Therefore, a single insulating member 30 can be used as a member that prevents contact between the portions of each exposed conductor 23 that are arranged in a row in the vertical and left-right directions. Moreover, since the insulating member 30 is arranged in a shape extending in the left-right direction as a whole between the portions of each exposed conductor that are adjacent in the vertical direction, the overall shape of the insulating member 30 can be simplified and made compact.
  • the first member 61, the second member 62, and the third member 63 are assembled in sequence from below while sandwiching the first wiring member 20A and the second wiring member 20B therebetween, and the receiving member 90, the insulating member 30, and the holding member 80 are also assembled in sequence from below. Therefore, the assembly work of the connector 10 can be efficiently performed using an automated machine or the like. Furthermore, since each hole punching pin 83 penetrates the respective sheet portions 21 of the first wiring member 20A and the second wiring member 20B collectively, the efficiency of the assembly work can be further improved.
  • both the holding member and the receiving member are held (connected) separately from the housing at the rear of the housing.
  • at least one of the holding member and the receiving member may be held integrally with the housing at the rear of the housing.
  • the sheet portion of the wiring member is configured to be punched by the hole punching pin while being sandwiched between the hole punching pin of the holding member and the pin receiving portion of the receiving member.
  • the connector may not include a receiving member, and the sheet portion of the wiring member may be configured to be punched only by the hole punching pin of the holding member.
  • the wiring member is composed of the first wiring member and the second wiring member.
  • the wiring member may be composed of only one of the first wiring member and the second wiring member, or may further include another wiring member in addition to the first wiring member and the second wiring member.
  • an insulating member is disposed between each pair of adjacent wiring members.
  • the terminal fitting is configured to be connected to the electric wire by sliding the slide member to the connecting position relative to the connecting member.
