Description

Technical Field

[0001] The utility model belongs to the technical field of charging pile component installation, and relates to a molded case circuit breaker installation bracket. Background Art

[0002] In the current construction of electric vehicle charging infrastructure, charging piles are core equipment, and their stability and safety are crucial. Molded case circuit breakers, as essential electrical protection components within charging piles, are responsible for disconnecting the circuit in abnormal situations such as short circuits and overloads, effectively preventing electrical fires and equipment damage. While the traditional installation method, which involves screwing screws through the mounting holes of the molded case circuit breaker and securing them with rivet nuts on the mounting plate, meets basic installation requirements to a certain extent, it presents a series of practical problems, particularly when dealing with molded case circuit breakers of varying weights.

[0003] Small molded case circuit breakers (MCCBs) are relatively easy to install due to their compact size and light weight. Installers can easily support the bottom of the breaker with one hand while tightening the screws with a screwdriver or other tool, resulting in high overall installation efficiency. However, the situation is quite different when it comes to medium-sized or larger MCCBs. These breakers are often heavy and difficult to hold steadily with one hand, which not only increases the installation difficulty but also requires the coordinated efforts of at least two engineers. One engineer is responsible for holding the breaker while another is responsible for tightening the screws. This collaborative approach is not only inefficient but can also easily cause the breaker to slip, resulting in equipment damage or even injury, posing a safety hazard at the installation site if coordination is poor. Furthermore, traditional installation methods lack the necessary stoppers between the MCCB and the mounting bracket, making it prone to vertical and horizontal movement during installation, making it difficult to precisely align the mounting holes. This not only increases installation time and complexity, but can also affect the proper function of the breaker due to insecure installation, reducing the stability and reliability of the entire charging station system. More seriously, heavy molded case circuit breakers cannot be safely and reliably installed by a single person, requiring a collaborative effort of two people, which undoubtedly increases labor and time costs. Given the current scale of charging pile construction and the growing demand for installation, this inefficient and costly installation method is clearly no longer suitable for the needs of industry development. A more efficient, safe, and economical installation solution is urgently needed.

[0004] In summary, the problems with the existing MCCB installation method not only affect the installation efficiency and safety of charging piles, but also increase construction and operation costs, limiting the rapid deployment and optimization and upgrading of electric vehicle charging infrastructure. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem that the molded case circuit breaker bracket in the prior art cannot meet the requirement that the molded case circuit breaker can be installed by one person and has unlimited positions, and to provide a molded case circuit breaker mounting bracket.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] In a first aspect, the utility model provides a molded case circuit breaker mounting bracket, comprising a molded case circuit breaker mounting bracket, wherein both sides of the molded case circuit breaker mounting bracket are fixedly connected to limit plates, and the distance between the limit plates on both sides matches the installation size of the molded case circuit breaker; the bottom of the molded case circuit breaker mounting bracket is fixedly connected to a support plate.

[0008] Further improvements are:

[0009] The length of the support plate extending out of the mounting surface of the molded case circuit breaker mounting bracket is greater than 2 / 3 of the thickness of the molded case circuit breaker.

[0010] The limiting plate and the supporting plate are made of metal.

[0011] The limiting plate is a sheet metal part; the limiting plate includes a first bending limiting edge and a second bending limiting edge.

[0012] The first bending limiting edge and the second bending limiting edge are both provided with arc-shaped bends.

[0013] The arc-shaped bent convex surfaces are arranged opposite to each other; and the distance between the convex surfaces is smaller than the installation size of the molded case circuit breaker.

[0014] The molded case circuit breaker mounting bracket is provided with screw holes for mounting the molded case circuit breaker; the limiting plate and the supporting plate are arranged opposite to the screw holes so that the mounting holes on the molded case circuit breaker are aligned with the screw holes.

[0015] The support plate is a bottom limiting edge, and the bottom limiting edge is a sheet metal part.

[0016] The length of the bottom limiting edge extending out of the mounting surface of the molded case circuit breaker mounting bracket is greater than the mounting thickness of the molded case circuit breaker, and the end of the bottom limiting edge is bent upward.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model discloses a molded case circuit breaker mounting bracket. By fixing limit plates on both sides of the molded case circuit breaker mounting bracket, the installation position of the molded case circuit breaker can be accurately defined, effectively preventing the circuit breaker from shifting or shaking during the installation process, thereby enhancing the stability and reliability of the installation. The presence of the limit plates provides clear installation instructions for the installer, making the installation process more intuitive and simple, and reducing the installation difficulty and time cost. The support plate fixedly connected to the bottom of the molded case circuit breaker mounting bracket not only provides additional support for the entire mounting bracket, but also enhances its anti-overturning ability, ensuring that it remains stable during long-term use. The stable installation and support structure helps to reduce safety hazards caused by improper installation or long-term use, such as the circuit breaker falling off or loosening, thereby improving the overall safety of the electrical system. The provision of the support plate allows a single person to complete the installation and fixation, saving manpower.

[0019] Furthermore, by using sheet metal as the limit plate, not only the strength and durability of the limit plate are guaranteed, but also the limit plate can more accurately control the installation position of the molded case circuit breaker. The design of the first bent limit edge and the second bent limit edge further enhances the limiting effect and effectively prevents the circuit breaker from shifting or shaking during installation and use. The setting of the arc-shaped bend makes it easier for the limit plate to be clamped into the two sides of the molded case circuit breaker during installation, reducing the difficulty of installation. At the same time, the convex surfaces of the arc-shaped bend are arranged relative to each other, and the distance between the convex surfaces is smaller than the installation size of the molded case circuit breaker. This design ensures that the circuit breaker can be firmly clamped during installation without the need for additional fixing measures, thereby improving the convenience of installation. The arc-shaped bend design on the limit plate not only enhances the limiting effect, but also enables the mounting bracket to be applicable to more different specifications and models of molded case circuit breakers. This design improves the versatility and applicability of the mounting bracket and reduces the cost and time of replacing mounting brackets of different specifications.
