes von entscheidender Bedeutung ist. Da darüber hinaus die Federkontaktelemente 3, 4 mittels ihrer Verlängerungen 3-4 bzw. 4-4 durch den Gehäuseboden 2-2 gestochen sind, bleibt die sich daraus ergebende Gehäuseöffnung auf den Federquerschnitt beschränkt. Daraus ergibt sich eine Minimierung der Geh use- Öffnung mit dem wesentlichen Vorteil, daß externe Schadstoffe weitgehend vom Gehäuseinneren ferngehalten werden können, was wiederum zu einer Erhöhung der Betriebssicherheit führt . The inventive design of the spring contact elements 3, 4 on the one hand realizes a high permanent clamping effect, which is of crucial importance for the life behavior of the component. In addition, since the spring contact elements 3, 4 are pierced through the housing base 2-2 by means of their extensions 3-4 or 4-4, the resulting housing opening remains limited to the spring cross section. This results in a minimization of the housing opening with the essential advantage that external pollutants can be largely kept away from the interior of the housing, which in turn leads to an increase in operational reliability.
