Conductive bodies with terminal holes are arranged side by side on the upper and the lower printed boards along peripheral edges of the boards. Press-fit terminals are arranged in row arrangement along the outer peripheral portions of the printed boards. Each of the press-fit terminals is pressed from below into terminal holes of the two upper and lower printed boards with a long first vertical portion outside and a short second vertical portion inside. This results that a press-fit portion of the second vertical portion is pressed and brought into contact with a terminal hole in a conductive body on a peripheral edge of the lower printed board, a press-fit portion of the first vertical portion is pressed and brought into contact with a terminal hole in a conductive body on a peripheral edge of the upper printed board, and a horizontal portion is supported from below by a step-like portion projected from a printed board retaining case.
TECHNICAL FIELD The present invention relates to a press fit terminal, the construction of connecting printed boards to each other by using the press fit terminal, and an electric junction box. More particularly, in the present invention, electric conductors of the printed boards are electrically connected to each other.
BACKGROUND ART As shown in FIG. 13, the electric junction box 1 proposed in Japanese Patent Application Laid-Open No. 7-297562 accommodates the first printed board 5 and the second printed board 6 in the box composed of the upper case 2 and the lower case 3, with the insulating sheet 4 interposed between the upper case 2 and the lower case 3. Terminal holes 5 a and 6 a are formed on the first printed board 5 and the second printed board 6 respectively. Connection pins 7 are inserted through the terminal holes 5 a and 6 a and soldered thereto.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an electric junction box of the first embodiment of the present invention, in which (A) is a plan view and (B) is a bottom view.
FIG. 2 is a sectional view of the electric junction box of the first embodiment taken along a line I�I.
EXPLANATION OF REFERENCE NUMERALS AND SYMBOLS 10: electric junction box
BEST MODE FOR CARRYING OUT THE INVENTION The embodiments of the present invention will be described below with reference to drawings.
As shown in FIG. 4, the terminal hole 31 b formed on the electric conductor 31 a of the first printed board 31 is copper plated on an entire inner peripheral surface of the terminal hole 31 b and on the surface of the printed board 31. The copper plated surface of the first printed board 31 is tin plated or solder plated to form a conductive layer 31 c. An upper portion of the conductive layer 31 c is joined with the electric conductor 31 a. The terminal holes 32 b and 33 b of the second and third printed boards 32 and 33 have a construction respectively similar to that of the terminal hole 31 b. As shown in FIG. 5, the press fit terminal 20 connecting the electric conductor 31 a of the first printed board 31 and the electric conductor 32 a of the second printed board 32 to each other and the press fit terminal 20 connecting the electric conductor 32 a of the second printed board 32 and the electric conductor 33 a of the third printed board 33 to each other are formed by bending a rod-shaped material made of conductive metal. The press fit terminal 20 has a long first vertical part 21, a horizontal part 22 bent at a lower end of the first vertical part 21, and a short second vertical part 23 bent upward at a leading end of the horizontal part 22. Press fit parts 24, 25 are formed at a leading end of the first vertical part 21 and at a leading end of the second vertical part 23 respectively. The press fit parts 24, 25 are shaped rhombically by striking the center thereof in the widthwise direction thereof to thin the center thereof so that the center thereof can be decreased in its diameter and by bending right and left side portions thereof outward in the shape of a letter �<�. The leading end of each of the press fit parts 24, 25 decreases taperingly in the diameter thereof.
