• - Plug type C, CEE 7/17, contour plug, without protective conductor
• - Plug type E, CEE 7/5, with earth conductor
• - Plug type F, CEE 7/4, earthing contact plug, with protective conductor
• - Plug type E + F, CEE 7/7, combination plug, with protective conductor.

With them devices - mainly household and workshop equipment - of protection class I (with protective earth connection) and protection class II (without protective earth connection) can be connected to the predominantly 240 V (-10% ... + 5%) / 50 Hz power supply. The non-reconnectable plugs are overmoulded with the connecting cable; the reconnectable plug have a mostly hollow cylindrical insulating material with screw or spring plug terminal connection for power, zero and possibly protective earth connection and have a pronounced strain relief for the connecting cable. The connection cables are usually guided parallel to the plug contacts in the axial direction of the connector housing; But there are also connectors with lateral, extending in the radial direction cable entry available on the market. The adapter version is the shortest design of earthing contact plug and coupling in combination.

• – es sind Kontaktabstände – wie Luft- und Kriechstrecken – einzuhalten
• – der Abstand zum Schutzleiter ist zu gewährleisten
• – der Installationsraum – oft nur einmal benötigt – muß gut zugänglich sein
• – der Anschlußraum muß die längere PE-Leitung aufnehmen
• – die Anschlußkontakte müssen den Steck- oder Anschraubkräften standhalten
• – das Steckergehäuse muß mechanisch verriegelt und elektrisch isoliert sein
• – das Steckergehäuse darf nur mittels eines Werkzeugs zu öffnen sein
• – oft verbindet eine Zylinderschraube die beiden Gehäusehälften.

Due to many requirements, the connector housing appear relatively large volume

• - Contact distances - such as clearances and creepage distances - must be observed
• - The distance to the protective conductor must be ensured
• - The installation space - often needed only once - must be easily accessible
• - The terminal compartment must accommodate the longer PE line
• - The connection contacts must withstand the plugging or Anschraubkräften
• - The connector housing must be mechanically locked and electrically isolated
• - The plug housing may only be opened by means of a tool
• - Often a cylinder screw connects the two housing halves.

A portion of the plug housing dives into the plug receptacle of the socket in the plugged state, but a large part of the plug or the plug housing protrudes from the socket, both in axial and radial cable entry. With axial cable entry, there is still a greater need for space around the socket, since the bending radius of the connecting cable adds up to the distance to the wall. In the adapter version protrudes in the plugged state, the plug receptacle of the coupling part from the socket.

• – gestaltet sich einerseits die Handhabung des Kabelanschlusses schwierig,
• – artet andererseits die manuelle Bedienung dahingehend aus, daß eine Trennung des Steckers mit der Steckdose nur ganz schwierig zu vollziehen ist, da das überragende Steckergehäuse des steckdosengesteckten Steckers zu wenig Greifvolumen bietet und dann der Stecker über das Anschlußkabel und die Zugentlastung unzulässig aus der Steckdose entfernt wird und
• – wird bei der Adapter-Ausführung ein Gerätestecker aus der Adapter-Kupplung entfernt, kann – je nach den Kräfteverhältnissen der Steckverbindungen – auch der Adapter ungewollt mit aus der Steckdose entfernt werden.

On the other hand, if, on the other hand, attempts are made to minimize the connection volume of the plug housing to standard specifications,

• On the one hand the handling of the cable connection is difficult,
• - Artet other hand, the manual operation to the effect that a separation of the plug with the socket is only very difficult to perform, since the superior connector housing of the plug-socket connector offers too little gripping volume and then the plug on the cable and the strain relief inadmissible removed from the socket will and
• - If an adapter plug is removed from the adapter coupling in the adapter design can - depending on the balance of power of the connectors - and the adapter unintentionally be removed from the socket.

In the following, the state of the art of comfort connectors - especially of power plugs for household and workshop equipment technology in adapter design with plug and coupling, with ease of use and designed also for multiple sockets - appreciated; According to the prior art, depending on the application, a variety of types of comfort plugs - in particular of power plugs for home appliance technology in adapter design, with ease of use, designed for multi-outlet sockets, in use.

