  • the insulating housing defines a plurality of terminal receiving chambers and has a plurality of terminal holding portions for locking the electric wire side terminals inserted into the terminal receiving chambers, and the terminal holding housing.
  • a short-circuit member holding housing portion that holds the short-circuit member at a position where the short-circuit member is separated from the terminal holding housing portion.
  • the terminal holding housing portion and the short-circuit member holding housing portion Are coupled to each other so as to allow a relative displacement of the short-circuit member holding housing part with respect to the terminal holding housing part within a limited range.
  • the short-circuit member holding housing portion that holds the short-circuit member can be relatively displaced in a limited range with respect to the terminal holding housing portion that receives and locks the electric wire side terminal. Since both housing parts are joined together, unlike the conventional joint connector in which the entire insulating housing is integrally formed, the terminal holding is performed while the holding power of the shorting member by the shorting member holding housing is increased.
  • the short-circuit member fitted to the wire-side terminal following the minute displacement of the wire-side terminal in the housing portion can be displaced within a limited range together with the short-circuit member holding housing portion. This suppresses the relative displacement between the electric wire side terminal and the short-circuit member, and makes it possible to suppress the wear of the contact portion between the two due to the relative displacement.
  • each terminal locking portion of the terminal holding housing portion is a lance that can be elastically bent and deformed in a direction orthogonal to the axial direction of the electric wire side terminal, the relative of the electric wire side terminal to the terminal holding housing portion Therefore, it is very effective that the short-circuit member holding housing portion can be displaced relative to the terminal holding housing portion.
  • the short-circuit member holding housing portion has a contact portion that defines a tip position of the wire-side terminal by contacting the wire-side terminal fitted to the terminal fitting portion of the short-circuit member. It is preferable. Accordingly, excessive insertion of the electric wire side terminal into the terminal accommodating chamber can be prevented with a rational structure using the short-circuit member holding housing portion.
  • the short-circuit member holding housing portion has a terminal insertion portion that receives the insertion of the tip end portion of the electric wire side terminal fitted to the terminal fitting portion of the short-circuit member.
  • the insertion of the distal end portion of the electric wire side terminal into the terminal insertion portion facilitates the displacement of the short-circuit member holding housing portion following the displacement of the electric wire side terminal.
  • the terminal insertion portion is a concave portion having a bottom portion, and the bottom portion abuts on a tip end of the electric wire side terminal inserted into the terminal insertion portion, thereby defining a tip position of the electric wire side terminal. It is more preferable to configure the contact portion. Thereby, both the function which accelerates
  • the short-circuit member holding housing portion is open to the terminal accommodating chamber side and receives the insertion of the short-circuit member in the same direction as the insertion direction of the electric wire-side terminal, and holds the short-circuit member insertion portion, It is preferable to include a short-circuit member restraining portion that restrains the short-circuit member by striking the short-circuit member inserted into the short-circuit member insertion portion in a direction opposite to the insertion direction of the short-circuit member.
  • This structure makes it possible to set the short-circuit member in the short-circuit member holding housing portion with a simple operation of inserting the short-circuit member into the short-circuit member insertion portion, and the short-circuit member holding housing portion It is possible to reliably hold the wire side terminal against the insertion force.
  • each terminal locking portion of the terminal holding housing portion is a lance that can be elastically bent and deformed in a direction perpendicular to the axial direction of the electric wire side terminal
  • the terminal holding housing portion can be bent and deformed.
  • the short-circuit member holding housing portion is molded from a second material having a second elastic modulus larger than the first elastic modulus. preferable. This means that the terminal holding housing portion and the short-circuit member holding housing portion are configured as separate members, so that the lance constituting the terminal locking portion in the terminal holding housing portion is guaranteed to be deformed and the short-circuit is performed. It is possible to achieve both a sufficient holding force of the short-circuit member by the member holding housing part.
  • one of the terminal holding housing part and the short-circuit member holding housing part is limited to the other housing part.
  • maintaining the said other housing part so that the relative displacement in the defined range may be permitted is suitable.
  • the short-circuit member protrudes from the base portion to the opposite side of the terminal fitting portion, and includes a plurality of connector terminal portions that can be fitted to each of the plurality of connector terminals included in the counterpart connector. You may have.
  • the housing portion with a case further includes a hood portion that extends from the casing portion and covers the plurality of connector terminal portions from the outside.
