In this female terminal fitting 10, by providing a plurality of striking portions 29 parallel to the slit 20 on both sides of the slit 20 of the tuning fork terminal 18, the rigidity of the tuning fork terminal portion 15 can be increased, and after punching molding, It is possible to prevent the tuning fork terminal 18 from being deformed when the reel is wound.
[0044]
【The invention's effect】
As apparent from the above description, according to the invention of claim 1, since the tuning fork terminal portion is provided with the deformation preventing means for preventing the deformation of the tuning fork terminal, the deformation preventing means can be used to wind the reel after punching. The deformation of the tuning fork terminal at the time can be prevented.
[0045]
According to a second aspect of the present invention, the deformation preventing means is formed by a pair of L-shaped bent walls extending from the tuning fork terminal portion toward the bottom wall. Since the portion is formed integrally with the bottom wall, it is possible to increase the rigidity of the tuning fork terminal portion and to prevent the tuning fork terminal from being deformed when winding the reel after punching.
[0046]
According to the invention of claim 3, since the deformation preventing means is formed by a punched portion provided in the tuning fork terminal, the rigidity of the tuning fork terminal portion can be increased, and the tuning fork terminal at the time of winding the reel after punching molding Can be prevented from being deformed.
