Description

TECHNICAL FIELD

[0001] The invention relates to a high-power plug connector system according to the type of the independent claim 1.

[0002] Such a high-power plug connector system is required for the transmission and / or distribution of high voltages and high currents. Particular attention is paid here to the suitability in the area of the floor underbody of rail vehicles, in particular the connection of rail cars and rail carriages to one another. BACKGROUND

[0003] The solutions known from the prior art enable the transmission and / or distribution of high currents and / or voltages between vehicles or between vehicles with attached modules. However, these solutions generally provide for an unfavorable and partially non-releasable fixing of the respective contact elements.

[0004] Furthermore, a particular disadvantage of the prior art is the lack of ease of maintenance, the rigid design of the system and also generally a high weight and considerable space requirement. Due to the high power requirements of modern passenger rail traffic, the previous solutions in the prior art are outdated and inefficient. In particular in the case of contact elements that are subjected to large stresses, for example in the area of rail traffic, due to the increasing requirements, for example due to the increase in high currents of more than 500 A up to several thousand amperes and voltages of more than 500 V up to several thousand volts, the demand for repair and maintenance is also increasing.

[0005] The German Patent and Trademark Office searched the following prior art in the priority application of the present application: DE 41 35 391 C1. SUMMARY

[0006] It is an object of the present invention to provide a versatile high-power plug connector for the transmission and / or distribution of high currents and / or voltages.

[0007] The object is achieved by the subject matter of the independent claim.

[0008] Advantageous design features of the invention are specified in the dependent claims and the following description.

[0009] According to an embodiment of the present application, a high-power plug-in connector system is proposed, which has a cable connection housing for connecting at least two high-power electrical plug-in connectors for transmitting and / or distributing high currents and / or high voltages. The cable connection housing is designed for accommodating at least two insulators and at least one electrically conductive track in an interior space. In this case, the insulators are designed for respectively accommodating at least one high-power contact, and the electrically conductive track is designed for producing an electrically conductive connection between the at least two high-power contacts. The insulators also at least partially respectively protrude from the interior space into a connection region through a housing bore. The connection region is designed to accommodate the high-power plug-in connectors.

[0010] The cable connection housing can thus at least serve as a coupler for the at least two high-power plug-in connectors. Ideally, the cable connection housing according to the present application is designed as a distributor. In particular, the cable connection housing is designed as a Y-distributor. The cable connection housing is advantageously designed as a T-distributor. Furthermore, the cable connection housing is advantageously designed as an H-distributor. The cable connection housing can also be designed as an X-distributor.

[0011] The term "high-power plug-in connector" refers to a plug-in connector which is intended to be connected to the cable connection housing. In particular, the high-power plug-in connector according to the present application is designed as a single-pole plug-in connector. Such a high-power plug-in connector is also referred to as a single-pole. The high-power plug-in connector is primarily designed for transmitting high current strengths and / or high voltages onto the cable connection housing.

[0012] "High current strength" means a current strength of more than 100 amperes. In particular, a current strength of more than 500 amperes is meant. In particular, a current strength of more than 800 amperes is meant. A current strength of more than or equal to 1,000 amperes is also conceivable.

[0013] The term "high voltage" means a voltage of more than 1 kilovolt. In particular, a voltage of more than 10 kV is meant. In particular, a voltage of more than 15 kV is meant. A current strength of more than or equal to 25 kilovolts is also conceivable.

[0014] "Housing bore" means an opening in the cable connection housing. The housing bore leads from the interior space of the cable connection housing into the surrounding outer region. The outer region around the cable connection housing is designed as a connection region at least around the housing bore.

[0015] The "connection region" is understood to be the outer region of the aforementioned cable connection housing. Here, the connection region is shaped according to the application such that the high-power plug connector is brought onto the insulation located in the housing opening and is connected thereto in an electrically conductive manner. By connecting the high-power plug connector to the connection region, a media-tight closure of the interior space is provided at the appropriate point according to the application. For this purpose, the housing of the high-power plug connector is shaped such that it engages into the substantially uniformly designed connection region. Both the high-power plug connector and / or the connection region of the cable connection housing are provided with a seal in order to improve the closure.

