[0001] The utility model relates to the technical field of electrical equipment protection, and more particularly to a circuit breaker protective cover. Background Art

[0002] Circuit breakers are widely used in power distribution networks, high-voltage equipment, and household electrical systems. However, due to their variable working environments, circuit breakers are often exposed to high temperatures, humidity, dust, and other adverse factors, which may cause them to fail or shorten their service life. Conventional circuit breaker protective covers are cumbersome to install and cannot be quickly installed on the circuit breaker. Moreover, after installation, they lack a limiting structure, which makes them easily deviate or even detach from the circuit breaker due to environmental factors, thus failing to provide adequate protection. For example, a circuit breaker protective cover with patent publication number CN114823228A suffers from such a problem. Therefore, a circuit breaker protective cover is proposed that is easy to install and has a limiting structure to prevent the protective cover and the circuit breaker from deviating.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] The utility model provides a circuit breaker protective cover, such as Figure 1 As shown, it includes a protective cover body 1; the protective cover body 1 is provided with a protective cavity 11 with one end opening facing downward for accommodating a protective circuit breaker; two elastic clips 2 are symmetrically provided on the protective cover body 1; the two elastic clips 2 are located at the opening of the protective cavity 11; a clamping component 5 that can be used to clamp the circuit breaker terminal is provided on one end of the protective cover body 1; the two elastic clips 2 are respectively bent on one end close to the clamping component 5 to form a blocking piece 24; the clamping component 5 and the two blocking pieces 24 cooperate to form a limiting area 6 for relative limiting the protective cover body 1 and the circuit breaker; the protective cover body 1, the two elastic clips 2 and the clamping component 5 are formed as one piece.

[0027] Specifically, by prying open the elastic clip 2, the circuit breaker is placed as a whole in the protective cavity 11, thereby achieving comprehensive protection for the circuit breaker, and effectively preventing external factors such as moisture, dust, and debris from damaging the circuit breaker during use; when the protective cover body 1 is installed on the circuit breaker, the snap-on assembly 5 and the baffle 24 can be effectively snapped onto the wiring terminal of the circuit breaker, thereby achieving relative limitation between the protective cover body 1 and the circuit breaker, and effectively preventing the protective cover from accidental displacement or falling off during operation.

[0028] Optionally, mounting holes for installing the clamp are respectively opened on the two opposite surfaces of the two elastic clips 2. The operator can install the clamp through the mounting holes, making it convenient to separate the two elastic clips 2 through the clamp, further increasing the scene adaptability of the protective cover.

[0029] Furthermore, the protective cover body 1 includes: a main shell 3 and an extension shell 4; one end of the main shell 3 is detachably connected to the extension shell 4; the snap-on assembly 5 is fixedly connected to the other end of the main shell 3; the protective cover body 1 is provided with a first receiving cavity 31 with one end opening facing downward for receiving a protective circuit breaker; the extension shell 4 is provided with a second receiving cavity 41 with one end opening facing downward for expanding the protection range of the circuit breaker; the first receiving cavity 31 and the second receiving cavity 41 are connected to form the protective cavity 11.

[0030] Specifically, the provision of the second receiving cavity 41 of the extended shell 4 can further expand the protection range of the protective cover for the circuit breaker, further improving the scene adaptability of the protective cover.

[0031] Furthermore, the elastic clip 2 includes: a first clip 21 and a second clip 22; the first clip 21 and the second clip 22 are detachably connected; the first clip 21 is fixedly connected to the main shell 3 and is located at the opening of the first receiving cavity 31; the second clip 22 is fixedly connected to the expansion shell 4 and is located at the opening of the second receiving cavity 41; the first clip 21 is bent at one end close to the snap-fit ​​assembly 5 to form the baffle 24.

[0032] Furthermore, a first separation seam 12 for separating the main shell 3 and the expansion shell 4 is provided at the connection between the main shell 3 and the expansion shell 4; a second separation seam 23 for separating the first clip 21 and the second clip 22 is provided at the connection between the first clip 21 and the second clip 22.

[0033] Specifically, when the size of the circuit breaker is smaller, the main shell 3 and the extended shell 4 can be separated by the first separation slit 12 and the second separation slit 23, and the first clip 21 and the second clip 22 can be separated, so that the protection range of the protective cover is more suitable for the circuit breaker, further increasing the adaptability of the protective cover.

[0034] Furthermore, the snap-on assembly 5 includes two snap-on pieces 51; the two snap-on pieces 51 are respectively fixedly connected to the protective cover body 1; the two snap-on pieces 51 are symmetrically arranged; recessed holes 52 are provided on the surfaces of the two snap-on pieces 51 facing each other; the two recessed holes 52 cooperate to form a through hole 53 that is compatible with the wiring terminal of the circuit breaker.

