1. A connector assembly comprising:
a connector fitted to a counter connector along a fitting direction;
a housing of an electronic device, the housing accommodating the connector and having an insertion port into which the counter connector is inserted; and
a waterproof cap detachably attached from an outside of the housing to the housing and used to close the insertion port,
the waterproof cap including:
a cap body extending in the fitting direction,
a first protruding portion disposed on an outer peripheral surface of the cap body, continuously surrounding an entire periphery of the outer peripheral surface while protruding from the outer peripheral surface in a plane orthogonal to the fitting direction, and made of an elastic material; and
a second protruding portion disposed on the outer peripheral surface on a front end side of the cap body in the fitting direction from a position at which the first protruding portion is disposed, protruding from the outer peripheral surface in a direction orthogonal to the fitting direction, and made of an elastic material,
wherein when the waterproof cap is attached to the housing, the first protruding portion is press-fitted to the insertion port of the housing and contacts an entire periphery of an inner peripheral surface of the insertion port while being elastically compressed, and the second protruding portion is inserted into the connector and contacts at least two inner surfaces of the connector facing each other while being elastically compressed.
