Description

Die Erfindung bezieht sich auf einen codierbaren Steckverbinder mit einem ersten und einem zweiten Steckerteil mit derartig angeordneten Codierstücken, dass nur Steckerteile mit aneinander angepasster Anordnung der Codierstücke zusammenfügbar sind, und mit schwenkbarer Halterung des zweiten Steckerteils am ersten Steckerteil, wobei durch eine Schwenkbewegung ein Aneinanderfügen bzw. Voneinanderentfernen der Steckerteile bewirkt wird.The invention relates to a codable plug connector with a first and a second plug part with coding pieces arranged in such a way that only plug parts with a mutually adapted arrangement of the coding pieces can be joined together, and with a pivotable mounting of the second plug part on the first plug part, with a swiveling movement joining or Removing the connector parts from one another is effected.

Bei einem bekannten Steckverbinder dieser Art (DE-A-2 849 077) sind die beiden Steckerteile mittels einer Befestigungsnase an dem ersten Steckerteil und mittels eines Befestigungshakens am zweiten Steckerteil miteinander derart verbindbar, dass das zweite Steckerteil schwenkbar am ersten Steckerteil gehalten ist. Voraussetzung für die Verbindung der beiden Steckerteile miteinander ist, dass eine Ausnehmung an der Befestigungsnase zu einem Ansatz an dem Befestigungshaken passt. Eine weiter Codiereinrichtung ist von einem Codierstift am ersten Steckerteil und einer weiteren Ausnehmung am Befestigungshaken des zweiten Steckerteils gebildet.In a known plug connector of this type (DE-A-2 849 077), the two plug parts can be connected to one another by means of a fastening lug on the first plug part and by means of a fastening hook on the second plug part such that the second plug part is pivotably held on the first plug part. A prerequisite for the connection of the two plug parts to one another is that a recess on the fastening lug matches an attachment on the fastening hook. Another coding device is formed by a coding pin on the first plug part and a further recess on the fastening hook of the second plug part.

Bei einem anderen bekannten Steckverbinder (DE-B-2 807 017) sind im Bereich der Kontaktelemente an beiden Steckerteilen an verschiedenen Stellen Codierstücke angebracht. Die Anordnung der Codierstücke ist an beiden Steckerteilen derart aneinander angepasst, dass nur ein Zusammenfügen jeweils gleich codierter Steckerteile möglich ist. Die Vorsprünge bzw. Ausnehmungen der jeweiligen Codierstücke erstrecken sich hierbei in der Ausrichtung der Kontaktelemente, so dass die beiden passenden Steckerteile mit zueinander parallel verlaufenden Frontflächen ineinander gesteckt werden.In another known connector (DE-B-2 807 017) coding pieces are attached to the two connector parts at different points in the area of the contact elements. The arrangement of the coding pieces on both plug parts is adapted to one another in such a way that only the same coded plug parts can be joined together. The projections or recesses of the respective coding pieces extend in the alignment of the contact elements, so that the two matching plug parts with mutually parallel front surfaces are inserted into one another.

Der Erfindung liegt die Aufgabe zugrunde, einen codierbaren Steckverbinder mit einem an einem ersten Steckerteil schwenkbar gelagerten zweiten Steckerteil zu schaffen, der sich hinsichtlich der die Codierung bewirkenden Ausgestaltung kostengünstig herstellen lässt.The invention has for its object to provide a codable connector with a second connector part pivotably mounted on a first connector part, which can be produced inexpensively in terms of the configuration causing the coding.

