CONNECTION METHOD BETWEEN BRAIDED SHIELD LAYER OF SHILED WIRE AND DRAIN WIRE, AND CONNECTION STRUCTURE OF THE SAME

摘要

[Technical Problem];To provide a connection method between a braided shield layer of a shield wire and a drain wire, and a connection structure of the same enabling an easy and reliable connection, using no skilled operation such as soldering, and without an increase of non-shield area which is a problem when the braided shield layer is pulled out and a ground terminal is directly crimped onto the braided shield layer.;[Solution to Problem];A connection method between a braided shield layer of a shield wire and a drain wire sequentially including the steps of a shield terminal insertion step; a shield layer folding and overlapping step; a drain wire overlapping step; a shield ring inserting step; and a crimping step.

1. A connection method between a braided shield layer of a shield wire and a drain wire for electrically connecting the drain wire composed of a plurality of conductive element wires with the braided shield layer provided as a most outer layer formed by braiding a plurality of conductive wire bundles each composed of a plurality of conductive element wires thinner than the conductive element wires of the drain wire, said connection method sequentially comprising the steps of:
a shield terminal insertion step for inserting a ring-shaped shield terminal over a vicinity of an end of the shield wire; a shield layer folding and overlapping step for folding an end side nearer than the shield terminal of the braided shield layer of the shield wire and overlapping with an outer peripheral wall of the shield terminal; a drain wire overlapping step for overlapping the drain wire with a part of an outer side wall of the shield terminal where the braided shield layer is overlapped; a shield ring inserting step for inserting the shield ring over the outer side wall where the braided shield layer is overlapped and a portion where the drain wire is overlapped; and a crimping step for pressing a portion of the shield ring corresponding to the portion where the drain wire is overlapped toward an axial direction of the shield ring from an outer periphery of the shield ring, and deforming the pressed portion into a concave shape.