[0016] In another embodiment, the cable connection housing is designed to have a substantially concavely shaped housing upper side.

[0017] In this context, the housing upper side is understood in particular to be a housing wall which is connected to a support structure, for example of a vehicle or of an attached transport element, which is opposite the housing upper side. In this case, the embodiment discloses a housing upper side whose concave shape extends from the left side to the right side. The maximum deflection of the concave shape is thus along a longitudinal axis of the cable connection housing which is substantially arranged in the middle. The maximum deflection of the concave shape of the housing upper side is oriented along a transverse axis of the cable connection housing which is normally arranged in the middle. Ideally, the maximum deflection of the concave shape of the housing upper side is substantially arranged in a center point region of the cable connection housing. The point defined as the intersection of the longitudinal axis and the transverse axis can be selected as the center point. The concave housing upper side has the advantage, first of all, that foreign media, in particular water, dirt and dust, can simply flow off or be washed off the housing upper side.

[0018] One embodiment provides that the cable connection housing has at least two recesses which enable the cable connection housing to be connected to a support structure.

[0019] The recess means, for example, a depression in which a bolt, pin, screw, threaded pin or similar connection element can be accommodated. For example, such a recess is designed as a groove along the outer side of the cable connection housing. Here, the groove can be shaped such that it has an outwardly directed opening through which the connection element can pass completely or at least partially.

[0020] Alternatively, the recess is designed as a through-hole through which a bolt, pin, screw, threaded pin or similar connection element can pass. The recess is designed, for example, as a through-hole. Alternatively, the recess is designed as a blind hole. The recess is optionally designed as a slot.

[0021] The supporting structure is, for example, the floor of a rail vehicle. Another example of a supporting structure is a steel bracket designed to connect to a cable connection housing. Furthermore, the supporting structure can be made of another load-bearing material. Ideally, the supporting structure is made of an electrically conductive material. A supporting structure with a favorable thermal conductivity is particularly advantageous. Here, "favorable thermal conductivity" refers to high thermal conductivity.

[0022] In an advantageous embodiment, the recesses are each arranged on at least one projection on the outside of the cable connection housing.

[0023] Here, a protrusion is, for example, a metal plate attached to the cable connection housing. In particular, the protrusion projects beyond the basic shape of the cable connection housing. It is particularly preferred that the cable connection housing has a protrusion formed on its housing top. Ideally, the cable housing top is generally rectangular. The housing top has at least one protrusion on opposite sides, each having at least one recess for securing the cable connection housing.

[0024] The cable connection housing with polygonal basic shape and substantially rectangular housing upper side is particularly preferred. Here, the housing upper side projects beyond at least one side of the polygonal basic shape of the cable connection housing, wherein recess is arranged in the outstanding projection formed in this way.

[0025] An ingenious embodiment provides that the interior space has at least a first insulating shell and a second insulating shell, wherein the first insulating shell and the second insulating shell are arranged one on top of the other along at least one side wall.

[0026] An insulating housing is a molded component formed from a non-conductive material, particularly plastic. The present invention is based on a substantially rectangular bottom surface of the insulating housing. Alternatively, the bottom surface of the insulating housing can be polygonal. Alternatively, the bottom surface can be circular. Thus, the insulating housing has a hollow cylindrical shape.

[0027] At least approximately vertically shaped side walls are arranged on the circumferential sides of the bottom surface. According to the present invention, the insulating shells essentially overlap on at least one side wall, advantageously on at least two side walls. Ideally, the bottom surfaces of the first and second insulating shells are approximately the same and / or their bottom surfaces differ only by the thickness of the respective insulating shells. This means, for example, that the first insulating shell has a larger bottom surface than the second insulating shell, or vice versa. The difference in the bottom surfaces of the first and second insulating shells thus enables the first insulating shell to at least partially accommodate the second insulating shell. According to the present invention, the first insulating shell is placed into the interior space of the cable connection housing. The second insulating shell is inserted into the first insulating shell in a mirror-image manner around the axis, so that the space between the first and second insulating shells is essentially closed. Cleverly, this size and / or arrangement enables the insulating shells to be nested in the side walls, thereby positively increasing the required clearance and creepage distances.

