  • Patent number: 11146023
    Abstract: A connector connection structure includes a first connector and a second connector. A second component of the first connector includes a pair of locking arm portions protruding outwardly from an outer periphery of a main body portion of the second component at opposite end portions of the outer periphery. A first component of the first connector includes an abutting surface extending in an up-and-down direction on an inner periphery of a cylindrical portion of the first component and facing toward a rear side of the first connector in a fitting direction. The pair of locking arm portions and the abutting surface have a structure in which at least one part of a tip surface of the locking arm portions first receives a force from the abutting surface when the tip surface receives the force on the rear side in the fitting direction from the abutting surface.
