Description
Technical Field
[0001] This application relates to the field of switches, and more particularly to a switching indicator and a dual-power switch. Background Technology
[0002] A dual power switch is a device used to switch between two power sources, ensuring automatic or manual switching to a backup power source in the event of a main power failure, thus guaranteeing the continuity of power supply. It is widely used in locations with high power supply requirements, such as data centers, hospitals, factories, and communication base stations.
[0003] Existing electrical switches, such as dual-power switches, include an indicator knob. After switching between open and closed states, the indicator knob indicates the power supply status of the main power supply and the backup power supply. If the circuit breaker trips due to a short circuit or other reasons after switching between open and closed states, the circuit breaker will switch again, but the indicator knob will not change. Operators cannot visually determine the open or closed status of the switch, making it impossible to directly diagnose the fault. This results in low diagnostic efficiency and may even lead to misdiagnosis. Utility Model Content
[0004] To improve the efficiency and accuracy of judging the opening and closing status of electrical switches, this application provides an opening and closing indicator device and a dual-power switch.
[0005] This application provides a circuit breaker opening / closing indicator and a dual-power switch, which adopts the following technical solution:
[0006] A circuit breaker opening / closing indicator device includes a color block and an indicator plate. The surface of the color block facing the indicator plate is provided with a color layer. The color block is movable relative to the indicator plate. The indicator plate is a light-transmitting plate.
[0007] By adopting the above technical solution, the opening and closing indicator device can be applied to dual-power switches. The color block can move with the circuit breaker switch in the dual-power switch. For example, the color block can be directly fixed on the circuit breaker switch, or the color block can move with the circuit breaker switch through a transmission component. Since the indicator plate is a light-transmitting plate and the color block has a color layer, the user can observe the color through the indicator plate to judge the opening and closing status of the circuit breaker after the circuit breaker switches between opening and closing states. Only one color layer can be set on the color block. When the color layer is aligned with the indicator plate, the user can observe the color of the color layer through the indicator plate, indicating that the circuit breaker switch is in the closed or open state. When the color layer moves to a position where it is misaligned with the indicator plate, the user can observe the color of other structures of the circuit breaker switch through the indicator plate, indicating that the circuit breaker switch state has changed. Alternatively, two different color layers can be set on the color block, with each color layer independently aligned with the indicator plate, indicating that the circuit breaker switch is in different states. The indication results are more intuitive and can effectively improve the user's judgment efficiency and accuracy.
[0008] Optionally, a fixed bracket is also included, on which the indicator plate is mounted and the color block is slidably mounted.
[0009] By adopting the above technical solution, if the color block is fixed on the circuit breaker switch, the range of movement of the color block is large, which occupies space. However, if the color block is slidably installed on the fixed bracket, the sliding path is shorter, which saves space.
[0010] Optionally, the color block is provided with a linkage component, which includes a linkage rod on the color block and an elastic element connecting the color block and the fixed bracket. The elastic element extends and retracts along the sliding direction of the color block.
[0011] By adopting the above technical solution, the linkage component moves with the circuit breaker switch, which can adapt to the rotation generated when the circuit breaker switch is opened and closed. The elastic element ensures that the linkage rod always keeps in contact with the circuit breaker switch, resulting in good transmission effect. Moreover, the linkage rod has a simple structure and is easy to process, and the elastic element is a mature technology, which is convenient to purchase or process, thus saving production costs.
[0012] Optionally, the fixed bracket has a receiving groove on the side wall near the circuit breaker switch, and a sliding groove is provided on the inner wall of the receiving groove, and the color block is slidably disposed in the sliding groove.
[0013] By adopting the above technical solution, the slide guides and limits the sliding of the color block, and the receiving groove allows the linkage component to pass through, so that the linkage component comes into contact with the circuit breaker switch.
[0014] Optionally, one surface of the fixed bracket is a mounting surface, the receiving groove penetrates the mounting surface and is used for inserting color blocks, there is a gap between the groove sidewall and the mounting surface, and guide slopes are formed on the upper surfaces of the two opposite inner walls of the receiving groove, the distance between the two guide slopes decreases along the direction in which the color blocks are inserted into the groove.
[0015] By adopting the above technical solution, the inclined surface is set to allow the color blocks to be inserted into the groove, which facilitates assembly and saves effort.
[0016] Optionally, the color block is provided with a spring groove, the elastic element is telescopically disposed in the spring groove, the inner wall of the receiving groove is provided with a spring sleeve rod, and the elastic element is sleeved on the spring sleeve rod.
[0017] By adopting the above technical solution, the spring groove guides and limits the extension and retraction of the elastic element, and the spring sleeve guides the extension and retraction of the elastic element, making the sliding of the color block more stable.
