ABSTRACT:
A butt-type connection terminal unit comprises first and second connection terminals whose front end surfaces are contacted to each other to make an electric connection therebetween and which include safety structure to prevent a person from accidentally touching the terminal front surfaces. The first and second connection terminals are provided, front end surfaces thereof, with respective plate-like insulators (5, 6) and slits (7, 8) at positions out of phase relative to each other, the plate-like insulators adapted for entrance into the corresponding slits when the front end surfaces are contacted to each other. A butt-type connection terminal unit is obtained in which the plate-like insulators serve to prevent a finger from touching the connection terminals, which realizes a stable electric connection and which is suited for downsizing connectors. A coaxial connector is also provided which employs the above connection terminal unit. A hollow cylinder (34) and a rod (36) are also usable as touch prevention structures.
