Problems solved by technology

That is, since the base end of the elastic contact piece is folded back and is closely supported, the base end of the elastic contact piece may be plastically deformed.
If the male terminal on the opposite side is repeatedly inserted into and pulled out from the inside of the connecting terminal part of the female terminal, cracks may occur in the close-fitting bending part of the elastic contact piece.

Embodiment Construction

[0029] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0030] [Structure of female terminal]

[0031] First, the structure of a female terminal according to one embodiment of the present invention will be described.

[0032] (the whole frame)

[0033] refer to Figures 1 to 6A , Figure 6B , The female terminal 10 according to one embodiment of the present invention has a square tube-shaped connection terminal portion 1 and a connection portion 2 . The connection terminal part 1 can introduce a blade-shaped male terminal (not shown) from the opening of the connection terminal part 1 of the female terminal 10 . The terminal part 2 can connect the terminal of the electric wire W.

[0034] A waterproof cover 3 made of rubber is attached to the terminal of the electric wire W. As shown in FIG. According to such a structure, when the female terminal 10 is mounted in the cavity of the unillustrated plug housing, the...

Abstract

A female terminal capable of suppressing damage to an elastic contact piece. The female terminal (10) has a connection terminal portion that houses an elastic contact piece (17). The connection terminal portion is formed in a square tube shape surrounded by a bottom plate (11), a pair of side plates (12, 13), and a set of a first upper panel (14) and a second upper panel (15). The connection terminal portion further includes a band-shaped connection piece connected to a part of the elastic contact piece. The connecting piece is formed as a part of one side plate. The connecting piece has: oneend portion which is bent in accordance with a bent portion between one side plate and the first upper plate; and the other end portion which is bent in accordance with a bent portion between one sideplate and a bottom plate and is in elastic contact with the base ends of the sheets. The elastic contact piece has a portion inclined upward toward the inner wall of the second upper panel, and is disposed inside the connection terminal portion. Since the base end portion (17a) of the elastic contact piece does not include a structure that is closely bent, it is possible to suppress damage to theelastic contact piece.

Description

technical field [0001] The present invention relates to female terminals. In particular, it relates to a female terminal having a connecting terminal portion electrically connected to a male terminal on the distal end side and a female terminal having a connection portion to which an electric wire can be connected on the base end side. Background technique [0002] For example, the female terminal has a square cylindrical connection terminal portion electrically connected to the male terminal on the distal end side, and has a connection portion to which electric wires are connected on the base end side. Furthermore, in such a female terminal, a connection terminal portion and a connection portion are molded by bending a developed plate made of a conductive metal plate. [0003] The connection terminal portion of such a female terminal is formed in a square tube shape. The square tube-shaped structure is surrounded by, for example, a strip-shaped bottom plate, a pair of sid...
