Description of the Invention: [Technical Field] The present invention relates to a device for feeding electric power to one of the electrodes of an electric lamp, having at least one current-carrying pin and at least one current-carrying foil interconnected at a joint sheet. The invention further relates to an electric lamp having such a device for feeding power to an electrode. [Prior Art] With the simultaneous development of both discharge lamps and halogen lamps, their power is gradually increased, and there is a fixed or even reduced bulb size, or a reduced luminous cooling effect, and thus will make its components Placed under extreme thermal stress. The power supply components of such lamps are typically constructed of, for example, molybdenum which is oxidized at temperatures in excess of about 350 °C. Since, for example, a system with a current carrying pin and a current carrying foil is embedded in the quartz glass of the bulb, there is no room for bulky molybdenum oxide expansion. This will even cause the lamp to fail early due to cracks in the handle, or even a light burst. A lamp is known from the German Patent No. DE 699 27 574 T2, in which a protective coating is formed on the outer conductor and on the carrier foil to which it is attached. The protective layer is formed as a thin layer of only about 4 micrometers to 6 micrometers, and is composed of, for example, chromium. Based on the capillary formed between the inner wall of the bulb neck on the one hand and the current-carrying foil on the other hand and the current-carrying pin member extending outward, the protective coating must extend to cover the entire length of the current-carrying pin and must also cover One of the current-carrying foils is exposed. The coating of the coating is relatively complex and time consuming. In addition, the cost of the coating is relatively high' and the coating procedure will also be detrimental to the health of the materials used to form the coating. In addition to this, the coating must be applied to the current-carrying foil and the current-carrying pin before the dissolution process. 201007813 However, based on the inner wall of the bulb neck, a capillary configuration between the current-carrying foil and the outside of the current-carrying pin, and the coating applied thereto, only during the melting process, thus relative It is relatively difficult, and often unpredictable, whether a sufficient antioxidant protection can be produced after the melting process by the coating. Since the coating material will also melt during the melting, it is not possible to further expect a sufficient oxidative protection to meet the pre-defined and desired requirements. Further, a heat lamp is known from the Japanese Patent Publication No. 2001210279 A, in which a plurality of rod-type power supply wires extend into a combustion chamber, which is surrounded by a sealing material at the end side of the bulb, and/or at the end of the bulb. The side opening is encapsulated with the material. The sealing material is formed with a specific radius which is in a specific relationship with the diameter of the power supply pin so that a gap can be formed between the sealing material and the bulb when necessary. SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for feeding power to an electrode of an electric lamp and an electric lamp having the same, wherein the electric lamp, and/or the anti-oxidation protection current in the power supply device Parts will be improved and lower expenditures can be achieved. Φ This problem can be solved by a device having a power supply to an electrode as characterized by the first aspect of the patent application, and an electric lamp having the features of the ninth aspect of the patent application. An apparatus for feeding power to an electrode of an electric lamp in accordance with the present invention includes at least one current carrying pin and at least one current carrying foil interconnected at a joint. The cross-sectional area of the at least one current-carrying pin is less than or equal to the cross-sectional area of the at least one current-carrying foil, at least in the range of the joint between the current-carrying pin and the current-carrying foil. By using such a device architecture and/or in an electric lamp, such as a capillary configuration formed at the power supply for the 201007813 device during a discharge lamp melting or extrusion process, it can be at least substantially reduced, thereby The crack in the handle of the bulb at this position can also be reduced to a considerable extent. First, the size of the capillaries is based on the difference in expansion coefficient between a bulb composed of a quartz material and a power supply unit preferably composed of molybdenum, and based on the current-carrying pin and The diameter of the current-carrying foil is given. By virtue of the device architecture of the present invention, the diameter of the components, the current-carrying foil, and the current-carrying pin will now be reduced and/or adjusted to accommodate such that the carrier still has the desired current carrying The capacity 'and the capillary member can be minimized, or a minimized power supply assembly can oxidize the top surface, thereby also reducing at least the chance of cracking of the handle. The above may minimize the diameter of the current-carrying pin only by making the cross-sectional