[0028] A clever embodiment provides that the cable connection housing accommodates at least one closure cap for the media-tight closure of the connection region. In this case, a closure cap refers to a cap or cover which is shaped to cover at least one connection region of the cable connection housing. A closure cap also refers to a cap or cover which can be inserted into a connection region, wherein at least one housing opening is closed. Ideally, the closure cap is shaped such that it is inserted into the connection region and secured therein. According to the application, the securing of the closure cap enables at least a water-tight and / or dust-tight seal. Cleverly, the closure cap and / or the connection region is provided with a sealing element in order to improve the sealing effect.

[0029] A further improved embodiment provides that the cable connection housing has a housing cover for the media-tight closure of the interior space. The housing cover is cleverly arranged on the housing underside. According to the application, the housing cover seals the interior space of the cable connection housing in connection with the cable connection housing, which at least prevents the ingress of water and / or dust and dirt. By using a housing cover, a maintenance access can be provided. According to the application, the housing cover is provided with a connection element which requires a special tool to detach the housing cover from the cable connection housing. The use of a locking mechanism is also conceivable. In this way, a basic protection against tampering is achieved. In order to improve the protection against tampering, the housing cover can be arranged in the housing upper side. According to the application, the housing cover is therefore designed to have an at least partially recessed shape. The housing cover and / or the corresponding part of the cable connection housing is cleverly provided with a sealing element in order to improve the sealing effect against foreign media.

[0030] A practical embodiment provides that the housing cover has a recess for accommodating a closure cap. Here, in order to save space and simplify the accessibility of the closure cap, it makes sense to arrange the housing cover on the housing underside. Here, the closure cap is detachably secured to the housing cover by means of a connection element. This embodiment is particularly clever when the cable connection housing is designed as a distributor. For example, if a high-power plug connector system is designed as a Y-distributor, the cable connection housing used can be used in a simple manner for multiple purposes. In one application, a high-power plug connector system designed as a Y-distributor is used as a distributor by allowing at least three high-power plug connectors to be connected to the cable connection housing. In an alternative application, a high-power plug connector system designed as a Y-distributor is used as a connection system. For this purpose, two high-power plug connectors are connected to the cable connection housing and the third connection region of the cable connection housing is sealed with a closure cap.

[0031] One embodiment, which is particularly oriented towards safety, provides that the cable connection housing is provided with at least two essentially flat contact surfaces on at least the housing upper side. Cleverly, the protrusions of the housing upper side are shaped as flat contact surfaces. Ideally, these contact surfaces are also connected to flat surfaces and are fastened on these flat surfaces by means of connecting elements such as screws or similar connecting elements. With regard to safety, it is proposed that the contact surfaces and untreated surfaces are connected to one another. A connection to electrically conductive, corrosion-resistant substances is also conceivable. Thereby, a ground transmission can be achieved without an additional ground conductor. Tests have shown that three screw connections, for example designed as M8 threads or larger threads, are sufficient to achieve a ground transmission of 150 A. In addition, the contact surfaces can be used for redundant safety, for example to compensate for corroded screw connections. Ideally, the contact surfaces can be used for heat transfer. By means of this additional heat transfer, a particularly compact design can be created, since the cable connection housing has to allocate less installation space as a cooling surface.

[0032] With reference to the aforementioned embodiments, one embodiment provides that the contact surfaces at least reach the height of a plane formed by a straight line running essentially parallel to the cable connection housing and the highest point of the concave deflection of the housing upper side.

[0033] This means that the contact surfaces at least reach the same height as the at least one concave shaping at the maximum deflection of the at least one concave shaping pointing away from the cable connection housing. Preferably, the contact surfaces protrude beyond the maximum deflection of the concave-shaped housing upper side. Thereby, the cleaning of the high-power plug-in connector system, in particular of the cable connection housing in the assembled state, can be improved and simplified. In addition, this advantageous gap between the concave housing surface and the support structure accommodating the high-power plug-in connector system leads to an improved air circulation. This air circulation in turn leads to a positive cooling effect. By means of this cooling effect, a compact design can be created, since the cable connection housing needs to allocate less installation space as a cooling surface.

