Abstract

The contact arrangement contains two contact pieces (20, 24) connected together through a contact link consisting of a number of thin contact laminations (1). The contact laminations (1) are at least partly placed side by side at flat boundary surfaces in the form of a pack and each have at least one recess (4) in which a spring element in the form of a leaf spring is lodged in order to provide contact pressure. This contact arrangement prevents, with a safety margin, any overstraining of the contact-pressure-producing spring elements both during assembly and in operation. This is achieved by the fact that two virtually identically dimensioned leaf springs (9, 10) are used as the spring element; these are arranged in opposite, mirror-image positions and each has an end piece (7, 8) which is lodged in a recess (4) of the contact lamination (1). Such a contact arrangement is particularly suitable as a plug-in connector or load-break connector for power switching devices. <IMAGE>

Description

Bei der Erfindung wird ausgegangen von einer Kontaktan­ordnung nach dem ersten Teil von Patentanspruch 1.The invention is based on a contact arrangement according to the first part of patent claim 1.

Die Erfindung nimmt auf einen Stand der Technik bezug, wie er etwa in der DE-C-18 07 296 beschrieben ist. Bei der bekannten Kontaktanordnung weisen die Kontaktlamellen in der Mitte jeweils eine Ausnehmung auf, in die eine lyraförmig gebogene Blattfeder mit ihrer lyraförmigen Partie mit Vorspannung reibschlüssig eingesetzt ist. Hierdurch wird ein leicht zu handhabendes Bauteil gebildet, bei welchem jedoch wegen der vergleichsweise hoch bean­spruchten lyraförmigen Partie bereits schon bei der Montage der Kontaktanordnung die Streckgrenze des Feder­materials überschritten werden kann.The invention relates to a prior art, such as is described in DE-C-18 07 296. In the known contact arrangement, the contact lamellae each have a recess in the center, into which a lyra-shaped leaf spring with its lyra-shaped part is inserted in a frictionally engaged manner. As a result, an easy-to-use component is formed, in which, however, the elastic limit of the spring material can be exceeded already during the assembly of the contact arrangement because of the comparatively highly stressed lyra-shaped part.

Die Erfindung wie sie in den Patentansprüchen angegeben ist, löst die Aufgabe, eine Kontaktanordnung der gattungs­gemässen Art zu schaffen, bei welcher eine Ueberdehnung der kontaktdruckerzeugenden Blattfedern sowohl bei der Montage als auch beim Betrieb mit Sicherheit vermieden wird.The invention as specified in the claims solves the problem of creating a contact arrangement of the generic type, in which an expansion of the contact pressure-generating leaf springs is avoided with certainty both during assembly and during operation.

Die erfindungsgemässe Kontaktanordnung zeichnet sich dadurch aus, dass durch geeignete Formgebung und Anord­nung der Blattfedern unzulässige Ueberdehnungen entfallen ohne auf besondere fertigungstechnische Toleranzen Rück­sicht nehmen zu müssen. Hierdurch ist sichergestellt, dass trotz einfacher und kostengünstiger Herstellung der Kontaktanordnung die Blattfedern selbst bei starken betrieblichen Beanspruchungen nicht brechen.The contact arrangement according to the invention is characterized in that inadmissible overstretching is eliminated by suitable shaping and arrangement of the leaf springs without having to take into account special manufacturing tolerances. This ensures that, despite simple and inexpensive manufacture of the contact arrangement, the leaf springs do not break even under heavy operational stress.

In Fig. 1 ist eine Kontaktlamelle 1 dargestellt mit einer in deren Mitte vorgesehenen und von seitlichen Flanken 2, 3 begrenzten Ausnehmung 4. Die Flanken 2 bzw. 3 sind jeweils mit einer Hinterschneidung 5 bzw. 6 versehen. In die Ausnehmung 4 ist jeweils ein Endstück 7 bzw. 8 zweier vorzugsweise gleichartig aufgebauter und spiegelbildlich zueinander angeordneter Blattfedern 9 bzw. 10 eingesetzt. Die beiden Endstücke 7 und 8 der beiden Blattfedern 9 und 10 sind gegeneinander geführt und sind von den hinterschnittenen Flanken 2 und 3 in der Ausnehmung 4 gehalten. Jedes der beiden Endstücke 7 bzw. 8 ist jeweils von einem gleichsinnig gekrümmten Teil der zugeordneten Blattfeder 9 bzw. 10 gebildet. An das Endstück 7 bzw. 8 schliesst sich jeweils ein gegensinnig gekrümmtes Auflageteil 11 bzw. 12 mit einem Krümmungsradius an, welcher um ein Vielfaches grösser ist als der Krümmungsradius des Endstückes 7 bzw. 8.1 shows a contact lamella 1 with a recess 4 provided in its center and delimited by lateral flanks 2, 3. The flanks 2 and 3 are each provided with an undercut 5 and 6, respectively. An end piece 7 is in each case in the recess 4 or 8 of two leaf springs 9 and 10, which are preferably constructed identically and arranged in mirror image to one another. The two end pieces 7 and 8 of the two leaf springs 9 and 10 are guided against each other and are held in the recess 4 by the undercut flanks 2 and 3. Each of the two end pieces 7 and 8 is formed in each case by a part of the associated leaf spring 9 or 10 which is curved in the same direction. At the end piece 7 or 8 there is in each case an oppositely curved support part 11 or 12 with a radius of curvature which is many times larger than the radius of curvature of the end piece 7 or 8.