area of the current-carrying pin less than or equal to the cross-sectional area of the at least one current-carrying foil; however, the interaction with the current-carrying foil is considered. The role needs to be ensured at any time to ensure the required current carrying capacity and other factors. Preferably, at least one of the current carrying pin cross-sectional areas is less than or equal to 0.75 times the enthalpy of the cross-sectional area of the at least one current-carrying foil, at least in the range of the joint. Particularly preferably, it can be designed to 'at least in the range of the joint' the at least Φ one of the current carrying pin cross-sectional areas being less than or equal to 0.5 times the enthalpy of the cross-sectional area of the at least one current-carrying foil. A further reduction in the diameter of the further current-carrying pin can again achieve a positive effect to prevent capillary action when the current-carrying device current-carrying member is embedded in an electric bulb. It is recognized that a current-carrying pin is attached to a substantially rod-shaped member' which can be connected to a substantially sheet-shaped or plate-shaped member in the form of a current-carrying foil. The current-carrying pin and the current-carrying foil thus have a significantly different geometric architecture. It is also possible to design such that the cross-section of the current-carrying pin and the current-carrying foil are interconnected and formed outside the joint. 201007813 can similarly be designed such that the device has at least two current carrying pins and includes, for example, only one current carrying foil. In the case of such an arrangement, it is preferably designed such that the sum of the cross-sectional areas of the at least two current-carrying pins is less than or equal to the cross-sectional area of the at least one current-carrying foil. Even when a plurality of current-carrying pins are formed, they can be designed to be reduced in cross-sectional area such that the sum of the intercepts of all of the current-carrying pins is smaller than the cross-sectional area of the single current-carrying chip. It is also possible to at least substantially reduce the capillary action during the insertion of the bulb process via this specially developed power supply, and still ensure complete current carrying capacity. It is also possible for the device to have at least two current-carrying foils, and at least in the range of the joint points, the cross-sectional area of the current-carrying pins is less than or equal to the sum of the cross-sectional areas of the current-carrying pins of the device. Therefore, it is also possible to provide an architecture in which the device comprises a plurality of current carrying foils but only a single current carrying pin. It is also possible to design such that the cross-sectional area of the current-carrying pin is always smaller than the sum of the cross-sectional areas of the current-carrying foils. Of course, in the structure with several current-carrying pins or several current-carrying foils, it can be understood that the term "joint point" refers to the sum of the joint points, thereby showing, for example, a number of current-carrying pin systems and one load. The flow foil is connected at several points, or a plurality of current-carrying foils are connected to a current-carrying pin at a plurality of points. Here, the connection between the at least one current carrying pin and the at least one current carrying foil is described, preferably a soldering. It may also be designed to 'make the device have at least two current-carrying pins and at least two current-carrying foils' and at least in the range of the joint points, the sum of the cross-sectional areas of the current-carrying pins is less than or equal to the current-carrying box pieces. The sum of the cross-sectional areas. The at least one current carrying pin of the power supply unit and the at least one current carrying foil are preferably made of a molybdenum containing material, in particular entirely of molybdenum. Preferably, the current-carrying foil and/or the current-carrying pin are made up of at least 400 c, in particular up to 500. (:, specifically up to 6.01, especially up to 10.0. (: ' 201007813 is still one of the materials that remain oxidatively stable. It can be designed to coat the current-carrying foil with an anti-oxidation protective coating. And/or the current carrier, which may have, for example, chromium, and/or platinum, and/or aluminum, and/or pins. Further, the device is designed to be used in the current-carrying pin and the current-carrying foil A more mechanically stable state is achieved between the joints, which is particularly more stable than the known standard connection of such power supply devices, and this will in particular form a relatively large diameter. An electric lamp 'includes a basis The invention provides a device for feeding power to the Φ-electrode of the lamp, or a preferred arrangement thereof, whereby the lamp can prevent, and/or at least reduce, when the lamp is embedded in the power supply device. Capillary formed in the melting and/or extrusion process. In addition, the current carrying capacity can be maintained. Preferably, the electric lamp comprises a bulb having a combustion chamber into which at least one electrode will extend, and further