von profilierten und gelochten Baugruppenträgernof profiled and perforated subracks
für Elektroinstallationsverteilerfor electrical installation distributors
Die Neuerung betrifft ein Verbindungselement gemäß dem Oberbegriff der Schutzansprüche 1 und 3.The innovation concerns a connecting element according to the generic term of claims 1 and 3.
Profilierte und gelochte Baugruppenträger werden unter Zuhilfenahme von Verbindungselementen der unterschiedlichsten Art durch Verschrauben und gegebenenfalls auch durch zusätzliches Zusammenstecken miteinander verbunden (vgl. DE-GM 88 02 893.3). Nachteilig bei diesen bekannten Verbindungstechniken ist, daß bis zu vier Schrauben je Baugruppenträger benötigt werden, was je nach Anzahl der zu verbindenden Baugruppenträger trotz Verwendung motorischer Schrauber äußerst zeitaufwendig sein kann.Profiled and perforated subracks are connected to one another using a wide variety of connecting elements by screwing and, if necessary, by additionally plugging them together (see DE-GM 88 02 893.3). The disadvantage of these known connection techniques is that up to four screws are required per subrack, which, depending on the number of subracks to be connected, can be extremely time-consuming despite the use of motorized screwdrivers.
Der Neuerung liegt daher die Aufgabe zugrunde, ein Verbindungselement zu schaffen, das durch schraubenloses Verbinden und Lösen von profilierten und gelochten Baugruppenträgern den Montageaufwand deutlich verringert.The innovation is therefore based on the task of creating a connecting element that significantly reduces the assembly effort by connecting and releasing profiled and perforated assembly carriers without screws.
Die Lösung dieser Aufgabe gelingt durch die kennzeichnenden Merkmale der Schutzansprüche 1 und 3. Weitere vorteilhafte Ausgestaltungen des Verbindungselements gemäß der vorliegenden Neuerung sind in den Unteransprüchen angegeben.This problem is solved by the characterizing features of claims 1 and 3. Further advantageous embodiments of the connecting element according to the present innovation are specified in the subclaims.
Anhand eines in den Zeichnungsfiguren dargestellten Ausführungsbeispiels sei im folgenden das Verbindungselement für Baugruppenträger näher erläutert. Es zeigt:The connecting element for module carriers is explained in more detail below using an example shown in the drawings. It shows:
Fig. 1 eine perspektivische Ansicht eines profilierten Verbindungselementes mit eingesetzten Federelementen;Fig. 1 is a perspective view of a profiled connecting element with inserted spring elements;
Fig. 2 eine perspektivische Seitenansicht von zwei Baugruppenträgern, die mittels eines Verbindungselementes kraftschlüssig verbunden sind;Fig. 2 is a perspective side view of two assembly carriers that are connected by means of a connecting element in a force-locking manner;
Fig. 3 eine schematische Schnittdarstellung, bei der als Verbindungselement ebenfalls eine Feder in Form eines U-förmigen Winkelstücks dient, bei der jedoch der Federschenkel nach innen vorgespannt ist und dort unter Zuhilfenahme eines Exzenters in eine kraftschlüssige Position einstellbar ist;Fig. 3 is a schematic sectional view in which a spring in the form of a U-shaped angle piece also serves as the connecting element, but in which the spring leg is pre-tensioned inwards and can be adjusted there into a force-locking position with the aid of an eccentric;
Fig. 4 eine schematische Schnittdarstellung gemäß Fig. 3 mit über dem Exzenter kraftschlüssig eingestelltem Federschenkel.Fig. 4 is a schematic sectional view according to Fig. 3 with the spring leg adjusted in a force-fitting manner above the eccentric.
