Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to a dual-power supply conversion switch. Background Art

[0002] The dual power transfer switch generally includes a base, and a controller, a transmission mechanism and an execution switch (which may be a circuit breaker) installed on the base. The transmission mechanism drives the execution switch to perform opening and closing operations according to the operation of the controller or handle.

[0003] At present, the base is generally a flat plate structure, and the controller is directly fixed on the base by screws. Since the controller is generally sandwiched between two execution switches and one side is abutted against the cover of the dual power conversion switch, only one side of the controller shell can be provided with a screw hole, which makes the stability of the controller installation poor. Although the installation of the controller can be assisted by providing a clamping structure on the base that is clamped with the bottom of the controller shell to improve the stability of the controller installation, for a base made of metal material, the processing difficulty and processing cost of providing the clamping structure are relatively high.

[0004] Therefore, it is urgent to propose a dual power conversion switch to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0067] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0068] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0070] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0071] This embodiment provides a dual power conversion switch, which fixes the controller on the base by setting a controller installation base, thereby improving the stability of the controller installation, and has a simple structure, which facilitates the installation of the controller.

[0072] Specifically, Figure 1 As shown, the dual power conversion switch includes a base 100, a controller mounting base 200 and a controller 300. The base 100 is provided with a controller mounting area. The controller mounting base 200 is detachably mounted on the controller mounting area, and a mounting limit portion is provided on the controller mounting base 200. The controller 300 is mounted on the mounting limit portion.

[0073] The dual power conversion switch realizes the connection between the controller 300 and the base 100 through the controller mounting base 200. Compared with the solution in the prior art that the controller 300 is directly fixed on the base 100 by a screw, the installation stability of the controller 300 is greatly improved. In addition, the installation of the controller 300 is also relatively simple. By fixing the controller 300 through the controller mounting base 200, the clamping structure set on the base 100 can be omitted, reducing the processing difficulty and processing cost of the base 100. The controller 300 can also be raised by the controller mounting base 200, which has the effect of adjusting the height of the controller 300 and can meet the installation height requirements of the controller 300.

[0074] Optionally, continue to see Figure 1 In this embodiment, the dual power conversion switch further includes a common circuit breaker 410 and a backup circuit breaker 420, which are mounted on the base 100, and the controller installation area is arranged between the common circuit breaker 410 and the backup circuit breaker 420, and the controller installation base 200 can block the gap between the common circuit breaker 410 and the backup circuit breaker 420 to improve the dustproof effect of the dual power conversion switch. The controller installation area is arranged between the common circuit breaker 410 and the backup circuit breaker 420, which is also convenient for arranging the lines between the controller 300 and the common circuit breaker 410 and the backup circuit breaker 420.

[0075] Alternatively, if Figure 2 and Figure 3 As shown, in this embodiment, a plurality of first mounting holes 110 are provided on the controller mounting area, and a plurality of second mounting holes 210 are provided on the controller mounting base 200, and the second mounting holes 210 are arranged one by one with the first mounting holes 110 to form a plurality of pairs of mounting hole groups, and a first connecting member (not shown in the figure) is arranged corresponding to each pair of mounting hole groups, and the first connecting member fixes the controller mounting base 200 on the base 100 through the first mounting hole 110 and the second mounting hole 210. With such an arrangement, the connection strength between the controller mounting base 200 and the base 100 is relatively high, and the stability of the installation of the controller 300 is improved.

[0076] Optionally, the first connecting member may be a bolt and nut assembly, which has a simple structure and is convenient for installing and removing the controller mounting base 200 .

The cooperation between the anti-fool boss 220 and the anti-fool hole 104 can pre-install the controller installation base 200 and the base 100. On the one hand, it plays a role in positioning the controller installation base 200 and improves the installation efficiency of the controller installation base 200; on the other hand, it can effectively avoid the first installation hole 110 and the second installation hole 210 from being skewed when installing the first connecting member, which is convenient for the assembly of the first connecting member and reduces the difficulty of installing the controller installation base 200.

[0078] Optionally, in this embodiment, two foolproof holes 104 are provided, and the two foolproof holes 104 are spaced apart along the length direction of the base 100, and the diameters of the two foolproof holes 104 are different. By providing two foolproof holes 104, and by spaced apart along the length direction of the base 100, the number of foolproof holes 104 is reduced as much as possible while ensuring reliable fixing of the controller mounting base 200, thereby simplifying the structure of the base 100 and the controller mounting base 200. By providing two foolproof holes 104 with different diameters, a foolproof effect can be achieved, ensuring that the controller mounting base 200 can be installed in place at one time, thereby greatly improving the installation efficiency of the controller mounting base 200.

