Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of auto rectifier diode base.
Background technology
At present, automobile engine pressing type rectifier diode is straight wire rectifier diode, and the rectifier usually diode being assemblied in automobile current generator uses, and its lead-in wire welds with rectifier bracket.But when diode and rectifier heating panel assemble, be adopted by diode the form of interference fit base portion to be squeezed in the hole of rectifier heating panel, this extruding force is larger by the impact of the factor such as bore dia size, rectifier heating panel hardness of diode base groove diameter dimension, diode base hardness, rectifier heating panel.Therefore, the extrusion stress produced when diode press-in rectifier heating panel may be delivered on chip, causes chip rupture, thus causes whole defective rectifier, generator cisco unity malfunction.In addition, then in the base being welded with chip and wire during encapsulating, the problems such as encapsulating is insufficient may be faced.
Therefore, based on these problems, provide a kind of encapsulating convenient, improving encapsulation ability to diode chip for backlight unit, can better a kind of auto rectifier diode base of protect IC have important practical significance when assembling with rectifier heating panel.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the auto rectifier diode base that a kind of encapsulating is convenient, improve encapsulation ability to diode chip for backlight unit, protect IC.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of auto rectifier diode base, comprise firm banking, base stage, outer jointing jacket, chip holder, chip protective sleeve, described base stage, firm banking, outer jointing jacket is one-body molded, described base stage bottom surface is provided with annular boss, described firm banking outer surface is provided with dentation decorative pattern, reject chute is formed between described outer jointing jacket and described chip protective sleeve, it is characterized in that: described outer jointing jacket comprises protective sleeve base and protection jacket wall, described protective sleeve base outer wall is centroclinal to base, described protection jacket wall is located at described protective sleeve base upper surface, described outer jointing jacket is trapezium structure towards the one side of described reject chute, described chip protective sleeve and described firm banking one-body molded, described chip protective sleeve circle centre position is located in described chip holder, formed with described chip protective sleeve and encapsulate groove, described encapsulation groove is wide at the top and narrow at the bottom trapezoidal, the height of described chip holder is lower than described chip protective sleeve, described chip holder outer surface and described encapsulation rooved face form inclination ruggedized construction.
Further, described dentation decorative pattern is 78 teeth, and the dentation degree of depth is 0.16 ± 0.02mm, and decorative pattern spacing is 0.5mm.
Advantage of the present utility model and good effect are:
(1) chip holder of the present utility model and chip protective sleeve are positioned at the upper surface of firm banking, and after encapsulating completes press-in rectifier heating panel, the direct radial direction of extrusion stress avoiding generation is delivered on chip, protects chip.
(2) the utility model is by adopting trapezoidal chip protective sleeve, makes to be more prone to for chip perfusion during encapsulating; Chip holder outer surface forms inclination ruggedized construction with encapsulation rooved face, makes chip holder structure more firm; Form reject chute between outer jointing jacket and chip protective sleeve, encapsulating effect is more substantial; Outer jointing jacket is trapezium structure towards the one side of reject chute, better to the protected effect of chip after encapsulating.
