Here, it is preferable that the contact of the concave portion is provided on the male terminal insertion direction side with respect to itself in the concave portion, and the contact of the convex portion is provided on the terminal insertion direction side in the convex portion.

Further, it is preferable that the inner peripheral surface in the female terminal portion and the terminal insertion direction side of the concave portion are formed as tail tapered portions whose distance from the axis line in an orthogonal direction orthogonal to the axis line direction gradually becomes shorter as going toward the terminal insertion direction, the outer peripheral surface in the male terminal portion and a front end portion on the terminal insertion direction side of the convex portion and a portion inserted into the tail tapered portion of the female terminal portion are formed as tapered portions whose distance from the axis line in an orthogonal direction orthogonal to the axis line direction gradually becomes shorter as going toward the terminal insertion direction, the contact of the concave portion is provided at the tail tapered portion, and the contact of the convex portion is provided at the tapered portion.

Further, it is preferable that the concave portion has a wedge groove shaped portion in which a radial outer side of 2 or 2 of the concave wall surfaces in a circumferential direction bounded by a radial direction is narrowed as it goes to a radial outer side, the convex portion has a wedge-shaped portion in which a radial outer side of 2 or 2 of the convex wall surfaces in a circumferential direction bounded by a radial direction is narrowed as it goes to a radial outer side, the contact of the concave portion is provided on each of the concave wall surfaces in the wedge groove shaped portion, and the contact of the convex portion is provided on each of the convex wall surfaces in the wedge-shaped portion.

In order to achieve the above object, a fitting connector according to the present invention includes: a female connector provided with a female terminal and a female housing accommodating the female terminal; and a male connector provided with a male terminal and a male housing accommodating the male terminal, the female terminal and the male terminal respectively having a common axis in a terminal inserting and extracting direction, the female terminal having a female terminal portion of a concave shape, the male terminal having a male terminal portion of a convex shape, the male terminal portion being insertable and extractable in the female terminal portion in the terminal inserting and extracting direction, the female terminal portion having an inner peripheral surface in a direction surrounding the axis and having a plurality of concave portions which are recessed more radially outward than the inner peripheral surface and extend in an axis direction of the axis and are arranged radially centering on the axis at intervals from each other in a circumferential direction of the inner peripheral surface, the male terminal portion having an outer peripheral surface in the direction surrounding the axis and having a maximum number of convex portions which is the same as the concave portions, the convex portions are capable of being inserted into and pulled out of the concave portions in the terminal insertion and pulling direction, protrude radially outward from the outer peripheral surface, extend in the axial direction of the axis, and are arranged radially around the axis at intervals in the circumferential direction of the outer peripheral surface, and the pair of concave portions and the pair of convex portions each have a contact point that is pressed against each other in the axial direction at an insertion completion position of the male terminal portion with respect to the female terminal portion so as to come into contact with each other.

Effects of the invention

The male and female terminals and the mating connector according to the present invention are provided with contacts at the concave portion and the convex portion, and when the male terminal portion is inserted into an insertion completion position with respect to the female terminal portion, the female terminal portion and the male terminal portion are pressed against each other in the axial direction at the insertion completion position, and the contacts are brought into contact with each other. Therefore, the male and female terminals and the mating connector are less susceptible to external input such as vibration than when the male and female terminals are energized via so-called spring contacts, and the contact pressure between the contacts of the concave portion and the contacts of the convex portion is less likely to change. Therefore, the male and female terminals and the fitting connector can maintain the contact pressure at a desired level, and thus can reduce the contact resistance between the contact points of the concave portions and the contact points of the convex portions.
