Title:
ELECTRIC FIELD MODERATING SHIELD OF BUSHING
Document Type and Number:
Japanese Patent JP3149790
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To securely and easily achieve an assembling work, and shield a metal material without soldering or welding and further moderate internal stress by covering on an end of a shield a recessed part of conductive rubber with a cross sectional configuration having the recessed part and not having any corner part at portions excepting the recessed part.
SOLUTION: A shield 5 comprises a shield body 51 and a shield ring 52 provided on opposite ends 51a of the shield body 51. The shield ring 52 is formed as a ring of conductive rubber having a recessed part 52a in a cross section thereof, which is adapted to cover the entire peripheries of upper and lower opposite end surfaces 51 of the cylindrical shield body 51. The shield ring 52 is adapted such that it provides a cross section not having any corner part excepting the recessed part 52a, and the width of the recessed part 52a is made smaller than the thickness of a conductor constituting the shield body 51. Hereby, the recessed part 52a can be covered on the end part 51a of the shield body 51, and hence ensures a contact with the aid of rubber resiliency that securely keeps the shield body and the shield ring 52 at the same electric potential without being easlily disengaged from them.
