Title:
SHIELDING SHEET
Document Type and Number:
Japanese Patent JP3618423
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a shielding sheet in which the contact part of a grounding terminal with a conductor layer can be formed with a simple constitution and in which the conductor layer is not stripped off when a screw is tightened by a method wherein the sheet is provided with a second opening part whose center agrees with that of a first opening part when a flap is turned down and whose area is smaller than that of the first opening part.
SOLUTION: A shielding sheet is provided with first opening parts 5 which are made in parts corresponding to grounding terminals 8 of an electronic circuit component and with second opening parts 6 whose centers agree with those of the first opening parts 5 when flaps 4 are turned clown and whose areas are smaller than those of the first opening parts 5. Thereby, when the flaps 4 are bent, the first opening parts 5 and the second opening parts 6 are overlapped in a concentric circle manner. As a result, conductor layers around opening parts (the second opening parts 6) on the side of the flaps 4 are exposed on the side of the grounding terminals 8 of the electronic circuit component through the first opening parts 5. Consequently, when screws 7 are tightened in this state, the exposed conductor layers come into contact with the grounding terminals 8.
