Abstract

A travel plug comprises a socket on one side for one or several plug types. On the opposite side several pin contacts (for example, 138) of various types may be extended into an operating position. The pin contacts (for example, 138) may be extended in slide slots (25a,b,c,d) by means of operating levers (27a,b,c,d). Said slide slots (25) for the non-extended pin contacts are covered by stop bodies (29), such that just one single pin contact (for example, 138) may be extended. A safety body (81), which secures the pin contact (138) in the active position prevents the extended pin contact (138) from being inadvertently pushed back.

Description

power plug

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.

State of the art:

From US-A-4,626,052 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. As a result, 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. These 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

BESTÄTIGUΝGSKOPIE Position, but have no influence on the sliding ability of another plug contact.

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.

If a plug contact is not fully pushed into the active end position, the actuating lever on the housing does not engage. However, the plug contact can still be inserted. The contact in the socket is then no longer ensured. An electrical device plugged into the socket in the multiple adapter plug can still be used. Repeated sparking within the socket, heating of the socket and consequently a fire can easily occur.

Object of the invention:

It is the object of the invention to propose a mains plug with a plurality of plug contacts which can be pushed out, in which the risk of accidents is considerably reduced compared to the prior art. Description of the invention:

According to the invention, this object is achieved in the case of a power plug in that the parts that may be live are covered, or in that a power supply is only possible via a fully extended plug contact. 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. In the case of such a connector, 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. At the same time, 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. As a result, 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

^J τι__ _rt _ τ_ ^j - "ι - π."",""«._Λ; _{M Λ} T7 _< -M _* -r ι io iΛ in- xi _K rirr 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.

One solution to the problem is that 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

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. In another embodiment of this contacting in the active position, 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. In the active position of the plug-in contact, 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.

If the power plug is a transition plug with a power socket for plugging in a power plug of one or more specific standards, 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.

Due to the tapering arrangement of the contact pins, a maximum load on the Euro plug is required to avoid sparking in the socket.

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.

If the power plug itself has at least one socket with at least two insertion openings for inserting a power plug into the housing, the task controlled at the outset is achieved in that an inside of the housing has a

Release and a fixation control of movable safety bodies are provided. In the release control, 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. In the active control the front end control interacts with the carrier part of the extended plug contact, in 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.

So that the safety body is automatically brought into the release position when a plug-in contact is pushed out, 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

Actuation button that protrudes through an opening in the housing. 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 spring force pushes it into the fixation control. Brief description of the figures:

Detailed description of the figures:

The multiple connector according to Figures 1 to 23 is a first embodiment of a multiple connector for a travel connector set. The exemplary embodiment shown has four plug contacts of different standards, which can be moved into and out of the housing and a socket for two plug standards, namely US and EU. The socket can also be designed for a connector standard other than that shown, for a single connector or for more than two.

The housing 13, 15 is shown in FIG. The housing is composed of a main part 13 and a cover 15. The side shown is called the actuating side 17, the upper side is the socket side 19 with a recess, at the bottom of which a hole pattern of a socket 21 is formed. Slide actuators 25 are formed on the actuation side 17, through which the actuation bolts 27 protrude and can be displaced from the outside in the longitudinal direction of the protector. The locking bodies 29 are visible through the sliding protectors 25. Figure 2 shows the connector surface 31, which is arranged opposite the socket side 19. In the main part 13 is the plug surface 31 with the through openings 33 for the euro plug-in body 35 with the EU contact pins 37, the contact pins 39, 41 and 43 of the US, AU and UK plug contacts and the electrically non-connected opener 45 of the UK - Plug contact formed. A removable fuse compartment 47 is also provided in the plug surface 31.

