Abstract

An electrical connection box or distribution box for the electrical system of a motor vehicle contains flat parts which are used for thermal radiation, are constructed on vertical or elevated sections of busbars and do not project above said busbars. The flat parts extend essentially parallel to an electrically insulating board and require no enlargement of the dimensions of the connection box or distribution box.

Description

Die Erfindung bezieht sich auf eine Stromschienen-Leiter­ platte für einen Anschluß- oder Verteilerkasten zur Verwendung in der elektrischen Anlage etwa eines Kraft­ fahrzeugs.The invention relates to a conductor rail conductor plate for a junction or distribution box Use in the electrical system about a force vehicle.

In einer in Fig. 3 der Zeichnung dargestellten bekannten Anordnung von Stromschienen erfolgt die Abfuhr von Wärme unter Verwendung von verbreiterten, ebenen Abschnitten 1 a und 1 a′ einer zu einer Schaltungsanordnung gehörenden Stromschiene 1 oder eines erhöhten Stegs 1 c, welcher sich zwischen aufrecht stehenden Abschnitten 1 b über andere Stromschienen 1′, 1′′ hinweg erstreckt. Damit die Strom­ schiene in der Lage ist, starke elektrische Ströme ohne übermäßige Erhöhung der Temperatur fortzuleiten, müssen die ebenen Abschnitte 1 a und 1 a′ sowie der erhöhte Steg 1 c beträchtlich verbreitert werden. Die Abmessungen des elektrischen Anschluß- oder Verteilerkastens, in welchem eine die Stromschienen tragende Platine 2 aus einem isolierenden Werkstoff untergebracht ist, sind jedoch durch den für den Einbau des Anschlußkastens verfügbaren Raum in einem Kraftfahrzeug begrenzt. Deshalb stehen einer Verbreiterung der ebenen Abschnitte sowie des erhöhten Stegs erhebliche Schwierigkeiten entgegen.In a in Fig. 3 of the drawing illustrated known arrangement of busbars takes place the removal of heat using widened planar portions 1 a and c 1 a 'a belonging to a circuit conductor rail 1, or a raised ridge 1, which extends property between erect Sections 1 b extends across other busbars 1 ', 1 ''. So that the power rail is able to transmit strong electric currents without excessive temperature increases, the flat sections 1 a and 1 a 'and the raised web 1 c must be widened considerably. The dimensions of the electrical connection or distribution box, in which a circuit board 2 carrying the busbars is made of an insulating material, are limited by the space available for the installation of the connection box in a motor vehicle. For this reason, widening of the flat sections and of the raised web are faced with considerable difficulties.

Ein Ziel der Erfindung ist die Schaffung einer Stromschie­ nenleiterplatte, welche eine erhöhte Wärmeabfuhr oder Wärmeabstrahlung ermöglicht, ohne daß dabei ein nennens­ wert größerer Platzbedarf für den Einbau der Stromschienen­ anordnung notwendig ist.An object of the invention is to create a current rail printed circuit board, which increases heat dissipation or Heat radiation allows, without a name worth larger space requirements for the installation of the busbars arrangement is necessary.

Bei einer Stromschienen-Leiterplatte der vorstehend genannten Art ist dieses Ziel gemäß der Erfindung dadurch erreicht, daß an wenigstens einem aufrecht stehenden Abschnitt wenigstens einer Stromschiene der Leiterplatte ein der Wärmeabstrahlung dienendes flächiges Teil parallel zu einer aus elektrisch isolierenden Werkstoff geformten Platine hervorsteht, auf welcher die Stromschienen flach liegend befestigt sind.In a busbar circuit board of the above mentioned type, this is the aim according to the invention achieved that at least one standing upright Section of at least one busbar of the circuit board a flat part serving for heat radiation in parallel to a molded from electrically insulating material  The board protrudes on which the busbars are flat are attached horizontally.

Im folgenden sind Ausführungsbeispiele der Erfindung anhand der Zeichnung erläutert. Es zeigen:The following are exemplary embodiments of the invention explained using the drawing. Show it:

Fig. 1 und 2 Schrägansichten von Teilen jeweils einer Stromschienen-Leiterplatte in bevorzugten Ausfüh­ rungsformen der Erfindung und Fig. 1 and 2 are oblique views of parts in each case of a busbar printed circuit board in preferred embodiments of the invention and exporting approximately

Fig. 3 eine Schrägansicht von Teilen einer Stromschienen- Leiterplatte in einer bekannten Ausführungsform. Fig. 3 is an oblique view of parts of a busbar circuit board in a known embodiment.

