Description

Decorative chain

Technical field

The utility model relates to a kind of decorative chain.

Background technology

The version of lamp body and lamp socket is as follows in the lamp string commonly used at present, with reference to Fig. 1, power line 3 ' the electrode that connects lamp body 1 ' inserts in the draw-in groove of lamp socket 2 ', extend out from lamp socket 2 ' bottom then, lamp body 1 ' inserts in the lamp holder 5 ', and the pin of lamp body 1 ' contacts with the electrode of power line 3 ' to form and is electrically connected.Each root power line 3 ' penetrates lamp socket 2 ' when assembling, electrode is snapped in the lamp socket draw-in groove again and fixes, to prevent the electrode play, this operation must be finished by manually-operated, is difficult to realize mechanical automation production, causes production efficiency low, time-consuming taking a lot of work increases manufacturing cost.

In order to simplify above-mentioned manufacturing procedure, the improvement structure that has occurred a kind of lamp socket on the market, with reference to Fig. 2, it comprises removable lamp socket 2 " and sealed base 6 ", power line 3 " be provided be connected to lamp socket 2 " and sealed base 6 " between wire casing in; in when assembling; can be earlier with power line 6 " electrode insert lamp socket 2 " in; then sealed base 6 " with lamp socket 2 " match and seal power line 6 ", at last lamp body 1 will be housed " lamp holder 5 " insert lamp socket 2 " get final product, technology is simple, can realize the mechanical automation Assembling Production; the minimizing manually-operated, has improved production efficiency greatly.But above-mentioned improved lamp socket 2 " structure is comparatively complicated, volume is bigger, and it is also very loaded down with trivial details to make needed mould, and still has certain trouble on assembly technology, causes the increase of manufacturing cost accordingly.

Summary of the invention

The purpose of this utility model is to provide a kind of decorative chain, and it is simple in structure, can simplify assembly technology, is convenient to mechanical automation production, and saves material, reduction manufacturing cost.

The utility model is to realize above-mentioned purpose like this:

Decorative chain comprises the lamp body and the lamp socket that connect by power line, and lamp socket is provided with wire casing, and Power cord fastener is connected in the wire casing, it is characterized in that the lamp base of lamp body is sharply terminal, and it passes the conductor that through hole thrusts in the power line respectively and power line is interior on the lamp socket and is electrically connected.

In addition, filling has the power line jam between the bottom of power line and the wire casing.

The beneficial effects of the utility model are: structure is very compact, has saved material greatly, has reduced cost; When assembling, power line can be snapped in the wire casing of lamp socket, filling in Power cord fastener then fills in capable fixing, at last the lamp base of lamp body is thrust in the power line and get final product, technology is simple, can realize the mechanical automation Assembling Production, reduce manually-operated, improve production efficiency greatly, can reduce the use of materials such as lamp socket, power line simultaneously, reduced manufacturing cost.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is existing lamp string structure;

Fig. 2 is the structure of another kind of existing lamp string;

Fig. 3 is an assembling stereogram of the present utility model;

Fig. 4 is a lamp socket right view of the present utility model;

Fig. 5 is a fractionation stereogram of the present utility model.

The specific embodiment

With reference to Fig. 3 to Fig. 5, decorative chain comprises the lamp body 1 and the lamp socket 2 that connect by power line 3, lamp socket 2 is provided with wire casing 21, power line 3 is connected in the wire casing 21, and the lamp base of lamp body 1 11 is terminal sharp-pointed, and it passes to thrust respectively behind the through hole 22 on the lamp socket 2 in the power line 3 with the interior conductors of power line 3 and is electrically connected.This structure is very compact, save material greatly, reduced cost, and when assembling, earlier power line 3 is snapped in the wire casing of lamp socket, then the lamp base of lamp body is thrust in the power line 3 and get final product, technology is simple, can realize the mechanical automation Assembling Production, reduce manually-operated, improve production efficiency greatly.

For power line 3 is fixed in the wire casing, filling has power line jam 4 between the bottom of power line 3 and the wire casing 21, can prevent from like this in the use to lose efficacy owing to tractive lamp string causes getting loose between the lamp base of lamp body and the power line 3.Wherein said wire casing 21 bottom openings, opening 23 places are extended with guide rail 24 in wire casing, corresponding power line jam 4 is provided with guide groove 41, guide groove 41 is connected with guide rail 24, because lamp socket and power line jam 4 all are to adopt injection molding, certain elasticity is arranged, and this structure can increase the snap action of 4 pairs of power lines 3 of power line jam.Also have power line jam 4 to be provided with bulb holder hole 42 in the position of lamp socket through hole 22 correspondences, lamp base 11 penetrable power lines 3 stretch in the bulb holder hole 42, so exactly power line 3, lamp body, lamp socket and power supply jam are fixed together, even if the lamp string is subjected to pullling of big external force, power line 3 and power line jam can not get loose with lamp socket, have increased the reliability that structure connects greatly.

In general all be the power line that adopts two cores, the heart yearn outer wrap has insulated hull and mutually insulated, and the insulated hull between heart yearn all can form groove usually.In order to guarantee that the power line 3 and the lamp base position of lamp body are complementary, the surface that wire casing 21 and power line jam 4 contact with power line 3 is respectively equipped with fin 25,43, like this when power line 3 snaps in wire casing, fin will snap in the groove of power line 3, it can not be twisted, better power line 3 is positioned.

For energy-conservation consideration, this decorative chain has adopted LED as lamp body, because LED is to should be noted that the both positive and negative polarity of distinguishing power supply in wiring, otherwise can be not luminous, therefore be provided with lamp body mounting groove 26 at lamp socket 2, the through hole 22 of cell body bottom for allowing lamp base 11 pass, the shape of lamp body mounting groove 26 and lamp body 1 adapt, so just can avoid LED may occur the problem of reversal connection when mounted, more help the mechanical automation Assembling Production.
