くなどの問題点があつた。 Conventionally, a Faststone type terminal as shown in FIG. 1 has been generally used as a female terminal for large current. That is, the Faston type terminal F has an electrical contact part c in the front half, which is formed by curving both side extensions of the board a onto the board a to form an arch-shaped elastic piece b, and a rear part for the electric wire crimping. Piece b and covered wire crimping piece e
However, in such a terminal, when a large current is applied to the terminal, the elastic piece b
is heated to a high temperature and causes a creep phenomenon, that is, so-called high-temperature creep, which causes the elastic piece b to bend and maintain a sufficient contact load with a mating terminal (not shown) inserted into the electrical contact part c. In addition to making contact difficult and causing poor contact, contact resistance increases and the terminal is heated to a higher temperature, reducing the insulation properties of the housing and eventually igniting the housing, resulting in a fire hazard. Ta.

ものである。 The present invention improves the drawbacks of such conventional terminals, and
To provide a terminal that maintains sufficient contact load with a mating terminal and does not cause contact failure or increase in contact resistance even when a large current is applied and the elastic piece of the electrical contact part is slightly bent due to high temperature creep. It has been done.

部９の近傍に屈折部８が形成される。 In the figure, the female terminal A of the present invention is made of a terminal board 1 made of a material with good elasticity such as phosphor bronze or brass, with extending portions on both sides erected on both sides of the board 1 to form side walls 2. Further, the extending portions of the side wall 2 are bent inwardly in parallel with the substrate 1 to form the upper wall 3, and the front end extending portions of the side wall 2 are further bent inwardly to form an elastic electrical contact piece. A box-shaped electrical contact part A 1 having a structure in which a wire crimping part 4 is formed is provided in the front half, and a conductor crimping part consisting of a wire crimping part 5 and a covered wire crimping part 6 is provided.
The terminal of the present invention has an improved structure of the electrical contact piece 4 and the side wall 2 of the box-shaped electrical contact part A1 . That is, as is clear from FIG. 3, the elastic electrical contact piece 4 has the front ends of the side walls 2 bent inward and extended, and a chevron-shaped bent part 7 with opposing tops formed in the central part. Furthermore, the free ends 9 of the electrical contact pieces 4 are each oriented in the direction of the central axis of the terminal, and a bent portion 8 is formed near the free ends 9.

形成される。 Therefore, when the electrical contact piece 10 of the mating male terminal B is inserted into the electrical contact part A1 of the female terminal A, the electrical contact piece 4 is bent to the position shown by the dotted line, and the chevron-shaped bent part 7 is bent to the position shown by the dotted line. A first contact 11 is provided between the electric contact piece 10 and the free end tip 12 of the electric contact piece 4 is configured to have a second contact 13. The bent portion 8 formed near the free end portion 9 bends over the side wall 2 when the electrical contact piece 10 of the male terminal B is inserted into the electrical contact portion A1 of the female terminal A.
It is formed at a position where it comes into contact with the constriction part 14 formed at the rear of the.

斜辺部である。 Note that the narrowed portion 14 is an oblique portion formed on the side wall 2 leading to the conductor crimping portion A 2 narrower than the width of the box-shaped electrical contact portion A 1 .
次に本考案の端子の作用を第３図について説明
する。 Next, the operation of the terminal of the present invention will be explained with reference to FIG.

全に防止される。 When the electric contact piece 10 of the male terminal B is inserted between the electric contact pieces 4 of the female terminal A, the electric contact piece 4 is bent to the position shown by the dotted line, and the tip of the electric contact piece 4 moves in the direction of arrow C. do. At this time, the bent part 8 formed near the free end part 9 of the electrical contact piece 4 is pushed to the position 8' and comes into contact with the constricted part 14 formed at the rear of the side wall 2, so that the electrical contact of the male terminal B is made. The tip 12 of the free end 9 that contacts the piece 10 moves to the position 12' and a contact load is applied thereto. Therefore, the bent portion 7 of the electrical contact piece 4 is slightly bent due to high temperature creep, and even if the contact load of the first contact 11 decreases, the contact load of the second contact 13 increases, resulting in poor contact with the male terminal B. is completely prevented.

供することができる。 Since the terminal of the present invention is constructed as described above, even if a large current is applied and high temperature creep occurs in the electrical contact piece and the electrical contact piece is slightly bent, a sufficient contact load can be maintained at the tip of the electric contact piece. It is possible to provide a safe terminal that does not cause poor contact or increase in electrical resistance.
