Utility model content

In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide the saturating LED support of a kind of Novel seepage, by circular step being set in reflective rim of a cup, groove and bending part are set on conductive pin, make reflective rim of a cup and epoxy resin associativity better, conductive pin is combined interlock with plastic base tightr, overall structure is more firm, improves the impermeable ability of LED support.

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

The saturating LED support of a kind of Novel seepage, comprises plastic base and plural conductive pin, and this plastic base has a package cavity, in this package cavity, is formed with reflector; This conductive pin includes the die bond portion, extension and the leg portion that are integrally formed, this die bond portion passes plastic base and puts in reflector, this extension is embedded in plastic base, this leg portion is exposed to outside plastic base, described reflective rim of a cup is provided with and makes it be combined step more closely with the epoxy resin of encapsulated reflecting cup mouth, and this step is surrounded on reflective rim of a cup one week; Each conductive pin is provided with respectively for making conductive pin be combined groove more closely with plastic base near reflective rim of a cup place; The extension of each conductive pin is recessed to form a bending part for increasing conductive pin and plastic base linking steady character to the inside.

As a kind of preferred version: the transverse part that described bending part includes vertical portion and is attached thereto, this vertical portion is connected with the rectangular shape of transverse part.

As a kind of preferred version: described groove is square.

As a kind of preferred version: the groove of described each conductive pin after connecting in the form of a ring.

As a kind of preferred version: described plastic base bottom is provided with the accommodating recess for the leg portion of accommodating conductive pin, and the leg portion of plural conductive pin bends respectively and is placed in accommodating recess.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, by circular step being set in reflective rim of a cup, groove is set on conductive pin, the bending part that can combine closely with plastic base is set on the extension of conducting terminal, make the reflective rim of a cup of LED support in the time of encapsulating epoxy resin, reflective rim of a cup can be better by step and epoxy resin associativity, permeability resistance is stronger, simultaneously, conductive pin by upper recess thereof groove and bending part in the time that plastic base is combined, interlock is tightr each other, structure is more firm, anti-permeability is better.

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.
