Definitions

• the invention relates to a power plug for plugging into a power socket, with a plug body and at least two plug contacts of different standards, which each have two electrically conductive contact pins and can be pushed into an active position from the plug body and can be pushed into a passive position into the plug body.
• a multiple adapter plug with four plug contacts is known.
• the plug contacts are arranged one above the other in a drawer-like manner and can be pushed into and pushed out of the plug body.
• This multiple adapter plug has a first plug contact, which, depending on the position of the contact pins, can correspond to the US and Australian standards, a second, which, depending on the position of the plug contact, can correspond to the standards of Germany or other European countries, and a third, that of the British standard , and a fourth that complies with the Italian standard.
• the British plug contact has two contact pins at the bottom of the plug body and an opener without electrical contact at the top of the plug body.
• Three other sliding plug contacts are arranged between the opener and the contact pins of the British plug contact. So that the opener of the British plug contact hangs together with the contact pins, the other plug contacts have a central slot running in the sliding direction, through which a connecting web extends between the plug contacts and the opener.
• the displaceable plug contacts of the other standards are divided in half along an axis of symmetry of the plug except for a connecting bridge between one and the other half.
• An actuating lever is resiliently arranged on each of these halves.
• actuating levers are displaceable in slots formed on both sides of the housing and engage in an active position of the plug contact on the housing.
• the British plug contact has two actuating levers in the axis of symmetry of the plug, which latch into the housing in the same way.
• the actuating levers of a plug contact lock this plug contact in its active or passive
• a socket is formed on the back of the plug.
• the electrical connection from plug contact to socket takes place via two U-shaped conductors, which are connected to the contact sockets of the socket.
• Conductive sliders are formed on the plug contacts which, depending on the plug contact, slide either on the inside or the outside on one of the two legs of the U-shaped conductor.
• a disadvantage of this connector is that several plug contacts can be pushed out of the housing at the same time. Another disadvantage is that all plug contacts are below the supply voltage as soon as a plug contact is connected to a power source.
• the plug contact for Germany has an insulated plug body protruding from the plug body in the active position, from which the contact pins protrude. If this plug contact is e.g. plugged into a socket in Spain without the recess corresponding to the plug-in body, another plug contact advanced is freely accessible and is live.
• a mains plug for plugging into a mains socket has a housing and at least two plug contacts of different standards, which are displaceably mounted in the housing. These plug contacts each have at least two electrically conductive contact pins.
• the plug contacts can be moved into an active position and a passive position. The contact pins can be pushed out of the housing into the active position and into the housing into the passive position.
• the stated object is achieved in that a locking device that is movable relative to the housing and cooperates with the plug contacts is provided, which opens the sliding path from the passive to the active position for a single plug contact in different positions.
• the locking device blocks the sliding path for the other plug-in contacts, since the mobility of the locking device is restricted by the plug-in contact outside of the passive position in such a way that the pushing of a further plug-in contact from the passive into the active position is prevented by the locking device held in the sliding path of the other plug-in contact is.
• the locking device can e.g. be formed by a rotatable disc, which in different rotational positions releases the perforation for a single plug contact and covers the other perforations.
• the locking device preferably has a number of locking bodies which can be moved independently of one another and are arranged and guided next to one another.
• the dimensions of these locking bodies and their freedom of movement are such that only a single extension on a carrier part, advantageously the actuating lever of a single plug contact, is accommodated in one of the spaces between the switching parts.
• the locking bodies lie tightly against one another in the other intermediate spaces and thus prevent a further extension from being able to be guided between the locking bodies. This makes it impossible for more than one plug contact to be in the active position.
• the locking bodies are advantageously identical, so
• the locking body can be pivotally mounted or straight. They are advantageously guided on a circular path.
• the locking bodies are advantageously arranged within the housing. Since they are expediently guided through the housing wall on one side, the circular path is expedient for the shape of the housing. The shift in a leadership has compared to that
• Swiveling around an axis has the advantage that the parts and their space requirements are smaller.
• connection conductors in the case of a power plug with connection conductors mentioned in the interior of the housing for the electrical connection of further electrical connecting parts to the contact pins the connection conductors in the case of a power plug with connection conductors mentioned in the interior of the housing for the electrical connection of further electrical connecting parts to the contact pins
• Active position of a plug contact are each electrically connected to a contact pin, and are electrically separated from the contact pin in the passive position of the plug contact.
• the contact between the connecting conductor and the contact pin is also advantageously interrupted in a position of the plug contact between the active position and the passive control. This makes it impossible to connect a power supply via an incorrectly inserted plug contact. This significantly reduces the risk of fire due to a spark jump in the mains socket.
• Two band-shaped connecting conductors are advantageously arranged on the housing on the inside of the plug surface and paraUel for this purpose, which interact with contacts, which are electrically connected to the contact pins of the plug contacts, via terminals.
• the terminals are advantageously formed on the connecting conductor and the contact holders of the contact pins are inserted into these terminals when pushed into the active position.
• the plug contacts are advantageously locked in this position by the safety body.
