  The above cited reference 1 does not describe how to prevent terminal disconnection (terminal double disconnection prevention).

  Therefore, it is necessary to prepare a connector for pulling out the wire as it is without restricting the wire drawing direction, and a connector for restricting the wire drawing direction to a certain direction, which increases the number of parts and increases the cost. .

  The present invention has been made to solve the above-described disadvantages. By sharing one rear holder, the number of parts is not increased, the cost is reduced, and the wire drawing direction is not restricted and the drawing direction is not restricted. In addition, a connector and an electric wire restriction cover that can restrict the direction in which the electric wire is drawn out in a certain direction are provided.

  The connector according to the present invention provides a connector housing having one of the two rear holders provided with a terminal disconnection preventing portion, which is rotatable at a terminal disconnection prevention position and a non-terminal disconnection prevention position via a hinge. The other rear holder divided into two with a terminal disconnection prevention portion attached to the connector housing so as to face the one rear holder rotated to the terminal disconnection prevention position, and the pivoted to the terminal disconnection prevention position The rear holder portion corresponding to the other rear holder is positioned so as to face one rear holder, and is attached to the connector housing. The electric wire regulating cover is divided into two facing the one rear holder rotated to the terminal disconnection preventing position. One wire restriction cover portion and the other wire restriction cover portion divided into two parts connected to the one wire restriction cover portion via a hinge, wherein the one wire restriction cover portion is the terminal. It has the said rear holder part attached so that the said one rear holder rotated to the removal prevention position may be opposed.

  The wire regulating cover according to the present invention is provided for a connector housing having one of the two rear holders provided with a terminal detachment preventing portion, which is rotatable between a terminal detachment prevention position and a non-terminal detachment prevention position via a hinge. An electric wire restricting cover for restricting a pulling direction of the electric wire attached, to the other rear holder divided into two to be attached to the connector housing so as to face the one rear holder rotated to the terminal disconnection preventing position. It has a corresponding rear holder part, and is composed of one divided electric wire restriction cover part and the other divided electric wire restriction cover part connected to the one electric wire restriction cover part via a hinge, The rear holder part has a terminal drop prevention part.

  According to the connector of the present invention, the connector housing having one rear holder is configured so that the other rear holder and the wire restriction cover can be selected and attached, so the number of parts can be reduced by sharing one rear holder. Without increasing the cost, it is possible to pull out the wire as it is without restricting the drawing direction of the electric wire or to restrict the drawing direction of the electric wire to a certain direction while reducing the cost.