The can side 19 is shown in FIG. In the bottom of the recess, the hole block is designed for a US and an EU plug. Behind the insertion holes 49 for the contact pins of these plugs there are provided sockets 73, 75, with which inserted contact pins are in electrical contact. In the base and in the edge 53 of the recess, latching means 55 are provided which interact with an add-on for the travel plug. In Figure 3, a guide 57 for a guide pin 59 is visible on the security body described later. FIG. 4 shows the release side 61 of the travel plug, which lies opposite the actuation side 13. Deviating from the basic cylindrical shape of the travel connector, its outer shape on the release side is increasingly worn towards the connector surface. This results in a surface 63 which is oblique to the direction of insertion of the travel plug. In this surface 63 there is an opening through which a push button or actuation button 65 protrudes. The pusher is part of the security body. By pressing the pusher 65, the safety body can be displaced in accordance with the scope that the guide 57 grants to the guide pin 59. Thanks to the bevel of the surface 63, the safety body can be inserted into the main unit 13 from the open can side 19. The pusher 65 slides along the inside of the housing wall and falls into the opening provided in the inclined surface 63.

FIG. 5 shows the actuating side 17 with the sliding slots 25 and the actuating bolts of the four plug contacts protruding through them. The longest sliding slot 25a is provided for the EU plug contact. In the adjacent sliding slot 25b is the actuating pin 27b of the UK plug contact. The actuating bolt 27c of the AU plug contact is visible in the adjoining sliding slot 25c and lastly the actuating bolt 27d of the US plug contact is visible in the sliding slot 25d. The locking bodies 29 are visible through the sliding block 25.

FIG. 6 shows an overview of the part of the travel plug. The housing 13, 15 consists of a main part 13 and a cover 15. The main part and cover complement each other and enclose all moving parts and the electrically conductive parts. When the housing 13, 15 is closed, only the fuse compartment 47 and the fuse 67 present therein can be removed.

The three locking bodies 29 are arranged in the interior of the housing 13, 15. These are displaceably mounted on a circular arc along the wall of the main part 13 and block three of the four sliding contactors 25 each. Furthermore, a euro plug-in body 35 is accommodated in the housing 13, 15. The EU contact pins 37 of the EU plug contact 38 are mounted displaceably in the euro plug-in body 35. The euro plug-in body 35 has contactors through which the connecting conductors 69 and 71 are guided to the EU contact pins 37. Another connection conductor 70 is not led to an EU contact pin. The connecting conductor 71 connects the one plug socket 73 to a contact pin of each plug contact that is in active control. The contact pin 69 connects single one side of the fuse 67 with the other EU plug contact 37. The other side of the fuse is connected to the other socket 75. A connection of the second contact pins of the UK, AU and US plug contacts is ensured with the connection conductor 70. In a simplified version without a fuse, two identically shaped connecting conductors 71 can be used, each of which is connected in the opposite way to one of the plug sockets 73, 75. In the assembled state of the travel plug, the connection conductors lie directly on the inside of the plug surface 31 and touch the contact pins of the plug contact which has been brought into the active position. FIG. 7 shows this inside of the plug surface 31 on the main part 13 with the connecting conductors 69, 70, 71. At the top we find the holes 139 for the contact pins 39 of the US plug contact. Between these, the two connection conductors 71 and 70 are each arranged at a short distance from a hole 139. When the US plug contact is advanced, the connecting conductors 71, 70 are brought into contact with the US contact pins 39. The connecting conductors 71, 70 are then guided to the outside of the holes 141 of the AU contact pins 41 in order to tangentially touch the holes 143 of the UK contact pins 41 on the inside thereof. The one connecting conductor 70 ends at this point. The other connection conductor 71 is guided into the euro plug-in body 35 on the outside of the one hole 137 for the EU contact pins 37. The connecting conductor 69 is also guided from the fuse compartment 47 through a slot in the wall of the euro plug-in body 35 and into the outside of the other hole 137 for the other EU contact pin 37. The fuse 67 is in contact with the connecting conductor 70 via a pickup 77 on the fuse compartment 47. This electrical connection is established by screwing the fuse compartment 47 into the main part 13 or interrupted by unscrewing it.

