Patent ID: 7001203

Claim:
A piercing terminal for a coaxial cable including a core conductor wire, an inner insulating layer for covering the core conductor wire, an outer conductor-shielding layer for covering the inner insulating layer, and an outer insulating layer for covering the outer conductor-shielding layer, wherein the piercing terminal is capable of performing a conductive connection with the outer conductor-shielding layer when a piercing blade is embedded in the outer insulating layer to penetrate the outer insulating layer, the piercing terminal comprising: a pair of clipping pieces being arranged to be opposed to each other in a substantially parallel manner; the piercing blade being disposed at a leading end of each of said pair of clipping pieces; and a coupling portion being joined to base portions of said pair of clipping pieces for holding said pair of clipping pieces spaced at a predetermined distance apart; wherein each of said pair of clipping pieces comprises a curved portion which is curved outwardly with respect to the pair of clipping pieces, the curved portion being disposed in a vicinity of the base portion and between the piercing blade and the base portion, wherein the predetermined distance is larger than an outer diameter of the core conductor wire and smaller than an outer diameter of the inner insulating layer, wherein the piercing blade at the leading end of each of said pair of clipping pieces is provided with a sharp edge such that the piercing blade pierces the outer insulating layer, and wherein the respective curved portions of said pair of clipping pieces wrap the inner insulating layer around the outer diameter thereof so as to hold the coaxial cable when said pair of piercing blades pierce the outer insulating layer to penetrate the outer insulating layer and the coaxial cable is pressed down between said pair of clipping pieces with the predetermined distance apart to bring the piercing terminal into a conductive connection with the outer conductor-shielding layer.
