As is apparent from the above description, the following excellent effects can be obtained by the press contact of the electrical connector of the present invention. First, since the blade for cutting the outer skin is provided on the press-fitting end side of the press-contact groove of the contact, when the wire or cable with the outer skin is pressed into this press-contact groove as it is, the outer skin is easily formed by this blade. It can be easily pressed even if the outer skin is thick or the outer skin has a high resin strength. Also,
At this time, the force of press-fitting may be small due to the presence of the blade portion, and there is an advantage that workability can be improved, and at the same time, problems such as poor contact due to incomplete tearing of the outer skin are greatly reduced. Furthermore, the presence of the blade allows the thickness of the metal plate of the contact to remain thick or even thicker, so that a sufficient contact area with the conductor portion of the electric wire / cable can be secured, and a large current capacity (conductivity) can be obtained. There is also the advantage that it can be obtained. Of course, if the tapered outer skin guiding portions are provided on the left and right sides on the opening side of the press contact groove, smooth guiding of the outer skin can be obtained, and better workability can be secured.
