A connector includes a connector housing and a fitting assurance member. A repulsion arm of the connector housing is sandwiched between an arm contact portion of a mating connector and an arm displacement regulation portion of the fitting assurance member and the repulsion arm is elastically deformed to be pressed to an outside by a leading end portion of the arm contact portion to be stretched in a straight line, when the leading end portion of the arm contact portion slides on an inner inclined surface of an arm inclined portion of the repulsion arm toward an arm leading end of the repulsion arm.
1. A connector comprising:
a connector housing to be fitted to a mating connector housing by moving in a fitting direction with respect to the mating connector housing; and
a fitting assurance member slidably attached on an outside of the connector housing, and configured to be locked to the mating connector housing by relatively sliding toward the mating connector housing in a connector fitted state in which the connector housing is fitted to the mating connector housing,
wherein the connector housing includes a repulsion arm,
wherein an arm base end portion and an arm inclined portion are integrally formed in the repulsion arm,
wherein the arm base end portion is supported on the connector housing and includes a cantilever structure having a fixing end on a fitting side with the mating connector housing and extending toward an opposite fitting side along the fitting direction,
wherein the arm inclined portion extends from a leading end of the arm base end portion to an arm leading end on the opposite fitting side, and the arm inclined portion is inclined inward the connector housing with respect to the arm base end portion,
wherein the fitting assurance member includes an arm displacement regulation portion facing an outside of the repulsion arm to regulate a displacement of the repulsion arm toward an outside,
wherein the arm inclined portion is arranged so that a leading end portion of an arm contact portion of the mating connector housing comes into contact with an inside of an inner inclined surface of the arm inclined portion and the leading end portion of the arm contact portion of the mating connector housing slides on the inside of the inner inclined surface of the arm inclined portion by a movement of the connector housing in the fitting direction,
wherein the repulsion arm is configured, so that the repulsion arm is sandwiched between the arm contact portion and the arm displacement regulation portion and the repulsion arm is elastically deformed to be pressed to an outside by the leading end portion of the arm contact portion to be stretched in a straight line, when the leading end portion of the arm contact portion slides on the inner inclined surface toward an arm leading end of the repulsion arm, and
wherein the arm inclined portion is arranged so that the leading end portion of the arm contact portion starts sliding on the inner inclined surface of the arm inclined portion before the connector housing and the mating connector housing are fitted to each other, and the leading end portion of the arm contact portion is positioned on the inner inclined surface of the arm inclined portion until the connector housing and the mating connector housing are fitted to each other.
2. The connector according to claim 1 , wherein the connector housing includes an outer housing to be disposed on an outside of the mating connector housing, and
wherein the repulsion arm has a plate shape that is partitioned and defined on a portion of the outer housing by a slit.
