Abstract

A female connector structure is provided with a shielded cable configured such that an outer periphery of a coated wire including a core and an insulation coating is surrounded by a braided wire, a female terminal including a wire barrel and a connecting tube portion continuous with the wire barrel and to be connected to a mating terminal, an insulating dielectric , a front outer conductor including a front tube portion and a dielectric locking portion to be locked to at least a part of the dielectric, and a rear outer conductor 33 including a rear tube portion for surrounding the outer periphery of the coated wire 13 exposed from the braided wire, a shield crimping portion to be crimped to the braided wire from outside and a front outer conductor crimping portion to be crimped to the dielectric locking portion from outside.

First claim

1 . A connector structure, comprising:
a shielded cable configured such that an outer periphery of a coated wire including a core extending in a front-rear direction and an insulation coating surrounding an outer periphery of the core is surrounded by a shield portion; an inner conductor including a core connecting portion to be connected to the core and a connecting portion continuous with the core connecting portion and to be connected to a mating terminal; an insulating dielectric for surrounding at least an outer periphery of the connecting portion of the inner conductor; a front outer conductor including a front tube portion for surrounding an outer periphery of the dielectric and a dielectric locking portion to be locked to at least a part of the dielectric; and a rear outer conductor including a rear tube portion for surrounding the outer periphery of the coated wire exposed from the shield portion, a shield crimping portion to be crimped to the shield portion from outside and a front outer conductor crimping portion to be crimped to at least a part of the front outer conductor from outside.

2 . The connection structure of claim 1 , wherein:
the dielectric locking portion has a smaller or larger diameter than the front tube portion in a radial direction of the front tube portion, and the dielectric includes a retaining portion configured to come into contact with an inner wall surface of the dielectric locking portion from front or behind.

3 . The connection structure of claim 1 , wherein one of the front and rear outer conductors is provided with a locking projection projecting toward the other and the other is formed with a locking recess to be locked to the locking projection.

4 . The connection structure of claim 1 , wherein:
the front outer conductor crimping portion is formed with a positioning projection projecting inward with the front outer conductor crimping portion crimped to an outer periphery of the front outer conductor, and the positioning projection is passed through the front outer conductor and fit in a positioning recess formed by depressing the dielectric.

5 . The connection structure of claim 1 , wherein one of the front outer conductor crimping portion and a part of the front outer conductor crimped by the front outer conductor crimping portion is provided with a connecting protrusion projecting toward the other with the front outer conductor crimping portion crimped to an outer periphery of the front outer conductor.

6 . A connector structure manufacturing method, comprising:
a step of exposing a core by stripping a front end part of an insulation coating of a shielded cable configured such that an outer periphery of a coated wire including the core extending in a front-rear direction and the insulation coating surrounding an outer periphery of the core is surrounded by a shield portion; a step of arranging an inner conductor in an insulating dielectric with a core connecting portion exposed; a step of accommodating the dielectric inside a front outer conductor; a step of connecting the core connecting portion of the inner conductor to the core exposed from the insulation coating; a step of locking a dielectric locking portion of the front outer conductor to a part of the dielectric; a step of crimping a shield crimping portion provided in a rear outer conductor to the shield portion from outside; and a step of crimping a front outer conductor crimping portion provided in the rear outer conductor to at least a part of the dielectric locking portion from outside.
