Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of electrical equipment technology, and more specifically, to a dual power transfer switch. Background Technology

[0002] Dual power transfer switches are important low-voltage electrical switches widely used in critical loads where power outages are unacceptable, such as in hospitals, airports, and fire stations. They contain an internal operating mechanism that allows for switching between operating modes.

[0003] However, during the switching of the operating mode of a conventional dual power transfer switch, the action time of the operating mechanism is relatively long, which increases the switching time of the dual power transfer switch. Summary of the Invention

[0004] The purpose of this disclosure is to provide a dual power transfer switch to at least partially solve the above-mentioned problems.

[0005] In one aspect of this disclosure, a dual-power transfer switch is provided, comprising a pair of moving contact assemblies; a pair of rotating members, each including a first end and a second end located on opposite sides of a rotation shaft, the first ends of the pair of rotating members being adjacent to each other, the rotation shafts of the pair of rotating members being connected to a corresponding moving contact assembly and capable of driving the corresponding moving contact assembly to rotate; a pair of locking members, each cooperating with the second end of a corresponding rotating member to lock the second end of the corresponding rotating member; and a drive assembly including a first pair of actuating members and a second pair of actuating members respectively disposed along a first direction and movable along the first direction, the first pair of actuating members and the second pair of actuating members each being capable of cooperating with the first end of a corresponding rotating member and each including an elastic member, wherein the first pair of actuating members and the second pair of actuating members are movable in the same direction along the first direction, wherein when the second end of the pair of rotating members is locked, the corresponding elastic member in the first pair of actuating members and the second pair of actuating members is compressed, and when the corresponding rotating member is unlocked, the corresponding rotating member is driven by the corresponding compressed elastic member.

[0006] According to embodiments of this disclosure, when the first pair of actuating members and the second pair of actuating members are moved while the dual power supply changeover switch is in the first power-on position or the second power-on position, the second ends of the paired rotating members are locked by the corresponding locking members and cannot rotate. Therefore, the corresponding elastic members in the first pair of actuating members and the second pair of actuating members are compressed. When the corresponding rotating members are unlocked, the corresponding rotating members can be driven by the corresponding compressed elastic members, thereby driving the corresponding moving contact assembly to rotate, thus completing the state switching. In this way, embodiments of this disclosure can drive the moving contact assembly to complete the state switching through the cooperation of elastic members, paired locking members, and paired rotating members, reducing the number of parts and simplifying the transmission process, thereby reducing the switching time of the dual power supply changeover switch.

[0007] In some embodiments, the drive assembly further includes a housing, and the first pair of actuating members and the second pair of actuating members each include a mating member, one end of the mating member engaging with the first end of the corresponding rotating member, the other end of the mating member opposite to the corresponding rotating member being connected to the housing, and the elastic member being disposed on the corresponding mating member and capable of driving the corresponding mating member.

[0008] In some embodiments, the mating member includes: a main body portion including a first receiving hole disposed on one end of the main body portion opposite to a corresponding rotating member; a first fixed shaft passing through the first receiving hole and connected to the housing; and a pair of connecting portions disposed around the main body portion, the elastic member being disposed around a corresponding main body portion and located between the corresponding pair of connecting portions, one of the connecting portions of the pair of connecting portions engaging with the main body portion, and the other connecting portion of the pair of connecting portions engaging with the first fixed shaft.

[0009] In some embodiments, the main body further includes a sliding shaft disposed on one end of the main body adjacent to a corresponding rotating member to cooperate with the corresponding rotating member, the housing includes a pair of second receiving holes, and the sliding shafts of the first pair of actuating members and the second pair of actuating members are each located in a corresponding second receiving hole.

[0010] In some embodiments, the main body further includes a limiting step, which is disposed on one end of the main body adjacent to a corresponding rotating member and is capable of abutting against one of the paired connecting portions.

[0011] In some embodiments, each of the paired locking members includes a driving member, a latching member, and a second fixed shaft. The latching member is arranged around the second fixed shaft to rotate about the second fixed shaft under the drive of the driving member, and the latching member can engage with the second end of the corresponding rotating member.

[0012] In some embodiments, the latching member includes a first locking protrusion, and the rotating member includes a second locking protrusion disposed on the second end, wherein the first locking protrusion is capable of contacting the opposite sides of the second locking protrusion to lock the corresponding rotating member.

