Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes or distribution boxes, and particularly relates to an adapter box applied to narrow spaces. Background Art

[0002] A generator set is a common power equipment. Due to different powers and usage environments, there are obvious differences in its external dimensions. The external dimensions of the adapter box used in conjunction with the generator set also change accordingly. Especially for the adapter box located inside the generator set cabin, restricted by space and total weight requirements, its size and structure need to be as concise as possible. At the same time, the position left for the adapter box is very narrow, which is not conducive to maintenance.

[0003] The patent with the application number "202311377010.2" discloses "a cable adapter box", which includes a box body and a box door. A plurality of through holes are opened at the bottom of the box door, and the cable passes through the through holes to the top inside the box body; in the cable adapter box of the present invention, the end of the cable is installed inside the box body. One is to protect the cable joint, protect the cable therein, prevent it from being squeezed and collided by foreign objects from the outside, and at the same time isolate the outside wind, sun and rain, reduce the possibility of moisture absorption, and thus reduce the occurrence of accidents easily caused by the breakdown of the cable middle head. However, when repairing or installing internal components, the box body needs to open the cabin door outwards. When the space inside the generator set where it is installed is small, it will cause the problem that the cabin door cannot be opened.

[0004] Therefore, our company proposes an adapter box applied to narrow spaces. Summary of the Invention

[0005] The purpose of the utility model is to provide an adapter box applied to narrow spaces, which can be applicable to the narrow space inside the generator set and is convenient for later maintenance.
