Abstract
A Christmas lamp socket includes a housing, a lamp base with a lamp fitted therein and inserted in the housing completely. The housing has two aligned grooves in a bottom end for a power wire to be fitted and positioned therein with a proper tenseness so as to enable the sockets kept upright to the wire and thus to prevent rain from flowing in the housing and the lamp base and from consequent short circuit.
Description
' ~ CA 02204336 1997-0~-02 CHRISTMAS LAMP SOCKET
BACKGROUND OF THB INVENTION
This invention concerns a Christmas lamp socket, particularly having a two aligned grooves and two holes in a bottom portion for fitting electric power wires 60 as to save time and cost in assembling.
A known conventional Christmas lamp socket shown in Figs. 4 and 5 includes a housing 11, a lamp 12, a lamp base 13 and a power wire 14. The housing 11 has two opposite vertical tubular hooks 111, 111 for holding holding power wires 14, 14 in place.
However, the conventional Christmas lamp socket has drawbacks a6 listed below.
1. The vertical tubular hooks are definite in length, and it is not easy to insert the power wire therein. Besides, the tubular hooks may break if force used in inserting the power wire is too large, in addi-tion to the time needed in assembling being long to re-sult in high cost.

2. To form a mold for the housing with the tubu-lar hooks is rather difficult, resulting in a high cost.
3. If a net of Christmas lamps using the conven-tional sockets is hung outdoors, rain may flow in the housing and the lamp base to cause short circuit, which has latent danger for a possible fire.
' , CA 02204336 1997-05-02 SUMMARY OF TH~ INVENTION
A main purpose of the invention is to offer a Christmas lamp socket having a housing provided with two aligned grooves in a bottom portion for positioning a power wire, simplifying assembling a power wire with the housing.
Another purpose of the invention is to offer a Christmas lamp socket provided with two vertical holes in the bottom portion, ju~t for power wires to fit therein, so a lamp base may be completely inserted in a sealed condition so that rain may be prevented from flowing in the housing and the lamp base, without possi-bility of happening short circuit by rain.
The main feature of the invention is positioning grooves provided in a bottom end of the housing for fit-ting a power wire therein with a proper tenseness and two vertical holes also in the bottom end of the housing for just inserting respectively a power wire.
BRIEF DESCRIPTION OF DRAWINGS
This invention will be better understood by refer-ring to the accompanying drawings, wherein:
Figure 1 is an exploded perspective view of a first embodiment of a Christmas lamp socket in the pre-sent invention;
Figure 2 is a perspective view of a net of Christ-mas lamps using the sockets in the present invention;
Figure 3 is an exploded perspective view of a se-~ , ~ CA 02204336 1997-0~-02 , cond embodiment of a Christmas lamp socket in the pre-sent invention;
Figure 4 iD an exploded perspective view of a known conventional Christmas lamp socket; and, Figure ~ is a perspective view of a net of a Christmas lamps using the conventional Christmas soc-kets.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
A first embodiment of a Christmas lamp socket in the present invention, as shown in Figs. 1 and 2, in-cludes a housing 21, a conventional lamp 12, a lamp base 13 and a power wire 14.
The housing 21 has a center hole opening to an up-per side (a lower side in Fig. 1) and two aligned grooves 22, 22 in two opposite walls in a bottom end for a power wire to be fitted therein with a proper tense-ness for forming a net of Christ~mas lamps with the so-ckets.
The lamp 12 is fitted in the lamp base 13, and the lamp base 13 together with the lamp 12 is inserted com-pletely in the center hole of the housing 21.
Fig. 3 shows a second embodiment of a Christmas lamp socket in the present invention, which also in-cludes a housing 21, a conventional lamp 12, a lamp base 13 and a power wire 14.
The housing 21 of the second embodiment has a cen-ter hole opening to an upper side (a lower side in ~ig.
' , ~ CA 02204336 1997-05-02 3) for the lamp base 13 together with the lamp 12 to in-sert completely therein, a straight groove 22 for fit-ting a power wire 14 therein with a proper tenseness, and two vertical holes 23, 23 in the two opposite sides of the straight ~roove 22. The two hole8 23, 23 have a diameter a little larger than the diameter of the power wire 14 for the power wire 14 to pass through. Then the lamp base 13 may be said to be ~ealed in the housing 21 after the lamp base 13 is inserted in the housing 21, preventing rain from flowing in the housing to cause short circuit:.
Compared with the conventional Christmas lamp so-cket, that of the present invention has the following advantages.
1. A power wire is easily fitted in the aligned 8rooves of the housing, saving time for assembling and cost as well.
2. The aligned grooves need a comparatively simp-ler structured mold for reducing the cost for it.
3. The aligned grooves of the housing enable a power wire to be pulled in an upright direction to the lamp sockets, so the lamp sockets are kept in the up-right position to the surface of a roof or a wall, pre-senting 3D appearance, and in addition, also preventing short circuit from happening in rainy days.
