Abstract

The utility model relates to a packaging structure for a decorative lamp, which comprises an outer sleeve 1, a lamp 2 and electric wires 3, wherein, two electric wires 3 are connected with the rear part of the lamp 2, the outer side of the junction of the rear part of the lamp 2 and the electric wires 3 is provided with the outer sleeve 1, sealing hot melt adhesive 5 is arranged between the two electric wires 3, the sealing hot melt adhesive 5 separates the two electric wires 3 and pastes and seals with the rear opening point of the outer sleeve 1, and a top opening of the outer sleeve 1 is also sealed. The utility model makes the inner wall of the outer sleeve and the sealing hot melt adhesive past together through the isolation of the two electric wires at the rear part of the lamp and the low temperature hot melt and the pasting sealing property of the hot melt adhesive. An interstice between the inner wall of the outer sleeve and the sealing hot melt adhesive is eliminated, making the lamp insolate with external environment, external water vapor or other gases are unable to enter into the lamp. Thereby, the working life of the lamp is longer, and failure rate is reduced greatly. The hot melt adhesive has the low temperature hot melt and the pasting sealing property, the manufacturing process is simplified greatly, the work efficiency is improved, and the manufacturing cost is reduced.

Description

A kind of encapsulating structure of decorative lamp

1, technical field:

The utility model relates to a kind of encapsulating structure of decorative lamp.

2, background technology:

Now, many cities are charming for the view that makes evening, use decorative lamps all in a large number on some buildings, because the decorative lamp great majority all use out of doors, and relative abominable of operational environment, so working life is very short, damages easily, changes cumbersome.Its structure as shown in Figure 1 and Figure 2, it comprises overcoat A, bulb B, electric wire C and electric wire spacing block D, two wire C are connected bulb B afterbody, the outside at bulb B afterbody and electric wire C junction surface is provided with overcoat A, electric wire spacing block D keeps apart bulb B afterbody two wire C, overcoat A does not seal bulb B afterbody fully in this structure, also there is space E between overcoat A and the electric wire spacing block D, airborne aqueous vapor or the aqueous vapor when rainy enter bulb B easily burns out bulb B, and be easy to generate spark, use dangerous; The common insulation plastic cement of the general employing of electric wire spacing block D is now made, difficult fusing distortion, and do not have viscosity, promptly the inwall of distortion back and overcoat A can not be bonded together, and therefore, is certain to exist the space.In addition, it is with whole bulb B and part electric wire C epoxy resin integral form that some solutions are arranged at present, its complex process, and processing difficulties, production efficiency are not high, and therefore the material cost height causes the entire product cost higher.

3, summary of the invention:

The purpose of this utility model provides a kind of encapsulating structure of decorative lamp, it is by keeping apart two wires of bulb tail with seal hot melting glue, low temperature hot melt and adhesive seal with PUR, make outer casing inner wall and seal hot melting glue bond together, eliminate the gap between them, make bulb and external environment isolated, extraneous aqueous vapor or other gas can not enter bulb, thereby make the working life of bulb longer, reduce its failure rate greatly, lower product cost.

The utility model is achieved by the following technical solution: it comprises overcoat, bulb and electric wire, two wires are connected bulb tail, the outside of bulb tail and wire-bonds portion is provided with overcoat, seal hot melting glue also is set between two wires, seal hot melting glue two wires are separated and with overcoat afterbody opening part adhesive seal, the open top of overcoat is also sealed.

Above-mentioned described overcoat can be a heat shrinking sleeve, and the top of heat shrinking sleeve and bulb outer surface are fitted and sealed, heat shrinking sleeve afterbody opening part and the sealing of seal hot melting glue bond, and heat shrinking sleeve tail end and electric wire are sticked together.

Above-mentioned described overcoat can be made up of bulb shell and heat shrinking sleeve, the outside of bulb is with the bulb shell, bulb shell top seal, bulb shell afterbody and the sealing of seal hot melting glue bond, heat shrinking sleeve is enclosed within the afterbody outside of bulb shell, the top of heat shrinking sleeve and bulb shell outer surface are fitted and are sealed, and heat shrinking sleeve tail end and electric wire are sticked together.

Above-mentioned described overcoat can be made up of bulb shell and heat shrinking sleeve, the outside of bulb is with the bulb shell, the outer surface adhesive seal of bulb shell top and bulb, bulb shell afterbody and the sealing of seal hot melting glue bond, heat shrinking sleeve is enclosed within the afterbody outside of bulb shell, the top of heat shrinking sleeve and bulb shell outer surface are fitted and are sealed, and heat shrinking sleeve tail end and electric wire are sticked together.

The utility model compared with prior art has following advantage: 1) it is by keeping apart two wires of bulb tail with seal hot melting glue, the low temperature hot melt of PUR and adhesive seal, make outer casing inner wall and seal hot melting glue bond together, eliminate the gap between them, make bulb and external environment isolated, extraneous aqueous vapor or other gas can not enter in the bulb, thereby make the working life of bulb longer, reduce its failure rate greatly; 2) seal hot melting glue has low temperature hot melt and adhesive seal, so can simplify its manufacturing process greatly, improves its operating efficiency, reduces manufacturing cost.
