Abstract

A connector for a coaxial cable which enables an end of a shield wire to be held inside a shield terminal as a housing, without generating a backlash, and can be made compact as a whole. Each of crimping barrel parts of a shield terminal is provided with a butting face which is opposed to each of flanges when the crimping barrel parts are folded at its one end, and an inclined face, at the other end at an opposite side to the butting face. The inclined face is brought into sliding contact with the inclined face of the other crimping barrel part when the crimping barrel parts are folded, and the inclined face is inclined to extend in a direction perpendicular to a direction where a pair of the crimping barrel parts are folded.

Claims

1. A connector for a coaxial cable, comprising:

a core wire conduction terminal, connected to a core wire exposed from a terminal end of a shield wire,

an insulating member, which holds the core wire conduction terminal in a state contained therein,

a shield terminal, which is connected to the shield wire by caulking a shield conductor that is positioned around a sheath of the shield wire, and at the same time, holds the insulating member by caulking the insulating member,

wherein the insulating member is provided with two flanges protruding from its outer periphery along a circumferential direction, interposing a determined distance in a longitudinal direction,

the shield terminal is provided with a pair of crimping barrel parts which are erected so as to clamp the outer periphery of the insulating member, for caulking a region of the insulating member interposed between the flanges,

each of the crimping barrel parts is provided with a butting face which is opposed to a corresponding one of the flanges when the crimping barrel part is folded, at its one end, and an inclined face, at the other end at an opposite side to the butting face, the inclined face comes into sliding contact with the inclined face of the other crimping barrel part when the crimping barrel parts are folded, and the inclined face is inclined to extend in a direction perpendicular to a direction where the crimping barrel parts are folded.