comprising a bulb neck connected to the combustion chamber The power supply device connected to at least the electrode is disposed therein and extends outward from the bulb neck. Preferably, the at least one current carrying pin of the power supply device and the at least Φ-carrier foil The joint between the two is disposed outside the fitting region, wherein the power supply device is deformed in the neck portion of the bulb and embedded in the bulb neck in the fitting region. Specifically, the fitting The zone is understood in particular to be a pressing zone and/or a dissolution zone, such that the components of the power supply device can be airtightly embedded in one of the bulb necks by extrusion. The joint is preferably arranged in In addition to this mating zone, a significant positive effect on avoiding capillary formation, and in particular oxidation of the corresponding component of the power supply device, can be achieved again, thereby again reducing the chance of cracking of the handle. 201007813 In particular, the joint is disposed in a cavity formed in the bulb neck away from the combustion chamber, the cavity being at least partially filled with a sealing material for extending into the bulb neck The oxidation protection against the oxidation of the power supply device assembly provides that the sealing material is a conductive glass solder. Preferably, the electric lamp comprises an oxidized stabilizing lamp holder and/or the lamp holder An oxidative stabilizing material is coupled to a bulb neck. The structure of the device feeding power to an electrode is a minority of current carrying pins and/or at least one of the plurality of current carrying foils Arbitrarily arranged in parallel. Therefore, the system first has one of the current-carrying pins, one of the current-carrying foils, and a pair of front and rear configurators. More specifically, the two current-carrying pin systems are arranged in several Close to each other, one of them is connected to the same end, so that it can be made or two joints. Similarly, for the specific embodiment of the power supply single current carrying pin and several current-carrying foils, the current-carrying foil The sheets are configured to be spaced apart from each other and connected to the flat pins. For example, a conventional standard discharge lamp having a diameter of about i mm (mm) and/or a current-carrying pin has been shown to be severely reduced to, for example, 0.5 mm after about 50 hours of testing. At this time, the time will be up to 500 hours, and in some cases, the service life is very high. In addition, the profile of the current-carrying pin is particularly reduced, wherein the cavity is at the end. Preferably, the power supply is protected. In this way, it can be positively affected again. Specially made at least one coating. In particular, it can be understood that the design of the current-carrying system is not known to the prior art, and that the current-carrying foil is formed as a joint, and the supply device is still included. In this line, and the shank crack in the 500 ° C furnace with the current supply device. When the conversion factor is 10, i can reach 750 hours. The assembly will allow the 201007813 power supply unit to save tensile elastic components that are typically soldered to conventionally thicker current-carrying pins, such as wires and similar. In particular, in the case of a metal base, it is preferred to use an oxidative stabilizing material or an oxidative stabilizing coating. The lamp holder can be designed to be constructed of stainless steel. For a coating of a lamp holder, it is again conceivable to have a material such as chromium, and/or platinum, and/or gold, and/or aluminum, and/or zirconium. The cavity may be designed to be formed at a tip end of a bulb, particularly a bulb neck, and at least partially filled with a sealing material to protect the power supply device from longitudinal viewing along the power supply device The portion that extends into the neck of the bulb is protected from oxidation. Additionally, an additional layer may be formed at least regionally on the sealing material to resist oxidation of the power supply extension in the neck of the bulb. One of the materials is also placed during the manufacture of the lamp and is preferably used as a sealing material. Therefore, the cost reduction can be equally allowed. An electrode is understood to mean, for example, an anode of a discharge lamp and a cathode. Similarly, the term electrode is also understood to mean a bulb, in particular a filament of a halogen bulb. In particular, the power supply device is embedded in the bulb neck via a material that melts and/or squeezes the neck of the bulb at a suitable point. Then, it is particularly preferable that the cavity formed on the end side of the bulb neck can be filled with the sealing material after the embedding process. Therefore, it is no longer necessary to complete a coating on the power supply device before the melting process as in the prior art, and then in the subsequent melting process, it is necessary to ensure that the melted coating is distributed at the desired position. . In a preferred embodiment of the invention, a substantially clear and precise introduction of the sealing material can be implemented when the extrusion process has nearly ended and the geometry of the cavity is known and it is no longer changed.

