Description

Technical Field

[0001] This utility model relates to a circuit breaker component, specifically a modular circuit breaker cover. Background Technology

[0002] Circuit breakers, as indispensable protective devices in power systems, play a crucial role in their function and effectiveness. They can quickly and automatically disconnect the circuit when abnormal conditions such as short circuits, overloads, or undervoltage occur, effectively preventing dangerous situations such as fires caused by excessive current. Circuit breakers also have overload protection functions; when the current in the circuit exceeds a set value, they can promptly cut off the power supply to prevent equipment damage due to overheating. Furthermore, with technological advancements, circuit breakers have incorporated leakage current protection, further enhancing electrical safety. In practical applications, circuit breakers demonstrate high reliability and stability, providing strong support for the safe and stable operation of power systems. When using circuit breakers, a protective cover is installed on the outside of the circuit breaker, with a cover plate on top.

[0003] In the prior art, document number 202021879198.2 describes a cover plate and a circuit breaker. This utility model relates to the field of circuit breaker technology and includes a cover plate and a circuit breaker. The cover plate body has through holes, and a connector is fixedly provided around each through hole on the side of the cover plate body covering the circuit breaker. A recess is formed in the opposite direction of the connector on the side of the cover plate body where the connector is located. The through holes and recesses can be correspondingly connected to a boss directly above a wiring screw on the cover plate surface of the circuit breaker, and the connector can be correspondingly connected to a groove on the cover plate surface of the circuit breaker. In this utility model, the corresponding connection between the through holes and recesses and the boss, and the corresponding connection between the connector and the groove, ensures that the cover plate fully covers the surface of the circuit breaker.

[0004] While existing technologies can ensure a good product appearance, they can also effectively prevent the internal structure of the circuit breaker from being deformed by external forces, thus affecting its performance. However, when it is necessary to assemble the cover plate and the circuit breaker housing, the assembly and disassembly are inconvenient. Utility Model Content

[0005] To overcome the shortcomings of existing technologies in terms of efficient assembly and disassembly, this utility model provides a modular circuit breaker cover.

[0006] This utility model is achieved using the following technical solution: a modular circuit breaker cover plate, comprising a cover plate divided into a first cover plate and a second cover plate, with a side upright plate between the first and second cover plates. A circular hole is provided on the side upright plate. Threaded holes communicating with the circular hole are provided on both the first and second cover plates. A threaded rod is fitted into the threaded hole. A bottom mounting plate is provided at the bottom of the second cover plate. A pin is provided on the bottom mounting plate. An adapter groove is provided on the bottom mounting plate. A pin is fitted into the adapter groove. One side of the pin has an external thread, and the pin is assembled and connected using the external thread.

[0007] The top of the second cover plate is provided with a heat dissipation component, which is a heat dissipation groove, and the heat dissipation groove is symmetrically distributed on the second cover plate.

[0008] The first cover plate is provided with a groove, and a moisture-absorbing module is provided in the groove. The moisture-absorbing module is adhered to the top of the groove by an adhesive part.

[0009] The groove is provided with a cover plate with a round hole on the outside. The moisture absorption module is a composite moisture absorption material filling module. The second cover plate is provided with a front side plate and a rear side plate on both sides.

[0010] Compared to existing technologies, the cover plate of this utility model is divided into a No. 1 cover plate and a No. 2 cover plate. This segmented design makes the cover plate more convenient in production, transportation and installation. The No. 1 cover plate and the No. 2 cover plate can be produced and processed separately according to actual needs, which allows the circuit breaker cover plate to be modularized. This facilitates later assembly and maintenance. When the circuit breaker needs maintenance or repair, each cover plate module can be easily disassembled and installed without operating the entire cover plate, thus improving work efficiency.

[0011] The round holes on the side uprights and the threaded holes on the No. 1 and No. 2 cover plates that are interconnected with the round holes provide a positioning and stable connection method for the cover plates. The engagement of the threaded rod with these threaded holes ensures that the connection between the No. 1 and No. 2 cover plates is tight and reliable, effectively preventing the cover plates from loosening or shifting during the operation of the circuit breaker.

