Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, and particularly to a conductive roller structure and its accessories. Background Art

[0002] The conductive roller structure and its accessories are usually used in generators. When the generator is working, the conductive roller rotates to drive the conductive ring to rotate, and the current flows into the carbon brush through the conductive roller and the conductive ring, so as to transfer the current to the static external circuit. The contact resistance between the conductive ring and the carbon brush is inversely proportional to the contact area and the contact force between the two. The greater the contact resistance, the more heat is generated.

[0003] In the prior art, the outer wall surface of the conductive ring is usually a smooth curved surface, and the contact area between the conductive ring and the carbon brush is often small, resulting in a large contact resistance. Patent CN219304130U discloses a high-life small carbon brush elastic conductive slip ring. Among them, the outer wall surface of the conductive slip ring is a smooth curved surface, and the end surface of the carbon brush in contact with the conductive slip ring is a flat surface, resulting in a large contact resistance between the two, which affects the current transmission effect.

[0004] In addition, during the relative rotation of the conductive ring and the carbon brush, the carbon brush will be worn to varying degrees, resulting in changes in the contact resistance between each carbon brush and the conductive ring, uneven current distribution, and thus affecting the overall working efficiency of the equipment. At the same time, the uneven contact resistance of each carbon brush leads to uneven heat generation of the contact resistance on each carbon brush, and local overheating may occur, increasing the potential safety hazard. Summary of the Invention

[0005] An object of the present invention is to reduce the contact resistance between the conductive ring and the first carbon block, thereby reducing the transmission loss of the current and improving the current transmission effect of the conductive roller structure and its accessories.

[0006] Another object of the present invention is to improve the uniformity of the contact resistance between each conductive ring and the first carbon block, avoid local overheating, and thus reduce the potential safety hazard.

[0010] Further, the two conductive rings at both ends of the conductive roller are fixed relative to the conductive roller, and the remaining plurality of conductive rings move along the axial direction of the conductive roller under the pressing of the first carbon blocks.

[0011] Further, a plurality of grooves are provided on the conductive roller, and a plurality of support components are provided in the plurality of grooves; each support component is connected to one conductive ring; the plurality of support components support the plurality of conductive rings to enable the plurality of conductive rings to rotate under the drive of the conductive roller.

[0012] Further, the support component includes: a support block disposed inside the conductive ring; two second hinge members symmetrically disposed on the support block; a second tension spring disposed between the two second hinge members, and its two ends are respectively connected to the two second hinge members; two second carbon blocks disposed in the groove and respectively hinged to the two second hinge members; a second conductive belt disposed between the support block and the conductive ring, and the two ends of the second conductive belt are respectively connected to the two second carbon blocks.

[0013] Further, the conductive roller structure and its accessories further include: a plurality of cleaning components disposed on the outer periphery of the plurality of conductive rings and corresponding to the plurality of conductive rings one by one, for removing the oil stains on the wedge-shaped surfaces of the plurality of conductive rings.

[0014] Further, the cleaning component includes: a clip piece clamped on the wedge-shaped surface of the conductive ring, for scraping the oil stains on the wedge-shaped surface of the conductive ring when the clip piece and the conductive ring rotate relatively; a support rod connected to the clip piece for supporting the clip piece.

[0019] Furthermore, for the conductive roller structure and its accessories of the present invention, by setting a pressing component, the pressing component is used to press the first carbon block, increasing the contact force between the first carbon block and the conductive ring, thereby reducing the contact resistance between the first carbon block and the conductive ring and ensuring the current transmission efficiency.

[0020] Furthermore, for the conductive roller structure and its accessories of the present invention, by fixing the conductive rings at both ends and enabling the remaining conductive rings to move axially along the conductive roller under the pressure of the first carbon block, the conductive rings can automatically adjust their corresponding positions according to the magnitude of the applied pressure. This makes the contact forces on each conductive ring reach a relatively balanced state, thereby reducing the non-uniformity of the contact forces between each conductive ring and each first carbon block. It avoids excessive contact resistance in a certain area leading to local overheating, reduces the risk of fire, and minimizes potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following refers to Figures 1 to 12 to describe a conductive roller structure and its accessories provided by the present invention.

