When male and female terminals are fitted and connected, it is known that the male and female terminals are provided with a locking mechanism to ensure the connection with the male terminal and at the same time to prevent the fitting from being accidentally disconnected. FIGS. 7 and 8 show a conventional example of a female terminal having such a locking mechanism, which is described in Japanese Patent Application Laid-Open No. 58-212081. In these figures, A denotes a female terminal, which is made of a conductive plate and has a male terminal receiving part A1 at the front end and a wire connecting part A2 at the rear end. The male terminal receiving part A1 is formed by bending a conductive plate, and includes a bottom plate a, both side walls b, b, and side walls b, b.
It consists of upper plates c and c extending from each tip toward the opposite wall, and is formed in a channel shape. The male terminal receiving part A1 has an elastic tongue piece d which is folded back and connected to the front end of the bottom plate a, and this elastic tongue piece d is divided into three parts by two slits.
Each extends rearward within the male terminal receiving portion A1 . The central part of the divided elastic tongue piece d becomes an elastic contact piece d1 , which extends approximately parallel to the bottom plate a, and a cut-and-raised protrusion e as a locking mechanism is formed in the middle.
The free end is bent upward to form a rising piece f. On the other hand, the pressing pieces d 2 on both sides of the elastic tongue piece d,
d2 is curved into a chevron shape so that the tip g comes into elastic contact with the bottom plate a.

続をする。 The male terminal B is inserted between the upper plate c and the elastic tongue piece d of the female terminal A fitted in the connector housing C, as shown in FIG. When the male terminal B enters a predetermined position, the cut-and-raise protrusion e provided on the elastic contact piece d1 fits into the hole h, which serves as a mating lock mechanism, drilled in the male terminal B, and locks both. . Male terminal B has elasticity of elastic contact piece d 1 and pressing piece d 2
The tip g receives sufficient contact pressure due to the reaction force of pressure contact with the bottom plate a, and presses against the upper plates c, c to establish an electrical connection.

The rising piece f formed at the free end of the connector housing C is pushed down by a lever i provided integrally with the connector housing C, and the cut and raised projection e is removed from the hole h of the male terminal B. Thereafter, the male and female terminals A and B are uncoupled by pulling out the male terminal B or the connector housing C in the opposite direction to when they were fitted.

However, in the above conventional technology, the male terminal B
If the length l 1 is longer than the distance l 2 from the front of the connector housing C to the entire surface of the rising piece f,
The tip of the male terminal B rises and strongly hits the piece f,
The elastic contact piece d1 may be deformed. When the elastic contact piece d1 is deformed, the hole h of the male terminal B and the raised protrusion e cannot be fitted, resulting in a poor connection between the male and female terminals. Moreover, when the elastic tongue piece d deforms, the contact pressure between the male and female terminals A and B decreases, causing poor contact. That is, although the rising piece f is essential for uncoupling, it has the disadvantage that it can cause deformation of the elastic tongue piece d and the elastic contact piece d1 .

In order to achieve the above object, the present invention bends a conductive plate to form a channel-shaped or frame-shaped male terminal receiving part consisting of a bottom plate, both side walls and a top plate,
In the female terminal, the female terminal is provided with an elastic contact piece that is folded back from the front end of the bottom plate and has a locking mechanism with the male terminal in the male terminal receiving part, and the rear end of the top plate is cut and raised into the male terminal receiving part. It is characterized by a structure in which a male terminal blocking piece is formed.

The male terminal is inserted into a male terminal receiving portion formed in the female terminal, is pressed and held by the elasticity of the elastic contact piece, and is locked by the locking mechanism to establish an electrical connection. Even if the male terminal is too long, its tip will come into contact with the male terminal blocking piece bent at the rear end of the upper plate of the male terminal receiving part, so no force will be applied to the elastic contact piece to cause deformation. First, the press-contact parts do not deform, and a reliable electrical connection can be maintained at all times.

A release rod 10 is attached to the connector housing body 9 in advance, and an electric wire 14 is crimped to the wire crimping portion 1b of the female terminal 1. The female terminal 1 inserted from the female terminal insertion opening 11b at the rear of the main body 9 is
First, it comes into contact with the slope on the rear side of the pressing portion 10d. Then, it slides along this slope, bends and lifts the operating part 10c upward together with the pressing part 10d, and runs on the flexible locking piece 9a formed in the main body 9 as it advances. Eventually, the flexible locking piece 9a fits into the locking hole 2a, and the female terminal 1 is locked and fixed at a predetermined position within the main body 9. The pressing part 10d is the operating part 10
Due to its flexibility, the operating portion 10c fits into the recess 4b at the rear end of the upper plate 4, and the operating portion 10c returns to its flat state.

The male terminal 15 enters between the punched out part 4a formed on the upper plate 4 and the elastic contact piece 5b, and the cut and raised projection 6 fits into the hole 15a of the male terminal 15, so that the male and female terminals 1 and 15 are fitted together. Locked. The male terminal 15 has elasticity of the elastic contact piece 5b,
Due to the reaction force of the tips of the pressing pieces 5c, 5c coming into pressure contact with the bottom plate 2, the projecting portion 4a is pressed with sufficient contact pressure and electrically connected.

It turns out. On the other hand, since the free end 5b' of the elastic contact piece 5b is substantially parallel to the bottom plate 2, even if the male terminal 15 is long, it will not receive any harmful force that would cause it to deform. Furthermore, the female terminal 1 is connected to the flexible locking piece 9a and the pressing part 1.
0d will double prevent the vehicle from slipping out of the rear.

できる。 Next, the case of releasing the fitting between the male and female terminals 1 and 15 will be described. In the fitted state shown in FIG. 4, force F is applied to the pressing portion 10d at the tip of the release rod 10. The free end 5b' of the elastic contact piece 5b moves downward, and the cut-and-raised protrusion 6 comes out of the hole 15a of the male terminal 15. At the same time, if a force P is applied to the connector housing 8 (or a force in the direction opposite to P is applied to the male terminal 15), the male and female terminals can be uncoupled from each other.
