Lamp socket for e.g. motor vehicle headlamp, has base section in region adjacent to lamp bulb and made from higher melting plastic, and lower section of plastic socket part in region of mechanical stress made from lower melting plastic

The socket has a plastic socket part (4), a base section (60) made from a higher melting plastic in a region adjacent to a lamp bulb, and a lower section (62) of a socket part made from a lower melting plastic in a region of mechanical stress. Melting points of higher and lower melting plastics are...

More Information
Summary:The socket has a plastic socket part (4), a base section (60) made from a higher melting plastic in a region adjacent to a lamp bulb, and a lower section (62) of a socket part made from a lower melting plastic in a region of mechanical stress. Melting points of higher and lower melting plastics are above and below 260 degree centigrade, respectively. A seal section (64) made from a polymer material has a seal effect. A contact-tab-sealing section (70) is provided between a contact tab (12) and the section (60) or section (62). An independent claim is also included for a method for manufacturing a lamp socket. Es wird ein Lampensockel für eine elektrische Lampe, insbesondere für eine Kraftfahrzeugscheinwerferlampe mit einem Kunststoffsockelteil, vorgesehen, das einen ersten Abschnitt aus einem höher schmelzenden Kunststoff in einem Bereich benachbart zum Lampengefäß und einen zweiten Abschnitt aus einem niedriger schmelzenden Kunststoff in einem Bereich mechanischer Beanspruchung aufweist. Auf diese Weise kann kostenintensiver höher schmelzender Kunststoff eingespart werden, während gleichzeitig im Bereich mechanischer Beanspruchung eine höhere Lebensdauer abgesichert werden kann.