• each plug contact has a carrier part on which the contact pins are arranged. On the carrier parts or on the euro plug-in body, a contact surface which is approximately conical from the side of the active control to the side of the passive position is advantageously formed for each contact pin.
• contacts connected to the connecting conductor are pressed against the contact pins by the contact surfaces.
• the tapered design of the contact surfaces allows the contact holders to be resilient and the spring force to make the contact holders pushes away from the contact pin. This ensures that the contacts outside the guide surfaces are no longer in contact with the contact pins.
• the contactors are advantageously each combined with a plug socket and, e.g. connected by a welding spot. This allows the use of two identical contacts and two identical plug sockets, each of which are joined together differently.
• An overload protection device is therefore advantageously provided in the mains plug. This is in particular arranged between a plug contact corresponding to the European standard and the further connecting parts. However, other plug contacts can also be protected. Furthermore, the risk of accidents with the power plug can be significantly reduced by providing a single safety body in the power plug, which can move between a release and a fixation control and which in the fixation control supports every plug contact in the active control to prevent the plug contact from being accidentally pushed into the passive control guaranteed. The safety body therefore fixes the pushed-out plug contact in the active control, which ensures correct contact between the contact pins and the mains connection in a socket into which the plug is inserted.
• the task controlled at the outset is achieved in that an inside of the housing has a
• this single safety body allows the plug contact to be pushed and at the same time narrows or closes at least one insertion opening. This makes it impossible to plug in a power supply as long as the plug contact is not in the active control. This also makes it impossible to draw power from an incorrectly inserted plug contact.
• the safety body is advantageously mounted displaceably by a displacement distance and has a number of holding rods arranged transversely to the displacement direction. The holding rods cooperate with a guide side of the holding rods directed transversely to the sliding direction with the carrier parts of the plug contacts. A cut end point is formed on this guide side at the front and rear.
• a thickening protruding with respect to the end units is formed between the cut end units.
• the protrusion of this thickening is at most the length of the displacement distance of the security body.
• the front end control interacts with the carrier part of the extended plug contact
• the passive position of the plug contact the rear end control interacts with its carrier part. This ensures that the safety body is in the release position when there is a plug contact between the active and passive controls.
• the thickening towards the rear end control is diluted obliquely down to the level of the end control.
• the rear end point can, however, also be designed in such a way that a stop prevents the plug contact from advancing if it is not pressed from the outside of the release control. So that the plug contact is secured in the active control, the thickening towards the front end control has a section directed towards the sliding direction.
• the safety body has one to unlock a plug contact located in the active control
• the safety body which is resiliently mounted in relation to the housing, can be pressed from the fixation position into the release position with the actuation button.

• the opener 45 and the contact pins 43 of the UK plug contact thus form a guide for the carrier parts of the US or AU plug contact.
• the EU plug contact is guided within the plug-in body 31.
• the UK plug contact is in turn guided on the housing 13, 15.
• FIGS. 30 to 34 show the views of the second exemplary embodiment, which essentially have no changes compared to the views of the first exemplary embodiment. The only difference is the supplementary rib 201 in FIGS. 32, 33 and 34, the recess 203 in FIG. 31 and the fact that the actuation bolts 27c and 27d have been changed.
• the outermost actuating pin 27d is for actuating the UK plug contact, the second 27c for actuating the US plug contact.
• the travel plug set according to FIGS. 34 to 42 is a preferred exemplary embodiment.
• the multiple plug of this set differs from the multiple plug according to FIGS. 1 to 23 in the type of contact between the plug contacts and the connecting conductor.
• the plug connector corresponds to that shown in FIG. 26.
• the plug contact 140 according to the US standard is therefore arranged between NC 45 and 43 Divisti 43 of the UK plug contact 144.
• the multiple socket 103 has a locking mechanism for the UK socket, which in a known manner releases the sockets for UK plug contacts after inserting the opener into the opening provided for the opener.
• the locking mechanism is explained below with reference to FIG. 38.
• the multiple socket 103 fits volumetrically into the recess of the multiple plug 11 and forms a flat socket with insertion openings for UK, US and AU plugs. Since the multiple plug has an EU-compatible socket, it is not necessary to operate this standard with the multiple socket, even if this would be possible without further ado.
• the perforated brothers of the individual standards are pushed into each other in such a way that no insertion opening overlaps with another insertion opening.
• the multiple socket 103 For plugging into the multiple plug 11, the multiple socket 103 has two connecting pins 107 which fit into the socket of the multiple plug 11.
• a latching lug 109 is soldered onto at least one of the connecting pins 107.
• the snap lug 109 makes it impossible to plug the multiple socket into a socket of a national or regional standard. Therefore, it is possible to continuously fill in the insertion openings, so that the bottom of the socket 21 on the multiple plug is closed.
• the opener of an inserted UK plug even extends into the recess 203 in the base of the socket.
• FIG. 37 the parts of the multiple connector 11 are shown in an exploded view. Corresponding parts are designated as in FIG. 6, even if the parts have a different shape. Compared to the parts in the corresponding illustration in FIG. 6, the following parts are shaped significantly differently:
• the removable fuse compartment 47 according to FIG. 6 now consists of a fuse compartment 47 provided in the interior of the multiple plug 11 and a closure cover 147.