This will avoid large gaps. Therefore, it is possible to avoid the harmfulness which will be caused to a considerable extent and even in the prior art, when viewed in the radial direction, the cavity system. Preferably, the cavity is formed only on one end of the bulb neck gf of the combustion chamber. The at least partially filled cavity extends a relatively short length along the longitudinal direction of the bulb neck and the longitudinal direction of the supply device, and is more economical to improve oxidation protection. Moreover, the base position can also be implemented relatively simply and inexpensively, preferably by the length of the cavity, and thus the end of the inner extrusion range away from the combustion chamber. The sealing material can thus be specially configured to be correspondingly sized for the shape of the plunger chamber. Particularly preferably, it can be placed in the cavity in an inert atmosphere. An inert gas such as argon may be provided, which is particularly effective in discharging the existing oxygen and, in the right, preventing oxygen from entering. Thereby, the oxidation protection is further, in particular, can therefore be incorporated when the sealing material is introduced. The sealing material is preferably a high temperature stable adhesive which allows the adhesive to maintain temperature stability up to 450 ° C, particularly up to 800 ° C. When? Viewing to the ground, intervening cavity gaps, where high oxygen passes through the wind in the prior art. Therefore, the sealing material is completely filled away from the extrusion range and therefore along the power source will therefore be extended to ensure that the cost is lower than the introduction of the particular cavity sealing material. The end will pass through this type and the sealing material is introduced based on the void. The introduction of the sealing material via this side is further improved. Stop harmful oxygen inducers. It can be designed up to 600 ° C, and the special sealing material is an inorganic -10- 201007813 adhesive is preferred. For example, Cerastil® can be used as an adhesive. It can also be designed such that the sealing material is a metal foam material. Preferably, it can be designed such that the sealing material is foamable and has aluminum particles. By heating the sealing material, the material will bulge into a metal foam and completely fill the cavity. Preferably, the antioxidant intrusion protective layer is formed in the sealing material away from the range of the bulb combustion chamber. Preferably, however, an additional anti-oxidation intrusion protection of the outer side can be formed. The attachment location of the protective layer can be completed simply and with less expense and still ensure improved antioxidant intrusion protection. The anti-oxidation protective layer and the sealing material are preferably constructed from a variety of different materials. In particular, the layer is formed in the sealing material from a range in which the cavity protrudes. Even with this architecture, it is easy to measure the expansion of the surface of the layer and the thickness of the layer, which is changed and optimized. Preferably, the anti-oxidation intrusion protective layer for the power supply device is formed directly on the sealing material. As such, no other materials and/or other layers will be disposed between the layer and the sealing material. However, in principle, it is also possible to design the layer so that the layer and the sealing material are not directly attached to each other, and thus an intermediate layer will be formed. Preferably, the layer for resisting oxygen intrusion comprises at least a proportion of polyamidene. Similarly, the layer can be designed to include at least a proportion of one of the ceramic fiber materials. For example, "Tyranno Coat" from UBE Industries can be used here. Preferably, the layer is formed from a material that remains thermally stable up to 500 °C. The bulb preferably has at least two bulb necks that will oppose the combustion chamber relative to -11-201007813. The electric lamp can be constructed as a single-ended discharge lamp. It can also be designed such that the electric lamp is constructed as a double-ended lamp. The electric lamp is preferably constructed as a discharge lamp. It can also be embodied as a halogen bulb.

The lamp I has a bulb 1 comprising a spherical central portion with a bulb neck 2 and a bulb neck 3 joined to the opposite side. The bulb 1 is integrally formed, and a discharge space 4 as a combustion chamber is formed in the center portion. In the present embodiment, one of the rod-shaped first electrodes 5 is formed in the discharge space 4. The first electrode 5 is electrically and mechanically connected to a power supply device 6, 7. In this embodiment, the electrode 5 is made of tungsten or a tungsten-containing material. The power supply unit comprises a current-carrying foil 6 which is composed of molybdenum or a molybdenum-containing material and which, when simultaneously gas-tightly melted in the bulb neck 2, will form a sealing foil. Furthermore, the power supply unit comprises a current-carrying pin 7' which is also formed in a rod type and consists, for example, of molybdenum or a molybdenum-containing material. Correspondingly, a second electrode 8 is provided on the opposite side, which is also formed as a rod and extends in the discharge space 4.

