an annular side wall (11) for surrounding those elements (25) of a circuit that have to be shielded against electromagnetic radiation, said side wall (11) defining a bottom and a ceiling opening (15), and
a cover (12) for closing the ceiling opening (15),
wherein
said annular side wall (11) and said cover (12) are defined as parts of an integral cap (23) by a predetermined breaking line (26),
characterized, in that
said predetermined breaking line (26) is formed by two parallel notches (21) andor perforations (29) to define a tear open strap (31).
11. Shielding element as claimed in claim 10, characterized in that said two parallel notches (21) are both formed in one surface of said cap (23).
12. Shielding element as claimed in claim 11, characterized in that said cover (12) is provided with an engaging element (27, 34), for being engaged by a tear open tool.
13. Shielding element as claimed in claim 11, characterized in that said engaging element is formed by a hole (27) for insert of a tear open tool.
14. Shielding element as claimed in claim 11, characterized in that said engaging element is formed by a tongue (34) defined by said predetermined breaking line or lines (26, 26\u2032).
15. Shielding element as claimed in claim 13, characterized in that said predetermined breaking line (26) is provided in a side wall portion (11) adjacent to an upper edge thereof.
16. Shielding element as claimed in claim 14, characterized in that said predetermined breaking line (26) is provided in cover (12) portion adjacent to its peripheral edge.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A torque socket, comprising:
a shaft rod, one end thereof being axially formed with an insertion tenon having a non-round cross section, the other end being axially extended with a core shaft formed with at least a cut groove transversally on a surface and radially and protrudingly formed with a flange part; and
a shaft cylinder, two axial ends thereof being respectively formed with a shaft slot having a round cross section and a sleeve slot having a non-round cross section, wherein said shaft slot being a stepped hole having the dimension slightly smaller than said core shaft and allowing said core shaft to be inserted therein, said shaft slot being formed with a buckle part corresponding to the location of said flange part for buckling said flange part, and the interior of said shaft slot being radially and protrudingly formed with a friction segment for tightening said core shaft, thereby forming a preset torque value between said core shaft and said shaft slot.
2. The torque socket as claimed in claim 1, wherein a magnet is disposed in said sleeve slot.
3. The torque socket as claimed in claim 1, wherein said core shaft is axially formed with a rod hole in communication with a cut groove, and lubrication oil is provided in said rod hole.
4. The torque socket as claimed in claim 1, wherein said core shaft is formed with an oil storage zone at the periphery of each cut groove.
5. The torque socket as claimed in claim 1, wherein a free end of said insertion tenon of said core shaft is formed with a chamfer part, a guide surface is formed at the inlet periphery of said sleeve slot.
