た状態でランス５３により脱抜不能に装着される。2. Description of the Related Art FIG. 4 shows an example of a female connector for a connector which is mounted on a connector and connected to a male connector of a mating connector. This female terminal fitting 40
Is formed by bending and assembling a metal plate material punched into a predetermined shape, and has a cylindrical fitting portion 41 having a distal end opened as a fitting inlet 42. Inside the cylindrical fitting portion 41, a portion elongated from the distal end of the lower wall plate 43 constituting the cylindrical fitting portion 41 is bent backward to form a folded portion 4.
An elastic contact piece 45 provided with elasticity by 5a is provided. The female terminal fitting 40 is inserted from the rear into a cavity 51 formed in the connector 50,
The lance 53 is attached so as not to be detachable with the lance 53 aligned with the connection port 52 opened at the tip of the connector 50.

電気的に接続される状態となる。When the female terminal fitting 40 mounted on the connector 50 and the male terminal fitting mounted on the mating connector (not shown) are connected in this manner, the tab 55 projecting from the tip of the male terminal fitting is connected to the connector 55 by a tab 55. 50 through the connection port 52 and the fitting port 42 of the female terminal fitting 40 in order.
4 and is pinched between the upper surface in FIG. 4 and the upper wall surface 46 of the cylindrical fitting portion 41 by the elastic force of the elastic contact piece 45, so that the male terminal fitting and the female terminal fitting 40 are securely connected. Is electrically connected to the terminal.

具と雌端子金具４０との接触が確実に行われなくなる。In the above connection means, the connection port 52 of the connector 50 has a large opening so that the tab 55 of the male terminal fitting can be inserted and withdrawn.
Reference numeral 2 denotes an opening that is larger than the connection port 52 over substantially the entire distal end surface of the cylindrical fitting portion 41. For this reason, a foreign substance having a greater thickness than the tab 55, such as the tip of a screwdriver, is inserted into the cylindrical fitting portion 41 from the connection port 52, or the tab 55 is inserted obliquely as shown in FIG. Sometimes.
In such a case, the folded portion 45a of the elastic contact piece 45 is excessively bent beyond its elastic limit, and the excessive bending causes settling and loss of proper spring characteristics. When proper spring characteristics are lost in this way, it becomes impossible to squeeze the tab 55 into which the elastic contact piece 45 is correctly inserted between the tab 55 and the upper wall surface 46 at a predetermined contact pressure. Contact with the terminal fitting 40 is not reliably performed.

するようになっている。Therefore, in order to prevent the proper spring characteristics of the elastic contact piece 45 from being lost, a part of the lower wall plate 43 of the cylindrical fitting portion 41 is conventionally bent upward to form a tip. A stopper 48 facing the lower surface of the elastic contact piece 45 is provided. When the elastic contact piece 45 is elastically deformed, the lower surface of the elastic contact piece 45 comes into contact with the tip of the stopper 48 before the amount of deflection exceeds the elastic limit. The above elastic deformation is prevented, and excessive bending exceeding the elastic limit is prevented, so that the appropriate spring characteristics of the elastic contact piece 45 are maintained, and the male terminal fitting and the female terminal fitting 40 are surely brought into contact with each other. It has become.

ズな挿入がなされなくなってしまう。However, the conventional method of providing the stopper 48 as described above to prevent the excessive bending of the elastic contact piece 45 has the following problems. That is, when a foreign object is inserted with a large force, the stopper 48 is tilted against the pressing force from the elastic contact piece 45 side to be damaged, or the elastic contact piece 45 made of a thin plate is damaged.
Bends. In particular, in the case of the small female terminal fitting 40, such a problem is likely to occur because the thickness of the plate material used is small. For this reason, the elastic contact piece 45 is set and loses proper spring characteristics, and smooth insertion is not performed.

子金具１０の電気的な接触は確実なものとなる。Here, when the tab 9 is fitted in a state of being largely obliquely inclined from the connection port 5, the tip of the tab 9 abuts on the bent plate portion 20 to prevent its intrusion. When the tip of the tab 9 is inserted into the insertion hole 21 even when the tab 9 is inserted in an inclined state, the path of the tab 9 is formed at two places, the connection port 5 of the connector housing 2 and the insertion hole 21 of the cylindrical fitting portion 12. Therefore, by penetrating both the connection port 5 and the insertion hole 21, the fitting direction is corrected so as to be a correct direction. As a result, it is possible to prevent the tab 9 from abutting on the extension 16B at a large angle in a state of being inclined and causing the tab 16 to bend into the folded portion 16A. Therefore, the proper spring characteristics of the elastic contact piece 16 are not lost, and the elastic contact piece 16
And the tab 9 contact with a predetermined contact pressure, and the electrical contact between the male terminal fitting and the female terminal fitting 10 is ensured.

Therefore, a situation in which the elastic contact piece 16 is excessively bent beyond its elastic limit due to the intrusion of a foreign substance larger than the tab 9 is avoided, whereby the proper spring characteristic of the elastic contact piece 16 is lost. Is prevented.

を得ることができる。When the female terminal fitting 30 and the male terminal fitting of the second embodiment are connected, the tabs of the male terminal fitting are connected to the connection port of the connector housing (not shown) and the fitting port 37 of the cylindrical fitting section 32. , Passing through the regulating member 36 in order, and
After being clamped between the contact portion 35 </ b> C of No. 5 and the upper wall plate 33, it is fitted into the auxiliary regulating member 31. While the tab is inserted, the insertion direction of the tab is corrected by the restricting member 36, and the tip of the tab 9 is finely corrected by the auxiliary restricting member 31 to press the tab 9 against the wall plate 33B. 35 can be reduced. In particular, even when vibration is applied to the connector, the amplitude of the vertical movement of the tip of the tab 9 is regulated, so that stable electrical contact can be obtained.
