Abstract: A sequential connection-type connector including an insulative housing having contact-accommodating cavities, receptacle contacts accommodated in the cavities and an additional contact arranged between one of the receptacle contacts and an inside wall of the housing. The additional contact includes a contact plate portion contacting the receptacle contact, an engaging portion projecting into the inside wall of the housing, a bent portion extending from a rear end of the contact plate portion and interposed between the contact plate portion and the engaging portion, and a contact arm extending from a front end of the contact plate portion and projecting forward beyond a front end of the receptacle contact across the opening defined in the receptacle contact for insertion of a mating male contact.

Abstract: An electrical connector comprises a terminal block and a housing. The terminal block has an electric wire receiving passageway that communicates with a spring receiving passageway. The terminal block moves between a pre-latched position and a locked position. The housing is provided with a contact having a piercing member for piercing a sheathing member of an electric wire. The piercing member urges the electric wire toward the spring receiving passageway when the terminal block is moved to the locked position. A spring member is arranged in the spring receiving passageway. The spring member has a contact retaining portion for urging the electric wire toward the piercing member as the piercing member urges the electric wire toward the contact retaining portion. A support arm additionally presses the electric wire toward the piercing member.