[0013] In some embodiments, the dual power transfer switch further includes an actuation component that cooperates with the drive component and is capable of driving the drive component to move along the first direction, thereby driving the first pair of actuating elements and the second pair of actuating elements to move along the first direction.

[0014] In some embodiments, the actuation assembly includes a gear shaft and a pair of gears, the gear shaft passing through the pair of gears, and the drive assembly further includes a pair of actuation plates, each of the pair of actuation plates including an actuation hole, each of the pair of gears including an actuation portion, and the actuation portion of each of the pair of gears being spaced apart from each other from the corresponding gear shaft and engaging with the hole wall of the corresponding actuation hole.

[0015] In some embodiments, the drive assembly further includes a pair of mounting plates that clamp the housing, the housing further including a pair of third receiving holes, each of the pair of mounting plates including a mounting hole, the gear shaft passing through the pair of third receiving holes and connected to the mounting holes of the pair of mounting plates.

[0016] It should be understood that the description in this section is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0036] As described above, the operating mechanism takes a relatively long time to operate during the switching process of a conventional dual-power transfer switch, thus increasing the switching time. Embodiments of this disclosure provide a dual-power transfer switch 100 to at least partially solve the above-mentioned problems. In the following, [further details will be provided]. Figures 1 to 13 The principles of this disclosure are described.

[0037] Figure 1 A schematic diagram of the structure of a dual power supply transfer switch 100 according to some embodiments of the present disclosure is shown. Figure 2 A schematic diagram of the structure of the rotating member 2, the locking member 3, the driving assembly 4, and the actuating assembly 5 according to some embodiments of the present disclosure is shown. Figure 3 An exploded view of a rotating member 2, a locking member 3, a driving assembly 4, and an actuating assembly 5 according to some embodiments of the present disclosure is shown.

[0038] Figure 4 A partial structural schematic diagram of the drive component 4 according to some embodiments of the present disclosure is shown.

[0039] Figure 5 A schematic diagram of the moving contact assembly 1 and the rotating member 2 according to some embodiments of the present disclosure is shown. Figure 6 A schematic diagram of the drive assembly 4 and actuation assembly 5 according to some embodiments of the present disclosure is shown. Figures 1 to 6 As shown, the dual power transfer switch 100 described herein generally includes a pair of moving contact assemblies 1, a pair of rotating members 2, a pair of locking members 3, a drive assembly 4, an actuation assembly 5, and a pair of stationary contact assemblies 6. The drive assembly 4 and the actuation assembly 5 are located between the pair of stationary contact assemblies 6. The pair of locking members 3 are each located on opposite sides of the drive assembly 4 and are also located between the pair of stationary contact assemblies 6.

[0040] refer to Figures 1 to 3 as well as Figure 5In some embodiments, each rotating member 2 may include a first end 21, a second end 22, and a rotating shaft 23. The first end 21 and the second end 22 may be located on opposite sides of the rotating shaft 23. The first ends 21 of the paired rotating members 2 are adjacent to each other, and the second ends 22 of the paired rotating members 2 are opposite to each other. The rotating shaft 23 of the paired rotating members 2 is connected to a corresponding moving contact assembly 1, so that during the rotation of each rotating member 2, the rotating shaft 23 can drive the corresponding moving contact assembly 1 to rotate, thereby making or breaking the connection between the moving contact assembly 1 and the stationary contact assembly 6.

[0041] Continue to refer to Figure 1 and Figure 5 Furthermore, the paired moving contact assembly 1 may include a first pair of moving contact assemblies and a second pair of moving contact assemblies. The two ends of the rotation shaft 23 of one of the paired rotating members 2 are each connected to the first pair of moving contact assemblies, and the two ends of the rotation shaft 23 of the other rotating member 2 are each connected to the second pair of moving contact assemblies. The first pair of moving contact assemblies and the second pair of moving contact assemblies may each include a first moving contact 11 and a second moving contact 12.

