[0003] At present, the insulating connection means between metals mostly adopts an insulating connection structure of metal plates disclosed in the announcement number CN107387516A, which realizes the connection between the two metal plates and the insulating gasket by arranging elastic clips facing each other on both sides of the center position of the insulating gasket, and opening a snap hole with the same shape as the horizontal projection of the elastic clip on the metal plate to be connected, and the length of the snap hole is smaller than the length of the horizontal projection of the elastic clip, so as to achieve the connection between the two metal plates and the insulating gasket. At the same time, the insulating gasket can isolate and insulate the two metal plates. However, a large number of splicing parts are used between the two, and many irregular-shaped structural parts are used, which not only increases the difficulty of manufacturing the assembly, but also makes the assembly operation more cumbersome, which is very easy to cause offset between the two metal parts, and it is more likely to cause loose connection and periodic contact conduction due to the offset.
