ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a Christmas lamp base, and particularly to one which includes several separable parts such that the design of the Christmas lamp base cab be easily changed by changing the design of one or more of the parts.
Referring to
FIG. 7
, a conventional Christmas lamp base includes a socket
10
and a hooked member
20
. The socket
10
has a through hole
107
on a lower part. A cord
40
is passed through the through hole for connecting the lamp to supply of electricity. The socket
10
yet has a trench
106
, through holes
102
and
103
, and a threaded portion on an inner side. The trench
106
communicates with the through hole
102
. A first conducting chip
104
is received in the trench
106
, and passed through the through hole
102
to electrically connect the cord
40
. A second conducting
105
is passed through the hole
103
to electrically connect the cord
40
. A bulb
30
is connected to the threaded portion
101
, and contact the conducting chips
104
,
105
.
The hooked member
20
projects on a lateral side of the socket
10
. The hooked member
20
has several engaging teeth
201
, a curved hanging portion
202
and several engaging protrusions
203
. The Christmas lamp can be hung on a Christmas tree, wire, on a fence from the engaging teeth
201
or the curved hanging portion
202
.
However, the lamp base in found to have disadvantages as follows.
1. The lamp base is made as a whole body without separable parts so the manufacturers have to make another mould if they want to change the design of the lamp base, ever slightly. Consequently, the manufacturing cost is relatively high.
2. When the lamp is hung on a wire from the curved hanging portion
202
, it is likely to fall off the wire because there is no stopping means at the open end of the curved portion.
SUMMARY OF THE INVENTION
Therefore, it is a main object of the present invention to provide a Christmas lamp base, which consists of several separable components. The parts can be made to have various designs, and the lamp base can be made by putting the desired parts together according to the customers' need.
It is another object of the present invention to provide a Christmas lamp base which can be hung on a Christmas tree or a wire firmly.
The lamp base of the present invention includes:
a socket; the socket having a separating plate between an upper and a lower arts thereof; the socket receiving a bulb on the upper part; the socket having a trench on a lower part provided for locating a cord; the separating plate having two connecting holes;
a hooked part; the hooked part having a connecting portion and a curved hanging potion; the connecting portion of the hooked part being connected to the socket from a lateral slot of the socket;
a bottom part, the bottom part having a bottom cover and two connecting protrusions; the bottom part being connected to the socket with the protrusions each passed through a respective one of the connecting hole of the separating plate; a first one of the connecting protrusions having two gaps engaging two engaging teeth of the connecting portion of the hooked part.
Because the parts of the lamp base are separable, the manufacturer doesn't have to make a new mould of the whole lamp base when he needs to change the design. He only has to replace one or more of the parts with others having different designs.