• the fuse compartment 47 is flattened in the base part 13 ( see Fig. 42).
• An overload protection device 67 is arranged therein.
• the fuse compartment 47 is surrounded by a central body 111.
• the plug-in sockets 73.75 are accommodated in the central body.
• the central body 111 is clamped between the cover 15 and the base part 13.
• the electrical connection parts between the connecting conductors 171, 172, the plug-in sockets 73, 75 and the overload protection 67 are accommodated in the central body 111.
• the displaceably mounted plug contacts are arranged outside the central body.
• the overload protection device 67 is connected in such a way that all plug contacts are protected.
• the metal part forming the plug-in socket 75 is inserted in a connecting conductor 172, while the metal part forming the other plug-in socket 73 is in contact with the rear end of the overload protection device 67.
• the part 113 making this connection is in prestress, and therefore incorrectly with the Overload protection shown overlapping.
• the front end of the overload protection device 67 is in contact with an insert 115 in the closure cover 147, which insert 115 comes into contact with the connecting conductor 171 when the closure cover 147 is screwed into the main part 13.
• the insertion body 35 is guided in a dovetail 135 in the basic part 13.
• a driver 139 is formed on the EU plug contact 138, which withdraws the plug-in body 35 when the EU plug contact 138 is moved from the active to the passive control.
• the security body 81 is also guided with a dovetail on the cover 15.
• FIGS. 39 to 41 An improved contact between the plug contacts 138, 140, 142 and 144 and the connecting conductors 171, 172 on the plug-side housing wall is shown in FIGS. 39 to 41.
• the connecting conductors 171 and 172 are pressed with the central body 111 against the housing wall.
• the connection conductors 171 and 172 each have 4 terminals 175. These terminals 175 have an insertion area and a clamping area.
• Two contacts 177, one for each contact pin 39, are soldered onto the plug contacts, or their support parts 38, 40, 42 and 44 (only US plug contact 140 with the support part 40 is shown). These contact holders 177 are in electrical connection with a contact pin 39. When the plug contact 140 is advanced, the contact holders 177 come into the terminals 175 at the end of the sliding movement.
• the contact holder 177 can enter the terminal 175 against a small clamping resistance be introduced.
• the clamping force of clamp 175 safely controls the electrical connection.
• this is only the case with a plug contact in the active control (Fig. 41).
• the plug contact in the passive control (FIG. 40) connecting conductors 171, 172 and the contacts 177 are always separated.
• the multiple socket is composed of a plug part 181, a socket part 182 and a slide 185, and the electrically conductive parts.
• Two connector pins 107 are soldered onto the connector part 181.
• the connection pins are made of plastic.
• a current collector 183 is inserted into a cavity in its interior. This establishes the connection to the inserted plugs.
• a contact spring is soldered to each pantograph 183 for each insertion opening. These sit in the sockets and contact the inserted contact pins on one Side of the contact pin.
• a slide 185 is displaceably mounted between the plug-in sockets formed in the plug assembly 181. This slide 185 covers the insertion openings according to the UK standard. The opener of a UK plug presses against an inclined sliding surface on the slide 185 when pushed in and pushes it against the force of a spring 187 integrally molded on the slide from the position closing the openings for the UK contact pins.
• a reserve overload protection device 167 is also accommodated in the multiple socket 103.
• the travel plug set is shown plugged together. It can be seen in this figure that the latching lug 109 snaps onto the rear wall 87 of the security body 81.
• the electrical connections from the connecting conductors 171, 172 via the overload protection device 67 to the plug-in sockets according to the US standard, as already described, can also be seen.
• the continuity of the insertion openings from the front of the multiple socket to the rear of the multiple socket can also be seen.
• 43 and 44 schematically show two extended travel plug sets.
• the multiple plug 11 is shown on the left, here with only three sliding plug contacts.
• One of two plug-in sockets 73, 75 is shown opposite the slide-out plug contacts.
• the contact pins 189 or connecting pins of the voltage converter 191 can be inserted into these plug-in sockets 73, 75.
• the voltage inside the voltage converter is changed.
• the voltage converter may measure the voltage of the connected power network and automatically switch to a set voltage. This desired voltage is connected to the plug-in sockets of the voltage converter. This can now be tapped with the connecting pins 107 of the multiple socket 103 and is available in the plug-in sockets of the multiple socket.
• the voltage converter can also be combined with a current converter. This is shown in FIG. 44.
• a direct current connection 195 for a low-voltage consumer is present on the current converter 193.
• the voltage of the outgoing direct current is adjustable.
• the current transformer 193 has no plug-in sockets for the multiple socket 103, but only a direct current low-voltage connection 195.
• the current transformer also has a DC connection a plug-in socket, which is connected to the voltage that taps the multiple plug 11 in the mains socket. In this case, the current converter 193 and a voltage converter 191 can be connected in series.
• Connection pins of the multiple socket for plugging into the socket of the Multiple plug