[0018] Optionally, the spring groove extends through the sidewall of the color block toward the circuit breaker switch.
[0019] By adopting the above technical solution, the spring groove penetrates through the side wall of the color block, making it convenient to install the elastic element.
[0020] Optionally, there are two color layers, the two color layers have different colors, and the two color layers are distributed along the direction of movement of the color blocks.
[0021] By adopting the above technical solution, when the circuit breaker opening and closing indicator device is applied to electrical switches, the indicator panel corresponds to two color layers in the opening and closing states of the circuit breaker switch, respectively. When the circuit breaker opening and closing states are switched, the color blocks slide, and the different colors of the color layers are displayed through the indicator panel, making it more convenient for users to observe.
[0022] Optionally, the fixing bracket is provided with an ear plate, and the ear plate has a snap-fit groove.
[0023] By adopting the above technical solution, when the opening and closing indicator device is applied to an electrical switch, a buckle can be set on the electrical switch, and the buckle slot on the ear plate is used to connect with the buckle on the electrical switch, thereby fixing the fixed bracket on the electrical switch, which is convenient for installation.
[0024] A dual-power switch includes a housing, a circuit breaker switch disposed within the housing, and an opening / closing indicator device, wherein a display hole corresponding to the indicator plate is provided through the housing.
[0025] By adopting the above technical solution, the circuit breaker opening and closing indicator is installed inside the housing, and a display hole is provided on the housing. The display hole allows the user to observe the color of the indicator plate inside the housing to determine the opening and closing status of the circuit breaker switch, thereby determining the power supply status of the main power supply and the backup power supply, which facilitates timely maintenance of the dual power supply switch.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0038] This application discloses a circuit breaker opening / closing indicator device. (Refer to...) Figure 1 The opening and closing indicator device includes a color block 1 and an indicator plate 2. The color block 1 is plate-shaped, and the indicator plate 2 is located on the side of the color block 1 away from the circuit breaker switch 4. The color block 1 moves relative to the indicator plate 2. A color layer 3 is provided on the surface of the color block 1 facing the indicator plate 2. The indicator plate 2 is a light-transmitting plate, and the user can observe the color change through the indicator plate 2.
[0039] Reference Figure 1 and Figure 2 The opening and closing indicator device also includes a fixed bracket 5, and the indicator plate 2 is integrally formed on the fixed bracket 5, that is, the fixed bracket 5 is made entirely of transparent material. The color block 1 is slidably installed on the fixed bracket 5, and the color block 1 is provided with a linkage component 6. The color block 1 slides with the movement of the circuit breaker switch 4 through the linkage component 6. In other embodiments, the color block 1 can be fixedly installed on the circuit breaker switch 4, and the color block 1 rotates with the rotation of the circuit breaker switch 4. The color layer 3 on the color block 1 is arc-shaped.
[0040] Reference Figure 3The sliding direction of color block 1 is set to up and down. The upper surface of the fixed bracket 5 is the mounting surface 52. A receiving groove 51 is formed on the side wall of the fixed bracket 5 away from the indicator plate 2. The receiving groove 51 extends to the indicator plate 2 in the direction close to the indicator plate 2 and penetrates the mounting surface 52 of the fixed bracket 5. Color block 1 is inserted into the receiving groove 51 from the mounting surface 52. A sliding groove 511 extending vertically is formed on the two opposite inner walls of the receiving groove 51. There is a gap between the groove side wall of the sliding groove 511 and the mounting surface 52, that is, the sliding groove 511 does not penetrate the mounting surface 52. Color block 1 is slidably installed in the sliding groove 511, and the sliding groove 511 limits and guides the sliding of color block 1.
[0041] Reference Figure 3 The linkage component 6 includes a linkage rod 61 integrally formed on the side wall of the color block 1 away from the indicator plate 2, and the linkage rod 61 extends in a direction away from the indicator plate 2. A reinforcing rib 611 is integrally formed on the linkage rod 61, which helps to improve the structural strength of the linkage rod 61.
[0042] Reference Figure 2 and Figure 3 The linkage component 6 also includes an elastic element 62 pressed between the color block 1 and the fixed bracket 5. The elastic element 62 extends and retracts along the sliding direction of the color block 1. The elastic element 62 is a compression spring and is used to drive the linkage rod 61 to contact the circuit breaker switch 4. A boss 13 is integrally formed on the side wall of the color block 1 away from the indicator plate 2. A spring groove 12 is formed on the lower end surface of the boss 13. The spring groove 12 extends vertically and penetrates the side wall of the boss 13 away from the indicator plate 2. The design of the boss 13 allows the overall width of the color block 1 to be set to be smaller, and the spring groove 12 is wide enough for the elastic element 62 to press against it, thereby improving the stability of the extension and retraction of the elastic element 62 while saving production materials.