Returning to FIG. 6, further parts accommodated in the housing 13, 15 are to be described. The EU contact pins 37 are arranged on an EU carrier part 38 and together with this form the EU plug contact 138. The contact pins 43 arranged on the UK carrier part 44 and the opener 45 together with the carrier part 44 form the UK plug contact 144. The Opener 45 can be made of plastic or MetaU. The AU contact pins 41 together with the AU carrier part 42 form the AU plug contact 142 and the US contact pins with the US carrier part on which they are arranged are the US plug contact 140. The carrier parts 38, 40, 42, 44 are guided with the actuating bolts 27 in the slide contactors 25 in the main part 13. In addition, the carrier parts 40, 42, 44 are guided on guide rods 79 visible in FIG. 7. For this purpose, the cylindrical guide rods 79 protrude through round holes 78 (FIG. 16) which are drilled out in the carrier parts. The euro insertion body 35 is guided in a similar manner on a rod 80. The EU plug contact 137 is guided on the euro plug-in body 35 with guide lugs 82 (FIG. 16).

Holding rods 83 are formed on a safety body 81. The holding rods 83 secure the plug contact which is in the active control from being inadvertently pushed back out of the active control. For this purpose, the safety body 81 is spring-mounted. The spring 85 presses the safety body into its initial position, in which it secures the active position of a plug contact. From this position, it can be pressed against the spring force, so that the plug contact which is in active control can then be pushed into the housing 13, 15.

Figures 8 to 11 show the travel plug with one of the four plug contacts in active control. In FIG. 8 the EU plug contact 138, in FIG. 9 the AU plug contact 142, in FIG. 10 the UK plug contact 144 and in FIG. 11 the US plug contact 140 in the active position. The locking bodies 29 in the interior of the housing 13, 15 are each pushed aside by the actuating bolt 27 of the advanced plug contact so that they cover the adjacent sliding slots 25. This not only offers protection against advancing two plug contacts at the same time, but also makes it more difficult to reach into the interior of the housing 13, 15 and to a current-carrying part with a needle or another thin and conductive object.

Figures 12 to 15 illustrate a function of the security body. Two holding rods 83 of the safety body 81 and a part of the lower part of the lower part 44 with the opener 45 are shown. The safety body has a rear wall 87, from which the holding rods 83 protrude vertically. The rear wall lies parallel to the inside of the wall with the socket 21 in the recess in the cover 15 and has openings (not shown) through which a plug inserted into the socket in the cover 15 extends into the plug sockets 73, 75. The security body 81 is resiliently displaceable relative to the socket by pressing the pusher 65 parallel to the rear wall 87. A function of the safety body, not shown, is that it can only be moved as long as no plug is inserted in the socket. By moving the Security body 81, the openings in the rear wall 87 are shifted relative to the insertion holes 49 of the socket and the insertion holes 49 are at least partially covered, so that a plug can only be inserted into the travel plug when the security body is pressed into its starting position by the spring 85.

The second function of the safety body is shown, namely securing a plug contact in the active control. In FIG. 12, the plug contact 144 with the carrier part 44 is in contact with the rear wall 87 of the safety body 81, that is to say in the passive position in the housing 13, 15 of the travel plug. In this position, the carrier part 44 is seated in a rear end position 90. In FIG. 13, the plug contact 144 is advanced a distance in the direction of the active position. During the displacement carried out, sliding surfaces 89 slide on the carrier part 44 via guide surfaces 91 directed obliquely to the displacement direction on the holding rods 83. Since the plug contact 144 is guided on a guide rod 79 on the main part 13, the safety body is pushed aside against the spring force of the spring 85. This shift can prevent a plug from being inserted into the travel plug as described above.

As shown in FIG. 14, this displacement of the safety body 82 is limited. The inclined guide surface 91 merges into a holding surface 93 extending in the direction of displacement. Only after the plug contact 144 has been displaced into the active position (FIG. 15) can the safety body 81 return to its starting control. This is possible, thanks to which an end control 95, which is set back relative to the holding surface 93, is formed on the holding rod. In the active position, the carrier part 44 of the plug contact 144 is seated in the end control 95. The recess in the end position allows the safety body 81 to be moved back into its basic position by the spring 85. A recess is formed through the recess of the end control, against which the carrier part 44 abuts and is thus secured against being pushed back. Together, the guide surface 91, the holding surface 93 and the end control 95 form a guide side for guiding the carrier element 44 on the holding rod 83.

