ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a fluorescent tube (1 amp), and more particularly to an end base of the fluorescent tube.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a fluorescent tube base
80
of the prior art has a seat
1
and a cover plate
91
. The seat
81
is provided with a long slot
82
and two locating tapers
83
. A conductive bridging piece
84
is disposed in the long slot
82
and provided with two springs
85
conductive to electricity so as to permit engagement of bases for use in electrically connecting two fluorescent tubes in parallel. Two conductive pieces
86
are provided at one end thereof with a locating slot
87
corresponding in location to and engageable with the taper
83
for holding the wire inserted thereinto from the seat
81
. The two conductive pieces
86
are received in the seat
81
such that the conductive pieces
86
are urged by the two springs
85
. The cover plate
91
has a hooked piece
92
which is engaged with a retaining portion
89
of the seat
81
when the cover plate
91
is joined with the seat
81
. The two conductive pieces
86
are located by the cover plate
91
.
Such a fluorescent tube base of the prior art as described above is not entirely effective in design in that it comprises two springs
85
which come in contact with the conductive bridging piece
84
and the conductive pieces
86
and are susceptible to fatigue, thereby resulting in a poor connection. In addition, the locating slot
87
of the conductive pieces
86
is structurally weak and thus incapable of locating the electric wire securely. Even though the cover plate
91
is detachable fastened with the seat
81
, the cover plate
91
can not be easily separated from the seat
81
.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a fluorescent tube base with conductive pieces which have an excellent conductive effect.
It is another objective of the present invention to provide a fluorescent tube base with a means for holding the electrical wire securely.
It is still another objective of the present invention to provide a fluorescent tube base which can be easily assembled and disassembled.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a fluorescent tube base comprising a body and a cover. The body is provided with two conductive pieces, which are connected by a conductive bridging piece and are provided with a through hole in which a connection end of the conductive pieces is securely received to ensure the conductive pieces have an excellent conductive effect. The cover is detachably fastened with the body.
The foregoing objectives, features and functions of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