In the drawings, the current-carrying pin 10 and the current-carrying foil 9 are shown as an illustrative example. In this embodiment, the lamp I is designed as a double end. A single-ended discharge lamp is available. Similarly, an electric lamp I can also be used to concentrate the bulb. The current-carrying foil 6 is welded to a portion of the neck portion 2 which extends beyond the bulb portion 2 at a joint point 13. At the end 21 of the bulb neck 2 away from the square, a cavity 11 is formed. Since the basic structure of the bulb neck 2 is designed as a tubular member, the cavity is a cavity 11 having a substantially circular cross section. The longitudinal axis of the bulb neck 2 corresponds to the longitudinal direction of the power supply means 6, 7 and thus also to the longitudinal axis A of the electrode 5 pin 7. The current-carrying pin 7 is disposed axially with the cavity 11, whereby the longitudinal axis of the cavity 11 will correspond to the bulb neck:. Figure 1 shows the lamp I in a processing state, which is still attached to the base. This means that the power supply units 6, 7 will dissolve in the portion and the material of the bulb neck 2 will be squeezed into a fitting extrusion zone 22. Therefore, the current-carrying foil 6 will be air-tightly bubbled into the neck portion 2. The squeezing range 22 itself extends only to cover a portion of the length of the bulb neck and terminates substantially below the cavity 、 and at the end of the joint 13 . It is also possible to provide a joint 13 formed outside the pressing range 22, which joint may also be arranged in the cavity. In the present embodiment, the cavity 11 is completely filled with a power supply device for the supply of 9 and 1 turns. However, it also becomes a halogen. The current-carrying pin 7 t is electrically spaced. And the current-carrying axis is substantially the same as: the longitudinal axis A is the end side of the bulb neck region, and/or is disposed in the lamp: portion 2 as a whole. Special sealing material -13- .201007813 12. The sealing material 12 itself is constructed to protect the portion of the power supply device 6, 7 extending from the bulb neck 2 from oxidation. The sealing material 12 can have a temperature resistance of more than 800 00. (An inorganic adhesive. However, a metal foam material can also be provided as the sealing material 12. In the specific implementation shown in the drawings, the cavity 11 itself extends only into the bulb neck 2, and the joint 1 One of the three phase spacing points is such that the sealing material 12 will not contact the joint 13 and thus the current-carrying foil 6. The longitudinal distance is indicated by 1. Further, the current-carrying pin 7 has a diameter dl , which is substantially smaller than the diameter d2 of the cavity 11. The thickness of the sealing material 12 given by the distance 'from the outside of the current-carrying pin 7 to the inner wall of the cavity 1 1 of the bulb neck 2 will be greater than, in particular substantially greater than, the current-carrying pin 7 radius (dl)/2). As can be seen from Figure 1, the sealing material 12 only surrounds the periphery of the current carrying pin 7. The sealing material 12 is refilled into the cavity 11 after the fitting process, and thus the bulb neck 2 is melted and squeezed in the extrusion range 22. The radial extent of the cavity 11 will thus be substantially greater than in the melting process, and in the subsequent cooling process, 'formed in the range of the joint 13 between the material of the bulb neck 2 and the current-carrying foil 6, and the range of extrusion. 22, a capillary between the bulb neck material and the current carrying pin 7. The range of the bulb neck 3 is not in a cross-sectional view, but is viewed from the outside to a side view of the lamp I. The architecture of the lamp I in the bulb neck 3 is similar to that in the bulb neck 2 range. As a commentary, a cavity 14' is drawn which has a radius r corresponding to one of the axes A. Here, a cavity 14 is also formed in the bulb neck 3 away from one end 31 of the discharge space 4. It also extends only to a range of extrusion 32. The cavity 1 1 extends in the direction A of the longitudinal axis A from the edge -14, .201007813 of the rear end 21 of the bulb neck 2 to the beginning of the extrusion range 22. The cavity 14 is sized in the bulb neck 3 in a similar manner. Therefore, the electrode 5 will be inserted into the tubular bulb neck 2 with the power supply means 6, 7 when the lamp I is manufactured. Thereafter, the squeezing range 22 is generated by heating the bulb neck 2 and melting the quartz glass material at appropriate points. Further, an extrusion process is carried out at a suitable point of the bulb neck 2 to achieve gas-melt melting of the carrier foil 6. Next, the bulb neck 2 is cooled and may be expanded by the different materials to form a capillary tube, not shown, at the joint 13 and around the current-carrying pin A7. The sealing material 12 is introduced into the cavity 11 until after cooling. A lighter can be made in the range of the bulb neck 3 correspondingly. The introduction of such a sealing material 12 can be carried out, for example, by an argon atmosphere or the like under an inert gas atmosphere. The oxygen removal achieved with the sealing material 12 is sufficient to allow for at least 500 hours at a temperature of at least 500 ° C at the power supply unit 6'7. This is still true in the range of the bulb neck 3. An inorganic adhesive such as Cerastil® can be used as the sealing material β 1 2, so that the adhesive can also be used for the attachment of the susceptor or the base of the lamp I. When the lamp I is embodied as a