The terminal fitting portion 21 includes a bottom plate 23 in which the electric wire connecting portion 22 is integrally formed at the base end, and a pair of side wall plates 24 erected from both side edges of the bottom plate 23 and facing the width direction of the terminal body 11. 25 and an upper plate 26 connecting the upper edge portions of the pair of

side wall plates

24, 25 are formed in a rectangular tube structure.

The bottom plate 23 is equipped with a bottom side clamping plate 27 that extends from the front end and is folded back to the upper side of the bottom plate 23. Further, the upper plate 26 is provided with an upper clamping plate 28 extending from the front end thereof and folded back to the lower side of the upper plate 26.

The bottom side clamping plate 27 and the upper side clamping plate 28 are arranged to face each other in the vertical direction within the rectangular tube structure. The bottom-side sandwiching plate 27 and the upper-side sandwiching plate 28 make a pair with each other, sandwich the terminal body 11 inserted between the pair of sandwiching plates, and establish a conductive connection with the plate-like terminal 10.

sandwich plates

27 and 28. The pair of

side wall plates

24, 25 regulate the movement of the terminal body 11 in the width direction when the spring portions 12 on both sides of the terminal body 11 inserted between the pair of sandwiching

plates

27, 28 come into contact with each other.

As shown in FIG. 1, the electric wire connecting portion 22 in the female terminal fitting 20 has caulking pieces 22 b extending on both sides of a bottom wall 22 a that is connected to the base end of the bottom plate 23. The electric wire connecting portion 22 is electrically connected to the electric wire conductor by caulking the caulking piece 22b on the electric wire conductor placed on the bottom wall 22a.

The plate-like terminal 10 described above is configured such that the terminal body 11 is inserted between the pair of sandwiching

plates

In the plate-like terminal 10 of the present embodiment, the spring portion 12 protruding on the both side surfaces 11a of the terminal body 11 during the fitting operation to the terminal fitting portion 21 is a pair of side wall plates 24 in the terminal fitting portion 21. 25, the movement of the terminal body 11 in the width direction is restricted. Therefore, rattling in the width direction of the plate-like terminal 10 can be prevented during the fitting operation to the terminal fitting portion 21.

Further, in the plate-like terminal 10 of the present embodiment, the spring portion 12 on the terminal body 11 that contacts the pair of

side wall plates

24 and 25 in the terminal fitting portion 21 is positioned in the fitting direction to the terminal fitting portion 21. The two spring portions 12 are simultaneously in contact with one

side wall plate

24, 25, so that the contact between one spring portion 12 and the

side wall plates

24, 25 is rotated. The terminal body 11 can be prevented from swinging in the width direction as a fulcrum.

That is, in the plate-like terminal 10 according to the present embodiment, not only the terminal body 11 is prevented from rattling in the width direction but also in the width direction of the terminal body 11 during the fitting operation to the mating terminal fitting portion 21. Can be prevented, and an accurate fitting connection can be facilitated.

Further, in the plate-like terminal 10 of the present embodiment, the spring portions 12 on the side surfaces 11a are arranged symmetrically with respect to the central axis O1 of the terminal body 11. Therefore, the reaction force received by each spring portion 12 from the

side wall plates

24, 25 of the terminal fitting portion 21 is canceled by the spring portions 12 arranged at positions symmetrical to the central axis O <b> 1 of the terminal body 11. Therefore, the reaction force received by each spring portion 12 can prevent the terminal body 11 in the middle of fitting from being inclined in the width direction. Therefore, it becomes easy to insert the said plate-shaped terminal 10 in the terminal fitting part 21 straight along a fitting direction.

Further, in the plate-like terminal 10 of the present embodiment, a line connecting the tips of the spring portions 12 arranged on the same side surface 11 a of the terminal body 11 is a straight line parallel to the fitting direction of the plate-like terminal 10. Therefore, the two spring portions 12 that come into contact with the

side wall plates

24 and 25 of the terminal fitting portion 21 function as a slide guide when the plate-like terminal 10 is inserted straight along the fitting direction. Occurrence of oblique insertion that is inserted while the terminal 10 is inclined in the width direction can be prevented, and the operability when the plate-like terminal 10 is fitted can be further improved.

In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

For example, the number of spring portions protruding from both side surfaces of the terminal body can be set to an appropriate value of 3 or more.

Further, the specific structure of the spring portion protruding from both side surfaces of the terminal body is not limited to the above-described embodiment. For example, instead of an arch shape in which both ends are coupled to the terminal body, a cantilever structure in which one end is separated from the terminal body may be employed.

In addition, the plurality of spring portions arranged on the same side surface of the terminal body have side surfaces 11a of the terminal body 11 such that lines connecting the tips of the plurality of spring portions are straight lines n1 and n2 shown in FIG. You may make it set the protrusion length from. The straight lines n1 and n2 in FIG. 2 have an inclination angle at which the distance from the central axis O1 of the terminal body 11 increases toward the base end side of the terminal body 11.

In this way, the amount of deformation of the spring portion 12 located on the proximal end side of the terminal body 11 is greater when it contacts the side wall plate of the terminal fitting portion than the spring portion 12 located on the distal end side. Therefore, an operation feeling in which the contact resistance gradually increases as the fitting of the terminal body 11 to the terminal fitting portion 21 proceeds can be provided.
