The upper end 3 of the sheet metal part and the lower end 4 of the sheet metal part are connected at both ends with armatures, namely armature A at one end of the sheet metal part and armature B at the other end of the sheet metal part;

[0030] The insulating cover provided in this embodiment is mainly used to cover the outer side of the sheet metal part on the electromagnetic device, such as Figure 2-3 As shown, the insulating cover includes: a groove 5 plugged into the upper end 3 of the sheet metal part in the electromagnetic device and a lap plate engaged with the lower end 4 of the sheet metal part, and the insulating cover also includes a lower baffle 6 extending along the plane where the groove 5 is located for further increasing insulation protection between the armature 10 of the sheet metal part 2 in the electromagnetic device 1, and the length of the lower baffle 6 is consistent with the length of the lap plate.

[0031] In this embodiment, the lap plate includes: an upper lap plate 7 in contact with a horizontal plane on one side of the lower end 4 of the sheet metal, and a lower lap plate 8 in contact with a horizontal plane on the other side of the lower end 4 of the sheet metal. The height between the upper lap plate 7 and the lower lap plate 8 is the thickness of the lower end 4 of the sheet metal.

[0032] The upper lap plate 7 is provided on both sides, and has holes thereon, which are aligned with the holes on both sides of the lower end 4 of the sheet metal on the electromagnetic device, and are used to install two screws 11 to connect the insulating cover to the sheet metal 2. The lower lap plate 8 is provided with a boss 9, which is inserted into the middle hole of the lower end 4 of the sheet metal for further connection.

[0033] The depth of the groove 5 is equal to the thickness of the upper end 3 of the sheet metal part. The upper end 3 of the sheet metal part is embedded in the groove 5 to achieve insulation protection of the upper end 3 of the sheet metal part.