[0034] In a further improved embodiment, it is provided that the housing lower side is provided with at least one essentially flat contact surface. The shape of this contact surface serves for connecting a ground conductor. As is known, copper bars are often used as ground conductors. These ground conductors can be used as an additional safety measure for the shielded transmission. In addition, such a ground conductor can be used as an alternative to the flat contact surfaces on the housing upper side.

[0035] A further embodiment provides that the upper side of the housing is formed by an at least substantially rectangular basic shape. Furthermore, this embodiment provides that the lower side of the housing is formed by an at least substantially rectangular basic shape. Particularly preferably, the further improved embodiment provides that the lower side of the housing is formed by an at least substantially rectangular basic shape and a substantially trapezoidal basic shape arranged thereon. The resulting polygonal basic shape is particularly suitable for use as a high-power plug connector system for a distributor. In particular in the case of use as a Y-shaped distributor, the basic shape of the polygonal shape has advantages in terms of the volume of the cable connection housing.

[0036] The embodiment which is easy to maintain also provides here that the high-power plug connector system comprises at least one thermochromic element. Preferably, a thermochromic element in the form of a sticker is used. Alternatively, at least one thermochromic element in the form of a lacquer is used. Particularly preferably, the thermochromic element is applied to at least one component of the high-power plug connector system under a protective or sealing lacquer layer. In order to detect errors early and to improve maintenance, it is recommended here to use a thermochromic element with irreversible colour change. In this way, it can be identified directly during maintenance work whether a certain component of the high-power plug connector system has been overloaded. In a clever further development, the thermochromic element is assigned an electrical and / or electromagnetic signal transmitter. In this case, the signal transmitter is designed in particular as an RFID transponder. When using an RFID transponder, it is also particularly preferred to introduce an element therein for irreversibly changing the transmitted data. For example, a thermosensitive element can be included in the transponder. As an alternative, the RFID transponder is connected to a thermosensitive element. As soon as the thermosensitive element is activated and / or damaged, for example due to excessive temperatures, the signal from the RFID transponder changes, so that a fault can be detected.

[0037] The invention also relates to an electrical power transmission system consisting of at least two high-power plug connector systems according to the invention. The high-power plug connector systems are fixed to at least one segment of a transportation system consisting of a plurality of segments and accommodate at least one electrical conductor between them.

[0038] In this case, the electrical power transmission system is understood to mean the use of at least two high-power plug connector systems according to the invention. In particular, one segment of the transportation system is designed as a vehicle system consisting of at least two segments, for example an articulated bus, in particular as part of a trolleybus of the articulated bus. The segment is particularly preferably understood to mean a car of a rail vehicle and / or a vehicle combination.

[0039] A further embodiment of the electrical power transmission system proposes that at least a first high-power plug connector system is attached at a first end of a segment of the transportation system and at least a second high-power plug connector system is assigned in the approximately central region of the segment.

[0040] Furthermore, one embodiment of the power transmission system provides that at least the third high-power plug connector system attached at the second end of the segment of the transportation system.

[0041] Furthermore, one embodiment of the power transmission system provides that at least the first high-power plug connector system located at the first end of the segment of the transportation system is assigned a substantially structurally identical at least fourth high-power plug connector system to achieve a safety-related technical redundancy.

[0042] Furthermore, one embodiment of the power transmission system provides that at least the third high-power plug connector system located at the first end of the segment of the transportation system is assigned a substantially structurally identical at least fifth high-power plug connector system to achieve a safety-related technical redundancy. In other words, according to this power transmission system, at least the first high-power plug connector system and the fourth high-power plug connector system are located at the first end of the segment on a segment designed as a rail wagon. At least the third high-power plug connector system and the fifth high-power plug connector system are positioned at the second end of the segment opposite the first end. At least the second high-power plug connector system is connected to the segment in the area between the first end and the second end. In some cases, it makes sense to use at least the second high-power plug connector system as a simple line connector or even to omit it.

