ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a set of fancy-lamp bulb and socket adapter, and more particularly to a set of fancy-lamp bulb and socket adapter without conventional fixed sleeve.
2. Description of Prior Art
In accordance with the conventional fancy-lamp bulb and socket adapter (as shown on FIG.
6
), a fixed sleeve
52
is put on the bottom of the Christmas-lamp bulb for retaining the bulb and fixing the cords
53
leading out from the two electrodes of the bulb
51
by stretching out the cords
53
and banding back, then plug the assembly of the bulb
51
and the fixed sleeve
52
into the socket adapter
54
so that the fixed sleeve
52
fit into the socket adapter
54
tightly, and simultaneously the cords
53
leading out from the two electrodes of the bulb
51
contact with the conductors (not shown) at inside of the socket adapter
54
.
In this mechanism, the fixed sleeve
52
is used for stiffening the long stem Christmas-lamp bulb
51
, and keeping the smooth contact between the cords
53
of the terminals of bulb
51
and the conductors of the socket adapter
54
.
On the other regard, the fixed sleeve
52
can enhance the water proof function between the bulb
51
and the socket adapter
54
so as to prevent the water from entering in and piling up in the inside of the socket adapter
54
to bring up short circuit between the both terminals.
If the joint between the bulb and the socket adapter has sealing and locating functions, and the conductors is kept in steady contact with the cords at the bulb bottom, the fixed sleeve can be omitted so as to save component and assembling cost.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore a main object of the present invention to provide a set of fancy lamp bulb and socket adapter without fixed sleeve, and simultaneously have well waterproof and locating functions, and steady conduction contact between the fancy-lamp bulb and the socket adapter.
This object is achieved by a set of fancy-lamp bulb and socket adapter, in which the bulb has a flat edge at the bottom side, and extends a sealing lug from the center of the bottom to downward, and a terminal portion is extended from the sealing block bottom, and two electrodes cover on the both end of the terminal portion separately; the socket adapter has a sealing socket at the neck portion, and a key embedding groove grooved on the bottom of the sealing socket; the conducting strip has a sharp bottom, and an elastic clamping upper portion for locating in the locating hole of the key groove; by means of touching surfaces of the sealing lug at the bottom of the bulb, top surface and the sealing socket and the bottom surface of the sealing socket of the socket adapter, the lapping surfaces appear into horizontal and vertical three dimensions change to form a solid sealing structure.
If water would permeate into the inside of the socket adapter, first it will be blocked by the couple of touching surfaces of the bottom side of the bulb and the top rim surface of the socket adapter horizontally, then it will meet the block coming from the vertical touching surfaces between the sealing lug and the sealing socket, so the sealing effect of this mechanism is increased obviously.
On the other regard, when the bulb is embedded into the socket adapter, the terminal portion of the bulb is inserted into the key groove, and clamped by the clamping upper portion of the conducting strip tightly so that the two electrodes and the conducting strips are kept in a steady contact.
