EP2297824B1 - Three-pole adapter set with a plug part and a socket part which may be plugged in the plug part - Google Patents

Description

The invention relates to a Zwischensteckset with a male part and one with three-pin plug contacts comprising a three-pin multiple power plug, which is equipped with pins of different power plug standards and a power outlet, and a plug for plugging into the socket.

A two-pole multiple power plug with push-out pins is from the WO 02/063722 known. This has in a housing two contact pins of a Euro plug contact with a push-out Euro plug-in body, a US plug contact, an AU plug contact and a UK plug contact with NC. This known power plug is provided with a socket into which a socket part with a multiple socket is inserted. The socket part has plug-in sockets for the two pins of a Euro plug, a US plug, an AU plug and three plug-in sockets for the pins and the opener of a UK plug. The socket part is equipped with special pins that are plugged into any standard socket, but only in the socket of the multiple power plug.

The bipartite nature of the kit allows the kit to be e.g. is supplemented with a voltage converter or other accessory, which voltage converter can be plugged into the socket of the multiple power plug and largely takes place within the recess of the socket, and is possibly equipped with a socket for the socket part.

Since the recess of the socket is too small to ensure a proper coverage of a Schukosteckers, this document proposes to make in the socket of the multiple power plug a Schukokragen used, which prescribed by the German standard coverage of a plugged into this socket Schukosteckers guaranteed. Since a Schukostecker must not be plugged into a two-pin socket, and therefore equipped with two-pin sockets to thick pins, this suggestion is not effective.

A disadvantage of the described subject matter is that the set can only make a transition from two-pole sockets to two-pole plugs.

From the German Patent No. 1 98 45 962 C1 is a three-pin adapter known. This has star-shaped plug contacts of different standards with three pins, and in the center of the star a Schukosteckdose. By turning a contact part in turn one plug contact is activated after the other, in each case only a single plug contact can be activated. A further development of this adapter is from the EP-A 1257 018 known. In this, the socket itself is rotatable to activate the plug contact of a particular standard. The commercially available version of this development has, in contrast to the version shown in the aforementioned protection, no hybrid Schuko plugs, but a plug exclusively French standard, which is not plugged into a Schuko socket German standard.

A disadvantage of these connectors is that they are only suitable for plugging Schuko plugs and two-pronged Euro plugs. Plugs for example, a US standard, an AU standard, a UK standard, a CH standard or an IT standard are not pluggable.

From the GB-A 2 366 087 is an adapter known, which is formed on an end face so that at this a variety of different face plates with plug contacts of different standard can be arranged. The back of the adapter is designed to accommodate a variety of different doses. So it can be combined different standards of plug contacts with different standards of cans. This can be assembled from a set of parts desired for the specific situation adapter plug. One embodiment shows such an adapter plug with a Schuko plug and a multiple socket for the standards of UK, US, AU, IT and other territories. A disadvantage of this adapter is that the front panel can be removed from the adapter and can be plugged without protection into a socket, whereupon live parts are bare and accessible. Presumably for this reason, this plug is not available as a kit, but only as a single adapter, the front panel is not replaceable. A disadvantage of the commercially available adapter plug, however, is that he now with the hybrid Schukostecker only in Schuko sockets German and sockets French standard is plugged.

It is therefore an object of the invention to provide a standard-compliant adapter plug, which mediates between most three-pin sockets, incl. The Schuko box, and most three-pin plugs, including the Schukostecker. This adapter should also have a small size.

• dass die dreipoligen Steckerkontakte des Steckerteils einer oder mehrer, unterschiedlicher Steckernormen entsprechen können, jedoch keinen Schuko-Stecker beinhalten,
• dass am Dosen-Teil unterschiedliche Steckernormen ausgebildet oder vorhanden sind - jedoch keine Schuko-Steckdose, und
  dass das Dosen-Teil mit dem Stecker-Teil mittels einer am Stecker-Teil ausgebildeten Schuko-Steckdose und einem am Dosen-Teil ausgebildeten Schuko-Stecker verbindbar ist. Schuko-Stecker und Schuko-Steckdose können dabei sowohl die deutsche als auch die französische Schuko-Norm beinhalten. Beim erfindungsgemässen Zwischensteckerset ist somit lediglich ein einziger Stecker vorhanden, der mit Schukosteckdosen oder Steckdosen französischer Norm kompatibel ist, und der als hybrider Schukostecker am Dosenteil ausgebildet ist.

