If a displacement of . For example, the third
In the figure, reference numeral 11 indicates a connector housing made of plastic, and reference numeral 12 indicates a tab-shaped electrical contact piece of the mating male electrical connector. Although the insertion position of the electrical contact piece 12 is regulated by the connector housing 11, Since it is a molded product, if excessive force is applied, the insertion opening for the electrical contact piece 12 may be deformed, and the electrical contact piece 12 may be inserted into a place other than its intended location, resulting in poor contact. Furthermore, as shown in FIG. 4, even when the electric contact piece 12 is inserted in the normal position, if excessive displacement is applied, the movable contact piece 5 exceeds its elastic limit, and the electric contact piece 12 returns to the normal position. However, there is a problem in that the elastic force of the movable contact piece 5 weakens, resulting in poor contact.

不良を起こすことがなくなる。(Function) By using a female type electrical connector with the above structure, even if the electrical contact piece 12 of the mating male type electrical connector is inserted into a place other than its intended purpose as shown in FIG. The insertion opening is narrowed by a curved part formed by folding back the tips of both side walls of the contact piece fitting part, and the insertion opening is blocked by this curved part and does not enter a place other than the above purpose. Even if the electric contact piece 12 is inserted to force the movable contact piece as shown in Figure 4, the tip of the movable contact piece is suppressed by the tongue piece, preventing abnormal deflection and restoring the movable contact piece without exceeding its elastic limit. Therefore, the electric contact piece 12 is elastically held between the movable contact piece 5 and no contact failure occurs.

FIG. 3 is a cutaway cross-sectional view of the contact piece fitting portion. In these figures, 2 and 3 are a pair of conductor clamping pieces and an insulating coating clamping piece, respectively, similar to the conventional example. On both side walls 4 of the contact piece fitting part 1, as in the conventional example,
A pair of movable contact pieces 5 are provided facing each other, and a curved portion 6 is formed to have elasticity. The projecting pieces formed at the open ends of both side walls 4 of the contact piece fitting part 1 are folded back inward through the curved part 8 so that the tip part 9 extends further back than the free end edge 7 of the movable contact piece 5. A pair of extending tongue pieces 10 are provided. 1st
As is clear from the figure, the tip opening of the contact piece fitting part 1 is narrowed by the curved part 8 of the tongue piece 10, and even if the mating tab-shaped electric contact piece is inserted obliquely, Even if the movable contact piece 5 is pried by the other tab-shaped electric contact piece, the tip 7 will not be blocked by the curved part 8 and will not get between the movable contact piece 5 and the tongue piece 10. Tongue piece 1
0 prevents abnormal deflection and does not exceed the elastic limit, so the mating tab-shaped electrical contact piece is sufficiently elastically held by the movable contact piece 5 and no contact failure occurs.
