Abstract

A terminal coupled to an electric wire includes a terminal body and a shell. The shell includes a tubular portion and pressing portions 25A and 25B that protrudes from an inner wall of the tubular portion. The tubular portion includes a bottom wall, a first sidewall that projects upward from a first side edge of the bottom wall, a second sidewall that projects upward from a second side edge of the bottom wall, a ceiling that extends from the first sidewall to the second sidewall and is opposite the bottom wall, and a restricting portion that extends from the second sidewall to the first sidewall and overlaps an outer surface of the ceiling.

First claim

The invention claimed is:

1. A terminal coupled to an electric wire comprising:
a terminal body including a holding portion holding the electric wire; and
a shell including:
a tubular portion that covers the holding portion; and
a pressing portion that protrudes from an inner wall of the tubular portion to press the holding portion toward the electric wire, wherein

the tubular portion includes a bottom wall, a first sidewall that projects upward from a first side edge of the bottom wall, a second sidewall that projects upward from a second side edge of the bottom wall, a ceiling that extends from the first sidewall to the second sidewall and is opposite the bottom wall, and a restricting portion that extends from the second sidewall to the first sidewall and overlaps an outer surface of the ceiling.

2. The terminal according to claim 1 , wherein
the restricting portion includes a bending section that extends along the first sidewall and bends toward the bottom wall,
the first sidewall includes a receiving recess that receives the bending section, and
the bending section includes fitting sections that are fitted to a opening edge of the receiving recess.

3. The terminal according to claim 2 , wherein the fitting sections protrude from sides of the bending section in a width direction of the bending section, respectively.

4. The terminal according to claim 1 , wherein
the ceiling includes a fitting tab that protrudes toward the second sidewall, and
the second sidewall includes a fitting hole that receives the fitting tab.

5. The terminal according to claim 1 , wherein the pressing portion protrudes from at least one of the bottom wall and the ceiling.

6. The terminal according to claim 1 , wherein the shell is slidable relative to the terminal body in a direction in which the electric wire extends.

7. A terminal wire assembly comprising:
the terminal according to claim 1 ; and
an electric wire coupled to the terminal.

8. The terminal according to claim 1 , wherein
the holding protrusion includes a pair of a first holding section and a second holding section, each have a protrusion protruding toward an other holding section on opposing surfaces facing each other, and
the first holding section is located at a different position from the second holding section along a tube axis direction of the tubular section.

9. The terminal according to claim 1 , wherein an upper surface of the tubular section has a step between one portion and an other portion along a tube axis direction.
