Abstract

A wire connector is described that suppresses the cutting of wires accidentally. The wire connector 1 includes a wire holder 6 that holds at least two wires, a contact 7 A that electrically connects the two wires and a body 4 that holds the wire holder. The wire holder 6 includes first and second end faces 24 and 26 , and a wire holding portion 25 that includes first and second holding portions 32, 33, 34 and 36 . On the first end face 24 , at portions of circumferential edge portions of the openings 34 c and 36 d of the second holding portions 34 and 36 , protecting portions 23 that project from the first end face 24 and protect the wires are provided.

First claim

What is claimed is:

1. A wire connector comprising: a wire holder holding at least a first wire and a second wire;
a contact electrically connecting the first wire and the second wire; and
a body fixing the contact and holding the wire holder,
wherein the wire holder includes:
a first end face formed on a first end side in a predetermined direction;
a second end face formed on a second end side in the predetermined direction; and
a wire holding portion holding the first wire and the second wire in a state of the first wire and the second wire extending in the predetermined direction and being mutually adjacent in a direction orthogonal to the predetermined direction,
the wire holding portion includes:
a first holding portion holding the first wire; and
a second holding portion formed at a position separated from the first holding portion in a direction orthogonal to the predetermined direction and holding the second wire,
in the first holding portion, an opening enabling the first wire to be pulled through is formed in the first end face and the second end face,
in the second holding portion, an opening enabling the second wire to be pulled through is formed in the first end face and an abutting portion for abutting an end portion of the second wire is formed on the second end face side, and
on the first end face, in at least a portion of a circumferential edge of the opening in the second holding portion, a protecting portion that projects from the first end face and protects the second wire.

2. The wire connector according to claim 1 , wherein the protecting portion has a cylindrical form surrounding the second wire and includes a wire through hole that communicates with the second holding portion and through which the second wire is inserted.

3. The wire connector according to claim 1 , further comprising a second wire holding portion that is not the first wire holding portion, wherein
the second holding portion of the first wire holding portion and the second holding portion of the second wire holding portion are disposed between the first holding portion of the first wire holding portion and the first holding portion of the second wire holding portion.

4. The wire connector according to claim 1 , wherein the body includes a cover that covers the opening of the first holding portion.

5. The wire connector according to claim 2 , further comprising a second wire holding portion that is not the first wire holding portion, wherein
the second holding portion of the first wire holding portion and the second holding portion of the second wire holding portion are disposed between the first holding portion of the first wire holding portion and the first holding portion of the second wire holding portion.

6. The wire connector according to claim 2 , wherein the body includes a cover that covers the opening of the first holding portion.

7. The wire connector according to claim 3 , wherein the body includes a cover that covers the opening of the first holding portion.

8. The wire connector according to claim 5 , wherein the body includes a cover that covers the opening of the first holding portion.