• a) einerseits die Trennung bewirkende Druckkraft direkt oder indirekt über einen Mechanismus des Steckers auf die Steckdose und
• b) andererseits Zugkraft auf einen Schenkel eines in Höhe der Kontaktstifte gelagerten äußeren Hebels, dessen abgewinkelter anderer Schenkel einen die Trennung bewirkenden Druck zwischen Stecker und Steckdose ausübt.

The French registration FR 2 641 651 is devoted to several examples of mechanically assisted pulling of household electrical plugs from sockets. The introduction of. Is planned

• a) on the one hand, the separation causing compressive force directly or indirectly via a mechanism of the plug to the socket and
• b) on the other hand tensile force on a leg of an outer lever mounted in the amount of the pins whose angled other leg exerts a separation causing pressure between the plug and socket.

To a) The inside of the plug to a push pin o. Ä. To supplement has the consequence that the plug must be repeatedly tested for compliance with valid electrical standards and certified; It is imperative to observe the observance of distances, clearances and creepage distances. A not centered to the pins mounted lifting device leads to jamming in the loosening attempt. When lifting devices for plug type E sockets with the above grounding or protective conductor pin acting on the same, have an asymmetric force distribution under pressure - the plug jammed in the plug receptacle of the socket during the removal attempt. In such arrangements, the necessary grounding or protective conductor with the E + F types of connector collide with such a lifting device usually.

To b) An outside z. B. on an angle plug parallel to the cable connection lever attached, the remote from the cable leg is supported on a 90 ° bend on the frame and the other leg is pronounced as a manually operated access must have plugged plug a pivot bearing perpendicular to the cable connection, whose axis of rotation is in a plane spanned by the contact pins plane and parallel to the bottom of the pot. Upon manual actuation of the pull handle, the center line of the rotation axis changes its position from the plane defined by the contact pins plane away on a sub-cylinder whose radius is formed by the distance of the center line to the support point of the opposite leg. The Drehachslager must be performed in the lever or in the plug as a floating bearing, the plug should not jam by means of the contact pins and / or in the plug receptacle of the socket during the release attempt. A mandatory according to the contact pin arrangement axially parallel plug / socket removal is in contradiction to the change in position of the axis of rotation in the lever movement with one-sided support. A loose or sliding bearing between the lever and plug leads to a significant reduction in the perceived value of the device and can also lead to slipping in the frame support - Comparison lever corkscrew.

According to the European patent EP 1 071 169 'Electrical Plug Device' is a 3-pin plug for a Schuko plug and a 2-pin plug for a standard socket presented. The special feature is designed as a lever bracket designed to facilitate the removal of the plug from the socket. It is striking that the bracket of the plug for the socket outlet is diagonally arranged between on the one hand a safety contact and on the other hand a guide lip, probably the structural conditions such as those of compliance with the creepage distances and creeping bill. Another special feature is that the pivot point of the bracket is arranged asymmetrically. Both peculiarities - especially in the Schuko version - cause the lever forces translated during actuation of the bracket not only have an effect in the direction of the axial contact pin extension, but also have force components perpendicular thereto, with the bracket / lever continuing to pull away grow.

These power components lead when plugged in to the fact that both the pins in their recording and - at least when Schuko plug - tilt the lips in their leadership and the - in itself - nullify helping removal property. The wandering of the point of traction between the bracket / lever and the supporting socket surface is shown in the figures 5 and 6 especially clear.

According to the publication DE 10 2004 022 189 is proposed an electrical socket outlet for Unterputzeinbau with respect to the conventional socket outlet recessed plug socket. The inventive socket with recessed plug pot is to take the inserted plug with angled cable connection in full height in itself, so that the wall side prevails between the cover frame surface and connector side flush. For the purpose of handling the plug, a flexible handle or strap is proposed, which also serves the child safety. The plug cable connection thus runs in a recess of the cover frame.

It is hard to imagine that the industry standard 'socket outlet' with countless, worldwide installed connections due to a special installation falls; it has to be searched for compatibility solutions.

