Description

Die vorliegende Erfindung bezieht sich auf eine Halterung für eine im Steckerkörper eines elektrischen Netzsteckers integrierte Ringkerndrossel nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a holder for a toroidal inductor integrated in the plug body of an electrical mains plug according to the preamble of patent claim 1.

Ein Netzstecker mit einer integrierten Halterung bzw. Aufnahme für die stromkompensierte Ringkerndrossel ist in Verbindung mit einem sogenannten Zentralstecker aus der DE-A- 34 40 573 bekannt. Unter einem Zentralstecker versteht man dabei einen Netzstecker, bei dem die Kontakthülsen zur Aufnahme der Stromleiteradern eines Anschlußkabels und die dem Steckerkörper gegenüber vorstehenden Steckerstifte koaxial zueinander orientiert sind.A power plug with an integrated holder or receptacle for the current-compensated toroidal choke is known in connection with a so-called central plug from DE-A-34 40 573. A central plug is understood to mean a mains plug in which the contact sleeves for receiving the current conductors of a connecting cable and the plug pins projecting from the plug body are oriented coaxially to one another.

Zentralstecker der bekannten und genannten Art stehen, wenn sie in die Steckdose eines Stromversorgungsnetzes eingesteckt sind, relativ weit in den Raum hinein; demzufolge steht auch das über den Netzstecker mit Energie zu versorgende Gerät relativ weit von der Steckdose und damit von der Wand, in der die Steckdose installiert ist, ab.Central plugs of the known and mentioned type are relatively far into the room when they are plugged into the socket of a power supply network; consequently, the device to be supplied with power via the mains plug also projects relatively far from the socket and thus from the wall in which the socket is installed.

Um diese Unzulänglichkeit zu minimieren, wurden sogenannte Winkelstecker konzipiert. Dabei handelt es sich um einen Netzstecker, bei dem die genannten Kontakthülsen relativ zu den Steckerstiften so orientiert sind, daß sie einen Winkel von 90 Grad einschließen. Das im Steckerkörper mit den Kontakthülsen verbundene Anschlußkabel verläuft somit bei in die Steckdose gestecktem Winkelstecker parallel zur Wand; der Winkelstecker reicht demzufolge weit weniger tief in den Raum hinein wie der Zentralstecker.So-called angled plugs were designed to minimize this inadequacy. It is a power plug in which the said contact sleeves are oriented relative to the connector pins so that they are one Include 90 degree angles. The connecting cable connected in the plug body to the contact sleeves thus runs parallel to the wall when the angled plug is inserted into the socket; the angled plug therefore extends far less deep into the room than the central plug.

Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht darin, eine Halterung der gattungsgemäßen Art anzugeben, die gleichermaßen zur Herstellung von Zentral- und und von Winkelsteckern geeignet ist. Diese Stecker bestehen bekanntlich aus einem einstückigen Spritzteil, das einerseits die Steckerstifte und andererseits die mit den Stromleitern eines Anschlußkabels verbundenen Kontakthülsen umfaßt, wobei sich zwischen der Steckerbrücke für die Steckerstifte und dem Quersteg für die Kontakthülsen die Halterung für die Ringkerndrossel erstreckt. Dieses Spritzteil wird in einer geeigneten Form so mit Kunststoff umspritzt, daß sich ein Griff- oder Steckerkörper ergibt, von dem einerseits die Steckerstifte vorstehen und andererseits- und zwar je nach Ausführungsform - das Anschlußkabel koaxial (Zentralstecker) oder um 90 Grad abgewinkelt (Winkelstecker) absteht.The object on which the present invention is based is to specify a holder of the generic type which is equally suitable for producing central and angled plugs. These plugs are known to consist of a one-piece molded part which on the one hand comprises the plug pins and on the other hand the contact sleeves connected to the current conductors of a connecting cable, the holder for the toroidal core choke extending between the plug bridge for the plug pins and the crossbar for the contact sleeves. This molded part is overmolded in a suitable form with plastic so that a handle or connector body results, from which the connector pins protrude on the one hand and, depending on the embodiment, on the other hand - the connection cable is coaxial (central connector) or angled by 90 degrees (angled connector) protrudes.

Die Lösung der vorgenannten Aufgabe besteht darin, daß die Halterung am Quersteg für die Kontakthülsen nach Art eines Klappscharniers angelenkt ist.The solution to the above problem is that the bracket is articulated on the crossbar for the contact sleeves in the manner of a folding hinge.

