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.

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.

For this reason, the vertical width of the distal end portion of the press contact blade 5 is about / to の of the base portion, and is substantially wedge-shaped. This is to make it easy to bite into the covering of the covered electric wire.

In the press contact terminal 1 'of this embodiment, the press contact blades 5 projecting inward from the plate surface of the side plate are all inclined in the same direction. ing. In other words, a pair of rear-side press-contact blades of the pair of front-rear press-contact blades 5 correspond to the press-contact blades 5 shown in FIGS.
(C) and 5 (D) are opposite (+ α). Other parts are the same as those in FIG. 1 and FIG.

In this case, when the electric wire W is pushed through the upper opening of the groove 3, the press contact blade 5 of the press contact terminal bites into the covering W1 of the electric wire, and the wire W2 of the electric wire is inserted into the slot 6 between the pair of press contact blades 5.
Penetrates and the tip of the press contact blade 5 comes into contact with the conducting wire W2. Since this contact is made firmly, the insulation displacement terminal 1 and the electric wire W conduct.

In the embodiment of FIGS. 3 and 4,
Since all the press contact blades are inclined in the same direction, they are hardly displaced with respect to the tension in the arrow Y direction in FIG. 6, but have a slightly lower resistance to the tension in the arrow X direction.

る。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.
