Shown in The female terminal 10 of this conventional example has a cylindrical fitting portion 11 that can be fitted to the tab 1 at the tip of the male terminal, and is folded back in a mountain-like manner from the tip portion 13 of the bottom surface 12 of the fitting portion 11. The tongue 14 is provided, and the tab 1 is sandwiched between an emboss 16 formed inward from the ceiling 15 of the fitting portion 11 and a top 17 of the tongue 14.

ジン自体の振動などにより、雄端子と雌端子の接触位置
がずれる。Incidentally, in a small terminal used in a minute current circuit, the contact position between the tab of the male terminal and the female terminal may change due to external factors such as vibration. For example, in the case of a connector for an automobile, the contact position between the male terminal and the female terminal is shifted due to vibration of the engine itself.

が高いという問題点を有していた。On the other hand, since the surface of the contact portion between the male terminal and the female terminal is gas-tight, oxidation by oxygen in the air is suppressed, but the oxidation of the other surface proceeds with time. Therefore, if the contact position between the male terminal and the female terminal shifts as described above, the original contact portions of the male terminal and the female terminal come into contact with the portions where the oxide film is formed, respectively. There is a problem that the possibility of causing a defect (non-conduction) is high.

接触圧力が得られないという問題点を有していた。When a large number of terminals are arranged at a minute pitch, such as a flat cable connector, a sufficient contact pressure can be obtained because the thickness of the terminal material is small and the width of the tongue is small. There was no problem.

It is an object. It is another object of the present invention to provide a terminal structure capable of securing a sufficient contact pressure even when a large number of terminals are arranged at a minute pitch.

The tab 200 of the male terminal may be
If, for example, a force A as shown by a rightward arrow A is applied, the tongue 1
20 is to be displaced in the direction of arrow A in FIG. At this time, a frictional force μF acts on each contact point between the second contact portion 123 and the bottom surface 112 and the ceiling surface 113 of the fitting portion 110 in a direction opposite to the arrow A. When the total frictional force 2 μF acting on the tongue piece 120 is larger than the force A applied to the tab 200, the tongue piece 120 is not deformed, and the tab 200 moves between the tongue piece 120 and the ceiling surface 113 of the fitting portion 110. It cannot be moved while being pinched, or is restrained so that the amount of movement is small.

The contact positions of the tongue piece 120 and the fitting part 110 of the female terminal 100 do not shift, and the original contact parts of the tab 200 of the male terminal and the tongue piece 120 of the female terminal 100 and the ceiling surface 113 of the fitting part 110 are oxide films, respectively. There is no possibility of contact with the portion where the contact is formed, and there is almost no possibility of causing an increase in contact resistance or poor contact (non-conduction).

When the male terminal conductor is fitted, a force acts on the male terminal conductor due to vibration or the like in a state where the male terminal conductor is fitted, and even if the tongue is displaced, the male terminal conductor is fitted with the second contact portion of the tongue. The tongue is not displaced by the frictional force acting between the tongue and the inner peripheral surface of the mating portion, so that the displacement of the tongue is reduced, and the contact positions of the tongue and the fitting portion of the male and female terminals are shifted. And the original contact portions of the male and female terminals do not contact or reduce the possibility of contact with the oxide film formed portions Is, increase in contact resistance and contact failure can cause (non-conductive) is almost eliminated or reduced. Also, when a large number of terminals are arranged at a minute pitch, such as a flat cable connector, the spring constant substantially increases even if the thickness of the terminal material is reduced and the width of the tongue is reduced. Therefore, it is possible to obtain a sufficient contact pressure.
