Abstract
An electrical connector includes contacts to be connected to lead wires and a housing having apertures for receiving the contacts. The lead wires are connected to the contacts when the contacts are forced into the apertures of the housing. Each of the contacts comprises at one end a contact element to be in contact with an external terminal and at the other end a connection portion formed with a lead aperture through which a lead wire passes and with a slit continuous with the lead aperture. Edges of the slit pierce into an insulating coating of the lead wire and connect with a core of the lead wire under pressure. The housing is formed with through-apertures through each of which the contact element of each of the contacts extends and with receiving apertures each for receiving the lead wire under a condition that the edges of the slit of the connection portion of the contact pierce into the insulating coating of the lead wire and connect with the core of the lead wire under pressure and a remaining insulating coating is doubled. A doubled end of the lead wire received in each of the receiving apertures is positioned by a shoulder formed by a boundary wall between the receiving aperture and the through-aperture.