[0042] Correspondingly, each stationary contact assembly 6 may include a first stationary contact 61, a second stationary contact 62, a third stationary contact 63, and a fourth stationary contact 64. The first moving contact 11 of the first pair of moving contact assemblies can cooperate with the first stationary contact 61, and the second moving contact 12 of the first pair of moving contact assemblies can cooperate with the second stationary contact 62. The first moving contact 11 of the second pair of moving contact assemblies can cooperate with the fourth stationary contact 64, and the second moving contact 12 of the second pair of moving contact assemblies can cooperate with the third stationary contact 63. Therefore, the dual-power transfer switch 100 of this embodiment, through its two-sided conduction design, can improve overall synchronization and optimize the stress on internal components.

[0043] It should be noted that when the first moving contact 11 of the first pair of moving contact assemblies is in contact with the first stationary contact 61, and the second moving contact 12 of the first pair of moving contact assemblies is in contact with the second stationary contact 62, the dual power supply changeover switch 100 is in the first power-on position because the first stationary contact 61 and the second stationary contact 62 can be connected to the first power supply (not shown in the figure). Furthermore, to avoid the risk of a short circuit in the dual power supply changeover switch 100, the first moving contact 11 of the second pair of moving contact assemblies needs to be disconnected from the fourth stationary contact 64, and the second moving contact 12 of the second pair of moving contact assemblies needs to be disconnected from the third stationary contact 63.

[0044] Similarly, when the first moving contact 11 of the second pair of moving contact assemblies is in contact with the fourth stationary contact 64, and the second moving contact 12 of the second pair of moving contact assemblies is in contact with the third stationary contact 63, since the third stationary contact 63 and the fourth stationary contact 64 can be connected to the second power supply (not shown in the figure), the dual power supply changeover switch 100 is in the second power supply on position, and the first moving contact 11 of the first pair of moving contact assemblies needs to be disconnected from the first stationary contact 61, and the second moving contact 12 of the first pair of moving contact assemblies needs to be disconnected from the second stationary contact 62.

[0045] Of course, when the first moving contact 11 of the first pair of moving contact assemblies is disconnected from the first stationary contact 61, the second moving contact 12 of the first pair of moving contact assemblies is disconnected from the second stationary contact 62, and the first moving contact 11 of the second pair of moving contact assemblies is disconnected from the fourth stationary contact 64, and the second moving contact 12 of the second pair of moving contact assemblies is disconnected from the third stationary contact 63, the dual power supply changeover switch 100 is in the dual open position.

[0046] Continue reading Figures 1 to 2 as well as Figure 5 In some embodiments, the pair of locking members 3 each cooperate with the second end 22 of the corresponding rotating member 2 to lock or unlock the second end 22 of the corresponding rotating member 2.

[0047] Continue to refer to Figures 1 to 3 as well as Figure 6 In some embodiments, the drive assembly 4 may include a housing 41, a first pair of actuating members 42, a second pair of actuating members 43, a pair of actuating plates 45, and a pair of mounting plates 46. The pair of mounting plates 46 clamp the housing 41, and the rotating shaft 23 can pass through the pair of mounting plates 46 and be connected to the corresponding moving contact assembly 1. The pair of actuating plates 45 are each disposed on the side of the corresponding mounting plate 46 opposite to the housing 41. At least a portion of the first pair of actuating members 42 and the second pair of actuating members 43 is located within the housing 41. The first pair of actuating members 42 and the second pair of actuating members 43 are respectively disposed along a first direction X and are movable along the first direction X. The first pair of actuating members 42 and the second pair of actuating members 43 are each capable of engaging with the first end 21 of the corresponding rotating member 2 and each includes an elastic member 442.

[0048] Continue to refer to Figures 3 to 4 Furthermore, the housing 41 may include a pair of first side plates 411 and a pair of second side plates 412. The pair of first side plates 411 are spaced apart from each other, and the pair of second side plates 412 are spaced apart from each other. A mounting plate 46 is disposed on the outer surface of the respective first side plate 411. Each of the pair of second side plates 412 is provided with a through hole 4121 for the rotating member 2 to pass through the housing 41.

[0049] Figures 7 to 13A schematic diagram of the switching of a dual power supply transfer switch 100 according to some embodiments of the present disclosure is shown. For example... Figures 7 to 13 As shown, in some embodiments, the first pair of actuating members 42 and the second pair of actuating members 43 are capable of moving in the same direction along the first direction X. When the second end 22 of the pair of rotating members 2 is locked, the first end 21 of the pair of rotating members 2 is locked and cannot rotate, so the corresponding elastic members 442 in the first pair of actuating members 42 and the second pair of actuating members 43 can be compressed, and when the corresponding rotating member 2 is unlocked, the corresponding rotating member 2 can be driven by the corresponding compressed elastic member 442.

