Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a photovoltaic power distribution circuit breaker. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of three parts: solar panels (modules), controllers, and inverters, with the main components being electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, this forms a photovoltaic power generation device. When distributing the generated electricity, circuit breakers are required to protect the power lines and motors.

[0003] Most existing circuit breakers are equipped with a dustproof housing, which consists of two parts: one part is used to fix the circuit breaker, and the other part is used to extend the circuit breaker switch to protect the rest of the circuit breaker. However, in the existing structure, these two parts are usually connected by multiple screws. When the circuit breaker needs to be inspected, multiple screws need to be unscrewed one by one, which is inconvenient. Utility Model Content

[0040] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Given that most existing circuit breakers are equipped with dustproof housings, which are divided into two parts—one part for fixing the circuit breaker and the other part for extending the circuit breaker switch to protect the rest of the circuit breaker—in the existing structure, these two parts are generally connected by multiple screws. When the circuit breaker needs to be inspected, multiple screws need to be unscrewed one by one, which is quite inconvenient.

[0043] like Figure 1-6 As shown, this utility model embodiment provides a photovoltaic power distribution circuit breaker, including: a circuit breaker 2 installed inside a first housing 1; a second housing 3 installed on one side of the first housing 1, and a cover 4 rotatably connected to one side of the second housing 3; the second housing 3 and the first housing 1 are connected by a mounting assembly 5, the mounting assembly 5 including: a frame 51 fixedly connected to one side of the first housing 1; a plate 52 fixedly connected to the bottom of one side of the frame 51, and a groove 521 that mates with the frame 51 and the plate 52 is opened on one side of the second housing 3; a slider 53 is provided. Inside the second housing 3, the slider 53 is inserted into the first slot 531 at the top of the plate 52; the guide rod 54 is slidably connected to both sides of the slider 53, and a spring 541 is sleeved on the outside of the guide rod 54; the insert block 55 is fixedly connected to one side of the cover 4, and the insert block 55 is inserted into the second slot 551 on one side of the slider 53; the screw 56 is threadedly connected to one side of the cover 4; the column 57 is fixedly connected to one side of the second housing 3, and the screw 56 passes through the cover 4 and is threadedly connected to the inside of the column 57, thus fastening the second housing 3 and the cover 4 together.

[0044] In use, first screw the circuit breaker 2 into the inside of housing 1 using screws. Then, align the groove on housing 3 with the switch of the circuit breaker 2 and move it towards the circuit breaker 2 until housing 3 is flush against one side of housing 1. Next, install housing 3 on one side of housing 1. Then, rotate the cover 4 to cover the surface of housing 3 and secure it to the surface of housing 3 using screws or hooks. Because housing 3 has square-like protrusions inside surrounding the switch of the circuit breaker 2, the surface of these protrusions... A sealing gasket is also provided. The sealing gasket is made of rubber material and can deform under external pressure. When the cover 4 is placed on the second housing 3, the protrusion can just contact one side of the second housing 3, so the sealing gasket will protrude on the surface of the protrusion. When the cover 4 is closed, the sealing gasket will be compressed and deformed, which will enhance the sealing between the cover 4 and the second housing 3, thereby protecting the circuit breaker 2. (The groove on the second housing 3, the fixing method of the cover 4, the protrusion and the sealing gasket are all existing technologies and are not shown in the figure. They will not be described in detail here.)

[0045] When installing the second housing 3, first align the groove 521 on one side of the second housing 3 with the plate 52 and the frame 51. Then push the second housing 3 toward the first housing 1, so that the plate 52 and the frame 51 are inserted into the groove 521. During the process of pushing the second housing 3, one side of the slider 53 will be pressed and pushed upward by the edge of the plate 52, causing the slider 53 to slide upward along the guide rod 54 and compress the spring 541. When the first slot 531 is pushed below the slider 53, the slider 53 will be pushed by the compressed spring 541 and inserted into the first slot 531, thus limiting the second housing 3. Then rotate the cover 4 so that the cover 4 covers one side of the second housing 3. At this time, the insert block 55 will be inserted into the second slot. In step 551, the slider 53 is initially positioned, and then the screw 56 is screwed into the column 57 to further secure the cover 4. At the same time, by positioning the cover 4, the insert block 55 is always inserted into the second slot 551 when the cover 4 is closed, thus preventing the second housing 3 from falling off the first housing 1 when the cover is closed. When the circuit breaker 2 needs to be repaired and the second housing 3 needs to be disassembled, first unscrew the screw 56 from the inside of the column 57, then open the cover 4 and lift the slider 53 upwards to move the slider 53 out of the inside of the first slot 531, so that the connection between the plate 52 and the second housing 3 can be made, thus making it easy to remove the second housing 3 from one side of the first housing 1.

