发明名称 Capped electric lamp
摘要 The capped electric lamp according to the invention has a lamp cap (9) of synthetic material comprising a dish-shaped part (10) having a circular-cylindrical wall portion (11) with an axis (12) and a bottom (13), and further comprising a panel (16) in which contact members (20) are anchored and a sleeve-shaped part (17) which surrounds these contact members. There is fixed in the dish-shaped part (10) a metal sleeve (7) which is telescopically joined at one end (8) with a flanged edge (6) of a metal clamping plate (5) and is connected thereto, while a seal (2) of a lamp vessel (1) is fixed in an opening of this clamping plate. The lamp is of a simple construction that can be readily manufactured and permits of fixing an electric element (3) in a pre-determined position with respect to the lamp cap (9), which requires little space in the direction of the axis (12) because a plug-in member with connection terminals can be arranged at right angles to the axis (12), while the presence of the sleeve-shaped part (17) prevents corrosion of the contact members (20).