[0050] According to embodiments of this disclosure, when the first pair of actuating members 42 and the second pair of actuating members 43 are moved while the dual power supply switch 100 is in the first power-on position or the second power-on position, the second ends 22 of the paired rotating members 2 are locked by the corresponding locking members 3 and cannot rotate. Therefore, the corresponding elastic members 442 in the first pair of actuating members 42 and the second pair of actuating members 43 are compressed. When the corresponding rotating members 2 are unlocked, the corresponding rotating members 2 can be driven by the corresponding compressed elastic members 442, thereby driving the corresponding moving contact assembly 1 to rotate, so as to complete the state switching.

[0051] In summary, the embodiments of this disclosure can drive the moving contact assembly 1 to complete the state switching by cooperating with the elastic element 442, the paired locking elements 3 and the paired rotating elements 2, and reduce the number of parts and simplify the transmission process, thereby reducing the switching time of the dual power supply changeover switch 100.

[0052] refer to Figure 2 , Figure 3 as well as Figure 7 In some embodiments, the drive assembly 4 is movable along a first direction X. The first pair of actuating members 42 and the second pair of actuating members 43 each also include a mating member 441. One end of the mating member 441 engages with the first end 21 of the corresponding rotating member 2, and the other end of the mating member 441 opposite to the corresponding rotating member 2 is connected to the housing 41. An elastic member 442 is disposed on the corresponding mating member 441 and is capable of driving the corresponding mating member 441.

[0053] Using the above configuration, refer to Figures 7 to 8 During the movement of the drive assembly 4 along the first direction X, the first pair of actuating members 42 and the second pair of actuating members 43 can move in the same direction along the first direction X. However, due to the blocking of the corresponding mating member 441 by the locked rotating member 2, the corresponding mating member 441 cannot move. Therefore, the elastic member 442 can be compressed and store energy.

[0054] refer to Figure 2 , Figure 3 as well as Figure 7 Furthermore, the mating member 441 may include a main body portion 4411. The main body portion 4411 may include a first receiving hole 4412, a first fixed shaft 4413, and a pair of connecting portions 4414. The first receiving hole 4412 may be provided on one end of the main body portion 4411 opposite to the corresponding rotating member 2. The first fixed shaft 4413 may pass through the first receiving hole 4412 and be fixedly connected to the housing 41. The pair of connecting portions 4414 may be provided around the main body portion 4411, and the elastic member 442 may be provided around the corresponding main body portion 4411 and located between the corresponding pair of connecting portions 4414. One of the connecting portions 4414 in the pair of connecting portions 4414 may mate with the main body portion 4411, and the other connecting portion 4414 in the pair of connecting portions 4414 may mate with the first fixed shaft 4413.

[0055] Using the above configuration, refer to Figures 7 to 8 As the drive assembly 4 moves along the first direction X, the first fixed shaft 4413 follows the housing 41 along the first receiving hole 4412. During the movement of the first fixed shaft 4413, it can press the connecting part 4414 that mates with it. Because the locked rotating member 2 blocks the corresponding mating member 441, preventing the mating member 441 from moving, the first fixed shaft 4413 can compress the corresponding elastic member 442.

[0056] refer to Figure 4 and Figure 7 In some embodiments, the main body 4411 may further include a sliding shaft 4415. The sliding shaft 4415 may be disposed on one end of the main body 4411 adjacent to the corresponding rotating member 2 to engage with the corresponding rotating member 2. The housing 41 may include a pair of second receiving holes 4111, which may be disposed on the corresponding first side plate 411. The sliding shafts 4415 of the first pair of actuating members 42 and the sliding shafts 4415 of the second pair of actuating members 43 are each located within the corresponding second receiving holes 4111, and the sliding shafts 4415 of the first pair of actuating members 42 and the sliding shafts 4415 of the second pair of actuating members 43 are movable along the corresponding second receiving holes 4111.

