Abstract

The component, e.g. a resistor, capacitor, or gas-filled overvoltage diverter, has a pair of lead wires (24,25) projecting from its opposing ends, each bent to lie in the plane of the component end face. The free ends (26,27) of the lead wires are bent at an angle in the parallel plane, to provide horizontal support feet. A further support point lying in a triangular configuration with the support feet is provided by the bent free end (29) of a third lead wire (28) extending from the component mantle at its centre.

Description

Die Erfindung liegt auf dem Gebiet des Zusammenbauens von ge­ druckten Schaltungen mit elektrischen Bauelementen und ist bei der hierfür erforderlichen Ausgestaltung solcher Bauele­ mente anzuwenden, die eine zylindrische Form haben und mit wenigstens zwei Anschlußdrähten versehen sind; entsprechende Bauelemente können beispielsweise Widerstände, Kondensatoren und gasgefüllte Überspannungsableiter sein.The invention is in the field of assembling ge printed circuits with electrical components and is in the design of such components required for this to use elements that have a cylindrical shape and with at least two connecting wires are provided; appropriate Components can for example be resistors, capacitors and be gas-filled surge arresters.

Bei der Bestückung von Schaltplatinen geht man in neuerer Zeit dazu über, die Anschlußdrähte der mit den Leiterbahnen einer Schaltplatine zu verlötenden elektrischen Bauelemente nicht mehr in Bohrungen der Leiterbahnen zu stecken, sondern die mit entsprechenden Anschlüssen versehenen Bauelemente auf die ungelochten Leiterbahnen aufzusetzen. Um auch zylinder­ förmige Bauelemente mit zwei axial abstehenden Anschlußdräh­ ten mit möglichst einfachen Mitteln auf einer Schaltplatine standsicher anordnen zu können, ist es bereits bekannt, die Anschlußdrähte um 180° zum Bauelement hin derart in eine ge­ meinsame Ebene abzubiegen, daß der Gewichtsvektor des Bauele­ mentes beim Einsatz des Bauelementes in eine Schichtschaltung das Zentrum der durch die Enden der Anschlußdrähte begrenzten Ebene durchdringt (DE 25 08 702 A). Bei relativ langen zylin­ drischen Bauelementen weisen auch die jeweils einen Fuß bil­ denden Abschnitte der Anschlußdrähte eine relativ große Länge auf.When assembling circuit boards one goes in newer ones Time to do this, connect the leads to the traces a circuit board to be soldered electrical components no longer stuck in holes in the conductor tracks, but the components provided with appropriate connections to put on the unperforated conductor tracks. To cylinder too shaped components with two axially projecting connecting wires with the simplest possible means on a circuit board It is already known to be able to arrange in a stable manner Connection wires through 180 ° to the component in such a way in a ge turn common plane that the weight vector of the Bauele mentes when using the component in a layer circuit the center of those bounded by the ends of the leads Plane penetrates (DE 25 08 702 A). With a relatively long cylin drical components also have a foot bil end portions of the leads a relatively large length on.

Speziell bei gasgefüllten Überspannungsableitern gibt es Aus­ führungsformen, bei denen neben den beiden stirnseitig ange­ ordneten Elektroden eine weitere, mittig angeordnete Elektro­ de vorgesehen ist und die demzufolge zwei stirnseitig ange­ ordnete Anschlußdrähte und einen mantelseitig angeordneten Anschlußdraht aufweisen.There is a problem with gas-filled surge arresters in particular leadership forms in which in addition to the two on the front arranged another electrode in the middle de is provided and consequently two on the front  arranged connection wires and one arranged on the jacket side Have connection wire.

Ausgehend von einem Bauelement mit den Merkmalen des Oberbe­ griffes des Patentanspruches liegt der Erfindung die Aufgabe zugrunde, auf einfache Weise eine standsichere Anordnung ei­ nes solchen Bauelementes zu ermöglichen.Starting from a component with the characteristics of the Oberbe handle of the claim, the invention is the task based, in a simple manner a stable arrangement egg to enable such a component.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß die Anschlußdrähte parallel zu den Stirnflächen des Bau­ elementes derart abgebogen sind, daß ihre freien Enden Füße bilden, deren räumliche Anordnung zum Zwecke einer stabilen horizontalen Aufstellung des Bauelementes so gewählt ist, daß sie die Eckpunkte eines Dreieckes bilden, wobei die freien Enden abgeflacht sind und eine Auflagefläche von etwa 1 bis 10 mm² aufweisen.To achieve this object, the invention provides that the connecting wires are parallel to the end faces of the construction element are bent so that their free ends feet form, their spatial arrangement for the purpose of a stable horizontal placement of the component is chosen so that they form the corner points of a triangle, the free ones Ends are flattened and a contact surface of about 1 to Have 10 mm².