[0046] Furthermore, a protective component 6 is provided on the first housing 1 to prevent water from entering the interior of the first housing 1. The protective component 6 includes: a threaded seat 61 fixedly installed on the top and bottom of the first housing 1; a threaded cover 62 threadedly connected to the outside of the threaded seat 61; and a sealing ring 63 fixedly connected to the inside of the threaded cover 62, with the wire connected to the circuit breaker 2 passing through the inside of the sealing ring 63 and fitting against the inner wall of the sealing ring 63.

[0047] In use, first connect one end of the wire to the terminal of the circuit breaker 2, then pass the other end of the wire through the through hole at the top or bottom of the first housing 1. Then, select a threaded cap 62 with a suitable inner diameter (the inner diameter is slightly smaller than the outer diameter of the wire, so that the threaded cap 62 can slide against the outside of the wire with resistance under the action of the sealing ring 63) according to the diameter of the wire. Insert the threaded cap 62 into one end of the wire and screw the threaded cap 62 onto the external thread of the threaded seat 61. The sealing ring 63, which is in close contact with the outside of the wire, can protect the first housing 1 and further achieve the dustproof effect.

[0048] Furthermore, the threaded seat 61, the threaded cover 62, and the sealing ring 63 are a group, and multiple groups are provided on the first housing 1. The number of groups is the same as the number of wires connected to the circuit breaker 2, which facilitates dust prevention at each terminal of the circuit breaker 2.

[0049] Furthermore, a first lock head 31 is fixedly connected to one side of the second housing 3, and a second lock head 41 is fixedly connected to one side of the cover 4. When the cover 4 is placed on the second housing 3, the second lock head 41 is located directly below the first lock head 31. This makes it easy to lock the first lock head 31 and the second lock head 41 together when the cover 4 is placed on the second housing 3, thereby enhancing the security of the second housing 3. Also, since the slider 53 is stuck inside the second housing 3 by the insert block 55, it is not easy to push the slider 53 from the outside of the second housing 3, thus making it difficult to remove the second housing 3 from the first housing 1 (except for forced removal).

[0050] Furthermore, a locking block 511 is fixedly connected to the top of one side of the frame 51, and a slot 512 that cooperates with the locking block 511 is opened on one side of the second housing 3. This facilitates the upper part of the second housing 3 to be limited by the locking block 511 and the slot 512 when the second housing 3 is installed, so as to prevent the upper part of the second housing 3 from falling off the first housing 1 during use. When removing the second housing 3, it is necessary to increase the pulling force of the second housing 3 to remove it from the locking block 511.

[0051] Furthermore, the bottom of the slider 53 extends to the outside of the second housing 3, and the protruding part is provided with a slope. The first slot 531 cooperates with the protruding part of the bottom of the slider 53, so that when the second housing 3 is pushed towards the first housing 1, the edge of the plate 52 presses the slope of the protruding part of the slider 53, thereby pushing the slider 53 upward, thus facilitating the installation of the second housing 3.

[0052] Furthermore, the distance that the top of the slider 53 can slide upward is greater than the height of the bottom protrusion of the slider 53, which makes it easier to pull the slider 53 upward, thereby pulling the bottom protrusion of the slider 53 out of the first slot 531, and thus releasing the installation of the first housing 1 and the second housing 3.

[0053] Furthermore, the height of the second slot 551 is greater than the height of the insert 55, which makes it easier to insert the insert 55 into the second slot 551 when rotating the cover 4.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
