Description
Die Erfindung betrifft eine Anordnung zum elektrischen Verbinden eines ersten und eines zweiten Anschlussmittels. Darüber hinaus betrifft die Erfindung ein Automatisierungsgerät gemäß dem Oberbegriff des Anspruchs 8 und ferner eine Baugruppe gemäß dem Oberbegriff des Anspruchs 15, welche zum Anschluss an ein derartiges Automatisierungsgerät geeignet ist.The invention relates to an arrangement for electrically connecting a first and a second connection means. In addition, the invention relates to an automation device according to the preamble of
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art zu schaffen, welche eine verbesserte Kontaktierung der Anschlussmittel ermöglicht. Ferner ist ein Automatisierungsgerät der eingangs genannten Art mit einer verbesserten Kontaktierung der Baugruppe mit einem elektrischen Potential des Baugruppenträgers des Automatisierungsgerätes anzugeben. Darüber hinaus ist eine Baugruppe der eingangs genannten Art zu schaffen, welche für einen Einsatz in einem derartigen Automatisierungsgerät geeignet ist.The present invention has for its object to provide an arrangement of the type mentioned, which allows improved contacting of the connection means. Furthermore, an automation device of the aforementioned Specify type with an improved contacting of the module with an electrical potential of the rack of the programmable controller. In addition, an assembly of the aforementioned type is to be created, which is suitable for use in such an automation device.
Diese Aufgabe wird im Hinblick auf die Anordnung mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen, im Hinblick auf das Automatisierungsgerät mit den im kennzeichnenden Teil des Anspruchs 8 angegebenen und im Hinblick auf die Baugruppe mit den im kennzeichnenden Teil des Anspruchs 15 angegebenen Maßnahmen gelöst.This object is achieved in view of the arrangement with the specified in the characterizing part of claim 1, in view of the programmable controller with the specified in the characterizing part of
Vorteilhaft ist eine langfristig zuverlässige Kontaktqualität aufgrund der Vielzahl der Kontaktstellen in Form von metallischen Borsten. Mit anderen Worten: Durch die große Anzahl der Kontaktstellen sind Aussagen über maximale Kontaktverluste sowie über minimalen Kontaktwiderstand möglich. Darüber hinaus wird durch derartige Anschlussmittel die thermische Verlustleistung sehr gut abgeführt. Die Borsten-Anschlussmittel sind als Bürsten ausgestaltet, welche in verschiedenen Formen, z. B. in Form von Rund-, Topf- oder Kegelbürsten, oder in einer sonstigen geeigneten Form ausgebildet sein können.A long-term reliable contact quality is advantageous due to the large number of contact points in the form of metallic bristles. In other words: Due to the large number of contact points, statements about maximum contact losses as well as minimal contact resistance are possible. In addition, the thermal power loss is very well dissipated by such connection means. The bristle connection means are designed as brushes which in various forms, for. B. in the form of round, pot or cone brushes, or may be formed in any other suitable form.
In einer Ausgestaltung der Erfindung gemäß den im Anspruch 2 angegebenen Maßnahmen wird eine einfache bzw. im Falle einer wellenförmigen Ausbildung der Borsten eine sehr gute Kontaktierung im Hinblick auf die Anzahl der möglichen Kontaktstellen erzielt. Werden die Anschlussmittel zusammengesteckt, greifen die Borsten ineinander ein und verhaken sich gegenseitig.In one embodiment of the invention according to the measures specified in
In einer weiteren Ausgestaltung der Erfindung sind die Borsten klettverschlussartig ausgebildet, wodurch die Kontaktierung der Borsten weiter verbessert wird. Die Borsten beider Anschlussmittel weisen dazu an ihren Enden Häkchen auf, die beim Zusammenstecken der Anschlussmittel ineinander greifen. Um die Borsten klettverschlussartig auszubilden, können auch die Enden der Borsten nur eines Anschlussmittels mit Häkchen und die Enden der Borsten des zweiten Anschlussmittels mit Schlaufen versehen sein.In a further embodiment of the invention, the bristles are formed like velcro, whereby the contacting of the bristles is further improved. The bristles of both connection means have to check at their ends, the when mating the connection means interlock. In order to form the bristles in the manner of a velcro, the ends of the bristles of only one connection means with hooks and the ends of the bristles of the second connection means can also be provided with loops.
In einer weiteren Ausgestaltung der Erfindung sind gemäß den im Anspruch 5 angegebenen Maßnahmen das erste und/oder das zweite Anschlussmittel als Borstenschiene ausgebildet. Eine derartige Borstenschiene ist für einen Einsatz in einem Baugruppenträger eines Automatisierungsgerätes als Massepotentialschiene geeignet. Selbstverständlich ist es möglich, z. B. mittels zweier derartiger Borstenschienen einen Stromversorgungsbus auf dem Baugruppenträger des Automatisierungsgerätes zu verwirklichen.In a further embodiment of the invention, according to the measures specified in
Dadurch, dass das Anschlussmittel zum Schutz der Borsten mit einer Schutzhülle bzw. einem Schutzgehäuse versehen ist, wird verhindert, dass die Borsten zu stark verbogen werden. Darüber hinaus ist gewährleistet, dass die Verletzungsgefahr für einen Anwender im Wesentlichen ausgeschlossen ist.The fact that the connection means for protecting the bristles is provided with a protective casing or a protective housing, prevents the bristles are bent too much. In addition, it is ensured that the risk of injury to a user is essentially excluded.
Vorteilhaft ist die Schutzhülle des Anschlussmittels zu den Borsten axial beweglich ausgebildet. Wird das Anschlussmittel eingesteckt, verschiebt sich die Schutzhülle entgegen der Einsteckrichtung. Beim Lösen des Anschlussmittels verschiebt sich die Schutzhülle über die Borsten, wodurch die Borsten, welche sich während des Einsteckens zu stark verbogen haben, sich im Wesentlichen wieder gerade biegen.Advantageously, the protective cover of the connection means is designed to be axially movable with respect to the bristles. If the connection means plugged in, the protective sheath moves against the direction of insertion. Upon release of the connection means, the protective sheath shifts over the bristles, whereby the bristles, which have bent too much during the insertion, essentially bend straight again.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the other dependent claims.

Um zu verhindern, dass die Borsten 12, 13 während der Kontaktierung zu stark verbogen werden, und um weitgehend zu gewährleisten, dass die Verletzungsgefahr für einen Anwender ausgeschlossen ist, weisen die Borstenschiene 11 und die Bürste 14 Schutzhüllen 15, 16 auf, von denen die Schutzhülle 15 der Bürstenschiene 11 starr und die Schutzhülle der Bürste 14 beweglich ausgebildet ist (
Im vorliegenden Ausführungsbeispiel sind beide Anschlussmittel 11, 14 mit einer Vielzahl von elektrisch leitenden Borsten 12, 13 ausgebildet. Für den Fall, dass die Anforderungen im Hinblick auf eine gute Kontaktierung nicht so hoch sind, ist es ausreichend, lediglich ein Anschlussmittel mit einer Vielzahl von Borsten zu versehen. Das andere Anschlussmittel kann in diesem Fall eine metallische Schiene, eine schräge Wand oder eine Röhre sein.In the present embodiment, both connection means 11, 14 are formed with a plurality of electrically
