Abstract: The present invention Provides a discharge tube connector which suppresses the occurrence of a damage of a discharge tube at the time of installation and can be easily installed. An end electrode of the discharge tube and a board electrode on a circuit board can be electrically connected with each other through a conductive connection portion without using lead wires, so a damage such as a crack and the like, of a light-emitting portion of the discharge tube can be avoided. When a holding portion is made of a rubber-like elastic material, the conductive connection portion has rubber-like elasticity, so the conductive connection portion can be pressed between the end electrode and the board electrode on the circuit board to conductively connect the end electrode with the board electrode. Therefore, the soldering operation can be omitted. Thus, installation does not take time, so a manufacturing cost can be reduced.

Abstract: A stress-balancing layer formed over portions of a spring metal finger that remain attached to an underlying substrate to counter internal stresses inherently formed in the spring metal finger. The (e.g., positive) internal stress of the spring metal causes the claw (tip) of the spring metal finger to bend away from the substrate when an underlying release material is removed. The stress-balancing pad is formed on an anchor portion of the spring metal finger, and includes an opposite (e.g., negative) internal stress that counters the positive stress of the spring metal finger. A stress-balancing layer is either initially formed over the entire spring metal finger and then partially removed (etched) from the claw portion, or selectively deposited only on the anchor portion of the spring metal finger. An interposing etch stop layer is used when the same material composition is used to form both the spring metal and stress-balancing layers.

Abstract: The lamp has a lamp cap (10) with a metal shell (20), in which an insulator body (30) with a circumferential outer surface (31) between a first and a second end face (32, 33) is locked. Recesses (34) occur at the outer surface (31) at a cross-section (II--II). Between these recesses (34) the outer surface (31) has flattened portions (35), which enable the metal shell (20) to be deformed when the insulator body (30) and the shell (20) are assembled together, and to widen temporarily near the recesses (34). As a result projections (23) in the metal shell (20) can be depressed more deeply than in the case of an outer surface (31) without flattened portions (35). Consequently, the projections (23) press clampingly in the recesses (34) of the outer surface (31), when the metal shell (20) is released, thereby tightly securing the insulator body (30) in the metal shell (20 ).
