The pressing plate 152 can press the fuse link 130 from the outside of the mounting hole 145. Accordingly, the fuse 130 can be held in the mounting hole 145, the position of the fuse 130 can be restricted in the horizontal direction, the fuse 130 can be prevented from being separated from the reflector 110, and the fuse 130 can be stably and reliably brought into contact with the reflector 110.

The positioning posts 146 can be inserted into the positioning holes 153 to position the pressure plate 152. With the aid of the positioning holes 153 and the positioning posts 146, during the assembly process of the pressing plate 152, the positioning holes 153 on the pressing plate 152 can be aligned with the positioning posts 146, then the pressing plate 152 is pushed to make the positioning posts 146 penetrate into the positioning holes 153, so as to realize the positioning of the pressing plate 152, and then the pressing plate 152 is fixed by the fasteners 154. This provides for efficient assembly and more accurate positioning of the pressure plate 152.

The positioning post 146 may be disposed on a side of the fuse link 130 away from the heat generating component. On one hand, the installation structure of the fuse link 130 has a larger installation space, and compared with the installation structure arranged on one side of the fuse link 130 close to the heating element, the installation structure of the fuse link 130 is not limited by the distance between the fuse link 130 and the heating element, so that the design freedom of the installation structure of the fuse link 130 is higher; on the other hand, the fuse link 130 may be disposed relatively close to the heat generating element without being limited by its mounting structure.