In Fig. 1 ist ein Verbindungselement 1 perspektivisch dargestellt, das als schraubenlose Verbindungselemente über zwei Federelemente 2 verfügt. Die Federelemente 2 sind als U-förmige Winkelstücke ausgebildet, deren Traverse 3 jeweils als Formstück gestaltet ist. Mit diesem Formstück 3 ist das Federelement 2 jeweils in eine entsprechende Ausformung 4 des Verbindungselementes 1 unter Klemmwirkung eingesetzt. Je nach Bestückung des Verbindungselementes 1 mit ein oder zwei Federelementen 2 können auf das Verbindungselement ein oder zwei Baugruppenträger 5 aufgeschoben werden. Die U-förmig gestalteten Federelemente 2 verfügen zu diesem Zweck jeweils über unter Federspannung ausgestellte Federschenkel 6, die außenseitig in Aufschiebe- bzw. Aufsteckrichtung der Baugruppenträger 5 mit keilförmig versehenen Rastnasen 7 versehen sind. Beim Aufschieben oder Aufstecken der Baugruppenträger 5 auf das Verbindungselement 1 werden die Feder-In Fig. 1, a connecting element 1 is shown in perspective, which has two spring elements 2 as screwless connecting elements. The spring elements 2 are designed as U-shaped angle pieces, the crossbar 3 of which is each designed as a shaped piece. With this shaped piece 3, the spring element 2 is inserted into a corresponding shape 4 of the connecting element 1 under a clamping effect. Depending on whether the connecting element 1 is equipped with one or two spring elements 2, one or two module carriers 5 can be pushed onto the connecting element. For this purpose, the U-shaped spring elements 2 each have spring legs 6 that are extended under spring tension and which are provided with wedge-shaped locking lugs 7 on the outside in the sliding or plugging direction of the module carrier 5. When the module carrier 5 is pushed or plugged onto the connecting element 1, the spring
schenkel 6 an die Innenseiten der Baugruppenträger 5 gedruckt, bis sie mit ihren Rastnasen 7 in entsprechend korrespondierende Lochungen 8 im Baugruppenträger 5 einschnappen und dort zwischen Verbindungselement 1 und Baugruppenträger 5 eine kraftschlüssige Verbindung herstellen. Mittels eines Werkzeuges kann diese Verbindung jederzeit durch Eindrücken der Federschenkel und gleichzeitigem Zug an dem Baugruppenträger 5 gelöst werden. Diese Verbindung hat gegenüber einer Schraubverbindung durch beispielsweise vier Schrauben einen deutlich effektiveren Montage- und Demontagewert.legs 6 are pressed onto the inside of the subrack 5 until they snap into corresponding holes 8 in the subrack 5 with their locking lugs 7 and create a force-locking connection between the connecting element 1 and the subrack 5. Using a tool, this connection can be released at any time by pressing in the spring legs and simultaneously pulling on the subrack 5. This connection has a significantly more effective assembly and disassembly value than a screw connection using four screws, for example.
Fig. 2 zeigt eine neuerungsgemäße Verbindung von zwei Baugruppenträgern mittels eines Verbindungselementes mit Federelementen.Fig. 2 shows an innovative connection of two subracks using a connecting element with spring elements.
Fig. 3 stellt als Alternative ein U-förmiges Federelement 2 mit nach innen vorgespannten Federschenkeln 6 dar, zwischen denen ein Exzenter 9 angeordnet ist. Mit Hilfe dieses Exzenters 9 werden die Federschenkel 6 nach außen gedrückt (Fig. 4), wobei außen auf dem Schenkel 6 angebrachte Nocken 10 mit Lochungen 8 des zu verbindenden Teils 5 korrespondieren bzw. eine kraftschlüssige Verbindung herstellen. Das Lösen der Verbindungsstelle erfolgt durch Drehen des Exzenters in seine Entriegelungslage, wodurch sich die Nocken 10 aus den Lochungen 8 von 5 aufgrund der Federschenkelvorspannung zurückstellen.As an alternative, Fig. 3 shows a U-shaped spring element 2 with spring legs 6 pre-tensioned inwards, between which an eccentric 9 is arranged. With the help of this eccentric 9, the spring legs 6 are pressed outwards (Fig. 4), whereby cams 10 attached to the outside of the leg 6 correspond with holes 8 of the part 5 to be connected or create a force-fit connection. The connection point is released by turning the eccentric into its unlocking position, whereby the cams 10 move back out of the holes 8 of 5 due to the spring leg pre-tension.
