Abstract

A connection terminal made of a metal sheet includes a body portion having a first edge and a second edge extending in a longitudinal direction of the body portion and opposite to each other in a transverse direction of the body portion, a first wing extending from the first edge, and a second wing extending from the second edge. The first wing and the second wing are opposite to each other in the transverse direction of the body portion. A length of the first wing extending from the first edge is greater than a length of the second wing extending from the second edge. An inner surface of each of the first wing, the second wing, and the body portion has a plurality of first grooves.

First claim

What is claimed is:

1 . A connection terminal made of a metal sheet, comprising:
a body portion having a first edge and a second edge extending in a longitudinal direction of the body portion and opposite to each other in a transverse direction of the body portion; a first wing extending from the first edge; and a second wing extending from the second edge, the first wing and the second wing are opposite to each other in the transverse direction of the body portion, a length of the first wing extending from the first edge is greater than a length of the second wing extending from the second edge, an inner surface of each of the first wing, the second wing, and the body portion has a plurality of first grooves.

2 . The connection terminal of claim 1 , wherein each first groove is a slot extending in the transverse direction in the first wing, the second wing, and the body portion.

3 . The connection terminal of claim 2 , wherein an edge of each first groove has a first burr extending away from the inner surface of each of the first wing, the second wing, and the body portion.

4 . The connection terminal of claim 1 , further comprising a third wing extending from the second edge and a fourth wing extending from the first edge.

5 . The connection terminal of claim 4 , wherein the third wing is opposite the fourth wing in the transverse direction of the body portion.

6 . The connection terminal of claim 5 , wherein a length of the third wing extending from the second edge is greater than a length of the fourth wing extending from the first edge.

7 . The connection terminal of claim 6 , wherein the first wing and the fourth wing are disposed alternately on the first edge and the second wing and the third wing are disposed alternately on the second edge.

8 . The connection terminal of claim 7 , wherein an inner surface of each of the third wing and the fourth wing has a plurality of second grooves.

9 . The connection terminal of claim 8 , wherein each second groove is a slot extending in the transverse direction on the third wing, the fourth wing, and the body portion.

10 . The connection terminal of claim 9 , wherein an edge of each second groove has a second burr extending away from the inner surface of each of the third wing, the fourth wing, and the body portion.

11 . The connection terminal of claim 1 , wherein the body portion is pre-bent to have a substantially U-shaped cross section.

12 . The connection terminal of claim 4 , wherein an outer surface of a free end of each of the first wing, the second wing, the third wing, and the fourth wing has a slope.

13 . A method of connecting a plurality of wires, comprising:
providing a connection terminal made of a metal sheet and including a body portion having a first edge and a second edge extending in a longitudinal direction of the body portion and opposite to each other in a transverse direction of the body portion, a first wing extending from the first edge, and a second wing extending from the second edge, the first wing and the second wing are opposite to each other in the transverse direction of the body portion, a length of the first wing extending from the first edge is greater than a length of the second wing extending from the second edge, an inner surface of each of the first wing, the second wing, and the body portion has a plurality of first grooves; pre-bending the body portion as a substantially U-shaped cross-section; placing a portion of the plurality of wires within the body portion; and pressing the connection terminal with a pressing die, the pressing die has an opening having a substantially U-shaped cross section, the first wing and the second wing enter the opening, the first wing and the second wing are bent toward the body portion so as to crimp the wires within the connection terminal as the pressing die presses the connection terminal against a support portion, the first wing is located outside the second wing after bending.

14 . The method of claim 13 , wherein a plurality of guiding grooves having different slopes are provided on a pair of sidewalls of the opening of the pressing die.

15 . The method of claim 14 , wherein the second wing is bent toward the body portion prior to the first wing as the pressing die presses the connection terminal against the support portion.

16 . A pressing die adapted to press a connection terminal, comprising:
an opening having a substantially U-shaped cross section, a first wing and a second wing of the connection terminal enter the opening, the first wing and the second wing are bent toward a body portion of the connection terminal so as to crimp a wire within the connection terminal as the pressing die presses the connection terminal against a support portion, the first wing is located outside the second wing after bending.

17 . The pressing die of claim 16 , further comprising a plurality of guiding grooves having different slopes provided on a pair of sidewalls of the opening.

18 . The pressing die of claim 17 , wherein the second wing is bent toward the body portion prior to the first wing as the pressing die presses the connection terminal against the support portion.
