Press-fit terminal
First Claim
Patent Images
1. A press-fit terminal adapted to be press-fitted in a through-hole of a board for electrically conducting with the press-fit terminal, comprising:
- a terminal-base portion; and
a board inserting portion extending from the terminal-base portion, the board inserting portion at least partially plated with tin, the board inserting portion defining an elliptical-shaped opening, the board inserting portion including a proximal end closest to the terminal-base portion and a distal end farther from the terminal-base portion, whereina thickness of the plated tin is from 0.1 to 0.8 μ
m to inhibit scraping of the tin on the board inserting portion, anda portion to be plated with the tin is undercoat-plated with nickel to a thickness of from 1 to 1.3 μ
m, whereinthe elliptical-shaped opening is substantially symmetrical in a top and bottom direction, the elliptical-shaped opening extends completely through the board inserting portion, a width of the opening at the distal and proximal ends is less than a width of the opening between the distal and proximal ends, the width of the elliptical-shaped opening at the distal and proximal ends defining a curved base portion of the elliptical-shaped opening.
