Abstract

A die extended in the service life. An anvil includes a base portion and a protruding portion, and further, includes a wall portion that is connected to rear surfaces of the base portion and the protruding portion. The wall portion extends further upward than the base portion, and extends further leftward and rightward than the protruding portion. Therefore, the rigidity of the protruding portion in a left-right direction is high.

Claims

1. A die that crimps a contact in cooperation with a mating die to thereby fix the contact on an electric wire, comprising:

a base portion;

a protruding portion that is formed on said base portion in a manner protruding upward from said base portion, and can be inserted in a receiving space of the mating die; and

a wall portion that is connected to front surfaces, rear surfaces, or front and rear surfaces of said base portion and said protruding portion,

wherein, said wall portion extends further upward than said base portion, and extends further in at least one of leftward and rightward directions than said protruding portion.

2. The die according to claim 1, wherein said wall portion is plate-shaped.

3. The die according to claim 1, wherein an upper surface of said protruding portion, on which the contact is supported, is formed with a dent,

wherein said wail portion is formed with a flat surface that is located at a level lower than the upper surface of said protruding portion, and is adjacent to the upper surface in a front-rear direction of said protruding portion, and

wherein one end of the flat surface in the front-rear direction is formed with a cutting blade for cutting a supporting arm portion of a carrier that supports the contact.

4. The die according to claim 2, wherein an upper surface of said protruding portion, on which the contact is supported, is formed with a dent,

wherein said wall portion is formed with a flat surface that is located at a level lower than the upper surface of said protruding portion, and is adjacent to the upper surface in a front-rear direction of said protruding portion, and

wherein one end of the flat stir face in the front-rear direction is formed with, a cutting blade for cutting a supporting arm portion of a carrier that supports the contact.

5. The die according to claim 3, wherein a dimension of the flat surface of said wall portion in a left-right direction of said protruding portion is larger than a dimension of the upper surface of said protruding portion in the left-right direction.

6. The die according to claim 4, wherein a dimension of the flat surface of said wall portion in a left-right direction of said protruding portion is larger than a dimension of the upper surface of said protruding portion in the left-right direction.

7. The die according to claim 3, wherein said wall portion has inclined surfaces formed in a manner continuous with the flat surface such that the inclined surfaces are inclined downward from the flat surface as the inclined surfaces extend away from the flat surface in the left-right direction.

8. The die according to claim 4, wherein said wall portion has inclined surfaces formed in a manner continuous with the flat surface such that the inclined surfaces are inclined downward from the flat surface as the inclined surfaces extend away from the flat surface in the left-right direction.

9. The die according to claim 5, wherein said wall portion has inclined surfaces formed in a manner continuous with the flat surface such that the inclined surfaces are inclined downward from the flat surface as the inclined surfaces extend away from the flat surface in the left-right direction.

10. The die according to claim 6, wherein said wall portion has inclined surfaces formed in a manner continuous with the flat surface such that the inclined surfaces are inclined downward from the flat surface as the inclined surfaces extend, away from the flat surface in the left-right direction.

11. A press apparatus including a die that crimps a contact in cooperation with a mating die to thereby fix the contact on an electric wire, the die comprising:

a base portion;

a protruding portion that is formed on said base portion in a manner protruding upward from said base portion, and can be inserted in a receiving space of the mating die; and

a wall portion that is connected to front surfaces, rear surfaces, or front and rear surfaces of said base portion and said protruding portion,

wherein said wall portion extends further upward than said base portion, and extends further in at least one of leftward and rightwaxd directions than said protruding portion.

12. The press apparatus according to claims 11, wherein said wall portion is plate-shaped.
