Abstract: A hot swap component is provided, which includes a movable portion and a fixed portion that may be electrically connected to each other by using electrical connectors. When a circuit breaker works, a pin that is of an electrical connector and that is located on the movable portion is correspondingly connected to a base located on the fixed portion, and the fixed portion and the circuit breaker inside the movable portion are conducted. When the circuit breaker is faulty and needs to be repaired and replaced, the movable portion can be pulled out from the fixed portion, and the circuit breaker is electrically disconnected from the fixed portion. An anti-electric shock protection mechanism of the fixed portion isolates a first base inside the fixed portion, thereby implementing safe hot swap of the circuit breaker.

Abstract: A foldable cabinet framework includes two side frames, a first beam body, and a second beam body, where two opposite ends of each of the first and second beam bodies are respectively connected to the two side frames. The first beam body and the second beam body each include a hinged part, and when the first beam body and the second beam body are in a straight state, the first beam body and the second beam body are supported between the two side frames, so that the two side frames are spaced apart and symmetrically disposed. The first beam body and the second beam body enclose a framework of a three-dimensional structure. The first beam body and the second beam body are folded by using the hinged part; and after the first beam body and the second beam body are folded, the two side frames are superposed with each other.