[0043] “Safety-related technical redundancy” means that a high-power plug connector system is designed to receive and respond to the power transmitted by another high-power plug connector system in use in the event of a malfunction. In other words, one high-power plug connector system can take over the task of another high-power plug connector system in use at least in the short term. This feature is particularly needed in rail transport, since a malfunction on the route can have far-reaching effects and must therefore be prevented as far as possible.

[0044] Another embodiment provides a power transmission system in which at least the second high-power plug connector system accommodates at least one line for operating at least one electrical consumer of the segment of the transportation system. In this way, for example, a temperature regulation system, for example a heater and / or an air conditioning system, can be operated in a passenger train / car. In the case of a goods transportation wagon, for example, at least one electric servo motor and / or a similar actuator can be provided.

[0045] In a particularly advantageous embodiment, at least one high-power plug connector system of the power transmission system is provided with at least one thermochromic element from at least one section which is visible from the outside, in particular at least one component of the high-power plug connector system. At least the operating temperature is optically visualized by means of the thermochromic element. In particular, thermochromic elements are used which change color irreversibly at least at elevated temperatures. In a clever further development, the thermochromic element is assigned an electrical and / or electromagnetic signal transmitter. In this case, the signal transmitter is designed in particular as an RFID transponder. When using an RFID transponder, it is also particularly preferred to introduce an element therein for irreversibly changing the transmission data. For example, a thermosensitive element can be included in the transponder. As an alternative, the RFID transponder is connected to a thermosensitive element. As soon as the thermosensitive element is activated and / or damaged, for example due to excessive temperatures, the signal from the RFID transponder changes, so that a malfunction can be detected.

[0055] Figure 1 A perspective view of a high power plug-in connector system 1 according to the application is shown from "above". In this case, the high power plug-in connector system 1 shown has a cable connection housing 2 and two high power plug-in connectors 3 fixed thereon. The high power plug-in connectors 3 are introduced into the connection region 9 of the cable connection housing 2 and are fixed there on the cable connection housing 2 by means of a threaded connection. The person skilled in the art can derive alternative options for fastening the high power plug-in connectors 3 on the cable connection housing 2. For example, the high power plug-in connectors 3 can be equipped with a latching mechanism, such as a push-pull mechanism. The high power plug-in connectors 3 can be equipped with a locking nut, which is screwed onto an outer thread, wherein the outer thread is provided on the connection region 9 of the cable connection housing 2. Furthermore, the high power plug-in connectors 3 can be provided with a threaded sleeve in order to be screwed into an inner thread arranged in the connection region 9. Furthermore, it is also possible to use fixing brackets, levers, wedges, clamping elements, for example clamps or conical clamping bushes, for example conical bushes. The housing upper side (Go) of the cable connection housing 2 extends concavely, wherein the housing upper side (Go) has the greatest deflection along the longitudinal axis of the cable connection housing 2. Along the base body of the cable connection housing 2, protrusions 11 can be seen. These protrusions 11 are provided with recesses 10. These recesses 10 are designed as through-holes or through-going holes. In the illustration of Figure 1 , these recesses 10 have been provided with connection elements, more precisely with screws. They are screwed into a support structure, for example the chassis or the floor of a rail car, or are connected with threaded elements. Unlike the majority of the housing upper side (Go), the protrusions 11 are not concave, but are designed at least in principle as flat contact surfaces 14. In order to achieve a particularly advantageous electrical grounding connection, these flat contact surfaces 14 are connected to an electrically conductive surface of the support member. In order to protect against dirt and weather, the contact is subsequently sealed, for example by painting. Furthermore, the contact surfaces 14 are designed to dissipate the heat generated by the cable connection housing 2. In the illustration of Figure 1 , the contact surfaces 14 of the protrusions 11 protrude beyond the greatest deflection (auslenkung) of the concavely designed housing upper side (Go). On the one hand, this achieves a dissipation of the generated heat by means of the air flow that can be achieved when driving. Furthermore, cleaning is simplified since dirt, dust and water can simply flow to the side or out of the cable connection housing 2.

