Description

The miniature lamp combining structure

The utility model relates to the combining structure of a kind of bulb and lamp socket, particularly a kind of miniature lamp combining structure.

After commonly using miniature lamp and lead being connected, be to macerate prolongation with chemical agent, make it coat bulb pin and wire bonds place, with polyvinyl chloride heat-shrinkable tube fit with wire insulation foreskin heating prolongation or with the wire insulation foreskin.But said structure easily causes defective insulation, insulating covering aging easily, thereby reduces bulb service life.Moreover, the said structure processing time consuming, and increase production cost.For effectively solving the above-mentioned problem of commonly using miniature lamp, the real utmost point needs a kind of bulb combining structure of improvement.

Main purpose of the present utility model is to overcome the shortcoming of prior art and a kind of miniature lamp combining structure is provided, to increase its insulation effect and bulb service life.

Another purpose of the present utility model is to provide a kind of miniature lamp combining structure, is easy to processing, to reduce production costs.

The purpose of this utility model reaches as follows:

A kind of miniature lamp combining structure, it comprises:

One miniature lamp has an outer wall and two pins;

One connects lead, is connected to this two pin;

One soft silicone tube fit bulb outer wall and connection lead; And the polyvinyl chloride heat-shrinkable tube is sleeved on outside the soft silicone tube;

It is characterized in that: be full of the liquid silica gel that solidifies in the soft silicone tube around bulb pin and the lead junction.

Effect of the present utility model mainly is:

The utility model is because soft silicone tube and silica gel belong to identical material, in conjunction with very firm.Moreover the chemical characteristic of silica gel is fit to combine with glass, thereby sealing is good, and water proofing property spy is good.Therefore, the utility model bulb combining structure is applicable to various climatic environments, and applicable temperature circle is between-62 ℃ to+210 ℃, and bulb can use continuously for a long time, does not comparatively commonly use the person and is difficult for aging.In about 20,000 hours of the service life of the utility model bulb combining structure,, can use 5 years approximately as using ten hours meters every day.Moreover, because of silica gel sealing excellent, and waterproof, can be in outdoor or be dipped in the water and use for a long time.

In addition, the utility model bulb combining structure can exempt commonly use miniature lamp and lead be connected after, macerate prolongation with wire insulation foreskin heating prolongation or with the wire insulation foreskin with chemical agent, make it coat the procedure at bulb pin and wire bonds place, and handling ease can significantly reduce production costs.

Relevant the utility model detailed technology content and preferred embodiment please refer to following graphic and detailed description.

Fig. 1 is the decomposing schematic representation of the utility model miniature lamp combining structure;

Fig. 2 is the profile of the utility model miniature lamp combining structure;

Fig. 3 is the stereogram of the utility model preferred embodiment.

At first please refer to Fig. 1, according to miniature lamp combining structure of the present utility model, it comprises that mainly a miniature lamp 1, connects lead 2, a soft silicone tube 3 fit bulb outer walls and connection lead and a polyvinyl chloride heat-shrinkable tube 4 is sleeved on outside the soft silicone tube.According to miniature lamp combining structure of the present utility model, be that first two pins 11,12 with bulb 1 weld with scolding tin with two leads 21,22 that are connected lead 2, again with soft silicone tube 3 fit bulbs, 1 outer wall and connection lead 2.Inject bulb 1 and lead 2 junctions in the soft silicone tube 3 with liquid silica gel 31 then, make liquid silica gel 31 that bulb 1 in the soft silicone tube 3 and lead 2 junctions are formed insulated enclosure.At last, be sleeved on outside the soft silicone tube 3 with polyvinyl chloride heat-shrinkable tube 4 again.

Please refer to Fig. 2 and Fig. 3, when soft silicone tube 3 fit bulbs 1 outer wall, because of the joint sealing between silica gel and glass excellent, can make the bulb 1 glass outer wall tight seal of silicone tube 3 and fit, when reinjecting liquid silica gel 31 bulb 1 is with lead 2 junctions in soft silicone tube 3, air can be got rid of anti-oxidation and form the good insulation sealing.At last, be sleeved on outside the soft silicone tube 3 with polyvinyl chloride heat-shrinkable tube 4 again, polyvinyl chloride heat-shrinkable tube 4 shunk, form double shielding and gain in strength with hot blast.
