B, press-contact blades E projecting from both side plates into the groove portions.
Is known. This press contact terminal is manufactured by bending a single metal plate, and the press contact blade E is protruded into the groove at right angles to the axial direction of the main body (see FIG. 9) by press working. A pair of press-contact blades E sandwiching the slot are pressed against the conductor of the electric wire at opposing end faces P.

[0003] It is said that the length of the straight portion S is required to be 1.5 to 2 times the plate thickness when bending in this type of press working.
The protrusion of the press contact blade E from the side plate becomes small and the straight portion S also becomes short, so that there is a problem that stable press working cannot be performed. In addition, when the size of the terminal is reduced, the thickness of the press contact blade is also reduced, so that the contact area with the electric wire is reduced, and there is a problem that the holding force of the electric wire is insufficient and the connection becomes unstable.

As described above, in the press contact terminal of the present invention, the press contact blade protruding from the groove into which the coated electric wire is inserted is inclined with respect to the axial direction of the electric wire (the plate surface of the side plate of the press contact terminal main body). So that it is perpendicular to the axial direction of the wire,
Even if the width of the press contact terminal body and the slot width are the same, the straight portion can be lengthened. For this reason, even in the case of a small press contact terminal, press molding is easy, it is possible to form a stable shape, and a stable connection to the electric wire can be obtained. In addition, since the press contact terminal is inclined with respect to the axial direction of the electric wire, an effect is obtained in that the displacement is unlikely to occur even if a tensile force is applied to the electric wire according to the inclination direction.