Zur Lösung dieser Aufgabe ist bei einem codierbaren Steckverbinder der eingangs genannten Art erfindungsgemäss das zweite Steckerteil auf einer Drehachse des ersten Steckerteils drehbar gelagert, und im Bereich der Drehachse ist jeweils eines der Codierstücke am ersten und am zweiten Steckerteil austauschbar angeordnet; an den parallel zur Drehachse verlaufenden, sich gegenüberliegenden Flächen der beiden Codierstücke sind Ausnehmungen bzw. Vorsprünge angebracht, die beim Schwenken des zweiten Steckerteils um die Drehachse ineinandergreifen.To achieve this object, according to the invention, in a codable connector of the type mentioned at the outset, the second connector part is rotatably mounted on an axis of rotation of the first connector part, and in the region of the axis of rotation one of the coding pieces is arranged interchangeably on the first and on the second connector part; On the mutually parallel surfaces of the two coding pieces, which run parallel to the axis of rotation, there are recesses or projections which engage when the second plug part is pivoted about the axis of rotation.

Der erfindungsgemässe Steckverbinder ist insofern vorteilhaft, als bei ihm der Vorteil einer sicheren Verhinderung des Zusammensteckens nicht zusammengehöriger Steckerteile bereits im Anfangsstadium aufgrund der Anbringung der Codierstücke im Bereich der drehbaren Halterung mit dem Vorteil der Verwendung durchgehend gleicher erster und zweiter Steckerteile verbunden ist, weil zur unterschiedlichen Codierung an jedem Steckerteil nur jeweils ein Codierstück mit jeweils entsprechender Codierung anzubringen ist. Dadurch kann auch ein Austausch der Codierstücke auf einfache Weise vorgenommen werden. Durch die Lagerung des zweiten Steckerteils auf der Drehachse ergibt sich der weitere Vorteil, dass die Schwenkbewegung des zweiten Steckerteils gut geführt erfolgt, so dass Codierstücke mit vergleichsweise engen Toleranzen Anwendung finden können, wodurch die Anzahl der Codiermöglichkeiten bei gleichen Abmessungen relativ hoch ist.The connector according to the invention is advantageous in that it has the advantage of reliably preventing plug-in connector parts from being plugged together already in the initial stage due to the attachment of the coding pieces in the region of the rotatable holder, with the advantage of using the same first and second connector parts throughout, because they differ Coding only one coding piece with the appropriate coding is to be attached to each connector part. As a result, the coding pieces can also be exchanged in a simple manner. The storage of the second connector part on the axis of rotation results in the further advantage that the pivoting movement of the second connector part takes place in a well-guided manner, so that coding pieces with comparatively narrow tolerances can be used, whereby the number of coding options is relatively high with the same dimensions.

Um ein möglichst dichtes Ineinandergreifen der beiden Codierstücke zu ermöglichen, sind die sich gegenüberliegenden Flächen der Codierstücke zylinder- bzw. hohlzylinderförmig mit der Drehachse als Zylinderachse ausgebildet. Das Codierstück im drehbaren zweiten Steckerteil ist hierbei an der der Drehachse abgewandten Seite zylinderförmig und das am ersten Steckerteil gegenüberliegende zweite Codierstück ist an der dem ersten Codierstück zugewandten Seite hohlzylinderförmig ausgebildet, so dass die beiden sich gegenüberliegenden Flächen bei einer Drehung des zweiten Steckerteils aneinandergleiten können.In order to enable the two coding pieces to mesh as closely as possible, the opposing surfaces of the coding pieces are cylindrical or hollow-cylindrical with the axis of rotation as the cylinder axis. The coding piece in the rotatable second plug part is cylindrical on the side facing away from the axis of rotation and the second coding piece on the first plug part opposite is hollow cylindrical on the side facing the first coding piece, so that the two opposite surfaces can slide against each other when the second plug part rotates.

Um einen einfachen Austausch der Codierstücke an den Steckerteilen zu ermöglichen, weisen die Codierstücke Befestigungszapfen auf, mit denen sie in entsprechende Ausnehmungen am ersten bzw. zweiten Steckerteil einschnappbar sind.In order to enable simple exchange of the coding pieces on the plug parts, the coding pieces have fastening pins with which they can be snapped into corresponding recesses on the first or second plug part.

