Abstract

The utility model relates to an insertion type Christmas lamp holder with drainage function, which is composed of a base holder and a lamp holder body. Two penetrating drainage grooves are formed on the wall of the hollow cylinder part of the base holder. On the inner wall of the cuboid part of the lamp holder body, flow guiding grooves are correspondingly formed at a position which is in a line with drainage grooves. The flow guiding grooves and the drainage grooves are combined to form a first drainage passage. Two parallel through holes which are arranged in the cuboid part of the base holder are communicated with the hollow cylinder part to form a second drainage passage. Two drainage passages are combined at the positions of the drainage grooves of the base holder, which can eliminate the defect of unsmooth drain caused by the surface tension of water or air which retains in a passage and ensure that water accumulation is smoothly drained when lamp bulbs are at any position.

Description

Plug-in type Christmas light socket with drain function

The utility model relates to a kind of plug-in type Christmas light socket.

In countries in the world, especially American-European countries for celebrating Christmas Day and other red-letter days, adopts Christmas lamp as the usefulness that increases the decoration of festive air in a large number.And in various forms of Christmas lights, the consumption maximum surely belong to the plug-in type festival lamp luster that adopts miniature lamp.This lamp string purposes is the widest, can dress a Christmas tree, and can hang separately again; Can decorate indoor, can decorate outdoor again.But, decorate at outdoor lamp string and rain or snowy weather as if meeting, then the snow-broth of rainwater or thawing will be seeped in the lamp holder by stream.Traditional lamp holder assembly, as shown in Figure 1, its combination back cooperates tightr, there is not drainage channel, in case water enters in the lamp holder, just can gather wherein and can not in time discharge, easily cause between conducting

strip

321 and 322 to be short-circuited, the lamp string can't be used, even the meeting detonator circuit is on fire or the danger of personal electric shock.

The purpose of this utility model is to provide a kind of plug-in type Christmas light socket with drain function, and it can eliminate the danger of lamp holder internal short-circuit, thereby solves the defective on the conventional lights string structure.

Plug-in type Christmas light socket with drain function of the present utility model, it is made up of a pedestal and a lamp holder, pedestal comprises that one holds a hollow circuit cylinder body portion and the cuboid extension that bulb is used, lamp holder comprises a corresponding cylinder body cavity and a rectangular body cavity, be characterized in, be formed with two first rhones that penetrate on the wall of the barrel portion of pedestal, simultaneously, correspondingly be formed with two guiding gutters respectively with first rhone position in line on the inwall of the cuboid extension of lamp holder, they combine with first rhone, form the drainage channel of two symmetries, constitute article one drainage channel.

Above-mentioned plug-in type Christmas light socket with drain function, with in line position of first rhone, just be formed with two second rhones that do not penetrate respectively in the position relative with guiding gutter, they match with guiding gutter and enlarge the drainage channel area on the outer wall of the cuboid extension of its pedestal.

Above-mentioned plug-in type Christmas light socket with drain function, there are two parallel through holes the inside of the cuboid extension of its pedestal, communicate with the hollow circuit cylinder body portion of ccontaining bulb, constitute the second drainage channel, merge at the rhone place that these two drainage channels penetrate on the pedestal barrel portion again, forms the drainage channel of combined type, both separate, remedy mutually again, make draining more unobstructed.

In fact two drainage channels are arranged: article one path path that to be first rhone of pedestal and second rhone (if the words that have) form with the guiding gutter of lamp holder in lamp socket of the present utility model; The second path is that two parallel channels of wearing the bulb pin of pedestal cuboid extension communicate with the hollow circuit cylinder body portion of ccontaining bulb, have constituted drainage channel in line, the water that accumulates in pedestal and the lamp holder can be discharged.Owing to there are two drainage channels to act on simultaneously, thereby overcome effectively because the surface tension of water causes, or because the disadvantage of the impeded drainage that air trapping causes at passage, guarantee bulb no matter be up, down or during other positions, the ponding in the lamp holder all can be discharged swimmingly.And, its reasonable in design, drainage effect is remarkable, and production and assembly are convenient.Therefore, the utility model has both significant advance and desirable practicality.

A preferred embodiment of the present utility model is described below with reference to accompanying drawings, in the accompanying drawing:

Fig. 1 is the combination assumption diagram of prior lamp holder;

Fig. 2 is the three-dimensional exploded view of lamp socket of the present utility model;

Fig. 3 is the cutaway view of lamp socket of the present utility model after assembling.

As shown in Figure 2, lamp socket of the present utility model is made up of a pedestal 2 and a lamp holder 3.The top of pedestal 2 is hollow circuit cylinder body portions 21 of ccontaining bulb 1, two rhones that penetrate 231 and 232 are arranged on it, barrel portion 21 down is a cuboid extension 24, two relative

nonpenetrating rhones

241 and 242 are arranged on it, and rhone 231 and 241,232 and 242 is located respectively in a straight line, forms two drainage channels.

The top of lamp holder 3 is cylinder body cavitys 31, the hollow circuit cylinder body portion 21 that is used for ccontaining pedestal 2, the bottom is rectangular-shaped lock chamber 32, be used for fixing conducting

strip

321 and 322, simultaneously, when pedestal 2 inserted, the cuboid extension 24 of pedestal just in time was contained in this lock chamber 32, and bulb pin 111 is closely contacted with 322 with conducting strip 321 respectively with 112, make electric current be able to by.Bottom 33 openings of lock chamber 32, supply lines passes.On two faces of rectangular body cavity broadside, an interface 312 of having gone up cylinder and cuboid is respectively arranged, guiding

gutter

341 and 342 down to lamp holder bottom 33, they combine with

nonpenetrating rhone

241 and 242 on the pedestal 2 respectively, constitute the drainage channel of left-right symmetric, up/down perforation, rainwater or snow-broth are discharged from the bottom 33 of lamp holder, perhaps discharge from the slot 120 of bulb and pedestal.This is article one drainage channel.

The second drainage channel as shown in Figure 3, there are two through holes 251 parallel, each about 1.5 * 1.5mm and 252 in the inside of pedestal 2 cuboid extensions 24, communicates with the hollow circuit cylinder body portion 21 of ccontaining bulb 1.One of effect of these two through holes is to allow

bulb pin

111 and 112 pass, and two of effect is exactly another drainage channel of 24 bottoms 26 from hollow circular cylinder 21 to the cuboid part that constitutes pedestal.

Like this, article two, drainage channel was both separate, merge at rhone 231 that penetrates and 232 places again, the drainage channel of forming combined type, they are separate and remedy mutually, can eliminate because of the surface tension of water or because the obstructed defective of draining that air trapping causes in passage, when guaranteeing that bulb is in any position, the ponding in the lamp holder can both be discharged smoothly.

More than show a preferred embodiment of the present utility model, but those skilled in the art can carry out various variations to it under the situation that does not break away from the utility model scope, for example, can be provided with the position of rhone more than two and guiding gutter, change rhone and guiding gutter and size, or the like, all these all should be included within the scope of the present utility model.
