Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a leakage circuit breaker. Background Art

[0002] In order to ensure the safety of electricity use, circuit breakers are widely used in smart grids. In addition to protecting load equipment from overcurrent in electrical circuits, leakage circuit breakers can also be used to protect people from electric shock and equipment from leakage. At present, most manufacturers produce leakage circuit breakers, such as patent number: CN212968303U; they need to be installed inside the electric control box when in use. When used alone, the exposed circuit breaker body and leakage module are prone to safety hazards. In particular, in rural houses, agricultural breeding greenhouses, temporary electricity use and other places, there are fewer electrical equipment, so the number of circuit breakers used is also small, usually only one or two circuit breakers are needed; however, if one or two circuit breakers are placed inside the electric control box, it is not convenient for users to use, nor is it convenient for users to hang them, and the electric control box is hung on the wall or on the pillars inside the greenhouse, which is abrupt and conspicuous, affecting the beauty of the room.

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-3 The utility model provides an embodiment: a leakage circuit breaker, comprising a circuit breaker body 1 and a leakage module 2 installed on one side of the circuit breaker body 1; the circuit breaker body 1 and the leakage module 2 are both installed on a support frame 3; the upper end surface of the support frame 3 is also provided with a wire entry hole 34, and a cover plate 37 is provided to slide with a slide groove 35 provided on the side of the wire entry hole 34, so that the cover plate 37 covers the wire entry hole 34.

[0019] In summary, the support frame 3 is used to accommodate the circuit breaker body 1 and the leakage module 2. On the one hand, the support frame 3 can be used to fix the circuit breaker body 1 and the leakage module 2 together to protect the two; on the other hand, it is convenient to install the circuit breaker body 1 and the leakage module 2 on the wall through the support frame 3;

[0020] Based on this, the circuit breaker body 1 and the leakage module 2 are fixed on the wall using a support frame 3, so that the device can be detached from the electrical control box for separate use while realizing circuit leakage detection, so that the device can be used indoors in farmhouses, in breeding greenhouses, and in places for temporary power use.

[0021] Specifically, the support frame 3 includes a back plate 30, both ends of the back plate 30 are provided with a transverse plate 36, and a side plate 33 is provided at one end of the transverse plate 36 away from the back plate 30. Therefore, when the backs of the circuit breaker body 1 and the leakage module 2 are against the back plate 30, the transverse plate 36 is located at the upper end surface and the lower end surface of the two, and the side plate 33 is used to cover the front end surface of the two, so that the support frame 3 can protect the circuit breaker body 1 and the leakage module 2 and fix the two.

[0022] Furthermore, since a guide rail 32 is provided in the middle of the back plate 30 , and the circuit breaker body 1 and the leakage module 2 are both slidably mounted on the guide rail 32 , the stability of the two after being connected to the support frame 3 can be further improved.

[0023] In addition, since a through hole 38 is also provided on the side panel 33, and is connected to the through hole 38 by a plug 5 to seal the through hole 38, when the plug 5 is removed, it is convenient for a screwdriver to connect with the screw inside the terminal to fix the wire on the device; then the plug 5 is used to cover the through hole 38 to protect the screw and prevent water vapor, dust, etc. from contacting the terminal.

[0024] On the basis of the above scheme, since one side of the support frame 3 is connected to the first baffle 6 and the other side of the support frame 3 is connected to the second baffle 7, the two baffles can be used to wrap the device from the side of the device to further protect the circuit breaker body 1 and the leakage module 2.

[0025] In addition, since the width of the support frame 3 is greater than the sum of the widths of the circuit breaker body 1 and the leakage module 2 , when the two baffles are installed, there is a movable space inside the support frame 3 to facilitate heat dissipation.

[0026] Furthermore, the support frame 3 is made of insulating material, thereby preventing the current from flowing out through the support frame 3. Meanwhile, the first baffle 6 and the second baffle 7 are both made of copper material, thereby further improving the heat dissipation capacity of the device.

[0027] In order to facilitate the installation and disassembly of the support frame 3 and the wall, the support frame 3 is connected to the fixed frame 4 through the installation groove 31, and the installation groove 31 is slidably matched with the slider 8 provided on the fixed frame 4. Based on this, the fixed frame 4 is fixed to the wall with screws and then the support frame 3 is slid along the slider 8 to achieve quick installation and disassembly of the support frame 3 and the wall.

[0028] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
