[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] Reference Figure 1-2 A flame extinguishing component 1 of an electrical device, the shape of the flame extinguishing component 1 is a cuboid in a cube, an inner groove 2 is provided on one side of the flame extinguishing component 1, a flame extinguishing layer 3 is provided on the surface of the inner groove 2, the flame extinguishing layer 3 is made of flame extinguishing microcapsules wrapped with flame retardant hot melt adhesive, the capsule shell rupture temperature of the flame extinguishing microcapsules is 100-120°C, the capsule core is perfluorohexanone or inert gas, and a through hole 4 is provided on the opposite side of the opening surface of the inner groove 2. One side of the inner groove 2 of the flame extinguishing component 1 covers the cable connection of the electrical equipment, and the flame extinguishing layer 3 in the inner groove 2 can realize the safety protection of small units, and the through hole 4 is used to pass the cable.
