Abstract
The invention relates to the design technology of a printed circuit board (PCB), in particular to a packaging structure of a two-pin element. The structure comprises the two-pin element and the PCB. The PCB is provided with a first jack and a second jack respectively corresponding to a first pin and a second pin of the two-pin element. A welding disc is arranged along the jack edges of the first jack and the second jack. According to the element standard, the first jack and the second jack should be round jacks. The first jack is arranged to be a round jack according the element standard, and the second jack is not arranged according to the element standard but arranged to be a strip hole. The strip hole passes through the round hole arranged according to the element standard, the width of the strip hole is equal to the diameter of the round hole, and the length of the strip hole is larger than the diameter of the round hole, so that the second jack can adapt to the change of distance between the second pin and the first pin after the first pin is inserted. The packaging structure of the two-pin element improves production efficiency and simultaneously ensures packaging quality.

Embodiment
As depicted in figs. 1 and 2, the encapsulating structure of two pins element comprises two pins element 2 and pcb board 1, pcb board 1 has the first pin 21 and second pin 22 of the first jack 11 and the corresponding two pins element 2 of the second jack 12 difference, limit, hole along the first jack 11 and the second jack 12 is provided with pad 3, according to the element standard, the first jack 11 and the second jack 12 all should be circular hole, the first jack 11 is just offered according to the element standard and is circular hole, the second jack 12 is offered not according to the element standard and is offered and is the strip hole, the strip aperture is crossed the circular hole place that should offer according to the element standard, the width in strip hole equals the diameter of circular hole, the length in strip hole is greater than the diameter of circular hole, so that after the first pin 21 inserted, the second jack 12 can adapt to the variation of the second pin 22 to first pins 21 distances.
If the strip hole is offered take the first jack 11 as center of circle circumference, the first jack 11 and 12 of the second jacks can not adapt to the variation of the first pin 21 to second pins 22 distances of unusual element, so the strip hole should be offered as adapting to the variation of the second pin 22 to first pin distances.
Owing to the second jack 12 is offered not according to the element standard and is the strip hole, the strip aperture is crossed the circular hole that should offer according to the element standard, the width in strip hole equals the diameter of circular hole, this technical characterictic empty situation of welding can not occur after can making 22 grafting of the second pin enter the second jack 12, and the length in strip hole is greater than the diameter of circular hole, so that after the first pin 21 inserts, the second jack 12 can adapt to the variation of the second pin 22 to first pins 21 distances, can so that pegging graft, the first pin 21 have the second pin 22 grafting that certain scope is convenient to unusual element to enter the second jack 12 behind the first jack 11, improve production efficiency, guaranteed simultaneously the encapsulation quality.
Two pins element 2 is in concrete encapsulation process, and the first pin 21 inserts first the first jack 11, then the second pin 22 is inserted the second jack 12, finally realizes encapsulation by welding.
The second jack 12 is rectangular opening, described rectangular opening comprises limit, the first hole 121, limit, the second hole 122, limit, the 3rd hole 123 and limit, the 4th hole 124, limit, the first hole 121 is parallel with limit 123, the 3rd hole, the distance on limit, 121 to the 3rd hole, limit, the first hole 123 is the diameter of circular hole, and the distance on limit, 122 to the 4th hole, limit, the second hole 124 is greater than the diameter of circular hole.
And the distance on limit, 122 to the 4th hole, limit, the second hole 124 is greater than the diameter of circular hole, can be so that the first pin 21 pegs graft behind the first jack 11 the second jacks 12 have the second pin 22 that certain scope is convenient to unusual element to peg graft easily to enter the second jack 12, improve the production efficiency of two pins element 2 encapsulation, guaranteed simultaneously the encapsulation quality.
Preferably, the extended line on limit, the first hole 121 and limit, the 3rd hole 123 is all tangent with the first jack 11, and as shown in Figure 1, this setting can be so that the second pin 22 can access maximum scope of activities behind second jack 12 of pegging graft.
Preferably, the distance on limit, 122 to the 4th hole, limit, the second hole 124 is 1.5 times or 2 times of diameter of circular hole.
When described pcb board 1 was single sided board, the diameter of circular hole was than the large 0.3mm of diameter of pin.
When described pcb board 1 was double sided board, the diameter of circular hole was than the large 0.4mm of diameter of pin.
Should be noted that at last; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although with reference to preferred embodiment the present invention has been done to explain; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from essence and the scope of technical solution of the present invention.
