Female terminal fitting
View Patent ↗A female terminal fitting includes terminal holding plates stacked on one another are configured of a basic terminal holding plate formed integrally with one end of an electric wire connecting portion and auxiliary terminal holding plates which are formed on corresponding edges of the basic terminal holding plate via corresponding bending margins and which are folded up and then down on to the basic terminal holding plate so that the auxiliary terminal holding plates are in a stacked state on the basic terminal holding plate. A fixing piece is formed integrally on an auxiliary terminal holding plate which is stacked at an uppermost level at an edge portion on a side which lies opposite to a side where the bending margin is provided, so as to be brought into engagement with a locking portion on the basic terminal holding plate to fix the stacked state.
1. A female terminal fitting comprising:
a terminal connecting portion which is formed by stacking a plurality of metallic terminal holding plates on one another and which enables a plate-shaped mating terminal fitting to be inserted into terminal holding grooves which are respectively formed in the terminal holding plates so as to communicate with one another; and
an electric wire connecting portion which is provided so as to continue to the terminal connecting portion and to which an electric wire is connected, wherein
the plurality of terminal holding plates are configured of a basic terminal holding plate which is formed integrally with one end of the electric wire connecting portion, and a plurality of auxiliary terminal holding plates which are formed integrally with corresponding edges of the basic terminal holding plate via corresponding bending margins and which are folded up and then down on to the basic terminal holding plate at portions where the bending margins are provided so that the auxiliary terminal holding plates are in a stacked state on the basic terminal holding plate, and
on an auxiliary terminal holding plate in the plurality of auxiliary terminal holding plates which is stacked to be at an uppermost level, a fixing piece is formed integrally with an edge portion at a side which lies opposite to a side where the bending margin is provided, the fixing portion being configured so as to be brought into engagement with a locking portion which is formed on the basic terminal holding plate in such a state that the auxiliary terminal holding plate which is to be stacked at the uppermost level is so stacked as an uppermost layer to fix the plurality of auxiliary terminal holding plates which are stacked on one another.
2. The female terminal fitting according to claim 1 , wherein
the terminal holding grooves include
terminal insertion grooves into which the mating terminal fitting can be inserted and
contact portions which are provided on facing inner side surfaces of the terminal insertion grooves so as to project therefrom for press contact with surfaces of the mating terminal fitting which is inserted into the terminal insertion grooves, and
in the stacked state of the plurality of terminal holding plates, the plurality of contact portions are formed in positions which are offset from each other in an inserting direction of the mating terminal fitting.
3. The female terminal fitting according to claim 1 , wherein
the electric wire connecting portion comprises
an electric wire placement plate portion which is made of a metallic plate and which extends from a proximal end of the basic terminal holding plate to place the electric wire thereon and
crimping pieces which are provided on both side edges of the electric wire placement plate portion so as to extend therefrom to be crimped to the electric wire which is placed on the electric wire placement plate portion.
