ABSTRACT:

BACKGROUND OF THE INVENTION
Referring to
FIGS. 1
to
3
, a conventional bulb assembly of a lighting string includes a connector (
1
), a holder (
2
), and a bulb (
3
). Conductive plates (
4
) are provided in the connector (
1
), such that the plates (
4
) can contact with conductive wires (
31
) of the bulb (
3
), when the bulb (
3
) and the holder (
2
) are assembled within the connector (
1
). This known conductive plate (
4
), in order to provide effective elastic contact, is designed with an elastic plate (
41
), which is folded upside-down from the conductive plate (
4
) and is inclined. As assembly, the folded portion (
42
) between the conductive plate (
4
) and the elastic plate (
41
) will be easily broken under elastic compress. When the elastic plate (
41
) is fallen, it causes ineffective electrical contact between the conductive plate (
4
) and the conductive wire (
31
) of the bulb (
3
).
