Abstract

A braided part connection structure includes a conductive braid and a conductive member electrically connected and fixed to the braid and made of a conductive plate material. The conductive member includes a braid joining portion. The braid joining portion includes, at a part of the conductive member in a longitudinal direction of the conductive member, a plurality of openings formed at intervals with each other along a direction intersecting the longitudinal direction and a welded portion defined by two adjacent openings of the plurality of openings. The braid joining portion is provided on the braid in an overlapping manner and the welded portion is laser-welded onto the braid.

First claim

What is claimed is:

1. A braided part connection structure for a shielded cable, the shielded cable including an electric wire and an outer cover, the braided part connection structure comprising:
a conductive braid including a covered portion between the electric wire and the outer cover and an exposed portion exposed outside of the outer cover; and
a conductive member electrically connected and fixed to the braid and made of a conductive plate material,
wherein the conductive member includes a braid joining portion, a braid connection end, and a fitting end, the conductive member terminates at each of the braid connection end and the fitting end, and the fitting end is spaced away from the braid in a longitudinal direction of the shielded cable,
wherein, the braid joining portion is disposed on the braid connection end,
wherein the braid joining portion includes, at a part of the conductive member in the longitudinal direction, a plurality of openings formed at intervals with each other along a direction intersecting the longitudinal direction and a welded portion defined by two adjacent openings of the plurality of openings,
wherein the braid joining portion is provided on the exposed portion of the braid in an overlapping manner and a laser weld bead connects the welded portion onto the exposed portion of the braid, and
wherein the braid joining portion is spaced away from the outer cover.

2. The braided part connection structure according to claim 1 ,
wherein the plurality of openings are a plurality of notched holes formed at the braid connection end of the conductive member, and
wherein the welded portion is a protruding piece defined by two adjacent notched holes of the plurality of notched holes.

3. The braided part connection structure according to claim 1 ,
wherein the plurality of openings are a plurality of through holes formed in the vicinity of the braid connection end of the conductive member, and
wherein the welded portion is a bridge piece defined by two adjacent through holes of the plurality of through holes.

4. The braided connection structure according to claim 1 ,
wherein the conductive member is a shield member formed by bending the conductive plate material into a cylindrical shape,
wherein the braid is a cylindrical shield braid covers the electric wire along a longitudinal direction of the electric wire, and
wherein the braid joining portion covers an end of the shield braid and the laser weld bead connects the welded portion onto an outer periphery of the shield braid.

5. A braided part connection structure comprising:
a conductive braid; and
a conductive member electrically connected and fixed to the braid and made of a conductive plate material,
wherein the conductive member includes a braid joining portion,
wherein the braid joining portion includes, at a part of the conductive member in a longitudinal direction of the conductive member, a plurality of openings formed at intervals with each other along a direction intersecting the longitudinal direction and a welded portion defined by two adjacent openings of the plurality of openings,
wherein the braid joining portion is provided on the braid in an overlapping manner and a laser weld connects the welded portion onto the braid,
wherein the conductive member includes a connection terminal configured to be fitted and electrically connected to a counterpart terminal, the connection terminal is a hollow cylinder,
wherein the braid is a flexible conductor to which the braid joining portion of the conductive member is connected and includes a flat end,
wherein the braid joining portion is a flat plate and extends from the connection terminal at a right angle,
wherein the braid joining portion is provided on the flat end of the flexible conductor in an overlapping manner and the laser weld connects the welded portion onto the flat end of the flexible conductor, and
wherein the hollow cylinder includes an opened end, the conductive member includes an intermediate plate that extends from and is connected to the opened end, and the braid joining portion is connected to the intermediate plate and extends from the intermediate plate at the right angle.