[0041] This embodiment first provides a conductive roller structure and its accessories. The conductive roller structure and its accessories generally may include: a housing 100, a conductive roller 200, a plurality of conductive rings 300, and a plurality of first carbon blocks 400.

[0042] The conductive roller 200 is rotatably arranged in the housing 100. A plurality of conductive rings 300 are sleeved on the conductive roller 200 and are arranged at intervals along the axial direction of the conductive roller 200. Among them, a wedge-shaped surface 310 protruding outward is formed on the outer ring of each conductive ring 300. A plurality of first carbon blocks 400 are arranged on the outer periphery of the conductive roller 200, and the shape of the side wall surface of each first carbon block 400 is adapted to the wedge-shaped surface 310 of the adjacent conductive ring 300. At least one first carbon block 400 is arranged between every two adjacent conductive rings 300. The two side wall surfaces of each first carbon block 400 are respectively abutted against the wedge-shaped surfaces 310 of the two adjacent conductive rings 300.

[0043] In the solution of this embodiment, by setting the outer ring of the conductive ring 300 as the wedge-shaped surface 310 protruding outward and setting the shape of the side wall surface of the first carbon block 400 to be adapted to the wedge-shaped surface 310 of the adjacent conductive ring 300, the two side wall surfaces of the first carbon block 400 are respectively abutted against the wedge-shaped surfaces 310 of the two adjacent conductive rings 300 to form an inclined contact surface. The inclined setting of the contact surface between the conductive ring 300 and the first carbon block 400 increases the contact area between the conductive ring 300 and the first carbon block 400, thereby reducing the contact resistance, lowering the transmission loss of the current, and improving the current transmission effect of the conductive roller structure and its accessories.

[0044] In the solution of this embodiment, the first carbon block 400 is set to be in contact with the conductive ring 300, and the first carbon block 400 is used for conducting electricity. It not only has good electrical conductivity, but also has excellent lubricity and current collection performance, improving the overall working efficiency of the conductive roller structure and its accessories.

[0045] In some embodiments, the length of the first carbon block 400 (along the circumferential direction of the conductive ring 300) can be set to gradually shrink from the bottom surface close to the axis of the conductive ring 300 to the top surface, so that the end surface of the first carbon block 400 has a certain inclination angle. When the first carbon block 400 is in contact with the conductive ring 300 and rotates relatively, the end surface of the first carbon block 400 can scrape off the oil stain on the conductive ring 300 and discharge it along the end surface in the direction away from the conductive roller 200, avoiding the attachment of oil stain on the wedge-shaped surface 310 of the conductive ring 300 from affecting the conductive effect and ensuring the normal operation of the conductive roller structure and its accessories.

[0046] The conductive roller structure and its accessories generally may further include at least one mounting plate 110 and a plurality of pressing components 500.

[0047] At least one mounting plate 110 is provided on the housing 100. A plurality of pressing components 500 are arranged on at least one mounting plate 110 at intervals along the axial direction of the conductive roller 200. Each first carbon block 400 is connected to a pressing component 500 and moves radially along the conductive roller 200 under the drive of the pressing component 500.

[0048] In the solution of this embodiment, by providing the mounting plate 110 on the housing 100, and then providing the pressing component 500 on the mounting plate 110, the pressing component 500 is used to drive the first carbon block 400 to move radially along the conductive roller 200, so that the first carbon block 400 can be tightly attached to the conductive ring 300, thereby reducing the contact resistance between the first carbon block 400 and the conductive ring 300, and further reducing the energy loss of current transmission.

[0049] In some preferred embodiments, a plurality of mounting plates 110 can be installed on the housing 100, and the plurality of mounting plates 110 are evenly distributed around the conductive roller 200. A certain number of pressing components 500 are provided on each mounting plate 110. The plurality of pressing components 500 drive the plurality of first carbon blocks 400 to jointly press the conductive ring 300, which not only increases the contact force between the first carbon block 400 and the conductive ring 300, reduces the contact resistance between the first carbon block 400 and the conductive ring 300, but also ensures the coaxiality of the conductive ring 300 and the conductive roller 200, and improves the operating reliability of the conductive roller structure and its accessories.