The controller 300 can be limited by the first mounting groove 230, and the controller 300 can be reliably fixed on the controller mounting base 200 through the cooperation between the first clamping portion 240 and the second clamping portion 310, and the cooperation between the third mounting hole 250, the fourth mounting hole 320 and the second connecting member.

When installing the controller 300, the controller 300 is first placed on the bottom wall of the first mounting groove 230 from the side of the first mounting groove 230 having the side opening, and then the controller 300 is pushed until the second clamping portion 310 on the controller 300 is clamped to the first clamping portion 240. At this time, the controller 300 moves into place, the fourth mounting hole 320 corresponds to the third mounting hole 250, and then the second connecting member is installed to complete the installation of the controller 300.

In this embodiment, the first clamping portion 240 is a first clamping groove, and the second clamping portion 310 is a first clamping protrusion. Of course, in other embodiments, the structures of the first clamping portion 240 and the second clamping portion 310 can also be set to other structures, such as a buckle and a first clamping protrusion, etc., according to actual needs, and this application does not make specific limitations.

[0082] Furthermore, the number of the first clamping parts 240 can also be multiple, and each first clamping part 240 is correspondingly provided with a second clamping part 310. By providing multiple first clamping parts 240 and multiple second clamping parts 310, the connection strength between the controller 300 and the controller mounting base 200 can be improved, thereby improving the stability of the installation of the controller 300.

[0083] Furthermore, the number of the third mounting holes 250 may be multiple, and each third mounting hole 250 may correspond to a fourth mounting hole 320 and a second connecting member. In this way, the stability of the installation of the controller 300 may be improved.

The line layout of the standby side sampling line 340 is restricted by the standby side wire inlet hole 140 and the standby side wire outlet hole 150, so that the wiring of the standby side sampling line 340 is more regular, and it is also convenient to connect the standby side sampling line 340 with the standby side wiring terminals 421.

[0089] In this embodiment, a common side wire inlet hole 120 and a plurality of common side wire outlet holes 130 are provided on the base 100, and the common side wire outlet holes 130 are arranged in a one-to-one correspondence with the common side wiring terminals 411.

[0098] It is understandable that the spare side binding strap 360 may be selected but not limited to a cable tie, which is easy to install and has better binding reliability.

[0099] Optionally, the number of the spare-side fixing ribs 170 can be set according to actual needs, for example, one, two or three, etc., which is not specifically limited in the present application.

[0100] Further, see Figure 7 A side protective cover 380 can be used on the part of the outer jacket of the spare side sampling line 340 between the spare side line inlet hole 140 and the spare side line outlet hole 150.

In this way, the spare side sampling line 340 can be effectively protected, which can not only extend the service life of the spare side sampling line 340, but also improve the regularity of the wiring.

[0101] Optionally, in this embodiment, the spare side protective cover 380 is formed by winding a protective winding wire. With this arrangement, the installation of the spare side protective cover 380 is more convenient.

[0102] Optionally, continue to attend Figure 7 The base 100 is also provided with a plurality of weight-reducing holes 102 and a plurality of weight-reducing grooves 103. The arrangement of the weight-reducing holes 102 and the weight-reducing grooves 103 can reduce the weight of the base 100 and reduce the cost of the base 100.

[0103] Further, see Figure 2 In one possible embodiment, a common side positioning hole is provided at the bottom of the common circuit breaker 410, and a common side positioning convex bump 180 is provided on the base 100 to be plugged into and matched with the common side positioning hole.

At the same time, a spare side positioning hole is provided at the bottom of the spare circuit breaker 420, and a spare side positioning convex bump 190 is provided on the base 100 to be plugged into and matched with the spare side positioning hole.

[0105] Furthermore, if Fig. 9 and Fig.10 As shown, the dual power conversion switch further includes an upper cover 500 and a conversion handle 600. A handle mounting structure is provided on one side of the upper cover 500, and the handle mounting structure is used to fix the conversion handle 600. The conversion handle 600 is used for manual operation to realize the conversion between the normal power supply and the backup power supply. Fixing the handle on the upper cover 500 not only facilitates the taking and placing of the conversion handle 600, but also reduces the risk of losing the conversion handle 600.