Am Halterahmen 3 ist eine Drehachse 7 angebracht, die teilweise von einem Haken 8 des zweiten Steckerteils 2 umgriffen wird. Das zweite Steckerteil 2 weist Kontaktelemente 9 auf, die in ertsprechende Kontaktelemente im Teil 6 des ersten Steckerteils 1 eingreifen.FIG. 1 shows a plug connector with a first plug part 1 and a second plug part 2. The first plug part 1 consists of a holding frame 3, which is fastened to a housing of an electrical device 5 via pins 4, and a part 6, which contains the contact elements for the plug connection. An axis of rotation 7 is attached to the holding frame 3 and is partially encompassed by a hook 8 of the second plug part 2. The second plug part 2 has contact elements 9 which engage in corresponding contact elements in part 6 of the first plug part 1.

Weiterhin sind bei der Darstellung nach der Figur 1 Befestigungslöcher 10, 11 zur Aufnahme von Codierstücken 15, 19 - die anhand der Figur 2 näher erläutert werden - am zweiten Steckerteil 2 vorhanden. Am gegenüberliegenden Ende des Steckverbinders befinden sich Teile einer Verriegelungsvorrichtung 12, mittels der die beiden Steckerteile 1 und 2 miteinander verriegelt werden können.Furthermore, in the illustration according to FIG. 1, fastening holes 10, 11 for receiving coding pieces 15, 19 — which are explained in more detail with reference to FIG. 2 — are provided on the second plug part 2. At the opposite end of the connector are parts of a locking device 12, by means of which the two connector parts 1 and 2 can be locked together.

In der Figur 2 ist das Codierstück 15 am zweiten Steckerteil 2 detailliert dargestellt, wobei das Codierstück 15 über Befestigungszapfen 16 und 17 in den Befestigungslöchern 10, 11 des zweiten Steckerteils 2 gehalten ist. An einer Fläche 18 ist das Codierstück 15 derart abgerundet, dass sie einen Teil einer Zylinderfläche mit der Drehachse 7 als Zylinderachse darstellt. Das Codierstück 19 ist als entsprechendes Gegenstück am Steckerteil 1 angebracht. Die dem ersten Codierstück 1 zugewandten Flächen 20 des Codierstücks 19 sind hohlzylinderförmig ausgebildet.2 shows the coding piece 15 on the second plug part 2 in detail, the coding piece 15 being held in the fastening holes 10, 11 of the second plug part 2 by means of fastening pins 16 and 17. The coding piece 15 is rounded on a surface 18 in such a way that it represents part of a cylinder surface with the axis of rotation 7 as the cylinder axis. The coding piece 19 is a corresponding counterpart on the connector part 1 brings. The surfaces 20 of the coding piece 19 facing the first coding piece 1 are hollow-cylindrical.

Die Figuren 3 bis 6 zeigen weitere Detaildarstellungen der Codierstücke 15 und 19, wobei insbesondere die Schnittdarstellungen in den Figuren 4 und 6 die Lage der Codierungen auf den Flächen 18 und 20 der Codierstücke 15 und 19 zeigen. Hierbei ist insbesondere ein Vorsprung 21 am Codierstück 15 erkennbar, der in eine entsprechende Ausnehmung 22 am Codierstück 19 beim Zusammenfügen der beiden Steckerteile 1 und 2 eingreift. Die Lage des Vorsprungs 21 bzw. der Ausnehmung 22 wird entsprechend einer bestimmten Codierung vorgegeben, durch die nur jeweils zusammengehörige Steckerteile ineinandergesteckt werden können. Durch einfache Drehung der Codierstücke 15 und 19 um eine Achse 23 kann mit denselben Codierstücken eine weitere Codierung hergestellt werden, ohne hierfür andere Codierstücke herzustellen. Zur Halterung im Steckerteil 1 weist das zweite Codierstück 19 Zapfen 24 auf, die in entsprechende Ausnehmungen am ersten Steckerteil 1 eingreifen.FIGS. 3 to 6 show further detailed representations of the coding pieces 15 and 19, the sectional representations in FIGS. 4 and 6 in particular showing the position of the coding on the surfaces 18 and 20 of the coding pieces 15 and 19.