halogen bulb, it may preferably be designed such that the attachment and/or insertion of the sealing material 12 in the cavity 11 is carried out in synchronism with or at least partially in synchronism with a production process in which the base is fixed. . The result of the description based on the design of the lamp I in the range of the bulb neck 2, for the design and procedure in the bulb neck 3, and/or when there is a corresponding lamp I in the second bulb neck The second bulb neck can be similarly established. As can be seen from the diagram of Fig. 1, the ends of the cavities 11 and 14 facing the discharge space 4 -15 - 201007813 are formed in a circular shape. The sealing material 12 can also be constructed as a plunger-type seal by surrounding and dimensioning of the cavities 11 and 14. As can be seen from the diagram of the figure, the sealing material 12 extends beyond the trailing edge and/or the edge of the trailing end 21. As indicated by Figure 1 of the drawings, a further coating 16 is formed on the sealing material 12 for protecting the power supply units 6, 7, 9 and 10 from oxygen intrusion. The coating 16 is formed directly on one of the top faces 15 of the sealing material 12 wherein the top surface 15 appears to be away from the combustion chamber 4 and face one of the top sides of the surrounding ring. In a particular embodiment, the sealing material 12 is introduced into the cavity bore such that it projects outwardly beyond the edge of the trailing end 21 at a particular curvature. The coating 16 is applied to the edge of the rear end 21 in addition to being applied directly to the epitaxial top surface 15. The sealing material 12 at the top surface 15 is exposed so that it can be completely covered by the coating 16. The coating 16 is applied to the top surface 15 in particular after the sealing material 12 has been completely formed in the cavity 11. The coating 16 can be made of a polyimide or ceramic fiber material and, in particular, can remain thermally stable up to 500 °C. With the additional coating 16, it is again possible to reduce oxygen permeability and extend the service time limit to possible occurrence of shank cracks. The duration of protection at elevated temperatures around 500 °C will be improved by about 15% to 20% by additional coating 16. It ensures that it can be applied to all discharge lamps and halogen bulbs covered by it. In the particular embodiment illustrated in Figure 1, the lamp 1 includes power supply means 6, 7 and/or 9, 10. Each of them has a current carrying pin and a current carrying foil. Of course, it is also possible to design that an electric lamp has at least two current carrying pins and/or at least two current carrying foils. This will result in a number of joints 13. Also, in the specific embodiment of the present invention, the sum of the cross-sectional areas of the current-carrying pins may be designed, at least in the range of the joint 13 or, if necessary, the plurality of joints 13. It may be less than or equal to the cross-sectional area of the single current-carrying foil. The edge may also be designed such that at least one of the current carrying pins may have a cross-sectional area that is less than or equal to the sum of the cross-sectional areas of at least two current-carrying foils in at least one or more of the joint points 13. The edge may also be designed such that, in the range of the joint 13, the sum of the cross-sectional areas of the current-carrying pins may be less than or equal to the sum of the cross-sectional areas of the current-carrying foils. Further, in Fig. 1, a specific embodiment is shown in which the joint 13 is formed outside the cavity 11, and is specifically disposed in a fitting region and/or the extrusion m range 22 such that the joint 13 Nor will it melt. It can also be designed such that the joint 13 is arranged outside the pressing range 22 and is situated in particular in the cavity 11. In this particular embodiment, it can be provided that the current-carrying foil 6 is extended so as to extend into the cavity 11 and, at this point, a joint 13 can be formed with the current-carrying pin 7 which is shortened if necessary. . This also applies to the opposite side components 9 and 10 in the range of the bulb neck 3. In Fig. 2, a cross-sectional view taken along section line B B is shown, wherein the section plane will therefore be orthogonal to the plane of the drawing. In Fig. 2, the current-carrying foil 6 and the current-carrying pin 7 at the position of the joint 13 are shown in a schematic view and enlarged view of φ. The current-carrying pin 7 has a cross section C having a substantially circular cross section, and the cross section D of the current-carrying foil 6 is rectangular. When the dimensions of the sections C and D are adjusted, it is intended that the cross-section D of the current-carrying pin 7 in the range of at least the joint 13 is less than or equal to the section D of the current-carrying foil 6. Thus, the size of the radius (d 1/2) of the current-carrying pin 7 can be adjusted correspondingly to form a corresponding thin current-carrying pin 7. Particularly advantageously, if at least in the range of the joint j 3 'the cross section C of the at least one current-carrying pin 7 is less than or equal to 0.75 times the cross-sectional area 値 of the at least one load -17- « 201007813 flow foil 6 , in particular Section C will be less than or equal to 0.5 times the area 截面 of section D. A further embodiment is shown in Fig. 3, which differs from the specific embodiment of Fig. 2 in that the current-carrying pins 7 are not disposed on either side of the current-carrying foil 6, but are only abutted and welded to one side.
