生ずる。However, in the conventional case, the box-shaped main body has a weak shape-retaining strength because it has a structure in which the metal plate is bent and the edges are simply abutted against each other to form the box. There was a problem. For this reason,
When the terminal fittings are transported in the connector assembling process or when the terminal fittings are handled in the assembling process, the box-shaped main body portion is likely to be deformed when a little large force is applied. If such deformation occurs, it may be difficult to mount it on the female connector housing, or the connection with the male terminal fitting may become unstable, so such terminal fitting is excluded as a defective product. It has to be done, and waste occurs.

容される。Then, when each female terminal fitting A is inserted into each cavity 52 of the connector housing 50 through the opening 56 on the rear surface with the lance 5 facing the upper surface side, the locking portion 54 on the upper surface of the cavity 52 accommodates the lance. It is relatively fitted into the fitting groove 14 of the bottom plate 13 of the chamber 6, and as shown in the upper female terminal metal fitting A, the lance 5 abuts on the locking portion 54 and the protrusion 21 on the side edge at the tip thereof. To the window hole 44 of the right side plate 25
It is elastically bent downward while moving inside. further,
When the female terminal fitting A is pushed in and the lance 5 passes through the locking portion 54, as shown in the female terminal fitting A in the lower stage, the lance 5 is returned to the original position by the resilience and is forward of the locking portion 54. , And the female terminal fitting A is housed in the cavity 52 so as not to come off.

よりそれが阻止される。Thereafter, a retainer (not shown) is inserted from the retainer insertion port 55 on the lower surface of the connector housing 50, and the retainer is locked to the rear surface of the connection piece accommodating chamber 4 in the insertion direction, so that the female terminal metal fitting A is doubled. Locked in. And
When the mating male side terminal is inserted from the terminal insertion hole 53 on the front surface of each cavity 52, the tab portion of the male side terminal enters into the connecting piece accommodating chamber 4 and bends the connecting piece 3 flatly. It is inserted and both terminal fittings are connected. At that time, if the connecting piece 3 tries to bend excessively, for example, when the male-side terminal is inserted at an angle, the excessive bending-preventing piece 36 hits the connecting piece 3 to prevent it.

難になる事態が確実に防止される。As described above, in the female terminal fitting A of this embodiment, since the connection piece 3 and the lance 5 are housed in the box-shaped connection piece storage chamber 4 and the lance storage chamber 6, respectively, the connection piece 3 is connected.
The lance 5 is protected from inadvertently interfering with external devices. Moreover, the accommodating chambers 4 and 6 are provided at the first and right side edges of the bottom plate 32 and the upper plate 17, respectively.
And the second plugs 20 and 40 on the common right side plate 25
Since it is inserted into the second fitting holes 41, 42 and formed into a box shape, the shape holding strength is high. Therefore, there is no risk that the box will be crushed and deformed during transportation or when it is attached to the connector housing 50, and the connection piece 3 and the lance 5 can be reliably prevented from being deformed due to the deformation of the box. It is possible to surely prevent the situation where the fitting of the terminal fitting on the male side becomes uncertain due to the deformation of the box and the mounting to the connector housing 50 becomes difficult.

Since the entire rear surface can be used, the female terminal fitting A can be more reliably prevented from coming off. At the same time, the female terminal fittings A are assembled into a compact one that is short in the lengthwise direction, and the connector housing 50 can be correspondingly made compact.

Is reliably prevented. For this reason,
For example, in order to pull out the female terminal fitting A from the connector housing 50 for repair or inspection, when the tip of the jig is applied to the lance 5 to bend it, the lance 5 is excessively bent and plastically deformed. It is surely prevented.
