Further, the shell fragment is formed in one structure.
Further, on the stroke groove and it is equipped with radiating elongated hole on the drive division.
Further, screwed hole is offered on the lid.
Further, the pallet is provided with louvre, and the louvre is distributed in multiple PCB deep gouges surroundings.
Further, the louvre periphery is further opened with radiating groove.
Further, fixed part is provided with fixing pin and fixture louvre.
From above-mentioned to description of the present utility model, compared to the prior art, this utility model has the advantage that:
First, this utility model using cooperatively by upper fixing element and lower fixture, pcb board is fixed on pallet, its
In lower fixture using the pulling buckle of spring-piece type, not only pcb board can well be fixed, and dynamics is uniform, is unlikely to deform,
Long service life, extends the service life of tool, reduces production cost.
2nd, this utility model offers louvre on the surrounding of PCB deep gouges, upper fixing element and lower fixture, makes
Pcb board in reflow process and after Reflow Soldering is finished can Homogeneouslly-radiating, prevent pcb board due to radiating it is uneven caused by shape
Become and the problems such as LED dead lamp, increase the yields of product.
3rd, radiating groove has been added in the louvre periphery of PCB deep gouge surroundings in this utility model, has on the one hand reduced pallet
Thickness, accelerate radiating;On the other hand, convection current is formed between louvre and radiating groove, accelerates the volatilization of heat.
