An external force that causes micro-sliding of about μm) may act. On the other hand, in the tab portion 210, an oxide film is formed with time on the surface of the portion other than the portion in contact with the spring contact portion 320. In such a situation, if the above-mentioned fine sliding occurs in the contact portion, the contact position of the tab portion 210 with respect to the spring contact portion 320 shifts and changes, and as a result, poor conduction due to the presence of the oxide film. May be caused. In addition, abrasion powder may be generated due to rubbing caused by the relative fine sliding.

これを実現させたものである。In order to achieve the above-mentioned object, the present invention provides a method in which a tab portion of a contact portion and a spring contact portion are connected to each other even when an external force which causes slight sliding is applied. Focusing on the fact that it is sufficient to finely move together while maintaining the same contact state without causing relative displacement, this is realized particularly in the width direction.

A male terminal having a tab portion to be brought into contact with the male terminal, wherein a convex portion is formed in the spring contact portion, and a concave groove in which the convex portion can fit into the tab portion of the male terminal is formed. The concave groove is formed so as to extend in the terminal insertion direction, and the concave groove allows the relative movement between the spring contact portion and the tab portion in the insertion direction in a state where the convex portion is fitted in the concave groove. It is formed so as to block in the groove width direction of the groove.

Means that the tab portion can be further advanced in the insertion direction to achieve the contact connection between the male terminal and the female terminal, while the relative movement between the tab portion and the spring contact portion is prevented in the groove width direction of the concave groove. It will be in the state that was done. For this reason, even if an external force is applied to relatively finely slide the tab portion and the spring contact portion, the tab portion and the spring contact portion will slightly move together,
Both maintain the same contact state without relative movement. As a result, it is possible to prevent the occurrence of a conduction failure due to a change in the contact position, and to maintain the initially good conduction state. In addition, since the concave groove extends in the insertion direction, the concave groove serves as an insertion direction guide for the convex portion, and is reliably linearly guided when the tab portion is inserted, so that both ends of the male and female members are provided. The work of joining the children can be performed reliably.

And the combination of the "groove" of the tab portion is any shape as long as the relative movement between the tab portion and the spring contact portion in the groove width direction can be prevented in a state where the convex portion is fitted in the concave groove. A combination of cross-sectional shapes may be used. For example, a combination of a convex portion having a triangular or quadrangular cross-sectional shape and a corresponding groove having a triangular or quadrangular cross-sectional shape corresponding thereto may be used. Preferably, the convex portion may be formed in a hemispherical shape, and the concave groove may be formed in such a manner that the cross-sectional shape in the groove width direction becomes a semicircular shape. In this case, the tab portion can be smoothly inserted into the fitting portion, and the contact between the tab portion and the spring contact portion can be made stable and reliable, so that the reliability of the electrical connection can be improved. . The effect of smooth insertion and stable contact can be achieved by forming the concave groove and the convex portion such that the radius of curvature of the cross section of the concave groove is slightly larger than the radius of curvature of the convex portion. Further enhanced.

When inserted and pushed into the mating portion 31 (see the state shown by a dashed line in the figure), first, the convex portion 33 is fitted into the concave groove 22, and the spring contact portion 32 is shown by a solid line in FIG. It is elastically deformed from the state to the state shown by the dashed line. Thereafter, the tab portion 21 is guided in a straight line by the concave groove 22 and inserted to the back, and the tab portion 21 is sandwiched between the spring contact portion 32 and the wall surface of the fitting portion 31 facing the spring contact portion 32. In this state, while receiving the pinching force based on the elastic restoring force from the spring contact portion 32, the tab portion 21 makes contact between the convex portion 33 and the concave groove 22 and between the tab portion 21 and the wall surface of the fitting portion 31. The contact makes it possible to obtain strong contact conduction with the female terminal 3. In addition, even if an external force acts to slightly slide each other in the groove width direction from one or both of the male terminal 2 and the female terminal 3, even if an external force acts,
The tab portion 21 and the spring contact portion 32 move together without being displaced in the groove width direction due to the relative movement prevention of 3 in the groove width direction. Thereby, the contact state between the tab portion 21 and the spring contact portion 32 can be maintained in the same state as when the insertion is completed, and the occurrence of the conduction failure due to the above-described displacement can be reliably avoided.