[0043] Reference Figure 3 A spring sleeve 7 is integrally formed on the lower inner wall of the receiving groove 51. The spring sleeve 7 extends vertically, and an elastic element 62 is sleeved on the spring sleeve 7. The two ends of the elastic element 62 abut against the inner wall of the receiving groove 51 and the inner wall of the spring groove 12, respectively. In other embodiments, the spring sleeve 7 may not be provided, and the spring groove 12 may not penetrate the side wall of the boss 13 away from the indicator plate 2. That is, the spring groove 12 is a countersunk hole with an open lower end face, and the elastic element 62 is telescopically disposed in the spring groove 12.
[0044] Reference Figure 2 and Figure 3There are two color layers 3 on color block 1. The two color layers 3 are distributed vertically. When the circuit breaker switch 4 is in the closed state, one color layer 3 corresponds to the indicator plate 2. When the circuit breaker switch 4 is in the open state, the other color layer 3 corresponds to the indicator plate 2. In this way, the user can judge the open and closed state of the circuit breaker switch 4 by observing the different colors shown by the indicator plate 2.
[0045] In other embodiments, only one color layer 3 may be provided, and the size of the color block 1 is the same as the size of the indicator plate 2. When the circuit breaker switch 4 is in the closed or open state, the color layer 3 on the color block 1 corresponds to the indicator plate 2. When the state of the circuit breaker switch 4 is switched, the color block 1 moves out of the projection range of the indicator plate 2 in the direction of the arrangement of the indicator plate 2 and the color block 1. At this time, what the user observes through the indicator plate 2 is the color of the installation structure of the circuit breaker switch 4.
[0046] Reference Figure 3 and Figure 4 The upper ends of the two opposing inner walls of the receiving groove 51 are chamfered to form guide slopes 512, and the distance between the two guide slopes 512 decreases along the direction in which the color block 1 is inserted into the slide groove 511. The lower two side walls of the color block 1 are chamfered to form guide slopes 11, and the inclination direction of the guide slopes 11 is consistent with the inclination direction of the guide slopes 512. The guide slopes 512 and 11 cooperate to facilitate the insertion of the color block 1 into the slide groove 511.
[0047] Reference Figure 3 The fixed bracket 5 has an ear plate 8 integrally formed on its side wall. The ear plate 8 has a buckle groove 81. The fixed bracket 5 is connected and fixed to the electrical switch through the buckle groove 81.
[0048] This application also discloses a dual-power switch, including the aforementioned open / close indicator device. (Refer to...) Figure 2 and Figure 5 and Figure 6 The dual power switch also includes a housing 9, within which a circuit breaker switch 4 is fixedly installed. A snap-fit 92 is integrally formed within the housing 9, which is used to snap-fit with the ear plate 8 on the mounting bracket 5, thereby securing the mounting bracket 5. A display hole 91 corresponding to the indicator plate 2 is provided through the housing 9, allowing the user to observe the color displayed on the indicator plate 2 through the display hole 91.
[0049] The implementation principle of the circuit breaker opening / closing indicator device in this application is as follows: When the circuit breaker switch 4 is switched to the closed state, the elastic element 62 drives the color block 1 to slide upward until the linkage rod 61 contacts the circuit breaker switch 4. At this time, one of the color layers 3 on the color block 1 corresponds to the indicator plate 2. When the circuit breaker switch 4 is switched to the open state, the circuit breaker switch 4 is pressed down, causing the linkage rod 61 to move downward, thereby causing the color block 1 to slide downward against the pressure of the elastic element 62. At this time, one of the color layers 3 on the color block 1 corresponds to the indicator plate 2. Users can judge the opening / closing status of the circuit breaker by observing the different colors shown in the indicator plate 2.
[0050] The implementation principle of a dual power switch in this application embodiment is as follows: When the main power supply is on, the circuit breaker switch 4 corresponding to the main power supply is in the closed state. At this time, the circuit breaker switch 4 corresponding to the backup power supply is in the open state, and the different color layers 3 on the two color blocks 1 corresponding to the two circuit breaker switches 4 correspond to the indicator boards 2 respectively. Conversely, when the backup power supply is on, the color layers 3 on the two color blocks 1 corresponding to the two circuit breaker switches 4 change respectively. The user can judge whether it is the main power supply or the backup power supply by observing the colors shown on the two indicator boards 2.
[0051] Since the indicator panel 2 is made of transparent material and the color block 1 has a color layer 3, after the circuit breaker is switched on and off, the user can observe the color through the indicator panel 2 to judge the circuit breaker's on and off status. The indication result is more intuitive and can effectively improve the user's judgment efficiency and accuracy.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
