Claims
- 1. A press-connecting tool for electrically connecting a press-connecting blade having a U-shaped slot with a wire, the press connecting tool comprising:
- a press-connecting die having two die portions each including a substantially planar surface;
- an arcuate pressing portion formed on a surface of the press-connecting die facing in a press-connecting direction, a longitudinal length of the arcuate pressing portion corresponding to a longitudinal length of the wire; and
- a pair of opposed crush prevention walls, for preventing the wire from being crushed in the press-connecting direction, extending from each end of the arcuate pressing portion,
- wherein a relief groove, for receiving the press-connecting blade, is formed adjacent to the arcuate pressing portion and defined directly between the planar surfaces of the pair of opposed crush prevention walls, the die portions symmetrically disposed about the relief groove,
- wherein the wire is pressed into the U-shaped slot of the press-connecting blade by the arcuate pressing portions when the press-connecting die and the press-connecting blade are moved toward each other in the press-connecting direction, and
- wherein a wire pressing groove is defined by the crush prevention walls and a portion of the arcuate pressing portions adjacent to the crush prevention walls, the wire pressing groove contacting at least a half of an outer peripheral surface of the sheath.
- 2. The press-connecting tool of claim 1, wherein a distance between ends of the opposed crush prevention walls is substantially equal to an outer diameter of the wire, and a depth of the wire pressing groove is at least half of the outer diameter of the wire.
- 3. The press-connecting tool of claim 1, wherein a distance between the opposed crush prevention walls at a proximal portion is substantially equal to an outer diameter of the wire, wherein a distance between ends of the opposed crush prevention walls is larger than an outer diameter of the wire, and wherein a depth of the wire pressing groove is larger than a half of the outer diameter of the wire.
- 4. The press-connecting tool of claim 1, wherein the press-connecting blade includes a wire reception portion at an intermediate portion of the U-shaped slot, and wherein the wire reception portion has an arcuate pressing portion which faces the press-connecting die.
- 5. The press-connecting tool of claim 1, wherein guide portions, for facilitating the insertion of the press-connecting blade into the relief groove in the press-connecting die, are formed at end of the relief groove facing in the press-connecting direction.
- 6. The press-connecting tool of claim 1, wherein the arcuate pressing portion includes a slot fitting portion formed between the pair of opposed crush prevention walls.
- 7. A press-connecting tool for electrically connecting a press-connecting blade having a U-shaped slot with a wire, the press connecting tool comprising:
- a press-connecting die having two die portions each including a substantially planar surface;
- an arcuate pressing portion formed on a surface of the press-connecting die facing in a press-connecting direction, a longitudinal length of the arcuate pressing portion corresponding to a longitudinal length of the wire; and
- a pair of opposed crush prevention walls, for preventing the wire from being crushed in the press-connecting direction, extending from each end of the arcuate pressing portion,
- wherein a relief groove, for receiving the press-connecting blade, is formed adjacent to the arcuate pressing portion and is defined directly between the planar surfaces of the pair of opposed crush prevention walls, the die portions symmetrically disposed about the relief groove,
- wherein the wire is pressed into the U-shaped slot of the press-connecting blade by the arcuate pressing portions when the press-connecting die and the press-connecting blade are moved toward each other in the press-connecting direction, and
- wherein a wire pressing groove is defined by the crush prevention walls and a portion of the arcuate pressing portions adjacent to the crush prevention walls, a depth of the wire pressing groove being at least half a width of the wire pressing groove.
- 8. The press-connecting tool of claim 7, wherein a distance between ends of the opposed crush prevention walls is substantially equal to an outer diameter of the wire, and a depth of the wire pressing groove is at least half of the outer diameter of the wire.
- 9. The press-connecting tool of claim 7, wherein a distance between the opposed crush prevention walls at a proximal portion is substantially equal to an outer diameter of the wire, wherein a distance between ends of the opposed crush prevention walls is larger than an outer diameter of the wire, and wherein a depth of the wire pressing groove is larger than a half of the outer diameter of the wire.
- 10. The press-connecting tool of claim 7, wherein the press-connecting blade includes a wire reception portion at an intermediate portion of the U-shaped slot, and wherein the wire reception portion has an arcuate pressing portion which faces the press-connecting die.
- 11. The press-connecting tool of claim 7, wherein guide portions, for facilitating the insertion of the press-connecting blade into the relief groove in the press-connecting die, are formed at end of the relief groove facing in the press-connecting direction.
- 12. The press-connecting tool of claim 7, wherein the arcuate pressing portion includes a slot fitting portion formed between the pair of opposed crush preventing walls.