The EU, AU and US plug contacts interact with the safety body 81 in an analogous manner. 16 shows the four plug contacts 138, 140, 142, 144 with the contact pins 37, 39, 41, 43, the opener 45 and the carrier parts 38, 40, 42, 44. Each carrier part has an actuating pin 27a, b, c, d and at least one Sliding surface 89. The carrier parts 40 and 44 of the US plug contact 140 and the UK plug contact 144 have two sliding surfaces 89. The sliding surfaces 89 each cooperate with the guide side of a holding rod 83 on the safety body 81. There are four holding rods 81, two of which each with both the UK and the US carrier 144 and. 140 interact.

FIGS. 17 to 20 show the controls of the three identical locking bodies 29 in the four different cases, in which a different plug contact is in the active position or at least not in the passive control. In Figure 17, the EU plug contact 138 is in the active position. In the direction of displacement of the locking bodies 29, these are arranged side by side. They are all moved together by the actuating bolt 27a towards the US plug contact. A locking body 29 extends from the edge of a sliding slot 25 to the corresponding edge of the adjacent sliding slot 25. As a result, the bottom locking body 29 blocks the sliding guard 25b and pushes the middle locking body 29 together with the top locking body 29. These block the sliding slots 27c and 27d.

In FIG. 18, the AU plug contact 142 is in the active control. The lowermost locking body 29 therefore covers the sliding protector 27a, the other two locking bodies are in the same position as in FIG. 17. They are held in this position by the actuating bolt 27b. Correspondingly, the UK plug contact 144 is in the active position in FIG. 19 and the UK plug contact 140 in FIG. 20. The locking bodies are each pushed out of the area of the sliding slot for the actuating pin concerned by the actuating bolts and, due to their dimensions and displaceability, cover the neighboring sliding slots , FIG. 16 also shows how the connecting conductors 69, 70, 71 are pressed against the contact pins 37, 39, 41, 43 in the active position of the plug contacts 138, 140, 142, 144. Directly next to the contact pins 37, 39, 41, 43, a groove 97 is formed in the carrier parts 38, 40, 42, 44, the bottom 99 of which connects to the contact pin. A pressure surface 101 rises from the base 99, running away from the contact pin. The groove 97 is therefore narrower at its base 99 than at its opening side. When the plug contact is advanced into its active control, the connecting conductors 70 and 71 are pressed against the contact surface 101 of the groove wall against the contact pin Contact pin guided. This is the case with the US, UK and AU plug contacts. In the case of the EU plug contact 138, the contact pins 37 are soldered together from the back to the tip. The connecting conductors 69 and 71 are also held in contactors in the euro plug-in body 35. These slots have a protective edge which runs at a flat angle towards the EU contact pin 37. This serves as a contact surface for pressing the connecting conductor onto the contact pin 37.

Various additives can be placed on the travel plug. In Figure 21, a multiple socket 103 is inserted into the recess of the socket. This multiple socket 103 has a connector surface visible in FIG. 22, from which two connection pins 107 protrude. These connection pins can be inserted into the holes 49 in the socket of the multiple plug and are then in contact with the plug sockets 73, 75. The multiple socket 103 has, on its socket side visible in FIG. 21, a perforated hole which allows a UK, US or AU plug to be inserted. It is possible to tap the movement of the guide pin 59 and to take over the safety function of the safety body 81 in the interior of the multiple socket 103 by moving a disc in the multiple socket with the movement and thus at least partially covering the socket holes. In the multiple socket, a closure for the socket holes that can only be actuated with the opener of a UK plug can also be provided. The multiple socket can be pivoted on the multiple plug.