[0012] The bottom mounting plate at the bottom of the second cover plate is equipped with a pin and an adapter slot. The pin is assembled and connected by external thread, which increases the connection strength between the cover plates and makes the assembly process simpler and faster. During installation, only the pin and the circuit breaker need to be assembled, which allows the cover plate and the box to be effectively assembled. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] A modular circuit breaker cover plate is provided, comprising a cover plate 1 and a cover plate 2. A side upright plate 3 is provided between the cover plate 1 and the cover plate 2. The side upright plate 3 has a circular hole. The cover plate 1 and the cover plate 2 have threaded holes that communicate with the circular hole. A threaded rod 4 is installed in the threaded hole. A bottom mounting plate 5 is provided at the bottom of the cover plate 2. A pin 6 is provided on the bottom mounting plate 5. An adapter groove 7 is provided on the bottom mounting plate 5. The pin 6 is installed in the adapter groove 7. One side of the pin 6 has an external thread. The pin 6 is assembled and connected by the external thread.

[0020] The cover plate is divided into cover plate 1 and cover plate 2. This segmented design makes the production, transportation and installation of the cover plate more convenient. Cover plate 1 and cover plate 2 can be produced and processed separately according to actual needs, which allows the circuit breaker cover plate to be modularized. This facilitates later assembly and maintenance. When the circuit breaker needs maintenance or repair, each cover plate module can be easily disassembled and installed without operating the entire cover plate, thus improving work efficiency.

[0021] The round holes on the side upright plate 3 and the threaded holes on the No. 1 cover plate 1 and the No. 2 cover plate 2 that are connected to the round holes provide a positioning and stable connection method for the cover plates. Through the cooperation of the threaded rod 4 with these threaded holes, it can ensure that the connection between the No. 1 cover plate 1 and the No. 2 cover plate 2 is tight and reliable, effectively preventing the cover plates from loosening or shifting during the operation of the circuit breaker.

[0022] The bottom mounting plate 5 at the bottom of the second cover plate 2 is provided with a pin 6 and an adapter groove 7. The pin 6 is assembled and connected by external thread, which increases the connection strength between the cover plates and makes the assembly process simpler and faster. During installation, only the pin 6 and the circuit breaker need to be assembled, so that the cover plate and the box can be effectively assembled.

[0023] The top of the second cover plate 2 is provided with a heat dissipation component, which is a heat dissipation groove 8. The heat dissipation groove 8 is symmetrically distributed on the second cover plate 2. The first cover plate 1 is provided with a groove, and a moisture absorption module 10 is provided in the groove. The moisture absorption module 10 is adhered to the top of the groove 9 by an adhesive part. The heat dissipation component at the top of the second cover plate 2 is a heat dissipation groove 8. The heat dissipation groove 8 can increase the heat dissipation area of ​​the cover plate and effectively improve the heat dissipation efficiency. When the circuit breaker is working, the heat generated can be quickly dissipated through the heat dissipation groove 8, avoiding heat accumulation inside the cover plate, thereby ensuring the normal operating temperature of the circuit breaker and extending its service life.

[0024] A groove 9 is provided on the first cover plate 1, and a moisture-absorbing module 10 is installed in the groove. The moisture-absorbing module is adhered to the top of the groove 9 by an adhesive part. A cover plate with a round hole is provided on the outside of the groove 9. The moisture-absorbing module 10 is a composite moisture-absorbing material filling module. The second cover plate 2 has a front side plate 11 and a rear side plate 12 on both sides, which can effectively absorb moisture from inside and outside the cover plate. In a humid environment, moisture easily condenses inside the cover plate, which leads to a decrease in the insulation performance of electrical equipment and even causes faults such as short circuits. Through the adsorption effect of the moisture-absorbing module 10, a dry environment can be maintained inside the cover plate, improving the operational safety of the circuit breaker.

[0025] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
