Abstract

A terminal-equipped wire ( 1 ) includes a connector terminal ( 2 ), a wire ( 3 ), a relay conductor ( 4 ) and a sealing member ( 5 ). The connector terminal ( 2 ) is arranged in an insertion hole ( 71 ) provided in a connector case ( 7 ). The wire ( 3 ) is formed by bundling a plurality of conductors ( 31 ). The relay conductor ( 4 ) is composed of one conductor and electrically connects the connector terminal ( 2 ) and the wire ( 3 ). The sealing member ( 5 ) is mounted on the outer periphery of the relay conductor ( 4 ) and arranged in the insertion hole ( 71 ) to close a clearance (S 1 ) between the inner periphery of the sealing member ( 5 ) and the outer periphery of the relay conductor ( 4 ) and a clearance (S 2 ) between the outer periphery of the sealing member ( 5 ) and the inner periphery of the insertion hole ( 71 ).

First claim

The invention claimed is:

1. A terminal-equipped wire, comprising:
a connector terminal to be arranged in an insertion hole provided in a connector case;
a wire formed by bundling a plurality of conductors;
a conductive relay conductor having a first shaft to be connected to a terminal connecting portion, a second shaft extending opposite the first shaft, and a diameter enlarged portion having a larger diameter than the first and second shafts;
a connection terminal having a first connecting portion connected to the second shaft of the relay conductor and a second connecting portion connected to the wire; and
a sealing member in the form of an O-ring mounted on an outer periphery of the diameter enlarged portion, the sealing member being arranged in the insertion hole to close a clearance between the sealing member and the relay conductor and a clearance between the sealing member and the insertion hole.

2. The terminal equipped wire of claim 1 , wherein the sealing member includes:
a connecting outer peripheral portion to be connected to at least one of a terminal connecting portion provided in the connector terminal and a connecting portion provided in the connection terminal; and
a sealing portion for closing the insertion hole.

3. The terminal-equipped wire of claim 2 , wherein the connecting outer peripheral portion is composed of a first connecting outer peripheral portion to be connected to the terminal connecting portion and a second connecting outer peripheral portion to be connected to the connecting portion.

4. The terminal equipped wire of claim 3 , wherein the connection terminal is formed with a projection for coming into contact with the insertion hole.