In den Figuren 2 und 3 ist jeweils eine gleichwirkende Kontaktlamelle 1 dargestellt, welche im Gegensatz zur Kontaktlamelle gemäss Fig. 1 zwei jeweils zur Aufnahme eines beider Endstücke 7, 8 vorgesehene Ausnehmungen 13, 14 aufweist mit jeweils lediglich einer hinterschnit­tenen Flanke. Die Ausnehmungen 13, 14 können hierbei -wie in Fig. 2 dargestellt ist - in der Mitte der Kontakt­lamelle 1 oder - wie in Fig. 3 dargestellt ist - an den Enden der Kontaktlamelle 1 angebracht sein.FIGS. 2 and 3 each show an equivalent contact lamella 1, which, in contrast to the contact lamella according to FIG. 1, has two recesses 13, 14 each provided for receiving one of the two end pieces 7, 8, each with only one undercut flank. The recesses 13, 14 can - as shown in FIG. 2 - be made in the middle of the contact plate 1 or - as shown in FIG. 3 - at the ends of the contact plate 1.

Bei der Ausführungsform gemäss Fig. 2 sind die beiden Hinterschneidungen in den einander zugewandten Flanken 15, 16 beider Ausnehmungen 13, 14 vorgesehen. Hierdurch wird wie bei der Ausführungsform gemäss Fig. 1 erreicht, dass die Endstücke 7, 8 der beiden Blattfedern 9, 10 in den beiden Ausnehmungen 13, 14 gehalten sind, und dass zugleich die Krümmungsradien der Blattfedern beim Uebergang von den Endstücken 7, 8 zu den Auflageteilen 11, 12 gegenüber den Krümmungsradien vergleichbarer Teile einer lyraförmig gebogenen Blattfeder gross sind.In the embodiment according to FIG. 2, the two undercuts are provided in the mutually facing flanks 15, 16 of both recesses 13, 14. 1 that the end pieces 7, 8 of the two leaf springs 9, 10 are held in the two recesses 13, 14, and that at the same time the radii of curvature of the leaf springs during the transition from the end pieces 7, 8 the support parts 11, 12 are large compared to the radii of curvature of comparable parts of a lyre-shaped leaf spring.

Bei der Ausführungsform gemäss Fig. 3 sind die beiden Hinterschneidungen in den voneinander abgewandten Flanken 17, 18 beider Ausnehmungen 13, 14 vorgesehen. Hierdurch wird erreicht, dass die Endstücke 7, 8 der beiden Blatt­federn 9, 10 in den beiden Ausnehmungen 13, 14 gehalten sind, und dass zugleich die Krümmungsradien der Blattfe­dern beim Uebergang von den Endstücken 7, 8 zu den Auflage­teilen 11, 12 gegenüber den Krümmungsradien vergleichbar beanspruchter Teile einer lyraförmigen Blattfeder gross sind.In the embodiment according to FIG. 3, the two undercuts are in the flanks facing away from one another 17, 18 of both recesses 13, 14 are provided. This ensures that the end pieces 7, 8 of the two leaf springs 9, 10 are held in the two recesses 13, 14, and that at the same time the radii of curvature of the leaf springs during the transition from the end pieces 7, 8 to the support parts 11, 12 with respect to the radii of curvature comparable stressed parts of a lyre-shaped leaf spring are large.

