the second cover body is coupled to the first cover body to be elastically moved with respect to the first cover body according to a position of the insertion protrusion in the through hole, and

a movement groove in which the second cover body is elastically moved is formed in the receptacle body.

11. An optical connector comprising:

a receptacle assembly to be coupled to a substrate;

a cover coupled to the receptacle assembly;

a photoelectric element array coupled to the receptacle assembly; and

a plug assembly inserted into a reception groove formed in the receptacle assembly and movably coupled to the receptacle assembly, wherein:

the plug assembly includes a plug body inserted into the reception groove to be movable between a first position spaced apart from the photoelectric element array and a second position connected to the photoelectric element array, and a hook member formed to protrude from the plug body,

the cover includes a support member which presses the plug assembly in a first direction from the first position toward the second position and supports the plug assembly connected to the photoelectric element array,

the receptacle assembly includes a receptacle body in which the reception groove is formed, a protruding member formed on the receptacle body to protrude toward the reception groove, and a hook groove formed in the protruding member,

the hook member is inserted into the hook groove as the plug assembly is moved to the second position, and

the protruding member supports the hook member inserted into the hook groove,

the cover includes a cover body coupled to the receptacle assembly to be movable in the first direction and a second direction opposite the first direction, and a fixing member configured to fix the cover body, and
