CAPPED ELECTRIC LAMP AND LOW-PRESSURE MERCURY-VAPOR DISCHARGE LAMP

摘要

A capped electric lamp comprises a cap which is secured to a light-transmitting lamp vessel having an electric element, which lamp cap is provided with a projecting contact pin (4) having an axis (11). An electric conductor (5) is connected to the electric element and the contact pin (4). The contact pin (4) is unilaterally deformed in an inward direction so as to form an indentation (15) for fixing the electric conductor (5). According to the invention, the electric conductor (5) in the contact pin (4) does not extend substantially beyond a boundary (16) of the indentation (15). Preferably, the indentation (15) has a pinch portion (17) for weakening the electric conductor during the deformation of the contact pin (4). Said pinch portion (17) preferably deepens at an angle alpha with respect to the axis (11), wherein 25 DEG ≤ alpha ≤ 45 DEG . In addition, the indentation (15) has a press portion (18) for fixing the electric conductor (5) in the contact pin (4).