The object is achieved by the subject matter of claim 1. This arrangement has the great advantage that such a Zwischensteckerset can be very compact, since both the Schuko-socket and the Schuko-plug are present only once on the Zwischensteckerset. This has the advantage that the plug contacts of the plug part do not have to have a Schuko plug, since the Schuko plug is already present in a separate socket part. If a Schuko plug is required, so only the can part is used. The can-part can - as can be seen from the figures - be designed as a very compact essay, since the bulky Schuko plug inside has plenty of room for receiving the plug contacts various other standards. In other words, the compact design of the intermediate plug set is achieved by

• that the three-pin plug contacts of the plug part can correspond to one or more, different connector standards, but do not include a Schuko plug,
• that at the socket part different connector standards are formed or present - but no Schuko socket, and
  in that the socket part can be connected to the plug part by means of a Schuko socket formed on the plug part and a Schuko plug formed on the socket part. Schuko plug and Schuko socket can include both the German and the French Schuko standard. The inventive Zwischensteckerset thus only a single plug is available, which is compatible with Schukosteckdosen or sockets French standard, and is designed as a hybrid Schukostecker on the socket part.

The inventive Zwischensteckerset has according to the prior art WO 02/063722 together that it is formed in two parts, and thus a Zwischensteckerset is formed from a male part with a socket and a suitable for this outlet plug with multiple socket. He has with the state of the art according to the DE 198 45 962 C1 common that the multiple plug is equipped with three-pin plug contacts and has a Schuko socket. He has according to the state of the art GB 2 366 087 common that the multiple socket has a hybrid Schukostecker.

However, beyond the teachings of this prior art, the invention teaches that a kit is to be formed from such a (multi) plug that does not have a Schuko plug and plug of French standard, and such a multiple socket with a hybrid Schuko plug. This set allows, in contrast to the cited prior art, to produce this adapter with a small size, because the plug part no Schuko plug is formed. For compatibility with Schuko sockets German and sockets of French standard, the Schuko plug of the can-part hybrid is formed. This ensures that neither a Schukostecker on the plug part nor a Schuko box must be formed on the can part, and with the help of this set nevertheless a variety of power plugs, including Schuko plugs, in a variety of doses, including Schuko doses, can be inserted. The Schuko and the Schuko plugs are also, despite their size and their eye-catching appearance, in the assembled state of the set components very space-saving and invisible arranged.

In the intermediate plug set is advantageously at least one precaution taken so that the hybrid Schukostecker can be inserted only in one position in the Schukosteckdose. This allows a correct polarization of the sockets and plug contacts can be achieved with arranged in the triangle pins.

Although a star-shaped arrangement of the different connectors is possible, so that the pins protrude approximately radially from the connector housing, it is preferred that the plug contacts of different standards relative to the housing of the connector part are slidably mounted. Conveniently, all pins are mounted parallel to each other displaceable. They are pushed into a passive position into the housing and into an active position out of the housing. This has the known effect that the plug part has a small size, because the plug contacts can be arranged nested thanks to this displaceability. The shiftability allows each of the pins of a Push plug contact a standard, while the pins of the other plug contacts are within the housing.

Advantageously, a CH plug contact is provided with a CH plug-in body, which is CH insertable into the housing and out of this pushed out, and the pins of the CH plug contact along a sliding path in the CH plug-in body in a passive position and off the CH plug-in body are also pushed into an active position. The CH plug contact has a particularly long sliding path because of the sliding path for the male body and the sliding path for the pins. This is longer than the other plugs. He would be just as long for a sliding Schukostecker. However, such is not provided according to the invention. Rather, a Schukostecker is formed on the socket part, which Schukostecker in a Schukosteckdose in the plug part can be inserted. This Schuko socket requires a relatively large depth, which extends in the same direction as the displacement of the CH plug contact.