[0050] In some embodiments, the end face of the first carbon block 400 facing the conductive roller 200 can be an arc surface, and the radian of the arc surface is consistent with the radian of the side wall surface of the conductive roller 200. Even if the first carbon block 400 is pressed to contact the side wall of the conductive roller 200, it can ensure good fit between the first carbon block 400 and the conductive roller 200 and have a good conductive effect.

[0051] Generally, the pressing component 500 can include: a fixed block 510, two first hinge members 520, a first tension spring 530, and a first conductive band 540.

[0052] The fixed block 510 is provided on the mounting plate 110. The two first hinge members 520 are symmetrically provided on the fixed block 510, and the two first hinge members 520 are respectively hinged to two adjacent first carbon blocks 400 located on the same circular line. The first tension spring 530 is provided between the two first hinge members 520, and its two ends are respectively connected to the two first hinge members 520. The first conductive band 540 is provided between the fixed block 510 and the mounting plate 110, and the two ends of the first conductive band 540 are respectively connected to two adjacent first carbon blocks 400 located on the same circular line.

[0053] As Figure 10As shown, two adjacent first carbon blocks 400 located on the same loop line are correspondingly arranged for each pressing assembly 500. Two symmetrical first hinge members 520 form a V shape under the pulling force of the first tension spring 530, driving the two first carbon blocks 400 to tightly press on the conductive ring 300, thereby increasing the contact force between the first carbon blocks 400 and the conductive ring 300, and further reducing the contact resistance between the first carbon blocks 400 and the conductive ring 300.

[0054] In the solution of this embodiment, both ends of the first conductive strip 540 are respectively connected to the two first carbon blocks 400, enabling the current on the first carbon blocks 400 to flow to the conductive strip, and realizing the smooth transmission of the current from the rotating conductive roller 200 to the stationary external circuit.

[0055] In some embodiments, the first hinge member 520 can be configured in an I shape, composed of two hinge rods and a connecting rod located between the two hinge rods. The two hinge rods are symmetrically arranged, with one end respectively symmetrically hinged on the two side walls of the fixed block 510, and the other end respectively symmetrically hinged on the two side wall surfaces of the first carbon block 400.

[0056] In some embodiments, the fixed block 510, the mounting plate 110, and the outer shell are all conductive, and the current can flow through the first conductive strip 540, the fixed block 510, the mounting plate 110, etc. to reach the conductive plate mounted on the mounting plate 110, and the current is output through the conductive plate.

[0057] In some other embodiments, the first conductive strip 540 can be directly connected to the stationary external circuit to output the current.

[0058] The two conductive rings 300 located at both ends of the conductive roller 200 are fixed relative to the conductive roller 200, and the remaining multiple conductive rings 300 move axially along the conductive roller 200 under the pressing of the first carbon blocks 400.

[0059] Such as Figure 11As shown, the conductive rings 300 and the first carbon blocks 400 are arranged alternately, and the first carbon blocks 400 are abutted against both sides of each conductive ring 300. When the pulling force of the first tension spring 530 on the first carbon block 400 on one side of the conductive ring 300 is too large, the first carbon block 400 will move inwards along the radial direction, and at the same time push the conductive ring 300 to move to the other side along the axial direction, thereby squeezing the first carbon block 400 on the other side to move outwards along the radial direction. During the movement of the conductive ring 300, the first carbon block 400 on one side of the conductive ring 300 gradually approaches the conductive roller 200 along the radial direction, and the pulling force it receives gradually decreases; the first carbon block 400 on the other side of the conductive ring 300 gradually moves away from the conductive roller 200 along the radial direction, and the pulling force it receives gradually increases. After the mechanical states of the conductive ring 300 and the first carbon blocks 400 on both sides of the conductive ring 300 reach relative equilibrium, the conductive ring 300 stops moving. At this time, the difference in the contact force between the first carbon blocks 400 on both sides of the conductive ring 300 and the conductive ring 300 has been reduced, avoiding the situation where the contact resistance is too large due to the too small contact force between a certain first carbon block 400 and the conductive ring 300, avoiding local overheating, reducing the risk of fire, and reducing potential safety hazards.

