In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide a kind of Novel surface mount type LED bracket, by conductive pin and reflecting cup structure are improved, improve the relative steadiness of conductive pin and plastic base, the contrast, luminous exitance and the reliability that have improved LED can be applicable to high-end field simultaneously.

For achieving the above object, the utility model adopts following technical scheme:

A kind of Novel surface mount type LED bracket, comprises plastic base and is embedded in the plural conductive pin on plastic base, this plastic base has a package cavity, is formed with a reflector in this package cavity; This conductive pin includes integrated die bond portion, extension and leg portion, and this die bond portion is positioned at reflector, and this extension is embedded in plastic base, and this leg portion is exposed to outside plastic base, and the reflector inwall of described plastic base is curved; The extension indent of described conductive pin forms one 90 degree bending parts, and this bending part includes vertical portion and is vertically connected at the transverse part of vertical portion lower end, and this vertical portion and above-mentioned die bond portion join, and this transverse part and above-mentioned leg portion join.

As a kind of preferred version: described plastic base entirety is black.

As a kind of preferred version: described plastic base is white plastic, and is coated with black ink layer on plastic base lateral wall.

As a kind of preferred version: the reflective rim of a cup place of described plastic base is provided with for the step with the better combination of encapsulation plastic cement.

As a kind of preferred version: described vertical portion height is 0.95mm.

As a kind of preferred version: described LED support length is 2.80mm, and width is 2.70mm, is highly 2.45mm.

As a kind of preferred version: described plastic base bottom is provided with storage tank, and the leg subordinate of conductive pin holds bending to extend and is buckled in this storage tank.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, be set to the structure being vertically connected with transverse part by vertical portion by the extension of conductive pin, make after conductive pin and plastic base produced by insert molding, steadiness is better; In addition, reflector inwall is arranged to arc, this curved reflection cup inwall props up line style reflector inwall with respect to tradition, in contrast, luminous exitance and reliability, by very large lifting, can be applicable to high-end field.

For more clearly setting forth architectural feature of the present utility model and effect, be described in detail below in conjunction with accompanying drawing and specific embodiment.

Detailed description of the invention

The utility model is as shown in Fig. 1 to Fig. 3 and Fig. 5, and a kind of Novel surface mount type LED bracket, includes plastic base 10 and be embedded in the plural conductive pin 20 on plastic base 10, wherein:

This plastic base 10 has a package cavity 11, in this package cavity 11, be formed with a reflector 111, these reflector 111 inwalls are curved, be provided with in 111 mouthfuls of places of reflector for the step 1111 with the better combination of encapsulation plastic cement, this step 1111 can improve reflector 111 is combined compactness with encapsulation plastic cement, and permeability resistance is better; These plastic base 10 entirety be black or entirety for white plastic, and on white plastic base 10 lateral walls, apply black ink layer 12, entirety can effectively improve the contrast of product for black or LED support that only lateral wall is black; These plastic base 10 bottoms are concaved with storage tank 13.
