Abstract: In a mold for pressing an electric-wire clamping portion of a terminal, a lower side-wall mold part and an upper side-wall mold part are provided for pressing side walls connected to the electric-wire clamping portion. A pressure face substantially continuously connected to a pressure face of an upper conductor mold part is provided on one end side of the upper side-wall mold part. A taper face is provided on the other end side of the upper side-wall mold part so as to be enlarged toward the other end. Accordingly, side walls pressed between the lower side-wall mold part and the upper side-wall mold part are deformed so that the quantity of deformation at one end is near the quantity of compressive deformation of the electric-wire clamping portion and so that the quantity of deformation is reduced gradually toward the other end side. Thus, local stress concentration is not caused in the side walls so that cracks are prevented from occurring in the side walls.

Abstract: An electrical connector (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.

Abstract: In a mold for pressing an electric-wire clamping portion of a terminal, a lower side-wall mold part and an upper side-wall mold part are provided for pressing side walls connected to the electric-wire clamping portion. A pressure face substantially continuously connected to a pressure face of an upper conductor mold part is provided on one end side of the upper side-wall mold part. A taper face is provided on the other end side of the upper side-wall mold part so as to be enlarged toward the other end.
