Patent ID: 7156675

Claim:
A coaxial connector with a switch wherein said coaxial connectors comprises: a cylindrical insulation body 10 , 10 ′ which integrally has a pedestal portion 11 , 11 ′ on a bottom side, and in which a plug pin insertion hole 14 , 14 ′ is formed in a center area of an upper face, said plug pin insertion hole enabling a plug pin 100 , 100 ′ of a counter connector to be insertable and extractable along a cylinder axis in a center area inside a cylinder; an external-conductor shell 30 , 30 ′ having a cylindrical shell body 31 , 31 ′ which is fitted to an outside of the cylinder of said insulation body 10 , 10 ′, and a solder connecting portion 32 a , 32 b , 32 ′ which elongates integrally from said shell body 31 , 31 ′ along a bottom face of said insulation body 10 , 10 ′; a stationary connect member 40 , 40 ′ for a switch having a stationary contact portion 41 , 41 ′ which is housed and fixed to a position inside the cylinder of said insulation body 10 , 10 ′ and deviated from a plug pin insertion region 15 , 15 ′, and a solder connecting portion 42 , 42 ′ which elongates integrally from said stationary contact portion 41 , 41 ′ along the bottom face of said insulation body 10 , 10 ′; and a movable connect member 50 , 50 ′ having a plate-spring like movable contact piece portion 51 , 51 ′ configured by a thin metal plate, and a solder connecting portion 55 , 55 ′ which elongates integrally from said movable contact piece portion 51 , 51 ′ along the bottom face of said insulation body 10 , 10 ′, said movable contact piece portion being housed in a cantilevered manner inside the cylinder of said insulation body 10 , 10 ′ and around said plug pin insertion region 15 , 15 ′ so that a plate width direction is in parallel with a direction of insertion and extraction of the plug pin, a free side end portion 54 b , 15 c ′ laterally pass-ing a part of said plug pin insertion region 15 , 15 ′ to elongate to said stationary contact portion 41 , 41 ′, and having a plug pin contact portion 57 , 57 ′ and a movable contact portion 56 , 56 ′ which is elastically contacted with said stationary contact portion 41 , 41 ′ by a spring force, in accordance with fitting with said counter connector, said plug pin 100 , 100 ′ is elastically contacted with said plug pin contact portion 57 , 57 ′, and said movable contact piece portion 51 , 51 ′ is displaced in a direction substantially perpendicular to the direction of insertion and extraction of the plug pin against the spring force, whereby said movable contact portion 56 , 56 ′ is separated from said stationary contact portion 41 , 41 ′, wherein, in said insulation body 10 , 10 ′, plug pin insertion guide walls 17 a , 18 a , 17 a ′ are formed at opposed positions across said plug pin insertion region 15 , 15 ′ inside the cylinder, said plug pin insertion guide walls hanging continuously from a hole wall of said plug pin insertion hole 14 , 14 ′ in the plug pin insertion direction.