Offenlegungsschrift DE 10 2006 029 927 provides an elastomeric angled connector of the connector type F for an electrical appliance connection in the household and in the workshop, which has a device that converts a wall facing away train on a connected to the angle plug power cable such that a pressing out of the angle plug is effected from the socket. If an overmolded conventional connection plug combination provided with a kink protection is attempted to pull the plug out of the socket by pulling on the connection cable, the force distribution acting on the contact pins not paraxial prevents the success of this handling; Damaged cable, plug or socket are the result. The present innovation therefore provides a 90 ° lever element mounted asymmetrically in the angled connector, one leg of which is extended in the direction of the connecting cable and the second leg of which is parallel to the axis of the bottom surface of the Plug receptacle of the socket shows and penetrates the opposite plug head end face and with this - in rest - flush ends. A cable connection side, wall facing away from actuation of the lever causes rotation and the other leg emerges from the plug head end face and acts on the plug receptacle of the socket, that the angle plug is released from the socket.

Prerequisite for the function is an accurate introduction of force of the fulcrum in the amount of the plug contact pins, otherwise jamming or distortion of the plug in the socket is the result. The mechanical introduction of a rotatably mounted lever within an electrical angle plug must not affect the electrical properties - such as creepage distances, etc. - of the same. In addition to the geometric position of the contact pins, the guide or the position of the protective conductor connections or a protective conductor strap must also be taken into account.

According to the patent DE 10 2007 045 400 a flat-fitting power plug is proposed, the terminal compartment has been moved to outside the cover of the socket, the plug part of the plug are connected to the connector pins and the outer cable connection space via contact plates, which are provided in the terminal compartment with screw terminals. The plug part and a plate form the main body, which is closed at the back, on the side facing away from the wall with a lid. In the area of the terminal compartment, an insulating cover with cable strain relief is additionally used on the wall side. The plug height outside the socket receptacle of the socket is determined by the height of the structure or the thickness of the plastic plate with the inserted contact plates and the thickness of the plastic lid in the range of the cover of the socket and is in the range of about 5 mm. Further embodiments show that the cable connection space is reduced to a cable insertion space, wherein the connecting wires are guided in place of the contact plates to the contact pins supplemented by terminals. Another embodiment shows the plug variant with molded, not reconnectable plug. By dimensioning the plug on the frame dimensions of the socket when using a multiple combination only the external sockets come as slots in question. The guide of the connecting cable is invariably 90 ° angled downwards. The connector can - without jamming - only be inserted axially parallel to the pins and pulled; when pulling an auxiliary device by means of a handle or a tab is necessary. A lever for the purpose of plug removal at the cable connection point can attack the body on the upper socket frame and leads only to tilting and distortion of the body.

With the disclosure DE 10 2008 045 191 discloses a flat device power plug type E + F, the lack of handling of the connector of the application DE 10 2007 045 400 to eliminate. The external appearance of the old and new connectors are essentially the same; the handling of an according to the contact pin arrangement axis-parallel plug removal is achieved in that the connector body is arranged by about 15 ° from the center position upwardly pivotally mounted on the connector housing by means of rotary bearings. When plugged a wall facing away train on the plug housing in the region of the cable connection space leads to the cable connection space opposite end of the plug housing forming a cantilever is supported on the cover of the socket, the plug housing changed in further train from its wall-parallel position to an angular position and about the pivot bearing, the connector body with the pins removed from the socket. In this case, the end of the plug housing forming a cantilever also changes its position on the cover frame of the socket to its center around the difference in length between the axis-parallel coordinate and the angular offset produced by the rotation. The asymmetric arrangement of the connector housing to the contact pins with upper end / boom to lower end / cable connection space of about 3: 8, according to the leverage laws, a correspondingly less effort for plug removal result. The plug is designed for 250 V / 16 A.

The cable connection compartment is only used for strain relief; The cable must be stripped and strain relieved, the cable cores in the connector housing out and the wires are connected to the contact pins. The cable cores perform the pivoting movements of the body. The cable outlet is at vertical connector mounting down. The plug can be contacted because of its protruding cable connection space on the socket frame dimensions only in the end boxes of a multiple socket arrangement. When the plug is removed, the main body has no preferred position relative to the plug housing; The location may be determined by the connected cable cores.

