Abstract

A water drainage structure of a christmas lamp comprises a lamp socket and a bottom cover. The inner wall of the lamp socket has screw threads and is provided with a straight slot in which a long conducting strip is embedded. The straight slot penetrates the bottom, and the center of the bottom is provided with a jack in which a short conducting strip can be inserted. The bottom of an electric bulb contacts the short conducting strip, and the side edge contacts the long conducting strip. The bottom of the lamp socket is provided with two inserting holes in which two positioning pieces extending out of the bottom cover can be inserted. The bottom cover is provided with a wire slot which presses the electric wire into the bottom of the lamp socket and the lunge pieces which are arranged on the long conducting strip and the short conducting strip are used for perforating the electric wire for switching on the power supply. The periphery of the bottom of the lamp socket is provided with at least one notch which is provided with a concave slot with definite length along the inner wall. Hereby, the utility model has water drainage function and is safe and reliable in using.

Description

The drain structure of Christmas lamp

The utility model system is relevant with Christmas lamp, more detailed it, refer to especially a kind of drain structure of Christmas lamp belong to the lamp decoration articles for use.

Press, in advance, Christmans light string can be placed in indoor and outdoor, when storing is outdoor, because dew, rainwater or snow infiltrate in the lamp socket, often cause moisture content to amass, cause bad, corrosion of conduction or electric leakage, even short circuit causes electric wire to cock off to cause disaster in the lamp socket conductive copper sheet, therefore, along with the improvement of product, the Christmas light socket that has is waterproof construction, have be discharge structure, wherein discharge structure, mostly establish hole at the bottom of lamp socket, but drainage effect is limited, still has seeping phenomenon, is not enough to solve above-mentioned drawback.

Main purpose of the present utility model is the drain structure that a kind of Christmas lamp is provided, and makes the interior moisture content of Christmas light socket discharge smoothly, even place the open air use of rainy day, also can keep good electrical conductivity, and no matter upright, handstand lamp socket all can be discharged moisture content.

The drain structure of a kind of Christmas lamp of the utility model, it is to include a lamp socket and bottom, this inboard wall of lamp holder is screw thread and the straight trough that is provided with long conducting strip embedding, straight trough also runs through the bottom, bottom center is established a jack in addition, plant for a short conducting strip, the short conducting strip of light bulb base contact, the long conducting strip of side contact, the lamp socket bottom has two embedded holes, plant for two spacers that bottom extended, and bottom is provided with wire casing, electric wire is pushed down in the lamp socket bottom, and pierced through electric wire with the thorn sheet that long conducting strip, short conducting strip are had and make turn-on power; It is characterized in that: this lamp socket bottom periphery is provided with at least one breach, and breach is prolonging inwall and is being provided with the groove of a length; In view of the above, utilize the breach of the groove of inboard wall of lamp holder and lamp socket bottom to discharge moisture content, and the lamp socket bottom notch do not enter by foreign matter, and stop, reach good draining purpose with the spacer of bottom.

Wherein, the groove length of this inboard wall of lamp holder is to the position more than the embedded hole from the lamp socket bottom.

The utility model has the advantages that: structural design has drain function, places the outfield to use, as runs into dark and damp rainy weather and also can normally use, can be because of the short circuit of raining, and safe and reliable.

The utlity model has following accompanying drawing:

Figure 1A, B, C are the utility model perspective exploded view.

Fig. 2. be the utility model lamp socket flat sheet of the bottom view.

Fig. 3 A, B. are the utility model lamp socket and bottom combination schematic diagram.

Fig. 4. be the utility model combination stereogram.

Number in the figure is as follows:

10. lamp socket 101. bottoms 11. straight troughs

111. long conducting strip 12. jacks 121. short conducting strips

13. embedded hole 14. breach 15. grooves

16. groove 20. bottoms 21. spacers

211. collude 22. wire casings, 30. bulbs

40. electric wire

Now details are as follows for embodiment and conjunction with figs.:

At first, see also Fig. 1, Fig. 2, shown in Figure 3, the drain structure of a kind of Christmas lamp of the utility model, it is to include a lamp socket 10 and a bottom 20, lamp socket 10 inwalls are screw-like, screw in for a bulb 80, lamp socket 10 inwalls have a straight trough 11 to run through bottom 101 in addition, there is a jack 12 in bottom 101 central authorities, and straight trough 11 is inserted for a long conducting strip 111, jack 12 is inserted for another short conducting strip 121, long conducting strip 111 and short conducting strip 121 are to coat with plastic cement, the part that only blanks contact bulb 30 and electric wire 40, lamp socket 10 bottoms have two embedded holes 13, be mainly square opening, system cooperates the spacer 21 of bottom 20 belows chimeric mutually, and spacer 21 ends collude 211, prevent to break away from embedded hole 13, make bottom 20 and lamp socket 10 driving fits, bottom 20 has two wire casings 22, and this is known Christmas lamp primary structure, and the utility model institute difference is that these lamp socket 10 bottom periphery are provided with several breach 14, and breach 14 is prolonging lamp socket 10 inwalls and is offering

groove

15,16, this

groove

15,16 length are to the position of embedded hole more than 13;

By above-mentioned composite construction, the drain structure of a kind of Christmas lamp of the utility model, bottom 20 is gone in the embedded hole 13 of lamp socket 10 with spacer 21 plants, and embedded hole 13 is to bottom 20, then leave groove 15 at spacer 21 peripheries, crack between 16, and

groove

15,16 do not influence the positioning bottom cap 20 of spacer 21, electric wire 40 holds to go in the wire casing 22 simultaneously, thrust for long conducting strip 111 and short conducting strip 212, as Fig. 2, shown in Figure 3, if lamp socket 10 infiltrates moisture content by bulb 30 1 ends, water can be from the groove 15 of embedded hole 13 peripheries, 16 and breach 14 discharge, if there is foreign matter to enter breach 14, then the spacer 21 of this bottom 20 stops, the long conducting strip 111 of unlikely destruction, short conducting strip 121; The utility model can be discharged moisture content in the lamp socket 10 by

groove

15,16 and breach 14, can not hoard in lamp socket, and if handstand lamp socket 10, owing to there is bottom 20 to cover, it is little that water infiltrates chances by this breach 14, even infiltrate, and also can be and adverse current is discharged by breach 14,

groove

15,16.