In Fig. 1 steht ein der Wärmeabstrahlung dienendes flächiges Teil 1 d am unteren Rand eines erhöhten Stegs 1 c hervor. Das flächige Teil 1 d erstreckt sich parallel zu einer Platine 2 aus elektrisch isolierendem Werkstoff, und der Steg 1 c verbindet zwei aufrecht stehende Abschnitte 1 b miteinander. In einer anderen, in Fig. 2 gezeigten Ausführungsform ist ein der Wärmeabstrahlung dienendes flächiges Teil 1 d′ von dem erhöhten Steg 1 c abgewinkelt, so daß es an dessen oberem Rand parallel zur isolierenden Platine 2 hervorsteht. Die wärmeabstrahlenden flächigen Teile 1 d oder 1 d′ können beliebig große Abmessungen haben, solange sie nicht über die äußeren Ränder der isolierenden Platine 2 hervorstehen. Ferner können die wärmeabstrahlend flächigen Teile 1 d oder 1 d′ relativ zur isolierenden Platine 2 aufwärts oder abwärts geneigt verlaufen, solange sie dabei nicht übermäßig über die aufrecht stehenden Abschnitte 1 b oder den erhöhten Steg 1 c hervorstehen. Im Falle einer einen langen und geraden Leiterabschnitt 1 e aufweisenden Stromschiene 1′′ kann entlang dem geraden Leiterabschnitt 1 e ein aufrecht stehender Schenkel 1 b′ abgewinkelt sein, welcher ein weiteres der Wärmeabstrahlung dienendes flächiges Teil 1 d′′ trägt. Die einzelnen Strom­ schienen 1, 1′, 1′′ haben aufrecht stehende Anschlußzungen für den Anschluß von externen Leitern und dergl.In Fig. 1 protrudes the heat radiation flat part 1 d at the lower edge of a raised web 1 c . The flat part 1 d extends parallel to a board 2 made of electrically insulating material, and the web 1 c connects two upright sections 1 b to one another. In another embodiment shown in Fig. 2 is a heat radiation flat part 1 d 'angled from the raised web 1 c , so that it protrudes parallel to the insulating board 2 at its upper edge. The heat-radiating flat parts 1 d or 1 d 'can have any size, as long as they do not protrude beyond the outer edges of the insulating board 2 . Wärmeabstrahlend the flat parts 1 also may or d 'upwards or downwards inclined run 1 d relative to the insulative circuit board 2, as long as they thereby do not protrude excessively over the upstanding portions 1 b or 1 c the raised ridge. In the case of a long and straight conductor section 1 e having busbar 1 '', an upright leg 1 b 'can be angled along the straight conductor section 1 e , which bears another flat part 1 d ''serving for heat radiation. The individual current rails 1 , 1 ', 1 ''have upright tabs for connecting external conductors and the like.

Durch das Vorhandensein der wärmeabstrahlenden flächigen Teile 1 d, 1 d′ und/oder 1 d′′ ist die Wärmeabfuhr von der erfindungsgemäßen Stromschienen-Leiterplatte erheblich verbessert. Due to the presence of the heat-radiating flat parts 1 d , 1 d 'and / or 1 d '', the heat dissipation from the busbar circuit board according to the invention is significantly improved.

Da sich das der Wärmeabstrahlung dienende flächige Teil 1 d oder 1 d′ parallel zur Isolierstoffplatine 2 erstreckt, steht es nicht aufwärts über den erhöhten Steg 1 c hervor. Daher können die Abmessungen der Isolierstoffplatine 2 sowie die Höhe des elektrischen Anschlußkastens dieselben sein wie in der bekannten Ausführungsform, wobei auch die grundsätzliche Anordnung der Stromschienen 1, 1, usw. nicht geändert zu werden braucht. Im Falle eines erhöhten Stegs 1 c von größerer Länge wird dieser durch das von ihm abgewinkelte wärmeabstrahlende flächige Teil 1 d oder 1 d′ noch zusätzlich versteift.Since the heat radiating flat part 1 d or 1 d 'extends parallel to the Isolierstoffplatine 2 , it does not protrude upwards over the raised web 1 c . Therefore, the dimensions of the Isolierstoffplatine 2 and the height of the electrical connection box can be the same as in the known embodiment, the basic arrangement of the busbars 1 , 1 , etc. need not be changed. In the case of a raised web 1 c of greater length, this is additionally stiffened by the heat-radiating flat part 1 d or 1 d 'angled by it.

Wie man aus vorstehender Beschreibung erkennt, ermöglicht die Erfindung eine beträchtlich verbesserte Wärmeabfuhr von einer Stromschienen-Leiterplatte ohne nennenswerte Veränderung der Anordnung der Stromschienen mit ihren Anschlüssen, der Abmessungen der Isolierstoffplatine 2 und der Höhe des elektrischen Anschlußkastens.As can be seen from the above description, the invention enables a considerably improved heat dissipation from a busbar circuit board without any significant change in the arrangement of the busbars with their connections, the dimensions of the insulating board 2 and the height of the electrical connection box.