Advantageously, therefore, the sliding path of the CH plug contact extends to next to the Schukosteckdose. This overlap of the sliding path of the CH plug contact and the insertion depth of the Schuko socket is the reason for the surprisingly small dimension of the plug set in the direction of displacement.

Another contribution to the shortness of the plug set in the direction of the displacement paths provides the preferred arrangement of all sockets of the multiple socket within the Schuko-Einsteckkörpers. Thanks to the size of the plug-in body of the Schuko plug contact, it is possible to accommodate the plug sockets for the pins of connectors of different standards.

The Schukodose can, apart from the peripheral ground contacts according to German standard, be formed with a ground pin French standard. The FR ground pin is particularly advantageous for the internal structure of the male part, as shown below. The Schuko box can be designed with or without FR ground pin. It is only a short, not protruding pin or a long, protruding pin in the plug part to use to produce these two for Germany and France preferably different deliverable sets.

In the case of three-pole plugs, the right polarization must be ensured in certain countries. With the socket of French standard, the polarization is given. The Schukostecker German standard, however, is not defined in terms of its polarization. Without appropriate measures, therefore, in a Schuko socket German standard all present in the socket part plug-in sockets are not defined in terms of their polarization, although all plug contacts (all except for IT and Schuko) are defined with respect to polarization. Thus, the polarization between plug contacts of the plug part and plug-in sockets of the socket part can not be rotated even with the intermediate plug sets with Schukodose German standard, an extension on the male part and a projection receiving recess is formed on the socket part, so that the socket part only in one position in the plug part is inserted. However, this can not prevent the Schukosteckkontakt the can part is inverted with respect to the polarization upside down in a Schukodose. Devices with a schuko plug must not be sensitive to the polarity. In the case of the standards with clear polarization, however, the plug can not be plugged in with polarization.

The prerequisite for the consistently correct polarization is that the polarization defined plug contacts, all of which have a triangle-pin arrangement with the ground pin on a plane of symmetry, are connected accordingly properly. For a simple contact guidance in the interior of the housing is of advantage that in each case the pins for the phase are arranged on the same side of this plane of symmetry. Therefore, if a UK plug contact, a US plug contact and an AU plug contact with a common plane of symmetry provided by the earth pins, the earth pin at the AU plug contact and the UK plug contact each on the same side, while the US plug contact compared to these arranged on the other side of its pins for phase and neutral.

If there is an FR ground pin in the Schuko box of the male part, then the polarization is maintained when it is in the common plane of symmetry and the two phase and neutral pins are on the same side as the ground pin of the US plug contact with respect to its pins for phase and neutral.

Overall, it is ensured that any existing plug standard is formed on the plug part and the socket part, that the plug-in sockets in the socket part in Regarding the orientation of phase, neutral and earth are arranged the same as the corresponding pins of the plug contacts of this standard on the plug side. The FR ground pin may also be present only within the housing, and absent outside the housing. Advantageously, the part within the housing namely forms a plain bearing. This allows a sliding contact between the earth pin of a sliding male contact and the sliding bearing, which is formed by the earth pin. The slide bearing can also be formed independently of the ground pin of the FR socket. It is advantageous, however, formed on an extension of the ground pin of the FR box, which extends through the housing. This design of the FR ground pin serves to stabilize and simultaneously ground. an extendable earth pin of a plug contact of another standard.

A socket part according to the preamble of claim 15 is for example from the DE 200 14 987 U1 known. The socket part according to claim 15 has the advantage that it is inexpensive to produce and allows to receive three-pin plug equal to several countries standards. According to the invention the socket part has at least four sockets of the country standards CH, IT, UK, US and AU. In combination with an adapter plug, which has a plug of any country standard (except a Schuko plug) and a Schuko socket, the socket part can provide the sockets of the economically most important countries in the world.