[0057] Continue to refer to Figure 7 In some embodiments, the main body 4411 may further include a limiting step 4416. The limiting step 4416 may be disposed on one end of the main body 4411 adjacent to the corresponding rotating member 2 and may abut against one of the connecting portions 4414 of the pair of connecting portions 4414. Obviously, since one of the connecting portions 4414 of the pair of connecting portions 4414 is limited by the limiting step 4416, the corresponding elastic member 442 can be compressed during the process of the first fixed shaft 4413 pressing the other connecting portion 4414 of the pair of connecting portions 4414.

[0058] Return to reference Figure 3 In some embodiments, the locking member 3 may include a driving member 31, a latching member 32, and a second fixed shaft 33. Both ends of the second fixed shaft 33 are connected to corresponding mounting plates 46 for fixed connection. The latching member 32 may be arranged around the second fixed shaft 33 to rotate around it under the drive of the driving member 31. The latching member 32 can engage with the second end 22 of the corresponding rotating member 2, thus locking or unlocking the rotating member 2 during its rotation around the second fixed shaft 33.

[0059] According to embodiments of this disclosure, the driving member 31 can be of various types known or available in the future, as long as it can drive the latching member 32 to rotate. Embodiments of this disclosure do not limit this. For example, in some embodiments, the driving member 31 may include an electromagnet and a moving iron core located within the electromagnet, the electromagnet being able to drive the moving iron core to move when energized.

[0060] refer to Figure 5 and Figure 7 In some embodiments, the latching member 32 may include a first locking protrusion 321. The rotating member 2 may include a second locking protrusion 221 disposed on the second end 22. The first locking protrusion 321 is capable of contacting the opposite sides of the second locking protrusion 221 to lock the corresponding rotating member 2 and prevent the corresponding rotating member 2 from rotating.

[0061] Return to reference Figures 2 to 3 as well as Figure 6 In some embodiments, the actuation component 5 cooperates with the drive component 4 and is capable of moving the drive component 4 along a first direction X, thereby driving the first pair of actuating members 42 and the second pair of actuating members 43 to move along the first direction X. The actuation component 5 may include a gear shaft 51 and a pair of gears 52. Each gear 52 in the pair of gears 52 may be disposed between a corresponding mounting plate 46 and a corresponding actuation plate 45. The gear shaft 51 may pass through the pair of gears 52 and be connected to the pair of mounting plates 46. Each pair of actuation plates 45 includes an actuation hole 451, and each pair of gears 52 includes an actuating portion 521, and the actuating portions 521 of each pair of gears 52 are spaced apart from each other from the corresponding gear shaft 51 and are capable of cooperating with the hole wall of the corresponding actuation hole 451.

[0062] It is understood that during the half-turn rotation of gear 52, since each actuating part 521 is spaced apart from the corresponding gear shaft 51, the actuating part 521 can contact the hole wall of the corresponding actuating hole 451 and drive the actuating plate 45 to move, thereby driving the drive assembly 4 to move along the first direction X. In some embodiments, the operator can rotate gear 52 by means of a handle. In other embodiments, the operator can also start a motor to drive gear 52 to rotate. No limitation is made here.

[0063] Return to reference Figures 3 to 4 In some embodiments, the housing 41 further includes a pair of third receiving holes 4112 disposed on the respective first side plate 411 and may be located between the pair of second receiving holes 4111. Each of the pair of mounting plates 46 includes a mounting hole 461. The gear shaft 51 may pass through the pair of third receiving holes 4112 and connect to the mounting holes 461 of the pair of mounting plates 46.

[0064] It should be noted that the third receiving hole 4112 may include an oblong hole. Since the gear 52 can only rotate and cannot move, and the gear shaft 51 also cannot move, the gear shaft 51 will not interfere with the third receiving hole 4112 during the movement of the drive assembly 4 along the first direction X, thereby preventing the gear shaft 51 from blocking the movement of the drive assembly 4.

[0065] In some embodiments, the gear shaft 51 may be fixedly connected within the mounting hole 461, so the gear shaft 51 cannot rotate with the gear 52, and the gear 52 rotates around the gear shaft 51. In other embodiments, a bearing (not shown) may also be provided within the mounting hole 461, and the gear shaft 51 may cooperate with the bearing, so the gear shaft 51 can rotate with the gear 52.

