Abstract

A coaxial connector has a structure in which slits into which the both sides of a core wire crimp part are to be inserted are respectively formed on facing inner walls of a core wire containing groove in an inner housing and the core wire crimp part is covered with the inner housing and a terminal fitting by crimping of the terminal fitting.

Claims

1. A coaxial connector to which a terminal of a coaxial wire which includes a core wire, a braided wire covering an outer periphery of the core wire via an insulating inner cover and an insulating outer cover covering an outer periphery of the braided wire is to be connected, comprising:

an inner terminal to be connected to a terminal of the core wire and to be connected to a mating terminal;

an inner housing in which the inner terminal is to be contained together with the terminal of the core wire; and

a terminal fitting formed by a crimp part to which the braided wire and the insulating outer cover of the coaxial wire are to be crimped and a body part to which the inner housing is to be fixed in a state of containing the inner terminal, wherein

in the inner housing, in a housing body which is formed by a terminal connection side containing part into which a mating terminal connection part of the inner terminal is to be inserted and a core wire crimp part containing part in which a core wire crimp part to which the inner terminal and the terminal of the core wire are crimped is to be contained and which is to be fixed to the terminal fitting by crimping of the terminal fitting, a core wire containing groove which is disposed to be contiguous with the terminal connection side containing part and the core wire crimp part containing part and in which the core wire crimp part and the inner terminal are to be contained is formed,

slits into which the both sides of the core wire crimp part are to be inserted are respectively formed in facing inner walls of the core wire containing groove, and

the core wire crimp part is to be covered with the inner housing and the terminal fitting by crimping of the terminal fitting.

2. The coaxial connector according to claim 1, wherein

the body part of the terminal fitting is formed by a crimp part for inner housing which is to be crimped to the inner housing and an inner housing containing cylinder part for containing the inner housing,

the crimp part of the terminal fitting is formed by an insulating outer cover crimp part to which the insulating outer cover is to be crimped and a braided wire crimp part to which the braided wire is to be crimped, and

the crimp part for inner housing is disposed on the side opposite to the insulating outer cover crimp part with the braided wire crimp part sandwiched therebetween.