According to the invention, the ground contacts are arranged in a common plane and the phase pins and neutral pins are arranged symmetrically with respect thereto. This has the advantage that the can part can be constructed with a minimum number of different parts. According to the invention, a common insertion opening in the can plate is provided for the ground pins of the CH, IT, US and AU standard. This has the advantage that the can part can be particularly compact.

According to another aspect of the invention, the socket part can at least any two sockets of the country standards Israel (IL), India (IN), or Denmark (DK). Preferably, all three aforementioned country standards are realized in a single can part. Because of that Sockets are housed in the Schukosteckergehäuse, the can part is relatively small and compact.

To stabilize the FR ground pin, this slide bearing pin is fixed both on the front side in the housing of the plug part and on the back side in the bottom of the Schuko socket.

The intermediate plug set 11 in FIG. 1 has three-pole plug contacts in a plug part 13 and three-pole plug sockets in a socket part 15. The plug sockets together form a multiple socket 16 (FIG. Fig. 3 ). The pins of the plug contacts and clips of the sockets are arranged symmetrically to a plane of symmetry 10 through the ground pins and earth clips. The plug contacts 20 (CH / IT), 30 (AU), 40 (UK), 50 (US) are between a passive position, in which the plug contacts 20 are inserted into the housing of the plug part 13, and an active position, in which the plug contacts 20 protrude from the housing, sliding. The shift from the passive to the active position and back done with actuation buttons 27, 37, 47, 57, in FIG. 3 are visible. The plug contacts 20,30,40,50 are arranged in conformity with the standard polarized. The polarization is not unique for the CH / IT plug contact 20 with the ground pin in the position for Italy can not be clearly defined. In FIG. 1 are on the left side of the phase pins 21,31,41,51, on the right side of the figure, the neutral pins 22, 32, 42, 52 and between them on the plane of symmetry, the earth pins 23, 33, 43, 53rd arranged.

The CH / IT plug-in contact 20 has a push-out insert body 25. In this plug-in body 25, the pins 21,22,23 are slidably mounted. They are therefore pushed out into the active position and inserted into the illustrated passive position, wherein in the active position and the male body 25 is extended by the prescribed length of the standard from the housing. In the active position, the pins of the CH / IT plug contact displaceable in the plug-in body 25 are further pushed out of the plug body by their pin length. In the active position, the CH / IT ground pin 23 can move into an IT-compliant position (in line with the Pins 21 and 22) or a CH-compliant position (triangle arrangement) are pushed. This displacement of the ground pin 23 in the active position is perpendicular to the direction of displacement of the plug contact. The displacement of the ground pin 23 is done by hand.

According to the invention, in this plug-in connector set 11 in the plug part 13, a Schuko socket 17 (in FIG FIG. 3 visible), in which the can part 15 can be inserted. The can body 15 has a hybrid Schukostecker 19. Hybrid means that the Schukostecker 19 can be inserted in both Schukodosen the French and the German standard. The hybrid Schukostecker 19 is conventionally formed. Then to the Plug-in body 18 of the Schukosteckers 19 is a collar 61 is formed, which can rest on the back 63 of the male part 13.

The Schuko box 17 is formed with a ground contact 71 according to the German standard and with a ground pin 73 according to the French standard. However, especially for use in Germany, where non-hybrid Schuko plugs are commonly present, the ground pin 73 may be missing. The Schukostecker 19 of the can part 15 fits in both cases in the Schukodose 17th

On the Schuko plug opposite the can side of the socket part 15 are female sockets 29, 39, 49, and 59 for the plug contacts 20,30,40,50 of the male part 13 corresponding plug standards available. These sockets together form a multiple socket 16. The socket side has a plurality of insertion holes, which correspond to the plug contacts of different country standards. Behind the holes metal terminals are arranged, in which the plug contacts can be inserted. The clamp for the CH earth pin is the same as for the US earth pin. The insertion holes in the housing for the earth pins of the Italian, Swiss, US and Australian standards are connected. The plug-in holes for the phase and neutral pins of UK and AU plugs are also connected.

