Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
embodiment mono-.
As shown in Figures 1 to 4, a kind of pcb board that improves the installation reliability of socket of the present embodiment, comprise substrate 1 and socket 2, socket 2 is arranged at the top of substrate 1, substrate 1 offers the jack 11 through substrate 1, on socket 2, be provided with " L " shape pin 21, " L " shape pin 21 comprises longitudinal pin body 212 and horizontal pin body 211, longitudinally pin body 212 is longitudinally inserted in jack 11, laterally pin body 211 is passed by the tail end of longitudinal pin body 212 that jack 11 is rear to be extended and form towards horizontal direction, and laterally pin body 211 is positioned at the lower surface of substrate 1.The utility model is simple in structure, because the pin of socket 2 is " L " shape pin 21, " L " shape pin 21 wore after jack 11 can back-off in the lower surface of substrate 1, strengthened the connective stability of pin and substrate 1, replaced traditional single welding manner, " L " shape pin 21 is strong with the connection reliability of the jack 11 of substrate 1, long service life.
In the present embodiment, the lower surface of substrate 1 is provided with pad 3, and the surface of pad 3 is provided with connector 4, and laterally the end of pin body 211 is connected in connector 4, and connector 4 is scolder connector.The end of pin of the present utility model is connected with substrate 1 by scolder connector, has further strengthened the connective stability of pin and substrate 1, greatly improves the installation reliability of socket 2 and substrate 1, further extends useful life of the present utility model.
In the present embodiment, pad 3 comprises interconnective pad body 31 and extension 32, and extension 32 stretches out from the edge of pad body 31.Pad body 31 is convenient to scolder connector and is attached on substrate 1, and extension 32 has increased the area of pad 3, and then has strengthened the adhesive force of pad 3 with substrate 1, thereby guarantees the connective stability of scolder connector and pin end.
In the present embodiment, pad body 31 is circular pad body, the central part of circular pad body offers through hole 321, pad body 31 is annular, the through hole 321 at middle part can avoid stress to concentrate on center, effectively prevent stress from concentrating and cause pad 3 to break, greatly improve the cohesiveness of pad body 31, structural stability is high.
In the present embodiment, extension 32 comprises four extension bars that are evenly arranged at the outer ring of circular pad body 31, and four are extended all types linearly of bar, and every two angles that extend between bars are right angle.By four, extend the pad 3 that bars and circular pad body 31 connect and compose and be cross, the stress of pad 3 is dispersed to four direction equably, has greatly strengthened and between pad 3 and substrate 1, has had preferably adhesiveness and bonding force.
