Document Type and Number:
Japanese Patent JP2016133383
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a sufficient waterproof effect without deformation of an elastic seal member at the time of connection of a coaxial cable to a measurement part.SOLUTION: A bottomed cylindrical case 95 is linearly pushed into the front side by screwing an inner screw 96 of a push-in cover 97 into an outer screw 79 of a cylinder part 78 of a body 62. An O-ring 94 and a pressing plate 93 are stored in the bottomed cylindrical case 95, and the tip of the bottomed cylindrical case 95 presses the surface of an elastic seal member 80 annularly. When the upper end part of a coaxial plug 92 is pressed by the bottom of the bottomed cylindrical case 95 via the O-ring 94 and the pressing plate 93, the coaxial plug 92 is fitted into a coaxial reception terminal 81 to establish electrical connection. The O-ring 94 is compressed in the bottomed cylindrical case 95, but the elastic seal member 80 and the O-ring 94 are not twisted, thereby a waterproof structure between a coaxial cable 91 and the body 62 can be achieved.SELECTED DRAWING: Figure 6
