[0002] Cable distribution boxes often house electrical switching devices such as circuit breakers, isolating switches, and residual current devices (RCDs). Traditionally, these devices are connected using guide rails and jumper cables. This method results in complex installation and wiring procedures, exposed cables pose poor safety, and replacement requires reconnecting cables, making maintenance inconvenient. The applicant's utility model patent, "CN205901073U - Multi-circuit breaker adapter for distribution cabinets or boxes," proposes a modular installation method using a circuit breaker adapter in conjunction with busbars within the distribution box, improving safety and facilitating maintenance. During the modular installation of the circuit breaker via its adapter, the circuit breaker needs to be securely connected to the adapter, and the adapter must comprehensively consider heat dissipation and insulation to ensure the reliability and safety of the electrical connection.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , Figure 4 and Figure 5 As shown. It has a circuit breaker support surface 11, on which multiple sets of circuit breaker mounting holes 12 are arranged in pairs. The circuit breaker is connected and fixed to the circuit breaker support surface 11 through the circuit breaker mounting holes 12. The spacing between each set of circuit breaker mounting holes 12 is different. The protective cover is integrally molded from insulating material and has a relatively flat circuit breaker support surface 11 for supporting and fixing one circuit breaker 100. The electrical connection of the circuit breaker is realized inside the circuit breaker adapter base through copper busbars. After the protective cover is closed on the circuit breaker adapter base, the entire circuit breaker adapter base forms a relatively closed space, and the internal live parts such as copper busbars and terminals are not exposed. Operators will not touch the aforementioned live parts when disassembling and assembling the circuit breaker, ensuring safety. The different spacing between the sets of circuit breaker mounting holes 12 allows for the fixed installation of circuit breakers 100 of different specifications.

[0017] In a more preferred embodiment, to accommodate the installation and fixing of circuit breakers 100 of different specifications, the circuit breaker mounting holes 12 are arranged in an arc shape and set in pairs, with a different spacing between each pair of circuit breaker mounting holes 12. Specifically, as follows... Figure 1 and Figure 2 As shown, in this embodiment, three pairs of circuit breaker mounting holes 12 are arranged in an arc shape, with the spacing between each pair of mounting holes 12 gradually decreasing. The circuit breaker 100 has mounting holes 101 for fixed installation. The spacing and position of the mounting holes 101 differ for circuit breakers 100 of different specifications. Therefore, the arc-shaped arrangement of the mounting holes 12 allows for the fixed installation of circuit breakers 100 of different specifications. Alternatively, it can be done as follows... Figure 3 As shown, the circuit breaker mounting holes 12 are arranged in a straight line, and each group of circuit breaker mounting holes 12 has a different spacing to achieve adaptable installation of the circuit breaker 100. The two methods mentioned above can also be combined, depending on the specific situation. Nuts can be installed in the circuit breaker mounting holes 12, and the circuit breaker 100 can be fixedly installed from the front using bolts through the mounting holes 101 and the circuit breaker mounting holes 12.

[0018] In a more preferred embodiment, one end of the circuit breaker support surface 11 is connected to a vertically extending terminal sealing flange 13. For example... Figure 5 As shown, one end of the circuit breaker adapter has a receiving space for accommodating wiring terminals. The terminal sealing flange 13 seals the receiving space after the protective cover is closed on the circuit breaker adapter, which can prevent foreign objects from entering the circuit breaker adapter and also prevent accidental contact with internal live parts.

[0019] In a more preferred embodiment, the end of the terminal sealing flange 13 is arc-shaped. The arc-shaped sealing flange can adapt to the arc-shaped surface of the terminal receiving space, thereby achieving a tight seal of the terminal receiving space.

[0020] In a more preferred embodiment, the terminal sealing flanges 13 are spaced apart at one end of the circuit breaker support surface 11. Generally, to accommodate the three-phase connection ports of the circuit breaker, the internal copper busbars and terminals of the circuit breaker adapter are also spaced apart for three phases. Therefore, the terminal sealing flanges 13 are preferably arranged in three spaced intervals to seal the three-phase terminal receiving space.

[0021] In a more preferred embodiment, the circuit breaker support surface 11 is vertically connected to a support sidewall 14, and the support sidewall 14 opposite the terminal sealing flange 13 has a heat dissipation notch 15. Figure 4 and Figure 5As shown, after the protective cover is placed on the circuit breaker adapter base, the supporting side wall 14 can abut against the inner edge of the circuit breaker adapter base, making the circuit breaker support surface 11 of the protective cover flush with the edge of the circuit breaker adapter base. Additionally, the heat dissipation notch 15 can communicate with the internal heat dissipation channel after the protective cover is placed on the circuit breaker adapter base, providing a continuous heat dissipation channel along the internal copper busbar, thus ensuring the heat dissipation performance of the circuit breaker adapter base.

[0022] In a more preferred embodiment, the circuit breaker support surface 11 is provided with at least a pair of protruding circuit breaker support ribs 16. As in the above embodiment, the circuit breaker 100 is mounted on the circuit breaker support surface 11. If the lower surface of the circuit breaker 100 is in contact with the circuit breaker support surface 11, it will be detrimental to ventilation and heat dissipation between the lower space of the circuit breaker 100 and the circuit breaker adapter seat. The protruding circuit breaker support ribs 16 can support the circuit breaker 100 at a certain height, creating a certain gap between the lower surface of the circuit breaker 100 and the circuit breaker support surface 11. This gap enhances the ventilation and heat dissipation effect between the lower space of the circuit breaker 100 and the circuit breaker adapter seat.

[0023] In a more preferred embodiment, fixing holes 17 are provided around the circuit breaker support surface 11. Through these fixing holes 17, the protective cover can be closed and fixed onto the circuit breaker adapter base.

[0024] This embodiment also proposes a circuit breaker adapter base, including the protective cover in the above embodiment. The circuit breaker adapter base has an inlet connection hole 21, and the protective cover is fitted onto the circuit breaker adapter base. For example... Figure 5 As shown, the circuit breaker 100 is carried and installed on the protective cover. Circuit breakers 100 of different specifications can be fixedly installed through circuit breaker mounting holes 12 with different spacing.

[0025] In a more preferred embodiment, the incoming line of the circuit breaker is fixed and electrically connected to the circuit breaker adapter seat after passing through the incoming line connection hole 21 via the conductive post 22. As mentioned in the above embodiment, the circuit breaker mounting hole 12 can accommodate circuit breakers of different specifications. However, the mounting holes 101 of the circuit breaker 100 generally have two sets, upper and lower. One set can be fixed by the circuit breaker mounting hole 12 on the protective cover, while the other end is fixed by passing through the incoming line connection hole 21 via the conductive post 22. This fixes both ends of the circuit breaker 100 separately, improving the stability of the assembled circuit breaker 100. Furthermore, the incoming line connection hole 21 is preferably designed as a waist hole, with the outer two phases of the three phases being waist holes. This, combined with the various sets of circuit breaker mounting holes 12, allows for the fixed installation and electrical connection of circuit breakers 100 of different specifications.
