Stand der TechnikState of the art

Die Erfindung geht von einer Vorrichtung zum elektrischen Anschluß nach der Gattung des Patentanspruchs 1 aus. Bei einer durch die DE-A1-42 03 133 bekannten Vorrichtung zum elektrischen Anschluß zweier elektrischer Anschlußleiter sind an dem anzuschließenden elektrischen Gerät zwei Anschlußbolzen, die mit Schraubgewinde versehen sind, vorgesehen. Die Anschlußleiter münden je in ein Anschlußformteil, das eine langgezogene Öse aufweist, deren Mittellinie einer Kreisbahn folgt. Die Anschlußformteile liegen sich so gegenüber, daß die Ösen zueinander, bezogen auf einen geometrischen Mittelpunkt zwischen den Anschlußbolzen, sich diametral gegenüberliegen. Die Anschlußformteile werden durch einen Steg zusammengehalten derart, daß sich die Formteile mit einem dem Anschlußleiter folgenden Verlängerungsstück parallel zueinander liegen. Zur Herstellung der Verbindung werden die Ösen der Formteile über die Anschlußbolzen gestülpt, wobei der Winkel, unter den die Anschlußleiter zu dem elektrischen Gerät verlaufen, im Rahmen der Länge der Ösen verändert werden kann und danach durch Fixieren mit Befestigungsschrauben ein fixierter Kontakt mit dem elektrischen Gerät hergestellt wird. Mit Hilfe einer solchen Einrichtung können kleine Lageänderungen der Anschlußleiter zum elektrischen Gerät hergestellt werden.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In der Figur 1 ist ein Schnitt durch das erfindungsgemäße elektrische Gerät wiedergegeben. Auf einer Stirnseite eines elektrischen Gerätes, z. B. eines Magnetventils, ist ein Verschlußteil 1 vorgesehen, das das Magnetventilgehäuse 2 verschließt, dessen Rand 3 auf eine Schulter des Verschlußteils umgebördelt ist, so daß dieses fest im Magnetventilgehäuse gehalten wird. In dieses Verschlußteil aus Isolierstoff ist ein Befestigungszapfen 5 mit einem Fuß 6 mit Verankerungsprofil an seiner Umfangsfläche eingespritzt, wobei dieser Fuß 6 einen größten Durchmesser aufweist, an dem sich ein zylindrischer Teil 7 mit kleinerem Durchmesser anschließt, der zum Teil aus der Umspritzung des Verschlußteils stirnseitig nach außen ragt. Dieser zylindrische Teil bildet eine axial gerichtete gehäusefeste Schulter 8 aus, die in den endseitig mit einem Außengewinde versehenen Befestigungszapfen 5 übergeht. Durch das Verschlußteil werden ferner in Bohrungen 10 je ein Anschluß 11, 12, z.B. der Magnetspule des Magnetventils, axial nach außen geführt, von denen der eine Anschluß 11 über eine Klemm- oder Schweißverbindung mit einem ersten Anschlußelement 14 und der andere Anschluß 12 entsprechend mit einem zweiten Anschlußelement 15 kontaktiert ist. Diese Anschlußelemente sind ringförmig ausgebildet und mit ihrer Innenbohrung 16 bzw. 17 über den Befestigungszapfen geschoben. Das erste Anschlußelement 14 liegt dabei unmittelbar an der Schulter 8 als ebener Ring an. Ihm folgt dann ein ringförmiges Zwischenstück 18 aus Isoliermaterial und dann der ringförmige Teil des zweiten Anschlußelements 15, der stirnseitig auf dem ringförmigen Zwischenstück zur Anlage kommt und durch nicht weiter gezeigte Anschläge in radialer Distanz von den Befestigungszapfen gehalten wird. In Figure 1 is a section through the electrical according to the invention Device played. On an end face of an electrical Device, e.g. B. a solenoid valve, a closure part 1 is provided, that closes the solenoid valve housing 2, the edge of which 3 is flanged onto a shoulder of the closure part, so that this is held firmly in the solenoid valve housing. In this closure part made of insulating material is a mounting pin 5 with a Injected foot 6 with anchoring profile on its peripheral surface, this foot 6 has a largest diameter, on which there is a cylindrical part 7 with a smaller diameter connects, in part from the extrusion coating of the closure part protrudes towards the outside. This cylindrical part forms one axially directed housing-fixed shoulder 8, which in the end with an externally threaded fastening pin 5 transforms. Through the closure part are also in 10th bores one connection each 11, 12, e.g. the solenoid of the solenoid valve, guided axially outwards, of which one terminal 11 via a clamp or weld connection with a first connection element 14 and the other terminal 12 accordingly with a second Connection element 15 is contacted. These connectors are ring-shaped and with their inner bore 16 or 17 pushed over the mounting pin. The first connector 14 lies directly on the shoulder 8 as a level Ring on. It is followed by an annular intermediate piece 18 Insulating material and then the annular part of the second connection element 15, the face on the annular intermediate piece comes to the plant and by not shown Stops at a radial distance from the mounting pins is held.

