Abstract
The invention discloses a plug-in package piece. Bosses are arranged at a lower end of a plastic shell, pins are directly inserted into bonding pad holes of a PCB (Printed Circuit Board) during welding, so that the bosses are in contact with surfaces of bonding pads for welding. By the structure, the insertion depths of the pins of the package piece can be effectively ensured, and the package piece is enabled to be prevented from being damaged during the welding process.
Description
Technical field
The invention belongs to plug-in unit encapsulating structure is and in particular to a kind of plug-in unit packaging part.
Background technology
During existing plug-in unit encapsulating structure, need plug-in unit to be encapsulated the metal of (to-220, to-251, to-247, to-3p etc.)
Pin is fully inserted in the pad hole of pcb, and metal step at plug-in unit metal pin can only be relied on to control height.For example, if
When the step width of metal pin is less than pcb pad hole, the pin of device will be fully inserted in pad hole, plastic packaging material directly with
Pcb plate contacts, and easily causes weld failure；If the step width of metal pin is more than pcb pad hole, the pin of that device
Insertion pcb pad hole is arrived and is ended at metal pin step, can not meet requirement for height.
Content of the invention
It is an object of the invention to provide a kind of plug-in unit packaging part, to overcome the deficiencies in the prior art, the present invention can have
Effect solves welding and height problem.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of plug-in unit packaging part, including plastic shell, plastic shell lower end is provided with pin, and plastic shell lower end is provided with convex
Platform.
Further, wherein plastic shell lower end is provided with multiple pins.
Further, boss is plastic packaging boss.
Further, wherein boss is arranged on outside pin and plastic shell junction.
Compared with prior art, the present invention has a following beneficial technique effect:
Pin, by being provided with boss in plastic shell lower end, in welding, is directly inserted by a kind of present invention plug-in unit packaging part
Enter in the pad hole of pcb, so that boss is contacted with bond pad surface, welded.This structure can effectively ensure that the pin of packaging part
Insertion depth it is ensured that not damaging packaging part in welding process, meanwhile, plastic shell lower end setting boss can increase metal
Creep age distance between pin.
Further, boss is plastic packaging boss, is easy to boss and fixes with plastic shell, pin is protected.
Brief description
Fig. 1 is present configuration schematic diagram.
Wherein, 1, plastic shell；2nd, pin；3rd, boss.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail:
As shown in figure 1, a kind of plug-in unit packaging part, including plastic shell 1, plastic shell 1 lower end is provided with pin 2, outside plastic packaging
Setting control device in shell 1, pin 2 is connected with the control device in plastic shell 1；Wherein plastic shell 1 lower end be provided with multiple
Pin 2, plastic shell 1 lower end is provided with boss 3, and boss 3 is plastic packaging boss, and wherein boss 3 is arranged on pin 2 and plastic shell 1
Outside junction.By arranging plastic packaging boss in plastic shell 1 lower end, in welding, directly pin 2 is inserted the pad of pcb
Kong Li, is made boss 3 be contacted with bond pad surface, is welded.This structure can effectively ensure that the insertion of the pin 2 of packaging part is deep
Degree is not it is ensured that damage packaging part in welding process.
