Stem and its manufacture

Abstract

Abstract PURPOSE:To reduce parts in number by protruding a lead frame from one side surface of a header and folding it at its middle part allowing terminal part of each lead of the frame to face the circuit-element fitting part closely and the other terminal to protrude toward the side over the head. CONSTITUTION:A copper plate with a thick part and thin part is punched to form thick header part 14 and thin lead frame part 15. In this case, header part 14 is shaped in a square and fitting grooves 16 are provide to center parts of both edges; and two-step support part 17 extending upward is formed at one side of this groove 16 and junction cut-in groove 18 with frame part 15 is formed at its tip. On the other hand, thick link part 19 is elongated from the opposite side to support part 17 encircling fitting groove 16 of header part 14 and its tip is connected to internal frame 20 of frame part 15. Further, longitudinal frame 22 of frame part 15 is provided with alternative path 25 protruding from header part 14 and each lead 23 is curved as it approches the internal frame with its tip made to face the center part of the frame.