[0106] Alternatively, if Figure 9-13 As shown, the handle mounting structure includes a second mounting groove 510, a second clamping groove 520, a second clamping protrusion 530 and an elastic clamping buckle 540. The second clamping groove 520 is arranged in the second mounting groove 510. The second clamping protrusion 530 is arranged on the inner wall of the second mounting groove 510. The elastic clamping buckle 540 is arranged at the side opening of the upper cover 500 close to the second mounting groove 510. The elastic clamping buckle 540 and the second clamping protrusion 530 are arranged on opposite sides of the second mounting groove 510. The conversion handle 600 is installed in the second mounting groove 510. The conversion handle 600 includes a handle portion 610 and a driving portion 620 arranged at one end of the handle portion 610. The driving portion 620 is clamped in the second clamping groove 520. The handle portion 610 is provided with a third clamping groove 611 and a fourth clamping groove 612. The third clamping groove 611 is used to clamp with the second clamping protrusion 530, and the fourth clamping groove 612 is used to clamp with the elastic clamping buckle 540.

[0107] The steps of placing the conversion handle 600 on the upper cover 500 are as follows:

[0108] First, hold the handle portion 610 of the conversion handle 600 and place the conversion handle 600 at the opening of the second installation groove 510;

[0109] Then, press the position where the handle part 610 and the elastic buckle 540 are opposite to each other, and the elastic buckle 540 will be elastically deformed under the squeezing of the handle part 610, so that the width of the second mounting groove 510 becomes larger, so that the handle part 610 can enter the second mounting groove 510 under the pressure of external force, and when the handle part 610 abuts against the bottom wall of the second mounting groove 510, the second latching protrusion 530 is latched into the third latching groove 611, and the elastic buckle 540 is latched into the fourth latching groove 612 under the action of the elastic restoring force, and the driving part 620 is latched into the second latching groove 520.

[0110] The handle mounting structure provided in this embodiment has a better effect of fixing the handle, and the risk of the handle falling off due to shaking is low. In addition, the structure is relatively simple, easy to process, and the installation and removal of the handle are also relatively convenient.

[0111] Optionally, in this embodiment, the handle portion 610 and the driving portion 620 are L-shaped. This arrangement facilitates the application of force during operation.

[0112] Optionally, the number of the second latching protrusions 530 can be multiple, such as two, three, etc., according to actual needs. This application does not make any specific limitations. Each second latching protrusion 530 corresponds to a third latching slot 611.

[0113] Further, see Fig.10 On the bottom wall of the second mounting groove 510, handle taking grooves 570 are provided on both sides of the elastic buckle 540, and the handle taking grooves 570 are located at the side openings of the second mounting groove 510. When taking the conversion handle 600, insert a finger into the handle taking groove 570, and then buckle the conversion handle 600 upward. By providing the handle taking groove 570, the difficulty of taking the conversion handle 600 is reduced.

[0114] Furthermore, if Figure 9-11 As shown, the dual power conversion switch also includes a common circuit breaker 410 and a spare circuit breaker 420 arranged on the base 100, and an upper cover 500 covering the common circuit breaker 410 and the spare circuit breaker 420. Two indication windows are provided on the upper cover 500, and the two indication windows are respectively arranged opposite to the handle of the common circuit breaker 410 and the handle of the spare circuit breaker 420, and a transparent cover plate 550 is provided at each indication window. Through the indication windows, the handle of the common circuit breaker 410 and the handle of the spare circuit breaker 420 can be observed, and then the working status of the common circuit breaker 410 and the spare circuit breaker 420 can be intuitively understood. By blocking the indication window with the transparent cover plate 550, the visualization of the indication window can be ensured, and the dustproof effect can be achieved, thereby improving the dustproof performance of the above-mentioned dual power conversion switch.

[0115] Alternatively, if Fig.14 As shown, an annular rib 560 is provided on the inner wall of the upper cover 500 at the outer edge of the indicating window. The annular rib 560 extends toward the normal circuit breaker 410 or the backup circuit breaker 420 and abuts against the normal circuit breaker 410 or the backup circuit breaker 420 .