In Fig. 4 ist dargestellt, wie Kontaktelemente nach Fig. 1 in einer Kontaktanordnung angeordnet sind, welche vorzugsweise in einem Hochstromschaltgerät Verwendung findet. Hierbei bezeichnet 19 ein hohles, vorzugweise hohlzylindrisch ausgebildetes Gehäuse, in welches ein vollzylindrisches Kontaktstück 20 eingeführt ist. Das Kontaktstück 20 ist mit einem Bund 21 versehen und über diesen mittels Schrauben 22 und einem gegebenenfalls teilbaren Ring 23 mit dem Gehäuse 19 verschraubt. In das Gehäuse 19 eingeführt ist in der Eingriffsstellung der Kontaktanordnung ein relativ zum Gehäuse bewegliches Kontaktstück 24. Die Kontaktlamellen 1 werden mittels der sich auf der Innenwand des Gehäuses 19 abstützenden Blattfedern 9, 10 in der dargestellten Eingriffsstellung der Kontaktanordnung gleichermassen an die beiden Kontakt­stücke 20, 24 gepresst. Hierbei wirken die Blattfedern 9, 10 wie einarmige Hebel, welche in der Ausnehmung 4 um ihre als Drehlager wirkenden Endstücke 7, 8 gedreht sind und mit ihren Auflageteilen 11, 12 gegen die Kontakt­lamellen 1 gepresst sind. Wegen der verspannungsfreien Lagerung der Blattfedern 9, 10 in der Ausnehmung 4 und der vergleichsweise grossen Krümmungsradien im Uebergangs­bereich von den Endstücken 7, 8 zu den Auflageteilen 11, 12 wird hierbei eine Ueberdehnung und somit ein Bruch der Blattfedern 9, 10 sowohl bei der Montage als auch beim Betrieb der Kontaktanordnung mit Sicherheit vermieden.FIG. 4 shows how contact elements according to FIG. 1 are arranged in a contact arrangement which is preferably used in a high-current switching device. Here, 19 denotes a hollow, preferably hollow-cylindrical housing, into which a fully cylindrical contact piece 20 is inserted. The contact piece 20 is provided with a collar 21 and screwed to the housing 19 by means of screws 22 and an optionally separable ring 23. Inserted into the housing 19 in the engaged position of the contact arrangement is a contact piece 24 which is movable relative to the housing. The contact blades 1 are equally attached to the two contact pieces 20 by means of the leaf springs 9, 10 which are supported on the inner wall of the housing 19, 24 pressed. Here, the leaf springs 9, 10 act as one-armed levers which are rotated in the recess 4 about their end pieces 7, 8 acting as pivot bearings and are pressed with their support parts 11, 12 against the contact plates 1. Because of the tension-free mounting of the leaf springs 9, 10 in the recess 4 and the comparatively large radii of curvature in the transition area from the end pieces 7, 8 to the support parts 11, 12 there is an expansion and thus a break of the leaf springs 9, 10 both during assembly and avoided with certainty even when operating the contact arrangement.

Wie aus Fig. 5 hervorgeht, besitzt das Gehäuse 19 auf seiner Innenseite am Umfang zwischen Rippen 25 verteilt angeordnete Taschen, in denen jeweils mehrere Kontakt­lamellen 1 zu einem Paket zusammengefasst untergebracht und geführt sind. Zu diesem Zweck weisen die Kontaktla­mellen 1 parallel zueinander verlaufende Begrenzungsflächen und eine geringe Dicke auf und sind ferner die Blatt­federn 9, 10 schmaler als die Kontaktlamellen breit sind. Die Kontaktlamellen 1 der einzelnen Pakete können gegeneinander um 180° verdreht angeordnet sein, wodurch - wie in Fig. 4 dargestellt ist - bei asymmetrisch ausge­bildeten Kontaktlamellen 1 die Kontaktauflagestellen der Kontaktlamellen auf jedem der Kontaktstücke 20, 24 in zwei verschiedenen Ebenen zu liegen kommen.As can be seen from FIG. 5, the housing 19 has, on its inner side, pockets distributed around the circumference between ribs 25, in which in each case a plurality of contact lamellae 1 are housed and guided to form a package. For this purpose, the contact blades 1 have mutually parallel boundary surfaces and a small thickness and the leaf springs 9, 10 are narrower than the contact blades are wide. The contact lamellae 1 of the individual packages can be arranged rotated by 180 ° relative to one another, whereby - as shown in FIG. 4 - in the case of asymmetrically designed contact lamellae 1, the contact bearing points of the contact lamellae come to lie on each of the contact pieces 20, 24 in two different planes.
