Abstract

A terminal includes a terminal body and a slider. The terminal body is formed by processing a metal sheet. The terminal body is coupled to a front end of an electric wire with respect to an extending direction in which the electric wire extends. The terminal body holds the electric wire. The slider is slidable in the extending direction relative to the terminal body. The terminal body includes connecting tabs that includes contact surfaces contactable with the electric wire. Each of the connecting tabs has a cantilever shape. The slider includes pressing portions that press the connecting tabs so that the connecting tabs deform and the contact surfaces contact the electric wire when the slider is slid. The connecting tabs include burrs that are produced during processing of the metal sheet. The burrs protrude from the contact surfaces toward the electric wire.

First claim

The invention claimed is:

1. A terminal comprising:
a terminal body formed by processing a metal sheet, the terminal body being coupled to a front end of an electric wire with respect to an extending direction in which the electric wire extends and holding the electric wire, the terminal body including connecting tabs, the connecting tabs including contact surfaces contactable with the electric wire, each of the connecting tabs having a cantilever shape; and
a slider slidable in the extending direction relative to the terminal body, the slider including pressing portions that press the connecting tabs so that the connecting tabs deform and the contact surfaces contact the electric wire when the slider is slid, wherein
a direction in which the slider slides relative to the terminal body is equal to the inserting direction in which the electric wire is inserted into the terminal body,
the connecting tabs include burrs that are produced during processing of the metal sheet,
the burrs protrude from the contact surfaces toward the electric wire,
the slider has a rectangular tube shape that extends in the extending direction in which the electric wire extends,
the slider includes an upper wall, a lower wall that is opposite to the upper wall and two side walls that each connect the upper wall and the lower wall,
each of the upper wall and the lower wall has a respective pressing portion of the pressing portions, and
neither of the two side walls has a pressing portion.

2. The terminal according to claim 1 , wherein
the contact surfaces of the connecting tabs are opposite to each other, and
the slider has a tubular shape to cover the connecting tabs from an outer side.

3. The terminal according to claim 1 , wherein
the pressing portions protrude inward in the slider,
the slider includes a narrow portion and a wide portion,
the narrow portion of the slider has a less internal dimension in a pressing direction in which the pressing portions press the connecting tabs,
the wide portion is closer to a front than the pressing portions with respect to an inserting direction in which the electric wire is inserted into the terminal body, and
the wide portion of the slider has a greater internal dimension in the pressing direction than the less internal dimension of the narrow portion.

4. A terminal comprising:
a terminal body formed by processing a metal sheet, the terminal body being coupled to a front end of an electric wire with respect to an extending direction in which the electric wire extends and holding the electric wire, the terminal body including connecting tabs, the connecting tabs including contact surfaces contactable with the electric wire, each of the connecting tabs having a cantilever shape; and
a slider slidable in the extending direction relative to the terminal body, the slider including pressing portions that press the connecting tabs so that the connecting tabs deform and the contact surfaces contact the electric wire when the slider is slid, wherein
a direction in which the slider slides relative to the terminal body is equal to the inserting direction in which the electric wire is inserted into the terminal body,
the connecting tabs include burrs that are produced during processing of the metal sheet,
the burrs protrude from the contact surfaces toward the electric wire,
the contact surfaces of the connecting tabs are opposite to each other,
the slider has a tubular shape to cover the connecting tabs from an outer side,
the connecting tabs include folded portions that are formed by folding sections of the metal sheet,
the folded portions include sections of the contact surfaces that contact the electric wire, and
the burrs protrude from the sections of the contact surfaces toward the electric wire.

5. The terminal according to claim 4 , wherein
the connecting tabs are parallel to each other,
the contact surfaces are opposite to each other, and
the folded portions are displaced from each other in an inserting direction in which the electric wire is inserted into the terminal body on the contact surfaces that are opposite to each other.

6. The terminal according to claim 5 , wherein
the burrs are at edges of the folded portions of the connecting tabs being displaced from each other, and
the edges of the folded portions are opposite to each other.

7. The terminal according to claim 4 , wherein
the pressing portions protrude inward in the slider,
the slider includes a narrow portion and a wide portion,
the narrow portion of the slider has a less internal dimension in a pressing direction in which the pressing portions press the connecting tabs,
the wide portion is closer to a front than the pressing portions with respect to an inserting direction in which the electric wire is inserted into the terminal body, and
the wide portion of the slider has a greater internal dimension in the pressing direction than the less internal dimension of the narrow portion.