[0116] Specifically, the annular rib 560 opposite to the common circuit breaker 410 extends toward the common circuit breaker 410 and abuts against the common circuit breaker 410, and the annular rib 560 opposite to the standby circuit breaker 420 extends toward the standby circuit breaker 420 and abuts against the standby circuit breaker 420. In this way, the annular rib 560 can play a sealing role, so that only the handle of the common circuit breaker 410 or the handle of the standby circuit breaker 420 can be observed through the transparent cover plate 550, which plays a visual aesthetic effect.

[0117] Furthermore, if Figure 15-18 As shown, the dual power conversion switch further includes a transmission mechanism 700, and the transmission mechanism 700 is used to open and close the execution switch. In a possible embodiment, the execution switch is a circuit breaker.

The sleeve 730 is sleeved on the output shaft of the rotating driving member 720. The rotating driving member 720 is used to drive the sleeve 730 to rotate. A fifth clamping groove 731 is provided at one end of the sleeve 730. A third mounting groove 741 is provided on the indicator 740. A second buckle 742 is provided on the inner wall of the third mounting groove 741. One end of the sleeve 730 provided with the fifth clamping groove 731 is inserted into the third mounting groove 741, and the second buckle 742 is clamped in the fifth clamping groove 731. The connection between the indicator 740 and the shaft sleeve 730 is achieved by snap-fitting, which reduces the number of parts and components, has a simple structure, and is convenient for installing the indicator 740.

[0119] Optionally, a plurality of second clips 742 may be provided along the circumference of the inner wall of the third mounting groove 741 , and the fifth clip groove 731 may be arranged around the shaft sleeve 730 . Such a configuration can improve the connection strength between the indicator 740 and the shaft sleeve 730 .

[0120] It is worth noting that an indicator mark is provided on the indicator member 740 , and the indicator mark is used to indicate the working state of the transmission mechanism 700 .

[0121] Optionally, in a possible embodiment, the shaft sleeve 730 is a square column structure, and the second mounting groove 510 is a square. This arrangement reduces the risk of the shaft sleeve 730 slipping in the second mounting groove 510, improves the reliability of the shaft sleeve 730 driving the indicator 740 to rotate, and further improves the reliability of the indicator 740 indicating work.

[0122] It is understandable that the rotating driving member 720 may be selected but not limited to a motor.

[0123] Further, see Figure 7 and Fig. 9 The transmission mechanism 700 further includes a drive disk 750. The shaft sleeve 730 is provided with a step surface 732. The drive disk 750 is sleeved outside the shaft sleeve 730 and abuts against the step surface 732.

[0124] Optionally, the drive disc 750 is sleeved on the outside of the shaft sleeve 730 through the square hole. This reduces the risk of slipping between the shaft sleeve 730 and the drive disc 750, improves the reliability of the shaft sleeve 730 driving the drive disc 750 to rotate, and further improves the reliability of the operation of the drive disc 750.

[0125] Further, see Fig. 9 The end of one end of the sleeve 730 having the fifth slot 731 is provided with an operating hole 733 , and the operating hole 733 is used to cooperate with the conversion handle 600 .

[0126] Optionally, in this embodiment, the operation hole 733 is a polygonal hole, and the driving part 620 of the conversion handle 600 is a polygonal cylinder. When the conversion handle 600 is manually operated, the polygonal cylinder is inserted into the polygonal hole, and then the handle part 610 of the conversion handle 600 is rotated. Such a configuration can reduce the risk of slippage between the driving part 620 and the shaft sleeve 730, and improve the reliability of the operation of the conversion handle 600.

[0127] Furthermore, if Fig.16 and Fig.19 As shown, the transmission mechanism 700 further includes a driving disk 750 and two levers 760.

The levers 760 are rotatably connected to the mounting frame 710. One end of the lever 760 is disposed between the first pressure plate 751 and the second pressure plate 752, and is matched with the limiting disk 753. The fixing of the limiting disk 753 is achieved by matching the connecting bosses 7531 and the connecting holes 754. The structure is simple and the installation is convenient.

[0128] It is worth noting that the other end of the lever 760 is used to drive the execution switch. For example, if the execution switch is a circuit breaker, the other end of the lever 760 is used to drive the handle of the circuit breaker to switch between the closing position, the opening position and the re-locking position.

[0129] Optionally, the two connecting bosses 7531 are staggered, so that the reliability of the limit plate 753 rotating with the first pressure plate 751 and the second pressure plate 752 can be improved.
