Description

Socket insulation assembly and manufacturing device and method thereof

Technical Field

The invention relates to the field of electric appliances, in particular to a socket insulation assembly and a manufacturing device and method thereof.

Background

The insulating core of the socket is an important part, and the ceramic core is generally adopted. Taking fig. 1 as an example, to realize insulation between the first metal part and the second metal part (insulation resistance > 500M Ω under 500V), a press-fitting manner is generally adopted to press the ferrule into the second metal part, and since the ferrule and the second metal part are tightly fitted, metal chips remain on the cylindrical surface of the ferrule after the ferrule penetrates out of the metal part 2. And the layer of metal dust generates breakdown conduction when the insulation resistance is tested. However, tight tolerances are adjusted, which ultimately results in a 38% product that is incapable of achieving insulation. Other press fitting modes can be adopted, and the two ends of the ceramic ferrule are respectively inserted into the first metal piece and the second metal piece, so that metal scraps can be prevented from being remained on the ceramic core of the insulating piece part, but the mode needs to be positioned for many times, is very complex to operate and is not suitable for batch production.
