• 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.
