Description

Technical Field

[0001] This utility model relates to the field of circuit breakers, and more specifically to a high-protection signal device. Background Technology

[0002] The circuit breaker's three-position signals include the closed position signal, the open position signal, and the test position signal. These signals are indicated by specific indicator lights or display devices so that maintenance personnel can quickly and accurately determine the current status of the circuit breaker.

[0003] Closed position signal: This indicates that the circuit breaker is currently in the closed state, meaning the circuit is normally connected. In power systems, this typically means that current can flow normally through the circuit breaker, and the system is operating normally. The closed position signal is usually indicated by a green indicator light or other display device.

[0004] The trip position signal indicates that the circuit breaker is currently in the tripped state, meaning the circuit has been disconnected and current cannot flow through the circuit breaker. This typically occurs when the circuit experiences overload, short circuit, or other abnormal conditions, and the circuit breaker will automatically trip to cut off the current. The trip position signal is usually indicated by a red indicator light or other display device to alert maintenance personnel to take timely action.

[0005] Test position signal: This signal indicates the current position of the circuit breaker during maintenance, inspection, or testing. In the test position, the circuit breaker is typically isolated from the main circuit for safe maintenance and inspection operations. The test position signal is usually indicated by specific indicator lights or display devices to ensure that maintenance personnel can accurately identify the current position status of the circuit breaker.

[0006] The existing signaling device mainly consists of a pair of side plates and a connecting plate, with the connecting plate located between the two side plates. Three microswitches (closing, opening, and test) are respectively installed on the two side plates. The current signaling device has the following disadvantages in use: 1. The side plates and connecting plate are all made of iron, posing a risk of leakage under equivalent protection conditions; 2. Installation is cumbersome, as the microswitches are all fixed with screws; 3. The microswitches are easily damaged during installation, and the screws require high tightening torque; 4. Material costs are high. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] This application provides a highly protected signal device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0042] To address the technical problems of convenient assembly and low protection levels in existing signal devices, one embodiment of this application provides a highly protected signal device. This is described in detail below.

[0043] like Figures 1 to 8 As shown, a highly protected signal device includes...

[0044] Cover 1, the front end of the cover 1 has a cavity, and the rear end of the cover 1 has a cable outlet 11;

[0045] The mounting bracket is provided with three switch mounting slots. The mounting bracket is adapted to be moved from the front cavity opening into the cavity of the cover 1, and the mounting bracket is fixedly installed inside the cavity.

[0046] Three microswitches, namely the first microswitch 41, the second microswitch 42 and the third microswitch 43, are installed in three switch mounting slots respectively. During assembly, the three microswitches are moved into the housing 1 together with the mounting bracket. The button of the microswitch extends from the front side of the mounting bracket, that is, the button extends from the front end of the housing cavity. The cable connected to the terminal of the microswitch extends out from the outlet 11.

[0047] The micro switch's mounting structure, with the entire unit housed within a casing, makes it resistant to impacts.

[0048] Specifically, as an optional implementation method in this embodiment, such as Figures 3 to 8 As shown, the mounting bracket includes a left bracket 2 and a right bracket 3, which are spliced ​​together from left to right, and a first switch mounting groove is formed between the left bracket 2 and the right bracket 3, a second switch mounting groove is formed between the left bracket 2 and the cover 1, and a third switch mounting groove is formed between the right bracket 3 and the cover 1.

[0049] The first screw 61 passes through the cover 1 and connects to the left bracket 2, and the second screw 62 passes through the cover 1 and connects to the right bracket 3.

[0050] A first micro switch 41 is installed in the first switch mounting slot, a second micro switch 42 is installed in the second switch mounting slot, and a third micro switch 43 is installed in the third switch mounting slot.

[0051] The mounting bracket is assembled by splicing the left bracket 2 and the right bracket 3 together, which facilitates the assembly of the mounting bracket and the installation of the three microswitches on the mounting bracket.

