Abstract

A production method for a terminal includes: a first pressing step for pressing a parent material plate made of a conductive metal and punching out a prescribed shape; a second pressing step following the first pressing step, for bending the plate of prescribed shape, and forming a terminal provided with a box part onto the front surface of which opens a terminal insertion port into which a partner terminal is inserted, and a spring contact part arranged inside the box part; and a plating step following the second pressing step, for plating at least the spring contact part with a conductive metal.

First claim

What is claimed is:

1. A production method for a terminal, comprising:
first pressing a parent material plate made of a conductive metal and punching out a prescribed shape;
second pressing following the first pressing, the second pressing bending the plate punched in the prescribed shape, and forming the terminal provided with a box part onto a front surface of which opens a terminal insertion port into which a partner terminal is inserted, and a spring contact part arranged inside the box part, the spring contact part to be contacted to the partner terminal, inserted from the terminal insertion port into the box part, by a flexural returning force; and
plating following the second pressing, the plating at least the spring contact part with a conductive metal by jetting plating liquid inside the box part using a nozzle inserted into the box part;
wherein the plating using the nozzle inserted into the box part comprises inserting the nozzle into the box part through the terminal insertion port and jetting the plating liquid through the inserted nozzle, thereby plating at least the spring contact part.

2. The production method for the terminal of claim 1 , wherein the plating using the nozzle inserted into the box part comprises inserting the nozzle to jet the plating liquid through a plating-utility opening provided in a face of the box part, the face facing the spring contact part, thereby plating at least the spring contact part.

3. The production method for the terminal of claim 2 , wherein
the plating-utility opening is arranged in a portion of a terminal contact part provided on the face of the box part, the terminal contact part to be contacted to the partner terminal which is inserted from the terminal insertion port into the box part, the portion facing the spring contact part, and
the plating using the nozzle inserted into the box part further comprises inserting the nozzle to face the spring contact part through the plating-utility opening and jetting the plating liquid to at least the spring contact part.

4. The production method for the terminal of claim 2 , wherein
the plating-utility opening is arranged in a portion on the face of the box part, the portion being different from a terminal contact part provided on the face of the box part, the terminal contact part to be contacted to the partner terminal which is inserted from the terminal insertion port into the box part, and
the plating using the nozzle inserted into the box part further comprises inserting the nozzle to enter through the plating-utility opening and jetting the plating liquid to at least the spring contact part.

5. A terminal formed by pressing a parent material plate made of a conductive metal to punch out a prescribed shape and bending the plate of the prescribed shape to form the terminal, the terminal comprising:
a box part onto a front surface of which opens a terminal insertion port into which a partner terminal is inserted; and
a spring contact part arranged inside the box part, the spring contact part to be contacted to the partner terminal inserted from the terminal insertion port into the box part, by a flexural returning force,
wherein at least the spring contact part inside the box part is plated with a conductive metal by jetting plating liquid inside the box part using a nozzle inserted into the box part;
wherein at least the spring contact part is plated by inserting the nozzle to enter into the box part through the terminal insertion port and jetting the plating liquid through the inserted nozzle.

6. The terminal of claim 5 , wherein
a face of the box part is provided with a plating-utility opening, the face facing the spring contact part, and
at least the spring contact part is plated by inserting the nozzle into the plating-utility opening to jet the plating liquid.

7. The terminal of claim 6 , wherein the plating-utility opening is arranged in a portion of a terminal contact part provided on the face of the box part, the terminal contact part to be contacted to the partner terminal which is inserted from the terminal insertion port into the box part, the portion facing the spring contact part.

8. The terminal of claim 6 , wherein the plating-utility opening is arranged in a portion on the face of the box part, the portion being different from a terminal contact part provided on the face of the box part, the terminal contact part to be contacted to the partner terminal which is inserted from the terminal insertion port into the box part.