Um die Anschlüsse 11 und 12 mit der Stromversorgung zu verbinden, ist weiterhin ein Anschlußstück 20 vorgesehen, in das ein erster Anschlußleiter 21 und ein zweiter Anschlußleiter 22 mit ihren Enden eingespritzt ist. Eingespritzt ist ferner ein erster Kontaktierungsfortsatz 24 eines ersten Anschlußkontaktes 26 und ein zweiter Kontaktierungsfortsatz 27 eines zweiten Anschlußkontakts 28. Die Kontaktierungsfortsätze stehen von einem ringförmigen Teil des jeweiligen Anschlußkontaktes ab, wobei die Außenränder 29 dieser ringförmigen Teile ebenfalls noch in das Anschlußstück eingespritzt sein können. Die ringförmigen Teile ragen innerhalb zweier benachbarter Radialebenen in eine axiale Ausnehmung 30 des Anschlußstückes hinein und sind voneinander durch ein Isolierteil 31 getrennt. Dieses ist mit seiner radial nach innen weisenden Stirnfläche 32 am Befestigungszapfen geführt und dient zugleich einer ersten Führung des Anschlußelements 20 am Befestigungszapfen 5. Der Innendurchmesser der ringförmigen Teile der Anschlußkontakte 26 und 28 ist größer als der Durchmesser des Befestigungszapfen und der Innendurchmesser der Stirnfläche 32 des Isolierteils, so daß es gewährleistet ist, daß die Anschlußkontakte nicht in Kontakt mit dem aus elektrisch leitendem Material hergestellten Befestigungszapfen 5 kommen.To connect ports 11 and 12 to the power supply, a connector 20 is also provided in the first lead 21 and a second lead 22 with their ends are injected. A first is also injected Contacting extension 24 of a first connection contact 26 and a second contact extension 27 of a second connection contact 28. The contacting processes stand out from an annular Part of the respective contact from, the outer edges 29 of these annular parts also still in the connector can be injected. The ring-shaped parts protrude within two adjacent radial planes into an axial one Recess 30 of the connector and are from each other separated by an insulating part 31. This is radial with its inwardly facing end surface 32 on the mounting pin and also serves as a first guide for the connection element 20 on the mounting pin 5. The inner diameter of the annular Parts of the contacts 26 and 28 is larger than that Diameter of the mounting pin and the inside diameter of the End face 32 of the insulating part, so that it is ensured that the contacts are not in contact with the electrical conductive material produced mounting pin 5 come.

Durch ein auf den Befestigungszapfen axial aufgeschraubtes Schraubteil 34, das im ausgeführten Beispiel eine Mutter aus elektrisch leitendem Material ist, werden einerseits der erste Anschlußkontakt zusammen mit dem zweiten Anschlußkontakt zur Anlage an das zweite Anschlußelement 15 gebracht, wodurch wiederum das erste Anschlußelement 14 zur festen kontaktierenden Anlage an der Schulter 8 gehalten wird. Das Schraubteil hat dazu eine auf den zweiten Anschlußkontakt 28 aufsetzende Stirnseite 33, die zur besseren Kontaktierung und auch zur Selbstsicherung mit einer Riffelung versehen sein kann. Somit wird der zweite Anschlagsleiter 22 über zweiten Anschlußkontakt 28, das Schraubteil 34, den Befestigungszapfen 5 und das erste Anschlußelement 14 mit dem Anschluß 11 verbunden und der erste Anschlußleiter 21 über das zweite Anschlußelement 15 mit dem Anschluß 12 verbunden.By an axially screwed onto the mounting pin Screw part 34, the nut in the example shown electrically conductive material, will be the first on the one hand Connection contact together with the second connection contact to the system brought to the second connection element 15, which in turn the first connection element 14 for fixed contacting system is held on the shoulder 8. The screw part has one on the second connection contact 28 face 33 those for better contacting and also for self-assurance can be corrugated. Thus, the second attack leader 22 via second connection contact 28, the screw part 34, the mounting pin 5 and the first connection element 14 connected to the terminal 11 and the first connecting conductor 21st connected to the connection 12 via the second connection element 15.