Eine derartige Formgebung der Anschlußdrähte ermöglicht eine standsichere, horizontale Anordnung des zylinderförmigen Bau­ teiles, wobei die Abflachung der freien Enden der üblicher­ weise einen kreisförmigen Querschnitt aufweisenden Anschluß­ drähte, die beispielsweise durch eine Quetschbeanspruchung erreicht wird, der Vergrößerung der Kontaktfläche und der Verbesserung der mechanischen Festigkeit der angestrebten Lötverbindung zwischen den Anschlußdrähten und der Schaltpla­ tine dient.Such a shaping of the connecting wires enables one stable, horizontal arrangement of the cylindrical structure part, the flattening of the free ends of the usual have a circular cross-section connection wires, for example, due to crushing stress is achieved, the enlargement of the contact area and the Improve the mechanical strength of the target Solder connection between the connecting wires and the circuit board tine serves.

Fig. 3 ausschnittsweise einen im Fußbereich abge­ flachten Anschlußdraht mit an sich kreisför­ migem Querschnitt. Fig. 3 excerpt a abge flattened connecting wire with a circular cross-section in the foot area.

Die Fig. 1 und 2 zeigen einen Drei-Elektroden-Ableiter, der aus einer Mittelelektrode 23, zwei Keramikisolatoren 33 und 34 und den beiden Endelektroden 21 und 22 sowie den An­ schlußdrähten 24, 25 und 28 besteht. Die beiden Anschlußdräh­ te 24 und 25 sind axial an die Endelektroden 21 und 22 ange­ schweißt, während der Anschlußdraht 28 am äußeren Umfang der Mittelelektrode 23 tangential angeschweißt ist. Die Anschluß­ drähte 24 und 25 sind so abgebogen, daß die freien Enden je­ weils in einer parallel zu den Stirnflächen des zylinderför­ migen Überspannungsableiters verlaufen. Sie bilden auf diese Weise zwei Beine, die an ihren freien Enden mit einem Fuß 26 bzw. 27 versehen sind. Ein drittes Bein wird von dem An­ schlußdraht 28 gebildet, der radial nach außen abgebogen ist und ebenfalls an seinem freien Ende mit einem Fuß 29 versehen ist. Die Abbiegung der Anschlußdrähte und die Anordnung der Füße ist dabei so gewählt, daß die drei Füße 26, 27 und 29 gemäß Fig. 2 die Eckpunkte eines Dreieckes D, im vorliegen­ den Fall eines gleichschenkligen Dreiecks bilden; bei Anord­ nung des so ausgebildeten Ableiters auf einer Platine 30 liegt der Schwerpunkt des Ableiters innerhalb des Dreieckes D, wodurch eine hohe Standsicherheit gewährleistet ist. Figs. 1 and 2 show a three-electrode surge arrester, consisting of a center electrode 23, two ceramic insulators 33 and 34 and the two end electrodes 21 and 22 and the on-circuiting wires 24, 25 and 28 is made. The two connecting wires 24 and 25 are axially welded to the end electrodes 21 and 22 , while the connecting wire 28 is welded tangentially to the outer circumference of the central electrode 23 . The connecting wires 24 and 25 are bent so that the free ends each run in a parallel to the end faces of the zylinderför shaped surge arrester. In this way, they form two legs which are provided with a foot 26 and 27 at their free ends. A third leg is formed by the closing wire 28 , which is bent radially outwards and is also provided at its free end with a foot 29 . The bend of the connecting wires and the arrangement of the feet is chosen so that the three feet 26 , 27 and 29 according to FIG. 2 form the corner points of a triangle D, in the present case an isosceles triangle; When arranging the arrester thus formed on a circuit board 30 , the center of gravity of the arrester lies within the triangle D, which ensures a high level of stability.

Gemäß Fig. 3 ist jeder Anschlußdraht an seinem freien Ende 31 mit einer Abflachung 32 versehen, um eine genügend große Lötfläche bei der Auflage auf einer Leiterbahn der Platine 30 bzw. der Platine 10 zu gewährleisten. Diese Abflachung 32 und die Länge der Füße 26, 27 und 29 sind dabei so zu wählen, daß die Auflagefläche wenigstens 1 mm² beträgt, zweckmäßig bei etwa 4 mm² liegt.According to FIG. 3, each connecting wire is provided at its free end 31 with a flattened area 32 in order to ensure a sufficiently large soldering area when resting on a conductor track of the circuit board 30 or the circuit board 10 .
