Utility model content
The purpose of this utility model is to provide a kind of novel injection molding type lamp holder, fundamentally solves injection moulding sizing material and pours cell-shell and the poor problem of water resistance.
The technical scheme that the utility model adopted is for achieving the above object:
An injection molding type lamp holder, it is characterized in that: comprise
One LED, comprises packaging body and lamp base;
The wire being electrically connected to the lamp base of described LED;
There is the printing opacity cell-shell of cavity one inside, and the packaging body of described LED is placed in cavity;
Be installed on the openend of described printing opacity cell-shell, for the seal of sealed cavity, described seal is provided with the through hole that the lamp base with LED matches, the lamp base of described LED is through through hole, described seal is partly placed in the cavity inside of printing opacity cell-shell, and is filled with resin between the lamp base of LED and through hole;
By the lamp socket of injection mo(u)lding, lamp base and the electric connection point between wire, the seal of the afterbody of the coated printing opacity cell-shell of described lamp socket, part wire, LED are exposed at the part outside cell-shell.
Further, described seal comprises insertion section, and described insertion section is placed in the openend inside of printing opacity cell-shell.
Further, described seal also comprises push stopping part, and described push stopping part protrudes from bottom, insertion section, and stop bit is in the openend outer of printing opacity cell-shell.
Further, described seal is provided with a circular groove, and described circular groove surrounds the part packaging body of LED.
Further, the packaging body of described LED and seal fit tightly
Further, described through hole is narrowed down by wide from top to bottom.
Further, be provided with a separator between the lamp base of described LED, described separator is positioned at the below of seal, and described separator is by the lamp base of LED and the isolation of part wire.
Further, the outer surface of described printing opacity cell-shell is provided with at least one annular groove, and described annular groove is coated by lamp socket.
Further, described resin is epoxy resin or organic siliconresin.
The beneficial effects of the utility model are: owing to being filled with resin between the lamp base of LED and the through hole of seal, in the process of lamp socket injection mo(u)lding, prevent that sizing material from pouring cell-shell cavity from the space between lamp base and the seal of printing opacity cell-shell, stop up cell-shell and scorch LED, in long-term use procedure, also avoid the moisture entering from the space between wire and lamp socket further to infiltrate cell-shell cavity, improved greatly the water resistance of lamp holder.