[0056] Figure 2 A view of the high power plug-in connector system 1 according to the application from "below" is shown. The cable connection housing 2 is also connected in Figure 2 to two high power plug-in connectors 3. As in Figure 1 , the connection region 9 for the further high power plug-in connector 3 is in theFigure 2 The recess 10 in the protrusion 11 has been passed through by a connecting element, which is a screw as shown, for example, for fixing the cable connection housing 2 to a support structure. In addition, the connecting element is designed for establishing an electrical ground connection. The housing underside Gu has two contact surfaces 14. These contact surfaces 14 are designed in particular for connecting at least one ground conductor. A copper fabric band is usually used as a ground conductor. The housing underside Gu is provided with a housing cover 15. For assembly and / or maintenance purposes, the interior space 7 is accessible through the housing cover 15. The housing cover 15 is also shaped with a recess 16. This recess 16 is in turn shaped such that the closure cap 13 can be accommodated in the recess 16 at least to a small extent. Ideally, the closure cap 13 can be detachably connected to the housing cover 15 by a connecting element, for example a screw.

[0057] Figure 3 and 4 A view into the interior space 7 is possible. In the case of Figure 3 , the high-power plug-in connector system 1 is shown in horizontal cross-section, while in Figure 4 , the high-power plug-in connector system 1 is shown in vertical cross-section. Figure 3 A cable connection housing 2 is shown, which has a high-power plug-in connector 3 in a connection region 9 and a closure cap 13 in an adjacent connection region 9, while the connection region 9 is shown as unused. Three individually positioned insulators 4 are arranged in the interior space 7. In the case shown, they take on the shape of a (inverted) Y very roughly. The insulators 4 extend through the associated housing perforations 8 and thus establish a connection between the interior space 7 and the respective connection region 9. In addition, the insulators 4 each accommodate a high-power contact 5. The high-power contacts 5 are guided through the insulators 4 and through the housing perforations 8 into the respective connection region 9. For the establishment of an electrical connection, the high-power contacts 5 are fixed approximately in the middle of the interior space 7 with a rail 6. In the embodiment shown, the high-power contacts 5 are fastened to the rail 6 with screws. Figure 3 and 4 The illustration in

[0058] The power transmission system 17 consisting of the high-power plug-in connector system 1 according to the invention is shown in Figure 5A first high-power plug-in connector system 11 is shown at the first end El of a segment 18 of a transportation system. The transportation system is for example a passenger car. The first high-power plug-in connector system 11 is connected to a second high-power plug-in connector system 12 of the same construction. The second high-power plug-in connector system 12 is connected via electrical conductors to a third high-power plug-in connector 13. The first high-power plug-in connector system 11 is connected to a fourth high-power plug-in connector system to establish redundancy. This fourth high-power plug-in connector system 14 is directly electrically conductively connected to a fifth high-power plug-in connector system 15. Furthermore, the high-power plug-in connector systems 15 and 13 are in electrically conductive contact for reasons of redundancy. The high-power plug-in connector systems 11 and 14 are thus at the first end El of the segment 18. The high-power plug-in connector systems 13 and 15 are at the other end E2 of the segment 18. An electrical consumer 19 is located between the two ends El and E2 of the segment 18. This electrical consumer 19 can for example be a temperature regulation system, in particular an air conditioning system or an electrical heating system. The electrical consumer 19 is connected via electrical lines to the high-power plug-in connector system 12. The high-power plug-in connector systems 1 are here of the same construction and can be arbitrarily interchanged with one another. The high-power plug-in connector systems 11, 12 and 13 form here an electrical connection from the first end El of the segment 18 to the second end E2 of the segment 18. Here, the high-power plug-in connector system 12 serves not only as an electrical connection, but also as a branch for supplying the electrical consumer. The high-power plug-in connector systems 14 and 15 form another electrical connection from the first end El of the segment 18 to the second end E2 of the segment 18.

[0059] Even if different aspects or features of the application are shown in the drawings in a combined form, it is obvious to a person skilled in the art that the shown and discussed combinations are not the only possible ones. In particular, units or features of different embodiments can be combined with each other independently, if this makes sense.