The through hole 53 formed by the two recessed holes 52 can effectively match the connection terminals of most circuit breakers, thereby improving the accuracy and stability of the installation, making the connection between the protective cover and the circuit breaker more secure, and avoiding the risk of falling off.

[0036] Furthermore, a protective shell 7 is provided on the protective cover body 1; the protective shell 7 is trumpet-shaped.

[0037] Specifically, the trumpet-shaped design of the protective shell 7 can guide rainwater and dust to flow away, while increasing the flow of air, effectively cooling the temperature inside the circuit breaker, reducing electrical faults caused by water and dust accumulation, and ensuring that the protected circuit breaker remains in good working condition.

[0038] Furthermore, it also includes: a protective cover 8 for protecting and limiting the circuit breaker; the protective cover is detachably connected to the protective cover body 1.

[0039] Specifically, the protective cover 8 is made of silicone, adopts a quick-release design, and is equipped with snap connectors to facilitate users to perform regular maintenance so as to completely cover the circuit breaker and ensure that it is fully protected.

[0040] In other embodiments, the protective cover 8 can be snap-fitted onto the main housing 3 from which the expansion housing 4 is removed, thereby further improving the adaptability to different scenarios.

[0041] Furthermore, at least one force release hole 9 is provided on the protective cover body 1 .

[0042] Specifically, the force relief holes 9 are evenly distributed to ensure that a certain force relief space is provided when the protective cover is opened, thereby preventing the key parts from being broken or fractured due to deformation, and further improving the structural stability of the protective cover.

[0043] Furthermore, grooves 10 for installing three-phase indicator blocks are provided on both sides of the protective cover body 1.

It is not only impact-resistant but also lightweight and easy to install, ensuring seamless connection. The material used has good elasticity and strength.

[0046] In the first embodiment, the limiting area 6 is aligned with the connection terminal of the circuit breaker, and the two elastic clips 2 are separated using a tool, so that the circuit breaker is placed in the protective cavity 11 to protect the circuit breaker. At the same time, the blocking piece 24 and the engaging piece 51 abut against the connection terminal of the circuit breaker, so that the connection terminal of the circuit breaker is limited and placed in the limiting area 6, thereby achieving relative limitation between the protective cover body 1 and the circuit breaker, preventing the protective cover and the circuit breaker from being offset and separated due to environmental factors, resulting in failure to fully protect the circuit breaker.

[0047] In the second embodiment, if the area of ​​the first receiving cavity 31 and the second receiving cavity 41 is much larger than the circuit breaker to be protected, the main shell 3 and the extended shell 4 can be separated respectively through the first separation slit 12 and the second separation slit 23, the first clip 21 and the second clip 22 can be separated, and the second receiving cavity 41 can be moved out, thereby reducing the protection area of ​​the protection cavity 11 and making it more suitable for the size of the circuit breaker, avoiding the occurrence of poor working conditions due to excessive size; after the adjustment is completed, the limit area 6 is aligned with the connection terminal of the circuit breaker, and the two first clips 21 are separated using a tool, and the circuit breaker is placed in the first receiving cavity 31 to protect the circuit breaker. At the same time, the blocking piece 24 and the card piece 51 will abut against the connection terminal of the circuit breaker, so that the connection terminal of the circuit breaker is limited and placed in the limit area 6, thereby realizing the relative limitation of the protective cover body 1 and the circuit breaker, preventing the protective cover from being offset and separated from the circuit breaker due to environmental factors, resulting in the inability to fully protect the circuit breaker.

[0048] The utility model provides a protective cover for a circuit breaker switch. The limiting area 6 formed by the clamping component 5 and the two blocking pieces 24 can play a relative limiting role when the protective cover is installed on the circuit breaker switch, preventing the protective cover and the circuit breaker switch from being displaced or even falling off due to environmental factors such as vibration, thereby further increasing the protective effect of the protective cover; by setting the first receiving cavity 31 and the second receiving cavity 41, comprehensive protection of the circuit breaker switch is achieved, and external factors such as moisture, dust, and debris are effectively prevented from damaging the circuit breaker switch during use. The detachable design of the extended shell 4 not only expands the protection range, but also can adapt to more types and models of circuit breakers, thereby enhancing the applicability and flexibility of the product; the design of the clamping component 5 and the elastic clip 2 makes the installation process simple and easy, and can be quickly disassembled, which is convenient for users to perform maintenance and replacement operations, has an excellent user experience, and reduces the time and effort required for installation, use and maintenance.
