Abstract (en)

[origin: US4609977A] To provide an easily made electrical connection between current leads (3, 23) extending from a halogen incandescent lamp (1, 21) through a base cup (7, 27) and connecting blades (10, 30), an attachment element (12, 32) is formed with a wall portion (12a, 32a) which, together with the bottom wall (7a) of the base cup defines a chamber, in which chamber the electrical connections between the terminal prongs (10, 30) and the current supply leads (3, 23) are formed. Openings (8) through which the current supply leads extend are sealed, for example by melting down plastic material of which the base cup (7, 27) is formed, or by pouring a resin, for example a silicone rubber resin, in the chamber (13, 33) after having made the connection, to fill the openings, seal the openings, and coat the electrical connections which, typically, are made by welding. The chamber can be entirely filled with resin, if desired.
