Abstract

The utility model discloses a twinkle light, comprising a wire and a bulb holder which is arranged on the wire. The bulb holder is provided with a wire hole, including an insulation body shell and an inner wire connector; and at one end of the wire connector is provided with a lamp base tube which is communicated with the wire hole while the other end of the wire connector is provided with a wire-clamp duct; and the center yarn of the wire is arranged in the wire-clamp duct. As one end of the wire connector positioned in the bulb holder is provided with the wire-clamp duct, the center yarn of the wire is arranged in the wire-clamp duct to realize electricity connection and due to the contact area of the wire-clamp duct and the center yarn of the wire relatively widens, the connection of the wire-clamp duct and the center yarn of the wire becomes much firmer and steadier. When in use, the utility model can hold the wire and the wire connector firmly together even owing to a plurality of drags so that to assure a regular working of the twinkle light.

Description

A kind of decorative chain

Technical field

The utility model relates to a kind of decorating lighting lamp, particularly a kind of decorative chain with waterproof effect.

Background technology

The lamp string is as a kind of decorating lighting lamp, be widely used in and beautify the environment, fields such as advertising, play the decoration function of heighten atmosphere, common decorative chain is for ease of installing, generally lamp socket is interconnected by electric wire, but because existing holder structure is all very simple, comprise insulation shell and be fixed on interior pair of terminals of housing, power line pass behind the insulation shell with housing in binding post by twisting joint or mode such as welding is connected, because these insulation shells mostly are independently little box body, only pass by offer line hole power supply source line in the side, so after repeatedly using, owing to be subjected to being easy to get loose between tractive electric wire and binding post, cause fault such as open circuit, have a strong impact on the operate as normal of lamp string.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide more stable, the firm decorative chain that is connected between a kind of simple in structure, electric wire and binding post.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of decorative chain, comprise electric wire and the lamp socket that is fixed on the electric wire, described lamp socket is provided with plug wire hole, described lamp socket comprises insulation shell and built-in binding post, described binding post one end is provided with the lamp base tube and is communicated with plug wire hole, the binding post other end is provided with the clamp groove, and the heart yearn of described electric wire is installed in the described clamp groove.

As the utility model preferred embodiment, described housing integral molded plastic is formed in outside described binding post and the electric wire.

The beneficial effects of the utility model are: binding post one end in the utility model lamp socket is provided with the clamp groove, the heart yearn of electric wire is installed in to be realized in the clamp groove being electrically connected, because the contact area of clamp groove and electric wire heart yearn obviously increases, so connection therebetween is more stable, more firm, even in the use repeatedly tractive can not cause electric wire and binding post to break away from yet, thereby guaranteed the operate as normal of decorative chain; When the lamp housing of forming lamp socket is that integral molded plastic is when being formed in outside built-in binding post and the electric wire, also can make the interface of housing and electric wire have good sealing effectiveness, thereby can prevent that rainwater from entering lamp socket inside, avoid occurring faults such as lamp socket short circuit, and being connected between electric wire and lamp socket is also more reliable; The shell that this integral molded plastic is shaped also can be provided with many set of connections terminal and electric wire in same lamp socket, so that insert a plurality of bulbs of system, enrich the decorative effect of lamp string.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the perspective view of a kind of embodiment of the utility model;

Fig. 2 is electric wire and a connection terminal structure schematic diagram among Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of decorative chain, comprise electric wire 1 and the lamp socket 2 that is fixed on the electric wire 1, wherein lamp socket 2 is provided with plug wire hole 21, lamp socket 2 comprises insulation shell and built-in binding post 23, and binding post 23 1 ends are provided with the lamp base tube 231 that is communicated with plug wire hole 21, and binding post 23 other ends are provided with clamp groove 232, the heart yearn of electric wire 1 is installed in the described clamp groove 232, and the insulation shell integral molded plastic is formed in outside described binding post 23 and the electric wire 1.

In the present embodiment, a pair of plug wire hole 21 is arranged on each lamp socket 2, lamp socket 2 is shaped with the electric wire integral molded plastic, as shown in Figure 2, because lamp socket 2 built-in binding posts 23 are "T"-shaped lamp base tube 231 and the clamp groove 232 of being distributed with, lamp base tube 231 communicates with plug wire hole 21, and the heart yearn of each electric wire 1 is installed in the clamp groove 232, because the contact area of electric wire 1 heart yearn and clamp groove 232 has increased, so its electrical connection is more reliable, the housing integral coating of lamp socket 2 is outside each binding post 23 and electric wire 1, this structure not only guarantees not have between electric wire and the housing slit, play preventing that rainwater from infiltrating the effect in the housing, but also can prevent to make electric wire 1 break away from lamp socket 2 owing to leading to connect wires.Can be used to locate binding post 23 and electric wire 1 simultaneously.

In the above-described embodiments, in the insulation shell a plurality of binding posts 23 and corresponding electric wire 1 can also be set as required,, enrich the decorative effect of lamp string so that insert a plurality of bulbs of system.