Damit kann also, je nachdem ob Zentral- oder Winkelstecker gefertigt werden sollen, der Quersteg mit den Kontakthülsen axial zu den Steckerstiften oder abgewinkelt hierzu positioniert werden. Dies ist in einfacher Weise dadurch möglich, daß der Quersteg mit der Halterung über ein Filmgelenk verbunden ist (Patentanspruch 2). Zur Vereinfachung des Herstellungsvorgangs sind am Quersteg und an der Halterung zueinander komplementäre Verriegelungsmittel vorgesehen (Patentanspruch 3), über die der Quersteg in der jeweils richtigen Stellung positioniert werden kann.Depending on whether central or angled plugs are to be manufactured, the cross bar with the contact sleeves can thus be positioned axially to the plug pins or at an angle to it. This is possible in a simple manner in that the crossbar is connected to the holder via a film joint (claim 2). To simplify the manufacturing process, complementary locking means are provided on the crossbar and on the holder (claim 3), via which the crossbar in the correct position can be positioned.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in

Fig. 1
- und zwar in drei teilweise geschnittenen Ansichten - ein aus einer Steckerbrücke, einer Halterung und einem Quersteg bestehendes einstückiges Spritzteil für einen Zentralstecker;
Fig. 2
die Seitenansicht des Spritzteils nach Fig.1 in dessen Orientierung für einen Winkelstecker.
The invention is explained below with reference to the drawing. This shows in
Fig. 1
- In three partially sectioned views - a one-piece molded part for a central plug consisting of a plug bridge, a holder and a crossbar;
Fig. 2
the side view of the molded part of Figure 1 in its orientation for an angled connector.

Das einstückige Spritzteil nach Fig. 1 umfaßt eine Art Grundplatte als Steckerbrücke 1, in die in genormtem, einer Steckdose entsprechenden Abstand, zwei (genormte) Steckerstifte 2 eingespritzt sind. An die Steckerbrücke 1 schließt mittig über einen (ersten) Steg 3 eine im wesentliche runde Platte 4 an, die als Halterung bzw. Aufnahme für eine - strichpunktiert angedeutete - Ringkerndrossel 5 dient. An den zum Steg 3 diametralen Umfangsteil der Platte 4 schließt ein zweiter Steg 6 an, der seinerseits mit einem Quersteg 7 verbunden ist. In diesen Quersteg 7 sind form- und kraftschlüssig zwei Kontakthülsen 8 eingesetzt, mit denen beispielsweise über eine Quetsch- oder Crimpverbindung die - nicht gezeichneten - Stromleiteranschlüsse eines Anschlußkabels verbunden werden.The one-piece molded part according to FIG. 1 comprises a type of base plate as a plug bridge 1, into which two (standardized) plug pins 2 are injected at a standardized distance corresponding to a socket. An essentially round plate 4, which serves as a holder or receptacle for a toroidal core choke 5, indicated by dash-dotted lines, connects to the connector bridge 1 in the center via a (first) web 3. A second web 6 adjoins the peripheral part of the plate 4 which is diametrical to the web 3 and which is in turn connected to a cross web 7. In this crosspiece 7, two contact sleeves 8 are inserted in a form-fitting and non-positive manner, with which, for example via a crimp or crimp connection, the - not shown - current conductor connections of a connecting cable are connected.

Die Ringkerndrossel 5 liegt in einer Vertiefung der runden Platte 4 und wird über Hakenelemente 9 arretiert. Die Kontakthülse 8 und die Steckerstifte 2 sind jeweils paarweise über eine - gestrichelt angedeutete - Spule 10 miteinander verbunden, so daß damit in einem fertigen Netzstecker eine stromkompensierte Ringkerndrossel 5 integriert ist.The toroidal core choke 5 lies in a recess in the round plate 4 and is locked in place by means of hook elements 9. The contact sleeve 8 and the connector pins 2 are each connected in pairs via a - indicated by dashed lines - coil 10, so that a current-compensated toroidal choke 5 is integrated into a finished power plug.

Die soweit beschriebene Halterung für die Ringkerndrossel 5 bzw. der soweit beschriebene Zentralstecker ist Stand der Technik. Der vorliegenden Erfindung gemäß ist der Quersteg 7 mit der runden Platte 4 nach Art eines Klappscharniers, insbesondere über eine Art Filmgelenk 11 verbunden, d.h. der zweite Steg 6 ist so dünn ausgebildet, daß er ein Filmgelenk 11 bildet. Damit kann der Quersteg 7 mit den Kontakthülsen 8 entsprechend der Seitenansicht nach Fig. 1 gerade ausgerichtet werden oder er kann auch - entsprechend der Fig. 2 - um 90 Grad abgewinkelt werden (vgl. Pfeil X).The holder for the toroidal choke 5 or the central plug described so far is state of the art. According to the present invention, the crosspiece 7 is connected to the round plate 4 in the manner of a folding hinge, in particular via a type of film joint 11, i.e. the second web 6 is so thin that it forms a film joint 11. The crossbar 7 can thus be aligned with the contact sleeves 8 in accordance with the side view according to FIG. 1, or it can also - according to FIG. 2 - be angled by 90 degrees (cf. arrow X).

Da die in Fig. 1 und Fig. 2 dargestellten Baueinheiten in einer geeigneten Spritzform mit Kunststoff umspritzt werden, empfiehlt es sich, am Quersteg 7 und an der runden Platte 4 zueinander komplementäre Verriegelungsmittel vorzusehen. Damit läßt sich der Quersteg 7 in der jeweils richtigen Ausrichtung zur runden Platte 4 hin einclipsen.Since the structural units shown in FIGS. 1 and 2 are encapsulated with plastic in a suitable injection mold, it is advisable to provide complementary locking means on the crosspiece 7 and on the round plate 4. This allows the crossbar 7 to be clipped in the correct orientation to the round plate 4.