[0066] The following will combine Figures 7 to 13 To describe the state switching process of the dual power supply transfer switch 100, wherein... Figures 7 to 10 This describes the process by which the dual power supply transfer switch 100 switches from the first power-on position to the dual-disconnect position. (The text then repeats the description of the process, which is not directly related to the initial description of the dual power supply transfer switch 100.) Figures 10 to 12 This describes the process by which the dual power supply transfer switch 100 switches from the dual open position to the second power on position.

[0067] like Figure 3 and Figure 7 As shown, when the dual power supply switch 100 is in the first power-on position, the sliding shaft 4415 of the first pair of actuating members 42 clamps the first end 21 of the corresponding rotating member 2, and the sliding shaft 4415 of the second pair of actuating members 43 also clamps the first end 21 of the corresponding rotating member 2. The first locking protrusion 321 contacts the upper surface of the corresponding second locking protrusion 221 so that the second end 22 of the rotating member 2 is locked by the corresponding latching member 32.

[0068] like Figure 8 As shown, the actuation component 5 drives the drive component 4 to move downward along the first direction X, and the first pair of actuating members 42 and the second pair of actuating members 43 can move in the same direction along the first direction X. However, since one of the actuating members 42 located on the upper side of the paired rotating members 2 is limited by the corresponding rotating member 2 and cannot move, and one of the actuating members 43 located on the upper side of the paired rotating members 2 is limited by the corresponding rotating member 2 and cannot move, the first fixed shaft 4413 can press the corresponding connecting part 4414 and compress the corresponding elastic member 442.

[0069] like Figure 9 As shown, the driving member 31 on the right drives the corresponding latching member 32 to rotate around the second fixed shaft 33. When the first locking protrusion 321 rotates to a position that is offset from the second locking protrusion 221, the rotating member 2 released by the latching member 32 can rotate counterclockwise under the action of the elastic member 442. Therefore, the rotating shaft 23 can drive the moving contact of the corresponding moving contact assembly 1 to rotate away from the stationary contact, so that the dual power supply changeover switch 100 switches to the dual open position.

[0070] like Figure 10 As shown, the latching member 32 can be reset under the action of a torsion spring or a spring, and the first locking protrusion 321 can be rotated to a position that contacts the lower surface of the second locking protrusion 221, so that the second end 22 of the corresponding rotating member 2 is locked by the corresponding latching member 32, and the dual power supply changeover switch 100 is switched to the dual-position.

[0071] For example, in some embodiments, a torsion spring (not shown) may be disposed on the second fixed shaft 33 and connected to the latching member 32, so that the torsion spring can deform and store energy when the latching member 32 rotates about the second fixed shaft 33. In other embodiments, a spring (not shown) may be disposed on the latching member 32, so that the spring can be compressed and store energy when the latching member 32 rotates about the second fixed shaft 33.

[0072] like Figure 11 As shown, the driving member 31 on the left drives another latching member 32 to rotate around the second fixed shaft 33, and the first locking protrusion 321 rotates to a position offset from the second locking protrusion 221. The rotating member 2 released by the latching member 32 can rotate clockwise under the action of the elastic member 442. Therefore, the rotating shaft 23 can drive the moving contact of the corresponding moving contact assembly 1 to rotate toward the stationary contact, so that the dual power supply changeover switch 100 switches to the second power supply on position.

[0073] like Figure 12As shown, the latching member 32 can be reset under the action of a torsion spring or a spring, and the first locking protrusion 321 rotates to a position that contacts the lower surface of the second locking protrusion 221, so that the second end 22 of the corresponding rotating member 2 is locked by the corresponding latching member 32, and the dual power supply switch 100 switches to the second power supply on position.

[0074] It should be noted that, as Figure 13 As shown, if the dual power supply switch 100 is to be switched from the second power supply position to the first power supply position, the actuating component 5 needs to drive the driving component 4 to move upward along the first direction X, so that one of the elastic elements 442 of the first pair of actuating elements 42 and one of the elastic elements 442 of the second pair of actuating elements 43 located on the lower side of the paired rotating elements 2 are compressed. Other processes are the same as or similar to those described above, and will not be repeated here.

It should be understood that the operating mechanism according to embodiments of this disclosure can also be applied to other electrical components, and embodiments of this disclosure do not limit this application.