[0052] Specifically, as an optional implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, the left bracket 2 is provided with a first guide post 21 and a second guide hole 22, as follows. Figure 7 and Figure 8 As shown, the right bracket 3 is provided with a second guide post 31 and a second guide hole 22;

[0053] like Figure 4 As shown, when the left support 2 and the right support 3 are spliced ​​together, the right end of the left support 2 abuts against the left end of the right support 3, the first guide post 21 passes through the second guide hole 22, and the second guide post 31 passes through the first guide hole 32.

[0054] The first screw 61 is connected to the first guide post 21, and the second screw 62 is connected to the second guide post 31.

[0055] In this embodiment, the first guide post 21 and the left support 2 are an integral structure, and the second guide post 31 and the right support 3 are also an integral structure.

[0056] like Figures 1 to 3 As shown, the assembled mounting bracket fits into the cavity of the housing 1. Before the mounting bracket is tightened by screws, the mounting bracket can move freely back and forth within the cavity with the micro switch.

[0057] like Figure 3 As shown, the first screw 61 is on the right side of the cover 1, and the second screw 62 is on the left side of the cover 1, with the screws arranged in a left-right direction.

[0058] Specifically, as an optional implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, each switch mounting slot is provided with a pair of limit pins 51, which pass through the micro switch to position the micro switch in the switch mounting slot.

[0059] The micro switch is limited on the mounting bracket by the limiting pin 51. Before the mounting bracket is assembled, the first micro switch 41 is first installed on the limiting pin 51 on the right side of the left bracket 2. Then the left bracket 2 and the right bracket 3 are spliced ​​together. At this time, the first micro switch 41 is clamped and fixed between the two brackets. The second micro switch 42 is installed on the limiting pin 51 on the left side of the left bracket 2, and the third micro switch 43 is installed on the limiting pin 51 on the right side of the right bracket 3. Then the mounting bracket is pushed into the housing 1. The second micro switch 42 and the third micro switch 43 are restricted by the housing 1 in the cavity.

[0060] As a preferred embodiment, a limiting block 52 is also provided on the left bracket 2 and the right bracket 3. The limiting block 52 cooperates with the end edge of the micro switch, which also restricts the micro switch from moving on the bracket.

[0061] Specifically, as an optional implementation method in this embodiment, such as Figures 3 to 8 As shown, a left slider 23 is provided at the lower end of the left bracket 2, and a right slider 33 is provided at the lower end of the right bracket 3;

[0062] A sliding groove 13 is provided at the bottom of the shell cavity. The left slider 23 and the right slider 33 are both located in the sliding groove 13. The left support 2 and the right support 3 are moved into the shell cavity through the left slider 23 and the right slider 3.

[0063] In this embodiment, when the left support 2 and the right support 3 are joined together, the left slider 23 and the right slider 33 also abut together, forming a single slider, as shown below. Figure 4 As shown, the mounting bracket moves within the slide groove 13 via the main slider, allowing it to be precisely moved into the cavity. At the same time, the slide groove 13 also constrains the left slider 23 and the right slider 33, preventing the mounting bracket from separating to the left and right.

[0064] Specifically, as an optional implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, a pair of mounting plates 12 are provided on the outside of the cover 1, and screw holes are provided on the mounting plates 12. The cover 1 can be fixed by the mounting screws through the screw holes on the mounting plates 12.

[0065] In this embodiment, the housing 1 is made of plastic. The plastic housing 1 reduces costs and also provides insulation.

[0066] In this embodiment, both the left support 2 and the right support 3 are integrally injection molded from plastic. (See left support 2 and right support 3 for details.) Figures 5 to 8 As shown, the limiting pin 51 and the limiting block 52 are integrally formed on the bracket.

[0067] The high-protection signal device of this utility model has an ingenious structural design. The mounting frame is spliced ​​by two left and right brackets, which facilitates the assembly of the mounting frame and the installation of three microswitches on the mounting frame. After the mounting frame is moved into the cover 1, it is locked by two screws, making the structure stable and reliable.
