Abstract:
1. A board-to-board coaxial connector which is configured by one coaxial connector pair comprising: a coaxial connector receptacle which is to be surface mounted to one printed circuit board; and a coaxial connector plug which is to be surface mounted to another printed circuit board, said coaxial connector receptacle and said coaxial connector plug being fittable with each other, wherein: a contact portion is formed in an internal conductor housing portion of an insulative plug body into which a pin-like receptacle center conductor is to be inserted, said contact portion has: a stationary contact piece portion which is perpendicularly bent from a solder connecting portion of a plug internal conductor to extend in an axial direction of said connector; movable contact piece portions which are continuous to said stationary contact piece portion, which are juxtaposed in a circumferential direction of said connector, and which extend in the axial direction of said connector, and, when said receptacle center conductor is inserted into said internal conductor housing portion, said movable contact piece portions are elastically displaced in a direction perpendicular to the axial direction of said connector to be elastically contacted with an outer circumferential face of said receptacle center conductor, together with said stationary contact piece portion; a cylindrical contact portion of a plug external conductor which is to be in contact with a receptacle outer circumference conductor is provided with a plurality of slits to be split into plural contact piece portions which are elastically displaceable in a radial direction of said connector; and said contact portion with respect to the receptacle outer circumference conductor is formed on an inner face of a tip end side of each of said contact piece portions, said contact portion protruding inwardly.
