Abstract
A shield unit is formed such that each divided piece of a shield member, which is inserted through each slit of a shield shell and pulled out therefrom, is crimped together with a corresponding extension piece of the shield shell and crimped onto the shield shell. At that time, the outer surface of the divided piece slides on the corner at the outer edge of the slit to scrape the oxide layer off the surface of the divided piece. Each divided piece of the shield member is crimped together with each folded portion from the extension piece of the shield shell and crimped on a base of the shield shell, thereby electrically connecting the outer surface of each divided piece with the aluminum surface exposed to the base with excellent electrical conductivity.
Claims4
A shield unit, comprising:
- a cylindrical shield member having electrical conductivity;
- and
- an annular shield shell made of metal and connected to an open end of the shield member,
- the shield member comprising a plurality of divided pieces obtained by dividing the open end into multiple portions in a circumferential direction of the shield member,
- the shield shell provided with a plurality of slits into which the divided pieces are to be inserted and which are arranged, between an outer peripheral edge and an inner peripheral edge of the shield shell, at intervals in a circumferential direction of the shield shell,
- the shield shell having a plurality of extension pieces formed so as to extend from the outer peripheral edge of the shield shell, wherein
- each of the divided pieces passing through the slits is crimped together with each of the extension pieces, whereby the divided pieces are brought into pressure contact with a shield shell's portion between the outer peripheral edge and the inner peripheral edge of the shield shell.