Das Anschlußteil 20 hat ferner eine das Verschlußteil übergreifende ringmantelförmige Wandung 37, die auf ihrer Innenseite Formschlußflächen mit in Achsrichtung des Befestigungsbolzen verlaufendem Profil 38 aufweist. Dieses Profil kann eine Verzahnung sein mit in Umfangsrichtung weisenden Flanken, welche Verzahnung in eine entsprechende Gegenverzahnung 39 am Außenumfang des Verschlußteils eingreift. Mit diesen Formschlußflächen 38 bzw. 39 mit regelmäßig in Umfangsrichtung fortschreitendem Profil kann nun das Anschlußstück in sehr feiner Unterteilung in verschiedene Drehstellungen auf das Verschlußteil aufgesteckt werden und somit in Umfangsdrehrichtung in einer bestimmten gewünschten Drehstellung fixiert werden. Nach diesem Aufstecken erfolgt dann das Aufschrauben des Schraubteils 34, nachdem bei dem Aufsteckvorgang des Anschlußstückes die Anschlußkontakte und Anschlußelemente aufgefädelt waren. Nachdem das Anschlußstück durch das Verschrauben mit dem Schraubteil 34 fixiert ist, kann die axiale Ausnehmung noch durch einen Stopfen 40, der in die Ausnehmung eingepreßt, eingeklebt oder eingeschraubt werden kann, verschlossen werden. Auf diese Weise können die abgehenden Anschlußleiter in einer gewünschten Winkelstellung zum Magnetventilgehäuse abgeführt werden. In einfacher Weise erfolgt nach dem Aufstecken des Anschlußstückes mit einem einfachen Schraubvorgang die Kontaktierung beider Anschlußleiter mit den Anschlüssen des Magnetventils, was die Montage sehr vereinfacht und auch eine automatische Montage zuläßt. The connecting part 20 also has a cross-over the closure part ring-shaped wall 37 on the inside Form-locking surfaces with in the axial direction of the fastening bolt extending profile 38. This profile can be interlocking be with circumferential flanks, what serration in a corresponding counter-toothing 39 on the outer circumference of the closure part engages. With these interlocking surfaces 38 or 39 with a profile progressing regularly in the circumferential direction can now the connector in a very fine division different rotary positions attached to the closure part be and thus in the circumferential direction of rotation in a certain desired Rotational position can be fixed. After this attachment the screw part 34 is then screwed on after at the plugging process of the connector, the contacts and Connection elements were threaded. After the connector is fixed by screwing with the screw 34 the axial recess through a stopper 40, which in the Recess pressed in, glued in or screwed in can be closed. This way the outgoing Connection conductor in a desired angular position to the solenoid valve housing be dissipated. It is done in a simple manner the attachment of the connector with a simple screwing the contacting of both connection conductors with the connections of the solenoid valve, which greatly simplifies assembly and also allows automatic assembly.

In der Figur 2 ist in der Draufsicht das auf eine Verteilereinspritzpumpe 41 mit Magnetventil 42 aufgeschraubte Anschlußstück 20 dargestellt. Man erkennt hier die V-förmige Zusammenführung der Anschlußleiter zu einem gemeinsam ummantelten Kabel 43, das zwischen Einspritzleitungen 44 abführt.FIG. 2 is a top view of a distributor injection pump 41 with solenoid valve 42 screwed on connector 20 shown.
