Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a double-door distribution box without a middle column. Background Technique

[0002] With the development of society, the degree of electrification is getting higher and higher, and then more and more distribution boxes appear on the road. However, due to the uncertainty of the external environment, especially in summer, the weather is changeable, often with high temperatures and short-term heavy rainfall. Heavy rainfall is likely to cause rainwater to enter the interior of the distribution box, which in turn causes a short circuit. Similarly, high-temperature weather is likely to cause the temperature inside the distribution box to be too high, resulting in the circuit being burned out. Moreover, once the distribution box cannot supply power stably, it will have a great impact on people's lives and industrial production.

[0003] In existing AC low-voltage distribution boxes, in order to meet the IP65 protection level, most distribution boxes are single-door. If the same IP65 double doors are used, a middle column needs to be added to ensure the sealing performance, but the middle column will affect the placement of internal components and cause inconvenience to operators. Another is the use environment. For example, in special narrow space requirements, using a single-door distribution box will occupy more space than a double-door one. In addition, its locking structure is single, with poor effect, and the sealing effect is not good, making it inconvenient to use. Therefore, a double-door distribution box without a middle column is needed to solve the above problems. Content of the Utility Model
