Abstract

A female terminal 12 includes a terminal body 15 and a slider 16. The terminal body 15 includes an upper connecting piece 18A and a lower connecting piece 18B connected to a core wire 13 of an electric wire 11. The slider 16 is movable in a front-rear direction relative to the terminal body 15. The slider 16 includes an upper abutting portion 25A and a lower abutting portion 25B. The upper connecting piece 18A includes an upper protrusion 51A that abuts against the upper abutting portion 25A. The lower connecting piece 18B includes a lower protrusion 51B that abuts against the lower abutting portion 25B.

First claim

What is claimed is:

1. A terminal comprising:
a terminal body including at least one connecting piece extending in an extending direction and being deformable, the at least one connecting piece including:
a contact surface contacting an electric wire; and
a receiving surface on an opposite side from the contact surface; and

a slider movable in the extending direction relative to the terminal body, wherein
the slider has a tube shape,
the slider is fitted on a section of the terminal body including the connecting piece,
the slider includes an abutting portion that abuts against the receiving surface of the at least one connecting piece and presses the at least one connecting piece against the electric wire that is disposed on the contact surface of the at least one connecting piece along the extending direction,
the abutting portion protrudes inward from an inner surface of a wall of the slider,
the abutting portion abuts against the connecting piece when the slider is slid on the terminal body to a contact position,
the at least one connecting piece includes a protrusion protruding from a section of the receiving surface in a direction from the contact surface toward the receiving surface, and
a cross-sectional shape of the receiving surface of the protrusion is different from a cross-sectional shape of a surface of the abutting portion facing the protrusion.

2. The terminal according to claim 1 , wherein the protrusion incudes a convex surface that is curved in a direction from the contact surface toward the receiving surface.

3. The terminal according to claim 2 , wherein the protrusion has a curvature that is larger at a distal end of the at least one connecting piece than at a base end of the at least one connecting piece.

4. The terminal according to claim 1 , wherein the protrusion includes a ridge section that extends in the extending direction.

5. The terminal according to claim 1 , wherein
the contact surface includes a recess that is recessed in a direction from the contact surface toward the receiving surface, and
the recess extends in the extending direction.

6. The terminal according to claim 1 , wherein an area of the abutting portion is substantially equal to or less than an area of the at least one connecting piece in a plan view.

7. A terminal comprising:
a terminal body including at least one connecting piece extending in an extending direction and being deformable, the at least one connecting piece including:
a contact surface contacting an electric wire; and
a receiving surface on an opposite side from the contact surface; and

a slider movable in the extending direction relative to the terminal body, wherein
the slider has a tube shape,
the slider is fitted on a section of the terminal body including the connecting piece,
the slider includes an abutting portion that abuts against the receiving surface of the at least one connecting piece and presses the at least one connecting piece against the electric wire that is disposed on the contact surface of the at least one connecting piece along the extending direction,
the abutting portion protrudes inward from an inner surface of a wall of the slider,
the abutting portion abuts against the connecting piece when the slider is slid on the terminal body to a contact position,
the at least one connecting piece includes a protrusion protruding from a section of the receiving surface in a direction from the contact surface toward the receiving surface, and
a curvature of the receiving surface of the protrusion is different from a curvature of a surface of the abutting portion facing the protrusion.

8. A terminal comprising:
a terminal body including at least one connecting piece extending in an extending direction and being deformable, the at least one connecting piece including:
a contact surface contacting an electric wire; and
a receiving surface on an opposite side from the contact surface; and

a slider movable in the extending direction relative to the terminal body, wherein
the slider has a tube shape,
the slider is fitted on a section of the terminal body including the connecting piece,
the slider includes an abutting portion that abuts against the receiving surface of the at least one connecting piece and presses the at least one connecting piece against the electric wire that is disposed on the contact surface of the at least one connecting piece along the extending direction,
the abutting portion protrudes inward from an inner surface of a wall of the slider,
the abutting portion abuts against the connecting piece when the slider is slid on the terminal body to a contact position,
the at least one connecting piece includes a protrusion protruding from a section of the receiving surface in a direction from the contact surface toward the receiving surface, and
in a cross-sectional view taken perpendicular to the extending direction at a contact point between the connecting piece and the abutting portion when the slider is slid to the contact position, a width of the connecting piece in contact with the abutting portion is less than a total width of the connecting piece.
