Problems solved by technology

[0006] Because the above-mentioned conventional press-fit type connector terminal is designed to have an outer diameter larger than the inner diameter of a through-hole formed through a printed circuit board, and has a press-fit portion with low elasticity to be inserted into the through-hole to come into contact with the through-hole , so the printed circuit board is prone to whitening due to the contact pressure exerted by the press-fit part on the through hole, and the plating layer of the through hole is sometimes peeled off
Because the whitening of the printed circuit board means the molecular destruction of the components constituting the board, the molecular destruction not only causes the deterioration of the electrical insulation of the printed circuit board and the deterioration of the withstand voltage, but also causes an increase in the resistance of the circuit pattern

Abstract

The press-fit type connector terminal includes a pin section having a U-shaped or quadrangular cross-section, and a contact section situated at a front end of the pin section. The contact section includes a contact piece surrounding an imaginary center line parallel to a longitudinal axis of the pin section, and a slit formed at a part of the contact piece and extending substantially parallel to the imaginary center line. The connector terminal is comprised of a single bent metal plate having elasticity.

Description

technical field [0001] The present invention relates to a press-fit type connector terminal to be inserted into a conductive via hole formed through a printed circuit board. Background technique [0002] Various press-fit type connector terminals have been proposed. For example, they have a terminal contact portion having a cross-section in the shape of an eye of a needle, a C-shape, an N-shape, or a Σ-shape. [0003] Japanese Patent Application Publication No. 2004-134275 has proposed a connection terminal including a head to which a cable is connected and a body to be inserted into a through-hole formed through a substrate. The main body is formed at the center with a hole extending in the lengthwise direction thereof, and the hole is formed with a plurality of slits extending from the inner wall of the main body to the outer wall. The hole is filled with conductive adhesive. [0004] Japanese Patent Application Publication No. 2007-157469 has proposed a press-fit type ...
