Claims

[Scope of utility model registration request]

(1) A female contact for an electrical connector for a printed wiring board, characterized in that the contact portion is shaped like a ship's bottom with the tip located on the insertion side of the printed wiring board.

(2) Utility Model Registration Claim Claim 1: The female contact of an electrical connector for a printed wiring board, wherein a hill portion for guiding the printed wiring board is provided at the front part of the bottom-shaped contact part, which is lower than the height of the contact part.