[0060] In addition, during the movement of the conductive ring 300, the change in the contact resistance caused by the change in the contact force of the first carbon block 400 is relatively small, and the change in the heat generated by its resistance is also relatively small. The change in the heat generated by the first carbon block 400 mainly comes from frictional heat generation. After the conductive ring 300 stops moving, due to the frictional resistance existing on the conductive ring 300 and the first carbon block 400, the contact force between the first carbon block 400 approaching the conductive roller 200 along the radial direction and the conductive ring 300 is actually greater than the contact force between the first carbon block 400 on the other side and the conductive ring 300. Therefore, during the movement of the conductive ring 300 and until the conductive ring 300 stops moving, the heat generated by the first carbon block 400 approaching the conductive roller 200 is always greater than the heat generated by the first carbon block 400 on the other side away from the conductive roller 200. The first carbon block 400 with a larger contact force approaches the conductive roller 200 and pushes the conductive ring 300 to move to the other side, resulting in an increase in the gap where the first carbon block 400 with a larger contact force is located. The improved heat dissipation efficiency just offsets its higher heat generation, thereby improving the operation reliability.

[0061] In the solution of this embodiment, except for the fixed conductive rings 300 at both ends, the remaining multiple conductive rings 300 can move freely under the extrusion of the first carbon blocks 400, so that the conductive rings 300 can automatically adjust their corresponding positions according to the magnitude of the abutting pressure received. The contact forces on each conductive ring 300 can reach a relatively balanced state, thereby reducing the non-uniformity of the contact forces between each conductive ring 300 and each first carbon block 400. Avoiding excessive contact resistance in a certain area leading to local overheating, reducing the risk of fire, and reducing potential safety hazards.

[0062] The solution of this embodiment improves the uniformity of the contact force between each conductive ring 300 and each first carbon block 400, making the contact resistance between each conductive ring 300 and the first carbon block 400 not vary much, thereby reducing the overall total heat generation of each conductive ring 300 and each first carbon block 400. This not only reduces the fire risk of the conductive roller structure and its accessories, but also avoids the aggravation of wear of the conductive ring 300 and the first carbon block 400, ensuring the service life of the conductive roller structure and its accessories.

[0063] A plurality of grooves 210 are provided on the conductive roller 200, and a plurality of support assemblies 600 are provided in the plurality of grooves 210. Each support assembly 600 is connected to a conductive ring 300. The plurality of support assemblies 600 support the plurality of conductive rings 300, enabling the plurality of conductive rings 300 to rotate under the drive of the conductive roller 200.

[0064] As Figure 2 shown, a plurality of grooves 210 are provided on the conductive roller 200, and the grooves 210 extend from one end of the conductive roller 200 to the other end.

[0065] On the inner sides of the conductive rings 300 at both ends, inwardly protruding clamping blocks 320 may be formed, and the clamping blocks 320 are snapped into the corresponding grooves 210, enabling the conductive rings 300 to rotate under the drive of the conductive roller 200. A plurality of support assemblies 600 are provided in the grooves 210, and the plurality of support assemblies 600 are connected to the plurality of conductive rings 300 except for those at both ends. Except for the conductive rings 300 at both ends, each conductive ring 300 is connected to at least one support assembly 600. When the conductive roller 200 rotates, the support assembly 600 drives the conductive ring 300 to rotate together.

[0066] In some embodiments, bolts may be provided on the clamping blocks 320 of the conductive rings 300 at both ends to fix them to the conductive roller 200.

[0067] As Figures 6 - 7 shown, the support assemblies 600 support the conductive rings 300 at intervals in the grooves 210 to avoid interference between adjacent support assemblies 600. The support assemblies 600 in the two opposite grooves 210 are staggeredly arranged, thereby realizing the support for all the conductive rings 300 while avoiding interference between the support assemblies 600.

[0068] In some preferred embodiments, the plurality of grooves 210 are evenly arranged in the circumferential direction of the conductive roller 200 to improve the overall structural stability of the conductive roller 200 and the conductive rings 300 sleeved on the conductive roller 200.

[0069] Generally, the support assembly 600 may include: a support block 610, two second hinge members 620, a second tension spring 630, two second carbon blocks 640, and a second conductive band 650.