According to the European patent EP 2 672 574 is a comfort flat plug - especially a power plug for household and Werkstattgerätetechnik in flat design, presented with ease of use and designed for multiple arranged sockets.

The comfort tab according to the invention does not build on the plane dimensions of the cover frame and not on the pitches in multiple-socket arrangements, so that each slot of a combination can be contacted with the plug. Likewise, the plug-in direction of the plug is optional. The tab has a cable outlet in three directions when mounted vertically, so that the cable is guided without kinks even at 90 ° twisted or diagonally mounted sockets. For ease of use of the tab has a plug housing superior horseshoe-shaped rotatably mounted bracket with a recessed grip at the top and a lever action, with the help of wall facing away train below the axis of rotation protruding leg ends of the bracket against the cover of the flush-mounted outlet and push the plugged Lever out of its final position.

• – un-/vergossene Anschlußstecker fertig am Elektrogerät oder
• – konfektionierte Kabellängen mit Anschlußstecker montiert geliefert werden und ein Austausch des Anschlußsteckers aus Gründen des Komforts nur selten stattfindet; darüber hinaus muß ein gewünschter Austausch durch eine Elektrofachkraft erfolgen.

This publication stands for a variety of similar applications, all of which share the common disadvantage that

• - Un- / molded connector finished on the electrical device or
• - Assembled cable lengths are delivered with connector mounted and replacement of the connector takes place for reasons of comfort only rarely; In addition, a desired replacement must be done by a qualified electrician.

With the German disclosure DE 40 16 768 is a grounding Universal connector is disclosed, the cable entry in the lower rear, the pins opposite range from axial to angle plug is convertible and beyond its rear side, above, has access for a two-pin euro or tab, when not in use a spring-mounted flap is closed.

The plug corresponds in its illustrated form not the usual safety regulations, since in the case of a plug-socket connector, the still exposed connector pins of a not yet fully inserted Euro or flat connector already represent live parts. A comfort help is not provided.

With the US patent application US 2003/0181 082 a multi-function plug adapter - consisting of two-pin plug, coupling and appliance plug 'razor' - known, the supply side via either swing-out connector combinations for a flat pin and a round pin connection (Euro plug) has, the supply side opposite a two-pole multiple-connector coupling and also a plurality of contactless openings for receiving differently arranged center pins and also a connection line with a 'razor' device connector.

The contactless openings for receiving differently arranged center pins of connectors is problematic because it is an electrically isolated receptacle 'placeholder', but the user expects contact-type nulling or a protective ground that does not exist in the bipolar supply.

Furthermore, a comfort help is not provided.

The utility model DE 203 02 136 provides an electrical adapter for at least a two-pin euro or flat plug, which consists of a protective contact plug part for commercial under- (UP) - or surface-mounted (AP) sockets and on the rear side, the pins opposite an electrical receptacle body for Euro - Or flat connector has at right angles to the pins, which does not build higher than a euro or flat plug plus two security wall thicknesses.

A comfort help is not provided.

The German utility model DE 20 2004 005 617 provides a safety plug as an adapter, which allows 90 ° offset on its rear side, the connection of several two-pin Euro or flat plug.

The older utility model DE 203 02 136 provides for the connection of at least one two-pin Euro or flat plug in the same position.

In the relevant trade, a Series 8822 plug-in remover is offered which consists of a substantially two-piece swing mechanism with a 'fixed' annular member slipped over a grounding plug and positioned at the plug-in terminal end of the protective contact, while a second annular lever-shaped part passes over the outer diameter of the first part is zweipunktdrehbargelagert, so that a so-equipped and positioned in a socket outlet safety plug via a manual train causes a leverage of the outer ring member on the socket cover, forcing the safety plug with the pivoting mechanism from the socket. The swing mechanism works with axial as well as with angle plugs and is reusable.

Since both the spring contacts of the earthing contact socket and the contact pins of the corresponding connector in the length and in their insertion depth are standardized, stands by the Slipping the swivel mechanism over the plug no longer provides the standardized insertion depth of the protective contact connection and represents a safety violation relating to safety.
