Description

Известны выводы дл  маломощных транзисторных триодов, используемые при монтал е их в печатных платах.Known pins for low-power transistor triodes used in mounting them in printed circuit boards.

Предлагаемое изобретение состоит в том, что дл  повышени  производительности и надежности монтажа концы твердых выводов изогнуты в виде незамкнутой петли, коротка  часть которой отогнута под пр мым углом в направлении от нродольной оси петли.The present invention consists in the fact that, in order to increase the productivity and reliability of the installation, the ends of the solid leads are bent into an open loop, the short part of which is bent at a right angle in the direction from the longitudinal axis of the loop.

На фиг. 1 изображен маломощный транзисторный триод с твердыми выводами предлагаемой конструкции; на фиг. 2 - впа нный в печатную плату твердый вывод транзисторного триода в разрезе.FIG. 1 shows a low-power transistor triode with solid leads of the proposed design; in fig. 2 - solid cross section of transistor triode, sunk into the printed circuit board.

Твердые выводы / маломощного транзисторного триода 2 изогнуты в виде незамкнутой петли 3, конец 4 которой отогнут под пр мым углом в направлении от продольной octi петли.Solid leads / low-power transistor triode 2 are bent in the form of an open loop 3, the end 4 of which is bent at a right angle in the direction from the longitudinal loop of the loop.

Монтируютс  выводы следующим образом.Mounted conclusions as follows.

Благодар  нижней округленной части нетли вывода транзисторного триода выводы плавно вставл ют в отверсти  5 печатной платы 6. При этом отогнутые концы 4 выводовDue to the lower rounded part of the no output of the transistor triode, the leads are gently inserted into the holes 5 of the printed circuit board 6. At the same time, the bent ends of the 4 leads

ориентируют триод и служат упором при закреплении выводов в печатной плате 6. Петл  вывода несколько шире отверсти  в печатной плате, благодар  чему выводы упруго устанавливаютс  в печатной плате и не выпадают в процессе монтал-са.orienting the triode and serving as an emphasis when fixing the leads in the printed circuit board 6. The loop of the lead is somewhat wider than the hole in the printed circuit board, whereby the leads are elastically installed in the printed circuit board and do not fall out during the mounting process.

Пилчн   часть петли вывода обеспечивает капилл рность припою 7, а также из-за большой поверхности петли 3, охватываемой припоем , надельный электрический контакт мел«:ду выводом и электрической схемой 8 печатной нлаты.The pilot part of the output loop provides the capillary nature of the solder 7, and also because of the large surface of the loop 3, covered by solder, the endowed electrical contact is chalk “: the output and the electrical circuit 8 of the printed board.

Предмет изобретени Subject invention

Выводы преимущественно дл  маломощных транзисторных триодов, используемые при монтал е их в печатных платах, изготовленные из проволочного материала, отличающиес  тем, что, с целью повышени  производительности и наделчности монтал а, концы твердых выводов изогнуты в виде незамкнутой петли, коротка  часть которой отогнута под пр мым углом в направлении от продольной оси петли .The conclusions are mainly for low-power transistor triodes used in mounting them in printed circuit boards made of wire material, characterized in that, in order to increase the performance and efficiency of montale, the ends of the solid leads are bent in the form of an open loop, the short part of which is bent under from the longitudinal axis of the loop.
