Abstract

A shield conductive path includes a shielded wire (10). An outer conductor shell (20) has a tubular shell body (21), a shell-side fixing portion (26) and a coupling (23) extending therebetween. The shell-side fixing portion (26) is fixed to a front part (13F) of a braided wire (13). An inner conductor terminal (40) has a terminal body (41) at a front part and a terminal-side fixing portion (42) in a rear part. The terminal body (41) is accommodated in the shell body (21). The terminal-side fixing portion (42) is fixed to a front part (11F) of a core (11) in the coupling (23), and a shield cover (50) surrounds an inner conductor connecting portion (45) composed of the front part (11F) of the core (11) and the terminal-side fixing portion (42) in a non-contact manner.

First claim

What is claimed is:

1. A shield conductive path, comprising:
a shielded wire having a core surrounded by a tubular shield layer;
an inner conductor terminal having a terminal-side fixing portion electrically conductively fixed to a front part of the core to define an inner conductor connecting portion and having a terminal body forward of the inner conductor connecting portion;
a shell-side dielectric surrounding the terminal body;
a cover-side dielectric surrounding the inner conductor connecting portion;
an outer conductor shell including a tubular shell body formed at a front end part and surrounding the shell side dielectric, a shell-side fixing portion in a rear end part and being electrically conductively fixed to a front end part of the shield layer of the shielded wire, and a coupling that electrically conductively couples the shell body and the shell-side fixing portion; and
a shield cover including a cover-side fixing portion electrically conductively fixed in surrounding relationship to at least one of the outer conductor shell and the shield layer and a cover body engaged with the cover-side dielectric and surrounding the inner conductor connecting portion in a non-contact manner.

2. The shield conductive path of claim 1 , wherein the cover body includes a flexible cover displaceable in a radial direction.

3. The shield conductive path of claim 2 , wherein:
the cover-side dielectric includes a flexible covering configured to displace in the radial direction integrally with the flexible cover.

4. The shield conductive path of claim 1 , wherein the cover body and the coupling are formed with displacement restricting portions configured to restrict a relative displacement of the cover body with respect to the coupling by being locked to each other.

5. The shield conductive path of claim 1 , wherein the coupling is composed of two side walls disposed to sandwich the inner conductive connecting portion in a width direction intersecting an axis.
