<P>PROBLEM TO BE SOLVED: To provide a coaxial cable waterproof connection structure that can use a general coaxial connector and suitably prevents liquid from entering a connection part through a periphery of a coaxial cable, and a connection body used for the same. <P>SOLUTION: An ultrasonic flowmeter connection structure 20 is a structure having a connection body 30 connected to a connected part 21A of an ultrasonic flowmeter 21, the connection body 30 and connected part 21A being configured such that an O ring 34 is pressed against a cylindrical member 35 in a state in which an SMB plug 33 is coupled to an SMB receptacle 13 and a cover screw part 31S of the connection body 30 is threadably engaged with a connected-side screw part 1A so as to press the O ring 34 and a bottom part 31V of a cover member 31 against each other in a fluid-tight state over the entire outer periphery of the O ring 34 and to press the O ring 34 and a cylinder part 31W of the cover member 31 against each other over the entire outer periphery of the O ring 34, and to press the O ring 34 and a coaxial cable 32 against each other in a fluid tight state over the entire inner periphery of the coaxial cable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
