Contact pin with solder tag for circuit board - has slit in underside of tag with varying width for reception and retention of liq. solder

摘要

The contact portion (1) is built up on a base (11) under which the solder tag, pushed into a hole through the board (2), is divided by a slit (101) into two symmetrical parts (10A,10B). Recesses (106A,106B) in these form a chamber into which the solder is drawn. The hole has a dia. slightly less than the max. dia. of the tag at the level (107A,107B) from which the slit (101) tapers in opposite directions (103,104) downwards and upwards. ADVANTAGE - Pin is easily inserted by machine without delamination at holes, and improves solder flow by capillarity.