So that the polarization of the clearly polarized plug contacts 20,30,40,50 and sockets 29,39,49,59 match, they are aligned the same. For UK and AU plugs or sockets, if the ground pads are over the other two pins or jacks, the CH and US plugs and sockets have these ground pads under the other two pins or jacks.

If the Schukostecker 19 on the socket part 15 and the Schuko socket 17 on the plug part 13 are both hybrid, the polar connection between plug contacts and socket is safe. However, if the Schuko socket 17 is equipped on the plug part 13 without ground pin 73, a Schuko plug can be plugged into two positions. To prevent this at Schukostecker 19 on the socket part 15, an extension 65 is formed on the back 63 of the plug part 13. This extension 65 cooperates with a recess 67 on the collar 61 of the can part 15 when the can part 15 is placed in the correct orientation. If the socket part 15 is twisted by 180 degrees, then it can not be plugged into the Schuko socket. As a result, the can part 15 is plugged into the plug part 13 only in a position in which the contours of the plug part and the can part fit together become. However, Schukostecker of electrical equipment can be plugged in any orientation in the Schuko box 17 on the plug part 15.

In FIG. 5 is the Zwischensteckerset 11 without housing of the connector part 13 shown. As a result, the sliding parts of the plug contacts 20,30,40,50 are visible. The can part 15 is inserted into the plug part 13. It can be seen that the Schuko box 17, which includes the male body 18 of the Schukosteckers 19, and the sliding area for the CH / IT connector 20 are arranged side by side. The side of the can 17, the rear region of the male body 25 and the slider 26 of the pins 21, 22, 23 of this plug-in contact 20 is arranged.

When advancing the slider 26 by means of the actuating lever 27 ( Fig. 3 ) This pushes against a stop edge of the male body 25 and pushes this into the active position. Upon retraction, the slider 26 abuts a rear catch nose (not visible in the figures) and pulls the male body into the passive position.

In the active position minipins 28 are plugged into three contact strips 81,82,83. These mini-pins 28 are in conductive contact with a respective pin 21, 22, 23 of the plug-in contact 20. The contact strip 81 is in contact with terminals 69 for the pins of the Schukosteckers 19th

The other plug contacts 30,40 and 50 need a smaller sliding path and are arranged in the sliding direction in front of Schukodose 17. The terminals 69 for contact with the pins of the Schukosteckers 19 are arranged between the pins of these plug contacts. These other plug contacts 30,40,50 stuck in the active position with minipins 38,48,58 in the contact strips 81, 82, 83rd

An exception is the ground pin 33 of the AU plug contact 30. This slides with a pickup 35 via a pin 75. This pin 75 is in conductive contact with the ground contact strip 83 and, if present, is the extension of the FR ground pin 73rd

In FIG. 6 the AU plug contact 30 is shown in the active position. The plug contacts 40 and 50 are removed from the illustration so that it is clearer. In FIG. 7 is the AU plug contact in the passive position. The pickup 35 is located on the pin 75 at the very least.

In the FIGS. 6 and 7 Shields 85 are also recognizable. These shields 85 are slidably mounted in a guide and are pushed by the operating lever 27,37,47 and 57 each to the side when these operating lever 27,37,47,57 are advanced into the active position. They then lie against each other without a gap. As a result, they prevent a second plug contact can be advanced into the active position.

In the FIG. 5 Furthermore, a locking part 87 is shown. This has an actuating head 89 and can be moved by pressing the operating knob 89 against the spring force of a spring 91 ( FIG. 6 ). The spring 91 is secured in the plug part 13 on the housing inner wall. By displacement against the spring force reach arms 93 of the locking member 87 out of engagement with the sliders 26, 36, 46, 56 of the plug contacts. By moving the locking member 87 by the spring force reach his arms 93 into engagement with the sliders 26,36,46,56 of the plug contacts and lock them both in the active position and in the passive position.

