Claims (3)

A flat plate formed in a flat plate shape from the press-fitting portion fixed by press-fitting to the connector housing to the tip of the mating terminal connecting portion connected to the elastic contact piece provided in the square tubular connecting portion of the female terminal which is the mating connection terminal. A base portion, a ridge portion formed on the surface of the flat plate base portion on the side to which the elastic contact piece is connected from the press-fitting portion to the periphery of the tip, and a ridge portion serving as a portion to which the elastic contact piece is contacted.
A male terminal characterized by having. From both sides of the flat plate base from the press-fitting portion to the periphery of the tip, the elastic contact piece is bent to the back surface side with respect to the surface to which the elastic contact piece is connected, and then bent back to the front surface side to bend in a U shape. It has a pair of reinforcing walls raised at a height that allows it to be inserted into the square tubular connection.
The pair of reinforcing walls are inserted between the inner wall surface of the cylinder facing the elastic contact piece in the width direction of the square tubular connection portion and both side surfaces of the elastic contact piece, whereby the elastic contact piece is reinforced by the pair. The male terminal according to claim 1, wherein the male terminal is brought into contact with the ridge portion between the walls. From both sides of the flat plate base from the press-fitting portion to the periphery of the tip, the elastic contact piece is bent in an L shape toward the surface side to which the elastic contact piece is connected, and stands at a height that can be inserted into the square tubular connecting portion. With a pair of raised reinforcing walls,
The pair of reinforcing walls are inserted between the inner wall surface of the cylinder facing the elastic contact piece in the width direction of the square tubular connection portion and both side surfaces of the elastic contact piece, whereby the elastic contact piece is reinforced by the pair. The male terminal according to claim 1, wherein the male terminal is brought into contact with the ridge portion between the walls.
