Abstract: A terminal includes a tube part to which a mating terminal is inserted, a spring piece disposed in the tube part and elastically contacts the mating terminal, and a mating terminal guide part formed by forming notches on both sides of an extended portion extended from a front end of a bottom wall, and bending a portion between the notches toward the top wall side. A front end of a first corner portion where the top wall and a side wall intersect, a front end of a second corner portion where the side wall and the bottom wall intersect, a front end of a third corner portion where the bottom wall and a side wall intersect, a front end of a fourth corner portion where the side wall and the top wall intersect, and a front end of the mating terminal guide part are positioned on a same plane.

Abstract: In a connection terminal including a box-shaped connection portion having an insertion opening into which a mating connection portion is inserted, and an elastic piece that is elastically deformable, is arranged inside the connection portion, with an free end arranged on a side of the insertion opening, and has a contact portion that comes into contact with the mating connection portion, the connection portion is provided with a protective wall protruding toward an inside of the connection portion and arranged adjacent to the free end of the elastic piece, and a side of the free end of the elastic piece is arranged so as to intersect an extension line connecting a protruding end of the protective wall and an opening edge of the insertion opening facing the protruding end.

Abstract: A locking member is inserted into a cavity portion in a housing, and the side walls of the locking member are used to constitute part of the outer wall of the terminal accommodating chamber. On the inner surfaces of first locking projections respectively provided on the one-end-face sides of the present two side walls, there are projectingly provided guide ribs so as to extend in parallel to the insertion direction of a connecting terminal. When inserting the connecting terminal into the terminal accommodating chamber, even in case where the connecting terminal is inserted in an inclined manner, the connecting terminal is guided by the guide ribs and the inclination thereof is corrected by the guide ribs, whereby the connecting terminal can be inserted smoothly and the leading end of the connecting terminal is prevented from interfering with the terminal accommodating chamber, the locking member, first locking projections.