As can be deduced from the thickness of the collar 61, the terminals of the plug-in sockets in the socket part are all disposed within the male body 18 of the Schukosteckers 19.

The intermediate plug set is composed of a plug part 13 and a socket part 15. The plug part 13 is equipped with three-pole plug contacts (20,30,40,50) different standards and a three-pin Schukosteckdose 17. The can part 15 is equipped with a three-pole Schukostecker 19 and a three-pole multiple socket 16. The Zwischensteckerset 11 includes only a single Schukostecker 19, namely formed on the can part 15. By an earth pin (73) and / or an extension (65) on the plug part, which cooperates with a recess (67) on the can part, a provision is made, which prevents the can part 15 are inserted into the Schukosteckdose 17 in two different positions can.

The inventive adapter plug set 11 may have instead of a multiple plug a plug part 14 a - c with a three-pin plug contact a first standard and a Schuko box 17. As in the 8 to 11 For example, the plug may be such a Swiss 14b, Italian 14a, or African 14c, or any other country standard except a Schuko plug. A Schuko plug will be on the plug part not needed, since this is already formed on the can-part 15. The adapter plug set with a plug part 13 with a three-pole plug contact of a first standard and a schuko box 17 and a socket part 15 is particularly advantageous for hotels that receive travelers from different countries. These hotels may, if necessary, provide the travelers with an adapter plug having a national standard plug 14a-14c and a schuko-box 17, and a socket member 15 having a schuko plug 19 and a plurality of three-pole sockets, including that of the national standard of the passenger having. This adapter set allows hoteliers to provide travelers with the correct electrical outlet for their electrical equipment.

The can part 15 according to the invention is characterized in that it has in each case a plurality of at least three, preferably at least four different three-pole sockets of different country standards. An inventive adapter plug set can therefore plug side different connector parts combined with a schuko box 17 and the can side different can parts 15 with three-pin sockets different national standards each combined with a Schuko plug 19 have.

• eine Dosenplatte 111, welche auf das Steckergehäuse 101 aufsetzbar ist und in welcher die Einstecköffnungen 29,39,49,59 für die unterschiedlichen Stecker der verschiedenen Ländernormen ausgebildet sind,
• wenigstens drei Kontaktteile105,107,109, welche die Klemmkontakte für die Aufnahme der einzelnen Pins bilden und in das Gehäuse 101 einsetzbar sind, und
• einem Niederhalter 113 aus Kunststoff, welcher in das Steckergehäuse 101 einsetzbar ist.

According to FIG. 12 the can parts according to the invention each have a Schuko plug housing 101 with Schuko plug contacts 103 and in Schuko plug housing 101 arranged a plurality of terminals 105,107 for receiving the plug pins of plug the different country standards. The can parts 15 may comprise a few parts, namely

• the Schuko plug housing 101, which has on the front side the Phasepin 103 a and the neutral pin 103 b,
• a can plate 111 which can be placed on the plug housing 101 and in which the insertion openings 29, 39, 49, 59 are designed for the different plugs of the various country standards,
• at least three contact parts 105, 107, 109, which form the terminal contacts for receiving the individual pins and can be inserted into the housing 101, and
• a hold-down 113 made of plastic, which is insertable into the plug housing 101.

In addition, a child safety device 115 may be provided between the can plate 111 and the hold-down 113. The child safety device 115 is displaceable on the hold-down device 113 in a specific displacement direction. The child safety device 115 is biased by means of a spring 117 which is supported on the housing wall in an advanced end position in which the child safety locks the insertion holes 29,39,49,59 for the phase and Nulleiterpins at least partially. This prevents children from coming into contact with the live lead terminals during play. If the plug pins of a plug are inserted into the insertion holes, the child safety device is pushed back against the force of the spring 117. For this purpose, inclined sliding surfaces 120 are provided in the plate, which come to rest in the rest position behind the insertion.