The provision of additives such as this multiple socket 103 or the Schuko collar 105 shown in FIG. conflicting requirements met. The multiple socket 103 makes it possible to insert plugs with contact pins protruding from a relatively large area. This can e.g. for current transformers with the US plug standard of the FaU. The Schuko collar, on the other hand, guarantees the lateral overlap of the inserted Schuko plug prescribed by the German standard.

With a corresponding design of the multiple socket 103, the Schuko collar 105 can also be arranged either in the recess or on the part of the additional adapter protruding into the recess. When the multiple socket is attached, the Schuko collar then lies between the cover 15 and the multiple socket 103. Another addition is not shown, namely a current transformer for plugging into the socket of the multiple plug. This is advantageously adapted to the shape of the multiple plug and uses the space in the recess in the cover 15.

The multiple plug according to FIGS. 24 to 34 is a preferred further development of the first exemplary embodiment described above. The components are essentially the same, but some beneficial changes have been introduced.

24 shows two changes, namely a supplementary rib 201, which supplements the plug side 31 to form a closed round shape, so that the distances between the edge of the plug side 31 and the holes 137, 139, 141, 143 for the plug contacts are the same on both sides with respect to an axis of symmetry of the hole pattern. Furthermore, a recess 203 is formed in the recess 21 of the socket, into which the tip of the opener of a British standard plug inserted into the multiple socket 103 protrudes. This allows the insertion depth provided in the multiple socket to be minimized. In FIG. 25, the plug contacts 138, 140, 142, 144 are shown as they are stacked in the second exemplary embodiment. The UK 144 and EU plug contacts 138 are arranged next to one another, the carrier part 44 of the UK plug contact 144 is c-shaped and encompasses both other plug contacts, the US plug contact 140 and the AU plug contact 142. There is a space between them in which both the overload protection and the plug-in sockets 73, 75 of the socket are arranged.

The plug side 31 of the second exemplary embodiment is shown in FIGS. 26 and 27. It is evident that, in contrast to the first exemplary embodiment, the US contact pins 39 have moved further away from the edge. In this exemplary embodiment, the US plug contact 139 is arranged between the opener 45 and the contact pins 43 of the UK plug contact 144. In addition, the closed and symmetrical rounding of the edge of the plug side supplemented with the supplementary rib is shown. Further arrangement possibilities of the plug contacts are shown in FIG. 28, in which two variants are shown with interchanged AU and US plug contacts. Figure 29 shows the interaction of the various plug contacts. Each plug contact is guided directly or indirectly with a guide rod 79. This sits in a recess 78 in the carrier part of the plug contact or in the plug-in body 35 Recess 78 is a round hole corresponding to the guide rod 79. In addition, the plug contacts are brought together. 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 Kontaktsti 43 of the UK plug contact 144.

Furthermore, 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. 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.

In Figure 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. In the fifth exemplary embodiment according to FIGS. 35 to 42, the overload protection device 67 is connected in such a way that all plug contacts are protected. For this purpose, 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. In FIG. 42, 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 guidance of the locking bodies 29 is also improved in this exemplary embodiment. These are now on the outside of the housing wall, on the inside of an inner one

Kisses 117 led. This backdrop 117 is formed both on the cover 15 and on the Grundteü 13. An intermediate space directed in the direction of displacement of the locking bodies 29 which, together with a rib on the locking body 29, prevents the locking body from being displaced in a direction other than transverse to the sliding direction of the plug contacts (see FIG. 42).

It is further improved that the insertion body 35 is guided in a dovetail 135 in the basic part 13. In addition, 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.

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. Thanks to the insertion area at the terminals 175, 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. However, this is only the case with a plug contact in the active control (Fig. 41). In the case of the plug contact in the passive control (FIG. 40), connecting conductors 171, 172 and the contacts 177 are always separated. From the exploded view of the multiple socket 103 according to FIG. 38 it can be seen that 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. To achieve this, 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.

In Figure 42, 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. In addition to the described function of the voltage converter for the mains current devices, 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. In a simplification, the current transformer 193 has no plug-in sockets for the multiple socket 103, but only a direct current low-voltage connection 195. In another variant, 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.