[0070] The support block 610 is arranged inside the conductive ring 300. Two second hinge members 620 are symmetrically arranged on the support block 610. A second tension spring 630 is arranged between the two second hinge members 620, and its two ends are respectively connected to the two second hinge members 620. Two second carbon blocks 640 are arranged in the groove 210 and are respectively hinged to the two second hinge members 620. A second conductive belt 650 is arranged between the support block 610 and the conductive ring 300, and the two ends of the second conductive belt 650 are respectively connected to the two second carbon blocks 640.

[0071] In the solution of this embodiment, the two second hinge members 620 are pulled by the tension spring, so that the support block 610 is pressed tightly against the inner side of the conductive ring 300, and the structure is simple and stable. The second carbon block 640 and the conductive belt are arranged to better guide the current on the conductive roller 200 to the conductive ring 300 while completing the supporting function for the conductive ring 300, ensuring the current transmission effect. In addition, the conductive ring 300 will move axially under the pressing of the first carbon block 400. The arrangement of the second carbon block 640 not only ensures the conductive effect of the support assembly 600, but also can play a good lubricating effect, so that the support assembly 600 can smoothly move along the groove 210 under the drive of the conductive ring 300 while tightly supporting the conductive ring 300.

[0072] In some embodiments, the second hinge member 620 can be configured to be in an I shape and is composed of two hinge rods and a connecting rod located between the two hinge rods.

[0073] The conductive roller structure and its accessories generally may also include a plurality of cleaning assemblies 700.

[0074] A plurality of cleaning assemblies 700 are arranged on the outer periphery of a plurality of conductive rings 300 and correspond to the plurality of conductive rings 300 one by one, and are used to remove the oil stains on the wedge-shaped surfaces 310 of the plurality of conductive rings 300.

[0075] During the working process of the conductive roller structure and its accessories, oil stains may adhere to the wedge-shaped surfaces 310 of the conductive rings 300. The oil stains form an insulating layer on the wedge-shaped surfaces 310, resulting in an increase in the contact resistance between the conductive rings 300 and the first carbon blocks 400, thereby reducing the conductive performance of the conductive rings 300 and the first carbon blocks 400 and affecting the normal operation of the equipment.

[0076] In the solution of this embodiment, by arranging the cleaning assemblies 700 corresponding to the conductive rings 300 one by one, the oil stains on the wedge-shaped surfaces 310 of each conductive ring 300 are cleaned, avoiding the influence of the oil stains adhering to the wedge-shaped surfaces 310 of the conductive rings 300 on the conductive effect and ensuring the normal operation of the conductive roller structure and its accessories.

[0077] The cleaning component 700 generally may include a clip 710 and a support rod 720.

[0078] The clip 710 is clamped on the wedge surface 310 of the conductive ring 300 and is used to scrape off the oil stain on the wedge surface 310 of the conductive ring 300 when the clip 710 and the conductive ring 300 rotate relative to each other. The support rod 720 is connected to the clip 710 and is used to support the clip 710.

[0079] In the solution of this embodiment, by setting the clip 710 in a V shape and clamping the clip 710 on the conductive ring 300, and using the self-rotation of the conductive ring 300 to scrape off the oil stain attached to the wedge surface 310 of the conductive ring 300, it not only has a simple structure but also has a stable decontamination effect. Using the support rod 720 to support the clip 710 enables the clip 710 to better fit the conductive ring 300 and closely adhere to the wedge surface 310 of the conductive ring 300, further improving the cleaning effect of the clip 710.

[0080] In some preferred embodiments, the clip 710 may be composed of two blades connected by a torsion spring, and the elastic force of the torsion spring is used to make the clip 710 closely adhere to the conductive ring 300, thereby ensuring the decontamination effect.

[0081] In some preferred embodiments, the blades of the clip 710 are set to be wide at the part close to the axis of the conductive ring 300 and narrow at the part far from the axis of the conductive ring 300. That is to say, the blades of the clip 710 form a shape similar to an inverted triangle. When the conductive ring 300 rotates, the oil stain on the wedge surface 310 moves along the side wall of the clip 710 in the direction away from the axis of the conductive ring 300, so that while scraping off the oil stain, it avoids the oil stain flowing to the conductive roller 200 and causing secondary pollution.

