First, a bottomed hole 50a is formed from the other end surface at the other end of the male-core connector member 50 to which the core wire 10a of the one coaxial cable 10 is connected to one end by caulking or the like. The coil spring 52 and the plunger 54 are inserted, and the bottomed hole 50
The opening end of a is made narrow by caulking or the like to prevent the plunger 54 from coming off. A contact pin 54a is formed integrally with the plunger 54 in the axial direction and protrudes outward through the narrow opening. Therefore, a spring connector is formed at the other end of the male core connector member 50. The bottomed hole 50a only needs to be able to lock one end of the coil spring 52, and the bottomed hole 50a and the hole into which the core wire 10a is inserted may pass through. It should be noted that the core connecting member 56 made of a conductive material to which the core wire 30a of the other coaxial cable 30 is connected by caulking or the like is sufficient if the contact pin 54a of the plunger 54 can be elastically contacted to the end surface thereof, as shown in FIGS. The core connecting member 56 may be a cylindrical body, but may be a solid rod. Furthermore, if the core connecting member 56 is a solid rod, the end surface may be a spherical concave surface.
