Abstract
The utility model discloses a kind of more pin-type adopting surface mounted LED encapsulating structures, it is related to LED encapsulation fields, including rack body and it is fixedly arranged on a plurality of metal electrodes of the rack body, the upper surface of the rack body is equipped with a light trough, the upper surface of the rack body is equipped with an annular step surface around light trough, and the annular step surface is equipped with a plurality of passages that light trough side wall is extended to from annular step surface.The beneficial effects of the utility model：When filling packaging plastic is packaged LED into light trough, since packaging plastic is in thick, there is certain fluidity, with reference to gravity, packaging plastic fills up whole light trough, while fills up each passage.After adhesive curing to be packaged, since packaging plastic forms a retaining ring in each passage, make mutual snapping between packaging plastic and rack body, can not come off easily, to ensure the service life of adopting surface mounted LED.
Description
Technical field
LED encapsulation fields are the utility model is related to, more specifically a kind of more pin-type adopting surface mounted LED encapsulating structures.
Background technology
LED due to its service life is long, small, high brightness, it is low in calories the advantages that be used widely in lighting area.
Existing LED generally includes to be installed with the rack body of metal electrode, chip and packaging plastic composition, rack body and is equipped with lamp
Groove.During production, chip is positioned in light trough and is connected it with metal electrode with tinsel, then it is close with transparent packaging plastic
Packing fills light trough and wraps up chip.
Existing light trough is in contraction-like usually from notch to slot bottom, to ensure the light range of exposures of LED and brightness, but it is this
There are problems with for light trough：Light trough is in contraction-like from notch to slot bottom, is in plane contact between light trough side wall and packaging plastic, encapsulation
Easily cause packaging plastic to loosen or even come off there are gap between glue and stent, influence the service life of LED.Therefore, one is designed
Kind can effectively prevent packaging plastic from coming off and can ensure that the light range of exposures of LED and the stent of brightness are necessary.
The content of the invention
The utility model provides a kind of more pin-type adopting surface mounted LED encapsulating structures, it is therefore intended that solves existing LED and there is envelope
The problem of easily coming off between dress glue and rack body.
The utility model adopts the following technical solution：
A kind of more pin-type adopting surface mounted LED encapsulating structures, including rack body and the plural number for being fixedly arranged on the rack body
A metal electrode, the upper surface of the rack body are equipped with a light trough, and the upper surface of the rack body is equipped with one around light trough
Annular step surface, the annular step surface are equipped with a plurality of passages that light trough side wall is extended to from annular step surface.
Further, the passage is L-shaped or c-type.
Further, the annular step surface is equipped with four equally distributed passages.
Further, the light trough is in up big and down small cone.
From the above-mentioned description to the utility model structure, the utility model has the following advantages that：
In the utility model, including rack body and a plurality of metal electrodes for being fixedly arranged on the rack body, the branch
The upper surface of frame body is equipped with a light trough, and the upper surface of the rack body is equipped with an annular step surface, the ring around light trough
Shape step surface is equipped with a plurality of passages that light trough side wall is extended to from annular step surface.Into light trough fill packaging plastic to LED into
During row encapsulation, since packaging plastic is in thick, there is certain fluidity, with reference to gravity, packaging plastic fills up whole light trough, together
When fill up each passage.After adhesive curing to be packaged, since packaging plastic forms a retaining ring in each passage, make packaging plastic and stent master
Mutual snapping between body, can not come off easily, to ensure the service life of adopting surface mounted LED.

Fig. 2 is the top view of the utility model.
Fig. 3 is the sectional view in the utility model A-A directions along Fig. 2.
Fig. 4 has filled the sectional view after packaging plastic for the utility model.
Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of more pin-type adopting surface mounted LED encapsulating structures, including rack body 1 with
And it is fixedly arranged on a plurality of metal electrodes 2 of the rack body 1.The upper surface of rack body 1 is equipped with a light trough 11, rack body 1
Upper surface be equipped with an annular step surface 12 around light trough 11, annular step surface 12 is equipped with a plurality of to be extended from annular step surface 12
To the passage 13 of light trough side wall.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, preferably：Annular step surface 12 is equally distributed logical equipped with four
Road 13.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, preferably：Passage 13 is L-shaped or c-type.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, preferably：Light trough 11 is in up big and down small cone.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept, should all belong to the row for invading scope of protection of the utility model
For.