[0082] In some embodiments, the support rod 720 is configured as a telescopic rod to ensure that the clip 710 can clamp the wedge surface 310 of the conductive ring 300, thereby improving the decontamination effect.

[0083] A chute 120 is provided at the bottom end of the housing 100, and the length direction of the chute 120 is consistent with the axial direction of the conductive roller 200. The support rod 720 is movably arranged in the chute 120 along the length direction of the chute 120.

[0084] In some embodiments, the conductive ring 300 can move axially along the conductive roller 200. By providing a chute 120 with a length direction consistent with the axial direction of the conductive roller 200 and enabling the support rod 720 to move along the length direction of the chute 120, when the conductive ring 300 moves axially, the support rod 720 can move accordingly with the wire ring, ensuring that the clamping piece 710 can always be clamped on the wedge-shaped surface 310 of the conductive ring 300, thus ensuring the decontamination effect. In addition, the chute 120 can also collect the oil stains scraped by the clamping piece 710, which can not only prevent the oil stains from polluting the housing 100, but also facilitate cleaning and maintenance.

[0085] In some embodiments, one or more openings can be provided on the housing 100 to facilitate the exchange of hot and cold air inside and outside the housing 100 for dissipating heat from the conductive roller 200.

[0086] The conductive roller structure and its accessories generally can also include an air extraction chamber 800.

[0087] The air extraction chamber 800 is provided on the housing 100 at one end of the conductive roller 200 and is used for extracting the air around the conductive roller 200.

[0088] In the solution of this embodiment, by providing the air extraction chamber 800 at one end of the conductive roller 200 and using the air extraction chamber 800 to extract the air around the conductive roller 200, the flow rate of the air around the conductive roller 200 is increased, thereby improving the heat dissipation efficiency.

[0089] In some embodiments, an air extraction pump can be provided in the air extraction chamber 800, or the air extraction chamber 800 is directly connected to an air extraction pump.

[0090] In some preferred embodiments, the air extraction chamber 800 can be provided at one end where the groove 210 is opened, so that the air around the conductive roller 200 can flow through the first carbon block 400 and the conductive ring 300 and then flow into the air extraction chamber 800 through the groove 210, making the air flow more smooth, thereby further improving the heat dissipation efficiency.

[0091] Combined with the above embodiments, the specific working process of the conductive roller structure and its accessories provided by the present invention is described as follows:

[0092] The conductive roller 200 starts to rotate, driving the conductive ring 300 to rotate through the support assembly 600. Under the extrusion of the pressing assembly 500, the first carbon block 400 abuts against the wedge-shaped surface 310 of the conductive ring 300, and the conductive ring 300 and the first carbon block 400 rotate relative to each other. The current on the conductive roller 200 is transmitted to the conductive ring 300 through the support assembly 600, and then transmitted to the first carbon block 400, and thus conveyed to the stationary external circuit.

[0093] During the relative rotation of the conductive ring 300 and the first carbon block 400, each first carbon block 400 experiences different degrees of wear, causing the contact force between each first carbon block 400 and the corresponding conductive ring 300 to change to varying degrees. Due to the changes in the contact force between each first carbon block 400 and each conductive ring 300, each conductive ring 300 moves axially under the pressing of each first carbon block 400 until each conductive ring 300 and each first carbon block 400 reach a new equilibrium state. During the axial movement of the conductive ring 300, the cleaning assembly 700 slides accordingly as the conductive ring 300 moves axially, ensuring that the clamping piece 710 of the cleaning assembly 700 always clamps on the wedge surface 310 of the corresponding conductive ring 300 to scrape off the oil stains on the wedge surface 310.

[0094] Each conductive ring 300 adjusts its own position in real time according to the actual situation, enabling each conductive ring 300 and each first carbon block 400 to always be in a relatively balanced state, thereby reducing the non-uniformity of the contact force between each conductive ring 300 and each first carbon block 400. This not only avoids fires caused by local overheating but also reduces the overall total heat generation of each conductive ring 300 and each first carbon block 400, further reducing potential safety hazards and ensuring the service life of the conductive roller structure and its accessories.

[0095] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0096] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
